Description

一种切换控制方法、网络侧设备及系统 技术领域
本发明涉及通信技术领域,尤其涉及一种切换控制方法、网络侧设备及系统。
背景技术
第4代(4th Generation,4G)移动通信网络,例如长期演进(Long Term Evolution,LTE)网络,目前已经实现了广覆盖。但物联网、车联网等网络需求的出现,用户对于下一代移动通信网络,即第5代(5th Generation,5G)移动通信网络的诉求越来越多。移动通信系统中,切换是必不可少的一项重要功能。因为一个基站的覆盖区域有限,而随着终端的移动,为了保持通信的连续,终端与网络间的无线连接必须由一个网络(小区)转移到另外一个网络(小区),这就是切换。
5G通信系统为了减少切换的时延,引进了一种基于终端的网络切换技术。具体包括如下过程:终端当前附着在第一服务网络,第一服务网络的第一网络侧设备为终端配置用于执行网络切换的测量配置和第一测量事件,终端基于此测量配置针对多个网络进行测量。当针对至少一个网络的测量结果满足第一测量事件时,终端向第一网络侧设备上报该至少一个网络的测量报告,第一网络侧设备根据终端上报的测量报告,为终端确定至少一个网络中的至少一个候选网络,以及为终端配置用于切换至该至少一个候选网络的第二测量事件;当终端检测到针对该至少一个候选网络中的第二网络的信道条件的测量结果满足第二测量事件时,终端向第二网络执行切换操作。
在上述过程中,至少一个候选网络会为终端配置相应的切换准备资源用以执行切换操作,该资源例如包括随机接入资源、终端在候选网络中的临时标识等。由于多个候选网络都为终端配置了切换准备资源,但终端可能在一段时间内或者根本不会切换至某一个候选网络,这种情况会导致候选网络中切换准备 资源的严重浪费。
