Description

小区确定方法和小区确定装置 技术领域
本公开涉及通信技术领域，具体而言，涉及小区确定方法、小区确定装置、电子设备和计算机可读存储介质。
背景技术
在终端进行小区选择或重选时，可以根据频率优先级确定小区接入。例如基站可以通过广播消息将频率优先级发送给终端，或者通过专有信令为终端配置频率优先级，终端可以确定多个小区的频率，选择具有较高优先级频率的适合的小区接入。
这种小区选择或重选的方式主要是依据基站广播或配置的频率优先级实现，可能没有考虑到终端的实际情况，从而影响小区选择或重选结果的合理性。
发明内容
有鉴于此，本公开的实施例提出了小区确定方法、小区确定装置、电子设备和计算机可读存储介质，以解决相关技术中的技术问题。
根据本公开实施例的第一方面，提出一种小区确定方法，适用于终端，所述方法包括：
通过接入层接收非接入层提供的切片相关信息；
根据所述切片相关信息进行小区选择和/或小区重选。
根据本公开实施例的第二方面，提出一种小区确定装置，适用于终端，所述装置包括：
信息接收模块，被配置为通过接入层接收非接入层提供的切片相关信息；
小区确定模块，被配置为根据所述切片相关信息进行小区选择和/或小区重选。
根据本公开实施例的第三方面，提出一种电子设备，包括：
处理器；
用于存储处理器可执行指令的存储器；
其中，所述处理器被配置为实现上述小区确定方法。
根据本公开实施例的第四方面，提出一种计算机可读存储介质，其上存储有计算机程序，该程序被处理器执行时实现上述小区确定方法中的步骤。
根据本公开的实施例，由于切片相关信息是终端自身将非接入层的切片相关信息提供给接入层，因此在一定程度上可以不受限于网络侧，而是终端根据自身情况在非接入层确定切片相关信息，进而通过接入层接收非接入层提供的切片相关信息，再根据切片相关信息进行小区选择和/或小区重选，可以使得小区选择和/或小区重选的结果更符合终端自身情况。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种小区确定方法的示意流程图。本实施例所示的方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站。
如图1所示，所述小区确定方法可以包括以下步骤：
在步骤S101中，通过接入层接收非接入层提供的切片相关信息；
在步骤S102中，根据所述切片相关信息进行小区选择和/或小区重选。
在一个实施例中，终端可以通过非接入层(Non-Access Stratum，简称NAS)为接入层(Access Stratum，简称AS)提供切片相关信息，其中，所述切片包括网络切片，所述切片相关信息包括但不限于网络切片选择辅助信息、切片的优先级、切片对应频率的优先级等。进而终端可以根据切片相关信息进行小区选择和/或小区重选。
由于切片相关信息是终端自身将非接入层的切片相关信息提供给接入层，因此在一定程度上可以不受限于网络侧，而是终端根据自身情况在非接入层确定切片相关信息，进而通过接入层接收非接入层提供的切片相关信息，再根据切片相关信息进行小区选择和/或小区重选，可以使得小区选择和/或小区重选的结果更符合终端自身情况。
可选地，所述切片相关信息包括请求的网络切片选择辅助信息(Requested NSSAI)和/或允许的网络切片选择辅助信息(Allowed NSSAI)。其中，NSSAI表示网络切片选择辅助信息，全称为Network Slice Selection Assistance Information。
在一个实施例中，以切片相关信息包括网络切片选择辅助信息为例，那么网络切片选择辅助信息可以包括请求的网络切片选择辅助信息，或者可以包括允许的网络切片选择辅助信息，或者既包括请求的网络切片选择辅助信息，又包括允许的网络切 片选择辅助信息。
可选地，所述请求的网络切片选择辅助信息和/或允许的网络切片选择辅助信息是终端发送初始非接入层消息时非接入层提供给接入层的。
