在未来的UMTS网络中，多媒体业务的异构性要求提供不同的QoS。同时，移动的用户和混合网络之间的信息无缝传送要求从无线到有线域的联网。然而，在学术界和工业界，在有线和无线网络的集成端到端的QoS提供仍然是一个挑战。在本文中，一个混合的无线WCDMA和有线IP为基础的DiffServ网络的建模研究的多媒体业务的端到端的QoS供应的资源分配。在无线域中，建立了包括物理层、链路层和网络层的跨层模型的数学模型。在跨层模型的基础上实现了连接允许控制方案，以确定不同业务的资源量。在有线域，我们定义了UMTS和DiffServ网络之间的映射，根据不同的QoS要求的QoS类。我们提出了一个带宽分配方案，以提供满意的分组丢失和延迟保证在区分服务网络。最终的端到端接纳控制方案结合了无线和有线域的资源分配和接纳控制。分析和仿真结果表明，所提出的资源分配和接纳控制方案的合作，在提出的混合无线和有线网络，以保证端到端的多媒体业务的QoS要求。
In the future UMTS network, the heterogeneous traffics of multimedia services demand various QoS provisioning. At the same time, the seamlessly conveying of information between mobile users and a hybrid network requires the networking from wireless to wireline domains. However, in both academia and industries, the end-to-end QoS provisioning in the integration of wireline and wireless networks remains a challenge. In this paper, a modeling of a hybrid wireless WCDMA and wireline IP-based DiffServ network is presented to investigate the resource allocation for end-to-end QoS provisioning for multimedia services. In the wireless domain, the mathematical modeling of the cross-layer model including the physical layer, the link layer and the network layer is built. The connection admission control scheme is implemented based on the cross-layer model to determine the amount of resource for different services. In the wireline domain, we define the mapping of QoS classes between UMTS and DiffServ networks according to different QoS requirements. We propose a bandwidth allocation scheme to provide satisfactory packet loss and delay guarantee in DiffServ networks. The final end-to-end admission control scheme combines the resource allocation and admission control in both wireless and wireline domains. The analytical and simulation results show that the proposed resource allocation and admission control schemes work cooperatively in the presented hybrid wireless and wireline networks to guarantee the end-to-end QoS requirements for multimedia services.
