2. Description of the Related Art Conventionally, in a reservation of a sports facility or a theater, a communication system constituted by a server connected to a database storing related data necessary for the reservation as shown in FIG. 5 and a plurality of communication terminals. Is widely used. The reservation process using such a communication system will be briefly described below with reference to FIG. FIG. 6 is a sequence diagram showing a reservation process using the communication system shown in FIG.

[0005] First, a request for reservation processing is transmitted from the communication terminal device 52 to the server device 51. Also, the server device 51
Provides a management table for the reservation related to the communication terminal device 52, searches the database 54 via the database processing device 53 for data necessary for the reservation, and transmits the result to the communication terminal device 52. I do. At this time, usually, the server device 51 creates an option related to a reservation item that can be selected by the user of the communication terminal device 52 from a search result from the database 54 and transmits the option to the communication terminal device 52. Next, the communication terminal device 52 selects a reservation item from the options and transmits it to the server device 51. The server device 51 stores the received reservation item in the management table, searches the database 54 for data on the reservation item, creates a more detailed option, and transmits it to the communication terminal device 52.

[0004] By repeating the same operation, the reservation item selected by the user of the communication terminal device 52 is stored in the management table while the server device 51 and the communication terminal device 52 transmit and receive each other. . Further, in any one of the multiple transmissions from the communication terminal device 52 to the server device 51, the ID information of the user of the communication terminal device 52 or the communication terminal device 52 itself is transmitted to the server device 51, and the ID information is The information is stored in association with the management table. Lastly, by transmitting the information for confirming the reservation item group transmitted from the communication terminal device 52 to the server device 51, the server device 51 stores the reservation item group stored in the management table in the communication terminal device 52. It is determined as the reservation information of the user or the like. As described above, in the conventional reservation communication system, the progress state of the reservation processing is managed on the server side from the start to the end of the reservation processing by the management table on the server side.

[0005]

In recent years, with the development of the Internet, communication systems using the WWW (World Wide Web) system for searching for information on the Internet have become widespread. If this WWW method is used in the reservation processing used, the Internet user can easily reserve sports facilities and the like, which is very useful.

[0006] However, the communication procedure between the server device and the communication terminal device in the WWW system is HTTP (HyperText Tr).
ansfer Protocol). Due to the nature of HTTP, when the server device and the communication terminal device perform transmission and reception a plurality of times, the connection between them is intermittently performed.
The connection cannot be maintained throughout. That is, HTTP
In the communication method of (1), only one response from the server is returned for one request from the communication terminal, and the connection state between the server and the communication terminal is determined when the request and the response are transmitted. Be cut off. Therefore,
From the viewpoint of the server, the plurality of requests are regarded as different communications, and even when continuous requests are made from the same communication terminal device, the server device side
The identity of the communication device cannot be recognized.

Therefore, when performing a reservation process using HTTP, the server device prepares one reservation application screen and transmits it to the data communication terminal, and the user of the communication terminal device receives ID information and a plurality of reservations. It is necessary to adopt a method of inputting all the items, sending a request to the server, and transmitting the request. In this case, the transmitting terminal must input and transmit all the information necessary for the reservation at one time. For this reason, for example, in the case of booking a sports facility,
For items such as facility name, desired date of use, event, time of use, etc., it is not possible to make inquiries such as availability at that time, and applications must be made regardless of whether there is space available There is a problem.

Further, if the data relating to the reservation is completely hierarchical, and if the data at the lowest layer can be derived, all the data at the higher level can be derived, the data at the lowest layer is associated with the ID information related to the communication terminal device. Then, all the reservation items selected on the communication terminal device side can be known on the server device side. Therefore, in this case, even when the connection state of the line cannot be maintained as in the case of HTTP, the server device and the communication terminal device perform a plurality of transmissions and receptions, and the communication terminal device inquires about the availability. Also becomes possible. However, this requires that the data be completely hierarchical,
The degree of freedom of the data structure of the database is reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a specific communication terminal device in a communication system in which a server device and a communication terminal device are intermittently connected, such as HTTP. The server device can recognize that all data transmitted by multiple transmissions from the server is data from the specific communication terminal device, and the server device and the communication terminal device perform continuous processing. It is an object of the present invention to provide a data transmission method and a data transmission system capable of performing the same processing as in the case of performing the same.

