The page data of the initial screen (homepage) for the mobile phone 11 is transmitted to the mobile phone 11.

The mobile phone 11 displays the display screen 3f of the home page 39 on the display unit 11a as shown in FIG. Then, a series of processing operations for deleting the site from the bookmark in the content server 19a of the portal site 18 ends.

Next, the features of the embodiment configured as described above will be described below. (1) In the present embodiment, a bookmark is provided in the content server 19a of the portal site 18 for the user of the mobile phone 11. Therefore, for the user of the mobile phone 11, even if the number of sites that can be registered as a bookmark is limited, the content server 19
A large number of sites can be registered by the bookmark a, and more convenient services can be provided to the user from the viewpoint of the portal site 18 having the content server 19a.

(2) In this embodiment, the portal site 1
By providing a bookmark in the content server 19a of FIG. 8, a home page 39 of the user of the mobile phone 11 is automatically created in the content server 19a. Therefore, the user can use the mobile phone 11 more effectively and for multiple purposes. Moreover, the content server 19
From the viewpoint of the portal site 18 that possesses “a”, meaningful content can be provided to the user of the mobile phone 11.

(3) In this embodiment, the portal site 1
The content server 19a of No. 8 provides content only to a specific user. That is, the mobile phone 11 can be used by the mobile phone network 12, and the content server 19a of the portal site 18 can be accessed via the gateway server 14 of the management center 13 connected to the mobile phone network 12. Therefore,
The portal site 18 stores a specific user (the mobile phone network 12
The above-mentioned content can be provided only to a mobile phone 11) that can use the content, and differentiation from other content providers can be achieved.

(4) Moreover, in the present embodiment, the environment variable obtained from the HTTP request is added to the data transmitted from the gateway server 14 to the content server 19a as identification data, and the content server 19a of the portal site 18 transmits the environment variable to the content server 19a. Based on the variables, the user is identified as a specific user, access is allowed, and various contents are transmitted. Therefore, the gateway server 14
Does not need to perform a special processing operation for creating and attaching identification data.

(5) In the present embodiment, when creating a URL for a bookmark of a user (mobile phone 11), the only mail address (source) assigned to each mobile phone is a file name and a file name. URL was created. Therefore, the content server 19a of the portal site 18 can identify the user easily and reliably without overlapping with the URL of the other mobile phone, and the created URL is the mail of the own (mobile phone) for the user. The address is easy to remember and will not be forgotten.

The present invention is not limited to the above embodiment, but may be implemented as follows. In the above-described embodiment, the portal site 18 accesses a search site having a search engine and registers the site obtained by the search as a bookmark. However, the portal site 18 has a search engine and searches using the search engine. You may do so. In this case, link information for linking to the content server 19a of the portal site 18 can be easily added to the page data for displaying the search result.

In the above embodiment, the portal site 18
The content server 19a allows only a mobile phone 11 connected to a gateway server 14 that manages a predetermined mobile phone network 12 as a specific user.

[0100] This can be done by using a personal computer as a portable terminal.
Connect with S (Personal Handyphone System). Then, the personal computer and the server of the Internet connection provider (Internet connection server) are connected via the PHS network and the telephone line network. This Internet connection provider is an Internet connection provider contracted to the portal site 18 in advance. Then, the content server 19a of the portal site 18 can identify whether the personal computer has been accessed through the PHS network and the telephone line network, and permits access if the personal computer has been accessed through the PHS network and the telephone line network. You may make it. In other words, the content server 19a of the portal site 18 may be configured so that a personal computer connected to the Internet connection provider via a predetermined PHS network is also a specific user, and that access to the personal computer is permitted.

In this case, the content server 19a of the portal site 18 determines whether to permit access, for example, as follows. The content server 19a registers in advance the domain name of the contracted Internet connection provider. When there is access from the contracted Internet connection provider, the content server 19a extracts the IP address of the Internet connection provider. The content server 19a performs a so-called "reverse address lookup" for finding a domain name from the extracted IP address. More specifically, the content server 19a inquires a DNS (Domain Name System) server about a domain name for the extracted IP address. When the domain name is transmitted from the DNS server, the content server 19a determines whether or not the domain name matches the domain name of the registered Internet connection provider registered in advance. Then, if they match, access is permitted, and if they do not match, access is not permitted.

In another method, the content server 19a registers the IP address of the contracted Internet connection provider in advance. Then, when there is access via the contracted Internet connection provider, the content server 19a extracts the IP address of the Internet connection provider. The content server 19a compares the extracted IP address with the previously registered IP address and determines whether they match. And
If they match, access is permitted; if they do not match, access is not permitted.

In this case, it is easier than inquiring the DNS server, and the load on the content server 19a is reduced. However, when the IP address of the contracted Internet connection provider is changed, there is a disadvantage that a troublesome work of re-registering the IP address must be performed each time as compared with inquiring the DNS server.

In the above-described embodiment, when a new bookmark is created, a bookmark is added or deleted, a password is input. However, this may be omitted.

In the above embodiment, the mobile phone 11 converts the data for registering the URL of the site into the content server as a bookmark into a mail, and converts the data into a mail.
, The content server 19a creates a URL for the user whose file name is the mail address of the mobile phone 11 from the mail received by the mail server 19b. This may be performed by creating a user URL having a file name other than the mail address.

In the above embodiment, a portable terminal is embodied as a portable terminal, but a PDA (Personal Digital Assis
tant).
