A table, a terminal-compatible content ID table, a content data table, and a request log table.

As shown in FIG. 6, the terminal ID table is a table in which a model name of a mobile phone and an ID for identifying the model are stored in association with each other. For example, the terminal ID corresponding to the terminal name “NN20” is “NNN”.

As shown in FIG. 7, the page ID table contains page names such as a request page for requesting content, a request completion page for confirming the completion of the request, and a confirmation page for confirming distribution of the content. , And a table in which the page name of the page name is associated with the page ID. For example, the page ID corresponding to the page name “requested page A” is “abcd”.

As shown in FIG. 8, the terminal compatible page ID table is an ID for identifying data of a page suitable for the terminal, that is, a table for acquiring a terminal compatible page ID from the page ID and the terminal ID. And
This is a two-dimensional table in which a predetermined page ID is described in a row and a predetermined terminal ID is described in a column. Then, a terminal compatible page ID is stored in a portion where the predetermined page ID and the predetermined terminal ID intersect. For example, in FIG. 8, when the page ID is “weff” and the terminal ID is “NNN”, the terminal compatible page ID is “6789”.

The reason that the terminal-compatible page ID table is required is that various pages displayed on the mobile phone are also a kind of content, and as described above, the display 2 of the mobile phone is required.

First, the distribution request source terminal (mobile phone 1) for requesting the distribution of the content is provided by the content request distribution unit 25.
, A request for a distribution request is made (Step 100).
At this time, User-Agent information is also transmitted.

In the content server 3 which has received the request, the page generation processing section 62 generates a content request page (Step 101). In this content request page generation processing, the terminal model of the request source terminal (mobile phone 1) is determined based on the User-Agent information added to the HTTP request. Then, a request page (page for selecting content) corresponding to the determined model is obtained and transmitted to the distribution request source terminal (mobile phone 1).

Upon receiving the request page, the distribution request source terminal (mobile phone 1) displays the request page (Step 10).
2). Then, while confirming the content displayed on the request page, the user inputs the content requested to be distributed and the mail address that can be viewed by the terminal to which the content is distributed (St).
ep 103), requesting distribution of the content (Step 103)
p 104). In this description, the selected content is referred to as “content q” and the destination mail address is “
aaa@bbb.co.jp “and HTTP request”
http: //hostnemae/order.cgi? mail=aaa@bbb.co.jp&cont
ents = contents q ","mail=aaa@bbb.co.jp&contents
= Contents q "is the delivery destination mail address is aaa @ bbb.
co.jp, indicating that the content requested to be distributed is the content q.

In the content server, a content request process is performed by the content request processing unit 63 in response to the distribution request (Step 105). In this content request processing, a unique request ID is generated for each request, and a request log is generated for each request ID. In addition, a mail including the URL (address) of the confirmation page and the request ID which the distribution destination terminal (mobile phone 2) accesses for downloading the content is generated, and this mail is transmitted to the distribution destination terminal (mobile phone 2). The mail address is sent to the mail server 12 as the destination. Further, the request completion page is transmitted to the mail server 11. In addition, distribution destination terminal (mobile phone 2)
"Order = XXX" attached to the e-mail transmitted to the user indicates that the request ID is "XXX".

The distribution request source terminal (mobile phone 1) receives the request completion page and displays the request completion page (Step 106).

On the other hand, in the distribution destination terminal (mobile phone 2), the confirmation mail is received by the e-mail receiving section 24 (Step Ste).
p107), the URL (address) of the confirmation page set in the confirmation mail is accessed by means such as clickable (Step 108). At this time, User-Agent
Information is also sent.

In the content server 3 which has received the request, the content confirmation processing section 64 performs the content confirmation processing (Step 109). In this content confirmation process, the process of confirming the validity of the request and the process of determining the distribution destination terminal (mobile phone 2) are performed by looking at the User-Agent information added to the HTTP request. Further, it acquires the confirmation page data corresponding to the determined terminal and transmits it to the distribution destination terminal (mobile phone 2).

The distribution destination terminal (mobile phone 2) that has received the confirmation page data displays a confirmation page (Step).
110). Then, the contents (model name, etc.) displayed on the confirmation page are confirmed, and a request for downloading the distribution data is made (Step 111).

