Optionally, the foregoing functional units may be implemented by one device, or jointly implemented by multiple devices, or may be different functional modules in one device, which is not specifically limited in this embodiment of the present application.

4) User equipment usage settings (UE’s usage setting)

A parameter is saved in the UE, which is called UE's usage setting (in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) agreement, it can also be called UE usage setting or UE usage. In this application, the three expressions can be mixed use) and is used to indicate the most important usage of the UE. Currently, there are two possible parameter values for UE’s usage setting: voice-centric or data-centric. All UEs support data-centric, and only some UEs also support voice-centric.

For example, mobile phones and tablets both support Internet access (that is, support data-centric), and mobile phones can also make voice calls but tablets cannot (that is, mobile phones also support voice-centric, while tablets do not support voice-centric). When leaving the factory, the UE’s usage setting of the tablet device can only be set to data-centric, while the UE’s usage setting of the mobile device can be set to either data-centric or voice-centric.

The reason why there is a parameter of UE's usage setting is that the network may or may not support IMS voice (whether the network supports IMS voice is determined by the departmental network policy), considering the user experience, for example, voice calls are very difficult for some users. Important, UE's usage setting mechanism is needed to ensure that such users can get voice services. Specifically, when the UE registers on a network (network, NW), the network will inform the UE whether the network supports IMS through a registration acceptance message. If the UE is voice-centric and the current network does not support IMS, the UE needs to change the radio access technology (Radio Access Technology, RAT) or network according to the protocol until it finds a network that supports IMS; if the UE is voice-centric centric, and the current network supports IMS, it means that the network can meet the voice service of the UE, and the UE can access the network; if the UE is data-centric, whether the current network supports IMS or not will not affect the UE's access to the network. network.

It should be noted that the UE's usage setting is voice-centric only to indicate that ensuring voice calls is an unchangeable requirement of the UE, and it does not mean that the UE can only make voice calls.

At present, UE's usage setting has been configured when the device leaves the factory. If you want to modify it, you can only modify it through AT Command. For ordinary users who do not understand AT command, you cannot modify the value of UE's usage setting. The problem shown in Figure 3. NW1 is an ordinary PLMN that supports IMS. NW2 is a production network similar to enterprise deployment. When NW2 is used for production, it may not support IMS voice. For example, NW2 is used to transmit control commands and return monitoring screens. Due to information security or cost considerations, enterprises do not deploy IMS servers, so NW2 may not support IMS voice when used in production. The user is an employee of the enterprise and holds a UE issued by the enterprise. When the user is at home, the mobile phone issued by the enterprise is the same as an ordinary mobile phone. It works under NW1, and voice is the most basic capability that needs to be guaranteed. Therefore, the UE’s usage setting of this mobile phone is voice-centric. When a user enters the factory park while at work, the enterprise-issued mobile phone needs to be connected to the enterprise private network NW2. However, since NW2 does not support voice, and the user does not understand AT commands and does not know how to modify UE’s usage setting, the mobile phone UE issued by the enterprise will never be able to connect to the enterprise network NW2.

Since it is currently impossible to dynamically and conveniently modify UE’s usage setting, this application provides a method for configuring user equipment. As shown in Figure 4, the method includes the following steps:

S101: The user equipment sends indication information 01 to the access and mobility management functional network element 01, and accordingly, the access and mobility management functional network element 01 receives the indication information 01 from the user equipment.

Wherein, the indication information 01 is used to indicate that the user equipment is centered on voice. Exemplarily, the indication information 01 may be the UE's usage setting set to (or the value is) voice-centric, or may be other information that can indicate that the user equipment is currently voice-centric. The form of 01 is not limited, and any information that allows the access and mobility management function network element 01 to know that the user equipment is voice-centric can be understood as the indication information 01 in this embodiment of the present application.

In an example, the user equipment sends a registration request message to the access and mobility management function network element 01, and the registration request message includes indication information 01. That is to say, the user equipment may indicate to the access and mobility management functional network element 01 that the user equipment is voice-centric during the registration process.

