Question: What is the primary purpose of storing Public User Identities as Wildcarded Public User Identities in the Home Subscriber Server (HSS)?
Option 1: To enhance security for a specific group of subscribers by masking their identities.
Option 2: To optimize operation and maintenance for a large number of users handled identically by the network.
Option 3: To facilitate roaming services for subscribers across different networks.
Option 4: To prioritize traffic for premium subscribers sharing the same service profile.
Explanation: Storing Public User Identities as Wildcarded Public User Identities in the HSS is primarily done to streamline the management and operation of the network when dealing with a substantial number of users who are registered together and treated uniformly by the network. This approach simplifies administrative tasks without compromising individual user services.
