摘要： For use in a wireless network, a controller for relay stations. The relay station increases cell coverage and user data rates while employing power consumption saving techniques. The relay station compares a threshold power setting with a current power setting. If the threshold power setting is greater than the current power setting, the relay station increments the threshold power setting and decreases the cell coverage. If the threshold power setting is less than or equal to the current power setting, the relay station decreases the threshold power setting until the threshold power setting is equal to a total power setting of the relay station. The relay station also employs load balancing techniques by comparing a threshold power setting with a current load setting. If the threshold power setting is greater than the current load setting, the relay station increases the cell coverage based on the available bandwidth.

摘要： For use in a wireless network, a base station that reduces the call set-up time for a time-sensitive application. The base station comprises a message controller for receiving an incoming control message that initiates the time-sensitive application in a mobile station. In lieu of a conventional page message, the message controller transmits a short data burst message to the mobile station to initiate the time-sensitive application. The short data burst message is transmitted in a forward control channel. The mobile station completes the set-up by transmitting back an L2 Acknowledgment message in lieu of a conventional page response message.

摘要： A base station for use in a 1xEV-DV/DO wireless network that communicates with mobile stations in its coverage area. The base station comprises a handoff controller for receiving a Handoff Request message from a first mobile station attempting to hand off to the base station. In response to receipt of the Handoff Request message, the handoff controller determines whether the available resources in the base station exceed a predetermined minimum threshold. If the available resources exceed the predetermined minimum threshold, the handoff controller allows the first mobile station to be handed off to the base station. Otherwise, the handoff controller prevents the first mobile station from being handed off to the base station.
