When expansion module 3 is connected by described communication bus interface with main frame 1, the application of carrying out expansion module 3 by flow process as shown in Figure 4 be connected: may further comprise the steps:
S10: expansion module inserts, to the connection application information of main frame transmission;
S20: main frame receives the application information that expansion module sends, and according to application information, determines the communication pattern with expansion module, between connect.
Specifically, the detection of expansion module signal and setting, concrete detailed process may further comprise the steps as shown in Figure 5:
S101: expansion module inserts;
S102: expansion module detects main frame RDY, if RDY is low, then not start of main frame can't connect;
S103: if the RDY height, then main frame start, it is low that expansion module is established RDY;
S104: main frame detects the insertion of expansion module, by main communication pin, and expansion module or the main frame language that rises, both sides set up soft shaking hands;
S105: expansion module is to the pattern of main frame application from the communication pin, because expansion module difference, so the communication pattern that requires also might be different, so application information according to expansion module, main frame is provided with the pattern of each communication pin, this pattern can comprise: analog form, I2C, SPI isotype.
By above step, set expansion module and main frame from communication pattern, both sides set up the connection of physical signalling layer.
The WPnP data link layer is used for guaranteeing that data transmit accurately between main frame and expansion module.Data link layer in the position of WPnP protocol stack as shown in Figure 6, the WPnP data link layer is followed the industry member standard of general serial communication protocol basically.But the different main frames of WPnP and the ability to communicate of different expansion modules, computing power and memory size have very big difference again, the WPnP data link layer can have the ability to consult the function that adapts to flow, so after the connection of both sides' physical signalling layer is set up, carry out method that capability negotiation and flow adapt between expansion module and the main frame as shown in Figure 7, may further comprise the steps:
S30: expansion module is consulted application to the main frame transmittability, and wherein negotiate content can comprise the size of transmits data packets, the size of data buffer, the method for data integrity check, and/or the parameter setting from communicating by letter;
S31: main frame receives this application, according to the transmission of the content control data of application, and returns confirmation to expansion module.
Illustrate, because the data transmission capabilities of the expansion module that has is low than the transmittability of main frame, so in the process of above capability negotiation, capabilities setting according to main frame and expansion module, can negotiate the transmission of asymmetric uplink and downlink packet as shown in Figure 8: promptly: main frame is big to the expansion module data packets for transmission, and expansion module is little to the main frame data packets for transmission, and the result of negotiation is optimized both data transmission capabilities.
Because expansion module of the present invention may be diversified, such as being the another kind of wireless terminal module different with main frame, it also may be magnetic stripe reader, or barcode scanner, or smart card reader or the like, so require main frame to be provided with the application corresponding agreement, as: the telephone type agreement, the magnetic stripe reader quasi-protocol, scanner quasi-protocol, smart card quasi-protocol.So require on main frame, to be provided with and the expansion module corresponding protocol of inserting, therefore, carry out the management of expansion module agreement according to flow process as shown in Figure 9, step is as follows:
S21: expansion module sends the category IDs application of this module to main frame;
S22: main frame receives the category IDs application of expansion module, judges whether main frame has this quasi-protocol;
S23: if this quasi-protocol is arranged, then main frame sends the already present message of this quasi-protocol to expansion module, turns to the S27 step;
S24: if this quasi-protocol not, then main frame sends the not message of this quasi-protocol to expansion module; Expansion module sends the URL address that can download this agreement to main frame;
S25: the URL address that main frame sends according to expansion module, send the download application to the OTA Download Server, begin to download this agreement after meeting with a response, this download can be that J2ME downloads or local the download;
S26: after agreement was downloaded, main frame was installed this agreement automatically, and sent the message that agreement exists to expansion module;
S27: expansion module sends the message of service beginning to main frame.
Through above process, no matter on main frame, add any expansion module, all can download related protocol automatically, make the expansion module can proper communication.
If on expansion module, there is not the expansion module quasi-protocol of relevant expansion module, can send the application of this quasi-protocol of request to main frame, after main frame receives, flow process according to Fig. 9 is downloaded related protocol by main frame, by main frame the agreement of downloading is sent to expansion module again, expansion module receives this agreement, installs automatically, certainly, also can answer requirement of client to carry out the unloading of agreement.
Equally, the application program of different expansion modules is also inequality, also can be about to agreement and be replaced by application program by carrying out the download and the installation of application program with the similar process of above flow process.
It is the method for download service agreement and application that Figure 10 illustrates module promptly slotting.Figure 11 illustrates the structure of WPnP protocol layer.
Above method is to realize by hardware or software and hardware phase structure.
So, according to one embodiment of the present of invention, the wireless terminal that the plug and play expansion module is set of the present invention as shown in figure 12, is provided with main frame 1, expansion module 3, communication bus interface 2a is set on the main frame 1, communication bus interface 2b also correspondingly is set on expansion module 3, above-mentioned two communication bus interface 2a, 2b can be connected by Bussing connector 4, also can directly peg graft.When expansion module 3 is connected with main frame 1, expansion module 3 powers on, and the transmitting element 310 in the expansion module 3 sends application information to main frame 1, after the receiving element 110 in the main frame 1 receives this application information, by unit 120 is set, the communication pattern with expansion module is provided with; Then, transmitting element 310 in the expansion module 3 sends the category IDs application of this module to main frame 1, after receiving element 110 in the main frame 1 receives this application information, whether have the agreement and/or the application program of such expansion module by judging unit 130 main frames, if have, just send confirmation to expansion module,, send the information of this quasi-protocol not and/or application program to expansion module by transmitting element 140 if do not have by transmitting element 140; After receiving element 320 in the expansion module 3 receives above-mentioned information, if there is not the information of agreement and/or application program, then send the URL address that to download this agreement and/or application program by transmitting element 310, the URL address that main frame sends according to expansion module, cross transmitting element 140 and send the download application to the OTA Download Server, begin to download this agreement and/or application program by receiving element 110 after meeting with a response, this agreement and/or application program are downloaded to storage unit 160, after agreement and/or application program are downloaded, main frame automatically performs the installation of this agreement and/or application program by installation unit 170, and sends the message of agreement and/or application program existence to expansion module by transmitting element 140.
