A method is disclosed for authorization of resources clustered into one or more resource groups, each resource group comprising functionally interdependent resources.
The method includes receiving an authorization request signal indicative of a first resource for authorization, wherein the first resource is comprised in a first resource group, determining—for each mandatory resource of the first resource group—whether the resource is authorized, and transmitting an authorization response signal. The authorization response signal is indicative of successful authorization of the first resource when all mandatory resources of the first group are determined as authorized. Further, the authorization response signal is indicative of unsuccessful authorization of the first resource when at least one mandatory resource of the first group is determined as unauthorized.
Corresponding apparatus, authorization server, network node and computer program product are also disclosed.
