摘要： A method for controlling a wireless communications system is provided. A plurality of substantially identical base stations, each capable of being operated as both a primary agent and a secondary agent are deployed. The secondary agent is capable of communicating with a mobile device and the primary agent is capable of communicating with a network. A network active set associated with a mobile device is formed from a plurality of the base stations. One of the base stations in the network active set is selected to operate as the primary agent, and it communicates to the other base stations that the selected base station is operating as the primary agent. Thus, communications between the network and the mobile device are routed through the primary agent and the selected secondary agent.

摘要： A method for locating a mobile device in a wireless communications system comprised of a plurality of base stations is provided. The method comprises associating the mobile device with a first base station of the plurality of base stations. Thereafter, a paging signal is delivered from a subset of base stations associated with the first base station to the mobile device. The subset of base stations may correspond to a network active set of base stations associated with the mobile device. Thereafter, when a signal from one of the base stations in the subset of base stations is received, indicating that the mobile device responded to the paging signal from the one base station, then the mobile device is located and may be associated with the one base station for future paging attempts.

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.

摘要： A method of scheduling and sub-channelization is provided for a wireless network such as an OFDMA network. Distributed coordination is applied across sectors, such neighboring sectors will tend to schedule cell-edge users at the same time, while sub-channelizing to different portions of the full frequency band available for forward link transmissions. This tendency is achieved by dividing each sector's users into user classes which depend upon forward link channel quality. Each user class is assigned a different set of priorities for use of available timeslots and subcarriers.
