Question: What information may be included in a DCSF (Data Communication Service Function) profile, in addition to NF type=DCSF, to facilitate user identity management?
Option 1: UE IP Address Ranges
Option 2: IMPU (IP Multimedia Public Identity) ranges for calling and called identities of users
Option 3: APN (Access Point Name) configurations for data services
Option 4: QoS (Quality of Service) profiles for prioritized communications
Explanation: Including IMPU ranges in a DCSF profile is crucial for managing calling and called identities of users served by the DCSF. This facilitates efficient identity management and routing, ensuring proper handling of multimedia communications. The other options are not directly related to the content typically included in a DCSF profile for user identity purposes.
