    • Endpoint device, central data collection point, and associated methods for collecting data over a communication network between endpoints and the central collection point. Actual measurements from a sensor are obtained by the endpoint device at a relatively fine time granularity. The endpoint device generates reports for receipt by a central data collection point. The reports include regular reports containing a portion of the actual measurements representing sensor measurements at a relatively coarse time granularity, and exception reports, containing information representing one or more of the actual measurements that differ in frequency or granularity of regular report measurements. Each of the exception reports is generated in response to a determination that at least one of the actual measurements differs from a predicted value for that at least one of the one or more actual measurements by an amount that exceeds a pre-established limit.
    • 端点设备,中央数据收集点和用于通过端点和中央收集点之间的通信网络收集数据的相关方法。 来自传感器的实际测量由端点设备以相对精细的时间粒度获得。 端点设备生成中央数据收集点接收的报告。 这些报告包括定期报告,其中包含以相对较粗的时间粒度表示传感器测量的实际测量的一部分,以及异常报告,其中包含表示常规报告测量的频率或粒度不同的一个或多个实际测量值的信息。 响应于确定实际测量中的至少一个与所述一个或多个实际测量中的至少一个的预测值相差超过预先设定的限制的量的确定来生成每个异常报告。

    • A system and method for achieving least cost call routing (i.e., shortest terrestrial path between mobile terminal and a fixed terminal) for a mobile communications system by integrating a cellular satellite communications system with an existing GSM network to form an extended satellite GSM system and an enhanced satellite GSM system. The extended satellite GSM system incorporates the advantages facilitated by the GSM network with the extended coverage capability of the mobile satellites, and achieves least cost call routing by registering a mobile terminal with one designated gateway (i.e., home gateway). In accordance with another embodiment, the enhanced satellite GSM system achieves least cost call routing for all mobile terminal originated and terminated calls by minor modifications to the mobile terminal and home location register. The resulting arrangement has minimal impact on the GSM network system operation because the modification incorporates standard GSM procedures and protocols and implements data stored at the mobile terminal. Specifically, the resulting arrangement makes no modification to the operation of the mobile switching center or visitor location register (MSC/VLR) used within the GSM network.
    • 一种用于通过将蜂窝卫星通信系统与现有GSM网络集成以形成扩展卫星GSM系统和用于移动通信系统的移动通信系统实现最小成本呼叫路由(即,移动终端和固定终端之间的最短地面路径)的系统和方法, 增强卫星GSM系统。 扩展卫星GSM系统结合了GSM网络带来的优势,具有移动卫星的扩展覆盖能力,并通过向一个指定网关(即,家庭网关)注册移动终端来实现最低成本呼叫路由。 根据另一个实施例,增强型卫星GSM系统通过对移动终端和归属位置寄存器的微小修改来实现针对所有移动终端发起和终止的呼叫的最小成本呼叫路由。 所产生的布置对GSM网络系统操作具有最小的影响,因为修改包含标准的GSM程序和协议并实现存储在移动终端的数据。 具体地说,所得到的布置不会改变在GSM网络内使用的移动交换中心或访问者位置寄存器(MSC / VLR)的操作。
