Abstract: A wireless node location mechanism that employs a differential signal strength metric to reduce the errors caused by variations in wireless node transmit power, errors in signal strength detection, and/or direction-dependent path loss. As opposed to using the absolute signal strength or power of an RF signal transmitted by a wireless node, implementations of the location mechanism compare the differences between signal strength values detected at various pairs of radio receivers to corresponding differences characterized in a model of the RF environment. One implementation searches for the locations in the model between each pair of radio receivers where their signal strength is different by an observed amount.

The method derives an approximation of the shape-defining parameters for the second reporting format such as to minimize a criterion function including the predefined target confidence value and determining the deviation of the confidence value for the approximated shape from the target confidence value.

Abstract: A system and a method for providing a mobility event triggered service of a target set and the target set are provided. When a mobility triggered service is started, a target set stores a unique identifier related to an area where the target set itself is currently located, and compares a unique identifier stored at present while identifiers are continuously stored during an agreed time interval in the mobility triggered service with the unique identifier related to the area where the target set itself is currently located. If there is the difference between two unique identifiers, the target set stores the unique identifier related to the area where the target set itself is currently located, and with determination of its movement, determines that an event of the mobility triggered service happens. Then, the target set reports the occurrence of the event to an H-SLP, and the H-SLP begins to calculate position values of the target set according to a set condition of a current mobility triggered service.

Abstract: The present invention relates to Assisted Global Positioning System (AGPS) high accuracy positioning in unknown cell areas. By using an approach of three alternative steps a reference position, needed for AGPS positioning, is determined. The first step involves using the location of any neighboring cell. The second involves using the location of a cell within the same Location Area as the cell serving the portable communication device to position. The third step comprises determining a fixed point within the same geographical area as the Serving Mobile Location Center (SMLC) is serving, and using this fixed point as a reference location. Using the three-step approach the AGPS positioning can be optimized, providing a possibility to position, for instance a mobile phone, by AGPS even though the location of the cell serving the phone is unknown to the positioning node operating the serving cell.

But, if the WCD is moving at a speed above the given velocity, the RAN may use more wireless coverage areas when communicating with the WCD.
