Performance evaluation of Push-to-Talk Application over LTE Networks
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 5
Abstract
Public safety has been using narrowband trunking systems for decades. These systems were designed with only voice calls in mind. Therefore, their data capabilities are limited. Long Term Evolution LTE has been selected as the platform for next generation public safety networks. It can support not only push-to-talk PTT but also pushto-multimedia. This paper applies queueing theory to evaluate the performance of PTT application over LTE networks. A proper queueing model based on PTT over LTE system is analyzed and implemented in SimEvents simulation. The results of the proposed mathematical model are compared with the simulation results for validation. Furthermore, since Erlang B formula is a general model, the simulation has been adopted to evaluate the system call blocking probability when a different type of calls such as push-to-send-picture is used in the system.
