+         *
+         * For example, QNS can suggest frameworks to setup IMS on IWLAN by specifying

+         * {@link AccessNetworkType#IWLAN}.

+         * {{@link AccessNetworkType#EUTRAN}, {@link AccessNetworkType#IWLAN}}. Frameworks will then
+         * first attempt to setup data on LTE network. If the device moves from LTE to UMTS, then
+         * frameworks can perform handover the data network to the second preferred access network
+         * if available.
+         *
+         * If the {@code qualifiedNetworkTypes} list is empty, it means QNS has no suggestion to the
+         * frameworks, and frameworks will decide the transport to setup the data network.

-         * is a {@link AccessNetworkType}. An empty list indicates no networks are qualified
