No comments had been received on the September minutes and these were accepted by the Exec

The updated actions are covered at the end of this document. During the discussion of the actions Peter Ryde was requested to obtain details of the dead line for responses to the questions raised by Ofcom to support its cost modelling.

Action 1 – 25/10/2007 – Peter Ryde to circulate details of the dead line for a response to Gideon Sensensieb regarding the questions circulated to the CPs to support Ofcom’s cost modelling work.

To top

A straw man developed for capacity based charging by Ellare & Oxera has been circulated to Members for comment. To date only BT has commented. The Exec was requested to encourage feedback from their representatives.

A template to collate member views on a usage framework has been circulated to the Commercial work group. To date only BT and Thus have responded which is disappointing given this should be the framework option best understood by CPs. Again the Exec was requested to encourage feedback from their representatives.

Ellare / Oxare have been appointed to analyse feedback from members against an agreed template to compare member views of the three framework options ( Capacity, Usage and Ports).  This will be presented to the commercial work group for comment on 30^th October. CPs will subsequently be asked to weight the feedback to give a prioritised view of the options. This will be discussed a commercial work group meeting on 15^th November so that a final paper and recommendation can be made in time for the November Executive. At this time it would appear that the majority of members will support a usage based scheme but with a significant minority interested in a capacity option.

Awaiting meeting with UKCTA on 29^th October

Definitions

Awaiting meeting with UKCTA on 29^th October

Charging

Billing and Payment Processes

Awaiting meeting with NICC B2B on 1^st November

Telephony Emulation

No actions on NGNuk

Numbering and Addressing

Awaiting Exec feedback on principles ( Action 8 – 27/09/2007). It was agreed that Peter Ryde would collate responses as they are received and circulate these for additional comments . The aim is to discuss this fully at the November Exec.

Quality of Service

At our meeting  the meeting between NGNuk and NICC in July it was agreed that the NGNuk PID format which follows Prince2 methodology would be used as the approach for handover. To test this we submitted a PID relating to QoS classes by NGNuk to NICC. Paul Rosbotham has confirmed the format is acceptable and that Dave Mustill (BT) would respond on the content shortly.

As the initial commercial framework is voice only it will have only 1 QoS class, as such any response does not affect the current work stack but will need to be captured when ( and whoever) has to deal with a framework to cover all services.

Network (and Transport) Layer

No action on NGNuk

Control ( and Intelligence) Layer

The Exec agreed that NICC is to lead however there is likely to need for significant NGNuk input as policy options related to presence, security and authentication emerge.  See work streams below.

Data (Ethernet)

The final draft is with members for comment. This closes for comment at the end October although no further comments are anticipated. The final draft was also copied to NICC for information.

Planning and Operations

Awaiting meeting with NICC B2B on 1^st November

Service Level Agreement

Awaiting Exec feedback on principles ( Action 6 – 27/09/2007). It was agreed that Peter Ryde would collate responses as they are received and circulate these for additional comments . The aim is to discuss this fully at the November Exec.

To top

NGNuk has received input from BT only on the Interconnect Requirements we passed to NICC for comment.

Peter Ryde discussed with Paul Rosbotham how practical or beneficial it would be to take further feedback and then update our Requirements since (a) if the Orange release relates to BICC voice then the NGNuk requirements may be superseded before they can be implemented into future standards work by NICC/TSG and (b) that evidence to date suggests that CPs will not support an extensive work programme to respond to a broad set of issues and queries raised by NICC/TSG. Peter Ryde expressed the view is that NGNuk should respond to a lead from NICC on those areas where a commercial steer on standards would be of value ( i.e. where there are more than on technical option that could be implemented) . Such areas would be Security and Authentication, Presence and Location etc.

Real Time Voice

The Voice PID outlines the purpose of the work stream as “developing a specification for Real Time Voice (PSTN/ISDN) reference offer for interconnected NGNs with a major deliverable as “one or more technical interconnect specifications to support the agreed reference services”.

Given the resourcing of current NGNuk work streams to date it was agreed that CPs were unlikely to be able to support this activity (due to both the availability and prioritisation of resources).

It was felt that whilst this work will need to be undertaken it is unlikely to have sufficient impetus until such time as interconnection with BT 21CN becomes imminent.

