Implementing control signallings in a telecommunication system comprising
at least one terminal and one telecommunication network, the
telecommunication network comprising at least one access network and one
or more core networks. Within a certain time, the terminal determines the
detected control signalling needs and transmits a request for maintaining
a radio connection to the telecommunication network if several control
signallings are to be carried out. The control signallings are carried out
successively between the terminal and one or more core networks without
releasing the radio connection between the terminal and the access
network.
