Claim Text:
1. A method of managing a cell of a radio telecommunication network, the cell comprising a site controller configured to control, via a packet network, a plurality of transmitters distributed over different sites of the cell such that the transmitters of the different sites transmitting over a same frequency band form a transmission channel, a channel of said transmission channel being a control channel dedicated to a transmission of signals relative to an operation of the cell, said signals comprising general operating signals and specific operating signals, the method comprising: transmitting a request comprising general operating signals from the site controller to a transmitter selected by said site controller to control storage of general operating signals in said selected transmitter, and to control handling of a transmission of said general operating signals addressed to all terminals present in the cell over said control channel in case of failure of the site controller and/or of the packet network such that in response to a failure of the site controller and/or of the packet network, the terminals continue to communicate on the transmission channel in the absence of a communication establishing operation and corresponding migration to a different cell, such that each terminal does not migrate until it requires a specific operating signal from the failed site controller and/or packet network, whereby migration of the terminals to the different cell is distributed in time in response to time distributed detection of the failure.
