本文提出了一种支持异构网络中应用程序始终最佳连接（ABC）服务质量（QoS）的机制。异构网络由IEEE 802.11e WLAN和IEEE802.16d WiMAX接入网络组成。网络中的用户设备(UE)具有WLAN和WiMAX接入能力。通用虚拟链路层 (GVLL) 位于 UE 中的 WLAN 和 WMAN MAC 层之上，根据 QoS 支持决定最佳服务接入网络。根据吞吐量、丢包率、延迟等 QoS 参数动态选择最佳接入网络。这项工作的主要重点是为异构网络中的可变比特率 (VBR) 多媒体服务提供 QoS。仿真结果表明，由于异构性的支持，网络中用户的性能在吞吐量、时延、呼叫准入等方面都有显着的提高。
This paper proposes a mechanism that supports always best-connected (ABC) quality of service (QoS) to the application in a heterogeneous network. The heterogeneous network consists of IEEE 802.11e WLAN and IEEE802.16d WiMAX access networks. The user equipment (UE) in the network is enabled with both WLAN and WiMAX access capabilities. The generic virtual link layer (GVLL) is placed above the WLAN and WMAN MAC layer in the UE, decides the best serving access network in terms of QoS support. The best access network is chosen dynamically based on the QoS parameters such as throughput, packet loss, and delay. The main focus of this work is to provide QoS for variable bit rate (VBR) multimedia services in a heterogeneous network. The simulation results show that the performance of the users in the network is improved significantly in terms of throughput, delay, call admission because of the support of heterogeneous nature
