摘要： A Wireless Communication Device (WCD) includes multiple fingers that track one or more tracked transponder beams. Each tracked beam is from a respective tracked transponder. The WCD determines a tracked-beam searcher energy for each of the tracked beams, and an untracked-beam searcher energy for each of one or more untracked beams from each of the tracked transponders. The WCD attempts to determine a preferred one of the untracked beams that should become a tracked beam. This determination is made based on the tracked-beam and the untracked-beam searcher energies. The WCD assigns, or alternatively, reassigns, a finger to the preferred untracked beam when the attempt to determine a preferred untracked beam is successful. The transponders may be satellites or base stations.

摘要： A Wireless Communication Device (WCD) inter-operates with a Code Division Multiple Access (CDMA) communication system. The WCD operates in an idle mode wherein the WCD transitions between a sleep state to conserve power and an awake state to receive one or more paging signals. The WCD attempts to reacquire a first pilot signal associated with a first paging signal that was previously being demodulated, and a second pilot signal that was previously being tracked. The WCD performs a handoff from the first paging signal to a second paging signal associated with the second pilot signal when the attempt to reacquire the first pilot signal fails and the attempt to reacquire the second pilot signal is successful.

摘要： A wireless remote unit performs SPS acquisition interleaved with receiving paging information over a wireless slotted paging channel and receiving data packets over a wireless data communication system. The remote unit tunes to a pilot channel, synchronizes to an internal clock of the wireless remote unit with a pilot signal transmitted over the pilot channel; and starts a search for SPS satellites after completing synchronization with the internal clock.

摘要： 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.
