Abstract

A method for managing communication sessions in a radiocommunication system comprising a core network including a plurality of nodes and a radio access network including at least one radio network controller connected to a respective set of core network nodes, each ongoing session being served by a core network node in cooperation with a radio network controller. The ongoing sessions served by a first core network node in cooperation with a radio network controller are relocated to be served by at least one second core network node in cooperation with said radio network controller, when the first core network node is no more available to continue to serve said ongoing sessions, the first and second core network nodes belonging to the set of core network nodes to which said radio network controller is connected.