In the content server 3, a content distribution process is performed by the content distribution processing unit 66 (St).
ep 112). In this content distribution processing, distribution is checked in response to a request for downloading distribution data, and if there is no problem, distribution data suitable for the distribution destination terminal (mobile phone 2) is distributed.

Then, the distribution destination terminal (mobile phone 2) transmits the distribution data (contents q) suitable for the terminal (mobile phone 2).
Is downloaded, and the distribution is completed (Step 113).

Next, page generation processing performed in the content request page generation processing, the content request processing, and the content confirmation processing will be described in detail by taking the operation of the request page generation processing in the content request page generation processing as an example. FIG. 15 is an operation flowchart of a request page generation process in the content request page generation process.

First, the page generation processing section 62 of the content server 3 that has received the request looks at the User-Agent information added to the HTTP request and acquires the terminal name (Step 200). FIG. 15 shows that the acquired terminal name is “NN20”.

Next, the terminal ID corresponding to the terminal name is
Search from the D table (Step 201, Step 2)
02), a terminal ID is obtained (Step 203). FIG. 15 shows that the acquired terminal ID is “NNN”.

Subsequently, a page ID (for example, an ID indicating whether the page is the top page or the next page) assigned to each page in order to obtain the requested page is searched from the page ID table (Step 204, Step 205), and the page is retrieved. An ID is obtained (Step 206). FIG. 16 shows that the page ID is “weff”.

Further, based on the terminal ID and the page ID, a suitable terminal compatible page ID is assigned to the terminal compatible page ID.
(Step 207, Step 208), and obtains a terminal compatible page ID (Step 209). In FIG. 15, the page ID is “weff” and the terminal ID
Is “NNN”, the terminal compatible page ID is “67”.
89 ".

Finally, data of the requested page that matches the acquired terminal compatible page ID is searched from the page data table (Step 210, Step 211), and the requested page data that matches the distribution request source terminal (mobile phone 1) is retrieved. It is acquired (Step 212). Then, the request page data is transmitted to the distribution request source terminal (mobile phone 1) (S
step 213).

In this way, request page data suitable for the requesting terminal (mobile phone 1) can be obtained and transmitted to the requesting terminal (mobile phone 1). Note that the same processing is performed for the page generation processing performed in the other content request processing and the content confirmation processing.

Next, the operation of the content request processing will be described. FIG. 16 is an operation flowchart of the content request processing.

First, the content request processing section 63 of the content server 3 generates a unique request ID for each distribution request (Step 300). FIG. 16 shows that the generated unique request ID is “XXX”.

Next, a mail address of a distribution destination which can be received by the distribution destination terminal (mobile phone 2) is obtained (S).
step 301). FIG. 16 shows that the acquired mail address is “aaa@bbb.co.jp”.

Subsequently, the content ID of the content desired to be distributed is obtained from the name of the content requested to be distributed (Step 302). In this operation, since the desired content is “content q” in FIG.
Indicates that the acquired content ID is “qqqq”.

Then, a request log corresponding to the request ID is generated, and the request ID, the processing status,
The request date and time, the mail address of the distribution destination, the requester terminal ID, and the content ID desired for distribution are recorded (Step
303).

Finally, the e-mail generation unit 66 generates an e-mail including the URL of the request confirmation page and the request ID, and sends the e-mail to the address of the delivery destination (where the mobile phone 2 of the delivery destination can read the e-mail). (St
ep 304). Then, a request completion page is generated by the same operation as the above-described page generation processing and transmitted to the request source terminal (mobile phone 1) (Step 305). This is the end of the description of the operation of the content request process.

Next, the operation of the content confirmation processing will be described. FIG. 17 is an operation flowchart of the content confirmation processing.

When the content confirmation page is accessed based on the electronic mail, the content confirmation processing unit 64 of the content server 3 searches the request log table from the request ID, and retrieves the processing status, request date, and content ID of the corresponding request ID. Acquire (Step 400, Step
p 401).

First, based on the processing status, an unprocessed (0)
Alternatively, it is determined that the processing has been completed (1) (Step 402).

Subsequently, it is determined from the request date and time whether it is within the request expiration date (for example, within three days from the time of the distribution request) (Step 403).

