The following related technologies can be optionally combined with the technical solutions of the embodiments of the present application, and they all belong to the embodiments of the present application. protected range.
5G***中引入了网络切片(Network Slicing)的全新特性，该特性也是5G***的一个代表性功能。它的目的是在同一个网络环境下通过划分不同的网络切片，分别分配不同的网络资源，如带宽、速率、业务质量等，从而使不同的业务需求可以更合理地占用网络资源。The 5G system introduces the new feature of network slicing, which is also a representative function of the 5G system. Its purpose is to divide different network slices in the same network environment and allocate different network resources, such as bandwidth, speed, service quality, etc., so that different business needs can occupy network resources more reasonably.
当一个UE在某个公共陆地移动网(PLMN，public land mobile network)发起注册时，UE需要根据自身保存的该网络下的可用切片信息(如可用的网络切片选择辅助信息(Allowed NSSAI，Allowed Network Slice Selection Assistance Information))及配置的切片信息(如配置的NSSAI(Configured NSSAI))，或缺省配置的切片信息(如缺省配置的NSSAI(Default Configured NSSAI))，排除掉其中被拒绝的切片信息(如拒绝的NSSAI(Rejected NSSAI))，并结合UE自身策略，在注册请求的非接入层(NAS，Non-Access-Stratum)消息(如注册请求(Registration Request))中携带UE请求的切片信息(如请求的NSSAI(Requested NSSAI))给网络。网络根据其请求的切片信息，确认此UE在当前网络下的配置切片信息(如配置的NSSAI)、可用切片信息(如可用的NSSAI)以及拒绝切片信息(如拒绝的NSSAI)，并在注册响应的NAS消息(如请求响应(Registration Accept))中，将这些信息配置给UE。上述这些NSSAI中均可以包含一个或多个单一网络切片选择辅助信息(S-NSSAI，Single NSSAI)。之后UE即可根据这些配置信息和自身策略，选择特定的当前网络下可用的S-NSSAI来发起数据会话。When a UE initiates registration in a public land mobile network (PLMN, public land mobile network), the UE needs to save the available slice information under the network (such as the available network slice selection auxiliary information (Allowed NSSAI, Allowed Network Slice Selection Assistance Information)) and configured slice information (such as configured NSSAI (Configured NSSAI)), or default configured slice information (such as default configured NSSAI (Default Configured NSSAI)), exclude the rejected slices Information (such as rejected NSSAI (Rejected NSSAI)), combined with the UE's own policy, carries the UE requested information in the non-access layer (NAS, Non-Access-Stratum) message (such as registration request (Registration Request)) of the registration request. Slice information (such as requested NSSAI (Requested NSSAI)) to the network. The network confirms the configured slicing information (such as configured NSSAI), available slicing information (such as available NSSAI), and rejected slicing information (such as rejected NSSAI) of the UE under the current network based on the requested slicing information, and responds in the registration response Configure this information to the UE in the NAS message (such as request response (Registration Accept)). Each of the above NSSAI can contain one or more single network slice selection auxiliary information (S-NSSAI, Single NSSAI). The UE can then select a specific S-NSSAI available in the current network to initiate a data session based on these configuration information and its own policies.
在此基础之上，引入了一个新的概念，即网络切片并发注册组(Network Slice Simultaneous Registration Group，NSSRG)。当用户在注册请求中指明终端支持NSSRG功能时，网络在注册响应中会给出NSSRG配置信息。On this basis, a new concept is introduced, namely Network Slice Simultaneous Registration Group (NSSRG). When the user indicates in the registration request that the terminal supports the NSSRG function, the network will provide the NSSRG configuration information in the registration response.
协议中对该信息定义如表1：

This information is defined in the protocol as shown in Table 1:

表1-NSSRG配置信息定义Table 1-NSSRG configuration information definition
如表1所示，NSSRG信息中可以包含一个或多个S-NSSAI关联NSSRG值(NSSRG values for S-NSSAI)，该信息在协议中进一步定义如表2：
As shown in Table 1, the NSSRG information can contain one or more S-NSSAI associated NSSRG values (NSSRG values for S-NSSAI). This information is further defined in the protocol as shown in Table 2:
表2-S-NSSAI关联NSSRG值定义Table 2-S-NSSAI associated NSSRG value definition
可以看到，一个S-NSSAI可以关联一个或多个NSSRG值，以此来表明一个S-NSSAI关联到哪些NSSRG中。It can be seen that an S-NSSAI can be associated with one or more NSSRG values to indicate which NSSRGs an S-NSSAI is associated with.
