Description

Multi-mode terminal position updating method and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for updating a location of a multimode terminal.

background

wireless communication networks have evolved from second Generation mobile communication systems (2G, 2nd Generation; e.g., global system for mobile communications (GSM)), third Generation mobile communication systems (3G, 3rd Generation; e.g., Wideband Code Division Multiple Access (WCDMA)/time division synchronous code division multiple access (TD-SCDMA) (TDs)/code division multiple access 2000(CDMA2000)), to fourth Generation mobile communication systems (4G, 4TD Generation; e.g., Long Term Evolution (LTE) systems).

the terminal supporting simultaneous working of LTE and GSM (SGL TE) is a terminal with LTE/TDS and GSM (general packet radio system (GPRS)/Enhanced Data for GSM Evolution (EDGE)) multimode dual-standby single-card capability, and can simultaneously stand by (including registering and executing tasks) on LTE (and/or TDS) and GSM networks so as to simultaneously support GSM voice service and LTE (and/or TDS) data service.

the SGLTE terminal may adopt a dual stack structure, and includes a main stack (stack 1) and an auxiliary stack (stack 2), where the stack 1 includes a module supporting LTE/TDS/GSM packet switched domain (PS) communication technology, and the stack 2 includes a module supporting GSM circuit switched domain (CS) communication technology. Generally, when the LTE and/or TDS network service is available and the GSM network is also available, the terminal performs a PS data service through the LTE and/or TDS in the stack 1, performs a CS voice and short message service through the GSM in the stack 2, and when both the LTE and TDS network services are not available and only the GSM network service is available, the terminal combines the GSM processing module of the stack 2 to the stack 1, and performs a GSM PS (i.e., GPRS or EDGE) and CS service through the stack 1, so as to achieve the purpose of saving power.

The terminal needs to register with the network to use voice or data services provided by the network, and needs to perform periodic location update to the network to maintain a link with the network and a registration state, and if the terminal does not perform location update to the network within a specified period, the network will speak the terminal to implicitly de-register (identifier detach), which will result in that the terminal will not use network services until the next successful registration. For example, when other terminals call a terminal in the implicit deregistered state, a prompt of "called party powered off" is received.

As shown in fig. 1, a dual stack operation process of a terminal in an SGLTE mode is a location update process for a CS service, and specifically includes:

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

and 2, when the 3G (or 4G) network signal coverage is lost, the terminal CS domain and the PS domain are both registered in the GSM, the GSM CS is switched to the stack 1 from the stack 2, the state of the T3212 of the stack 1 is an activated state (Active), and the state of the T3212 of the stack 2 is a terminated state (Stopped). However, T3212 in stack 2 is still running.

and 3, recovering the coverage of the 3G (or 4G) network signal, reselecting the TDS of the stack 1 by the PS domain of the terminal, operating a periodic location update timer T3212 by the TDS CS of the stack 1, reselecting and switching the GSM CS from the stack 1 to the stack 2, setting the state of the T3212 timer of the stack 1 to be in a termination state, and setting the state of the T3212 timer of the stack 2 to be in an activation state. At this point, the T3212 timer of the TDS CS of stack 1 and the T3212 timer of the GSM CS of stack 2 are running simultaneously, and the time values of the two timers may be different, e.g., the time at which the T3212 timer of stack 2 is now shorter.

and 4, losing the 3G network signal coverage, registering the terminal CS domain and the PS domain in GSM, switching the GSM CS from the stack 2 to the stack 1, setting the state of T3212 of the stack 1 to be an activated state, setting the state of T3212 of the stack 2 to be a terminated state, and simultaneously operating T3212 of the stack 1 and T3212 of the stack 2.

and 5, when the T3212 of the stack 2 is overtime, the T3212 state of the stack 1 is in an activated state at this time, and the information is sent to the stack 1 for processing, but because the T3212 timer of the stack 1 runs, the T3212 overtime information of the stack 2 is not processed, that is, the terminal does not initiate a periodic location updating process to the network.

in the existing double stack operation process of the SGLTE terminal, the situation that the terminal cannot send a position updating request to a network after a T3212 timer is overtime exists, so that the network implicitly registers the terminal, an error prompt of shutdown of a called party is sent when the terminal is called, and normal use of the terminal is influenced.

