摘　　要：为了使模拟用户和实际用户行为一致,提出一种5G终端模拟系统中随机接入的实现方法,属于通信技术领域。主要从系统开销资源和时间复杂度两方面对5G终端模拟系统中随机接入模块进行设计。使用线程池的思想,可有效减少系统开辟线程资源消耗的时间,并能节省系统20%~50%的资源开销。在用户线程资源调度上,采用两个链表数据结构,处理数据的时间复杂度由传统的O(N)降低到O(1),大大增加了数据传输的速度,且按照R15版本协议标准成功完成5G终端模拟系统的随机接入过程。In order to make the behavior of analog users and actual users consistent,this paper proposes a realization method of random access in 5G terminal simulation system,which belongs to the field of communication technology.This paper mainly designed the random access module of 5G terminal simulation system from two aspects of system cost resource and time complexity.This paper mainly used the idea of thread pool,which could effectively reduce the time of the system to open up thread resources,and ultimately save 20%-50%of the system’s resource overhead.In terms of user thread resource scheduling,two linked list data structures were adopted.The time complexity of data processing was reduced from the traditional O(N)to O(1),which greatly increased the speed of data transmission.In addition,the random access process of 5G terminal simulation system was successfully completed according to R15 version protocol standard.