NSSRG信息是与当前网络下的配置切片(Configured NSSAI)相关联的，也就是说，所有当前网络下配置的S-NSSAI，每一个都可以关联一个或多个NSSRG。而可用切片(如可用的NSSAI)是当前网络下配置切片的子集，所以每一个可用S-NSSAI也就关联着一个或多个NSSRG。NSSRG information is associated with the configuration slice (Configured NSSAI) under the current network. That is to say, all S-NSSAI configured under the current network can each be associated with one or more NSSRGs. The available slices (such as available NSSAI) are a subset of the slices configured in the current network, so each available S-NSSAI is associated with one or more NSSRGs.
用户发起注册时请求的切片一般关联同一个NSSRG，因此网络侧在每次注册成功后，分配给用户的可用切片会关联共同的NSSRG，用户发起的每一个数据会话，也就可以关联到具体的某个NSSRG。使用NSSRG可以实现对用户的切片配置进行分类管理，可以基于具体的实现策略，确认用户可以在特定NSSRG上使用哪些相关联的切片，然后配置对应的可用切片(如Allowed NSSAI)给用户，用户后续就只能在相应的关联NSSRG上发起数据会话。不同用户根据其签约信息的不同，也就只能使用自己可用的NSSRG关联的可用切片，而不会访问关联其它NSSRG的切片，从而实现了网络切片的进一步精细化管理。The slices requested when a user initiates registration are generally associated with the same NSSRG. Therefore, after each successful registration on the network side, the available slices assigned to the user will be associated with the same NSSRG. Each data session initiated by the user can also be associated with a specific NSSRG. Some NSSRG. NSSRG can be used to classify and manage users' slice configurations. Based on specific implementation strategies, users can confirm which associated slices they can use on a specific NSSRG, and then configure the corresponding available slices (such as Allowed NSSAI) to the user. The user can then follow up Data sessions can only be initiated on the corresponding associated NSSRG. Different users can only use the available slices associated with their own available NSSRGs based on their different subscription information, and will not access slices associated with other NSSRGs, thus achieving further refined management of network slices.
现有切片请求过程的主要缺点在于以下场景：The main drawback of the existing tile request process lies in the following scenarios:
当前的拒绝切片定义，依然是基于S-NSSAI的，也就是说，只能按具体的S-NSSAI来拒绝切片请求。如果一个S-NSSAI关联了多个NSSRG，网络在当前协议框架内对其拒绝时，不能基于NSSRG来拒绝。The current slicing rejection definition is still based on S-NSSAI, that is to say, slicing requests can only be rejected based on specific S-NSSAI. If an S-NSSAI is associated with multiple NSSRGs and the network rejects it within the current protocol framework, it cannot be rejected based on the NSSRGs.
举例来说，比如一个用户签约了两个NSSRG：组1和组2，当前终端注册时是在组1上请求切片，在组2上未请求；如果请求的S-NSSAI同时关联了组1和组2，网络侧在拒 绝该切片请求时，会将S-NSSAI一律拒绝，这就导致最终用户在组2上可用的切片也一并被拒绝。后续如果用户切换到组2，重新发起注册并请求切片时，其请求的组2上的S-NSSAI会排除掉之前被拒绝的S-NSSAI，因此组2上当前请求的切片个数，就要小于组2实际可请求切片个数，即之前在组1上发起切片请求时拒绝的S-NSSAI在组2上不可以被请求。可见，现有的请求和拒绝切片是以S-NSSAI为单位来实现的，实际上并未做到基于NSSRG的切片精细管理。For example, if a user subscribes to two NSSRGs: Group 1 and Group 2, the current terminal requests slices on Group 1 when registering, but not on Group 2; if the requested S-NSSAI is associated with both Group 1 and Group 2, Group 2, the network side is rejecting When rejecting the slice request, S-NSSAI will be rejected, which will cause the slices available to the end user on group 2 to also be rejected. If the user subsequently switches to group 2, re-initiates registration and requests slices, the S-NSSAI requested in group 2 will exclude the previously rejected S-NSSAI, so the number of slices currently requested in group 2 will be The number of slices that can actually be requested by group 2 is less than the number, that is, the S-NSSAI that was previously rejected when initiating a slice request on group 1 cannot be requested on group 2. It can be seen that the existing request and reject slices are implemented in units of S-NSSAI, and in fact, fine management of slices based on NSSRG is not achieved.
