Abstract: Aspects of the subject disclosure may include, for example, a device including a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations of receiving a query for 5G Session Management Functions (SMFs) to handle a connection request, wherein the query includes a slice ID and data network name; determining a list of SMFs that each have a blockchain ID immutably recorded on a blockchain, wherein the blockchain ID is authorized to provide service to the slice ID; and sending, responsive to the query, the list of SMFs. Other embodiments are disclosed.

Abstract: A mobile call processing methodology and concomitant system based on ISDN/CACH-EKTS technology which can broadcast incoming calls to base stations (e.g., 1050) and which uses the ISDN/CACH-EKTS bridging technology to handle base station handoff of an established call. Each mobile user (e.g., 1041, 1042) is assigned a unique EKTS directory number as well as a unique call appearance identifier, which allows for the handling of multiple call appearances of the unique DN on a single base station. For a given mobile communication application, the central office (e.g., 1014) treats the base station as an ISDN/CACH-EKTS terminal.
