摘要

The current specifications of the Random Access Channel (RACH) of the Long Term Evolution (LTE) and LTE-Advanced (LTE-A) is not appropriate for Machine-to-Machine (M2M) communications. This is because the massive number of M2M devices will lead to low access rate and large access delay. This paper presents a new protocol, based on the Distributed Queuing (DQ) algorithm, for improving the performance of the Random Access (RA) procedure of LTE to support the M2M services. The proposed protocol, Distributed Queuing Access for LTE (DQAL), minimizes the opportunity of collision in the access phase for M2M. The reduction in the collision will turn in enhancing both the access rate and the access delay. Furthermore the presented scheme is designed to keep the normal access procedures of Human-to-Human (H2H) communication without any impact. Results show that the access delay is decreased to half of the LTE access delay and the access success probability approaches unity.
