摘要： A mobile station that is being served by a current sector receives a neighbor list that identifies a plurality of neighboring sectors and a respective priority for each neighboring sector. For each neighboring sector, the mobile station scans for the sector's pilot signal at a respective scanning frequency during a measurement interval. The scanning frequency for a sector defines how frequently the mobile station scans for the sector's pilot signal during the measurement interval. The mobile station selects a scanning frequency for a neighboring sector based on at least a signal strength of the current sector and the neighboring sector's priority. When the current sector's signal strength is high, the mobile station scans for high-priority sectors more frequently than low-priority sectors. When the current sector's signal strength is low, the mobile station scans for low-priority sectors more frequently than high-priority sectors.

摘要： A first serving system controls a first group of sectors that transmit pilot signals having pseudonoise (PN) offsets corresponding to a first PN increment, and a second serving system controls a second group of sectors that transmit pilot signals having PN offsets corresponding to a second PN increment. The first serving system serves a mobile station via a sector in the first group and determines that the mobile station is likely to be in a communication range of at least one sector in the second group. In response, the first serving system instructs the mobile station to use the second PN increment when scanning for pilot signals. Thereafter, the mobile station may use the first PN increment to scan for pilot signals to add to its remaining set and, if the remaining set is not large enough, may then use the second PN increment to scan for additional pilot signals.

摘要： A method and system for using call drop and re-origination data to trigger handoff of wireless communication devices. Handoff trigger data is established in response to detecting that at least one mobile station experienced a call drop and then quickly re-originated on a sector that was not included in the mobile station's active set at the time of the call drop. The handoff trigger data correlates a location where the call drop occurred with the sector on which re-origination occurred. When another mobile station is thereafter engaged in a call at or near that location and does not have the sector in its active set, a serving radio access network may direct the mobile station to handoff to the sector, in an effort to prevent a call drop.

摘要： System and methods for generating and transmitting dynamic route-update-radius parameters are described. The parameters are dynamic in that the parameters may be modified from time-to-time. Modification of the parameters may be triggered by a radio access network (RAN) determining that a coverage area formed by the RAN is handling more than a threshold amount of communications to and/or from access terminals operating in the coverage area. The RAN may transmit the dynamic route-update-radius parameters so as to prevent some access terminals from registering with the coverage area while the coverage area is handling more than the threshold amount of communications. While the coverage area is handling a reduced amount of communications, such as less than a threshold amount of communications, the access network may transmit default route-update-radius parameters to coverage areas remote from that coverage area. The route-update-radius parameters may include a route-update-radius, a modified route-update-radius, and a route-update-radius offset.

摘要： Methods and computer-readable media are provided to determine which sector the mobile device will bias during soft handoff. Signals are received from multiple sectors, and for a first quantity of time slots of a frame, the signals are inspected to determine whether a quality threshold is met. Based on whether the quality threshold is met, each sector is assigned a power control command indicating that either a decrease or increase of output power is recommended when a subsequent signal is sent to the mobile device. For a second quantity of time slots, the overall power control command sent to the sectors corresponds to the power control command assigned to the sector that has communicated the highest quality signals for the first quantity of time slots of the frame.

摘要： Wireless access terminals operating in a radio access network (RAN) may move from one coverage area to another coverage area formed by base stations within the RAN. The RAN tracks the location of the access terminals so that RAN can efficiently route communications, such as page messages, to a base station serving the access terminals. From time-to-time, the access terminals can send route-update messages to inform the RAN of their locations. Sending the route-update messages can increase the loading on base station channels that carry the messages. Methods, systems, and devices for delaying transmission of the route-update messages are described. Delaying or not delaying transmission of the route-update messages may be dependent on occupancy of access channels of a base station and whether the access terminals are mobile at the time the route-update messages are to be sent.

摘要： Systems, computer-readable storage media, and methods are disclosed for providing wireless voice communication transmissions between a mobile unit and at least one base station. An illustrative method may comprise receiving an access request from a mobile unit. Based on information extracted form the access request and protocols for selecting a communication channel, identifying a selected communication channel for transmissions between the mobile unit and the base station. In the event of congestion or poor RF quality on the selected communication channel, where multiple communication channels associated with a home network are available at a base station, the mobile unit will attempt to access an alternate communication channel before going to a roaming network.

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： Methods and systems for adaptive hybrid automatic repeat request (H-ARQ) protocols are disclosed. The protocols preferably adapt to changing network conditions between a client node and an access node by omitting the transmission of certain messages when network conditions are determined to be favorable. In doing so, packets are processed faster, thus reducing communication latency as well as the memory requirements of the protocols. One scenario in which the protocols may operate is where the client node is a wireless communication device coupled to the access node via a wireless network. In such a scenario, the access node may, from time to time, measure a quality of the wireless air interface between the client node and the access node, and determine whether to transmit an acknowledgement message based on the outcome of the measurement as compared to a threshold value.