In the embodiment, the terminal prohibits starting the location updating timer of the designated network domain in the first stack in the stack splitting state, so that the terminal only has one location updating timer of the designated network domain to operate after the terminal is switched from the stack splitting state to the stack combining state, thereby avoiding that the location updating cannot be performed in time due to the fact that two location updating timers of services of the designated network domains operate in the stack combining state and the timeout information cannot be processed when the location updating timer of the second stack is timed in the prior art, and ensuring that the multi-mode terminal adopting two or more stack structures can perform the location updating in time.

with reference to the first aspect, in a first possible implementation manner, the method further includes:

When the terminal determines that the termination condition of the location updating timer of the designated network domain is met, terminating the location updating timer of the designated network domain of the first stack;

and when the terminal determines that the starting condition of the location updating timer of the designated network domain is met, starting the location updating timer of the designated network domain at the second stack.

When the terminal is in the stack closing state, if the position updating timer of the designated network domain of the second stack is determined to be started, and the termination condition of the position updating timer of the designated network domain is determined to be met, terminating the position updating timer of the designated network domain of the second stack;

And the terminal terminates the location updating timer of each appointed network domain running in the first stack and the second stack and initiates a location updating request to the network.

In this embodiment, when the location update timer of the designated network domain needs to be terminated, the location update timer of each designated network domain running in the first stack and the second stack is terminated, and a location update request is initiated to the network, thereby avoiding that, in the prior art, when the location update timers of the designated network domains of the second stack run and the location update timers of the designated network domains of the first stack run, the location update cannot be performed in time due to the fact that timeout information cannot be processed when the location update timers of the designated network domains of the second stack timeout, and ensuring that a multimode terminal adopting two or more stack structures can perform location update in time.

Detailed Description

in order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the following embodiments, the terminal includes at least a first stack and a second stack, where the first stack operates a service other than a service of a designated network domain of the first mobile communication system in a stack splitting state, and the second stack operates the service of the designated network domain of the first mobile communication system; and the service of the designated network domain of the first mobile communication system in the second stack is merged into the first stack to run in the stack merging state.

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

specifically, taking the example that the first mobile communication system is a 2G network, the designated network domain is a CS domain, and the terminal is a multimode terminal with a dual stack structure, the terminal includes a first stack and a second stack, and is divided into a stack splitting state and a stack combining state according to a coverage condition of the 3G or 4G network, where when the terminal is covered by the 3G or 4G network, the first stack runs a service other than a service of the designated network domain of the 2G network, and the second stack runs a service of the designated network domain of the 2G network, and is the stack splitting state; and 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 run, and the operation is in a stack merging state.

in order to ensure that a multimode terminal adopting two or more stack structures can update the position on time, so as to avoid the situation that the terminal cannot receive other terminal calls because the position update is not performed in time and is implicitly registered by a network, the following three embodiments are provided in the embodiment of the invention, and the terminal can update the position on time by controlling a position updating timer.

In the first embodiment, as shown in fig. 2, the detailed method process of the terminal controlling the location update timer is as follows:

step 201: the terminal judges whether the current state is in a stack splitting state;

Step 202: and when the terminal determines that the terminal is in the stack splitting state currently, the terminal forbids the first stack to start the position updating timer of the designated network domain.

Specifically, the terminal prohibits starting the location update timer of the designated network domain on the first stack in the stack splitting state, and starts or runs the location update timer of the designated network domain only on the second stack if it is determined that the start condition of the location update timer of the designated network domain is met.

the terminal determines that the starting condition of the location updating timer of the designated network domain is met in the stack splitting state, starts the location updating timer if the location updating timer of the designated network domain of the second stack is not started, and continues to run the location updating timer if the location updating timer of the designated network domain of the second stack is started.

In a preferred embodiment, the terminal terminates the location update timer of each designated network domain running in the first stack and the second stack when determining that the termination condition of the location update timer of the designated network domain is met in the stack splitting state or the stack combining state.

preferably, the terminal terminates the location update timer of the designated network domain of the stack in which the service of the designated network domain of the first mobile communication system is located when determining that the termination condition of the location update timer of the designated network domain is satisfied in the stack splitting state or the stack combining state, and terminates the location update timer of the designated network domain of another stack if the termination fails.

