Secondary or splice-specific access control in a wireless communication network

A data management network node configured for use in a wireless communication network, the data management network node comprising:

• communication circuitry;
• and
• processing circuitry configured to:
• store subscription data for a wireless device;
• receive, from network equipment, a request that requests subscription data for the wireless device;
• and
• responsive to the request, transmit to the network equipment a response that includes at least some of the stored subscription data, wherein if the subscription data included in the response indicates the wireless device is subscribed to use a certain data network or network slice that is subject to secondary or slice-specific access control, the subscription data included in the response includes at least one generic subscription identifier for the wireless device, wherein a generic subscription identifier generically addresses a subscription to the wireless communication network in different data networks outside the wireless communication network, wherein the response includes or does not include information which identifies the certain data network or network slice depending respectively on whether or not the stored subscription data includes a generic subscription identifier for the wireless device.
