Abstract
Systems and methods described herein enable premium session retainability for differentiation of services with respect to network function failures. A first network function of a core network obtains a session retention indicator during establishment of a protocol data unit (PDU) session. The first network function calculates a compute footprint for the first network function to support the PDU session and any other premium sessions currently serviced by the first network function. An orchestration device receives the compute footprint and provisions a second network function based on the compute footprint. The first network function and the second network function perform data replication of state information for the PDU session to allow premium sessions to continue with no or minimal interruption in the event of a failover scenario.
