3) The core network device refers to a device in a Core Network (CN) that provides service support for the user equipment. As shown in fig. 1, which is a schematic diagram of a 5G communication system to which the embodiments of the present application are applicable, a 5G core Network device includes a plurality of Network elements such as an access and mobility management function (access and mobility management function, AMF), a session management function (session management function, SMF), a policy control function (policy control function, PCF), a Network Slice selection function (Network Slice selection function, NSSF), an authentication server function (authentication server function, AUSF), a Network Slice authentication and authorization function (Network Slice-Specific Authentication and Authorization Function, NSSAAF), a unified data management function (unified data management, UDM), a user plane function (user plane function, UPF), an application function (application function, AF), and the like.

Alternatively, the above functional unit may be implemented by one device, or may be implemented by a plurality of devices together, or may be different functional modules in one device, which is not specifically limited in this embodiment of the present application.

4) Usage setting (UE's usage setting) of user equipment

A parameter is stored in the UE, which is called UE's usage setting (also referred to as UE usage setting or UE usage in the third generation partnership project (3rd Generation Partnership Project,3GPP) protocol, and the three expressions may be mixed in this application) and is used to indicate the most important purpose of the UE. Currently, there are two parameter values that are desirable for UE's usage setting: voice-centric or data-centric. All UEs are data-centric supported, only a portion of the UEs also support voice-centric.

For example, both the handset and the tablet are internet enabled (i.e., data-center enabled), and the handset is also capable of making voice calls without the tablet (i.e., the handset also supports voice-center and the tablet does not support voice-center). Then at the time of shipment, the UE's user setting of the tablet device can only be set to data-center, and the UE's user setting of the mobile device can be selected to be set to either data-center or voice-center.

This parameter of UE's user setting is so because the network may or may not support IMS voice (whether the network supports IMS voice is determined by the subnet policy), and considering the user experience, such as voice call is important for some users, it is necessary to ensure that such users must be served by the UE's user setting mechanism. Specifically, when the UE registers on a Network (NW), the network informs the UE of whether the network supports IMS through a registration accept message. If the UE is voice-center and the current network does not support IMS, the UE needs to change radio access technology (Radio Access Technology, RAT) or change networks according to the protocol specification until a network supporting IMS is found; if the UE is voice-center and the current network supports IMS, the network can meet the voice service of the UE, and the UE can access the network; if the UE is data-center, the current network supports or does not support IMS, and the access of the UE to the network is not affected.

It should be noted that, the UE's user setting is voice-center only indicating that the voice call is a requirement that the UE cannot change, and does not mean that the UE can only make voice calls.

AT present, when the device leaves the factory, the UE's usage setting is configured, if the UE's usage setting is to be modified only by AT Command, the value of the UE's usage setting cannot be modified for a common user who does not understand AT Command, so that the problem shown in fig. 3 is caused. NW1 is a generic PLMN supporting IMS, NW2 is a production network like an enterprise deployment, and NW2 may not support IMS voice for production. For example, NW2 is used to transmit control instructions, return monitoring pictures, etc., and for information security or cost reasons, enterprises do not deploy servers for IMS, so NW2 may not support IMS voice when used for production. The user is an employee of the enterprise, holding the enterprise-distributed UE. When a user is at home, the mobile phone distributed by enterprises works under NW1 as a common mobile phone, and voice is the most basic capability which needs to be ensured, so that the UE's user setting of the mobile phone is voice-center. When a user goes to work, the user enters a factory park, and the mobile phone distributed by an enterprise needs to be accessed to an enterprise private network NW2. However, NW2 is not voice-enabled, and the user does not know how to modify UE's user setting by AT command, so that the mobile UE distributed by the enterprise can never connect to the enterprise network NW2.

In the present situation that dynamic and convenient modification of UE's user setting cannot be realized, the present application provides a method for configuring user equipment. As shown in fig. 4, the method comprises the steps of:

s101: the user equipment sends indication information 01 to the access and mobility management function network element 01, and accordingly the access and mobility management function network element 01 receives the indication information 01 from the user equipment.

