The mobile terminal differs from the prior art in the protocol stack. Specifically, the protocol stack includes: a CS single standby and a PS dual standby protocol stack module, a first standard access layer, a second standard access layer, and connection management. (CM) business application module, where:

The first standard network is a global mobile communication system (GSM) network, the second standard network is a time division synchronous code division multiple access (TD) network, and the first standard access layer is GSM access. The second standard access layer is a TD access layer; or the first standard network is a TD network, the second standard network is a GSM network, and the first standard access layer is a TD access layer. The second access layer is a GSM access layer.

The CM service application module includes the CC, the SS, the SMS, the SM, and the like. The result of the CM service application module is the same as the prior art, but the function is different from the prior art.

That is, UMM controls GSM-AS and TD-AS to search and reside in GSM and TD. After successful residency, the MM performs location registration on the GSM network; the GMM performs GPRS attach on the TD network.

After the registration of the CS domain and the PS domain is completed, the CS domain of the terminal resides on the GSM network, and the PS domain resides on the GSM network and the TD network, and the CS and PS services can be normally provided.

In addition, the MM module is further configured to receive a CS calling service sent by the CM service application module, and send the CS calling service to the GSM access layer; the GMM module is further configured to receive the The PS calling service sent by the CM service application module is sent, and when the signal of the TD network is detected to be higher than the first threshold, the PS calling service is sent to the TD access layer.

The PS service is transferred to the GSM system (the specific transfer is not the content of the present invention and will not be described in detail herein). It avoids the use of PS services due to the discontinuity of TD network coverage. When the measurement finds that the TD signal recovers well, the SM can transfer the PS service back to the TD network through the GMM.

When the CC, SS, and SMS initiate the CS service, the MM splits the GSM network; when the SM has the PS service, the GMM splits the TD network; when the measurement finds that the TD network signal is relatively poor, the SM passes the GMM to the PS. The service is transferred to the GSM system to avoid the use of the PS service due to the discontinuity of the TD network coverage. When the measurement finds that the TD signal recovers well, the SM can transfer the PS service back to the TD network through the GMM, as shown in Figure 3a.

Further, the MM module is further configured to switch the CS calling service back to the GSM access layer when detecting that the signal of the GSM network is higher than the second threshold. In summary, the above mobile terminal uses a single mobile phone chip, dual radio frequency (dual antenna), can support SIM card or USIM card, and a single user number. The CS domain preferentially resides in the GSM network, and the PS domain resides in the TD network, supporting the CS service and the PS service simultaneously. The terminal chip protocol stack UMM controls GSM-AS and TD-AS to search and relocate simultaneously on the GSM and TD systems. After successful residency, the Protocol Stack Mobility Management (MM) module performs location registration on the GSM network; General Packet Radio Service Technology (GPRS) Mobility Management (GMM) performs GPRS attachment on the TD network. After the registration of the CS domain and the PS domain is completed, the CS domain and the PS domain of the terminal respectively reside on the GSM network and the TD network, and the CS and PS services can be normally provided. When the CC, SS, and SMS initiate the CS service, the MM splits the GSM network; when the SM has the PS service, the GMM splits the TD network; when the measurement finds that the GSM network signal is relatively poor, CC, SS, SMS The CS service is transferred to the TD system through the MM, which avoids the use of the CS service due to the discontinuity of the GSM network coverage.

The mobile terminal can be smoothly upgraded to a dual-mode dual-standby mobile terminal by using a mobile terminal, and the mobile terminal in the embodiment of the present invention uses a single chip, and the existing dual-chip dual-card slot. In comparison, there is a big advantage in reducing cost and power consumption.

The embodiment of the invention further provides a method for performing service by a dual-mode dual-mode dual standby mobile terminal, the method comprising:

Step 1: The mobile terminal uses the first service dual standby and the second service single standby protocol stack to complete the registration process after the first standard network and the second standard network are successfully resident. Specifically, the search registration process includes:

Step 11. The user starts up, and the MM layer notifies the TD-AS layer, the GSM-AS layer, the GSM physical layer,

The TD physical layer respectively turns on the radio frequency and enters the working state; Step 12: After the GSM physical layer and the TD physical layer successfully open the radio, the GSM-AS layer and the TD-AS layer are restored, and the GSM-AS layer and the TD-AS layer are returned to the MM layer;

Step 13. The human interface adaptation layer (MMIA) notifies the MM layer to perform a network search process, and the MM layer sends a search command to the GSM-AS layer and the TD-AS at the same time, requesting to search for a suitable cell in the respective system. Stay

Step 14. The GSM-AS and the TD-AS work simultaneously, requesting the respective physical layer to search for a suitable cell and camping successfully, and then replying to the cell information of the MM layer resident cell;

Step 15: After receiving the cell information that successfully resides, the MM layer initiates a registration process of the CS domain on the GSM system according to the principle of service offload, and initiates a registration process of the PS domain on the TD system; Step 16. When in the CS domain After the PS domain is successfully registered, the GSM physical layer is configured to listen to the CS domain paging, and the TD physical layer is configured to listen to the PS domain paging, and the registration result is reported to the user.

At this point, the search and registration process is completed, and the terminal can perform the calling and called services normally.

