Description

Real-time financial information system using personal mobile terminal {A REAL-TIME FINANCIAL INFORMATION SYSTEM USING PDA}

The present invention is a real-time financial information system using a personal mobile terminal relates to a system for providing users with securities information, such as ticker inquiry, securities news, etc. through the Internet network.

The conventional stock trading system using a wireless dedicated terminal is a short message service (SMS; Short) using a dedicated wireless terminal for a stock trading wireless service on stock information such as stock quote inquiry, stock market news, and stock of interests desired by the user. It is a two-way data information transmission method of Message Service method, which installs its own base station and requests information such as quotation from the terminal owned by the user, and then connects to the service company server through the base station near the terminal and back to the securities company server. Called back and sent back to the user to the reverse path (see Figure 1).

However, the securities trading system according to the prior art can enter an account, password, item code, price, etc., as long as there is no failure of the system due to the congestion of the order, it is possible to place the order immediately, and also check the execution history of the order. In addition, you can check the price analysis data, look up the stock market breaking news, the current price of about 20 related items, the degree of fluctuation and trading volume compared to the previous day, and the current price of the relevant item. If you press the loading button every time you can see the predetermined data to see the data changes in real time without the operation of the terminal was impossible, the terminal does not have an operating system (operating system) for operating the terminal to display a plurality of windows Can only display simple text-based information, Miscellaneous analysis was not only possible on the terminal itself, but also the securities information service area was limited, and nationwide service was impossible. In addition, there was a drawback that the installation cost of the base station is very large for the service.

On the other hand, as shown in Figure 2, the securities trading system using a smart phone according to the prior art is a communication device that combines a digital mobile phone, a portable personal computer, a personal digital assistant (PDA), wireless data communication, etc. The company has used securities trading services through the Internet using smartphones that can make phone calls and are compatible with personal computers. The securities trading system using a smart phone adopts a method similar to the securities trading system shown in Fig. 1, and is a securities trading system based on a two-way securities data transmission method of a short message system. When requesting the request to the securities company server via the base station of the mobile communication network operator near the terminal was adopted to load a predetermined data to the user.

Therefore, the securities trading system using the smart phone according to the related art shown in FIG. 2 has the effect of providing not only current stock trading but also information such as balance inquiry, current price, and stock of interest, and can be used nationwide. While the screen has a wider advantage compared to the WAP Phone (Wireless Application Protocol), the stock information such as the stock price or stock news that changes in real time cannot be immediately delivered to the user of the terminal, that is, it is not updated. Not only does not have a big disadvantage, as in the securities trading system shown in Figure 1, it is not possible to open a plurality of windows, complex analysis of charts and graphs was impossible, and even if the connection is nationwide, there was a domestic limit.

Therefore, the object of the present invention is to compensate for the disadvantages of the prior art by using a personal mobile terminal to provide users with stock information such as quotes, stock news, etc. in real time, as well as analysis of stock data and charts. It enables analysis of graphs, etc., and can open a plurality of windows so that users can view the information they want through different windows, and can provide not only stock quotes but also futures and options information to users in real time. It is to provide a real-time financial information system using personally available mobile terminals that can be used for portfolio investment between futures and cash.

Hereinafter, a real-time financial information system using a personal portable terminal according to the present invention will be described in detail.

3 and 4 illustrating a real-time financial information system using a personal portable terminal, there is a personal digital assistant (PDA) equipped with a wireless modem. The personal mobile device is equipped with a program (or MP Traveler) that can be installed only on the device. First, when the terminal is switched on and the program is clicked, the program is operated so that the first screen showing the service connection is displayed on the LCD as shown in FIG. At this time, if you click the service access key on the initial screen, you can connect to one or more authentication servers, service server and database server via the wireless communication network server of one or more mobile operators through the wireless modem installed in the PDA. Connect to the configured Market Point server. The market point server already stores real-time securities information, so that when the user approves the ID and password provided through the program installed in the personal digital assistant (PDA) through the authentication process in the authentication server, the predetermined stock information data is given to the user. It is provided to a personal digital assistant (PDA) through a road so as to be displayed on the initial screen after connection as shown in FIG. When the initial screen is displayed on the personal digital assistant (PDA), when a user clicks a predetermined button such as a stock button or a gift button, a predetermined stock in a plurality of windows through a program installed in the personal digital assistant (PDA) as shown in FIG. Display information.

Meanwhile, although only a predetermined button is illustrated in FIGS. 4 and 5, a button for displaying or analyzing predetermined stock information may be added.

To terminate the connection, the user clicks the end button on the initial screen shown in FIG. 4 to terminate the service via the above-described path.

Next, a flow of operations and control of a program installed in a personal digital assistant (PDA) constituting a real-time financial information system using the personal digital assistant of the present invention will be described with reference to FIGS. 6 and 7.

