Abstract
A serving gateway updates location information for a mobile device based on information in an update bearer request. The serving gateway receives a first update bearer request for a mobile device. The first update bearer request includes a first address associated with a micro cellular service base station to which the mobile device is in communication. The micro cellular service base station is associated with a physical location. The serving gateway sends a location notification to a location server, indicating that the mobile device is physically near the micro cellular service base station. The serving gateway receives a second update bearer request for the mobile device including an address associated with a macro cellular service base station. The serving gateway sends another location notification to the location server indicating that the mobile device is no longer at the physical location of the micro cellular service base station.
