METHOD FOR HANDOFF OF RELATION FROM PORTABLE INTERNET TO CDMA2000 NETWORK

摘要

In the mobile internet CD Em A handoff method in 2000, this network is disclosed. Method, the portable Internet network (PIRAN: Potable Internet Radio Access Network) and a mobile packet data serving node of the Internet base station and CDMA2000 network (PDSN) handoff method in a heterogeneous network comprising AIG (Access Internet Gateway) which is connected between the method, to obtain a traffic channel in a) the mobile terminal PANID (Previous Access Network ID) comprising an Origination Message containing the information transmitted; b) the base station (BSS) over the PANID the mobile terminal is handed off from one network are (handoff) recognize whether one and the step of establishment of the radio traffic channel and the portable Internet base station and the mobile station; c) CDMA2000 PCF of the base station is determined using the IP of the PANID Anchor packet data serving node (PDSN), and comprising whether the handoff call from which the connection; d) step of the PCF performs a service IP information of the ACR that has been connected to the existing in the packet data serving node (PDSN), and wherein the packet data serving node (PDSN) is connected between the point in AIG; e) step of relaying the packet data serving node (PDSN) and AIG with PP interface by using the IP information of the ACR; f) performing a mobile terminal and a PPP configuration and with the AIG, AIG is a mobile terminal comprising a user authentication request to the AAA server in the existing network; And g) after the user authentication is completed, a step of implementing a handoff (handoff) the new data transmission with data that has been buffered for the connection is now through the ACR. Accordingly, the present invention is a previous session of the mobile terminal is maintained in accordance with carrying out the handoff between networks can be carefully followed in a handoff to integrate heterogeneous network system. In addition, effective implementation of the service interworking between heterogeneous networks with the portable Internet network via a minimal modification of the CDMA2000 infrastructure to identify the user as the service quality, and the movement pattern of the mobile terminal efficiently through the interlocking of the CDMA2000 network and the portable Internet network, layer without interruption by performing a handoff procedure for the enemy can support fast hand-off.
