The Diameter Service’s Determine Network Operator Feature sets the network operator element of the Sentinel selection key for use in the selection of feature execution scripts, mappers and address lists.
This feature is needed for multi-tenancy scenarios. This feature is intended to be used in the direct access case. The feature will set the Network Operator element of the Sentinel selection key based on the value returned by the DetermineNetworkOperator function below.
Determine Network Operator feature uses the 3GPP-IMSI-MCC-MNC of the initial CCR to determine the network operator. It uses a map of (3GPP-IMSI-MCC-MNC → network operator). If no mapping can be found, then a default network operator is returned.
3GPP-IMSI-MCC-MNC : MCC and MNC extracted from the user’s IMSI (first 5 or 6 digits, as applicable from the presented IMSI).

Configuration
IMSI-MCC-MNC to network operator mapping table:
| Parameter | Type | Description |
|---|---|---|
Address |
GT Address |
The ImsiMccMnc address (for example: 00101) |
NetworkOperator |
String |
The Network Operator to set (for example: MVNO1) |
The default is stored in the Sentinel configuration table.
