在阅读并理解了附图和详细描述后，可以明白其他方面。
附图说明
下面将对实施例或相关技术描述中所需要使用的附图作简单地介绍，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。
在相关技术中，多连接架构的一种形式如图1所示，在宏小区1中分布了两个微小区群和一个单独小区。在图1的多连接架构中，终端可以保持与宏小区1的数据连接，与此同时，终端还可以与至少一个微小区(如微小区群1或微小区群2中的微小区)中的至少一个保持数据连接。类似于这样的架构被称之为多连接架构。
在相关技术中，一个典型的网络切片包括一组虚拟化的接入网功能和核心网功能。网络切片由运营商根据需求和策略进行构建，一个网络切片包括的功能也由运营商根据需求和策略决定。比如，某些网络切片除了包括控制面功能外还可以包括专用的转发面；而某些网络切片可能只包括一些基本的控制面功能。图2为相关技术中通用网络切片示意图，其中，通用网络为通用的业务提供服务，而在将网络切片后，会产生定制化的网络切片，提供三种不同类型的服务。例如：类型A为超高速业务，如视频业务，虚拟现实等；类型B为突发小业务数据业务，如QQ、微信等；类型C为低时延超可靠业务，如车联网，智能电网等。每一种类型根据一些差异，生成不同的网络切片实例(如业务需求和商业模式等不同，例如：类型A进行视频业务，根据视频类型对业务速率的要求， 分为支持普通视频的切片A1，支持高清视频的切片A2。一个网络切片构成一个虚拟网络，为终端提供一种特定的移动网络接入服务。
将上述两个相关技术进行结合的一种可能方式为多连接架构下网络切片的部署，其中，多连接架构下网络切片部署的一种形式如图3所示。在基站1(称为主基站)的宏服务小区覆盖范围内，配置了基站2和基站3(称为辅基站)各自的微服务小区。基站1支持网络切片1，基站2支持网络切片2，基站3支持网络切片3。但是，只有基站1和核心网网元有控制面连接，处于双连接或多连接工作模式下的基站2和基站3作为辅基站和核心网网元没有控制面连接。所以，核心网网元并不知道基站2和基站3的切片能力。
因此，在基站1和核心网网元交互信息时，不仅需要携带基站1所支持的切片能力信息，还需要携带基站2和基站3的切片能力信息。这样，核心网网元就可以知道基站2和基站3的切片能力。核心网网元能为被服务终端配置这些切片上的资源，提供切片对应的无线承载业务，终端可以进入双连接或多连接工作模式。
基于此，本申请实施例提出了一种网络切片配置方法，可以使得辅基站的切片能力信息为核心网网元所知，以使核心网网元为终端配置这些切片上的资源，提供切片对应的无线承载业务，终端可以进入双连接或多连接工作模式。
本申请的一个实施例如图4所示，图4中示出了一种网络切片配置方法，该方法应用于主基站，包括步骤S101和步骤S102。
在步骤S101中，主基站根据所述主基站的网络切片信息和辅基站的网络切片信息，生成联合网络切片信息。
在步骤S102中，所述主基站发送所述联合网络切片信息给核心网网元。
本实施例中，主基站根据主基站的切片网络信息和辅基站的网络切片信息，生成联合网络切片信息，并将联合网络切片信息发送给核心网网元。通过上述方案，主基站与核心网网元交互时，不仅携带主基站的网络切片信息，同时，还携带辅基站的网络切片信息，因此，核心网网元可以获取与核心网网元无控制面连接的辅基站的网络切片信息。
上述步骤的详细内容如下所示：
在步骤S101之前，主基站获取辅基站的网络切片信息。
