Abstract
A plurality of low powered beacons are selectively placed throughout a serving mobile telecommunications network without connecting the beacons and the telecommunications network therebetween. Each of the beacons independently transmits identification data uniquely identifying itself. An application module and a mapping table correlating each identification data with the location of the corresponding beacon are associated with the serving mobile telecommunications network. As a mobile station travels within the serving mobile telecommunications network, the mobile station receives the identification data broadcast by the closest beacon located thereto. In connection with a call connection, the mobile station then transmits the received identification data to the serving mobile telecommunications network. By determining the location of the identified beacon, the mobile telecommunications network then determines that the mobile station is located approximate thereto.
