Within the Canadian telecommunications industry, we are witnessing the convergence of cellular service providers and Internet service providers aiming to provide an "always best connected" (ABC) service to deliver multimedia communications and contents to diverse subscribers using a variety of heterogeneous broadband wireline and wireless networks, the latter including 3G cellular, WiFi WLANs, WiMax, etc., referred as broadband wireless networks (BWNs) in this proposal. A common characteristic of these diverse networks is the use of the universal Internet Protocol (IP) to facilitate network interconnection, and industry is deploying IP multimedia subsystem (IMS) technology to provide interworking between these heterogeneous access network technologies and extend multimedia services over BWNs. Technologies do not currently exist to manage subscriber access to these diverse networks in a unified manner. An important requirement of multimedia applications is that the transport network needs to provide an appropriate level of quality of service (QoS) support to ensure acceptable reception quality. Therefore another challenge is to enhance BWN technologies for QoS support, and to enhance multimedia encoding/decoding to counteract the anticipated limit in QoS offered by some BWNs. The overall goal of this project is to develop technologies that enable delivery of ABC multimedia services to subscribers via heterogeneous BWNs interworked through an IMS. Specific objectives include the following: (1) Development of an access management framework to globally manage the identity and service profile of individual subscribers and facilitate efficient access to multiple BWNs for ABC service; (2) Development of scalable and error resilient multiple descriptive coding/decoding techniques for H.264 multimedia and joint optimization with advanced transport layer protocol; (3) Development of QoS support techniques for efficient real-time multimedia access over WiFi and WiMax networks and over heterogeneous BWNs interworked with a core-IP network through an IMS.  Our efforts will provide cutting edge technologies and train highly qualified personnel to satisfy the future needs of Canadian telecommunications industry.

在加拿大电信行业中，我们目睹了蜂窝服务提供商和互联网服务提供商的融合，旨在提供“始终最佳连接”（ABC）服务，以使用各种异构宽带无线网络，包括3G蜂窝网络，Wimax，Wimax，Wimax，Wimax，Wimax，Wimax，Wimax，Wimax，Wimax，Wimax，Wimax，Wimax，Wimax，WIM，将多媒体通信和内容交付给潜水员订阅者，以提供多媒体通信和内容。 （BWNS）在此提案中。这些不同网络的一个共同特征是使用通用互联网协议（IP）来促进网络互连，而行业正在部署IP多媒体子系统（IMS）技术，以在这些异质访问网络技术之间提供互操作，并扩展多媒体服务。当前不存在技术以统一的方式管理对这些发散网络的访问。多媒体应用程序的一个重要要求是，运输网络需要提供适当的服务质量（QOS）支持以确保可接受的接收质量。因此，另一个挑战是增强BWN技术的QoS支持，并增强多媒体编码/解码，以抵消某些BWN提供的QoS的预期限制。该项目的总体目标是开发技术，以通过IMS通过异质BWNS插件向订户提供ABC多媒体服务。特定对象包括以下内容：（1）开发访问管理框架以在全球管理单个订户的身份和服务配置文件，并支持有效访问​​多个BWN的ABC服务； （2）针对H.264多媒体和高级传输层协议的H.264多媒体和关节优化的可扩展性和误差的多个描述性编码/解码技术； （3）开发QoS支持技术，以通过WiFi和WiMax网络有效地实时多媒体访问以及通过IMS与Core-IP网络互动的异质BWNS开发。我们的努力将提供最先进的技术并培训高素质的人员，以满足加拿大电信行业的未来需求。
