17
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.
18
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

 Close and direct co-operation with Ecma International on
 NGN Business services and Enterprise capabilities.
 NGCN – NGCorporateN interconnect requirements.
19
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.
20
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.
21
Release 2 - Architecture

• Network Resource Management
 Network resource management based on 3GPP model both
reuse + new TISPAN-specific entities
24
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.
25
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
26
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.
27
Summary
28
Summary
 Thanks to all TISPAN collaborators and officials!
