随机接入的处理方法、装置及终端
相关申请的交叉引用
本申请主张在2021年05月08日在中国提交的中国专利申请No.202110502356.5的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种随机接入的处理方法、装置及终端。
背景技术
双连接(Dual Connectivity，DC)，即为终端提供两个网络节点(接入网网元)的资源，其中一个网络节点称为主节点(Master Node，MN)，另一个称为辅节点(Secondary Node，SN)。在每个网络节点，使用了载波聚合技术(Carrier Aggregation，CA)，即为终端配置由该节点控制的一系列服务小区，也称为小区组(cell group)。主节点控制的为主小区组(Master Cell Group，MCG)，辅节点控制的为辅小区组(Secondary Cell Group，SCG)。每个小区组都包含一个特殊小区(Special Cell，SpCell)和一系列辅小区(Secondary Cell，Scell)。在MCG中特殊小区称为主小区(Primary Cell，PCell)，在SCG中特殊小区称为主辅小区(Primary Secondary Cell，PSCell)。在一个小区组中SpCell使用主载波，而其他辅小区使用辅载波。
引入了SCG挂起(suspended)状态，当终端很长一段时间在SCG上都是低数据传输时或者没有数据传输时，网络可以将SCG暂时挂起，而不是直接将SCG删除然后等较大数据出现时再添加回来。将SCG暂时挂起的做法，可以使终端在较长一段时间内以更加省电的方式工作，同时当有大量数据需求时可以较快地恢复SCG。在标准化过程中，使用了SCG去激活(SCG deactivation)的说法，即SCG激活/去激活状态。SCG去激活也可以是处于终端过热(overheating)或者省电目的来启动。目前正在讨论SCG去激活态时的终端行为和网络控制方式等，可以确定的是在SCG去激活期间，终端不 监听SCG上的物理下行控制信道(Physical Downlink Control Channel，PDCCH)且不进行物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、信道探测参考信号(Sounding Reference Signal，SRS)传输。对于SCG期间的其他终端行为，部分行为会受到限制以省终端功耗，另一部分行为可能可以继续执行以加快SCG激活以尽快开始进行数据传输。
但是目前存在下述至少两种场景，分别为：
场景1，当终端已经触发了随机接入时，而网络侧同时给终端发送SCG去激活命令；
场景2，在SCG去激活态，终端请求激活SCG时，可以通过在SCG上发起随机接入的方式，若终端在SCG上已经发起了随机接入，而同时网络侧给终端发送了用于触发一个新的随机接入的配置信息。
上述两种场景导致了终端可能执行不必要的随机接入，导致终端无谓的耗电。或者终端执行不必要的SCG去激活操作，不符合终端当前对SCG状态的需求。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的随机接入的处理方法、装置及终端进行详细地说明。
如图2所示，本申请实施例提供一种随机接入的处理方法，包括：
步骤101，终端在辅小区组SCG上进行第一随机接入的过程中，若满足第一条件，所述终端执行第一操作；其中，所述第一条件包括下述至少一项：所述终端发起第二随机接入；所述终端接收到第一配置信息；所述终端接收到所述SCG去激活命令；所述第一配置信息用于触发带宽部分(bandwidth Part，BWP)切换和/或第三随机接入；
其中，所述第一操作为以下之一：
继续进行所述第一随机接入；
停止进行所述第一随机接入。
本申请实施例中，在满足第一条件的情况下，终端是继续进行所述第一随机接入，还是停止进行所述第一随机接入，可以由网络配置决定，也可以由预先设定的条件确定；其中，相关条件可以由网络设定，也可以由协议约定，或者终端与网络预先预定，在此不做具体限定。
