An apparatus and method of packet service hand over for WCDMA network to CDMA 1x network using DBDM station

摘要

The present invention uses a packet-switched services in the WCDMA network using DBDM (Dual Band Dual Mode) terminal 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.