Step 2: The mobile terminal performs offloading of the calling service of different standards and performs the calling service at the same time; or, the called service is simultaneously performed.

The mobile terminal can simultaneously perform the calling service of the CS domain and the PS domain, and the processes of calling the calling service of the CS domain and the PS domain are respectively:

(1) CS domain Calling service establishment process for CC call:

Step 21a: The connection establishment request of the CC to initiate the call;

Step 22a: After receiving the connection establishment request, the MM is a CS domain call, and establishes an RR connection in the GSM standard request;

Step 23a: After the RR connection is established, the MM performs the MM connection establishment, and the MM connection of the CC module CS domain is successfully established.

Step 24a: The CC performs a calling process on the established GSM CS domain connection; At this point, the service calling process of the CS domain is completed.

(2) PS domain SM PDP activated calling service establishment process:

Step 21b: The SM initiates a connection establishment request for the SM service.

Step 22b: After receiving the connection establishment request, the GMM is a PS domain service, and requests the TD system. Establish an RRC connection;

Step 23b: After the RRC connection is established, the GMM replies to the SM module, and the PS domain signaling connection is successfully established;

Step 24b: The SM performs a calling process on the established TD standard PS domain signaling connection; At this point, the service calling process of the PS domain is completed.

The mobile terminal can also perform the CS domain and the PS domain called service at the same time, and the processes of performing the CS domain and the PS domain called service are respectively:

(1) CS domain CC's called service establishment process:

Step 31a: The GSM physical layer monitors the CS domain paging of the user all the time;

Step 32a: After listening to the CS domain paging of the user, report the GSM-AS layer to the called party to be established; after the called connection is established, notify the MM that the called service is accessed;

Step 33a: After receiving the notification of the called service, the MM moves to the corresponding appropriate state, waits for the CC message on the network side, and notifies the CC after receiving the network CC message;

Step 34a: After receiving the called message, the CC starts to perform the called service process.

At this point, the called business process of the CS domain is completed.

(2) The establishment process of the called service of the PS domain SM:

Step 31b: The TD physical layer monitors the user's PS domain paging all the time;

Step 32b: After listening to the PS domain paging of the user, reporting the TD-AS layer to notify the GMM module;

Step 33b: After receiving the paging of the PS domain, the GMM module initiates an RRC connection establishment, and responds to the PS domain paging.

Step 34b: After the RRC connection is successfully established, the PS domain signaling connection is established.

Step 35b: After receiving the called SM message, the GMM reports the SM message to the SM module. Step 36b: After receiving the called message, the SM starts to perform the SM called service process.

At this point, the called service process of the PS domain is completed.

In addition, the mobile terminal performs the first service process corresponding to the first standard network, And if the signal of the first-standard network is detected to be lower than the first threshold, and the signal of the second-standard network is higher than the second threshold, the first service is switched to the second-standard network.

Further, after the mobile terminal switches the first service to the second standard network, the method further includes: when the mobile terminal detects that the signal of the first standard network is higher than the first threshold And switching the first service back to the first standard network.

The first standard network is a Global System for Mobile Communications (GSM) network, the second standard network is a Time Division Synchronous Code Division Multiple Access (TD) network, and the first service is a circuit switched (CS) service. The second service is a packet switched (PS) service, the first service domain is a CS domain, and the second service domain is a PS domain; or the first standard network is a TD network, and the second The system is a GSM network, the first service is a PS service, the second service is a CS service, the first service domain is a PS domain, and the second service domain is a CS domain; or, the first The system is a GSM network, and the second system is a Wideband Code Division Multiple Access (WCDMA) network, the first service is a CS service, the second service is a PS service, and the first service domain is a CS. The second service domain is a PS domain.

Specifically, the PS service switching process is as follows:

Step 41: The TD-AS measurement finds that the TD signal is relatively poor, below the threshold, and notifies the GMM; Step 42: After receiving the signal quality notification, the GMM determines that the PS service needs to be moved to the GSM system;

Step 43: Initiating a route update process on the GSM system, informing the network UE to reselect to the GSM system;

Step 44: After the route update succeeds, the GMM notifies the GSM-AS to start listening to the paging of the PS domain; meanwhile, the SM is notified to switch to the GSM standard, and the user plane data is relocated;

Step 45: The TD-AS measurement finds that the TD signal is recovered, and notifies the GMM;

Step 46: After receiving the signal quality notification, the GMM determines that the PS service needs to be moved back to the TD system. Step 47: Initiate a route update process on the TD system to notify the network UE to reselect to the TD system; Step 48, after the route update succeeds, the GMM The GSM-AS is notified to stop listening to the paging of the PS domain. At the same time, the SM is notified to switch to the TD system to perform user plane data relocation.

The above steps show that when the TD network signal is not good, the PS service can be transferred to the GMM. The GSM network is used to avoid the use of the PS service due to the discontinuity of the TD network coverage. When the terminal finds that the TD signal recovers better, the PS service can be transferred back to the TD network through the GMM.

The mobile terminal in the embodiment of the present invention performs the calling and called service, which can not only meet the user's use requirements, but also better achieve the function of service offloading and balancing the network load. Meanwhile, the PS service can also be implemented in the TD network and the GSM. Fast and smooth switching of the network to better meet the user's business needs.