The topic had been discussed briefly at the August Executive meeting and Action 1 – 30/08/2007 – requested that the Secretariat suggest a form of words which the Exec could endorse agreeing the approach. The following was proposed:

The members of NGNuk understand that to facilitate CP to CP interconnection a significant level of detailed work will be required both technically and commercially. It is further recognised that considerable resources are being deployed on Voice interconnect through industry support of Consult 21 process  with BTW. To avoid unnecessary duplication and to avoid potential confusion the members of NGNuk have agreed that other than the commercial framework itself,  further work on Voice within NGNuk will be suspended pending progress between industry and BTW via Consult 21. It is anticipated that CP to CP interconnection will subsequently build upon some agreed subset of those agreements,  principles, service descriptions etc that are agreed between industry and BT through Consult 21.

Action 11 – 27/10/2007 – was that Peter Ryde was to distribute the proposed wording on the approach to Real Time Voice to the Executive for comment. 3 comments from the Exec were received.

These were discussed by the Executive and the above wording agreed as representing the Executive position on activity relating to Real Time Voice.

Data

Data Interconnect Requirements V3.2 has been agreed by the working group to reflect the VPN requirements articulated during MPLS debate. The final draft is with Members for comment.

This will be sent to NICC imminently, however it the input is unlikely to be utilised prior to the Orange release.

Numbering and Addressing

The Exec members are to provide their thoughts to the Secretariat regarding the key aims and attributes of the principles that need to be considered for Numbering and Addressing. These will be collated by the secretariat and represented for discussion at the November Executive meeting.

Presence and Location

BTW have provided lead (Ryan Hardy) who has drafted a paper provided to the Secretariat for comment. This was circulated to members for comment by the end October. No comments have been received although a number have been promised. Peter Ryde agreed to circulate details to The Executive of who had stated they intended to respond. Non respondents were requested to submit a response.

Action 2 – 25/10/2007 – Peter Ryde to inform the Exec of those CPs who had stated they intended to submit a response to the Straw man on Presence and Location

Security and Authentication

The next work group review is not anticipated prior to November, however a meeting is scheduled with Jim Credland (Thus) who is leading the work group on 25^th October to review the status.

PWC were to present on their NGN cost model however this will be deferred to the December meeting

Payment – Peter Black expressed concern at the continued difficulties in obtaining payment of membership fees from some members.

Action 10 - 27/09/2007 – Secretariat to follow up with NICC to obtain collective response from NICC regarding the Requirements submitted by NGNuk. A call took place between Peter Ryde (NGNuk) and Paul Rothbotham (NICC) on 24th October and a follow up meeting is being arranged with members of TSG for 8th November to cover: Data Requirements – covered above QoS -  covered above Orange Release - When NGNuk met with NICC in July there was discussion on the need for input for the Orange release towards the end of the year. It was suggested that the approach NICC might need to implement was to articulate the implications of the technology choices as the first stage and then seek commercial/product views on these. TSG have their first requirements capture for Orange setup for the 11th December which NGNuk will attend. It is likely that the Orange Release will need to address BICC voice which is a requirement (similar to SIP) for the mobile operators (it supports a release of the 3GPP standards which will be required by the mobiles for an interim period until they upgrade to SIP). Consequently, it could be Orange may therefore be a limited release with a subsequent release following rapidly behind. Clearly if this occurs NGNuk may no longer exist when commercial input is required for whichever release follows. A discussion took place regarding the question of how this was omitted from the MO inputs to the NGNuk requirements work  and also the governance issue of how this prioritisation was established. Measurement – covered above Interconnect Requirements –covered above NGN Contract Framework – to be discussed at the meeting of 8th November General Update - to be discussed at the meeting of 8th November	Secretariat Ongoing
Action 11 – 27/10/2007 – Peter Ryde to distribute the proposed wording on the approach to Real Time Voice to the Executive for comment . See notes for Programme Update above	Peter Ryde Completed

A paper was circulated to the Exec covering the background and options for the future if NGNuk. This was to solicit thoughts, comments and ideas rather than to propose a recommendation. The Exec were requested to send in any further comments on the paper by mid November. The topic will be discussed fully at the NGNuk Exec meeting in November	Peter Black Steve Unger Completed
