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.
Claims27
A method of controlling packet data traffic of a packet service in a communication network (10), where in accordance with said packet service a communication with a given packet service terminal (12) involves a terminal serving entity (101) supporting said packet service and arranged for performing access control with respect to said given packet service terminal, and a gateway entity (102) supporting said packet service and arranged for providing interworking with other networks, said method comprising:
- setting up (S41) a communication between a terminal serving entity (101) of said communication network (10) and a visiting packet service terminal (12) visiting said communication network (10),
- tunneling (S42) packet data traffic of said visiting packet service terminal (12) from said terminal serving entity (101) of said communication network to a decision entity (103) in said communication network (10), said decision entity (103) performing a decision procedure (S43) for deciding whether to process said packet data traffic in a gateway entity (102) of said communication network, or to tunnel said packet data traffic on to a home communication network (13) of said visiting packet service terminal (12), 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.
A decision entity (50;
- 103) 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 (501) for receiving tunneled packet data traffic of a visiting packet service terminal from a terminal serving entity of said communication network,
- a controller (502) for performing a decision procedure for deciding whether to process said packet data traffic from said visiting packet service terminal in a gateway entity of said communication network, or to tunnel 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.
An address providing entity (60) 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 for deciding whether to process packet data traffic from said visiting packet service terminal in a gateway entity of said communication network, or to tunnel said packet data traffic on to a home communication network of said visiting packet service terminal, said address providing entity comprising:
- a receiver (601) for receiving an address query from a terminal serving entity of said communication network, said address query comprising a network identification part, and
- a controller (602) 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.
