下一代无线网络（NGWN）集中于不同无线电接入技术（RAT）的融合，从而为诸如IP语音（VoIP）和视频流之类的应用提供良好的服务质量（QoS）。异构网络是指在可扩展、可演进的集成异构网络上，使用户能够以正确的形式获取和共享所需的、及时的信息。负载均衡是异构网络中实现资源共享和IPQoS算法的重要手段，通过配置排队方式来提高网络的整体性能。现有的互通网络不能支持许多多媒体业务的带宽需求，这些业务超出了互通网络的容量。为了应对这些挑战，LTE是向第四代无线电技术迈出的一步，该技术旨在提高移动的电话网络的容量和速度。LTE有望成为能够支持甚高带宽应用的无线接入技术之一。323信令协议实现了三网（WiMAX - WLAN -LTE - IPQoS -LB）的混合耦合互通.提出了一种基于快速切换分层移动的IPV6（FHMIPV 6）协议的异构网络模型，该模型融合了WiMAX、LTE和WLAN技术，以提高QoS。对所提出的工作的多媒体应用的QoS参数（例如发送和接收的流量、RTP、响应时间、抖动、数据包端到端延迟、TCP延迟、以太网延迟、数据包延迟变化）进行了模拟并测量了其性能。
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 –LTE – IPQoS –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.
