Question: In E-UTRAN, what is the primary purpose of the assistance data delivery procedure between the E-SMLC (Evolved Serving Mobile Location Centre) and eNodeB (evolved Node B)?
Option 1: To establish a direct communication link between the UE (User Equipment) and E-SMLC for positioning.
Option 2: To facilitate handover procedures between different eNodeBs in the network.
Option 3: To enable the eNodeB to provide assistance data to the E-SMLC, which is then used for delivering to the UE or calculating positioning estimates at the E-SMLC.
Option 4: To synchronize location-related parameters across all eNodeBs in a given network area.
Explanation: This option correctly identifies the primary purpose of the assistance data delivery procedure. The procedure's main goal is to equip the E-SMLC with necessary assistance data from the eNodeB, which can then be either forwarded to the UE to assist in its positioning calculations or utilized by the E-SMLC itself for estimating the UE's location, crucial for efficient and accurate location services within the E-UTRAN network.
