Feature Description

The MME allows to configure the Gateway selection priority when priority is configured as S-GW. MME selects S-GW first, and P-GW will be selected based on the co-location string from the selected S-GW. For the additional PDN, P-GW is selected based on the colocation string from the selected S-GW. When this feature is not configured, by default P-GW is selected first.
