Description

Multimode terminal location updating method and device

Technical field

The present invention relates to the field of communications technologies, and in particular, to a multimode terminal location update method and device.

Background technique

The wireless communication network is via a second generation mobile communication system (2G, 2nd Generation; for example, Global System for Mobile Communications (GSM)), a third generation mobile communication system (3G, 3rd Generation; for example, Wideband Code Division Multiple Access (WCDMA)/Time Division Synchronization Code Division Multiple Access (TD-SCDMA) (TDS)/Code Division Multiple Access 2000 (CDMA2000) evolves to fourth generation mobile communication systems (4G, 4td Generation; such as Long Term Evolution (LTE) systems).

A terminal supporting LTE and GSM simultaneous operation (SGL TE) is a multimode dual standby with LTE/TDS and GSM (General Packet Radio System (GPRS)/GSM Evolution Enhanced Data Service (EDGE)) A single-card capable terminal capable of standby (including registration and execution of tasks) on both LTE (and/or TDS) and GSM networks, thereby supporting both GSM voice services and LTE (and/or TDS) data services.

The SGLTE terminal can adopt a dual stack structure, including a main stack (Stack 1) and a secondary stack (Stack 2), wherein the stack 1 includes a module supporting LTE/TDS/GSM packet switching domain (PS) communication technology, and the stack 2 includes GSM support. Module of Circuit Switched Domain (CS) communication technology. In general, when LTE and/or TDS network services are available and the GSM network is also available, the terminal performs PS data service through LTE and/or TDS in the stack 1, and performs CS voice and short message service through the GSM in the stack 2. When both LTE and TDS network services are unavailable, and only GSM network services are available, the terminal will stack the GSM processing module of Stack 2 to Stack 1, and perform GSM PS (ie, GPRS or EDGE) and CS services through Stack 1 to achieve power saving. purpose.

The terminal needs to register with the network to use the voice or data service provided by the network. The terminal also needs to perform periodic location update to the network to maintain the link with the network and the registration status. The location update is not successfully made to the network within the specified period. The network will say that the terminal is implicitly detached (Implicit detach), which will cause the terminal to be unable to use the network service before the next successful registration. For example, when another terminal calls a terminal that is in an implicit deregistration state, it will receive a prompt that the called party is powered off.

The dual stack operation process of the terminal in the SGLTE mode is as shown in FIG. 1 , which is a location update process for the CS service, specifically:

Step 1: The terminal is powered on in the 2G and 3G (or 4G) networks, the CS is registered on the GSM, and the periodic location update timer T3212 is started on the stack 2, that is, the timer is set to an initial value (also called a timeout value). ).

Step 2: When the 3G (or 4G) network signal coverage is lost, both the CS domain and the PS domain of the terminal are registered in GSM, and the GSM CS is switched from the stack 2 to the stack 1, and the state of the T3212 of the stack 1 is set to the active state (Active). ), the state of T3212 of stack 2 is set to the end state (Stopped). However, T3212 in Stack 2 is still running.

Step 3: 3G (or 4G) network signal coverage recovery, terminal PS domain reselection to stack 1 TDS, stack 1 TDS CS also runs a periodic location update timer T3212, GSM CS is switched from stack 1 reselection to stack 2. The state of the T3212 timer of Stack 1 is set to the termination state, and the state of the T3212 timer of Stack 2 is set to the active state. At this time, the T3212 timer of the TDS CS of the stack 1 and the T3212 timer of the GSM CS of the stack 2 are simultaneously operated, and the time values of the two timers may be different. For example, the time of the T3212 timer of the stack 2 is short.

Step 4, the 3G network signal coverage is lost, the terminal CS domain and the PS domain are both registered in GSM, and the GSM CS is switched from the stack 2 to the stack 1, and the state of the T3212 of the stack 1 is set to the active state, and the state of the T3212 of the stack 2 is set. Set to the termination state, T3212 of Stack 1 and T3212 of Stack 2 are running at the same time.

