具体应用实例一 管理平台定义故障或异常事件， 如下： 事件 A: 断开连接； 判定事件 A的相关参数： 最大检测周期： X秒； 管理平台将定义的事件及其参数发送到无线传感网网关。 无线传感网网关在检测周期内对连接到该无线传感网网关的无线传感网 络终端进行监控和检测。 无线传感网网关根据接收到的事件相关参数设置检 测周期 T, 其 T值等于或小于最大检测周期： X。 检测方法可以如下：
3.1、 设置一个定时器 Timerl , 定时长度为 T秒， 在每一个检测周期开 始时启动定时器 Timerl , 发送检测信息给无线传感网络终端， 无线传感网络 终端在接收到该检测信息后， 向无线传感网网关发送在线反馈消息， 该反馈 消息可以是一条从终端到网关的控制信令。 如果在检测周期结束时， 及定时 器 Timerl到时时，仍未收到该无线传感网络终端的在线反馈消息，则判定其 断开连接。
3.2、无线传感网网关为每个无线传感网络终端启动一个时长为检测时间 的定时器 Timer2, 定时长度为 T秒， 如果在定时器 Timer2到时时都没有接 收到来自于某个无线传感网络终端的任何信令或数据，则判定为其断开连接。 如果在定时器 Timer2到时前接收到该无线传感网络终端的信令或数据，则重 启定时器 Timer2。
3.3、 无线传感网网关将最大检测周期 X (单位秒）发送给无线传感网络
终端， 无线传感网络终端在本地设置一个定时器 Timer3 , 定时长度等于或小 于最大检测周期 X秒， 在定时器 Timer3到时后发送在线指示信息给无线传 感网网关， 并重启定时器 Timer3。 无线传感网网关本地也启动一个定时器 Timer4, 时长可以等于或小于最大检测周期， Timer4的时长不得小于 Timer3 的时长，如果定时器 Timer4到时时，没有接收到无线传感网络终端的在线指 示， 则判定为其断开连接。 当无线传感网络终端需要正常断开连接时， 发送离线指示给无线传感网 网关， 则无线传感网网关不再对该终端进行监控和检测。
4、一旦无线传感网网关检测到某个无线传感网络终端断开连接，则将该 故障或异常事件报告给管理平台。 报告内容包括： 发生的故障或异常事件： 事件 A, 无线传感网络终端标识： WSN— UE— ID, 或 /和故障或异常事件发生 的时间 :2010-5-27 13:53 , 或 /和故障或异常事件发生的地点: (Χ,Υ),其中 X, Υ 是终端的经纬度坐标， 或无线传感网关的 ID: WSN— GW— ID。
5、管理平台在接收到无线传感网网关发送的报告后，将该信息立刻通知 无线传感网络终端的使用用户。 通知方式可以是管理平台发送一条警报信息 给短消息管理中心， 由短消息管理中心将该警报信息发送给使用用户。
具体应用实例二： 管理平台定义故障或异常事件， 如下： 事件 B: 非法移动， 该事件应用于终端用户签约时固定了无线传感网络 终端的位置。 比如自动贩卖机监控设置， 停车场监控设备等。 判定事件 B的相关参数： 签约的位置信息， 该信息为一个位置范围， 用 经纬度坐标表示 （X1-X2, Y1-Y2 ) , 其中 XI小于 X2, Y1小于 Y2。 相应的处理方法： 拒绝终端接入， 或减少提供给该终端的资源， 或对该 终端执行去附着。
2、 管理平台将需要监控的事件， 以及相关的参数， 或 /和事件发生后的 处理方法发送给无线传感网网关。
3、无线传感网网关根据接收到的事件相关的参数对接入的无线传感网络 终端进行监控和检测， 其事件检测方法如下：
3.1、 如果每个无线传感网终端包含有全球定位系统（Global Positioning System, GPS ) 定位模块， 可以在请求接入时， 将位置信息作为请求信令的 一部分， 其中位置信息为该终端的经纬度坐标（X, Y )。 当无线传感网网关 接收到请求后， 判断接入请求中的位置信息（X, Υ )是否在事件相关参数定 义的范围之内，具体判断方法是比较终端的经度 X是否在事件相关参数中的 XI与 Χ2之间， 以及比较终端的纬度 Υ是否在事件相关参数的 Y1与 Υ2之 间， 如果 X的值小于 XI或者大于 Χ2, 或者 Υ的值小于 Y1或者大于 Υ2, 则认为终端的位置超出定义的范围， 判定该终端为非法移动。
3.2、 在无线传感网终端第一次请求接入时， 无线传感网网关保存其位置 信息（Xa, Ya )。 在该终端后续的接入中， 终端仍然需要将当时的位置信息
( Xb, Yb )包含在接入请求中， 无线传感网网关可以比较接入请求中的位置 信息 （Xb, Yb )和上一次接入的位置信息 （Xa, Ya )是否相符， 具体比较 方式为 Xb是否大于等于 Xa-m,并且小于等于 Xa+m, Yb是否大于等于 Ya-m, 并且小于等于 Ya+m, 这里 m是位置统计误差余量值， 表示在这个范围内的 位置偏差是可接受的， 并且管理平台或者用户服务器没有更新其位置信息， 则判定为非法移动。
4、一旦无线传感网网关检测到某个无线传感网络终端发生非法移动，则 将该故障或异常事件报告给管理平台， 报告内容包括： 发生的故障或异常事 件： 事件 B (非法移动） ， 无线传感网络终端标识： WSN— UE— ID, 或 /和故 障或异常事件发生的时间： 2010-5-27 10: 48, 或 /和故障或异常事件发生的 地点： 经纬度坐标或者无线传感网关标识 WSN— GW— ID; 或者当网关本地已 经接收到管理平台发送的该事件的相应的处理方法时， 则根据处理方法执行 操作， 即拒绝该终端的接入， 或减少提供给该终端的资源， 或对该终端执行 去附着。
5、管理平台在接收到无线传感网网关发送的报告后，可以将该事件的相 应的处理方法发送给无线传感网网关。
6、无线传感网网关根据接收到的该事件的相应的处理方法执行操作， 即 拒绝该终端的接入， 或减少提供给该终端的资源， 或对该终端执行去附着。
