  • System and method for handling stray session requests in a network environment
    Patent number: 9936438
    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.
