The present invention relates to a method and apparatus for receiving securities information using a wireless call network. In particular, when a holder of a wireless pager capable of receiving text calls a business operator and requests a subscription to a securities information service, stocks for each company are provided. The wireless caller, who always obtained the information from the securities company and stored it as a database in the Hangul Servo, sends out stock information about all the companies to the public at predetermined intervals, so that the pager holder does not have to go to the securities company. The present invention relates to a method and apparatus for receiving securities information using a wireless call network so that a company can easily know the securities information of a desired company.

The existing pager is configured to receive only the contents transmitted by letters or numbers from a specific person, and securities investors are not equipped with any function to receive and display additional services such as stock information. The invested stock information was unknown.

In other words, subscribers who have a wireless pager who can receive text messages cannot receive any service for securities information, so they can go directly to a brokerage firm, make a phone call to a securities company, or connect an information provider to a personal computer. I could only see it through the monitor.

It is an object of the present invention, when a wireless calling subscriber calls a service provider and issues a service request for securities information, a wireless call that obtains stock information for each company from a computer of a securities company and stores it as a database in a Hangul servo. The operator keeps the latest stock information of all companies sent to the public at predetermined time intervals, so that the holder of the pager can easily know the contents of the company's securities transactions whenever and wherever. The present invention provides a method and apparatus for receiving information.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a general wireless calling network to which the present invention is applied, and comprises a terminal 1 for creating a predetermined sentence and transmitting the DTMF tone through a telephone line; A public telephone network (2) for transmitting DTMF tones for a predetermined sentence transmitted from the terminal (1) to a radio call exchanger (3); A wireless call exchanger 3 performing overall control functions according to a wireless call and securities information service; A voicemail box 4 for outputting announcements for predetermined modes; A stock information database unit 8 which continuously transmits various stock information which changes every moment to the Hangul server 5 of the wireless calling provider side; A Korean server which stores and stores various data transmitted through the public telephone network 2 or transmitted from the stock information database unit 8 and outputs it upon request of the wireless call exchanger 3 ( 5) and; A transmitter (6) for transmitting various data outputted through the radio call exchanger (3) to the air; It consists of a receiver (7) for receiving the various data transmitted from the transmitter (6).

2 is a block diagram of the receiver 7, that is, the wireless pager, which is the apparatus of the present invention, and receives various wireless call signals through the antenna 70, including the central volume information periodically transmitted every predetermined time. An RF receiver 71 for receiving and amplifying only a radio call signal of a predetermined frequency band (for example, 322-328 MHz) to a predetermined level; A decoder (72) for detecting only desired data from a carrier signal in a radio call signal output from the RF receiver (71); A microcomputer (73) performing overall control of the pager through a predetermined program; A load driver 74 for selectively driving the buzzer 74A or the diaphragm 74B when there is a wireless call under the control of the microcomputer 73; A display unit 75 for selectively displaying a current time, a call number, and various kinds of information under the control of the microcomputer 73; A key input unit (76) having a call number search key or the like and selectively operated by a user; In the wireless pager composed of a predetermined control program and EEPROM (77) for storing various data on the Hangul font, the key input section (76) selects a general calling mode, including securities information, or enters a code for a desired company. The mode selection key 761 used to increase the city number, the select key 762 used to change the number of digits when entering a code for the desired company, and the stock information for the predetermined company are selected from the SRAM 78; A stock information call key 763 is added to read the data, and the microcomputer 73 stores the stock information of each company, which is sent out every predetermined time, in the order of new data, and then returns the user's stock information call key 763. When there is an operation, the SRAM 78 outputs the stock information of the desired company to the microcomputer 73, and the key is input by the user under the control of the microcomputer 73. The code value for each company is memorized, and when the user's securities information call key 763 is manipulated, the code for the desired company is outputted to the microcomputer 73 so that the microcomputer 73 stock information of the corresponding company. It is characterized by the addition of a ROM 79 that can be recalled from the SRAM 78.

On the other hand, in the method of the present invention, as shown in FIG. 3, when the POCSAG signal is received in the standby state after the power is turned on, the received control code is *? And the stock price control code * $ and Check the transaction volume control code * + in sequence and process it as a general message unless it is a control code, but the listed company control code * ?, the stock price control code * $ and the volume control code * + are normal. If it is sequentially received, the transaction information for the stock items of the company selected by the subscriber is displayed on the display unit 75 and at the same time characterized in that the process of storing in the SRAM (78).

Referring to the effects of the present invention as follows. First, a subscriber with a wireless caller capable of receiving text, i.e., a receiver 7, makes a call to a wireless call provider through a terminal 1 such as a telephone or a personal computer connected to a public telephone network 2, or visits himself by visiting himself. When a request for a predetermined ticketing information service is performed together with a password of the wireless calling service provider, the wireless calling service provider performs a joining procedure for performing the securities information service for the corresponding wireless calling subscription number.

