Due to the difference between the access technologies and the disparity of application's QoS requirements, there is a significant need to make available a unified approach that integrates all useful access networks. The fourth generation wireless networks will envision flexible and adaptive integration of network technologies to enable mobile station to seamlessly roam between access networks. These networks should not only provide the commonly known Internet services, but also should transport the traditional voice service and other real-time applications. Eventually, they should allow more advanced broadband multimedia services with varying QoS requirements (e.g., preferred low handoff delay, high bandwidth utilization, low new call and handoff blocking probability, low loss packets and high packet rate).
