System and method for coupling between mobile communication system and wireless local area network

摘要

A system for providing communication when a mobile station moves between a wireless LAN system and a mobile communication system. A packet data service node provides a packet data service between an IP network and the mobile station when the mobile station accesses the mobile communication system. A packet control function provides the packet data service between a correspondent node connected to the IP network and the mobile station when the mobile station previously connected to the mobile communication system is connected to an access point, and provides the packet data service between the correspondent node connected to the IP network and the mobile station when the mobile station previously connected to the access point is connected to a base station system. An interworking server connected between the access point of the wireless LAN system and the packet control function of the mobile communication system.
