Publication number: 20110134815Abstract: In one illustrative method, a method in a mobile station for use in reducing delays for data communications is described. The mobile station causes a request for packet data service to be sent to a wireless communication network. If the request for the packet data service is denied in response to the request, then the mobile station is set in a deregistered state. In addition, the mobile station initializes a timer with an initial value that is less than a periodic location update timer value which is broadcasted by the wireless communication network, and runs the timer. In response to an expiration of the timer, the mobile station causes another request for the packet data service to be sent to the wireless communication network.Type: ApplicationFiled: June 10, 2010Publication date: June 9, 2011Applicant: RESEARCH IN MOTION LIMITEDInventors: Jayasri Gunaratnam, Noushad Naqvi, Craig Ian Haight Swann, Hugh Hind, Bao Quoc Nguyen, Darcy Richard Phipps

Publication number: 20110021190Abstract: A network selection method for a mobile station which is associated with a Home Public Land Mobile Network (HPLMN) identified by a home Mobile Network Code (MNC) and Mobile Country Code (MCC) pair. The mobile station identifies a plurality of PLMNs in a geographic area, and selects a non-home PLMN identified by a non-home MNC/MCC pair and designated as a Registered PLMN (RPLMN). In response to regaining signal coverage from an out-of-coverage condition with the RPLMN, or being powered-on from a power-off state entered while operating with the RPLMN, the mobile station selects the HPLMN if the HPLMN identified by the home MNC/MCC pair is available. Otherwise, if the HPLMN is unavailable and the RPLMN identified by the non-home MNC/MCC pair is available, the mobile station selects the RPLMN. However, if the RPLMN is unavailable, the mobile station selects an alternate PLMN in accordance with an automatic or manual network selection method.Type: ApplicationFiled: October 4, 2010Publication date: January 27, 2011Applicant: RESEARCH IN MOTION LIMITEDInventors: Jayasri Gunaratnam, Noushad S.

Patent number: 7818024Abstract: In one illustrative example involving automatic network selection, a mobile station selects and operates with a non-home communication network. The mobile station then experiences an out-of-coverage condition with the non-home network (or a power down condition) but subsequently regains signal coverage (or is powered back on) in response, the mobile station scans to identify a plurality of communication networks in its coverage area. If a home network is identified as being available, the mobile station selects and operates with the home network. Otherwise, if the previous non-home network (e.g. the RPLMN) is identified as being available, the mobile station continues operation with the previous non-home network.Type: GrantFiled: February 27, 2004Date of Patent: October 19, 2010Assignee: Research In Motion LimitedInventors: Jayasri Gunaratnam, Noushad Naqvi, Bryan Taylor, Craig Ian Haight Swann, Darcy Richard Phipps, Hugh Hind, Bao Quoc Nguyen

Patent number: 7747266Abstract: 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.Type: GrantFiled: May 23, 2008Date of Patent: June 29, 2010Assignee: Research In Motion LimitedInventors: Jayasri Gunaratnam, Noushad Naqvi, Bryan Taylor, Craig Ian Haight Swann, Hugh Hind, Bao Quoc Nguyen, Darcy Richard Phipps
