Abstract
Nowadays, wireless packet data services are provided over Wireless WAN (WWAN), i.e., cdma2000 1x/1xEV-DO mobile networks and Wireless MAN (WMAN) is being standardized for users to demand higher data rate services. WMAN can provide high data rate services, but its service coverage is relatively small. If WMAN may be integrated with WWAN, users are able to choose the optimal service according to service areas and get seamless services while they are moving around. At the same time, it is cost-effective for operators to construct and maintain the integrated network. In this paper, we propose an interworking scheme for the purpose of effectively integrating WMAN and WWAN. The proposed scheme adopts a tightly-coupled architecture for unified authentication/accounting and seamless services. In addition, we develop a performance model for handoffs between WMAN and WWAN. Through extensive simulations, it has been validated that the proposed scheme reduces packet losses dramatically compared with the loosely-coupled scheme.
