Abstract: A femto cell is located within a macro cell of a wireless communication system. A method of identifying the femto cell comprises: determining at least one timing difference, the at least one timing difference being observed for communications between a wireless communication unit and each of a femto cell and at least one macro cell; and comparing the at least one observed timing difference to reference timing difference data. The identity of the femto cell may allow the location of the femto cell to be set as a geographical location for a wireless communication device that is within the footprint of the femto cell. The identity of the femto cell may allow hand in of an ongoing call, from the macro cell to the femto cell.

Abstract: A data management system and method of managing call data for at least one radio network element within a cellular communication network. The method comprises receiving geolocation associated call data for at least one call within the at least one cellular communication network, arranging the received geolocation associated call data for the call into at least one call data record, and writing the at least one call data record to at least one data storage device, The geolocation associated call data for the at least one call comprises at least two spatial coordinate values for an at least two dimensional spatial reference, and the method comprises indexing the at least one call data record within the at least one data storage device using a single dimensional coordinate value.
