The downloaded image data can be stored in the area 99 of the storage unit 95, and can be displayed again on the display 91 under certain conditions.

  Next, the operation of the embodiment of the present invention having the above configuration will be described. In the description of this operation, a member registration operation for using the image distribution service and an operation of downloading an image to the mobile phone 4 will be described separately.

<Member registration>
In order to use this service, membership registration is first performed.

  FIG. 10 is an operation flowchart showing the member registration operation.

  First, the user of the mobile phone 4 operates the operation unit 96 of the mobile phone 4 to select the site of the IP server 1 to be registered as a member, and transmits an HTTP request (Step 100). FIG. 10 shows that “GET http://IP1.menu.or.jp/uid=xxxxxxx” is transmitted from the mobile phone 4 as an HTTP request. As an example of the above request, “IP1” indicates the IP server 1, “menu” indicates the menu screen for member registration, and “xxxxxxx” of “uid = xxxxxxx” indicates the unique identifier of the mobile phone 4. Yes.

  In the gateway server 2 that has received the request, the user ID corresponding to the unique identifier of the mobile phone 4 is searched from the user ID list table 70, and the unique identifier added to the received request is converted into the searched user ID. It transmits to the IP server 1 (Step 101). In this operation, since the unique identifier added to the request from the mobile phone 4 is “xxxxxxx”, when the user ID corresponding to this unique identifier is searched from the user ID list table 70, the user corresponding to “xxxxxxx” The ID is “abcdefgh”. Therefore, “xxxxxxx” is converted to “abcdefgh” and “GET http://IP1.menu.or.jp/uid=abcdefgh” is transmitted to the IP server 1.

  The IP server 1 extracts “uid = abcdefgh” from the received request “GET http://IP1.menu.or.jp/uid=abcdefgh” and determines whether the corresponding user ID has already been registered. The member list table 31 is searched and collated. If the user ID corresponding to the member list table 31 is not described, an HTML source for member registration is transmitted as a response via the gateway server 2. (Step 102).

  The mobile phone 4 receives the response and transmits a member registration request in accordance with the instruction displayed on the screen (Step 103). For example, it is assumed that “http://IP1.request.or.jp/uid=xxxxxxx” is transmitted as a request from the mobile phone 4. Here, “request” indicates a request for member registration.

  The gateway server 2 receives the request “http://IP1.request.or.jp/uid=xxxxxxx” from the mobile phone 4 and converts the same operation as Step 101 described above, that is, the unique identifier into a user ID. To the IP server 1 (Step 104).

  The IP server 1 receives the member registration request from the mobile phone 4 and newly describes the user ID described in the request, in this example “abcdefgh”, in the member list table 31 to perform the member registration process. (Step 105). Thereafter, a response of member registration completion is transmitted to the mobile phone 4 via the gateway server 2 (Step 106).

Member registration is completed by the above operation.
<Distribution of image data>
Next, the image data distribution operation after member registration will be described.

  FIG. 11 is an operation flowchart showing an image data distribution operation.

  First, the user of the mobile phone 4 operates the operation unit 96 of the mobile phone 4 to select the site of the IP server 1 that distributes images and transmits an HTTP request (Step 200). FIG. 11 shows that “GET http://IP1.channel.or.jp/uid=xxxxxxx” is transmitted from the mobile phone 4 as an HTTP request. As an example of the above request, “IP1” indicates the IP server 1, “channel” indicates the image distribution menu request, and “xxxxxxx” of “uid = xxxxxxx” indicates the unique identifier of the mobile phone 4. ing.

  In the gateway server 2 that has received the request, the user ID corresponding to the unique identifier of the mobile phone 4 is searched from the user ID list table 70, and the unique identifier added to the received request is converted into the searched user ID. It transmits to the IP server 1 (Step 201). In this operation, since the unique identifier added to the request from the mobile phone 4 is “xxxxxxx”, when the user ID corresponding to this unique identifier is searched from the user ID list table 70, the user ID is “abcdefgh”. is there. Therefore, “xxxxxxx” is converted to “abcdefgh” and “GET http://IP1.channel.or.jp/uid=abcdefgh” is transmitted to the IP server 1.

  The IP server 1 searches the member list table 31 for whether or not the user ID “abcdefgh” of the received request “GET http://IP1.channel.or.jp/uid=abcdefgh” has already been registered. To collate (Step 202). In the member registration operation, since the user of the mobile phone 4 has completed the member registration, the user ID is described in the member list table 31. Therefore, an HTML source for image distribution is transmitted as a response to the mobile phone 4 via the gateway server 2.

