The Internet Standards Development Organization (IETF) is an Internet standard development organization designed to replace the H.323 standard technology adopted by most commercial Internet telephony services. Engineering Task Force).

SIP is an application layer call signaling protocol that provides multimedia session establishment, session information exchange, and termination functions, and is an essential technology for developing various next generation Internet applications such as Internet telephony and multimedia messaging. In addition, SIP technology has become the core standard technology of instant messenger and presence service that is emerging as the next generation killer application after the web as well as Internet phone, and is adopted as call control protocol in 3rd generation mobile communication service. R & D and standardization of related technologies and the development of SIP-based equipment and services are being competitively pursued.

As the number of Internet users increase, web (WWW) applications based on HTML (HyperText Markup Language) have been developed to enable various Internet businesses and cyber cultures to be created in a cyber space. In particular, in order to implement a community on the Internet, various instant messenger services and presence services have been developed and provided.

The presence service refers to a service that provides a user with presence information such as checking a user's location information, checking a user's communication status, that is, checking a user's online or offline status, and checking a media type.

Recently, an instant messenger, which is used as an online communication means between Internet users, is a type of service that uses presence information as a service for sending a message to a user who is online by using presence information.

These instant messenger and presence services start with simple presence services such as online and offline services of users, and are now extended to services that deliver various types of presence information. It extends to services that combine a variety of non-text voice and video services, chat and conferences.

The current instant messenger service displays the list of users registered as friends and their current status in various icons or texts, checking on / off status, name or screen name, avatar, psychological status, current status, access status, etc. This can be referred to as a form of service using the presence information. Here, the mental state includes various states such as joy, sadness, anger, crying, and the like.

Conventionally, the instant messenger service provided by the wired Internet system was a fixed service provided only between personal computers. However, with the development of terminal technology, data transmission technology, and wireless communication network technology, instant messenger service between mobile communication terminals or between mobile communication terminals and personal computers is also possible. A mobility service that can provide a messenger service has become possible.
