Abstract: An example method is provided in one example embodiment and may include receiving a session request for a user equipment (UE) at a node, wherein the session request includes a timestamp for the UE and a retry count; determining if the session request is a stray session request; and maintaining session information for an existing session for the UE at the node if the session request is a stray session request. The method can include identifying the received session request as a stray request if the timestamp received in the request is less than a timestamp stored for an existing session for the UE. The method can also include identifying the received request as a stray request if the timestamp received is equal to the timestamp stored for the existing session and if the retry count received is less than or equal to a retry count stored for the session.

Abstract: The present disclosure is directed at systems, methods and media for providing bearer call-back services for bearers that have been rejected or pre-empted by a network apparatus in a core network. In some embodiments, if a network apparatus enters a state in which it becomes necessary to reject or pre-empt a bearer associated with a user equipment (UE) (e.g., due to load conditions in a radio access network, the core network, or an application server), the network apparatus can send to the UE a call-back message when the network apparatus exits the state that precipitated the bearer rejection or pre-emption. By sending a call-back message, the network apparatus can save the UE from multiple unsuccessful attempts to establish a bearer, or from waiting an unnecessarily long time before establishing a bearer.
