具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。本文中符号“/”表示关联对象是或者的关系，例如A/B表示A或者B。
下面先对本发明实施例所涉及的相关技术，以及一些术语做一个简要的说明，如下所示：
垂直市场对无线通信的强劲需求是有目共睹的，为了满足垂直行业对延迟、移动性、可靠性、位置精度等方面的需求，无线接入网(Radio Access Network，RAN)需要对如何在接入网支持垂直业务进行增强。其中，一种方式为，基于网络切片(slicing)，对不同需求的多个业务提供更低时延、更有目标性、更大的灵活性和更高的可扩展性服务。更具体地说，RAN slicing可以让应用程序提供商参与定制RAN的设计、部署和操作，更好地支持应用程序提供商的业务。因此，Release 17引入接入网对切片(slicing)的增强，具体涉及以下内容：
本课题旨在探讨网络切片对RAN支持的增强，研究项目的详细目标是：研究使UE能够快速访问支持预定切片的小区的机制，包括无线接入网组2[RAN2]：
a、网络控制下基于切片的小区重选；
b、基于切片的RACH(Random Access Channel，随机接入信道)配置或访问限制。
注：研究现有机制是否能满足这种情况或需求。
Rel-15相关技术中，slicing仅涉及核心网侧。具体的，终端设备可以向网络设备上报slicing需求，网络设备根据UE上报的slicing需求，选择合适的接入和移动性管理实体(Access and Mobility Management Function,AMF)，以建立终端设备和网络之间的业务会话。
相关技术中，当UE接入层(Access Stratum，AS)收到UE NAS的切片信息，即单一网络切片选择辅助信息(Single Network Slice Selection Assistance InformationS-NSSAI)后，UE将S-NSSAI信息通过消息5(MSG5)(或空口RRC)消息，通知给基站(gNB)，用于gNB选择合适的接入和移动性管理实体(Access and Mobility Management Function AMF)提供该切片服务。
在R17讨论中，考虑在SIB或dedicated RRC中指示切片相关的信息。但是指示这些切片相关的信息，会有很大的空口信令开销，因此需要考虑如何指示切片相关信息的问题。
