What is NGN ?

� The “Converged” Next Generation Network will provide:� A multi-service, multi-protocol, multi-access, IP based network -

secure, reliable and trusted� Multi-services: delivered by a common QoS enabled core network. � Multi-access: several access networks; fixed and mobile terminals.

� An enabler for Service Providers to offer:� real-time and non real-time communication services � Flexible environment for rapid delivery of new services

� Nomadicity and Mobility� of both users and devices� intra- and inter-Network Domains, eventually fully between Fixed

and Mobile networks

“My communications services” always reachable, everywhere, using any terminal .

Page 4: NGN Architectures

Business drivers for NGN

� OPEX cost reduction

� Revenue enhancement

� Coping with various form of disruptive competition (eg supply of VoIP)

� Market saturation of existing services

� Rapid / cost reduced supply of new services

� Renewal of old networks (e.g. PSTN)

� Deployment of single networks for any access networks

Mobile Networks History

� 1G: 1st Mobile Networks: 80's � Analog networks� Proprietary or national solutions :� No compatibility � Very expensive for the user� Very low penetration

� 2G: 82: Creation of "Groupe Spéciale Mobile" within the European Conference of Postal and Telecommunications Administrations (CEPT)� 90-91 : The GSM Phase 1 recommendations are frozen� 92 : First GSM networks in operation� 94 : GSM Phase 2 recommendations publication

� 2.5G: 1997: GPRS – EDGE� 3G: 2000: UMTS� 2002: IMS (Release 5)� 3G+: 2005: HSDPA-HSUPA� 4G: Currently: Toward LTE/SAE � In addition

� UMA/GAN� I-WLAN� FemtoCell

Page 8: NGN Architectures

Toward IMS � Why IMS ?

� Evolution of Mobile Networks � Use of CS and PS Networks � More Bandwidth � Delivery of data services with voice on CS

� Emergence of multimedia services � Growth and large penetration of Internet � Development of content applications � Competitive voice services like Skype, .. � Access to Internet from different network access

� Mobile Operators � Gain control of the extended value chain, otherwise they will become bandwidth

provider � Keeping ownership of subscribers � Extend revenue and potential profits

� The main advantage of mobile operators� Experience of service delivery � Value added services, not only voice but more …� Quality of services

� IMS� 1st step towards all IP Network Architectures � SIP based multimedia control subsystem independent of network access� Offer SIP converged and multimedia services� Single sing-in features for services,

Page 9: NGN Architectures

What is IMS?� An enabler for Service Providers to offer:

� real-time and non real-time communication services � Flexible environment for rapid delivery of new services

� Nomadicity and Mobility� of both users and devices� intra- and inter-Network Domains, eventually fully between Fixed and

Mobile networks� IMS (IP Multimedia Subsystem) specifications are being developed by 3GPP

(3rd Generation Partnership Program)� IMS will form a major part of a future NGN (Next Generation Network) environment

(eg in ITU-T specifications)

� IMS is a collection of core network functional entities for the support of SIP (Session Initiation Protocol) based services.

� IMS builds upon other standards eg IETF – SIP, SDP (Session Description Protocol), Diameter (user authorization and subscriber service profile access), AAA (Access, Authorisation and Accounting)

� IMS is being accepted and incorporated into specifications being produced by other standards bodies – eg 3GPP2, ETSI/TISPAN, OMA.

� IMS Architecture and SIP can be extended to support new services

“My communications services” always reachable, everywhere, using any terminal on any network access

TISPAN and ITU-T architecture relationship

� Both architectures comply with the principles defined in Recommendation Y.2011 (w.r.ttransport/service functional split).

� The ITU architecture Y.2012 (FGNGN-FRA) should be considered as a generic architectural framework while the ETSI TISPAN NGN functional architecture should be viewed as a particular – subsystem oriented - realisation of this framework.

Page 61: NGN Architectures

ETSI TISPAN NGN Architecture Design

� Consistent with the ITU-T framework

� A sub-system oriented approach, enabling: � The addition of new subsystems over the time � To import (and adapt) subsystems from other standardisation

bodies.� Flexibility to adjust a subsystem architecture with almost no

impact on others.

� IP connectivity is provided using two subsystems over IP transport resources (DSL access & aggregation + IP backbone):� NASS: Network Attachment Subsystem� RACS: Resource and Admission Control Subsystem

Page 74: NGN Architectures

PSTN/ISDN Emulation Subsystem (PES)

� PSTN/ISDN Emulation = Provision of PSTN/ISDN services to legacy terminals connected through a gateway.

� Two competing approaches:� Softswitch-like approach� IMS-based approach (TS 182 012)

� IMS-Based approach: Avoid a dedicated infrastructure for supporting PSTN Emulation� In the mid/long term, Emulation-based configurations are

likely to be substituted by Simulation-based configurations.

� Act as an MGC for controlling media gateways functions located in residential and access gateways.

� Perform signalling interworking between SIP and analogsignalling (through H.248 signals and events).

� Manage SIP registration procedures on behalf of legacy terminals connected behind the media gateways.

� Provide basic feature logic for � Determining end of dialling;� Selecting a dial tone� Processing mid call events (i.e. flash-hook), collecting digits

NGN Management

Conclusion

Page 80: NGN Architectures

NGN Environment to be Managed

� Based on Packet-based transfer� Common control functions supporting a wide range of applications –

via session services� Support for complex value chains , multiple trading partners /

business models (eg B2B interactions)� Support for a wide range of services , applications and mechanisms,

[including real time/ streaming/ non-real time and multimedia services]� Broadband capabilities with end-to-end QoS (Quality of Service)� Inter-working with legacy networks via open interfaces� Generalized mobility, with converged services between fixed/mobile� Personalization of Services in a component-oriented environment� Variety of customer identification schemes (eg Role-based access)� Independence of service-related functions from underlying transport� Compliant with all Legal and regulatory requirements

[Emergency communications, security, privacy, lawful interception, etc.]

Page 81: NGN Architectures

NGN OSS Architecture – Characteristics

To fulfill the NGN business and technical vision, design of the OSS architecture must have the following characteristics:

� All systems must embrace a similar component-based , service-oriented architecture “SOA” – defined in a technology neutral form

� Utilise a common information architecture across all management applications so that :

� information can be shared across multiple areas of Management� capabilities can be developed for collecting end-to-end service

measurement data (eg for SLA support).� framework provided for policy-based management for existing or yet to

be defined services.

� OSS solutions must be developed according to a common business process framework

� Network Technologies managed in a common way, Services Managed independently of the Network technologies

Difference between 3GPP and TISPAN SuM Requirements

3GPP � All (Subscription) Service Profile

Information ultimately held in Home HSS� Distributed by signalling to VHSS� Each user equated to a SIM /UICC

Page 91: NGN Architectures

Difference between 3GPP and TISPAN SuM Requirements

TISPAN� Providers of Access and Service can be different� Hence HSS functionality split between

� IMS (User Profile Service functions –UPSF)� NASS (Profile Data Base Function – PDBF)

� Configuration of the E2E service requires� Transactional and referential integrity between UPSF and PDBF� Synchronisation of UPSF/ PDBF with providers OSS (Service

Mngt)� Ability to synchronise SP SuM Profiles across B2B interfaces

� Broadband access means on one access line � multiple terminals� multiple Users � multiple Customers

� Distinguish between Customer, Subscriber and User� Different/No Authentication -No equivalent of SIM/UICC
