The present invention relates to a method and system for providing an instant messaging service in a mobile communication system. More specifically, when a subscriber sends and receives a short message in a mobile communication system and presses an instant messaging service button provided in the mobile communication terminal as necessary, the subscriber's mobile communication terminal communicates with another subscriber's mobile communication terminal via a relay gateway server. The present invention relates to a method and system for providing an instant messaging service in a mobile communication system that connects using an IP protocol and transmits an instant message created from a subscriber to a mobile communication terminal of another subscriber.

 Instant Messenger refers to various softwares that enable interactive communication between communication terminals in real time or near real time through a computer network or the like. The distinction between instant messenger and e-mail is that instant messenger is not only able to perform real-time communication interactively, but also to log in when an instant messenger is logged in by establishing an acquaintance relationship between contacts. You can notify them or know their current status. What's more, recent instant messengers add features like file transfer, chat room, file sharing, voice and video chat, Internet private broadcast, avatar / character decorating, short message sending, stock retrieval, email, network games, and more. It is rapidly changing to various communication platforms.

In order to use instant messenger services currently provided by MSN, ICQ, Daum, and Nate, users download and install an instant messenger program to their computers. When a user executes an instant messenger program installed on a computer, the user is automatically connected to a corresponding instant messenger server or system to enable instant messaging with acquaintances who use the same instant messenger program.

Meanwhile, with the rapid development of electronic engineering and communication engineering, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data communication technology, people can use not only voice calls but also Internet access, video communication and video message transmission using mobile communication terminals. Furthermore, people have been provided with a wireless instant messenger service using a mobile communication terminal.

Meanwhile, in the conventional method of delivering a message by a wireless instant messenger, a mobile communication terminal of a calling subscriber transmits a message to a message center, the message center stores the received message in a database of the message center, and sends a confirmation notification to the calling subscriber. do.

In addition, the message center determines whether it is a wireless instant messenger member through the called number included in the message, and if it is determined that it is not a wireless instant messenger member, transmits a subscription message to the mobile communication terminal of the called subscriber, and determines that it is a wireless instant messenger member. In this case, the current state of the wireless instant messenger of the called party corresponding to the called number is retrieved.

Here, the message center transmits a message to the mobile subscriber station of the called subscriber if the current state of the wireless instant messenger of the called subscriber is not receivable, and if the current state of the wireless instant messenger of the called subscriber is receivable, Send a message to your computer.

However, the conventional wireless instant messenger service has more overhead than a message transmitted and received, causing a burden on the mobile communication network, delayed message transmission due to network delay, and the like.
