Question: Upon successful update of an Individual Member UE Selection Assistance Subscription, what status code(s) may the Network Exposure Function (NEF) respond with to the Application Function (AF), along with the associated data structure (if any)?
Option 1: 200 OK with MemUeSelectAssistSubsc data structure or 204 No Content
Option 2: Only 200 OK with MemUeSelectAssistSubsc data structure
Option 3: Only 204 No Content without any data structure
Option 4: 201 Created with MemUeSelectAssistSubsc data structure
Explanation: Upon a successful update, the NEF has the flexibility to respond in two ways, depending on whether it needs to return the updated subscription details. A 200 OK status code is used when the NEF includes the MemUeSelectAssistSubsc data structure in the response body, providing the AF with the updated details. Conversely, a 204 No Content status code indicates success but without returning any content, implying that the update was successful but no additional information needs to be conveyed back to the AF regarding the subscription’s state. This dual approach accommodates different use cases based on the application’s requirements for post-update feedback.
