Question: In a shared telecommunications network, what is a key requirement for service provision as per 3GPP principles?
Option 1: Core network operators must offer identical service portfolios to maintain consistency across the shared infrastructure.
Option 2: The existence of network sharing should not restrict the provision of services and service capabilities, allowing for differentiation between core network operators.
Option 3: Shared networks can only provide a standardized set of services, with no room for customization by individual core network operators.
Option 4: Service capabilities in shared networks are solely controlled by the infrastructure provider, not the core network operators.
Explanation: This answer reflects the principle that network sharing should not limit service innovation or differentiation. By allowing each core network operator to control access to service capabilities based on user subscription, the shared network model supports competitive service offerings, enhancing user choice and experience. This aligns with the telecom domain’s focus on flexible, customer-centric service provision.
