1. A method of operating a home network to serve a wireless data service to visiting User Equipment (UEs) affiliated with visited networks and to authorize the wireless data service for home UEs affiliated with the home network and visiting the visited networks, the method comprising:
a network gateway transferring home network communication context to one or more distributed ledgers, receiving visited network communication context from the one or more distributed ledgers, and transferring the visited network communication context to a network controller;
the network controller receiving the visited network communication context from the network gateway and exchanging network authorization data with the visited networks based on the visited network communication context and the home network communication context;
the network controller authorizing the wireless data service for the home UEs and the visiting UEs responsive to the exchange of the network authorization data;
the network controller transferring session signaling to wireless access nodes responsive to the authorization of the wireless data service for the visiting UEs and transferring authorization signaling to the visited networks responsive to the authorization of the wireless data service for the home UEs; and
the wireless access nodes receiving the session signaling from the network controller and responsively delivering the wireless data service to the visiting UEs.
