Interworking between wireless LAN and CDMA2000

CDMA2000 and WLAN have different capabilities in distance range, data rate, and in other features. Combining CDMA2000 and WLAN will enable these WAN and LAN technologies to complement each other to enhance the available wireless network services. A possible architecture of interworking between CDMA2000 and wireless LAN is presented. The interworking architecture includes access control requirements and principles, and also authentication methods and charging requirements.