S102: The core network device determines that the configuration of the user equipment in the network is data-centric.

In an example, when the core network device is the access and mobility management function network element 01 , the access and mobility management function network element 01 sends indication information 01 to the unified data management network element 01 . The unified data management network element 01 checks whether the configuration of the user equipment in the network is consistent with the content indicated by the instruction information 01. If not, that is, the configuration saved by the user equipment in the network is data-centric, and the unified data management network element 01 Indication information 02 is sent to the access and mobility management functional network element 01, where the indication information 02 indicates that the configuration of the user equipment in the network is data-centric. Wherein, the indication information 02 may be the UE's usage setting set as data-centric, or the information indicating that the UE's usage setting configured by the user equipment in the network is different from the configuration in the user equipment. In the embodiment of the present application, the indication information 02 The form is not limited, and any information that allows the access and mobility management function network element 01 to know that the configuration of the user equipment in the network is data-centric can be understood as the indication information 02 in the embodiment of the present application. Correspondingly, the access and mobility management functional network element 01 determines that the configuration of the user equipment in the network is data-centric according to the indication information 02 .

In another example, when the core network device is the access and mobility management function network element 01, the access and mobility management function network element 01 sends an existing message to the unified data management network element 01, such as subscription data management (subscriber data management, SDM) get (SDM_get) message. After receiving the message, the unified data management network element 01 sends the UE's usage setting set as data-centric to the access and mobility management function network element 01. The access and mobility management function network element 01 checks whether the configuration of the user equipment in the network is consistent with the content indicated by the instruction information 01 according to the UE's usage setting set as data-centric from the unified data management network element 01, and determines the inconsistency In this case, it can be considered as determining that the configuration of the user equipment in the network is data-centric.

In yet another example, when the core network device is the unified data management network element 01, the unified data management network element 01 receives the instruction information 01 from the user equipment through the access and mobility management function network element 01, that is, access and mobility management The functional network element 01 forwards the indication information 01 from the user equipment to the unified data management network element 01. The unified data management network element 01 determines that the configuration of the user equipment in the network is data-centric according to the UE's usage setting of the user equipment in the network saved locally or in the UDR.

S103: The core network device sends the indication information 03 to the user equipment, and the user equipment receives the indication information 03 accordingly.

Wherein, the indication information 03 is used to indicate that the user equipment is set to be data-centric, or is used to indicate to skip the check of whether the network supports IMS.

When the indication information 03 is used to indicate that the user equipment is set to be data-centric, the indication information 03 may be UE's usage setting set as data-centric, or may be other information indicating that the user equipment is set to be data-centric. Other information indicating that the user equipment is set to be data-centric may be, for example, information indicating modification of the current UE's usage setting, or information indicating that the UE's usage setting of the user equipment in the network is inconsistent with that in the user equipment information. The embodiment of the present application does not limit the form of the indication information 03, and any information that allows the user equipment to know that it is set to be data-centric can be understood as the indication information 03 in the embodiment of the present application.

When the indication information 03 is used to indicate to skip the check of whether the network supports IMS, the indication information 03 may be the UE's usage setting set to data-centric, or may be other instructions indicating that the user equipment skips the check of whether the network supports IMS other information. The embodiment of the present application does not limit the form of the indication information 03, and any information that allows the user equipment to skip the check of whether the network supports IMS can be understood as the indication information 03 of the embodiment of the present application.

In an example, the core network device is the access and mobility management function network element 01, then the access and mobility management function network element 01 may send a registration acceptance message to the user equipment, and the registration acceptance message includes indication information 03; The mobility management function network element 01 sends a configuration update command (configuration update command, CUC) message to the user equipment, and the configuration update command message includes indication information 03. Wherein, the configuration update command message is used for the network to deliver parameters to the UE, that is, for modifying or configuring parameters on the UE.

