The embodiment of the invention is as described below.
Two kinds of processing modes are adopted in order for OTA.A kind of processing mode is handled for adopting the OTA kit to use, as shown in Figure 3.
In the JAVA module, realize an OTA Toolkit Applet (application of OTA kit).With the application of OTA Toolkit Applet as the JAVA module, OTA Toolkit Applet realizes download and the bytecode parsing that OTA uses.By the application of IC cards of JAVA module, for example (U) SIMApplet receives OTA message.
Because the usim card sheet is the 2G/3G composite card, 2G APDU order is used by SIM and is handled; 3G APDU order is used by USIM and is handled.The OTA order is the order of OTA technical protocol definition; The OTA order data carries out the protocol message encapsulation of OTA agreement, and the protocol data that comprises the OTA order after the encapsulation sends to the usim card sheet as the content of envelope command by envelope command.Envelope command is a kind of APDU order.
(U) SIM Applet judges when OTA orders corresponding OTA Toolkit Applet, OTA message is transferred to JAVA CAT RE handle, and JAVA CAT RE triggers OTA Toolkit Applet and handles.
Another kind of processing mode is handled for adopting the OTA virtual machine, as shown in Figure 4.The OTA virtual machine comprises OTA interface module and OTA processing module.
(U) SIM Applet in the JAVA module handles all 2G/3G APDU orders.(U) SIMApplet judges when OTA orders corresponding traditional OTA to use, and gives OTA virtual machine with OTA message.
The OTA processing module realizes in localized mode.The localization mode is meant that the OTA processing module realizes in non-JAVA mode, and the OTA processing module is as the module of an independent realization OTA function.
Adopt this dual mode can carry out the differentiating and processing of Java message and traditional OTA message:
The usim card communication module receives OTA message, sends to the Java module.For ENVELOPE order (envelope command) in the OTA message, (U) SIM Applet analyzes the TAR value in the wherein OTA order, distributes according to the TAR value, and concrete rule is as follows.
If the TAR value is 0xB00010 or 0xB0001F, then is distributed to the OTA virtual machine and handles; If the TAR value is other values, then is distributed to Java CAT RE operation OTA Toolkit Applet and handles.
For traditional OTA used, the TAR value represented that for 0xB00010 OTA orders corresponding common OTA to use in this OTA message, and the TAR value is represented the remote document management (RFM) that OTA orders corresponding OTA in this OTA message for 0xB00001F.
If OTA orders corresponding OTA kit to be used, then use by the Java CAT RE operation OTA kit of Java module, if OTA orders corresponding traditional OTA to use, give OTA virtual machine with OTA message, handle by standard by the OTA virtual machine.
Those skilled in the art can also carry out various modifications to above content under the condition that does not break away from the definite the spirit and scope of the present invention of claims.Therefore scope of the present invention is not limited in above explanation, but determine by the scope of claims.
