Description

用于双连接中PSCell条件更新的配置方法及装置、存储介质、基站、终端
本申请要求2020年9月29日提交中国专利局、申请号为202011050152.4、发明名称为“用于双连接中PSCell条件更新的配置方法及装置、存储介质、基站、终端”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
本发明涉及通信技术领域，尤其涉及一种用于双连接中PSCell条件更新的配置方法及装置、存储介质、基站、终端。
背景技术
在3GPP的讨论中，协议将引入一种条件切换(Conditional Handover，简称CHO)的机制，请参见图1，图1为现有技术中的一种CHO的示意图。UE当前连接的源小区(也即源基站，Source Node)向候选目标小区(也称候选目标基站，Potential Target Node)发送切换请求(图1所示的CHO请求)，在接收到候选目标小区的确认后(CHO请求ACK)后，向UE发送切换命令，该切换命令中包含切换条件(图1所示的CHO参数)。例如，切换条件可以是当候选目标小区的信号质量比服务小区的信号质量高预定的偏移量，则执行小区切换等。
在用户设备(User Equipment，简称UE)收到切换命令之后，判断候选目标小区是否满足切换条件，若满足，则进行小区切换。具体地，UE利用切换命令中包含的候选目标小区(此时为切换的目标小区)的配置参数，同步到目标小区并执行随机接入流程(图1所示的虚线步骤)，并在该目标小区完成随机接入(Random Access，简称RA)流程后发送切换完成的信令，表征无线资源控制(Radio Resource  Control，简称RRC)重配置完成。由此，UE切换到目标小区。在UE接入目标小区后，目标基站执行路径切换，通知源基站释放该UE的上下文。
另外，如果UE判断不满足切换条件，UE继续维持与源基站的RRC连接(connection)。可选的，源基站可以配置多个候选目标小区以及对应的切换条件(图1未示出)。
在UE收到切换命令之后、尚未切换到目标小区之前，UE继续与源基站保持RRC连接，在这期间，UE继续按照源基站配置的测量配置执行测量，且向源基站上报满足上报条件的邻区。源基站可以依据实际情况随时对切换条件、候选目标小区等进行调整，或者发送非条件切换的切换命令。为此，源基站需要实时掌握UE所处的信道的环境变化，以便及时做出决策，避免由于UE切换到并不合适的邻区而发生连续多次小区切换，从而影响数据传输速率，并影响用户体验。此时UE切换到并不合适的邻区可以指UE切换到并不是某个频率上最强的邻区，切换到非最强邻区之后，UE的上下行信号传输会收到很大的干扰，基站可能做出再次切换的决策。
上述条件切换机制可以应用于双连接中的主辅小区(Primary Secondary Cell，简称PSCell)切换更新(Change)中，此时称为主辅小区条件更新(Conditional PSCell Change，简称CPC)。在双连接中，UE与两个基站，也即主基站(Master Node，简称MN)和辅基站(Secondary Node，简称SN)保持连接，可以同时与这两个基站进行信令和数据的交互。
当PSCell Change中引入条件切换机制时，可以由MN或SN为UE配置PSCell条件更新的配置参数(简称CPC，或者称为CPC配置)。一个CPC配置可以包含一个候选PSCell的标识、该候选PSCell为UE配置的无线参数和PSCell更新条件等。其中，候选PSCell可以为多个，可以由源PSCell向一个或多个候选PSCell发送请求，然后由各个候选PSCell配置后、通过源PSCell发送给UE。更新条件例 如：当候选PSCell的信号质量超过预定门限、或候选PSCell的信号质量比源PSCell的信号质量超过预设的偏移量时，执行PSCell更新。
当MN和SN均为UE配置CPC时，因为每个候选PScell相关的CPC的比特数可能较大，如果两侧配置的CPC太多(也即对应的候选PSCell太多)，很容易超出UE的容量大小，进而影响移动性能，影响用户体验。