In addition, the terminal installed in each securities company, that is, the securities information database unit 8 continuously updates the securities information of each company that changes from time to time and transmits it to the Hangul server 5 of the wireless calling company side and at the same time new listing. If there is a company or the like, it is immediately registered and the stock information of the company is continuously stored. Therefore, new securities data is always stored in the Hangul server 5 of the wireless call provider.

On the other hand, the wireless call exchanger 3 reads the stock data of each company changed at intervals of a predetermined time (for example, 10 minutes) from the Hangul server 5, converts it into a code value, and then transmits the air through the transmitter 6 to the public. In order to transmit the data, the holder of the receiver 7 such as a radio pager (of course, the person who applied for the stock information service) can receive various kinds of information on the stock of the desired company at predetermined time intervals.

Of course, in the case of a wireless calling subscriber who has not gone through the above procedure, even if the stock information is transmitted to the public at predetermined time intervals, the reception is not possible.

In addition, the receiver 7, i.e., the pager, stores an SRAM 78 for storing new stock information of each company in an existing pager, and a ROM for storing code values for each listed company that the user wants to service. At the same time, the key input unit 76 includes a mode selection key 761, a select key 762 which can change the number of digits when a code is input for the desired company, and the SRAM 78 of the stock information of the predetermined company. And a stock information call key 763 for selectively reading from the data.

Therefore, when the user receives the stock information of each listed company through the receiver 7, the user can select and receive only the stock information of the desired company, as well as the stock of each listed company stored in the SRAM 78 at any time. The transaction details can be known through the receiver 7.

That is, the holder of the receiver 7 which makes a request for the stock information service to the wireless calling service provider selects the stock information service mode through the mode selection key 761 provided in the key input unit 76, and then again the mode selection key 761. ) And the select key 762 are properly operated to sequentially input code values for listed companies (for example, five companies) that the user wants to know, and the receiver 7 is sent out to the air at predetermined intervals. Among the stock information of hundreds of listed companies (for example, 1800), only the stock information of listed companies having the key value coded above is displayed and displayed on the display unit 75 so that subscribers can see them directly. At the same time as the zoom, it is stored in the SRAM 78 so that it can be displayed when a subscriber requests it later.

Of course, the stock information for the listed companies received above is displayed in the order that the control code is input in the earliest order, and the stock information of the listed companies in the following order in response to the number of the user operating the select key 762. Stock information of each listed company, which is displayed on the display unit 75 and stored in the SRAM 78, is called and displayed sequentially when a user's key operation is performed. Input of the control code of the listed company that wants to receive the securities information service is as follows.

First, when the securities information service mode is selected through the mode selection key 761 provided in the key input unit 76, a predetermined number of characters may be input on the display unit 75 to input a code for a listed company. If any number of digits is selected in this way, the desired number is selected by pressing the mode selection key 761 an appropriate number of times, and then, the select key 762 is used to select the next digit and the mode selection key 761 is operated. The control code can be input by repeating the method of selecting a desired number.

On the other hand, the receiver 7 receiving various securities information sent from the wireless calling operator at predetermined time intervals continues to detect whether a POCSAG signal is received from the operator when the power is turned on and in the standby state. When the explosive signal is received for a predetermined time, the control code received initially detects * ?, which indicates a predetermined listed company control code, and processes it as a general message. If the code is * $, then it is also checked if it is not * $. If it is * $, it checks whether the received control code is * + indicating the transaction volume. If it is * +, the control codes are all matched and the stock information of the first listed company is displayed. At the same time as shown in (75) all stock trading information in a publicly traded company with a control code, the user enters and stores in the group SREAM (78).

Therefore, the wireless calling subscriber can keep track of the latest stock information through his wireless pager, that is, the receiver 7.

That is, as soon as stock information is sent out and received, the key input unit 76 can be manipulated appropriately to find out the stock information of the listed company that the user wants, and each listing stored in the SRAM 78 at any time even after the delivery time. You can find out the stock information of companies.

On the other hand, Figure 4 is a diagram illustrating the type of control code used in the present invention, Figure 5 is a diagram showing the contents of the securities information appearing on the display unit 75 and the contents for interpreting them according to the present invention.

For example, a control code and a number appearing on the display unit 75 are shown in FIG. Suppose that 18520 1-8 * $ 12000 * + 15000, this is the stock of CheilJedang (which, of course, is decided), its current share price is 12,000 won, its trading volume is 15,000 shares, and the reception time was previously Appears as the time when the call was received (eg, 12:00).

As described above, according to the present invention, when a wireless calling subscriber calls a service provider and issues a service request for securities information, the wireless calling service provider obtains stock information for each company from the computer of the securities company in the Hangul Servo. If the database is stored in the database and the latest stock information of all the companies is continuously sent to the public at predetermined time intervals, the subscriber's receiver receives and displays only the stock information of the listed company, which is stored at the same time. The pager holder is a very useful invention that can easily know the contents of a company's securities trading anytime and anywhere.
