DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection-based client-server processing system controlled by a client communicating with a server.

[0002]

2. Description of the Related Art In a conventional connection-based client-server type processing system, when a process requiring communication between a client and a server is performed, once communication between the client and the server is established, the communication between the client and the server is thereafter performed. During operation, communication between the client and the server remains connected regardless of the presence or absence of communication between the client and the server. That is, after performing a process that requires communication between the client and the server, the connection between the client and the server is maintained even when the client performs a process that does not require communication with the server. Then, in order to disconnect the communication between the client and the server and release communication resources (sockets and the like) of the server, it is necessary to wait until all operations of the client are completed.

In a connection-based client-server processing system, only the same number of clients as the number of communication resources provided in the server can simultaneously communicate with the server. Therefore, when the number of clients equal to or greater than the number of communication resources of the server is connected to the server, and when it becomes necessary for a predetermined client to communicate with the server, all communication resources are communicated with other clients. When the communication is blocked, the client must wait for execution of a process that needs to communicate with the server until one of the clients ends the operation and the communication resource is released. Was.

[0004]

As described above, in the conventional connection-based client-server processing system, the client cannot communicate with the server because all communication resources of the server are blocked. This is very inefficient because it is necessary to wait for the connection of communication with the server until the operation of one of the clients to which the communication resources of the server is allocated ends and the communication resources are released. Had the disadvantage that

[0005] The present invention solves the above-mentioned conventional disadvantages, and appropriately suspends communication between a client and a server except when the client performs a process that requires communication with the server.
It is an object of the present invention to provide a connection-based client-server processing system in which many clients can efficiently communicate with a server.

[0006]

In order to achieve the above object, the present invention provides a connection-based client-server processing system in which a client is controlled by communicating with a server. Communication interruption means for interrupting communication with the client; a communication state storage table for storing information on a communication state between the client and the server when the communication interruption means interrupts communication between the client and the server; Communication restart means for first transmitting information stored in the communication state storage table to the server when communication with the server is restarted.

[0007] In another connection-based client-server processing system that achieves the above object, in addition to the above-described configuration, the communication suspending means is provided when an event that suspends communication between the client and the server occurs. The information on the state of communication between the client and the server is stored in the communication state storage table, and then the communication is disconnected.

Another connection-based client-server processing system which achieves the above object is provided with communication time storage means for measuring and storing a communication connection time between a client and a server in addition to the above configuration. The communication time storage means stores a communication start time and an elapsed time from the communication start time each time an event for performing communication between the client and the server rises, and the communication interruption means is stored in the communication time storage means. When a certain period of time has elapsed from the time when the last communication was started with reference to the time information, the information on the state of communication between the client and the server is stored in the communication state storage table, and then the communication is disconnected. I have.

In another connection-based client-server processing system that achieves the above object, in addition to the above configuration, the number of key inputs for performing processing that does not require communication between the client and the server is counted. Key input number storage means for storing the number of key inputs for raising the event when an event that does not require communication between the client and the server occurs. The communication interrupting means refers to the key input number information stored in the key input number storage means and, when the set value exceeds a preset value, information on the state of communication between the client and the server. The communication is saved after being stored in the communication state storage table.

[0010]

According to the present invention, when a communication interruption means receives an event for interrupting communication from an input device or the like on the client side, and when a predetermined time has elapsed since the communication between the client and the server has started. Or, if a key input for performing processing that does not require communication with the server is performed a certain number of times or more, the communication between the client and the server is cut off even if the operation of the client is ongoing. Communication resources can be released.

Further, the communication suspending means saves information relating to the communication state when disconnecting the communication between the client and the server, and the communication resuming means firstly resumes the information relating to the communication state when resuming the communication between the client and the server. To the server, the client does not need to set the processing environment again when resuming communication with the server, and can resume communication as if it had been communicating with the server continuously. it can.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, an example in which the connection-based client / server processing system of the present invention is applied to a kana-kanji conversion system will be described. In this example, it is assumed that the input is Roman character input, the conversion process is performed by the client alone when converting Roman characters to kana characters, and communication with the server is required when converting kana characters to kanji characters.

