蜂窝网络向动态、密集和异质网络的演进给小区资源优化带来了新的挑战,特别是在业务量不平衡的区域。已经提出了许多负载平衡方案来解决这一问题;然而,它们以被动的方式运行,限制了它们满足顶级体验质量需求的能力。为了应对这一挑战,我们提出了一种新的主动负载均衡方案。我们的框架学习用户的移动性,并要求联合统计数据,以便在用户停留在轻负载小区期间主动缓存未来的内容,从而实现体验质量最大化和负载最小化。进行了系统级仿真,并与最先进的无功方案进行了比较。
Evolution of cellular networks into dynamic, dense, and heterogeneous networks have introduced new challenges for cell resource optimization, especially in the imbalanced traffic load regions. Numerous load balancing schemes have been proposed to tackle this issue; however, they operate in a reactive manner that confines their ability to meet the top‐notch quality of experience demands. To address this challenge, we propose a novel proactive load balancing scheme. Our framework learns users' mobility and demands statistics jointly to proactively cache future contents during their stay at lightly loaded cells, which results in quality of experience maximization and load minimization. System level simulations are performed and compared with the state‐of‐the‐art reactive schemes.
