Description

  The present invention relates to an information distribution system, an information distribution method, and an information distribution program for providing information with variation in a timely manner.

Today, various types of information are provided through the Internet and various transactions are being realized on the Internet. In particular, when there is a price movement for each brand as in stock trading, it is necessary to grasp the latest price movement and conduct timely trading. However, in the case of stock trading, there are many issues to be traded, and it is not possible to monitor all stock price information provided by securities companies. Further, if the stock price information is searched for the desired brand and the information is acquired, the timing may be lost during the operation. For this reason, a client / server type information distribution system in which market information such as securities and stock prices transmitted from a stock exchange is received by a server and distributed in response to requests from a plurality of clients has been studied (for example, patents). See reference 1.) In the technique described in this document, the received data processing means of the server detects the presence or absence of an update due to price movement based on the received market information, updates the stock price information in the brand information storage table, and further sets an update flag. Then, the request reception processing means distributes the brand attribute information, the stock price information, and the update flag for the distribution request brand that has received the distribution request from the client. Thereafter, the distribution control processing means periodically determines the occurrence of the update for the brand requested by the client, and distributes the stock price information and the update flag to the client only for the brand for which the update is detected. As a result, a certain amount of real-time performance can be maintained while reducing traffic between the server and the client.
JP 2000-242697 A (first page)

  When providing information by the above-described client / server method, pull type information distribution technology and push type information distribution technology can be used. In the pull-type information distribution technology, a request is transmitted from the client to the server, and a response is returned from the server in response thereto. With this technology, information can be acquired only upon request. FIG. 7 shows a method for realizing the real-time property in a pseudo manner using this technique. Here, when the client terminal periodically sends a request, the server provides pull data to the client. However, in order to improve the real-time property, it is necessary to increase the request frequency. In this case, while the load due to traffic increases, the communication processing is performed even when there is no change in information, so the load on the server increases. Further, when the request frequency is lowered, information generated between requests cannot be acquired.

  On the other hand, in the push type information distribution technology, even when the client side does not request, the server side sends information unilaterally. For this reason, for example, information can be grasped in real time.

By the way, in the pull type information distribution technology, the time between responses to the request from the client to the server is monitored, and if it does not end within a certain time, it is monitored in the client application so that a communication error occurs. Yes. On the other hand, in communication with a mobile object such as a mobile phone terminal, a communication failure often occurs temporarily on the mobile phone network. In this case, if the session is disconnected for each failure, reconnection becomes complicated. For this reason, a function for continuing a TCP / IP (Transmission Control Protocol / Internet Protocol) session without causing an error as much as possible is required. However, in the push-type information distribution technology, the client side is waiting for push data from the server, and therefore cannot grasp the communication status. Therefore, it is difficult to determine whether there is actually no push data or whether the session is disconnected.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an information distribution system, an information distribution method, and an information distribution program for accurately providing variable information to a mobile terminal or the like.

  ADVANTAGE OF THE INVENTION According to this invention, the information with a fluctuation | variation can be provided exactly with respect to a portable terminal etc.

  Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. The present embodiment will be described as an information distribution system, an information distribution method, and an information distribution program for providing sequentially changing stock price information. In the present embodiment, an information distribution system is assumed that implements a stock price information distribution service that provides information on stock issues desired by a user to a user's mobile phone terminal.

  As shown in FIG. 1, a user's mobile phone terminal 10 is connected to a stock price information distribution server 20 and a securities company server 30 via a base station 60 of the mobile phone network and the Internet. In the present embodiment, the stock price information distribution server 20 functions as an information distribution system.

The mobile phone terminal 10 is a mobile terminal used when a user accesses the stock price information distribution server 20 or the securities company server 30. The mobile phone terminal 10 has a function of transmitting / receiving e-mail and a data communication function for communicating with each server in addition to a normal telephone call function.

  The mobile phone terminal 10 and the stock price information distribution server 20 are always connected by TCP / IP via a network constituted by a mobile phone network (base station 60) and the Internet. Thereby, the mobile phone terminal 10 receives and displays real-time automatic update information such as stock prices. Here, TCP / IP connection using a mobile phone terminal as a client is different from communication using TCP / IP connection using a PC as a client. In other words, even in the event of a momentary communication interruption due to radio interference, the TCP / IP connection with the Internet is maintained in the mobile phone network so that the TCP / IP session can be continued without disconnection, and communication in the physical layer with the terminal It is possible to continue regardless of the state. That is, the physical error state is not notified to the TCP layer.

