Question: Which of the following charging information is NOT collected by the PLMN serving the LCS Client for Location Services (LCS) as per 3GPP standards?
Option 1: Type and identity of the LCS Client
Option 2: Cell ID of the target UE's serving cell
Option 3: Results of positioning (e.g., success/failure, method used if known)
Option 4: Identity of the visited PLMN
Explanation: The correct answer is Option 2 because 'Cell ID of the target UE's serving cell' is not among the charging information collected by the PLMN serving the LCS Client. In contrast, all other options are explicitly mentioned as required charging information.
