提出一种独特的无线IP接入网结构。此结构突破了传统的接入网管理域概念,直接在最靠近无线传输点的基站控制器上为用户提供IP网络接入,构成分布式的全IP无线接入网。其支撑协议MPPP(MobilePoint-to-PointProtocol)可充分体现用户移动的个性特征,构成动态逻辑接入网管理域。提出的快速平滑切换可保证用户在大业务量、频繁高速移动中的无损IP业务。
Proposed a unique wireless IP access network structure. This structure breaks through the traditional concept of access network management domain and provides users with IP network access directly on the base station controller closest to the wireless transmission point to form a distributed all-IP wireless access network. Its support agreement MPPP (MobilePoint-to-PointProtocol) can fully reflect the personality characteristics of mobile users to form dynamic logical access network management domain. The proposed fast and smooth switching can ensure users’ lossless IP services in large traffic and frequent high-speed moving.
