Question: In a Cell Broadcast Service (CBS) scenario, as per 3GPP standards, what determines the inclusion of the Radio-Resource-Loading-List in a STATUS-LOAD-QUERY Response/Confirm sent by the BSC/RNC?
Option 1: The presence of cells with DRX (Discontinuous Reception) capability.
Option 2: The success or failure of the requested operation in at least one cell indicated in the related Request/Indication.
Option 3: The type of CBS message being broadcast (e.g., emergency alerts vs. commercial messages).
Option 4: The overall network load at the time of the query.
Explanation: According to the 3GPP standards for CBS, the Radio-Resource-Loading-List is included in the STATUS-LOAD-QUERY Response/Confirm if at least one cell successfully performed the requested operation. This list provides insight into the CBCH (Cell Broadcast Channel) or UTRAN Radio Resource loading for each successful cell. If all cells fail the operation, this list is not present. Thus, the determining factor is the outcome of the requested operation in the cells listed in the initial query.
