具体实施方式
本公开实施例提供一种随机接入发起方法、通信设备、通信系统及存储介质。
第一方面，提供一种随机接入发起方法，其中，由终端执行，方法包括：根据终端的至少一个服务小区非连续发送DTX以及非连续接收DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入。
基于上述方案，终端会根据至少一个服务小区非连续发送DTX以及非连续接收DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入，而非在统一在有第一业务传输的情况下就统一发起随机接入，从而减少终端不必要的随机接入，也减少因为终端不必要随机接入使得小区退出DTX和/或DRX导致的网络功耗，和/或第一业务的传输延时。
在第一方面的一些实施例中，根据终端的至少一个服务小区非连续发送DTX以及非连续接收DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入，包括以下至少之一： 在终端的至少一个服务小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入；在终端的至少一个服务小区有配置DTX以及DRX的至少其中之一时，根据终端的至少一个服务小区配置的DTX以及DRX的至少其中之一的激活情况，确定是否发起因第一业务触发的随机接入。
基于上述方案，在终端至少一个服务小区未配置DTX以及DRX时，则说明终端至少有一个服务小区可正常工作，因此终端可以在该小区上执行第一业务的传输，因此无需执行因第一业务发起的随机接入。
在终端的服务小区有配置DRX和/或DRX的情况下，还可以进一步根据DRX和/或DRX的激活情况，确定是否需要发起因第一业务触发的随机接入。
在第一方面的一些实施例中，至少一个服务小区包括主小区(Primary cell，Pcell)和辅小区(Secondary cell，Scell)；主小区所在的小区组为主小区组(Master cell group，MCG)；根据终端的至少一个服务小区非连续发送DTX以及非连续接收DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入，包括以下至少之一：根据终端的主小区DTX以及DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入；根据终端的各服务小区DTX以及DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入；根据终端的主小区组MCG中各服务小区DTX以及DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入。
基于上述方案，前述第一小区可为主小区、终端的所有服务小区或者MCG中的各服务小区中的一个或多个，如此，后续在确定是否发起随机接入时可以根据需要灵活选择。
在第一方面的一些实施例中，根据终端的主小区DTX以及DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入，包括以下至少之一：在主小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入；在主小区有配置DTX以及DRX的至少其中之一时，根据主小区的DTX以及DRX的至少其中之一的激活情况，确定是否发起因第一业务触发的随机接入。
基于上述方案，主小区同时未配置DRX和DTX，则说明主小区随时可以向终端提供通信服务，因此终端有第一业务待传输，可以直接在主小区进行第一业务的传输，无需发起因第一业务触发的随机接入。在主小区配置有DRX和DTX的至少其中之一时，则会根据主小区配置的DTX和/或DRX的激活情况，进一步确定是否需要发起第一业务对应的随机接入。
在第一方面的一些实施例中，在主小区有配置DTX以及DRX的至少其中之一时，根据主小区的DTX以及DRX的至少其中之一的激活情况，确定是否发起因第一业务触发的随机接入，包括：在主小区有配置DTX以及DRX至少其中之一且主小区DTX以及DRX的至少其中之一被激活，根据当前时刻是否处于主小区DTX和/或DTX的非激活时段，确定是否发起因第一业务触发的随机接入；在主小区有配置DTX以及DRX至少其中之一且主小区DTX以及DRX未被激活，确定不发起因第一业务触发的随机接入。
基于上述方案，在主小区的DRX和DRX至少其中之一被激活，则还会进一步根据当前时段是否处于主小区激活的DTX和/或DRX的非激活时段，确定是否发起因第一业务触发的随机接入，从而可以进一步减少终端不必要的随机接入。
