Question: In GSM networks, when a CBC sends a SET-DRX Request to a BSC, which of the following statements is true regarding the application of new DRX parameters in cells?
Option 1: New DRX parameters are applied immediately across all cells, regardless of their current broadcast message load.
Option 2: The new DRX parameters are only applied to cells that are currently handling high-priority CBS messages.
Option 3: Application of new DRX parameters depends on the existing loading conditions but is effective from the moment of receipt.
Option 4: New DRX parameters will be taken into account starting from the next schedule period in each cell, and are applied to all cells not handling any broadcast message.
Explanation: This is correct because when a BSC receives a SET-DRX Indication, new DRX parameters are considered from the next schedule period in each cell. They are applied to all cells without any broadcast message, ensuring efficient resource management without interrupting ongoing broadcasts.
