Recent trends are showing fast convergence of mobile and wireless communication networks with internet services to provide ubiquitous access to network users. It is envisioned that these next generation wireless networks will be supported by an all-IP based infrastructure with the support of heterogeneous wireless access technologies such as UMTS, WLAN, WiMax, etc. These heterogeneous access networks differ in many properties and characteristics such as data rates, coverage, and capacity, as well as mobility, QoS and security requirements. Since these networks are complementary to each other, their integration will empower mobile users to be connected to the all-IP based infrastructure using the best available access network during roaming.
