When the user was inserted into the corresponding interface of computer with wireless data communication device of the present invention, data handling system recognized two communication ports when powering on, and it is carried out follow-up configuration as two Wireless Telecom Equipment M1 and M2; Operating system is sought device driver automatically, and microcontroller begins to carry out the solidification software that is solidificated in wherein immediately, comprises the steps:
A. microcontroller and peripheral interface chip thereof are carried out initialization;
B. operating system can be inquired about USB interface chip controls pipeline, and the USB interface chip can produce and interrupt giving microcontroller this moment, and microcontroller is got in touch by operation USB interface chip and operating system then.By a series of standard USB configuration, make that the whole drivers (Driver) that adapt to two Wireless Telecom Equipments that recognize respectively obtain loading;
C. carry out network and connect preparation, the controller module 17 of wireless data communication device of the present invention attempts to obtain the relevant information of wireless network user identification module 4, if the wireless network user identity identification information that reads is invalid, then stops subsequent network and connect preparation; If information is effective, then the broadcast singal that sends of search base station is determined carrier frequency, and frequency modulation also reads base station information, sets up network with the base station and is connected.

F. according to type, source and other information of operational order type and data message, operational order and data message are handled respectively, returned result.
G. quit work according to customer requirements or system's setting.
Because the wireless data communication device of present embodiment provides two communication ports, the data handling system end as two independently Wireless Telecom Equipment carry out work; And provide concatenation ability with public wireless network base station, so have lot of operation command and data message from data handling system, public wireless network base station, some can transmit these operational orders and data message by same communication port, and also some must transmit by the different communication passage.Communicate the selection and the combination of passage thus with regard to the radio data communication method that needs present embodiment, make synchronization, make full use of all communication ports as far as possible, handle when realizing multiple operation and data.
Now in conjunction with Fig. 3, in above-mentioned solidification software workflow, the f step of carrying out the concrete operations order further elaborates.
Simply, the wireless data communication device of present embodiment has from the data handling system termination type of doing order of bringing drill to an end: dial up on the telephone, call or send a fax, send this three class of note; And wireless data communication device is divided into the network information, short message, call and several classes of other system informations from the data message that wireless network base station receives.
According to the prior art of RFDC, dial up on the telephone and generally need take communication port for a long time, need to guarantee and public wireless network base station between continual exchanges data, also need continuous receive-transmit system information; And phone, fax and note belong to unexpected incidents, only take limited time and communication port.So present embodiment is arranged in a communication port with network operation, this two generic operations order of transmitting/receiving wireless network system information and data message and handles, and phone, fax and note are arranged in another communication port processing.Before concrete operations order or data message execution processing, judge the state of current communication port earlier, if communication port is taken by current operation, priority between then more current operation and the operation that will carry out, if current operator precedence level is high, then the operation that will carry out enters formation or storehouse waits; If the operator precedence level of carrying out is high, then current action need interrupts, and the preservation ephemeral data is gone forward side by side and waited into formation or storehouse, and current operation takies communication port and operates.The operational order that waits in formation or storehouse need wait communication port always and be released or take turns to when taking communication port, accesses this operational order again and handle from formation or storehouse.Described priority comparison mechanism and formation, storehouse mechanism can adopt existing multiple algorithm to realize in solidification software.
Specific practice is as follows:
When wireless data communication device when data handling system end or public wireless network receive operational order or data message, described wireless data communication device judges at first whether this operational order or data message effective, and whether form meets related standards; If invalid operation order or data message are then disregarded; If operational order or data message are that effectively then the content according to operational order or data message is divided into two generic operations with it:
One class is network operation or system operation class, and another kind of is phone, fax or note generic operation.
For network operation or system information class, the wireless data communication device controller is handled communication port R1 of specific assigned, and correspondingly data handling system also will be the independent Resources allocation of Wireless Telecom Equipment M1 of this communication port correspondence.Controller is obtained the exclusive right of this communication port, again operational order or data message is subdivided into the concrete operations type: dial up on the telephone, upload four classes such as data, data download and system operation, handle respectively.
For the operation of dialling up on the telephone, wireless data communication device calls the dial-up program in solidification software or the application software, and Outgoing Number is attempted network and connected, and may need the user to carry out authentication midway; If successful connection then begins the network data exchange, carry out concrete operations according to further operational order or data message, disconnect network or network connection interruption up to user command, then finish network and connect, preserve corresponding information.
The concrete operations that the user is undertaken by network be divided into upload, data download two classes.For uploading data operation commands, wireless data communication device is obtained the data that will upload from user's assigned address, and it is sent to the base station by network, return result;
For the data download operational order, wireless data communication device is obtained packet from wireless network, sends wherein data message to controller module, return result;
According to relevant agreement, wireless network base station continues transmitting system information, to keep being connected between wireless data communication device and base station, adjusts wireless data communication device.For this type systematic information, wireless data communication device keeps network to connect interim interrupt network exchanges data, calls controller module and/or radio receiving transmitting module and carries out operations such as system configuration and adjusting, keeps with the network of base station to be connected; Dispose in system information, after system operation finishes, proceed the network data exchange from interruptions again.。
It more than is processing method for network operation or system operation generic operation.Below will set forth the processing method of phone, fax or note generic operation.
