Abstract

A thin client system includes a thin client server, a thin client terminal, and a session management server. The thin client server contains a plurality of execution sections respectively provided for tasks. The session management server is configured to assign the thin client terminal to a specific one of the plurality of execution sections.

Claims

1. A thin client system comprising:

a thin client server comprising a plurality of execution sections respectively provided for tasks,

a thin client terminal; and

a session management server configured to assign said thin client terminal to a specific one of said plurality of execution sections.

2. The thin client system according to claim 1, wherein each of said plurality of execution sections comprises:

an operating system;

an application program provided for a corresponding task, and executed on said operating system; and

a data used by said application program.

3. The thin client system according to claim 1, wherein said thin client server further comprises:

a client status acquiring section provided for each of said plurality of execution sections to hold a status of said execution section.

4. The thin client system according to claim 1, wherein said session management server comprises:

a connection destination setting table configured to store an execution section data indicating each of said plurality of execution sections for a user data indicating a user of said thin client terminal and a terminal data indicating said thin client terminal; and

a session management section configured to search said connection destination setting table for said execution section data to said specific execution section based on said user data and said terminal data sent from said thin client terminal, and to connect said thin client terminal with said specific execution section of said thin client server based on said searched execution section data.

5. The session management system according to claim 4, wherein said thin client terminal has a secret key peculiar to said thin client terminal, and

said connection destination setting table stores a public key corresponding to said secret key as said terminal data.

6. The thin client system according to claim 4, wherein said session management server further comprises:

a connection state management table,

said session management section stores said execution section data, said user data, and said terminal data in said connection state management table when said thin client is connected with said specific execution section.

7. The thin client system according to claim 4, wherein said thin client terminal comprises:

a protocol management section configured to receives said execution section data, and to establish a connection with said thin client server through said session management server, by using a protocol and the received execution section data; and

a connection destination control section configured to acquire said execution section data in response to transmission of said user data and said terminal data, and to notify said execution section data to said protocol management server.

8. The thin client system according to claim 7, wherein said thin client terminal establishes the connection between said thin client terminal and said thin client server through said session management server, and

said session management section acquires said execution section data in response to reception of said user data and said terminal data from said thin client terminal, when the connection is disconnected, acquires a status of said specific execution section, and carries out reconnection of said thin client terminal when the status of said specific execution section indicates that said specific execution section is normal.

9. The thin client system according to claim 8, wherein said session management section restart said specific execution section when the status of said specific execution section indicates that said specific execution section is normal.

10. A session management server in a thin client system, comprising:

a connection destination setting table configured to store an execution section data indicating each of a plurality of execution sections provided for tasks for a user data indicating a user of a thin client terminal and a terminal data indicating said thin client terminal; and

a session management section configured to search said connection destination setting table for said execution section data to said specific execution section based on said user data and said terminal data sent from said thin client terminal, and to connect said thin client terminal with said specific execution section of said thin client server based on said searched execution section data.

11. The session management system according to claim 10, wherein said thin client terminal has a secret key peculiar to said thin client terminal, and

said connection destination setting table stores a public key corresponding to said secret key as said terminal data.

12. The session management system according to claim 10, further comprising:

a connection state management table,

wherein said session management section stores said execution section data, said user data, and said terminal data in said connection state management table when said thin client is connected with a specific execution section.

13. A thin client terminal comprising:

a protocol management section configured to receives an execution section data for a task, and to establish a connection with a thin client server through a session management server, by using a protocol and the received execution section data; and

a connection destination control section configured to acquire said execution section data in response to transmission of a user data and a terminal data, and to notify said execution section data to said protocol management server.

14. A session management method in a thin client system, comprising:

assigning a thin client terminal to a specific one of a plurality of execution sections respectively provided for tasks in a thin client server;

connecting said thin client terminal and said thin client server through a session management server; and

managing a status of the connection between said thin client terminal and said thin client server in said session management server.

15. The session management method according to claim 14, wherein said assigning comprises:

preparing a connection destination setting table, wherein said connection destination setting table stores an execution section data indicating each of said plurality of execution sections for a user data indicating a user of said thin client terminal and a terminal data indicating said thin client terminal; and

searching said connection destination setting table for said specific execution section based on said user data and said terminal data.

16. The session management method according to claim 15, further comprising:

reconnecting when said thin client terminal and said thin client server when said status of the connection between said thin client terminal and said thin client server indicates that the connection is disconnected but is in a use state.

17. The session management method according to claim 16, further comprising:

receiving an execution section data for a task;

acquiring said execution section data in response to transmission of a user data and a terminal data; and

notifying said execution section data to said protocol management server.

18. A computer-readable software product for achieving a method which comprises:

preparing a connection destination setting table, wherein said connection destination setting table stores an execution section data indicating each of a plurality of execution sections provided for tasks in a thin client server, for a user data indicating a user of a thin client terminal and a terminal data indicating said thin client terminal;

searching said connection destination setting table for a specific one of said plurality of execution sections based on said user data and said terminal data; and

reconnecting when said thin client terminal and a thin client server when said status of the connection between said thin client terminal and said thin client server indicates that the connection is disconnected but is in a use state.

19. The computer-readable software product according to claim 18, wherein said method further comprises:

receiving and holding said execution section data, said user data and said terminal data; and

20. The computer-readable software product according to claim 19, wherein said method further comprises:
