Magnetic Address Writing Method in Wireless Call Receiver with Wireless Auxiliary Pager

The present invention relates to a method of receiving a call signal in a wireless auxiliary pager of a wireless call receiver, and more particularly, to a magnetic address in a wireless call receiver having a wireless auxiliary pager that receives its own call signal separately from a call signal transmitted from another wireless call receiver. It is about a light method.

Wireless call receivers are so popular that almost everyone carries them. As radio call receivers are used by many people, research continues to add functions to meet user's needs. In response to this, a wireless call receiver is a two-way wireless call receiver capable of bidirectional communication and a text call receiver capable of receiving a text service from a wireless call system and displaying it on a liquid crystal display (LCD). Was done.

As the wireless call receiver emerges as described above, the size of the wireless call receiver has resulted in a relatively large size compared with the conventional general wireless call receiver. As a result of this, the user may wear the wireless page receiver close to the human body (e.g., neck, waist, etc.) and carry (e.g., pocket) and carry it in a bag. In many cases, it is impossible to respond to a received message.

For this reason, a compact and lightweight wireless auxiliary pager, which generates an alarm separately from the wireless call receiver, has appeared. The wireless auxiliary pager receives an intermediate frequency call signal from a short range wireless call receiver and generates an alarm, so that it is necessary to distinguish it from the call signal of another wireless call receiver.

Accordingly, an object of the present invention is to provide a method of setting a magnetic address in a wireless call receiver having a wireless auxiliary pager that writes a magnetic address to its own wireless auxiliary pager and generates an alarm only for the call signal transmitted from the wireless pager. .

In order to achieve the object of the present invention, the present invention relates to a magnetic address writing method in a wireless call receiver having a wireless auxiliary pager, wherein the wireless call receiver comprises data consisting of a predetermined magnetic address write code and a synchronization code including a magnetic address. A first step of modulating a stream into a call signal and transmitting the stream to a call receiver; receiving the call signal from the call receiver in a state where a register of a call receiver is initialized, and demodulating the call signal into a data stream; And a second process of detecting and synchronizing a synchronization code from the data stream, detecting a magnetic address write code, detecting a magnetic address included in the magnetic address write code, and writing the result to a register.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a wireless call receiver to which the present invention is applied.

Hereinafter, referring to FIG. 1, the radio frequency unit (hereinafter referred to as an “RF unit”) 10 may amplify a weak radio signal received through the first antenna ANT1 and detect only a desired signal. Filtering is carried out for the purpose of mixing, and mixed with the local oscillation frequency to convert to the signal of the intermediate frequency and output. The demodulator 20 demodulates the signal from the intermediate frequency into a post office code standard advisory group (POCSAG) which is an original signal and outputs the demodulated code. The decoder 30 restores the original data by filtering the decoded code, and performs a battery saving operation by detecting an error and demodulating a synchronization signal. The first memory 50 includes a ROM for storing a predetermined operating program, a RAM for temporarily storing data generated during the operation, and an electrically programmable EEPROM. The intermediate frequency unit 60 (hereinafter referred to as an "IF unit") 60 receives a predetermined control, receives a predetermined data stream, modulates it into a call signal of an intermediate frequency, and transmits it through the second antenna ANT2. The key input unit 42 includes a read key for checking a received message, a mode key for setting a mode, and a selection key for changing and selecting an option value. The display unit 44 displays the received message and a plurality of information by icons. The alarm unit 46 generates alarm sound and vibration when a message is received under predetermined control. The first control unit 40 controls the overall operation. When the message is received, the first control unit 40 generates a data stream in a predetermined format and outputs the data stream to the IF unit 60.

FIG. 2 is a data format diagram of a data stream generated by the first controller 40 of FIG. 1. 2 shows a sync code, which is made up of 16 bits and is a bit string for synchronizing. 2 b shows a call code, which is one codeword, and is configured by using Hamming (15, 11) codes, and additionally, an even parity bit is added thereto. In FIG. 2B, the option R is composed of 2 bits, and is a bit for adjusting the turn-on period of the receiver of the power saving mode. Assuming that the initial receiver turn-on cycle time is 2sec (when the option value is "0"), the receiver turn-on cycle time is the receiver turn-on cycle time, which is the product of the initial receiver turn-on cycle time multiplied by the option value. For example, if the initial receiver turn-on cycle time is 2 sec and option R is 4, the receiver turn-on cycle time is 8 sec. The code type (C) is composed of 3 bits and is a bit for indicating the type of codeword. That is, it is a bit for indicating whether the codeword is a sync code, a call code (eg, 101) or a self address write code (eg, 001). The address ADD is composed of 6 bits, and the cap code is divided by 64 to convert the quotient to binary.

