Description

一种条件主辅小区添加或改变的方法、装置和存储介质
相关申请的交叉引用
本申请基于申请号为202110762183.0、申请日为2021年07月06日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及移动通信技术领域，尤其涉及一种条件主辅小区添加或改变的方法、装置和存储介质。
背景技术
条件主辅小区添加或改变(Conditional PSCell Addition or Change，CPA或CPC)是网络侧主节点(MN)或辅节点(SN)提前把主辅小区(Primary Secondary Cell，PScell)添加或改变的条件发给终端，当终端测量到目标PSCell满足条件时自发进行PSCell添加或改变的过程。
目前，只要用户设备(UE)发现目标PSCell满足添加或改变的条件，就会与该PSCell建立RRC连接，激活该小区进行双连接。实际应用中，网络侧MN或SN根据UE的业务特点，判断UE可能很快需要进行双连接，但不是当前就需要，而待UE需要进行双连接时，再添加PSCell又非常耗时(约几十ms时延)，不利于快速为UE提供高数据速率的服务。
发明内容
有鉴于此，本发明实施例期望提供一种条件主辅小区添加或改变的方法、装置和存储介质。
为达到上述目的，本发明实施例的技术方案是这样实现的：

下面结合场景实施例对本发明进行描述。
本实施例提出一种可不立刻激活PSCell的CPA或CPC机制，网络侧MN或SN给UE配置主辅小区添加或改变的条件，并指示UE发现目标PSCell满足添加或改变的条件后，是否立刻激活PSCell，或激活PSCell的时间或条件等，可在节省UE的功耗和信令开销的前提下，快速恢复双连接，为UE提供高数据速率的服务。
本实施例的实现流程如下，包括：
步骤一：网络侧节点MN或SN配置UE条件主辅小区添加或改变(CPA或CPC)的信息，如：A3、A5、A4、B1中的一项或两项和相应的门限值，具体内容可参见相关技术，此处不再详述；此外，在配置上述内容时还可指示如下一种或几种信息：
1)发现满足添加或改变的条件的目标PSCell后，是否立刻激活该PSCell；或者，激活该PSCell的时间(如相对收到该配置信息的时刻的时间偏移)，该时间可以是所有候选PSCell相同、也可以是per PSCell配置的；或者，激活该PSCell的概率；
这里，MN或SN可基于对UE业务的特点的判断来配置激活该PSCell的时间，如：MN或SN预测UE一定时间内不会有高数据速率的业务到达，因此认为这段时间不用激活PSCell。
MN或SN可基于对UE之前的业务的特点的判断来配置激活该PSCell的概率，如：MN或SN预测UE一定概率不会有高数据速率的业务到达，因此认为一定概率不用激活PSCell。
2)是否允许UE主动发起激活PSCell的请求，如果允许，向MN发起还是向SN发起；例如：当UE有上行业务需求时，需要主动发起激活PSCell的请求；
3)激活该PSCell的条件，如UE发起了预设业务，如：特殊的slice(如超可靠低延迟通信(URLLC))业务时，UE的(上行UL或下行DL)数据包数目或数据大于或不小于第一阈值；和/或UE的数据包的时延大于或不小于第二阈值；和/或UE的业务格式信息指示的数据包长度大于或不小于第三阈值的业务数据的到达时间或所述业务数据到达后的持续时间长度等。
步骤二：UE根据网络侧节点MN或SN配置的CPA或CPC信息，发现某PSCell满足条件，并建立与该PSCell的RRC连接；
步骤三：UE根据步骤一中配置的指示信息，判断是否激活该PSCell；具体的，可包括如下一种或多种：
1)若网络侧除上述CPA或CPC的信息之外没有配置其他指示信息，则默认激活所述PSCell；
2)若网络侧指示不(立刻)激活PSCell，则将该PSCell处于去激活状态，即UE不监听(monitor)PDCCH，可以放松RRM测量等；
3)若网络侧配置了激活该PSCell的时间，则在满足网络要求的时刻起激活该PSCell(通过向MN或SN发起激活请求)，在此之前不激活；
4)若网络侧配置了激活该PSCell的概率P，在UE随机产生一个0,1之间的随机数p(所述UE可在与所述PSCell建立RRC连接之后产生所述随机数p)，并与概率P进行比较；若p小于或不大于概率P，则激活PSCell，反之则不激活；
5)若网络侧配置了激活该PSCell的条件，则UE判断是否满足，满足的话则激活该PScell。
步骤四：UE向MN或SN上报已与某目标PSCell建立RRC连接，状态为激活或去激活。
可选的，该方法还可包括：
步骤五：若UE因业务需要需主动激活PSCell，则根据网络侧的配置，向MN或SN发起激活请求；所述激活请求可携带预激活的PSCell的相关ID，如PCI；还可携带激活的原因等。
本发明实施例在UE发现目标PSCell满足添加或改变的条件后可先与PSCell建立连接(如RRC连接)，之后再基于激活指示信息进行是否激活PSCell的判断，在业务需要时可马上激活PSCell，不需要时，则不进行PSCell的激活。因此，与相关技术待UE需要进行双连接时，再添加PSCell又非常耗时(约几十ms时延)的技术相比，本发明实施例可在节省UE的功耗和信令开销的前提下，可快速恢复双连接(如在RRC已连接的基础上直接激活即可)，为UE快速提供高数据速率的服务；与UE与PSCell建立RRC连接后立即激活该PSCell小区进行双连接的技术相比，本发明实施例可在UE的业务并不需要立刻双连接的场景下，节省UE的功耗(因为双连接的功耗比单连接大一些)。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。
