Next Generation Wireless Network (NGWN) will be composed of multiple Radio Access Technologies (RATs) and domains. Radio Network Selection (RNS) is the mechanism which decides how to select the most suitable RAT based on the discovered accesses, QoS constraints, operator policies, user preferences and available system capacity and utilization. Optimizing the selection process is an important issue of research, which leads to reduction of network signaling and mobile device power loss and on the other hand improves network Quality of Service (QoS) and Grade of Service (GoS). This paper presents and designs a multi criteria RNS solution that considers an environment with a co-existed WWAN, WMAN, and WLAN.
