Question: What is a primary benefit of monitoring per-QCI (QoS Class Identifier) counters for radio bearer QoS in a cellular network, such as for QCI 1 used exclusively for VoIP?
Option 1: To optimize network security protocols for different service types.
Option 2: To directly determine the loading of specific service types (e.g., conversational speech) within the cell.
Option 3: To prioritize handover decisions based on QoS requirements.
Option 4: To adjust billing rates dynamically based on throughput.
Explanation: Monitoring per-QCI counters allows operators to understand how different services (identified by their QCI, such as QCI 1 for VoIP) are utilizing network resources. This enables targeted optimization and capacity planning for specific types of traffic, ensuring the network can adequately support the desired quality of service for each service type. In the case of QCI 1 for VoIP, it helps in directly measuring the load due to conversational speech, facilitating more precise network management decisions.
