MOCN-type Network Sharing
With the MOCN configuration, the SGSN supports the following scenarios:
MOCN with non-supporting UE
MOCN with supporting UE
Important:
The MOCN network sharing functionality now requires a separate feature license for both 2G and
3G scenarios. Contact your Cisco representative for licensing information.
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
Equivalent PLMN IDs and configured in the Call-Control Profile configuration mode.
IMSI ranges are defined in the SGSN-Global configuration mode
The Call-Control Profile and IMSI ranges are associated in the configuration mode.
