Hello all.
What settings in a handset decides whether UE is Voice centric or Data centric?
Based on what criteria a UE decides the EPS attach type whether EPS only or Combined Attach?
We are actually observing high no of combined attach and TAU failures due to “EMM cause: network failure”.
If UE is voice fallback UE it may require combined attach.
If supports VoLTE why it should done a combine attach, no need.
Yes.
Ideally VoLTE users should not try for combined attach but our observing is irrespective of VoLTE capability, all users are trying for combined attach.
