  • Patent number: 7747266
    Abstract: In one illustrative method, a periodic location update timer value is broadcasted by a wireless communication network and received and stored in memory of a mobile station. A request for data service is transmitted by the mobile station to a wireless communication network, and the request is reattempted at least one time in response to identifying a rejection of the request. If the request for the data service is accepted in response to the request, the mobile station operates in the wireless communication network using the data service. On the other hand, if the request for the data service is not accepted, the mobile station is set in a data service deregistered state. A timer is initialized with an initial value that is less than the periodic location update timer value and started. In response to an expiration of the timer, the mobile station repeats the transmission of the request for the data service and any reattempts in response to any rejections of the request.

  • Publication number: 20100020697
    Abstract: A method and system for monitoring the health of a wireless telecommunication network. Network health is monitored without placing an administrative burden on the carrier network itself, instead, this burden is placed on components that lie outside the carrier network and pass communications through it. The data service provider infrastructure sends a request to a mobile device, asking that it return data regarding its location. The carrier networks handling the request insert location information into the packet that is sent to the mobile device, but this information is not sent to the data service provider infrastructure itself. The mobile device harvests this location information from the packets it receives and inserts it in a response packet that finds its way back to the data service provider infrastructure. The data service provider infrastructure is able to collate this location data and to analyze it, determining the carrier network's health.
