We can use stage 1 to establish 5G corenetwork and can successfully connect enb with LTE,
but for ENDC(example 3a_n78a) mode we cannot connect N78a, only connect successfully to 3a(bands)
does stage 1-free5gc support ENDC ? if it is true , how to config it
Hi,
Stage 1 is no longer supported now.
We have some ENDC patch previously but it is only for business plan usage.
other stage 2 / 3 only for SA mode ?
and if we need NSA , we need to be a member of which’s level ?
NSA of NGC (5GC) need eLTE. We haven’t survey to this parted but we believe that eLTE will remain using NGAP as protocol and no need to have big change on core network.
Reference to NSA Option 4, 5, and 7.
If there is any 3GPP TS spec. studying on it. Please let us know and we can check it out!
how about option3/a/x ? i can use stage 1 to finish option3/a/x ?
A UE is connected to one eNB that acts as a MN and one en-gNB that acts as a SN
We have once working on option 3 for BP on stage 1.
But this is for BP so we may not open source and we’re not maintaining stage 1 now.
If you are interesting for it, you may try to email us to discuss about it.
I have the same question about the stage-1 for NSA EN-DC support under option 3a? Especially, openairinterface has completed the NSA EN-DC demo.
From my experiments, free5GC-stage-1 does not response well to “E-RAB Modification Indication”, the error information is attached.
If you can give more information, that will be very helpful.
Thanks
Hi,
Sorry about that we are not maintaining stage 1 now. And for stage 1 open source, it do not support ENDC feature.
