Reference numeral 310 is keyword data. Keyword data 3
10 includes a plurality of keywords. 400
Is a keyword management table, which manages the number of appearances of keywords included in keyword data. Upon receiving the keyword data 310 from the keyword server 200, the mobile terminal 100 updates the keyword management table 400 by the keyword update process 520. Further, 300 is the received data. Received data 300
Is, for example, the received e-mail or HTML (Hype
Data described in rText Markup Language). In the mobile terminal 100, the number of appearances of the keyword in the keyword management table 400 is updated by the keyword search process 510 using the received data 300. Further, reference numeral 410 denotes transmission data, which is an electronic mail or HTTP (HyperText Transfer).
An HTTP request message used in Protocol). Reference numeral 210 denotes another device, such as an HTTP server or another mobile terminal. In the mobile terminal 100, the keyword addition process 530 adds a keyword having a large number of appearances to the transmission data 410 and sends it to the other device 210.

These details will be described below.

First, the hardware configuration of the portable terminal 100 will be described with reference to FIG. In the figure, 101 is a CP
U is responsible for controlling peripherals, executing various programs related to data processing and communication. A storage unit 102 is, for example, a ROM (Read Only Memory).

For example, LCD (Liquid Crystal Dis
play) and software for controlling it. A communication device 105 is, for example, a wireless circuit of a mobile phone and software for controlling the wireless circuit.

Next, the keyword management table 400 will be described with reference to FIG. The keyword management table 400 is composed of a plurality of keyword management records 410. Also, one keyword management record 410
Is composed of a keyword 411 and the number of appearances 412. The keyword 411 is a character string serving as a keyword. The appearance count 412 is an integer value that stores the number of appearances of the keyword 411.

Next, the structure of the keyword data 310 received from the keyword server 200 that manages keywords will be described with reference to FIG.

The keyword data 310 is composed of one or more keywords 311. The keyword 311 is a character string representing the keyword.

Next, the keyword updating process 520 will be described with reference to FIG. The keyword updating process may be executed periodically by a timer or may be executed aperiodically. In the keyword update processing 500, first, a keyword request is transmitted to the keyword server 200 (step 501). The keyword request is, for example, HT
TP (HyperText Transfer Pro)
Tocol) is used, HTT like 308a
This is a P request message. Keyword server 20
0 receives the HTTP request message 309a, for example, the HTT including the keyword data 310a.
The P response message 309a is transmitted to the mobile terminal 100. In the mobile terminal 100, this keyword data 3
10a is received (step 502). Next, the keyword management table 400 is initialized (step 50).
3). Specifically, all the keyword management records 410 registered in the keyword management table 400 are deleted. Next, for each of the keywords 311a to 311f included in the keyword data 310a received in step 502, the keyword management records 410a to 410a.
f is created and registered in the keyword management table 400 (step 504). At this time, the keyword 311 of the keyword data is entered in the keyword 411 of the keyword management record, and the number of appearances is set to 0. As a result, 3
If keyword data such as 10a is received, 40
A keyword management table such as 0a is created.

By the keyword updating process described above, the latest keyword can be received from the keyword server 200, and the mobile terminal 100 can always manage only the latest keyword.

Next, the keyword search process 510 will be described with reference to FIG. Keyword search process 510
May be executed when a mail is received or when a home page is viewed, or may be executed periodically or irregularly.

In the keyword search process 510, first, for one of the keyword data 410 registered in the keyword management table 400 (for example, 410a),
The number of the same keywords as the keywords 411a in the keyword data 410a in the received data 300 is counted (step 512). Next, the number counted in step 512 is added to the number of appearances 412a of the keyword data 410a (step 513). For example, 412
When the value of a is 1 and the count in step 512 is 3, the value is set to 1 + 3 = 4. This is performed for all the keyword data 410 registered in the keyword management table 400 (step 511).

FIG. 7 shows an example in which the keyword management table 400 is updated by the keyword search process 510.

It is assumed that the mobile terminal 100 receives the reception data 300a. Further, the state of the keyword management table 400 before the keyword search process 510 is set to 400a. In the received data, the keyword management table 4
There are keywords “Hitachi”, “Mobile”, and “XYZ” registered in 00a. Therefore, the keyword search process 5
10, keyword management data 410a, 410
The number of occurrences 411 of b and 410c is increased by 1, respectively,
The keyword management table looks like 400b.

By the above processing, it is possible to know how many specified keywords appear in the data received by the mobile terminal 100, and to know what information the user of the mobile terminal 100 is interested in. You can

Next, the keyword addition processing 520 will be described with reference to FIG. Keyword addition processing 520
Then, first, of the keyword data 410 registered in the keyword management table 400, some of the keywords having the highest number of appearances 411 are selected in descending order (step 52).
1). Then, the keyword data 410 that frequently appears
The keyword 411 is added to the data to be transmitted (step 522). The method of adding data depends on the transmission procedure (communication protocol) of the data to be transmitted. The communication protocols are HTTP and SMTP (Simple).
MailTransfer Protocol).

Here, a specific example of the keyword addition process 520 will be described with reference to FIG. Here, the state of the keyword management table 400 is as shown in FIG. 3, and step 521 of the keyword addition processing is performed.
The description will be made assuming that the top 3 most frequently appearing ones are selected and processed.

