A random-access algorithm based on statistics waiting in LTE-M system

摘要

LTE-M, which is an abbreviated version of LTE-MTC(Machine Type Communication) can be said to have a variety of applications, including a large number of heterogeneous interconnection of large-scale network equipment. One of the most prominent problems is that the machines may have a large amount of access requests in a short time, which can easily lead to network congestion. At present, the contention-based random access scheme is designed for the traditional cellular network, but it is not suitable for carrying a large number of machine communication services. This paper designs a random access resource allocation scheme to reduce the power consumption of the user equipment, so that optimizing the random-access process. In this scheme, we analyze the throughput, access success rate, and delay, then a comprehensive evaluation of the effectiveness of the program is made.
