Abstract

In order to define and validate a station in a same network easily by specifying a unique network ID in a wireless network system, by using the validation information including the unique network ID in the wireless network system, it is designed to execute, as required, a process of subscribing and connecting to an existing wireless network system in the own station, a process of building up a new wireless network system starting from the own station, a process of transmitting validation information to other station in non-registered state of network ID, as the own station subscribed to the existing wireless network system working as the control station, and a process of removing the station subscribed to the existing wireless network system from the network.

Dependent claims

A method of building a wireless network system using wireless transmission equipment comprising a mutual connection step of mutually connecting with another station or control station by exchanging first validation information including network ID (identification information unique to a wireless network system) specified in a wireless network system, a new participation step of newly participating in a wireless network system by receiving second validation information including the network ID, used when subscribing to the wireless network system corresponding to said network ID, a data input and output step of sending and receiving data together with management information including the network ID and a network ID updating step of registering or erasing the network ID, further comprising:

a step of mutually connecting with the wireless transmission equipment of another station or control station registering the network ID of the existing wireless network system, by executing the mutual connection step after setting the network ID of the wireless transmission equipment of the own station in non-registration state, and
a step of registering the network ID in the wireless transmission equipment of the own station by receiving the second validation information from the wireless transmission equipment of another station or control station, characterized in that the wireless transmission equipment of the own station is subscribed in the existing wireless network system.

A wireless transmission equipment comprising a wireless process unit, a data convert, unit for converting the data with management information including network ID (identification information unique to a wireless network system) for transmitting and receiving in the wireless process unit, an external device for sending and receiving data through the data convert unit and an interface, a control unit for controlling the operation of each part, and exchanging first validation information including the network ID used in mutual connection with the wireless transmission equipment of another station or control station, second validation information including the network ID used when subscribing to the wireless network system corresponding to the network ID and the management information, with the data convert unit, a memory for registering the network ID by the access from the control unit, and a reset switch for storing the command for erasing the network ID from the memory, further comprising:

mutually connection means for mutually connecting with another station or control station by exchanging the first validation information,
means for registering the network ID in the memory, by receiving the second validation information from another station or control station by the network ID is not registered in the own station but is registered in another station or control station, with the own station being mutually connected to another station or control station by the mutual connection means,
means for transmitting the management information including the newly set network ID to the wireless transmission equipment of another station after newly setting the unique network ID in a new wireless network system, when the own station is mutually connected to another station or control station by the mutually connection means, and the network ID is not registered either in the own station or in another station or control station,
means for transmitting the second validation information to the wireless transmission equipment of another station from the wireless transmission equipment of the own station when the own station is the control station, if the own station is mutually connected to another station or control station by the mutual connection means, and the network ID is registered in the own station and is not registered in another station or control station, and
means of receiving the management information when the management information is transmitted from the control station, and then returning the response to the received management information to the control station, when not mutually connected to another station or control station by the mutual connection means, and the network ID is registered in the own station, and the instruction of erasing the network ID from the memory (reset request) is not set in the reset switch.
