Agenda Standardization MSFORUM / ETSI TISPAN Towards Class-5 VoIP Future trends
ETSI NGN Overview Standardization Activities The ETSI TISPAN working group started to work on the NGN Architecture in December 2003: TISPAN = Telecommunications and Internet converged Services and Protocols for Advanced Networking Focus on enhancing the IMS 3GPP for fixed line access Will (some want) for PSTN / ISDN Replacement Support of Advanced Multimedia Services TISPAN Release 1: 2nd half 2005 - based on 3GPP IMS release 6
3GPP and ETSI Common NGN Architecture Rel 5. mobile fixed 3GPP ETSI IETF SIP SIP IMS Rel 6. SIP IMS 2H/2005
NGN Standards: MSF Architecture Release 2, TISPAN NGN
Target of TISPAN NGN architecture: New end-user services for SIP users independent of access method Push and Talk, IM* and Chat Converged Address Book Converged Centrex Services Dual Mode Handsets Voice over IP Video Telephony and Entertainment...... Seamless services between fixed and mobile users will be the key for operators to gain an edge over competitors. * IM Instant Messaging
Exploiting synergies with a converged infrastructure based on IMS Separated mobile and fixed domains Today: - repeated vertical integration - replication of functions - lack of correlations - no synergies Application 1 n Common application and session control layers IMS: one-time integration Application 1 n Authentication Authentication Single sign-on Specific Billing Specific Billing One Billing Specific database & integration per application Specific database & integration per application Common network integration & global user database Specific O&M Specific O&M Common O&M One single network architecture for FMC supports operators to reduce their total cost of ownership.

VoIP evolution path Field proven VoIP applications Class 4 VoIP networks VoIP over Cable networks following (Euro) PacketCable standards Voice over Broadband (2nd line service with reduced features) New VoIP application cases gaining popularity: Class 5 VoIP networks via 2 alternative methods EMULATION: H.248 / V5.2 VoIP centralized Access gateways (with/without ADSL/GPON) for VoIP Class-5 without changing end-user equipment SIMULATION: SIP Endpoints for enhanced-voice over Broadband / FMC scenarios via any access (ADSL, WiMAX etc)
Drivers towards Class-5 in VoIP Commercial drivers Carriers focus again on the neglected residential segment for universal service obligation or advanced services Outdated access voice equipment / poor local loop status in some carriers Local loop competition, VoIP usage beyond cheap transport for long-distance Metro Ethernet and IP/MPLS networks available / planned in most carriers Technical enablers Access gateways for VoIP Class 5 without changing end user equipment: Metropolitan and Rural scenarios. SIP Endpoints for Voice over Broadband / FMC scenarios. Multimode SIP terminals (DSL, WiFi, VoIP, WiMAX, GSM/UMTS combinations) for mass market expected by terminal vendors. Session Border Controllers for security SIP Application Servers (ISC interface to IMS S-CSCF)
