Abstract: A wireless communication device (100) automatically and seamlessly switches to an alternate, available system when it is unable to complete a call origination attempt, without requiring the user to take any affirmative actions to select the alternate system or re-initiate a call origination. The wireless communication device (100) comprises a transceiver (104) and a processor (104). The transceiver (107) transmits and receives messages and signals. The processor (107) generates a first signaling message for transmission to a first communication system and generates a second signaling message for transmission to a second communication system if the transceiver does not receive an acknowledgement message from the first communication system. This decreases the percentage of call failures by providing a holdover of pending call origination attempts until service is finally acquired. In the case of either exceeding the maximum number of access sequences (reverse link limited) or failure to acquire the forward link of the preferred communication system (forward link limited), the user is not required to reinitiate the call origination, thus turning a potential call failure into a success.

Abstract: La utilizacion de recursos de un microprocesador por un proceso de busqueda es controlada determinando un tamano de ventana de busqueda, teniendo acceso a una tabla de consulta para determinar un intervalo de integracion y un numero de pases no coherentes, y ordenando un proceso de busqueda para ejecutar una busqueda de trayectoria multiple de acuerdo a esos parametros. La tabla de consulta comprende una pluralidad de intervalos de integracion y un numero correspondiente de pases no coherentes indexados de acuerdo a la ventana de busqueda, de modo que una duracion de ejecucion del proceso de busqueda permanezca nominalmente constante sobre una variedad de tamano de ventana de busqueda.

Abstract: Techniques to efficiently process paging channels in an asynchronous wireless communication system. In one aspect, if the base stations are not synchronized with each other and a remote terminal's designated page time is different from base station to base station, the remote terminal can wake up based on the earliest base station in a reacquisition search list that includes candidate base stations to which the remote terminal may be handed off. In another aspect, the criteria to select base stations for evaluation as reacquisition targets may be based on the received power of the base stations as well as their timing, both of which may be made relative to that of a preferred base station. In yet another aspect, the remote terminal may wake up multiple times in a particular paging cycle (i.e., a frame cycle or a DRX cycle) if there are one or more candidates base station to which the remote terminal may be handed off.

Abstract: Techniques to efficiently process paging channels in an asynchronous wireless communication system (100). In one aspect, if the base stations (104a, b, c) are not synchronized with each other and a remote terminal's (106) designated page time is different from base station to base station, the remote terminal (106) can wake up based on the earliest base station in a reacquisition search list (712) that includes candidate base stations to which the remote terminal may be handed off. In another aspect, the criteria to select base stations for evaluation as reacquisition targets may be based on the received power (512) of the base stations as well as their timing (514), both of which may be made relative to that of a preferred base station. In yet another aspect, the remote terminal may wake up multiple times in a particular paging cycle (i.e., a frame cycle or a DRX cycle) if there are one or more candidates base station to which the remote terminal may be handed off.

Abstract: One aspect of the invention provides a system, apparatus and method that allow a wireless communication device to intelligently search for and select a communication cell based on a system identifier (SID) and network identifier (NID) order of preference rather than just pilot signal strength. Generally, a mobile device scans a frequency channel associated with the highest preferred SID/NID for pilot signals at different PN offsets. The cell associated with the strongest pilot signal detected is queried to determine whether it belongs to the SID/NID sought. If the selected PN offset belongs to a cell associated with the SID/NID sought then it is used for communications. Otherwise, the SID/NID identification process is repeated for the next strongest PN offset detected on the same frequency channel. If no pilot signals meeting these criteria are found in the frequency channel, the next highest preferred SID/NID is selected and the process is repeated.
