4 Overview of NGN and Release 1

4.1 NGN overview The fundamental aspects of an NGN are defined in [1]

4.2 Release 1 overview To enable continued development of broadband, it is important to introduce new services to retain and attract new customers which in turn will sustain or generate further revenues. TISPAN NGN Release 1 met the immediate needs of network operators and vendors alike in developing specifications for a feature-rich NGN that supports key capabilities necessary to enable a wide range of multimedia services. Capabilities in support of legacy PSTN/ISDN services (PSTN/ISDN emulation/simulation) and appropriate interconnections to other networks are supported in Release 1 alongside new multimedia services.

The general objective of the first release of all release-based standards is to provide a framework, that provides an extensible platform for future service and architecture development. The objectives for NGN Release 1 were to provide such an extensible platform and architecture, and to demonstrate viability by specifying the details for two significant objectives were set:

• to enable delivery of the services supported in a 3GPP IMS to broadband fixed lines;

• to enable PSTN/ISDN replacement (in whole or in part).

A deployed Release 1 NGN may support either of the above objectives, or both using the same core network, transport, service and applications. Further details of Release 1 can be found in [2].

5 Release 2 enhancements NGN Release 1 is designed to be extensible, allowing new services to be incorporated into the release 1 subsystems, and to enable other subsystems to be defined. This clause describes the enhancements in Release 2 extending the Release 1 capabilities.

5.1 Overall Architecture The TISPAN Release 2 NGN functional architecture is structured according to a service layer and an IP-based transport layer. The service layer comprises the following components:

• the core IP Multimedia Subsystem (IMS);

• the PSTN/ISDN Emulation Subsystem (PES);

• other multimedia subsystems (e.g. IPTV Dedicated Subsystem) and applications;

• common components (i.e. used by several subsystems) such as those required for accessing applications, charging functions, user profile management, security management, routing data bases (e.g. ENUM), etc.

This subsystem-oriented architecture enables the addition of new subsystems over the time to cover new demands and service classes. It also provides the ability to import (and adapt) subsystems defined by other standardization bodies.

The transport layer provides IP connectivity to NGN user equipment, under the control of the network attachment subsystem (NASS) and the resource and admission control subsystem (RACS). These subsystems hide the transport technology used in access and core networks below the IP layer.

ETSI

Draft ETSI WI 00005 V<0.4.8> (2010-04)8

The TISPAN NGN architecture complies with the general reference model for next generation networks defined in ITU-T Recommendation Y.2011 [3] and is therefore layered with a service stratum and a transport stratum. Each of these layers is further decomposed into sub-systems that perform specific roles within the overall architecture. The subsystems are further broken down into functional entities that provide specific functions – and sets of interfaces among these entities.

The major sub-system in NGN Release 2 are:

• the core IP Multimedia Subsystem (Common IMS);

• the PSTN/ISDN Emulation Subsystem (PES);

• other multimedia subsystems (e.g. IPTV IMS-based or Dedicated Subsystems) and applications;

• common components (i.e. used by several subsystems) such as those required for accessing applications, charging functions, user profile management, security management, routing data bases (e.g. ENUM), etc.

This subsystem-oriented architecture enables adding of new subsystems over the time to cover new demands and service classes. It also provides the ability to import (and adapt) subsystems defined by other standardization bodies.

The integration of the Common IMS in the TISPAN NGN architecture is symbol of this approach. The service layer comprises various applications as well as a number of reusable application support functions (user profile servers, routing data bases, etc…) and service control subsystems enabling these applications be delivered. The transport layer comprises a transport control sub layer on top of transport processing functions in the access and core networks. The transport control sub layer is further divided into a Network Attachment Subsystem (NASS) and a Resource and Admission Control Subsystem (RACS).

5.3.1 Characteristics of the Release 2 Functional Architecture

The architecture specified within the framework of TISPAN NGN Release 1 is very stable. Very few modifications and additions were made within the framework of TISPAN NGN Release 2:

• The position of the Access Management Function (AMF) in the overall architecture was modified. The AMF is now seen as a transport processing function rather than a NASS entity. The Access Management Function (AMF) translates network access requests received from the user equipment into a format that can be understood by the NASS.

• Media-awareness and transcoding capabilities were added to the list of elementary functions that a Border Gateway Function (BGF) can perform.

