Question: What is a key requirement for the 5G system in terms of minimizing service interruption when switching a DualSteer device's user data between two 3GPP access networks?
Option 1: The 5G system shall be able to support mechanisms to minimize service interruption, subject to HPLMN policy and network control.
Option 2: The 5G system may only switch the user data of a single service at a time.
Option 3: The 5G system is not required to support mechanisms for minimizing service interruption when switching between two 3GPP access networks.
Option 4: The 5G system shall always prioritize the use of non-3GPP access networks over 3GPP access networks.
Explanation: This question requires an understanding of the key requirements for the 5G system in terms of minimizing service interruption when switching a DualSteer device's user data between two 3GPP access networks. The correct answer, Option 1, highlights the importance of supporting mechanisms to minimize service interruption, subject to HPLMN policy and network control. This is crucial for ensuring seamless connectivity and maintaining service continuity in mobile networks.
