Research on Optimization of PRACH Configuration Parameters Based on LTE Network

文中深入探讨了基于Long Term Evolution(LTE)网络的Physical Random Access Channel(PRACH)配置参数优化策略,特别是在中国电信与中国联合网络通信集团有限公司(简称“电联”)实施大规模载波共享的背景下,如何通过精细的PRACH参数调整、提升网络性能,确保用户体验,有效支持5G演进。通过理论分析与实际案例相结合的方法,该研究揭示了在共享网络环境中,合理配置PRACH参数对减少接入时延,提升系统容量,增强网络稳定性以及提高资源利用效率的重要性。此外,在2.1G频段重耕过程中,关注了如何平衡4G与5G业务需求,并通过优化PRACH设计应对了共存挑战。

This paper explores in depth the optimization strategy of Physical Random Access Channel(PRACH)configuration parameters based on Long Term Evolution(LTE)network,especially in the context of China Telecom and China United Network Communications Group Co.,Ltd.(referred to as“ITU”)implementing large-scale carrier sharing,how to improve network performance,ensure user experience,and effectively support 5G evolution through fine PRACH parameter adjustment.By combining theoretical analysis with practical cases,this study reveals the importance of reasonably configuring PRACH parameters in reducing access latency,improving system capacity,enhancing network stability,and improving resource utilization efficiency in a shared network environment.In addition,attention was paid to how to balance the demands of 4G and 5G services during the redevelopment of the 2.1G frequency band,and the coexistence challenge was addressed by optimizing the PRACH design.
