Description

Terminal and control apparatus for real-time stock information service and real-time stock information service method using the same {terminal and control apparatus for real-time stock information sevice and method of real-time stock information srevice using it}

The present invention provides a terminal and stock information control device for real-time stock information service in a communication network having a broadcast and two-way communication channel, a real-time stock information service method using the same, and a computer-readable recording program for realizing the method. It relates to a recording medium.

In general, the real-time stock information service using the wireless communication network was based on the one-to-one communication method between the subscriber terminal and the system. For example, you can register your interest items in the system and, if certain conditions are met, notify the system in the event format from the system to the terminal, or you can check the current status of the interested items in the form that the subscriber periodically checks the system through the terminal. there was. In this case, the user is inconvenient to inquire from the terminal to the system one by one, and the charges are excessive.

In another form of service, a service may be provided by broadcasting stock information to all terminals based on a broadcast type service such as a wireless call and receiving the same from the terminal. In this case, too, since only one-way communication is provided from the system to the terminal, there is a problem that recovery is difficult in case of an error in the transmission data.

1 is a diagram illustrating a network for a conventional stock information service, and illustrates a stock information service network through a mobile phone or a wireless data network.

As shown in FIG. 1, the conventional stock information service network includes a stock information control server 11 that provides stock information, and stock information provided by the stock information control server 11 in a mobile telephone network (or similar network). Terminal 13 for providing stock information to the subscriber through the terminal, and a short message service (SMS) server (or similar server) 12 for connecting the stock information control server 11 and the mobile telephone network. And the like.

The stock information control server 11 is a server that controls the provision of stock information, the conclusion of a contract, and the like, and interworks with a short message service (SMS) server 12.

The terminal 13 may inquire individual stock information in real time through the stock information control server 11 via the SMS server 12, or execute a contract if necessary.

In such a conventional stock information service network structure, the user must manually operate the terminal 13 to inquire the stock price, and there is a disadvantage in that it is inadequate to provide a service such as an electronic board of a securities company.

When the stock quote service is provided in the conventional stock information service network structure as described above, the flow of the stock information message and the control message is as shown in FIG. 2.

FIG. 2 is a flowchart illustrating a general stock information service process, and illustrates a control procedure for inquiring stock information or performing a closing service in the stock information service network of FIG. 1.

As shown in FIG. 2, the stock information service process is largely based on a message control procedure 2a in the case where it is necessary to control the terminal 13 from the stock information control server 11, and a stock tightening service in the terminal 13. In this case, it is divided into message control procedure (2b).

The actual stock information service does not have only two types of messages as described above, but is essentially a structure that provides a service by one-to-one communication between the stock information control server 11 and the terminal 13.

As described above, conventionally, by taking only one of the one-way or two-way communication channel in the stock information service, when using only the two-way communication channel, the user must query the stock information control server 11 from the terminal 13 one by one. Inconvenient work was involved and the fee was excessively consumed. In case of using only one-way communication channel, since only one-way communication is provided from the stock information control server 11 to the terminal 13, an error in transmission data occurs. There was a problem that was difficult to recover.

In order to solve the above problems, the present invention records a real-time stock information service method for real-time stock information service in a mobile communication system under one-way (broadcast) and two-way communication channel environment and a program for realizing the same. Its purpose is to provide a computer readable recording medium.

In addition, there is another object to provide a terminal for unidirectional (broadcast) and two-way communication channel for serving the stock information in real time.

In addition, it is another object to provide a stock information control device for unidirectional (broadcasting) and two-way communication channel for serving the stock information in real time.

The present invention is to provide a most convenient real-time stock quote service by supplementing all the disadvantages by combining the two-way only stock information service and one-way only stock information service.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a diagram illustrating a network configuration for a stock information service to which the present invention is applied.

