Question: What is a primary objective of standardizing the Iub parts (User data transport, Signalling, Node B Logical O&M) in the UTRAN Iub Interface Specification?
Option 1: To ensure backward compatibility with 2G networks.
Option 2: To facilitate interoperability between RNCs and Node Bs from different manufacturers.
Option 3: To prioritize the transport of Implementation Specific O&M over standard Iub interface traffic.
Option 4: To mandate a specific Transport Network technology for all UTRAN deployments.
Explanation: Standardizing the Iub parts enables seamless inter-connection and operation between Radio Network Controllers (RNCs) and Node Bs, even when these components are sourced from different vendors. This interoperability is crucial for ensuring flexibility, reducing costs, and promoting innovation in UTRAN deployments. By standardizing these aspects, 3GPP facilitates a more open and competitive market, benefiting both operators and end-users.
