ABSTRACT:
A radio network system and a control node switching method which can improve a reliability of the whole network and improve a wording efficiency. The system includes at least one alternate control node which can be substituted form the control node. The alternate control node monitors an operating state in the control node and discriminates whether or not the operating state is abnormal. When the operating state is determined to be abnormal, the alternate control node sets its own address into a control node address.
