  3. An Integrated 3GPP, 3GPP2, and WLANs Testbed • Architectures and protocols of 3GPP, 3GPP2, and WLANs are different. • Harmonization of mobility management is a key for seamless roaming • IP mobility makes roaming possible. • Our testbed: • 3GPP: shipped from ITRI/CCL • 3GPP2: developed by NTHU • WLANs: adopt commercial products

  4. Mobility Supports using Mobile SCTP in 4G Heterogeneous All-IP Core Networks

  5. RAMP: Reconfigurable Architecture and Mobility Management • Incompatible wireless systems will coexist in the near future • IP mobility protocols, 3GPP, 3GPP2, etc. • IP-based but not compatible • How to achieve universal roaming is a big challenge • A universal common core network? • A solution which meets everyone’s requirements • Reconfigurable core network • Reconfigurable mobility management – RAMP

  6. Requirements • Both network and mobile node can choose their prefer mobility management protocols • Mobile node can change its mobility protocol at anytime • Standard IP protocol and IP routing should not be changed • RAMP-unaware network nodes should continue to work with original IP protocols • Mobile nodes in the same domain can use different mobility management protocols

  7. RAMP Architecture • Components • Mobile Node (MN) – collocated with mobile host • Network Node (NN) – collocated with each router • Messages • RAMP Header + Supported Mobility Protocols + Advertisement • RAMP Header + Original Mobility Management Messages • RAMP Header

  8. Basic Idea • RAMP advertisementsent by NN periodically • MN registers with NN using RAMP registration • Thereafter, the network and the MN could decide the most desirable mobility management protocol to use. • The registrations of micro-mobility management protocol and macro-mobility management protocol in RAMP are separated • Flexibility and reconfigurability

  9. NN Architecture

  10. MN Architecture

  11. Relation between RAMP and IP Protocol Stack