在第一方面的一些实施例中，在主小区有配置DTX以及DRX至少其中之一且主小区DTX以及DRX的至少其中之一被激活，根据当前时刻是否处于主小区DTX和/或DTX的非激活时段，确定是否发起因第一业务触发的随机接入，包括以下至少之一：在主小区有配置DTX以及DRX的至少其中之一、主小区DTX以及DRX的至少其中之一被激活且当前时刻处于主小区DTX和/或DRX的非激活时段，确定发起因第一业务触发的随机接入；在主小区有配置DTX以及DRX的至少其中之一、主小区DTX以及DRX的至少其中之一被激活且当前时刻处于主小区DTX和/或DRX的激活时段，确定不发起因第一业务触发的随机接入。
基于上述方案，在当前时刻处于主小区DTX和/或DRX的非激活时段，则说明终端无法在主小区上通信，故此时可以通过随机接入的发起使得主小区可以向终端提供第一业务相关的通信服务。
在第一方面的一些实施例中，根据终端的各服务小区DTX以及DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入，包括以下至少之一：在终端存在一个服务小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入；在终端各服务小区均有配置DTX以及DRX的至少其中之一且在终端各服务小区中存在至少一个服务小区DTX以及DRX未被激活时，确定不发起因第一业务触发的随机接入；在终端各服务小区均有配置DTX以及DRX的至少其中之一且在终端各服务小区DTX以及DRX的至少其中之一均被激活时，根据当前时刻是否至少一个服务小区DTX和/或DRX的激活时段，确定发起因第一业务触发的随机接入。
基于上述方案，终端的至少一个服务小区同时未配置DRX和DTX的情况下，则该小区可用于向终端提供第一业务的通信服务，因此终端可以在该同时未配置DRX和DTX的小区上执行第一业务的传输，终端无需执行因第一业务触发的随机接入。
在第一方面的一些实施例中，在终端存在一个服务小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入，包括：在终端存在一个辅小区未配置DTX以及DRX、未配置DTX以及DRX的辅小区处于激活态且激活的带宽部分BWP不是休眠BWP时，确定不发起因第一业务触发的随机接入。
基于上述方案，终端同时未配置DTX以及DRX的服务小区是服务小区，则还需确定该服务小区是否处于激活态，若该辅小区处于激活态且使用的激活BWP不是休眠BWP，则说明该辅小区有极高的概率为终端提供第一业务传输相关的通信服务，如此终端无需发起因第一业务触发的随机接入，进而可以减少不必要的随机接入。
在第一方面的一些实施例中，在终端各服务小区均有配置DTX以及DRX的至少其中之一，在终端各服务小区DTX以及DRX的至少其中之一均被激活时，根据当前时刻是否至少一个服务小区DTX和/或DRX的激活时段，确定发起因第一业务触发的随机接入，包括以下至少之一：在终端各服务小区均有配置DTX以及DRX的至少其中之一、在终端各服务小区DTX以及DRX的至少其中之一均被激活且当前时刻是至少一个服务小区DTX和/或DRX的激活时段时，确定不发起因第一业务触发的随机接入；在终端各服务小区均有配置DTX以及DRX的至少其中之一，在终端各服务小区DTX以及DRX的至少其中之一均被激活且当前时刻不是任意一个服务小区DTX和/或DRX的非激活时段时，确定发起因第一业务触发的随机接入。
基于上述方案，终端还会根据当前时刻是否处于各服务小区的DTX和/或DRX的激活时段，确定是否需要发起因第一业务触发的随机接入。
在第一方面的一些实施例中，根据终端的主小区组MCG各服务小区DTX以及DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入，包括以下至少之一：在终端MCG存在一个服务小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入；在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一时，根据MCG中各服务小区DTX以及DRX至少之一的激活情况，确定是否发起因第一业务触发的随机接入。
基于上述方案，根据MCG中各服务小区的DTX以及DRX的配置情况，确定是否发起因第一业务触发的随机接入，也可以减少不必要的随机接入。
在第一方面的一些实施例中，在终端MCG存在一个服务小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入，包括：在终端MCG存在一个辅小区未配置DTX以及DRX、未配置DTX以及DRX的辅小区处于激活态且激活的带宽部分BWP不是休眠BWP时，确定不发起因第一业务触发的随机接入。
