Abstract

A method and system is disclosed for enabling number portability in a communication session between a caller and a callee in an IMS network. When a caller or callee changes her subscription from a first network to a second network, mechanisms are implemented to have the number portability information provided so that the moved caller or callee can still engage in communication sessions using her original public identification number.
