SGER: Connection Admission Control and Network Pricing in Public Safety Spectrum Sharing

该项目解决了以下问题：（1）什么样的动态频谱共享机制为这两种类型的用户提供了最大的好处？ 公共安全用户的抢先频谱使用可能会给商业用户带来不必要的成本，因为商业用户的连接被切断。 在另一个极端，无论呼叫者类型如何，只要可用就分配信道的简单共享可能会对公共安全造成过高的阻塞。可以制定许多中间机制。 这些机制都可以与将总带宽划分为严格隔离的公共安全和商业子带的当前机制进行比较。(2)选择这些不同机制的成本是什么，对于公共安全用户来说是阻塞的，对于商业用户来说是经济成本？该项目正在制定方法，以便更准确地描述共享机制的好处，并制定更优化共享机制的技术。 利用强化学习和网络定价的方法正在应用于开发最佳共享机制的问题。这一努力将有助于量化动态频谱共享的好处，并向公共安全和商业用户提供共享概念将满足其各自需求的保证。

This project is addressing the following questions:(1) What dynamic spectrum sharing mechanisms provide the most benefit to both types of users? Preemptive spectrum use by public safety users may incur undue cost to commercial users which have their connections cut. At the other extreme, simple sharing that allocates channels whenever available regardless of caller type may incur too high a blocking to public safety. Many intermediate mechanisms can be formulated. These mechanisms can all be compared with the current mechanism that divides the total bandwidth into rigidly segregated public safety and commercial sub-bands. (2) What is the cost of choosing these different mechanisms in terms of blocking for public safety users and economic cost to commercial users?This project is developing methods that will allow a more precise characterization of the benefit of sharing mechanisms and techniques for more optimal sharing mechanisms. Methods that draw on reinforcement learning and network pricing are being applied to the problem of developing optimal sharing mechanisms. This effort will help quantify the benefit of dynamic spectrum sharing and provide assurances to public safety and commercial users that the sharing concept will meet their separate needs.
