1 Mobile Core Evolution to Elena Romero, Sales Manager Ericsson AB Why? IP Multimedia Subsystem () is a standardised architecture (defined by 3GPP/3GPP2) for offering services on the packet domain. It is a generic architecture for offering multimedia services. is independent of Access, supports: UMTS, GPRS, fixed line, WLAN etc. Pre- Communication Communication Voice SMS Instant Messaging Voice SMS Instant Messaging MMS Video Conferencing Application sharing Others MMS 1) Decide on communication mode/media 2) Create content 3) Send/call the chosen person 4) Disconnect and reconnect if changing media 1) See who is available beforehand (presence) 2) See which mode/media to use 3) Contact and create content 4) Change media in real time Ericsson AB Ericsson AB

2 Why - operator perspective? How can solve these issues? Increased competition from VoIP service providers Provide IP Telephony Rapid broadband roll-out due to access deregulation Fight back competitors Wireline & Wireless Operators Secure valuable position in the value chain Be more than a bit-pipe provider Increase ARPU and reduce churn via new attractive services Bundled services Improve net income via reduced costs and new multimedia services Cost efficient solution Ericsson AB The core of Combining the best of two worlds Open, flexible service development ability of the Datacom industry Performance and scalability characteristics of the Telecom Industry Solutions Datacom Industry Telecom Industry Standardized, end-2-end services that are interoperability tested Ericsson AB Ericsson AB

8 Combinational s A combinational service is created by combining a CS speech call and one or more PS media streams The services that are mixed have the same A-and B-party and, when combined, appear as a single task to the end-user Packet Circuit switched Voice Video, data... switched Ericsson AB Broad application spectra Defining services Legacy and value added voice services (IN, Parlay) Standardized services for Mass-market Differentiating services GW CSCF Ericsson AB Ericsson AB

9 What is being said about Comments from previous conferences We will achieve more in 5 years than we have done the last 20! Pre-standard services threats long term business potential European operator Availability of -enabled devices key for success European vendor Our goal - excellence in user experience European operator Ericsson AB Ericsson AB Ericsson AB
