    • PROBLEM TO BE SOLVED: To provide a wireless communication system and an information providing method capable of efficiently performing re-provisioning, thus reducing erroneous operation.SOLUTION: A wireless communication system 1 includes a provisioning device 50, a gateway 20, and a management device 40. The provisioning device 50 sets provisioning information for a wireless device 11 that is to join a wireless communication network N1. The gateway 20 performs join processing by using the provisioning information set by the provisioning device 50 for determining whether or not to allow the wireless device 11 to join the wireless communication network N1. The management device 40 manages join history information including the provisioning information set by the provisioning device 50 and join information associated with the provisioning information, where the join information indicates a result of the join processing by the gateway 20, and provides the join history information to the provisioning device 50 in response to a request from the provisioning device 50.
    • 要解决的问题:提供能够有效地执行重新配置的无线通信系统和信息提供方法,从而减少错误的操作。解决方案:无线通信系统1包括供应设备50,网关20和管理设备 配置设备50设置用于加入无线通信网络N1的无线设备11的配置信息。 网关20通过使用由供应设备50设置的供应信息来确定是否允许无线设备11加入无线通信网络N1来执行加入处理。 管理装置40管理包括由供应装置50设定的供应信息的连接历史信息,并且加入与供应信息相关联的信息,其中连接信息指示网关20的连接处理的结果,并且将连接历史信息提供给 供应设备50响应于来自供应设备50的请求。
