Service apparatus, method of controlling switching of connection destination of client apparatus by service apparatus, and storage medium readable by machine
First Claim
1. 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 selecting unit selecting a client apparatus to which connection should be disconnected when a predetermined state is detected;
a requesting unit requesting other service apparatuses connected through a network to return a response, which indicates that connection is possible, in response to a probe request from the selected client apparatus; and
a unit inhibiting transmission of the response, which indicates that connection is possible, corresponding to the probe request from the selected client, for a given period of time, after the connection with the selected client apparatus is disconnected.

Abstract
To decentralize concentration of clients of a wireless LAN to a service apparatus of the wireless LAN. When a service apparatus detects a predetermined state, the service apparatus selects one of plural client apparatuses connected to the own apparatus and selects a client apparatus to which connection should be cut when the predetermined state is detected. 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 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. On the other hand, the determined another service apparatus responds to the probe request and the other services apparatuses inhibit transmission of a response, which indicates that connection with the client is possible, for a given period of time in response to the probe request.

10. 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, wherein
the service apparatus selects a client apparatus to which connection should be disconnected when a predetermined state is detected, requests other service apparatuses connected through a network to return a response, which indicates that connection is possible, in response to a probe request from the selected client apparatus; - and
inhibits transmission of the response, which indicates that connection is possible, corresponding to the probe request from the selected client, for a given period of time, after the connection with the selected client apparatus is disconnected.

11. A storage medium readable by a machine, storing a program for
causing 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, to perform control for switching a connection destination of the client apparatus, the program comprising steps of: -
selecting a client apparatus to which connection should be disconnected when a predetermined state is detected, requesting other service apparatuses connected through a network to return a response, which indicates that connection is possible, corresponding to the probe request from the selected client apparatus, and inhibiting transmission of the response, which indicates that connection is possible, corresponding to a probe request from the selected client, for a given period of time, after the connection with the selected client apparatus is disconnected.
