Abstract:
A method is provided in one example embodiment and may include maintaining, by a Diameter Routing Agent (DRA), an availability status for a plurality of network elements; receiving a request associated with a user equipment (UE) session, wherein a first network element of the plurality of network elements is serving the UE session; determining that the first network element serving the UE session is unavailable; and re-establishing the UE session at a second network element of the plurality of network elements that is available, wherein the re-establishing is performed without terminating the UE session.
