Abstract

Spectrum sharing between operators with exclusive licensing have become a major concern for mobile network operators and regulators to respond to the growing spectrum demand of the multimedia applications. One of the important issues in spectrum sharing is to determine the potential benefit when multi-operators share the resources under certain mutual agreements. The paper focuses on dynamic spectrum sharing management in next generation cellular networks. We propose three loss network models and derive the closed form expression of blocking probability, each having specific level of cooperation and interaction. The analytical frameworks are presented to analyze the benefits due to multi-operator cooperation for spectrum sharing. This quantifies the operators' gains and degradations of operators engaged in cooperative arrangements. We also analyze the overall network performance in terms of spectrum utilization and present a detailed comparisons between the proposed analytical frameworks.

下一代蜂窝网络不同合作方案下的多运营商频谱共享模型
拥有独家授权的运营商之间的频谱共享已成为移动网络运营商和监管机构关注的主要问题,以应对多媒体应用日益增长的频谱需求。频谱共享的一个重要问题是确定多运营商在一定的相互协议下共享资源时的潜在效益。本文主要研究下一代蜂窝网络中的动态频谱共享管理。我们提出了三种损失网络模型,并推导了阻塞概率的封闭形式表达式,每种模型都具有特定的合作和交互水平。提出了多运营商合作频谱共享的分析框架。这量化了参与合作安排的运营商的收益和退化。我们还分析了频谱利用率方面的整体网络性能,并对所提出的分析框架进行了详细的比较。
