Research on the optimization of DRX mechanism of LTE system

This paper discusses the Long-Term Evolution (LTE) network architecture and key technologies, discontinuous reception (DRX) mechanisms of different systems and a comparison of the effects of using each DRX mechanism. Research is carried out on DRX mechanisms based on three kinds of optimization algorithms: semi-Markov control model, online learning adaptive DRX mechanisms, and adaptive control sleep cycle of DRX mechanisms. Finally, DRX mechanism of the adaptive control sleep cycle is simulated, and the advantages and disadvantages of the algorithm are analyzed. The results of this paper have good reference value for research into the LTE system.