  The mobile phone terminal 10 includes a display unit, a selector button, and a mode switching button in addition to the dial number button. In addition to the normal telephone mode, the mobile phone terminal 10 has a mail mode for sending and receiving e-mail, a browser mode for displaying web pages, and a program execution mode for executing various programs. . When switching from each mode (for example, telephone mode) to another mode (for example, program execution mode), a mode switching button is used.

  In addition to the web page received by the mobile phone terminal 10, various screens based on programs stored in the mobile phone terminal 10 are output to the display unit. The selector button has a pointer movement function and a click function. The pointer can be moved by giving a direction instruction using the selector button, and the item indicated by the pointer can be selected by pressing the selector button. Various data can be input using a dial number button or the like.

  Furthermore, the mobile phone terminal 10 includes a control unit and a program storage unit including a CPU, a RAM, a ROM, and the like in addition to the communication means. In the present embodiment, a stock price information display program described later is stored in the program storage unit. The control unit of the mobile phone terminal 10 performs a processing procedure described later regarding the stock price information display process (step of receiving newly arrived information using a push protocol, step of receiving a signal for confirming a connection state, and the interval being a reference value. If it exceeds, execute an alarm output step). As a result, the control unit of the mobile phone terminal 10 functions as a new arrival information reception unit using a push protocol, a connection state confirmation signal reception unit, an alarm output unit when the interval exceeds the reference value, or the like.

The RAM of the mobile phone terminal 10 functions as a memory for recording time data, and stores time data acquired from the stock price information distribution server 20 as will be described later.
The stock price information distribution server 20 is a computer server that distributes stock price information to the user's mobile phone terminal 10. The stock price information distribution server 20 includes a control unit 21. The control unit 21 includes a control unit (CPU), a storage unit (RAM, ROM, etc.), a communication unit, etc. (not shown). Then, the stock price information distribution server 20 executes a processing procedure (such as a mobile terminal identification stage, a new arrival information transmission stage, a connection state confirmation signal transmission stage). By executing the information distribution program for this purpose, the control unit 21 functions as a portable terminal specifying unit, a new arrival information transmission unit, a connection state confirmation signal transmission unit, and the like.

Here, when the mobile terminal specifying means acquires new arrival information, it specifies a new arrival information item included in the new arrival information, specifies an item registration list including the new arrival information item as a distribution desired item, and corresponds to this item registration list. Identify the mobile device you want to The new arrival information transmission means transmits the new arrival information to the mobile terminal using the push protocol while maintaining the session even if there is a physical layer communication abnormality. The connection state confirmation signal transmitting means performs a connection confirmation process for transmitting a signal for confirming the connection state with the portable terminal to the portable terminal at a predetermined timing.

Further, the stock price information distribution server 20 includes a stock price information storage section and a brand registration list storage section 22 as distribution list storage means.
Then, the stock price information distribution server 20 receives the stock price information from the exchange system 40 in real time and stores it in the stock price information storage unit.
The stock price information is configured to include an item to be distributed (here, a brand code) for specifying a brand to be targeted.

  In the brand registration list storage unit 22, a brand registration list is registered for each mobile phone terminal 10 as an item registration list. In this brand registration list, data for specifying a brand for which information distribution is requested from the mobile phone terminal 10 is recorded. Here, in the brand registration list, information related to the brand code is recorded in association with the terminal identifier for specifying the mobile phone terminal 10 that distributes the information. This brand registration list is recorded when a registration request is received from the mobile phone terminal 10. Then, it is deleted when the session with the mobile phone terminal 10 is disconnected.

  The securities company server 30 is a computer system of a securities company that manages customer securities. The user of the stock price information distribution service of this embodiment is a customer of a securities company, and user registration is performed in order to use this service. Furthermore, the securities company server 30 includes a user brand list information storage unit 32. A user of this service accesses the securities company server 30 and registers a user brand list. In the user brand list information storage unit 32, a user brand list is registered for each user. These registration processes will be described later.

  Next, the processing procedure of the stock price information distribution service will be described using the above system. In this embodiment, a user registration process, a stock price information display program activation process (FIG. 2), a stock price information distribution process (FIG. 3), and a communication state monitoring process (FIG. 4) will be described in this order.

(User registration process)
First, when using this stock price information distribution service, it is necessary to perform user registration in the securities company server 30. When a service use application is made, data for user authentication is registered for each user. Specifically, a customer number and a login password are registered in the customer information storage unit of the securities company server 30.