其中，所述辅基站的网络切片信息由辅基站发送给主基站。所述辅基站的网络切片信息包括：辅基站的注册区域和辅基站的切片能力信息(也即辅基站所支持的注册区域和切片能力信息)。辅基站的注册区域可以是辅基站的跟踪区(Trace area，TA)，辅基站的切片能力信息用于核心网网元为终端配置该切片的资源，提供该切片对应的无线承载业务。其中，辅基站切片能力信息为辅基站所能提供的网络切片服务对应的切片能力信息。
在步骤S101中，所述主基站根据所述主基站的网络切片信息和辅基站的网络切片信息，生成联合网络切片信息。
所述主基站的网络切片信息包括：主基站的注册区域和主基站的切片能力信息(也即主基站所支持的注册区域和切片能力信息)。主基站的注册区域可以是主基站的TA，主基站的切片能力信息用于核心网网元为终端配置该切片的资源，提供该切片对应的无线承载业务。其中，主基站切片能力信息为主基站所能提供的网络切片服务对应的切片能力信息。
针对所述联合网络切片信息可以有以下两种不同的方式：
方式一：所述主基站在所述主基站的网络切片信息中增加所述辅基站的切片能力信息。该种方式下，所述联合网络切片信息包括：主基站的注册区域、主基站的切片能力信息、以及辅基站的切片能力信息。
方式二：所述主基站在所述主基站的网络切片信息中增加所述辅基站的注册区域和切片能力信息。该种方式下，所述联合网络切片信息包括：主基站的注册区域、主基站的切片能力信息、辅基站的注册区域、以及辅基站的切片能力信息。
在一个实施例中，在方式二的基础上，所述联合网络切片信息包括指示信息。所述指示信息用于指示终端是否满足多连接条件，终端只有在多连接架构下，才能同时与主基站和辅基站连接，终端触发的针对辅基站的切片请求才会被接收。因此，当指示信息中未对终端是否满足多连接条件进行指示，那么终端就不会发起针对辅基站的切片请求，这样可以避免不必要的信令尝试，提升用户的使用体验。
针对指示信息，可以包括以下至少之一：所述辅基站的注册区域与主基站的注册区域的多连接关系；所述辅基站的注册区域与主基站的切片能力信息的多连接关系；所述辅基站的切片能力信息与主基站的注册区域的多连接关系； 所述辅基站的切片能力信息与主基站的切片能力信息的多连接关系。其中，所述多连接关系用于指示终端满足多连接条件。
若满足多连接关系，则一个终端可以同时连接到多个基站上进行数据传输。例如，若终端同时处于主基站和辅基站的覆盖范围之内，并且终端、主基站、辅基站处于多连接架构下，则该终端满足多连接条件，指示消息可以为所述辅基站的注册区域与主基站的注册区域的多连接关系。若终端处于主基站的覆盖范围之内，而未处于辅基站的覆盖范围之内，则该终端不满足多连接条件，联合网络切片信息中就不会携带指示信息。
在步骤S102中，所述主基站发送所述联合网络切片信息给核心网网元。
其中，所述联合网络切片信息可以通过NG接口中的NG-eNB Configuration Update、NG-gNB Confguration Update、NG setup request或者新定义的消息发送给核心网网元。其中，NG接口为5G核心网网元和接入网网元之间的接口，NG-eNB Configuration Update为5G核心网网元和4G基站配置更新消息，NG-gNB Configuration Update为5G核心网网元和5G基站配置更新消息，NG setup request为5G接口建立请求消息，新定义的消息为例如网络切片更新配置消息。
在一个实施例中，在步骤S101-S102的基础上，所述主基站广播所述主基站的网络切片信息和辅基站的网络切片信息。终端在接收到上述广播的信息之后，会根据这些信息发起注册请求。根据主基站和辅基站的网络切片信息(网络切片信息包括注册区域和切片能力信息)，终端选择可能的注册区域和切片能力进行注册请求。这样，可以减少信令负荷，避免对于不可能的注册区域和切片能力进行注册请求。同时，根据所述指示信息，终端可以获知自身是否满足多连接条件，当满足多连接条件时，才发起对辅基站的注册请求。因为，如果终端不满足多连接条件(例如，终端未处于辅基站覆盖的范围内)，终端发起的针对辅助基站切片的请求会被拒绝。这样，也可以减少信令负荷，避免造成不必要的信令尝试。
