3GPP All-IP Vision and Implementation Roadmap

The document outlines the roadmap for transitioning to an All-IP network, focusing on service creation, scalability, security, and global roaming. It addresses issues related to mobility management and call control models, aiming for seamless integration and enhanced support for various technologies. The roadmap emphasizes the importance of open interfaces, backward compatibility, and IPv6 migration, ensuring a smooth transition to a more advanced network architecture.

  1. 3GPP ”All-IP” visionLong and short term • What do we want to obtain ? • How to get there (phasing) ? • What do 3GPP need to do ? • Issues to be resolved

  2. What do we want to obtain ? • Establishment of a flexible service creation environment • Quick Service/Application creation • APIs to allow for third party applications • Gain from Internet Services • Gain from Intranet Services • Utilisation of Toolkits • Real time including Multimedia services • Scalability

  3. What do we want to obtain ? • Independence of access type • Seamless services • Common Services development • Commonality between private and public networks • Potential for fixed mobile convergence • Separation of Services, Control and Transport when beneficial • Integrated O&M • Leverage IP technology cost factor without compromising quality or performance

  4. What do we want to obtain ? • Open interfaces to ensure a multi-vendor environment • At least same level of security as in state of the art mobile networks • At least same level QoS as in state of the art mobile networks • Respect spectrum efficiency • Voice services, and other relevant legacy services

  5. What do we want to obtain ? • Maintain and enhance Global Roaming • Minimise the number of options in the standard

  6. How to get there ? • Hybrid CS and PS network will exist in the next release(s) • Real time multimedia services in PS domain • Streaming • Service control • Multimedia call control model • Ensure backward compatibility • Service continuity – for relevant services • Roaming between different releases of 2G and 3G • Define relevant handover between releases of 2G and 3G

  7. How to get there ? • Service ”transparency” across domains for common services • Ensure roaming across domains • Enable service creation across domains • Establish common service environment across domains • Enhance support for VHE, OSA and Toolkits

  8. How to get there ? • Study and implement separation of service, control and transport • Enable IP transport (Interfaces to be decided) • Enable signalling over IP • Enable MAP over IP • Ensure sufficient address space • Support for charging and billing

  9. What do 3GPP need to do ? • Establishment of workplan for in R00 • Identification of content of in R00 • Including enhancements to CS and PS domain • Covering all of TSGs • Establishment of detailed requirements • Establishment of longer term architecture as part of R00 • Detailed specification in TSGs and WGs

  10. What do 3GPP need to do ? • Identify potential reuse of work of other bodies • Co-operate with other bodies • IETF – Action required ! • ITU • Other groups with similar interest • MWIF, 3G-IP, 3GPP2, .....

  11. Issues to be resolved • Which Mobility Management model(s) • Which Call Control model (H.323, SIP, H248, ... ?) • Study enhancement to GTP tunneling to harmonise with mobile IP and IPv6 mobility • IP version to use – IPv6 ? • How to migrate to IPv6 ?

  12. Issues to be resolved • Where to use IP transport ? • Core network • Iu interface • UTRAN • Uu Interface • Requirements for naming and addressing
