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
