Rerouting of direct information traffic under the WiMax-1/2 technology control in the case of licensed frequency spectrum overload ensures communication continuity in the smart city's critical infrastructure. The support of such a process in the WiMax-1/2 cluster has its specificity, worthy of analytical formalization. The article presents a mathematical apparatus that allows the average service duration of an information message during its transfer from the terminal to the WiMax-1/2 base station to be estimated. Unlike analogues, the presented concept adequately describes the investigated process for any number of terminals, taking into account both the queuing effect on their side and the functioning of the cumulative query transmission mechanism inherent in WiMax-1/2 technology. Therefore, the proposed mathematical apparatus, describing the process of servicing an information message, takes into account both the average duration accompanied by potential collisions in the process of sending a request for the allocation of communication resources for its transmission to the base station, and the average duration of the information message's stay in the terminal queue. Experimental studies demonstrated the adequacy of the proposed mathematical apparatus for describing the investigated process. The experimental section also formulates the optimization problem of the investigated process resulting from the management of competitive access parameters.
在授权频谱过载的情况下，在WiMax - 1/2技术控制下重新路由直接信息流量可确保智慧城市关键基础设施中的通信连续性。WiMax - 1/2集群中对这一过程的支持有其特殊性，值得进行分析形式化。本文提出了一种数学工具，可用于估计信息消息从终端传输到WiMax - 1/2基站期间的平均服务持续时间。与类似方法不同，所提出的概念充分描述了任意数量终端的研究过程，同时考虑了终端侧的排队效应以及WiMax - 1/2技术固有的累积查询传输机制的运行情况。因此，所提出的描述信息消息服务过程的数学工具，既考虑了在向基站发送其传输所需通信资源分配请求过程中伴随潜在冲突的平均持续时间，也考虑了信息消息在终端队列中的平均停留时间。实验研究证明了所提出的数学工具对于描述研究过程的充分性。实验部分还提出了因竞争接入参数管理而产生的研究过程的优化问题。
