Description of the Related Art Conventionally, with the development of mobile communication such as a radio telephone system, not only voice communication but also a terminal user such as a mobile device is composed of characters, numerals or data via a mobile network. Two-way communication using simple messages can be performed. The present applicant has proposed, for example, in Japanese Patent Application No. 9-74669 or the like, a technique relating to a radio telephone device and a radio telephone system capable of exchanging a simple message. On the other hand, with the rapid development of the Internet in recent years, individuals can access a WWW (World Wide Web) server from a terminal such as a personal computer, and can receive various information services from an information provider or a service provider. Internet users are increasing rapidly.

[0003]

The marketability of an information providing service has been expanding in message communication using a wireless telephone system or the like. For example, a weather forecast, a news headline, sports news, or There is a demand for providing information services such as various reservation services. In the provision of an information service by such a radio telephone system or the like, for example, a pull-type messaging in which a user of a mobile device reads out an information service by himself / herself, a push-type messaging in which an information service provider automatically distributes update information. However, depending on the type of information service, the user obtains the desired information service between the user of the mobile device and the information service provider side by repeatedly requesting and distributing the request multiple times. There is a need for a type of messaging that ends sometimes (hereinafter, transactional messaging). In order to configure a wireless telephone system that can provide information services by such transactional messaging, it is necessary to not only transfer messages as in conventional wireless telephone systems, but also to manage sessions such as establishing and releasing communication paths. It needs to be done properly. When receiving information services from information service providers on other communication networks, such as the Internet and wide area networks, a type of document notation standard is subject to restrictions on the amount of information that can be handled on the mobile device side. It is necessary to solve the problems in connecting to the WWW server of the information service provider described in Hyper Text Markup Language (HTML).

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and enables a wide range of information service providers to be easily accessed based on a user request from a mobile station, and to provide necessary information services interactively. An object of the present invention is to realize an information providing service system using a digital radio telephone.

[0005]

In order to achieve the above object, an information providing service system using a digital radio telephone according to the present invention comprises a mobile station having a message display function and an information providing center for providing an information service. A user request for obtaining a required information service from the mobile device, and a reply of the information service corresponding to the information providing center which has received the user request, are finally formed. It has a transaction-type messaging mode in which the user makes a round trip a plurality of times until a required information service is obtained.
In the management of the TTM, a session and a sequence number are assigned to each transmitted message, and the management within the same session and the management of the transmission order are performed, and a user request and an information service response are finally required. By going back and forth a plurality of times before obtaining the information service, the required information service can be easily received interactively.

The bearer service used by the application of the mobile communication network is a short message service provided by a short message center provided between the mobile device and the information providing center. The fields in the user-to-user data block transferred in the field include a message header constituting a message control protocol of an information providing service, and data described in a markup language for a mobile station constituting a user data or a message update for a mobile station. The setting of link protocol data enables efficient transfer of messages by performing session management such as establishment and release of a communication channel, and uses a tag with a shortened HTML, and has a small capacity. It is preferable because a system suitable for data communication can be constructed. There.

[0007] The mobile device markup language is provided in a downlink from the information providing center to the mobile device,
A tag having a shortened tag used in the hypertext markup language is used, and has a format having a structure in which a portion sandwiched between tags including a version indication is a document, and the message uplink protocol for the mobile device is In the uplink from the mobile device to the information providing center, the version indication, the link destination information including the selected keyword or URI, and the user input information, and considering the compatibility with the hypertext transfer protocol Having a format
HTML from a mobile device to a WWW server such as the Internet
This is preferable because data can be easily accessed.

[0008] The information providing center transmits an information service message to the mobile station from a content database of information contents obtained from the information service provider, or transmits the information service provider connected to another communication network. A function for connecting a device and the mobile device between terminals and transmitting an information service message to the mobile device; receiving a user request from the mobile device and receiving a user request from the mobile device; It is preferable that the location of the information providing service can be easily transferred to the location of the information providing service by specifying the location of the user, transferring the user request according to the route information, connecting to the Internet WWW, and enabling access to the home page.

