As shown in FIG. 2, this embodiment provides a tracking area update method, including:

Step S201: When the terminal includes at least two user identification modules, use one user identification module of the at least two user identification modules to perform TAU of each of the at least two user identification modules.

In this embodiment, the tracking area update method is applied to the terminal. The terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, or an Internet of Things device.

In this embodiment, if a terminal includes at least two user identification modules, it means that the mobile terminal includes two or more user identification modules. In short, the terminal may include N user identification modules, and N may be 2 or a positive integer greater than 2.

The terminal is a terminal including a multi-user identification module, and the behavior mode of the multi-user identification module terminal may be dual-card dual-standby single-pass, dual-card dual-standby dual-pass, three-card three-standby, etc.

The subscriber identification module may be a subscriber identification module (SIM, Subscriber Identification Module) card that exists in the form of a separate individual or an integrated subscriber identification module (e-SIM, embedded Subscriber Identification Module) that exists inside the terminal in an integrated form, and so on.

In this embodiment, the two or more user identification modules contained in the terminal all move with the movement of the terminal, so the current locations of these user identification modules are the same, so when performing TAU, It is also updated to the same geographic area or network area.

In this embodiment, in order to save power consumption, when the terminal includes two or more user identification modules, one user identification module is used to perform TAU. In this way, compared to using multiple or each user identification module to perform TAU, The power consumption generated by repeated TAU between the terminal and the network side is reduced, and the standby time of the terminal is extended.

In this embodiment, the TAU may include: periodic TAU and aperiodic TAU. For the periodic TAU, the terminal will perform a TAU every cycle, periodically update its stored TAI, and report its current TA to the core network. During TAU, a TAU timer will be set. If the TAU timer expires, it means that a period has passed since the last periodic TAU, and TAU will be performed.

The aperiodic TAU may be TAU when a trigger event is met. For example, if the terminal receives a tracking area (Tracking Area Identity, TAI) list carried in a system message sent by a base station at its current location and is different from the TAI stored in itself, it is considered that the terminal has entered a new TA and needs to update the TAU.

Through TAU update, the core network will store the TA where the terminal is located. If the core network needs to page the terminal, it will send a paging message to the terminal in the corresponding TA to successfully page the terminal. In some embodiments, the step S201 may include:

Use one user identification module of the at least two user identification modules to send a TAU request, where the TAU request includes: among the at least two user identification modules, other user identification modules other than the one user identification module The identification information.

In some embodiments, the core network may know that the terminal includes two or more user identification modules, and the core network may also not know that the terminal includes two or more user identification modules. In order to easily know that the TAU request sent by the terminal using one user identification module is the TAU for all user identification modules included in the terminal, the terminal will carry the identification information of other user identification modules in the TAU request.

For example, the terminal includes SIM1, USIM2, and eSIM3; if SIM1 is used to send a TAU request, in order to inform the core network that this TAU request is to perform TAU on SIM1, USIM2, and eSIM3 included in the terminal at the same time, the TAU request will carry Identification information of USIM2 and eSIM3.

The identification information of SIM1 may have been notified to the network side during the message exchange process such as random access request between the SIM and the base station, so there is no need to carry it in the TAU request again to reduce the bit overhead of the TAU request.

The TAU request is transmitted to the core network element of the core network through the base station. The core network elements include, but are not limited to, mobile management entities (Mobile Management Entity, MME) or Access and Mobility Management Functions (Access and Mobility Management Function, AMF).

In some embodiments, the step S201 may include:

When the terminal includes at least two user identification modules, and the network to which the at least two user identification modules are connected belongs to the same operator, use one user identification module of the at least two user identification modules to perform The TAU of each of the at least two user identification modules.

In some embodiments, the at least two user identification modules included in the terminal may belong to the same operator, or may also belong to different operators.

In this embodiment, if at least two user identification modules belong to the same operator, only one user identification module will be used for TAU.

In other embodiments, if multiple operators share the same communication network or complete network integration, even if the at least two user identification modules belong to different operators, one user identification module can be used to perform TAU, instead of each user identification module to perform their own TAU.

In some embodiments, the step S201 may further include:

When the terminal includes at least two user identification modules, the network to which the at least two user identification modules are connected belongs to the same operator, and each user identification module of the at least two user equipment modules is in an idle state , Using one user identification module of the at least two user identification modules to perform TAU of each of the at least two user identification modules.

In this embodiment, before performing TAU, each user identification module may be in an idle state. The TAU request may be carried in a message that the terminal has completed a random access process and radio resource control establishment with the base station.

After receiving the TAU request, the core network updates the TA where the terminal is stored in itself, and then sends a TAU accept (Accept) message to the terminal to indicate that the TAU update is completed. The TAU received message may carry the TAI of the TA currently located.

In some embodiments, as shown in FIG. 3, the method further includes:

Step S202: Send a notification indicating that TAU has been performed to other user identification modules in the at least two user identification modules.

