Description

数据无线承载的恢复方法、终端、基站及核心网设备
相关申请的交叉引用
本申请主张在2017年9月29日在中国提交的中国专利申请号No.201710906806.0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，特别的指一种数据无线承载的恢复方法、终端、基站及核心网设备。
背景技术
5G移动通信系统中引入了业务区域限制(Service area restrictions)。统一数据管理(Unified Data Management，UDM)将存储的终端业务区域限制信息纳入该终端的订阅数据。对不同的终端UE，基于其订阅信息来确定相应的非允许区域和允许区域。在非允许区域，仅支持如紧急业务和MPS之类的优先业务。网络可对处于非允许区域的终端执行寻呼，以通用的终端配置更新过程来更新该终端的业务区域限制。业务区域限制范围可包含一个或多个完整的跟踪区(tracking area，TA)。另外，在非允许区域内可进行TA更新。
在5G移动通信系统中，可基于不同终端UE的订阅信息确定其非允许区域(non-allowed area)和允许区域(allowed area)。当处于RRC_INACTIVE(非活跃)状态的终端从其允许区域移动到非允许区域时，由于非允许区域仅允许终端收发如紧急业务和MPS(Multimedia Priority Service，多媒体优先业务)之类的优先业务，而处于RRC_INACTIVE状态的终端在优先业务到达触发的RRC连接恢复过程中将恢复所有挂起的数据无线承载，从而造成终端恢复的部分数据无线承载(DRB)无法使用，浪费了网络资源。
