  • Publication number: 20210092589
    Abstract: Methods are disclosed for provisioning and/or controlling operator profiles in terminals, each having an integrated circuit card identified by an integrated circuit card identifier. A discovery server is configured with an authorization table including associations of integrated circuit card identifier, service provider identifier, and operator identifier(s). The discovery server receives, from a data preparation node, an event registration request comprising a number of elements. The discovery server determines whether the event is authorized. If so, the event is registered. This later enables a terminal to seek to retrieve the event, to contact the data preparation node, and to eventually perform the profile operation. Terminals, network nodes, and computer programs for use in the above method are also disclosed. Some embodiments enable the network-initiated provisioning and/or controlling of operator profiles in machine-to-machine devices.
