BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paging receiver (hereinafter referred to as a receiver). More particularly, the present invention relates to a circuit and a control method for generating a vibration in which a unique sound or pattern is different according to a caller's unique number.

Typically, paging is used when you want to call someone whose material is unknown. Looking at the operation process, first, the caller dials the special number and the called party's unique number for performing the paging function on the extension telephone. In response to the dialing, the paging station outputs a unique radio frequency (hereinafter referred to as RF) signal to the called party. At this time, the receiver of the called party receives the RF signal to generate an alert, which is a call signal (hereinafter, referred to as a specific sound or vibration). This allows the called party to recognize the situation in which it is calling and take the next action.

By the way, the conventional alarm only consists of the same pattern, it merely passes the call signal. In other words, the called party must go through the procedure of looking at the receiver to identify the caller or the cause of the call, confirming the caller displayed on the display window, and calling the caller to confirm the contents. Therefore, if the call cannot be made immediately, the response to the caller may be delayed.

Accordingly, an object of the present invention is to provide a circuit and a control method for generating a vibration in which a unique sound or pattern is different according to the caller's unique number.

According to an aspect of the present invention, there is provided a paging receiver comprising: means for differential demodulation and waveform shaping of a radio signal received through an antenna, a self-unique address of a paging receiver, and a plurality of alarm related information; When the data of the magnetic frame is selected from the flash memory and the waveform-shaped signal, and the address codeword included in the data of the selected magnetic frame is compared with the self-unique address of the flash memory by using the address bits, the same address is determined. Means for determining self-calling, display means for displaying a message codeword under the control of the control means, and accessing alarm related information of the flash memory according to the caller's unique number to generate a corresponding alarm sound generation control signal. Means for generating and in response to said alarm sound generation control signal The alarm and the means for generating the warning sound, characterized by a composed from the outside to the interface means for inputting the alarm information in the flash memory.

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 addition, in the following description, many specific details such as components, voltages, etc. of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It will be obvious to those of ordinary skill in the art. 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.

First, the operation of the overall paging receiver will be described with reference to FIG. 1. FIG.

The FSK modulated RF signal received through the antenna 10 is applied to the RF receiver 11, and the RF receiver 11 generates a differential demodulation signal by performing a quadrature detection on the received RF signal. . Here, it is assumed that the RF signal is data in the form of a POCSAG (Post Office Code Standardization Advisory Group) code as shown in FIG. The waveform shaping unit 12 receiving the differential demodulation signal of the RF receiver 11 filters and amplifies the demodulated signal, and then waveform-shapes the digital level to a microprocessor 13. At this time, in order to save power, the microprocessor 13 uses a power saving signal, which is a signal for controlling the supply of the first power V + of the RF receiver 11 and the waveform shaping unit 12 according to the state of periodic or received data. power on "on" or "off". In addition, the microprocessor 13 may store an address in the flash memory 15 in an internal RAM when the initial power is “on”, and receive the bread code through the waveform shaping unit 12. Each time, an address codeword (32 bits) is also stored in the RAM, and these two addresses are read by 4 bits and compared by the accumulator (ALU) to determine whether self-call data is present. In other words, the flash memory 15 has a unique address of the corresponding paging receiver (dual address), and the microprocessor 13 has data received in eight frames per batch in the code shown in FIG. Select the data of the specified magnetic frame, and compare the 32-bit address codeword among the contents of the received data of the magnetic frame with the self-specific address of the flash memory 15 and the address included in the received data by using the address bits to the same address. Upon determination, the microprocessor 13 displays the message codeword on the display unit 14 and simultaneously drives an alert driver 16 to generate an alarm sound through the speaker 17. At this time, since the message codeword becomes the caller's telephone number, the display unit 14 displays the caller's telephone number. In addition, the DC-DC converter 18 converts the power of the paging receiver into the first power supply V + generated by the power supply unit 19 and the first supply power V + and converts the power into a relative power of a predetermined total power. There is a second supply voltage V +. That is, when the total voltage is 3V, when the first supply power V + generated by the power supply unit 19 is + 1.6V, the second supply power V + through the DC-DC converter 18 is -1.4V. If the first supply power V + is +1.3 V, the DC-DC converter 18 outputs the second supply power V + at −1.7 V while consuming more current than that described above. At this time, the paging receiver simultaneously supplies a second supply power V + through the first supply power V + through the power supply 19 to the RF receiver 11 and the alarm driver 16 as shown in FIG. Supply.

