External Relations (1/3)

TISPAN considers co-operation with external bodies and organisations as essential.

TISPAN provides and receives input with many other bodies. Interest of external bodies in TISPAN is demonstrated by:

Active delegations from many regions (Europe, China, Japan, North and South America, South Africa).

Per meeting, about 150-200 delegates and over 300-400 documents.

TISPAN has adopted a positive outlook and ethos of enhancing and developing co-operation with any interested organisation.

Development of Global specifications and a global message.

TISPAN_NGN Release 2

18

Synchronisation of Specifications with 3GPP

Alignment of the timescales and dependencies of TISPAN R1 with the work in 3GPP Release 7 on FBI.

Alignment of the timescales of TISPAN R2 with the ongoing work in 3GPP Release 8 and FMC.

Objective: Single core solution based on: IMS Core signalling technology Multiple access technologies in cooperation with 3GPP

• ADSL• WLAN via xSDL• 3GPP CAN (GPRS, WLAN via GPRS, etc..).

Ongoing discussions within TISPAN, 3GPP and other SDOs and groups.

19

Services and Features (1/2)

TISPAN is progressing the work on R2 concerning the following main new work items: Requirements analysis for FMC. Requirements analysis for home networking (in cooperation

with e.g. HGI).   Requirements for network capabilities to support IPTV services

(in cooperation with e.g. ATIS IIF and DVB). IPTV Integration of NGN Services and Capabilities using IMS Support of Business Services and Enterprise Network inter-

working. Close and direct co-operation with Ecma International on

NGN Business services and Enterprise capabilities. NGCN – NGCorporateN interconnect requirements.

20

Services and Features (2/2)

According to the TISPAN enhancements for R2 and beyond; new requirements in the NGN R2 definition were raised, on requirements analysis for work that needs to be shared with other bodies. Requirements for originating and terminating party

multimedia information presentation and restriction.

Additional Features for Enhanced Communication Diversion  (these features are still under discussion)

Service Requirements and Network Capabilities for Release 2. 

Release 2 Definition.

21

FMC – Fixed Mobile Convergence

A work-item on requirements collection has been started Collection of about 10 use cases regarding FMC The Use Cases are only there to derive and analyse

requirements The objective of the WI is to identify (high level)

requirements This includes identifying in which SDO's / body's / group's

have the scope that the requirements exist TISPAN wishes to co-operate on FMC; i.e. based on a

common set of requirements To agree an appropriate distribution of work.

22

Release 2 - ArchitectureNew Functionalities (in progress)

Evolution of RACS Resource control in the core Towards End-to-end QoS

Evolution of NASS Additional access technologies

• Fixed access via xDSL (e.g. ADSL)• wLAN via xDSL (e.g. IEEE802.11)• WiMAX etc..

IPTV support Online Charging Overload control (GOCAP)

23

Overview of New WorkNumbering, Naming, Addressing, Routeing

Active discussions with GSMA IREG (Interworking Roaming Expert Group) Infrastructure ENUM GSMA IPX backbone (IP eXchange – next generation of

GPRS Roaming Exchange)

Identification of key management and operational issues to be considered for a shared approach to be viable

It is expected that key interconnect issues will also come to the fore.

Objective: to specify a Single global solution for NGN

24

Overview on New WorkSecurity, Testing, Network Management

Security Joint meeting with 3GPP SA3 on authentication and NAT/FW

(network address translation, firewall) transversal issues. Authentication to NASS and to IMS services

Testing Conformance to TISPAN, 3GPP, ITU-T standardised protocols Global interoperability of PES and Core IMS NGN R1

Network Management Service Oriented Architecture (SOA) NGN OSS (Operation Support System) Service interfaces in line

with NGN OSS architecture. Common information model TISPAN MIM

• Subscription Management• Network Resource Management

Network resource management based on 3GPP model both reuse + new TISPAN-specific entities

25

QoS

The TISPAN System Group will have overall control of QoS issues within TISPAN and will coordinate and allocate work to the Working Groups as necessary.

TISPAN and STQ will work in close co-operation. STQ works on what we want to achieve in terms of

parameters and numbers User-to-user and application layer QoS requirements The network performance required to support these

requirements TISPAN works on how we achieve this in terms of design

Functional and architectural requirements Signalling and protocols to be implemented

Co-operation with other bodies as well, e.g. ITU-T, IETF etc., see also “External Relations” at the beginning of the presentation.

26

Security Considerations

Regarding security, focus on requirements covering the following considerations: Security

• Network security

• User security

• Security management Regulatory aspects

• Lawful Interception

• Data privacy

• Data retention TISPAN WG7 are to make recommendations on Services

features, architectures, and protocols

27

Home Devices and Home Networking

The Terms of Reference for TISPAN have been enhanced to include home devices and home networking issues, considering layer 2 and higher layers.

Regarding the layer 2 issues, TISPAN will have the ownership of the layer 2 related to the NGN home devices and networks and will closely coordinate with TC AT/TM. AT/TM will keep the ownership of layer 1.

28

Summary

29

Summary

Thanks to all TISPAN collaborators and officials! Identification of the right issues in order to cover

the market needs. Provision of high quality and implementable

deliverables. Maxim: To Achieve Maximum Co-operation and

Communication, Internally and Externally. Globalisation of our results.
