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.

Method for managing voice calls during packet-switched sessions, and mobile communications network implementing the method

A method of making network services available to a subscriber of a first mobile communications network when the subscriber roams in a second mobile communications network. The method includes: intercepting a signaling message issued by a service switching function of the second mobile communications network as a consequence to a service request by the subscriber; checking the intercepted signaling message; and based on the check, updating the intercepted signaling message so as to include service addressing data adapted to invoke a service in the first mobile communications network.
