Method of positioning problem regions covered with indoor wireless network

ActiveUS20160337888A1Accuracy be guaranteeEasy to maintainGeometric CADNetwork topologiesCell IDCellular network
Method of positioning blind coverage regions in an indoor wireless network. The method comprises the following steps: constructing an indoor and outdoor combined three-dimensional spatial structural model of a target scene; recording and storing information of wireless access equipment which can be received by the target scene, both from the indoor wireless network and from an outdoor (e.g., cellular) network with overlapping coverage; establishing a wireless fingerprint database of the target building covering both the indoor and the outdoor wireless networks; when loss of coverage is detected, the UE handing over to the outdoor network to transmit a measurement report from which the outdoor network can derive the UE's position (e.g., through triangulation); deriving the UE's position in the indoor area by superimposing the obtained information on the fingerprinting database (by analyzing only those cell-Id's that appear on the MR) and interpolating the result (mean square error); if the obtained position is covered by the fingerprinting database (i.e., it is in the indoor area), determining that the position corresponds to a blind coverage area inside the indoor wireless area; otherwise, assuming that the UE has left the building and a normal handover has taken place.