图2是根据本申请一实施例的切片请求方法200的示意性流程图。该方法可选地可以应用于图1所示的***，但并不仅限于此。该方法包括以下内容的至少部分内容。Figure 2 is a schematic flowchart of a slice request method 200 according to an embodiment of the present application. This method can optionally be applied to the system shown in Figure 1, but is not limited thereto. The method includes at least part of the following.
S210、终端设备根据基于网络切片并发注册组的拒绝切片信息，请求网络切片。S210. The terminal device requests network slicing based on the slicing rejection information based on the network slicing concurrent registration group.
通过根据基于NSSRG的拒绝切片信息请求网络切片，本申请实施例能够实现基于NSSRG精确管理和请求网络切片。By requesting network slicing based on NSSRG-based rejection slicing information, embodiments of the present application can implement precise management and requesting network slicing based on NSSRG.
基于NSSRG的拒绝切片信息可以由网络侧配置，例如由AMF配置。The NSSRG-based rejection slice information can be configured by the network side, for example, by the AMF.
在一些实施方式中，基于NSSRG的拒绝切片信息在扩展拒绝切片信息中携带。例如，扩展拒绝切片信息可以为扩展拒绝网络切片选择辅助信息(Extended Rejected NSSAI)。In some embodiments, NSSRG-based reject slice information is carried in extended reject slice information. For example, extended rejected slice information can select auxiliary information (Extended Rejected NSSAI) for extended rejected network slices.
扩展拒绝网络切片选择辅助信息的格式如表3所示：
The format of the extended rejection network slice selection auxiliary information is shown in Table 3:
表3-扩展拒绝NSSAITable 3 - Extended Denial NSSAI
扩展拒绝切片信息(如扩展拒绝NSSAI)中可以携带一个或多个基于NSSRG的拒绝切片信息，其中，基于NSSRG的拒绝切片信息可以为基于NSSRG的S-NSSAI。The extended deny slice information (such as extended deny NSSAI) may carry one or more NSSRG-based deny slice information, where the NSSRG-based deny slice information may be NSSRG-based S-NSSAI.
在一些实施方式中，携带一个或多个基于NSSRG的切片拒绝信息的扩展拒绝S-NSSAI如表4所示：

In some embodiments, the extended deny S-NSSAI carrying one or more NSSRG-based slice deny information is shown in Table 4:

表4Table 4
在一些实施方式中，表4所示的扩展拒绝NSSAI的列表类型(Type of list)的值为第一值，用于表示该扩展拒绝NSSAI是携带基于NSSRG的拒绝切片信息的扩展拒绝NSSAI。在相关技术中，已经定义了两种类型的扩展拒绝NSSAI，其中一种是拒绝S-NSSAI的列表，其列表类型(Type of list)的值为000；另一种是增加了回退定时器时长的扩展拒绝NSSAI，其列表类型(Type of list)的值为001。为了与已有的扩展拒绝NSSAI区分，本申请实施例提出的携带基于NSSRG的拒绝切片信息的扩展拒绝NSSAI中，列表类型(Type of list)的值(即上述第一值)可以为除前述000和001以外的值，例如第一值为010。In some embodiments, the value of the list type (Type of list) of the extended deny NSSAI shown in Table 4 is the first value, which is used to indicate that the extended deny NSSAI is an extended deny NSSAI that carries NSSRG-based deny slice information. In related technology, two types of extended rejection NSSAI have been defined, one of which is a list of rejection S-NSSAI, the value of its list type (Type of list) is 000; the other is to add a backoff timer The duration extension rejects NSSAI, whose Type of list value is 001. In order to distinguish it from the existing extended deny NSSAI, in the extended deny NSSAI carrying NSSRG-based deny slice information proposed by the embodiment of the present application, the value of the list type (Type of list) (i.e., the above-mentioned first value) can be other than the aforementioned 000 and a value other than 001, for example, the first value is 010.