需要说明的是，终端在SCG上进行第一随机接入时，SCG可以处于激活态，也可以处于去激活态，在此不做具体限定。例如，SCG处于激活态，终端在主辅小区PSCell或SCG辅小区上发起第一随机接入；再例如，SCG处于去激活态，有上行数据到达SCG，终端请求激活SCG，则终端在PSCell上发起第一随机接入。
在本申请的至少一个实施例中，在所述第一条件为所述终端发起所述第二随机接入的情况下，
所述第一随机接入和所述第二随机接入中至少之一是所述终端在SCG处于去激活态时所触发的。
例如，若第一随机接入是终端在SCG处于激活态时触发的，则第二随机接入可以是终端在SCG处于激活态时触发的，也可以是终端在SCG处于去激活态时触发的；再例如，若第一随机接入是终端在SCG处于去激活态时触发的，而第二随机接入也是终端在SCG处于去激活态时触发的。
作为本申请的一个可选实施例，步骤201中所述终端在辅小区组SCG上进行第一随机接入的过程中，若所述终端发起第二随机接入，所述终端停止进行所述第一随机接入，包括：
若所述第二随机接入是由执行条件主辅小区变更(Conditional PSCell  Change，CPC)所触发的，在满足第二条件的情况下，所述终端停止进行所述第一随机接入；可选地，终端停止进行所述第一随机接入后，所述终端可继续进行所述第二随机接入。
其中，所述第二条件包括以下至少一项：
所述第一随机接入是所述终端在所述SCG处于去激活态时由上行数据到达所述SCG所触发的；
所述第一随机接入是所述终端在所述SCG处于去激活态时由上行数据到达所述SCG而所述SCG上行失步所触发的；
所述第一随机接入是所述终端在所述SCG处于去激活态时由上行数据到达所述SCG而所述终端没有用于发送调度请求(scheduling request，SR)的上行资源所触发的；
所述第一随机接入是由波束失败恢复(Beam Failure Recovery，BFR)所触发的。
一种实施例为，终端在SCG处于去激活态时，由于上行数据到达SCG，终端在SCG上发起第一随机接入请求激活SCG，在这个过程中终端持续进行条件PSCell变更的评估、执行，从而在CPC执行条件满足时触发了第二随机接入。由于执行CPC导致终端切换到了新的目标PSCell，那么终端就没有必要在原来的源PSCell上发起随机接入，故而终端停止第一随机接入，发起第二随机接入。
作为本申请的至少一个可选实施例，步骤201中所述终端在辅小区组SCG上进行第一随机接入的过程中，若所述终端接收到所述SCG去激活命令，所述终端执行所述第一操作，包括：
在满足第三条件的情况下，所述终端执行所述第一操作；其中，所述第三条件包括下述至少一项：
所述第一随机接入是由上行数据到达所述SCG而所述终端的SCG上行失步所触发的；
所述第一随机接入是由上行数据到达所述SCG而所述终端没有用于发送SR的上行资源所触发的；
所述第一随机接入是由终端请求激活所述SCG所触发的；
所述第一随机接入是由SCG的SR失败所触发的；
所述第一随机接入是由BFR所触发的；
所述第一随机接入是由执行CPC所触发的；
所述第一随机接入是由建立，辅时间提前组(secondary Timing Advance Group，sTAG)的时间对齐(Time Alignment，TA)所触发的。
需要说明的是，所述终端在辅小区组SCG上进行第一随机接入的过程中，若所述终端接收到所述SCG去激活命令，至少包括：
SCG处于激活态，终端在SCG上进行第一随机接入的过程中，终端接收到SCG去激活命令；
SCG处于去激活态，终端在SCG上进行第一随机接入的过程中，终端接收到SCG去激活命令；例如终端发生了切换且无PSCell更改(handover without PSCell change)，目标主节点决定将SCG保持为去激活态，则目标主节点向终端发送SCG去激活命令。
作为一个可选实施例，在所述第三条件包括下述至少一项的情况下，所述终端继续执行所述第一随机接入：
所述第一随机接入是由终端请求激活所述SCG所触发的；
所述第一随机接入是由SCG的SR失败所触发的；
