894EAW RTSP协议 10554
894EAW 私有协议 18000
…… …… ……
设备3中的每个服务对应一个服务类型，服务对应的服务类型可以是该服务对应的协议类型。例如，服务类型可以为RTSP、超文本传输协议(hyperText transfer protocol，HTTP)和私有协议，RTSP、HTTP和私有协议分别与设备3中的RTSP服务、Web服务和私有协议服务一一对应。
参见图1，代理服务器2中保存有设备标识、服务类型与第一标识的对应关系22和P2P模块21。设备3包括P2P模块31和至少一个服务模块32，每个服务模块32用于提供服务。对于每个服务模块，该服务模块与该服务模块提供的服务对应的服务类型相对应。例如，图2所示的设备3中包括Web服务模块321、RTSP服务模块322和私有协议模块323，Web服务模块321用于提供Web服务，与服务类型“HTTP”相对应；RTSP服务模块322用于提供RTSP服务，与服务类型“RTSP”相对应；私有协议模块323用于提供私有协议服务，与服务类型“私有协议”相对应。
参见图2，该通信系统还可以包括报警中心4，报警中心4可以与每个设备3和每个终端1相连。设备3可以向报警中心4报警，报警中心4可以通知终端1，使终端1请求与设备3通信。
例如，设备3可以是安装在家中的摄像头或门禁系统等，可以提供视频监控等服务，设备3在检测到有人员闯入时向报警中心4发送报警，报警中心4可以向终端1发送通知，该通知包括设备3的设备标识，终端1可以为手机或电脑等终端。
终端1可以在接收该通知后，向代理服务器2发送查询请求，该查询请求携带设备3的设备标识和终端1请求的服务对应的服务类型。代理服务器2接收该查询请求，根据该查询请求携带的设备的设备标识和服务类型，从设备标识、服务类型与第一标识的对应关系中获取对应的第一标识，向终端1发送查询响应，该查询响应携带该第一标识。
可选的，终端1接收该查询响应后，可以与代理服务器2之间可以建立用于传输该服务类型对应服务的第一连接。

作为一种示例，代理服务器2可以保存有设备标识与链路标识的对应关系，该对应关系中的每条记录包括一设备标识和代理服务器2与该一设备标识对应的设备之间当前存在的P2P链路的链路标识。例如，参见下表2所示的设备标识与链路标识的对应关系，该对应关系中的P2P链路的链路标识可以是该P2P链路对应的端口号，该端口号是该P2P链路在代理服务器2中对应的端口的端口号，该端口是P2P链路在代理服务器2侧的端点。

在本申请实施例中，接收模块接收终端发送的第一报文时，确定模块分配用于标识终端和终端请求的服务的第二标识，保存模块将第二标识、该设备标识、第一连接的连接标识保存在第二标识、设备标识与连接标识的对应关系中。这样在发送模块通过该P2P链路向该设备发送包括第二标识、服务类型和第一数据的第二报文后，如果接收模块接收到该设备返回的携带有该设备标识和第二标识的报文，则可以基于该设备标识和第二标识获取到第一连接的连接标识，从而基于该连接标识对应的第一连接向该终端发送该报文。如此可以通过第二标识区别在代理服务器与设备之间的P2P链路上传输的终端请求的多个服务或多个终端请求的服务，如此设备只需要建立一条P2P链路即可，避免了给设备建立大量的P2P链路，进而避免网络延时增加的现象发生。
