Question: What is the implication for the Cell Broadcast Center (CBC) when it receives a RESTART-INDICATION without a Recovery Indication parameter from a Base Station Controller/Radio Network Controller (BSC/RNC)?
Option 1: The CBC assumes no CB-related data were lost for the cells listed and skips re-loading.
Option 2: The CBC initiates an emergency alert to all cells in the affected area.
Option 3: The BSC/RNC is instructed to restart the entire network.
Option 4: The CBC interprets it as if CB-related data were lost for the referenced cells and proceeds to re-load them.
Explanation: If the Recovery Indication parameter is absent in a RESTART-INDICATION, the CBC interprets this as an indication that CB-related data are lost for the referenced cells. Consequently, the CBC will proceed with re-loading the lost data to ensure continuity and integrity of Cell Broadcast Services across the affected cells.
