Abstract: A method is provided in one example embodiment and may include sharing an access key from a control-plane serving gateway (SGW-C) to a plurality of user-plane serving gateways (SGW-Us); allocating a plurality of Fully Qualified Tunnel Endpoint Identifiers (FQTEIDs) associated with a user equipment (UE) session; generating an access token for the UE session based, at least in part, on the access key and the plurality of FQTEIDs; and appending the access token to user-plane packets for the UE session. The method can further include receiving a data packet for the UE session by a particular SGW-U, wherein the uplink packet is appended with the access token for the UE session; determining FQTEIDs associated with the UAT; and routing the uplink packet from the particular SGW-U based on the FQTEIDs.
