wherein the network device comprises one or more memories storing instructions and one or more processors capable of executing the instructions causing the network device to:
update the first function, wherein a new communication scheme is added to the updated first function to transmit a first request for receiving a registration code for the network device;
in response to the first function having been updated, start to transmit the first request to the device management system by using the new communication scheme of the updated first function; and
wherein the device management system transmits, as a response to the first request, the registration code to the network device in a case where management information of the network device indicates that a license for the second service has been issued to the network device,
wherein the instructions further cause the network device to:
in response to the registration code having been received from the device management system, transmit information for device authentication of the network device to the device management system;
receive an authorization token using for a verification of the network device as a communication source from the device management system;