Since a user identification module is used to complete TAU, the user identification module needs to inform other user identification modules that the TAU is completed, and will send a notification to inform other user identification modules that the notification informs that TAU is completed. If the base station has issued a new TAI, the notification will also carry the new TAI, so that other user terminals can update their stored TAI in synchronization with the user identification module of the core network for TAU.

In some embodiments, the notification may also carry TAU configuration information for core network reconfiguration. The TAU configuration information includes but is limited to TAI and/or TAU timer.

In some embodiments, as shown in FIG. 4, the method further includes:

Step S200a: receiving TAU configuration information of each of the at least two user identification modules;

Step S200b: Select one user identification module for the TAU from the at least two user identification modules;

The step S201 includes:

Using the selected user identification module, TAU of each of the at least two user identification modules is performed according to the TAU configuration information of the selected user identification module.

Before performing TAU, the terminal may receive the TAU configuration information from the network side. The TAU configuration information includes but is not limited to: TAI and/or TAU timer.

After receiving the TAU configuration information, since the terminal includes multiple user identification modules, in this embodiment, a user identification module of the user TAU is selected.

In some embodiments, for example, step S200b may include at least one of the following:

Select cell information in a user identification module with a higher frequency of use to perform the TAU;

Select the user identification module that performed the service data communication last time to perform the TAU.

In some embodiments, the method further includes:

Receiving TAU configuration information of one of the at least two user identification modules;

The step S201 may include:

A user identification module corresponding to the received TAU configuration information is used to perform TAU according to the received TAU configuration information.

In some embodiments, the core network knows that the terminal contains multiple user identification modules, and the same TAU configuration information is configured for these user identification modules. At this time, only one TAU configuration information can be sent to one user identification module. The TAU configuration information sent by each user identification module can reduce the information interaction between the core network and the terminal, reduce signaling overhead, and save the power consumption of the terminal.

As shown in FIG. 5, this embodiment provides a tracking area update method, including:

Step S301: Configure the tracking area TAU configuration information for the terminal;

Step S302: Send the TAU configuration information;

Step S303: Receive a tracking area TAU request sent based on the TAU configuration information, where the TAU request includes: a TAU request sent by a terminal including at least two user identification modules using one user identification module.

The tracking area update method provided in this embodiment may be a core network element of the application core network.

For example, a core network element such as MME or AMF performs TAU configuration for the terminal, and TAU configuration information will be generated.

The TAU configuration information can be used by one user identification module among the at least two user identification modules to perform TAU, for example, sending a TAU request based on the TAU configuration information.

In some embodiments, the TAU request includes: among the at least two user identification modules, identification information of other user identification modules other than the one user identification module.

Assuming that a TAU request sent by a user identification module carries identification information of other user identification modules, core network elements such as MME can consider the TAU request to be a TAU request for multiple user identification module TAUs, and carry the TAU request at the same time The user identification module with identification information and the user identification module sending the TAU request simultaneously perform TAU. In some cases, the updated TA after the TAU of these user identification modules is the same, or the new TAU configuration information generated based on the TAU request is the same.

In some embodiments, the method further includes:

According to the identification information of the user identification module carried in the TAU request, at least two user identification modules belonging to the same terminal are determined.

If a TAU request carries identification information of other user identification modules, the network element of the core network can also determine from the TAU request whether a terminal contains multiple user identification modules, and which user identification modules the terminal contains .

In some embodiments, before the terminal is attached, the core network can also determine whether the terminal includes multiple user identification modules and which user identification modules are included according to the historical interaction records of the terminal with the core network before the terminal is attached this time.

In some embodiments, the step S301 may include:

If it is determined that the at least two user identification modules belong to the same terminal, configure the same TAU configuration information for each user identification module in the at least two user identification modules; otherwise, configure the same TAU configuration information for each user identification module in the at least two user identification modules The TAU configuration information allocated and configured by the identification module.

When performing TAU configuration information, if the core network knows that a terminal contains multiple user identification modules, it will configure the same TAU configuration information for these user identification modules, thereby simplifying TAU configuration. If the core network does not know that these user identification modules belong to the same terminal, the core network will separately configure the TAU configuration information for each user identification module. The TAU configuration information configured for different user identification modules can be the same or different.

In some embodiments, the method further includes:

When the same TAU configuration information is configured for the at least two user identification modules, the TAU configuration information is sent to each user identification module of the at least two user identification modules, or to the at least two users A user identification module in the identification module sends the TAU configuration information.

In this embodiment, if at least two user identification modules of the terminal are configured with the same TAU configuration information, the core network can send TAU configuration information to each user identification module separately, and one user identification module can be randomly selected, or according to certain The strategy selects a user identification module to choose to send the TAU configuration information to a user identification module. For example, the most frequently used SIM included in the same terminal is selected to send the TAU configuration information, etc., so as to reduce the signaling bits generated by sending the TAU configuration information and reduce the power consumption of the terminal.

In some embodiments, the TAU configuration information includes at least one of the following: a tracking area list TAI; and a tracking area timer.