The accumulated information will be described later in detail.

More specifically, the database access unit 11a transmits the reserved item transmitted from the communication terminal device 20 so as to allow the user of the communication terminal 20 to perform more detailed designation. As for the related information, more detailed selectable items are stored in the database 4.
Search from 0. For example, when a specific selection item of “sports facility A” is transmitted from the communication terminal device 20, the database access unit 11a performs “sports facility A” on the “sports facility A” with respect to “sports facility A”. Are retrieved from the database 40. When a request for reservation processing is first made from the communication terminal device 20, the database access unit 11a searches the database for selectable items for predetermined reservation items.

More specifically, the option creating unit 11b creates an input screen that displays, as options, more detailed selectable items obtained through the database access unit 11a. For example, in the case where the reservation item “Sports facility A” is transmitted from the communication terminal device 20, a group of sports events that can be performed in “Sports facility A” from the database 40 via the database access unit 11 a Is obtained, an input screen as shown in FIG. 2 (b) is displayed in which the sports item group is displayed as options.

The communication control unit 12 controls transmission and reception of data to and from the communication terminal device 20 via the communication line 50. The communication control unit 12 displays the result of processing by the processing unit 11, that is, an input screen displaying the created options. And an accumulated information returning unit 1 for returning accumulated information transmitted from the communication terminal device 20.
2a. The information storage unit 13 stores the communication terminal device 2
0 and the accumulated information with the fixed information added thereto, which is transmitted from
The information is stored in association with the D information. Specifically, the reservation items included in the accumulated information are stored in a predetermined management table together with the ID information. The stored information is registered in the database 40. The information storage unit 13 may be provided in the database 40.

The communication terminal device 20 includes a cumulative information creation unit 2
1, a communication control unit 22, an ID information adding unit 23, and a confirmed information adding unit 24, which are connected to a CRT 25, a touch panel 26, and a keyboard 27. The cumulative information creation unit 21
This is a section for creating new cumulative information by adding new information to the cumulative information. As described above, one or more selection items returned from the cumulative information returning unit 12a of the server device are selected by the communication terminal. And a selection item adding unit 21b for adding the selected selection item as new information to the accumulated information to create new accumulated information. Selection item indicating section 21
Specifically, the selection instruction in the communication terminal device 20a is transmitted to the communication terminal device 20 via the touch panel provided on the front surface of the CRT 25, as shown in FIG.
This is done by pressing by the user.

The ID information adding section 23 adds ID information relating to the communication terminal device 20 to the accumulated information. This ID information is input by a user of the communication terminal device from a keyboard connected to the communication terminal device 20. Also, here is the ID
It is assumed that password information is also added to the information. The fixed information adding unit 24 adds fixed information to the accumulated information to which the ID information is added. The instruction of the confirmation information is also made by the user of the communication terminal device 20 pressing the screen of the CRT 25 having the display for instructing the confirmation transmitted from the server device 10 via the touch panel.

The database 40 stores information related to reservations, specifically, reservable facilities, time zones, and the like. Here, the database 40 stores reservation information on sports facilities. The data structure of the database 40 does not need to be hierarchical, and a data group having some attribute may be stored at random. Further, the storage contents of the database are updated each time the reservation process is completed. Here, the database is provided inside the LAN, but it may be connected via a public communication line, or a plurality of databases 40 may exist.

The database processing device 30 receives an instruction from the database access unit 11a of the server device 10, searches predetermined information from the database 40,
The result is transmitted to the database access unit 11a. The communication line 50 is a public line.
Although an N-switched line is used, the present invention can be similarly implemented using a public telephone line GSTN.

Next, the server device 10 and the communication terminal device 20
A description will be given of the accumulated information transmitted and received between and. Here, HTTP is used as a communication protocol,
It is assumed that the accumulated information is accumulated in a URL (Uniform Resource Locater). First, the server apparatus 10 creates a screen as shown in FIG.
HTML (Hyper Text Markup Lang) as shown in (a)
uage) and sends it to the communication terminal device 20. This sentence, for example, in the first line, when “sports facility A” is selected, the program (prog1) of the server device 10 (the domain name is “xxx”)
Means that a value obtained by substituting the number “1234” into the parameter “sisetu” is transmitted. Further, the program (prog1 or the like) of the server device 10 is set to perform processing such as extracting information related to the transmitted number from the database 40 and creating a selection screen. HTML as shown in FIG.
CRT 25 connected to communication terminal device 20 that received the sentence
Displays a selection screen as shown in FIG.

