PURPOSE: A wireless network for preventing a wrong state is provided to release all resource when a key is transmitted erroneously to a terminal. CONSTITUTION: The wireless network includes a radio network controller(RNC) and a plurality of terminals. The radio network controller is responsible for controlling all the components playing a part in the radio traffic. An exchange of control and useful data takes place between the radio network controller and the terminals. The radio network controller sets up respective connections for the transmission of useful data. The layer model consists of three protocol layers, the physical layer(PHY), the data link layer with the sub layers(MAC and RLC) and the layer(RRC). The sub-layer(MAC) is used for the Medium Access Control, the sub-layer RLC for the Radio Link Control and the layer RRC for the Radio Resource Control. The layer RRC is responsible for the signaling between the terminals and the radio network controller. The sub-layer RLC is used for controlling a radio link between a terminal and the radio network controller. The layer RRC controls the layers MAC and PHY via the control links(10,11). Thus the layer RRC can control the configuration of the layers(MAC and PHY). The physical layer(PHY) offers transport links(12) to the MAC layer. The MAC layer renders logic links(13) available to the RLC layer. The RLC layer can be reached by applications via access points(14).
