Patent ID: 8391894

Claim:
A method comprising: receiving, at a location agent (LA) located within a base station of an internet protocol (IP)-based wireless network, a location measurement radio request message, from a location controller (LC), the location measurement radio request message to request at least one radio parameter of a mobile station (MS) within the wireless network, wherein the at least one radio parameter comprises a frame number, sub-channel number, symbol range, or symbol offset; transmitting, from the base station, a request to the MS for a list of one or more neighboring base stations; receiving, from the MS, the list of one or more neighboring base stations; transmitting, from the LA, a location measurement radio response message, to the LC, that includes the at least one radio parameter for distribution to at least one other LA, the at least one other LA being located within a different base station of the one or more neighboring base stations; receiving, at the LA, a signal sent by the MS, the signal being sent based on the at least one radio parameter wherein receiving the signal comprises receiving at least one protocol data unit (PDU) sent from the MS as an uplink (UL) reference signal; and measuring, at the LA, the signal sent by the MS to obtain a location measurement, wherein measuring the signal comprises analyzing the at least one PDU to obtain the location measurement and wherein the location measurement is not a Global Positioning Satellite (GPS) location measurement; and transmitting, from the LA, the location measurement to the LC for use in calculating a location of the MS.