在第一方面的一些实施例中，在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一时，根据MCG中各服务小区DTX以及DRX至少之一的激活情况，确定是否发起因第一业务触发的随机接入，包括以下至少之一：在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一且MCG中至少一个服务小区DTX以及DRX未被激活时，确定不发起因第一业务触发的随机接入；在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一且MCG中各服务小区DTX以及DRX至少之一被激活时，根据当前时刻是否处于MCG中各服务小区的DTX和/或DRX的激活时段，确定是否发起因第一业务触发的随机接入。
基于上述方案，在当前时刻不是任意MCG中任意服务小区的DTX和/或DRX的激活时段，则确定是否发起因第一业务触发的随机接入，可以再次减少不必要的随机接入。
在第一方面的一些实施例中，在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一且MCG中各服务小区DTX以及DRX至少之一被激活时，根据当前时刻是否处于MCG中各服务小区的DTX和/或DRX的激活时段，确定是否发起因第一业务触发的随机接入，包括以下至少之一：在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一、MCG中各服务小区DTX以及DRX至少之一被激活且当前时刻处于MCG中至少一个服务小区的DTX和/或DRX的激活时段时，确定不发起因第一业务触发的随机接入；在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一、MCG中各服务小区DTX以及DRX至少之一被激活且当前时刻处于MCG中各服务小区的DTX和/或DRX的非激活时段，确定发起因第一业务触发的随机接入。
在第一方面的一些实施例中，第一业务包括：紧急呼叫业务。
第二方面，提供一种终端，其中，终端包括：处理模块，被配置为根据终端的至少一个服务小 区非连续发送DTX以及非连续接收DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入。
第三方面，本公开实施例提供一种通信设备，通信设备包括：一个或多个处理器；其中，处理器用于调用指令以使得通信设备执行第一方面的可选实现方式所描述的随机接入发起方法。
第四方面，本公开实施例提供了一种存储介质，其中，存储介质存储有指令，当指令在通信设备上运行时，使得通信设备执行第一方面的可选实现方式所描述的随机接入发起方法。

下述本公开实施例可以应用于图1A所示的通信系统100、或部分主体，但不限于此。图1A所示的各主体是例示，通信系统可以包括图1A中的全部或部分主体，也可以包括图1A以外的其他主体，各主体数量和形态为任意，各主体之间的连接关系是例示，各主体之间可以不连接也可以连接，其连接可以是任意方式，可以是直接连接也可以是间接连接，可以是有线连接也可以是无线连接。

有鉴于此，如图2所示，本公开实施例提供一种随机接入发起方法，由通信系统执行。该方法可包括：
S2101：终端确定是否发起因第一业务触发的随机接入。
在一些实施例中，第一业务可为任意指定的业务。
在一些实施例中，第一业务可为任意延时容忍度小于指定值的业务。
在一些实施例中，第一业务至少包括紧急呼叫业务。
在一些实施例中，该第一业务可为终端作为主叫端紧急呼叫其他终端的业务。
在一些实施例中，该随机接入可包括：四步随机接入和/或两步随机接入。
在一些实施例中，该随机接入可为：基于竞争的随机接入和/或非竞争的随机接入。
在一些实施例中，根据终端的至少一个服务小区非连续发送DTX以及非连续接收DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入。
在一些实施例中，配置情况可指明终端的至少一个服务小区是否有配置DTX和/或DRX。
在一些实施例中，若一个服务小区配置有DTX且DTX被激活，则服务小区在DTX的激活时段执行下行发送，在DTX的非激活时段不执行下行发送。在服务小区DTX的非激活时段不执行下行发送时，则服务小区可进入到节省能耗的低功耗状态。
示例性地，如图1B所示，小区DTX对应的DTX周期。一个DTX周期可包括激活时段(active period)和非激活时段(non-active period)。
在一些实施例中，若一个服务小区的DRX被激活，则服务小区在DRX的激活时段执行上行接收，在DRX的非激活时段不执行上行接收。在服务小区DRX的非激活时段不执行上行接收时，则服务小区可进入到节省能耗的低功耗状态。
示例性地，如图1C所示，小区DRX对应的DRX周期。一个DRX周期可包括激活时段(active period)和非激活时段(non-active period)。
在一些实施例中，终端支持载波聚合、双连接或多连接。在这种情况下，终端可具有多个服务小区。终端这些服务小区可包括：主小区和辅小区。
在一些实施例中，辅小区又可以包括：主辅小区和普通的辅小区。
在一些实施例中，前述至少一个服务小区可包括：主小区、主辅小区和/或普通的辅小区。
