Abstract
A terminal station having a first mode to control communication and a second mode in which the communication is controlled by a terminal station operating in the first mode, comprising: a connection unit configured to connect the terminal station operating in the second mode to other terminal station operating in the first mode; and an acquisition unit configured to acquire a communication band from the other terminal station connected by the connection unit when starting an operation in the first mode.
Claims17
A communication system including a first terminal station which has a host function of controlling communication, and a device function controlled by the host function, and a second terminal station which operates by the host function,
- the second terminal station comprising:
- a determination unit configured to determine whether a connected terminal station is the first terminal station;
- and
- a control unit configured to, if the terminal station determined to be the first terminal station by said determination unit has acquired no communication band yet when starting an operation by the host function, assign at least part of a communication band acquired by the second terminal station to the first terminal station, and
- the first terminal station comprising:
- a host unit configured to operate by the host function when the first terminal station connected to the second terminal station by the device function has received a connection request from a third terminal station which operates by the device function;
- and
- an acquisition unit configured to, when starting an operation by the host function, acquire the communication band assigned by the second terminal station as a communication band for the third terminal station.
A control method in a communication system including a first terminal station which has a host function of controlling communication, and a device function controlled by the host function, and a second terminal station which operates by the host function, comprising:
- causing the second terminal station to assign at least part of a communication band acquired by the second terminal station to the first terminal station when the first terminal station connected to the second terminal station by the device function starts an operation by the host function;
- and
- causing the first terminal station to acquire the communication band assigned by the second terminal station when the first terminal station connected to the second terminal station by the device function starts an operation by the host function.
A terminal station having a first mode to control communication and a second mode in which the communication is controlled by a terminal station operating in the first mode, comprising:
- a connection unit configured to connect the terminal station operating in the second mode to other terminal station operating in the first mode;
- and
- an acquisition unit configured to acquire a communication band from said other terminal station connected by said connection unit when starting an operation in the first mode.
A terminal station comprising:
- a connection unit configured to connect the terminal station operating in a first mode to control communication to other terminal station operating in a second mode in which the communication is controlled by a terminal station operating in the first mode;
- and
- a control unit configured to assign at least part of a communication band acquired by the terminal station to said other terminal station when said other terminal station connected by said connection unit starts an operation in the first mode.
A computer-readable storage medium storing a computer program, the program causing a computer incorporated in a terminal station having a first mode to control communication and a second mode in which the communication is controlled by a terminal station operating in the first mode to function as:
- a connection unit configured to connect the terminal station to other terminal station operating in the first mode;
- and
- an acquisition unit configured to acquire a communication band from said other terminal station connected by said connection unit when starting an operation in the first mode.
A computer-readable storage medium storing a computer program, the program causing a computer incorporated in a terminal station to function as:
- a connection unit configured to connect the terminal station operating in a first mode to control communication to other terminal station operating in a second mode in which the communication is controlled by a terminal station operating in the first mode;
- and
- a control unit configured to assign at least part of a communication band acquired by the terminal station to said other terminal station when said other terminal station connected by said connection unit starts an operation in the first mode.
