Abstract

The present invention provides a system, apparatus and method wherein the network initiates a PDP context activation for a second PDP context using a new IP address that can be used for new transport sessions whenever one or more operator configured criteria apply. For example, the present invention can be used to: (1) route ongoing and new communication sessions from the old network device associated with the old IP address through a new network device associated with the new IP address using the old IP address; (2) route ongoing communication sessions from the old network device through the new network device using the old IP address, and new communication sessions directly through the new network device; or (3) route ongoing communication sessions from the old network device through the new network device without using the new IP address, and new communication sessions directly through the new network device.
