With the MOCN configuration, the SGSN supports the following scenarios: 
  MOCN with non-supporting UE 
  MOCN with supporting UE 
 
Implementation 
To facilitate network sharing, the SGSN implements the following key features: 
  Multiple virtual SGSN services in a single physical node. 
  Sharing operators can implement independent policies, such as roaming agreements. 
  Equivalent PLMN configuration. 
  RNC identity configuration allows RNC-ID + MCC-MNC instead of just RNC-ID. 
Configuration for network sharing is accomplished by defining: 
  NRI in the SGSN service configuration mode 
  PLMN IDs and RNC IDs in the IuPS configuration mode 
  IMSI ranges in the Operator Policy configuration mode