Some of the configurations described above are described in detail in the 'paging receiver', which was previously filed by Applicant and published as Publication No. 91-3050. However, by using a flash memory (programmable) instead of the flash memory used to configure the 'paging receiver', the user can input unique information from the computer 20 through the computer interface unit 21. There is a difference in that.

Here, assuming that a unique alert has already been provided in the flash memory by the receiver manufacturer, the present invention codes according to the flowchart of FIG.

The terminology used to describe each step of FIG. 2 is defined as follows.

1. Initial screen: Normal display that the user sees on the display

2. Number of Alarms Provided (Nt): Number of unique alarms provided by receiver manufacturer

(Limited by the amount of flash memory.)

3. Number of used alarms (Nu): Number of unique alarms already assigned and input by Nt users

4. Number of usable alarms (Nr): Number of remaining alarms that can be assigned by the user among Nt

(Nr = Nt-Nu)

5. Alarm code: Custom code part of the calling code promised between the caller and the called party

6. Alarm number: serial number of unique alarm defined by the manufacturer of the receiver

7. default alert: Alert provided when unregistered alert code is received

3 is a flowchart illustrating an operation process in an alarm input mode during a paging reception process according to the present invention. The alarm input mode is a mode for inputting an alarm code promised between the caller and the called party. When the alarm input mode is selected in the initial screen display state (steps 3a and 3b), the available alarm number Nr is displayed on the display unit 14 (step 3c). Then, it is checked whether the available alarm number Nr is 0 (step 3d). At this time, if the available alarm number Nr is not 0, the alarm code is input and then it is checked whether the code is already registered (steps 3e and 3f). If the code is already registered, the alarm code is input again (step 3e). If the code is not already registered, an unregistered alarm number is displayed and an alarm is generated accordingly (step 3g). If the user who saw this indication and alarm selects an alarm number, the number is registered (step 3h). After that, it is checked whether the selected alarm number is registered (step 3i), and if registered, the process returns to the initial screen display step (step 3a). In addition, the display returns to the step of displaying the initial screen (step 3a) even when the available alarm number Nr is zero.

4 is a flowchart illustrating an operation process in an alarm test mode during a paging reception process according to the present invention. The alarm test mode is a mode in which a user checks an alarm pattern provided by a manufacturer. When the alarm test mode is selected in the initial screen display state (steps 4a and 4b), the display unit 14 displays the number of provided alarms Nt (step 4c). When the user who sees this indication enters an alarm number, the microprocessor 13 recognizes this (step 4d) and generates registration information (step 4e). Then, it continues to check whether or not to register by entering the alarm number (step 4f), and proceeds to step (4d) to enter the alarm number again depending on whether or not, or returns to the step of displaying the initial screen (step 4a). Goes.

5 is a flowchart illustrating an operation process in a call reception mode during a paging reception process according to the present invention. The call reception mode is a case where the user is actually called after the alarm input is completed. When the call signal is generated in the initial screen display state (step 5b), the microprocessor 13 recognizes this and extracts the alarm code and compares it with the registration alarm code (steps 5c and 5d). If it is determined that the comparison is already registered, a registration alarm is generated, and if it is not already registered, a basic alarm is generated (steps 5e to 5g). After generation of the registration or basic alarm, the process returns to the step of displaying the initial screen (step 5a).

In this embodiment, since the memory-related circuit to store various tones and the input device for the callee to program the alarm need only be added to the existing paging receiver, the change of hardware is not large. Therefore, it can be applied to existing wired / wireless phones. In addition, when using a flash memory as in this embodiment, it is possible to provide the user with upgraded data through a serial input / output device with the outside, so that a good effect can be obtained in terms of service. Productivity can be dramatically increased by reducing ROM installation and replacement time.

Although a new button may be attached to the alarm for inputting programs and other data necessary to carry out the present invention, additional programming related to the operation of the button will be required if the user wants to use the existing appearance.

The present invention is expected to be widely applicable to receivers equipped with numeric displays as well as receivers equipped with alphanumeric displays or graphis displays.

In conclusion, the present invention as described above, if the frequent caller or the call contents are programmed in a unique alert pattern such as a unique melody or vibration pattern according to the caller's promise, the caller or the caller can check the caller beforehand. Because you can grasp the contents of the call, there is an advantage that can effectively deal with the situation that can not make a call immediately.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.
