The present invention relates to a method for receiving general information of a multifunction wireless paging receiver having a battery saver and allowing general information to be received using a predetermined address.

SUMMARY OF THE INVENTION An object of the present invention is to provide a general information receiving method of a multi-function wireless calling receiver which can receive not only a general telephone message but also a predetermined information message without using a special operation while using a service method of a known wireless calling receiver as it is. It is.

In general, a radio call receiver includes a predetermined address, and analyzes the received data and receives message data when its address is checked and notifies the user through a display unit.

The present invention achieves the purpose of the pager and at the same time receives an information message so that the user can receive useful information as a pager of the present invention.

At this time, the information message is information data that changes with time, and examples thereof include exchange rates and stock information. Such information data is provided by the bank information system and the securities information system.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram of a radio call receiver to which the present invention is applied. The radio call receiver includes an antenna 100 for capturing modulated radio frequency data, and a receiver 110 for receiving demodulated signals from the antenna and demodulating them to a logic level. And a decoder unit 130 for receiving and processing logic level data from the receiving unit, and a code memory 190 having its own address data embedded therein and read by the decoder unit 130.

In addition, when the address data in the code memory and the address signal output from the reception unit 110 are compared with the decoder unit 130 and determined to be appropriate call data, the decoder unit 130 displays the received telephone number message on the LCD 120. Display, and store in the MEMORY (memory in the MPU because the 4-bit single chip microcomputer is used in the present invention) in the decoder 130, the alarm in the decoder unit 130 through the external drive unit 140 in accordance with the received state Driving the 170 or driving the vibrator 180, in addition to driving the call indicator 150 in synchronization with the cycle of the alarm sound.

It also has a backlight lamp 160 for backlighting the LCD.

In addition, the outside of the decoder unit 130 has two switch units 230 and 240, one of which is a mode switch 230 for mode conversion and the other is a display switch for reading stored data ( 240).

In the radio call receiver, the "mode" is generally divided into a memory mode and a normal mode. In the memory mode, the alarm does not occur, the vibrator operates, and the alarm occurs in the normal mode.

Since the present invention uses the service system of the existing wireless call receiver as it is, the call method of the wireless pager is not mentioned separately.

The main feature of the wireless paging receiver according to the present invention is that unlike the conventional paging, it has two or more addresses in the code memory 190, one of which is an address for general radio calling, and the other for information calling. This is an address, and the address for the information call has a plurality of information codes for various information calls.

In addition, the information code is to store the type of information for receiving the service, for example, may be composed of five-digit decimal data, may have a plurality of information codes.

In the present invention, a radio call receiver having three addresses and having a maximum of 12 information codes will be described as an example.

Two of the three addresses are for general calls and the other is for information calls.

The basic feature of the method of the present invention is that when the power of the pager is turned on, the decoder unit 130 reads three address data and twelve information codes in the code memory 190 and stores them in the memory in the MPU.

Subsequently, when the data received from the receiver 110 is checked and the same addresses as the three addresses are checked, the decoder 130 receives the message data according to the addresses, and after the reception of the message data is completed, the decoder 130 If the received address is a general call address (two out of three), the normal call flow is performed. If the address is an information call address, the first five digits of the received message (data for checking the type of information) If two information codes are compared and matched, the received data is stored in a specific location of the memory in the microcomputer 132, and no operation is performed according to the reception of an alarm or a vibrator.

If the received message does not match 12 information codes, it is not saved and just discarded.

Therefore, even if information data is received, there is no alarm or vibration.

Hereinafter, the method of the present invention will be described in detail with reference to FIGS. 2 and 3.

As described above, the radio call receiver of the present invention has three addresses and twelve information codes, three addresses are A, B and C, respectively, and the twelve information codes INF1, INF2,... … , INF12.

The memory 1M, M2, M3,... Mn, the memory for storing information messages is represented by IM1, IN2,... It is set as IM12.

Modes available as a normal pager are silent mode and normal mode, which are changed according to the input of the mode switch.Silent mode means a mode that does not generate an alarm sound and emits an alarm such as a vibrator. This mode is to generate sound.

In the present invention, since the information mode is included in addition to the two modes, the mode switches to the silent mode, the normal mode, and the information mode, respectively. In particular, in the information mode, no alarm or vibrator is driven and only the contents of the information memory can be read.

In the information mode, when a general message is received, the alarm mode is automatically changed from the information mode to another mode (silent mode or normal mode).

2, a step (30) of checking received data to check whether its address is received; Storing 32 a state of received address, namely, address A, B, or C, in the memory RWOK1 in the MPU when its own address is received; Receiving (33) a message; There is a process (34) of checking whether message reception is completed, and if the message reception is not completed, the process of receiving the message of step (33) is continued, and if the message reception is completed, checking whether the received address is an information call address. If it is entered in (35), and the call is not made by the address C for information call, the process goes to (36) to check the K counter which counts the number of received messages.

At this time, the K counter increases from 0 to one for each message storage, and increases to the maximum number of storage. In other words, if the k counter is 4, the number of stored general messages is 4, and if it is 20, the maximum number of stored messages is 20.

The process 36 checks whether the number of currently stored messages is the maximum value, and if the maximum value is reached, enters the process 37 of increasing the message location pointer h. If not, the process increases the k counter and increases the contents of the increased k counter to the h pointer. Enter the process of saving 39. Here, the h pointer can be from 0 to 20 at a minimum, indicating the memory in which the received message will be stored.

