Question: In 5G Network Resource Model (NRM), how can a range of IMSIs (International Mobile Subscriber Identities) be represented for subscriber identity management?
Option 1: Solely through Geographic Information System (GIS) mapping to associate subscribers with specific locations.
Option 2: Exclusively by utilizing a single, unique identifier per subscriber without any range or pattern matching.
Option 3: Either by specifying a numeric range of IMSIs or by employing regular-expression matching for more complex patterns.
Option 4: Only through the use of IP address blocks to indirectly manage subscriber identities.
Explanation: In the context of managing and orchestrating 5G network resources, efficiently representing ranges of subscriber identities (IMSI) is crucial. Option 3 correctly identifies that this can be achieved in two flexible ways: by defining a numeric range to cover sequential IMSIs or by using regular-expression matching for more nuanced, non-sequential patterns. This approach supports scalable and versatile management of subscriber identities within the network.
