Example Embodiment

[0030] The present invention encapsulates the interface units of the GRRC module, the URRC module and the MM module together to become an independent adaptation device, provides interface encapsulation for the message interaction of the above three modules, realizes the unity of management, and facilitates later maintenance.
[0031] Reference figure 2 , The method for dual-mode switching of a mobile terminal of the present invention is proposed, including:
[0032] Step 101: After receiving the handover command of the first RRC module, forward it to the MM module and the second RRC module;
[0033] Step 102: Complete the message exchange between the first RRC module, the MM module, and the second RRC module, so as to realize the mode switching of the MM module and the second RRC module.
[0034] The above-mentioned first RRC module is a GRRC module, and the second RRC module is a URRC module, or the first RRC module is a URRC module and the second RRC module is a GRRC module.
[0035] The above-mentioned mode switching is switching from GSM mode to UTRAN mode or switching from UTRAN mode to GSM mode.
[0036] Reference image 3 Taking the switching from GSM mode to UTRAN mode as an example, the working principle of the dual-mode switching method for a mobile terminal of the present invention is explained.
[0037] The physical layer of the mobile terminal receives the handover command from the network and forwards it to the data link layer;
[0038] After data unpacking, the data link layer transmits the complete switching command to the GRRC module;
[0039] The GRRC module parses the message and sends a handover notification to the adaptation device;
[0040] The adaptation device forwards the switching command to the MM module;
[0041] The GRRC module sends a request to suspend the current main signaling connection to the data link layer;
[0042] After the GRRC module receives the suspend response message returned by the data link layer, it sends a handover start request to the URRC module through the adaptation device;
[0043] The adaptation device requests the physical layer to deactivate the current GSM network resources;
[0044] After receiving the confirmation of deactivation resources sent back by the physical layer, the adaptation device sends a handover request to the URRC module of the URRC network;
[0045] The URRC module sends a notification of successful switching to the adaptor. After that, the adaptation device notifies the GRRC module that it has successfully switched to the URRC network;
[0046] The GRRC module sends the release of the old GSM network resources to the data link layer, and after receiving the confirmation of the completion of the link release from the data link layer, informs the adaptation device that the handover from the GRRC network to the URRC network has been successfully completed;
[0047] The adaptation device sends a notification that the handover is successful to the MM module.
[0048] Reference Figure 4 Taking the switching from UTRAN mode to GSM mode as an example, the working principle of the dual-mode switching method for a mobile terminal of the present invention is explained.
[0049] After the mobile terminal 3G module receives the handover command issued by the network, it submits the handover request to the URRC module. After proper processing, the URRC module sends a switching request from UTRAN mode to GSM mode to the adaptation device.
[0050] The adaptation device forwards the handover request to the GRRC module. After receiving the request, the GRRC module submits an asynchronous handover request command to the physical layer. After the physical layer completes the processing, it returns a response message to the GRRC module;
[0051] After the GRRC module receives the response from the physical layer, it starts a timer to ensure that it receives the physical information message containing the time advance from the network;
[0052] When the GRRC module receives the physical information message, it closes the timer and sends a notification to the physical layer to confirm that the asynchronous handover has been completed. After that, the GRRC module requests the data link layer to establish the RR link of the GSM network and requests the data link After the link is established, the layer sends a message that the handover has been successfully completed to the network;
[0053] After the GRRC module receives the confirmation message of the successful link establishment of the data link layer, it notifies the adaptation device that the switch to the GSM mode has been successfully completed. After receiving the message, the adaptation device forwards the notification to the URRC module. At this point, the process ends.
[0054] The dual-mode switching method of the mobile terminal of the present invention provides interface encapsulation for message transfer between different modes, realizes unified management, and facilitates later maintenance.

[0057] The second interface unit 60, after receiving the switching command of the first RRC module, forwards it to the second RRC module, and completes the message interaction between the first RRC module and the second RRC module, so as to realize the mode switching of the second RRC module.
[0058] The above-mentioned first RRC module is a GRRC module, and the second RRC module is a URRC module, or the first RRC module is a URRC module and the second RRC module is a GRRC module.
[0059] The above-mentioned mode switching is switching from GSM mode to UTRAN mode or switching from UTRAN mode to GSM mode.

[0063] The GRRC module parses the message and sends a handover notification to the adaptation device 40;
[0064] The first interface unit 50 forwards the switching command to the MM module;
[0065] The GRRC module sends a request to suspend the current main signaling connection to the data link layer;
[0066] After receiving the suspend response message returned by the data link layer, the GRRC module sends a switch start request to the URRC module through the second interface unit 60;
[0067] The adaptation device 40 requests the physical layer to deactivate the current GSM network resources;
[0068] After receiving the deactivation resource confirmation sent back by the physical layer, the second interface unit 60 sends a handover request to the URRC module of the URRC network;
[0069] The URRC module sends a notification that the handover is successful to the adaptation device 40. After that, the second interface unit 60 notifies the GRRC module that it has successfully switched to the URRC network;
[0070] The GRRC module sends the release of the old GSM network resources to the data link layer, and after receiving the confirmation of the completion of the link release from the data link layer, informs the adaptation device 40 that the handover from the GRRC network to the URRC network has been successfully completed;
