Question: What is the impact of Service Continuity (SC) on the security requirements for the Circuit Switched (CS) Domain, as related to the existing 3G security architecture?
Option 1: SC introduces additional stringent security requirements for the CS Domain, beyond those specified in the 3G security architecture.
Option 2: SC aligns with and reinforces the existing security requirements for the CS Domain, as outlined in the 3G security architecture, without additions.
Option 3: SC temporarily relaxes some security measures in the CS Domain to facilitate seamless service continuity, deviating from the standard 3G security protocols.
Option 4: SC is exempt from adhering to the security standards defined for the CS Domain within the 3G security architecture framework.
Explanation: Service Continuity (SC) does not impose new or additional security requirements on the Circuit Switched (CS) Domain beyond what is already mandated. This ensures consistency and alignment with established security protocols, reinforcing the existing security framework without introducing deviations or enhancements specifically for SC in the CS Domain.
