Description

中继选择方法、装置和*** 技术领域
本发明涉及通信领域，特别涉及一种中继选择方法、装置和***。
背景技术
边链路(Sidelink)通信方式是指数据包无需通过核心网和基站，用户1和用户2之间直接建立通信链路，进行通信。在进行边链路通信前，一般会进行发现过程。比如，用户2要通过边链路通信方式发信息给用户1之前，先要发现用户1是否在附近。图1所示为两个用户都在基站覆盖下的发现或建立边链路通信的示意图。图2所示为一个用户在基站覆盖下，另一个用户不在基站覆盖下的发现或建立边链路通信的示意图。图3所示为两个用户都不在基站覆盖下的发现或建立边链路通信的示意图。
边链路通信方式可用于扩大小区覆盖范围。如图1所示，UE2位于小区边缘，信号比较弱，很可能即将离开该小区覆盖，另外，附近有被网络授权的具有中继功能的终端，简称为中继，例如UE1，为了避免业务中断，UE2发现中继UE1后，可以通过该中继UE1接入基站，进行正常的业务通信。如图2所示，UE2位于没有网络覆盖区域，并且，附近有被网络授权的具有中继功能的终端，例如UE1，为了接入网络进行通信，UE2发现位于小区覆盖内的中继UE1后，可以通过该中继UE1接入基站，进行正常的业务通信。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。

实施例1
本发明实施例提供了一种中继选择方法，该方法可以应用于中继设备，例如小区覆盖内的终端设备，基站通过广播或者专用信令配置该终端设备称为中继，通过发现机制，该终端设备能够被某个远程终端选为中继，作为该远程终端的中继设备发挥作用。图5是该方法的流程图，请参照图5，该方法包括：
步骤501：中继设备广播中继发现信息，所述中继发现信息包括所述中继设备的标识信息和所述中继设备所在的服务小区的标识信息。
在本实施例中，该中继设备的标识信息例如为relay UE ID，该中继设备所在的服务小区的标识信息例如为该中继设备所在的服务小区的小区ID，也即cell ID，其中，该小区ID可以使用现有的ECGI(E-UTRAN Cell Global Identifier，E-UTRAN(Evolved UMTS Terrestrial Radio Access Network，演进的UMTS(Universal Mobile Telecommunications System，通用移动通信***)陆地无线接入网)小区全局标识符)、PCI(Physical Cell Identifier，物理小区标识)或其它用于标识小区的ID。
在一个实施方式中，该中继设备可以自主发送上述中继发现信息，在另一个实施方式中，该中继设备可以在接收到远程终端的请求后再发送上述中继发现信息，则在本实施方式中，如图5所示，该方法还可以包括：
步骤500：中继设备接收远程终端发送的中继请求信息。
通过本实施例的方法，远程终端被触发进行中继重选或选择后，可以开始接收上述中继发现信息，进而发现附近的中继设备，具体将在下面的实施例中进行说明。由于该中继发现信息中包含了该中继设备所在的服务小区的标识，有助于基站对远程终端进行必要的配置或下行数据路径转换。
实施例2
本发明实施例提供了一种中继选择方法，该方法应用于远程终端，是对应实施例1的方法的远程终端侧的处理，其中，与实施例1相同的内容不再重复说明。该远程终端可以位于小区覆盖内，也可以没有小区覆盖，其可以通过边链路传输发现中继。图6是该方法的流程图，请参照图6，该方法包括：
步骤601：远程终端接收中继设备发送的中继发现信息，所述中继发现信息包括所述中继设备的标识信息和所述中继设备所在的服务小区的标识信息；
其中，关于中继发现信息，已经在实施例1做了说明，此处省略说明。当远程终端被触发进行中继重选或选择后，该远程终端可以开始接收该中继发现信息，进而发现附近的中继设备。
步骤602：所述远程终端测量发现的中继设备的边链路信道质量；
步骤603：所述远程终端根据测量结果确定所述远程终端的中继设备。
在本实施例中，由于中继发现信息中包含了中继设备所在的服务小区的标识信息，对于小区覆盖范围内(in-coverage)的远程终端，其可以测量发现的所有中继设备的边链路信道质量，从中选择一个合适的中继设备，或者上报给基站，由基站为其选择一个合适的中继设备；或者，其可以仅测量发现的、与自己属于同一个服务小区的中继设备的边链路信道质量，从中选择一个合适的中继设备，或者上报给基站，由基站为其选择一个合适的中继设备。对于小区覆盖范围外(out-of-coverage)的远程终端，其可以测量发现的、与自己的服务中继属于同一个服务小区的中继设备的边链路信道质量，从中选择一个合适的中继设备；或者，其可以测量发现的所有中继设备的边链路信道质量，自主重新选择一个中继设备，并通过服务中继将选择的中继设备的中继信息上报给服务小区(基站)。具体的实施方式将在以下进行说明。
在本实施例的一个场景中，位于邻小区的中继设备不被选择为中继。下面通过该场景下的几个实施方式对本实施例的方法进行说明。
在一个实施方式中，对于小区覆盖范围内的远程终端，如图7所示，步骤602包括：
步骤701：所述远程终端根据所述中继设备所在的服务小区的标识信息，确定与所述远程终端处于同一个服务小区的中继设备；
步骤702：所述远程终端测量发现的、与所述远程终端处于同一服务小区的中继设备的边链路信道质量。

