Description

一种小区切换及其控制方法及装置
相关申请的交叉引用
本申请要求在2021年05月11日提交中国专利局、申请号为202110508632.9、申请名称为“一种小区切换及其控制方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种小区切换及其控制方法及装置。
背景技术
现有技术中关于条件切换(Conditional Handover,CHO)，或条件PSCell(Primary Secondary cell，主辅小区)添加或改变(Conditional PSCell Additional/Change，CPAC)切换的主要思想：
为了提高移动的鲁棒性和可靠性，版本16(R16)中引入了条件切换和没有主节点(Master node，MN)参与的辅节点(Secondary node，SN)内的PSCell条件改变，R17中引入了SN间的PSCell条件改变，和条件PSCell添加。
无论是CHO、SN内的PSCell条件改变、SN间的条件PSCell条件改变，或条件PSCell添加，其主要思想都是网络侧设备给UE预配置多个目标小区，即提前将目标小区的配置信息以及执行条件发送给UE。当UE收到目标小区的配置信息后，并不会像传统的切换、PSCell改变(change)或PSCell添加(addition)那样立刻执行切换或PSCell change或PSCell addition，而会将收到的配置保存，并对配置的备选小区进行测量评估，直到存在满足执行条件的小区后，UE则执行存储的该小区对应的重配置消息，进行相应的切换或PSCell change或PSCell addition过程，即完成下行同步并触发随机接入过程接入所述目标PCell或PSCell。
R16只支持网络侧设备单独为UE配置CHO或CPAC，即UE在配置CHO时只判断PCell(Primary Cell，主小区)切换条件是否满足，从而只执行PCell切换过程(也称为条件PCell切换)，即PCell切换过程不伴随PSCell添加或改变，或配置了CPAC时只判断PSCell添加或改变的执行条件是否满足，从而只执行PSCell添加或改变过程，即PSCell添加或改变过程不伴随条件PCell切换过程。
执行条件：
针对CHO，以及R17CPAC，网络可配置类似A3/A5的执行条件：
A3执行条件：候选目标小区的测量质量偏移量优于PCell/PSCell；
A5执行条件：PCell/PSCell的测量质量变得比一预设的绝对门限差，候选目标小区的测量质量变得比另一预设的绝对门限好；
以上这些执行条件都是基于小区级的测量质量指标实现的。
关于CHO和CPAC的现有技术中，当前协议只支持网络侧设备单独配置CHO或CPAC，即UE在执行CHO时只能完成PCell切换，不伴随PSCell添加或改变，即不支持进行条件PCell切换的同时进行PSCell添加或改变。

本申请实施例中，提出在R17或R18中引入CHO与MRDC共存的场景，即带有PSCell添加或改变的条件PCell切换场景，也就是在进行条件PCell 切换的过程中进行PSCell添加或改变的场景。该场景可以实现进行PCell切换的同时建立MRDC，降低建立MRDC的时延，有助于提高网络吞吐量，或在维持PCell连接的同时完成PSCell的移动性管理。
但是，网络如何配置带有PSCell添加或改变的条件PCell切换的配置，以及UE如何基于带有PSCell添加或改变的条件PCell切换的配置来实现PCell的切换，和/或PSCell的改变或添加，是当前需要考虑的一个问题。因此，本申请实施例提供了配置带有PSCell添加或改变的条件PCell切换的方法及装置，用以解决上述问题。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
