Abstract: A method of optimizing use of a plurality of high-rate packet data (HRPD) resources may include assigning one of the plurality of HRPD resources to each of a plurality of mobile stations that is coupled to a radio access network, where the one of the plurality of HRPD resources is used to establish one of a plurality of HRPD sessions between one of the plurality of mobile stations and a radio access network, and where each of the plurality of mobile stations is not using packet-switched data channel. Subsequently an additional mobile station wirelessly coupling to the radio access network and requesting an HRPD resource. A first HRPD resource is reassigned to the additional mobile station without notifying the first mobile station, where the first HRPD resource is used to establish an additional HRPD session between the additional mobile station and the radio access network.

Abstract: This method (110) adaptively sends control messages and a predetermined number of fast repeats of the control messages on the traffic channel of a mobile communication system. For a control message which has already been lost (118), the system sends the control message again with a first number of fast repeats (130) if the traffic channel is operating at a full rate; and the system sends the control message with a second number of fast repeats if the traffic channel is operating at a subrate. The number of fast repeats is selectable. If the control message has not been previously sent and the traffic channel is operating at a subrate (124), the system will send the control message with a third number of fast repeats (128).

Abstract: An RF power fairness method (26) receives a request for supplemental channel resources (160). If sufficient supplemental channel resources (time slots and data rates) are not available, the original request is modified (166). If there is multiple call activity on the supplemental channel, RF power is calculated for each of the simultaneous calls on the shared channel (202, 208). If successful time slots and data rates are found, a grant message is returned from the time slot manager (26) to the base station (164, 170, 180). If insufficient time slots and data rate power are determined, a deny request message is transmitted to the base station (184).

Abstract: 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).

Abstract: A method of power control in a 3G wireless communication system (100) incorporating fast forward power control, may include setting an initial base station transmit power boundary (402) and an initial signal-to-noise ratio boundary (502). A mobile station (102) may send a forward link FER measurement to a base station (106). The base station may perform at least one of a base station transmit power boundary adjustment (403) and a mobile station signal-to-noise ratio boundary adjustment (503) based on the forward link FER measurement received from the mobile station, thereby imposing dynamic constraints on the fast forward power control operation.

Abstract: 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.

Further, the network unit at least one of selectively fast repeating the control message and selectively increasing the power gain for the control message based on the handoff state transition and the set of signal conditions.

Abstract: 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.

Abstract: A method for adaptive power control in a mobile communication system (100) determines (120) whether an RF loading factor (110) is greater than a threshold value. If the RF loading factor is above the threshold value, the method reduces call quality (140). Next, a determination is made whether the RF loading factor is below a second threshold value (150). If the RF loading factor is below the second threshold value, the call quality of the mobile communication system is increased (160).

Abstract: When performing a soft-handoff, a communication system determines whether to engage in an analysis of a reverse link associated with a base station under consideration to be added to an active set of a mobile station (MS). Upon determining not to analyze the reverse link, the communication system adds the base station to the active set without evaluating the associated reverse link. Upon determining to engage in a reverse link analysis, the communication system evaluates the reverse link in order to assure that a communication link is not terminated, or dropped, as part of the soft-handoff until such time as the communication system may confirm that an acceptable quality reverse link is being added. The communication system then determines whether to add the base station to the active set based upon the evaluation.

Abstract: 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.
