摘要： A method in a communication device for providing a location information of the communication device to a Minimization of Driving Tests, MDT, server is disclosed. The communication device operates in a wireless communication environment which comprises multiple networks comprising at least one cellular network and at least one satellite positioning system. The communication device starts an MDT measurement and determines a signal strength received from a satellite in the satellite positioning system by measuring the signal strength at a positioning antenna. When the signal strength received from the satellite is above a threshold, the communication device 110 determines a feasibility of an Assisted Global Position System, AGPS. When the AGPS is feasible, the communication device initiates an AGPS session for obtaining the location information using an acquisition assistance data and sends the location information together with other MDT data to the MDT server.

摘要： A method and apparatus determines if a location fix received by a mobile station using a non-GPS location techniques is accurate. Location results obtained using the non-GPS location technique or techniques are treated as accurate if they are verified as being within an error margin obtained from a trusted source of location information such as a GPS positioning system. Non-GPS Location information may be obtained from a signal transmitted by the base station, which signal includes the base station location. The non-GPS location information may also be obtained from a backend service associated with the wireless network that includes the base station.

摘要： A method and apparatus for generating and use of a position location reference signal that allows a receiver to receive position location signals from relatively weak signal generators when in the presence of a strong signal source. The position location reference signals from multiple sources can be synchronized to occur within a scheduled time slot of a time division multiplexed communication system. During the scheduled time slot, each signal source can configure a transmission that includes a media access control address that corresponds to a value reserved for position location signals. Each signal source also configures the transmission to include a position location reference signal that corresponds to the signal source. The position location signals from each of the signal sources is positioned to occur at a time within the data portion of the scheduled time slot that no neighboring signal source transmits its corresponding position location signal.
