Description

Real-time information service method in wireless communication system {METHOD OF REAL-TIME INFORMATION SERVICE IN WIRELESS TELECOMMUNICATION SYSTEM}

The present invention relates to a method for real-time information service in a wireless communication system and a computer-readable recording medium recording a program for realizing the same. In particular, the present invention relates to go information, sports information, stocks, and the like in a wireless communication system such as a high-speed wireless call system. The present invention relates to a real-time information service method for providing a subscriber with a large amount of information that changes in real time, such as information, and a computer-readable recording medium having recorded thereon a program for realizing the same.

In general, as the wireless call service develops, text and multimedia broadcasting services using the wireless call network are actively progressing.

However, in the conventional information service using a wireless call network, Korean, English letters, numbers, and the like are broadcast using an information code to a common address of an information terminal. The address structure of such an information terminal is shown in Table 1 below.

address Usage 0 Personal address One Personal Wide Area Address 2 3 Common Address (Used by Each Provider) 4 5 6 Information address # 0 7 Information address # 1 8 Information address # 2 9 Information address # 3 10 Information Address # 4 11 Information Address # 5 12 Information address # 6 13 Information address # 7 14 Information address # 8 15 Information address # 9

Referring to (Table 1), the information item selected by the subscriber is broadcasted to one of the addresses between information addresses # 0 to # 9, and is received by the terminal and displayed on the screen. In this case, the broadcasted information has a structure as follows to facilitate the subscriber to classify and manage the information.

Information address (Capcode) Information code Information content (Korean, English, numbers)

Here, the information code is a classification code indicating the type of information selected by the subscriber.

The paging switch selects one of the addresses between information addresses # 0 to # 9 and selects the information code (English and numeric combinations) and the information content (Korean and English numeric combinations) to be displayed on the terminal screen. It is configured in the specialized form as shown and transmitted to the terminal.

After that, the terminal having the corresponding information address receives the full message and classifies the full text according to the information code and stores the full text in a storage location in the terminal. At this time, the subscriber can check the contents of the received message by selecting the classification code.

However, in the conventional information service method as described above, since the terminal receives the full text in the form of Korean, English, and numbers, the amount of data of the full text transmitted from the exchange to the terminal over the airwave is very large, and the transmission time is prolonged in proportion. However, there was a problem that a large amount of data cannot be serviced in real time because of a reception delay time. For example, in order to express "1024", 4 bytes are required to be transmitted in the above-described manner. However, if only 10 bits are used, binary data can be represented in binary. There was a problem falling.

The present invention has been made to solve the problems described above, real-time information for providing a subscriber in real time without a transmission delay a large amount of information, such as stock information in a wireless communication system such as a high-speed wireless call system It is an object of the present invention to provide a computer-readable recording medium recording a service method and a program for realizing the same.

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.

1 is an exemplary configuration of a wireless call system to which the present invention is applied.

The TDX-PS 14 receives a signal through a Public Switching Telephone Network (PSTN) and processes station number classification, subscriber management, and subscriber service type.

A radio calling terminal (APS: Advanced Paging System) 13 encodes a radio call according to a radio call signal. In this case, when the voicemail box 15 is to be used, the voicemail box 15 additionally installed in the wireless call exchanger 14 may be used.

In general, the radio call signal is classified into a POCSAG (Post Office Code Standardization Adversary Group), a flex (FLEXible).

The signal generated by the radio calling terminal 13 is transmitted to the radio calling base station 12 and transmitted to the radio calling terminal 11 using airwaves.

There are three major types of wireless paging service.

The first is an optional local service, which is a method of selecting a mobile area from the system and the wireless calling terminal 11 whenever the subscriber moves to the corresponding area.

The second is a multi-region service, which transmits two or more regions at the same frequency so that two or more regions can be continuously serviced without switching between the system and the wireless calling terminal 11.

The third is a whole area service using a single frequency, which is a method of receiving services continuously regardless of the subscriber's mobile area.

Looking at the operation of the wireless call system as described above in detail.

First, a user enters a wireless call number into a subscriber input device such as a general telephone or a mobile phone to access a wireless call system through a public switched telephone network (PSTN). At this time, the user is first connected to the radio call exchanger 14.

All radio calls are entered into the radio call exchanger 14 and the appropriate action is taken by the radio call exchanger 14. The radio call exchanger 14 processes station number classification, subscriber management, subscriber service types, and the like, to the radio call terminal. Transfer to (13). At this time, the wireless call exchanger 14 distinguishes whether it is a POCSAG method or a FLEX method by using a connected radio call.

The wireless call terminal 13 processes a main control unit (MCU) and subscriber functions in charge of call processing and a high-speed paging controller (HPC) that converts the protocol into a protocol suitable for wireless call signaling. It consists of.

Here, the main control unit (MCU) is a part for managing a database for storing various types of information including subscriber information, and connects the subscriber with the voicemail box 15. Therefore, when the subscriber and the voicemail 15 are connected, the subscriber's information is input according to the voicemail addition item scenario. Thereafter, when the information input is completed, the main control unit (MCU) transfers the input information to the high-speed radio call controller (HPC).

