Abstract:
A method of managing circuit-switched calls in a mobile communications network supporting packet-switched sessions is performed as follows: upon reception by the mobile communications network of a circuit-switched call for a user of the mobile communication network, the network ascertains whether the user is engaged in a packet-switched session. In the affirmative case, the network closes the packet-switched data exchange session prior to attempting to route the call to the user.
