Question: In a Mobile Network, when is the 'Extension-3 QoS-Subscribed' parameter used in relation to uplink bit rates?
Option 1: When the maximum/guaranteed bit rate for uplink exceeds 8640 kbps.
Option 2: When the average bit rate for downlink is below 100 kbps.
Option 3: During handover procedures from 4G to 5G networks.
Option 4: For all QoS subscriptions in LTE networks by default.
Explanation: The 'Extension-3 QoS-Subscribed' parameter is specifically utilized to provide additional QoS information beyond what's offered by the standard Extension QoS-Subscribed parameter, particularly in scenarios where the uplink's maximum or guaranteed bit rate surpasses 8640 kbps, highlighting its role in managing high-bandwidth uplink communications efficiently.