In another example, the core network device is a unified data management network element 01, then the unified data management network element 01 may send a user parameter update container (user parameters update (UPU) container) to the user equipment, and the user parameter update container includes instruction information 03; or the unified data management network element 01 may send a roaming steering (Steering of roaming, SOR) container to the user equipment, and the roaming steering container includes the instruction information 03. Wherein, the user parameter update container may be included in a message sent by the network to the user equipment, for example, it may be a registration acceptance message, or a non-access stratum (non-access stratum, NAS) transport message (NAS transport message).

It should be noted that when the instruction information 03 is used to indicate that the user equipment is set to be data-centric, the following steps S104a-S108a are performed; when the instruction information 03 is used to indicate that the check of whether the network supports IMS is skipped, the following steps are performed: S104b-S105b described above.

S104a: The user equipment sets itself as data-centric according to the instruction information 03.

Specifically, the user equipment can update the saved UE's usage setting from voice-centric to data-centric according to the instruction information 03, or update the saved UE's usage setting to a value different from the previous value; or the user equipment According to the instruction information 03, the previously saved voice-centric UE's usage setting can be deleted, and the data-centric UE's usage setting can be retained; or the user equipment can mark the previously saved voice-centric UE's usage setting as Invalid, keep the data-centric UE's usage setting or mark the data-centric UE's usage setting as valid.

In the manner of S101-S104a, according to the saved UE's usage setting in the network, instruct the user equipment to modify the UE's usage setting, so as to realize dynamic and convenient modification of the UE's usage setting.

It can be understood that, in an example, the network where the access and mobility management function network element 01 and the unified data management network element 01 are located (for example, NW2 in FIG. 3 ) does not support IMS, so the configuration saved by the user equipment on the network It is data-centric. In order to enable the voice-centric user equipment to access the network, it is necessary to modify the configuration saved in the user equipment itself to data-centric, and execute S101-S104a to achieve this purpose.

However, when the user equipment moves from a network that does not support IMS to a network that supports IMS (such as NW1 in FIG. 3 ), by performing S105a-S108a, the user equipment can be modified from data-centric to voice-centric.

S105a: The user equipment sends indication information 04 to the access and mobility management functional network element 02, and accordingly, the access and mobility management functional network element 02 receives the indication information 04 from the user equipment.

Wherein, the indication information 04 is used to instruct the user equipment to be data-centric. Regarding the indication information 04, reference may be made to the description of the indication information 01 in S101. The difference is that the indication information 01 indicates that the user equipment is voice-centric, while the indication information 04 indicates that the user equipment is data-centric.

In an example, the user equipment sends a registration request message to the network element 02 with the access and mobility management function, and the registration request message includes indication information 04 .

S106a: The core network device determines that the configuration of the user equipment in the network is voice-centric.

In an example, when the core network device is the access and mobility management function network element 02 , the access and mobility management function network element 02 sends indication information 04 to the unified data management network element 02 . The unified data management network element 02 checks whether the configuration of the user equipment in the network is consistent with the content indicated by the instruction information 04. If not, that is, the configuration saved in the network of the user equipment is voice-centric, and the unified data management network element 02 The instruction information 05 is sent to the access and mobility management functional network element 02, where the instruction information 05 indicates that the configuration of the user equipment in the network is voice-centric. For the indication information 05, please refer to the description of the indication information 02 in S102. Configured to be data-centric.

In another example, when the core network device is the access and mobility management function network element 02, the access and mobility management function network element 02 sends existing messages to the unified data management network element 02, such as subscription data Manage get (SDM_get) messages. After receiving the message, the unified data management network element 02 sends UE's usage setting set to voice-centric to the access and mobility management function network element 02. The access and mobility management function network element 02 checks whether the configuration of the user equipment in the network is consistent with the content indicated by the instruction information 04 according to the UE's usage setting set to voice-centric from the unified data management network element 02, and determines the inconsistent In this case, it can be considered that it is determined that the configuration of the user equipment in the network is voice-centric.

In yet another example, when the core network device is the unified data management network element 02, the unified data management network element 02 receives the instruction information 04 from the user equipment through the access and mobility management function network element 02, that is, access and mobility management The functional network element 02 forwards the indication information 04 from the user equipment to the unified data management network element 02 . The unified data management network element 02 determines that the configuration of the user equipment in the network is voice-centric according to the UE's usage setting of the user equipment in the network saved locally or in the UDR.

