摘要
目的 提出一种实用于 WATM网络的越区切换方案 .方法 在分析 WATM控制结构的基础上 ,所提出的适应 WATM的越区方案 ,支持网络环境中的频繁切换事件 ,同时采用有效的用户呼叫控制机制 ,使越区切换产生的小区超载现象发生概率保持在可接受的限度内 .结果与结论 该方案不仅提高了性能 。
Aim\ To propose an improved scheme which is suitable for wireless ATM systems. Methods\ By on analysing the control architecture of Wireless ATM networks, the handoff scheme suited to WATM is proposed. It supports the frequent handoffand admission control of WATM. The probability of overload in base station can be kept within an acceptable limit. Results and Conclusion\ The analysis tell us that the scheme is not only improving performance, but also reduce the cost of communication devices.
