FIELD: radio engineering, communication.SUBSTANCE: method involves providing a 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 radio network for a mobile terminal; providing information on neighbouring macro cells in which the local breakout service can continue, the macro cells belonging to a network using another tracking area than that of the serving cell of the mobile terminal; executing a handover process of the mobile terminal from a source base station in the serving cell of the mobile terminal to a target base station in a neighbouring macro cell; and providing session continuation of the mobile terminal local breakout service traffic in the neighbouring macro cell by controlling user plane tunnelling between the target base station and the local packet switched network from which an Internet protocol address for the local breakout service was assigned.EFFECT: high user mobility.34 cl, 21 dwg |