S107a: The core network device sends the indication information 06 to the user equipment, and the user equipment receives the indication information 06 accordingly.

Wherein, the indication information 06 is used to indicate that the user equipment is set to be voice-centric. Regarding the instruction information 06, please refer to the description of the instruction information 03 in S103. The difference is that the instruction information 06 indicates that the user equipment is set to be voice-centric, while the instruction information 03 indicates that the user equipment is set to be data-centric.

In an example, the core network device is the access and mobility management function network element 02, then the access and mobility management function network element 02 may send a registration acceptance message to the user equipment, and the registration acceptance message includes indication information 06; or the access and mobility management function network element 02 may send a registration acceptance message to the user equipment. The mobility management function network element 02 sends a configuration update command message to the user equipment, and the configuration update command message includes indication information 06 .

In another example, the core network device is the unified data management network element 02, then the unified data management network element 02 may send the user parameter update container to the user equipment, and the user parameter update container includes the instruction information 06; or the unified data management network element 02 A roaming diversion container may be sent to the user equipment, where the roaming diversion container includes indication information 06 .

S108a: The user equipment sets itself as centering on the voice according to the instruction information 06 .

Specifically, how the user equipment sets itself to be voice-centric according to the instruction information 06 can refer to the description in S104a. Data-centric.

It should be noted that S105a-S108a are optional steps. The access and mobility management function network element 02 and the unified data management network element 02 may be located in a network supporting IMS.

S104b: The user equipment skips checking whether the network supports IMS according to the indication information 03.

In an example, the user equipment receives a registration acceptance message from the access and mobility management function network element 01, and the registration acceptance message includes indication information 03 and information indicating whether the network supports IMS. The information indicating whether the network supports IMS can be, for example, IMS-over-PS (packet switched). When IMS-over-PS is not-supported, it means that the network does not support IMS. When IMS-over-PS is supported, it means that the network supports IMS. The user equipment receives the registration acceptance message, and according to the indication information 03 ignores the checking of the content of the information indicating whether the network supports IMS.

In another example, the user equipment receives a registration acceptance message from the access and mobility management functional network element 01 , where the registration acceptance message includes indication information 03 . The user equipment receives the registration acceptance message, and according to the indication information 03, determines not to check whether the registration acceptance message includes information indicating whether the network supports IMS.

It should be noted that the indication information 03 can be replaced with an indication to skip the check of UE's usage setting in the user equipment, that is, after the user equipment receives the indication information 03, it may not check the usage setting of its own user equipment, that is, it does not perform Actions that match the network can be connected to the network by default.

S105b: The user equipment accesses the network.

In an example, the user equipment accesses the network by sending a service request message to the access and mobility management function network element 01, or sending a session establishment request message to the session management network element through the access and mobility management function network element 01, for example, the protocol Data unit (protocol data unit, PDU) session establishment request.

It can be understood that since the user equipment skips checking whether the network supports IMS, even if the network does not support IMS, voice-centric user equipment can still access the network and obtain data services.

The present application provides another method for configuring user equipment. As shown in Figure 5, the method includes the following steps:

S201: The access network device sends the identification information of the first network to the user equipment, and correspondingly, the user equipment receives the identification information of the first network from the access network device.

In an example, before receiving the identification information of the first network, the user equipment is pre-configured with the correspondence between the identification information of one or more networks and the UE's usage setting, that is, the identification information of one network may correspond to one or two UE's usage setting. The identification information of the network may be an identifier (identifier, ID) of a public land mobile network (PLMN) and/or a slice identifier (slice ID) and/or a tracking area identity (tracking area identity, TAI). For example, when the identification information of the network is PLMN ID, the corresponding relationship can be:

{

PLMN ID1--UE usage = "voice-centric";

PLMN ID2--UE usage = "data-centric";

...