在一个实施例中，请求的网络切片选择辅助信息，具体可以是未建立非接入层连接状态下(非接入层处于CM-IDLE状态下，CM是指连接管理Connection Management)终端发送初始非接入层消息时非接入层提供给接入层的请求的网络切片选择辅助信息；允许的网络切片选择辅助信息，具体可以是未建立非接入层连接状态下终端发送初始非接入层消息时非接入层提供给接入层的允许的网络切片选择辅助信息。
可选地，所述请求的网络切片选择辅助信息和/或允许的网络切片选择辅助信息是终端发送非接入层消息更新注册的切片时非接入层提供给接入层的。
在一个实施例中，请求的网络切片选择辅助信息，具体可以是建立了非接入层连接状态下(非接入层处于CM-CONNECTED状态下)，终端发送非接入层消息更新注册的切片时非接入层提供给接入层的请求的网络切片选择辅助信息；允许的网络切片选择辅助信息，具体可以是建立了非接入层连接状态下，终端发送非接入层消息更新注册的切片时非接入层提供给接入层的允许的网络切片选择辅助信息。
在相关技术中，当终端建立非接入层连接后，若终端向网络侧(例如核心网)更新注册的切片，非接入层并不会向接入层提供更新后的请求的网络切片选择辅助信息，在这种情况下，根据本公开图1所示实施例进行小区选择和/或小区重选所依据的切片相关信息，仍是更新前的切片相关信息，难以符合终端最新状态。
本实施例在终端建立非接入层连接后，若终端向网络侧更新注册的切片，非接入层也能够将更新后的请求的网络切片选择辅助信息和/或允许的网络切片选择辅助信息作为切片相关信息提供给接入层，从而确保切片相关信息符合终端最新状态，进而确保根据切片相关信息进行小区选择和/或小区重选的结构符合终端最新状态。
可选地，所述切片相关信息包括公共陆地移动网(Public Land Mobile Network，简称PLMN)选择时，终端非接入层提供给接入层的预配置(preconfigured)的网络切片选择辅助信息。
图2是根据本公开的实施例示出的另一种小区确定方法的示意流程图。如图2所示，所述切片相关信息包括切片优先级关系，所述根据所述切片相关信息进行小区 选择和/或小区重选包括：
在步骤S1021中，根据所述切片优先级关系和从基站接收的第二频率优先级关系，确定目标频率优先级关系；
在步骤S1022中，基于所述目标频率优先级关系进行小区选择和/或小区重选。
图2A是根据本公开的实施例示出的又一种小区确定方法的示意流程图。如图2A所示，所述根据所述切片优先级关系和从基站接收的第二频率优先级关系，确定目标频率优先级关系包括：
在步骤S10211中，根据所述切片优先级关系确定切片关联的频率的第一频率优先级关系；
在步骤S10212中，根据所述第一频率优先级关系和所述第二频率优先级关系确定目标频率优先级关系。
在一个实施例中，切片相关信息可以包括切片优先级关系，例如切片包括切片1和切片2，切片优先级关系可以是切片1的优先级高于切片2的优先级。
在一个实施例中，可以根据切片优先级关系和从基站接收的第二频率优先级关系，确定目标频率优先级关系，例如基站发送给终端多个第二频率优先级关系，并且第二频率优先级关系与切片存在关联，那么可以选择优先级最高的切片对应的第二频率优先级关系作为目标频率优先级关系。
除了上述方式，还可以根据以下方式确定目标频率优先级。
在一个实施例中，可以根据切片优先级关系确定切片关联的频率的第一频率优先级关系，例如切片1关联的频率为f1和f2，切片2关联的频率为f3和f4，那么可以确定频率f1和f2的优先级，高于频率f3和f4的优先级。
另外，基站还会向终端发送第二频率优先级关系，例如基站可以通过广播的方式将第二频率优先级关系发送给终端，也可以通过专用信令的方式将第二频率优先级关系发送给终端。
在相关技术中，在根据频率优先级进行小区选择时，只依据基站向终端发送频率优先级关系进行小区选择或小区重选，而根据本实施例，终端可以先根据切片优先级关系确定切片关联的频率的第一频率优先级关系，而再根据第一频率优先级关系和从基站接收到的第二频率优先级关系确定目标频率优先级关系，最后根据目标频率优 先级关系进行小区选择和/或小区重选。
由于第一频率优先级关系是根据切片优先级确定的，而切片优先级属于切片相关信息，切片相关信息是终端自身将非接入层的切片相关信息提供给接入层，是终端根据自身情况确定的，进而根据目标频率优先级进行小区选择和/或小区重选，有利于确保小区选择和/或小区重选的结果更符合终端自身情况。
