Description

The accounting system of radio communication

The invention relates to a kind of technique device, this device is by means of radio communication, particularly provides in the several data service from the music to the image of satellite communication with the individual data fragment with the basis or based on the efficient service rate data system of data cell.In the disclosed system, there is receiver to be used for avoiding undelegated use, makes the data, services expense effectively be chargeed and collect money the data that transmit via radio communication.A disclosed system wherein, can't to repay data, services in a scheduled time time-consuming when a receiver, his terminal meeting cloth one master station, that is lost efficacy under the control of a data set provider, so reached a kind of technology and come the operation of assitance data supplier with efficient mode management data service.

Utilize radio broadcasting, television broadcasting and the satellite communication of communications satellite just to be widely adopted in the world now.Because radio communication and having provide can use usually in the phone networking under the control of telephone exchange, hold the system that reaches the similar functions of communication as the basis with friendship, so service charge is kept accounts and to collect money in instant mode afterwards then be major subjects about radio communication.In television broadcasting, the note of every TV is taken and collected the charges, the example of now having set up is based on such supposition usually, begins from installation promptly that promptly channel correlation selected and that watch on television set charges to spectator or user.Among the system of present some satellite broadcast service of using, its signal scramble before transmission, and user's end is equipped with descrambler to separate scramble to the received signal.In this case, when installing, descrambler just uses fixing rate accounting with each.

Yet first above-mentioned system is the surface extreme difference when collecting service fee, is to decide according to this person of user wish fully because pay.Use second system of descrambler to increase the burden that descrambler must be installed on receiver, cause the extra cost of user.This may limit the growth of number of users.

The tradition charge system generally is every expense with fixed number, and the fair data class of looking is done the elasticity setting, does not also allow to pay with the resilient time.Just make data set provider can't broadcast data fragments thick and fast with commercial point of view like this than high cost.On the other hand, if data set provider has been limited the broadcasting that popular data become program, just can't be desirably on the business subscribers and expand.

In order on a phone networking, to use via the undelegated data of supervision in the traditional charge system under the data, services of two-way communication, user's end is sent and is uploaded one and requires master station, this requirement is the long use information of about 64 bits, has comprised user's identiflication number and data identification numbering.In response to the requirement of the information of use, master station can be sent one and license to use side.About 96 bits of its bit string of authorization signal are long, comprised to authorize numbering, user to know number numbering, and terminal number and data identification numbering are with the fail safe of guaranteeing to communicate by letter.The advantage that this system provides is one period short time promptly to be enough to link up the data of charge, because this data volume is very little.But then, this system encounters is to very serious problem: the mandate numbering to disguise oneself as legal to such an extent as to the too simple third party of these data is easy to decode.

As long as be one of step legal in the rule under considering in the exchanges data between user side and the master station, the problem that promptly do not have takes place.If yet be not in above-mentioned rule.Then the exchanges data of Shou Quaning can cause illegal data to be used.More particularly, when a user holds an initial proving program that bad intention is arranged, perhaps when an authorization signal is produced by the other-end of a non-master station, master station can't be managed the charging that still has many data slots that expense do not collect.In addition, whether this system need verify normally each data, services and pay, and makes the program of data, services complicated, and increases the burden of use side and master station.So, when the user deposits master station for several times when obtaining repeatedly data, services continuously, all to finish extra verification step at every turn.Make the connect hours increase extra time like this, and also descended with the efficient of conveying capacity master station.

An object of the present invention is to provide a charge system, allow the unit price of the fragment of the individual data that frequency and user according to access data receive correctly to charge, and do not need master station to collect the expense of every usefulness from the user.

Another object of the present invention provides a charge system, allows to utilize correctly to charge as supplier's master station with as the common code between recipient's the use side, makes the third party can't steal data.

The present invention still has another purpose to provide a mechanism, and it allows use side upload user mode and to allow master station obtain the user mode of use side in the specified time of master station, so that master station can be managed all use sides concentratedly.

In order to reach first purpose, the present invention comprises a master unit and a receiving element basically, and master unit is to be made of the master station computer that a conveyer and store several data, and receiving element in response to the several data kenel with executive program.Be stored in the user mode memory of The built-in by the identification code of master unit the execution data correspondence in the data that receive.According to the translation data that is transmitted by master unit with the set time, the identification code of system handles storage is periodically to determine service fee.

In said system, master unit and receiving element are to link via the class radio communication that is generally satellite communication, and (the karaoke that plays Karaoka, being interpreted as of English and cultural dictionary according to Longman " sung and as stress-relieving activity with the background music exercise that stores; normally in the bar ") data, television game data, and the then exchange betwixt of digitisation image data.One receiving element has stored the Identification Data that is relevant to the data that will handle and carry out from the several data that master unit sends in its user mode memory, and stored Identification Data calculate and basic expense.Comprised cost data to each Identification Data apart from the translation data that transmits from master unit with fixedly the time, and expense is periodically to calculate by means of the Identification Data of relatively translation data and storage.

