Analysis on Optimization Schemes of Random Access in LTE-A Radio Access Networks with M2M Communications
As a large number of MTC devices try to access the radio resources in a very short period,the rapid growth in the number of machine-type communications(MTC) devices causes the radio access network(RAN) to overload.Several candidate schemes for RAN improvements for MTC have been under consideration for possible adoption in LTE-A by 3GPP.In the paper,several schemes to control the RAN overload coming from massive number of MTC devices were analyzed,and optimization schemes for further solution was designed.
