多业务支持是蜂窝网络和无线局域网（WLAN）之间互通的重要动机。两个网络的互补优势可以有效地结合起来，以增强服务提供。在本文中，我们研究如何正确地分配整体资源的综合网络会话，流媒体和互动服务。该策略利用了突发视频流和弹性数据流量等基本流量特性。通过采用区分服务的会话分配和通过垂直切换的会话迁移的接纳控制，系统性能比WLAN优先的方案有显着提高。
Multi-service support is an important motivation for interworking between the cellular network and wireless local area networks (WLANs). The complementary strengths of the two networks can be effectively combined to enhance service provisioning. In this paper, we investigate how to properly allocate the overall resources in the integrated network to conversational, streaming, and interactive services. The proposed strategy exploits the essential traffic characteristics such as bursty video streams and elastic data traffic. The system performance is significantly improved over the WLAN-first scheme by applying admission control with service-differentiated session assignment and session migration via vertical handoff.
