1. Strategies towards Telecommunications Convergence Ray Adensamer Senior Manager, Product Marketing RadiSys Session IMS-08: IMS and FMC September 12, 2007

2. September 10-12, 2007 Los Angeles Convention Center Los Angeles, California www.ITEXPO.com 2 Topics Common Definitions of Telecommunications Convergence –Convergence as an end-user experience –Convergence in the service delivery network infrastructure Strategies towards Telecommunications Network Convergence –Core Network Convergence –Access Network Convergence –Service Delivery Convergence –Hardware Platform Convergence

3. September 10-12, 2007 Los Angeles Convention Center Los Angeles, California www.ITEXPO.com 3 Fixed Mobile Convergence “A clear trend is emerging in the form of FMC - A fixed and mobile telephony convergence. The aim is to provide both services with a single phone, which could switch between networks ad hoc” 1. Example: BT Fusion in UK 1. From www.wikipedia.com (January, 2007) Source: BT website

4. September 10-12, 2007 Los Angeles Convention Center Los Angeles, California www.ITEXPO.com 4 Triple Play “Triple Play” is a marketing term for the provisioning of the three services over a single broadband connection 1. –High-speed Internet, –Television (Video on Demand or regular broadcasts) and –Telephone service over a single broadband connection. Plus…. Wireless Services gives you a “Quadruple Play” Triple Play services are offered by –cable television operators –telecommunication operators. Triple Play focuses on a combined business model rather than on solving technical issues or a common standard. 1. From www.wikipedia.com (January, 2007) This presentation will explore strategies towards achieving telecom network convergence

6. September 10-12, 2007 Los Angeles Convention Center Los Angeles, California www.ITEXPO.com 6 Internet Protocol The Transport Network for Convergence Internet Protocol (IP) is a packet-based protocol. –Packets take different routes through the network, and can arrive at different times. –Higher traffic increases network delays. Different services have different tolerance to network delays –Network delays are tolerable for data services (e.g. file transfers, email, or music downloads). –However, interactive voice and video services require “real-time” response. Optimizing IP network design is important for converged IP services. –The generic Internet has limited (if any) ability to ascertain voice and video packets, hence quality varies significantly. –Carrier IP networks improve use additional techniques, including using Multi Path Label Switching (MPLS), to transmit delay- sensitive packets with higher priority and dedicated capacity.
