Abstract: A method sets up a link with pre-paging to a called subscriber mobile terminal in a mobile radiotelephone network. A gateway telephone exchange sends a release instruction to the visitor subscriber database of the visited telephone exchange if the gateway telephone exchange has received from the calling mobile terminal, in the time interval since the transmission of the routing request, a message indicating that the setting up of the link is interrupted. On receiving that release instruction, a temporary identification reserved by routing, of resources associated to said identification as well as the resources booked by the search, for the interface between the telephone exchange and the radio subsystem, are released.
