Research On CSFB Voice Solution For LTE System

With the development of communications technology,TD-LTE has become the biggest communications network worldwide.The LTE technology can not only meet the needs of high-speed wireless network but also enable the voice to be carried out at the same time.The CSFB is considered to be the best programme to carry out the voice in LTE system.This article would firstly analyse and research the LTE network structure over CSFB paging,attachment,call setup,down and other signaling processes.Thus the study orientation is established to focus on call failure,time delay and users' perception problems.And then,the core network equipment should be upgraded and the wireless network should be optimized.Additionally,it would statistically analyze and monitor the failure of signaling through the A interface signaling.In the end,the adjacent switching relationships are further configured.Finally through the comparative analysis and the test of the actual LTE network index,the quality of the network would be improved effectively and users' perception would be enhanced effectually.It would authentically provide a good valuable reference for the further research of the CSFB technology.
