实施方式一
请参照图3a，图3a为本申请实施例提供的一种多路径通信方法的流程图之二。如图3a所示，所述方法包括以下步骤：

需要说明地，上述实施方式为终端的发现阶段，终端广播是否支持多路 径通信，以及支持哪种多路径通信规则。上述实施方式中，源端终端(也即UE#1)通过模型(Model)A发现过程来发现目标终端(如UE#2)；在发现阶段之后是连接建立过程，例如，若UE#2决定与UE#1建立直接通信路径或非直接通信(通过中继终端)路径，则UE#2发起向UE#1的连接建立过程。
实施方式二
请参照图3b，图3b为本申请实施例提供的一种多路径通信方法的流程图之三。如图3b所示，所述方法包括以下步骤：
Step1.UE#1广播发现消息，所述发现消息中携带UE#1的多路径通信能力信息，所述多路径通信能力信息包括高层分流功能和低层分流功能中的至少一项；

Step2b.在接收到UE#1的发现消息后，若中继终端决定作为UE#1和UE#2的U2U relay，则U2U relay广播消息中携带UE#1的多路径通信能力信息；
Step3.在UE#2收到U2U relay发送的上述step2b中的发现消息后，如果UE#2决定与UE#1建立非直接通信链路，则发送发现回复消息给U2U relay，所述发现回复消息中携带UE#2的多路径通信能力信息，该多路径通信能力信息也包括高层分流功能和低层分流功能中的至少一项；
Step4.U2U relay在收到上述UE#2的发现回复消息后，将UE#2的多路径通信能力信息通过U2U relay发送的发现回复消息发送给UE#1。
该实施方式同样为终端的发现阶段，源端终端(也即UE#1)通过Model B发现过程来发现目标终端(如UE#2)。进一步地，若UE#2决定与UE#1建立直接通信路径或非直接通信(通过中继终端)路径，则UE#2发起向UE#1的连接建立过程。

Step1.UE#1通过直接建立请求消息携带UE#1的多路径通信信息发送给UE#2；
Step2.UE#2通过直接建立接受消息携带UE#2的多路径通信信息发送给UE#1。
该实施方式中，是在UE#1与UE#2建立连接时，UE#1通过直接建立请求消息将UE#1支持多路径通信通知对端终端，不同于上述实施方式一和实施方式二需要通过发现阶段来通知对端终端。
在发现阶段后，终端能够基于获知的多路径通信能力建立多路径通信连接，以下将通过几个实施方式来介绍终端之间建立多路径通信的具体实施过程。
实施方式四
