MOCN is one of those great concepts I’d not really come across,
Multi-tenancy on the RAN side of the network, allowing an eNB to broadcast multiple PLMN IDs (MCC/MNC) in the System Information Block (SIB).
It allows site sharing not just on the tower itself, but site sharing on the RAN side, allowing customers of MNO A to see themselves connected to MNO A, and customers from MNO B see themselves as connected to MNO B, but they’re both connected to the same RAN hardware.
Setup in my lab was a breeze; your RAN hardware will probably be different.
In terms of signaling it’s a standard S1AP Setup Request except with multiple broadcast PLMN keys:

Now when I run a manual cell selection on my UE I can see the PLMN 460/11 as well as the Open5gs 00101 PLMN:
What is the maximum number of broadcastPLMN ?
I believe this varies vendor to vendor.
Hi Nick, what type of Radio did you used ? that one has the MOCN list already enabled ? Thanks!
Mi Miguel,
Most radios these days from the big kit vendors support this, I’ve done it on Huawei and Ericsson in production networks.
Cheers,
Nick
