AI Technical Summary

Technical Problem

There is an underspecification of how to perform a network slice availability check, which is crucial for ensuring that the requested slice is supported for a user equipment (UE) in a specific location before providing performance boost upsell offers.

Method used

The proposed solution involves a method where a first network node sends a message to a network exposure node to request or check the availability status of a network slice, which may include subscribing to notifications for updates on slice availability. This method allows for determining the availability of network slices based on information about available or allowed slices.

Benefits of technology

This solution enables third-party applications and UE to determine whether a candidate network slice is deployed and available in a specific area, allowing for better decision-making on service processing and resource requests, thereby enhancing user experience and avoiding accounting misalignments.
