The present invention relates to a simultaneous call notification, missed call number notification and SMS two-way transmission method in a computer using IrDA and Bluetooth, and more particularly, by a communication system of a mobile communication terminal and a PC using IrDA and Bluetooth. When a call is received, the caller ID is displayed by a separate program on the PC, indicating that the call is coming. When a missed call is received, the missed call is displayed on the messenger window. The caller name and phone number are displayed. The present invention relates to a simultaneous call notification, a missed call number notification, and an SMS bidirectional transmission method in a computer using IrDA and Bluetooth capable of bidirectional transmission between mobile terminals.

In general, Bluetooth is named after Herald Bluetooth, the king of Vikings, who unified Denmark and the Netherlands around the 10th century, and is now the global standard for short-range wireless data communications.In Bluetooth 1.0, 2.4GHz, ISM (Industrial Scientific Medical) Provides short range wireless communication even in the presence of obstacles by using radio frequency without limiting the direction of the band, and has a small size (0.5 square inch) and low power consumption (10mW) It provides wireless data communication at a speed of 1Mbps between 10m ~ 100m (in case of high power) between portable devices such as headsets, PDAs, and peripheral devices such as PCs. In addition, 1 Mbps speed (actual effect speed 721K) enables wireless connection of various terminals within a maximum of 10m. Optionally, when the output amplifier is high-powered, the possible distance can be short-range wireless communication up to 100m distance and 2.4 GHz band. It is a very fast frequency hopping spread spectrum technology that changes 79 channels per second by setting 79 channels with a bandwidth of 1 MHz, and transmits and receives radio waves very low (0.3mA in standby state, up to 30mA in data exchange). ). Therefore, it is possible to wirelessly connect to a laptop computer, a portable terminal, a game machine, a digital camera, a printer, an MP3 player, a home network device equipped with a Bluetooth module, and form an ad hoc network to communicate with each other. Provides near field communication service.

The Bluetooth system defines two types of links, synchronous connection-oriented (SCO) and asynchronous connectionless (ACL), to support multimedia applications that mix voice and data. SCO links are usually symmetrical and circuit-switched for voice, and support point-to-point communication.

Bluetooth devices in the communication range between each other may form an ad hoc network to communicate with each other. In principle, each device is an equivalent device with the same hardware capabilities. Unlike cellular systems, Bluetooth systems do not distinguish between terminals and base stations. Two or more Bluetooth devices sharing one channel form one piconet, and one of the devices participating in the communication to control traffic on the channel becomes the master of the piconet. Any device can be the master, but the device that set the piconet is considered to be the master and the other devices are slaves. If the slave device wants to take over the master role, it can switch roles. Nevertheless, there is only one master in the piconet.

All devices in the piconet use the master device's address and clock to follow the frequency hopping channel. Every device also has its own free-running clock. When the connection is established, a clock offset is added to synchronize the slave and master clocks. Without adjusting its own clock, only the offset is valid during the connection. The master device controls all traffic on the channel and reserves slots to allocate capacity for the SCO link. Polling is used for ACL links. First, it can transmit to the slave-to-master slot only when it is specified by the MAC address in the master-to-slave slot. Master-to-slave packets select a slave. In other words, traffic packets sent to one slave automatically select the slave. If there is no information to send to the slave, the master can use a packet to select the slave. This packet consists only of an access code and a header. This central polling scheme can eliminate collisions between slave transmissions.

In addition, IrDA (Infrared Data Association) is a technology that transmits data in the infrared without a cable, and IrDA (Infrared Communication) communicates using infrared (Infrared) as its name, and v1.0 standard SIR (SerialInfraRed) Fast InfraRed (FIR) is a v1.1 specification. IrDA basically operates only within 1m and has a directivity structure that can transmit and receive data only in specific directions. SIR, a v1.0 specification, operates at speeds up to 115.2 Kbps, and FIR, a v1.1 specification, operates at 4-16 Mbps. IrDA is very easy and simple to use because it connects to the remote control and the TV just by facing the IrDA ports of the two devices.

Unlike the existing LAN, the Bluetooth and IrDA technologies are all focused on personal networks. In other words, it is a technology that connects devices that are in or near the public network, rather than being connected to a public network such as the Internet.

Bluetooth and IrDA Features     Method name                Bluetooth                IrDA  Data rate   1 Mbps (actually 721 kbps)  4 Mbps (16 Mbps with advanced IR)  Frequency band   2.402 to 2.480 GHz band  Infrared   Modulation method  Frequency hopping spread spectrum technology (hopping frequency up to 1,600 times per second)  4-step PPM / 16-step PPM (primary modulation only)   Voice transmission   Yes (encoded by CSV or logarithmic PCM)            impossible   Max transmission distance         10 m (1 mW, 0 dBm) 100 m (100 mW, +20 dBm)            3.8 m  Power consumption or current      30 mA when transmitting data 0.3 mA when waiting            MA   Security      Standard (Authentication, Encryption)            none

Referring to Table 1, the biggest difference between the two technologies, Bluetooth and IrDA, is mainly based on 1: 1 (point-to-point) communication between devices using Infrared for IrDA. It is used for voice transmission, and Bluetooth uses a 2.4 GHz band, so that 1: N (point-to-multipoint) devices can be connected to each other or nearby devices to form a personal network. Voice transmission is possible.

Mobile users who see a lot of their daily work on their desk PCs often place their phones in their pockets or other invisible places, and often do not hear both vibrations and melodies.