在一些实施例中，S2101：在终端的至少一个服务小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入。
如果终端的至少一个服务小区未配置DTX以及DRX的至少其中之一，则终端有第一业务待传输时，则可以直接在该未配置DTX以及DRX的至少其中之一的服务小区上执行第一业务的传输，从而减少终端发起不必要的随机接入，也减少其他有配置DRX以及DRX的小区因为接受终端的随机接入所产生的功耗。
在一些实施例中，S2101：在终端的至少一个服务小区有配置DTX以及DRX的至少其中之一时，根据终端的至少一个服务小区配置的DTX以及DRX的至少其中之一的激活情况，确定是否发起因第一业务触发的随机接入。
在一些实施例中，激活情况可指明终端的至少一个服务小区的DTX和/或DRX是否有被激活。
在一些实施例中，S2101可包括：
根据终端的主小区DTX以及DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入；主小区为终端的服务小区之一。
在一些实施例中，在主小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入。
由于终端的主小区都未配置DTX和/或DRX，则相当于主小区一直可以向终端提供服务，则终端在有第一业务相关的传输时，无需通过随机接入再进行第一业务传输，一方面可以减少终端不必要的随机接入，另一方面也可以减少终端不必要随机接入引入的第一业务传输延时。
在一些实施例中，在主小区有配置DTX以及DRX的至少其中之一时，根据主小区的DTX以及DRX的至少其中之一的激活情况，确定是否发起因第一业务触发的随机接入。
主小区的DTX以及DRX的激活情况可反映主小区的DTX以及DRX是否被激活。若主小区的DTX以及DRX被激活，则主小区可能在DTX和/或DRX的非激活时段不执行下行发送和/或上行接收，如此可能会使得终端的第一业务传输受阻。在这种情况下，将根据主小区的DTX和/或DRX的激活情况，确定是否发起因第一业务触发的随机接入，以尽可能节省小区和/或满足第一业务传输的延时要求。
在一些实施例中，在主小区有配置DTX以及DRX至少其中之一且主小区DTX以及DRX的至少其中之一被激活，则可以不管当前时段是否处于于主小区DTX和/或DTX的非激活时段，都可以确定发起因第一业务触发的随机接入。
在一些实施例中，在主小区有配置DTX以及DRX至少其中之一且主小区DTX以及DRX的至少其中之一被激活，根据当前时刻是否处于主小区DTX和/或DTX的非激活时段，确定是否发起因第一业务触发的随机接入。
进一步地，在主小区有配置DTX以及DRX的至少其中之一、主小区DTX以及DRX的至少其中之一被激活且当前时刻处于主小区DTX和/或DRX的非激活时段，确定发起因第一业务触发的随机接入；
在主小区有配置DTX以及DRX的至少其中之一、主小区DTX以及DRX的至少其中之一被激活且当前时刻处于主小区DTX和/或DRX的激活时段，确定不发起因第一业务触发的随机接入。
在一些实施例中，该当前时刻可理解为确定有带传输第一业务的时刻。
在一些实施例中，该当前时刻可为接收到上层发起的第一业务的时刻。
在一些实施例中，该当前时刻可为接收到上层发起的紧急业务的时刻。
在一些实施例中，终端MAC层有收到上层发起第一业务的时刻。在一些实施例中，该上层可包括但不限于应用层和/或非接入层。
若当前时刻处于主小区DTX和/或DRX的非激活时段，则可能还需要持续一段时间主小区才会进入到DTX和/或DRX的激活时段。此时为了满足第一业务的延时要求，则确定发起随机接入。如此小区在收到终端随机接入情况之后，可通过退出小区DTX和/或DRX的方式满足终端第一业务传输的延时要求。或者，小区在接收到随机接入之后，可以在不退出小区DTX和/或DRX的情况下配置满足终端第一业务传输的通信资源，以满足终端第一业务传输的延时要求。
若当前时刻处于主小区DTX和/或DRX的激活时段，则终端可以在激活时段内进行第一业务的传输，则可以无需发起随机接入，从而减少不必要的随机接入且减少因为随机接入引入的延时。
在一些实施例中，S2101可包括：根据终端的各服务小区DTX以及DRX的至少其中之一的配置情况，确定是否发起因第一业务触发的随机接入。
在一些实施例中，若终端支持载波聚合和/或双连接，则终端的服务小区可能有多个。
在一些实施例中，在终端存在一个服务小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入。
在一些实施例中，终端未配置DTX以及DRX的至少其中之一的服务小区是辅小区时，该辅小区被激活且有执行非休眠(non-dormancy)行为时，则说明该辅小区可供终端执行第一业务的传输，则确定终端不发起因第一业务触发的随机接入。
