Question: When dual connectivity is used for redundant transmission in a 5G network, what should be ensured by the network (UDM and/or SMF) regarding the UP security policy settings for all redundant PDU sessions?
Option 1: The UP security policy settings may differ between the first and redundant PDU sessions.
Option 2: The UP security policy settings should have different encryption settings but the same integrity protection settings.
Option 3: The UP security policy settings should be based on the UE's capabilities.
Option 4: All redundant PDU sessions should have the same UP security policy setting.
Explanation: According to the security policy aspects for dual connectivity in a 5G network, the network (UDM and/or SMF) shall ensure that all redundant PDU sessions have the same UP security policy setting. This ensures consistent security measures are applied across all redundant transmissions, maintaining the integrity and confidentiality of the data being transmitted.