As shown in FIG. 3, the stock information service network to which the present invention is applied is a network in which an existing two-way communication channel and a one-way communication channel (broadcast channel) are combined (as a mobile telephone network to be developed in the future, an IS-95C and IMT-2000 network). Stock quote services in real time. Such networks can be based on IS-95C-based code division multiple access (CDMA) mobile telephone networks, or wireless networks such as next-generation mobile telephone networks such as International Mobile Telecommunication (IMT-2000) and Universal Mobile Telecommunication Service (UMTS). It's a network.

As described above, the evolved network simultaneously has a unidirectional high speed broadcasting channel and a high speed bidirectional channel. The structure of the terminal 32 and the stock information control server 31 for providing a stock quote service in the evolved network will be described later.

Here, the broadcasting channel is a unidirectional broadcasting network, which broadcasts stock information of all stocks in real time. This is a one-way communication channel, through which the stock information is transmitted to all terminals 32 and used for common control of all terminals 32.

On the other hand, the bidirectional communication channel is a channel used to recover through the stock information control server 31 separately when the error information found in the real-time stock information received from the broadcast channel. In addition, the bidirectional communication channel is used to perform individual stock inquiry and execution services which are the characteristics of the conventional bidirectional communication channel.

The two-way communication channel individually communicates with the terminal 32 one-to-one, and is used for two-way control information communication, recovery of error information of a broadcast channel, transmission and reception of a broadcast channel encryption key, and the like.

As described above, a method for providing a stock quote service in an evolved network having a high speed broadcasting channel and a bidirectional communication channel will be described in more detail through each channel.

The broadcast channel is a channel that broadcasts unidirectionally to the terminal 32 in the evolved network and includes information that all the terminals 32 can receive at one time. Such information includes item price information for each item and control information (for example, new item registration, item deletion, protocol version information, etc.) for controlling all terminals 32 transmitted from the stock information control server 31 at once. . Since these messages are transmitted through a unidirectional broadcast channel, there is an advantage that all the terminals 32 can receive them at once. However, since these messages are unidirectional, it is impossible to process the terminal 32 that has received the error information. A complementary channel is a bidirectional communication channel.

The bidirectional communication channel performs a one-to-one communication between the stock information control server 31 and the terminal 32 like the conventional stock information service, and provides a stock signing service, a customized stock information service, and the like. Through this, selective re-receipt of error information generated in a broadcast channel can be performed.

In this selective re-receiving method, information is transmitted to all terminals 32 through a broadcast channel, and only the terminal 32 that has received error information can selectively re-receive, thus transmitting and receiving all information one-to-one. Traffic efficiency is much better than that.

4 is a flowchart illustrating an embodiment of a method for real-time stock information service according to the present invention, which shows a procedure for recovering through a bidirectional communication channel when an error occurs in information received through a broadcast channel.

Here, the stock quote information broadcasted in real time is the market price information for each item displayed on the electronic display board of the general securities company, or control information that is simultaneously sent to the terminal 32 when a new item appears in the stock market. The stock quote information is transmitted to the terminal 32 through the network evolved from the stock information control server 31 (401, 402). At this time, the terminal 32 receiving the stock quote information is used as it is if there is no error information, and if an error is detected by the error detection algorithm, it selectively requests retransmission of the corresponding information through the bidirectional communication channel (403,404). ). Then, the stock information control server 31 resends the information requested by the terminal 32 (405 and 406).

Of course, at this time, since the one-to-one communication, communication is performed only between the stock information control server 31 and the corresponding terminal 32.

Meanwhile, a stock information service similar to the existing service (see FIG. 2) may be provided by appropriately combining the broadcast channel and the bidirectional communication channel. Using this method, since the terminal 32 provides a service having a function similar to that of a securities company's electronic display board in real time, and simultaneously provides a service capable of two-way control such as fastening, it provides a subscriber and service by upgrading the real-time stock quote service. It will be a big boon to all operators.

In addition, the present invention proposes a mobile phone terminal 32 as shown in FIG. 5 and a stock information control server 31 as shown in FIG. 6 in order to realize a real-time stock service using the aforementioned broadcasting channel and a bidirectional communication channel.
