Question: What two essential components comprise the CellGlobalIdEUTRA to uniquely identify a cell in an Evolved Universal Terrestrial Radio Access Network (E-UTRA)?
Option 1: Tracking Area Code (TAC) and Cell Identity (CI)
Option 2: Public Land Mobile Network Identity (PLMN-Identity) and Cell Identity
Option 3: Mobile Country Code (MCC) alone, which inherently includes both
Option 4: Location Area Code (LAC) and Routing Area Code (RAC)
Explanation: In the context of E-UTRA, uniquely identifying a cell requires specifying both the network it belongs to and the cell itself within that network. The Public Land Mobile Network Identity (PLMN-Identity) identifies the network, while the Cell Identity distinguishes the specific cell within that network. This combination ensures global uniqueness.
