切换方法及终端
相关申请的交叉引用
本申请主张在2019年4月26日在中国提交的中国专利申请号No.201910345898.9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,尤其是指一种切换方法及终端。
背景技术
在相关技术中的切换过程中,当终端向目标小区发起切换时,则不会再收到源小区的配置或者相关指示信息。
为了避免终端在源小区的信道条件恶化后无法接收到源小区的切换命令相关消息,从而引起切换失败,引入条件切换(Conditional Handover)流程。
相关技术中的条件切换过程的主要步骤如下:
步骤1,源小区给一个或多个目标小区发送切换请求信息。
步骤2,目标小区给源小区反馈切换确认信息。
步骤3,源小区给终端发送条件切换的配置信息。
步骤4,终端评估候选小区是否满足条件,满足后选择一个目标小区进行切换。
步骤5,终端在选择的目标小区发起随机接入过程。
步骤6,终端给目标小区发送切换完成信息。
步骤7,源小区给其他目标小区发送取消条件切换命令。
步骤8,其他目标小区给源小区发送条件切换取消确认命令。
综上,在目前的条件切换过程中,当终端判断触发条件满足,则执行切换过程,向目标小区发起接入,如果在此过程中,终端还可能收到源小区的配置或者相关指示信息。此指示信息可能对于相关技术中的切换执行过程有影响,例如,在条件切换过程中,如果接收到源小区的重配、移除或者普通切换命令时,终端该如何处理,相关技术中并没有相关规定。