图3是根据本公开的实施例示出的又一种小区确定方法的示意流程图。如图3所示，所述方法还包括：
在步骤S103中，确定每个切片分别关联的频率的第三频率优先级关系；
其中，所述根据所述切片优先级关系确定第一频率优先级关系包括：
在步骤S102111中，对于不同切片关联的频率，确定高优先级的切片关联的频率的优先级，高于低优先级的切片关联的频率的优先级；
在步骤S102112中，根据所述第三频率优先级关系确定同一切片关联的频率的优先级。
在一个实施例中，每个切片可以分别关联频率，例如切片1关联的频率为f1和f3，切片2关联的频率为f2和f3，针对切片所关联的频率，网络侧可以设置频率优先级关系，以下称作第三频率优先级关系，例如切片1关联的频率f1和f3的第三频率优先级关系为f1的优先级高于f3的优先级，切片2关联的频率f2和f3的第三频率优先级关系为f2的优先级高于f3的优先级。
在此基础上，对于不同切片关联的频率，可以确定高优先级的切片关联的频率的优先级，高于低优先级的切片关联的频率的优先级，例如对于上述切片1和切片2而言，f1的优先级高于f2和f3的优先级，且f3的优先级高于f2和f3的优先级。
由于频率的优先级不会高于该频率自身的优先级，所以对于上述f3的优先级高于f3的优先级的情况可以自动删除，那么就是f1的优先级高于f2和f3的优先级，且f3的优先级高于f2的优先级。
而对于f1和f3之间的优先级，两者为同一切片关联的频率，也即切片1关联的频率，那么可以根据切片1对应的第三频率优先级关系确定f1和f3之间的优先级，也即f1的优先级高于f3的优先级。
由于f1的优先级高于f2和f3的优先级，且f3的优先级高于f2的优先级，且 f1的优先级高于f3的优先级。那么最终可以确定f1、f2和f3三个频率的优先级关系为f1>f3>f2。
可选地，所述切片优先级关系根据所述终端的策略确定，和/或根据第一非接入层消息指示的所述终端中应用程序的优先级确定。
在一个实施例中，切片优先级关系可以根据终端的策略确定，也可以根据第一非接入层消息指示的终端中应用程序的优先级确定。
其中，终端的策略可以由终端自身设置，例如由终端的制造商设置，也可以由终端的使用者设置，而终端的策略属于非接入层的信息。
第一非接入层消息例如可以是URSP(UE Route Selection Policy，UE路由选择策略)Rule(s)，URSP Rule(s)能够对应终端中的应用程序，网络侧可以确定URSP Rule(s)的优先级，进而可以根据URSP Rule(s)的优先级确定对应应用程序的优先级。
图4是根据本公开的实施例示出的又一种小区确定方法的示意流程图。如图4所示，所述方法还包括：
在步骤S104中，响应于根据终端的策略确定的切片优先级关系和根据第一非接入层消息指示的所述终端中应用程序的优先级确定的切片优先级关系冲突，根据第二非接入层消息确定选择根据终端的策略确定的切片优先级关系或选择根据第一非接入层消息指示的所述终端中应用程序的优先级确定的切片优先级关系。
在一个实施例中，当根据终端的策略确定的切片优先级关系和根据第一非接入层消息指示的所述终端中应用程序的优先级确定的切片优先级关系冲突时，例如根据终端的策略确定的切片优先级关系为切片1的优先级高于切片2的优先级，而根据第一非接入层消息指示的所述终端中应用程序的优先级确定的切片优先级关为切片2的优先级高于切片1的优先级。
那么终端可以接收第二非接入层消息，或者第二非接入层消息与第一非接入层消息为同一条消息，第二非接入层消息可以指示在上述切片优先级关系存在冲突的情况下，选择哪个优先级关系，因此可以根据第二非接入层消息确定选择根据终端的策略确定的切片优先级关系或选择根据第一非接入层消息指示的所述终端中应用程序的优先级确定的切片优先级关系。
图5是根据本公开的实施例示出的又一种小区确定方法的示意流程图。如图5所示，所述根据所述第一频率优先级关系和所述第二频率优先级关系确定目标频率优 先级关系包括：
在步骤S102121中，响应于所述第二频率优先级关系携带在所述基站的广播消息中，确定所述第一频率优先级关系中频率的优先级高于所述第二频率优先级关系中频率的优先级。