  The mobile phone 4 receives the response, and transmits a request for requesting distribution of the desired image according to the instruction displayed on the screen (Step 203). For example, it is assumed that “http://IP1.channel.or.jp/chara=new1/uid=xxxxxxx” is transmitted as a request from the mobile phone 4. Of the transmitted requests, “chara = new1” is identification information of an image desired to be distributed, and “new1” indicates the latest image, that is, the image data of the character of the day.

  The gateway server 2 receives the request “http://IP1.channel.or.jp/chara=new1/uid=xxxxxxx” from the mobile phone 4 and performs the same operation as Step 201 described above, that is, assigns a unique identifier to the user. The ID is converted and transmitted to the IP server 1 (Step 204).

  The IP server 1 receives the request from the mobile phone 4, searches the member list table in the same manner as in Step 202, and if it is confirmed that the member is a member, it is based on the identification information of the image data described in the request. The image data stored in the image folder 32 is read out and transmitted to the mobile phone 4 through the gateway server 2 (Step 205). In this operation, since the request is “http://IP1.channel.or.jp/chara=new1/uid=abcdefgh”, the image identification information is “new1”, which is the image data of the current character. The image data is read from today's image folder 321 and transmitted to the mobile phone 4 via the gateway server 2.

  The cellular phone 4 receives the image data, stores the received image data in the VRAM 92, and displays it on the display (Step 206). On the other hand, when the downloaded image data is displayed again, it is stored in the area 99 of the storage unit 95 (Step 207).

  With the above operation, the character image data is downloaded to the mobile phone 4. Even when the downloaded image data is stored, the image data is stored in the storage area controlled by the user, so the stored image data can be sent to another person or newly processed. No acts that infringe on copyrights such as

  A second embodiment will be described.

  There are various types of mobile phones currently on the market, and each has various screen sizes and image data sizes that can be displayed. Therefore, if only one type of image data to be distributed is prepared, it may not be displayed correctly depending on the type of mobile phone, and may not be displayed at all. Therefore, in the second embodiment, image data corresponding to the model of the mobile phone is prepared for the same content, and a function for distributing the image data corresponding to the model is added to the first embodiment. And In the description of the second embodiment, the same reference numerals are assigned to the same components as in the first embodiment, and detailed description thereof is omitted.

  Currently, various services send their model information when sending a request from a mobile phone. Therefore, in the second embodiment, the IP server 1 determines this model information, and selects and distributes image data corresponding to the model. Therefore, as image data to be prepared, as shown in FIG. 12, a folder for each model is prepared in the image folder 32, and image data corresponding to the model is stored in the folder for each model. In FIG. 12, folders from model AAA to model ZZZ are provided, and a folder for each model, for example, a folder for model NNN, a folder for storing image data for the current day, and a folder for back numbers for storing past image data. It is shown that is provided. Similarly, an image distribution menu is prepared for each model.

  The operation in the above configuration will be described below.

  FIG. 13 is an operation flowchart showing an operation of image data distribution by model.

  First, the user of the mobile phone 4 operates the operation unit 96 of the mobile phone 4 to select the site of the IP server 1 that is distributing images, and transmits an HTTP request (Step 300). FIG. 14 shows that “GET http://IP1.channel.or.jp/uid=xxxxxxx user = NNN” is transmitted from the mobile phone 4 as an HTTP request. As an example of the above request, “IP1” is the IP server 1, “channel” is the image distribution menu request, “xxx =” of “uid = xxxxxxx” is the unique identifier of the mobile phone 4, “user = NNN” indicates the model of the mobile phone 4.

  In the gateway server 2 that has received the request, the user ID corresponding to the unique identifier of the mobile phone 4 is searched from the user ID list table 70, and the unique identifier added to the received request is converted into the searched user ID. It transmits to the IP server 1 (Step 301). In this operation, since the unique identifier added to the request from the mobile phone 4 is “xxxxxxx”, when the user ID corresponding to this unique identifier is searched from the user ID list table 70, the corresponding user ID is “abcdefgh”. "It is. Therefore, “xxxxxxx” is converted to “abcdefgh”, and “GET http://IP1.channel.or.jp/uid=abcdefgh user = NNN” is transmitted to the IP server 1.

  In the IP server 1, the member list indicates whether the user ID "abcdefgh" of the received request "GET http://IP1.channel.or.jp/uid=abcdefgh user = NNN" has already been registered. The table 31 is searched and collated (Step 302). In the member registration operation, since the user of the mobile phone 4 has completed the member registration, the user ID is described in the member list table 31.

