Aspects of the subject disclosure may include, for example, identifying positioning information associated with a wireless communication device, determining a current location of the wireless communication device based on the positioning information, detecting a location change based on the current location of the wireless communication device, and responsive to the detection of the location change, sending a location change notification to a location management entity. Other embodiments are disclosed.

Passive location change detection system for mobility networks

Methods and apparatus for estimating mobile station location include receiving reported signal strengths or other attachment indicator values from a mobile station. The reported signal strengths are compared with characteristic received signal strength values in a coverage area of a mobile network. A mobile switching center determines if a local function is requested and initiates a location estimation process by a mobile location module (MLM). The MLM receives the reported signal strength contours associated with the attachment points. Based on a comparison of the reported attachment indicator values with characteristic values, the MLM provides a mobile location estimate.

Methods and apparatus for mobile station location estimation

A mobile terminal device that facilitates location services (LCS) in a cellular network. The system, as embodied in a mobile terminal device, comprises a mobile communications component that communicates wireless signals, and a location services component embodied in the mobile communication component to provide positioning information. A location request is received by the mobile terminal device and processed using the LCS server to activate trigger events. A location-tracking report is autonomously generated for each event and transmitted to the requesting client via MLP or the wireless network signaling protocol.
