Abstract: Teachings herein improve selection of the positioning method(s) used to obtain positioning information responsive to a positioning request, by approaching positioning QoS holistically. Approached holistically, a joint QoS metric as taught herein takes into account the joint effect of individual QoS parameters of a positioning method, or the joint effect of multiple methods in a sequence. Processing in one or more embodiments thus includes determining a joint QoS metric for each of a plurality of candidate positioning methods or sequences, and selecting a positioning method or sequence based on those joint QoS metrics. By selecting a positioning method or sequence in this way, holistically based on joint QoS metrics rather than a piecemeal approach based on a one-by-one check of individual QoS parameters, selection proceeds flexibly according to actual QoS requirements of position-based services and/or systematically according to the joint effect of multiple positioning methods.

Abstract: A method for power control stabilization in the uplink of a cellular CDMA communication system applying a fast inner loop power control comprises determining (210) of a radio frame based RoT value for a cell. A radio frame based SINR is determined (212) for individual UEs in the cell. The RoT value is compared (214) with a first threshold. Each frame based SINRs is compared (218) with a second threshold. The fast inner loop power control for a UE is broken (220) in dependence of the comparisons. The breaking comprises commanding (222) of a first number of consecutive power down commands to UEs having the frame based SINR above the second threshold for a RoT value above the first threshold and toggling (224) of power control commands for the subset of UEs during a second number of radio frames for a RoT value above the first threshold.

Abstract: A method and NodeB for assisting, in a first NodeB, in soft handover procedures in WCDMA time division schedules comprises estimating (210) of a high bandwidth neighbour cell interference power for each time division slot. A first change trend of the estimated high bandwidth neighbour cell interference power is computed (212) for each of the time division slots. A future incoming soft handover event of a UE from a neighbour NodeB to the first NodeB, and a future incoming soft handover time for the future incoming soft handover event, is predicted (220). This prediction is based on the first change trend of the estimated high bandwidth neighbour cell interference power. Scheduling of time division slots of UEs is adapted (230) before the predicted future incoming soft handover time. This adaptation is configured to create interference power headroom for the predicted future incoming soft handover event.

Abstract: Presented are methods and apparatus for generating an inaccuracy characteristic for a fingerprinting positioning algorithm calculation associated with a user equipment location. Fingerprinting positioning measurements are compared to high-accuracy positioning measurements and an error value is determined. The error values are accumulated and the inaccuracy characteristic is generated based on an inaccuracy calculation. For areas where insufficient data is available, an inaccuracy characteristic value can be interpolated or extrapolated from adjacent areas containing sufficient data.

Abstract: Mobile broadband traffic has been exploding in wireless networks (300) resulting in an increase of interferences and reduced operator control. Networks (300) are also becoming more heterogeneous putting additional demand in interference management. There is currently no support for signalling of neighbor cell interference gleaned from soft and softer handover powers. Thus, there are no algorithms that accounts for and/or estimates interference impact factors between neighboring cells based on neighbor cell interference estimates gleaned from soft and softer handover power. To address these and other issues, techniques to accurately predict/estimate neighbor cell interferences that accurately accounts for own cell powers,soft handovers, softer handovers, neighbor cell interferences, and remaining neighbor cell interferences are presented. The described techniques estimate coupling effects of scheduling decisions in one cell to surrounding cells. In this way, interferences in the network (300) can be managed.