Wherein, the indication information 01 is used for indicating that the user equipment is centered on voice. For example, the indication information 01 may be UE's user setting set to (or take a value of) voice-center, or may be other information capable of indicating that the user equipment is currently voice-centered, and the embodiment of the application does not limit the form of the indication information 01, and any information that allows the access and mobility management function network element 01 to know that the user equipment is voice-centered may be understood as the indication information 01 in the embodiment of the application.

In one example, the user equipment sends a registration request message to the access and mobility management function network element 01, the registration request message including indication information 01. That is, the user equipment may indicate to the access and mobility management function network element 01 in the registration procedure that the user equipment is voice-centric.

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

In one example, when the core network device is an 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 indication information 01, if not, namely, the configuration stored in the network by the user equipment is centered on the data, the unified data management network element 01 sends indication information 02 to the access and mobile management function network element 01, and the indication information 02 indicates that the configuration of the user equipment in the network is centered on the data. The indication information 02 may be UE's usage setting set as data-center, or information indicating that UE's usage setting configured in the network by the UE is different from that configured in the UE, and the embodiment of the application does not limit the form of the indication information 02, and any information that the access and mobility management function network element 01 knows that the UE is configured in the network with data as center can be understood as the indication information 02 in the embodiment of the application. Accordingly, the access and mobility management function network element 01 determines, according to the indication information 02, that the configuration of the user equipment in the network is data-centric.

In another example, when the core network device is an access and mobility management function network element 01, the access and mobility management function network element 01 sends an existing message, such as a subscription data management (subscriber data management, SDM) get message, to the unified data management network element 01. After receiving the message, the unified data management network element 01 sends the UE's use setting set as data-center 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 indication information 01 according to the UE's user setting set as data-center from the unified data management network element 01, and if the configuration is inconsistent, the configuration of the user equipment in the network can be regarded as being determined to be centered on data.

In yet another example, when the core network device is a unified data management network element 01, the unified data management network element 01 receives the indication information 01 from the user device through the access and mobility management function network element 01, i.e. the access and mobility management function network element 01 forwards the indication information 01 from the user device 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 centered on data according to the UE's user setting of the user equipment in the network, which is stored locally or in UDR.

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

Wherein the indication information 03 is used to indicate that the user equipment is set to be data centric or to indicate that the checking of whether the network supports IMS is skipped.

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 use setting set to be 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 inconsistency of the UE's usage setting in the user equipment with in the user equipment in the network. The form of the indication information 03 is not limited in this embodiment, and any information that allows the ue to learn to set itself to be data-centric may be understood as the indication information 03 in this embodiment of the present application.

When the indication information 03 is used to indicate that the checking of whether the network supports IMS is skipped, the indication information 03 may be UE's use setting set to data-center, or may be other information indicating that the user equipment skips the checking of whether the network supports IMS. The form of the indication information 03 is not limited in the embodiment of the present application, and any information that allows the ue to know whether to skip checking whether the network supports IMS may be understood as the indication information 03 in the embodiment of the present application.

In one example, if the core network device is an access and mobility management function network element 01, the access and mobility management function network element 01 may send a registration accept message to the user equipment, where the registration accept message includes indication information 03; or the access and mobility management function network element 01 sends a configuration update command (configuration update command, CUC) message to the user equipment, the configuration update command message comprising the indication information 03. The configuration update command message is used for the network to issue parameters to the UE, i.e. for modifying or configuring parameters on the UE.

In another example, if the core network device is a unified data management network element 01, the unified data management network element 01 may send a user parameter update container (user parameters update (UPU) container) to the user device, where the user parameter update container includes the indication information 03; or the unified data management network element 01 may send a roaming diversion (Steering of roaming, SOR) container to the user equipment, the roaming diversion container comprising the indication information 03. The user parameter update container may be included in a message sent by the network to the user equipment, for example, a registration accept message, or a non-access stratum (NAS) transport message (NAS transport message).

It should be noted that, when the instruction information 03 is used to instruct setting the user equipment to be data-centric, the following S104a-S108a are performed; when the indication information 03 is used to indicate that the checking of whether the network supports IMS is skipped, S104b to S105b described below are performed.

S104a: the user equipment sets itself to be data-centric according to the indication information 03.

