Abstract: PURPOSE: A method for performing handover of a packet mobile communication network is provided to converts a wired/wireless channel of a mobile station if the mobile station located in a packet network supporting a mobile Internet protocol moves to a new area(cell) and requests handover, so as to prevent a packet loss and maintain communication. CONSTITUTION: If a mobile station moves to a new area, an RNC(Radio Network Controller)-1 of a serving network transmits a handover request signal to an RNC2 of a target network. The RNC2 generates a null traffic channel frame to the mobile station, to set up a traffic channel with the mobile station, and requests connection to a PDSN(Packet Data Service Node)-2. If a reply is received from the PDSN2, the RNC2 sets up a logical link with the PDSN2, and transmits a handover request reply signal to the RNC1. Packet data inputted to the RNC1 are transmitted to the RNC2 and stored. The RNC1 transmits a handover direction message to the mobile station, to notify the RNC2 of handover. The mobile station transmits a reply instruction to the RNC1. The mobile station transmits a reverse traffic channel frame or a traffic channel preamble to the RNC2, to notify the performance of handover. The mobile station transmits a handover completion message to set up a handover channel. The mobile station and the PDSN2 perform PPP(Point-to-Point Protocol) connection. The PDSN2 transmits an ICMP(Internet Control Message Protocol) router advertisement for notifying the mobile station of a self IP(Internet Protocol) address. The mobile station requests mobile IP registration to a PDGN/HR(Packet Data Gateway Node/Home Router). The PDGN/HR requests mobile IP release for deleting information of the mobile station to the PDSN1. The PDSN1 transmits a handover channel release signal to the RNC1. The RNC1 releases the handover channel between the RNC1 and the RNC2. The PDSN2 transmits a mobile IP registration reply signal to the mobile station. The PDSN2 transmits the packet data to the mobile station, to start packet data communication with the mobile station.
