Abstract:
1. An apparatus comprising: at least one processor; and at least one memory including computer program code, wherein the at least one processor, the at least one memory, and the computer program code are configured to cause the apparatus to at least: receive, at a bootstrapping server function, a request for security key related policy information for a user equipment device, wherein the request is sent from a visited network, wherein the apparatus is connected to a home network, and wherein the user equipment device is registered to the home network and is seeking to access a service at a service providing node of the visited network; send, from the bootstrapping server function, a service authorization information request including a user security settings package for the user equipment device, wherein the service authorization information request indicates that authorization policy information for the user equipment device be included in the user security settings package; receive, at the bootstrapping server function, from a policy decisioning server, in response to the service authorization information request, a service authorization information answer comprising a modified user security settings package including the authorization policy information for the user equipment device, wherein the policy decisioning server is configured to implement a home access network discovery and selection function; determine whether the received modified user security settings package includes a service specific authorization flag indicating the modified user security settings package has to be forwarded for processing to the policy decisioning server for the service to obtain authorization policy information; generate, at the bootstrapping server function, the requested security key related policy information based on at least the modified user security settings package; and send, from the bootstrapping server function, the requested security key related policy information to the service at the service providing node.
