Description / Abstract:


This report defines, describes, and provides an evaluation of the concept of Unassigned Number Porting (UNP) by the industry in response to FCC 00-104, paragraph 231 and resolves INC Issues 177 and 222.

This report provides a current definition of the UNP concept, a history of UNP activity, a set of UNP assumptions and constraints, and a set of UNP principles. It also provides comments on the UNP concept from both the supporters and opponents of UNP.

An open issue regarding the implementation of UNP is whether or not a third party administrator is necessary. This report describes three alternatives:

UNP without an administrator,

UNP with a minimal administrative structure, or

UNP with an administrator
