Question: In a Voice Group Call Service (VGCS), how are cells within a group call area uniquely identified across the network?
Option 1: By their Cell Global Identity (CGI) alone
Option 2: By a combination of Location Area Code (LAC) and Cell Identity (CI)
Option 3: Solely by the Mobile Country Code (MCC) and Mobile Network Code (MNC)
Option 4: Through dynamic allocation based on available radio resources
Explanation: The correct identification method for cells within a VGCS group call area involves combining the Location Area Code (LAC) with the Cell Identity (CI), ensuring each cell is distinctly recognizable, supporting efficient call management and resource allocation across complex network configurations.
