    Hello and thank you in advance for answering my question.

    I am a beginner and experimenting with LTE-A system-level version 2 to learn it.
    I try to use the traffic model. I can implement it with no problem and draw the plots. However, when I change any parameter such as the packet size or packet arrival rate, the throughput does not change at all. What I did is as follow:
    1- copy the LTE_sim_main_launcher_demo_trafficmodels content in my own file.
    2- the correspong lines as follows are added to the file:
    LTE_config.traffic_models.usetraffic_model = true;
    LTE_config.traffic_models.type = ‘voip’;
    LTE_config.traffic_models.voice_size = 40*8;
    LTE_config.traffic_models.iit_voice = 1;
    LTE_config.traffic_models.iit_silence=0;

    could you please kindly help me to solve the problem.
    I appreciate your help

    Hello again
    I did more works and see that by changing the traffic type in hex_grid_tilted_traffic to voip and then running the program the config shows voip but still the UE shows fullbuffer. So I guess the reason why changing the parameters does not change the results is that the type is not voip yet. I did try everything in every related file that is possible to change the type and parameters such as voice size, interval, etc. but nothing seems to work. I stuck on this for more than 3 weeks. Can please someone kindly help me to make traffic model works.

    Really appreciate any help
