3 Agenda MGW and MRFP components in IMS architecture Why/how IMS provides advantages in multimedia service delivery MGW and MRFP key IMS blocks Requirement summary for MGW Requirement summary for MRFP Central role of enabling silicon (SoC) Meet the challenges of 3G-NGN MGW (IMS MGW/MRFP) Requirement implications of building IMS MGW/MRFP Steps of building an IMS gateway with low risk and fast time-to-market Hardware: system, board, silicon Software: common system solution approach and advantages over traditional approach

4 Fixed Mobile Broadband (FMB) Convergence and IMS Drivers Convergence Fixed, mobile, broadband Convergence is reality IMS motivations New services and revenue Fast time-to-market Harmonized (any terminal) Lower infrastructure cost IMS technology components IP (while keeping legacy) SIP Multimedia high compression/ quality and adaptation Any access and IMS arch support Fixed Broadband Mobile

Media gateway function (MGF)* The residential MGF (R-MGF) is located on customer premises The access MGF (A-MGF) resides on the network operator s premises (IP access network or core network) The trunking MGF (T-MGF)** resides in the boundary between an IP core network and the PSTN/ISDN Media resource function processor (MRFP) Specialized resource processing functions beyond those available in media gateway functions Multimedia conferences Multimedia announcements IVR capabilities Media content analysis * From Rel 1. Doc ** Same as IMS-MGW in 3GPP

9 The New 3G-NGN MGW Functionality: Other Requirements and Trends 3G-NGN MGW architectural directions Multi-role and application: software configured Same GW can be configured for wireline or wireless NGN MGF and/or MRFP Centralized and decoupled from access type, with advantages of: NGN cost savings Time-to-market Multi-vendor interoperability Diverse functionality beyond basic VoIP (EC, codecs, voice/fax/modem VoIP) Conferences, gaming, CALEA, IP/ATM interworking, transcoding Voice enhancement, protocol conversion, IPv6, QoS (TOS, MPLS)

10 Silicon Requirements for 3G-NGN Beyond basic features: codec/fax, EC, telephony, class (conf., caller ID) MRFP and media server features Announcements and recording: ringback tones, etc. IVR: feature programming, feature invocation, voic , etc. Bridging: push-to-talk, three-way conferencing, rich multi-way conferencing, chat calls Video and rich video conferencing (roadmap) Speech recognition, text-to-speech, speaker verification (extern) New codecs and voice enhancement algorithms are complex For example, WB-AMR/AMR+/AAC (3GPP), EVRC/SMV (3GPP2) TTY/CTM Codec transcoding with lower delay and complexity G.VED (noise reduction, acoustic EC, ALC, TFO) Voice quality monitoring Voice recognition Requires DSP MIPS

11 Silicon Requirements for 3G-NGN NGN systems require complex network processing RTCP-XP, framing (e.g., 3G AMR), 3GPP TFO/TrFO, rate adaptation (Iu) Complex coupled NP (ATM/IP) and non-dsp processing: Iu, TFO/TrFO, CALEA Single-chip ATM-IP interworking with and without transcoding Fortified against DoS and network impairments Distributed network processing is a scalable solution Silicon architecture and horsepower with low power Few vendors ready for the challenge Powerful, tightly-coupled DSP-NP, delay Simultaneous COMMON single software support for multiple networks is an important differentiation Look for silicon vendors that can do this: What s the capacity? At what cost?
