  • Patent number: 7747244
    Abstract: Several related methods and apparatus for re-establishing communication for a wireless communication device after a communication loss between the wireless device and a wireless communication network are disclosed. In one illustrative example, the wireless network broadcasts identifiers of wireless devices associated with communication losses in the wireless network over a control channel. After regaining signal coverage, a wireless device monitors the control channel to decode and compare each broadcasted identifier with an identifier of the wireless device. Based on a match between a broadcasted identifier and the identifier of the wireless device, the wireless device transmits a control message which informs the wireless network of the presence of the wireless device. Otherwise, the wireless device normally refrains from transmitting the control message to the wireless network.

  • 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.
