Method for controlling handoff between secondary agents in a wireless communications system

摘要

A method for controlling a communications session with a mobile device in a wireless communications system comprised of a plurality of base stations is provided. The method comprises selecting a plurality of base stations, where at least a portion of the base stations are adapted to operate as a secondary agent, and wherein the secondary agent is capable of communicating with a mobile device. Substantially similar control information regarding the communications session is maintained in a plurality of the secondary agents. A first one of the secondary agents is selected as a first serving secondary agent to communicate with the mobile device. The first serving secondary agent uses the control information during the communications session with the mobile device. In this manner, each of the secondary agents is capable of quickly and efficiently taking over the role of communicating with the mobile device.
