FIG. 7 is a diagram showing a messaging format of a response to be transmitted, FIG. 7 is a diagram showing a messaging format after protocol conversion of the response, and FIG. 8 is a diagram explaining an operation example of the communication system.

First, the direct access link protocol (DALP) is shown in FIG.
As shown in, the bearer service used by the application is set from the beginning, and the bearer identifier in which the direct access service is set and the version of DALP are set to support future version upgrades due to functional extension of the protocol. Protocol version, a DALP identifier in which an identifier for identifying the type of DALP operation in DALP messaging, a type of messaging, etc. is set, and an option for concealing and authenticating data exchanged between a spare and a terminal A key that is an information element, a session number that is a number assigned to identify a messaging session, a sequence number that is a sequence number in a messaging session, and an application that identifies an application. And Deployment identifier comprised of a unit number indicating the number of the unit, and total unit number indicating the total number of units, and the DAS data length indicating the length of DAS data, a checksum for error control.

As shown in FIG. 4, the messaging format of the user request from the mobile station (MS) 11 to the information providing system 70 constitutes a message transfer protocol including a mobile side number (MSN) such as a mobile phone number from the beginning. Advanced ATP (Advanced Messaging Transfer Proto)
col), the above direct access link protocol (DALP), a mobile device profile, and data such as an address of an information provider and a request keyword, and is, for example, 1 kilobyte in total. The mobile device profile is data such as the model code and remaining memory,
Based on this data, the information providing system 70 sends it together with the request, and the screen size, color display or 4-gradation display screen type, model and short sound related to the specifications of the mobile device (MS) 11 are transmitted based on this data. Convert to data such as ringtone type such as 2 chords or 5 chords, remaining memory amount, etc., and the information provider (IP) 22 side downloads the most suitable content for the mobile device (MS) 11 based on the data. It is for. For example, the link of the home page of a certain information provider <AH = "http: www.domain / url? Uid = 1 & sid
= 1234 / "> Contents </A> is a D-type mobile device J-AB
The data when 01 is selected is as follows. M / 2Type = J-AB01? Mem = 256? Http: //www.domain/url? Uid = 1
& sid = 1234?

User request information providing system 70
The messaging format converted by the protocol is
As shown in FIG. 5, the hypertext transfer protocol (HTTP) request method and H
It is composed of TTP header information, a mobile device profile, and a user identification number (UID). The HTTP request method is as follows, for example. GET http: www.domain / url? Uid = 1 & sid = 1234 HTTP / 1.1 <CR
> The mobile device profile and UID are as follows, for example. X-jphone-msname: J-AB01 <CR> X-jphone-display: X * Y <CR> X-jphone-color: CZ <CR> X-jphone-sound: n <CR> X-jphone-uid: 1111111111111111 <CR> Here, X * Y is the number of dots on the screen, Z is the gradation of the color image, and n is the number of chords.

The messaging format transmitted from the information provider (IP) 22 to the information providing system 70 is as follows.
As shown in FIG. 6, the HTTP response header, the HTTP header information, and the response are arranged from the beginning. H
The TTP response header is as follows, for example. HTTP / 1.1 200 OK <CR> The response is as follows, for example. <2><T> Sample </ T> Sample MML <BR></2>

When a request for downloading the contents of the information provider (IP) 22 is made, the mobile unit (M
S) 11, the message communication unit 46 refers to the remaining memory amount data in the mobile unit profile processing unit 57, and the mobile unit profile processing unit 57 sets the model code and the remaining memory as the mobile unit profile to the above user. Organized into a request messaging format, as shown in FIG.
As shown in (), the data is transmitted from the mobile device (MS) 11 to the information providing system 70 via the mass data transfer system 30 (). The information providing system 70 converts the messaging format of the transmitted user request into the above HTTP format messaging format so that it can be recognized by the information providing source (IP) 22 side site on the Web, and then transmits (). At that time, the information providing system 70 refers to the model code and calls data such as the number of dots on the screen, the gradation of the color image, the number of corresponding chords from the model code table and transmits it together with the request. The information provider (IP) 22 that has received the request selects the optimum content from among the patterns of all the mobile device profiles created in advance, or the mobile device (M
S) The optimum content is created corresponding to the mobile device profile transmitted from the 11 side, and is transmitted to the information providing system 70 side as the above HTTP format messaging format (). If the mobile device (MS) 11 includes contents that cannot be displayed as they are,
The information providing system 70 converts the data into optimum data. When the remaining memory capacity of the data of the mobile device profile is smaller than the capacity of the requested content, data indicating that is returned instead of the requested content. The information providing system 70 converts the HTTP format messaging format including the response transmitted from the information providing source (IP) 22 into the above-mentioned download messaging format, and transfers the data to the mobile device via the large capacity data transfer system 30. (M
S) Send to 11 ().

