The present invention concerns a method for maintaining transparent mode radio bearers in a Radio Access Network (RAN) of a third generation mobile telecommunications network. The method relates to managing the radio resources allocated to a user equipment (UE) in said radio access network (RAN). The method generally comprises communicating a message from a radio resource controller (RRC) of the RAN to the UE where said message is arranged to instruct the UE to transition from a dedicated channel connection state to a lower activity connection state and to store in its memory transparent mode (TM) radio bearer (RB) information associated with said dedicated channel connection state. By storing TM RB information associated with the dedicated channel connection state, the UE can be reconfigured to the dedicated channel connection state without the RAN having to perform a radio bearer setup procedure.
