Question: What is the primary effect on cells within a BSC/RNC when a Cell Broadcast Centre (CBC) sends a RESET Request to those cells?
Option 1: The cells transition into a standby mode, preserving all previous Cell Broadcast (CB) message data.
Option 2: The cells enter an operational state, ready to transmit new CB messages immediately.
Option 3: The cells' CB operational state is queried by the BSC/RNC, prompting a status report back to the CBC.
Option 4: The indicated cells reset to an idle state (equivalent to a 'power on' initial state), losing all prior CB message information.
Explanation: This is correct because when a BSC/RNC receives a RESET Request from the CBC, the targeted cells revert to an idle state, akin to their status after a power cycle. This reset results in the loss of all previously stored Cell Broadcast message data within those cells, emphasizing a complete restart of CB operations for the affected cells.