在一个实施例中，在步骤S101和步骤S102的基础上，所述主基站接收终端发送的注册请求。其中，注册请求用于告知核心网网元所述终端待获取的网络切片服务。
所述主基站发送所述注册请求给所述核心网网元。
所述主基站接收所述核心网网元发送的注册网络切片信息，其中，注册网 络切片信息由所述核心网网元根据联合网络切片信息和注册请求配置。同时，所述注册网络切片信息包括允许终端注册的注册区域，以及允许终端获取的网络切片服务对应的切片能力信息。所述注册网络切片信息用于告知终端，该终端可以获取的网络切片服务(终端待获取的网络切片服务，由于该终端不在网络切片对应的注册区域内等一些原因，终端无法获取)。例如，由上述方式二生成网络切片信息，该网络切片信息包括：主基站的注册区域、主基站的切片能力信息、辅基站的注册区域、以及主基站的切片能力信息。如果终端待获取的网络切片服务为所有辅基站的网络切片服务，那么核心网网元为终端配置辅基站的注册区域、以及辅基站的切片能力信息。
所述主基站发送所述注册网络切片信息给所述终端。所述终端接收到所述注册网络切片信息后，根据该注册网络切片信息，获取网络切片服务。
上述实施例中，主基站接收辅基站的网络切片信息，根据主基站的切片网络信息和辅基站的网络切片信息，生成联合网络切片信息，并将联合网络切片信息发送给核心网网元。主基站在接收终端发送的注册请求后转发给核心网网元，核心网网元根据注册请求配置注册网络切片信息，主基站在接收核心网网元发送的注册网络切片信息后转发给终端。最终，终端根据注册网络切片信息，获取网络切片服务。通过上述方案，核心网网元可以根据与核心网网元无控制面连接的辅基站的网络切片信息为终端配置注册网络切片信息，以使终端可以获取与辅基站的网络切片信息对应的网络切片服务。

其中，核心网网元向主基站发起数据连接请求。所述数据连接请求可以是分组会话资源建立请求(PDU SESSION RESOURCE SETUP REQUEST)，在所述数据连接请求中携带辅基站2的切片能力信息1、TA1与TA3的多连接关系、以及TA3。也即，本次数据连接请求，核心网网元会使得终端获取辅基站2的切片能力信息1所对应的网络切片服务。
在步骤2中，主基站配置多连接。
主基站接收到数据连接请求，获得辅基站2的切片能力信息1、TA1与TA3的多连接关系、以及TA3。但是，实际上主基站只能为终端提供主基站的切片能力信息1和主基站的切片能力信息1所对应的网络切片服务，因此，主基站进一步查询，可以为终端提供辅基站2的切片能力信息1对应的网络切片服务的为辅基站2。
由于数据连接请求中包括TA1与TA3的多连接关系，因此可以判断终端满足多连接条件，则主基站为终端配置多连接。
主基站可以通过相关技术为终端配置双连接，参考3GPP协议36.300中对双 连接的描述。其中，该数据连接的用户面最终配置在辅基站2上。在双连接下，终端的控制面连接到主基站，并经过主基站连接到核心网网元的控制面实体；终端归属于辅基站2的切片能力信息对应的切片服务的数据连接连接到辅基站2并通过辅基站2连接到核心网网元的用户面实体。
在一个实施例中，如果终端不满足配置多连接的条件，且终端的数据连接只能在指定切片中执行，则主基站拒绝数据连接的请求。例如，终端移动到辅基站2的覆盖范围之外的时候，核心网网元发起对该终端的数据连接，且连接归属于辅基站2的切片能力信息对应的切片服务，则辅基站2在这种情况下拒绝该数据请求的建立。
