Question: In a scenario where both Service n°86 and Service n°90 are 'available', and a terminal reads the selected CSG ID, how does the Mobile Equipment (ME) determine the CSG Type to display if associations exist in both EFACSGL and EFOCSGL?
Option 1: The ME always prioritizes the CSG Type from EFACSGL for both services.
Option 2: For Service n°86, the ME uses EFACSGL, but for Service n°90, it only considers EFOCSGT without precedence rules.
Option 3: The determination is based solely on the last updated file between EFACSGL and EFOCSGL, regardless of service.
Option 4: For Service n°86, the ME uses EFACSGL, while for Service n°90, it prioritizes the Operator CSG Type from EFOCSGL over any in EFACSGL.
Explanation: This answer reflects the specified behavior for each service: Service n°86 relies on EFACSGL for CSG Type, while Service n°90 prioritizes the Operator CSG Type from EFOCSGL over any association in EFACSGL, crucial for managing different services' requirements in telecom networks concerning Closed Subscriber Group (CSG) configurations and user experience.