Here, assuming that the user of the communication terminal device 20 selects and instructs "sports facility A" via the selection item designating unit 21a, the selection item adding unit 21b sets "sisetu".
And the accumulated information transmitting unit 22 a transmits the number to the server device 10. At this time, the above processing is achieved by transmitting a URL including the selected information. "Si" in the transmitted URL
"setu = 1234" is input to the program (prog1) which constitutes a part of the processing unit 11 of the server device 10, whereby the database access unit 11a sets "sisetu"
= 1234 ”and the database 40 returns“ sisetu =
1234 ", here" Sports Facility A "
Search for a group of events available in. Where "sisetu = 12
34 "represents" sports facility A "in the database. When the item group is acquired from the database, the option creating unit 11b creates an HTML sentence shown in FIG. 3B that displays a screen as shown in FIG. 2B. All the HTML sentences include "sisetu = 1234" transmitted by the communication terminal device 20.

In the same manner, the information selected by the communication terminal 20 is added to the URL and
And the selected information is directly written on the URL from the server device 10 and returned to the communication terminal device 20. Thus, the communication terminal device 2 is displayed on the URL.
The information selected by 0 is accumulated to form accumulated information as a result.

The server device and the terminal device having the above configurations can be achieved by incorporating a program that operates on a general computer to achieve the above functions. This program can be recorded on a recording medium such as a floppy disk which can be read by the computer. Further, in the present embodiment, a predetermined program is installed in the server device 10 to achieve the function of the server device, and the server device 10
By transmitting a command to cause the communication terminal device 20 to perform the above-described operation to the communication terminal device 20, the communication terminal device 20 achieves the above-described function, thereby enabling the communication system. It can be realized only by a program incorporated in the computer to be configured.

From this viewpoint, when the server device 10 is captured, it can be considered that the processing unit 11 has a portion for creating an instruction to the communication terminal device 20. That is, the processing unit 11 further includes, as a functional block, an information transmission request creation unit that creates an information transmission command for requesting the communication terminal device to transmit new accumulated information obtained by adding new information to the accumulated information; ID related to the communication terminal for the communication terminal device
ID for creating an ID information transmission command that requests information transmission
An information transmission command creation unit, a determination information transmission command creation unit that creates a determination information transmission command for requesting the communication terminal device to transmit determination information indicating that the cumulative information is determined, and a communication terminal It is also possible to have a return request command creating section for creating a return request command for requesting the device to return the accumulated information.

The operation of the communication system having the above configuration will be described below. FIG. 4 is a sequence diagram showing the operation of the communication system. With reference to this figure, an operation for performing a reservation process for a sports facility will be described. First, the communication terminal device 2
A communication line is connected to the server device 10 from the 0 side, and a request for a sports facility reservation process is made to the server device 10 [1]. Then, the database access unit 11a of the server device 10 searches and obtains available sports facilities from the database, and based on this, the option creating unit 11b
A selection screen as shown in FIG. 2A is created [2], and the communication control unit 12 returns the selection screen to the communication terminal device 20 [3]. At the end of this operation, the server device 10 becomes the communication terminal device 2
Disconnect the line with 0.

Next, the user of the communication terminal device 20 receiving the selection screen shown in FIG.
Press the touch panel on the front of the RT 25 to select it [4]. Here, it is assumed that "sports facility A" (a1) has been selected. Then, as a result of this selection, the server device 10 is specified as the link destination in the URL as shown in FIG.
"Sports facility A" selected with the 0 line connected
(A1) is transmitted to the server 10 [5]. The server device 10 which has received the information obtains the available sports events from the database 40 in the "sports facility A" (a1) by the same operation as described above, and
A selection screen as shown in (b) is created [6]. In addition,
Server device 10 that has received "sports facility A" (a1)
Then, the communication terminal device 20 that transmitted the selection screen in [3]
It cannot recognize that the communication terminal device 20 which transmitted "sports facility A" (a1) is the same as the communication terminal device 20. This is the same throughout the following processing.
The server device 10 displays the created selection screen on the communication terminal device 2
0, and at this time, information for specifying the selected "sports facility A" (a1) is also transmitted as an option [7]. Here again, the communication line is disconnected.