  Furthermore, the user terminal 15 is used to register a brand for which the user wishes to distribute stock price information. Specifically, the user terminal 15 is used to log in to the securities company server 30 and apply for a stock name for which distribution of stock price information is desired. In this case, the securities company server 30 generates a user brand list and stores it in the user brand list information storage unit 32. In this user brand list, data relating to a brand code designated by the user is recorded in association with a customer number that identifies a user.

(Stock price information display program startup process)
Next, the starting process of the stock price information display program will be described with reference to FIG.
When using the stock price information distribution service, first, a browser program stored in the mobile phone terminal 10 is activated. Then, the securities company server 30 is accessed. In this case, an initial screen for login is displayed on the display unit of the mobile phone terminal 10. This initial screen includes input fields for the customer's customer number and login password.

When the setting of the customer number and login password input fields is completed, the mobile phone terminal 10 transmits a login request to the securities company server 30 (step S1-1). This login request includes the customer number set in the input field and authentication data related to the login password.

  Having received the login request, the securities company server 30 executes user authentication processing based on the received authentication data (step S1-2). Specifically, the securities company server 30 confirms whether or not the received customer number or login password is registered in the customer information storage unit. Since the received customer number and login password are not registered in the customer information storage unit, when the user authentication cannot be completed, the mobile phone terminal 10 is notified of this. On the other hand, when user authentication is completed, the securities company server 30 transmits login screen data.

  Then, a login screen is output on the display unit of the mobile phone terminal 10. This login screen includes a use selection button for the stock price information distribution service. When this use selection button is selected, the mobile phone terminal 10 starts a stock price information display program (mobile terminal side application) stored in the program storage unit. If the stock price information display program is not stored in the program storage unit, the download site is accessed and the stock price information display program is downloaded.

  Further, the mobile phone terminal 10 transmits a service use request to the securities company server 30 (step S1-3). In this case, the securities company server 30 searches the user brand list based on the customer number for which user authentication has been performed. Then, the securities company server 30 transmits a user brand list for brands registered by the customer to the mobile phone terminal 10 (step S1-4). The mobile phone terminal 10 records the received user brand list in the memory.

  When the stock price information display program is activated, the mobile phone terminal 10 is always connected to the stock price information distribution server 20 by TCP / IP. A main menu screen 500 shown in FIG. 5 is output on the display unit of the mobile phone terminal 10. The main menu screen 500 includes a “stock price inquiry” button, a “registered brand” button, an “index list” button, a “market condition overview” button, a “stock ranking” button, and the like. Furthermore, an end button, a connection status display field, and a menu button are included.

  When the “stock price inquiry” button is selected, a stock price inquiry screen 510 shown in FIG. 5 is output to the display unit of the mobile phone terminal 10. When a keyword is specified in the search input field of the stock price inquiry screen 510 and the “Search” button is selected, search candidates are output. And a board information screen and a chart screen can be outputted.

  When the “index list” button is selected, an index list screen 520 shown in FIG. 5 is output to the display unit of the mobile phone terminal 10. On this index list screen 520, various major indices are output for stocks. In addition, when the “market status overview” button and the “stock ranking” button are selected, a market status overview screen and a stock ranking screen are output to the display unit of the mobile phone terminal 10.

  When it is desired to acquire the stock price information of the registered brand, the “registered brand” button on the main menu screen 500 is selected. In this case, the mobile phone terminal 10 transmits a request for registration of the brand registration list to the stock price information distribution server 20 (step S1-5). This registration request includes data relating to a terminal identifier for identifying the user's mobile phone terminal 10. Based on this terminal identifier, the session between the stock price information distribution server 20 and the mobile phone terminal 10 is maintained. Further, the registration request includes information on the brand code generated based on the user brand list acquired from the securities company server 30. Therefore, the brand for which distribution of stock price information is desired is specified by this brand code.

  The stock price information distribution server 20 that has received the registration request executes the registration process of the brand registration list (step S1-6). Specifically, the control means 21 of the stock price information distribution server 20 records a brand registration list including a brand code in the brand registration list storage unit 22 in association with the terminal identifier.

Then, the control means 21 acquires the stock price information recorded in the stock price information storage unit based on the brand code included in the brand registration list (step S1-7).
Next, the stock price information distribution server 20 transmits the stock price information of the brand corresponding to the brand registration list to the mobile phone terminal 10 (step S1-8). Specifically, the control means 21 of the stock price information distribution server 20 generates registered brand display screen data including stock price information for one page to be displayed on one screen of the display unit of the mobile phone terminal 10, and the mobile phone terminal 10 to send.

