Description
The present invention relates to be used for the method and apparatus of receiving selective paging signal, particularly relate to the selective paging signal receiving system that can receive such paging signal, be that a plurality of signals are in the transmission code system that the transmitter of mobile communication system is predesignated, for example in the selective paging signal system, sent continuously and repeatedly, be the invention still further relates to the method that is used to receive this selective paging signal.
The selective paging signal system be by will be used to notify first yard of transmitting and a sequence a plurality of yards of designated form be connected and arrange.The sign indicating number sequence of designated form is by constituting with receiving system synchronous second yard, the trigram that comprises address code, message information and check code.
Fig. 2 A represents this signal system.A kind of typical signal system is so-called " POCSAG (Post Office Standardization Advisory Group, postcode standardization guidance group) " signal system.
For saving battery power consumption, the receiving system that uses the POCSAG signal system is to be interrupted the working method received signal.Therefore many economize on electricity designs have been proposed.
Fig. 2 represents to wait for first yard state and the operation that detects after first yard.The operation of the receiving system that one of the TOHKEMY application No.63-13432 (see figure 3) of Fig. 2 (a) and Fig. 2 (b) expression and prior art and embodiment (see figure 5) is corresponding.The operation of introducing these prior aries is operation of the present invention for convenience of explanation.Fig. 4 is the schematic block diagram of prior art receiving system operation scheme shown in Fig. 2 (b).
To be described in detail Fig. 2 now.According to the method for Fig. 2 (a),, connect receiving circuit so that carry out the operation that detects preamble (preamble) (first yard) whenever through preselected time week after date.When detecting preamble (), this operation progress is to the detecting operation of synchronous code SC (second yard).After this, when detecting synchronous code SC, setting up should be synchronously.Synchronously operation progress is arrived the detecting operation (4) of subsequent synchronisation sign indicating number SC according to this, and paging code (trigram) detecting operation (3).Yet, as what offer some clarification in the special permission openly of above-mentioned Japan, when a sequence signal group transmission is finished, when another sequence signal group has just arrived, this conventional system has the shortcoming that can not catch these new arriving signal groups, along with finishing by the signal that interrupts Fig. 2 (a), when one or many fails to detect synchronous code, this operation proceeds to the intermittent operation that detects preamble (see top, the 2nd page of hurdle, bottom right of TOHKEMY application No.63-13432, and with reference to figure 3 (a) " X ") once more.In Fig. 2 (b), in each timing that receives synchronous code, set the time of catching preamble.
According to the method for Fig. 2 (b), omitted the detecting operation of synchronous code SC, and adopted the periodicity of paging code to judge synchronous regime.Compare with the method for Fig. 2 (a), the method for Fig. 2 (b) can improve the effect of saving battery supply.In addition, between two continuous paging codes, provide the detecting operation of preamble again, so that detect the arrival of new preamble.
When according to this operation, detect preamble () and when detecting synchronous code SC (0) thereafter, from this constantly this operation progress to the detecting operation (3) of paging code.Next, carry out the detecting operation (3 ') of next paging code as synchronous code with this paging code.
Fig. 4 illustrates the electric wiring plan with the above-mentioned receiving system of the regulation work of Fig. 2 (b).Be received device 21 demodulation from the reception data of antenna input, and restituted signal is delivered to decoder 22.In decoder, from demodulating data, discern and detect first to trigram according to the application drawing of Fig. 2 (b).These testing results are offered timing controller, according to predetermined timer value on/off switch S1 and S2, so that receive operation.
According to above-mentioned conventional method (a), its main purpose is to save the battery supply aspect, does not finish a sequence signal group any inventive concept afterwards and lie in.In conventional method (b), in the reception regularly of synchronous code, carry out the preamble detecting operation again, and in receiving system, adopt specific turn-on time.For emphasizing to save battery supply, fully select the turn-on time minimum value so that catch this preamble.
As mentioned above, the main purpose of prior art systems is to reduce consumption of cell power supply as far as possible.When causing a sequence signal group transmission operation disruption owing to the appearance interference, stop signal receives.Wait for that sending preamble (first yard) thereafter reads information afterwards once more again.Otherwise, the operation of inserting the high shock capturing preamble signal.Reducing this signal capture time as much as possible reduces with the saving efficient that prevents battery supply.
An object of the present invention is to provide a kind of simple signal acceptance method and the low-cost receiving system of making, even also can return to the signal accepting state rapidly, and when disappearing, this disturbance state keeps suppressing the function of consumption of cell power supply when the signal reception period temporarily comes across the situation of disturbing.
