Executive Summary

The main methods used to implement WLAN-3G inter working are: the mobile IP methods, the emulator method, and the gateway method. Each one of these methods enjoys some pros and suffers from some cons. In this paper, it is demonstrated to evaluate certain aspects of WLAN-3G inter working. Here, case studies are addressed: based on results of the current researches and some simulations developed in this paper; in order to evaluate some aspects of inter working methods. Basically, in this paper, the main methods used to implement WLAN-3G inter working are evaluated from the handover delay point of view.
