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. In Ofcom's view the shorter the process, the better it is for competition and consumers. Therefore Ofcom is proposing to reduce mobile port lead times to a period of less than one working day. However, if Ofcom receives evidence that shows that the costs involved in moving to a lead time shorter than one working day outweigh the benefits then Ofcom will need to consider whether a three working day period is more appropriate in light of the evidence received. It would currently appear that the current mobile porting process can be reduced to three working days without the mobile operators incurring significant costs.
