The infrastructure comprises a network core, and radio network controllers linked to the core of the network. Base stations are provided with radio interfaces and are each connected to one of the controllers. A second path is established in a transfer procedure comprising the transmission of control data from the first to a second master controller, and the suppression of the first path. The infrastructure comprises a network core, and radio network controllers linked to the core of the network. Base stations are provided with radio interfaces and are each connected to one of the controllers. Digital information is transmitted on a first communication path in circuit mode between the core of the network and the terminal, passing through a first master controller, then on a second communication path in circuit mode between the core of the network and the terminal, passing through a second master controller. The second path is established in a transfer procedure comprising the transmission of control data from the first to the second master controller, and the suppression of the first path. This control data is representative of a current value of a sequence number used to number the information, incremented at regular intervals, and a shift between this sequence number and a time reference available to the second controller. |
