Facing the wireless access of massive terminals in the power grid and the access priority requirements of different power service terminals, it is very important to solve the random access problem in the long term evolution (LTE) network. This paper studies the random access technology under power LTE private network. Firstly, it analyzes the demand for massive terminal access to power and describes the types of power rich services. Combined with the characteristics of power service access, the random access algorithm in LTE private network mode Study. Finally, the performance of the proposed algorithm is simulated. The simulation results show that the proposed algorithm has better performance and can meet the access requirements of different access level services.