Another configuration of reaching first purpose of the present invention is the user mode memory that the identification code that will be relevant to the execution data in the data of being received by receiving element is stored into receiving element, determine the frequency of utilization of each identification code, and the result is used as frequency data.Receiving element sees through message accounting binding that telephone wire and one and master unit be provided with simultaneously so that the cost data of each identification is stored a data form.Receiving element is given message accounting apart from uploading the frequency that is accumulated in the user mode memory through the rate data fixedly the time, and the message accounting now calculates the information service expense apart from the reference data form with fixedly the time.

The technological standpoint that above-mentioned configuration one is unique is that message accounting is with master unit and deposits setting.So message accounting has fixedly the time apart from the function of each receiving element being calculated its service charge.Receiving element has stored the frequency of utilization (occurrence frequency) for identification code in its user mode memory, this identification code is the data that will handle and carry out that are relevant to from the data that master unit comes, and frequency data are the bases that are used as charging.The function of the data form of message accounting is the reference table that calculates as expense, and the frequency data that are uploaded to message accounting are that the reference data form is handled, so that calculate the data, services expense under the distance fixedly the time.

For a technological standpoint of another device of reaching first purpose of the present invention is that the Frame that comes the data of independent unit is that the identification code of veriform data is disperseed, and has comprised a read/write device that is used for IC-card in acceptor unit.Receiving element collect to be carried out the identification code of data, and the data of the metering data of the accumulative total of identification code are write in the IC-card that inserts in read/write device, the data, services expense is accounted on the IC-card account, or with the service charge IC-card that writes direct.

The function that so is installed in the IC-card read/write device of receiving element is to read the content of the RAM (random access memory) that includes IC-card, and new data is write among the RAM.In the present invention one desirable embodiment, IC has stored and has been used for the data of calculated data service charge and uses historically, perhaps is used as the present account of IC-card when IC ends future as so-called prepaid card.Use in the historical configuration at storage data, these data are to deliver to master unit and by the calculating of its message accounting execution cost.As in the configuration of prepaid card, service charge is to be that the basis is decided according to the data form that is stored in the receiving element, then the accounts that upgrade is write in the IC-card at IC-card.

Another embodiment of the present invention is quoted a kind of configuration, wherein receiving element is provided with a user mode counter is relevant to the execution data in the data that received by receiving element with storage identification code, and wherein the acquisition of service charge data is by means of the expense translation data that transmitting terminal was transmitted with the set time and is stored in the user mode counting and gets according to the correlation of the identification code in the device.The data, services expense data now that is obtained converts the frequency data based on the CATV rate that gets by means of CATV (cable TV) the adaptation device control circuit of user side to: receiving element is uploaded to CATV with frequency data the station is provided: the CATV station will be downloaded to receiving element corresponding to the particular data of frequency data; And this download has replaced CATV data, services rate.

CATV (cable TV) adapts to the device control circuit service charge data transaction is become frequency data based on the CATV rate, and with frequency data via.CATV adaptation device is uploaded to CATV provides the station.Frequency data are that acceptor unit is used for notifying CATV that the expense of station according to frequency data is provided.The CATV supplier is the accounting routine separate processes of frequency data with normal payment data, and the data that will be relevant to frequency data are downloaded to receiver.So, the data, services expense of handling by CATV has replaced the data, services expense of handling satellite communication on function.

For reaching the purpose of the unauthorized use of avoiding data, the present invention allows master station to transmit several data with radio when the phone bond of setting up between master station and the use side and gives use side.Before handling particular data, use side is uploaded a requirement that comprises the use information of data identification number through telephone wire, and master station send a number series to use side.According to number series, the requirement of the use data that master station is more previous with rebuild the requirement of the use information of uploading again by use side according to number series, if both unanimities, master station is sent an authorization signal to use side through telephone wire.

Between master station and user's end, wired and wireless two kinds of links have been set up in the radio link, master station provides data to use side in the single communication mode, and telephone wire is avoided the undelegated use of data and carried out suitable data, services accounting routine being used in the two-way communication mode.Number series is to be used for avoiding the third party's unauthorized to use data, and allows a succession of step, makes and have only when use side is finished a coding according to normal procedure that master station is also licensed end and used specific data slot.The receiver of use side produces fen, and to have a function be to tie the data flow that the data of transmission and decoded data are sealed provides can be handled by CPU (CPU) by means of detecting or demodulation in radio link.One data again regenerating section to have a function be to be for data processing according to many data kenels, the handled data of data reproduction part are given in response to flowing from the receiver partial data by the CPU under being controlled in the control formula.Because the control formula is only just recovered when authorization signal is received by master station, so avoided undelegated data to use.

