A handover method of a mobile station (MS) in a mobile communication system having MSs and radio access stations (RASs), each of which includes an IEEE 802.16 standard-based medium access control (MAC) layer and an Internet protocol version 6 (IPv6)-based IP layer. The handover method includes the step of gathering IP network information of a neighbor RAS through a message exchange with a previous RAS. A target RAS for handover based on the gathered IP network information of the neighbor RAS is determined, after the target RAS is determined, the previous RAS tunnels data for targeting the MS to the target RAS, Then the tunneled data are received from the target RAS.
