Dynamically updating a home agent with location-based information

摘要

Methods and computer-readable media are provided to dynamically update a home agent with location-based information for a mobile device such that a third party, such as a law enforcement agency, may access the information to determine a location associated with the mobile device and, therefore, with the user of the mobile device. A signaling message is sent to a packet-routing component. The signaling message contains location-based information for a communications session. A transaction update is sent from the packet-routing component to the home agent each time the location-based information is updated, such as when the mobile device enters a new coverage area. A binding table is populated with the updated information. An acknowledgment is then sent from the home agent to the packet-routing component indicating that the information has been updated in the binding table. The third party is now able to access the location-based information via the home agent.
