摘　　要：如何保证TD-LTE终端尽可能长时间驻留在TD-LTE网络,减少终端从2G、3G返回TD-LTE网络的时延,是当前TD-LTE网络优化的重点。主要研究如何优化空闲态参数设置,以提升TD-LTE终端空闲状态的驻留能力。通过应用空闲态参数调整策略,多款主流TD-LTE终端更易驻留,返回时延缩短6-10s。The TD-LTE network optimization focuses on how to keep TD-LTE terminal staying in TD-LTE network with more time and how to reduce the time delay of terminal from 2G or 3G to 4G network. The main research focuses on how to optimize the idle parameter settings in order to enhance the resident ability of TD-LTE terminal in idle state. By applying parameter adjustment policy in idle state, a lot of popular TD-LTE terminals are more likely to reside and the return delay shortens 6-10s.