In addition, according to the present invention, master station has a database that stores mass data, and a customer data base, and customer data base is used for storing unique identification code of many subscriber units, uses the frequency of service, and the payment state data.In response to being still that the requirement of any receiving element of the data, services of not paying, master station transmit the data that are required and being unique identification code to receiving element.When access time of master station appointment and date, receiving element access master station, and master station is searched customer data base according to unique identification code.When not finding not pay accounts, master station notice receiving element is new data more, and these data are when to expire and access time next time about new service available life.When the accounts of finding not have in time to pay, master station notice receiving element is new data more, and this is when to expire and the next access time about a brief service available life.When the access time, fail to verify this paying usefulness, perhaps permanent what access the access time or before when identifying, master station is sent disablement signal and is given receiving element.

Between master station and use side, set up wired and wireless link.In wired link, master station provides data to use side in the single communication mode, and is two-way communication when using the radio link, to guarantee the proper charging work of using and carrying out suitable data, services of data.The customer data base of master station stores with the form of archives) be assigned to unique identification code in each of many use sides, the number of times of requirement, and the paying situation on the paying date of data, services.The function of customer data base is the reference data of conduct in the service failure mechanism of receiving terminal.Whether master station is searched customer data base and is paid with the checking use side on time.When the data, services expense is paid on time, master station update service available life, this is the time that use side more requires data, services.By means of next access time of indication and date, master station is obtained the checking step of next service charge paying again and is gathered.On the other hand, in the time of can not verifying when paying, being updated to the of short duration service available life and the notice on access time and date is next to arrive one of final needed step of service failure program.Other advantages of the present invention, and effective feature can be clearer together with accompanying drawing by the description below the present invention.It is also noted that " radio communication " that be used for text comprised satellite communication and ground communication, and " radio broadcasting " used herein comprises radio broadcasting and terrestrial broadcasting.

We will discuss embodiments of the invention with reference to the accompanying drawings now.Fig. 1 is the calcspar that shows the first embodiment of the present invention, has wherein quoted satellite communication.The first embodiment of the present invention comprises a communication satellite 1 at a planned orbit, is transmitting master unit 2, one receiving element 3, one charging passages 4, one public telephone networkings 5 and the circuit switching device 5as of side as master station.Receiving element 3 links with telephone switchboard 5a by charging passage 4.Though Fig. 1 shows single receiving element 3.A plurality of receiving elements can be arranged in parallel in practicality.As shown in Figure 2, unit 2 comprises a master computer 6 basically, database 7, one conveyers 8 under master computer 6 controls, and an antenna 9 of making the usefulness of satellite communication.If the transponder of satellite 1 utilizes fully, then multichannel broadcasting may be arranged by means of setting a plurality of channels.In this case, unit 2 specifies veriform data to give different passages, and transmits the multichannel signal to communication satellite 1.Several data can be assigned to a plurality of channels.For example, in Karaoke, tone can specify the relevant word of a channel then to be assigned to another channel; In the comvision recreation, data can be assigned to different passages with program.In these examples, the user has the right to choose of choosing channel.

With reference now to Fig. 3,, the structure of receiving element 3 will be retouched as follows in detail.One tuner 11 is via an antenna 10 receiving satellite signals, and this signal is 2 to be received and receiving the broadcasting again of amplifying from the unit by communication satellite 1.The signal of broadcasting can be the view data such as signal of video signal sum digit signal of video signal, and the numerical digit data such as Karaoke operation or computer game.We suppose that the structure that tuner 11 is had can have enough frequency ranges to make operation repetitive to hold a plurality of predetermined channels.Have such as the reception data processing block 12 of the storing mechanism of the class of buffer-stored and carry out basic functions, for example constitute the header of communication protocol and sufficient yard data flow such as each data processing of temporary transient storage when multichannel is handled simultaneously, and take out required data from the signal of receiving.The whole receiving element 3 of Controlled CPU (CPU) 13 controls receives data processing block 12 according to the handling procedure control that stores, and exports required data.One signal processing block 14 comprises a video signal processing circuit 14a with parallel framework, a Karaoke signal processing circuit 14b, and a video game signal processing circuit 14c, and the received signal of the corresponding form of each processing of circuit.Signal processing circuit has other output 15a, 15b, and 15c.For collecting image output, a display unit (not shown) simply is connected to image output 15a.For enjoying the comvision recreation, a video game device (not shown) simply is connected to video game output 15c.One control panel and display floater are denoted as 16 and 17.Button is arranged on control panel 16, is used for operating with reference to display floater 17 listed data choosing required data.Above-mentioned is to ask the basic structure of handling the receiving element 3 that receives data.Though this embodiment uses satellite communication, do not have substantial difference if quote ground communication.Logical main satellite 1 saves with regard to not needing, and must change antenna form to meet the frequency band requirement yet in the case.

