GSM

The NCIM database models GSM using several database tables.

The following UML diagram shows how NCIM models GSM.

Note: In addition to the standard relationships between entities shown in the core schema diagram, the GSM schema diagram models extra relationships between RAN entities. These RAN entity relationships have been added to make it easier to process RAN data. For example, the dependency relationship between ranBaseStation and ranBaseStationController was added to enable a single query to retrieve all RAN base stations managed by a given RAN base station controller.