Further, the communication terminal device 20, which has received the selection screen and the information representing the "sports facility A" (a1) as the accumulated information, also operates as shown in FIG.
From the selection screen of (b), one item to be reserved is selected [8]. Here, it is assumed that "tennis" (b2) has been selected. Then, the line is connected again, and this "tennis"
As a result, (b2) is added to "sports facility A" (a1), which is cumulative information, and transmitted to the server device [9]. The server device 10 that has received the accumulated information,
Detailed reservation items relating to the new information "tennis" (b2) in the accumulated information, here selectable dates and times, are obtained from the database 40 in the same manner as described above, and FIG.
[10] is created. Then, the server device 10 transmits to the communication terminal device 20 the accumulated information including the information indicating "sports facility A" (a1) and "tennis" (b2) transmitted from the communication terminal device 20 together with the selection screen. [11]. Here, the communication line is disconnected.

Then, in the same manner as described above, the communication terminal device 20 that has received the accumulated information and the selection screen displays, for example, one of the reservation items “12/2 am9: 00 to 00” from the selection screen.
11:00 "(c1) is selected [12], and the selected item (c1) is further added to the accumulated information and transmitted to the server 10 [13]. Now, assuming that the selection of the reservation item has been completed, the server device 10 that has received the accumulated information sends the ID information of the communication terminal device 20 to the communication terminal device 20 as shown in FIG. An ID information input screen for requesting transmission is created and transmitted to the communication terminal device 20 together with the received accumulated information [14]. Here, the personal identification number is transmitted together with the ID information. Here, the communication line is disconnected again.

The user of the communication terminal device 20 having received the accumulated information and the ID information input screen inputs a user number as ID information and a password on the ID information input screen using the keyboard 27 [15]. . The ID information and the like are added to the accumulated information by the ID information adding unit 23.
Written to RL. Then, the communication terminal device 20
The added cumulative information such as the ID information is transmitted to the server device 10 through the communication line to be connected again [1.
6] Disconnect the line.

The server device 10 that has received this transmission requests transmission of the confirmation information (d) indicating that the accumulated information has been confirmed, that is, as shown in FIG. An information input screen is created and transmitted to the communication terminal device 20 together with the received cumulative information with the ID information added [17]. The reservation information input screen also displays the reservation items selected so far, and the communication terminal 2
The user 0 can confirm the reservation item.

The user of the communication terminal device 20 that has received the confirmation information input screen and the accumulated information presses the “confirmation” portion on the screen via the touch panel 26 if there is no error in the reservation item, and Confirm. As a result, the fixed information (d) is added to the accumulated information via the fixed information adding unit 24 [18]. Specifically, the confirmation information (d) is eventually added to the URL. Then, the communication terminal device 20 transmits to the server device 10 cumulative information having all the reservation items to which the ID information and the fixed information (d) are added [1].
9]. The server device 10 that has received the accumulated information stores the reservation items included in the accumulated information in the information storage unit 13 together with the ID information in the management table [20]. Also,
The stored information is registered in the database 40.

As described above, even if the line between the server device 10 and the communication terminal device 20 is intermittent, the cumulative information stores the history of the reservation items selected by the communication terminal device 20 so far. If the ID information related to the communication terminal device 20 is associated with the final history information in order to make a round trip between the communication terminal device 10 and the communication terminal device 20, the server device 10 selects the reservation item for each communication up to that time. Terminal device 2
By recognizing the identity of 0, the same reservation processing result as when the communication state between the server device 10 and the communication terminal device 20 is maintained can be obtained.

In the above-mentioned processing, finalized information is input at the end. However, this is because the user of the communication terminal device 20 indicates that the accumulated information is final. The server device 10 can recognize that the accumulated information is final based on the finalized information. That is, it is necessary that the ID information is added to the final accumulated information at a minimum. That is, I
If the D information is added to the accumulated information from the communication terminal device 20 at the beginning of the process, the server device 10 can recognize the identity of the communication terminal device 20 for each communication. In this case, if the ID information is deleted only for the final accumulated information, the purpose of storing all the reservation items in association with the ID information cannot be achieved. Conversely, how to add the ID information However, as long as the ID information is added to the final accumulated information, such an object can always be achieved.