其中，该远程终端可以根据测量结果并参考其它信息，例如负载、电池余量、辅 助量等，从已发现的、与自己处于同一个服务小区的中继设备中选择一个合适的中继设备作为自己的中继。由此，该远程终端可以将选择的中继设备的中继信息上报给基站，该中继信息可以包括选择的该中继设备的标识。基站在接收到该中继信息后，可以向该远程终端反馈确认信息，以确定该远程终端选择的中继设备。
其中，该远程终端也可以将该测量结果发送给基站，由基站为其选择一个合适的中继设备，例如，该远程终端将与该远程终端处于同一个服务小区的中继设备的中继信息上报给基站，在该中继信息中，包含了与该远程终端处于同一个服务小区的中继设备的标识和其测量结果。基于该测量结果，基站可以帮助该远程终端选择一个合适的中继设备并告知该远程终端。由此，该远程终端将基站为其选择的中继设备作为其中继设备。

其中，该远程终端可以根据测量结果并参考其它信息，如前所述，从已发现的、与自己的服务中继处于同一个服务小区的中继设备中选择一个合适的中继设备作为自己的中继。由此，该远程终端可以将选择的中继设备的中继信息上报给其服务中继，由其服务中继把该中继信息转发给服务小区(基站)。其中，该中继信息可以包括选择的该中继设备的标识。基站在接收到该中继信息后，可以向该服务中继反馈确认信息，由该服务中继将该确认信息转发给该远程终端，以确定该远程终端选择的中继设备。
在本实施例的另一个场景中，位于邻小区的中继设备也可以被选择为中继。下面通过该场景下的几个实施方式对本实施例的方法进行说明。

其中，该远程终端可以根据测量结果和其它信息(如前所述)从发现的所有中继设备中选择一个合适的中继设备作为自己的中继，并把选择的中继设备的中继信息上报给基站，其中，该中继信息可以包括选择的中继设备的标识和该中继设备所在的服务小区的标识。
其中，该远程终端也可以将该测量结果上报给基站，由基站为其选择一个合适的中继设备。例如，该远程终端将发现的所有中继设备的中继信息上报给基站，在该中继信息中，包含了发现的所有中继设备的标识、各中继设备对应的测量结果以及各中继设备所在的服务小区的标识。基于该测量结果，基站可以帮助该远程终端选择一个合适的中继设备。由此，该远程终端将基站为其选择的中继设备作为其中继设备。
其中，由于选择的中继设备(远程终端自己选的或者基站为其选的)和该远程终端可能属于同一服务小区，也可能属于不同的服务小区，对于基站侧的处理过程，将在实施例3中进行说明。
在另一个实施方式中，对于小区覆盖范围外的远程终端，其测量的也是发现的所有中继设备的边链路信道质量，与前一实施方式不同的是，由于该远程终端处于小区范围外，没有服务小区，其可以根据测量结果和其它信息(如前所述)从发现的所有中继设备中自主选择一个中继设备作为自己的中继设备，并将选择的中继设备的中继信息发送给自己的服务中继，通过自己的服务中继将选择的中继设备的中继信息发送给服务小区(基站)。其中，该中继信息可以包括选择的中继设备的标识和该中继设备所在的服务小区的标识。
图9是本实施方式的小区覆盖范围外的远程终端的中继选择过程的示意图，如图9所示，假设小区覆盖范围外的远程终端已经连接到中继1，随着该远程终端向右移动，越来越靠近位于邻小区的中继2，在中继重选过程中，该远程终端会自主重选一个中继设备，在图9的示例中，该远程终端会重选到中继2，并把选中的中继设备(中继2)的中继信息通过中继1发送给服务小区(小区1)，该中继信息可以包括中继2的标识和该中继2所在的服务小区(小区2)的标识。