The information providing center converts the data written in the mobile station message uplink protocol into data of a hypertext transfer protocol and transmits the data to another communication network, and conversely transmits the data from another communication network. Converting the data in the hypertext markup language into data in the markup language for a mobile device and transmitting the converted data to the mobile device side allows the mobile device to easily access HTML data of a WWW server such as the Internet. It is preferable in that it can be performed.

[0010] The mobile station has a received message management unit that sorts and arranges the received messages according to a message management class designated by the network side and a title or a link keyword sandwiched between message title tags, and stores the messages in a message memory. However, this is preferable in that the received message can be easily viewed on the display unit.

The received message management unit may sequentially update and store the new main menu in the message memory each time a new main menu provided from the information providing center is received in response to a user request. It is preferable in that it can cope with traffic and can reduce traffic.

The received message management unit overwrites and updates the keyword of the new submenu provided from the information providing center by a user request when the keyword is already stored in the message memory with the same title. If not stored in the title, delete the oldest submenu in chronological order and store the received new submenu in the message memory, so that even if the menu changes dynamically in the future, traffic will also be reduced This is preferable because it can be reduced.

[0013] The main menu and / or sub-menu stored in the mobile device can be browsed without communication within the mobile device, and an information service can be accessed from the main menu or sub-menu. When the main menu and / or sub-menu is newly updated on the center side, it is possible to update the stored main menu and / or sub-menu by downloading, even if the menu dynamically changes in the future. It is preferable in that it can respond and reduce traffic.

When the received message management unit receives a message, if the same title exists in the already stored message sequence in the message memory, the received message management unit deletes the oldest message in the message sequence in chronological order and deletes the new message sequence. A message is added to the message sequence.If the same title does not exist and there is room in the message sequence, it is stored in the message memory as a new title.If there is no room in the message sequence for each title in the message memory, the oldest in time series It is preferable to delete the message string of the title and store the received message of the title in the message memory in that the message which has no value over time can be automatically deleted.

The received message management section stores the received message as a designated message when the memory area of the message memory is empty, and when the memory area is not empty, the mobile unit prompts the user to delete the message and prompts the user to delete the message. It is preferable to store the received message in the message memory when the memory area is vacated by the operation, since the received message can be efficiently stored in the limited memory of the mobile device.

[0016] The received message management unit is configured to uniformly and temporarily store a message received during a transaction session as a designated message in a message memory until it finally reaches necessary information. This is preferable in that the data received at the first time is not inadvertently stored in the memory.

It is preferable that the mobile device has a voice incoming call setting section for setting an operation when a voice call is received in the transaction type messaging mode, in that the setting can be made when a voice call is received.

The voice incoming call setting unit, when the mobile device receives the voice incoming call, unconditionally transitions to a voice incoming state according to a previously set setting, cancels the transactional messaging mode after the call, Alternatively, it is preferable in that the voice incoming call can be rejected unconditionally by sending the call rejection.

The voice incoming call setting unit displays a calling number on a display unit of the mobile device when the mobile device receives a voice incoming call, shifts to a voice incoming state at the discretion of the user, and sets a transaction type after the call. It is preferable that the voice call is rejected by canceling the mode of the messaging or by transferring the voice call to the answering machine service in that the operation according to the user's request can be performed.

The bearer service used by the application of the mobile communication network can be used for switching to a plurality of bearer services such as packet and circuit switching in addition to the short message service. This is preferable because it can be switched to a system.

FIG. 4 is a diagram for explaining in detail the structure of the inter-user information data block portion of the embodiment of the present invention. FIG. 5 shows a transaction format of user data messaging format of the embodiment of the present invention.
5A shows an uplink format, and FIG. 5B shows a downlink format.

