Question: In a 3GPP network, when an I-WLAN Equivalent HPLMN Presentation Indication (EFWEHPLMNPI) file is present and its value is set to '01', what does this indicate for the Mobile Equipment (ME) during I-WLAN selection procedures?
Option 1: The ME should display all available EHPLMNs in alphabetical order.
Option 2: The ME has no preference for displaying EHPLMNs, and this setting is ignored.
Option 3: The ME should only display the highest-priority available EHPLMN.
Option 4: The ME will not display any EHPLMNs until further user input.
Explanation: According to the I-WLAN EHPLMN Presentation Indication settings, a value of '01' specifically instructs the Mobile Equipment (ME) to display only the highest-priority available Equivalent HPLMN (EHPLMN) during the I-WLAN selection process. This ensures that the user is presented with the most preferred network option first, streamlining the connection process.
