摘 要: 高可靠低时延通信(ultra reliable and low latency communication,URLLC)具有高可靠性和低时延的传输特性,针对此类业务的建模和性能评估是进行通信系统设计和规划的实际需求。本文采用包括会话层和分组层的两层模型对URLLC业务进行建模,会话层通过会话间隔和会话大小描述业务的会话请求特性,分组层的分组到达间隔和分组大小用于描述业务的分组特性,并针对配电自动化业务、车联网云计算游戏和增强驾驶业务进行建模和仿真,分析业务的数据速率。仿真结果表明,所采用的两层业务模型具有一定的准确性。
关 键 词: 通信技术;通信与信息系统;业务模型;两层模型;高可靠低时延通信(URLLC)业务

Abstract: Ultra reliable and low latency communication (URLLC) has the transmission characteristics of high reliability and low latency. The modeling and evaluation work of URLLC service is the actual requirement of communication system design and planning. In this paper, the URLLC service is modeled by a two-layer model including a session layer and a packet layer. The session layer describes the session request characteristics through the session arrival interval and the session size. The inter arrival time and the size of the packet are used to describe the packet characteristics in packet layer. The electricity distribution automation service, Internet of vehicles cloud computing game and enhanced driving service are modeled and simulated, the data rate of each service is analyzed as well. The simulation results show that the adopted two-layer service model has obtained a certain degree of accuracy.
Key words: communications technology; communication and information system; service model; two-layer model; ultra reliable and low latency communication (URLLC) service