由此，亟需一种用于双连接中PSCell条件更新的配置方法，能够确保MN和SN为UE配置的CPC总数不超出UE的容量。

具体实施方式
如背景技术所述，现有的PSCell Change中引入条件切换机制时，由MN或SN为UE配置CPC，可能造成配置的CPC太多，超过UE的容量。
具体而言，请参照图2，给出了本发明实施例中的一种用于双连接中PSCell条件切换(conditional change)的流程图，是主基站为UE配置CPC的流程，以下通过具体步骤进行详细说明。
步骤1：UE建立了双连接。
在Release 15(简称R15)中，存在多制式双连接(Multi-RAT Dual Connectivity，简称MR-DC)。在实际应用中可知，双连接可以存在 不同的类型，如长期演进(Long Term Evolution，简称LTE)双连接、LTE和新空口(New Radio，简称NR)的双连接、NR双连接等。对于LTE和NR的双连接，可以包括EN-DC(LTE基站作为UE的主基站，NR基站作为UE的辅基站)、NE-DC(NR基站作为UE的主基站，LTE基站作为UE的辅基站)、NGEN-DC(连接5G核心网的LTE基站作为UE的主基站、NR基站作为UE的辅基站)。建立双连接的过程属于现有技术，本文不展开叙述，具体可以参考3GPP协议TS37.340。
步骤2：UE按照测量配置执行测量，在满足上报条件时，向网络侧上报测量报告。
在具体实施中，UE可以按照主基站(Master Node，简称MN)配置的测量任务执行测量，然后在有满足上报条件的邻区或服务小区时，向主基站上报测量报告，报告中携带满足上报条件的邻区和/或服务小区的标识和信号质量，也即报告中携带满足上报条件的邻区的标识和信号质量，或者服务小区的标识和信号质量，或者邻区的标识和信号质量以及服务小区的标识和信号质量。
步骤3：主基站依据测量报告，决定执行主辅小区条件更新。
步骤4和4A：主基站选择了一个或多个候选主辅小区，向候选主辅小区所属的基站即候选辅基站发送主辅小区条件更新请求，其中包含主基站侧为UE配置的无线参数，特别包括主基站设定的辅基站配置限制信息(ConfigRestrictInfoSCG)，以及包含UE能力信息和源辅基站为UE配置的无线参数(sourceConfigSCG)等，该请求中还包括主辅小区更新的触发条件(Trigger condition或execution condition)和候选主辅小区标识，该条件可以是UE判断候选主辅小区是否满足更新条件，在满足时，UE执行主辅小区更新(PSCell change或者SN change)。触发条件可以是候选主辅小区的信号质量比源主辅小区的信号质量高预设的偏移量。
需要说明的是，主辅小区条件更新请求可能采用其他名称，如辅 基站条件更新请求。处于双连接的UE可以在辅基站侧配置载波聚合，因此主辅小区条件更新请求并不仅限于PSCell的更新，还可以包含其他辅小区的更新，即候选辅基站可以为UE仅配置候选PSCell的参数，或者可以为UE配置候选PSCell的参数以及一个或多个辅小区的参数。
主基站选择多个候选主辅小区时，可以并行向多个候选辅基站发送主辅小区条件更新请求，也可以先后向多个候选辅基站发送主辅小区条件更新请求。
步骤5和5A：候选辅基站1和候选辅基站2收到主辅小区条件更新请求之后，依据小区负载等做接纳控制，在资源允许的条件下接受更新请求。
步骤6和6A：候选辅基站1和候选辅基站2在接受更新请求之后，为UE分配必要的无线资源，如随机接入资源等，向主基站返回主辅小区条件更新确认，该确认消息中包含为UE配置的无线资源即SCG config。
步骤7：主基站向UE发送主辅小区条件更新的信令，主基站可以通过RRC重配置信令一次发送多个主辅小区条件更新的信息、或者可以采用多条RRC重配置信令依次发送多个主辅小区条件更新的信息。一个主辅小区条件更新信息(即一个CPC配置)包括一个候选主辅小区标识、主辅小区更新的触发条件以及候选辅基站为UE配置的无线资源等。不同的候选主辅小区可以有不同或相同的更新的触发条件。
