  • Patent number: 7596373
    Abstract: Method and apparatus to monitor MQoS of wireless mobile devices is described. In one embodiment, the present invention provides a method to monitor the health of 3G mobile devices and provide a status check of such health to network technicians, supervisors, and management. In one aspect, mobile devices on the network perform measurement of MQoS factors that are reported to a quality of service backend. The MQoS data is combined to show current and historical network status. In another aspect, alarms may be set to notify specific managers when manager programmable conditions occur, such as low system performance, or specific error conditions occur. Reports may be generated summarizing and illustrating performance in tabular and graphical form. Parameters used for testing and monitoring mobile devices may be input to specific mobile devices or groups of mobile devices in a system.
