[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment using the above retrieval system 1 will be specifically described below. (First Embodiment) In the first embodiment, the relay computer 10 searches for an Internet address based on a search keyword of the mobile phone 40, converts the searched Internet address into a specific code, and returns the code to the mobile phone 40. Here are some examples. The processing procedure between the mobile phone 40 and the relay computer 10 in the first embodiment is as shown in the sequence chart of FIG. Here, it is assumed that communication has been established between the mobile phone 40 and the relay computer 10 via the communication company (communication equipment) 30.

A keyword to be searched, for example, "amusement park" is input to the mobile phone 40 through the data input section 44 (K201). The data processing unit 42 causes the communication control unit 41 to transmit the keyword “amusement park” and the terminal information for specifying that the sender is a mobile phone to the relay computer 10. When the transmitted information reaches the relay computer 10 via the communication company 30, the search processing unit 13 performs search condition processing based on the rule table in the storage device 15 (C201). However, when a search condition (and or or the like) is not added (the keyword “amusement park” in this example corresponds to this), the search condition process is passed. Thereafter, the search processing unit 13 collects an Internet address of a homepage corresponding to the keyword “amusement park” based on a database (not shown) in the storage device 15 (C202). For example, "htt
p: //www.aaaaaa.co.jp ". Then, based on the address conversion table 153 in the storage device 15, the address conversion unit 14 converts the Internet address "http://www.aaaaaa.co.jp" as a search result into the simplified code "98".
765 ”(C203). The converted simplified code “98765” is transmitted to the mobile phone 40 through the communication control unit 11.

In the portable telephone 40, the relay computer 10
The transmitted simple code “98765” is received through the communication control unit 41 and is displayed on the browser 43 by the data processing unit 42 (K202). By doing so, it is possible to efficiently display search results even on the mobile phone 40 having a narrow display screen and a limited amount of display information.

(Second Embodiment) In the second embodiment, the relay computer 10
In this example, the Internet address is searched, the searched Internet address is divided, and each divided part is converted into a specific code and returned to the mobile phone 40.

The processing procedure between the mobile phone 40 and the relay computer 10 in this embodiment is as shown in FIG. Here, as in the first embodiment, the mobile phone 4
It is assumed that “amusement park” which is a keyword to be searched is input from the data input unit 44 of “0” (K301). The data processing unit 42 of the mobile phone 40 causes the communication control unit 41 to transmit the keyword “amusement park” and terminal information for specifying that the transmitting terminal is a mobile phone to the relay computer 10. .

When the transmitted information reaches the relay computer 10 via the communication company 30, the search processing unit 13
Then, a search condition process based on the rule table in the storage device 15 is performed (C301). However, in the case of the keyword “amusement park” in this example, since the search condition (and or or) is not added, the search condition process is passed here. Thereafter, based on a database (not shown) in the storage device 15, an Internet address of a homepage corresponding to the keyword “amusement park”, for example, “http: //www.aaaaaa.
co.jp "is collected (C302). Address converter 14
Is the Internet address `` http: //www.aaaaaa.co.j
p ”is divided into“ http: // WWW. ”,“ aaaaaa ”, and“ .co.jp ”, and the address conversion rule table 1 in the storage device 15 is divided.
"Http: // WWW." To "123", ".co.jp"
Is converted to "987". As a result, "http: //www.aaaa
aa.co.jp "is converted to" 123aaaaaa987 "(C30
3). The converted search result “123aaaaaa987” is transmitted to the mobile phone 40 through the communication control unit 11.

In the portable telephone 40, the relay computer 10
The transmitted search result “123aaaaaa987” is received through the communication control unit 41, and is displayed on the browser 43 by the data processing unit 42 (K302). This makes it possible to efficiently display search results on a narrow display screen, as in the case of the first embodiment.

In the first and second embodiments, the transmission of search results from the relay computer 10 to the mobile phone 40 is performed by setting the upper limit of the number of characters for displaying search results on the mobile phone 40 in advance. Can be controlled. In this case, the search result display condition, which is the above condition, is transmitted from the mobile phone 40 as terminal information. The relay computer 10 stores the search result display condition in the storage device 15. The search result display condition in the example of FIG.
The number of search and display at one time is two. Even if more than two Internet addresses can be collected by the search, only two Internet addresses are transmitted to the mobile phone 40 at one time. By doing so, it is possible to display the search results more efficiently.

Further, when transmitting a search keyword from the mobile phone 40 to the relay computer 10, the user arbitrarily specifies whether to display the search result in advance using an Internet address or a converted simplified code, and specifies the search result. Search results can be displayed in a customized format.

(Third Embodiment) In a third embodiment, the search result displayed on the browser 43 of the mobile phone 40 is displayed on the mobile phone 4.
An example in which the relay computer 10 selects a user 0, converts it to an Internet address based on the selected search result, collects homepage information from the converted Internet address, and sends it back to the mobile phone 40 will be described.

The processing procedure between the mobile phone 40 and the relay computer 10 in this embodiment is as shown in FIG. The user of the mobile phone 40 obtains one search result “123aaaaaa987” from the search results displayed on the browser 43.
Is selected (K401). The data processing unit 42
The communication control unit 41 transmits the selected search result “123aaaaaa987” and terminal information for identifying that transmission is being performed by the mobile phone to the relay computer 10. When the transmitted information reaches the relay computer 10 via the communication company 30, the address conversion unit 14
The search result “123aaaaaa987” from the mobile phone 40 is divided into “123”, “aaaaaa”, and “987”, and the storage device 15
"12" based on the address translation rule table 154 in the
"3" to "http: // www." And "987" to "co.jp". As a result, "123aaaaaa987" is converted to the original Internet address "http://www.aaaaaa.co.jp" (C401).

The data processing unit 12 specifies the corresponding information host computer 20 based on the converted Internet address "http://www.aaaaaa.co.jp" and obtains homepage information (C402). . Then, based on the terminal information of the mobile phone 40 obtained earlier, the homepage information is converted so as to be in an optimal form for display on the mobile phone 40 (C403). To the mobile phone 40 via the Internet. The mobile phone 40 receives the home page information transmitted from the relay computer 10 from the communication control unit 41. The data processing unit 42 causes the browser 43 to display the home page information (K402).

In this embodiment and the example, the case where the portable telephone 40 is used as an example of the portable terminal has been described. However, the same effect can be obtained when a portable terminal other than the portable telephone is used. .

According to the present invention, even if the mobile terminal has a limitation in the number of characters, the screen width, the input device, etc. as in a mobile phone, the input and display of the mobile terminal may be hindered if the Internet address is used. It is easy to acquire and display such digital information as described above.

[0031]

As is apparent from the above description, according to the present invention, the input becomes easy even in a portable terminal such as a portable telephone in which it is difficult to input and display the Internet address.
There is a specific effect that information can be displayed appropriately.