  In this case, the registered brand display screen 530 shown in FIG. 5 is output to the display unit of the mobile phone terminal 10 (step S1-9). Thereafter, when there is a request process for another page from the mobile phone terminal 10 (step S1-10), the stock price information distribution server 20 executes a process for transmitting the stock price information of the requested page (step S1-). 11). In this case, as described above, the session between the stock price information distribution server 20 and the mobile phone terminal 10 is maintained by the TCP / IP connection.

(Stock price information distribution process)
Next, stock price information distribution processing in real time will be described with reference to FIG.
The stock price information distribution server 20 accepts the distribution of new arrival information from the exchange system 40 (step S2-1). The stock price information includes information (new arrival information item) related to the stock code to be information. Then, the control means 21 of the stock price information distribution server 20 stores the received information in the stock price information storage unit.

  And the control means 21 performs the collation process of a brand (step S2-2). Specifically, the control means 21 searches whether the brand registration list including the brand code included in the information distributed from the exchange system 40 is registered in the brand registration list storage unit 22.

  When the brand registration list including the brand code of the distribution information is registered (in the case of “YES” in step S2-3), the control means 21 specifies the terminal identifier that maintains the session with respect to the brand registration list. Then, the stock price information is transmitted to the mobile phone terminal 10 (step S2-4). Specifically, the control means 21 acquires the latest stock price information and transmits it using a push protocol. In this case, the received stock price information is output to the display unit of the mobile phone terminal 10. Specifically, the mobile phone terminal 10 changes the display of the brand having the stock price fluctuation on the registered brand display screen 530 shown in FIG. When the brand registration list including the brand code of the distribution information is not registered (in the case of “NO” in step S2-3), the control unit 21 waits for reception of the next distribution information. The above processing is continued until the session with the stock price information distribution server 20 is disconnected or the program ends.

(Communication status monitoring process)
Next, communication state monitoring processing will be described with reference to FIG.
When such a stock price information distribution service is used, the mobile phone terminal 10 constantly monitors the connection state with the stock price information distribution server 20.

In this case, the stock price information distribution server 20 transmits a connection state confirmation signal (here, time data) to the mobile phone terminal 10 at regular time intervals (step S3-1). This time data is used as a signal for confirming the connection state. In the present embodiment, time data is transmitted by broadcast to all the mobile phone terminals 10 that are maintaining sessions with the stock price information distribution server 20.

The mobile phone terminal 10 receiving this time data records this time data in the memory (step S3-2).
Then, the mobile phone terminal 10 periodically monitors the time data recorded in the memory (step S4-1). Specifically, when receiving the time data, the mobile phone terminal 10 measures an elapsed time from the reception of the time data using a timer in the mobile terminal side application. Then, it is checked whether or not the next time data is received before a predetermined reference time elapses. When the next time data is received, the timer value is reset again and the elapsed time is checked. If the elapsed time exceeds the reference time, a communication error is assumed.

  In the case of communication abnormality (in the case of “YES” in step S4-2), the mobile phone terminal 10 outputs an alarm on the display unit (step S4-3). Specifically, “communication error” is output in the connection status display field of each screen (500 to 530). Then, a message “Connection is lost. Do you want to reconnect?” Is displayed and the user is prompted to connect to the mobile phone network again. If it is determined that reconnection is not required, the mobile terminal side application is terminated. When the user selects reconnection, the mobile phone terminal 10 is connected to the mobile phone network and connected to the Internet to connect to the stock price information distribution server 20. And the continuation of the process which the portable terminal side application was performing immediately before is performed. For example, if the second page of the registered stock list is displayed, all the stocks (up to 10 stocks) on the two pages are registered again in the stock price information distribution server 20, and the latest stock price data is received. The automatic update data is received whenever there is a change thereafter.

  However, in the case of a momentary interruption between the mobile phone terminal 10 and the base station 60 (mobile phone network), the radio wave state is recovered before communication abnormality occurs. In this case, the mobile phone terminal 10 automatically resumes communication with the base station 60. As a result, the TCP / IP always-on connection with the mobile phone terminal 10, the mobile phone network, the Internet, and the stock price information distribution server 20 is restored. In such a case, the user does not need to do anything, or the user is unaware of the instantaneous interruption of communication, and the connection is always restored by the TCP / IP of the mobile phone terminal 10 and the stock price information distribution server 20. It will be. This communication process is continued until the mobile terminal side application of the mobile phone terminal 10 is terminated (step S4-4).

