摘要： A method and system are disclosed for determining the distance between a radio receiver (RX) and a radio transmitter (TX) by uplink time measurements, whereby uplink messages are transmitted by the transmitter (TX) and used primarily for position determination. In one embodiment, the uplink messages are intra-cell handover messages if the transmitter (TX) is a component of a mobile radio terminal which is operating in accordance with an existing TDMA standard. In a second embodiment, the uplink messages are a new type of message transmitted in time slots not used by the mobile radio terminal and preferably, also not used by other mobile radio terminals in the system, if the transmitter (TX) is a component of a mobile radio terminal which is operating in accordance with a new or emerging TDMA standard. The evolving GSM radio air-interface standard is an example of such a TDMA standard.

摘要： A method and apparatus are disclosed for determining more accurately, in a radio environment with time dispersion, the distance between a radio receiver and radio transmitter, by special processing of received radio signals that have been transmitted repeatedly from the same radio transmitter and are possibly subject to multipath propagation. The Time of Arrival (TOA) of the received radio signals is repeatedly estimated using channel power profiles. A TOA value near the minimum occurring TOA is selected wherein each estimated TOA is derived from incoherent integration of a randomly chosen number of the received bursts having the same known bit sequence, in order to eliminate the influence of noise.

摘要： In a mobile telecommunications network, a mobile station (MS) is configured to generate and uplink transmit position measuring data prior to and/or during a call connection, without noticeably interrupting the user or degrading the quality of service provided. Position measuring data can be uplink transmitted over an idle traffic channel during a call set up operation for a brief moment while the call connection is being completed. Position measuring data can also be uplink transmitted during a call by selectively stealing data positions or burst positions in the uplink signal. The position measuring data is received by a plurality of base stations and uplink signal characteristics are measured and collected. The measured uplink signal characteristic data from several base stations is then used to determine a current approximate geographical location of the mobile station.

摘要： Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, positioning may be supported by a location server that can reside in different entities. In one design, the location server may obtain positioning information (e.g., measurements) for a target device via a common positioning protocol. The location server may use the common positioning protocol regardless of where it resides and may communicate with other entities via this protocol. The location server may determine location information (e.g., a location estimate) for the target device based on the positioning information. In another aspect, positioning may be supported by transporting multiple positioning messages together. In yet another aspect, positioning may be supported by transporting a positioning message containing multiple parts defined by different organizations. In yet another aspect, positioning may be supported with shared measurement data units and/or shared assistance data units that may be applicable for different positioning methods.