  Therefore, an HTML source for image distribution for the model NNN is transmitted as a response from the model information “user = NNN” to the mobile phone 4 via the gateway server 2 (Step 303).

  The mobile phone 4 receives the response and transmits a request for requesting distribution of the desired image in accordance with the instruction displayed on the screen (Step 304). For example, it is assumed that “http://IP1.channel.or.jp/chara=new1/uid=xxxxxxx user = NNN” is transmitted as a request from the mobile phone 4. Of the transmitted requests, “chara = new1” is identification information of an image desired to be distributed, and “new1” indicates the latest image, that is, the image data of the character of the day.

  The gateway server 2 receives the request “http://IP1.channel.or.jp/chara=new1/uid=xxxxxxx user = NNN” from the mobile phone 4 and operates in the same manner as Step 301 described above, that is, unique. The identifier is converted into a user ID and transmitted to the IP server 1 (Step 305).

  The IP server 1 receives the request from the mobile phone 4 and searches the member list table in the same manner as in Step 302 (Step 306). If it is confirmed that the user is a member, go to the image folder for the model from the model information, and further read out the image data stored in the image folder based on the identification information of the image data described in the request, and the gateway It transmits to the mobile phone 4 via the server 2 (Step 307). In this operation, since the request is "http://IP1.channel.or.jp/chara=new1/uid=abcdefgh user = NNN", the model information is "NNN" and the image identification information is "new1 "It is. This shows the image data of today's character for the model NNN. The image data is read from the image folder for today of the model NNN and transmitted to the mobile phone 4 via the gateway server 2.

  The cellular phone 4 receives the image data, stores the received image data in the VRAM 92, and displays it on the display (Step 308). On the other hand, when the downloaded image data is to be displayed again, it is stored in the area 99 of the storage unit 95 (Step 309).

  With the above operation, the mobile phone 4 is delivered with image data that is optimal for the model, and the inconvenience that it cannot be displayed depending on the model can be avoided.

  In the second embodiment described above, the model information of the mobile phone 4 is transmitted from the mobile phone 4. However, a table in which the model information of the mobile phone 4 and the unique identifier of the mobile phone 4 are described in correspondence is prepared in the gateway server 2 in advance, and if there is a request from the mobile phone 4, it is added to the request The model information of the mobile phone 4 may be retrieved from the table based on the unique identifier, and the retrieved model information may be added to the request and transmitted to the IP server 1.

  Even with such a configuration, the IP server 1 can obtain the necessary model information of the mobile phone 4, and therefore can select image data suitable for the model of the mobile phone.

  A third embodiment will be described.

  Although it has already been described that mobile phones can send and receive data at present, this can be applied to receive so-called e-mail services. On the other hand, the first and second embodiments described above are so-called pull-type services. Therefore, in the third embodiment, the user is notified of the image information updated every day by e-mail, and the user downloads the latest image data by operating a link set in the received e-mail. And a so-called push-type service system.

  Further, since the third embodiment uses electronic mail, not only the web interface, that is, the HTTP (Hyper Text Transfer Protocol) communication method, but also the mail interface as in the first and second embodiments described above. That is, the SMTP (Simple Mail Transfer Protocol) communication method is also used. Normally, in the SMTP communication method, the gateway server 2 does not add a user ID to an electronic mail. Therefore, special processing is performed to maintain the relationship with the user ID.

  The configuration will be described below. In the description of the third embodiment, the same reference numerals are assigned to the same components as those in the first embodiment and the second embodiment, and detailed description thereof is omitted.

  In the third embodiment, the mobile phone 4 responds to a request from the mobile phone 4 based on the HTTP communication method, and activates the e-mail function of the mobile phone 4 using a function such as a CGI script, for example. Means for creating a mail distribution list of members who wish to distribute e-mails sent from the Internet, and means for notifying members of e-mails described in the mail distribution list based on the SMTP communication method; 1 is provided.

  Furthermore, as described above, since transmission / reception of electronic mail is performed by the SMTP communication method, the IP server 1 cannot obtain a user ID for identifying the user from the electronic mail. Therefore, a means for generating a mail identifier that is paired with the acquired user ID is provided, and the generated mail identifier is set as an email to be transmitted and transmitted.

  These means are realized in the MPU 24 of the IP server 1.

  The operation of the third embodiment will be described below. In the description of this operation, a member registration operation for using the mail delivery service and an operation of downloading an image to the mobile phone 4 will be described separately.

<Mail delivery member registration>
In order to use this service, member registration for mail delivery is first performed.

  FIG. 14 is an operation flowchart showing the operation of mail delivery member registration.

