摘要： A system and method for utilizing internet protocol (IP) mobility messages and authentication, authorization, and accounting (AAA) messages in a communication system is presented. The communication system comprises a data network coupled to a visited network, a home network, and a service broker, where the visited network and the home network are each coupled to an access node. A serving mobility manager (SMM), which is located in the visited network, receives a user request for information via the access node. A local AAA, which is coupled to the SMM and located in the visited network, queries the service broker to determine the user's home network. The service broker is coupled to the visited network and the home network. A service broker AAA server, which is located in the service broker, contacts a home AAA server, which is located in the home network. The service broker AAA server establishes a trust relationship between the visited network and the home network by utilizing an extension of the IP mobility messages. These IP mobility extension messages are combined with the AAA messages to provide mobility functionality to the AAA messages. A home mobility manager (HMM), which is coupled to the home AAA server and is located in the home network, transmits to the user the information via the data network, the SMM, and the access node using the trust relationship.

摘要： Disclosed is a buffer management method for a mobile node in a mobile IP telecommunication network. The buffer management method supports a handoff of the mobile node from a first agent of a first network to a second agent of a second network. The method begins upon initiation of the handoff. A first message is sent to the first agent requesting the first agent to buffer any packets being sent to the mobile node. While the buffering is being performed, the handoff may be completed to the second agent. Once the handoff is complete, a second message can be sent to the first agent requesting the first agent to forward the buffered packets to the second agent.

摘要： A system and method is provided for seamlessly switching between different network access technologies without interrupting active network applications or sessions. A Network Access Arbitrator (NAA), which contains a virtual network adapter driver, resides between a Data Link Layer and a Network Layer of the standard OSI-7 Layer Protocol Stack for controlling necessary switching between different network access technologies. Since all network applications are controlled by layers residing on or above the Network Layer, all applications using network services provided by the Network Layer will continue their active network sessions or applications without disruption, as the NAA switches between different network access technologies.