Next, the operation when the user identification number (UID) is required for downloading the content will be described. FIG. 9 is a diagram for explaining downloading of contents that require a user identification number.

Currently, businesses generally use their mobile phone number (MSN) to identify themselves. There is a need from the information provider (IP) side to create a customer database by specifying each user and manage the service usage history of the user independently, but the mobile phone of the user that is a part of personal information. It is a security problem to directly issue the number to the information provider (IP) outside the network of the business operator. Therefore, the mobile phone number (MSN) is converted into a UID based on a specific rule, and the information provider (IP) uses U instead of the mobile phone number.
The ID is used to create a customer database so that the service usage history can be managed.

That is, as shown in FIG.
A request for downloading the content that requires D is sent from the mobile device (MS) 11 to the mass data transfer system 3
When transmitting () to the information providing system 70 via 0, the information providing system 70 displays the data of the UID transmission agreement confirmation screen for transmitting the UID when accessing all the contents that require the UID. It returns to the mobile station (MS) 11 via the mass data transfer system 30 (). When the user agrees to send the UID and sends the agreed data to the information providing system 70 via the mass data transfer system 30 (), the information providing system 70 agrees the agreed mobile phone number (MSN) with the UID. Based on a specific rule, the mobile phone number included in the user request messaging format AMTS is converted into a UID (1 UID for one mobile phone number) (), and the UID and request are provided to the information provider ( IP) 22 (). The information provider (IP) 22 sends the requested content to the information providing system 70 and the large capacity data transfer system 3 as described above.
Download to mobile unit (MS) 11 of the user via 0 (). Once the UID transmission is agreed, the transmission agreement is not confirmed from the next request. The information provider (IP) 22 can use the UID to create a customer database and manage the service usage history.

The large-capacity data transfer system 30 is a system that only transfers data, and cannot send data from the direct access system (DAS) 31 to the mobile device (MS) 11 side. Therefore, the conventional short message service center ( Using the SMSC) 14 as a bearer, for example, a push service such as automatically delivering a weather forecast at 6 am every day is realized by the two methods described below.

FIG. 10 is a diagram for explaining an operation example of the push service.

This push service sends a notification to the user and causes the mobile station (MS) 11 to retrieve the data on the side of the mass data transfer system 30. That is, as shown in FIG. 10, the information provider (IP) side that creates the content transmits an automatic distribution request message to the user via the short message service center (SMSC) 14 at a preset time. This “message” includes a link for going to the content in the mass data transfer system 30. When the user selects this link, the request for the content is sent to the mass data transfer system 30 side, This content is being downloaded.

11 to 13 are diagrams for explaining other push services, FIG. 11 is a diagram showing a message format of user data, FIG. 12 is a diagram showing a table set in the control timer of the message format, and FIG. FIG. 8 is a diagram illustrating another operation example of the push service.

This push service is to automatically issue a request from the mobile device (MS) 11 side without the user's operation and distribute the content data by the large capacity data transfer system 30. This is implemented in a short messaging format that is prepended to the user data. That is, as shown in FIG. 11, in the transaction-type short messaging format, a message header, which is a message control protocol (AMCP) for providing information, is added to the head of data such as mobile device markup language (MML). And the bearer identifier for which the bearer service is set from the beginning and the AM
The protocol version in which the CP version is set, the AMCP identifier in which an identifier for identifying the type of AMCP operation in AMCP messaging, the type of messaging, etc. is set, the spare and the automatic push service are provided in the mass data transfer system 30. In order to achieve the above, a control timer (Redirect Control Timer) added to raise an automatic request to the downlink messaging format and a key that is a preliminary information element for concealing and authenticating data exchanged between terminals And a session number assigned to identify a messaging session, and a sequence number that is a sequence number in the session.

