Question: What type of signaling, in addition to radio resource negotiation, is also included over the Iub interface between the Node B and the RNC for dedicated connections between UE (User Equipment) and SRNC (Serving Radio Network Controller)?
Option 1: Mobility Management Signaling
Option 2: Session Management Signaling
Option 3: Logical O&M (Operations and Maintenance) Signaling
Option 4: Packet Data Convergence Protocol (PDCP) Signaling
Explanation: The correct answer is Logical O&M Signaling because, in addition to negotiating radio resources for dedicated UE-SRNC connections and managing broadcast channels, logical Operations and Maintenance signaling between Node B and RNC is also encompassed within this interface, highlighting the importance of O&M in network infrastructure operational efficiency and management.
