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。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信(5th-Generation，5G)系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
本申请实施例结合网络设备和终端设备描述了各个实施例，其中：终端设备也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。终端设备可以是WLAN中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统，例如，NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及NR网络中的网络设备(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图1示例性地示出了一种通信系统100。该通信系统包括一个网络设备110和两个终端设备120。可选地，该通信系统100可以包括多个网络设备110，并且每个网络设备110的覆盖范围内可以包括其它数量的终端设备120，本申请实施例对此不做限定。
可选地，该通信系统100还可以包括移动性管理实体(Mobility Management Entity，MME)、接入与移动性管理功能(Access and Mobility Management Function，AMF)等其他网络实体，本申请实施例对此不作限定。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。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。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
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的服务。更具体地说，RAN切片(slicing)可以让应用程序提供商参与定制RAN的设计、部署和操作，以更好地支持应用程序提供商的业务。
因此，引入了接入网对切片(slicing)的增强，主要涉及网络切片对RAN支持的提升。例如：
1.使UE能够快速访问支持预定切片的小区的机制，包括[RAN2]
a、网络控制下基于切片的小区重选。
b、基于切片的RACH(随机接入)配置或接入限制。
并且，包括是否有能满足这个场景或需求的机制。
2.支持服务连续性的必要性和机制，包括[RAN3]
a、对于RAT(Radio Access Technology，无线接入技术)内切换服务中断，例如，目标gNB不支持UE的持续切片、研究切片重新映射、回退和数据转发过程。需要与SA2协调。
在相关技术中，关于切片(Slicing)标识，RAN侧针对每一个切片定义了单一网络切片选择辅助信息(Single Network Slice Selection Assistance Information，S-NSSAI)。UE侧维护了NSSAI，NSSAI是一个S-NSSAI列表，UE最多支持8个S-NSSAI。
S-NSSAI由SST(Slice/Service Type，切片服务类型)和SD(Slice Differentiator，切片区分符)组成，SST代表业务类型，SD代表相同(same)SST下服务的不同UE组。
本申请实施例中，考虑了网络切片部署限制的问题。切片的部署可能是与位置(location)等因素相关的，在特定部署下有特定的切片。因此，考虑相关机制，可以使得UE能够合理选择自己需要的切片，快速接入，避免UE接入和业务服务时延。