步骤8：UE收到主辅小区条件更新的信息，开始评估候选主辅小区是否满足更新的触发条件。
步骤9：UE发现至少一个候选主辅小区满足更新的触发条件。如果有多个候选主辅小区满足PSCell更新的触发条件，UE可以选择信号质量最好的候选主辅小区作为更新的目标主辅小区、或者可以随 机选择一个候选主辅小区作为更新的目标主辅小区。
步骤10：UE向主基站指示确定的目标主辅小区，即UE将接入的目标主辅小区，UE可以通过RRC信令向主基站指示确定接入的目标主辅小区，可以指示该小区的标识，主基站收到该指示信息之后，可以提前向目标辅基站前转(forward)UE所建立数据无线承载的数据，以便UE接入目标辅基站之后可以立即接收目标辅基站发送的下行数据。
步骤11：UE通过所确定的目标辅基站为UE配置的无线资源(即目标主辅小区对应的CPC配置中目标辅基站为UE配置的无线参数)，执行随机接入，接入所述目标辅基站。
步骤10和11可以并行执行。步骤10可选。
步骤12：UE接入目标辅基站成功之后，目标辅基站向主基站发送主辅小区更新完成消息。
步骤13和13A：主基站通知源辅基站以及其他候选辅基站释放UE的上下文。
对于双连接中的UE，辅基站也可以为UE配置CPC。综上，现有技术的PSCell条件切换机制中，当MN和SN均可以为UE配置CPC时，因为每个候选PScell相关的CPC的比特数可能较大，如果两侧配置的CPC太多(也即对应的候选PSCell太多)，很容易超出UE的容量大小，超出UE的处理能力。
为解决上述问题，本发明实施例提供一种用于双连接中PSCell条件更新的配置方法，应用于辅基站，所述方法包括：在为UE配置CPC时，判断是否接收到主基站发送的配置门限，所述配置门限为辅基站可配置CPC的数量门限；如果有接收到，则根据所述数量门限确定所述辅基站可配置的CPC数量，所述辅基站可配置的CPC数量小于或等于所述配置门限。
由此，能够确保在双连接中，MN和SN为UE配置的CPC总数 不超出UE的容量。
为使本申请的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本申请的具体实施例做详细的说明。
请参见图3，本发明实施例提供一种用于双连接中PSCell条件更新的配置方法，该方法由SN侧执行，所述方法包括：
步骤S301，在为UE配置CPC时，判断是否接收到主基站发送的配置门限，所述配置门限为辅基站可配置CPC的数量门限；
步骤S302，如果有接收到，则根据所述数量门限确定所述辅基站可配置的CPC数量，所述辅基站可配置的CPC数量小于或等于所述配置门限。
其中，本实施例中的CPC(也可称CPC配置)为候选PSCell的配置参数，可包括层1的配置参数、层2的配置参数、层3的配置参数以及对应的PSCell更新条件等，可选的，每一CPC对应一个候选PSCell。
SN可为UE配置的CPC数量不能超过一定的门限。该门限可由MN配置，即配置门限，配置门限由MN发送至SN。若MN为SN设定了配置门限时，SN可为UE配置的CPC数量小于或等于该配置门限。
可选的，所述方法还包括：接收所述主基站通过辅基站添加请求或辅基站修改请求发送的所述配置门限。
可选的，MN在为UE配置辅小区组(Secondary Cell Group，简称SCG)时，即为UE配置辅小区时，可以向SN发送配置门限；也可以在需要修改SCG参数时向SN发送SN可以配置的CPC数量门限。
具体地，配置门限可在下述两个情况下，由MN发送至SN：
情况1，请继续参见图2，在图2的步骤1，UE建立双连接的过 程中，MN向辅基站发送辅基站添加请求，以便辅基站为UE配置无线参数使得UE接入SN建立双连接。MN在图2的步骤1中，通过辅基站添加请求向SN发送所述配置门限。
情况2，在UE与MN及SN之间建立双连接后，若SCG配置参数发生改变，MN可基于辅基站修改请求向SN发送所述配置门限。
需要说明的是，该配置门限由MN发送至SN的触发情况包括但不限于上述情况。
本实施例中，在SN为UE配置CPC时，使得SN可配置的CPC总数不超出一定的门限，从而为UE配置合理数量的CPC(或CPC配置)，避免超出UE的处理能力，导致UE处理错误，引发通信中断。UE配置了CPC之后，可以评估候选PSCell，在满足候选PSCell的更新执行条件时执行PSCell更新，满足了UE的移动性需求。
