The present invention relates to a method for transmitting a terminal control packet in a wireless communication system and a computer-readable recording medium recording a program for realizing the same. In particular, a high-speed wireless calling system, a cellular mobile communication system, and a personal mobile communication In a wireless communication system such as a personal communication system (PCS) and a trunked radio system (TRS), the terminal can not only increase the use efficiency of the terminal through control messages but also prevent illegal use of information. A control packet transmission method and a computer readable recording medium having recorded thereon a program for realizing the same.

In general, as the wireless communication service develops, text and multimedia broadcasting services using the wireless communication 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 (random use of 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 with the corresponding information address receives the preamble and classifies the preamble according to the information code and stores the preamble 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 related art, there is no method for controlling the terminal by using the above specialized form to convey the contents of simple information. For example, in stock quotes and similar services that do not require the receipt of information at night, the stock market closes the terminal's continued monitoring of the address in Table 1 to extend the life of the terminal battery. If there is a need for a terminal control method that stops and operates in the morning when the stock market starts, none of these terminal control methods exist.

As described above, the conventional technology may be somewhat adapted to a structure for providing information in a short form, but there is a protocol problem in processing a large amount of data that changes in real time. Even if you use a lot of airwaves to solve the problem, the terminal's control function is insufficient, so it consumes a lot of battery, and even when the subscriber terminates or stops using it, the telegram broadcasted to the information address, which is a common address, is illegal. There was a problem that could be.

In order to solve the above problems, the present invention ensures scalability when changing and adding packet fields through a control message in a wireless communication system such as a high-speed wireless calling system, and also increases the use efficiency of the terminal. It is an object of the present invention to provide a computer-readable recording medium recording a terminal control packet transmission method and a program for realizing the same, as well as preventing illegal use of information.

The present invention guarantees scalability by notifying the terminal to the terminal through a control message when the size of each field is changed or when a new field is added when transmitting packet type information, and also introduces the advantages of packet communication to the terminal control. The terminal battery efficiency can be increased and service illegal use can be prevented, thereby increasing the use efficiency of the terminal.

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.

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 that provides stock information, and receives the wireless call exchanger 14, the wireless call terminal 13 And an information server 16 provided 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 the information to newspapers, broadcasters, telecommunications companies, and the like through the Internet.

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 the present embodiment, a variety of terminal control functions to increase the use efficiency of the terminal as well as to propose a way to prevent the illegal use of information. This will be described in more detail as follows.

In order to provide a terminal control function, the wireless call exchanger 14 must transmit a control packet such as terminal battery control, expandability control, illegal use prevention, etc. to the wireless call terminal 11 through the wireless call network. Looking at this in more detail as follows.

The radio call exchanger 14 determines what control is necessary and selects the type of control and transmits it to the radio call terminal 11.

For example, since the real-time stock information transmits the stock information only from the opening of the morning stock market until the afternoon closes, the wireless call terminal 11 determines whether to transmit the stock information at other times such as night or holiday. In order for the radio call switch 14 to transmit the terminal address monitoring interruption and operation control message to the radio call terminal 11 so that the air call terminal 14 does not need to continuously monitor the air waves, the radio call terminal 11 is configured to receive the air waves for subsequent data reception. Stop monitoring.

In addition, when the size of the information packet field is changed or a new field is added, the radio call exchanger 14 defines a format supporting a variable data field and a variable number of data to transmit an information packet field change control message to the radio call terminal ( 11) to ensure scalability of future information digits.

In addition, when it is desired to prevent illegal use of the service, the wireless call exchanger 14 may prevent the illegal service use by transmitting the validity period of the service use to the wireless call terminal 11 through an illegal use monitoring control message. .

As described above, in the present embodiment, it is assumed that not only increase the use efficiency of the terminal through various terminal control functions in the high-speed wireless calling system but also prevent the illegal use of information. It may be implemented in commercially available wireless communication systems such as cellular mobile communication systems, personal mobile communication systems (PCS), and radio frequency systems (TRS), and in this case, it should be apparent that the same as the present embodiment.

FIG. 2 is a flowchart illustrating a method for transmitting a terminal control packet and a method for controlling the terminal according to the present invention, wherein the wireless call exchanger 14 transmits a control message to the wireless call terminal 11 to transmit the control message. ) Shows a procedure of increasing the terminal usage efficiency and preventing illegal use of information through a control message.

Here, the use of the control packet may be defined in various ways. In the present embodiment, there are a control function for battery saving, a control function for scalability of the information field, a control function for preventing illegal use, and the like.

As shown in FIG. 2, the method for controlling a terminal according to the present invention first determines which control is necessary in the radio call exchanger 14, selects a control type (201), and configures a control packet (202). Transfer to calling terminal 11 (203). Subsequently, when the control packet is received from the paging exchange 14 (204), the radio calling terminal 11 analyzes the type of the received control packet (205) to increase the terminal use efficiency and prevent illegal use of information. (206 to 208).

