如图1所示，通信系统100可以包括终端110和网络设备120。网络设备120可以通过空口与终端110通信。终端110和网络设备120之间支持多业务传输。

为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
关于小区内终端的数据传输
通常情况下，如图2所示，在一个小区内会存在多个终端同时工作，网络对每个终端进行单独配置，不同的终端占据不同的时频资源，终端在相应的时频资源上各自完成数据传输，相互之间没有关联。
对于每个终端来说，通常其具备的发射或接收链路都是有限的，比如一般终端在一个频段会具有两个发射链路和四个接收链路。这就意味着，该终端在上行发射中最多可以采用两个数据流，在下行接收中最多可以采用四个数据流。此外，对于一个小区来说，其可用的总工作带宽也是有限的，比如当信道带宽为100MHz时，其可用的频域资源就固定为100MHz，小区内同时工作的所有终端共享这100MHz的资源。因此，平均到每个终端，其在一个时刻可用的资源是非常少的。这也就导致了终端的最大上行发射速率是有限的。当有大量数据需要发送或接收时，终端的上下行速率就难以满足需求。
由于一个小区内的终端之间是相互没有关联的，每个终端都是独立进行自身的数据传输，一个终端仅能靠自身的收发能力来完成数据的接收及发送。然而，由于小区内用户数量众多，单个终端能分配到的时频资源是非常有限的，这限制了终端的数据传输速率的提升。因此，如何进一步优化小区内多终端场景下的终端数据传输是需要解决的问题。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
单个终端的数据传输能力往往难以满足终端的数据传输速率要求，一种进一步提升数据传输速率的方式是终端间的协作数据传输，也可以称为多终端联合传输。
在图2中，终端1和终端3是有数据需要传输的终端，他们分别占据了不同的时频资源，此时终端2处于空闲状态并没有数据需要传输，但终端2本身是具备进行数据传输的硬件资源，比如发射链路和接收链路等。因此，在图2的基础上可以考虑将终端2加以利用。如图3所示，假设终端1此时有大量的数据需要在短时间内完成传输，但仅仅依靠其本身具有的收发能力以及网络分配的时频资源是无法在短时间内完成数据传输的。此时，可以考虑借用终端2具备的收发能力来跟中1一起进行数据传输。假设终端1和终端2分别具备2个发射链路和4个接收链路，也即分别具备发射2个数据流和接收4个数据流。那么当终端1和终端2构成终端组合(也可以称为虚拟终端)同时用于传输时，其收发能力将增加到发射4个数据流和接收8个数据流。这将成倍的增加收发能力。
这里，当前进行业务的终端为终端1(后面简称为主终端或需求终端)。对于终端2是分享数据传输能力的终端(在后面简称为辅终端或共享终端)。其中，数据传输能力有多种，比如上行多进多出(Multiple In Multiple Out，MIMO)能力、下行MIMO能力、载波能力、发射功率能力等。
在这种多终端联合传输模式下，如何处理终端组合的移动性需要明确。本申请以下实施例提供一种移动性控制方法，具体地，该方法是一种多终端联合传输场景下的终端组合的移动性控制方法。
需要说明的是，本申请实施例中，终端组合包括多个终端，多个终端形成的终端组合也可以称为虚拟终端。
需要说明的是，本申请实施例中，联合传输也可以称为数据共享传输。
需要说明的是，本申请实施例中，终端组合中的主终端是指有需求进行数据发送和/或数据接收的终端，主终端也可以称为需求终端。
需要说明的是，本申请实施例中，终端组合中的辅终端是指分享数据传输能力的终端，辅终端也可以称为共享终端。
图4是本申请实施例提供的一种移动性控制方法的流程示意图一，如图4所示，所述移动性控制方法包括以下步骤：
步骤401：第一终端向第一基站发送第一请求消息，第一基站接收第一请求消息，所述第一请求消息用于请求所述第一基站对终端组合进行变更，所述终端组合用于联合传输。
步骤402：所述第一基站基于所述第一请求消息，对所述终端组合进行变更。
本申请实施例中，所述终端组合包括主终端和至少一个辅终端，所述终端组合用于联合传输所述主终端的数据。
在一些可选实施方式中，对于上行传输来说，主终端和至少一个辅终端将来自主终端的数据联合传输给网络，其中，辅终端侧的数据是由主终端转发给辅终端的。
在一些可选实施方式中，对于下行传输来说，网络将针对主终端的数据发送给主终端和至少一个辅终端，其中，至少一个辅终端中的每个辅终端将接收到的数据转发给主终端。
本申请实施例中，终端组合由于某些情况的出现而导致该终端组合不能够继续实现联合传输，这种情况下，需要对终端组合进行变更。这里，导致终端组合进行变更的情况包括但不局限于：终端组合中的一个或多个终端进行了移动。以下结合不同的方案对如何进行终端组合的变更进行说明。