What next discuss is the charge system of data, services.In Fig. 3,18 calculating of user mode memory and accumulating signal are handled each signal processing circuit 14a of block 14, the frequency of utilization of 14b and 14c.The result of accumulative total is used for fixedly the time apart from the calculation services expense.The data that can be used to calculate frequency of utilization are dispersed in the bit crossfire that is transmitted with the form of coded data.The data that picture is used to refer to for example Karaoke of data pattern and identification of video game and so on are the gauge outfits that insert in data frame.Handled by Controlled CPU 13 by the data that tuner 11 is received, control panel 16 is chosen the data form that will handle affairs then, and the data now of choosing is by the signal processing circuit 14a of correspondence, and 14b and 14c handle.Li data are to be stored in user mode memory bank 18 together with its data message form herein.The data that sender side was sent the unit service price of every kind of data with the fixed cycle are used as the data that convert.Controlled CPU 13 is utilized the frequency of utilization in the user mode memory 18 of being stored in of conversion data reduction identification code, and handles and the calculated data service charge with specified period.In this embodiment, though the different shape data have different unit prices, have only and want the data homomorphosis that same unit price is then arranged.Another distinct methods is other service to be that different prices is set on the basis for the basis but not with the data mode.User mode memory 18 is only by taking out identification code in the data frame, and organizes and store with the data form form.The conversion data of the representative unit price data streaming that receives by means of the conveyer side joint, user mode memory 18 do not have examine data defend lattice with the calculation services expense with the decision total price.In this embodiment, the data of indication unit price are not stored in the receiving element 3 in advance, but the transmission data of being used as the conveyer side bring, so that unit price can upgrade with the need.

The total price that is determined by receiving element 3 is via modulation demodulator 19 outputs as the usefulness of data communication, delivers to telephone switchboard 5a via charging passage 4 then.An example operation with charging passage 4, can use known system, wherein the function of telephone switchboard is to do data supplier's succedaneum, it collects the expense that is equivalent to use during the data, services of receiving from the user, and telephone switchboard deduction agency service expense back funds on account is paid to data set provider (conveyer side) then.In the case, when when the user charges, public telephone company takes data, services and adds in the normal telephone rate.Though in this embodiment, the data, services expense is added in the telephone rate of telephone switchboard 5a itself, also can allow the user pass through the master computer 6 of telephone wire access conveyer side so that the data, services expense is transmitted side with the set time notice conversely.In this embodiment, the cost data that is not to use person's side to bring with the conveyer side basically is that the calculated data service charge is come on the basis as the conversion data, and user's side is delivered to the conveyer side with the result.

Discuss now and two embodiment.Fig. 4 is the calcspar that approximately shows second embodiment, and this example is quoted satellite communication again again.Fig. 4 has shown a communication satellite 31, one translator unit 32, is used for the message accounting 32b of calculation services expense, a receiving element 33, one telephone wires 34, and a phone networking 35.It is to be connected via phone networking 35 each other that calculation element 32b picks up unit 33 with reception.The master unit 32a here is then structurally identical with first embodiment shown in Fig. 2.Again, first among receiver and Fig. 3

Embodiment is identical.

Below to describe be to use receiving element 33 to receive data the time the configuration of charging.The basic fundamental of second embodiment is identical with first embodiment generally.Technical difference is that together with the data of having handled, user mode memory 18 stores the frequency of utilization of every kind of data kenel.For example in a period of time, Karaoke is used N time and video game has been played M time, and user mode memory 18 is to store the Karaoke sign indicating number with the frequency data form to follow outstanding M with the sign indicating number of work N and video game.In addition, not only different data kenels is set different prices, also data and another data are looked the different prices of its content setting.Each data slot is put on an identification code.The frequency of each different identification code all stores.This allows more accurate the charging, has quoted satellite communication.Yet same for first embodiment, promptly use other radio communication mechanism to replace as FM (frequency modulation), the basic framework of this embodiment does not change.

State as the front, being stored in this is to export via the modulation demodulator as data communication as the data frequency of utilization in the user mode memory 18 (Fig. 3) of the inside block of receiving element 33, is sent to the message accounting 32b that is controlled by translator unit 32 via telephone wire then.There are two kinds of methods to can be used for expense device 32b with the receive frequency data.The firstth, receiving element 33 access message accounting 32b are to send frequency data.Second method is that Charging Detail Record unit 32b access receiving element 33 is so that receiving element 33 is uploaded to message accounting 32b with stored frequency data of this moment.In this embodiment, any of available both methods.Yet first method provides a better simply arrangement, and wherein the Controlled CPU of receiving element 33 in receiving element 33 rolled over the set time access message accounting 32b that internal clocking is controlled.Yet when the big number of number of user's receiving element 33, if each receiving element 33 is attempted access independently, the congested access time has been reduced freight volume in fact.On the other hand, though second aspect needs complicated arrangement, the method for message accounting 32b access receiving element 33 allows the access time of message accounting 32b controlling receiver unit 33.So, second method has been exempted the problem of freight volume.The number of user's receiving element can be considered and choose which kind of method.

Frequency data such as the above-mentioned message accounting 32b service charge that is uploaded to are that each receiving element 33 is calculated.Message accounting 32b has the data form of the unit price that comprises each identification code.When frequency data were imported, message accounting 32b was connected they and data form to calculate sum total.The data, services expense of sum total is via coming in the described suitable mechanism of first embodiment each user's charge.