One data stream repeats the synchronization code and the codeword configured as described above for a predetermined time, and typically, the predetermined time is 4 seconds. This is a method for reducing current consumption by periodically turning on / off the receiver at the auxiliary pager, and performs a better power saving function than using a preamble signal used in the wireless page receiver.

Referring to Figure 2 below, the intermediate frequency receiver (hereinafter referred to as "IF receiver") 210 receives the call signal of the intermediate frequency transmitted from the radio call receiver through the third antenna (ANT3), and weak Amplified, filtered and demodulated in the original data stream is output. When the call signal is received, the alarm unit 230 generates alarm sounds and vibrations under predetermined control. The microprocessor 220 receives the data stream and detects the received field strength of the data stream to determine whether the received field strength is greater than a preset reference received field strength. As a result of the determination, if the received electric field strength is greater than the preset reference electric field strength, the microprocessor 220 maintains the power saving signal in an active state for a period of 48 bits. The microprocessor 220 detects and synchronizes a sync code SC from the data stream received during the 48-bit time period. When the microprocessor 220 is synchronized by the sync code SC, the microprocessor 220 detects a codeword continuously inputted to the sync code SC and stores the codeword in the internal memory. In addition, the microprocessor 220 analyzes the stored codeword to perform a corresponding operation according to the code type (C).

The microprocessor 220 includes a second decoder 221, a second memory 225, and a second controller 223. The second decoder 221 receives the data format output from the IF receiver 210 to perform synchronization code detection, detection of electric field strength, and battery saving. The second memory 225 stores a ROM storing a predetermined program, a RAM storing an initial turn on cycle time of a power saving signal, and a magnetic address of the detected codeword. Has a register The second controller 223 stores, reads, and erases data.

4 is a flowchart illustrating a method of configuring magnetic address write code data for setting a magnetic address in a wireless auxiliary pager in a wireless call receiver according to an embodiment of the present invention.

Referring to FIG. 4, first, when a predetermined key is input from the key input unit 42 in step 201, the first controller 10 switches to the magnetic address write mode. In operation 203, the first controller 40 generates a magnetic address, and displays the generated magnetic address on the display unit 44. The magnetic address generation method calculates and generates a unique cap code of the radio page receiver by Modulo64. The modulo 64 sets the value obtained by converting the quotient of the cap code divided by 64 into a binary number as a magnetic address. The magnetic address displayed on the display section 44 is represented by a decimal value. When the magnetic address is displayed on the display unit 44, the first control unit 40 checks whether a command for receiving confirmation from the user whether to correct the displayed magnetic address or to use the displayed magnetic address in steps 204 and 205. do. If a predetermined key is input from the key input unit 42 in step 204 and the use of the displayed magnetic address is selected, the first controller 40 temporarily stores the magnetic address in the RAM in step 207.

However, when a correction command of the magnetic address by a predetermined key input is input in step 205, the first control unit 40 switches to the edit mode in step 206, and a correction bar (for example, _ is displayed on the magnetic address displayed on the display unit 44). ) Is displayed. The correction of the magnetic address is performed by placing the correction bar on a number desired to be corrected by a predetermined key input and inputting a predetermined key until the desired number is displayed. Even during the correction of the magnetic address, the first control unit 40 periodically checks whether the magnetic address confirmation command is input in step 214, and when the magnetic address correction is completed and a confirmation command is input by a predetermined key input, the control unit proceeds to step 207. Go ahead and temporarily store your own address in RAM.

