A communication technique for providing a mobile gateway in a radio node (such as an eNodeB) in a local wireless network that is associated with a venue is described. During the communication technique, the radio node may provide, via the mobile gateway, cellular-telephone-network services. In particular, the mobile gateway may implement functions including: providing, when an electronic device attaches to the local wireless network, an Internet Protocol (IP) address to the electronic device based on a media access control (MAC) address for the electronic device, which is, in part, provided by a mobile management entity (MME) in a cellular-telephone network; triggering, via a supported interface, paging to the electronic device when the electronic device is in idle in the local wireless network; transmitting uplink data and receiving downlink data via a cellular-telephone communication protocol (such as Long Term Evolution or LTE); and/or electronic-device mobility in the local wireless network.
