Connectivity AA resources (including QoS) in the access network (NAP, RNP) CP Combined in today’s fixed networks, separate in mobile and WiMax networks 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 Three types of AA

  9. companion papers and presentations 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” • 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