Step 5: T3212 of stack 2 times out. At this time, the T3212 state of stack 1 is active. The information is sent to stack 1 for processing. However, since stack 1 itself has a T3212 timer running, the T3212 timeout information of stack 2 is not. Processing, that is, the terminal does not initiate a periodic location update process to the network.

During the operation of the existing SGLTE terminal dual-stack, the terminal cannot send the location update request to the network after the T3212 timer expires, so that the network implicitly registers the terminal, resulting in the end. When the terminal is called, an error message indicating that the called party is turned off is issued, which affects the normal use of the terminal.

detailed description

The present invention will be further described in detail with reference to the accompanying drawings, in which FIG. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the following embodiments, the terminal includes at least a first stack and a second stack. In the stacking state, the first stack runs a service other than the service of the specified network domain of the first mobile communication system, and the second stack runs the first. The service of the specified network domain of the mobile communication system; the service of the specified network domain of the first mobile communication system in the second stack in the stacked state is merged into the first stack to run.

Preferably, the service of the designated network domain is a circuit switched domain service or a packet switched domain service.

Specifically, the first mobile communication system is a 2G network, the designated network domain is a CS domain, and the terminal is a multi-mode terminal having a dual-stack structure. The terminal includes a first stack and a second stack, according to a 3G or 4G network. The coverage is divided into a split state and a stack state. When the terminal has 3G or 4G network coverage, the first stack runs services other than the services of the specified network domain of the 2G network, and the second stack runs the 2G network. The service of the specified network domain is in a split state; when the 3G or 4G network coverage is lost, the service of the specified network domain of the 2G network in the second stack is merged into the first stack to be in a stacked state.

In the embodiment of the present invention, in order to ensure that the multi-mode terminal adopting two or more stack structures can perform location update on time, in order to prevent the terminal from being implicitly registered by the network due to the location update. The following three embodiments are provided to ensure that the terminal can perform location update on time by controlling the location update timer.

In the first embodiment, as shown in FIG. 2, the detailed method for controlling the location update timer by the terminal is as follows:

Step 201: The terminal determines whether it is currently in a split state;

Step 202: When the terminal determines that it is currently in the split state, the terminal does not start the location update timer of the specified network domain on the first stack.

Specifically, in the split state, the terminal prohibits starting the location update timer of the specified network domain on the first stack. If it is determined that the location update timer start condition of the specified network domain is met, the terminal only starts or runs the designation on the second stack. The location update timer for the network domain.

The terminal determines, in the split state, that the location update timer start condition of the specified network domain is met, and if the location update timer of the specified network domain of the second stack is not started, the location update timer is started, if The location update timer of the specified network domain of the second stack is started, and the location update timer is continued to run.

In a preferred implementation manner, the terminal terminates each specified network domain running in the first stack and the second stack when determining that the location update timer termination condition of the specified network domain is satisfied in the split state or the stack state. Location update timer.

Preferably, the terminal terminates the location update timing of the designated network domain of the stack of the service of the specified network domain of the first mobile communication system when the terminal determines that the location update timer termination condition of the specified network domain is satisfied in the split state or the stack state. If the termination fails, the location update timer of the specified network domain of the other stack is terminated.

The preferred embodiment ensures that the location update timer of the specified network domain can be terminated when the termination condition is met, and the location update timer of the specified network domain is not terminated in time to initiate an unnecessary location update process, thereby ensuring that an unnecessary location update process is initiated. The normal operation of the terminal.

Preferably, in the split state, the terminal determines that the location update timer of the specified network domain of the first stack is started in the stack state, and the designated network domain of the first stack when changing from the stack state to the split state The location update timer is still running; determining that the location update timer of the specified network domain is terminated when the location update timer termination condition of the specified network domain is satisfied; determining that the When the location update timer start condition of the network domain is specified, the location update timer of the specified network domain is started only on the second stack.

In the preferred embodiment, after the terminal terminates the location update timer of the specified network domain of the first stack in the split state, the terminal does not allow the location update timer to be restarted, thereby preventing the terminal from switching from the split state to the stack state. , occurs when two location update timers of the specified network domain are running.

