Method and system for establishing a connection via an access network
First Claim
1. A method of establishing a connection via an access network (30) communicating with at least one user terminal, and at least one backbone network (100) comprising at least user terminal authentication and authorization means (50) and at least one user data processing node (60, 62), said method comprising the steps of:
- a) authenticating the connection of a user terminal (10) via said access network (30);
b) selecting one (60) of said at least one user data processing nodes (60, 62) in said authentication step;
c) signaling tunnel parameter information of said selected user data processing node to said access network (30); and
d) creating a tunnel connection between said access network (30) and said selected user data processing node (60) based on said tunnel parameter information.

Abstract
The present invention relates to a method and system for establishing a connection via an access network (30) communicating with at least one user terminal, and at least one backbone network (100) comprising at least user terminal authentication and authorization means (50) and at least one user data processing node (60, 62), wherein the connection of a user terminal (10) is authenticated to the access network (30) and one of the at least one user data processing nodes (60, 62) is selected based on a selection information transferred in the authentication signaling. Then, a tunnel parameter information of the selected user data processing node is signaled to the access network (30) and a tunnel connection is created between the access network (30) and the selected user data processing node (60) based on the tunnel parameter information. By creating a tunnel connection based on a network signaling with both endpoints of the tunnel, the tunnel connection can be created between two network elements originally unknown to each other. Thus, cellular packet-switched services can be accessed over access networks which do not provide a context activation procedure or corresponding control plane signaling function.