  First, the user of the mobile phone 4 operates the operation unit 96 of the mobile phone 4 to select the site of the IP server 1 to be registered as a member, and transmits an HTTP request based on the HTTP communication method (Step 400). ). FIG. 14 shows that “http://IP1.mail.or.jp/uid=xxxxxxx user = NNN” is transmitted from the mobile phone 4 as an HTTP request. As an example of the above request, “IP1” is the IP server 1, “mail” is the mail distribution member registration menu screen, “uid = xxxxxxx” is “xxxxxxx” is the unique identifier of the mobile phone 4, “user = NNN” indicates the model of the mobile phone 4.

  Since the gateway server 2 that has received the request is a request based on the HTTP general method, the user ID corresponding to the unique identifier of the mobile phone 4 is searched from the user ID list table 70 and the unique identifier added to the received request. Is converted into the searched user ID and transmitted to the IP server 1 (Step 401). In this operation, since the unique identifier added to the request from the mobile phone 4 is “xxxxxxx”, when the user ID corresponding to this unique identifier is searched from the user ID list table 70, the user corresponding to “xxxxxxx” The ID is “abcdefgh”. Therefore, “xxxxxxx” is converted to “abcdefgh”, and “http://IP1.mailmenu.or.jp/uid=abcdefgh user = NNN” is transmitted to the IP server 1.

  In the IP server 1, the mail distribution member list table indicates whether or not the user ID “abcdefgh” of the received request “http://IP1.mail.or.jp/uid=abcdefgh user = NNN” is already registered. Search for 150 and match. FIG. 15 is a diagram showing an example of the mail delivery member list table 150. The mail delivery member list table 150 includes a user ID of a member of the mail delivery service, a member's email address, and a date of membership registration. Corresponding is described for each content. If the corresponding user ID is not described in the mail delivery member list table 150, a member registration request is received from the mobile phone 4, and an e-mail function of the mobile phone 4, such as a mailer program, is obtained by a CGI script or the like. Send the response to be activated. At this time, an identifier having a pair relationship with the extracted user ID “abcdefgh”, for example, “200000504” is generated. Then, the generated mail identifier “200000504” and the mail address possessed by the IP server 1, for example, “mail@IP1.or.jp” are added to the response and transmitted (Step 403).

  The above processing is performed by the HTTP communication method.

  Note that the processing of Step 405 and Step 407, which will be described later, is performed by the SMTP communication method, and thus description of the gateway server 2 is omitted.

  When the mobile phone 4 receives the response, the e-mail transmission / reception function is activated (Step 404). The destination of the e-mail is the mail address “mail@IP1.or.jp” of the IP server 1, and the sender of the mail is the mail address “user@xxx.or.jp” of the user (mobile phone 4). Set to In addition, the received mail identifier “20000204” is also set in the mail to be sent (Step 405). Then, the mail with these settings is transmitted based on the SMTP communication method.

  The IP server 1 receives an electronic mail from the mobile phone 4 and specifies a user ID from the mail identifier “20000504” set in the electronic mail. Furthermore, the user's email address is specified from the email sender "user@xxx.or.jp". As a result, the user ID “abcdefgh” and the mail address “user@xxx.or.jp” are associated with each other and stored (Step 406).

  Next, a site for confirming membership registration is prepared. This confirmation site is set so that only the mobile phone 4 having the user ID associated with the mail address can access. Then, the user's mail address is set as the e-mail transmission destination address, the mail address of the IP server 1 is set as the transmission source, and a member registration confirmation mail is set in which the link destination of the site dedicated to the user ID is set. (Step 407). In FIG. 14, the user's mail address “user@xxx.or.jp” is set as the e-mail transmission destination address, and the mail address “mail@IP1.or.jp” of the IP server 1 is set as the sender. This indicates that “IP1.confirmation1.or.jp” is set as the link destination of the site dedicated to the user ID.

  If the mobile phone 4 receives an e-mail for registration confirmation and registers e-mail delivery, the link button set in the received e-mail is pressed, and an HTTP request based on the HTTP communication method is transmitted (Step 408).

  Since the HTTP request is based on the HTTP communication method, the gateway server 2 that has received the request searches the user ID list table 70 for the user ID corresponding to the unique identifier of the mobile phone 4, and the unique identifier added to the received request. Then, it is converted into the searched user ID and transmitted to the IP server 1 (Step 409). In this operation, since the unique identifier added to the request from the mobile phone 4 is “xxxxxxx”, when the user ID corresponding to this unique identifier is searched from the user ID list table 70, the user corresponding to “xxxxxxx” The ID is “abcdefgh”. Therefore, “xxxxxxx” is converted to “abcdefgh”, and “http://IP1.confirmation1.or.jp/uid=abcdefgh user = NNN” is transmitted to the IP server 1.

