本申请主张在2021年10月21日在中国提交的中国专利申请No.202111229129.6的优先权,其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域,具体涉及一种通信方法、装置、核心网设备及通信设备。
背景技术
移动性管理是蜂窝移动通信系统必备的机制,能够辅助第5代(5 th Generation,5G)通信系统实现负载均衡,为用户提供更好的体验以及提高系统整体性能。移动性管理分为两大类:连接态的移动性管理和非连接态的移动性管理。在5G系统内,连接态的移动性管理主要通过网络控制的切换和重定向过程来实现;非连接态的移动性管理主要通过终端控制的小区选择和小区重选过程来实现。
当前,若终端移动至服务小区网络覆盖较差的区域,需要从当前的服务小区切换到新小区,从而尽量保障业务的连续性。然而,相关技术中的切换流程,需要经过测量配置、测量结果上报、切换判决、切换请求、切换许可、重配切换等过程,整体切换时延较长。与之类似的,重定向与重建过程中也存在较长的中断时延。此外,若新小区选择不当,终端在与新小区建立连接之后,可能在短时间内发生无线链路失败(Radio Link Failure,RLF),并向原服务小区或其他新小区发起重建。
