Embodiment
The present invention realizes the method being applicable to the USB equipment complex of Large Copacity USIM, and it uses and comprises main frame and Large Copacity usim card.Main frame adopts mobile phone terminal or working computer, and Large Copacity usim card is the USB device comprising a configuration, two interfaces, four communication end points, and two interfaces are CCID agreement and Mass Storage agreement respectively.
Referring to Fig. 1, after the Host Detection such as mobile phone terminal or working computer connects to Large Copacity usim card, main frame sends the request obtaining descriptor to Large Copacity usim card, Large Copacity usim card carries out the reply responded, and concrete data exchange process is as follows:
1) host requests is to the request of Large Copacity usim card transmitting apparatus descriptor;
2) Large Copacity usim card responds this request, reverting equipment descriptor information, and instruction Large Copacity usim card has a configuration, and annunciator community string index community number (Index=1);
3) main frame sends the request of configuration descriptor to Large Copacity usim card;
4) Large Copacity usim card responds this request, replys configuration descriptor information, and instruction Large Copacity usim card has two interfaces; Large Copacity usim card sends first interface descriptor information, indicates this interface to be CCID communications protocol interface, employs two end points, and informs this interface character string indexing number (Index=2); Large Copacity usim card sends the endpoint descriptor information of two end points that CCID interface is used, the direction of communication of instruction end points and data transmission capabilities; Large Copacity usim card sends second interface descriptor information, indicates this interface to be Mass Storage communications protocol interface, to employ two end points, and informs this interface character string indexing number (Index=3); Large Copacity usim card sends the endpoint descriptor information of two end points that Mass Storage interface is used, the direction of communication of instruction end points and data transmission capabilities;
5) host requests Large Copacity usim card equipment character string descriptor (Index=1);
6) Large Copacity usim card responds this request, reverting equipment character string descriptor information;
7) the CCID interface character string descriptor (Index=2) of host requests Large Copacity usim card;
8) Large Copacity usim card responds this request, reverting equipment character string descriptor information;
9) Mass Storage interface character string descriptor (Index=3) of host requests Large Copacity usim card;
10) Large Copacity usim card responds this request, reverting equipment character string descriptor information.
Descriptor is obtained at the main frame such as mobile phone terminal or working computer, and identify that Large Copacity USIM is after the equipment complex of multiplex roles, main frame sends the order of corresponding agreement on the end points that CCID and Mass Storage two interfaces are corresponding, realizes the data interaction of distinct interface, different application.Because two interfaces and the end points used are independently, so when two interfaces work simultaneously, the communication of CCID and Mass Storage does not affect mutually, each interface receives order according to corresponding communications protocol, the order of Large Copacity USIM to each interface processes, and replys over that interface.
As shown in Figure 2.Data interactive method step is:
1) Host Detection is the equipment complex of two interfaces to Large Copacity usim card, sends APDU order and data by the end points of CCID interface to it;
2) Large Copacity usim card is by the end points response APDU order of CCID interface;
3) main frame sends memory access command and data by the end points of Mass Storage interface to Large Copacity usim card;
4) Large Copacity usim card is by the end points response visit order of Mass Storage interface.
When two interfaces work simultaneously time, main frame alternately can send CCID order and Mass Storage order, and the order that so just there will be an interface processes, and the situation that the communication of another interface starts.
As shown in Figure 3.In order to ensure the conventional telecommunications business that priority is higher, first Large Copacity USIM, once have received a new CCID order, even if now processing Mass Storage order, is also processing the CCID order received, and respond in time, continue again afterwards to process the operation do not completed.Collaborative work command handling method step is:
1) main frame sends memory access command and data by the end points of Mass Storage interface to Large Copacity usim card, sends APDU order and data by the end points of CCID interface simultaneously;
2) Large Copacity usim card is by the end points response visit order of Mass Storage interface, simultaneously by the end points response APDU order of CCID interface.
The cognitive phase of the USB equipment complex of Large Copacity USIM is applicable in implementation method of the present invention, after Large Copacity usim card is connected with the main frame such as mobile phone terminal or working computer, main frame starts to send request multiple descriptor request to Large Copacity usim card, comprise device descriptor, configuration descriptor, interface descriptor, endpoint descriptor, character string descriptor, Large Copacity usim card, by replying corresponding information to main frame, informs the device type of Large Copacity usim card, interface type, end points service condition and other information.
The data communication stage of the USB equipment complex of Large Copacity USIM is applicable in implementation method of the present invention, by obtaining multiple descriptor at the main frame such as mobile phone terminal or working computer, identify that Large Copacity usim card is after the equipment complex of multiplex roles, main frame carries out data interaction communication respectively on CCID and Mass Storage two interfaces.Communication and the process of two interfaces are all independently, so when two interface collaborative works, the communication of CCID and Mass Storage does not affect mutually, each interface receives order according to corresponding communications protocol, the order of Large Copacity usim card to each interface processes, and replys over that interface.
The collaborative work situation in the data communication stage of the USB equipment complex of Large Copacity USIM is applicable in implementation method of the present invention, be the main frame such as mobile phone terminal or working computer carries out conventional telecommunications newsletter and mass memory communication simultaneously situation to Large Copacity usim card, CCID order and the Mass Storage order of now main frame transmission can alternately take usb data bus.In this case, once have received a new CCID order, the CCID order that Large Copacity usim card priority processing receives, and respond in time, even if now processing Mass Storage order, after the reply completing CCID order, then continue to process the operation do not completed.
