- Infrared communication technology

Infrared (IR) communication technology has been used since the late 1970s as a technology for wirelessly operating home appliances such as TVs. Over time, advances in communication protocols have also led to the development of IC solutions for OEM remote controls, universal remote controls, and computer-based hardware. However, no specific solutions for mobile devices have been developed, and IR communication technology has not been applied to the first smartphone, iPhone and most of the smart phones that have appeared since then. It is made to be possible.

Infrared data communication has advantages of low cost, low power consumption, strong electromagnetic interference, and efficient and reliable data transmission. Generally, the remote control has a unique key code for each button, and the code is divided into lead code + custom code + data code. The lead code indicates that the remote control transmission is started, and the custom code is used for eliminating mutual interference by specifying differently according to the manufacturer, and the data code is a code determined by the key.

- Push Alarm Service

The smartphone push notification service is defined as a technology that informs users when a smartphone application (application) receives information from the server in real time (Korea Telecommunication Technology Association, 2011) When a specific message is delivered to the user device, the user automatically receives the notification regardless of his or her will.

Typical services providing such push messages include GCM (Google Cloud Messaging) and FCM (Firebase Cloud Messaging). In the present invention, the proposed system is implemented using FCM.
