Referring to FIG. 2, a method for dual mode switching of a mobile terminal according to the present invention is provided, including:

Step 101: After receiving a handover command of the first RRC module, forwarding to the MM module and the second RRC module;

Step 102: Perform message interaction between the first RRC module and the MM module and the second RRC module to implement mode switching between the MM module and the second RRC module.

The first RRC module is a GRRC module, 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.

The above mode is switched from GSM mode to UTRAN mode or UTRAN mode to GSM mode.

Referring to FIG. 3, the GSM mode is switched to the UTRAN mode as an example to illustrate the working principle of the mobile terminal dual mode switching method of the present invention.

The physical layer of the mobile terminal receives the handover command sent by the network and forwards it to the data link layer; the data link layer unpacks the data, and transmits the complete handover command to the GRRC module;

The GRRC module parses the message and sends a handover notification to the adaptation device;

The adaptation device forwards the handover command to the MM module;

The GRRC module sends a request to the data link layer to suspend the current primary signaling connection;

After receiving the pending response message sent by the data link layer, the GRRC module sends a start handover request to the URRC module by using the adaptation device.

The adaptation device requests the physical layer to activate the current GSM network resource;

After receiving the deactivation resource acknowledgement sent by the physical layer, the adaptation device sends a handover request to the URRC module of the UTRAN network; The URRC module sends a notification of successful handover to the adaptation device. Afterwards, the adaptation device notifies the GRRC module that the handover to the URRC network is successful;

After receiving the handover command sent by the network, the mobile terminal 3G module submits a handover request to the URRC module. After proper processing, the URRC module sends a handover request from the UTRAN mode to the GSM mode to the adaptation device.

The adaptation device forwards the handover request to the GRRC module. After receiving the request, the GRRC module submits a non-synchronized handover request command to the physical layer, and after the physical layer completes the processing, returns a response message to the GRRC module.

After receiving the physical information message, the GRRC module closes the timer and sends a notification to the physical layer to confirm that the asynchronous handover has been completed. Then the GRRC module requests the data link layer to establish an RR link of the GSM network, and requests the data link. The layer sends a message to the network that the handover has been successfully completed after the link is established;

After receiving the confirmation message of successful establishment of the data link layer, the GRRC module notifies the adaptation device that the handover to the GSM mode has been successfully completed.
