Definitions

  • the present disclosure relates to the field of communication technologies, and in particular, to a slice registration method, device, terminal, and network node.
  • TA area A only supports slice 1 registration
  • TA area B supports slice 1 and slice 9 registration
  • TA area C supports slice 1 and slice 10 registration
  • the Configured NSSAI set of terminal 1 is ⁇ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ⁇ ;
  • the terminal 1 initiates the tracking area registration process in the TA area A and the registration area allocated to the terminal by the network side is the TA area ⁇ A, B, C ⁇ . If the terminal then initiates the slice registration process in the TA area A and the requested slice set is ⁇ 1, 2, 3, 4, 5, 6, 7, 8 ⁇ , after the registration area A initiates the slice registration process, the terminal can only successfully register slice 1, and the registration of slice 2 to slice 8 will be rejected.
  • the terminal moves to the border area of TA area A and TA area B, and slice 9 can also be registered, but the terminal in idle (idle) and/or inactive (inactive) state does not know that TA area B supports slice 9 registration, because the terminal does not move out
  • the registered tracking area ⁇ A, B, C ⁇ the terminal will not blindly initiate slice 9 registration before the slice 9 service is initiated.
  • the problem is that once the user tries to initiate the slice 9 service, it can only temporarily perform slice 9 registration. If the registration of slice 9 is initiated in tracking area B, the registration of slice 9 is successful; if the terminal initiates registration of slice 9 in tracking area C, the registration of slice 9 fails.
  • the above scenario has the following problems:
  • Disadvantage 1 In the random slice registration process in the related art, the terminal cannot know the changes of the registration authority of other TA areas or cell slices in time. As shown in Figure 1, the terminal cannot perceive that TA area B or C supports different support than TA area A. Slice collection, so that the terminal cannot perform local adaptive slice registration;
  • Disadvantage 2 In the random slice registration process in the related art, the terminal cannot optimize the slice set to be registered according to the new TA area or the change of the cell slice registration authority. As shown in Figure 1, the terminal cannot perceive the relative TA area B or C relative to the TA. Area A supports different slice sets, which causes the terminal to register slices other than slice 1 and slice 9 in TA area B. For example, the terminal registers slice 10 in TA area B, but the final result is to reject slice 10 registration;
  • Disadvantage 3 In the random slice registration process in the related art, the terminal does not always try to register all the Configured NSSAI sets, because a maximum of 8 slice registrations are attempted at a time, while the Configured NSSAI may have dozens of types, and the slice registration process is frequent It is also a network burden, so the limited slice registration process can only be carried out by implementing algorithms such as user preferences, as shown in Figure 1, if slice 9 has not tried to register in TA area A, then when the terminal moves to TA area B, the terminal does not method to determine whether slice 9 should be registered, because the terminal tracking area is still ⁇ A, B, C ⁇ , if slice 9 is registered only when the service of slice 9 is initiated, the service delay brought by the registration process will reduce the user experience; another On the other hand, if the terminal first selects the TA area B cell to register the slice 10 at the junction of the TA area B and the TA area C, the registration process of the slice 10 fails, and the terminal needs to reselect the cell in the TA

