The main NICC activities include –
Recently set up to look at 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
NICC is developing new and updating existing standards to support the new All IP network and access environment, including end to end SIP sessions.
NICC is reviewing ND1431 (Guidance on CPE Compatibility on NGNs and NGAs) and ND1704 (End to End Network Performance Rules and Objectives for the Interconnect of NGNs) with the aim of writing equivalent standards for the new All IP service.
As a consequence of changes in the physical characteristics of All IP calls routed over Voice over BroadBand solutions (e.g. different levels of Packet Loss. Jitter & Delay) as compared to those of the PSTN, there has furthermore been ALL IP TG associated Regulatory and Industry (BSIA) engagement, e.g. as a prelude to scheduled related testing.
This activity is likely to impact on all services and 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
NICC has influenced the development of the ETSI M493 architecture to locate nomadic VoIP emergency calls and is now progressing 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 in SIP networks, specifically around how location information will be carried in SIP networks and resilience provided.
Both the above work areas will significantly impact on the way emergency calls are dealt with and managed by CPs and ISPs in the UK.
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 standard to mitigate the risks to networks introduced by the implementation of new technology across the network.
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.
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 ANFP.
SIP Overload Control Task Group
The agreed method for SIP Overload Control for Network to Network Interface is now published in ND1653
