Abstract:
1. A method for providing correlation means within a telecommunications system comprising two or more networks of different network type, the two or more networks being connected to at least a first user equipment and a network entity, where the first user equipment and the network entity have network connections, each network connection associated with a respective network address, to the two or more networks, the method comprising the steps of: setting up a first communication session by one of the first user equipment and the network entity towards the other of the first user equipment and the network entity, via the network of a first network type; setting up a second communication session by one of the first user equipment and the network entity towards the other of the first user equipment and the network entity, via the network of a second network type, including providing the network entity with a call session identifier being the network address of the first network type of the first user equipment, the first and second communication sessions being present on the two or more networks of different network type, the network types being a Circuit Switched network type and a Packet Switched network type, and providing a correlation node, connected to the two or more networks, with a Combinational Call Indicator (CCI) variable, the CCI indicating whether the first communication session is combinational with the second communication session, where the correlation node is adapted to determine that the first and the second communication session are combinational when the received CCI variable is set, wherein the setting up of the communication session that is present on the network of the Circuit Switched network type includes providing the CCI variable to the other of the first user equipment or the network entity towards which the communication session that is present on the network of the Circuit Switched network type is set up.
