Question: In Network Operation Mode II, when a BSC receives a CS paging request from the CN domain and determines the MS is engaged with the PS domain, how will the CS paging be performed for that MS?
Option 1: On a packet data channel for the MS in question
Option 2: On a CS dedicated channel for the MS in question
Option 3: On the CCCH (Common Control Channel) paging channel
Option 4: Not possible, as BSS coordination is not applicable in this scenario
Explanation: In Network Operation Mode II, when the BSC finds that an MS is engaged with the PS domain upon receiving a CS paging request from the CN domain, it utilizes a packet data channel for the CS paging to reach the MS efficiently. This approach leverages the existing connection in the PS domain to deliver the CS page, highlighting the coordination between domains at the BSS level to optimize resource usage and ensure timely delivery of pages across different network domains (CS - Circuit Switched and PS - Packet Switched).
