Method of controlling packet data traffic
First Claim
1. A method of controlling packet data traffic of a General Packet Radio Service (GPRS) packet service in a communication network, where in accordance with said packet service a communication with a given packet service terminal involves a terminal serving entity supporting said packet service and arranged for performing access control with respect to said given packet service terminal, and a gateway entity supporting said packet service and arranged for providing interworking with other networks, said method comprising:
- setting up a communication between a terminal serving entity of said communication network and a visiting packet service terminal visiting said communication network, wherein said terminal serving entity is a Serving GPRS Support Node (SGSN),tunneling packet data traffic of said visiting packet service terminal from said terminal serving entity of said communication network to a decision entity in said communication network, said decision entity performing a decision procedure for deciding whether the decision entity tunnels said packet data traffic to a gateway entity of said communication network to process said packet data traffic in said gateway entity of said communication network, or tunnels said packet data traffic on to a home communication network of said visiting packet service terminal, the decision entity being arranged to perform the decision procedure for packet data traffic received from a plurality of different terminal serving entities of the communication network.

Abstract
The application relates to a method of controlling packet data traffic of a packet service in a communication network 10, where in accordance with the packet service a communication with a terminal 12 involves a terminal serving entity 101 and a gateway entity 102. Furthermore, a decision entity 103 is provided for performing a decision procedure for deciding whether to process packet data traffic from the terminal 12 in the gateway entity 102 of the network 10, or to tunnel the traffic on to a home communication network 13 of the visiting terminal 12.

17. A decision entity for a packet service in a communication network, where in accordance with said packet service a communication with a given packet service terminal involves a terminal serving entity supporting said packet service and arranged for performing access control with respect to said given packet service terminal, and a gateway entity supporting said packet service and arranged for providing interworking with other networks, where said decision entity comprises:
-
a receiver for receiving tunneled packet data traffic of a visiting packet service terminal from a terminal serving entity of said communication network, wherein said terminal serving entity is a Serving GPRS Support Node (SGSN) a controller for performing a decision procedure for deciding whether the decision entity tunnels said packet data traffic from said visiting packet service terminal to a gateway entity of said communication network to process said packet data traffic in said gateway entity of said communication network, or tunnels said packet data traffic on to a home communication network of said visiting packet service terminal, and the decision entity being arranged to perform the decision procedure for packet data traffic received from a plurality of different terminal serving entities of the communication network. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. An address providing entity for a communication network that supports a packet service, where in accordance with said packet service a communication with a given packet service terminal involves a terminal serving entity supporting said packet service and arranged for performing access control with respect to said given packet service terminal, and a gateway entity supporting said packet service and arranged for providing interworking with other networks, said communication network comprising a decision entity configured to receive packet data traffic from said visiting packet service terminal and decide whether the decision entity tunnels said packet data traffic from said visiting packet service terminal in a gateway entity of said communication network to process said packet data traffic in said gateway of said communication network, or tunnels said packet data traffic on to a home communication network of said visiting packet service terminal, said address providing entity comprising:
-
a receiver for receiving an address query from a terminal serving entity of said communication network, wherein said terminal serving entity is a Serving GPRS Support Node (SGSN) said address query comprising a network identification part, and a controller for responding to said address query with an address of said decision entity at least if the network identification part of said address query indicates a home communication network of said visiting packet service terminal. - View Dependent Claims (26)
