Abstract
A method for managing a degraded mode of a cell of a cellular network including a site controller for controlling, via a packet network, transmitters distributed over various sites of the cell such that transmitters implementing the same pair of frequencies over different sites form a channel which, in dynamic mode, is allocated dynamically to any communication between terminals of the cell, the channel including a master transmitter selected by the controller. The method includes, in each master transmitter on detection of a failure of the controller: switching in degraded mode of the master transmitter, by associating with the channel a predefined communication known to the terminals, and transmission from the master transmitter, via the network, of a control message informing a control console connected to the packet network of the implementation of the degraded mode so that the console participates in a communication underway in the channel.
