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
