Arrangement and method relating to service provisioning control

The present invention relates to an arrangement, in a communication network system supporting communication of packet data. It comprises/has access to mobile subscriber data and comprises means for handling subscriber identity information. It further comprises service level control means (61,62;6) for allocating service level profiles, e.g. QoS profiles, to subscribers. Said services level control means (61,62;6) comprises profile configuration means, for defining network service level profiles (7) and linking subscriber identity information entities to said network service profiles defining the highest allowed service levels at least for a number of different parameters at least for groups of subscribers identified by said subscriber identity information entities. It optionally comprises first validation means (8A) for validating the service level (profiles) requested by subscribers against operator defined subscriber profiles for said subscribers, and at least second validation means (8B) for validating (validated) subscriber profiles against corresponding defined network service profiles for the requesting subscribers as given by the subscriber identity information entities, such that the resource and/or service level profile allocated to a requesting subscriber (11;1) can be controlled.