As shown in FIG. 4, RC issued by the Association of Radio Industries and Businesses
Based on the service 1 "Implicit Acknowledgment" in the R27 standard, the user control (UUI) included in the call control is used, the UUI comprising an element identifier consisting of one octet each, a user data length, and a protocol identifier. And user data of a maximum of 128 octets, and the user data is composed of AMCP and Mobile Station Markup Language (MML) or Mobile Station Message Uplink Protocol (AMUP). AMCP
Is a part for performing session management and the like in transactional messaging that constitutes a feature of the present invention, and details thereof will be specifically described.

As shown in FIG. 5, the messaging format in transactional messaging is:
A message header is added to the head of MML or AMUP data. In the case of an uplink from the mobile station (MS) 11 to the information providing center (AMP) 16, the message header includes a bearer identifier, a protocol version, and an AM from the beginning, as shown in FIG.
It consists of a CP identifier, a spare, a key, a session number, and a sequence number. In the case of a downlink, as shown in FIG. 4B, the bearer identifier, the protocol version, and the AMCP identifier from the beginning. And AOIC (Advice of InformationCharge) which is a charge notification information element
, A spare, a key, a session number, and a sequence number. Here, the bearer identifier is used by the application, for example, the short message service (S
MS) or another part where a bearer service is set. In the present embodiment, a short message service is set. Therefore, the mobile device (MS) of the present embodiment
No. 11 ignores this information when anything other than “SMS” is set. The protocol version is for setting the version of AMCP and responding to a version upgrade due to a function extension of the protocol in the future. As the AMCP identifier, an identifier for identifying an AMCP operation type, a messaging type, and the like in AMCP messaging is set. AOIC is a charge notification information element of the content to be distributed, and the charge frequency of the content is set. Reserve is a reservation information element for future expansion. The key is an optional information element for concealing and authenticating data exchanged between terminals. The session number is used to identify the messaging session by the mobile station (MS) 11 or the information service center (AM).
P) This number is assigned from 16. The sequence number is a sequence number in a transaction type messaging (TTM) session, and the TTM sequence control is performed.

Next, an example of session management in TTM will be described. In the TTM signal sequence, the message header (AMCP) is used for both the uplink and the downlink.
Header) and use two parameters, session number and sequence number, to perform TTM link establishment, transaction session number and sequence number management, TTM link release and TTM link forced release, etc. according to the following procedure. Will be

In establishing a TTM link, first, a mobile station (M
A request for a session is made by a TTM request message from S) 11 or the information providing center (AMP) 16. Then, in the user data of the TTM request message, path information such as a keyword, a sub-keyword or a parameter is set. Upon receiving a positive response to the TTM request, the mobile station (MS) 11 or the information providing center (AMP) 16 establishes a TTM link, and the mobile station (MS) -information providing center (A).
MP) are established in effect.

Next, in managing the transaction session number and sequence number, first, the mobile station (MS) 1
1 and the information providing center (AMP) 16 set a session number generated by the mobile station and the information providing center in each transaction during the TTM session. In addition, the sequence number is sequentially incremented and set for each transaction for the uplink and the downlink separately,
Continue the session. When the mobile station (MS) 11 receives an abnormal sequence number, it receives it inside the mobile station (MS) 11 but ignores it. Then, during the transaction, it is possible to use linked messaging only for the downlink. In this case, the message header is
It is added only to the first message of the concatenated message, and not to subsequent concatenated messages. Except for the case of a concatenated message, messages between transactions basically exchange messages alternately between the mobile device and the information providing center.

In the release of the TTM link, first, the mobile station (M
S) 11 or the information provision center (AMP) 16
The session can be interrupted at any time by sending a "TTM release" during the TM session.

In the TTM link forcible release, for example, when a response message from a partner does not arrive for a predetermined time in the TTM session, the TTM session can be forcibly terminated. In this case, the transmission is performed by unilaterally transmitting “TTM link forced release”.

