Abstract
A wireless communication system includes a plurality of mobile stations and a base station configured to connect the mobile stations wirelessly, wherein the base station includes a response request signal transmission module configured to transmit a response request signal to the mobile stations, and a first wireless connection control module configured to disconnect the wireless connection between the mobile stations when a response signal is not received from at least one of the mobile stations to which the response request signal has been transmitted.
Claims16
A wireless communication system comprising:
- a plurality of mobile stations and a base station configured to connect the mobile stations wirelessly,
- wherein the base station includes:
- a response request signal transmission module configured to transmit a response request signal to each of the mobile stations, which are connected wirelessly to each other via the base station, wherein the response request signal is transmitted during a period when there is no communication by the users of the mobile stations;
- and
- a first wireless connection control module configured to disconnect the wireless connection between the mobile stations when a response signal is not received from at least one of the mobile stations to which the response request signal has been transmitted;
- and
- a second wireless connection control module configured to disconnect the wireless connection between the mobile stations when communication between the mobile stations that are connected wirelessly is not performed for a first predetermined period of time,
- wherein the response request signal transmission module transmits the response request signal when communication between the mobile stations is not performed for a second period of time, the second period of time being shorter than the first period of time,
- wherein the first wireless connection control module transmits a disconnection signal upon disconnection of the wireless connection, and
- wherein the mobile station further comprises a notification module configured to notify a user that a mobile station that is other party of communication is in a communication-disabled condition, upon receipt of the disconnection signal.
A wireless connection control method used in a wireless communication system comprising a plurality of mobile stations and a base station configured to connect the mobile stations wirelessly, wherein the base station performs the steps of:
- transmitting a response request signal to each of the mobile stations, which are connected wirelessly to each other via the base station, wherein the response request signal is transmitted during a period when there is no communication by the users of the mobile stations;
- and
- disconnecting the wireless connection between the mobile stations when a response signal could not be received from at least one of the mobile stations to which the response request signal has been transmitted,
- disconnecting the wireless connection between the mobile stations when communication between the mobile stations that are connected wirelessly is not performed for a first predetermined period of time, and
- transmitting the response request signal when communication between the mobile stations is not performed for a second period of time, the second period of time being shorter than the first period of time
- wherein the base station performs transmitting a disconnection signal upon disconnection of the wireless connection, and
- wherein the mobile station performs notifying a user that a mobile station that is other party of communication is in a communication-disabled condition, upon receipt of the disconnection signal.
