Method, radio system, mobile terminal and base station for providing local breakout service

A method comprising:

• establishing a radio bearer for a local breakout service;
• providing a dynamic host control protocol relay function for mapping data of a mobile terminal using a local Internet protocol address to the established radio bearer;
• and
• providing the local breakout service to an Internet protocol gateway while retaining user access control and a remote Internet protocol gateway of a packet core network of a public mobile network for the mobile terminal.

A mobile terminal comprising:

• a communication unit configured to communicate with one or more base stations of a public mobile network;
• a processing unit configured to control functions of the mobile terminal;
• a detection unit configured to detect availability of a local breakout service to an Internet protocol gateway;
• a processing unit configured to start a network entry to the local breakout service;
• and
• a configuration unit configured to configure an Internet protocol stack of the mobile terminal on the basis of received configuration data in order to enter the local breakout service to the Internet protocol gateway while retaining user access control and a remote Internet protocol gateway of a packet core network of the public mobile network for the mobile terminal.

A base station, comprising:

• a communication unit configured to communicate with at least one mobile terminal, and with a local breakout service network providing Internet protocol gateway services;
• a detection unit configured to receive a network entry request to the local breakout service from the at least one mobile terminal;
• a processing unit configured to establish a radio bearer for the local breakout service;
• a mapping unit configured to provide a dynamic host control protocol relay function for mapping data of the mobile terminal using a local Internet protocol address to the established radio bearer;
• and
• a processing unit configured to provide the local breakout service to the Internet protocol gateway while retaining user access control and a remote Internet protocol gateway of a packet core network of the public mobile network for the mobile terminal.
