具体实施方式
下面将结合本发明实施例中的附图, 对本发明实施例中的技术 方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明 一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本 领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他 实施例, 都属于本发明保护的范围。
本发明实施例提供一种 M2M业务消息传输的方法, 如图 1所示, 该方法的执行主体为 MTC ( Machine Type Communications, 机器类 通信) 适配设备, 该方法包括:
S101、 MTC 适配设备获取 CoAP 消息, 并获取所述 CoAP 消息中 的第一标识信息。
其中, 该第一标识信息为该 CoAP消息中标识 CoAP终端的信息, 具体地, MTC 适配设备通过解析该 CoAP 消息, 从而获取该 CoAP 消 息中的 CoAP终端的第一标识信息。
需要说明的是, 上述的 CoAP终端可以包括主终端和至少一个辅 终端, 其中, 主终端支持 3GPP, 辅终端不支持 3GPP 能力 (如没有 SIM 卡的 3GPP 业务), 主终端作为辅终端的代理终端进行消息的中 转, 当然该 Co AP终端也可以只包括主终端。
例如, 该 MTC适配设备可以解析 CoAP 消息中的 Uri- Host 字段 和 Proxy_Uri 字段,从而获得该 CoAP终端的第一标识信息;具体地, 若 CoAP终端的主终端下没有对应的辅终端, 即该 CoAP 消息中不存 在 Proxy- Uri 字段, 则只解析该 CoAP 消息中的 Uri- Host 字段, 从 而获得该 CoAP终端的第一标识信息, 此时, 该 CoAP终端的第一标 识信息可以是该 CoAP终端的主机名称; 若该 CoAP终端的主终端下 对应有辅终端, 即该 CoAP 消息中存在 Proxy-Uri 字段, 则解析该 CoAP消息中的 Ur i_Hos t字段和 Proxy_Ur i 字段, 此时, 该 CoAP终 端的第一标识信息可以是该 CoAP终端的主机名称和该 CoAP终端的 主终端下该 CoAP消息传输的辅终端的标识信息。
可选地, MTC适配设备接收 CoAP服务器发送的 CoAP消息, 进一步地, 上述 CoAP 服务器还可以将 CoAP 消息发送至 TDF ( Traffic Detection Function, 业务检测功能实体), 以便 TDF在 确定接收的消息为 CoAP消息后, 该 MTC适配设备接收该 TDF发送的
CoAP消息。
具体地, TDF 检测到接收的消息中包括以 coap:〃或 coaps: // 开头的 URL ( Univer sa 1 Resource Locator, 统一资源定位符), 则 确定该消息为 CoAP消息。
可选地, 在支持 CoAP协议的 CoAP终端与支持 HTTP ( hypertext transport protocol , 超文本传输协议) 协议的 HTTP服务器交互的 场景下, MTC适配设备接收超文本传送协议 HTTP服务器发送的 HTTP 消息, 因此, 该 MTC 适配设备需要在接收到该 HTTP 消息后, 将该 HTTP消息转换为 CoAP消息。

进一步地, 在确定发送 A组中的 CoAP消息时, 若 MTC适配设备 确定 A组中的 CoAP消息过多,超过了 目 的基站能够承受的最大数量, 则该 MTC适配设备还可以根据 A组中 CoAP消息的应用层中的优先级 消息, 确定同一个组中优先发送的 CoAP消息。
需要说明的是, 这里以传输至相同基站的 CoAP消息为一组作为 分组规则只是举例说明, 具体的分组规则还有很多, 这里就不—— 列举了, 但都应落入本发明的保护范围之内。
