An example method is provided in one example embodiment and may include determining that a user equipment (UE) is approximately stationary for a threshold period of time within a particular geographic area based, at least in part, on a radio access network (RAN) node to which the UE is attached; notifying the UE that the UE has been associated with the particular geographic area; and transitioning the UE into an idle mode from an active mode, wherein the transitioning is performed without notifying a core network that the UE has transitioned to the idle mode. Determining that the UE is approximately stationary can include monitoring mobility signaling from the UE and comparing an amount of time that the UE has been attached to the RAN node with a threshold period of time. The core network can be notified when the UE moves out of the particular geographic area.