本申请主张在2020年7月15日在中国提交的中国专利申请号No.202010683117.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种切片注册方法、装置、终端及网络节点。
背景技术
相关技术的切片注册过程具有随机性的特点，如图1所示：
TA区域A仅支持切片1注册，TA区域B支持切片1和切片9注册，TA区域C支持切片1和切片10注册；
假设终端1的Configured NSSAI集合为{1，2，3，4，5，6，7，8，9，10}；
初始时终端1在TA区域A发起跟踪区域注册过程且网络侧分配给终端的注册区域为TA区域{A，B，C}，如果终端接着在TA区域A发起切片注册过程且请求的切片集合为{1，2，3，4，5，6，7，8}，则在注册区域A发起切片注册过程后，终端只能成功注册切片1，切片2～切片8的注册会被拒绝，随着终端移动到TA区域A与TA区域B交界区域，切片9也可以注册，但是idle(空闲)和/或inactive(非激活)态终端并不知道TA区域B支持切片9注册，因为终端并未移出其注册的跟踪区域{A，B，C}，终端在切片9业务发起前，不会盲目发起切片9注册，问题在于一旦用户准备尝试发起切片9业务则只能临时进行切片9注册，如果正好在跟踪区域B发起切片9注册，则切片9注册成功；如果终端在跟踪区域C发起切片9注册，则切片9注册失败，上述场景存在如下若干问题：
缺点1：相关技术中的随机切片注册过程，终端并不能及时知道其他TA区域或者小区切片注册权限的变化情况，如图1所示，终端无法感知TA区 域B或者C相对于TA区域A支持不同切片集合，导致终端无法进行本地适应性切片注册；
缺点2：相关技术中的随机切片注册过程，终端无法根据新的TA区域或者小区切片注册权限的变化优化请求注册的切片集合，如图1所示，终端无法感知TA区域B或者C相对于TA区域A支持不同切片集合，导致终端在TA区域B注册除切片1和切片9之外的其他切片，例如终端在TA区域B注册切片10，最终的结果还是拒绝切片10注册；
缺点3：相关技术中的随机切片注册过程，终端并不总是将Configured NSSAI集合都尝试注册一遍，因为一次最多尝试8种切片注册，而Configured NSSAI可能多达几十种，频繁的切片注册过程也是一种网络负担，那么有限的切片注册过程只能采取用户喜好等实现算法进行，如图1，如果切片9在TA区域A没有尝试注册过，那么在终端移动到TA区域B时，终端没法判断应不应该注册切片9，因为终端跟踪区域还是{A，B，C}，如果在切片9业务发起时才注册切片9，注册过程带来的业务时延就降低了用户体验；另一方面，如果终端在TA区域B与TA区域C交界处首先选择TA区域B小区注册切片10，则切片10注册过程失败，终端进而需要重选到TA区域C内的小区再次注册切片10才能成功，在TA区域B注册切片10失败到重选到TA区域C内的小区再次注册切片10耗费的时延更大，用户的体验更差。
综上，由于终端不能进行本地适应性切片注册带来的业务时延会大大降低用户体验度。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
首先对相关内容介绍如下：
切片(Slice)是新无线接入技术(New RAT，NR)系统新引入的概念，主要目的在于为不同的业务划分不同的资源管理模式，从而在增加业务隔离度的同时也能根据业务类型优化资源管理方式；具体的，关于NR切片：
网络切片是一种面向业务的资源封装概念，一种网络切片通过网片选择辅助标识(Network Slice Selection Assistant Identity，NSSAI)唯一标示，同时也对应着一种类型的资源配置。不同的核心网可以根据需求支持不同类型的网络切片，与长期演进(Long Term Evolution，LTE)系统注册不同的是，终端在网络中使用某种切片之前需要进行该切片的注册，终端只有在该切片注册成功后才能发起该切片对应的会话建立过程。切片注册过程中，终端请求注册的NSSAI信息(Request NSSAI)从终端存储的Configured NSSAI或者Default NSSAI中选取且约束终端一次最多只能请求注册8个S-NSSAI(Single NSSAI)信息；核心网根据终端签约信息、终端的Request NSSAI、本地支持的切片信息以及本地策略生成终端的Allowed NSSAI以及Rejected(拒绝接受的)NSSAI。
终端也会预配置或者从核心网获取Configured NSSAI，该配置是PLMN唯一的，如果终端配置的某一PLMN没有配置Configured NSSAI，则使用Default NSSAI信息。
NR系统核心网定义，一个切片对应一个S-NSSAI(Single NSSAI，单网片选择辅助标识)标识，一个S-NSSAI标识由切片类型标识切片/服务类型(Slice/Service Type，SST)和切片区分标识切片差异区分器(Slice  Differentiator，SD)组成，其中切片类型标识SST占用8个比特且是必须出现的，切片区分标识SD占用24个比特且是可选出现的。
另外，切片在终端侧的应用采取先注册再发起业务的原则进行，终端请求注册的NSSAI信息(Request NSSAI)从终端存储的Configured NSSAI或者Default NSSAI中选取且约束终端一次最多只能请求注册8个S-NSSAI信息，这样的设计带来的后果是如果终端实际准备发起的切片业务没有注册，终端只能为准备发起的业务对应的切片发起切片再次注册过程，即使注册成功，切片再次注册过程也带来了额外的时延；另一方面，如果终端发起的切片再次注册过程失败，也带来了用户侧无用等待时延，总的来讲，相关技术的切片注册过程给用户带来了不利的用户体验。
基于以上，本公开针对相关的技术中切片注册方案不合理、切片注册时延大的问题，提供一种切片注册方法，应用于终端，如图2所示，包括：

举例二：第一网络节点通过专用信令向终端发送频点集合以及该频点集合中各个频点所支持切片类型的标识信息
如图5所示，包括：
步骤51：第一网络节点通过专用信令向终端发送频点集合以及该频点集合中各个频点所支持切片类型的标识信息；
步骤51中所述的专用信令承载的信息包含如下信息中的至少一项：

步骤52：终端回复第一网络节点(即终端向第一网络节点回复)配置成 功信息，该过程可以不出现。
举例三：应用本方案后终端非接入层进行切片注册的行为举例
关于跟踪区域TA及切片支持情况如图6所示：
TA区域A仅支持切片1注册，TA区域B支持切片1和切片9注册，TA区域C支持切片1和切片10注册；
假设终端1的Configured NSSAI集合为{1，2，3，4，5，6，7，8，9，10}；
初始时终端1在TA区域A发起跟踪区域注册过程且网络侧分配给终端的注册区域为TA区域{A，B，C}，如果终端接着在TA区域A发起切片注册过程且请求的切片集合为{1，2，3，4，5，6，7，8}，则在注册区域A发起切片注册过程后，终端只能成功注册切片1，切片2～切片8的注册会被拒绝，随着终端移动，如果终端移动到TA区域B小区且终端的非接入层从终端的非接入层已经获取了网络侧根据预设信息生成的频点集合以及该频点集合中各个频点所支持切片类型的标识信息，则终端在TA区域B小区只会发起切片1和/或切片9的注册过程；如果终端移动到TA区域C小区且终端的非接入层从终端的非接入层已经获取了网络侧根据预设信息生成的频点集合以及该频点集合中各个频点所支持切片类型的标识信息，则终端在TA区域C小区只会发起切片1和/或切片10的注册过程。
根据上述切片注册过程，终端会在用户发起切片9或者切片10业务之前完成相应切片注册，减少了用户发起切片9或者切片10业务时延。
由上可知，本公开实施例提供的方案中终端可以根据频点所支持切片类型的标识信息适应性进行切片注册过程，既减少了不必要的切片注册过程，也因为提前根据频点所支持切片类型的标识信息适应性进行切片注册过程，同时也降低了用户切片业务时延，提高了用户体验度。