Specifically, the UE may update the stored UE's user setting from voice-center to data-center according to the indication information 03, or update the stored UE's user setting to a value different from the previous value; or the user equipment can delete the UE's user setting of the voice-center stored before according to the indication information 03, and reserve the UE's user setting of the data-center; or the UE may mark the UE's user setting of the previously saved voice-center as invalid, reserve the UE's user setting of the data-center, or mark the UE's user setting of the data-center as valid according to the indication information 03.

And in the mode of S101-S104a, according to the stored UE ' S user setting in the network, the UE is instructed to modify the UE ' S user setting so as to dynamically and conveniently modify the UE ' S user setting.

It will be appreciated that in one example, the network (e.g., NW2 in fig. 3) where the access and mobility management function network element 01 and the unified data management network element 01 are located does not support IMS, and thus the configuration maintained by the user equipment at that network is data-central. In order to enable the voice-centric user equipment to access the network, the configuration stored in the user equipment itself needs to be modified into data-center, and the S101-S104a is executed, so that the purpose can be achieved.

However, when the user equipment moves from a non-IMS-enabled network to an IMS-enabled network (e.g., NW1 in fig. 3), the user equipment may be modified from data-center to voice-center by performing S105a-S108 a.

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

The indication information 04 is used for indicating that the user equipment is centered on the data. Regarding the indication information 04, reference may be made to the description of the indication information 01 in S101, except that the indication information 01 indicates that the user equipment is voice-centered, and the indication information 04 indicates that the user equipment is data-centered.

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

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

In one example, when the core network device is an 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 indication information 04, and if not, that is, the configuration stored in the network by the user equipment is centered on voice, the unified data management network element 02 sends the indication information 05 to the access and mobility management function network element 02, and the indication information 05 indicates that the configuration of the user equipment in the network is centered on voice. The description of the indication information 05 in S102 may be referred to for the indication information 02, where the difference is that the indication information 05 indicates that the configuration of the user equipment in the network is voice-centric, and the indication information 02 indicates that the configuration of the user equipment in the network is data-centric.

In another example, when the core network device is an access as access and mobility management function network element 02, the access and mobility management function network element 02 sends an existing message, such as a subscription data management get (sdm_get) message, to the unified data management network element 02. After receiving the message, the unified data management network element 02 sends a UE's use setting set to voice-center 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 indication information 04 according to the UE's user setting set as voice-center from the unified data management network element 02, and if the configuration is inconsistent, the configuration of the user equipment in the network is determined to be centered on voice.

In yet another example, when the core network device is a unified data management network element 02, the unified data management network element 02 receives the indication information 04 from the user device through the access and mobility management function network element 02, i.e. the access and mobility management function network element 02 forwards the indication information 04 from the user device 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 user setting of the user equipment in the network, which is stored locally or in UDR.

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

Wherein the indication information 06 is used for indicating that the user equipment is set to be centered on voice. Regarding the indication information 06, reference may be made to the description of the indication information 03 in S103, except that the indication information 06 indicates that the user equipment is set to be voice-centered, and the indication information 03 indicates that the user equipment is set to be data-centered.

In one example, if the core network device is the access and mobility management function network element 02, the access and mobility management function network element 02 may send a registration accept message to the user equipment, where the registration accept message includes the indication information 06; or the access and mobility management function network element 02 sends a configuration update command message to the user equipment, the configuration update command message comprising the indication information 06.

In another example, if the core network device is the unified data management network element 02, the unified data management network element 02 may send a user parameter update container to the user device, where the user parameter update container includes indication information 06; or the unified data management network element 02 may send a roaming diversion container to the user equipment, the roaming diversion container comprising the indication information 06.

S108a: the user equipment sets itself to be voice-centered according to the indication information 06.

Specifically, how the user device sets itself to be voice-centered according to the instruction information 06 can refer to the description in S104a, except that the user device sets itself to be data-centered in S108a and sets itself to be data-centered in S104 a.

It should be noted that S105a to 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 an IMS-enabled network.

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

In one example, the user equipment receives a registration accept message from the access and mobility management function network element 01, the registration accept message including information indicating 03 and information indicating whether the network supports IMS. The information indicating whether the network supports IMS may be, for example, IMS-over-PS (packet switched), indicating that the network does not support IMS when IMS-over-PS is not supported, and indicating that the network supports IMS when IMS-over-PS is supported. The user equipment receives the registration acceptance message and ignores the check of the content of the information indicating whether the network supports IMS according to the indication information 03.