如表4所示，本申请实施例提出的扩展拒绝NSSAI中携带一个或多个基于NSSRG的拒绝S-NSSAI(Rejected S-NSSAI with NSSRG)。以表4中基于NSSRG的拒绝S-NSSAI 1(Rejected S-NSSAI 1 with NSSRG)为例，在一些实施方式中，其内容如表5所示：
As shown in Table 4, the extended rejected NSSAI proposed in the embodiment of this application carries one or more rejected S-NSSAI based on NSSRG (Rejected S-NSSAI with NSSRG). Taking Rejected S-NSSAI 1 with NSSRG in Table 4 as an example, in some implementations, its content is as shown in Table 5:
表5table 5
如表5所示，表5中包含S-NSSAI 1与多个NSSRG值的信息，表示S-NSSAI 1在关联NSSRG 1、关联NSSRG 2、…或关联NSSRG y的情况下被拒绝。可见，本申请实施例采用基于NSSRG的拒绝切片信息，可以实现依据S-NSSAI和NSSRG的组合信息对网络切片进行精确管理。例如，S-NSSAI A关联NSSRG 1和NSSRG 2；终端设备在NSSRG 1上请求S-NSSAI A时，被网络设备拒绝，终端设备接收并保存网络设备发送的基于NSSRG的拒绝切片信息，该基于NSSRG的拒绝切片信息中包括S-NSSAI A和NSSRG 1的信息；之后，终端设备切换到NSSRG 2时，重新发起注册请求，由于基于NSSRG的拒绝切片信息中只包含S-NSSAI A和NSSRG 1的信息、而并未包含S-NSSAI A和NSSRG 2的信息，因此终端设备可以在NSSRG 2上请求该S-NSSAI A。可见，本申请实施例有利于精确控制NSSRG相关联的网络切片。As shown in Table 5, Table 5 contains information about S-NSSAI 1 and multiple NSSRG values, indicating that S-NSSAI 1 is rejected when associated with NSSRG 1, associated with NSSRG 2, ... or associated with NSSRG y. It can be seen that the embodiments of the present application use NSSRG-based rejection of slice information, which can achieve accurate management of network slices based on the combined information of S-NSSAI and NSSRG. For example, S-NSSAI A is associated with NSSRG 1 and NSSRG 2; when the terminal device requests S-NSSAI A on NSSRG 1, it is rejected by the network device. The terminal device receives and saves the NSSRG-based rejection slicing information sent by the network device. The NSSRG-based rejection slicing information is sent by the network device. The rejected slice information includes the information of S-NSSAI A and NSSRG 1; later, when the terminal device switches to NSSRG 2, it re-initiates the registration request, because the rejected slice information based on NSSRG only contains the information of S-NSSAI A and NSSRG 1. , but does not contain the information of S-NSSAI A and NSSRG 2, so the terminal device can request the S-NSSAI A on NSSRG 2. It can be seen that the embodiments of the present application are beneficial to accurately controlling the network slice associated with the NSSRG.
在一些实施方式中，本申请实施例提出的切片请求方法还包括：终端设备并记录基于 NSSRG的拒绝切片信息。In some implementations, the slice request method proposed in the embodiment of this application also includes: a terminal device and recording based on Rejection slicing information for NSSRG.
其中，基于NSSRG的拒绝切片信息可以由网络设备(如AMF)通过注册响应(Registration Accept)或配置更新命令(Configuration Update Command)发送，例如，终端设备接收注册响应或配置更新命令，该注册响应或配置更新命令携带该基于NSSRG的拒绝切片信息。Among them, the NSSRG-based rejection slicing information can be sent by the network device (such as AMF) through the registration response (Registration Accept) or the configuration update command (Configuration Update Command). For example, the terminal device receives the registration response or the configuration update command, and the registration response or The configuration update command carries the NSSRG-based rejection slicing information.