The preferred embodiment ensures that the running location updating timer of the designated network domain can be terminated when the termination condition is met, avoids initiating an unnecessary location updating process caused by not timely terminating the location updating timer of the designated network domain, and ensures the normal running of the terminal.

Preferably, the terminal determines that the location update timer of the designated network domain of the first stack is started in the stack combining state in the stack splitting state, and the location update timer of the designated network domain of the first stack is still running when the stack combining state is changed to the stack splitting state; terminating the location update timer of the designated network domain of the first stack upon determining that a location update timer termination condition of the designated network domain is satisfied; and when the condition that the starting condition of the location updating timer of the specified network domain is met is determined, starting the location updating timer of the specified network domain only at the second stack.

In the preferred embodiment, after the terminal terminates the location update timer of the designated network domain of the first stack in the stack splitting state, the location update timer is not allowed to be restarted, thereby avoiding the occurrence of the situation that the location update timers of the two designated network domains run after the terminal is switched from the stack splitting state to the stack combining state.

Preferably, when the terminal is in a stack closing state, if it is determined that the location update timer of the designated network domain of the second stack is started, and it is determined that the termination condition of the location update timer of the designated network domain is met, terminating the location update timer of the designated network domain of the second stack; and when the condition that the starting condition of the location updating timer of the specified network domain is met is determined, starting the location updating timer of the specified network domain only at the first stack.

Preferably, the first mobile communication system is a global system for mobile communications (GSM); before step 201 is executed, the terminal in this embodiment determines that it is in a first operating mode, where the first operating mode supports both GSM and 3G services, or the first operating mode supports both GSM and 4G services. For example, the first operating mode is the SGLTE mode.

In the embodiment of the present invention, the terminal determines that the termination condition of the location update timer in the specified network domain is satisfied, including but not limited to any one of the following cases:

The terminal executes the position updating process and receives a position updating acceptance message or a position updating rejection message;

The terminal receives the authentication refusing message;

the terminal receives a first mobile management message in a normal service state, or the terminal completes the setting of a security mode in the process of establishing a mobile management connection;

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

the terminal is powered off or a user identity identification card is replaced, such as a SIM card or a USIM card;

if the position updating timer of the designated network domain of the first stack runs for a set time length, the position updating timer of the designated network domain of the first stack meets an end condition, or if the position updating timer of the designated network domain of the second stack runs for the set time length, the position updating timer of the designated network domain of the second stack meets the end condition.

In this embodiment, the location update timer has the following two determination modes when it times out:

firstly, setting the initial value of a position updating timer as a set value, and when the position updating timer starts to count down from the set value until the value reaches zero, determining that the position updating timer is overtime;

secondly, setting the initial value of the position updating timer to be zero, starting timing by the position updating timer from the zero value until reaching the preset set value, and determining that the position updating timer is overtime.

the terminal determines that the location updating timer of the designated network domain of the first stack or the second stack is overtime, and initiates a location updating process of the service of the designated network domain.

In the embodiment of the present invention, when the terminal determines a Normal Service (Normal Service) for switching to a mobility management IDLE state (MM IDLE) or a sub-state of Attempting location Update (Attempting to Update), it determines that a condition for starting a location Update timer of the specified network domain is satisfied.

the following is described with reference to a process of location update timer control provided in a first embodiment of an embodiment, where the specific embodiment takes a service in a specified network domain of a 2G network as a CS service as an example, and for a case where the service in the specified network domain of the 2G network is a PS service, the following process may be referred to for execution, and the CS service only needs to be replaced by the PS service, where a terminal in the specific embodiment includes a primary stack (i.e., a first stack) and a secondary stack (i.e., a second stack), and the specific embodiment is to update a location of the CS service, and specifically as follows:

Step 1, the terminal is powered on under 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 secondary stack, that is, the initial value of T3212 is set to 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 to count down.

