20110319100 | ASYNCHRONOUS WIRELESS COMMUNICATION SYSTEM - The invention relates to an asynchronous wireless communication system, such as a UMTS system. The various base stations of an asynchronous wireless communication system do not typically have known timing offsets Tb(i), and these timing offsets vary with time. The invention allows the calculation of the difference dTb(i,j) between timing offsets Tb(i), Tb(j) for pairs of base stations B(i), B(j), using the timing of signals received by one or more wireless communication units. Having eliminated the timing offsets between the base stations as a variable, geo-location techniques from synchronous networks may then be used to locate wireless communication units in the asynchronous wireless communication system. | 12-29-2011 |

20130005326 | METHOD AND APPARATUS FOR DETERMINING THE IDENTITY OF A FEMTO CELL - 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. | 01-03-2013 |
20130005327 | METHOD AND APPARATUS FOR DERIVING FEMTO CELL TIMING INFORMATION - A method for deriving timing information for a femto cell of a wireless communication system comprises a wireless communication unit of the system receiving observed timing data for a femto cell within a macro cell, and observed timing data for the macro cell. Timing difference values between timing offsets for the femto cell and timing offsets for the macro cell are used to determine a central reference timing difference value for the femto cell. The central reference timing difference value is set as reference timing information for the femto cell. A network element and computer program product for implementing the method of the invention are also provided. | 01-03-2013 |
