A quality of service, QoS, central controller configured to manage QoS classes in a communication network by use of a QoS class indicator, QCI, structure, wherein each QoS class is identified by a QCI that is arranged according to the QCI structure, the QCI structure comprising: - an identifier of a provider of an industry vertical and/or of a service in the communication network, and - a QoS parameter set for the provider of the industry vertical and/or of the service, wherein the QoS central controller is configured to: - authorize a provider of an industry vertical and/or of a service in the communication network; and - generate a new QoS class by generating at least one new QCI according to the QCI structure and adding the at least one new QCI to a QCI set managed by the QoS central controller; wherein for generating the new QoS class, the QoS central controller is configured to: - receive a new QoS class request of the provider of the industry vertical and/or of the service for generating the new QoS class, wherein the new QoS class request indicates a requested new QoS parameter set, comprising QoS parameters for the new QoS class; and - generate the new QoS class by generating the at least one new QCI comprising an identifier of the provider of the industry vertical and/or of the service, which requests the generation of the new QoS class, and a new QoS parameter set for the provider of the industry vertical and/or of the service, which requests the generation of the new QoS class, wherein the new QoS parameter set is generated according to the requested new QoS parameter set; or wherein for generating the new QoS class, the QoS central controller is configured to: - receive a new QoS class request of the provider of the industry vertical and/or of the service for generating the new QoS class, wherein the new QoS class request indicates a requested new QoS parameter set, comprising QoS parameters for the new QoS class; and - for each sub-network of one or more sub-networks of the communication network, the QoS central controller is configured to: - verify the new QoS class request in view of policies allowed for the provider of the industry vertical and/or of the service in the respective sub-network; and - if the new QoS class request is allowable in view of the policies in the respective sub-network, verify capabilities of the sub-network towards the provider of the industry vertical and/or of the service in the respective sub-network, and generate, for the respective sub-network, a corresponding new QCI for the provider of the industry vertical and/or of the service, which requests the generation of the new QoS class. - an identifier of a provider of an industry vertical and/or of a service in the communication network, and - a QoS parameter set for the provider of the industry vertical and/or of the service, - authorize a provider of an industry vertical and/or of a service in the communication network; and - generate a new QoS class by generating at least one new QCI according to the QCI structure and adding the at least one new QCI to a QCI set managed by the QoS central controller; - receive a new QoS class request of the provider of the industry vertical and/or of the service for generating the new QoS class, wherein the new QoS class request indicates a requested new QoS parameter set, comprising QoS parameters for the new QoS class; and - generate the new QoS class by generating the at least one new QCI comprising an identifier of the provider of the industry vertical and/or of the service, which requests the generation of the new QoS class, and a new QoS parameter set for the provider of the industry vertical and/or of the service, which requests the generation of the new QoS class, wherein the new QoS parameter set is generated according to the requested new QoS parameter set; - receive a new QoS class request of the provider of the industry vertical and/or of the service for generating the new QoS class, wherein the new QoS class request indicates a requested new QoS parameter set, comprising QoS parameters for the new QoS class; and - for each sub-network of one or more sub-networks of the communication network, the QoS central controller is configured to: - verify the new QoS class request in view of policies allowed for the provider of the industry vertical and/or of the service in the respective sub-network; and - if the new QoS class request is allowable in view of the policies in the respective sub-network, verify capabilities of the sub-network towards the provider of the industry vertical and/or of the service in the respective sub-network, and generate, for the respective sub-network, a corresponding new QCI for the provider of the industry vertical and/or of the service, which requests the generation of the new QoS class. - verify the new QoS class request in view of policies allowed for the provider of the industry vertical and/or of the service in the respective sub-network; and - if the new QoS class request is allowable in view of the policies in the respective sub-network, verify capabilities of the sub-network towards the provider of the industry vertical and/or of the service in the respective sub-network, and generate, for the respective sub-network, a corresponding new QCI for the provider of the industry vertical and/or of the service, which requests the generation of the new QoS class.