Preferably, when the terminal is in the stacked state, if it is determined that the location update timer of the specified network domain of the second stack has been started, determining that the location update timer termination condition of the specified network domain is satisfied, the designating the second stack is terminated. A location update timer of the network domain; when it is determined that the location update timer start condition of the specified network domain is met, the location update timer of the specified network domain is started only on the first stack.

Preferably, the first mobile communication system is a Global System for Mobile Communications (GSM); the terminal in this embodiment determines that it is in the first working mode before performing step 201, and the first working mode supports both GSM and 3G services, or The first mode of operation supports both GSM and 4G services. For example, the first mode of operation is the SGLTE mode.

In the embodiment of the present invention, the terminal determines that the location update timer termination condition that meets the specified network domain includes, but is not limited to, any one of the following situations:

The terminal performs a location update process, and receives a location update accept message or a location update reject message;

The terminal receives the authentication rejection message;

Receiving, by the terminal, the first mobility management message in a normal service state, or completing the security mode setting in the mobility management connection establishment process;

The terminal responds to the paging message sent by the network, and receives the first layer 3 message except the radio resource message;

The terminal shuts down or replaces the user identification card, such as replacing the SIM card or USIM card;

If the location update timer of the specified network domain of the first stack reaches the set duration, the location update timer of the specified network domain of the first stack satisfies the termination condition, or the location update timer of the specified network domain of the second stack When the operation reaches the set duration, the location update timer of the specified network domain of the second stack satisfies the termination condition.

In this embodiment, the location update timer expires in the following two ways:

First, the initial value of the location update timer is set to a set value, and the location update timer starts counting down from the set value until the value reaches zero, and determines that the location update timer expires;

Secondly, the initial value of the position update timer is set to a value of zero, and the position update timer starts counting from the zero value until the preset set value is reached, and it is determined that the position update timer expires.

The terminal determines that the location update timer of the specified network domain of the first stack or the second stack times out, and initiates a location update process of the service of the specified network domain.

In the embodiment of the present invention, when the terminal determines to switch to the normal service (MM IDLE) of the mobility management idle state (MM IDLE) or the sub-state of the attempt to perform the location update (Attempting to Update), it is determined that the location of the specified network domain is met. Update the condition of the timer.

The following is a description of the process of the location update timer control provided in the first embodiment of the specific embodiment. The specific embodiment uses the service of the specified network domain of the 2G network as the CS service as an example for the specified network of the 2G network. The case where the service of the domain is a PS service can be performed by referring to the following process, and only the CS service needs to be replaced with the PS service. In this embodiment, the terminal includes a primary stack (ie, a first stack) and a secondary stack (ie, a second stack). And the specific embodiment is a location update for the CS service, as follows:

Step 1. The terminal is powered on in the 2G and 3G (or 4G) networks. The PS domain is registered on the 3G network of the main stack, the CS domain is registered on the GSM network, and the periodic location update timer T3212 is started on the auxiliary stack, that is, the T3212 is set. The initial value is a set value (or a timeout value). For example, T3212 is set to a preset duration of T3212 broadcasted in the cell system information and starts counting down.

Step 2: When the terminal loses the coverage of the 3G network signal, the terminal CS domain and the PS domain are both registered in the GSM, and the GSM CS is switched from the secondary stack to the primary stack, that is, the terminal switches from the split state to the stacked state, and the T3212 is timed. The activation state of the device is also switched to the main stack by the auxiliary stack, that is, the T3212 state of the main stack is set to the active state, and the T3212 state of the auxiliary stack is set to the termination state, but since the T3212 is started on the auxiliary stack, the T3212 itself is still counted down on the auxiliary stack. .

If the terminal determines that the termination condition of any of the location update timers is satisfied in the stack state, the terminal attempts to terminate the T3212 of the main stack. If the T3212 of the main stack is running, the T3212 of the main stack is terminated successfully; Otherwise, the T3212 of the primary stack fails to terminate, and attempts to terminate T3212 of the secondary stack terminates the T3212 of the secondary stack.

