Description

寻呼方法、RAN-UP实体、RAN-CP实体及UE 技术领域
本申请涉及但不限于无线通信技术，尤指一种寻呼方法、RAN-UP(Residential Access Network User Plane，居民接入网用户面)实体、RAN-CP(Residential Access Network Control Plane，居民接入网控制面)实体及用户设备(UE，User Equipment)。
背景技术
蜂窝移动通信技术已经进入4G时代，但为了满足未来更高、更快、更新的通信需求，业界已经着手展开对5G技术的研究。5G将在更大的吞吐量、更多的用户连接、更低时延、更高可靠性、更低功耗方面进行进一步的技术研究。目前，业界提出了5G技术目标：到2020年左右，实现每区域1000倍的移动数据流量增长，每UE 10到100倍的吞吐量增长，连接设备数10到100倍的增长，低功率设备10倍的电池寿命延长，以及端到端5倍延迟的下降。
所以相对4G，5G研究提出了更高的性能要求，其中之一就是对控制面状态转换(从不发数据到可以传输数据)提出了10ms的指标要求，并在此基础上UE可以尽可能省电。因此，需要一种新的UE状态—休眠态。在休眠态下，UE和网络侧没有专用连接态资源，网络侧和核心网之间保持着UE级承载连接。由于5G终端的多样性，这种休眠态可以适用于手机、物联网器件等各类终端和业务，这些业务的优先等级以及数据包特性都会对休眠态提出新的需求。同时，随着居民接入网(RAN，Residential Access Network)软件定义网络(SDN，Software Defined Network)化的趋势，RAN的控制面和RAN的用户面也趋向于一种分离架构，这样RAN控制面锚点可以和RAN用户面锚点分离，从而实现一种SDN化的灵活部署架构。
