摘要： A method and apparatus for selecting channel elements in a wireless communication system based on their performance history. Data is collected indicating the performance of various channel elements over time, preferably eliminating from consideration any performance degradation due to air interface (e.g., radio frequency) issues. The data is then used to sort the channel elements in a priority order, from best-performing to worst-performing. When a channel element is to be selected for use in connection with an air interface channel (e.g., traffic channel or control channel), the channel element is then selected in accordance with the priority order, such as by selecting the channel element that has performed best over time. The priority-based selection of channel elements can thus leave poor-performing channel elements for use as a last resort, which can be advantageous in times of heavy network loading for instance.

摘要： An access network may identify paging areas based on a reference location (e.g., a mobile station's last known location), where each paging area includes at least one coverage area. The access network may then determine paging-channel occupancies for coverage areas in at least identified paging area. In turn, the access network may adjust a given identified paging area based on the determined paging-channel occupancies, resulting in an adjusted paging area. For example, the access network may add coverage areas to the given identified paging area and/or remove coverage areas from the given identified paging area based on the paging-channel occupancies for those coverage areas. Thereafter, the access network may page a mobile station associated with the reference location in the adjusted paging area.

摘要： Disclosed herein is a method for improved paging in a wireless communication system. In a scenario where base stations broadcast congestion indicators to prevent mobile stations from registering in coverage areas that are experiencing threshold congestion, the method provides for a new form of zone based paging that accounts for the possibility that a mobile station has entered into a new zone but has not yet registered due to a threshold congestion state. According to the method, a paging attempt will be directed to the mobile station's zone of last registration and to only those coverage areas in at least one adjacent paging zone that are deemed to be experiencing threshold congestion.

摘要： A wireless communication system uses a series of repeating overhead time cycles that each comprise a plurality of time slots. The system exchanges overhead information with wireless communication devices during individual time slots. The communication system wirelessly receives a registration request for wireless communication service from a wireless communication device. The communication system processes loading information for the overhead time cycles or a quality of service level of the wireless communication device to assign the wireless communication device to one of the overhead time cycles. The communication system wirelessly indicates the assigned overhead time cycle to the wireless communication device. The communication device monitors the overhead time slots during the assigned one of the overhead time cycles and does not monitor the overhead time slots during the not assigned overhead time cycles.

摘要： Air interface protocols under the numerous wireless communication standards allow use of a quick-paging channel (QPCH) to expedite paging and call setup. When a hybrid mobile device is engaged in wireless communications under a first air interface protocol, it may periodically switch over to a second air interface protocol to check for pages on the slower standard paging channel (PCH). To increase throughput under the first air interface protocol, it would be useful to employ the QPCH under the second air interface protocol, to reduce time spent by hybrid device checking for pages under the second air interface protocol. However, the QPCH uses resources under the second air interface protocol, so it would be best to not have the QPCH activated at all times. According to the invention, the system would activate the QPCH under the second air interface protocol in response to there being more than an upper threshold number of hybrid devices active under the first air interface protocol. In turn, the system may deactivate the QPCH under the second air interface protocol in response to there being some lower threshold number of hybrid devices active under the first air interface protocol.

摘要： A mobile station receives a target pilot signal transmitted by a target transmitter in a spread spectrum communication system and measures its phase. The mobile station then defines a search window to search for the target pilot signal at a later time. The mobile station defines the center point of the search window based on the previously-measured phase and the mobile station's direction of motion and speed relative to the target transmitter. If the mobile station is moving toward the target transmitter, the center point is less than the previously-measured phase by an adjustment amount. If the mobile station is moving away from the target transmitter, the center point is greater than the previously-measured phase by an adjustment amount. The adjustment amount may depend on the mobile station's speed. After the search window is defined, the mobile station uses the search window to search for the target pilot signal.

摘要： A mobile station transmits a message by transmitting an access probe that includes the message preceded by a preamble. The mobile station selects the length of the preamble from among a first preamble length and a second preamble length. The second preamble length is greater than the first preamble length. The mobile station makes the selection based, at least in part, on the distance between the mobile station and the mobile station's primary base transceiver station (BTS). If the distance is greater than a threshold distance, the mobile station selects the second preamble length. If the distance is less than the threshold distance, the mobile station selects the first preamble length, provided that an idle handoff to a neighboring BTS that is more than the threshold distance away is unlikely.

摘要： A method and system is disclosed for selectively scheduling control channel messages ahead of traffic channel data. When a RAN in a wireless communication system operating at least according to IS-856 determines that a delay condition exists in the transmission of a particular control packet to access terminals, the RAN will determine if there is a particular traffic packet in active transmission that is classified according to best effort service (or similarly-characterized service class), and further if at least a threshold number of a nominal number of time-slot segments of the particular traffic packet remain untransmitted. If such a traffic packet is identified, the RAN will cancel transmission of the particular traffic packet and replace it with immediate transmission of the particular control packet.
