这里, 所述合适的承载网络是指: 根据本地 CSE的预先配置的策略选 择的承载网络, 比如: 从某个应用预先设定的资费的角度考虑, 所选择的 承载网络类别。 例如, 有些应用被设定只使用有线网络和 wifi 网络, 而有 些应用被设定为使用有线网络、 wifi网络和 3G网络。
步骤 303: 本地 CSE检测所述已查找到的合适的承载网络是否连接到 目标 CSE, 如果是, 则通过所述承载网络发送 M2M应用请求; 否则, 执行 步骤 304;
其中, 所述本地 CSE通过所述承载网络发送 M2M应用请求, 包括: 如果本地 CSE检测到已有合适的承载网络连接到目标 CSE, 则立即发 送 M2M应用请求到目标 CSE;
优选的, 发送成功后, 本地 CSE还将发送 M2M应用请求发送成功的 反馈给所述 M2M应用;
如果本地 CSE检测到有多个合适的承载网络连接到目标 CSE, 则根据 请求类别对应的合适的承载网络列表的排序选择排在最前面的承载网络发 送请求。 其中, 所述承载网络列表位于所述请求类别配置表中。
步骤 304:如果本地 CSE没有检测到合适的承载网络连接到目标 CSE, 则读取请求消息中的请求发送延迟时间的值, 根据该值进行承载网络的尝 试连接, 成功连接后, 发送 M2M应用请求到目标 CSE; 这里, 如果本地 CSE读取的请求发送延迟时间的值为 0, 则本地 CSE 立即根据该请求的请求类型对应的承载网络建立与目标 CSE的连接, 首先 选择承载网络列表最前面的承载网络尝试建立连接, 在连接建立成功后, 将所述 M2M应用请求发送给目标 CSE; 如果未能成功建立与目标 CSE的 连接, 则本地 CSE选择排在之后的承载网络(即排位第二的承载网络) 尝 试建立连接,并在连接建立成功后发送 M2M应用请求给目标 CSE,成功发 送 M2M应用请求后,本地 CSE发送请求发送成功的反馈给所述 M2M应用, 如果承载网络列表中的所有承载网络尝试建立连接都失败, 则反馈发送请 求发送失败的消息给所述 M2M应用;
如果本地 CSE读取的请求发送延迟时间的值不为 0, 本地 CSE则启动 定时器 Τ, Τ的值应该不大于请求发送延迟时间的值, 在定时器到时前, 本 地 CSE保存所述 Μ2Μ应用请求, 在定时器到时时, 尝试建立与目标 CSE 的连接, 连接建立方式同上文的描述, 在连接建立成功后, 将所述请求发 送给目标 CSE,并发送请求发送成功的反馈给所述 M2M应用,如果与目标 CSE连接建立失败, 则本地 CSE反馈请求发送失败的消息给所述 M2M应 用。

成功发送 M2M应用请求后, 本地 CSE发送请求发送成功的反馈给 M2M应用,如果与目标 CSE连接建立失败,则反馈请求发送失败的消息给 M2M应用。
综上, 本发明实施例在承载网络出现故障或断开时, M2M应用所发的 请求不会立即失效, 仍可以在本地 CSE保留一段时间, 当承载网恢复连接 或重新建立连接后, 本地 CSE可以将所述请求发送到目标 CSE。 另外, 本 发明实施例中, 将发送到同一个目标 CSE的请求进行组合, 在定时器到时 时同时发送到目标 CSE, 因此可以减少网络信令, 减少网络资源的消耗。