可选的，所述配置门限为无主基站参与(without MN involvement)CPC的数量门限和/或主基站参与(MN involvement)的CPC数量门限。
进一步，无主基站参与CPC的数量门限可以为SN内(intra-SN)无主基站参与CPC的数量门限和/或SN间(inter-SN，即不同SN之间)无主基站参与CPC的数量门限。
其中，涉及不同的频带组合(Band combination)或特性集(feature set)的CPC称为MN involvement CPC。处于双连接中的UE，当前辅基站为UE配置的无线参数中包含辅基站为UE配置的频带组合和特性集。候选辅基站为UE配置的无线参数(即CPC配置)中也包含也频带组合和特性集。频带组合表示多个带宽组成的组合，特性集合表示UE在各个带宽上的特性参数的集合。如果CPC中的频带组合或特性集与源辅基站为UE配置的频带组合或特性集不同，此时称为MN involved CPC配置(主基站参与的CPC配置)；如果CPC中的频带组合和特性集与源辅基站为UE配置的频带组合和特性集均相 同，称为without MN involvement CPC配置(无主基站参与的CPC配置，或不需要主基站参与的CPC配置)。
对于intra-SN without MN involvement CPC配置，即SN选择自己所管辖的一个服务小区作为UE的候选PSCell，该候选PSCell为UE配置无线参数，且此时无线参数中的频带组合和特性集与当前PSCell配置的频带组合和特性集均相同，SN可以将CPC配置直接发送给UE。
因为对于MN involvement的CPC配置，通常需要由MN发送给UE。因此MN在为SN设置了without MN involvement CPC配置数量之后，可以控制MN involvement CPC配置数量，确保给UE配置的总CPC的数量不超过UE的容量。
比如，MN设定SN可以配置最多3个无主基站参与的CPC(也即配置门限为3个)，如果协议设定UE最多可以有8个CPC配置，则MN侧可以为UE配置最多5个CPC配置，也即MN involvement CPC最多为5个。或者，MN设定SN可以配置最多3个无主基站参与的CPC和2个主基站参与的CPC，当SN为UE配置了5个CPC之后，假定UE最多可配置8个CPC，MN还可以为UE最多配置3个CPC，这3个CPC均为MN involved CPC或CPC with MN involvement。
在一个实施例中，请继续参见图2，步骤S201中所述判断是否接收到主基站发送的配置门限之后，还可以包括：若未接收到所述配置门限，则根据第一预设门限确定所述辅基站可配置的最大CPC数量。
若SN未接收到MN发送的配置门限，则按照协议规定、或者高层信令配置、或其他预设规则设定的第一预设门限作为SN可为UE配置的CPC的数量门限。也即，SN为UE配置的CPC的数量不超过第一预设门限。例如，第一预设门限为8个CPC，也即如果MN没有为SN设置配置门限，SN可以为UE配置最多8个CPC。
可选的，所述方法还包括：向所述主基站发送CPC数量门限配置请求或CPC数量门限修改请求，以使得所述主基站向所述辅基站发送所述配置门限或更新所述配置门限。
其中，CPC数量门限配置请求为SN向MN发送的、请求配置门限的请求。可选的，若SN未接收到MN发送的配置门限，可向MN发送CPC数量门限配置请求。或者，在SN要为UE配置CPC之前，可向MN发送CPC数量门限配置请求。也即，如果MN没有给SN设置配置门限，SN以第一预设门限为准为UE配置CPC；或者，如果MN没有给SN设置配置门限，SN不能为UE配置CPC，如果需要配置CPC，可向MN发送CPC数量门限配置请求，以触发MN设置。
CPC数量门限修改请求为SN向MN发送的、请求修改配置门限的请求。可选的，在SN要为UE配置CPC之前，可向MN发送CPC数量门限修改请求。或者，若SN发现MN已发送的配置门限不合理(过大或过小)，可向MN发送CPC数量门限修改请求。
