Any ideia about this S1 cause: interaction-with-other-procedure?

Not yet.
I also tried and searched alot but didn’t find out any crisp solution for this issue.
Experts here can help if they have any suggestions on HUAWEI network.

Yes exactly, and majority failures are belongs to the Radio end.

You may try by optimizing UL RLC retransmission threshold by increasing it and also you may increase N310 and T310.

It is more about missing neighbours and PCI conflicts.

Right, but above recommendation can also be tried if neighbors and PCI conflict is ok.

After parameters change, Accessibility improved.

MOD GLOBALPROCSWITCH:HOPROCCTRLSWITCH=CsfbFlowFirstSwitch-1;
MOD GLOBALPROCSWITCH:HOERABCONFLPROCESSINGSTRAT=ERAB_FLOW_FIRST;

I think those should run in any network.

Exactly, its improved significantly in RNL failures.
But MME failures try with more sites.
To get more insight and bigger picture.

MME failures decreased also.

What about 4G retention and DCR after had performed those changes?

Hi Experts.

Can anyone help with the solution for that fail?

I need to know the fail reason and solution for that failure S1AP_INITIAL_CONTEXT_SETUP_FAIL cause: Interaction-with-other-procedure(29).

Vendor is Huawei.

It is a normal procedure as per 3GPP, and often occurring due to conflict between HO and CSFB.

There is switch to prefer which one ocurring first, HO or CSFB in Huawei.
