When a service apparatus detects a predetermined state, the service apparatus selects one of a plurality of client apparatuses connected to the service apparatus and selects a client apparatus to which a connection should be cut. The service apparatus determines another service apparatus to be a redirection destination of the client through communication with other service apparatuses which are capable of establishing a connection with the client. The service apparatus gives control information to the other service apparatuses and inhibits transmission of a response, which indicates that connection with the client is possible, corresponding to a probe request from the client apparatus for a given period of time.
A service apparatus providing a radio connection service to client apparatuses by returning a response in response to a probe request from an unconnected client apparatus to execute a radio connection procedure with the client apparatus, and by returning a response in response to a probe request from a connected client apparatus to continue a connected state with the client apparatus, the service apparatus comprising:
A method of controlling switching of a connection destination of a client apparatus by a service apparatus included in a group of service apparatuses providing a radio connection service to client apparatuses by returning a response in response to a probe request from an unconnected client apparatus to execute a radio connection procedure with the client apparatus, and by returning a response in response to a probe request from a connected client apparatus to continue a connected state with the client apparatus,
A non-transitory storage medium readable by a service apparatus, storing a program for causing the service apparatus included in a group of service apparatuses providing a radio connection service to client apparatuses by returning a response in response to a probe request from an unconnected client apparatus to execute a radio connection procedure with the client apparatus, and by returning a response in response to a probe request from a connected client apparatus to continue a connected state with the client apparatus, to perform control for switching a connection destination of the client apparatus,
