Abstract

In an embodiment, an apparatus is configured to receive traffic of different traffic types, and to route the different traffic types to different paths or networks, the different traffic types comprising internet service domain traffic and operator'"'"'s service domain traffic. The apparatus may for example be a gateway of an access services network e.g. of worldwide interoperability of microwave access, WiMAX.

Claims

1. An apparatus configured to receive traffic of different traffic types, and to route the different traffic types to different paths or networks so as to provide a local breakout function or device, the different traffic types comprising internet service domain traffic and operator'"'"'s service domain traffic.

2. The apparatus according to claim 1, wherein the apparatus is a gateway or a device, module or chip of a gateway or another device.

3. The apparatus according to claim 2, wherein the gateway is an access service network gateway.

4. The apparatus according to claim 2, wherein the gateway is a worldwide interoperability of microwave access, WiMAX gateway.

5. The apparatus according to claim 2, wherein the gateway comprises at least one of a switch configured to switch incoming traffic to internet service domain traffic path or operator'"'"'s service domain traffic path, a data path function, a foreign agent, and a network address translation function or network address port translation function.

6. The apparatus according to claim 5, wherein the switch is at least one of a layer 3 switch and a public or private switch.

7. The apparatus according to claim 5, wherein the switch is provided between the data path function or a gateway input, and the foreign agent or other traffic tunnel end point.

8. A method comprising,

receiving traffic of different traffic types, routing the different traffic types to different paths or networks so as to provide a local breakout,

the different traffic types comprising internet service domain traffic and operator'"'"'s service domain traffic.

9. Method according to claim 8, wherein local breakout rules, e.g., detecting and switching rules, are transferred between access service network gateways if a breakout point is re-anchored.

10. Method according to claim 8, wherein local breakout rules are provisioned into access service network gateway with authorization or dynamically with policy control or using operation and maintenance provisioning.

11. Method according to claim 8, wherein a permission to allow local break-out can be provided by operation and maintenance, O&

M, or can be sent to the ASN-GW 6 with authorization or pushed dynamically.

12. A computer program product including a program comprising software code portions for performing, when the program is run on a processing device, any of the steps of the method according to claim 8.

13. A computer readable medium storing a computer program product according to claim 12.

14. Apparatus comprising means for receiving traffic of different traffic types, and means for routing the different traffic types to different paths or networks, the different traffic types comprising internet service domain traffic and operator'"'"'s service domain traffic.