Next, a mobile device markup language (MM)
L) will be described in detail. MML is a simplified language of HTML, and as described above, the mobile station (MS) 11
~ Specially developed as used in user data of the application layer between the information providing center (AMP) 16. Since MML basically uses the tags used in HTML in a shortened form, the HTML
L is a subset of L. In the short message service, since the data transfer capacity is low, the MML is applied to the application layer. However, when a bearer capable of obtaining the data transfer capacity is set, the extended MML coexists.

FIG. 6 is a diagram showing an example of an MML downlink format corresponding to HTML according to the embodiment of the present invention.

The rules for MML processing are as follows. (1) <T> is treated as the “subject” of information, and mobile device 1
1 is used to search for a message stored in an internal memory. (2) The mobile station 11 stores <T> when storing the message.
They are sorted and stored in order of the date and time of acquisition. (3) In transactional messaging,
The message stored in the memory by the mobile device 11 depends on the memory management class (described in detail later) specified by the parameter setting of the memory management class identifier. (4) MML is used not only for transactional messaging but also for push messaging. (5) The mobile device 11 does not determine the case of the characters used in the tag, and performs the same process whether the tag received by the mobile device 11 is uppercase or lowercase. (6) The mobile device 11 supports at least special characters such as ampersand (&a;), greater than inequality (&g;), less than inequality (&l;), double quotes (&q;) and space (& n). And also captures other escape codes. (7) When receiving the unsupported tag, the mobile device 11 ignores the tag.

Next, a part of an example of the MML tag used in the AMS will be specifically described.

MML uses H in order to reduce the amount of data.
The part where efficiency is improved by shortening TML is shortened, and the structure such as <HTML>, <HEAD>, <BODY> is simplified, and the part between <1> to </ 1> described later Is MM
Indicates that the information is for an L document. (1) The <1> to </ 1> tags indicate MML version 1, and it is considered that characters such as <2> are designated as the next version of the mobile device 11. (2) <T> to </ T> are used as “subjects” of the stored received message information. (3) The <BR> tag inserts the tag at the position where the line break is desired when the sentence is forced to be broken like the HTML. (4) The <P> tag is inserted at a position where a paragraph is to be changed when it is desired to divide a paragraph in the same way as HTML. In a general WWW browser, when the same tag is inserted, an empty line is inserted, but in MML, an empty line is not inserted. (5) When it is desired to underline a character string included in a message, a character string specified by <U> to </ U> tags is sandwiched in the same manner as in HTML. (6) To blink a specific character string included in the message, the character string specified by the <BL> to </ BL> tags is sandwiched. (7) Automatic scrolling of a specific character string (horizontal direction)
If you want to do so, sandwich the character string specified by <MQ> ~ </ MQ> tags. When all characters have been scrolled, scrolling starts again from the first character. (8) Character color is changed by sandwiching a specific character string between <FN> to </ FN> tags. Specify the color of the characters in the format "#rgb". For each of "r", "g", and "b", the intensity is specified in red, green, and blue by a hexadecimal number from 0 to f. The mobile device 11 that does not support the <FN> to </ FN> tags ignores only the tags and displays the content between the tags in monochrome or the like. (9) By sandwiching a specific character string between <C> to </ C> tags, the inserted character string is centered. (10) By inserting a specific character string between <DL> to </ D> tags, the inserted character string is left-aligned. By inserting a specific character string between <D R> ~ </ D> tags,
Right justify the sandwiched string. (11) Similar to HTML, a specific character string is
By sandwiching between <UL> ~ </ UL> tags, a specific character string can be listed. The contents of the bulleted list can be hierarchized, and items are described after <L> of <UL> ~ <L> ~ </ UL> tags. When displaying on the display unit 42, the mobile device 11 inserts a middle point “• (half-width)” before an itemized list.