As described above, according to the present embodiment, the following effects can be obtained.
In the above embodiment, the securities company server 30 includes the user brand list information storage unit 32. In this user brand list, information for specifying a brand that the customer desires to acquire stock price information is recorded. Information included in the user brand list is provided to the stock price information distribution server 20 via the mobile phone terminal 10 and recorded as a brand registration list. Then, the stock price information distribution server 20 collates the brand code included in the information delivered from the exchange system 40 with the brand registration list. When there is a registered brand, the stock price information is distributed to the mobile phone terminal 10. Thereby, the user can acquire the stock price information of a desired brand in a timely manner.

  The user brand list to the securities company server 30 can be performed in advance. The mobile phone terminal 10 places importance on mobility, and the operability is sometimes difficult compared to a normal personal computer or the like. Since the user brand list can be registered in advance, the user terminal 15 can be used for efficient registration.

In the above embodiment, the stock price information distribution server 20 that has received the registration request from the mobile phone terminal 10 executes registration processing of the brand registration list. Specifically, the control means 21 of the stock price information distribution server 20 records a brand registration list including a brand code in the brand registration list storage unit 22 in association with a terminal identifier for specifying the user's mobile phone terminal 10. To do. For this reason, on the stock price information distribution server 20 side, even if the terminal maintaining the session can be specified, the user (the customer of the securities company) cannot be specified. Therefore, information distribution and personal information can be managed separately.

  In the above embodiment, the brand registration list registered in the brand registration list storage unit 22 is recorded when a registration request is received from the mobile phone terminal 10. Then, it is deleted when the session with the mobile phone terminal 10 is disconnected. Thereby, the capacity load of the stock price information distribution server 20 can be reduced.

  In the above embodiment, a push protocol is used to transmit stock price information to the mobile phone terminal 10. For this reason, as shown in FIG. 6, it is possible to provide only the information that has changed while reducing the lime lag. In particular, in order to provide information to the mobile terminal, the latest information can be acquired as long as the mobile terminal side application is activated. Therefore, a timely transaction can be performed.

  Further, the stock price information distribution server 20 transmits time data to the mobile phone terminal 10 at regular time intervals, and the mobile phone terminal 10 periodically monitors the time data recorded in the memory. When the time interval is abnormal, the mobile phone terminal 10 outputs an alarm on the display unit. In TCP / IP connection using a mobile phone terminal as a client, TCP / IP with the Internet in the mobile phone network is able to continue without disconnecting the TCP / IP session even if communication interruptions due to radio interference occur. The connection can be maintained regardless of the communication state in the physical layer with the terminal. That is, since the physical error state is not notified to the TCP layer, the communication state may not be grasped. With the alarm output, it is possible to grasp the communication state and determine whether the current stock price is the latest.

  Further, in this case, the stock price information distribution server 20 only transmits time data at regular time intervals, and there is no communication such as a request and a response. For this reason, the communication amount can be reduced.

In addition, you may change the said embodiment into the following aspects.
In the above embodiment, the securities company server 30 includes the user brand list information storage unit 32 that stores the user brand list. Instead, the user brand list may be registered directly in the stock price information distribution server 20.

  In the above embodiment, it is assumed that a stock price information distribution service is provided in which information on stock brands desired by the user is provided to the user's mobile phone terminal. The information provided is not limited to stock price information. It can be applied to information on exchange rates and weather forecasts. For example, in the case of currency exchange, “country name” is used as an item to be received in real time, and in the case of weather forecast, “location name” is used.

  In the above embodiment, when the time interval is abnormal, the mobile phone terminal 10 outputs an alarm to the display unit. The alarm output method is not limited to this, and any alarming method may be used as long as it can alert the user. For example, an alarm sound may be output.

In the above embodiment, since the mobile phone terminal 10 constantly monitors the connection state with the stock price information distribution server 20, the stock price information distribution server 20 transmits time data to the mobile phone terminal 10 at regular time intervals. Then, the mobile phone terminal 10 confirms whether there is no abnormality in the time interval of the received time data. The confirmation of the communication state is not limited to this. For example, the mobile phone terminal 10 can periodically transmit a request and check the communication state based on a response from the stock price information distribution server 20.

  In the above embodiment, since the mobile phone terminal 10 constantly monitors the connection state with the stock price information distribution server 20, the stock price information distribution server 20 transmits time data to the mobile phone terminal 10 at regular time intervals. Instead, the stock price information distribution server 20 may send a connection state confirmation signal (for example, time data) after a predetermined time has elapsed from the last transmitted data. In this case, the mobile phone terminal 10 records the reception time of the last received time data or push data. Then, even if a predetermined time elapses from this reception time, an alarm is output if there is no reception from the stock price information distribution server 20. Thereby, when push data is frequently sent, transmission of a connection state confirmation signal can be omitted. As a result, the traffic volume can be reduced.