}; When the identification information of the network is PLMN ID, slice ID and TAI, the corresponding relationship can be:

{

PLMN ID1–UE’s usage=“voice-centric”--[Slice ID(s)1]--[TAI list1];

PLMN ID2–UE’s usage=“data-centric”--[Slice ID(s)2]--[TAI list2];

...

}.

In an example, the access network device sends a system message to the user equipment, where the system message includes identification information of the first network. Optionally, the system message may also include information indicating whether the first network supports IMS (the information is, for example, IMS-capability).

S202: The user equipment determines to set the user equipment to be voice-centric or data-centric according to the identification information of the first network and the correspondence between the identification information of one or more networks and usage settings of the user equipment.

Specifically, the user equipment searches the received identification information of the first network for the UE's usage setting corresponding to the first network in the corresponding relationship. If the UE's usage setting corresponding to the first network is voice-centric, the user equipment sets itself as voice-centric; if the UE's usage setting corresponding to the first network is data-centric, the user equipment sets itself as data-centric ; If the UE's usage setting corresponding to the first network is data-centric or voice-centric, the user equipment selects one of them.

In an example, when the user equipment also receives the information indicating whether the first network supports IMS, the user equipment matches the first network according to the information indicating whether the network supports IMS and UE's usage setting. Specifically, it can be: UE's usage = "voice-centric" and IMS-capability = "supported", the match is successful; UE's usage = "voice-centric" and IMS-capability = "not-supported", the match fails; UE's usage = " data-centric" and IMS-capability="supported", the match is successful; UE's usage="data-centric" and IMS-capability="not-supported", the match is successful. Wherein, the matching success means that the user equipment can access the first network, and the matching failure means that the user equipment does not access the first network.

It can be understood that by pre-configuring the corresponding relationship in the user equipment, specifying the UE usage setting that the user equipment needs to adopt in different PLMNs/slices/TAIs, it is possible to dynamically and conveniently modify the UE's usage setting.

On the basis of the method shown in FIG. 4 , the present application provides another method for configuring user equipment. As shown in Figure 6, in this method, the access and mobility management function network element is AMF, and the unified data management network element is UDM as an example. The method includes the following steps:

S301: The UE sends a registration request message to the AMF, and the AMF receives the registration request message from the UE accordingly.

Wherein, the registration request message includes UE's usage setting information element (information element, IE). According to the current protocol, the UE with voice-centric capability carries this IE in the registration request message. Therefore, the capability of the UE can be known through whether the IE is present in the message. In addition, the specific value of this IE can be voice-centric or data-centric, indicating the current UE's usage setting of the UE.

S302: If the network supports IMS, perform S303, and if the network does not support it, perform S304.

S303: The network replies a registration acceptance message to the UE, and instructs the network to support IMS voice.

S304: Start judgment, only when the registration request message in S301 includes the UE's usage setting IE (that is, the UE has voice capability), and the value of the UE's usage setting IE is voice-centric (that is, the UE is currently configured as voice-centric), the network It does not support IMS, and only execute S305 when all three conditions are satisfied, otherwise execute S306b or S306c.

S305: The AMF queries the UDM located in the HPLMN for the UE's usage setting (configured UE's usage setting) configured in the network by the UE (written as configured UE's usage setting in the figure, other names are not excluded).

The specific query method can be any one of the following three methods:

Mode 1: AMF sends the current UE's usage setting of the UE (that is, included in the registration request message in S301) to UDM, and UDM checks whether the UE's usage setting is consistent with the configured UE's usage setting. When it is inconsistent, UDM will configure the UE's usage setting Return to AMF.

Method 2: AMF sends UE's current (that is, included in the registration request message in S301) UE's usage setting to UDM, and UDM checks whether UE's usage setting is consistent with configured UE's usage setting. When inconsistent, UDM returns an instruction to AMF Information (indicator) 07, indicating that the UE's usage setting on the current UE is inconsistent with the configured value.

Method 3: The message sent by AMF to UDM is the current standard message without any new content, and UDM sends the configured UE’s usage setting to AMF in the return message, and AMF checks whether the UE’s usage setting is consistent with the configured UE’s usage setting.

