Question: What is a characteristic of a Location Area in terms of Mobile Station (MS) location updates?
Option 1: MSs must perform a location update every time they move to a new cell within the Location Area.
Option 2: After an initial location update, MSs can roam within the Location Area without needing subsequent location updates due to location changes.
Option 3: A Location Area always consists of only one cell, requiring a location update for any movement.
Option 4: Location Areas are defined by the coverage of a single MSC, with no further subdivision.
Explanation: This is correct because, as defined in telecom network architecture, a Location Area allows Mobile Stations (MSs) to move freely within its boundaries after an initial location update, without needing additional updates solely due to changing locations within that area, facilitating seamless roaming and efficient use of network resources.
