Hi Expert, there is case where UE cannot enable to send RRC_UE_CAPABILITY_INFORMATION till session expires then it resulting S1_INITIAL_CONTEXT_SETUP_FAILURE with “interaction-with-other-procedure” and from CN sent “Delete session request” after 7s then NAS EPS Mobility Management Message Type: Attach reject with EMM cause Protocol error, unspecified (111) sent to UE.
I think that “interaction-with-other-procedure” is due to another reason, not due to Ue not send UE_CAP_INFOR.
Could you send a picture of signaling messages?
in common thing yes some of interaction with other procedure corelated like overwrite with HO procedure and something else.
another case but it was solved because some handset only support band 1 and after changed the reselection to band 1 it got resolved. but in this case i check UE supported in current layer so there is no limitation i believed. FYI handset is Hmd Global Oy TA-1165/C1
i guess also this because of handset issue. btw any workaround why this node cannot respond in part of UE-CAP? bear in mind no issue on UL/DL and site under good condition here
In the UE Capability Enquiry message, the enodeb can request specific bands only so the ue capability Information becomes smaller specially in CA combinations
