Abstract

When a new connection needs to be established in a mobile radio network between the core network and the radio access network to terminate a local circuit switched (CS) call, i.e. a CS call for which another connection has already been established between the core network and the same radio access network, the core network includes an optional information element containing “Other party information” in the messages that establish the new connection, allowing the radio access network to correlate the two connections, put them in direct communication and exclude the core network from the user plane data flow.
