摘要： Methods and systems are provided causing a mobile station to, after experiencing a dropped call, originate a subsequent call via a coverage area different than that used for the first call. In an embodiment, a mobile station detects that, when it was engaged in the first call at a first location via a first wireless coverage area, the mobile station experienced the first call being dropped. When the mobile station subsequently attempts to originate a second call, the mobile station determines that its current location is within a threshold distance of the first location, and responsively attempts to originate the second call via a second wireless coverage area different from the first.

摘要： Systems and methods for dynamically adjusting the size of an access search window are provided. In an embodiment a base station uses an access search window size, which is initially set to a default value, to determine whether to accept access requests from access terminals (ATs). The base station operates to accept access requests from ATs when the ATs are within the distance defined by the value of the access search window. The base station further operates to measure an amount of traffic for a sector of a wireless coverage area and change the value of the access search window size based on the amount of traffic on the sector.

摘要： Methods and systems are provided for using DRCLocks for conducting call admission control. In an embodiment, an access node provides service to a plurality of access terminals on a carrier in a coverage area, where the plurality of access terminals does not include a first access terminal. The access node receives a request for new service on the carrier in the coverage area from the first access terminal over an air interface, and responsively determines whether an aggregate-DRCLock condition is met. If the aggregate-DRCLock condition is met, the access node denies the request for new service.

摘要： Systems and methods for adjusting the power control settings in a wireless communication network are provided. In one embodiment, a base station determines a target access terminal's use of service so far in a billing period, wherein the target access terminal is located in a sector of the wireless communication network. The base station then determines whether the target access terminal's use of service is above a threshold value. Responsive to the base station determining that the target access terminal's use of service is above the threshold value, the base station adjusts a power control setting of one or more other access terminals located in the sector of the wireless communication network.

摘要： Methods and systems for adjusting the access search window based on the movement of a mobile station (MS) are disclosed. The MS searches for pilot signals using a search window that has an initial size. At a first and second time, the MS determines its position. The MS then determines the distance between the position of the MS at the first time and the second time. When the distance is less than a threshold distance, the MS measures the strength of a pilot signal within the access search window and identifies one or more signal peaks within the access search window that are above a specified signal strength. Next, the MS modifies the access search window into one or more smaller access search windows. The one or more smaller access search windows collectively have a size that is smaller than the initial size.

摘要： A radio access network (RAN) allocates a resource, such as a forward traffic channel, to a mobile station that is engaged in a call. During the call, the RAN monitors a reverse link signal that is received from the mobile station. If the RAN detects a reception failure, such as the receipt of an errored frame in the reverse link signal, the RAN determines the power level that the mobile station used to transmit the reverse link signal when the reception failure occurred. If the mobile station was already transmitting at its maximum power level, the RAN may immediately release the resource. Otherwise, the RAN defines a test period that is sufficient for the mobile station to increase its transmit power to the maximum level. If the reception failure continues throughout the test period, the RAN may then release the resource.

摘要： Methods and systems are provided for achieving quality of service (QoS) by using the reverse activity bit (RAB) in creation of neighbor lists for selected access terminals. In an embodiment, an access node provides service to a plurality of access terminals in a first wireless coverage area. The access node maintains and broadcasts a standard neighbor list identifying neighboring wireless coverage areas, each having a respective RAB. The access node generates a QoS neighbor list, consisting of one or more coverage areas from the standard neighbor list having a RAB that is cleared. The access node transmits the QoS neighbor list to a subset of the access terminals. Each access terminal in the subset uses the QoS neighbor list in place of the standard neighbor list, while the other access terminals use the standard neighbor list.
