Device and method for ue registration assisted by analytics to support intra and inter network slice load balancing

A system for mobile network, comprising

• a Network and Data Analytics Function (NWDAF) for generating feedback for supporting a mobile network configuration or change, the NWDAF comprising:
• a processor;
• and
• a non-transitory computer-readable storage medium coupled to the processor and storing processor-executable instructions that, when executed by the processor, facilitate carrying out a method comprising:
• obtaining a support request of a device for performing the mobile network configuration or change, wherein the support request specifies a specific feedback type and target information, and wherein:
• the mobile network configuration or change includes a registration of user equipment (UE) to a network slice (NS) or network slice instance (NSI), and/or
• the target information is information about at least one NS or NSI capable of supporting a type of service or application of the UE;
• and
• determining specific feedback about the target information in response to the support request,
• wherein the specific feedback includes a set of values of the target information that are ranked based on at least one organization parameter in the specific feedback for the set of values.
