Abstract

PURPOSE:To attain the matching of a difference among the allocation processing of a host function, a function expected by a host computer, and a terminal function without applying a load on the AP (application program) of the host computer and the operator of a terminal equipment, by performing the automatic switching/allocation between the AP of a distributed process processor and the terminal equipment. CONSTITUTION:A decision means 12 decides by which AP of the distributed process processor 1 data can be processed, to which terminal communication is performed, and which AP of the distributed process processor 1 and terminal equipment 3 can be allotted and communicated, from information obtained from a reception means 11 and a session control means 19. A switching/allocation means 13 performs a session switching request, a session switching operation, and terminal allocation according to the information from the decision means 12 and the session control means 19. Also, a reception processing means 14 delivers the information received at the reception means 11 to the AP of the distributed process processor 1, and a transmission processing means 15 receives the information of a transmission request from the AP of the distributed process processor 1. And a transmission means 16 transmits the information delivered from the transmission processing means 15 to the terminal equipment and the host computer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a session control method in a computer system.

[Conventional technology]

Conventionally, multiple APs (application programs) of a distributed processing processor are connected to the A of the host computer in one session.
When communicating with P, both APs needed to perform session switching processing based on a session switching request from one of the APs. Further, when communicating between the AP of the distributed processing processor and the terminal device, a similar switching operation by the terminal operator or switching processing at the AP of the distributed processing processor is required.

[Problem that the invention seeks to solve]

In the conventional session control method, each time the processing AP of a distributed processing processor changes, the host computer's AP, the distributed processing processor's AP, or the operator of the terminal device issues a switching request. The disadvantage is that switching processing is required. Another disadvantage is that the session state between the host computer's AP and the distributed processing processor's AP and the session state between the distributed processing processor's AP and the terminal device do not match, causing inconvenience.

[Means for solving problems]

The system of the present invention includes: a receiving unit that receives data from a host computer and/or a terminal device; a session control unit that stores and controls the communication state between an AP of the host computer and an AP of a distributed processing processor; a determining means for determining, from information obtained from the session control means, which AP of the distributed processing processor is to be used for processing, which terminal device to communicate with, and whether the AP of the distributed processing processor and the terminal device can be assigned and communicated; and a session switching request and session switching operation according to information from the session control means.

a switching/allocation means for allocating a terminal; a reception processing means for passing information received by the reception means to an AP of a distributed processing processor; a transmission processing means for receiving information on a transmission request from an AP of a distributed processing processor; It has a transmitting means for transmitting the information handed over from the processing means to the terminal device and/or the host computer.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the system of the present invention. The receiving means 11 of the distributed processing processor 1 receives from the AP 211 of the host computer 2 and passes it to the determining means 12. The session control means 19 is an AP 21 of the host computer.
The communication states of the session 411 between the APIII of the distributed processing processor 1 and the APIII of the distributed processing processor and the session 511 of the session 511 between the APIIII of the distributed processing processor and the terminal processing device 311 are stored in advance in the storage device 123, and are controlled. Judgment method 1
2 determines which APll of the distributed processing processor is to be used for processing, which terminal device 3 to communicate with, and the APII of the distributed processing processor, based on the information delivered from the receiving means 11 and the information obtained from the session control means 19.
I, determine whether the terminal device 3 can be allocated, and if communication is possible, notify the switching/allocation means 13; if communication is not possible,
Refuse reception. The switching/allocation means 13
11 and session 511 is sent to the session control means 19. The session control means 19
The current session 4111511 is disconnected, it is determined whether a new session 4111511 can be set, the state of the new session 4111511 is stored in the storage device 123, and the switching/allocation means 13 is notified. The switching/' allocating means 13 selects the session 411/'511 when the communication controller fi121.122 can switch the session 411/'511.
11511 and allocate the terminal device, and notify the reception processing means 14. Further, the switching/allocation means 13 rejects reception if switching of the session 4111511 is impossible. The reception processing means 14 includes a switching/'allocation means 13
The received information is handed over to the APlll that was switched. A
When a transmission request is issued from the PIII to the terminal device 3]1, the transmission processing means IE picks up the request and hands it over to the transmission means IF.

The transmitting means IF transmits to the terminal processing device 311. Conversely, when the receiving means IA receives from the terminal processing device 311, the same as above applies to the determining means IB and the switching switch 7]C1
A of the host computer through the reception processing means ID, the transmission processing means 15, the transmission means 16, and one session control means.
Send to P211.

〔Effect of the invention〕

As explained above, the present invention provides an A
P. By automatically switching/allocating terminal devices, it is possible to divide the host functions and identify differences between the functions expected by the host computer and the terminal functions without placing a burden on the host computer's AP and terminal device operators. This has the effect of enabling consistency.
