operating a first DHCP server in the second network to receive a first IP address allocation request from a first communications device; and
operating the first DHCP server in the second network to assign a first IP address to the first communications device;
receiving, from the first communications device at the network access point in the second network, a registration request signal;
operating a session management function (SMF) in the second network to communicate at least some authentication or authorization information, sent by the first communications device to the network access point in the second network, to a security entity in a first network;
receiving at the SMF in the second network an authentication response from the security entity in the first network; and
