Question: In a UICC-enabled Mobile Equipment (ME), how does the device determine which Cell Broadcast (CB) messages to display based on language preference?
Option 1: By matching the CB message's Data Coding Scheme against a list of preferred languages stored in the EFDIR file.
Option 2: Through direct comparison of the CB message's language code with the device's default language setting.
Option 3: By comparing the CB message's language, as indicated by its Data Coding Scheme (translated to ISO 639 coding if necessary), against entries in either the EFPL or EFLI files.
Option 4: Based on the Cell Broadcast Message Identifier capability, which automatically filters messages without considering stored language preferences.
Explanation: The ME selects CB messages for display by matching their language (as defined by the Data Coding Scheme and potentially translated to ISO 639 coding) against preferred languages listed in either the EFPL or EFLI files, ensuring users receive messages in their preferred language(s).
