device for reception of positionsanforderungen

摘要

A device (103) for making a locationing request (REQ), comprises:receiving means (201), adapted to:-i) receive base station identities ({BS; BS2, BS3}) from a base station (BS) of a cellular network (101); and-ii) receive a timing signal (ts1; ts2; ts3) from at least two base stations (BS; BS2, BS3) that have identities corresponding to identities ({BS; BS2, BS3}) received;means (205) for measuring time of arrival (T1; T2; T3) for at least two timing signals (ts1; ts2; ts3);means (205) for generating a locationing request (REQ), the locationing request (REQ) comprising information (MEAS) derived from the at least two times of arrival (T1; T2; T3) measured; andmeans (207) for sending said locationing request (REQ) to a base station (BS); wherein:the means (205) for generating a locationing request (REQ) is further adapted to write an identifier (IMEI; IMSI) to the locationing request (REQ), the identifier (IMEI; IMSI) identifying the device (103) or a subscriber module (211) in the device (103); andthe means (207) for sending the locationing request (REQ) are adapted to send the locationing request (REQ) to the base station (BS) after the device (103) has locked to the base station (BS) but before the device (103) has logged into the cellular network (101).
