Question: In a 5G system, how many state machines are used in the UE and AMF to handle connection states over different types of access?
Option 1: One state machine for both 3GPP and non-3GPP access
Option 2: Two separate state machines, one for 3GPP access and another for non-3GPP access
Option 3: Three state machines, one for each type of access (3GPP, non-3GPP, and a third for both)
Option 4: Four state machines, two for 3GPP access and two for non-3GPP access
Explanation: In the context of 5G systems, separate state machines are used to handle connection states over different types of access. This is necessary because 3GPP access (e.g., LTE) and non-3GPP access (e.g., Wi-Fi) have distinct requirements and procedures for managing connections. Using two separate state machines allows the UE and AMF to manage these differences effectively, ensuring seamless connectivity and security across various access types.