When the UE's usage setting is inconsistent with the configured UE's usage setting, execute S306a and S307, otherwise execute S306b or S306c.

S306a: The network replies to the UE with a registration acceptance message, the registration acceptance message including configured UE's usage setting and/or indication information 08, wherein the indication information 08 may have at least one of the following meanings:

1. Indicate that the current UE's usage setting value of the UE is inconsistent with the configured UE's usage setting value. If the current UE's usage setting=voice-centric, the UE needs to modify it to data-centric.

2. Instruct UE to enable/disable UE’s usage setting check.

Optionally, the registration acceptance message also includes information indicating that the network does not support IMS voice, for example, the information is IMS-over-PS=not-supported.

S307: The UE modifies the UE's usage setting value according to the registration acceptance message in S306a, or enables/disables the UE's usage setting check.

This check means that before the UE performs services, it needs to check whether it is matched according to the capabilities of the network and its own configuration. If your own configuration is voice-centric, and the network supports IMS, it is said to be matched. Services can only be performed if they are matched. If the UE cannot be matched, the network needs to be changed.

If the indication information 08 indicates that the UE does not start the UE's usage setting check, the UE does not perform the check and continues to access the network.

Alternatively, starting/not starting the UE's usage setting check can also be referred to as not ignoring/ignoring or not skipping/skipping the UE's usage setting check.

S306b: The network replies a registration acceptance message to the UE, and indicates that the network does not support IMS voice.

S306c: The network replies a registration rejection message to the UE, optionally indicating that the reason for the rejection is that the network does not support IMS voice.

It should be noted that the AMF in this method can be replaced by the MME in the 4G network or other network elements performing similar functions in the future network, and the UDM can be replaced by UDR or other network elements performing similar functions in the future network.

Through this method, the network can refresh the UE's usage setting on the UE through the registration acceptance message or indicate whether the UE considers the UE's usage setting, so as to realize dynamic and convenient modification of the UE's usage setting.

On the basis of the method shown in FIG. 4 , the present application provides another method for configuring user equipment. As shown in Figure 7, in this method, the access and mobility management function network element is AMF, and the unified data management network element is UDM as an example. The method includes the following steps:

S401: The UE sends a registration request message to the AMF, and the AMF receives the registration request message from the UE accordingly.

Wherein, the registration request message includes UE's usage setting IE. According to the current protocol, the UE with voice-centric capability carries this IE in the registration request message. Therefore, the capability of the UE can be known through whether the IE is present in the message. In addition, the specific value of this IE can be voice-centric or data-centric, indicating the current UE's usage setting of the UE.

S402: The network replies a registration acceptance message to the UE, indicating whether the current network supports IMS voice.

S403: Start judgment, only when the registration request message of S401 includes UE's usage setting IE (that is, UE is capable of voice), and the value of UE's usage setting IE is voice-centric (that is, UE is currently configured as voice-centric), And only when the network does not support IMS, that is, when all three conditions are satisfied, S404 is executed.

S404: Referring to S305, the AMF goes to the UDM to query the configured UE's usage setting of the UE, and executes S405 and S406 only when the UE's usage setting in S401 is inconsistent with the configured UE's usage setting.

S405: The network sends a configuration update command (CUC) message to the UE, the message including configured UE's usage setting and/or indication information 08, wherein the indication information 08 may have at least one of the following meanings:

2. Instruct UE to enable/disable UE’s usage setting check.

Among them, the CUC message is a non-access stratum (non-access stratum, NAS) message in the user parameter update (User parameters update, UCU) process, which is used for the network to send parameters to the UE, that is, to modify or configure the UE on the UE. parameter.

S406: The UE modifies the UE's usage setting value according to the CUC message in S405, or starts/disables/ignores/does not ignore/skips/does not skip the UE's usage setting check.

Through this method, the UE first registers to a PLMN according to the existing standards and performs the registration process. After the registration process, if necessary, the network refreshes the UE’s usage setting through the UCU process.

