enum EpsBearer::Qci q = EpsBearer::GBR_CONV_VOICE;

Hello,

I am trying to test any LTE example and vary the QCI value.

As per example, the lena-simple or lte-cqi-threshold,

in order to ativate a data radio bearer :

  // Activate a data radio bearer

  enum EpsBearer::Qci q = EpsBearer::GBR_CONV_VOICE;

  EpsBearer bearer (q);

  lteHelper->ActivateDataRadioBearer (ueDevs, bearer);

I am trying to change the Eps Bearer to any Qci value such as:

GBR_CONV_VOICE for qci=1

GBR_CONV_VIDEO for qci=2

GBR_GAMING for qci=3

GBR_NON_CONV_VIDEO for qci=4

NGBR_IMS for qci=5

NGBR_VIDEO_TCP_OPERATOR for qci=6

NGBR_VIDEO_TCP_GAMING for qci=7

NGBR_VIDEO_TCP_PREMIUM for qci=8

NGBR_VIDEO_TCP_DEFAULT for qci=9

The outputs remains the same and nothing changes  while changing the QCI / Eps Bearer.

Any Solution that emphasis on the effect of qci ?!

You would see a difference if the CQI was used e.g. for scheduling. Also it depends on the scenario, e.g. if you have only one UE able to use all available bandwidth, then CQI would not make any difference.

The default scheduler is Proportional Fairness, which does not use CQI.

I am talking about the QCI values and not the CQI.

if i want to visualise the difference in the outputs while changing the QCI values in the example "lena-simple" 

what should i do?

Hi Konstantinos
I also have the same question I. e. even if I am using different QCI Bearer for different UE still it is allocating same resources to each UE. What changes should I make to visualize the changes in resources allocation for different QCI.

Thank You.
