SYSTEM AND METHOD FOR PROVIDING NETWORK ADDRESS TRANSLATION CONTROL IN A NETWORK ENVIRONMENT
First Claim
1. A method, comprising:
- receiving packets at a network element for a communications flow from an end user, the network element receiving the packets if the flow is initiated through a wireless network and through a wireline network, wherein a network address translation (NAT) binding occurs for the end user at the network element, the NAT binding including an Internet Protocol (IP) address for the end user.

Abstract
A method is provided in one example embodiment and includes receiving packets at a network element for a communications flow from an end user, the network element receiving the packets if the flow is initiated through a wireless network and through a wireline network. A network address translation (NAT) binding occurs for the end user at the network element, the NAT binding including an Internet Protocol (IP) address for the end user, the NAT binding being controlled by policy infrastructure coupled to the network element. The network element can be provided along a routing path for the flow (e.g., the IP session), irrespective of whether mobility services are used by the end user. The policy infrastructure can also support NAT control between home and visited networks with the visited network retaining control and privacy over the actual NAT elements being used.
