<p>A method and system for supporting Internet Protocol (IP) services initiated through a public network (101), the services directed to a mobile device (117) through a private network (105) is disclosed. In operation these steps occur: assigning a long lived IP address (113) and user name (115) to the mobile in a wireless network; providing a server (111) including a database that cross references the user name and long lived IP address; connecting an address space for the private network to the public network using network address translator (NAT) (107); initiating a push session between a push client (103) and the mobile by forwarding from the push client to the server the user name; retrieving and returning to the NAT the long lived IP address corresponding to the user name; and assigning a corresponding dynamic public address, using an ALG (109) that is associated with the NAT and returning the dynamic public address to the push client.</p> |