本实施例中，SN可向MN发送CPC数量门限配置请求或CPC数量门限修改请求，以使得MN发送/修改配置门限。并且，即使MN未给SN发送配置门限，SN也可根据第一预设门限为UE进行CPC配置。
请参见图4，本发明实施例还提供一种用于双连接中PSCell条件更新的配置方法，该方法由MN侧执行，所述方法包括：
步骤S401，向辅基站发送配置门限，以使得所述辅基站为UE配置CPC时根据所述数量门限确定所述辅基站可配置的CPC数量；
其中，所述配置门限为辅基站可配置CPC的数量门限，所述辅基站可配置的CPC数量小于或等于所述配置门限。
可选的，所述配置门限为无主基站参与CPC的数量门限和/或主基站参与的CPC数量门限。
可选的，所述方法还包括：通过所述辅基站添加请求或辅基站修改请求向所述辅基站发送所述配置门限。
可选的，所述方法还包括：接收所述辅基站发送的CPC数量门限配置请求或CPC数量门限修改请求，并向所述辅基站发送所述配置门限或更新所述配置门限。
关于图4所示方法的其他工作原理、工作方式的更多内容，可以参照图3所述方法中关于MN的相关描述，这里不再赘述。
请参见图5，本发明实施例还提供一种用于双连接中PSCell条件更新的配置方法，该方法由UE侧执行，所述方法包括：
步骤S501，接收辅基站和/或主基站配置的CPC，记作总CPC；
步骤S502，判断总CPC数量是否超过第二预设门限；
如果总CPC数量未超过第二预设门限，也即步骤S502的判断结果为否，执行步骤S503，根据总CPC执行PSCell更新。
如果总CPC数量超过第二预设门限，也即步骤S502的判断结果为是，执行步骤S504，按照预设规则从总CPC中选择若干个CPC，根据选择的CPC执行PSCell更新；
其中，所述辅基站配置的CPC数量小于或等于配置门限，所述配置门限为辅基站可配置CPC的数量门限，所述配置门限由主基站发送至所述辅基站。
UE根据总CPC或选择的CPC执行PSCell更新时，评估总CPC或选择的CPC对应的多个候选PSCell是否满足更新触发条件，若满足，则执行PSCell更新。
对于图5所示的方法，辅基站为UE配置的CPC数量可以不受门限限制，主基站可以不向辅基站发送CPC数量门限，由UE自己按照处理能力选择能够处理的CPC数量。
可选的，所述配置门限为无主基站参与CPC的数量门限和/或主基站参与的CPC数量门限。
可选的，若所述辅基站未接收到所述主基站发送的配置门限，则所述辅基站配置的CPC数量小于或等于第一预设门限。
可选的，所述预设规则包括优先选择最后配置的若干个CPC、优先应用所述主基站配置的CPC、优先应用所述辅基站配置的CPC、优先应用所述辅基站配置的无主基站参与的CPC中的一种。
在双连接中，MN和SN都可以为UE配置CPC，两侧为UE配置的所有CPC，也即总CPC的数量应不超过UE的容量，该容量以第二预设门限表示。可选的，第二预设门限的取值可由协议定义，也可根据UE的处理能力确定，第二预设门限可以与第一预设门限相同或不同。
在总CPC的数量超出第二预设门限时，UE可根据一定的规则(也即预设规则)从总CPC中挑选若干个进行应用，其余不应用。
其中，预设规则可由协议定义、或根据高层信令确定、或者根据UE自己的处理能力和需求来确定。
例如，UE接收两侧发送的CPC配置，收到CPC配置之后，优先应用最后配置的若干个(可以为第二预设门限个)CPC，也即应用最新配置的CPC。
可选的，UE也可以应用最初的若干个CPC。
再例如，UE收到两侧配置的CPC之后，优先应用MN配置的CPC，或优先应用SN配置的CPC，或者，优先应用without MN involvement CPC，只要使得UE应用的CPC数量不超出第二预设门限即可。
可选的，所述按照预设规则从总CPC中选择若干个CPC之后，还包括：删除未被选择的CPC的配置。
也即，未被选择的CPC可被删除，以释放存储空间，提高UE的处理能力。
可选的，若UE通过第二预设门限协调其可被配置的CPC数量，则MN和SN之间可无需协商各自给UE配置的CPC数量。