Then, the terminal name of the accessed distribution destination terminal (mobile phone 2) is obtained from the User-Agent information (Step 404). Then, a terminal ID corresponding to the terminal name is searched from the terminal ID table (Step 4).
05, Step 406), and obtain a terminal ID (St.
ep 407). In FIG. 17, the terminal name of the distribution destination terminal (mobile phone 2) is “PP50”, and the terminal name “PP5”.
This indicates that the terminal ID corresponding to “0” is “PPP”.

Next, a terminal compatible content ID corresponding to the acquired terminal ID and the content ID recorded in the request log (the content ID of the content requested to be distributed) is searched from the terminal compatible content ID table. (Step 408, Step 409), a terminal-compatible content ID suitable for the terminal of the distribution destination is acquired (St.
ep 410). In FIG. 17, the terminal ID is “PPP”, and the content ID stored in the request log is “q”.
qqq ”, the terminal-compatible content ID is“ 12
34 ".

Subsequently, the acquired terminal ID, terminal-compatible content ID, and confirmation date and time are additionally recorded in the request log (S
step 411). And the distribution destination terminal (mobile phone 2)
A distribution confirmation page in which the model name and the name of the content to be distributed are described is generated by the same operation as the above-described page generation processing, and the generated distribution confirmation page is transmitted to the distribution destination terminal (mobile phone 2) ( Step 412). This is the end of the description of the operation of the content confirmation processing.

Finally, the operation of the content distribution processing will be described. FIG. 18 is an operation flowchart of the content distribution processing.

As shown in FIG. 9, there is provided a user identifier list table in which a unique identifier for identifying a mobile phone and a user identifier paired with the unique identifier are described in association with each other. In a web interface (HTML) performed via the gateway servers 4 and 5, when a request is received from a mobile phone, the gateway servers 4 and 5 add the request to the mobile phone request using the above-described user identifier list table. The unique identifier to be entered is the user identifier corresponding to this unique identifier (usually
User ID) and forward the request to the content server. Note that, when transmitting a request or the like to the content server 1, the mobile phones 1 and 2 are configured to add a unique identifier for identifying themselves to the request or the like and transmit the request.

Therefore, in another embodiment, a user identifier (User ID) transmitted from the gateway servers 4 and 5 is used.
The ID is used to link the user identifier (User ID) and the request ID, so that terminals other than the authorized destination terminal cannot download the content. The details will be described below.

First, as shown in FIG. 20, a column of a distribution destination user ID in which a user identifier (User ID) of a distribution destination terminal is stored is added to the request log table of the content server 3. Then, at the time of the content confirmation processing, the user ID of the distribution destination terminal (mobile phone 2) is acquired, and the acquired user ID of the distribution destination terminal (mobile phone 2) is described in the request log. Further, in the content distribution process, the user ID of the terminal that has accessed the terminal and the user ID described in the request log are checked, and if they are the same, the distribution process is continued.

That is, Step 410 and Step 410 in the operation flowchart of the content confirmation processing of FIG.
21, that is, a step of acquiring the user ID of the distribution destination terminal (Step 5).
00) is added. Then, in Step 411, the user ID of the obtained distribution destination terminal (mobile phone 2) is also described in the request log.

Further, the user ID corresponding to the request ID is also acquired in Step 500 in the operation flow chart of the content distribution processing of FIG. In addition, Step 5
22 between Step 02 and Step 503, that is, the user I of the terminal (mobile phone) that has accessed
D (Step 600) and a step of comparing the acquired user ID with the user ID stored in the request log (Step 601 and Step 6).
02), and if the acquired user ID does not match the user ID stored in the request log, the content distribution process is stopped (Step 603).

According to such a configuration, terminals other than the authorized distribution destination terminal cannot download the contents, and it is possible to prevent the contents from being unduly spread.

Although the description of the present embodiment is completed above, in the present embodiment, the page generation processing unit 62, the content request processing unit 63, the content confirmation processing unit 64, Although the content distribution processing unit 65 and the e-mail generation unit 66 are provided, these units may be configured by one arithmetic processing unit, for example, a CPU or an MPU. In this case, these CPUs and MPU
Is controlled by a program that performs steps similar to the operations described above. Further, in the present embodiment, a mobile phone is described as an example of a terminal, but the present invention can be applied to any terminal that transmits terminal information such as User-Agent information to a server.
