Abstract
Systems and methods determine the location of user equipment (UE) in a radio access network (RAN). A network device collects UE location indications and corresponding received signal strength measurements for wireless access stations concurrently visible to cooperating UE devices at the indicated locations. Each UE location indication and corresponding received signal strength measurements provide a data point. The network device assigns signature areas having the same combination of the concurrently visible wireless access stations; identifies multiple clusters of data points in the signature areas; assigns a location value, which represents a geographic area, to each cluster of the multiple clusters; and determines an estimated location of another UE device, wherein the estimated location includes the location value of one of the multiple clusters based on concurrently visible wireless access stations and corresponding received signal strength measurements reported by the other UE device.
