The Goals of Next Generation Mobile
Wireless Lan (WLAN) Low cost Unlicensed free frequency brand High data rate up to 100 mbps
Universal Mobile Telecommunications System(UMTS) standard of Third-Generation (3G) cellular systems providing wide coverage. universal roaming service.
A Standard WLAN does not support: Security and Billing While UMTS does.
The literature Review and Motivation
But Small Coverage such as schools, offices, airport, etc.
but limited data rate up to 2 Mbps and very expensive.
The Integration Open Coupling Loose Coupling Tight Coupling Very Tight Coupling

Scenario Features
1 Common billing and Customer Care
2 Scenario 1 + Common Authentication
3 Scenario 2 + Access to 3G packet-switch based services
4 Scenario 3 + Service Continuity
5 Scenario 4 + Seamless service continuity
6 Scenario 5 + Access 3G circuit-switch based services with
seamless mobility

Motivation Better Service
Combined network will support: very high data rates in the WLANs hotspots, high mobility and internet access availability
through UMTS Increase the 3G cellular network capacity and
profitability significantly. To identify an architecture that can provide better
performance and a flexible interworking based on Internet applications

Prospective research work may include how to reduce the http page and ftp file upload response time for loose coupling.
Conclusion
Future Work
Both coupling have advantages depending on the application. For VoIP loose coupling with the G729A codec provides lower jitter
and end to end delay.To implement tight coupling changes to the protocols used in WLAN
are necessary.Loose coupling may be implemented more readily and provides
simplicity and efficiency for 3G/WLAN integration.
