Abstract
One embodiment is directed to a method comprising receiving and storing a set of cellular network and unlicensed frequency network interworking parameters from a cellular source cell; offloading data traffic from the cellular source cell to an unlicensed frequency network based on the stored set of interworking parameters; receiving a handover command including a second set of cellular network and unlicensed frequency network interworking parameters; checking whether information regarding unlicensed frequency network has been received from a cellular target cell; and if the information regarding unlicensed frequency network has not been received, determining whether to use the second set of cellular network and unlicensed frequency network interworking parameters after the handover.