When distributing the content of this push service, the information providing system 70 determines that the AMCP message header is used when the R attribute is included in the anchor tag of the data such as the markup language (MML) for the mobile device of the content. As shown in FIG. 12, the control timer is set to 10 seconds later, 20 seconds later, ..., 60 seconds later, immediately performed, etc. Then, as shown in FIG.
After setting the P message header control timer, trigger the mobile station (MS) 11 via the short message service.
Send to (). The mobile station (MS) 11 judges the control timer of the AMCP message header and automatically sends a download request to the information providing system 70 via the large capacity data transfer system 30 (). Upon receiving the download request, the information providing system 70 goes to the information providing source (IP) 22 for the requested content, and transfers the obtained content to the mobile station (MS) 11 via the large capacity data transfer system 30. to download(). That is, in this push service, the mobile device (MS) 1
The timing at which the large-capacity data transfer system 30 makes a request for delivery is different for each item. A
By referring to the control timer of the MCP header and distributing the distribution request timing within a range of up to 60 seconds, it is possible to avoid a situation in which downloads are concentrated and crowded at the same time.

In the above push service, the mobile station (MS) 11 judges the control timer of the AMCP message header, and when the timer expires, it automatically sends a request to the mass data transfer system 30. For users who have downloaded content freely and do not want to be charged, the mobile device (MS) 11 is set to be automatically or manually and the user can automatically download the push-delivered content. A processing unit 58 is provided. When the setting is set to “automatic”, the automatic acquisition setting processing unit 58 confirms that the R attribute is included in the anchor tag of the MML data included in the automatic delivery request message, and the control timer expires. When the process is performed to raise the request to the large-capacity data transfer system 30 and the setting is set to "manual", even if the R tag is included in the anchor tag of the MML data included in the automatic delivery request message, the control timer Ignore and do not make a request. Only when the user selects the link of the content included in the automatic delivery request message, the process of raising the request to the mass data transfer system 30 is performed.

Further, the message communication system 10 has a suspend function and a line hold function in order to change the line connection mode according to the content and use the wireless equipment efficiently, and the session in the mobile unit (MS) 11 is performed. The control unit 53 performs processing for realizing these. For example, if a user downloads quiz content, the user will need time to think of an answer. However, the line is still connected during that time, and it is an inefficient use method of the wireless equipment that another user cannot use the channel. In order to solve this problem, the suspend function is realized. First, the information provider (IP) 22 who wants to use the suspend function uses, for example, <! ENDCOM = SUSPEND> in HTML at the beginning of the content provided by himself.
Write. When the content is downloaded from the information providing source (IP) 22 together with this description, the information providing system 70 sets the DALP identifier in the DALP to suspend and the mobile device (MS) via the mass data transfer system 30 together with the content. Send to 11 side. The session control unit 53 of the mobile device (MS) 11 determines that the DALP identifier is suspended, disconnects the line, and performs processing for holding a quiz screen, which is an application. When the user inputs an answer and makes a call, the session control unit 53 performs a process for reconnecting to the network side. In order not to lose track of the existing session at the time of reconnection, a unique session number (up to the 24th power of 2) is set on the mobile device (MS) 11 and the network side, and management is performed within the DALP. For example, when the network has 123 and the mobile station (MS) 11 has set the session number of 456, the respective information is D
Recorded in the session number in the ALP, the
S) 11 and the network side judge these session numbers and manage the session after disconnection and restoration of the line.

In the case of the above-mentioned suspend function, if the line is disconnected once and congestion occurs, the service may be terminated in the middle such that the quiz is answered but no response is received from the network side. Therefore, it is possible to provide the service while keeping the line. That is, to hold the line, the information provider (I
P) 22 is, for example, <!
Describe as ENDCOM = TRANSACTION>. When the content is downloaded from the information provider (IP) 22 along with this description, the information providing system 70 determines that the DAL in the DAL
The P identifier is set in the transaction, and the mobile device (M
S) Send to 11 side. The session control unit 53 of the mobile device (MS) 11 determines that the DALP identifier is a transaction and waits for a user action while holding the line.

Further, in the message communication system 10, the markup language for mobile devices (this is called S-MML) used in the conventional short message service having a maximum bearer capacity of 384 bytes is compatible with various functions. The markup language for mobile devices (which is called M-MML) that can be used in a large-capacity data transfer service in which the bearer has a capacity of 6 kilobytes has been expanded. Below, the example of a main additional function is demonstrated.

FIG. 14 is a diagram for explaining an example of downloading a BGM file.

