摘要： For position determination with peer-to-peer communication, a target terminal broadcasts a request for assistance in determining its position. At least one ranging terminal receives the request. Each ranging terminal sends a response with a time of arrival (TOA) measurement for the request and the position of the ranging terminal. For two-way peer-to-peer, the target terminal receives at least one response from the at least one ranging terminal, obtains a TOA measurement for each response, estimates the distance to each ranging terminal based on the TOA measurement for the request and/or the TOA measurement for the response, and computes a position estimate for itself based on the estimated distance and the position for each ranging terminal. For one-way peer-to-peer, a network entity receives at least one response from the at least one ranging terminal, computes a position estimate for the target terminal, and sends the position estimate to the target terminal.

摘要： A hybrid position determination system is disclosed. A mobile device may determine a number of pseudo ranges based on a first position determination system, such as a Global Positioning System. In instances where the position of the mobile device is underdetermined because of an insufficient number of satellite pseudo ranges, the mobile device shares position information with other devices. The other devices may include other mobile devices. A first mobile device may determine its position based on an underdetermined number of satellite pseudo ranges by determining pseudo ranges to other mobile devices. In other embodiments, the number of satellite pseudo ranges may be insufficient to generate an absolute position determination of a single mobile device. In this underdetermined condition, mobile devices may determine a common location of the group or may determine a relative positioning of members of the group.

摘要： Techniques to detect whether or not a remote terminal is under the coverage of a repeater within a wireless communication network, which may be based on (1) a list of base stations expected to be received while under the repeater's coverage, (2) the characterized environment of the repeater, and/or (3) the propagation delays for a transmission received at the remote terminal. Additional ambiguity resulting from being under a repeater's coverage may also be accounted for and/or compensated by (1) discarding time measurements from repeated base stations, (2) adjusting the processing for position estimation to account for the additional ambiguity due to the repeater, (3) computing a series of position estimates based on multiple transmissions received from the same originating base station and selecting the best estimate, and/or (4) computing a series of position estimates based on multiple transmissions from multiple originating base stations and selecting the best estimate.

摘要： There is described a method of providing a positioning service for plural terminals operating in a communication network which may, for example be a GSM telephone network. The terminals have receivers for receiving signals from transmission sources. In the method measurements of the signals received from one or more of the transmission sources by the receivers are made and the measurements transferred to one or more data nodes. At the data node(s) one or more records of one or more of the measurements are created and at least some of the records are transferred to one or more computing nodes. At the computing node(s) a table of the records transferred to the computing node is maintained and a computation is carried out, using at least part of the table, from which the positions or states of motion or relative positions or relative states of motion of said plural terminals and the transmission time offsets of the transmission sources are extractable.
