What Operators need from NGN Standardisation Stewart Alexander ITU Standards Manager, BT Group WTSA
Summary Business drivers for NGN Requirements for NGN Technical view of NGN What standards do we need for NGN? What do we want from ITU?
WTSA Whats the Current situation? Telecom winter exaggerating the cost of multiple standards – e.g. multiple networks in mobile All telcos under pressure to reduce expenditure on standards Cost of interworking is killing us More and more uses are global (mobile, WLAN, Internet etc) with more and more users travelling. Standards must be global Growing complexity from multiple fora as groups become frustrated with speed of traditional standards bodies Need for a radical drive to the NGN – speed is essential.
WTSA Why do we need an NGN? Make it easier to create new services –Faster –More people can create services Make it easier to buy and use services –Give customers greater choice Make it simpler to deliver and maintain services –Process automation 30-40% cost reduction
WTSA What does it mean? New services –Open APIs and applications platforms –Mobile enabled –Re-usable components/capabilities –Build on broadband capability Cost reduction –Not enough to do efficiencies and automation –Radical network convergence to fewer networks and systems carrying more services
WTSA Cost Reduction Efficiencies and automation not enough –need to enable customers and partners in the service management processes Radical steps required –need closure of legacy networks and systems Have to include future of PSTN (voice) More important to converge in access and backhaul than in core –because opex and capex centred there
WTSA 21 st Century Services Vision A world where all our customers feel empowered and are treated as individuals
WTSA Todays Networks Built on service=technology stove pipes. Every network service has its own network platform: –FR, ATM, MPLS IP VPN, Internet, PSTN etc. We want a converged multi- service platform to deliver all services. B C Internet Frame Relay ATM SDH Cost

WTSA Highest Priority NGN Standards Requirements Multi-service carrier-scale core –enabled by underlying MPLSv2 network 3GPP Architecture –extended to Wi-Fi and fixed Broadband access Session based QoS Session Control –extensions to SIP with full multimedia capability Billing and charging (data interchange billing) between operators Manageability –commoditised componentised OSS Security –authentication across networks / operators Home Gateways/Networks
WTSA What do we need to do generally..? Prioritise. Position fora, regional bodies and ITU into a consistent approach to lead to global standards – an architecture of standards bodies. Support the NGN architecture – will require us to merge over traditional boundaries. Give equal weight to systems and networks
WTSA ITU is important to NGN for: Access Networks – SG15 Core Networks – SG13 Optical Networking – SG15 Spectrum – ITU-R Numbering & Addressing – SG2 Signalling for QoS across multiple networks – SG11 Services and applications – SG16 Security – SG17 NGN Focus Group – to get it started and bring it all together
WTSA Other Important Bodies for NGN 3GPP/TISPAN – IMS ATIS – US carrier requirements DSL Forum – remote management of CPE IETF – IPv6, SIP extensions, MPLS, etc TMF – standardised OSS components Open Mobile Alliance (OMA) – (Mobile) Applications, DRM Metro Ethernet Forum (MEF) – role of Ethernet in transport network IEEE 802.11x – Wi-Fi hotspots
WTSA What do we want from ITU? Global Standards, speedily and efficiently produced How do we get this? A single ITU-T Study Group for core NGN studies A managed release program A co-ordinated ITU-T approach
WTSA Conclusions NGN will only succeed if based on globally standardised components ITU must work with ETSI, ATIS and other fora to achieve standards for NGN ITU can provide strategic focus for NGN standards – but must create SG with sufficient critical mass to address NGN issues
