所述 M2M机器终端包含机器硬件和通信模组。对于移动网络, 所述通 信模组用于实现 M2M机器终端接入通信网络并进行通信;所述机器硬件用 于实现 M2M业务。 M2M机器终端可以分为二种类型, 包括: M2M终端设 备和 M2M终端网关设备,所述 M2M终端网关设备下面可以接入延伸网络, 例如: 传感器网络、 工业控制网络、 广播电视网络或卫星通信网络等一切 信息交互网络。 本发明在后续的描述中将 M2M 终端设备简称为终端; 将 M2M终端网关设备简称为终端网关。
所述通信网络用于将 M2M业务数据在终端之间, 以及终端和 M2M业 务平台之间进行传输, 可包括广域网、 局域网、 或无线个域网等。
所述 M2M平台是实现 M2M业务逻辑的构成部件, 在网络分层架构图 中,向下实现对终端的管理;向上为 M2M应用提供应用程序编程接口(API ) 开放的功能;此外 , M2M平台还用于执行业务逻辑处理。 M2M平台是 M2M 产业链中的重要一环, 运营商通过控制 M2M平台实现对 M2M业务的主导 权。 M2M应用通过调用 M2M平台提供的 API, 开发并提供相应行业的应 用。
所述 M2M应用按照业务的发起方可分为二类业务, 分别为: 终端侧发 起的业务和网络侧发起的业务。
所述终端侧发起的业务一般为业务数据上报和告警信息上报等, 其承 载方式有二种,分别为基于 CS进行交互的业务和基于 PS进行交互的业务。 终端主动发起业务之前, 终端可能处于消息模式, 即: 终端短消息在线, 但数据连接不存在, 或终端也可能保持或存在数据连接, 或者上述两种情 况并存。 如果终端处于消息模式, 且需要在 PS上进行业务, 那么终端需首 先建立数据连接通道后才可进行业务。
所述网络侧发起的业务与终端侧发起的业务有相似之处, 即也可以通 过消息方式或数据连接方式进行业务交互, 对于通过消息方式进行的业务, 通常通过消息网关,例如:短信网关,彩信网关、无线应用通讯协议( WAP ) 网关、 非结构化补充数据业务(USSD ) 网关或行业网关等网络实体下发消 息; 对于通过数据连接方式进行的业务, 网络侧可利用可能已存在的数据 连接通道直接发起业务, 但对于没有数据连接通道的情况, 则首先需要通 过消息方式激活终端, 然后由终端主动建立起数据连接, 之后方可执行相 应业务。
目前, 对于网络侧发起的业务存在一定问题: 无论此时釆用消息方式 还是数据连接方式进行业务,如果网络侧的 M2M业务平台不清楚终端的状 态或者状态的变更, 即事件, 则可能导致无法下发业务。 例如: 如果终端 电力耗尽、 负荷过高、 或当前信号较弱时, 终端则可能无法进行正常工作, 且此时网络侧不能及时了解终端的状态或事件, 最终导致业务无法成功进 行;或者, 当 M2M终端或者终端网关同时支持多种通信模式时,如果 M2M 业务平台不能及时了解终端的状态或事件, 则无法进行不同通信模式的选 择。 发明内容
有鉴于此,本发明的主要目的在于提供一种 M2M业务中终端状态或事 件管理的方法及系统, 使得网络侧能获得终端的状态或事件, 并根据终端 的状态或事件进行业务判断和处理, 进而可以提高业务的效率。
为达到上述目的, 本发明的技术方案是这样实现的: 本发明提供了一种 M2M业务中终端状态或事件管理的方法,该方法包 括:

其中, 所述状态或事件管理单元设置于 M2M业务平台中、或者独立设 置; 相应的,
所述状态或事件管理单元独立设置时, 状态或事件管理单元还为 M2M 业务平台提供增加、 查询、 修改和删除状态或事件信息的功能。
其中, 所述终端或终端网关将状态或事件信息传输给状态或事件管理 单元, 具体为:

下面结合附图及具体实施例对本发明作进一步详细说明。
图 1 为本发明 M2M业务中终端状态或事件管理的方法实现流程示意 图, 如图 1所示, 该流程的实现步骤如下:
