 The packet core instance can provide a RAN with an RFSP Index. The RAN can match the RFSP Index to its local configuration to apply specific radio resource management (RRM) policies, such as cell reselection or frequency layer redirection.
 
+### Multi-Operator Core Network (MOCN)
+
+Multi-operator Core Network (MOCN) aims to maximize resource usage by sharing a RAN between multiple core networks. Azure Private 5G Core supports MOCN, allowing multiple public land mobile networks (PLMNs) to be shared by a gNodeB (for 5G deployments) or eNodeB (for 4G deployments).
+
+In the context of private mobile networks, a single RAN can connect to both a private and a standard macro network, with traffic automatically routed to the appropriate core network based on the PLMN ID.

 ## Flexible integration with Azure private multi-access edge compute (MEC) partners
 
 Each packet core instance is standards-compliant and compatible with several radio access network (RAN) partners in the Azure private MEC ecosystem.