And 2, when the terminal loses the coverage of the 3G network signal, the CS domain and the PS domain of the terminal are both registered in the GSM, the GSM CS is switched from the auxiliary stack to the main stack, namely, the terminal is switched from the stack splitting state to the stack combining state, at the moment, the activation state of the T3212 timer is also switched from the auxiliary stack to the main stack, namely, the T3212 state of the main stack is the activation state, the T3212 state of the auxiliary stack is the termination state, but the T3212 still counts down in the auxiliary stack because the T3212 is started in the auxiliary stack.

If the terminal determines that the termination condition of any one position updating timer is met in the stack closing state, attempting to terminate the T3212 of the main stack, and if the T3212 of the main stack is running, successfully terminating the T3212 of the main stack; otherwise, the termination of the T3212 of the primary stack fails, an attempt is made to terminate the T3212 of the secondary stack, and the termination of the T3212 of the secondary stack succeeds.

in the stack closing state, if T3212 is terminated, when the terminal determines to switch to a normal service in the mobility management idle state or a sub-state in which location update is attempted, T3212 is restarted in the main stack.

And 3, when the coverage of the 3G network signal is recovered, the GSM CS is switched from the main stack to the auxiliary stack again, namely the PS service is carried out through the main stack, the CS service is carried out through the auxiliary stack, namely the terminal is switched from the stack combining state to the stack separating state, the activation state of the T3212 timer is switched from the main stack to the auxiliary stack, namely the T3212 state of the main stack is set to be the termination state, and the T3212 state of the auxiliary stack is set to be the activation state.

in the stack splitting state, if the T3212 of the primary stack is not started, the terminal is not allowed to start the T3212 on the primary stack running the PS service, and only starts the T3212 on the secondary stack; if the T3212 of the primary stack is started, when the T3212 of the primary stack meets the termination condition and terminates, if the terminal is still in the stack splitting state, the T3212 is started only in the secondary stack when the start condition of the location update timer is met.

If the terminal determines that the termination condition of any one position updating timer is met in the stack splitting state, attempting to terminate the T3212 of the auxiliary stack, and if the T3212 of the auxiliary stack is running, successfully terminating the T3212 of the auxiliary stack; otherwise, the termination of the T3212 of the secondary stack fails, an attempt is made to terminate the T3212 of the primary stack, and the termination of the T3212 of the primary stack succeeds.

in the stack splitting state, if T3212 is terminated, when the terminal determines to switch to a normal service in the mobility management idle state, or tries to perform a location update substate, T3212 is restarted at the secondary stack.

and 4, the terminal loses the 3G signal coverage again, the terminal CS domain and the PS domain are both registered in the GSM, the GSM CS service is switched from the auxiliary stack to the main stack, namely the terminal is switched from the stack splitting state to the stack combining state, the state of the T3212 timer of the main stack is an activated state, and the state of the T3212 timer of the auxiliary stack is a terminated state.

And 5, if the T3212 of the auxiliary stack runs overtime in the stack closing state, namely counting down to a zero value, sending the overtime information to the main stack for processing, wherein the T3212 of the auxiliary stack is processed because the T3212 of the main stack is not started, namely the terminal initiates a periodic location updating process to the GSM network.

based on the same inventive concept, in the second embodiment, as shown in fig. 3, the detailed method process of the terminal for controlling the location update timer is as follows:

Step 301: the method comprises the steps that a terminal determines that at least one of a position updating timer of a designated network domain of a first stack and a position updating timer of the designated network domain of a second stack runs for more than a set time length in a stack splitting state or a stack combining state;

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 invention, if a position updating timer of a designated network domain runs in a first stack and a position updating timer of the designated network domain runs in a second stack, if one of the position updating timers is overtime, the position updating timer of the designated network domain in the first stack and the position updating timer of the designated network domain in the second stack are terminated; if only the first stack runs the location updating timer of the designated network domain, terminating the location updating timer when the location updating timer is overtime; if only the location update timer of the designated network domain is running in the second stack, the location update timer is terminated when the location update timer times out.

