Abstract:
PROBLEM TO BE SOLVED: To save power by utilizing a non-CDMA communication path and to send emergency communication onto a CDMA communication path. SOLUTION: A portable communication device 100 also includes a controller 112 coupled to first transceiver circuitry 104 and second transceiver circuitry 116 for providing a deregistration message to the second transceiver circuitry 116 for transmission therefrom in response to determining that the portable communication device 100 is within signal coverage of the first communication path, activating the first transceiver circuitry 104 to send and receive signals on the first communication path, deactivating the second transceiver circuitry 116, and thereafter activating the second transceiver circuitry 116 at times separated by a predetermined time interval to monitor one or more housekeeping channels of the second communication path.

Abstract:
A method for controlling diversity receivers in a wireless communication device includes the steps of: determining if the wireless communication device is experiencing poor coverage (220), using a first receiver and a second receiver for diversity (230) if the wireless communication device is experiencing poor coverage, and using the second receiver for scanning (240) if the wireless communication device is not experiencing poor coverage. Thus, diversity can be used when needed to improve reception. Both receivers, however, can be used in a non-diversity mode to reduce current drain or to speed up channel acquisition when coverage is not poor.
Abstract:
A method in a terminal device ( 102 ) for acquiring a carrier system identified in an preferred roaming list (PRL) is disclosed. The method includes acquiring ( 202 ) a first carrier system from a first scan list, rearranging ( 204 ) the first scan list using a hashing algorithm to form a second scan list, removing ( 206 ) priority scanning for the first carrier system, and acquiring ( 208 ) a carrier system from the second scan list.
Abstract:
An apparatus (100) generates a preferred roaming list (108) for a wireless mobile station (404) that includes area identification data (such as GEO GROUP ID) (200) corresponding to an area serviced by at least one wireless wide area network, such as a ground based CDMA system and an area services by at least one in-vehicle wireless pico-cell (402), such as a wireless CDMA pico-cell located on an aircraft or any other suitable vehicle. The area identification data (200) is associated with a wireless in-vehicle pico-cell system identification data (205) and in the case of a CDMA pico cell system, a system identification data SID) and network identification (NID) data pair (206) associated with the in-vehicle wireless pico-cell (402).

Abstract:
A method and system for maintaining registration information for multiple communication areas within a network is provided. For a particular mobile subscriber, information associated with at least some prior registrations are retained, and in some instances are re-used upon re-entry into a communication area in which the mobile subscriber was previously located. The retention of registration information for multiple communication areas is managed as the default, without requiring additional signaling associated with each registration.
Abstract:
A method in a wireless communication device for silent redial comprising attempting to access a new system in response to a failed access attempt with a first system. The method includes determining (124) that the new system is not in the same GEO group as the first system. Receiving (126) the new system MCC/MNC and determining (130) that the new MCC/MNC is included on a home MCC/MNC list and then sending (132) an access probe sequence to the new system.

Abstract:
Disclosed are methods of synchronizing, by a mobile station, location information between a plurality of networks of different types. A method includes entering into the coverage area of a first access point of a first network by the mobile station, the first access point having associated location information including a first location value. The method also includes determining a second location value, in conjunction with a second network, and communicating location information between the first access point and the mobile station, including receiving the first location value from the first access point by the mobile station. The method further includes determining if the second location value is within a predetermined tolerance of the first location value. If the second location value is within the predetermined tolerance, the method also includes using the location information associated with the first access point for one or more emergency assistance services.
