Abstract: A method of setting the appropriate hysteresis for cells in a wireless telecommunication network in order to reduce the rate of oscillating handoffs arising from a routine mobile station handoff from an originating cell to a neighboring cell. The method includes measuring the received signal strength in the originating cell and the received signal strength of at least one neighboring cell. The hysteresis is calculated by applying a statistical operation, such as the standard deviation, to at least one of the received signal strengths. Alternatively, the hysteresis calculation may include the handoff oscillation rate. The calculated hysteresis value may be presented to the operator for manual adjustment or may be input into self-configuring cells for the dynamic adjustment of hysteresis levels to improve the network operating performance.

Abstract: Interference and bit error rate measurements are made on the uplink and downlink to determine communications quality. Mobile station mobile assisted hand-off (MAHO) functionality is utilized to make the downlink measurements. Following filtering, the measurements are evaluated to identify potential candidates for reallocation. In one type of evaluation, when measured downlink bit error rate on a selected frequency is lower than a threshold and is worse than measured uplink bit error rate, then a better quality candidate is chosen to replace the selected frequency. In another type of evaluation, when a best available candidate has better interference than a worst quality one of the selected frequencies, that best candidate is chosen to replace the selected frequency.

Abstract: A radiocommunication method and system employs base station transmit power level setting based upon uplink and downlink pathloss. Measurements made by both the mobile station and the base station are used to improve the pathloss estimate, which in turn provides for a more appropriate power level setting for the base station.

Abstract: In a telecommunications network, a method and apparatus for allocating channels makes signal quality measurements for channels that are in use or available for use and for channels that may become available for use. Already selected channels (i.e., channels in use or available for use) that exhibit poor signal quality characteristics are exchanged with candidate channels (i.e., channels that may become available for use) that exhibit better signal quality characteristics to thereby improve the overall signal quality of the network.
