method and device for enabling ip mobility with high-speed and netzwerkintelligenz in communication networks

摘要

An architecture for network layer mobility support, using always on broadband high speed access and a network-based mobility manager, termed as a network server or gateway is disclosed. In order to enable mobility of a mobile node in a communication network, a registration message is received from a first access point (AP) indicating that the mobile node is present in an area serviced by said first access point. A network server then determines whether the mobile node is present within the mobile node's home access point, and routes at least one packet to the mobile node via a first pre-provisioned virtual private network (VPN) tunnel to the first access point if it is determined that the mobile node is present within the first access point, or routes at least one packet to the mobile node via a second pre-provisioned virtual private network (VPN) tunnel to the home access point if it is determined that the mobile node is present within the home access point. This obviates the need of MIP for IP mobility. IMAGE
