摘要： A method, system and program product which improves the QoS and GoS of voice and data traffic on an integrated communications network. An RF spectrum allocation application/algorithm provides initial allocation of a percentage of available spectral resources to current voice and data traffic. Each allocated percentage is bounded by a sliding window, which adjusts its location based on the changing need for the resources. Thus, a voice sliding window dynamically adjusts its location to provide additional spectral resources to voice traffic when the voice traffic increases and provides less spectral resources when the voice traffic decreases. Likewise, a data sliding window dynamically adjusts its location to provide additional spectral resources to data traffic when the data traffic increases and provides less spectral resources when the data traffic decreases. The size of each window is determined by input parameters. When heavy voice and/or data traffic is present, the maximum available spectral resources are utilized and shared between both traffic types based on the RF spectrum allocation algorithm. Whenever an overlap in the windows occurs, the algorithm dynamically determines which of the traffic types to allocate the remaining spectral resources based on a number of factors, including the cost/financial factors and QoS and GoS calculations.

摘要： A wireless communications system includes access networks and access terminals. Within each cell or cell sector, reverse links and forward links are defined between an access network and multiple access terminals in the cell or cell sector. Based on a reverse data rate threshold value calculated from noise measurements, the access network indicates to access terminals within its cell or cell sector whether activity on reverse links are to be increased or decreased.

摘要： A wireless communications network includes cell segments each having at least a first type wireless link and a second, different type wireless link. Network access equipment is able to hand off mobile stations between the first type and second type wireless links to balance the loading of the wireless links. In one example implementation, the first type wireless link is a 1×EV wireless link, and the second type wireless link is a 1×RTT or other CDMA 2000 wireless link. The carriers can be co-located within a common cell segment, or located within different cell segments.

摘要： An ANC is formed to “dummy fill” a neighbor list that is to be transmitted to a mobile terminal that is presently located in a border cell with neighboring BTSs for which a hand-off request cannot be granted. Accordingly, while a hand-off cannot occur to a BTS of a proximate cell that does not qualify as a neighbor because it is serviced by a different ANC in a 1xEVDO network, identifying the BTSs of the non-neighbor and proximate cells (“dummy list BTSs”) prompts the mobile terminal to request a hand-off to a dummy list BTS when the BTS provides a better pilot signal. Because the ANC can readily identify the BTS from the dummy list, it knows that a hand-off cannot be facilitated therefor. Accordingly, the ANC instructs the mobile terminal to drop the call (data packet connection). Because many wireless data packet networks utilize at least a subset of established IP protocols and are able to establish point-to-point protocol communication links (higher layer communication links), commanding a mobile terminal to drop the call is a command to drop the call at the lower layers. The point-to-point protocol communication link is then resumed and the effect of a hand-off is achieved.

摘要： A method of connection setup in mobile wireless data communications systems is disclosed where the connection setup time is decreased for delay-sensitive communications sessions relative to the normal connection setup time for confidence-dependent communications sessions. This is achieved by performing some of the connection set-up steps for delay-sensitive communications sessions after successfully demodulating a smaller number of indications identifying an access terminal's desired serving resource than would be demodulated in the case of a confidence-dependent communication session prior to performing the same connection set-up steps.

摘要： A method and system for connection management in a wireless data network, such as a 1xEV-DO network adds connections to new network sectors upon receipt of a connection request from an active terminal, but removes data connections that the active terminal requests to be dropped only after confirmation from the active terminal that a channel allocation message has been received and applied. The active network maintains an active set of connections that is at least as large as the active set maintained by the active terminal and does not initiate a connection termination if no confirmation of the channel allocation message is received. This allows for a reduction in the number of dropped connections.

摘要： A method and system provide a plurality of femto cells that are deployed within a macro cell of cellular network. The femto cells improve cellular service inside structures, such as residential and commercial structures. Femto base stations convert signals between an airlink-interface and core network to enable data communication between the mobile terminal and an access network to occur through the Internet and a public switched telephone network. The femto base stations are independent of each other and the macro cell. The method and system provide the femto base stations with interference awareness and mitigation techniques to minimize interference with the cellular network.
