Abstract
With the extensive use of the Internet and the rapid development of telecommunication technology, communication services become increasingly variety. Many new technologies promotes, such as one of the important applications PoC service over LTE based on the IP Multimedia Subsystem. According to this service requirement, blocking probability is desired to be low enough for the recall which occurs more often for PoC service. So in this paper, based on the analysis of the PoC over LTE system architecture, we propose to make a proper queuing model by using of the Queuing theory. Extended Erlang B formula is improved by implementing a more appropriate formula that is suit for the PoC over LTE. And the retrial calling percentage is concerned in the proposed model. The simulation result shows that the proposed method is more accurate and performs well to predict the blocking probability.
