    摘要: A method and system for dynamically controlling the transmission of reverse-link control signals to help reduce interference on the reverse link. A RAN identifies a mobile device whose transmission of reverse-link control signals best represents the reverse-link air interface condition of each other mobile device in a plurality of mobile devices. Then the RAN causes each mobile device in the plurality other than the identified mobile device to not send its respective reverse-link control signal at a given time, thereby reducing the number of mobile devices that transmit reverse-link control signals at the given time.

    摘要: A method and system for managing broadcast of notifications indicating whether system information has changed, so as to enable served devices to determine when to read and store updated system information. A radio access network tracks changes in system information on a per wakeup cycle basis, so as to determine whether system information has changed since a last instance of broadcasting such a notification in a particular wakeup cycle. If system information has changed, the network responsively broadcasts an indication that system information has changed, so as to cause devices operating on that wakeup cycle to read and store the updated system information. Whereas, if system information has not changed, the network responsively broadcasts an indication that system information has not changed (or forgoes broadcasting an indication that system information has changed), so that devices operating on that wakeup cycle can avoid reading and storing the system information.

    摘要: A method and system for dynamically adjusting reverse-link ACK transmission power based on forward-link timeslot utilization. A radio access network (e.g., a base station) may monitor timeslot utilization on the forward link and, upon detecting that the timeslot utilization is threshold high, may cause one or more served access terminals to increase their ACK transmission power, thereby possibly helping to minimize re-transmissions for data packets that have already been successfully received, and thus helping to minimize unnecessary use of potentially scarce forward-link timeslots.

    摘要: Disclosed herein are methods and systems for managing usage of traffic-channel resources in an access network, which are preferably resources that are reserved during a traffic channel assignment (TCA) process. An exemplary method comprises (i) a base station determining a usage level of at least one traffic-channel resource in a coverage area of the access network; (ii) based at least in part on the determined usage level, updating one or more TCA parameters affecting expected usage of the traffic-channel resource resulting from the TCA process; and (iii) performing the TCA process according to the updated TCA parameters. Preferably the usage level is determined for Medium Access Control Identifiers (MAC_IDs). Further, the access-channel occupancy (ACO) may be determined and the base station may further base the updating of TCA parameters on the ACO. In an exemplary embodiment, the updated TCA parameters include the TCA count and/or the TCC wait timer.

    摘要: Methods and systems are disclosed that may help a base station to adjust forward-link data rates in a given sector based on transmission-power variations in neighboring sectors. An exemplary method involves a base station that serves a first sector: (a) determining a respective transmission power for each of two or more channels of a second sector, (b) detecting a transmission-power difference between at least two of the channels of the second sector, and (c) in response to detecting the transmission-power difference: (i) determining a data rate control (DRC) adjustment for the first sector based at least in part on the transmission-power difference; and using the determined DRC adjustment to determine a forward-link data rate for at least one access terminal in the first sector.

    摘要: A mobile station involved in a call receives a forward link signal from a radio access network (RAN) and transmits a reverse link signal to the RAN. If the mobile station detects a reception failure of the forward link signal, such as the receipt of an errored frame, the mobile station transmits a wait time to the RAN. The wait time specifies how long the reception failure can continue before the mobile station will discontinue transmitting the reverse link signal. In response, the RAN may increase the transmit power level at which the RAN transmits the forward link signal, such that a maximum transmit power level is reached during the wait time. The wait time could be based on a user preference and/or user behavior with respect to abandoning calls.

    摘要: In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign resources, such as transmit power or frequencies, to wireless coverage areas serving particular altitude ranges in a proportion that is commensurate with the number of WCDs being served by these particular altitude ranges. As a result, RAN and WCD performance may improve.

    摘要: In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign an initial transmit power to a particular WCD based on the particular WCD's altitude. For instance, if the particular WCD is above a threshold altitude, the RAN may set the initial transmit power to the WCD to a lower value. However, if the WCD is below the threshold altitude, the RAN may set the initial transmit power to the WCD to a higher value, to overcome low-altitude signal obstructions. As a result, RAN and WCD performance may improve.
