Access Technology

This Group was recently set up to look at the technology being deployed in the access network to determine whether there are any standards required to help the customer/provider experience.

All IP Task Group

This Task Group is responsible for all technical telephony aspects associated with the implementation of voice services over UK IP networks.

To support end to end customer connections, services and interconnects between Communication Providers, NICC is developing new (and enhancing existing) standards to support new network and access technologies.

The impacts of a migration to IP for industry sectors making use of the current voice network for data transmission are being tested and reviewed. Guidance is being documented for these service sectors.

The Group is updating existing end to end network performance standards to support the new All IP network and access environment.

The Group is developing new architecture standards to support telephony over IP networks.

SIP Task Group

This Task Group is responsible for developing NICC standards for any matter concerning the use and interworking of signalling protocols over the UK telecommunication networks.

The scope of the Task Group covers the user to network interface and the network to network interface.

Currently, specific standards are being developed include the interworking UK ISUP to SIP and developing a SIP Implementers’ guide.

Emergency Location Task Group

Emergency Location

NICC has influenced the development of the ETSI M493 architecture, specifying the way to locate nomadic VoIP emergency callers.  NICC is now developing a report that will demonstrate the impact this architecture will have on UK CPs and Internet Service Providers.

Emergency Call Architecture

NICC is producing a document that shows the way in which emergency calls need to be supported across SIP networks, specifically around how location information will be carried in SIP networks and the resilience these calls required.

Both the above work areas will significantly impact on the way emergency calls are dealt with and managed in the UK by all communications providers.

Nuisance Call and CLI Task Group

This NICC Task Group is the UK Technical Forum to discuss the reduction of nuisance calls in the UK.

This NICC Task Group is looking at the various aspects and the development of standards for the implementation of STIR in the UK.



Security Task Group

This Task Group is responsible for providing information that helps to ensure the security of the UK telecommunications network.

Recently, the Group has developed a Security Guidelines to mitigate the risks to networks introduced by the migration to IP technology across communication networks.

Currently, the Group is developing a new set of standards that will provide general guidance for telecommunication networks and will document any requirement for networks resulting from the (Telecommunication) Security Bill 2021.

Task Groups in abeyance or closed

IP Routeing Task Group

This TG is currently in abeyance having produced ND1524, a report proposing a method for a more efficient routeing of IP calls between UK Network operators.

Blockchain Task Group

The TG was run by Ofcom, looking at the Proof of Concept of using Distributed Ledger Technology for Number Portability in the UK. This TG is now closed and has concluded that Blockchain is unsuitable for use with NP.

DSL Task Group

The TG is currently in abeyance having updated the UK Access Network Frequency Plan.

SIP Overload Control Task Group

The agreed method for SIP Overload Control for Network to Network Interface is now published in ND1653
