Question: What is the primary purpose of a Dedicated Core Network ID (DCN-ID) in a Public Land Mobile Network (PLMN), and what is the range for operator-specific values?
Option 1: To identify a cell tower; Operator-specific values range from 0 to 127.
Option 2: To identify a Dedicated Core Network (DCN); Operator-specific values range from 128 to 65535.
Option 3: To authenticate User Equipment (UE); Operator-specific values range from 1 to 255.
Option 4: To manage Quality of Service (QoS); Operator-specific values range from 256 to 512.
Explanation: In telecom networks, identifying specific components or networks is crucial for efficient operation. A Dedicated Core Network ID (DCN-ID) serves to uniquely identify a Dedicated Core Network within a Public Land Mobile Network (PLMN). Understanding the purpose of such identifiers helps in managing and optimizing network resources. The range of 128 to 65535 being operator-specific for DCN-ID values indicates the flexibility given to operators to customize their network identifications beyond standardized values, which aids in scalability and personalized network management.
