Description

ZIGBEE function utilization pager {PAGER SYSTEM WITH ZIGBEE FUNCTION}

The present invention is designed to make it easy for the user to recognize that the call is coming from the mobile phone while the mobile phone is placed in a handbag or a bag, which is inconvenient to carry, so that the user can use the ZIGBEE-IEEE 802.15.4 wireless cordless pager. When a phone call is worn on a mobile phone, the mobile phone recognizes it first and sends information about it to a small pager, and the small pager rings it by vibrating light. It's about a pager with the ZIGBEE specification to easily identify that it's coming.

On the other hand, there are various wireless standards that can be applied as a wireless pager. The existing Bluetooth (BLUETOOTH) standard or the wireless LAN (IEEE 802.14) standard. Zigbee (ZIGBEE, IEEE 802.15.4), FM (Frequency Modulation) method.

First of all, the Bluetooth specification is too complex and versatile. In addition to data processing, audio can be processed and a 32-bit processor is used to process protocols (standards) including rules for processing various functions. Wireless LANs also have the disadvantage that they need to be replaced frequently because of the complexity and power consumption of Bluetooth. The FM method has a disadvantage in that the noise effect to other devices is large and the antenna is large. Compared with these disadvantages, the ZIGBEE standard has the following advantages.

1. The protocol (standard) is very simple, so the miniaturization of hardware is very advantageous.

2. Hardware is relatively simple, which can reduce power consumption and extend battery life.

3. The protocol (standard) is not complicated and hardware is simple, so it can be implemented inexpensively.

The ZIGBEE standard has a coordinator (master role) and a device (slave role) to communicate with each other. The frequency used is 900MHZ band or 2.4GHZ band and data can be transmitted in both directions. The block structure of the coordinator and the device is the same, and communication between the coordinator acting as a master and the device acting as a slave is possible by registering a unique number of a device corresponding to the slave in advance. A small antenna, a modulation / demodulation unit for detecting (transmitting data) a portion of a signal received from the antenna, and a Mac-MAC for processing the detected data in accordance with a protocol (composing data according to a protocol). (Medium Access Control)-consists of a processor and a microprocessor for controlling them. Each wireless standard has a modulation / demodulation section and a Mac-MAC (Medium Access Control) -processing block, but the ZIGBEE standard has a simple protocol (standard) that allows for relatively simple processing of these blocks and a high performance microprocessor. It can be implemented as an 8-bit processor instead of the 32-bit processor.

In general, a cell phone is a personal necessity for almost everyone, but even a little heavy enough to enter a weight race is often a burden on the user. In winter, it is convenient to carry a cell phone because of its thick coat, but in summer, it is inconvenient to carry it in a pocket, so it is often carried in a bag or a handbag. However, if you carry it in your bag or handbag, you may not be able to hear your phone call because you do not hear the sound, and in many cases, you may miss the ringing of your mobile phone, especially when you are taking a bus or riding the subway. .

Therefore, the present invention has been devised to solve the above-mentioned problems in the related art, and when the phone comes to the user's mobile phone, it recognizes it and the structure is very simple. The purpose of the present invention is to create a device that makes it easy for a mobile phone user to know that a call has been received by receiving information about a call while wearing it on a user's waist or making a necklace.

Critical block that mainly handles data corresponding to protocol (standard)

The present invention for achieving the above object is formed a block of the coordinator (master role) function to which the ZIGBEE standard is applied in the mobile phone, and separately constitutes a system as a pager that serves as a device (slave role). . In addition, it is a structure for acquiring and processing radio call information, and a block for processing protocol (standard) and a circuit for enabling selection by a selector switch (SW) among vibration or other ringing sound in a pager worn by a user. It features.

FIG. 1 is a mobile phone block diagram including a ZIGBEE coordinator block 13 serving as a master in the user's mobile phone 11. The pager 12 with ZIGBEE functions as a device (slave). When the phone comes to the mobile phone 11 is first received by the antenna 16 and then demodulated. The demodulated data is signaled to the notification device 14 to ring or vibrate after processing in the processor 15. At this time, a circuit is configured so that the coordinator 13 acquires this signal at the same time, so that the coordinator 13 also operates almost simultaneously. As a result, a bell rings in the mobile phone 11, but the coordinator 13 also operates. At this time, the signal transmitted from the coordinator 13 is a pager 12 which is a device device (slave role) of ZIGBEE in a short distance. ) Is transmitted to the pager 12 to vibrate. Again, the order of signals is as follows.

A processor 15 for processing the received signal to process the incoming call;

A notification device 14 for receiving a signal from the processor 15 and selecting a bell or vibration;

A coordinator 13 which receives a signal identical to a signal input from the processor 15 to the notification device 14 and generates a signal for a Zigbee pager;

And a device apparatus conforming to the Zigbee standard, comprising an antenna for wirelessly transmitting the output signal of the coordinator (13).

2 is a circuit block diagram of a pager for applying the ZIGBEE standard. The antenna 26 is very small enough to be implemented on a circuit board without using a separate component. Since the coordinator periodically sends information to the device and checks the unique number of the device (slave role), the information delivered directly to the pager, which is the device, is analyzed by the MAC processor 29 and there is no problem. The microprocessor 22 passes the information to the selector 23. At this time, the user selects whether to vibrate or ring according to the expression method defined in the selection switch (SW) 21 in advance in the selector 23. When the mobile phone user knows that the call comes from a pager, which is a device, the user presses a call button on the mobile phone 11 so that the user starts talking on the phone. At this time, when a mobile phone user receives a call, the coordinator (master) transmits the information from the coordinator (master) to the pager, which is a device (slave), so that the pager continuously vibrates or stops ringing.

Reorganize according to the signal flow

An antenna 26 for receiving the transmission signal of the Zigbee coordinator 13;

A modulator / demodulator 28 for demodulating a signal received from the antenna 26;

Receives an output signal from the modulator / demodulator 28 to process protocol data

MAC-Medium Access Control (MAC) -processing unit 29;

A microprocessor (22) for controlling the modulator / demodulator (28) and the ZigBee MAC (29) processor;

And a selector 23 that receives a signal from the microprocessor 22 and performs a notification operation. The selector 23 includes a circuit for selecting any one of a vibration generator and a ringer generator.

Although it is inconvenient to carry a mobile phone in a bag or a handbag, it is often carried in a bag or a handbag. If you're riding the subway, you'll miss the ringing of your cell phone. Therefore, wearing a pager with a lightweight ZIGBEE standard in the form of a waist or a necklace of a mobile phone user is very convenient because the mobile phone user is notified of vibrations so as to easily recognize that the mobile phone is called through the pager.
