    1. Outline Wireless Network Architecture Introduction to Mobility management Mobility Management for PLMN Mobility Management for Mobile IP Mobility Management for WATM Mobility Management for Satellite Network Mobility Management Issues Reference

    2. Wireless Network Architecture ITU has specified architecture and system standards for IMT-2000 that include

    3. Wireless Network Architecture Hierarchical Cell Structure

    4. Wireless Network Architecture

    5. Wireless Network Architecture >The CSS also manage connection resource and provide mobility management control functions Global Roaming

    7. Wireless Network Architecture >Terminal mobility refers to the ability of the network to route calls to the MT regardless of its point of attachment to the network. >Personal mobility is the ability of the user to access their personal services independent of the their attachment point

    9. Wireless Network Architecture >Service provider portability allows the user and/or the MT to transcend mobile networks >>Require the coordination of a wide range of service providers, compatibility of mobile networks Radio Spectrum(1995 by ITU)

    10. Wireless Network Architecture >60 MHz is reserved for satellite.

    12. Introduction To Mobility Management Enable wireless networks to

    13. Introduction To Mobility Management Location Management

    14. Introduction To Mobility Management >Deterioration of the radio channel>> intra-cell handoff or inter-cell handoff

    15. Mobility Management for PLMN Two available standards for location management

    16. Mobility Management for PLMN

    17. Mobility Management for PLMN Location registration procedures

    19. Mobility Management for PLMN Call delivery procedures

    20. Mobility Management for PLMN

    22. Mobility Management for PLMN Location management research

    24. Mobility Management for PLMN Handoff management

    25. Mobility Management for PLMN Discussion

    26. Mobility Management for Mobile IP Mobile IP >Allows a mobile node(MN) changes its attachm- ent point from one subnet to another without cha- nging its IP address Operations of Mobile IP > Discovery: MN must be able to find agent>Registration: MN must register with the FA and inform its HA of its movement>Tunneling: HA must redirect datagrams to MN

    28. Mobility Management for Mobile IP Discovery

    29. Mobility Management for Mobile IP Registration

    31. Mobility Management for Mobile IP Tunneling

    33. Mobility Management for Mobile IP Handoff Management

    35. Mobility Management for Mobile IP Discussion>Simultaneous Binding >>HA may send duplicate encapsulated datagrams to MN >>MN may invoke some process to remove the duplicate datagrams>Regionalized Registration >>How many FAs? >>Registration cost problem>Security >>Authentication

    36. Mobility Management for WATM Focus on location and handoff management Location Management

    37. Mobility Management for WATM Handoff Management

    38. Mobility Management for WATM Discussion

    39. Mobility management for Satellite Networks The coverage area of a single satellite consists of small-sized cell , which are called spotbeam Satellite location management>The satellite network environment bring more challenging problems because of the movement of satellite footprints

    40. Mobility management for Satellite Networks Satellite handoff management

    41. Mobility management for Satellite Networks Discussion

    42. Mobility Management Issues Addressing and identification>Because of global roaming, the dynamic bindin- gs between an MT’s address and its identity will change frequently. Database Issues>MT whose home network is the PLMN, but whose current visited network is WATM-based.

    43. Mobility Management Issues Routing Issues>Different networks must be provide different connection information Standardization>Japan,Europe,USA
