A system described herein may provide a technique for a selection of an Interworking Function (“IWF”) that facilitates an interworking between a licensed wireless network and another wireless network, such as an unlicensed wireless network, based on a geographical location of a User Equipment (“UE”) that is connected to the licensed wireless network and the other wireless network. The IWF may be selected from a set of candidate IWFs based on respective locations of the candidate IWFs and the UE and/or a wireless access point associated with the other wireless network. The IWF may communicate with the UE, via the other wireless network, using one or more tunnels. The IWF may identify control plane and user plane traffic received via the tunnel(s), and may forward such communications to appropriate network devices of the licensed wireless network.
