Abstract

This paper focuses on an advanced congestion control scheme for M2M(Machine-to-Machine) communications in 3GPP LTE-Astandard. A large number of MTC(Machine-type-Communication) devices try to access to LTE-A networks and send data to thenetworks all at once. In this characteristics, M2M communications will bring the serious network congestion problems into LTE-Acellular networks. To solve this critical problem, a congestion control mechanism will be required and it has been studied since Rel-10LTE-A systems based on backoff mechanism for mobility management and session management. In this paper, we briefly introducethe main concept and operation about the congestion control scheme in 3GPP LTE-A standard. Also, simulation results for the basiccongestion control and advanced congestion control scheme in MTC communication environment are provided and the improvementdirection is considered in future 3GPP LTE-A standard.