图5是本申请实施例提供的一种移动性控制方法的流程示意图二，如图5所示，所述移动性控制方法包括以下步骤：
步骤501：第一基站接收第一终端发送的切换请求消息。
步骤502：所述第一基站将所述第一终端关联的终端组合的信息发送给第二基站；所述终端组合用于联合传输。
本申请实施例中，所述终端组合包括主终端和至少一个辅终端，所述终端组合用于联合传输所述主终端的数据。
在一些可选实施方式中，对于上行传输来说，主终端和至少一个辅终端将来自主终端的数据联合传输给网络，其中，辅终端侧的数据是由主终端转发给辅终端的。
在一些可选实施方式中，对于下行传输来说，网络将针对主终端的数据发送给主终端和至少一个辅终端，其中，至少一个辅终端中的每个辅终端将接收到的数据转发给主终端。
本申请实施例中，所述第一基站和所述第二基站联合为所述终端组合提供通信服务。这种情况下，所述主终端和所述至少一个辅终端中的至少部分终端从所述第一基站覆盖的第一小区移动至第二基站覆盖的第二小区情况下，由于所述第一基站和所述第二基站可以联合为所述终端组合提供通信服务，因此终端组合不会发生变更，但是需要第一基站将终端组合的信息发送给第二基站，如此，第二基站可以根据终端组合的信息配合第一基站联合为终端组合提供通信服务。
上述方案中，所述至少部分终端由于从第一小区移动至第二小区，因而可以将这部分终端称为切换终端。其中，所述至少部分终端包括所述第一终端。在一些可选实施方式中，所述第一终端为所述主终端；或者，所述第一终端为所述至少部分终端中的一个辅终端。
需要说明的是，上述方案，是一种小区间移动性控制的方案，且终端组合与多个基站保持联系。
需要说明的是，本申请实施例中描述的“第一基站”是指移动过程中的“原基站”。本申请实施例中描述的“第二基站”是指移动过程中的“目标基站”。
以下结合具体应用实例对本申请实施例的技术方案进行举例说明。
应用实例一
如图6所示，在小区内终端1和终端2构成终端组合，终端1为主终端，终端2为辅终端，终端2为终端1提供辅助数据传输服务。由于终端在小区内具有移动性及其自身业务情况的变化(如终端2在一段时间后距离终端1比较远，难以为终端1提供数据传输服务，或终端2有自身的数据需要传输而无法为终端1提供服务等)，很可能会导致终端2无法继续为终端1提供数据传输服务。因此需要变更终端1关联的终端组合。
具体地，终端1与终端2构成的终端组合进行数据联合传输过程中，如果终端2不合适继续作为辅终端，则需要更新终端组合：
方式一：主终端发起终端组合重配置请求
1)辅终端在组成终端组合后，发射辅终端标识信号。
这里，辅终端标识信号用于主终端识别辅终端，以及测量主终端与辅终端间的距离或传播损耗。可选地，辅终端标识信号包括以下至少之一：辅终端的标识信息、辅终端的发射功率强度信息、辅终端的地理位置信息。
2)主终端测量辅终端标识信号，根据测量结果得到主终端与辅终端间的距离或传播损耗。
3)若主终端与辅终端间的距离或传播损耗大于或等于一定门限，主终端向基站发送终端组合重配置请求。
这里，门限可以为网络配置的，也可以为主终端自主设定的，也可以为约定值。
这里，主终端与辅终端间的距离或传播损耗大于或等于一定门限，表明该辅终端已不再适合为主终端提供数据传输服务，主终端向基站发送终端组合重配置请求。
4)基站将辅终端(即终端2)从终端组合中移除。
图7是本申请实施例提供的一种移动性控制方法的流程示意图，如图7所示，包括以下步骤：
步骤701：主终端向基站发送终端组合重配置请求消息。