在接收到基于NSSRG的拒绝切片信息之后，终端设备可以对之前保存的可用的NSSAI进行更新，例如，终端设备将第一S-NSSAI从可用NSSAI中删除；其中，第一S-NSSAI为关联第一NSSRG的S-NSSAI，并且该基于NSSRG的拒绝切片信息中包含该第一S-NSSAI和该第一NSSRG的信息。其中，该第一NSSRG可以是UE当前请求的NSSRG。具体地，终端设备收到基于NSSRG的拒绝切片信息后，可以检查当前的每一个Allowed S-NSSAI(在可用NSSAI中)、及其当前关联的NSSRG组是否已经被拒绝。如果是，则将该Allowed S-NSSAI从Allowed NSSAI中删除。如果该S-NSSAI已经关联有激活的PDU会话(PDU Session)，可以先释放该PDU session，之后再删除该S-NSSAI。After receiving the NSSRG-based rejection slicing information, the terminal device can update the previously saved available NSSAI. For example, the terminal device deletes the first S-NSSAI from the available NSSAI; where the first S-NSSAI is associated with the third S-NSSAI. The S-NSSAI of an NSSRG, and the NSSRG-based rejection slice information includes the information of the first S-NSSAI and the first NSSRG. The first NSSRG may be the NSSRG currently requested by the UE. Specifically, after receiving the NSSRG-based rejection slicing information, the terminal device can check whether each of the current Allowed S-NSSAI (in the available NSSAI) and its currently associated NSSRG group has been rejected. If so, delete the Allowed S-NSSAI from the Allowed NSSAI. If the S-NSSAI is already associated with an activated PDU session, you can release the PDU session first and then delete the S-NSSAI.
后续终端设备发起注册请求时，填写注册请求切片(Requested NSSAI)时，可以查看请求的S-NSSAI和所关联的NSSRG是否在基于NSSRG的拒绝切片列表中。如果是，则不可以请求此S-NSSAI，否则仍可请求。When a subsequent terminal device initiates a registration request and fills in the registration request slice (Requested NSSAI), you can check whether the requested S-NSSAI and the associated NSSRG are in the NSSRG-based rejection slice list. If so, this S-NSSAI MUST NOT be requested, otherwise it can still be requested.
具体地，终端设备根据基于NSSRG的拒绝切片信息，请求网络切片，可以包括：Specifically, the terminal device requests network slicing based on NSSRG-based rejection slicing information, which may include:
在基于NSSRG的拒绝切片信息中包含待请求的网络切片和第三NSSRG的信息的情况下，终端设备不请求关联第三NSSRG的待请求的网络切片；或者，In the case where the NSSRG-based rejection slice information contains information about the network slice to be requested and the third NSSRG, the terminal device does not request the network slice to be requested associated with the third NSSRG; or,
在基于NSSRG的拒绝切片信息中不包含待请求的网络切片和第三NSSRG的信息的情况下，终端设备请求关联第三NSSRG的待请求的网络切片。If the NSSRG-based rejection slice information does not include information about the network slice to be requested and the third NSSRG, the terminal device requests the network slice to be requested associated with the third NSSRG.
例如，在基于NSSRG的拒绝切片信息中包含待请求的S-NSSAI和第三NSSRG的信息的情况下，终端设备不请求关联该第三NSSRG的待请求的S-NSSAI；或者，For example, in the case where the NSSRG-based rejection slice information contains information about the S-NSSAI to be requested and the third NSSRG, the terminal device does not request the S-NSSAI to be requested associated with the third NSSRG; or,
在基于NSSRG的拒绝切片信息中不包含待请求的S-NSSAI和第三NSSRG的信息的情况下，终端设备请求关联该第三NSSRG的待请求的S-NSSAI。If the NSSRG-based rejection slice information does not contain the information of the S-NSSAI to be requested and the third NSSRG, the terminal device requests to associate the S-NSSAI to be requested of the third NSSRG.
在一些实施方式中，如果终端设备保存的可用NSSAI被清空，终端设备可以发起更新注册请求，并在更新注册请求中请求关联第二NSSRG的第二S-NSSAI，其中，基于NSSRG的拒绝切片信息中不包含该第二S-NSSAI和第二NSSRG的信息。也就是说，终端设备在某NSSRG上发起更新注册请求时，请求的S-NSSAI和该NSSRG的信息不包含在基于NSSRG的拒绝切片信息中。In some implementations, if the available NSSAI saved by the terminal device is cleared, the terminal device may initiate an update registration request, and request the second S-NSSAI associated with the second NSSRG in the update registration request, where the rejection slice information is based on the NSSRG. does not contain the information of the second S-NSSAI and the second NSSRG. That is to say, when the terminal device initiates an update registration request on a certain NSSRG, the requested S-NSSAI and the information of the NSSRG are not included in the NSSRG-based rejection slicing information.
