Solution to frame losses due to fiber cuts

Hi All.

If we are having frame losses due to fiber cuts.

Is there a way to reduce them from radio side?

Any recommended feature?

I don’t think so…

Nothing on radio side can be done to improve frame loss…

Maybe header compressions to cater for the back up back bone capacity?

But how many UE support PDCP header compression for data?

They do it just for VoLTE.

I mean ROHC.

Normally during fiber cuts, TX team reroutes the data through another routes which cause congestion and frame losses.

So your approach will be in 2 ways from my opinion:

  1. Reduce the load during fiber cuts to reduce congestion on the backup routes
  2. Adjust packets priority according to your needs (Voice, Streaming, Browsing, Signaling and so on)

For example: you can limit max bitrate in 4G