The 3rd embodiment is discussed now.Fig. 5 approximately shows the third embodiment of the present invention.In Fig. 5, quote satellite again as communication.Shown in Figure 5 is communication satellite 41, is used for transmitting with data mode the master unit 42 of the usefulness of data and a receiving element 43.Master unit 42 has the structure same with first embodiment.The internal structure of receiving element 43 is shown in Fig. 6.The basic structure of the receiving element 43 among Fig. 6 almost receiving element with first embodiment is identical.Receiving element 43 comprises a reception antenna basically, and a tuner 42, receives data processing block 53, one Controlled CPU 54, and a signal processing block 55.Signal processing block 55 comprises a video signal processing circuit 55a with parallel Chinese holly frame, a Karaoke signal processing circuit 55b, a video game signal processing circuit 55c, and fellow, the kenel of the received signal of each processing of circuit correspondence.Signal processing circuit has output 56a respectively, 56b and 56c.Being included in again has a control panel 57 and a display floater 58 in the receiving element 43.Memory block under Controlled CPU 54 control has a data form and comprises data, services expense to each data slot.The calculating of data expense is to carry out with reference to this data form.Being included in again has an IC-card read/write device 59a and the IC-card 59b that can insert among the IC-card read/write device 59a in the receiving element 43.What go into IC-card 59b in advance is user's data such as user's name, address, birthday and fellow, and also has maximum available quantity in a prepaid card.If attempt receives data, services when IC-card 59b inserts IC-card read/write device 59b, reception data processing block 53 is abandoned the data of being received by reception antenna 51 automatically and can not handled.

Below describe in detail when the user with receiving element when obtaining data, how to make billing operation.IC-card 59b has stored the value of maximum available quantity, and has so-called prepaid card identical functions.When a user buys IC-card, write in the IC-card corresponding to its maximum available quantity of buying the amount of money.So, charge operates in when buying and has finished.When IC-card inserted, IC-card read/write device 59a read present available quantity, and in checking) receive data processing block 53 still in wait state behind the available quantity at present.

The data of calculating frequency of utilization are to insert in the bit crossfire of the data that transmitted by master unit 42.For example, the identification code of the kenel of the data of indication as Karaoke or video game is to insert in the data frame.The signal of going out is received by tuner, required signal by optionally by the signal processing circuit 55a of correspondence, 55b, or 55c handles.When the signal of wanting received, the data form of Controlled CPU 54 reference data expenses calculated the data, services expense corresponding to identification code.An inferior available quantity is the present available quantity that stores among the IC-card 59b is deducted described data, services expense and to calculate and get, and an inferior available quantity is to write IC-card 59b via IC-card read/write device 59a.Number in the IC-card is by means of deducting the data, services expense from previous available quantity and the result suitably being upgraded as ensuing available quantity.

Following system can regard the modification of the 3rd embodiment as.The structure of this system has communication satellite, master unit, and the receiving element among Fig. 4, and the structure of this receiving element is as shown in Figure 7.The same Ref. No. of Fig. 7 and Fig. 6 has said function.Difference is to introduce among Fig. 7 with the modulation demodulation of date information strong 60.-IC-card read/write device 59a calculates the frequency of utilization for each signal processing circuit in signal processing block 55, and the user mode data are deposited among the IC-card 59b.Unlike the method for being quoted among the 3rd embodiment, the available quantity of IC-card 59b does not upgrade, but the frequency data of the identification code of the data, services that is used are written in the IC-card.The data that the conveyer side group is collected in IC-card and determination data expense regularly.For example when a certain when specific apart from, N is used in Karaoke and video game has been played M time, IC-card 95b has stored for example to play Karaoka and has reached video game M time for N time as frequency data.In addition, not only the data of different kenels can be set different prices, and look its content and can set a data, services and with another person different prices are arranged, and each data slot indicates identification code.The identification code frequency is stored.This allows more accurately to charge, and response data is important and pouplarity.

For each the identification code frequency data that is stored among the IC-card 59b is to make storage protection by reserce cell, even IC-card 59b takes out no problem from IC-card read/write device 59a.When inserting IC-card 59b next time, the previous data that store are via modulation demodulator 60 outputs as the usefulness of data communication, then via the telephone wire of Fig. 4 be sent to the control of conveyer side message accounting 32b.The same have two kinds of methods to can be used for message accounting 32 to receive the frequency data together with Fig. 4 description again.The arbitrary of two kinds of methods can select for use.

Next the note charge system of Miao Shuing, wherein CATV (cable TV) networking is used to charge and collect the data expense of being served by broadcasting satellite or communication satellite.Fig. 8 shows that 71, one in a communication satellite is used for transmitting with multiple medium the translator unit 72 of several data fragment and a receiving element 73.One two-way communication link builds between receiving element 73 and the CATV station 74.The basic structure of translator unit 72 is identical with transmitter unit among Fig. 2.