• An explicit modelling of basic transport functions was added. All transport segments comprise one or more basic transport functions (BTF) which contain two elementary transport processing functions: Elementary Forwarding Function (EFF) and Elementary Control Function (ECF). Physical network elements (e.g. a bridge, a router etc.) - typically contain a BTF and might contain additional functional entities, e.g. RCEF. Both unicast and multicast processing are enabled.

• Restrictions on the Resource Control Enforcement Function (RCFE) were removed. RCEF instances can be found in any transport segment and the number of instances per network segment is no longer limited.

• The Layer 2 Termination Function (L2TF) was removed from the transport model. • Within the service layer, the Streaming and Content Broadcasting subsystems were replaced with the IPTV

Dedicated Subsystem. • The Interconnect Border Control Function (IBCF) was removed from the overall architecture, as it is now

incorporated in the core IMS specifications. • Guidelines on the implementation of service oriented and connectivity oriented interconnections were

added. • A high-level decomposition of the user equipment in the form of a customer network was added, in line

with ETSI TISPAN TR 185 004. • Guidelines were added on the implementation of multicast functions.

5.2 NASS The Network Attachment Subsystem (NASS) provides registration at access level and initialization of User Equipment (UE) for accessing to the TISPAN NGN services. The NASS provides network level identification and authentication, manages the IP address space of the Access Network and authenticates access sessions. The NASS also announces the contact point of the TISPAN NGN Service/Applications Subsystems to the UE.

ETSI

Draft ETSI WI 00005 V<0.4.8> (2010-04)9

Network attachment through NASS is based on implicit or explicit user identity and authentication credentials stored in the NASS.

5.3.1 Characteristics of Release 2 NASS

Release 2 adds event notification capabilties to NASS. Application functions can express the desire to get notified in case certain events occur within NASS using the newly introduced event registration information flow. In case an particular event occurs (e.g. a user attaches to the network), those AFs which registered for this event will get informed through the event notification information flow.

NASS Release 2 incorporates several enhancements to the Connectivity Session Location and Repository Function (CLF). NASS Release 2 introduces a reference point between CLF and the CNG configuration function (CNGCF). Using the new reference point, CLF can supply e.g. access network or CNG related information to the CNGCF to support CNG configuration.

The introduction of IPTV with the associated multicast traffic control requirements are also reflected by the enhancements to NASS in Release 2. The NASS User's access profile is complemented with gate setting information for multicast.~~Further on, NASS Release 2 extends NASS' capabilities to flexibly adapt to multiple access network types. NASS Release 2 allows profiles within the Profile Database Function (PDBF) to be sub-divided into sub-profiles, with each sub-profile being associated with one or more logical access identifiers.

Additionally, Release 2 provides a formal documentation of the a2 interface.

5.3 RACS The Resource and Admission Control Subsystem (RACS) is responsible for the implementation of policy-based transport control features, by using procedures and mechanisms that handle resource reservation and admission control for both unicast and multicast traffic in access and core networks.

Besides acting as a Resource Control Framework, RACS also includes support for controlling Network Address Translation (NAT) at the edge of networks and for assisting in remote NAT traversal.

Furthermore, RACS also covers aspects related to the derivation, modification, and installation of traffic policies, end to end quality of service, transport-level charging and overload control.

5.3.1 Characteristics of Release 2 RACS

In this overall context, restrictions applicable to RACS for Release 2 are indicated in the following:

• only single access and single core domains are handled,

• the interconnection between domains is limited to scenarios involving only wholesale and roaming between two domains,

• the multicast topic is limited to scenarios involving only a single domain,

• interconnection in terms of QoS with home networks as well as external NGN or non-NGN networks is not specified,

• the e2e QoS handling is limited to scenarios involving only wholesale and roaming between two domains,

• other QoS handling aspects, e.g. QoS monitoring and QoS reporting, as well as scenarios for the metro segment, are covered only in an informative annex.