In the stacked state, if the terminal determines to switch to the normal service of the mobility management idle state or the substate that attempts to perform the location update after the T3212 is terminated, the T3212 is restarted on the main stack.

Step 3: When the coverage of the 3G network signal is restored, the GSM CS is re-switched from the primary stack to the secondary stack, that is, the PS service is performed through the primary stack, and the CS service is performed through the secondary stack, that is, the terminal is switched from the stacked state to the split state, T3212 The active state of the timer is switched from the primary stack to the secondary stack, that is, the T3212 state of the primary stack is set to the termination state, and the T3212 state of the secondary stack is set to the active state.

If the terminal is in the split state, if the T3212 of the main stack is not started, T3212 is not allowed to be started on the main stack running the PS service, and T3212 is only started on the auxiliary stack; if the T3212 of the main stack is started, then the main stack When the T3212 meets the termination condition termination, if the terminal is still in the split state, the T3212 is started only on the secondary stack when the start condition of the location update timer is satisfied.

If, in the split state, the terminal determines that the termination condition of any of the location update timers is met, the T3212 of the secondary stack is attempted to terminate. If the T3212 of the secondary stack is running, the T3212 of the secondary stack is terminated successfully; otherwise, the secondary stack is terminated. T3212 terminates failure and attempts to terminate T3212 of the main stack, then the T3212 of the main stack terminates successfully.

In the split state, if the T3212 terminates, the T3212 is restarted on the secondary stack when the terminal determines to switch to the normal state of the mobility management idle state or attempts to perform the location update substate.

Step 4, the terminal again loses the 3G signal coverage, the terminal CS domain and the PS domain are both registered in the GSM, and the GSM CS service is switched from the secondary stack to the primary stack, that is, the terminal switches from the split state to the stacked state, and the T3212 of the primary stack is timed. The state of the device is set to the active state, and the state of the T3212 timer of the auxiliary stack is set to the termination state.

Step 5: If the T3212 of the secondary stack runs out of time, that is, counts down to zero value, the timeout information is sent to the main stack for processing. Since the T3212 of the primary stack is not started, the T3212 timeout information of the secondary stack is processed. That is, the terminal initiates a periodic location update process to the GSM network.

Based on the same inventive concept, in the second embodiment, as shown in FIG. 3, the detailed method of controlling the location update timer by the terminal is as follows:

Step 301: The terminal determines, in the split state or the stacked state, that at least one of the location update timer of the specified network domain of the first stack and the location update timer of the specified network domain of the second stack exceeds a set duration ;

Step 302: The terminal terminates each location update timer running in the first stack and the second stack, and initiates a location update request to the network.

In the embodiment of the present invention, if the location update timer of the specified network domain is run in the first stack, and the location update timer of the specified network domain is run in the second stack, if one of the location update timers expires, the first is terminated. a location update timer of the specified network domain in the stack and a location update timer of the specified network domain in the second stack; if only the location update timer of the specified network domain is run in the first stack, the timer is updated at the location When the timeout expires, the location update timer is terminated; if only the location update timer of the specified network domain is run in the second stack, the location update timer is terminated when the location update timer expires.

In this embodiment, when it is necessary to terminate the location update timer of the specified network domain, the location update timer of each of the specified network domains running in the first stack and the second stack is terminated, that is, on the first stack and When the location update timer of the specified network domain is simultaneously running in the second stack, if one of the location update timers expires, the location update timer of the specified network domain running in each stack is terminated, and a location update is initiated to the network. Request, thereby avoiding the prior art in the stack state, because there are two location update timers of the specified network domain running, when the location update timer of the specified network domain of the second stack times out, the timeout information cannot be The location update caused by the processing cannot be performed in time, which ensures that the multi-mode terminal adopting two or more stack structures can perform location update on time.

In this embodiment, the location update timer runs out of time (beyond the set duration) in the following two ways:

Preferably, the terminal determines the bit of the specified network domain of the first stack in the split state or the stacked state At least one of the location update timers of the update timer and the specified network domain of the second stack satisfies the termination condition, terminating the location update timer of each of the specified network domains running in the first stack and the second stack.

