摘要
论文针对VoIP实时通信业务,根据其对延迟性能的需求,分析了时隙分配对延迟性能的影响,并对其进行了建模分析。结果表明,与传统的时隙位置连续分配相比,时隙均匀分配能显著提高业务的延迟性能。文中给出了MF-TDMA的通信系统中,提高延迟性能的解决方案,分析了两种业务下时隙均匀分配和时隙连续分配的延迟性能和丢包率。
The paper analyzes the impact of time-slot allocation method on the delay performance, especially for VoIP realtime services. According to the delay performance demand of real-time service, we give models and analysis. The results show that compared with traditional allocation method, the uniform time slot allocation method is better in improving delay performance. In MF-TDMA systems with long frame length, the paper presents the solutions of improving delay performance .Then we analyze the performances of delay and packet dropping with two traffics.
