In this figure, reference numerals 1 to 3 denote terminals owned by the user, 1 is a personal computer, 2 is a TV type terminal such as an information home appliance, and 3 is a mobile phone connectable to the Internet. A provider 5 connects the personal computer 1 and the TV terminal 2 to the Internet 7. A provider 6 connects the mobile phone 3 to the Internet 7. Reference numeral 8 denotes an XX company, a WWW (World Wide Web) server 9 and a terminal identification DB (database) server 10
have. Then, in the WWW server 9, a homepage for a personal computer and a TV type terminal 12, a homepage for a TV type terminal 13, a homepage for a mobile phone 14
Are respectively formed, and the terminal identification DB server 10
Is connected to the Internet 7 via providers 5 and 6.

In such a configuration, when the user tries to view the homepage of the company xx from the personal computer 1, first, a browser is started up, and the URL (Uniform Resource Locator) of the homepage of the company xx is obtained. HTTP
//www.xxx.com ". When this URL is input, HTTP_USER_AG of the HTTP protocol
By ENT (User-Agent or the like), data indicating that the source terminal is a personal computer is added to the HTTP protocol, and the terminal identification DB server 10 is accessed via the provider 5. The terminal identification DB server 10 receives this access, detects that the access source is a personal computer from HTTP_USER_AGENT, and connects the access to the homepage 12 of the WWW server 9. Thereby, the homepage 12 is transmitted to the personal computer 1.

When the user attempts to view the homepage of the company XX from the TV terminal 2, the browser is started and the URL “http // www.
× xxx.com ". When this URL is entered,
HTTP_USER_AGENT of HTTP protocol
(User-Agent or the like) adds data indicating that the source terminal is a TV-type terminal to the HTTP protocol, and accesses the terminal identification DB server 10 via the provider 5. Upon receiving this access, the terminal identification DB server 10 detects that the access is a TV type terminal from HTTP_USER_AGENT, and connects the access to the homepage 13 of the WWW server 9.

Similarly, when the user attempts to view the homepage of the company XX from the mobile phone 3, the browser of the mobile phone is started and the URL of the homepage of the company XX is opened.
When "HTTP // www.xxx.com" is entered, the HTTP_USER_AGENT (User-Agent
Etc.), data indicating that the source terminal is a mobile phone is added to the HTTP protocol, and the provider 6
Access to the terminal identification DB server 10 is performed. The terminal identification DB server 10 receives this access,
From the HTTP_USER_AGENT, it is detected that the access is through a mobile phone, and the access is connected to the homepage 14 of the WWW server 9.

The difference between the second embodiment and the first embodiment is the function of the terminal identification DB server 10, and this point will be described in detail below. First, as is conventionally known, the provider 5 or 6 adds the source IP address of the provider when connecting to the Internet 7 from an access from a terminal. In the second embodiment, this source IP address is used.
That is, the terminal identification DB server 10 associates in advance, for each source IP address of a provider, a terminal type generally used by the provider. Then, when there is an access via the provider 5, it is determined from the source IP address of the provider 5 that the terminal is either a personal computer or a TV type terminal, and the access is connected to the homepage 12. When an access is made via the provider 6, the terminal is determined to be a mobile phone from the source IP address of the provider 6, and the access is connected to the homepage 14.

As described above, according to the second embodiment, the terminal type is determined from the source IP address of the provider, and an access connection is made. Generally, the provider of the portable terminal is different from the provider of the personal computer (or TV-type terminal), and thus the above-described terminal determination is possible. However, in many cases, the provider of the personal computer and the provider of the TV-type terminal are common, and therefore, unlike the above-described first embodiment, it is not possible to distinguish whether the terminal is the personal computer or the TV-type terminal. However, what actually poses a problem is the distinction between a portable terminal and a personal computer (or a TV-type terminal) whose display screen sizes are greatly different. It can be said that it is large.

The domain name of the provider may be used instead of the source IP address of the provider. That is, in this case, the terminal identification DB server 10 searches for the source IP address from the domain name of the provider, and determines the terminal type based on the searched source IP address.

Next, a third embodiment of the present invention will be described. FIG. 2 is a block diagram showing the configuration of the Internet system according to the embodiment. 1 is different from the embodiment shown in FIG. 1 in that the terminal identification DB server 10 provided for each company in FIG. 1 is replaced by a terminal identification DB center 16 contracted by a plurality of companies outside the company.

Advertise information (eg, “01”) to the user.

If the user of the personal computer 1 wants to access the homepage of the company XX, he first inputs the URL "www.xxx.com" of the terminal information DB center 16. When the URL is input, data indicating that the source terminal is a personal computer is added to the HTTP protocol by HTTP_USER_AGENT (User-Agent or the like) of the HTTP protocol, and the access data is transmitted via the provider 5 to the terminal identification DB center 16. Sent to The terminal identification DB center 16 receives the access data, transmits the home page of the terminal identification DB center 16 to the personal computer 1, and also transmits the HTTP_USER_AGEN.
From T, the terminal is identified as a personal computer. The personal computer 1 displays a home page of the terminal identification DB center 16.

The user inputs search information “01” of xx company on the displayed homepage. When the search information “01” is input, the terminal identification DB center 16
Detects that it is an access to the xx company based on the search information "01", and xx registered in advance therein
HTTP_US from the URL of the company homepage
URL of homepage 12 corresponding to terminal type “PC” identified based on ER_AGENT “www. ×
* .Com ", and connects the access from the user to the URL.

