Signal power pattern-based location detection and cell placement
First Claim
1. A method performed by one or more network devices for a radio access network (RAN), the method comprising:
- collecting user equipment (UE) location indications and corresponding received signal strength measurements for wireless access stations concurrently visible to cooperating UE devices at the indicated locations, wherein each UE location indication and corresponding received signal strength measurements provide a data point;
assigning signature areas having the same combination of the concurrently visible wireless access stations;
identifying multiple clusters of data points in the signature areas;
calculating an estimated location for each cluster of the multiple clusters based on the UE location indications from the data points;
receiving, from another UE device after the calculating, a listing of concurrently visible wireless access stations and corresponding received signal strength measurements by the other UE device; and
generating a location estimate for the other UE device by correlating the concurrently visible wireless access stations and the corresponding received signal strength measurements in the listing to one cluster of the multiple clusters within one of the signature areas.

Abstract
A method is provided for one or more network devices to determine the location of user equipment (UE) in a radio access network (RAN). The method includes collecting 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 method also includes assigning signature areas based on groupings having the same combination of the concurrently visible wireless access stations, identifying multiple clusters of data points within the signature areas, and calculating an estimated location for each cluster based on the UE location indications from the data points. After the designating, the method includes receiving, from a UE device, a listing of concurrently visible wireless access stations and corresponding received signal strength measurements by the other UE device, and generating a location estimate for the other UE device by correlating the concurrently visible wireless access stations and the corresponding received signal strength measurements in the listing to one of the clusters within one of the signature areas.

13. A network device, comprising:
-
an interface that communicates with a network; a memory configured to store instructions; and a processor, coupled to the interface and the memory, wherein the processor is configured to execute the instructions stored in the memory to; collect user equipment (UE) location indications and corresponding received signal strength measurements for wireless access stations concurrently visible to cooperating UE devices at the indicated locations, wherein each UE location indication and corresponding received signal strength measurements provide a data point; assign signature areas having the same combination of the concurrently visible wireless access stations; identify multiple clusters of data points in the signature areas; calculate an estimated location for each of the clusters based on the UE location indications from the data points in each respective cluster of the multiple clusters; receive, from another UE device after the calculating, a listing of concurrently visible wireless access stations and corresponding received signal strength measurements by the other UE device; and generate a location estimate for the other UE device by correlating the concurrently visible wireless access stations and the corresponding received signal strength measurements in the listing to one cluster of the multiple clusters within one of the signature areas. - View Dependent Claims (14, 15, 16)