Corresponding to the preferred embodiment, the terminal starts a location update timer of the domain of the service of the specified network domain when determining that the location update timer start condition of the specified network domain is met. In the preferred embodiment, in the case where the location update timer of the specified network domain is started again and the stacking state is not switched to the split state, only one location update timer of the specified network domain is running.

Specifically, when the terminal determines that the location update timer start condition of the specified network domain is met when the terminal is in the stacked state, the location update timer of the specified network domain is started on the first stack. When the terminal determines that the location update timer start condition of the specified network domain is met when the terminal is in the split state, the location update timer of the specified network domain is started on the second stack.

In the embodiment of the present invention, the terminal determines, in any one of the following enumerated cases, that the location update timer of the specified network domain of the first stack and the location update timer of the specified network domain of the second stack are at least One satisfies the termination condition, which is merely an enumeration here, and the scope of protection of the present invention is not limited thereto:

The terminal receives the authentication rejection message;

The terminal receives the first mobility management message in a normal service state, or the terminal completes the security mode setting in the mobility management connection establishment process;

The terminal shuts down or replaces the user identification card, such as replacing the SIM card or USIM card.

Preferably, the first mobile communication system is GSM; the terminal in this embodiment is performing step 301. Previously, it was determined that it was in the first working mode, and the first working mode supported both the GSM CS domain service and the 3G service, or both the GSM CS domain service and the 4G service. For example, the first mode of operation is the SGLTE mode.

The process of controlling the location update timer provided in the second embodiment is described by using a specific embodiment. The specific embodiment is described by taking the service of the specified network domain as the CS service as an example, and the service of the specified network domain is PS. The service can be performed by referring to the following process, and only the CS service needs to be replaced by the PS service. In this embodiment, the terminal includes a primary stack and a secondary stack, and in this specific embodiment, the location update for the CS service is as follows: :

Step 2: When the terminal loses the coverage of the 3G network signal, the terminal CS domain and the PS domain are both registered in the GSM, and the GSM CS is switched from the secondary stack to the primary stack, that is, the terminal switches from the split state to the stacked state, and the T3212 is timed. The activation state of the device is also switched from the secondary stack to the primary stack, that is, the T3212 state of the primary stack is set to the active state, and the T3212 state of the secondary stack is set to the termination state. However, since the T3212 is started on the secondary stack, the T3212 in the secondary stack is still in progress. Countdown.

If, in the stacked state, the terminal determines that the termination condition of any of the location update timers is satisfied, the T3212 of the main stack is attempted to be terminated. If the T3212 of the main stack is running, the T3212 of the main stack is terminated successfully; otherwise, the main stack is terminated. T3212 terminates failure; regardless of whether the T3212 of the main stack terminates successfully, it tries to terminate T3212 of the auxiliary stack.

Step 3: When the 3G network signal coverage is restored, the PS service of the terminal is reselected to the 3G network of the main stack, and the CS of the 3G network of the main stack (such as TDS CS) runs or starts T3212 to periodically update the location, GSM CS The main stack is re-switched to the secondary stack, that is, the PS service is performed through the primary stack, and the CS service is performed through the secondary stack. The terminal is switched from the stacked state to the split state, and the T3212 timer is activated. The main stack is switched to the secondary stack, that is, the T3212 state of the primary stack is set to the termination state, and the T3212 state of the secondary stack is set to the active state. At this time, the T3212 of the main stack and the T3212 of the auxiliary stack run simultaneously, but at this time, the time values of the two are different, and the time value of the T3212 of the auxiliary stack is shorter.

If the terminal determines that the termination condition of any one of the location update timers is met, the terminal attempts to terminate the T3212 of the secondary stack. If the T3212 of the secondary stack is running, the T3212 of the secondary stack is terminated successfully; otherwise, the secondary The T3212 of the stack terminates failing; regardless of whether the T3212 of the secondary stack terminates successfully, it attempts to terminate the T3212 of the primary stack.

In the split state, if the T3212 terminates, the T3212 is restarted on the secondary stack when the terminal determines to switch to the normal service of the mobility management idle state or the substate that attempts to perform the location update.

