Number portability is a facility that enables subscribers, who so request, to be able to retain their telephone number(s) when they change from one provider to another provider.
There are a number of consumer benefits associated with number portability. Number portability facilitates consumer choice and effective competition by allowing consumers to retain their telephone number when they switch provider. This makes switching a more attractive proposition as consumers may be reluctant to switch if they have to go through the inconvenience and possible expense of changing their telephone number.
This objective, to make it easy and swift for consumers to switch provider, is central to Ofcom’s proposals in relation to port lead times. Ofcom considers that excessively long port lead times may discourage consumers from switching provider, which in turn may have an adverse impact on competition between providers.
In relation to the routing of calls to ported numbers, Ofcom’s key objectives concern the protection of consumers against network failure and ensuring the efficient use of networks. Ofcom recognises that in respect of the existing routing system for mobile ported numbers there may also be a misalignment of incentives for operators to port numbers.
Ofcom is considering the implementation of number portability in the context of the development of Next Generation Networks (“NGNs”) in the UK and in relation to mobile networks. BT has announced its 21CN plans, which set out to replace progressively its core network with an architecture based on NGN technology. Many other network operators are either planning or have begun implementation of networks based on NGN designs.
Ofcom is also using the opportunity of this consultation to consider and review the issue of mobile port lead times. Ofcom is considering whether the current industry agreed five day process should be reduced to a shorter period.
