Question: What is the primary purpose of periodically broadcasting the Fixed Part Beacon Identity (FPBI) on the BCH logical channel in a Cellular Telecommunication System (CTS)?
Option 1: To establish a dedicated connection for incoming calls to CTS-MSs.
Option 2: To enable location updates for roaming CTS-MSs across different CTS-FPs.
Option 3: To synchronize time zones between the CTS-FP and enrolled CTS-MSs.
Option 4: To allow enrolled CTS-MSs to recognize and validate the identity of their serving CTS-FP.
Explanation: Broadcasting the FPBI enables enrolled CTS Mobile Stations (CTS-MSs) to identify and authenticate the Fixed Part (FP) of the Cellular Telecommunication System (CTS) they are connected to, ensuring communication with the expected base station for security and proper network functioning.
