Random-access performances measures evaluation with the concept of virtual preamble

Now rapid growth of number of the devices communicating among themselves in LTE (Long-Term Evolution) networks and also increase in volume of transmitted data is observed. The task of reduction of signal and user load, which is serviced by communication networks is relevant. For this purpose algorithms of the simplified interaction between the user devices and a network are being developed and implemented to minimize the spent network resources. In this paper the session initiation procedure between the User Equipment and the LTE eNodeB is analyzed. The problem of the small data transmission formed by the Machine-To-Machine (M2M) connections can be solved by using a Random Access Channel (RACH) for session initiation. Such solution was proposed in the technical report 37.868 of 3GPP (3rd Generation Partnership Project) consortium. For a RACH session initiation procedure it is necessary to evaluate preliminary measures such as access delay, access success probability, access failure pobability, statistics on number of preamble transmissions in case of successful access. In this paper we propose formulas for all listed measures estimation using the virtual preambles approach. Numerical analysis shows the accuracy of the proposed analytical model in the form of the Markov chain. © 2019 Author(s).