The internal structure of receiving element 73 is to discuss with reference to figure 9.In Fig. 3 and Fig. 9, use same Ref. No. to indicate same block with said function.User mode counter 81 countings are at each signal processing circuit 14a of signal processing block 14, and the service of 14b and 14c utilizes frequency, that is the service frequency of utilization of every kind of data type, the frequency data of store results then.Utilizing the data computation cost data that stores is the expense conversion data that regularly transmit based on conveyer 72.The data of counting service frequency of utilization, that is counting is to insert among the signal data of translator unit 72 transmission in the identification code data of the service frequency of utilization of each signal processing circuit.The designation data kenel is for example played Karaoka and the identification code of video game is to insert in the data frame.The data that received by tuner 11 are by 13 processing of Controlled CPU (CPU), and control panel 16 is to be used for the people to choose the data of wanting, and these data are the signal processing circuit 14a by correspondence, and 14b and 14c handle.Only be relevant to the data of processing, user mode 81 stores the service frequency of utilization of every kind of data kenel, that is the accumulation number of identification code.For example in one period scheduled time, Karaoke is used N time and video game has been played M time, 81 pairs in user mode counter deposited such as played Karaoka and video game M as frequency data.The identification code of accumulative total and to change data by the expense that transmission unit 72 regularly transmits be to interrelate and the reference data form is handled, and cost data is regularly apart from obtaining with as the data, services expense with one.

After finishing calculating, cost data is delivered to CATV and is adapted to device control circuit 82.CATV adapts to device control circuit 82 to be carried out the cost data of data transaction one-tenth based on the frequency of the data, services charge system of the CATV of user's use.With as a parameter.For example use supposition once equals the amount of X.For example, when the whole data use amount of satellite communication is 100X, CATV adapts to device control circuit 82 and converts the amount of 100X to 100 with as frequency data.Frequency data are put on the predetermined unique identification sign indicating number that is assigned to use side 73, and are uploaded to CATV station 74 via CATV adaptation device 83.

CATV station 74 is provided with the charging passage of a special use except normal data channel.This special-purpose charging road is not to be used for presenting storage to give the user as the data of the class of program.And this special-purpose charging normally is used for collecting the information service expense of being held (receiving element) 73 data that receive and handle by the user.When the user holds 73 to upload frequency data and stand 74 the time to CATV, CATV station 74 is downloaded corresponding to the information of frequency data via the special use charging passage at CATV networking and is held 73 to the user.For example, each data slot of being handled by dedicated channel is by with 1 times, and 10 times, or 100 times different content makes up.When for example 120 times frequency data were uploaded, information shelves and two the information shelves that equal 10 times that equal 100 times were chosen at CATV station 74, combined then again these news files to be delivered to the user and hold 73.The data, services expense of this permission in the CATV networking is substituted in the information service expense in the satellite communication.As mentioned above, because the logical information that is not used to provide in special-purpose charging road, so the predetermined picture exchange between CATV station and user's end is enough, any mechanism all is acceptable as long as it allows the user of receiving element to verify that the information charge of collection is to finish on time.The kenel of information and the length of information on services should not influence the present invention.

In the common example of the charge system of normal CATV 74, the user is that the user watches or the All Time of user's service of receiving information calculates to the expense of program.That is the user at CATV networking charges according to the frequency with resulting information service.Tentation data according to frequency data is to deliver to receiving element, and the user charges as the amount that equals the CATV service charge that the user obtains the CATV service.Says that in this embodiment, receiving element access CATV station 74 is with the notice CATV frequency of 74 information services of standing bright gram, 74 collect the data, services expense of satellite communication for the information service provider and allow CATV to stand afterwards.For the purposes of the present invention, calculate just enough for CATV station 74 based on the service fee of frequency information.When frequency data when receiving element 73 is uploaded, in to CATV station 74,, all enough download simple and fixing information and respond regardless of the size of frequency data, confirm at least that with permission receiving element 73 it 74 is at the charging state that CATV stands.CATV 74, and keeps accounts with frequency data calculation services expense to each recipient.For brevity, the service charge accounting routine is this heavy covering.By the cost data that receiving element 73 calculated is to convert CATV network services expense to and as frequency data, and the CATV active station is collected from user side and comprised that CATV service charge own adds the money for the information service expense of the conversion of radio communication informant's radio communication.CATV service charge of CATV active station now deduction from the sum of collecting own and agency's service charge, and pay the operator of delivery unit 72 that is informant with surplus.