Step 4, the terminal again loses the 3G network signal coverage, the terminal CS domain and the PS domain are both registered in the GSM, and the GSM CS service is switched from the secondary stack to the primary stack, that is, the terminal switches from the split state to the stacked state, and the main stack T3212 The state of the timer is set to the active state, and the state of the T3212 timer of the auxiliary stack is set to the termination state. The T3212 of the main stack and the T3212 of the auxiliary stack are running at the same time (continue counting down).

Step 5: If the T3212 of the secondary stack runs out of time, that is, counts down to zero value, the timeout information is sent to the main stack for processing. At this time, the terminal can have the following two processing modes:

The first processing mode determines whether the main stack has T3212 running, and if so, terminates the T3212 of the main stack, and initiates a location update process to the network;

In the second processing mode, the terminal directly attempts to terminate the T3212 of the main stack, and initiates a periodic location update process to the network regardless of whether the terminal is successfully terminated. If the T3212 of the main stack is successfully terminated, the T3212 is running on the main stack. The termination of the T3212 of the main stack failed, indicating that the main stack does not have T3212 running.

Based on the same inventive concept, in the third embodiment, as shown in FIG. 4, the detailed method for controlling the location update timer by the terminal is as follows:

Step 401: The terminal determines to switch between a split state and a stacked state.

Step 402: The terminal determines a minimum time duration of a location update timer of a specified network domain of the first stack and a minimum time duration of a location update timer of the specified network domain of the second stack.

Step 403: The terminal sets, according to the minimum value determined in step 402, the value of the location update timer of the specified network domain in the stack of the service of the specified network domain, so that the service of the specified network domain is in the stack. The remaining timing of the location update timer is the minimum.

Wherein, corresponding to the first location update timer setting mode, the current remaining timing duration of the location update timer is the current value of the location update timer, and if the location update timer is not started, the location update timer is The remaining timing is the initial value (ie, the set value) of the position update timer.

Corresponding to the second location update timer setting mode, the remaining timing duration of the location update timer is the difference between the preset setting value and the current value of the location update timer. If the location update timer is not started, the location is The remaining timer duration of the update timer is the preset set value (ie, the timeout value).

Preferably, the terminal determines, in the split state or the stacked state, that at least one of the location update timer of the specified network domain of the first stack and the location update timer of the specified network domain of the second stack meets the termination condition Terminating the location update timer for each of the specified network domains running in the first stack and the second stack.

Corresponding to the preferred embodiment, when determining that the location update timer start condition of the specified network domain is met, the terminal starts a location update timer of the domain of the service of the specified network domain. This excellent In a case where the location update timer of the specified network domain is started again and the stack state is not switched to the split state, only one location update timer of the specified network domain is running.

Specifically, when the terminal is in the stacked state, determining that the location update timer of the specified network domain is started on the first stack when the location update timer start condition of the specified network domain is met. When the terminal determines that the location update timer start condition of the specified network domain is met when the terminal is in the split state, the location update timer of the specified network domain is started on the second stack.

In the embodiment of the present invention, the terminal determines that at least one of the location update timer of the first stack and the location update timer of the second stack meets the termination condition according to any one of the following enumerated situations. The scope of protection of the present invention is not limited thereto:

The terminal receives the authentication rejection message;

If the location update timer of the specified network domain of the first stack runs longer than the set duration, the location update timer of the specified network domain of the first stack satisfies the termination condition, or the location update timing of the specified network domain of the second stack If the device runs longer than the set duration, the location update timer of the specified network domain of the second stack satisfies the termination condition.

In the embodiment of the present invention, when the terminal determines to switch to the normal service (MM IDLE) of the mobility management idle state (MM IDLE) or attempts to perform the location update (Attempting to Update) substate, it is determined that the location update of the specified network domain is met. The condition of the timer.

Preferably, the first mobile communication system is GSM; before performing step 401, the terminal in the embodiment determines that it is in the first working mode, and the first working mode supports the GSM CS domain industry at the same time. And 3G services, or support GSM CS domain services and 4G services at the same time. For example, the first mode of operation is the SGLTE mode.