  The IP server 1 receives the request and transmits the HTML source of the site (Step 410).

  The mobile phone 4 receives the HTML source and displays it on the screen. If the user wants to register, the user presses an “OK” button displayed on the screen and transmits a member registration request (Step 411). FIG. 14 shows that “http://IP1.confirmation1.or.jp/ok/uid=xxxxxxxx user = NNN” is transmitted as an HTTP request.

  Since the HTTP request is based on the HTTP communication method, the gateway server 2 that has received the request searches the user ID list table 70 for the user ID corresponding to the unique identifier of the mobile phone 4, and the unique identifier added to the received request. Then, it is converted into the searched user ID and transmitted to the IP server 1 (Step 412). In this operation, since the unique identifier added to the request from the mobile phone 4 is “xxxxxxx”, when the user ID corresponding to this unique identifier is searched from the user ID list table 70, the user corresponding to “xxxxxxx” The ID is “abcdefgh”. Therefore, “xxxxxxx” is converted to “abcdefgh” and “http://IP1.confirmation1.or.jp/ok/uid=abcdefgh user = NNN” is transmitted to the IP server 1.

  In response to the request, the IP server 1 registers the stored user ID and mail address as a pair in the mail delivery member list 150 (Step 413).

  Member registration is completed by the above operation.

In this description, in order to carefully check the user's intention to register for mail delivery, the user is linked to a registration confirmation site, and after confirming the intention of registration again, is registered in the mail delivery member list 150. did. However, the registration operation may be terminated when an e-mail from the user is received without confirming the intention of registration again. That is, at Step 406, when the user ID and the mail address are linked in a pair relationship, the mail address and the user ID may be registered in the mail delivery member list 150 as a pair. In this case, the processing after Step 407 becomes unnecessary.
<Distribution of image data>
Next, the image data distribution operation after member registration will be described.

  FIG. 16 is an operation flowchart showing an image data distribution operation.

  First, when an image to be distributed is added, the IP server 1 creates a mail in which a link destination is set so as to read out a folder storing the latest added image data and an image (Step 500). Then, the created mail is broadcasted to the mail addresses described in the mail delivery member list table 150 (Step 501).

  In the cellular phone 4, when a mail is received and a link button set in the electronic mail is pressed, a request is automatically transmitted (Step 502). For example, it is assumed that “http://IP1.channel.or.jp/chara=new1/uid=xxxxxxx user = NNN” is transmitted as a request from the mobile phone 4. Of the transmitted requests, “chara = new1” is identification information of the latest image added, and “user = NNN” indicates the model of the mobile phone 4. The subsequent operations follow the web interface.

  The gateway server 2 receives the request “http://IP1.channel.or.jp/chara=new1/uid=xxxxxxx user = NNN” from the mobile phone 4, converts the unique identifier into a user ID, and converts it to an IP server. 1 (Step 503).

  In the IP server 1, the member list table 31 indicates whether or not the user ID “abcdefgh” is registered from the received request “http://IP1.channel.or.jp/chara=new1/uid=abcdefgh user = NNN”. Are searched and collated (Step 504). In the member registration operation, since the user of the mobile phone 4 has completed the member registration, the user ID is described in the member list table 31. Therefore, the image information stored in the image folder is read based on the identification information of the image data described in the request from the model information, and the mobile phone 4 is connected via the gateway server 2. (Step 505). In this operation, since the request is “http://IP1.channel.or.jp/chara=new1/uid=abcdefgh user = NNN”, the model information is “user = NNN”, and the image identification information is "new1". This shows the image data of today's character for the model NNN. The image data is read from the image folder for today of the model NNN and transmitted to the mobile phone 4 via the gateway server 2.

  The cellular phone 4 receives the image data, stores the received image data in the VRAM 92, and displays it on the display (Step 506).

  On the other hand, when the downloaded image data is to be displayed again, it is stored in the area 99 of the storage unit 95 (Step 507).

  As is clear from the above description, each unit can be configured by hardware, but can also be realized by a computer program. In this case, functions and operations similar to those of the above-described embodiment are realized by a processor that operates according to a program stored in the program memory.

  Although the present invention has been described with reference to the preferred embodiments and examples, the present invention is not necessarily limited to the above-described embodiments and examples, and various modifications can be made within the scope of the technical idea. I can do it.