步骤 101 : 在原有 M2M通信系统中设置状态或事件管理单元; 其中, 所述状态或事件管理单元可设置于 M2M业务平台中、或者独立 设置, 如果独立设置, 则同时设置与 M2M业务平台进行通信的接口, 用于 状态或事件管理单元接收并存储终端或终端网关经网关设备和 M2M 业务 平台上报的状态或事件信息, 进而在后续操作中能够将状态或事件信息提 供给 M2M业务平台查询。
这里, 所述状态或事件管理单元独立设置时, 为支持上述功能, 需提 供相应的接口功能与 M2M业务平台进行状态或事件信息相关的业务交互 , 例如: 增加、 查询、 修改或删除状态或事件信息等操作。
步骤 102: 业务运行过程中, 终端或终端网关将自身状态或事件信息经 网关设备、 或经网关设备和 M2M 业务平台传递给状态或事件管理单元存 储;
具体为: 业务运行过程中, 如: 终端或终端网关上电、 终端或终端网 关登陆, 或者终端或终端网关状态或事件变更时, 终端或终端网关主动将 自身状态或事件信息上报给网关设备, 经网关设备传输给状态或事件管理 单元存储、 或者经由网关设备先将终端或终端网关的状态或事件信息传输 给 M2M业务平台, 进而传输给状态或事件管理单元, 由状态或事件管理单 元存储和管理。
这里, 由于网关设备包括多种不同的种类, 相应的, 所述终端或终端 网关传输状态或事件信息的方式可为: 短信、 彩信、 USSD、 WAP和 IP等。
进一步地, 业务运行过程中, 终端或终端网关也可在收到 M2M业务平 台或状态或事件管理单元所发的状态或事件信息请求时, 将自身的状态或 事件信息经网关设备发送给 M2M业务平台; 或者经网关设备、或经网关设 备和 M2M业务平台传输给状态或事件管理单元。
其中, 所述状态或事件管理单元所管理的终端或终端网关状态或事件 信息与所述终端或终端网关的标识对应 ,以便 M2M业务平台可通过终端或 终端网关的标识, 查找对应终端或终端网关的状态或事件信息。
在业务进行中, 如果网关设备发现终端或终端网关状态或事件异常时, 网关设备则向 M2M业务平台上 4艮状态或事件信息, 进而由 M2M业务平台 将终端或终端网关的状态或事件信息传输给状态或事件管理单元; 或者网 关设备直接将终端或终端网关的状态或事件信息传输给状态或事件管理单 元。
这里, 所述终端或终端网关上报的状态或事件信息可分为: 可达、 不 可达、 信号情况、 异常情况、 通信模式和负荷情况等。 当终端或终端网关 刚启动后, 即终端或终端网关上电后或要进行登陆时, 终端或终端网关主 动将自身的状态或事件信息上报给网关设备, 经由网关设备、 或经网关设 备和 M2M业务平台传输到状态或事件管理单元; 业务进行中, 当终端或终 端网关检测到自身状态或事件发生变化时, 则主动将变化后的状态或事件 信息通过网关设备、或经网关设备和 M2M业务平台传输到状态或事件管理 单元。 此外, 如果终端或终端网关的状态或事件信息发生变化, 那么终端或 终端网关也会将其状态或事件信息经网关设备、或经网关设备和 M2M业务 平台传输到状态或事件管理单元。
步骤 103: M2M业务平台向终端或终端网关下发业务前, 查询并判断 状态或事件管理单元中对应终端或终端网关的状态或事件信息, 并根据查 询所得的状态或事件信息执行对应的业务交互操作;
具体为: M2M业务平台主动向终端或者终端网关发起业务交互前, 查 询并判断状态或事件管理单元中对应终端或终端网关的状态或事件信息, 然后基于查询所得的状态或事件信息执行对应的业务交互操作。 例如: 如 果终端为 CS在线, 则通过短消息、 USSD或多媒体短信服务 ( MMS )等方 式进行交互; 如果终端为 PS在线, 则通过 IP方式进行交互。
下面结合几个具体实施例对本发明终端状态或事件管理的方法进行详 细描述。
