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.

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.
