若所述标识信息中携带“所述业务类型或传输类型标识信息”,在业务类型或传输类型标识信息为组播时,目标中继终端确定对直接通信接口消息的转发方式为组播,并可进一步的按照组播方式进行转发。在业务类型或传输类型标识信息为广播时,目标中继终端确定对直接通信接口消息的转发方式为广播,并可进一步的按照广播方式进行转发。在业务类型或传输类型标识信息为单播时,目标中继终端确定对直接通信接口消息的转发方式为单播,并可进一步的按照单播方式进行转发。
若所述标识信息中携带“业务是否需要中继的标识信息”,当通过该信息确定业务允许被中继时,目标中继终端确定对直接通信接口消息的转发方式,并可进一步的按照转发方式进行转发。其中,所述目标中继终端确定的转发方式,可以和目标中继终端从第一终端接收到的传输方式相同。
