This paper presents the design and analysis of GPRS-WLAN Mobility Gateway (GWMG) for the integration of GPRS and wireless LANs (WLANs). The interworking between GPRS and WLANs is achieved by the GWMG that resides on the border of GPRS and WLAN systems. The design goal is to minimize the modifications in GPRS and WLANs as both systems are widely available in the market already. By deploying the GWMG, users can seamlessly roam among the two systems. Unlike other related work, the proposed GWMG

The proposed GWMG has also been implemented in a testbed comprising a commercial GPRS system. The results show that the GWMG could achieve the design goal to effectively integrate GPRS and WLANs.