On the basis of the method shown in FIG. 4 , the present application provides another method for configuring user equipment. As shown in Figure 8, in this method, the access and mobility management function network element is AMF, and the unified data management network element is UDM as an example. The method includes the following steps:

S501: The UE sends a registration request message to the AMF, and the AMF receives the registration request message from the UE accordingly.

S502: The network replies a registration acceptance message to the UE, indicating whether the current network supports IMS voice.

S503: Start judgment, only when the registration request message of S501 includes UE's usage setting IE (that is, UE is capable of voice), and the parameter value of UE's usage setting IE is voice-centric (that is, UE is currently configured as voice-centric), And only when the network does not support IMS, that is, when all three conditions are satisfied, S504 is executed.

S504: The AMF sends the UE's usage setting value of the current UE included in the registration request message in S501 to the UDM, and the UDM receives the UE's usage setting value of the current UE from the AMF accordingly.

S505: The UDM judges whether the received UE's usage setting is consistent with the UE's configured UE's usage setting, and if not, execute S506a and S507a or S506b and S507b.

S506a: The UDM sends a user parameter update container (UPU container) to the UE through the AMF, and the User parameters update container carries configured UE's usage setting and/or indication information 2.

The indication information 2 can have at least one of the following meanings:

1. The current UE’s usage setting value of the UE is inconsistent with the configured UE’s usage setting value. If the current UE’s usage setting=voice-centric, the UE needs to modify it to data-centric;

2. Instruct UE to start/not start/ignore/do not ignore/skip/do not skip UE’s usage setting check.

S507a: The UE modifies the UE's usage setting value according to the UPU container in S506a, or starts/disables/ignores/does not ignore/skips/does not skip the UE's usage setting check.

S506b: The UDM sends a Roaming Steering (SOR) container to the UE through the AMF, and the SOR container carries the PLMN list;

S507b: The UE switches the current PLMN according to the PLMN list in S506b.

Specifically, the UE can search according to the PLMNs included in the PLMN list in order from high to low priority, so as to switch from the current PLMN to the PLMN in the PLMN list.

Through this method, the UE first registers to a PLMN according to the existing standards and performs the registration process, and then the network refreshes the UE’s usage setting through the UPU process or instructs the UE to migrate to other PLMNs through the SOR process.

On the basis of the method shown in FIG. 5 , this application provides another method for configuring user equipment. As shown in Figure 9, the method includes the following steps:

S601: The HPLMN pre-configures a list for the UE, and the list includes the UE's usage setting value that the UE needs to adopt in a certain PLMN and/or slice and/or TAI list.

Wherein, the list may be stored on the SIM card, or may exist on the terminal device. The list is, for example:

{

PLMN ID1--UE usage="voice-centric"--[Slice IDs]--[TAI list];

PLMN ID2--UE usage="data-centric"--[Slice IDs]--[TAI list];

...

}.

S602: The base station broadcasts the identifier of a certain PLMN and/or the identifier of a slice and/or the TAI.

In an example, the base station also broadcasts information on whether the network supports IMS voice. Wherein, the information of whether the network supports IMS voice may be included in system information (system info). It can be understood that currently the information is notified to the UE by the network through a registration acceptance or rejection message during the registration process, but in this embodiment of the application, the information is included in the system message and broadcast.

S603: During the current PLMN selection process, the UE needs to consider the pre-configured list in S601 and the information in the system message in S602, and select a PLMN that matches successfully.

Among them, the specific matching rules can be:

□ UE usage = "voice-centric" and IMS-Capability = "supported" in the system message, the matching is successful;

□ UE usage = "voice-centric" and IMS-Capability = "not-supported" in the system message, the matching fails;

□ UE usage = "data-centric" and IMS-Capability = "supported" in the system message, the matching is successful;

□UE usage = "data-centric" and IMS-Capability = "not-supported" in the system message, the match is successful.

Through this method, a list is pre-configured on the UE to indicate the UE’s usage setting that the UE needs to use in different PLMN/slice/TAI lists. In addition, the system information of the base station can be extended to broadcast whether the core network supports IMS. UE selects the appropriate network according to the pre-configured list and system information to realize the adaptation of UE’s usage setting in different networks.
