By default, SGSN management functionality is enabled for console-based access.
Multiple PLMN Support
With this feature, the 2.5G and 3G SGSNs now support more than one PLMN ID per SGSN. Multiple PLMN support
facilitates MS handover from one PLMN to another PLMN.
facilitates MS handover from one PLMN to another PLMN.
Multiple PLMN support also means an operator can 'hire out' their infrastructure to other operators who may wish to use
their own PLMN IDs. As well, multiple PLMN support enables an operator to assign more than one PLMN ID to a cell-
site or an operator can assign each cell-site a single PLMN ID in a multi-cell network (typically, there are no more than
3 or 4 PLMN IDs in a single network).

This feature is enabled by configuring, within a single context, multiple instances of either an IuPS service for a single
3G SGSN service or multiple GPRS services for a 2.G SGSN. Each IuPS service or GPRS service is configured with a
unique PLMN ID. Each of the SGSN and/or GPRS services must use the same MAP, SGTPU and GS services so these
only need to be defined one-time per context.
