针对下一代战术通信系统中基于虚拟小区布局的移动的子系统，提出了一种新的切换判决算法--多准则切换判决算法（MDA）。在该算法中，越区切换判定度量是来自接入点的接收信号强度测量、接入点的软容量以及接入点和基站收发器的相对方向和速度。接入点的软容量受环境中的干扰的影响。我们使用一个模糊推理系统来处理这些指标。我们比较我们的算法与接收信号强度为基础的切换判决算法。测试结果表明，隶属度阈值最低的MDA实现了最小的误呼次数，隶属度阈值最高的MDA实现了最小的呼叫阻塞率，前者的呼叫阻塞率仍在可接受的范围内，后者的误呼次数也在可接受的范围内。
A novel handoff decision algorithm, namely multicriteria handoff decision algorithm (MDA), for the virtual cell layout based mobile subsystem of the next generation tactical communications systems is introduced. In this algorithm, handoff decision metrics are received signal strength measurements from the access points, soft capacities of the access points, and relative directions and speeds of the access points and the base transceivers. Soft capacity of an access point is affected by the interference in the environment. We use a fuzzy inference system to process these metrics. We compare our algorithm with the received signal strength based handoff decision algorithms. Our tests have shown that MDA with lowest membership value threshold achieves minimum number of handoffs, and MDA with highest membership value threshold achieves minimum call blocking rate (GoS), where the call blocking rate is still in an acceptable level in the former case and number of handoffs is in an acceptable level in the latter case.
