Description

移动性事件处理方法、装置、通信设备及存储介质 技术领域
本公开涉及但不限于通信技术领域,尤其涉及一种移动性事件处理方法、装置、通信设备及存储介质。
背景技术
在第五代移动通信技术(5th Generation Mobile Communication Technology,5G)系统中,引入了双连接(Dual Connectivity,DC)架构。该DC构架中包括两个小区组,其中一个为主小区组(Master Cell Group,MCG),一个为辅小区组(Secondary Cell Group,SCG)。在当前5G系统中,当用户设备(User Equipment,UE)支持DC时,只能在MCG或者SCG中任意一个小区组获得移动性管理操作技术带来的移动性增益,如更低的切换失败概率等;如此影响了UE的移动性性能。

为了便于本领域内技术人员理解,本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然,本领域内技术人员可以理解,本公开实施例提供的多个实施例,可以被单独执行,也可以与本公开实施例中其他实施例的方法结合后一起被执行,还可以单独或结合后 与其他相关技术中的一些方法一起被执行;本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案,首先,对相关技术中进行部分说明:
在一些实施例中,双连接架构中包括两个小区组:MCG和SCG;其中,MCG对应网络侧主节点(Master Node,MN);SCG对应网络侧辅节点(Secondary Node,SN)。这里,MCG包括一个主小区(Primary Cell,PCell)和至少一个辅小区(Secondary Cell,SCell);SCG包括一个主辅小区(Primary Secondary Cell,PSCell)和至少一个辅小区(Secondary Cell,SCell)。这里,PCell和PSCell可统称为特殊小区(Special Cell,SpCell)。
在一些实施例中,UE可基于预配置条件执行移动性管理操作;这里预配置条件包括:测量对象和/或触发事件。例如,UE当测量对象满足触发事件时,则触发事件作为预配置条件。这里,移动性管理操作,包括:基于触发事件触发的移动性过程。该基于触发事件触发的移动过程包括以下至少之一:条件切换(Conditional Handover,CHO)、条件主辅小区添加(Conditional PSCell Additio,CPA)以及条件主辅小区变更(Conditional PSCell Change,CPC)。
在另一些实施例中,UE可基于预配置条件执行移动性管理操作。这里,移动性管理操作包括:选择性激活小区组。网络侧可以给UE提供预配置的小区组;网络侧后续可以通过激活信令将该预配置的小区组激活或者去激活,而不用再重新提供小区组的配置。这里,该预配置的小区组也可以通过触发事件触发的方式进行激活或者去激活。
在一些实施例中,网络侧给UE配置针对特定的测量事件;当UE满足该测量事件时自行网络侧配置的行为(例如上报测量结果或者触发切换等)。
这里,测量对象主要包括但不限于以下至少之一:测量频点、测量小区及测量的无线接入技术。这里,测量频点包括但不限于绝对无线频率信道编号(Absolute Radio Frequency Channel Number,ARFCN)。这里,测量小区包括但不限于物理小区标识(Physical Cell Identifier,PCI)。这里,测量的无线接入技术包括但不限于5G NR、4G LTE及3G UTRA的其中之一。