Next the technology of raising the price is discussed, it be used for avoiding by as the undelegated use of the information that above-mentioned satellite communication or satellite broadcasting transmitted.Figure 10 is the calcspar that is used for this receiving element of raising the price.One CPU91 handles the information that transmits and receive and controls whole receiving element.Detected and demodulation by the signal that antenna 92 receives, and by a receiver square 93 digitisations, the data streaming of digitisation inputs to CPU91 with the radio wave pattern.CPU91 also controls a succession of output step, comprises control one modulation demodulator 94 and fee charging signal is uploaded to master station by telephone wire 95.In this embodiment, transmitted by the radio communication of master station with the multiple information of data flow pattern, and metering data is to exchange on telephone wire 95 by modulation demodulator 94 between master station and receiving element via for example satellite communication.One information regeneration block 96 is carried out required regeneration and display routine, looks the kenel such as the television game data of data flow, karaoke data, image data and lteral data etc. and decide.Data now after the processing exports a suitable output device (not shown) to via output 97.If receiving element 93 is directly received the numerical digit sign indicating number and is made for output, data reproduction block 96 can not be regenerated.Only the CPU91 under number is controlled by control program handled, and its output just becomes significant data.Control program memory 98 stores a kind of formula and allows CPU91 data-driven kenel to handle from the dateout crossfire that receives block 93.In order from control program memory 98, to take out the control formula, CPU91 need notify master station it to be processed be which kind of data kenel, and receive authorization signal from master station afterwards.This action is to be decided by the content that the code sequence that stores code sequence is sacrificed one's life for memory 100 and stored the code formula memory 100 of coded program.So, because receiving element was notified master station data kenel to be processed before data processing.So master station can be carried out suitable billing operation.The program that is stored in the coded sequence memory 99 not only can be held execution the user, also can carry out at master station.

The rule that will write yard sequence memory 99 is below described.

The example of the program of data message crossfire coding is as follows:

1: with 1 value that is added to even bit tuple position, with the value of odd bits tuple position 1 bit that moves right.

2: the value of even bit tuple position is subtracted 2, with the value of odd bits tuple position to 1 bit that moves to left.

……

... 100: the sign indicating number formula

......

... 499: topmost 4 bits is on duty 2, and the value of 4 bits that will be lower adds 1.500: the value of 4 bits that will go up moves to right, and the value of 4 bits that will be lower moves to left.

" coded program " is to be specified in 100.If coded program itself as being sent into reception in this situation, does not just need coded program memory 100 yet.In order to shorten the delivery time, need the coded program memory to store coded program.So, be more important if shorten the delivery time, subtract the freight volume of the end on telephone wire so that save time and be unlikely, coded program preferably is stored in the coded program memory 100.If not so, then coded program is each the reception and transmission.Two kinds of arrangements can be selected to use with the compliance with system requirement.

In order to use the data that receive, use side to send the bit crossfire of " information that requirement is used ", has comprised " authorize numbering, user's identification is numbered, and terminating machine is numbered, the information identification numbering " by telephone wire access master station.That master station is responded and the information that checking requires to use be correct order and user do not have unpaid accounts and user's numbering and other data all errorless after, send above-mentioned coded sequence and give use side by downloading telephone wire.The sign indicating number sequence number is not mixed and disorderly order always, successively decreases repeatedly and can be, and this order can be periodically updated by the counter of master station in addition.Update cycle is to be set arbitrarily by the master station side.Compared with traditional mode that allows yard sequence number send with its order, this kind arrangement needs the extra delivery time because data volume increases.Though and this kind arrangement provides better information privacy.The present volume of traffic of master station persistent surveillance, and sometimes when traffic measured certain threshold value, stop to upgrade a sign indicating number sequence and be selected.In to a certain degree, avoid like this lowering owing to coding makes the volume of traffic.The instructions for use information that the sign indicating number sequence that receiving element heavily send to be provided according to master station is encoded is to master station.The use information requirements that master station will have been encoded with the reversal procedure of coded program are decoded.The master station use information requirements that will decode and comparing of before having received then.If both unanimities, master station are confirmed receiving element and carried out correct coded program, send authorization signal then and use information service to authorize receiving element.This authorization signal is also raised the price according to coded program.After above-mentioned steps had all been finished, the CPU91 of receiving element was allowed to abolish the gauge 98 from control program and takes out control program.Based on control program, CPU91 can handle the data streaming that is obtained by receiver block 93.

