Title:
COMMUNICATION HANDOVER METHOD, COMMUNICATION MESSAGE PROCESSING METHOD, PROGRAM FOR CAUSING COMPUTER TO EXECUTE THESE METHODS, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2005/081560
Kind Code:
A1
Abstract:
There is disclosed a technique that a mobile terminal can rapidly and continuously receive, after a handover, an additional service (such as QoS guarantee) which has been received before the handover. According to the technique, the mobile terminal (MN(10)) decides to perform a handover between subnets according to a predetermined condition, generates NCoA, and acquires information (adjacent mQNE information such as an IP address of mQNE) on the mQNE (node capable of modifying the QoS route) (41) adjacent in the QoS route of the MN (10). The MN transmits an FBU message and transmits the adjacent mQNE information to oAR (21). The oAR transfers the received adjacent mQNE information together with an HI message to nAR (31). According to the adjacent mQNE information, the nAR establishes a (C)QoS route for the MN to/from the mQNE.