在一个实施例中，在第二频率优先级关系是基站通过广播消息发送给终端时，由于广播消息并非针对性地发送，也即并不一定是为终端针对性指示的，在这种情况下，一般而言根据切片优先级确定的第一频率优先级关系相对第二频率优先级关系，更符合终端当前的情况，因此可以确定所述第一频率优先级关系中频率的优先级高于所述第二频率优先级关系中频率的优先级。
图6是根据本公开的实施例示出的又一种小区确定方法的示意流程图。如图6所示，所述根据所述第一频率优先级关系和所述第二频率优先级关系确定目标频率优先级关系包括：
在步骤S102122中，响应于所述第二频率优先级关系携带在所述基站发送至所述终端的第一专用信令中，确定所述第一频率优先级关系中频率的优先级高于所述第二频率优先级关系中频率的优先级。
在一个实施例中，在第二频率优先级关系是基站通过第一专用信令发送给终端时，由于第一专用信令是基站发送给终端的，但是基站可能并不知道终端当前的情况，在这种情况下，一般而言根据切片优先级确定的第一频率优先级关系相对第二频率优先级关系，更符合终端当前的情况，因此可以确定所述第一频率优先级关系中频率的优先级高于所述第二频率优先级关系中频率的优先级。
可选地，所述确定所述第一频率优先级关系中频率的优先级高于所述第二频率优先级关系中频率的优先级包括：
在第一频率优先级关系对应频率中确定属于所述第二频率优先级关系对应频率的交集频率；
根据所述第一频率优先级关系确定所述交集频率中频率的优先级，以及确定所述交集频率的优先级高于所述第二频率优先级关系中其他频率的优先级。
在一个实施例中，由于基站发送给终端的第二频率优先级关系对应频率，一般是该基站对应小区的邻小区的频率，也即是接收到第二频率优先级关系的终端需要确定的频率，而终端根据切片信息确定的第一频率优先级关系对应的频率，可能并非都 是需要确定的频率。
终端需要确定的频率，是指针对这些频率，终端确定频率之间的优先级之后，按照频率优先级顺序，优先对高优先级频率下的小区进行测量，选择高频率优先级的最高信号质量的合适小区。
例如第一频率优先级关系对应频率为f1、f2、f3、f4和f5，第一频率优先级关系为f4>f2>f1>f3>f5；第二频率优先级关系对应频率为f1、f2和f3，第一频率优先级关系为f1>f3>f2。一般情况下，f1、f2和f3为终端需要确定的频率，f4和f5则并不是终端需要确定的频率。也即终端在进行小区选择、小区重选等需要确定频率(例如小区的频率)的操作时，需要考虑第二频率优先级关系对应的每个频率，但是并不一定要考虑第一频率优先级关系对应的每个频率。
终端可以在第一频率优先级关系对应频率中先确定属于第二频率优先级关系对应频率的交集频率，例如上述f1、f2和f3即交集频率。进而可以确定交集频率的优先级高于第二频率优先级关系中其他频率的优先级，其他频率是指交集频率以外的频率，由于上述情况下并没有其他频率，所以只需确定f1、f2和f3的优先级即可，那么确定的优先级就是f1>f3>f2，无需考虑f4和f5的优先级，有利于减少终端所需确定优先级的频率。
例如第一频率优先级关系对应频率为f1、f2、f3，第一频率优先级关系为f1>f3>f2；第二频率优先级关系对应频率为f1、f2、f3、f4和f5，第二频率优先级关系为f4>f2>f1>f3>f5。一般情况下，f1、f2、f3、f4和f5为终端需要确定的频率。
那么f1、f2和f3为交集频率，其他频率为f4和f5，也即f1、f2和f3的优先级高于f4和f5的优先级，其中，f1、f2和f3的优先级可以根据第一频率优先级关系确定，也即f1>f3>f2，其他频率由于只属于第二频率优先级关系，所以可以根据第二频率优先级关系确定其他频率的优先级，也即f4>f5，那么最终确定的优先级就是f1>f3>f2>f4>f5，从而可以确保确定需要确定的频率的优先级。

在一个实施例中，在第二频率优先级关系是基站通过第一专用信令发送给终端时，由于第一专用信令是基站发送给终端的，更符合基站的需要，因此可以确定所述第二频率优先级关系中频率的优先级高于所述第一频率优先级关系中频率的优先级。
