SUPANET与WiMAX的无缝接入研究
|
摘要
针对现有的Internet在体系结构上存在着用户数据传输平台层次结构复杂、传输效率低下和服务质量难以保证的缺点,四川省网络通信技术重点实验室提出了“单物理层用户数据传输与交换平台体系结构(SUPA)”。采用带外信令控制思想将用户数据传输与交换平台简化为单物理层结构,为用户提供有服务质量保证的、面向连接的传输服务。
SUPANET可能更多的在骨干网中应用,然后连接各种接入网,为用户提供数据传输服务。SUPA的最大优点就是通过带外信令技术和物理帧时槽交换技术,提供严格QoS能力保证的服务。而WiMAX自诞生之初就肩负为用户提供便捷的、高性能的,且带服务质量保证的宽带接入服务。所以,实现SUPANET和WiMAX的互联就成为现实需要,它们的结合能够使SUPA的触角延伸到更远的地方,能够将服务质量保证延伸到用户,真正为用户提供端到端带QoS保证的业务。能够在同一网络中同时开展语音、视频和数据业务,迎合“三网合一”的需求。
本文所设计的互联方案,采用网关连接SUPANET和WiMAX网络。采用带外信令技术,将网关划分成信控平面和用户平面。信控平面负责SUPA信令与WiMAX信令的相互转换,并根据具体的QoS需求建立端到端的虚连接。虚连接建立后,数据在用户平面中进行传输,网关对数据帧进行适配。同时,为了提高网络管理效率,创新性地将WiMAX基站集成到网关中来。
本文确立了互联方案的部署形式和工作流程,对互联关键设备——网关进行了详细的逻辑功能设计。详细设计了在进行网络互联时,网关在信控平面的信令流程和信令消息转换过程,并设计了信息单元的转换方法。根据网关的工作状态,制定了详细的网关状态转移图。最后,通过OPNET网络仿真软件,对方案进行了仿真实验。证明所设计的互联方案能够为用户建立端到端的虚连接,并通过虚连接提供严格的QoS保证,证明方案是正确可行的。
Sichuan Network Communication Key Laboratory (SC-Netcom Lab) introduced a novel architecture called SUPA (Single physical layer User-data transfer Platform Architecture), which can improve the user data transfer efficiency and overcome the shortcomings of existing architectures in Internet with regard to QoS provisioning. It use the out-band signaling concept to simplifie the user-data transfer platform (U-platform) into a single physical layer, which can greatly improve efficiency as well as QoS provisioning for user data in the U-platform.
SUPANET is used in the backbone network mormally. It interconnects all kinds of access networks and provding network services with QoS guarantee. The most advantage of SUPA is the concept of out-band signaling and ethernet-like physical frame timeslot switching. Morevoer, the purpose of WiMAX is providing wireless broadband access is convenient, high-performance and with QoS guarantee. So, SUPANET to be interconnected with WiMAX is practical needs. It can extens SUPA's scope and brings the end-to-end services with QoS providing to the users. It can provides all kinds of service simultaneous and meets the requirements of migration from existing separated cable TV, telephone switching network, and computer networks to a converged network.
The interconnection scheme which is established in this papaer using the Gateway connects the SUPANET and the WiMAX network. Using out-band signaling technology, the Gateway is divided into control-plane and user-plane. The control - plane in charge of the coversion of the signaling and building the end-to end virtual connection according to the specific QoS requirements. The user data transfer via the user-plane of the Gateway, and the Gateway converts the data format.,since the establishment of virtual connection. Meanwhile, in order to improve network management efficiency, Gateway has been integrated the WiMAX base station.
This scheme which was designed not only maintains the independence of SUPANET and WiMAX, but also provides the end-to-end services with QoS providing.
In this paper, the deployment of the interconnected network and the specific workflow is established. The detailed logci design of the key equipment - Gateway has been done. A detailed coversion process of the singaling transfer under the control-plane has been designed, and the conversion method of infromation unit's translation has been designed. The deatail state transtions of the Gateway have been established too. Finally, a simulation has been done under the OPNET application, and the result shows that the interconnection scheme is correct and work, it can provide the end-to-end service with QoS guarantee between SUPA's user and WiMAX's user.