Here, a control packet for battery saving, a control packet for scalability of an information field, and a control packet for preventing illegal use will be described in more detail, which the wireless call exchanger 14 transmits to the wireless call terminal 11.

The structure of the control packet for battery saving and the control packet for scalability of the information field are as follows.

Information address (Capcode) Type of control Parameter

In addition, the structure of the control packet for preventing illegal use is as follows.

Personal Address (Capcode) Type of control Parameter

As such, the control packet is divided into a control type field and a parameter field.

The control type field identifies a type of a control packet and identifies a type of a control packet such as battery control, scalability control, and illegal use prevention. For example, "0001" may be classified into a battery saving control packet, "0010" may be classified into an expandability control packet, and "0011" may be classified into an illegal use prevention control packet.

On the other hand, the parameter field contains the value of the required parameter according to each control type. For example, the battery saving control packet indicates whether the terminal turns the airwave monitoring on or off, and in the case of the scalability control packet, expresses the size and shape of the field to be expanded, and the illegal use prevention packet Store the valid period of the subscriber in the parameter field.

The control packet takes the same form, but the battery saving and scalability control packet is a control packet that must be applied to all terminals in common. Therefore, the control packet is transmitted to an information address or a common address. Send it to your personal address.

This will be described in more detail as follows.

Real-time stock information will only transfer stock information from the opening of the morning stock market until the afternoon closes. Therefore, the radio call terminal 11 does not need to continuously search the airwaves to determine whether the stock information is transmitted at other times such as nighttime or holiday. Therefore, in the present embodiment, real-time stock information is activated only when the stock market is in operation, and deactivated at other times.

However, in the related art, since there is no method for controlling the wireless calling terminal 11 in this case, the transmission is continuously monitored, and the battery consumption is high. However, in the present embodiment, wireless calling is performed through the terminal address monitoring interruption and operation control. The exchange 14 may control the radio call terminal 11 when there is no data to transmit. That is, when the radio call exchanger 14 controls the terminal address monitoring interruption and operation, it constructs a control packet for this (202) and transmits it to the radio call terminal 11 (203). Subsequently, if the terminal address monitoring interruption and operation control packet are received from the radio call exchanger 14 (204), the radio call terminal 11 receiving such a control packet stops monitoring the airwaves for subsequent data reception. (206). At this time, in order to receive a control packet for resuming the monitoring of the airwaves, the part corresponding to one address, such as the common address or information address # 0 of Table 1, must be monitored continuously.

On the other hand, when the paging exchanger 14 wants to change the size of the information packet field or add a new field, it configures a control packet for this (202) and transmits it to the paging terminal 11 (203). The received call 204 analyzes the control packet (205) and stores it in the internal memory, and analyzes the next received information packet in the form of a changed packet (207). This also ensures scalability for future problems.

On the other hand, when the paging exchanger 14 wants to prevent illegal use of the service, it configures a control packet for this (202) and transmits the valid period of service use to the personal address of the paging terminal 11 ( At step 203, the wireless calling terminal 11 receiving the message 204 stores the valid period of the service usage in the memory, and automatically displays the expiration on the screen when the service usage period of the subscriber expires. Therefore, in the conventional embodiment, there is a lot of illegal and unauthorized use of the full-text broadcasted at the information address, which is a common address even when the subscriber is terminated or suspended, whereas in the present embodiment, if the subscriber pays a fee in order to continue receiving the service, it is effective. Periodically inform the control packet of the extended period to prevent illegal use of the service. That is, in the present embodiment, the system periodically accesses the database, and periodically transmits the information that is valid from the current day to the specific date to the subscribers in the database periodically for each person to prevent unauthorized reception of the information.

As described above, in the present invention, in processing a large amount of data that changes in real time using a lot of airwaves, the size of each field may be changed or a new field may be added, which may be the most difficult problem in packet-type communication. In this case, extensibility is ensured by notifying the terminal to the terminal through a control message. In addition, by introducing the advantages of packet communication to the terminal control it is possible to increase the battery efficiency of the terminal and to prevent illegal use of the service.

In the present embodiment, it is assumed that not only increase the use efficiency of the terminal through various terminal control functions in the high-speed wireless calling system, but also prevent the illegal use of information. Implemented in a commercially available wireless communication system such as a personal mobile communication system (PCS), a radio frequency system (TRS), or the like, may be configured to achieve the same effect as in the present embodiment, and in this case, it should be regarded as the same as the present embodiment. Ham is self-evident.

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 guarantees scalability when changing and adding packet fields through various terminal control functions, and increases the use efficiency of the terminal and prevents illegal use of information.
