In this paper, we have developed an efficient channel assignment scheme using fractional guard channel for utilizing the limited radio recourses efficiently and seamlessly by providing buffer for good-quality signal calls to improve the quality of service. Two models are proposed to prioritize good-quality handoff calls over poor-quality calls. The expressions for blocking probability, call dropped probability of handoff calls, utilization of channels and buffer are obtained for a cellular radio network. Numerical simulation results for both the models illustrate the impact of different parameters on the key performance measures.

蜂窝移动网络中带缓冲区分数保护信道方案的性能分析

在本文中，我们开发了一种有效的信道分配方案，该方案使用分数保护信道，通过为高质量信号呼叫提供缓冲区来提高服务质量，从而高效，无缝地利用有限的无线电资源。提出了两种模型来优先考虑优质切换呼叫和劣质呼叫。对于蜂窝无线网络，获得了阻塞概率，越区切换呼叫的掉话概率，信道利用率和缓冲器的表达式。两个模型的数值模拟结果说明了不同参数对关键性能指标的影响。
