随着5G技术的广泛应用，用户通信需求和应用场景的日益复杂，对差异化的服务质量（QoS,Quality of Service）有了愈发严苛的要求。本研究提出了一种基于5G QoS标识（5G QoS Identifier,5QI）与无线频率选择优先级（RAT Frequency Selection Priority,RFSP）联合的动态调度策略，通过改进的加权比例公平（Weighted Proportional Fair,WPF）调度算法融合接入管理-策略控制功能（Access Management-Policy Control Function,AM-PCF）动态策略机制，实现用户级与业务级的资源灵活分配。设计分层分级网络保障模型，为不同用户分配差异化的5QI和RFSP调度权重。测试结果表明，保障用户平均速率、视频播放质量等关键性能均优于普通用户，验证了差异化调度策略在复杂场景下的有效性。
Abstract：With the widespread adoption of 5G technology and the increasing complexity of user communication demands and application scenarios, there are growing stringent requirements for differentiated Quality of Service(QoS). This study proposes a dynamic scheduling strategy based on the joint optimization of 5G QoS Identifier(5 QI) and Radio Access Technology(RAT) Frequency Selection Priority(RFSP). By integrating an improved Weighted Proportional Fair(WPF) scheduling algorithm with the dynamic policy mechanism of the Access Management-Policy Control Function(AM-PCF), flexible resource allocation at both user and service levels is achieved. A hierarchical network assurance model is designed to assign differentiated 5 QI and RFSP scheduling weights to diverse users. Test results demonstrate that key performance metrics, including average data rate of prioritized users and video streaming quality, significantly outperform those of regular users, validating the effectiveness of the differentiated scheduling strategy in complex scenarios.
