摘要： A method, information processing system, and wireless communication system for optimizing neighbor lists. A set of target communication sectors (240, 242) are identified within a given distance threshold from at least one of the base station (106) and a wireless device (134) currently registered with the base station (106). At least one target communication sector (240) is randomly selected from the set of communication sectors (240, 242). An identifier associated with the at least one randomly selected target communication sector (240) is inserted into a base station neighbor list (138). The base station neighbor list (138) is prioritized based on a set of call detail records associated with the at least one randomly selected target communication sector (240).

摘要： A method (30) schedules the utilization of the supplemental channel of a base station transceiver (20-25). This scheduling includes time slot assignment as well as data transfer rate per time slot. One method simply selects the next time slot with a maximum rate for the primary base station transceiver (130). The method then selects the same time slot for each of the secondary links with the secondary base stations (132). The data is then simply sent to each of the BTSs (20-25) for transmission to the mobile station (10). In another alternative, a request is made for a supplemental channel usage for the primary link (144). Then secondary links are selected for transmission to the mobile station (10) only if they provide additional diversity gain (148) and resources are available at the secondary link BTSs.

摘要： A CDMA cellular communications network (400, FIG. 4) includes one or more aircraft (410), which relay pilot channel and control channel signals between base transceiver stations (BTS's 406, 413) and subscriber units (401). Over the control channel, the BTS transmits a handoff candidate list to the subscriber units. The handoff candidate list identifies candidate BTS's to which the subscriber unit, theoretically, could hand off. In addition, the list indicates at which offsets the subscriber units should search for short codes transmitted by the candidate BTS's over the pilot channel. Based on the path length between the BTS, aircraft, and subscriber unit, the candidate BTS's actually generate their short codes at an offset that is equal to or earlier than the offset reported to the subscriber unit by some delta. In addition, the BTS's can impose a variable delay on the generated short code bits to compensate for variations in the path delay as the aircraft flies in its flight pattern.

摘要： A mobile station typically determines whether to drop a communication link and/or a base transceiver station (BTS) based on a performance of an associated forward link. In order to avoid dropping a communication link that has a weak forward link but a strong reverse link, a communication system is provided that determines whether the reverse link is still good before determining to drop the communication link. In one embodiment, the communication system determines whether reverse link is still good based on a quality metric associated with the reverse link and quality metric(s) associated with one or more other reverse links that are in a soft-handoff mode with reverse link. In another embodiment, the communication system determines whether reverse link is still good by comparing a quality metric associated with the reverse link to a threshold.

摘要： A terrestrial cell site handoff list is dynamically maintained for an airborne cellular system. A beam pattern is maintained relative to an airborne cellular system repeater, but rotates relative to the geographic area of coverage. A location and heading of the airplane, locations of respective beams transmitted from the airplane based on airplane flight pattern data, and locations of respective cell sites within a vicinity of footprints of the respective beams transmitted from the airplane are determined. A list of viable handoff terrestrial cell site candidates is then calculated based on the beam pattern, the location and heading of the airplane, the locations of respective beams transmitted from the airplane based on airplane flight pattern data, and the locations of respective cell sites.

摘要： A method of locating a billing area associated with a cell phone call initiated in an airborne cellular communications system enables service providers to more accurately identify system user locations within the system's area of coverage. In operation, propagation delay and beam number location of an initiated call are identified to determine a current handset radial beam location. The propagation delay is then mapped to a stored closest corresponding radial geographic billing location, and the call is then associated with the closest corresponding radial geographic billing location. Additional system accuracy may be provided by determining azimuthal position within a beam footprint by determining a handoff location of a signal from a first beam to a second beam, and then mapping handoff information to a closest corresponding azimuthal geographic billing location. Both the closest corresponding radial and azimuthal geographic billing locations are then used to identify a current handset location. Such a system user location technique also enables an airborne system to comply with FCC E911 caller location requirements.

摘要： Network nodes (10, 15, 20, 25, 30 40) of a communication network (100) determine whether the queue position (56, 57) of a data packet (60) exceeds a threshold (55). Data packets which are placed in a queue that has a depth greater than the threshold, and therefore will experience increased delay at this node, are remarked to a higher priority for expedited handling at the next hop. The next hop network node which handles that data packet will put it in a higher priority queue (51) such that it will experience less delay at the that node. In this way, a negative correlation in node-to-node delay is achieved and overall delay variation is reduced.

摘要： The present invention corrects for Doppler shift in both forward and reverse links in a cellular communications system including an airborne repeater. A reverse link pilot reference signal in a band similar to a communications signal band is received at a reverse link processor, and the Doppler shift in the reverse feeder link is corrected based on the reverse link pilot reference signal. The Doppler shift in the forward feeder link is also corrected based on the reverse link pilot reference signal prior to the forward feeder link being affected by the Doppler shift. The present invention also compensates for signal strength variations due to changing flight pattern positions of the repeater. Pre-compensation for forward feeder link path losses due to movement of the airplane is performed to cause communications signals transmitted to and from the cellular communications system repeater to have identical strength before the signals are transmitted to the system user cell phones within the area of coverage.

摘要： A method and system for antenna pattern synthesis based on geographical distribution of subscribers allows more efficient use of satellite power resources in order to provide communications services to terrestrial-based subscribers (FIG. 1, 105, 115, 125, and 135). The method entails the grouping of terrestrial-based subscribers into communication beams (FIG. 5, 530) where gain is maximized (550) at the centroid of each beam. Additionally, gain in the directions of interfering emitters is minimized (540). A processor (FIG. 7, 740), which can be resident within a satellite (200), can perform the necessary processing to synthesize communication beams which service the terrestrial-based subscribers (105, 115, 125, and 135).