5.3.2 RACS Enhancements to Release 1

Regarding enhancements to RACS for Release 1, the main add-ons provided by RACS for the current release are listed below:

• refinement of the basic architecture with the definition of reference points for external interconnection as well as for interconnection with the last mile in the access segment,

ETSI

Draft ETSI WI 00005 V<0.4.8> (2010-04)10

• modelling of the basic architecture and of the text of associated Functional Elements in an agnostic way in terms of transport technology, i.e., not so xDSL-oriented as in Release 1,

• definition and handling of the impact of business roles in the basic architecture and its impact on deployment scenarios,

• communication between different administrative NGN domains,

• scheduling of resource reservations,

• handling of security requirements,

• handling of the QoS Pull mechanism in addition to the QoS Push mechanism, in order to enable multicast.

Within Release 2 the feasibility of unsolicited communication in the NGN (ETSI TR 187 009) was analyzed to determine if UC is a risk to the NGN user or to the NGN. The study offers justification for UC countermeasures by presenting the results of a Threat Vulnerability and Risk Analysis (TVRA) that quantifies the likelihood and impact of UC in the

Editors Note:[7]: Additional text based on deliverables DTS/TISPAN-01042-NGN-R2 (TS 181 014), DTS/TISPAN-01044-NGN-R2 (TS 181 016), DTS/TISPAN-02048-NGN (TS 182 027), DTS/TISPAN-02049-NGN (TS 182 028) is required. The two approaches also need to be briefly summarised. Contributions welcome.

One of the most important services introduced in Release 2 is IPTV. The goal of introducing IPTV is to enable IPTV services within the NGN, especially focusing on the integration of IPTV services with the other communication services and capabilities defined in TISPAN.

There are two approaches of IPTV in Release 2, one specifying the architecture and functions of an IPTV system by utilizing the Common IMS architecture and its associated features and services; i.e. the IMS-based IPTV subsystem, as defined in DTS/TISPAN-02048-NGN (TS 182 027). The second approach is the integration of IPTV functions into the NGN architecture; i.e. the Dedicated IPTV subsystem, as defined in DTS/TISPAN-02049-NGN (TS 182 028).

Services provided by both IPTV subsystems in Release 2 are similar, and include both Broadcast TV service (with or without trick modes), Content on Demand (CoD), and network Personal Video Recording (nPVR).

6.2.1.1 Common architectures of the two subsystems.

The Media Control Function (MCF) from NGN dedicated IPTV subsystem (ETSI TS 182 028) provide similar functionalities as MCF from IMS based IPTV architecture (ETSI TS 182 027) and also media delivery function (MDF) in both architectures provide similar functionalities.

The reference point Xp between MCF and MDF is used for the similar purposes in both IPTV architectures of TISPAN Release 2 (in NGN dedicated IPTV subsystem and also in IMS based IPTV) as well as both reference points between MCF/MDF and UE (Xc for media control and Xd for media delivery).

6.2.2 IPTV - IMS-based Subsystem

ETSI TS 182 027 specifies an architecture and functions of an IPTV system that makes use of the NGN IMS architecture and its features, implementing the IPTV requirements defined in TS 181 014 [14] and TS 181 016 [15].

This approach draws upon the NGN IMS support for AAA, QoS and Multimedia Sessions by adding IPTV specific components to the architecture:

• Service Discovery and Selection Functionality for UEs to discover IPTV services offered, providing users a listing of offered services and content. This funcitonality is hosted in the SDF and SSF entities. While the SDF is a SIP Application Server, the SSF is a stand alone functional entity delivering the Service Selection Information to the UE over Xa in multicast or unicast.

• An IPTV Service Control Function (SCF) that hosts IPTV service logic and can be specialized depending on the type of IPTV service. The SCF is a SIP Application Server. A new SIP reference point towards the MCF was introduced for the SCF to contact the MCF in the session setup phase

• MCF and MDF entities for Media Control and Delivery as mentioned in clause 6.2.1. This is achieved over reference points Xc for Media Control signalling and Xd for Media Delivery.

In addition, an IPTV service relevant IPTV User Profile structure was defined, e.g. for subscription settings. Using the NGN core IMS as underlying architecture, the IPTV User Profile relates to the IMS Public User Identity and can be stored in the UPSF, the IPTV Application Server or a standalone XDMS entity.

