METHOD AND APPARATUS FOR UPDATING LOCATION INFORMATION OF MOBILE NODE

摘要

PROBLEM TO BE SOLVED: To provide an improved method and an apparatus for location tracking and paging.

SOLUTION: An inactive-state mobile node updates its location information by transmitting a first message via a radio link to an access node. In response to the first message, the access node generates a second update message. The second message includes a mobile node identifier. The second message is received by a tracking agent. The tracking agent updates location information corresponding to the mobile node. When a route of the second message is specified by the mobile node as a form of an IP message using a mobile IP, the route of the second message is specified for a last network attachment point of the mobile node by a mobile IP home agent. Then, the tracking agent is stationed at the last point and interception of the message is performed.