In this embodiment, the location update timer for each of the specified network domains running in the first and second stacks is terminated when the location update timer for the specified network domain needs to be terminated, that is, when the location update timers of the designated network domain run in the first stack and the second stack simultaneously, if one of the location update timers is overtime, terminating the location update timer of the designated network domain running in each stack and initiating a location update request to the network, thereby avoiding the situation that the position updating timers of two specified network domains are running in the stacking state in the prior art, when the position updating timer of the designated network domain of the second stack is overtime, the overtime information cannot be processed to cause that the position cannot be updated in time, thereby ensuring that the multimode terminal adopting two or more stack structures can update the position in time.

in this embodiment, the following two determination methods are used when the location update timer runs out of time (exceeds the set time length):

Preferably, the terminal determines that at least one of the location update timer of the designated network domain of the first stack and the location update timer of the designated network domain of the second stack satisfies a termination condition in the stack splitting state or the stack combining state, and terminates the location update timer of each designated network domain running in the first stack and the second stack.

corresponding to the preferred embodiment, the terminal starts the location update timer of the domain in which the service of the specified network domain is located when determining that the location update timer start condition of the specified network domain is satisfied. The preferred embodiment is such that in case that the location update timer of the specified network domain is started again and no switching of the stack combining state to the stack splitting state occurs, only one location update timer of the specified network domain is running.

Specifically, when the terminal is in a stack closing state and when the starting condition of the location update timer of the designated network domain is determined to be met, the location update timer of the designated network domain is started at the first stack. And when the terminal is in a stack splitting state and the starting condition of the location updating timer of the designated network domain is determined to be met, starting the location updating timer of the designated network domain at the second stack.

In this embodiment of the present invention, the terminal determines 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 satisfies the termination condition under any one of the following enumerated conditions, which are only exemplified herein, and the scope of the present invention is not limited thereto:

the terminal receives the authentication refusing message;

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

the terminal is powered off or the subscriber identity module card is replaced, such as a SIM card or a USIM card.

Preferably, the first mobile communication system is GSM; before executing step 301, the terminal in this embodiment determines that the terminal is in a first working mode, where the first working mode supports both GSM CS domain services and 3G services, or supports both GSM CS domain services and 4G services. For example, the first operating mode is the SGLTE mode.

a description is given below to a process of controlling a location update timer provided in the second embodiment by using a specific embodiment, where the specific embodiment takes a service in a specified network domain as a CS service as an example, and for a case where the service in the specified network domain is a PS service, the following process may be referred to for execution, and only the CS service needs to be replaced by the PS service, where a terminal in the specific embodiment includes a primary stack and a secondary stack, and the specific embodiment is a location update for the CS service, which is specifically as follows:

And 2, when the terminal loses the coverage of the 3G network signal, the CS domain and the PS domain of the terminal are both registered in the GSM, the GSM CS is switched from the auxiliary stack to the main stack, namely, the terminal is switched from the stack splitting state to the stack combining state, at the moment, the activation state of the T3212 timer is also switched from the auxiliary stack to the main stack, namely, the T3212 state of the main stack is the activation state, the T3212 state of the auxiliary stack is the termination state, but the T3212 in the auxiliary stack still counts down because the T3212 is started in the auxiliary stack.

if the terminal determines that the termination condition of any one position updating timer is met in the stack closing state, attempting to terminate the T3212 of the main stack, and if the T3212 of the main stack is running, successfully terminating the T3212 of the main stack; otherwise, the termination of T3212 of the primary stack fails; whether the termination of T3212 of the primary stack is successful or not, an attempt is made to terminate T3212 of the secondary stack.

and 3, when the coverage of the 3G network signal is recovered, the PS service of the terminal is reselected to the 3G network of the main stack, a CS (such as TDS CS) of the 3G network of the main stack runs or starts T3212 to periodically update the position, the GSM CS is switched from the main stack to the auxiliary stack again, namely the PS service is carried out through the main stack, the CS service is carried out through the auxiliary stack, the terminal is switched from a stack combining state to a stack separating state, the activation state of a T3212 timer is switched from the main stack to the auxiliary stack, namely the T3212 state of the main stack is a termination state, and the T3212 state of the auxiliary stack is an activation state. At this time, the T3212 of the primary stack and the T3212 of the secondary stack run simultaneously, but the time values of the two are different, and the time value of the T3212 of the secondary stack is shorter.

