Question: In a GERAN (GSM/EDGE Radio Access Network) environment, as per 3GPP Location Services (LCS) specifications, which of the following is NOT a specified locating method?
Option 1: Cell Identity (CI) positioning method
Option 2: Enhanced Observed Time Difference (E-OTD) positioning method
Option 3: Angle Of Arrival (AOA) positioning method
Option 4: Uplink Time Difference of Arrival (UTDOA) positioning method
Explanation: According to GERAN LCS specifications, supported locating methods include cell coverage based positioning, Enhanced Observed Time Difference (E-OTD), A-GNSS based positioning methods, and Uplink Time Difference of Arrival (UTDOA). Angle Of Arrival (AOA) is not among these specified methods.
