Method and device for session control in hybrid telecommunications network

A method for providing session control within a telecommunications system comprising at least two networks of at least two different network types, where the networks are connecting at least a first user equipment and a network entity, where the first user equipment and the network entity have network connections to at least two of the networks of different network type the method comprising the steps of:

• detecting an event within a first communication session, said communication session being present on the network of a first network type, wherein the event is a Call Hold event or a termination event;
• composing a first message based on said event;
• providing the first message to a network node comprised within the network of the first network type so as to control the first communication session, composing a second message based on said event,
• providing the second message to a network node, so as to control a second communication session, being present on the network of a second network type;
• wherein the first and the second communication session are present simultaneously on the networks of the different network types and where the first and the second communication sessions are combinational.
