Question: In a 5G network, particularly for use cases like uRLLC (Ultra-Reliable Low Latency Communications), what is a primary reason for defining and measuring end-to-end latency from a network operator's perspective?
Option 1: To optimize network resource allocation for enhanced mobile broadband (eMBB) services.
Option 2: To evaluate the effectiveness of Massive Machine-Type Communications (mMTC) deployments.
Option 3: To ensure compliance with regulatory requirements on data privacy.
Option 4: To guarantee the network performance as promised to the customer, ensuring their service requirements are met.
Explanation: In the context of 5G networks, especially for latency-sensitive applications like uRLLC, measuring end-to-end latency is crucial. This measurement ensures that the network operator can verify whether the promised network performance (in terms of latency) is indeed delivered to the customer, thereby meeting their service requirements. This is vital for maintaining service quality and customer satisfaction, particularly in scenarios where low latency is a critical factor.