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

It should be noted that, the indication information 03 may be replaced by an indication to skip checking of UE's usage in the UE, that is, after the UE receives the indication information 03, the UE may not check the usage setting of the UE itself, that is, may not perform an action of matching with the network, and may access the network by default.

S105b: the user equipment accesses the network.

In one example, the user equipment access network is configured to send a service request message to the access and mobility management function network element 01, or to send a session establishment request message, e.g. a protocol data unit (protocol data unit, PDU), session establishment request to the session management network element via the access and mobility management function network element 01.

It can be appreciated that since the user equipment skips checking whether the network supports IMS, the user equipment of the voice-center can access the network to obtain data services even if the network does not support IMS.

Another method of configuring a user equipment is provided. As shown in fig. 5, the method comprises the steps of:

s201: the access network device sends the identification information of the first network to the user device, and accordingly, the user device receives the identification information of the first network from the access network device.

In one example, before receiving the identification information of the first network, the correspondence between the identification information of one or more networks and UE's usage setting is preconfigured in the user equipment, that is, the identification information of one network may correspond to one or two UE's usage setting. The network identification information may be an Identification (ID) of the public land mobile network Public Land Mobile Network (PLMN) and/or an identification (slice ID) of the slice and/or a tracking area identification (tracking area identity, TAI). For example, when the identification information of the network is PLMN ID, the correspondence may be:

{

PLMN ID1--UE usage＝“voice-centric”；

PLMN ID2--UE usage＝“data-centric”；

……

-a }; when the identification information of the network is PLMN ID, slice ID and TAI, the correspondence may 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 one example, an access network device sends a system message to a user device, the system message including identification information of a first network. Optionally, the system message may further comprise information indicating whether the first network supports IMS (this information is for example IMS-capability).

S202: the user equipment determines to set the user equipment to be centered on voice or centered on data according to the identification information of the first network and the corresponding relation between the identification information of one or more networks and the use setting of the user equipment.

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

In one example, when the user equipment also receives 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 the UE's use setting. The method specifically comprises the following steps: UE's usage= "voice-center" and IMS-capability= "supported", matching was successful; UE's use= "voice-center" and IMS-capability= "not-supported", matching failed; UE's usage= "data-center" and IMS-capability= "supported", matching was successful; UE's usage= "data-center" and IMS-capability= "not-supported", match successful. Wherein, successful matching means that the user equipment can access the first network, and failure of matching means that the user equipment does not access the first network.

It can be understood that, by pre-configuring the correspondence in the UE, indicating the UE usage setting that needs to be adopted by the UE in different PLMNs/slices/TAIs, dynamic and convenient modification of the UE's usage setting can be achieved.

Based on the method shown in fig. 4, the present application provides another method for configuring a user equipment. As shown in fig. 6, in the method, the access and mobility management function network element is AMF, and the unified data management network element is UDM, and the method includes the following steps:

s301: the UE sends a registration request message to the AMF, and accordingly, the AMF receives the registration request message from the UE.

Wherein the registration request message includes a UE's use setting cell (information element, IE). According to the current protocol specification, the UE with voice-center capability carries the IE in the registration request message. The UE capability can be known from the presence or absence of this IE in the message. In addition, the specific value of the IE may be either voice-center or data-center, indicating the current UE's usage setting of the UE.

S302: if the network supports IMS, S303 is performed, and if not, S304 is performed.

S303: the network replies with a registration accept message to the UE and indicates that the network supports IMS voice.

S304: the initiation determination is performed only if the registration request message in S301 includes UE 'S usage setting IE (i.e., the UE is voice-capable), the UE' S usage setting IE value is voice-center (i.e., the UE is currently voice-centric), the network is IMS-unsupported, all three of which are satisfied, S305 is performed, otherwise S306b or S306c is performed.

S305: the AMF queries the UDM located in the HPLMN for the configured UE's use setting (not excluding other names) of the UE configured in the network.

The specific query mode can be any one of the following three modes:

mode 1: the AMF sends the current UE ' S user setting (i.e. included in the registration request message in S301) to the UDM, the UDM checks whether the UE ' S user setting is consistent with the configured UE ' S user setting, and when the UE ' S user setting is inconsistent, the UDM returns the configured UE ' S user setting to the AMF.