if the terminal determines that the termination condition of any one position updating timer is met in the stack splitting state, attempting to terminate T3212 of the auxiliary stack, and if the T3212 of the auxiliary stack is running, successfully terminating the T3212 of the auxiliary stack; otherwise, the termination of the T3212 of the secondary stack fails; whether the termination of T3212 of the secondary stack is successful or not, an attempt is made to terminate T3212 of the primary stack.

in the stack splitting state, if T3212 is terminated, when the terminal determines to switch to a normal service in the mobility management idle state or to attempt a sub-state of location update, T3212 is restarted at the secondary stack.

and 4, the terminal loses the 3G network signal coverage again, the terminal CS domain and the PS domain are both registered in the GSM, and the GSM CS service is switched from the auxiliary stack to the main stack, namely the terminal is switched from the stack splitting state to the stack combining state, the state of the T3212 timer of the main stack is an activated state, and the state of the T3212 timer of the auxiliary stack is a terminated state. T3212 of the primary stack and T3212 of the secondary stack are running (continuing to count down) at the same time.

Step 5, if in the stack closing state, the T3212 of the auxiliary stack runs overtime, i.e., counts down to a zero value, and sends the overtime information to the main stack for processing, at this time, the terminal may have the following two processing modes:

the first processing mode is to judge whether a T3212 of the main stack is running, if yes, terminate the T3212 of the main stack and initiate a location updating process to the network;

In the second processing mode, the terminal directly tries to terminate T3212 of the primary stack, and whether the termination is successful or not, a periodic location update process is initiated to the network, wherein if the termination of T3212 of the primary stack is successful, it indicates that T3212 is running in the primary stack, and if the termination of T3212 of the primary stack fails, it indicates that no T3212 is running in the primary stack.

Based on the same inventive concept, in the third embodiment, as shown in fig. 4, a detailed method flow for the terminal to control the location update timer is as follows:

Step 401: the terminal determines that switching between a stack splitting state and a stack combining state occurs;

step 402: the terminal determines the minimum value of the remaining timing duration of the location updating timer of the designated network domain of the first stack and the remaining timing duration of the location updating timer of the designated network domain of the second stack;

Step 403: the terminal sets the value of the location updating timer of the designated network domain of the stack where the service of the designated network domain is located according to the minimum value determined in step 402, so that the remaining timing duration of the location updating timer of the stack where the service of the designated network domain is located is the minimum value.

corresponding to the first setting mode of the position updating timer, the current remaining timing length of the position updating timer is the current value of the position updating timer, and if the position updating timer is not started, the remaining timing length of the position updating timer is the initial value (i.e. the set value) of the position updating timer.

corresponding to the second setting mode of the position updating timer, the remaining time duration of the position updating timer is the difference between the preset set value and the current value of the position updating timer, and if the position updating timer is not started, the remaining time duration of the position updating timer is the preset set value (i.e. the timeout value).

preferably, the terminal terminates the location update timer of each designated network domain running in the first stack and the second stack when determining that at least one of the location update timer of the designated network domain of the first stack and the location update timer of the designated network domain of the second stack satisfies a termination condition in a stack splitting state or a stack combining state.

specifically, when the terminal is in a stack closing state, the location update timer of the designated network domain is started at the first stack when the start condition of the location update timer of the designated network domain is determined to be satisfied. And when the terminal is in a stack splitting state and the starting condition of the location updating timer of the designated network domain is determined to be met, starting the location updating timer of the designated network domain at the second stack.

In this 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 satisfies the termination condition according to any one of the following situations, which is only an example, and the scope of the present invention is not limited thereto:

The terminal receives the authentication refusing message;

if the location update timer of the designated network domain of the first stack runs for more than a set time length, the location update timer of the designated network domain of the first stack meets an end condition, or if the location update timer of the designated network domain of the second stack runs for more than a set time length, the location update timer of the designated network domain of the second stack meets an end condition.

