The present invention reduces the handover delay time even in a situation where handover is frequently requested, thereby providing mobility of unstructured data (sensor, GPS, text, video, voice, etc.) and circumstance-based traffic path optimization that can distribute the load. Regarding the management method, unnecessary signaling problems due to prior information sharing between MAGs and APs in the same access network are improved through traffic prediction analysis techniques, and according to whether or not they are moved within the overlapping AMAP domain. Since the routing path optimization procedure is or is not performed, there is an effect of reducing the handover delay time due to this.
