Mobile IP Proxy
First Claim
1. An infrastructure device for use in an intermediate network in a telecommunication network for controlling communication traffic in the intermediate network, the infra structure device acting as a Mobile IP proxy for communication between a home network and a visiting node, wherein the infrastructure device is arranged forsending as temporary home agent address an Internet Protocol (IP) address of the device in the intermediated network between the home agent network and via an access network to a visiting node connected to the access network;
- setting a home agent address for the visiting node in the device to an address of an actual home agent address; and
relay user plane traffic through the device between the visiting node and the home agent.

Abstract
The present invention relates to a device, method, system, and program for facilitating the control in an intermediate telecommunications network (202) of user plane traffic between a visiting node (209, 210), attached to an access network (203), and a home network (201). The intermediate network includes a mobile IP proxy (207) for acting as home agent for the mobile node and relaying user plane packets between the home network and visiting node.

7. A method for controlling traffic flows in a telecommunications network, comprising the steps of:
-
sending as temporary home agent address an Internet Protocol (IP), address of a mobile IP proxy in an intermediate network between a home agent network and an access network to a visiting node connected to the access network; setting a home agent address for the visiting node in the Mobile IP proxy to an address of an actual home agent address; and relaying user plane traffic through the mobile IP proxy between the visiting node and the home agent; - View Dependent Claims (8, 9, 10, 11)
