Abstract
A method of determining the location of a mobile device in a communications network having a plurality of nodes, one of the plural nodes serving the device. Observed positioning measurements for a mobile device may be received from the serving node and uplink enhanced cell identification (E-CID) positioning measurements received from the mobile device. One or more ranges between ones of the plural nodes and the mobile device may then be determined as a function of the received observed positioning measurements and the received uplink E-CID positioning measurements. A geographic location of the mobile device may then be estimated as a function the determined one or more ranges.
