Due to the problem of different QoS granularity in integrated UMTS/WLANs, how we construct effective QoS mapping mechanism for user satisfaction is essential during the changes of access networks, so called, handoffs. So in this paper, a novel dynamical QoS mapping mechanism based on Application Service Map (ASM) is proposed in order to support end to end QoS and minimize the service quality degradations. Based on the access network corresponding classification methods, all services can be categorized by priority and subdivides each grade of service into three sub-levels based on ASM. The proposed mechanism contains a two-way QoS mapping adjustment mechanism and it can dynamically adjust the QoS mapping relationship to optimize the allocation of resource according to present load condition of network. And a two-level QoS mapping selection algorithm based on the sub-level and priority of QoS service is used in the two-way QoS mapping adjustment mechanism to adaptively select more refined QoS. As an experimental result, the proposed mechanism can greatly improve the utilization of network resource and the user's satisfaction.

“…Mobile IP will provide major benefits, including application transparency and the possibility of seamless roaming. Hybrid coupled interworking is very much useful in the case of resource sharing and traffic management and thereby enhances the QoS performance [7]. In this paper a novel hybrid coupled interworking model that integrates Worldwide Microwave Access network (WiMAX), a Wireless Local Area Network (WLAN) and a Long Term Evolution network (LTE) is proposed with IPQoS and LB [8].…”

Next Generation Wireless Networks (NGWNs) focus on convergence of different Radio Access Technologies (RATs) providing good Quality of Service (QoS) for applications such as Voice over IP (VoIP) and video streaming. A heterogeneous network is to enable the users to obtain and share necessary and timely information in the right form over integrated heterogeneous network which is scalable and evolvable. Load balancing which is a significant method to achieve the resource sharing and IPQoS algorithm in the heterogeneous network is used to improve the overall performance of the network by configuring of queuing methods. Existing interworking networks couldn't support the bandwidth demands of many multimedia applications which exceed the capacity of the interworking network. To meet the challenges, LTE is a step toward the 4th generation of radio technologies designed to increase the capacity and speed of mobile telephone networks. The LTE promises to be one of the wireless access technologies capable of supporting very high bandwidth applications. In this paper a hybrid coupled interworking of three networks (WiMAX -WLAN -LTEIPQoS -LB) using H.323 signaling protocol is proposed. Heterogeneous network model based on Fast handover Hierarchical Mobile IPV6 (FHMIPV6) protocol that integrates the WiMAX, LTE and WLAN technologies is proposed to improve QoS. The QoS parameter in terms multimedia application such as traffic sent and received, RTP, response time, jitter, packet end -to-end delay , TCP delay, Ethernet delay, packet delay variation, of proposed work were simulated and its performance are measured.

“…This will definitely bring several advantages for all parties including mobile users, network providers and service providers. On one hand, users will benefit from the coverage and characteristics provided by the different networks by allowing them to seamlessly connect, at any time and any place, to the access network that offers the "best" possible quality and the most economical service, while network and service providers will deploy the most economical technologies and infrastructures based on the offered services [10]. To compensate ubiquity and interoperability problems between these different networks, we should study procedure of handover management which insure for mobile user to move from one network to another without interrupt his active communication [11].…”
