Question: What is the primary purpose of the GPRS-CSI parameter in the context of Mobile Application Part (MAP) specification?
Option 1: To authenticate User Equipment (UE) for GSM services
Option 2: To indicate support for Extensible Call Barring Information
Option 3: To identify a subscriber with GPRS CAMEL services
Option 4: To manage password attempts for SS-Code services
Explanation: The correct answer, Option 3, accurately reflects the purpose of the GPRS-CSI parameter. It identifies subscribers who have GPRS CAMEL (Customized Applications for Mobile networks Enhanced Logic) services, crucial for telecom networks to manage and provide customized services efficiently. The other options refer to unrelated authentication processes, features not primarily associated with GPRS-CSI, or specific service management aspects not directly linked to the parameter's main purpose.