The process of controlling the location update timer provided in the third embodiment is described below by using a specific embodiment. The specific embodiment is described by taking the service of the specified network domain as the CS service as an example, and the service for the specified network domain is PS. The service can be performed by referring to the following process, and only the CS service needs to be replaced with the PS service. In this embodiment, the terminal includes a main stack (ie, a first stack) and a secondary stack (ie, a second stack), and the specific implementation In the example, the location update for the CS service is as follows:

Step 1: The terminal is powered on in the 2G and 3G (or 4G) networks, the PS domain is registered on the 3G network, the CS domain is registered on the GSM network, and the PS domain service and the CS domain service are respectively working on the primary stack and the secondary stack, that is, the terminal. It is in the state of splitting. The periodic position update timer T3212 is started on the auxiliary stack, that is, the initial value of T3212 is set to a set value (or timeout value). For example, T3212 is set as the preset duration of T3212 in the cell system information and the countdown is started. Here, the value of T3212 of the auxiliary stack is represented by T3212_S2.

Step 2: When the terminal loses the coverage of the 3G network signal, the terminal CS domain and the PS domain are both registered in the GSM, and the GSM CS is switched from the secondary stack to the primary stack, that is, the terminal switches from the split state to the stacked state, and the T3212 is timed. The activation state of the device is also switched to the main stack by the auxiliary stack, that is, the T3212 state of the main stack is set to the active state, and the T3212 state of the auxiliary stack is set to the termination state, but since the T3212 is started on the auxiliary stack, the T3212 is still running on the auxiliary stack, that is, The T3212 in the secondary stack is still counting down.

Step 3: When the 3G network signal coverage is restored, the PS service of the terminal is reselected to the 3G network of the main stack, and the CS of the 3G network of the main stack (such as TDS CS) runs or starts T3212, and the value of the T3212 of the main stack is represented as T3212_S1. .

The GSM CS is switched back to the secondary stack by the primary stack, that is, the PS service is performed through the primary stack, the CS service is performed through the secondary stack, the terminal is switched from the stacked state to the split state, and the activation state of the T3212 timer is switched from the primary stack to the secondary stack. That is, the T3212 state of the main stack is set to the termination state, and the T3212 state of the auxiliary stack is set to the active state. At this time, the T3212 of the main stack and the T3212 of the auxiliary stack are simultaneously operated. At this time, T3212_S2 is the minimum value in T3212_S2 and T3212_S1, and the countdown starts from this value.

If the T3212 of the secondary stack times out, the terminal initiates a periodic location update process to the network, and if the T3212 of the primary stack is still running, the T3212 of the primary stack is terminated.

If, in the split state, the terminal determines that the termination condition of any of the location update timers is met, the T3212 of the secondary stack is attempted to terminate. If the T3212 of the secondary stack is running, the T3212 of the secondary stack is terminated successfully; otherwise, the secondary stack is terminated. T3212 terminates failure; regardless of whether the T3212 of the secondary stack terminates successfully, it attempts to terminate the T3212 of the primary stack.

In the split state, if T3212 terminates, T3212 is restarted on the secondary stack when the terminal determines to switch to the normal service of the mobility management idle state or attempts to perform the location update substate.

Step 4, the terminal again loses the 3G signal coverage, the terminal CS domain and the PS domain are both registered in the GSM, and the GSM CS service is switched from the secondary stack to the primary stack, that is, the terminal switches from the split state to the stacked state, and the T3212 of the primary stack is timed. The state of the device is set to the active state, and the state of the T3212 timer of the auxiliary stack is set to the termination state. T3212 of the main stack and T3212 of the auxiliary stack are running at the same time (continue counting down), then let T3212_S1 be the minimum value in T3212_S1 and T3212_S2, and count down from this value.

If the T3212 of the primary stack times out, the terminal initiates a periodic location update process to the network. If the T3212 of the secondary stack is still running, the T3212 of the secondary stack is terminated.
