摘要

摘要: 傳統(tǒng)的靜態(tài)頻譜分配方式難以適應(yīng)未來無線通信業(yè)務(wù)的發(fā)展需求，可能導(dǎo)致運營商業(yè)務(wù)和用戶服務(wù)質(zhì)量受到限制。針對此問題，該文建立了一個包括頻譜租賃服務(wù)平臺層、運營商層及用戶層的多運營商頻譜共享模型。在該模型中，多個A類運營商將其多余頻譜放置在頻譜租賃服務(wù)平臺，供B類運營商租賃，B類運營商與多個A類運營商既競爭用戶又共享部分頻譜。該文形成了以各類運營商利潤最大化為優(yōu)化目標(biāo)，以A類運營商的頻譜出租量和B類運營商租賃的頻譜種類及數(shù)量為優(yōu)化變量的最優(yōu)化問題，并求得最優(yōu)解。仿真結(jié)果表明，所提策略在保證用戶服務(wù)質(zhì)量(QoS)的同時，顯著提高頻譜資源利用率，并使運營商利潤大幅增加。

Abstract: Traditional static spectrum allocation can not adapt to the future development of wireless communication services, leading to limited profits for operators and poor Quality of Service (QoS) for users. To solve the problem, this paper proposes a three-layer spectrum sharing model including operators, users, and a spectrum leasing platform, where A operators place their excess spectrum in the leasing platform for B operators to lease. This paper considers a situation where multiple operators cooperate to share portions of spectrum but compete to serve users, then the optimal spectrum leasing strategy is studied. The goal of this paper is to find the optimal leasing strategy for both A and B operators to maximize their profits while guaranteeing the QoS for users. Numerical results show that the proposed strategy not only improves the efficiency of spectrum utilization effectively but also shows a big advantage in increasing operators profits.