网络设备(如AMF)应尽量保证终端设备在当前PLMN下至少有一个可用NSSRG组，并且有关联可用的切片。如果由于签约信息更改、人工管控等特殊原因，UE确实没有任何可用的NSSRG，则网络设备可以拒绝UE的注册请求，拒绝原因可以为-#7“5G业务不可用”。Network equipment (such as AMF) should try to ensure that the terminal equipment has at least one available NSSRG group under the current PLMN and has associated available slices. If the UE does not have any available NSSRG due to special reasons such as changes in subscription information or manual control, the network device can reject the UE's registration request, and the reason for rejection can be -#7 "5G service unavailable".
实施例1：Example 1:
图3是根据本申请实施例1的实现流程图，包括以下步骤：Figure 3 is an implementation flow chart according to Embodiment 1 of the present application, including the following steps:
S301、UE在当前PLMN下初次注册，此时UE没有当前PLMN下的可用切片(Allowed NSSAI)及配置切片(Configured NSSAI)记录，UE使用缺省配置切片(Default Configured NSSAI)作为请求切片(Requested NSSAI)发起注册请求。S301. The UE registers under the current PLMN for the first time. At this time, the UE does not have available slices (Allowed NSSAI) and configured slices (Configured NSSAI) records under the current PLMN. The UE uses the default configured slice (Default Configured NSSAI) as the requested slice (Requested NSSAI). ) initiates a registration request.
S302、AMF在注册响应(Registration Accept)中下发可用切片(Allowed NSSAI)，配置切片(Configured NSSAI)，拒绝切片(如相关技术中已有的、不基于NSSRG的拒绝切片信息)、本申请实施例提出的基于NSSRG的拒绝切片信息、以及切片关联的NSSRG信息。其中，基于NSSRG的拒绝切片信息可以携带于表4所示的扩展拒绝NSSAI中。S302. AMF issues available slices (Allowed NSSAI), configured slices (Configured NSSAI), and rejects slices in the registration response (Registration Accept) (such as rejection slice information that is not based on NSSRG in related technologies). This application implements The example proposed rejects slice information based on NSSRG and slice-associated NSSRG information.

实施例2：Example 2:
图4是根据本申请实施例2的实现流程图，包括以下步骤：Figure 4 is an implementation flow chart according to Embodiment 2 of the present application, including the following steps:
S401、UE当前处于注册态，某个或某些原先可用的NSSRG要更改为不可用，AMF下发配置更新命令(Configuration Update Command)给UE，其中携带要更新的基于NSSRG的拒绝切片信息。基于NSSRG的拒绝切片信息可以采用添加式更新，即AMF下发新的基于NSSRG的拒绝切片列表，可以在上一次的基础上添加新的不可用NSSRG记录。S401. The UE is currently in the registration state, and one or some of the originally available NSSRGs need to be changed to unavailable. The AMF issues a configuration update command (Configuration Update Command) to the UE, which carries the NSSRG-based rejection slice information to be updated. The NSSRG-based rejected slice information can be updated additively, that is, the AMF issues a new NSSRG-based rejected slice list, and new unavailable NSSRG records can be added based on the last one.
S402、UE接收并记录该基于NSSRG的拒绝切片信息，同样地，UE在记录时也可以采用添加式记录的方式，即在原有记录的基础上添加新的基于NSSRG的拒绝切片信息。并且，UE检查当前的每一个Allowed S-NSSAI、及其当前关联的NSSRG组是否已经被拒绝。如果是，则将其从Allowed NSSAI中删除。如果该S-NSSAI已经关联有激活的PDU会话，需要先本地释放该PDU会话。S402. The UE receives and records the NSSRG-based rejection slice information. Similarly, the UE can also adopt an additive recording method when recording, that is, adding new NSSRG-based rejection slice information on the basis of the original record. Furthermore, the UE checks whether each of the current Allowed S-NSSAI and its currently associated NSSRG group has been rejected. If it is, remove it from Allowed NSSAI. If the S-NSSAI is already associated with an activated PDU session, the PDU session needs to be released locally first.
S403、如果UE在当前PLMN下的所有可用切片(Allowed NSSAI)均被删除，UE可以发起更新注册，在更新注册请求中携带的请求切片(Requested NSSAI)，具体采用以下步骤：S403. If all available slices (Allowed NSSAI) of the UE under the current PLMN are deleted, the UE can initiate update registration and include the requested slice (Requested NSSAI) carried in the update registration request. Specifically, the following steps are adopted:
(1)填写当前PLMN下的配置切片(Configured NSSAI)中，那些关联NSSRG仍未被拒绝的切片；(1) Fill in the configured slices (Configured NSSAI) under the current PLMN, those slices whose associated NSSRG has not been rejected;
(2)如果在配置切片中已经没有未被拒绝的切片，则UE可以以缺省配置切片(Default Configured NSSAI)中未被拒绝的切片发起更新注册请求。(2) If there are no unrejected slices in the configuration slice, the UE can initiate an update registration request with the unrejected slice in the default configuration slice (Default Configured NSSAI).