Editors Note: [9] Clause 6.3.1 is edited from 20wTD084

6.3.1 Security Capabilities

IPTV is one of the core subsystems that have been added for Release 2. IPTV is a multimedia service of importance for a number of network operators and vendors expected to be a major revenue enhancing addition to the NGN for Release 2. IPTV have introduced several new interfaces, as well as extended the service and security capabilities of release 1 interfaces. In particular there are the Xc interface for media control and the Xd interface for media delivery.

There are many security challenges associated with IPTV and these can generally be categories into: IP layer security capabilities, network layer security capabilities, service layer security, media security, service availability, identity management (users, devices, sessions, services), unsolicited communication, lawful interception, and authorization. Focus has been on most of these security challenges. Particular focus has been put on security of media and the principles of secure handling of content (in contrast to content protection mechanisms such as DRM). Media security is discussed in ETSI TR 187 007; Feasibility study on Media Security in TISPAN NGN.

6.3.1.1 Security Activites for Release 2

For Release 2, a Threat, Vulnerability and Risk Assessment analysis (TVRA) for IPTV was carried out with the aim to review and extend NGN Release 1 with IPTV security requirements and to specify IPTV security capabilities for NGN Release 2. The TVRA did not analyse any specific content protection mechanism (such as DRM), and merely specified required properties of those mechanisms. The overall security properties needed are: (i) The NGN R2 IPTV service should support a means to ensure that the content once delivered is being managed (saved, stored, viewed, re-viewed etc.) only by authorised entities. (ii) The NGN R2 IPTV service should offer the user a means to control and restrict access to specific IPTV content. These two overall security property statements resulted in 13 content specific security requirements.

For Release 2, there are 46 IPTV security requirements, where 19 are common IPTV security requirements, 13 are content specific requirements, 9 are network and service specific requirements, and 3 are availability specific requirements. The security requirements are specified in ETSI TS 187 001. The security requirements were also checked against the security features of other relevant standardization bodies including ATIS, OMA and ITU-T.

6.3.1.2 IPTV Security in Release 2

To ensure soundness and completeness of the IPTV security requirements, a number of security objectives were identified. These objectives describe overall security needs for IPTV and are directly linked to the IPTV service requirements and capabilities as described in ETSI TS 181 014 and ETSI TS 181 016. In addition, the IPTV relevant service requirements and security capabilities for release 1 was taken into consideration when specifying the Release 2 security needs (security objectives) for IPTV.

The IPTV security objectives are defined in ETSI TS 187 002, and the IPTV security requirements are defined in ETSI TS 187 001. Some work on the feasibility of enhancement of the NGN security architecture for IPTV are documented in 187 003 (informational appendix). The IPTV security capabilities defined for Release 2 are IPTV content and media protection, non-forgeable identification, authentication and authorization of IPTV end-users, IPTV services and

providers, IPTV devices and IPTV sessions, and integrity and availability protection. In addition, device, user and session identities must be linked together to prevent unauthorized use of IPTV services, as well as IP session hijacking.

• Enhance the present management architecture to cover Release 2 requirements, and develop a specific TISPAN information model and specific TISPAN Management interfaces to cover the needs OF NASS, RACS and IMS for functions in 2, 3 and 4 above.. This work should of course be carried out in close co-operation with TMF (SID and MTOP teams in particular). <WG8 specific>

A work area is a collection of related topics. A WI can be mapped to a set of topics or to a single one. A topic may be realised by more than one work item (e.g. the stage 1, 2 and 3).

In general, within a work area a stage 1-stage2-stage3 workflow should be implemented.

In this section a set of work areas is preliminarily identified together with the related topics.

The topics here listed are a combination of:

• R1 completion

• R2 enhancements

• R2 new services and capabilities

The “R1 Completion” and “R2 enhancements” topics are explicitly indicated. All the others are to be considered as “R2 new services and capabilities”

Note: there are some issues listed above that are natively within the scope of WG7 and WG8. It is not clear if it is necessary to have a Security Work Area and a Management Work Area, or to leave the work to those WGs.

Note: the Work Areas are listed WITHOUT any order.

Editors Note: Do not include R1 Essential work items.

Editors Note: TISPAN Working Methods (TR 181 017) is not included as it is not an NGN technical deliverable.

A.1 IMS evolution The Work Items to support this work area are shown in Table 1.

2 This refers to services that may rely upon 1-to-n group communication schemes, such as push services, and IPsec capabilities also need to be taken into account.
