Integration of wireless and mobile networks to new generations constitutes a heterogeneous system, this is the case of LTE and WiFi networks. In this paper, we study and analyze the optimal performances of this system regarding the SINR(Signal Interference Noise Ration), the blocking probability and the user communication loss. The user mobility is represented by random wayPoint(RWP) model and users terminals equipped with multiple accesses interfaces. We have established a Markov chain to

So we have proposed an average value of the signal power emitted in down-ling voice, the blocking probability of system connections. mobile networks such the LTE and the Wi-Fi based on the signal power emitted by down-ling voice, allowed us to discover the dynamic evolutions of the system related to the SINR. The parameters related to the SINR such as the blocking probability are estimated with rates approaching the 40% bar. As future works, we plan to estimate the same sensitivity factor when we consider the performances of the system related to the bit rate.
