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

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

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

1. Media is uploaded to the server
2. Media is delivered to the receivers
3. Adaption is used when needed

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

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

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

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
