1. A communication device comprising:

  • a state control unit which can operate the communication device in at least the following three useful data transmission states;

    a first useful data transmission state of a data link layer, in which a useful data communication link with first communication resources is allocated to the communication device,a second useful data transmission state of the data link layer, in which a useful data communication link with the first communication resources is allocated to the communication device, anda third useful data transmission state of the data link layer, in which a useful data communication link with second communication resources is allocated to the communication device, the second communication resources being fewer than the first communication resources; and

    a state transition control unit which can perform at least the following state transitions;

    a state change from the first useful data transmission state to the second useful data transmission state when a first state transition criterion has been met,a state change from the second useful data transmission state to the third useful data transmission state when a second state transition criterion has been met,a state change from the third useful data transmission state to the first useful data transmission state when a third state transition criterion has been met, anda state change from the second useful data transmission state to the first useful data transmission state when a fourth state transition criterion has been met.
