1. A method, comprising:
- reducing, by a device comprising a processor, an initial search area associated with base station devices to a search area associated with a base station device of the base station devices determined to be associated with signal strength information that satisfies a condition, wherein the signal strength information is obtained from a mobile device measuring a signal strength of signals generated by the base station device;
determining, by the device, a distance from an approximate location of the base station device associated with the signal strength information that satisfies the condition, wherein the distance is based on the signal strength information for the base station device, and wherein the condition being satisfied comprises the signal strength information being determined to represent the signal strength that is greater than a defined threshold signal strength;
determining, by the device, that the device is within a defined distance to the base station device; and
forgoing, by the device, performing scanning of bin regions representing a search area based on the determining that the device is within the defined distance.

Abstract
Downlink signal strength measurements from base stations (BSs) are reported by mobile devices to facilitate mobile device locating. A system receives the signal strength information and determines whether the mobile device is within a selected distance from any of the BSs in response to detecting that signal strength information for one of the BSs is greater than a predefined value. The system determines an area over which to search for the mobile device if the system fails to detect that the signal strength information for any of the BSs is greater than the predefined value. The area over which the search is performed is an intersection of all regions determined by the signal strengths of the BSs.
