Question: What is the primary purpose of the Global Cable Identifier (GCI) in the context of Wireless and Wireline Convergence Access Support for the 5G System (5GS)?
Option 1: To provide a globally unique identifier for the line connecting the CRG to the network, facilitating user location information on cable access.
Option 2: Exclusively to build a SUCI for FN CRG types without any broader application in user identification or location services.
Option 3: Solely for administrative purposes, managed by the W-AGF operator, without direct impact on user or device identification.
Option 4: To encode HFC Node ID and HFC_Identifier in a fixed-length format for all CRG types.
Explanation: The Global Cable Identifier (GCI) defines a globally unique identifier for the line connecting the Customer Premises Equipment via a Cable Residential Gateway to the network, crucial for identifying the connection point and facilitating User Location Information on Cable access, making it a broader scope than just building a SUCI or other mentioned purposes.