In step 37, the pointer h is incremented by one. In step 38, it is checked whether the increased pointer value does not exceed the maximum value of 20, that is, the maximum number of stored messages. Set 1 and go to step (41).

In the process 41, the received message is stored in the message Mh corresponding to the h pointer calculated in the previous process (meaning Mh corresponding to the h pointer). Then, the process 41 is performed. Enter the process (42) and check if the current mode is the information mode. If the mode is the information mode, the process automatically changes the mode to another mode (here, the silent mode), and enters the process (44). In step 44, the current mode is checked in silent mode to operate the vibrator in step 46 in the silent mode, and generate an alarm in step 45 in the normal mode. In step 47, the received message is displayed on the LCD.

On the other hand, if the received address is the information call address C as a result of performing step 35, the process proceeds to step 49 to store data of a specific portion of the received message (first five-digit data) in the memory MXX in the MPU. Then, the process enters the process 50, where the process 50 checks whether the contents of the MXX are the same as the information code 1, that is, the contents of the IMF1, and if it is the same, the remaining information data except the data of the specific part of the received message. Is stored in the information memory IM1.

However, if the contents of the MXX in the process 50 is not the information code 1, the process enters the process (52), and the process from (52) to (73) is the same as the process (50) (51).

If the data does not match (step 72), that is, it does not match the information code of its own, it is returned without storing the received message.

3 illustrates a method of reading a message according to a mode change in the present invention, in which a mode change occurs according to an input of a mode switch 230, and a stored message is displayed on the LCD according to the input of the display switch 240. do.

In Figure 3a, the process of checking whether there is an input of the mode switch (80); If the mode switch is input, in step 81, it is checked whether the previous mode is silent. If it is silent, the mode is changed to normal mode and returned in step 82.

However, if it is not the silent mode, it checks whether it is the normal mode in step (83), and if it is the normal mode, it switches to the information mode in step (84), but if it is not the normal mode in step (83), the current mode is information. Since the mode is the same, proceed to (85) to switch to silent mode and return.

As a result of the process 80, if there is no input of the mode switch, the process goes to step 87 to check whether there is an input of the display switch. In the process 87, it is checked whether the display switch is pressed (the display switch is pressed). If the input is HIGH, if it is changed to HIGH, proceed to (89). If not, proceed to (88) to check whether the input is changed to LOW. Check

That is, it is checked if the display switch is released, and if the display switch is changed to the released state, the process returns to step 105 in FIG.

In the process (89), if the display switch is pressed to check whether the current alarm or vibrator is in operation (90) to perform the operation of stopping the alarm or vibrator and return, if the alarm or vibrator is operated If not, proceed to (92) to check what the current mode is.

As a result, if the current mode is the information mode, the process proceeds to (100). If the current mode is not the information mode, the process proceeds to (93) and checks whether there is a general call message received. Indicates that no message was received at and returns.

However, if there is a message received in step 95, the memory indication pointer j is increased in step 95, and the process proceeds to step 96. In step 96, the memory location to be displayed is the total number of received messages. If it is greater than k counters, go to step (98) by entering the initial value 0 into the j pointer. If the j pointer is not larger than k counters, go to step (98).

In step 98, the j pointer value calculated in the previous step is displayed on the LCD to teach and return the memory location to the user.

If it is determined in step 92 that the information mode is selected, the process proceeds to step 100 to increase the i pointer indicating the position of the information code to be displayed at present, and then proceeds to step 101, where the iNavier of the i pointer is the maximum information code. Check if the number exceeded 12.

As a result, when the number exceeds 12, the i pointer is initialized to 1 to indicate the first information code in step 102, and then the process goes to step 103. j Displays the information code indicated by the pointer on the LCD so that the user knows the type of information and returns.

When the input of the display switch is released in the process 88, the process proceeds to step 105b of FIG. 3b to check whether the alarm or the vibrator is in operation. Returns.

However, if the alarm or vibrator is not active, the mode is checked in step 108 if the mode is information mode. If the mode is not in information mode, it checks whether there is a general call message received in step 109. Return if none.

If there is a message received as a result of performing the process 109, the contents of the memory Mj corresponding to the memory pointer j calculated in (95), (96) and (97) of FIG. 3A are displayed on the LCD. After the process 111 is performed, the process returns.

If it is determined in step 108 that the information mode is determined, step 113 is entered. In step 1130, the information memory corresponding to the i pointer calculated in steps 100, 101, and 102 of FIG. Check the contents of IMi), and then proceed to (114) and if there is information data stored in the IMi memory, go to the process (115) to display and return the information data of IMi on the LCD. ) Process to return no data received on the LCD.

As described above, according to the present invention, the service environment of the general pager can receive not only general call messages, but also information data, that is, fluctuation data related to securities and exchange rates. In addition to the silent and normal modes, the call receiver can read the information data by pressing the display switch when it is in the information mode.If the general call message is received while the information mode is in use, the call receiver automatically switches to another mode. Can be converted.

In addition, the memory for storing the information message and the memory for storing the general call message are separately stored.In order to receive the information message, it stores several information codes indicating the type of information. Check if it matches the information code that it keeps and if it is the same, it saves the remaining message received in the information memory corresponding to the same information code, and does not generate any alarm in response to receiving the information message. It can be used.
