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.

摘要： PROBLEM TO BE SOLVED: To provide a device to facilitate efficient use with a low frequency and low power for a sleep mode even when relatively large slot cycles are defined in a slotted paging system.SOLUTION: The technique includes reducing power in a wireless communication device for a first sleep period and then increasing power in the wireless communication device for an intermediate wake period after the first sleep period to estimate an error of a sleep clock. The method further includes reducing power in the wireless communication device for a second sleep period after the intermediate wake period. An intermediate wake mode implemented during the intermediate period can be used to estimate an error of a sleep mode without performing one or more tasks associated with an awake mode, such as demodulation.

摘要： PROBLEM TO BE SOLVED: To decrease the percentage of call failures in a wireless communication device by automatically switching to an alternate, available system for call origination when it is unable to complete a call origination attempt, without requiring the user to take any actions to select the alternate system or re-initiate a call origination.
SOLUTION: The wireless communication device includes a transceiver 104 and a processor 107. The processor 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.

SOLUTION: The wireless communication device comprises a transceiver 104 and a processor 107. The processor 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 affirmative acknowledgement message from the first communication system. This decreases the percentage of call failures by providing a hold-over 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 (forward link limited), the user is not required to re-initiate the call origination.

摘要： Microprocessor resource utilization by a searching process are controlled by determining a search window size, accessing a lookup table to determine an integration interval and a number of non-coherent passes, and commanding a searching process to execute a multipath search according to these parameters. The lookup table comprises a plurality of integration intervals and corresponding number of non-coherent passes indexed according to search window such that an execution duration of the search process remains nominally constant over a variety of search window sizes.

摘要： 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.

In one aspect, if the base stations (104a, b, c) are not synchronized with each other and a remote terminal's (106) designate d page time is different from base station to base station, the remote termina l (106) can wake up based on the earliest base station in a reacquisition sear ch list (712) that includes candidate base stations to which the remote termina l may be handed off. In another aspect, the criteria to select base stations f or 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 mad e 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 stati on to which the remote terminal may be handed off.

摘要： A wireless communication device which 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 decreases the percentage of call failures by providing a hold-over 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 re-initiate the call origination, thus turning a potential call failure into a success.
