AbstractAdvanced wireless mobile communication systems such as 3rd Generation (3G) provide users high mobility but less data rate. On the other hand, WLAN systems offer high data rate with less mobility. However, there is a need for public wireless access: to cover the increasing demand for high data-intensive applications and to enable smooth online access to corporate data services in hot spots. Therefore, one possibility to supply this need could be achieved through the interworking between both technologies, i.e., WLAN-3G interworking together. The main focus is to present and describe WLAN-3G interworking: aims, features, architectural methods, and development for future high data rate networks. In addition, the research provides an analytical model and a simulated model that can be used for evaluating the performance of the mobile IP method, the gateway method, and the emulator method which are used to implement WLAN-3G interworking. As a consequence, the mobile IP method suffers from high handover delay. The gateway method has lower handover delay than the mobile IP method. However, the emulator method has the lowest handover delay.