When the magnetic address is stored in the RAM, the first control unit 10 displays a message (eg, do you want to set an option? Yes or No) on the display unit 44 in step 209, and proceeds to step 211. Check that the setting is selected. If the option setting is selected in step 211, the first controller 40 proceeds to step 213. If the option setting is not selected, the first control unit 40 sets the initial option value in step 212. The initial option value is set to "0". In step 211 to step 213, the first controller 40 checks whether an option value is selected. The option value has a value of 0 to 4, and adjusts the turn-on cycle time of the receiver for battery saving according to the option value. If any of the option values is selected in step 213, the first controller 40 temporarily stores the option values in the RAM in step 215. When the option value is stored, the first control unit 40 proceeds to step 217 to form a magnetic address write code based on the magnetic address and the option value stored in the RAM and outputs the magnetic address write code to the IF unit 60 in the form of a data stream. . The IF unit 60 receives the data stream and transmits a call signal, which is a signal of an intermediate frequency, through the antenna ANT2. Then, the first controller 40 configures a call code for testing whether the magnetic address is written to the wireless auxiliary pager by the magnetic address write code transmitted in step 217, and in the same manner as the magnetic address write code transmission. Transmit via the antenna ANT2 via the IF unit 60.

5 is a flowchart illustrating a method of setting a magnetic address from the magnetic address code data of FIG. 4 in a wireless auxiliary pager according to an embodiment of the present invention.

The second decoder 221 of the wireless auxiliary pager is controlled by the second controller 223 to operate the IF receiver 210 by a battery saving operation by an initial option value "0" set in the second memory 235. Turn on. When turned on, the IF receiver 210 demodulates and outputs a signal of an intermediate frequency received through the antenna ANT3 in the form of a data stream.

In operation 301, the second controller 223 determines whether a reset signal is input from the reset input unit 240. When the reset signal is input from the reset input unit 240, the second controller 223 initializes the register in step 302 and proceeds to step 303.

After the reset signal is not input or the register is initialized, the second decoder 221 sets a reference reception field strength level preset in the second memory 235 from the IF receiver 210 in accordance with the receiver turn-on cycle in step 303. Check if a data stream with a higher received field strength level is input. If a data stream having a received field strength higher than the reference received field strength level is input in step 301, the second decoder 221 synchronizes with the sync code SC of the data stream in step 304, and then detects a codeword. do. Then, the codeword is output to the second control unit 223. The second controller 223 receives the codeword from the second decoder 221 and checks the code type C of the codeword in step 305 to determine whether the codeword is a self address write code. If it is determined that the magnetic address write code, the second control unit 223 proceeds to step 306 to detect the magnetic address from the magnetic address write code. When the magnetic address is detected in step 306, the second controller 223 proceeds to step 307 to check whether the register is initialized. If the register check result register is initialized, the second controller 223 proceeds to step 308, stores the detected magnetic address in the register, and then sets the magnetic address authentication function flag of the second memory 235 to set. And switch to standby. When the magnetic address is stored in a register, other magnetic addresses and data cannot be written to the register until a reset signal is input from the reset input unit 240 or power is consumed. When the self address authentication function flag is set to the second control unit 223, the second control unit 223 executes a function of authenticating whether the call is a call to the received codeword (call code).

On the other hand, if it is determined in step 305 that the self address write code does not proceed to step 310 to determine whether the call code. If the determination result is a call code, the second controller 223 proceeds to step 311 and checks whether the self address authentication function flag is set. If the self address authentication function flag is set to 3 in step 311, the second controller 223 proceeds to step 312 to detect the self address from the call code. In operation 313, the second controller 223 compares the detected magnetic address with a magnetic address previously stored in a register to determine whether the same is the same. If the determination result is the same, the second control unit 223 proceeds to step 315 to control the alarm unit 230 to generate an alarm. Otherwise, the second control unit 223 does not generate an alarm.

If the self address authentication function flag is not set to 3 in step 311, but if the self address authentication function flag is not set to 3, the second control unit 223 proceeds to step 315 and enters the call code without authentication of the self address. Raise an alarm for

The call signal including the data stream generated by the pager is transmitted not only at the intermediate frequency but also at the radio frequency, and it is also easy to carry out the wireless auxiliary pager to write the magnetic address by receiving the call signal at the radio frequency. Will be natural.

As described above, the present invention has an advantage in that the wireless auxiliary pager can generate an alarm sound by dividing its own call signal and distinguish the call signal transmitted from another wireless call receiver.

Another advantage of the present invention is that it is possible to extend the life of the battery by adjusting the turn-on period of the receiver by the option value.
