Embodiment approach 1

[0034] figure 1 It is a diagram showing a configuration example of Embodiment 1 of the wireless communication system of the present invention. Such as figure 1 As shown, the wireless network system according to this embodiment includes wireless nodes (wireless communication devices) 1 to 6 . The wireless node 1 (shared node) is a wireless node belonging to both the first wireless network system 7 and the second wireless network system 8 . The wireless nodes 2 , 3 , 4 , and 5 serve as the first wireless network system 7 , and the wireless nodes 2 and 3 are adjacent nodes of the wireless node 1 in the first wireless network system 7 . The wireless nodes 1 to 5 are connected to wireless nodes adjacent to each other through wireless lines to form a first wireless network system 7 . The wireless node 6 is a wireless node belonging to the second wireless network system 8 , and is connected to the wireless node 1 through a wireless line to form the second wireless network system 8...

Embodiment approach 2

[0053] Figure 7 It is a sequence diagram showing an example of the operation sequence of Embodiment 2 of the wireless network system of the present invention. The configuration of the wireless network system of this embodiment and the configuration of each wireless node constituting the wireless network system are the same as those of the first embodiment.

[0054] In Embodiment 1, when the wireless node 1 returns to the first system, the neighboring nodes are notified of temporary unavailability and recovery from unavailability by sending a notification message, but in this embodiment, by notifying the unavailable time , omitting to send a message for notifying that the temporary node is unavailable.

[0055] Such as Figure 7 As shown, if the wireless node 1 receives a communication start request message from the wireless node 6 (step S31), it will notify the wireless nodes 2 and 3 as adjacent nodes that the temporary node is unavailable through the operation of the syste...

Embodiment approach 3

[0060] Figure 8 It is a diagram showing a configuration example of the third embodiment of the wireless node 1a constituting the wireless network system of the present invention. Figure 9 It is a diagram showing a configuration example of Embodiment 3 of a wireless node 6a (a wireless node belonging to the second system) constituting the wireless network system of the present invention. The configuration of the wireless network system according to the present embodiment is the same as that of the first embodiment except that the wireless nodes 1 and 6 of the first embodiment are replaced with wireless nodes 1a and 6a, respectively.

[0061] In Embodiments 1 and 2, the notification of the change of the wireless network system to which the wireless node 1 belongs is realized by a message, but in this embodiment, it is realized by information of the wireless network layer instead of a message.

[0062] Such as Figure 8 As shown, in addition to the wireless node 1 of the firs...

Abstract

A radio communication system allows for coexistence of a plurality of radio network systems. A radio node (1), which belongs to a first radio network system and temporarily belongs to a second radio network system, comprises a system cooperation control unit (13) that, when the radio node (1) starts to operate as a radio node belonging to the second radio network system, informs that the radio node (1) will be temporarily unavailable. When having received the information that the radio node (1) will be temporarily unavailable, a radio node, which belongs to the first radio network system and which is adjacent to the radio node (1), changes a radio communication parameter used between the local radio node and the radio node (1) to a value for which the radio node (1) will not be detected as an obstacle.

Description

technical field [0001] The present invention relates to a wireless communication system, a wireless communication device, and a wireless communication method. Background technique [0002] When a wireless node is shared among a plurality of wireless network systems (for example, wireless network system #1 and wireless network system #2), the wireless node cannot operate as a node of wireless network system #1 while the wireless node is operating as a node of wireless network system #1. 2 node action. In such a case, it appears that a failure has occurred at the wireless node in the network of the wireless network system #2. As a result, on the wireless network system #2 side, network processing such as an operation for bypassing the routing table change processing of the wireless node is performed. [0003] In order to prevent the wireless nodes shared between the wireless network systems from being regarded as faulty nodes, it is enough to enable multiple wireless network...
