Contents Attractions and importance of ENUM Requirements issued A possible resolution Advantages comparing to using “e164.arpa” Current situation for this possibility

Attractions and importance of ENUM – Enables to use a single E164 number to access different applications –Accessed from both circuit switching network and IP based network (including Internet) –Promote the convergence of PSTN and IP –Act as an important role in the next generation network –Bring great impact to the traditional telecommunication network

Requirements issued Correct use and effective management of E.164 numbering resource Quality of Services provided through ENUM should be ensured

A possible solution To establish a new TLD(e.g. e164) special for ENUM implementation and make an international, neutral and fair organization (e.g. ITU-T) to administer the new TLD.

Advantages comparing to using “e164.arpa” Reduce one level of address resolution and speed up the resolution –No consensus about it Promote the rationalization of traffic distribution in Internet Be propitious to establish a more logical management mechanism

Current situation for this possibility No consensus A correspondence group has been established to develop a document on the information required to request a new TLD. The related work is going on.