Another object of the present invention provides the method for reseptance of sort signal and device, and it can detect synchronous code and preamble simultaneously, even so that when a sequence data group arrives again, can receive this data set immediately.
Be noted that " disturbance state " mentioned is meant the state that can not receive that is caused by underlying cause in specification.That is, when receiving system when signal propagation direction enters a tunnel or pile regional, or when very sending signal near the place of this signal receiving device this disturbed condition will appear when a high power transmission receiver.

In order to understand the present invention better, in conjunction with the accompanying drawings the present invention is made detailed description.
Fig. 1 is the circuit diagram according to the receiving system of the embodiment of the invention;
Fig. 2 illustrates that compared with prior art the signal of receiving system shown in Figure 1 receives the schematic diagram of operation;
Fig. 3 illustrates that compared with prior art the signal of receiving system shown in Figure 1 when disturbed condition occurring receives the schematic diagram of operation;
Fig. 4 is the circuit diagram of receiving system commonly used.
Fig. 1 is the electric wiring plan that the present invention is applied to the signal receiving device of working in the POCSAG signal system.Fig. 2 is the conventional reception operation (a) of illustrative ground expression and (b), and (c) operated in reception of the present invention.The routine of Fig. 3 illustrative ground expression when occurring disturbed condition takes place receives operation (a) and (b), and (c) operated in reception of the present invention.Fig. 3 has clearly reflected feature of the present invention.
As previously mentioned, POCSAG signal is to be positioned at the preamble (first yard) of stem and then batch (batch) subsequence more than of this preamble (the seeing Fig. 2 A) formed by one.This bulk information is by the sequence arrangement of a synchronous code SC (second yard) and a paging code (pagingcode) (the 3rd).In this example, a bulk information constitutes (time limit that equals synchronous code) by 544 bits.Synchronous code SC is by 32 bit arrangement, and then the paging code of this synchronous code SC is made of 32 bits equally.This paging code is assigned in 224 bit to 287 bits that this end of Secondary Synchronization Code rises.
Among Fig. 1, label 1 expression is used to receive the antenna of POCSAG signal, label 2 expression receiving circuits (being equivalent to receiving system).The signal that is received by this receiving circuit 2 is sent to a preamble testing circuit (being equivalent to first yard checkout gear), 4 and paging code testing circuits (being equivalent to the trigram testing circuit) 5 of a Sync (synchronously) sign indicating number testing circuit (being equivalent to second yard testing circuit).
First timing generation circuit of second yard detection circuit operation duration task of definition is born in label 7 expressions, and produces the timing signal that is equivalent to the synchronous code time remaining cycle.In this case, because the length of synchronous code is 32 bits, first timing generation circuit 7 is used to count the such timing signal of 0 to 31 bit (32 bit) according to the output generation that receives from counting circuit 6.This output will constitute the ON signal (connection signal) of switching circuit 9 and be sent to second yard testing circuit 4.
Second timing generation circuit (device) of the operation cycle task of definition paging code testing circuit 5 is born in label 8 expressions.This output cycle is the such time cycle that defines after the synchronous code by detecting, and detects the position of distributing to paging code.
In this case, this output cycle was equivalent to detect after the synchronous code by the 224th bit to the 287 bits (64 bit period) the official hour cycle.When Secondary Synchronization Code testing circuit 4 received output instruction signal, this output became ON (connection) signal of switching circuit 9, and delivers to paging code testing circuit 5.When receiving the output stop signal, do not produce output signal.Therefore, do not provide ON (connection) signal, and receiving circuit 2 and paging code testing circuit 5 are not worked to switching circuit 9.Label 9 is the switching circuits that are used for only connecting the working power 10 of receiving circuit 2 during the output cycle of first timing generation circuit 7 and second timing generation circuit 8.Label 11 expressions are used to show that the warning (alert) of the information that is detected by paging code testing circuit 5 produces circuit (display unit), and this alarm generation circuit can be made of a loud speaker, a buzzer or a LCD.
According to operation chart shown in Figure 2, operation according to the receiving system of the embodiment of the invention is described in the mode that is compared with the prior art.
Fig. 2 (a) is the prior art of describing among the Japanese laid-open patent application No.63-13432, and Fig. 2 (b) is corresponding to one of embodiment that describes among the Japanese laid-open patent application No.63-13432, and Fig. 2 (c) represents the present invention.
