摘要

A wireless communication unit (302, 405, 505, 605) is capable of communicating with a plurality of communication networks in a cellular communication system, where the plurality of communication networks employ a respective plurality of radio access technologies. The wireless communication unit (302, 405, 505, 605) comprises a receiver for receiving a message from a network device in the cellular communication system; and signal processing logic, operably coupled to the receiver, for determining from the received message a hierarchical policy of network information that applies to the plurality of radio access technologies.