辅小区可被激活或去激活。若辅小区去激活则说明该辅小区未被激活，此时辅小区不收发终端的数据。因此，在确保未配置DTX和/或DRX的辅小区被激活且未执行休眠的情况下，确定第一业务触发的随机接入。
在一些实施例中，该小区执行非休眠行为则代表终端的激活BWP不是休眠(dormancy)BWP。若该辅小区的激活BWP是休眠BWP。休眠BWP为休眠状态的BWP，休眠状态的BWP可不用于数据传输。
在这种情况下，如果终端有至少一个服务小区未配置DTX和/或DRX，则终端就不用发起因第一业务触发的随机接入，而是直接在该未配置DTX和/或DRX的服务小区上执行第一业务的传输。
在终端各服务小区均有配置DTX以及DRX的至少其中之一且在终端各服务小区中存在至少一个服务小区DTX以及DRX未被激活时，确定不发起因第一业务触发的随机接入。
在一些实施例中，若终端的各个服务小区都被配置了DTXD和/或DRX，则确定终端是否有至少一个服务小区的服务小区DTX和/或DRX未激活，若存在一个服务小区的DTX和/或DRX未被激活，则终端可以使用该DTX和/或DRX未被激活的小区上进行第一业务的传输，则无需发起因第一业务触发的随机接入。
在一些实施例中，在终端各服务小区均有配置DTX以及DRX的至少其中之一且在终端各服务小区DTX以及DRX的至少其中之一均被激活时，确定发起因第一业务触发的随机接入。
在这种情况下，由于终端各个服务小区DTX和/或DRX都被激活，为了实现简便，则可以确定终端发起因第一业务触发的随机接入。
在一些实施例中，在终端各服务小区均有配置DTX以及DRX的至少其中之一且在终端各服务小区DTX以及DRX的至少其中之一均被激活时，根据当前时刻是否至少一个服务小区DTX和/或DRX的激活时段，确定发起因第一业务触发的随机接入。
此处的当前时刻的相关描述可以参见前述实施例，此处就不再重复了。
在一个实施例中，在终端各服务小区均有配置DTX以及DRX的至少其中之一、在终端各服务小区DTX以及DRX的至少其中之一均被激活且当前时刻是至少一个服务小区DTX和/或DRX的激活时段时，确定不发起因第一业务触发的随机接入。
在当前时刻是至少一个服务小区的DTX和/或DRX的激活时段，则终端可以在处于小区DTX和/或DRX的激活时段的小区上执行第一业务的传输，而无需发起因第一业务触发的随机接入。
在一些实施例中，在终端各服务小区均有配置DTX以及DRX的至少其中之一，在终端各服务小区DTX以及DRX的至少其中之一均被激活且当前时刻不是任意一个服务小区DTX和/或DRX的非激活时段时，确定发起因第一业务触发的随机接入。
在当前时刻未处于任意一个服务小区DTX和/或DRX的激活时段时，则通过随机接入的发起，使得至少一个服务小区退出DTX和/或DRX，或者为终端配置传输第一业务的资源，以满足第一业务的传输需求。
在一些实施例中，S2101可包括：在终端MCG存在一个服务小区未配置DTX以及DRX时，确定不发起因第一业务触发的随机接入。
在一些实施例中，MCG为终端主小区所在的小区组。在这种情况下无需关注终端的辅小区组。
若MCG中存在至少一个服务小区未配置小区DTX和/或小区DRX，则终端可在该小区执行第一业务的传输，则无需发起因第一业务触发的随机接入。
在一些实施例中，MCG包括主小区和辅小区，若未配置DTX以及DRX的至少其中之一的小区为辅小区，则辅小区被激活且有执行非休眠(non-dormancy)行为时，则说明该辅小区可供终端执行第一业务的传输，则确定终端不发起因第一业务触发的随机接入。
在一些实施例中，该小区执行非休眠行为则代表终端的激活BWP不是休眠(dormancy)BWP。
在一些实施例中，S2101可包括：在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一时，根据MCG中各服务小区DTX以及DRX至少之一的激活情况，确定是否发起因第一业务触发的随机接入。
在MCG中各服务小区都有配置DTX以及DRX的情况下，则需要根据MCG中各服务小区的DTX和/或DRX的激活情况，确定是否需要发起因第一业务触发的随机接入，则可以减少终端不便要的随机接入的同时确保第一业务的及时传输。
在一些实施例中，在MCG中各服务小区都有配置DTX以及DRX的情况下，则MCG中至少一个服务小区DTX以及DRX中的至少其中之一未被激活，则可确定不发起因第一业务触发的随机接入。
在一些实施例中，在MCG中各服务小区都有配置DTX以及DRX的情况下，则MCG中至少一个服务小区DTX以及DRX中的至少其中之一均被激活，则可确定发起因第一业务触发的随机接入。
在一些实施例中，在MCG中各服务小区都有配置DTX以及DRX的情况下，则MCG中至少一个服务小区DTX以及DRX中的至少其中之一均被激活，根据当前时段是否处于MCG中各服务小区的DTX和/或DRX的激活时段，确定是否发起因第一业务触发的随机接入。在这种实施例中，可以进一步减少终端发起不必要的随机接入。
