Abstract
Apparatus and methods for managing use of radio frequency channels in unlicensed radio frequency bands by a wireless communication device in communication with a cellular wireless network are disclosed. The wireless communication device obtains, from an eNodeB of the wireless network, one or more access network discovery and selection function (ANDSF) policies that include rules for mobility of the wireless communication device and offloading of traffic for the wireless communication device to radio frequency channels in an unlicensed radio frequency band. The wireless communication device determines when at least one radio frequency channel in the unlicensed radio frequency band is available for offloading traffic, for network selection, for network re-selection, or for a supplemental connection via carrier aggregation based on the ANDSF policies, measured interference levels, and/or loading information provided by the eNodeB.
