Diameter Session Management in Diameter Application Protocols Diameter session consists of one or more AAA transactions related to a user, but the current Diameter Base Protocol can only handle static users -> There is no session mobility. In Diameter Mobile IPv4 Application, a new Diameter Session is suggested to be set up when the user changes his access router. But this is not so effective, in the sense of the round-trip of AAA messages and scalability. REQUIREMENT: A generic Diameter Session Mobility Mechanism that enable users to change their access router without affections to their home servers. |