Because phone, fax or note generic operation majority are operations of short duration, burst, there is no need to operate communication port of specific assigned separately for phone, fax or note, this three generic operation is with a shared communication port R2, and correspondingly data handling system also will be the Wireless Telecom Equipment M2 Resources allocation of this communication port correspondence.The swap data not mutually of this communication port and aforementioned M1 passage is handled respectively.
Because phone, fax or note generic operation is sudden, will produce conflict inevitably.Operation requests such as fax sending and receiving, transmitting-receiving note are for example arranged in communication process, situations such as call are perhaps arranged in sending the note process.For the operation requests that conflict is arranged, need in advance to each concrete operational order definition priority, according to override mechanism, give the high operational order of priority with the communication port priority allocation, treat its monopolize using after reallocation give priority time high operational order, up to handling all operations order.Unallocated operational order to the communication port resource need be waited for, enters usually in formation or the storehouse and waits for, up to the communication port free time, or takes turns to this operational order use communication port resource.
In the present embodiment, the priority of regulation Outgoing Call operation is the highest, is 5; Inbound Calls priority is taken second place, and is 4; Sending fax once more, is 3; The priority of receiving faxes is 2; Sending note priority is 1; And receive note priority minimum is 0.And because short message/fax general data amount is less, transmitting-receiving time weak point need not interrupt, and voice call generally is continuous, can not interrupt; In case so regulation note/facsimile data begins Network Transmission and just can not interrupt, the operation that priority is high must wait for that also one group of data transmit-receive finishes or fails, communication port carries out the priority ruling again during the free time.
If the primary network unsuccessful transmission, regulation note/facsimile data can carry out the repeated attempt of limited number of times, up to transmission success or failure.Between twice trial, can be according to the transmitting-receiving operation of priority ruling consequent interruption note/fax.This priority prescriptive procedure is only made example, does not constitute the qualification to invention essence.
Under the regular situation, each concrete operations is normal respectively to be carried out, and calls override mechanism and carry out ruling under a plurality of operational order conflict situations.
Specifically, for Outgoing Call or send the operational order of fax, wireless data communication device calls dial-up program, and Outgoing Number is attempted connecting, if the other side's call accepted, the exchange of lang sound data or facsimile data of going forward side by side then connects; Finish up to end of conversation or facsimile transmission, disconnect network again and connect; If the other side's call not accepted or just the line is busy then stops dialing, return failure information.
Call out as external voice and to enter wireless data communication device, or when having fax to receive, wireless data communication device judges whether communication port is occupied, and promptly whether the line is busy earlier; If unoccupied, the communication port free time then wireless data communication device indicate call establishment according to the user, carry out the exchange of speech data or facsimile data, until data exchanging completed, wireless data communication device disconnects network and connects; If the line is busy or the user disconnects calling for communication port, then this external call operation should be postponed execution, so send for information about to the other side, the other side will stop call.
Need utilize wireless data communication device to send under the situation of note the user, whether wireless data communication device also needs to detect communication port earlier idle, if passage is occupied, then according to the override mechanism ruling, this transmission note operation enters formation and waits for.Be released up to communication port, send the note operation again, set up network and connect, note is sent in trial, if send failure owing to network failure or information are wrong, then repeats limited number of time and attempts, finish or fail up to transmission, return information also disconnects network and connects.If between the process of repeatedly attempting the transmission short message, there is the operational order of conversation or fax sending and receiving to produce, then according to the regulation of override mechanism, send the note operational priority and be lower than voice, fax operation, so attempt operation disruption, the record interrupt status discharges communication port laggardly to go into formation and wait, wireless data communication device is distributed to the high voice of priority, the use of fax operational order with communication port, up to finishing using, access again again and send note trial operation, continue to carry out.
For receiving the note operation, principle is similar with the transmission note, if communication port takies, then according to the override mechanism ruling, enters formation and waits for the communication port free time, sets up network again and connects, and receives data.May receive the note operation according to priority mechanism during the transmission of not carrying out note data will interrupt, and communication port is sold to the high operational order of priority.
Certainly, the present invention can not come the allocate communications passage according to the concrete operations type yet, but carries out flexible allocation according to user concrete operating position or data volume size.For example, according to the concrete operating position of user, need frequent fax sending and receiving, then wireless data communication device is not provided with certain generic operation order and monopolizes certain communication port, but when facsimile data need exchange, uses a communication port; If simultaneously other operational orders are arranged, then use another communication port to carry out; If two passages have the facsimile data operational order when all occupied, then from two operations using communication port, select an operation that priority is lower or holding time is short, with its interruption or its data exchanging completed of of short duration wait, the communication port resource is discharged, distribute to fax and manipulate.In addition,, utilize two passages to transmit simultaneously, by receiving terminal the data that two communication ports transmit are respectively integrated again if certain action need transferring large number of data also can split described mass data.Distribution mechanism to communication port is not unique.
The present invention can adopt USB interface link to each other with data handling system, hot-swappable, merge USB, mobile storage technology and mobile communication technology, the directly communication service of using mobile telephone company to provide, can realize the transfer of data between mobile phone, the computer, excellent reliable mobile storage and performance for wireless communications and wireless networking capabilities are provided, can receive and send wireless data information, comprise voice, data, short message, control information etc.Apparatus of the present invention can make computer become the public wireless network terminal of internet.
