Abstract

A method and devices for integrating a cellular radio network with a WiFi network are disclosed. According to one aspect, a method includes selecting, at a base station having a cellular radio subsystem and a WiFi radio subsystem, at least one of a cellular radio network carrier and a WiFi carrier to carry at least one data flow from the base station to a user equipment. The method further includes transmitting, from the base station to a user equipment, a control signal to cause the user equipment to select at least one of a cellular radio subsystem of the user equipment and a WiFi radio subsystem of the user equipment to receive the selected at least one of the cellular radio network carrier and the WiFi carrier. Data from the at least one data flow is transmitted on the at least one selected carrier.
