An efficient and fair packet scheduler is very important to guaranty the cellular network quality of service (QoS). In general, classic packet schedulers follow static rules based on priorities. Unfortunately, static rules may cause unfair resource distribution. We present and analyze FuzSy, a cellular network packet scheduler based on the quality of service and fuzzy logic. Instead of following static prioritization rules, it prioritizes traffic classes that have a higher risk of not reaching QoS requirements. Its dynamic priority changes any traffic class in case of performance decrease risk. Based on network metadata, FuzSy uses fuzzy logic to decide about prioritization. We conducted simulations in a 4G network. FuzSy achieved QoS requirements and network fairness for all classes. One of FuzSy’s significant advantages is the fairness guaranty that solutions contained in other works do not garantee. We show that FuzSy can be used in any kind of cellular network because it is straightforward to have its parameters adjusted. In the future 5G networks, for example, FuzSy may be helpful due to a large number of heterogeneous connected devices and different kinds of applications. The FuzSy scheduler use may achieve the QoS, and the fairness guarantees since its concept is independent of technology, and it is usable in any kind of network.

有效且公平的数据包调度程序对于确保蜂窝网络服务质量（QoS）非常重要。通常，经典的数据包调度程序会根据优先级遵循静态规则。不幸的是，静态规则可能导致不公平的资源分配。我们介绍并分析基于服务质量和模糊逻辑的蜂窝网络数据包调度程序FuzSy。它没有遵循静态优先级分配规则，而是对那些未达到QoS要求的较高风险的流量类进行优先级分配。它的动态优先级会在性能降低风险的情况下更改任何流量类别。基于网络元数据，FuzSy使用模糊逻辑来确定优先级。我们在4G网络中进行了仿真。FuzSy满足了所有类别的QoS要求和网络公平性。FuzSy的显着优势之一是公平保证，保证其他作品中包含的解决方案不被担保。我们展示了FuzSy可用于任何种类的蜂窝网络，因为可以直接调整其参数。例如，在未来的5G网络中，由于存在大量异构连接的设备和不同种类的应用，FuzSy可能会有所帮助。FuzSy调度程序的使用可以实现QoS，并且公平性得到保证，因为其概念与技术无关，并且可以在任何类型的网络中使用。由于存在大量异构连接的设备和不同类型的应用，因此FuzSy可能会有所帮助。FuzSy调度程序的使用可以实现QoS，并且公平性得到保证，因为其概念与技术无关，并且可以在任何类型的网络中使用。由于存在大量异构连接的设备和不同类型的应用，因此FuzSy可能会有所帮助。FuzSy调度程序的使用可以实现QoS，并且公平性得到保证，因为其概念与技术无关，并且可以在任何类型的网络中使用。
