No

Prerequisite Features

None

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.

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).
— From 3gpp TS 32.299
