  2. Contents • Ambient Networks • Media Delivery • Thesis Tasks • IMS • Concept development • Concept implementation • Feasibility Study • Conclusions • Future Work

  3. Ambient Networks • A project for mobile and wireless systems beyond 3G • Designs an affordable and scalable mobile communication network, that opens up new ways to communicate, for billions of people and devices • Aims at the definition of a ubiquitous Control Space (Ambient Control Space, ACS) applicable for various types of networks • Promotes network intelligence and the optimal use of network resources. Provides ways to overcome technology differences and operator boundaries

  4. Ambient Media Delivery Media Server Media Client Media Port 3G WLAN 3G WLAN

  6. Ambient Media Delivery Principles • The network complexity is hidden from the users and applications with abstractions • The network provides the routing, content adaptation and caching which meet the user needs • The routing is adapted according to the changes in the network • The complexity increases only in the transcoders (media ports) and not in the end devices

  7. How to realize these concepts? ? The Ambient Networks project provides concepts without relations to the current network architecture

  8. Thesis tasks • Literature Study • Ambient Networks • Media Delivery • IP Multimedia Subsystem • Concept Development • Ambient Networks Media Delivery in the IMS • Concept Implementation • Assembly of the IMS testbed • Feasibility Study • Evaluation of the Results

  9. IMS Architecture • A part of the 3GPP Network Architecture • Designed to deliver IP multimedia services for mobile phone users

  10. Developed Service Concept - AN Media Server Media Client 2. Media is delivered to the receivers Media Client 1. Media is uploaded to the server Media Port Media Client 3. Adaption is used when needed

  11. Developed Service Concept - IMS ControlData Application Server UE P-CSCF UE S-CSCF P-CSCF MRF UE

  12. Concept Principles • The research in this thesis concentrated only on the Control Part of the solution • All signaling is based on SIP • Sender uploads the media to a server • Uploaded content is identified with a Media Stream URI • The possible receivers are notified about the content • The receivers may initiate a download sequence with the Media Stream URI

  13. Signaling example - Upload

  14. Feasibility Study • The possible components for an IMS testbed were searched  A combination of Fokus Open Source IMS Core and Ericsson Service Development Studio was used • Unfortunately no suitable MRF emulation was found  A MRF emulation will be developed and added in the future • The control part of the model and its feasibility was studied

  15. The Implementation Client IMS Core:- S-CSCF- I-CSCF- P-CSCF- HSSbind for DNS Application Server WLAN Own contribution: Configuration of the system, Software development for the Client and the Application Server, Service Trigger for the HSS

  16. Conclusions • For the implemented parts of the Ambient Networks Media Delivery Concept, IMS as an implementation base works • The research has to be continued to be sure of the whole concept • The platform for the client and server solutions was not found as flexible as needed • Difficulties not related to IMS standards but internal functions of the platform • The case MRF • No flexible emulations available • The concept of MRF (control, capabilities) still evolves in 3GPP

  17. Future Work • Step 1: Add the user plane • Step 2: Add the MRF • Step 3: Include more IMS domains • Step 4: Include other access types • This thesis was the first step of a bigger project