As described above, in the above-described third embodiment, the terminal identification DB center 16 identifies the type of the source terminal based on the HTTP_USER_AGENT of the HTTP protocol, and sends the Internet 7 to a homepage that matches the identified type. Connect user access through. Note that the search information “01” specifying the xx company
Is not limited to numbers, and various things such as alphanumeric characters, telephone numbers, and kanji can be used.

Next, a fourth embodiment of the present invention will be described. The block configuration of the fourth embodiment is the same as that of FIG. The difference between the fourth embodiment and the third embodiment is the function of the terminal identification DB center 16. That is, the terminal identification DB center 16 preliminarily associates a terminal type generally used by the provider with each source IP address of the provider. And
If there is access to the company homepage via the provider 5, it is determined from the source IP address of the provider 5 that the terminal is either a personal computer or a TV-type terminal, and the xx registered in advance inside The URL of the homepage 12 is read from the URL of the homepage of the company, and the access from the user is connected to the URL. When an access is made via the provider 6, it is determined from the source IP address of the provider 6 that the terminal is a mobile phone, and the access is sent to the homepage 14
Connect to

Note that a source IP address may be searched for from the domain name of the provider instead of the source IP address of the provider, and the terminal type may be determined based on the searched source IP address.

Next, a fifth embodiment of the present invention will be described. FIG. 3 is a block diagram showing the configuration of the Internet system according to the embodiment. This embodiment is an embodiment relating to distribution of electronic mail transmission destinations. In the figure, reference numerals 21 and 22 denote personal computers and mobile phones owned by the user A, 23 denotes a provider to which the personal computer 21 is connected, and 24 denotes a provider to which the mobile phone 22 is connected. Reference numerals 25 to 27 denote personal computers, personal computers, and mobile phones owned by the user B, who is an acquaintance of the user A.

In this terminal identification DB server 33, an e-mail address of each contract user is registered in advance for each terminal. For example, the email address of the user B is registered as follows. Incoming mail address Source terminal Destination mail address PC ＠ PC PC ＠ ○ PC PC mobile phone mobile ＠ × ユ ー ザ 通知 通知 ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ ユ ー ザ. ing.

In such a configuration, when the user A sends an electronic mail to the user B by the personal computer 21, the user A first sets up a mailer, inputs a mail text, and then sends the user B's mail address "PC @@". "○○". When this mail address is input, the mail transmission protocol Mail_USER_AGENT (X-ma
iler etc.), data indicating that the source terminal is a personal computer is added to the mail header, and the mail data is transmitted to the provider 30 via the provider 23.
The terminal identification DB server 33 of the provider 30 detects that the originating terminal is a personal computer from the data indicating the originating terminal added to the mail header, and if the e-mail address is "PC @ xxx" and the originating terminal is If the destination is a personal computer, the destination e-mail address "PC @ XX" or "PC @"
Is read from the internal storage unit, and the received mail is transmitted to one of the read addresses. For example, a personal computer 25
Send an email to

When the user A sends an e-mail to the user B by the mobile phone 22, the mailer of the mobile phone 22 is started, the mail text is input, and the mail address of the user B "PC @ OO" is input. . When this mail address is input, the mail transmission protocol Mail_U
According to SER_AGENT, data indicating that the source terminal is a mobile phone is added to the mail header, and the mail data is transmitted to provider 30 via provider 23. Terminal identification DB server 33 of provider 30
Indicates that the sender terminal is mobile based on the data indicating the sender terminal added to the mail header, and the destination when the mail address is “PC ＠ XXX” and the sender terminal is a mobile phone The mail address "mobile @ xx" is read from the internal storage unit, and the mail is transmitted to the mobile phone 27 via the provider 32 indicated by the read address.

Next, a sixth embodiment of the present invention will be described. The block configuration of this embodiment is the same as that shown in FIG. This embodiment differs from the fifth embodiment in the function of the terminal identification DB server 33. In other words, the terminal identification DB server 33 according to this embodiment associates in advance, for each source IP address of a provider, a terminal type generally used by that provider. Then, when a mail with the mail address “PC @ OO” is received via the provider 23, it is determined from the source IP address of the provider 23 whether the source terminal is a personal computer or a mobile phone. If the received mail address is "PC @ XXX" and the originating terminal is, for example, a personal computer, the destination mail address "PC @ xxx" or "PC @" is read from the internal storage unit and read. Send the received mail to one of the addresses. For example, an e-mail is transmitted to the personal computer 25. If the sender terminal is a mobile phone, the e-mail address is "PC
When the originating terminal is a mobile phone, the destination mail address "mobile @ xx" is read from the internal storage unit and the mail is transmitted to the mobile phone 27 via the provider 32 indicated by the read address. I do.

The above-described sixth embodiment is also similar to the above-described second embodiment.
As in the first embodiment, it cannot be distinguished whether the source terminal is a personal computer or a TV type terminal. However, a portable terminal or a personal computer (or a TV type terminal) can be distinguished, and the practical effect is great. In the fifth and sixth embodiments,
Although the terminal identification DB server 33 is provided inside the provider 30, it may be provided independently of the provider.

[0029]

As described above, according to the first and third aspects of the present invention, the originating terminal is configured to determine the originating source based on the data indicating the type of the originating terminal added to a part of the data transmission protocol. Since the type of the terminal is identified and the access from the source terminal is distributed to the homepage corresponding to the identified type, the size of the user terminal can be determined without considering the size of the screen of the terminal owned by the user. The effect that the homepage most suitable for the screen can be accessed is obtained.

According to the second and fourth aspects of the present invention, the type of the source terminal is identified based on the source IP address of the provider who connected the source terminal to the Internet, and the type corresponding to the identified type is identified.
