Abstract
A method is provided in one example embodiment and includes receiving a downstream data packet transported on a backhaul link at a first network element, the downstream data packet is associated with a user equipment; identifying whether a downstream tunnel used to communicate the data packet to the user equipment has become dormant; and communicating an in-band message to a second network element that the downstream tunnel is dormant. In other examples, the method can include dropping the data packet when a network address port translation binding has expired or does not exist. In certain implementations, the method can include identifying the downstream tunnel as dormant when an activity timer has expired, or identifying the downstream tunnel as dormant based on a stale state setting.
