Title:
A METHOD FOR SELECTING A GATEWAY OF THE RADIO NETWORK
Document Type and Number:
WIPO Patent Application WO/2009/043210
Kind Code:
A1
Abstract:
A method for selecting a gateway of the radio network includes: if 3GPP AAA Server
successfully performs an authentication for UE, then Home 3GPP AAA Server determines
the selecting function information parameter and determines whether UE accesses
3GPP network through the visited PDG, and sends the returning back message to
the visited 3GPP AAA Proxy; if the returning back message does not carry the indication
parameter not allowing UE to access 3GPP network through the visited PDG, then
the visited 3GPP AAA Proxy ignores the selecting function information parameter
and forwards the returning back message to the visited PDG; finally, the visited
PDG authorizes UE to access the network. When 3GPP Evolved network is Home network,
and 3GPP network of the pre-Evolved network is the visited network, the present
invention solves the problem for selecting the gateway when UE accesses the network
through non-trusting and non-3GPP IP access network.
