IP化基站无线Mesh组网构架

Wireless Mesh Architecture for IP Based Base Stations

无线网状网(WMN)融合了无线局域网(WLAN)和AdHoc网络的性能优势,具有容量大、速率高、覆盖范围广等特点,成为宽带无线接入的一种有效手段,可以灵活地应用于多种无线环境。目前,蜂窝移动通信系统中各基站间的有线连接,使得传统的蜂窝移动通信系统难以满足部署方便、成本低廉、高可扩展性、高可靠性等指标。为适应下一代移动通信网络扁平化、简单化的发展趋势,IP化基站的无线Mesh组网架构是可选方案之一。支持IP化基站自组织的关键技术包括按需的基站自组织技术、联合无线资源调度机制、路由技术、安全技术、网络管理技术等。

Combining the performance advantages of both Wireless Local Area Network （WLAN） and Ad Hoc network, the Wireless Mesh Network （WMN） is characterized by large capacity, high rate and wide coverage. It has become an effective means for broadband wireless access and can flexibly be applied in various wireless environments. The wired connections between base stations in traditional cellular mobile communications systems can no longer satisfy the requirements for flexible deployment low cost, high scalability and good reliability. The wireless Mesh architecture for IP based base stations is thus introduced as an optional solution to support the flat and simplified next generation mobile communications network. The key technologies used to support self-organizing of IP based base stations involve several aspects, including self-organizing of base stations on demand, joint radio resource scheduling mechanism, routing, security and network management.