In this operation chart, the preamble when symbol " x " expression fails to detect synchronous code, or constantly.Symbol " 0 " expression is when the moment that can set up when synchronous.Moment when symbol " " expression detects preamble.Symbol (1) expression receiving circuit is interrupted the time cycle of duration of work so that detect this preamble.Symbol (2) expression detects after the preamble, the time cycle during detecting synchronous code the power supply of receiving circuit being switched on simultaneously.This time cycle is set to and slightly is longer than preamble length and synchronous code length.Symbol (3) expression detects after the synchronous code, the time cycle during the detection paging code.Symbol (3 ') expression detects after the paging code, detects the time cycle during the next paging code.Symbol (4) expression is found after the synchronous code, the time cycle during the detection subsequent synchronisation sign indicating number.In addition, the time cycle during symbol (4 ') expression further the carrying out preamble detecting operation.
Under the situation that no POCSAG signal sends, as shown in (1), the prior art among Fig. 2 (a), Fig. 2 (b) and the present invention of Fig. 2 (c) have identical meanings.That is, whenever lasting a fixed time period, this receiving circuit is connected discontinuously, carries out preamble and waits for operation.Yet, in Fig. 2 (b), as previously mentioned, omitted synchronous code SC detecting operation, utilize the periodicity of paging code to judge synchronous regime.Detect this preamble by the preamble detecting operation that between two continuous paging codes, additionally provides.Therefore, in the search preamble, receiving system is also carried out the synchronous regime detecting operation.
As previously mentioned, this counting circuit is to be set to output has the identical time limit sync (synchronously) signal of (i.e. 544 bit durations) with synchronous code circuit.When receiving this synchronizing signal, 7 work of first timing generation circuit, the output signal of this first timing generation circuit 7 (has the pulse signal with the synchronous code equal length, 0 to 31 bit duration) is provided for switching circuit 9, receiving circuit 2 can be operated during 0 bit to 31 bit time periods by switching circuit 9.The output signal that receiving circuit 2 is produced offers first yard testing circuit 3 waiting for that preamble arrives.Output signal from first timing generation circuit 7 also is input to second yard testing circuit.This second yard testing circuit be at the timing working identical with first yard testing circuit 7, and carry out the detecting operation of synchronous code simultaneously.
When first yard testing circuit 3 found preamble, this first yard testing circuit 3 sent a reset signal to counting circuit 6, so that this counting circuit 6 resets.Then, respond this setting counting circuit 6 and produce output, 7 work of first timing generation circuit are to produce timing signal.Switching circuit 9, preamble testing circuit 3 and synchronous code testing circuit 4 these timing signals of response are started working.Then, repeat this operation and detect this synchronous code (symbol ) up to synchronous code testing circuit 4.
When synchronous code testing circuit 4 detected synchronous code (symbol 0), the command signal of output was admitted to second timing generation circuit 8.As previously mentioned, the synchronous signal of counting output value of second timing generation circuit 8 generation time cycles (from the time cycle of 224 bit to 287 bits) and counting circuit 6.This time cycle is finished up to the discovery paging code by the synchronous code detecting operation and stipulates.When receiving the output instruction signal that Secondary Synchronization Code testing circuit 4 sends, second timing generation circuit 8 produces timing signals.This output timing signal is imported into switching circuit 9 and paging code testing circuit 5, so that receiving circuit 2 and paging code testing circuit 5 enter operating state.Therefore, when receiving transmission signals, receiving circuit 2 offers paging code testing circuit 5 with the signal that is received.When paging code testing circuit 5 is found (own) paging code intrinsic in this time cycle, produce alarm signal, so that make 11 work of alarm signal generation circuit.Be noted that Secondary Synchronization Code detected during cycle a period of time of the time cycle that is assigned with (0 to 223 bit), and behind the paging code end cycle, second timing generation circuit 8 does not produce timing signal.
In addition, owing to arrive the time cycle (554 bit) of next synchronous code, counting circuit 6 output synchronizing signals.First timing generation circuit 7 is exported timing signal during the time limit corresponding to duration of synchronous code.Next, when detecting synchronous code, repeat aforesaid operations.
On the other hand, in Fig. 2 (a), when detecting synchronous code, regularly proceed the detecting operation of paging code (3) and next synchronous code (4) according to this detection.In Fig. 2 (b), detect synchronous code.In addition, when detecting synchronous code (3), the detecting operation of cancellation synchronous code and only proceed the detecting operation (3 ') of paging code.In view of having stopped the synchronous code detecting operation, so this operation can realize saving battery power consumption.Be noted that the preamble detecting operation is inserted in the middle of two paging codes.
