Feature Description

The MME accepts a new format for the operator-identifier. When the configured APN matches with the APN that gets constructed with APN operator identifier (APN-OI), then the corresponding APN profile with the P-GW address is selected. APN-OI-Replacement string from the ULA is in the format of ABCD.XYZ.MNCXXX.MCCYYY.GPRS or ABCD.MNCXXX.MCCYYY.GPRS.

MME selects P-GW based on the APN-OI-Replacement in the ULA message from HSS. MME is configured with ipv6.mnc009.mcc262.gprs/ KT5G.B2B.MNC009.MCC262.GPRS as the operator identifier. If this string matches with the APN-OI in the ULA message from HSS, then the configured P-GW is selected.
