Question: What is a key requirement for the 5G system in terms of supporting multiple access technologies?
Option 1: The 5G system will only support one type of 3GPP access technology at a time.
Option 2: Interoperability among various access technologies, including 3GPP and non-3GPP, is imperative for the 5G system.
Option 3: The 5G system will prioritize 3GPP access technologies over non-3GPP access technologies for all services.
Option 4: The 5G system will only support a single access technology per UE.
Explanation: Interoperability among various access technologies is crucial for the 5G system to ensure seamless communication and efficient resource utilization. This requirement enables the 5G system to select the most suitable access technology for a service, potentially allowing multiple access technologies to be used simultaneously for one or more services active on a UE (User Equipment).
