Abstract
A method of handing off between a cellular network and a Wi-Fi network is disclosed. A cellular base station of the cellular network is caused to collect information related to the cellular network. A Wi-Fi access point of the Wi-Fi network is caused to collect information related to the Wi-Fi network, wherein the cellular base station and the Wi-Fi access point are co-located. The information related to the cellular network and the information related to the Wi-Fi network are used collectively for determining whether to handoff traffic of a user equipment from a cellular air interface of the cellular network to a Wi-Fi air interface of the Wi-Fi network, or vice versa.
