Abstract

A server apparatus for establishing communication with a plurality of input/output devices via a network. The apparatus includes: a management unit configured to manage a communication session with the input/output devices; a storage unit configured to store information of the input/output devices in association with group information thereof; an execution unit configured to execute an application program; a communication unit configured to receive an operation instruction for the application program and to transmit to the input/output devices a processing result of the application program; a determination unit configured to determine whether the processing result requires connection of the input/output devices to an external server; and a message transmission unit configured to generate a message including an instruction to connect to the external server, when the determination unit determines that the processing results requires such a connection. The message includes the group information.

Claims

1. A server apparatus for establishing communication with a plurality of input/output devices via a network, the apparatus comprising:

a management unit configured to establish and manage a communication session with each of the input/output devices;

a storage unit configured to store information of the input/output devices in association with information of a group to which the input/output devices belong;

an execution unit configured to execute an application program;

a communication unit configured to receive from the input/output devices an operation instruction for the application program and to transmit to the input/output devices a processing result of the application program responsive to the operation instruction;

a determination unit configured to determine whether the processing result requires connection of the input/output devices to an external server; and

a message transmission unit configured to generate a message for instructing the input/output devices to connect to the external server, when the determination unit determines that the processing results requires connection of the input/output devices with the external server;

wherein the message includes information of the group.

3. The apparatus according to claim 1,

wherein, when the management unit receives information of the group from the input/output devices at the time of establishment of the communication session with the input/output devices, the management unit stores the information of the input/output devices in the storage unit in association with the group.

4. The apparatus according to claim 1,

wherein the input/output devices include a display device:

and

the storage unit stores information of an available display area from the apparatus in association with the display device.

5. The apparatus according to claim 4,

wherein the input/output devices include an input device;

the display device comprises an image display area that includes the available display area and an outside area other than the available display area, the outside area being available from the external server;

the determination unit determines whether an inputted instruction transmitted from the input device instructs a data input to the outside area; and

the message transmission unit generates and transmits the message when the determination unit determines that the inputted instruction instructs the data input to the outside area.

2. A terminal apparatus for establishing communication with servers via a network, the apparatus comprising:

a managing unit configured to manage a communication session with a first server;

a transmitting unit configured to transmit an operation instruction to the application program that runs on the first server;

a receiving unit configured to receive a message including a group information about a group to which the terminal belongs and an instruction to connect to a second server; and

an establishing unit configured to establish a communication session by making a connection with the second server so that the group information is provided to the second server.

6. A communication control method of a server apparatus for establishing communication with a plurality of input/output devices via a network and for running an application program, the method comprising:

establishing and managing a communication session with each of the input/output devices;

storing information of the input/output devices in association with information of a group to which the input/output devices belong;

receiving from the input/output devices an operation instruction for the application program;

transmitting to the input/output devices a processing result of the application program responsive to the operation instruction;

determining whether the processing result requires connection of the input/output devices to an external server; and

generating a message for instructing the input/output devices to connect to the external server, when it is determined that the processing results requires connection of the input/output devices with the external server;

wherein the message includes information of the group.