With reference now to Fig. 3,, the present invention (c) is contrasted the operation when being described in signal reception and the temporary transient intercourse appearance of signal reception quilt generation interference with the prior art (a) and (b).
Usually, in the POCSAG signal system,, do not send the sign indicating number that the transmission of expression signal is finished even when sending a sequence signal.Therefore, shown in Fig. 3 (a), when detecting synchronous code, or during paging code, do not detect preamble (x), so that when the signal transmission is interrupted, can't judge, still finished transmission owing to a sequence signal owing to occurred disturbing this signal transmission is interrupted.Therefore, if synchronous regime keeps the long period, when then existing the signal that formerly sends when a sequence to finish, can not receive the shortcoming of a sequence New Development feed signals.Therefore, mode of operation proceeds to asynchronous mode, just restarts the preamble detecting operation later in this transition.Among Fig. 3 (b), the duration of detecting preamble is limited to minimum value, so that solve this defective, and makes detector in the timing place interruption work identical with synchronous code.
According to the present invention, when second yard testing circuit 4 of signal reception period can not detect synchronous code, this second yard testing circuit 4 carried the output stop signal to second timing generation circuit 8, so that do not export second timing signal.The result is that receiving circuit 2 and paging code testing circuit 5 are in off position.Yet, there is not adverse effect in the counting operation of counting circuit 6, when keeping synchronous regime, its operation is proceeded.Therefore, by the count output signal that receives from counting circuit 6 first timing generation circuit 7 is worked on, so that receiving circuit 2, preamble testing circuit 3 and synchronous code testing circuit 4 are also worked.The result is, under condition of acceptance, keep synchronous regime with transmission signals in, the receiving system of the present invention arrival of new preamble that can make an immediate response, and can from the interference of follow-up appearance, recovering rapidly.
In Fig. 3 (a), when failing to detect synchronous code (x), then carry out the synchronous code detecting operation once more.Even can not detect synchronous code (follow-up x), then suppose the end of transmission of a sequence signal, so reenter the preamble detecting operation.Among Fig. 3 (b), when failing to detect paging code (x), if disturbance state is resumed, receiving system is the entering signal accepting state once more.Because the preamble detecting operation is inserted in the middle of the continuous paging code, can begin the preamble detecting operation immediately under the situation of the signal end of transmission.
Be noted that after detecting synchronizing signal, this detecting operation stops owing to emphasizing to save the battery power consumption operation among Fig. 3 (b), the timing that utilizes this paging code is as synchronizing signal.As a result, be still when receiving system enters preamble detecting operation state, this receiving system keeps a kind of like this synchronous regime, and promptly this paging code is used as the timing except that the preamble detecting operation.Therefore, when finding preamble, can not carry out the operation of the saving battery power consumption of similar Fig. 3 (a) effectively.
Otherwise, according to the present invention, because the count output signal of the counting circuit (synchronization signal generation apparatus) 6 that resets from preamble testing circuit 3 is often used as the reference time signal that offers first timing generation circuit 7 and second timing generation circuit 8, therefore can be with the circuit arrangement of simple and this receiving system of low-cost production.In addition, this receiving system can recover back response synchronous regime from occurring interfering with, and also can respond the synchronous regime that resends signal.When searching preamble, can realize being similar to the operation of the saving battery power consumption of Fig. 3 (a).
Because the amount of information that is sent out is increased recently, the information in enormous quantities of this preamble will be connect after adopting.The result is that the transmission time that sends a sequence signal is extended, and exists because the trend of disturbing the number of times when causing the signal transmission to interrupt to increase.In addition, be starved of the manufacturing cost that reduces receiving system.As previously mentioned, it has realized method of reseptance and receiving system cheaply according to the present invention, and temporary transient interference that can make an immediate response, and finishes the signal transmission when keeping power saving function.
According to the present invention, second yard detecting operation and first yard detecting operation carry out simultaneously.The synchronizing signal of exporting from the synchronization signal generation apparatus that presets when detecting first yard is often used as the reference time signal of second yard detecting operation and trigram detecting operation.Therefore, when reserve section was economized battery energy consumption function, it can be with simple and this receiving system of low-cost production.Even when signal receives temporary transient the interruption, because being received operation, normal signal do not have adverse effect, if can recover communications status, then can proceed signal immediately and receive, so that this receiving system can respond the interference of appearance effectively.In addition, even when because sequence signal transmission is finished during the interrupt signal transmission, if arrive a sequence signal group again, this receiving system can be immediately and is advantageously responded newly arrived signal.
