스마트폰 착신번호 자동송신을 위한 애플리케이션 구현

Abstract

This thesis is intended to explain Bluetooth-based incoming numbers automatic transmission system by implementing an application, which automatically extracts the number of an incoming call as a smart phone, with Android OS, receives a call. It then automatically transmits the incoming number by means of the built-in Bluetooth and relay station, which converts Bluetooth signals into ZigBee signals. This helps to solve the weak points of Bluetooth and makes it possible to communicate with up to 255 devices and expand its possible communication range. The application in this work was developed using Android development tools in order for Android smart phones to extract the incoming number from incoming information and automatically transmit the number. After the application is executed it is in the ready state until any incoming call occurs. When any incoming information is receieved, the application extracts its incoming number from the information and then automatically transmits the number to a relay station through Bluetooth communication. To solve the weak points of Bluetooth, such as a short communication distance, the limited number of communication devices (up to seven), the sensitivity to surroundings, the relay station converts the Bluetooth signals to ZigBee signals. It is therefore possible to communicate with up to 255 devices and expand its communication range because the converted signals are less sensitive to surroundings. As described earlier, this research implemented and verified Bluetooth-based incoming number automatic transmission system that consists of an application to automatically handle the incoming calls received by smart phones, and a relay station to convert Bluetooth signals into ZigBee signals.