In the figure, reference numeral 410a is an example of data transmitted from the portable terminal 100 to the HTTP server using HTTP. When using HTTP, like 421a in the figure,
In the keyword addition processing 520, a keyword is added to the HTTP header part. Of course, instead of adding the keyword to the header part, it is possible to put it in the URL in the request or add it to another part.

When a keyword is added to the HTTP request message, the HTTP sent by the mobile terminal 100
The server that receives the HTTP request message by using the keyword added to the request message can provide information that the user is interested in by giving priority to information related to the keyword, for example. Becomes

As another example, an example using SMTP will be described with reference to FIG. In the figure, 410a represents the data of the mail to be transmitted. When using SMTP, a keyword is added to the MIME header, such as 421b. It goes without saying that keywords may be added to other parts.

As described above, by adding the keyword to the mail, it is possible to convey to the recipient of the mail what information the user of the sender is interested in by the keyword.

The keyword addition processing of the present invention is performed by H
It is not limited to TTP and SMTP. Mobile terminal 1
00 may be added according to the transmission protocol of the data used.

In the above embodiment, an example in which a keyword is added to the data transmitted from the mobile terminal 100 has been described.
In the following, an example will be described in which the server extracts and manages information regarding the number of appearances of keywords from the mobile terminal 100. By managing the appearance frequency of the keyword in each mobile terminal 100 in the server, it becomes possible to grasp the preference of the user of each terminal.

First, the appearance frequency management table 450 managed by the server in this embodiment will be described with reference to FIG.

As shown in FIG. 11, the appearance frequency management table 450 is a table for managing the appearance frequency of the keyword in each mobile terminal 100. The appearance count management table 450 includes a plurality of appearance count records 460. The appearance count record 460 is the keyword 461.
And the number of appearances 462a-n of the keyword 461 on each mobile terminal 100a-n.

Next, the structure of the keyword appearance information 320 transmitted from the mobile terminal 100 to the server will be described with reference to FIG. The keyword appearance information 320 includes an identifier 321, a keyword 322, and the number of appearances 323. The identifier 321 is information for identifying the mobile terminal 100 or a user who is using the mobile terminal. The keyword 322 is the keyword itself or identification information for identifying the keyword. The appearance count 323 is the appearance count of the keyword indicated by the keyword 322. One keyword appearance information 320 may include a set of a plurality of keywords 322 and the number of appearances 323.

Next, a method of updating the appearance frequency management table 450 will be described with reference to FIG. The process of updating the appearance count management table 450 includes a management table update process 560 in the server and an appearance count information transmission process 550 in the mobile terminal 100. In the management table update process 560, first, a keyword appearance count request is transmitted to the mobile terminal (step 561). Upon receiving the keyword appearance count request, the mobile terminal 100 executes the appearance count information transmission process 550. In the appearance count information transmission process 550, the identifier of the mobile terminal 100 or the identification information of the user who is using the mobile terminal 100 is entered in the identifier 321 of the keyword appearance information 320, and each keyword management record 4 of the keyword management table 400 is entered.
Regarding 10, the keyword 411 is put in the keyword 322 of the keyword appearance information 320, the number of appearances 412 is put in the number of appearances 323, and sent to the server (step 55).
1). In the server, the transmitted keyword appearance information 32
0 is received (step 562). Next, the appearance count management table 450 is updated using the received keyword appearance information 320 (step 563). The update method specifies the appearance count record 460 having the same keyword as the keyword 322 for each of the set of the keyword 322 and the appearance count 323 included in the received keyword appearance information 320, and the appearance count of the appearance count record 460. Number of occurrences 46 identified by the identifier 321 of 462
Update 2. For example, when the identification information 321 is "device 1", the number of appearances 462a corresponding to "device 1" is updated in FIG.

By the above processing, the appearance frequency of the keyword in the plurality of portable terminals 100 can be known in the server. This allows the server to easily understand the preference of the user of each terminal.

In this embodiment, the keyword appearance information 320 is sent from the portable terminal 100 to the server in response to a request from the server. However, the portable terminal 100 uses a timer or the like to periodically or non-periodically enter the keyword appearance information. 320 may be sent to the server. In that case, the process of step 561 becomes unnecessary. In the server, when the keyword appearance information 320 is received, the appearance frequency management table may be updated (step 563).

The server in the above embodiment may be the same as or different from the keyword server 200. Further, although the above description has been made on the premise of the mobile terminal, the present invention is not limited to the mobile terminal. It goes without saying that the present invention can also be applied to so-called information terminals such as personal computers, fixed telephones, and fax machines, which have more resources than mobile terminals.

[0037]

As described above, according to the present invention,
By always acquiring a new keyword from the server, it is possible to manage the keyword efficiently with a small amount of data. Further, since the keywords can be updated, it is possible to always detect fresh keywords. In addition, by managing the keywords included in the information seen by the user and the number of appearances of the information on the mobile terminal side, the keyword having a large number of appearances is sent to the HTTP server so that the information that the user is interested in is presented. Alternatively, by adding a keyword having a high appearance frequency to the mail, it becomes possible to notify the user of the keyword of interest to the sender user.