Coding techniques described above is avoided the free or unauthorized use data, services of user.The safe availability guaranteed of technology thus, data set provider can be easy to utilize radio communication or radio broadcasting to come process information.If the viewpoint of the fail safe that another will be considered be the user of receiving element after a period of time of not paying, the method that makes its inefficacy is provided.The numbering technology is discussed together with this again again.Figure 11 shows provides the calcspar terminal control unit 111 of above-mentioned purpose receiving element to comprise a CPU as core, and the control whole unit is handled the data that transmit and receive simultaneously.The signal that is received by antenna 112 with the radio wave form is to be amplified then by the conversion of a transducer 113 working frequencies, and is detected by a detector 114, and analog/digital conversion (if original signal that transmits is the numerical digit signal) is made in channel selection then.If the signal of receiving is scramble, a descrambler 115 is separated scramble with the output signal of detector 114.If the signal that receives is scramble not, by the simple descrambler 115 of crossing of signal of detector 114 outputs.When the analog signal of for example signal of video signal of the signal of receiving or sound signal and so on, detector 114 is directly delivered to a signal of video signal transducer 116 and a sound signal transducer 117 with its output, and the output device of display unit for example or amplifier and so on is then delivered in its output respectively.When the signal that receives was the digital image signal, it was handled by terminal control unit 111, and this controller 111 is delivered to signal of video signal transducer 116 with its output as signal of video signal.Signal of video signal transducer 116 converts image data to signal of video signal and gives output device.When the signal that receives was midi signal or PCM (pulse-code modulation) signal, data were to be handled by terminal control unit 111.Data after the processing export sound signal transducer 117 to, and the data transaction after now transducer 117 will be handled becomes the analogy sound signal to give demonstration master unit or amplifier.When the signal of receiving is other numerical digit signals, it via interface 18 be sent to can with the external device of the Signal Matching of receiving.The signal that detector 114 differences are received is numerical digit signal or analog signal.Memory 119 comprise be used for stored routine row and each receiving element be unique data usefulness ROM (read only memory) and as the RAM (random access memory) of the usefulness of the temporary transient buffer storage that stores.The coded sequence of having described is to write in the ROM zone.

Charge system in this embodiment is to operate by public telephone line 121 via a modulation demodulator 120.Figure 12 has shown master station in this embodiment.One database 122 has stored many data under the control of master computer 123.When a plurality of receiving elements require, main calculator 123 reads the individual data of the correspondence of each receiving element from database 123, it is to read or the order not considering to require to arrive carries out with random fashion with the order that requires to arrive, and data are seen through special line 124 delivers to ground station 125.Ground station 125 looks required radio wave pattern and carries out necessary modulation and conversion, and for example the modulation of satellite or frequency modulation modulation are sent varying signal via antenna 126 then.Database 122 comprises a User Information Database, it together with each receiving element identification code and each receiver user whether when information charge please money normal pay etc. information etc. and suitably upgrading.One network controller 127 is connected to receiving element by special line or public telephone line.The rule that transmits and receive can be set arbitrarily.The signal of no matter handling is an analog or digital, and principle of the present invention is still effective basically.

A succession of exchanges data is to be shown between receiving element and the master station as Figure 11 and 12 respectively to carry out.In order to take out the required information of receiving element, receiving element sees through telephone wire and makes one and require to give master station, and the master station now is to desired information search database 122 and read.Master station is sent the data of requirement together with the acceptor unit identification code of doing to require via ground station 125 then.In the case, were it not for the identification code that discovery meets, the data of receiving can not be used, and so avoid the third party to use information without permission.Such technology is widely used in the association service of telephone communication at present.The present invention is not this technology of unconditional reception, but by means of introduce step and the improvement that a checking is paid on time, wherein Yan Zheng step is that the requirement that is independent of operating unit is carried out.Verification step is described below.Receiving element is the access master station periodically, and with irrelevant to master station requirement information, and the receiving element unique identification sign indicating number that will be stored in the receiving element in the memory 119 is delivered to master station then.Memory 119 is a flash memory preferably.The identification code that the master station utilization is received attracts the search customer data base as gripping finger, and the result is delivered to receiving element.Make the identification code received still be proofing state not if do not find the identification code receive in customer data base, master station becomes also end verification step of broken string.When master station confirmed that identification code meets, the master station checking comprised the data, services expense of the data, services of last charges paid.When proving at the totally paid state, master station indication receiving element update service available life, authorization signal, and the time of the payment state of next time checking.Receiving element is responded, and is updated in data corresponding in the memory.So allow receiving element access master station to do the data requirement, till the service available life that upgrades expires.

Confirm but payment state when not verifying when the unique identification sign indicating number of receiving element is correct, in other words, find that promptly the information service expense do not pay on time, master station indication receiving element is updated to an of short duration service available life, and in interior next payment verification time of this of short duration service available life that upgrades.Master station is implemented same verification step in the access time of appointment.If customer data base does not have the indication that given information service expense correctly pays and upgrades, then master station is sent the service failure signal and is given receiving element.The methods availalbe that receiving element was lost efficacy is for example descrambling sound interval preface heavily to be changed and write in the descrambler 115.In addition, can not send the identification code of receiving element at receiving element paralysis period master station.In addition, by means of suitably upgrading descrambling sound interval preface and the initial date and time of update notifications program,, then have only the receiving element of on time paying the information service expense that the ability of the scramble of separating is arranged to avoid using without permission information service.

In this embodiment, so the access time of payment state checking is very important, so during each receiving element access master station, the internal clocking of receiving element need upgrade and revise the internal clocking to master station.Even the internal clocking of receiver has any mistake, because the correction of each access just can not be influential.This means work master station and whether does access according to arranging the time by means of the supervision receiving element and manage.Behind one section predetermined patient time that the intercropping access begins when receiving element does not have Yian row, master station is by means of service failure signal controlling receiving element.This skill is very useful for system carries out centralized management.
