Abstract: A method of signal transmission according to one embodiment includes requesting a packet data serving node to filter a specified traffic flow from among a stream of packets. The method also includes requesting a radio access network to provide an indicated quality-of-service (QoS) treatment for the flow over a wireless air interface. The method further includes rescinding the request to filter or the request to provide a QoS treatment in response to a failure of the other request.

Abstract: A wireless location system is disclosed that may be configured as a gateway for receiving a plurality of requests for locating mobile stations for, e.g., E911 requests, vehicle location or tracking. For each mobile station (MS) location request, the system: (a) activates one or more location estimators for locating the MS, (b) receives one or more MS location estimates from the estimators, and (c) transmits a resulting location estimate(s) to an identified destination. MS locations are determined using one or more locating technologies based on, e.g.: computed offsets from terrestrial base stations, satellite transmissions, indoor antennas, low range base stations, and/or signal fingerprinting. The system may: adapt with environmental changes, evaluate MS locations using heuristics/constraints, and/or adjust MS estimates for more reliable and accurate estimates. The system is useful for 911 emergencies, tracking, routing (e.g.

Each of the access points is pre-set with a plurality of water level values corresponding to an acceptable load thereof, and each of the water level values is pre-set with a corresponding trap up value. Only when the real-time load of one of the access points is up to the trap up value thereof, the access point actively sends a signal of a corresponding load status thereof to the NMS. Meanwhile, the NMS checks the water level values of the other access points belonged to the same group of the access point.

Abstract: An uplink signal-to-interference ratio for each of multiple mobile radio terminal connections supported in a cell in a cellular communications system is estimated. A signal-to-interference ratio error is determined for selected ones of the estimated uplink signal-to-interference ratios. One or more signal-to-interference ratio errors are identified that exceed a signal-to-interference ratio error threshold. An instability indicator associated with the cell is determined based on the one or more identified signal-to-interference ratio errors. A load control decision and/or a decision for scheduling one or more uplink mobile radio transmissions in the cell may then be made based on the instability indicator, e.g., to prevent a transmission power rush in the uplink in the cell and/or to efficiently use available resources for uplink transmissions.