Next, the high speed radio call controller (HPC) encodes the radio call according to the radio call signal according to a defined protocol and transmits the radio call to the radio base station 12. Thereafter, the radio calling base station 12 transmits the encoded radio calling call to the radio calling terminal 11 using the airwaves.

Finally, the radio calling terminal 11 receives the encoded radio calling call and processes the call separately.

In this embodiment, we propose a service method of a large amount of stock information that changes in real time in a high-speed wireless call system. This will be described in more detail as follows.

In order to provide a large amount of stock information that changes in real time using a wireless call network, an information providing device (IP) 17 which provides stock information, and receives and receives the wireless call exchanger 14 and the wireless call terminal 13. And an information server 16 for providing to the wireless calling terminal 11 through a high speed wireless calling network composed of a wireless calling base station 12 and the like.

The information providing device 17 collects a large amount of information that changes in real time such as stock information, converts it into a specific data format, and provides it to newspapers, broadcasters, telecommunication operators, and the like through the Internet.

As described above, in the present embodiment, it is assumed that a large amount of stock information that is changed in real time in a high-speed wireless calling system is provided to the subscriber, but in addition to such stock information service, life information such as sports, Go, and other entertainment information is provided. It is also possible to configure so that, in this case, it should be apparent that the same as the present embodiment. In addition, in the present embodiment, in addition to such stock information, a lot of living information is used in a commercial wireless communication system such as cellular, personal communication system (PCS), and trunked radio system (TRS). It may also be configured to be serviced through a broadcast type information service or a short message service (SMS), and in this case, it should be apparent that the same as the present embodiment.

In one embodiment of the flow of information packet transmission and reception of the real-time information service method according to the present invention, by transmitting the real-time stock information provided by the information providing device 17 from the radio call exchanger 14 to the radio call terminal (11) The radio call terminal 11 shows a procedure for processing the received stock information.

As shown in FIGS. 2A and 2B, in the real-time information service method according to the present invention, when a large amount of stock information to be transmitted is received in real time from the information providing apparatus 17 (201), the wireless call exchanger 14 is provided. Compresses the received stock information through various methods (202, 203).

In this embodiment, in order to guarantee real-time, a plurality of pieces of information are contained in the same capcode, and a plurality of capcodes are assigned to adjust the transmission time delay to be minimum. At this time, the number of cap codes is allocated in consideration of the necessary transmission rate.

In the present embodiment, the stock quote information is represented in a binary number form as a compression method most suitable for increasing transmission efficiency in the stock quote service. For example, in order to express the price or quantity of the stock price, the current price, the trading volume, the quotation, etc., it is expressed as a binary bit instead of an ASCII type number. That is, in order to express "1024", although it was conventionally expressed as 4-byte information in the form of "1", "0", "2", and "4", since it expresses in binary form of "10000000000" in this embodiment, Only 11 bits are needed.

The information compressed using the binary form or any other method cannot transmit the binary form as it is due to the characteristics of the wireless call exchanger 14, but needs to be converted back to ASCII form (204 and 205). In other words, in order to obtain the greatest compression effect, the transmission data is optimally converted into a binary form in units of 7 bits.

Of course, if the transmission technology of the binary form is equipped in the wireless call exchanger 14, it is obvious that the process of converting to the ASCII form is not necessary.

The process of converting the binary form to the ASCII form is to divide the binary bit string by 7 bits, and allocate the divided 7 bit bits to the byte having the most significant bit (MSB) of 0. For example, when the bit string is "10000000000101", when divided, it is divided into "01000000" and "00000101". Therefore, when receiving these two bytes, the receiving side may delete the most significant bit (MSB) and merge and analyze the two bytes.

Thus, after the conversion process, the head of the packet is added with the string of bytes output to configure the packet to be transmitted (206), and then transmitted to the radio call terminal 11 (207).

Subsequently, when the packet is received through the high-speed wireless call network (208), the wireless call terminal 11 restores the original stock information through the inverse conversion process of the conversion and compression performed by the wireless call exchanger 14. The reconstructed stock information packet is analyzed (213) and stored in the internal memory area (214). Thereafter, according to the subscriber's request, the current price of the stock is displayed on the screen in real time (215).

As described above, the present invention converts and compresses information in a conventional simple text transmission method, minimizes the amount of data to be transmitted through a packet form, and restores the original data in the received terminal to form a character form. As shown on the screen.

Accordingly, the present invention can transmit a large amount of data in real time in unidirectional communication using narrowband frequencies such as radio calling and TRS, thereby providing a service utilizing the airwave resources to the maximum.

In the present embodiment, it is assumed that a large amount of stock information that is changed in real time in a high-speed wireless calling system is provided to the subscriber, but in addition to the stock information service, the service is provided by providing living information such as sports, Go, and other entertainment information. It may be configured to achieve the same effect, even in this case it should be seen that the same as the present embodiment is obvious. In addition, in the present embodiment, a lot of life information in addition to such stock information can be configured to achieve the same effect as the present embodiment by providing a broadcast type information service or SMS in a commercially available wireless communication system such as cellular, PCS, and TRS. In this case, it should be understood that the same as the present embodiment.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention has an effect of optimally converting a large amount of information that changes in real time, such as stock information, into a binary form, thereby increasing the compression effect and serving the terminal in real time.
