摘　　要：针对TD-LTE系统基站应用,提出一种Linux用户空间下的相对定时器池的实现方法。结合哈希表、相对定时算法等技术,实现大数量定时器的高效管理,以Linux系统定时器单位为定时器粒度,定时器池满足基站高层协议软件大数量并发任务的应用需求。For the requirement of high layer protocol software in TD-LTE system eNodeB, this paper proposed a new implementation of a relative-timer pool in the user space. Combined with hash list and relative timing appointment , implement a relative-timer pool to manage large number of timers. The relative-timergranularity is 100 milliseconds and timer pool meets thelow latency of the application requirements for high-layer protocol software, meanwhile the efficient management of a number of timers.