Mode 2: the AMF sends the current UE 'S user setting (i.e. included in the registration request message in S301) to the UDM, which checks whether the UE' S user setting is consistent with the configured UE 'S user setting, and when not, the UDM returns an indication information (indicator) 07 to the AMF indicating that the UE' S user setting on the current UE is inconsistent with the configured value.

Mode 3: the message sent by the AMF to the UDM is the current standard message without new content, and the UDM sends configured UE's user setting to the AMF in the return message, and the AMF checks whether the UE's user setting is consistent with the configured UE's user setting.

S306a and S307 are performed when the UE 'S usage setting does not coincide with the configured UE' S usage setting, otherwise S306b or S306c are performed.

S306a: the network replies to the UE with a registration accept message comprising 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. indicating that the current UE's user setting value of the UE is inconsistent with the configured UE's user setting value, the UE needs to modify the current UE's user setting = voice-center to data-center if it is.

2. The UE is instructed to initiate/not initiate a UE's usage setting check.

Optionally, the registration accept message further comprises information indicating that the network is IMS voice unsupported, e.g. the information is IMS-over-ps=not-supported.

S307: the UE modifies the UE 'S usage setting value or starts/does not start the UE' S usage setting check according to the registration accept message in S306 a.

The checking means that before the UE makes service, the UE needs to see whether the network is matched or not according to the capability of the network and the configuration of the UE. The self-contained configuration is voice-central, and the network is IMS-enabled, then this is called matching. Only if matching is performed, the service can be executed, and the network of the UE needs to be changed without matching.

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

Alternatively, activating/deactivating the UE's use setting check may also be referred to as not ignoring/ignoring or not skipping/skipping the UE's use setting check.

S306b: the network replies with a registration accept message to the UE and indicates that the network does not support IMS voice.

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

It should be noted that the AMF in the method may be replaced by an MME in the 4G network or another network element with a similar function in the future network, and the UDM may be replaced by a UDR or another network element with a similar function in the future network.

According to the method, the network can refresh the UE's user equipment on the UE through the registration acceptance message or indicate whether the UE considers the UE's user equipment, so that the UE's user equipment is dynamically and conveniently modified.

Based on the method shown in fig. 4, the present application provides another method for configuring a user equipment. As shown in fig. 7, in the method, the access and mobility management function network element is AMF, and the unified data management network element is UDM, and the method includes the following steps:

s401: the UE sends a registration request message to the AMF, and accordingly, the AMF receives the registration request message from the UE.

Wherein the registration request message includes UE's usage setting IE. According to the current protocol, the UE with voice-center capability carries the IE in the registration request message. The UE capability can be known from the presence or absence of this IE in the message. The specific value of the IE may be either voice-center or data-center, indicating the current UE's usage setting of the UE.

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

S403: the initiation determination is performed S404 only if the registration request message of S401 includes UE 'S usage setting IE (i.e., the UE is voice-capable), the value of UE' S usage setting IE is voice-center (i.e., the UE is currently configured to be voice-centric), and the network is IMS-unsupported, i.e., all three are satisfied.

S404: referring to S305, the AMF queries the UE configured UE ' S use setting to UDM, and performs S405 and S406 only when the UE ' S use setting in S401 is inconsistent with the configured UE ' S use setting.

S405: the network sends a Configuration Update Command (CUC) message to the UE, the message including configured UE's use setting and/or indication information 08, wherein the indication information 08 may have at least one of the following meanings:

2. The UE is instructed to initiate/not initiate a UE's usage setting check.

The CUC message is a non-access stratum (NAS) message in a user parameter update (User parameters update, UCU) procedure, and is used for the network to issue parameters to the UE, that is, to modify or configure parameters on the UE.

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

According to the method, the UE firstly registers to one PLMN according to the existing standard rule and executes a registration process, and after the registration process, the network refreshes the UE's user setting through a UCU process if required.

Based on the method shown in fig. 4, the present application provides another method for configuring a user equipment. As shown in fig. 8, in the method, the access and mobility management function network element is AMF, and the unified data management network element is UDM, and the method includes the following steps:

s501: the UE sends a registration request message to the AMF, and accordingly, the AMF receives the registration request message from the UE.

