  • sending, from the control-plane entity to the user-plane entity, an event in accordance with a media gateway control protocol, wherein the event orders the user-plane entity to notify the control-plane entity when the user-plane entity discovers the faulty path;

    sending at least one heartbeat message through the path;

    determining whether one of said at least one heartbeat acknowledgment message has been received through the path; and

    if one of said at least one heartbeat acknowledgment message has not been received, notifying the control-plane entity of the faulty path.
