Research on WLAN-3GPP interworking is regarded as a case of implementation of heterogeneous networks which are the tendency of future mobile communication systems. The paper describes a WLAN-3GPP interworking system, describes the issues existing in current networking selection procedures and analyses the disadvantages and advantages of the current solutions in detail. The efficiency of network selection determines the performance of system accessing, especially handover. Finally, two schemes are proposed to improve the procedure to meet the requirements of seamless handover when performing vertical handover between WLAN and UMTS.