FIG. 1 is a block diagram showing the configuration of a first embodiment of a kana-kanji conversion system using a client-server type processing system according to the present invention. As illustrated, the kana-kanji conversion system of the present embodiment includes a client 10 and a server 20. The client 10 is provided with a client-side input device 10 for performing various key inputs, and a communication state storage table 30 for storing information regarding the communication state between the client 10 and the server 20.

The client 10 and the server 20 are a client-type processing device and a server-type processing device similar to those in the conventional client-server type processing system. Although a plurality of clients 10 are actually connected to the server 20, they are not shown in the figure.

The client-side input device 11 uses a keyboard, a mouse, and the like, and is used for inputting various data such as Roman characters and inputting commands such as conversion keys. In this embodiment, when a kana-kanji conversion key is input from the client-side input device 11, the client 1
This means that an event connecting the communication between the server 0 and the server 20 has occurred.

The communication state storage table 30 stores information on the communication state between the client 10 and the server 20, such as server addresses, dictionary selection information, and environment customization information in conversion processing.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. 2 and FIGS. When a kana-kanji conversion key is input from the client-side input device 11 and an event for connecting the communication between the client 10 and the server 20 occurs (step 201), the client 20 is released on the condition that the communication resources of the server 20 are released. 10 connects communication with the server 20 (step 20).
2).

At this time, if the information on the communication state is stored in the communication state storage table 30, the client 10 first connects after the communication between the client 10 and the server 20 is connected as shown in FIG. Predetermined information is extracted from the communication state storage table 30 and sent to the server 20. Thereafter, a kana-kanji conversion process that requires communication with the server 20 is performed.

Thus, after the communication between the client 10 and the server 20 is connected, it is not necessary to first set the communication state. However, the communication state storage table 3
If the information regarding the communication state is not stored in 0 (for example, when the client 10 is activated and first connected to the server 20), it is needless to say that the necessary communication state must be set.

Next, a command key for cutting off communication with the server 20 is input from the client-side input device 11,
When an event for disconnecting the communication between the client 10 and the server 20 occurs in the system (step 203), the client 10 first proceeds to the server 20 as shown in FIG.
The information on the current communication state with the server 2 is stored in the communication information storage table 30 (step 204).
The communication with 0 is disconnected (step 205).

As described above, in the present embodiment, when there is no need for communication between the client 10 and the server, an event for disconnecting the communication is raised to increase the client 10.
Client 10 and server 2 even if the operation of
0 can be disconnected, and the communication resources of the server 20 can be released.

FIG. 5 is a block diagram showing the configuration of a second embodiment of the kana-kanji conversion system using the client-server type processing system of the present invention. As shown in the figure, the kana-kanji conversion system of the present embodiment includes a client 10, a client-side input device 10, a server 20, and a communication state storage table 30 similar to those of the first embodiment described above. And a communication time storage unit 40 for measuring and storing the communication connection time between the client and the server.

The communication time storage section 40 measures the start time of the communication and the elapsed time from the communication start time each time an event for performing communication between the client 10 and the server 20 occurs when the kana-kanji conversion key is input. Remember.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. 6, and FIGS. When a kana-kanji conversion key is input from the client-side input device 11 and an event connecting the communication between the client 10 and the server 20 occurs (step 601), the client 20 is released on the condition that the communication resources of the server 20 are released. 10 connects communication with the server 20 (step 60).
2).

At this time, if the information on the communication state is stored in the communication state storage table 30, the client 10 first connects after the communication between the client 10 and the server 20 is connected as shown in FIG. Predetermined information is extracted from the communication state storage table 30 and sent to the server 20. Thereafter, a kana-kanji conversion process that requires communication with the server 20 is performed. In addition, when communication with the client 10 and the server 20 is connected, the time when the communication is started is stored in the communication time storage unit 40. The communication time storage unit 40 stores the communication start time and measures and stores the elapsed time thereafter.

Here, the client 10 refers to the time information stored in the communication time storage unit 40 at predetermined time intervals. Then, when a predetermined period of time has elapsed since the last communication with the server 20 has started, the client 10 first determines the current communication state with the server 20 as shown in FIG. The information is stored in the communication information storage table 30 (step 603,
604) Then, the communication with the server 20 is disconnected (step 605).

