[srsran-users] ue/enb dedicated bearer support ?

[alexander.serkin at gmail.com]

Got that working finally with the following qci=3 section:

{
  qci=3;
  pdcp_config = {
    discard_timer = -1;
    pdcp_sn_size = 12;
  }
  rlc_config = {
    ul_um = {
      sn_field_length = 10;
    };
    dl_um = {
      sn_field_length = 10;
      t_reordering    = 45;
    };
  };
  logical_channel_config = {
    priority = 15;
    prioritized_bit_rate   = -1;
    bucket_size_duration  = 100;
    log_chan_group = 1;
  };
  enb_specific = {
    dl_max_retx_thresh = 32;
  };
},

Many thanks again!
Cheers,
Alex

Thank you, Andre
Do anybody have an example for qci=3 or 1? There are a lot of parameters which I do not understand unfortunately.
Tried to copy qci=7 but got an errors in modify bearer messages. My area is EPC unfortunately.

Cheers,
Alex

dedicated bearers are supported but you have to add a QCI config to the drb.conf in the eNB.

Cheers