Next, the format of the mobile station uplink protocol (AMUP) transmitted from the mobile station (MS) 11 will be described. (1) The version display is, for example, M / 1. The version display here is MML, AMUP and AMCP
Indicates the version and has a fixed length of 3 bytes. The transmission of the version display is indispensable. (2) The format of the link information indicates the selected keyword or URI link destination information. The keyword and URI value to be sent can be set by link tag,
Or directly entered by the user. In the user's input, only the keyword or URI address is entered, and delimiters such as delimiters and “#” at the time of keyword input are not input. The mobile station 11 selects the selected keyword or U
Add "?" After RI. For example, # keyword? For keyword, and http: // ww for URL
w.address? (3) The format of the form information indicates the transmission format of the input form selected by the user,
Shown as Name = Value. The mobile device 11 adds “& +” as a delimiter of each input field. here
The Name field sets the value of the Name included in the input tag defined in the downlink MML, and the Value field sets the value entered or selected by the user.

Next, a specific example of the MML and a display example on the display unit of the mobile device will be described.

First, the MML example relates to sports news. 1. MML example of user request M / 1 # Sports news? 1-A. Example of downlink MML <1><T> J-Phone Sports News </ T><H><UL><L><AH = "# bball"> Baseball </A><L><AH = "# fball "> Soccer </A><L><AH="# sumo "> Sumo </A><L><AH="# golf "> Golf </A></UL></1> 1 B. Uplink AMUP example M / 1 #fball? In the above example, the mobile station 11
L and AMUP uplink version display (version 1), and sports news, which is a keyword of link information, and a delimiter added thereto are transmitted. On the other hand, in the downlink MML example, the version (version 1) and the subject of the received message, J-Ph
One sports news and the horizontal line below it, the link destination keyword and the character string of the linked link part are transmitted to the mobile device 11 as bball and baseball, fball and soccer, sumo and sumo wrestling, golf and golf, respectively. .
When the mobile device 11 selects soccer, the version is displayed from the mobile device 11 and fball which is a keyword of the link information is displayed.
And the delimiter attached to it.

FIG. 7 is a diagram showing a display on the mobile device of the MML example of the embodiment of the present invention, in which J-Phone sports news, which is the subject of the received message, and a horizontal line are displayed below, and a horizontal line is displayed below the horizontal line. Baseball, soccer, sumo wrestling and golf, which are underlined in bullets, are each displayed with a leading middle point. In this display, options can be selected by moving the cursor, for example, soccer.

Next, the operation of the received message manager 37 of the mobile station (MS) 11 will be described in detail. Mobile device (MS)
11 is managed differently depending on the memory management class identifier of the message and the title (<T> to </ T>) which is the subject of the message. Although the description of the details of the parameter setting of the B protocol relating to the data transfer of the information providing service of the present embodiment is omitted, the lower 3 octets of the memory management class identifier (4 octets) are used, and the mobile station (MS) transmits from the network side. 11 is designated for managing each message. The message management class specified by the parameter setting of the memory management class identifier is defined as five classes. For example, each of the main menu (message management class A), the submenu (message management class B), and the FIFO type message (message management class) C), a storage type message (message management class D) and a work memory (message management class E).

FIG. 8 is a diagram for explaining the transition state of the message management class according to the embodiment of the present invention.

FIG. 5 shows an example of use of an application for performing a route search of a route, for example. When the route search is selected in the main menu of the message management class A, a transition is made to a submenu of the message management class B. Next, when selecting the route selection, the message management class E
When a search is selected by inputting a departure station and a destination station, a transition is made to a storage type message of the message management class D, and the route, time and fee of the search result are indicated.

Next, an example of processing for each message management class will be specifically described. FIG. 9 is a view for explaining a processing example of the message management class A of the embodiment of the present invention.

In this message management class A (main menu), a request from the mobile station (MS) 11
The main menu distributed from the information providing center (AMP) 16 is stored in the message memory 41. And
The management class A message is sequentially overwritten and updated each time a new main menu is received.
