摘要： A remote unit (101) monitors a control channel for a base station (103) and sends a probe message (301) to the base station (103). The base station (103) forwards the probe message with location information (305) to a controller (115). The controller (115) determines an approximate distance for the remote unit (101). Based on the approximate distance, the controller (115) determines at least one additional site. A channel assignment message (309 or 401) is forwarded to the remote unit (101), which message includes one or more traffic channels associated with at least one of the base station (103) and the at least one additional site.

摘要： A method of automatically prioritizing cells in a neighbor list of a communications system. The priority is defined as the number of times a cell in the neighbor list has been added to the active set. Cells that have been added to the active set more often are given a higher priority. Such higher priority cells are considered first for addition to the monitored set because they are more likely to successfully move from the monitored set to the active set.

摘要： A method of protecting voice calls in danger of being dropped from a cell of a wireless communication system due to high speed data users. The method including the steps of calculating a signal-to-noise ratio based upon a forward link of each of the plurality of traffic channels within the cell and detecting when the cell is in a overload condition. The method further determines the gain associated with each traffic channels within the cell as well as the channels associated priority level. The method then reduces the gain on the traffic channels with the lowest priority to save the voice call from being disconnected.

摘要： A technique is used in a spread spectrum communication system (100) such as cdma2000 or UMTS to assign a subscriber unit (120) a link for a supplemental channel, during a handoff period. The technique includes queuing a data packet for transmission to the subscriber unit at a packet transmission time (221) determined by a queue delay (220), obtaining pilot signal strength measurements of at least two active downlinks (125) of the subscriber unit that are measured substantially at the packet transmission time, and determining a strongest one of the at least two active downlinks from the pilot signal strength measurements. The pilot signal strength measurements are obtained by determining a pilot signal measurement time (PSMT) for the subscriber unit, calculating a pilot signal measurement delay (PSMD) from the PSMT and the queue delay, and transmitting a pilot signal measurement request (PSMRQ) to the subscriber unit after the PSMD.