这里，所述通知消息用于通知辅终端从终端组合中移除。
步骤703：基站向主终端发送终端组合重配置确认消息。
这里，所述组合重配置确认消息用于指示基站确认已将辅终端(即终端2)从终端组合中移除。
方式二：辅终端发起终端组合重配置请求
1)当辅终端无法继续为主终端提供数据传输服务时，辅终端向基站发起终端组合重配置请求。
2)基站将辅终端(即终端2)从终端组合中移除。
图8是本申请实施例提供的一种移动性控制方法的流程示意图，如图8所示，包括以下步骤：

这里，所述组合重配置确认消息用于指示基站确认已将辅终端(即终端2)从终端组合中移除。
应用实例二
当终端组合在多个小区间进行移动时，将发生小区间的移动性管理问题。典型的场景包括主终端从小区1移动到小区2，以及辅终端从小区1移动到小区2。
方案一：主终端从小区1移动到小区2
如图9所示，主终端(即终端1)从小区1(即基站1覆盖的小区)进入小区2(即基站2覆盖的小区)并进行小区间切换，而辅终端(即终端2)则依然保留在小区1内。在这种情况下，对终端组合的一种处理方式是解除终端1作为主终端的所有终端组合。当终端1进入小区2后，终端1将向基站2重新发起终端组合请求，以在小区2建立新的终端组合。
图10是本申请实施例提供的一种移动性控制方法的流程示意图，如图10所示，包括以下步骤：
步骤1001：主终端向基站发送终端组合重配置请求消息。
这里，终端组合重配置请求携带第三信息，所述第三信息用于指示解除小区1内的终端1作为主终端的所有终端组合。
步骤1002：基站将辅终端从终端组合中移除，并向辅终端发送通知消息。
这里，所述通知消息用于通知辅终端从终端组合中移除。
步骤1003：基站向主终端发送终端组合重配置确认消息。
这里，所述组合重配置确认消息用于指示基站确认已将主终端的所有终端组合解除。
在一些可选实施方式中，除了主终端(即终端1)从小区1进入小区2以外，还有部分的辅终端也从小区1移动到了小区2。如图11所示，主终端(即终端1)和辅终端(即终端2)从小区1(即基站1覆盖的小区)进入小区2(即基站2覆盖的小区)并进行小区间切换，而辅终端(即终端3)则依然保留在小区1内。在这种情况下，保留跟主终端一起切换的辅终端所构成的终端组合，而仅移除不跟主终端一起切换的辅终端。具体地，当主终端(即终端1)和辅终端(即终端2)都移动到小区2，而辅终端(即终端3)仍处于小区1时，保持终端1与终端2的终端组合，并将该终端组合一起切换到基站2下面，并在基站2下面进行终端组合的联合传输，而将终端3从终端组合中移除。这种方式可以尽可能的保持主终端的通信速率。
方案二：辅终端从小区1移动到小区2
如图12所示，辅终端(即终端2)从小区1(即基站1覆盖的小区)进入小区2(即基站2覆盖的小区)并进行小区间切换，而主终端(即终端1)则依然保留在小区1内。在这种情况下，对 终端组合的一种处理方式是将辅终端(即终端2)从终端组合中移除(当存在多个辅终端时，位于小区1内的其余辅终端依旧保留在终端组合内)。
图13是本申请实施例提供的一种移动性控制方法的流程示意图，如图10所示，包括以下步骤：
步骤1301：辅终端向基站发送终端组合重配置请求消息。
这里，终端组合重配置请求携带第七信息，所述第七信息用于指示将辅终端(即终端2)从终端组合中移除。
这里，所述第七信息用于指示将辅终端(即终端2)从小区1内的特定终端组合中移除或者从小区1内的全部终端组合中移除。

这里，所述组合重配置确认消息用于指示基站确认已将辅终端(即终端2)从终端组合中移除。
应用实例三
多个基站为终端组合同时保持连接的情况下，终端组合在小区间移动时可以保持终端组合不变。在终端组合移动过程中，进入新小区的终端接入新基站后将与新基站进行通信，而保留在原小区的终端则继续接入原基站并与原基站进行通信。其中，新基站从原基站获取进入新小区的终端所属的终端组合的信息，以继续进行终端组合的联合传输。
如图14所示，辅终端(即终端2)从小区1(即基站1覆盖的小区)进入小区2(即基站2覆盖的小区)并进行小区间切换，辅终端(即终端2)作为切换终端。
如图15所示，主终端(即终端1)从小区1(即基站1覆盖的小区)进入小区2(即基站2覆盖的小区)并进行小区间切换，主终端(即终端1)作为切换终端。