As described above, in this embodiment, if the communication between the client 10 and the server has not been performed for a certain period of time, the communication between the client 10 and the server 20 will continue even if the operation of the client 10 is continuing. Can be automatically disconnected and the communication resources of the server 20 can be released.

FIG. 9 is a block diagram showing the configuration of a third embodiment of the kana-kanji conversion system using the client-server processing system of the present invention. As shown in the figure, the kana-kanji conversion system of the present embodiment includes a client 10, a client-side input device 10, a server 20, and a communication state storage table 30 similar to those of the first embodiment described above. And a key input number storage unit 50 for counting and storing the number of key inputs for performing processing that does not require communication between the client and the server.

The number-of-key-inputs storage unit 50 stores the client 1
After the communication between the client 10 and the server 20 is established after the communication between the client 10 and the server 20 has occurred, such as the input of Roman characters or the conversion of Roman kana characters, the number of key inputs is accumulated. Remember.

Next, the operation of the present embodiment will be described with reference to the flowchart of FIG. 10 and FIGS. 11, 12 and 13. When a kana-kanji conversion key is input from the client-side input device 11 and an event for connecting communication between the client 10 and the server 20 occurs (step 100).
1) On condition that the communication resources of the server 20 are released, the client 10 connects the communication with the server 20 (step 1002).

At this time, if the information on the communication status is stored in the communication status storage table 30, the client 10 first connects after the communication between the client 10 and the server 20 is connected as shown in FIG. Predetermined information is extracted from the communication state storage table 30 and sent to the server 20. Thereafter, a kana-kanji conversion process that requires communication with the server 20 is performed. When communication with the client 10 server 20 is established, the count of the number of key inputs in the key input number storage unit 50 is set to “0”.

Thereafter, when the client 10 performs processing that does not require communication with the server 20, such as inputting Roman characters and converting Romanized kana characters, the number of key inputs each time a key input for performing the processing is performed is performed. The storage unit 50 accumulates and stores the number of key inputs, and transmits the total number of key inputs to the client 10. At this point, as shown in FIG. 12, the communication connection between the client 10 and the server 20 is maintained. Here, when the client 10 communicates with the server 20, the count of the number of key inputs in the key input number storage unit 50 becomes "0" as described above, so that the number of key inputs is accumulated again from the beginning. It will be.

When the total number of key inputs sent from the key input number storage unit 50 to the client 10 exceeds a predetermined number of times, the client 10 first sets the server 20 as shown in FIG. The information about the current communication state with the server 20 is stored in the communication information storage table 30 (steps 1003 and 1004), and thereafter, the communication with the server 20 is disconnected (step 1005).

As described above, in the present embodiment, if processing that does not require communication between the client 10 and the server is performed a certain number of times or more, the client 10 and the server 10 continue to operate even if the operation of the client 10 is continued. The communication with the server 20 can be automatically disconnected, and the communication resources of the server 20 can be released.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments. For example, in this embodiment, three types of embodiments are shown for each condition for disconnecting the communication between the client and the server. However, in an actual system, the communication between the client and the server is disconnected by appropriately combining these embodiments. You may do so.

In this embodiment, the case where the present invention is applied to a kana-kanji conversion system has been described. However, as long as the system uses a normal connection-based client-server processing system, the present invention can be applied to other systems. It goes without saying that the invention can be used.

[0037]

As described above in detail, according to the present invention, when an event for interrupting communication occurs from an input device or the like on the client side, a certain period of time has elapsed since the communication between the client and the server was started. When the time has elapsed, or when a key input for performing processing that does not require communication with the server is performed a certain number of times or more, the communication between the client and the server is disconnected even if the operation of the client is continued. This has the effect that the communication resources of the server can be released as appropriate and many clients can communicate with the server efficiently.

Further, the communication suspending means saves information relating to the communication state when disconnecting the communication between the client and the server, and the communication resuming means firstly resumes the information relating to the communication state when resuming the communication between the client and the server. To the server, the client does not need to set the processing environment again when resuming communication with the server, and can resume communication as if it had been communicating with the server continuously. The communication between the client and the server can be performed more efficiently.
