Radio network system and control node switching method
First Claim
1. A radio network system which includes one control node for setting its own address into a control node address at the time of activating a network, a plurality of general nodes each for setting its own address on the basis of control by said control node when associating with the network and which makes multihop communication of radio data by using each of the addresses between the nodes, and at least one alternate control node that is substitutable for said control node, the alternate control node including:
- a control node monitoring component, which monitors an operating state in said control node;
an operating state discriminating component, which discriminates whether or not said operating state is abnormal; and
an upon-abnormality address setting component which sets its own address into said control node address when the operating state discriminating component determines that said operating state is abnormal,wherein as the monitoring of said operating state, said control node monitoring means monitors a communicating state of the radio data transmitted from said general node to said control node.

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.

4. A control mode switching method in a radio network system which includes one control node for setting its own address into a control node address at the time of activating a network and a plurality of general nodes each for setting its own address on the basis of control by said control node when associating with the network and which makes multihop communication of radio data by using each of the addresses between the nodes, comprising:
-
an alternate control node association control step of allowing at least one alternate control node which can be substituted for said control node to be associated as said general node with the network; a control node monitoring step of monitoring an operating state in said control node; an operating state discriminating step of discriminating whether or not said operating state is abnormal; and an upon-abnormality address setting step of setting an address of said alternate control node into said control node address when the operating state discriminating step determines that said operating state is normal, wherein said control node monitoring step includes monitoring a communication state of the radio data transmitted from the general node to the control node.

5. A radio network system, which includes one control node for setting its own address into a control node address at the time of activating a network, a plurality of general nodes each for setting its own address on the basis of control by said control node when associating with the network and which makes multihop communication of radio data by using each of the addresses between the nodes, and at least one alternate control node that is substitutable for said control node, the alternate control node including:
-
a control node monitoring means for monitoring an operating state in said control node; an operating state discriminating means for discriminating whether or not said operating state is abnormal; and an upon-abnormality address setting means for setting its own address into said control node address when the operating state discriminating means decides that said operating state is abnormal, wherein as the monitoring of said operating state, said control node monitoring means monitors a communicating state of the radio data transmitted from said general node to said control node. - View Dependent Claims (6, 7)
