System and method for supporting the transfer of data packets from the Internet when a mobile node roams from a home network to a visited network

摘要

A telecommunications system operable to provide a session mobile communications to a mobile node using an internet protocol, comprising: a proprietary network packet data operable to communicate internet packets to and from the mobile node to provide the communications session, when the mobile node is affiliated to the home network packet data, including own network packet data own agent of the mobile node and a visited network packet data operable to communicating internet packets to and from the mobile node to provide the communications session, when the mobile node is affiliated with the visited network packet data, where from the home network packet data and the visited network data packet includes a packet data gateway for controlling communication of internet packets to and from the network pro pia packet data to and from the visited network packet data, and after receiving an Internet package update link that provides an address by the mobile node after a change of affiliation from the home network packet data to the visited packet data network gateway packet data and own agent operable to set a path for Internet packets between the home agent and the mobile node through the gateway packet data, allowing the gateway packet data control the communication of internet packets from the home network packet data to the mobile node and the communication of the internet packets received from the mobile node via the visited network packet data when the mobile node is affiliated with the visited packet data network.
