当在大规模移动的通信系统中有一个以上的无线电信道可用于为移动的用户服务时，用于进行分配的策略对系统性能有影响。本文通过计算机模拟比较了五种不同分配策略的性能。已经发现，选择要在基站处分配的信道使得到使用相同信道的下一基站的距离最小的策略比最小化到两侧上的下一“使用中”基站的均方距离的策略执行得更好。此外，发现选择在信道搜索中遇到的第一个可用信道是产生相当好的系统性能的策略。
When more than one radio channel is available to serve a mobile customer in a large-scale mobile communications system the strategy used to make the assignment has an effect on system performance. Performance characteristics for five different assignment strategies obtained from a computer simulation are compared in this paper. It was found that the strategy that chooses a channel to be assigned at a base station so that the distance to the next base station using the same channel is a minimum, performs better than a strategy that minimizes the mean square distance to the next "in use" base stations on both sides. Also, it was found that choosing the first available channel encountered in a channel search is a strategy that produces reasonably good system performance.
