Provides ways to overcome technology differences and operator boundaries

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level 2-5 20 pt © Ericsson AB 2007Outi Koski2007-03-2616 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