The first extension is background music (BGM), whose tag is <BGM SRC = "
url ">. Here, url represents the URL of the music source on the network. The file uses a predetermined sound code extended to support chords. As shown in Fig. 14, <BGM When SRC = "url"> is selected, the BGM file on the Internet 21 is downloaded to the mobile station (MS) 11 via the large capacity data transfer system 30 and the information providing system 70. When this tag is included in the content downloaded to the MS 11), this binary file is transferred to the melody data analysis unit 54 and the BGM is repeatedly reproduced. Been BG
If you press the [Register] button while playing M, you can register this BGM as a ringtone, wakeup sound, shutdown sound, key press confirmation sound, etc., and if you change from this screen to another screen, stop BGM. .

FIGS. 15 and 16 are diagrams for explaining an example of displaying an animation image on a mobile device, FIG. 15 is a diagram for explaining image scrolling, and FIG. 16 is a diagram for explaining image switching.

The next extended function is an animation image in which an image to be displayed is switched to a moving image, and is realized by image scrolling and image switching in the display control unit 48 of the mobile station (MS) 11. In image scrolling, the display control unit 48 controls different images to be displayed at different locations on the display unit 52 so that the images appear to be moving. The MML tags in this case are as follows, for example. <IM MTN = "Image file for animation 1" URL of MTN = "Image file for animation 2""MTN=" Image file for animation 3 "= DR = 1 / r FSH = 1/2> Character string of link here , DR = l or r indicates the scroll direction, 1 is right to left, r is left to right, the image is displayed as a whole, the character string is displayed from one side, and the movement is repeated across. "Speed" is the interval to display one at a time, about 720msec = 1,
About 1440msec = 2. ALI = t displays the specified character above the image, and ALI = c / b displays the specified character below the image. When the mobile station (MS) 11 receives the file in the above format or reads the file already received and stored in the message memory 51,
The display control unit 48 displays the image on the display unit 52 as specified by the MML tag.

The MML tag is a flip-flop image <IM MTN = "anime1.png" MTN = "anime2.png"
DR = 1 FSH = 1 ALI = t> PNG In the animation example, as shown in FIG. 15, for example, an image of a person running scrolls from right to left in about 720 msec, and the designated character is displayed on the image. To be done. This image is recorded and read by a dedicated working memory. Also MM
L tag is a flip image <IM MTN = "anime1.png" MTN = "anime2.png" F
In the example of SH = 1 ALI = t> PNG animation, as shown in FIG. 16, for example, the image of a person running changes every 720 msec, and the designated character is displayed on the image.

A "moving pictogram" is realized based on the above image switching. Add "moving pictograms" consisting of up to 6 frames to the code table. The mobile device (MS) 11 is provided with a character fixed storage unit 64 for storing the data of the "moving pictogram".

It is transmitted to the mobile station (MS) 11 of the call destination via the via. At that time, the mail gateway system (MGS) 19 recognizes that delivery confirmation is set for this long mail. When the destination mobile station (MS) 11 receives the "incoming call notification", it sends a short message as a reply indicating that it has received by the short message transfer protocol (SMTP) used for the bearer of the existing short message service. It returns to the mail gateway system (MGS) 19 via the service center (SMSC) 14. Upon receiving this reply, the mail gateway system (MGS) 19 transmits a delivery confirmation status to the transmission source mobile device (MS) 11.
That is, as shown in FIG. 23, mobile unit A (MS-A)
When a long mail for delivery confirmation is sent from 11 (), it is stored in the post office 20 via the mass data transfer system 30 and the mail gateway system (MGS) 19. Next, the mail gateway system (MGS) 19 sends 38 messages from the beginning of this long mail.
An “incoming call notification” including 4-byte text data is transmitted to mobile station B (MS-B) 11 via short message service center (SMSC) 14 (). Here, the mail gateway system (MGS) 19 is
The TP recognizes that delivery confirmation is required. Mobile device B
When the "MS-B" 11 reaches the "incoming call notification", the mobile unit B (MS-B) 11 sets the fact that the "MS-B" 11 has received the "incoming call notification" and sends it via the short message service center (SMSC) 14. To send to the mail gateway system (MGS) 19 (). Next, the mail gateway system (MGS) 19 transmits that the delivery of the long mail has been completed to the mobile device A (MS-A) 11 by SMTP via the short message service center (SMSC) 14 ().

Since the introduction of the large-capacity data transfer system 30 has made it possible to transfer a maximum of 6 kilobytes of data for both the mail service and the information transfer service, the image data in the memory of the mobile station (MS) 11 at the time of creating a long mail, It is also possible to copy / paste sound data and send it together with text data.
