公共安全和商业通信有不同的绩效目标。前者要求在正常时间和灾难期间具有高可用性（即低阻塞），而后者要求在正常时间具有高网络收入性能。因此，公共安全和商业通信传统上使用独立的网络，这导致频谱效率低下或性能不理想。本文提出了一种基于智能网络定价和呼叫准入控制的公共安全和商业频谱共享策略。我们提供了这种共享策略的性能目标的精确表征，即最大化商业收入，同时保证对公共安全呼叫的低阻塞概率。我们通过分析和仿真证明，我们的共享策略同时满足两种通信类型的目标
Public safety and commercial communications have distinct performance objectives. The former requires a high availability (i.e., low blocking), both in normal times and during a disaster, whereas the latter requires a high network revenue performance in normal times. Therefore, public safety and commercial communications traditionally use separate networks, which results in either spectrum inefficiency or unsatisfactory performance. In this paper, we propose a public safety and commercial spectrum sharing strategy via intelligent network pricing and call admission control. We provide a precise characterization of the performance objectives of such a sharing strategy, which is to maximize the commercial revenue while guaranteeing a low blocking probability to public safety calls. We demonstrate through analysis and simulation that our sharing strategy simultaneously satisfies the objectives of both types of communications
