AN APPARATUS AND METHOD OF PACKET SERVICE HAND OVER FOR WCDMA NETWORK TO CDMA 1X NETWORK USING DBDM STATION

摘要

invention DBDM (Dual Band Dual Mode) terminal for use in WCDMA network packet switch services use will be in the packet or handover apparatus and method for a subscriber using packet-switched services of the CDMA network to the CDMA network in a WCDMA network using a DBDM terminal using the Mobile IP function to move to the other network for continuity of service. The invention is responsible for the WCDMA mobile IP network and perform a function for providing the packet service, and performs the gateway (Gateway) function for matching with the Internet / Intranet (Internet / Intranet), the current location information of the DBDM terminal to maintain, and the GGSN / HA that tunnels / routing the packet to be provided to the terminal, Mobile IP service of the subscriber to the authentication node to the authentication / authorization and billing and subscriber management system in the packet with the address assigned to process the AAA server, etc. and having a, CDMA 1X packet network is a handover from the WCDMA network to the CDMA network using separate the DBDM terminal that provides continuity of the packet service to be able to perform the handover to a CDMA 1X packet network in WCDMA networks without additional equipment The apparatus and methods.