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

S503: the decision is initiated and S504 is performed only if the registration request message of S501 includes UE 'S usage setting IE (i.e. the UE is voice-capable), the UE' S usage setting IE parameter value is voice-centric (i.e. the UE is currently configured voice-centric), and the network is IMS-not supported, i.e. all three are satisfied.

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

S505: the UDM judges whether the received UE 'S usage setting is identical to the UE configured UE' S usage setting, and if not, performs 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 User parameters update container carries configured UE's use setting and/or indication information 2.

Wherein the indication information 2 may have at least one of the following meanings:

1. the current UE's user setting value of the UE is inconsistent with the configured UE's user setting value, and if the current UE's user setting=voice-center, the UE needs to modify the current UE's user setting value into data-center;

2. the UE is instructed to activate/deactivate/ignore/not ignore/skip/not skip the UE's usage setting check.

S507a: the UE modifies the UE 'S usage setting value according to the UPU container in S506a, or starts/does not start/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, wherein the SOR container carries PLMN list;

S507b: the UE switches the PLMN currently located according to the PLMN list in S506 b.

Specifically, the UE may search sequentially according to the PLMNs included in the PLMN list from high to low priority, so as to switch from the PLMN currently located to the PLMN in the PLMN list.

According to the method, the UE is firstly registered on one PLMN according to the existing standard rule and executes a registration flow, and then the network refreshes the UE's service setting through the UPU flow or instructs the UE to migrate to other PLMNs through the SOR flow.

Based on the method shown in fig. 5, the present application provides another method for configuring a user equipment. As shown in fig. 9, the method comprises the steps of:

s601: the HPLMN pre-configures a list for the UE that includes the UE's usage setting value that the UE needs to take in a certain PLMN and/or slice and/or TAI list.

The list may be stored on the SIM card or may be stored 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 identity of a PLMN and/or the identity of a slice and/or the TAI.

In one example, the base station also broadcasts information whether the network supports IMS voice. The information whether the network supports IMS voice may be included in a system message (system info). It will be appreciated that this information is currently signalled to the UE by the network in a registration procedure via a registration accept or reject message, but in the present embodiment this information is included in the system message to be broadcast.

S603: in the current PLMN selection process, the UE needs to consider the list preconfigured in S601 and the information in the system message in S602 to select a successfully matched PLMN.

The specific matching rule may be:

UE usage= "voice-center" and IMS-capability= "supported" in system message, matching is successful;

UE usage= "voice-center" and IMS-capability= "not-supported" in system message, matching failed;

UE usage= "data-center" and IMS-capability= "supported" in system message, matching is successful;

UE usage= "data-center" and IMS-capability= "not-supported" in system message, matching was successful.

By the method, a list is preconfigured on the UE, and the UE's usage setting which is needed to be used by the UE in different PLMN/slice/TAI lists is indicated. In addition, the system information of the base station can be expanded, and whether the core network supports IMS or not is broadcasted. And the UE selects a proper network according to the preconfigured list and the system message, so that the adaptation of the UE's user setting in different networks is realized.

Fig. 10 and 11 are schematic structural diagrams of a communication device provided in the present application. These communication devices may be used to implement the functions of the user equipment (UE, for example, hereinafter), the access and mobility management function network element (AMF, for example, hereinafter), or the unified data management network element (UDM, for example, hereinafter) in the above method embodiments, so that the beneficial effects of the above method embodiments may also be implemented. In the embodiment of the present application, the communication device may be a UE, an AMF or a UDM, or may be a module (e.g. a chip) applied to the UE, the AMF or the UDM.

As shown in fig. 10, the communication apparatus 1000 includes a processing unit 1010 and a transceiver unit 1020. The communication device 1000 is configured to implement the functions of UE, AMF or UDM in the above-described method embodiments.

In one example, when the communication device is a UE and is configured to implement the method embodiment corresponding to fig. 4, the transceiver unit 1020 is configured to send first indication information to the first access and mobility management function network element and receive second indication information, where the first indication information is used to indicate that the user equipment is centered on voice; the processing unit 1010 is configured to set the user equipment to be data-centric according to the second indication information.

As a possible implementation method, the transceiver unit 1020 is configured to send a registration request message to the first access and mobility management function network element, where the registration request message includes the first indication information.