In order to help the understanding of the present invention, the server will be described before explaining the flow of operation and control of the program.

The server part can be largely divided into an authentication server that manages a user's access, and a service server that transmits real-time stock quotes to a user and handles a user's inquiry request.

Multiple authentication servers and service servers can be installed, and each server can exchange user's connection status and the number of users connected to the service server according to a predetermined protocol. It is configured to keep it in a state.

The service server uses the multi-threading method for user processing, and creates a large number of threads in advance at the start of a program and puts them in a standby state. When the user wants to terminate and the user wants to terminate, the thread waits again. This is called a thread pool method that creates and manages multiple threads.

First, when a program installed in a personal digital assistant (PDA) operates, the item information data which is already stored is read, displayed on the terminal, and the telephone is connected (step 1). Then, the unique user ID and password already assigned are sent to the authentication server (step 10). The authentication server, which has received the user ID and password, is checked in the user management database. If authentication is not allowed, the authentication server is placed in a standby state (step 20). At the same time, the authentication server creates a special key value and transmits it to the service server, while at the same time, the program in the personal mobile terminal, that is, the service server to be connected to the user. It tells the address of (step 30). The authentication step is then completed (step 40).

The user then accesses the address of the service server with the key value received from the authentication server (step 50). Since the key values are always the same, the service server can correctly identify the user when connecting. Therefore, in step 50, when the service server receives a message from the authentication server that the user will connect, the service server wakes up one of the waiting threads in the thread pool and prepares the user for connection. By determining whether it is the same as the key value received from the authentication server to determine that the user has been authenticated (step 60). If the key values are the same, the thread that was in the service server wait state is connected to the user from this point on, and this thread handles all user requests.

Then, the data synchronization processing step between the user and the service server proceeds (step 70). That is, when the user access is completed in step 70, since the personal portable terminal possessed by the user has basic information (item code, item name, etc.) about the item, the stock information of the data is different between the user and the service server. Therefore, data synchronization is required between the user and the service server. This is to handle synchronization in order to reduce the load on the communication and service server that occurs when the user first accesses or requests for stock information such as stocks after being connected, and to allow the user to easily use and access information quickly. As a result, in step 70, when the last reception date of the item information received by the user is transmitted to the service server, the service server determines whether there is any item information added, deleted or modified since the user's last reception date, so that only the changed contents are transmitted to the user. In turn, the data is synchronized between the user and the service server with minimal traffic.

When the data synchronization processing step (step 70) is finished, the data on the personal digital assistant (PDA) and the data held by the service server become the same value. From this time, if the user inputs a predetermined button or item code, the request data processing step The process proceeds to step 80. That is, in step 80, when the user transmits the transfer number and the corresponding transfer processing condition to the service server according to the screen or the user's operation according to the predefined program, the thread assigned to the user sends data corresponding to the transfer condition to the database server. Inquiry from the memory inside, transmit to the user in a predefined format, and outputs the data received by the program of the personal digital assistant (PDA) on the screen while the user blinks on the screen to recognize the data received do.

Then, the real time data processing step (step 90) proceeds.

An important part of the configuration of a service server system is the data processing technique. To handle this part, the server system has a global memory accessible to all threads and a data processing thread that receives data and sends it to each user processing thread. have. In global memory, each item's information, current price, quotation, transaction volume, etc., is updated every time the price is changed by the data processing thread, and all user processing threads can refer to this memory area.

Therefore, in the real-time data processing step (step 90), the data processing thread receives data from an external data source, and transmits data not limited to a specific item such as news or public announcements directly to the user processing thread, Similarly, the price data related to the item is compared with the corresponding item data in the global memory described above, and then the global memory is updated and the final data of the changed part is created. Each user processing thread sends this data to the user. Step proceeds (see FIG. 7). Instead of sending all the quotes to the user, only the changed parts are sent, which reduces the communication load and the user's processing load.

Using a real-time financial information system using a personal mobile terminal according to the present invention can obtain the following effects.

First, the financial information system according to the present invention has the effect of providing real-time financial information to users for the first time in Korea by updating the data whenever the stock information changes in real time and providing the stock information wirelessly to the user's terminal. .

Second, the financial information system according to the present invention provides an effect that can be used not only in Korea but also abroad.

Third, the financial information system according to the present invention analyzes the data provided in real time through a program installed in the terminal and provides the user with predetermined information by using a graph or a chart.

Fourth, since the financial information system according to the present invention uses the Windows operating system, there is an effect of providing predetermined stock information to the user through a plurality of windows that have not been previously seen.

Fifth, the financial information system according to the present invention provides users with stock information of not only the spot market but also the futures market, thereby enabling the portfolio investment to the user.
