Abstract: The present invention relates to an apparatus and method for providing and controlling multimedia group communication service based on a mesh network. The apparatus for providing a group communication service includes a group communication management module, and an audio and video management module. The group communication management module controls and manages group communication between a plurality of user terminals connected to an internal network independent of an external network. The audio and video management module receives audio and video data for group communication from the microphone and camera of each of the user terminals and manages the audio and video data. The group communication management module includes a packet management unit configured to generate packets that are used to control the group communication, a terminal search unit, and a group communication control unit.
