摘要： A method of providing location information to a network application, a location server, a method of providing a trigger notification, a femto base station and a computer program product are disclosed. The method comprises the steps of: receiving details of a triggering event which is to be notified to the network application, the triggering event being a registration of user equipment with a predetermined femto cell of the wireless telecommunications network; providing triggering information indicative of the triggering event to that femto base station providing wireless communications coverage to the predetermined femto cell to cause that femto base station to provide a trigger notification indicating when the triggering event occurs; and in response to receipt of the trigger notification from the femto base station, providing location information to the network application, the location information providing the network application with an indication of the user equipment and the predetermined femto cell, together with an indication of when the triggering event occurred. This enables the movement of user equipment into specific locations to be detected and provided to network application efficiently, without any subsequent location determination processing having to occur, which provides a low-power, scalable, accurate and non-invasive approach requiring no modification of user equipment.

摘要： A method is provided of identifying which one of a plurality of femtocell base stations neighboring a first femtocell base station is to be the target for handover of a call connection with a user terminal from the first base station. The neighbor femtocell base stations use the same primary scrambling code as each other. The femtocell base stations use code-division multiple access, CDMA. Each of the neighbor femtocell base stations transmits a respective broadcast signal that include timing information such that each neighbor femtocell base station transmits a broadcast signal having different timing information to that of the other neighbor femtocell base stations. The user terminal receives broadcast signals, determines the timing information of at least one of the received broadcast signals and reports the timing information to the first femtocell base station. The first femtocell base station identifies the target femtocell base station for handover from the timing information.

摘要： A wireless communication system has at least one picocell within a macrocell. A method of communicating in that system includes using a set of predefined cell codes for respectively identifying macrocells. At least one predefined cell code is used for identifying all picocells within a macrocell to the macrocell. A picocell code distinct from the predefined cell codes is used for uniquely identifying a picocell to a mobile station with the macrocell. The mobile station is able to translate between the predefined cell code used by the macrocell to identify all picocells and the picocell code used to uniquely identify the picocell to the mobile station.

摘要： A method of decoding is provided comprising processing iterations. In each processing iteration, there is a first Max-Log-MAP decoding operation giving rise to a systematic error due to the Max-Log approximation, and a first weighting operation to weight extrinsic information from the first decoding operation to be applied as a priori information to the second Max-Log-MAP decoding operation. This is followed by a second Max-Log-MAP decoding operation, also giving rise to a systematic error due to the Max-Log approximation, and a second weighting operation to weight extrinsic information from the second decoding to be applied as a priori information to the first Max-Log-MAP decoding of the next iteration. The weights are applied to compensate for the systematic error due to the Max-Log approximation made in the last Max-Log-MAP decoding operation.

摘要： A radio telecommunications receiver operates to receive digital data symbols or bits by iterative determination of soft estimates of symbols or bits followed by a hard decision as to what symbol or bit was intended. The receiver comprises a first processor operative to provide first soft estimates of symbols or bits of the received signal and a second processor operative to decode the first soft estimates and to provide second soft estimates of the symbols or bits. The receiver also comprises a combiner operative to provide third soft estimates back to the first processor for subsequent further decoding, the third soft estimates of each symbol or bit being dependent upon the respective second soft estimate and a respective previous second soft estimate.
