Abstract
A method and system for enabling a mobile station (MS) to transfer from one Network Address Translation (NAT) domain to another NAT domain. Dynamic rules created in the first NAT domain are transferred to the second NAT domain via a first Media Policy Routing function. A tunnel is created between the second NAT domain and the first MPR for transferring a MS session. A new session from the MS is created outside the tunnel and once the MS session times out, the MS session, the states existing in the first MPR and the second NAT domain utilizing a new set of dynamic NAT rules created in the second NAT domain are all removed. The tunnel is then removed and communication via a second MPR and the second NAT domain is available.
