Abstract

There is provided a session sharing system for sharing sessions in a system in which one or more application servers cooperate for plural applications including: a first function processor; a second function processor; and a session information cooperation unit for converting session information of a session established with an application server, which is acquired from the first function processor or the second function processor, into a predetermined format and giving the converted session information to the second function processor or the first function processor, wherein the second function processor or the first function processor transmits, to an application server, a request message including the converted session information received from the session information cooperation unit, and the application server associates the converted session information included in the request message with session information that is generated based on a current communication processing protocol.

Claims

1. A session sharing system for sharing sessions in a system in which one or more application servers cooperate for plural applications comprising:

a first function processor for receiving a first application service from an application server by a first communication processing protocol;

a second function processor for receiving a second application from an application server by a second communication processing protocol; and

a session information cooperation unit for converting session information of a session established with an application server, which is acquired from the first function processor or the second function processor, into a predetermined format and giving the converted session information to the second function processor or the first function processor,

wherein

the second function processor or the first function processor transmits, to an application server, a request message including the converted session information received from the session information cooperation unit, and

the application server associates the converted session information included in the request message with session information that is generated based on a current communication processing protocol.

2. The session sharing system according to claim 1, wherein

the session information cooperation unit converts session information of a session previously established with an application server into a communication protocol format used in the current communication.

3. The session sharing system according to claim 1, wherein

a first user terminal includes the first function processor and the session information cooperation unit,

a second user terminal includes the second function processor and the session information cooperation unit,

the session information cooperation unit of the first user terminal converts the session information into a two-dimensional code and displays the converted two-dimensional code on a display unit, and

the session information cooperation unit of the second user terminal reads the two-dimensional code displayed on the display unit of the first user terminal and restores the session information.

4. The session sharing system according to claim 1, wherein

each application server includes:

a server information providing unit configured to transmit information containing established session information and server identification information thereof to a user terminal; and

a message distributing unit for receiving a request message including the session information and the server identification information transmitted from the second function processor or the first function processor and distributing the request message based on the server identification information.

5. A session sharing method for sharing sessions in a system in which one or more application servers cooperate for plural applications comprising the steps of:

receiving a first application service from an application server by a first communication processing protocol, by a first function processor;

receiving a second application from an application server by a second communication processing protocol, by a second function processor;

converting session information of a session established with an application server, that is acquired from the first function processor or the second function processor, into a predetermined format and giving the converted session information to the second function processor or the first function processor, by a session information cooperation unit;

transmitting a request message including the converted session information from the session information cooperation unit to an application server, by the second function processor or the first function processor; and

associating the converted session information included in the request message with session information generated by a current communication processing protocol, by the application server.

6. A session sharing program for a user terminal in a session sharing system in which one or more application servers share sessions and cooperate for plural applications, the program causing the user terminal to function as:

a first function processor for receiving a first application service from an application server by a first communication processing protocol;

a second function processor for receiving a second application from an application server by a second communication processing protocol; and

a session information cooperation unit for converting session information of a session established with an application server, which is acquired from the first function processor or the second function processor, into a predetermined format and giving the converted session information to the second function processor or the first function processor,

wherein

the second function processor or the first function processor transmits a request message including the converted session information received from the session information cooperation unit to an application server.

7. A user terminal configured in a session sharing system in which one or more application servers share sessions and cooperate for plural applications, the user terminal comprising:

a first function processor for receiving a first application service from an application server by a first communication processing protocol;

a second function processor for receiving a second application from an application server by a second communication processing protocol; and

a session information cooperation unit for converting session information of a session established with an application server, that is acquired from the first function processor or the second function processor, into a predetermined format and giving the converted session information to the second function processor or the first function processor,

wherein

the second function processor or the first function processor transmits, to an application server, a request message including the converted session information received from the session information cooperation unit.
