其中， 如果终端设备直接与 M2M协调器连接， 则由 M2M协调器对终端设 备的传感网络附着请求进行处理， 并向终端设备发送附着响应消息。 如果终 端设备通过协调器与 M2M协调器连接， 则可能由 M2M协调器对终端设备的传 感网络附着请求进行处理， 或者由协调器对终端设备的传感网络附着请求进 行处理。 由 M2M协调器还是协调器对终端设备的传感网络附着请求进行处理 依据于网络的规则， 如果规则规定由 M2M协调器对终端设备的传感网络附着 请求进行处理，则协调器只需根据 IP标识符确定终端设备请求附着 IP网络后将 该附着请求消息转发给 M2M协调器即可， 如果规则规定由协调器对终端设备 的传感网络附着请求进行处理，则协调器需要根据 IP标识符确定终端设备请求 附着 IP网络后将该附着请求消息转发给 M2M协调器， 同时需要对终端设备的 传感网络附着请求进行处理， M2M协调器收到附着请求消息后， 知道该附着 请求消息是协调器转发的， 则不对终端设备的传感网络附着请求进行处理。
本发明实施例的终端设备直接发出的附着请求消息包括终端设备的传感 网络附着请求信息和 IP标识符， 该 IP标识符表示终端设备是否请求附着 IP网 络， 该附着请求消息能够触发协调器或者 M2M协调器对终端设备的传感网络 附着请求进行处理， 触发边缘路由器对终端设备的 IP网络附着请求进行处理， 使终端设备在传感网络和 IP网络附着时的信令交互过程简化， 节约了网络资 源， 符合低功耗原则。

502、 协调器接收该附着请求消息， 根据 IP标识符确定该终端设备是否请 求附着 IP网络， 如果是， 将该附着请求消息转发给 M2M协调器， 继续执行步 骤 503; 如果否， 则不转发附着请求消息， 对终端设备附着传感网络的请求进 行处理， 向终端设备返回处理结果， 结束本流程。

如果网络规则规定由 M2M协调器对终端设备的传感网络附着请求进行处 理，则该步骤还包括 M2M协调器对终端设备的传感网络附着请求的处理结果； 如果网络规则规定终端设备通过协调器与 M2M协调器连接时， 由协调器对终 端设备的传感网络附着请求进行处理， 则该步骤中 M2M协调器不对终端设备 的传感网络附着请求进行处理。 本发明实施例假定网络规则规定由协调器对 终端设备的传感网络附着请求进行处理。
507、 协调器根据终端设备的附着请求消息， 对终端设备传感网络附着请 求进行处理， 将处理结果加入响应消息后向终端设备发送。
其中， 该步骤并不限于在步骤 506之后执行， 也可以在步骤 502协调器接 收附着请求消息之后执行， 不影响本发明的实现。
其中， 该步骤中对终端设备传感网络附着请求进行处理包括： 对终端设 备进行鉴权； 如果终端设备的附着请求消息中的 Allocate Adress位为 1，则该步 骤中协调器为该终端设备分配用于接入传感网络的普通短地址， 此时处理结 果包括协调器为该终端设备分配的用于接入传感网络的普通短地址。 如果终 端设备的附着请求消息中的 Allocate Adress位为 0时，则该步骤中协调器为该终 端设备分配用于接入传感网络的特殊短地址， 此时处理结果包括协调器为该 终端设备分配的用于接入传感网络的特殊短地址。