所述第一随机接入是由上行数据到达所述SCG而所述终端的SCG上行失步所触发的；
所述第一随机接入是由上行数据到达所述SCG而所述终端没有用于发送SR的上行资源所触发的。
作为另一个可选实施例，在所述第三条件包括下述至少一项的情况下，所述终端停止执行所述第一随机接入：
所述第一随机接入是由BFR所触发的；
所述第一随机接入是由执行CPC所触发的；
所述第一随机接入是由建立sTAG的TA所触发的。
作为另一个可选实施例，若所述第三条件是在SCG激活态时所触发的，所述终端继续执行所述第一随机接入，若所述第三条件是在SCG去激活态时所触发的，所述终端停止执行所述第一随机接入。
例如SCG处于激活态时，终端有待发送的上行数据，在没有物理上行控制信道(Physical Uplink Control Channel，PUCCH)/PUSCH资源的情况下终端需要发起随机接入来申请上行传输资源，在这一过程中，网络侧可能由于网络资源紧张从而给终端发送了SCG去激活命令。因此，终端可以停止发起随机接入，避免在发起随机接入后网络侧需要再次发送SCG去激活命令。
再如SCG处于去激活态时，终端由于上行数据到达SCG从而在SCG上发起了随机接入，在这一过程中，终端发生了切换，由于目标主基站和辅基站不知道终端此时是否有上行数据要发送，目标主基站可能会给终端发送SCG去激活命令让终端保持SCG在去激活态。因此，终端可以继续发起随机接入，从而通知网络侧终端有待传输的上行数据。
再如，若SCG处于激活态时触发了CPC执行，那么终端会发起随机接入，该随机接入可能是在目标PSCell给UE配置的专有随机接入资源上发起的，若终端在该随机接入期间收到了SCG去激活命令，那么终端应该优先完成第一随机接入，然后可选地，将SCG去激活，或者不去激活SCG，等待目标PSCell决定是否将SCG去激活。
再如，若SCG处于去激活态时触发CPC执行，终端发起随机接入，该随机接入可能是竞争随机接入，即不是在专有随机接入资源上发起的。那么终端可以先不发起随机接入，等到SCG被激活时再发起随机接入。
在本申请的至少一个可选实施例中，在所述第一条件为所述终端接收到SCG去激活命令的情况下，
若所述第一操作为继续进行所述第一随机接入，所述方法还包括：
所述终端忽略所述SCG去激活命令，或所述终端在所述第一随机接入完成后将所述SCG去激活；
或者，若所述第一操作为停止进行所述第一随机接入，所述方法还包括：
所述终端根据所述SCG去激活命令，将所述SCG去激活。
作为本申请的至少一个可选实施例，步骤201中所述终端在辅小区组SCG上进行第一随机接入的过程中，若所述终端接收到所述第一配置信息，所述终端停止进行所述第一随机接入，包括：
在满足第四条件的情况下，所述终端停止进行所述第一随机接入；
其中，所述第四条件包括下述至少一项：
所述第一配置信息中包括专用随机接入资源；
所述第一配置信息触发了主辅小区变化(PSCell change)；
所述第一配置信息触发了SCG激活。
其中，所述终端接收到所述第一配置信息包括：
所述终端在所述SCG处于去激活态的情况下接收到所述第一配置信息。
作为本申请一个可选实施例，所述终端在辅小区组SCG上进行第一随机接入的过程中，若所述终端接收到所述第一配置信息，所述终端停止进行所述第一随机接入之后，所述方法还包括下述至少一项：
所述终端根据所述第一配置信息执行BWP切换；
所述终端根据所述第一配置信息发起第三随机接入；
所述终端根据所述第一配置信息执行BWP切换，并在切换后的BWP上发起随机接入。
作为本申请的另一个可选实施例，所述终端在辅小区组SCG上进行第一随机接入的过程中，若所述终端接收到所述第一配置信息，所述终端继续进行所述第一随机接入之后，所述方法还包括：
不执行所述BWP切换；或者，
在所述第一随机接入完成后执行所述BWP切换。
在本申请实施例中，终端在辅小区组SCG上进行第一随机接入的过程中，若满足第一条件，终端继续进行所述第一随机接入或者停止进行所述第一随机接入；可以避免终端执行不必要的随机接入从而导致的终端耗电增加和SCG激活时延增加；或者避免终端执行不必要的SCG去激活，满足终端自身的SCG激活/去激活需求。
