6. Roaming in an Unbundled Fixed-Mobile Convergent World BroadBand Europe 2007 Three types of AA Connectivity AA resources (including QoS) in the access network (NAP, RNP) CP Network service AA resources in the network service provider network (NSP), typically IP addresses NSP Application AA service provided by the application service provider (ASP) ASP Combined in today’s fixed networks, separate in mobile and WiMax networks

9. Roaming in an Unbundled Fixed-Mobile Convergent World BroadBand Europe 2007 Conclusion > MUSE FMC architecture covers convergence of networks: coupling of DSL, fiber, WiMaX, 3GPP networks convergence of business role models: “mobility and roaming meet unbundling” companion papers and presentations > FMC has impact on AA: connectivity, network service, application IP addressing arrangements policy control mobility: MIP-based, SIP-based > Try to keep it simple stick to three types of roaming relations stick to limited set of recommended protocols