例如，假定UE在NSSRG A下发起更新注册请求，当前PLMN下的配置切片包括S-NSSAI 1、S-NSSAI 2、S-NSSAI 3。按照步骤(1)，UE查找NSSRG A和S-NSSAI 1的信息是否在当前保存的基于NSSRG的拒绝切片信息中，如果NSSRG A和S-NSSAI 1的信息不在基于NSSRG的拒绝切片信息中，则UE可以在NSSRG A下发起更新注册请求，该更新注册请求中携带S-NSSAI 1的标识；如果NSSRG A和S-NSSAI 1的信息在基于NSSRG的拒绝切片信息中，则UE可以进一步查找NSSRG A和S-NSSAI 2的信息；如果NSSRG A和S-NSSAI 1的信息、NSSRG A和S-NSSAI 2的信息、NSSRG A和S-NSSAI 3的信息均不在基于NSSRG的拒绝切片信息中，则UE可以执行步骤(2)，从缺省配置切片(Default Configured NSSAI)中继续查找未被拒绝的切片并发起更新注册请求，查找的方式可以参照前述步骤(1)，在此不再赘述。For example, assuming that the UE initiates an update registration request under NSSRG A, the configuration slices under the current PLMN include S-NSSAI 1, S-NSSAI 2, and S-NSSAI 3. According to step (1), the UE checks whether the information of NSSRG A and S-NSSAI 1 is in the currently saved NSSRG-based rejection slice information. If the information of NSSRG A and S-NSSAI 1 is not in the NSSRG-based rejection slice information, then The UE can initiate an update registration request under NSSRG A, and the update registration request carries the identifier of S-NSSAI 1; if the information of NSSRG A and S-NSSAI 1 is in the NSSRG-based rejection slice information, the UE can further search for NSSRG A and S-NSSAI 2; if the information of NSSRG A and S-NSSAI 1, the information of NSSRG A and S-NSSAI 2, the information of NSSRG A and S-NSSAI 3 are not in the rejected slice information based on NSSRG, the UE Step (2) can be performed to continue to search for unrejected slices from the Default Configured NSSAI and initiate an update registration request. The search method can refer to the aforementioned step (1), which will not be described again here.
以上介绍了原先可用的NSSRG更改为不可用的情况下，终端设备接收及保存基于NSSRG的拒绝切片信息的实现方式。具体可以采用更新式添加的方式，终端设备接收并记录新的基于NSSRG的拒绝切片信息。在原先不可用的NSSRG要更改为可用的情况下，本申请实施例可以将原先保存的基于NSSRG的拒绝切片信息全部删除，接收并记录新的基于NSSRG的拒绝切片信息。The above describes how the terminal device receives and saves the NSSRG-based rejection slicing information when the originally available NSSRG is changed to unavailable. Specifically, an updated addition method can be used, and the terminal device receives and records the new NSSRG-based rejection slicing information. When the originally unavailable NSSRG is to be changed to be available, the embodiment of the present application can delete all the previously saved NSSRG-based rejected slicing information, and receive and record the new NSSRG-based rejected slicing information.

在一些实施方式中，当终端设备去注册的情况下，该终端设备删除基于NSSRG的拒绝切片信息。例如，终端设备在关机、重启、进入飞行模式、拔USIM卡、或者网侧发起去注册等情况下，删除当前保存的基于NSSRG的拒绝切片列表。之后，终端设备可以等待AMF下发新的列表，例如终端设备重新发起注册请求，由AMF在注册响应中下发新的基于NSSRG的拒绝切片信息。In some implementations, when the terminal device deregisters, the terminal device deletes the NSSRG-based rejection slicing information. For example, the terminal device deletes the currently saved NSSRG-based denied slice list when it shuts down, restarts, enters airplane mode, removes the USIM card, or initiates de-registration on the network side. Afterwards, the terminal device can wait for the AMF to deliver a new list. For example, the terminal device re-initiates a registration request, and the AMF delivers new NSSRG-based rejection slice information in the registration response.
