Handling of Local Breakout Traffic in a Home Base Station
First Claim
1. A method in a mobile terminal for forwarding of traffic, wherein said mobile terminal has a radio connection to a home base station, the home base station has a connection to a local network comprising a number of local nodes, a connection to a core network of a mobile telecommunications system via an access network, and a connection to the Internet via the access network, wherein said method comprises:
- identifying uplink traffic to be subject to local breakout transportation, wherein local breakout transportation implies forwarding the uplink traffic to a local node and/or the Internet without passing the core network;
communicating with the home base station using signaling to establish a dedicated local breakout bearer for traffic subject to local breakout transportation, wherein the local breakout bearer is a radio bearer that extends between the mobile terminal and the home base station; and
sending said identified uplink traffic to the home base station on the established local breakout bearer.

Abstract
The present invention relates to methods and devices that allow for efficient transportation of traffic in conjunction with a home base station (1). Traffic arriving in the home base station from a mobile terminal (2) connected to the home base station can be transported by means of local breakout transportation, which implies that the traffic is forwarded to a local node (4) over a local network (20) or to the Internet (21) without passing a core network (15) of a mobile telecommunications system. A local breakout bearer (22) is established, which is a radio bearer that extends between the mobile terminal and the home base station. The mobile terminal forwards uplink traffic that is to be subject to local breakout transportation to the home base station on the local breakout bearer. Thus it is not required for traffic that is destined for local nodes or the Internet to pass the core network, which allows for efficient traffic forwarding.