Although the ID information and the confirmation information are separate here, they can be shared, and if the ID information is simultaneously the confirmation information, the ID information is added. When the accumulated information is transmitted, the server device 10 regards the accumulated information as final and stores it in the information storage unit 13 together with the ID information.

Further, the ID information is input by the user of the communication terminal. For example, since the address of the transmission source is always transmitted on the Internet, it is possible to use this address and the like as the ID information. is there. And here, the communication by HTTP was explained,
This is not limited to HTTP, and the server device 1
It is needless to say that the present invention can be applied to all communication systems using a communication system in which the communication terminal 0 and the communication terminal device 20 are intermittently connected.

In the above embodiment, the accumulated information is U
Although the information is accumulated in the RL, it is not necessary to accumulate the information in the URL. It is sufficient if the information is accumulated in some form and goes back and forth between the server device and the communication terminal device. The information may be stored in a special portion provided, and the information may be reciprocated between the server device and the communication terminal device.

In the above-described embodiment, the case of facility reservation has been described. However, the present invention can naturally be applied to conference room reservation, book reservation, and the like. Can be used for all processing that needs to recognize the information transmitted and received by the server device a plurality of times from the communication terminal device together with the ID information of the communication terminal device. It can also be applied to processing such as member registration.

[0043]

As described above, the present invention has the following effects. First, in the data communication method according to the present invention, in the information transmission step, new information is further added to the accumulated information returned from the communication terminal device to the server device in the information return step, and the accumulated information is returned in the information return step. The server device that has received the information performs a process related to the added new information, and returns the result of the process and the accumulated information transmitted in the information transmitting step to the communication terminal device. Therefore, the information added to the communication terminal device in the information transmitting step is accumulated as accumulated information by being returned as it is in the information returning step. That is, the history of the information added by the communication terminal device is recorded in the accumulated information. Then, further, in the confirmation information transmitting step, the accumulated information and the information for confirming the accumulated information from the communication terminal device to the server device, and the ID related to the communication terminal device
The server that has received the information and the information for determining the accumulated information in the confirmed information receiving step stores the accumulated information and the ID information in association with the accumulated information as determined.

By such an operation, even if the connection between the server device and the communication terminal device is intermittent,
The information added by the communication terminal device can be recognized and stored on the server device side as the information added by the communication terminal device, and as a result, the processing in the server device is simulated as a series of processes. It can be organically related. In other words, in a communication system in which communication lines are intermittently connected, it is possible to cause the communication line to perform the same processing as a communication system without interruption during a plurality of times of information exchange.

On the other hand, since the communication between the server device and the communication terminal is disconnected when unnecessary, the total time for occupying the communication line is saved compared to the entire time until the accumulated information is determined. This makes it possible to reduce line congestion even when a communication system in which a large number of communication terminals are installed is constructed, so that the line capacity of the server device can be reduced.

Further, in the data communication method of the present invention, in the information return step, a search based on the new information added and creation of an option based on the search result are performed. If the new information in the information transmitting step is the selection information of the option transmitted in the information returning step, the data input of the user of the communication terminal device becomes simple, and the new information is returned. Is very easily added to the accumulated information.

Then, in the data transmission system according to the present invention, the accumulated information creating means of the communication terminal device creates new accumulated information by adding new information to the accumulated information, and the accumulated information transmitting means transmits the accumulated information. Send to server. Then, the processing unit of the server device performs a predetermined process related to the new information included in the cumulative information transmitted from the communication terminal device, and the cumulative information returning unit, together with the result of the process by the processing unit, The accumulated information transmitted from the communication terminal device is returned to the communication terminal. By repeating this, new information added by the communication means to the accumulated information is accumulated as a history. Then, the ID information adding means of the communication terminal means adds ID information relating to the communication terminal to the accumulated information, and the confirmed information adding means further adds decided information to the accumulated information to which the ID information is added.
Then, the information storage means of the server device stores the accumulated information to which the ID information and the fixed information transmitted from the communication terminal device are added in association with the ID information.