In the embodiment of the present invention, when the terminal determines to switch to a Normal Service (Normal Service) of a mobility management IDLE state (MM IDLE) or tries to perform a location Update (addressing to Update) sub-state, it determines that a condition for starting a location Update timer of the specified network domain is satisfied.

preferably, the first mobile communication system is GSM; before executing step 401, the terminal in this embodiment determines that the terminal is in a first working mode, where the first working mode supports both GSM CS domain service and 3G service, or supports both GSM CS domain service and 4G service. For example, the first operating mode is the SGLTE mode.

A procedure of location update timer control provided in the third embodiment is described below with a specific embodiment, where the specific embodiment takes a service in a specified network domain as a CS service as an example, and for a case where the service in the specified network domain is a PS service, reference may be made to the following procedure, and only the CS service needs to be replaced by the PS service, where a terminal in the specific embodiment includes a main stack (i.e., a first stack) and an auxiliary stack (i.e., a second stack), and the specific embodiment is location update for the CS service, specifically as follows:

Step 1, the terminal is started up under 2G and 3G (or 4G) networks, the PS domain is registered on the 3G network, the CS domain is registered on the GSM network, the PS domain service and the CS domain service respectively work on a main stack and an auxiliary stack, namely the terminal is in a stack splitting state. Starting a periodic location update timer T3212 on the secondary stack, that is, setting an initial value of T3212 to a set value (or timeout value), for example, setting T3212 to a preset time duration for T3212 in the cell system information and starting to count down. Here, the value of T3212 of the secondary stack is denoted 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 GSM, and the GSM CS is switched from the auxiliary stack to the main stack, namely the terminal is switched from the stack splitting state to the stack combining state, at this time, the activation state of the T3212 timer is also switched from the auxiliary stack to the main stack, namely the T3212 state of the main stack is the activation state, and the T3212 state of the auxiliary stack is the termination state, but because the T3212 is started in the auxiliary stack, the T3212 is still operated in the auxiliary stack, namely the T3212 in the auxiliary stack is still counting down.

And 3, when the 3G network signal coverage is recovered, reselecting the PS service of the terminal to the 3G network of the main stack, wherein the CS (such as TDS CS) of the 3G network of the main stack runs or starts T3212, and the value of the T3212 of the main stack is represented as T3212_ S1.

The GSM CS is switched from the main stack to the auxiliary stack again, namely PS business is carried out through the main stack, CS business is carried out through the auxiliary stack, the terminal is switched from a stack combining state to a stack separating state, the activation state of the T3212 timer is switched from the main stack to the auxiliary stack, namely the T3212 state of the main stack is set to be a termination state, and the T3212 state of the auxiliary stack is set to be an activation state. At this time, T3212 of the primary stack and T3212 of the secondary stack run simultaneously, and T3212_ S2 is made to be the minimum value of T3212_ S2 and T3212_ S1, and the count-down starts from this value.

if T3212 of the secondary stack is overtime, the terminal initiates a periodic location update procedure to the network, and if T3212 of the primary stack is still running at this time, T3212 of the primary stack is terminated.

If the terminal determines that the termination condition of any one position updating timer is met in the stack splitting state, attempting to terminate the T3212 of the auxiliary stack, and if the T3212 of the auxiliary stack is running, successfully terminating the T3212 of the auxiliary stack; otherwise, the termination of the T3212 of the secondary stack fails; whether the termination of T3212 of the secondary stack is successful or not, an attempt is made to terminate T3212 of the primary stack.

in the stack splitting state, if T3212 is terminated, when the terminal determines to switch to the normal service in the mobility management idle state or tries to perform the location update substate, T3212 is restarted at the secondary stack.

and 4, the terminal loses the 3G signal coverage again, the terminal CS domain and the PS domain are both registered in the GSM, the GSM CS service is switched from the auxiliary stack to the main stack, namely the terminal is switched from the stack splitting state to the stack combining state, the state of the T3212 timer of the main stack is an activated state, and the state of the T3212 timer of the auxiliary stack is a terminated state. When the T3212 of the primary stack and the T3212 of the secondary stack are running simultaneously (continuing to count down), the value of T3212_ S1 is the minimum value of T3212_ S1 and T3212_ S2, and the count down is started from this value.

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