Question: What is the primary purpose of the Automatic Neighbour Cell Relation (ANR) function in a gNB?
Option 1: To automatically detect and remove outdated neighbour cell relations.
Option 2: To relieve the operator from manually managing Neighbour Cell Relations (NCRs).
Option 3: To establish bidirectional Xn links between two gNBs.
Option 4: To manage the global and physical IDs of target cells.
Explanation: The ANR function is designed to automate the management of NCRs, reducing the burden on operators. This involves detecting new neighbours, adding them to the Neighbour Cell Relation Table (NCRT), and removing outdated NCRs. By automating this process, ANR simplifies network management and improves efficiency.
