摘　　要：为满足不同配电通信业务的服务质量要求,BS需要在时变网络条件下实时优化无线资源。提出一种基于级联深度网络的接入网无线资源边缘代理调度方法,将时频资源和发射功率分配给延迟耐受度不同的业务。核心网采用网元功能与专用硬件设备解耦的软切片方法,在保证负荷在规定时长内可靠切除的同时,提高了核心网服务器对不同业务的时空间复用能力。仿真结果表明,多业务并列运行时RTU与协控子站间的接入时延与TD-LTE专网相比降低40.76%,相邻第一第二信道间的功率泄露比均高于45 dB,满足毫秒级负荷切除业务分路整组动作时延和通信可靠性的要求。In order to meet the service quality requirements of different power distribution communication services,base stations need to optimize wireless resources in real time under time-varying network conditions.The paper proposes a cascaded deep network-based edge proxy scheduling method of access network wireless resource to allocate time-frequency resources and transmit power for the services with different delay tolerances.Furthermore,the core network adopts a soft slice method in which network element functions are decoupled from dedicated hardware devices.While ensuring that the load is reliably removed within a specified period of time,the core network server’s time and space multiplexing capabilities for different services are improved.The simulation results show that the access delay between the RTU and the co-control sub-station in the parallel operation of multiple services is reduced by 40.76%compared with the TD-LTE private network,and the power leakage ratio between the adjacent first and second channels is higher than45 dB.It satisfies the requirements of millisecond-level load removal service branching time delay and communication reliability for the entire group of actions.