在一些实施例中，在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一、MCG中各服务小区DTX以及DRX至少之一被激活且当前时刻处于MCG中至少一个服务小区的DTX和/或DRX的激活时段时，确定不发起因第一业务触发的随机接入；
在终端MCG各个服务小区均有配置DTX以及DRX的至少其中之一、MCG中各服务小区DTX以及DRX至少之一被激活且当前时刻处于MCG中各服务小区的DTX和/或DRX的非激活时段，确定发起因第一业务触发的随机接入。
在一些实施例中，MCG还可以是替代为指定小区组。该指定小区组可为包含主辅小区的小区组。即根据指定小区组中各服务小区是否有配置DTX以及DRX的至少其中之一，确定是否发起因第一业务触发的随机接入。根据指定小区组中各服务小区未配置DTX以及DRX的至少其中之一，确定不发起因第一业务触发的随机接入。根据指定小区组中各服务小区有配置DTX以及DRX的至少其中之一，根据指定小区组中各服务小区的DTX和/或DRX的激活情况和/或当前时段是否位于指定小区组各服务小区DTX和/或DRX的激活时段，确定不发起因第一业务触发的随机接入。
S2102：终端发起随机接入。
在一些实施例中，在确定发起随机接入时，发起随机接入。
在一些实施例中，终端的主小区、主辅小区或者其他普通的辅小区上发起随机接入。
如图3所示，本公开实施例提供一种随机接入发起方法，由终端执行。该方法包括：
S3101：确定是否发起因第一业务触发的随机接入。
在一些实施例中，该S3101的可选实施例可参见图2对应实施例的S2101，此处就不重复了。
S3102：发起随机接入。
在一些实施例中，该S3102的可选实施例可参见图2对应实施例的S2102，此处就不重复了。
值得注意的是：S3102为可选步骤，例如，在S3101中确定不发起因第一业务触发的随机接入时，则无需执行S3102。
在(Carrier Aggregation，CA)场景下或多无线接入技术双连接(Multi-(Radio Access technology,RAT)Dual Connectivity，MR-DC)场景，如果存在一个服务小区没有配置小区DTX/DRX(简称DTX/DRX)，或者配置的小区DTX/DRX没有激活的话，则可以正常进行紧急呼叫(emergency call)业务，特别是主小区(pcell)没有激活或者没有配置小区DTX/DRX的话，更不需要执行随机接入信道(Random Access Channel，RACH)RACH过程来满足紧急呼叫(emergency call)业务。
此处RACH过程即为终端的随机接入过程。RACH过程以下提供几个可以减少终端不必要的随机接入，提出了如下方式中的一个或多个：
方式1：
如果PCell的cell DTX和/或cell DRX处于激活态，和/或当前时段处在主小区DTX和/或DRX的非激活(non-active)时段，如果此时终端发起紧急呼叫业务，则终端发起RACH过程，否则不用为emergency call发起RACH过程。
方式2：
选项1：如果不存在任何同时满足如下两个条件的服务小区，则发起RACH过程，否则不用为emergency call发起RACH过程；
条件1：处于Scell激活态且non-dormancy；辅小区non-dormancy则说明辅小区无休眠行为，也即辅小区的激活BWP不是休眠(dormant)BWP。
条件2：cell DTX和/或cell DRX处于去激活态，或者cell DTX和/或cell DRX没有配置。
选项2：如果MCG侧不存在同时满足如下条件的任何一个服务小区，则发起RACH过程，否则不用为emergency call发起RACH过程：
条件1：处于Scell激活态且非休眠(non-dormancy)。辅小区non-dormancy则说明辅小区的激活BWP不是休眠(dormant)BWP。
条件2：cell DTX和/或cell DRX处于去激活态，或者cell DTX和/或cell DRX没有配置。
如果此时终端发起紧急呼叫业务，则终端发起RACH过程，否则不用为emergency call发起RACH过程。
总之，基于PCell的小区DTX/DRX配置状态或者激活态，判断是否为emergency call发起RACH过程。示例性地，对于PCell，如果同时没有配置小区DTX(简称DTX)和小区DRX(简称DRX)、或者有配置小区DTX和/或DRX未被激活，则不触发RACH，否则触发RACH过程。
基于全部服务小区的小区DTX/DRX配置状态或者激活态，综合判断是否为紧急呼叫业务发起RACH过程。示例性地，如果存在一个服务小区同时没有配置小区DTX和DRX，或者配置的DTX和/或DRX都没有被激活，且该小区为辅小区时该辅小区处于激活态且非休眠，则可以不用触发RACH过程，否则触发RACH过程。
