A network node in a communication network provides Automated Neighboring Relation (ANR) data to User Equipments (UEs). The network node collects information of ongoing end-to-end traffic sessions from other network nodes in the communication network, and determines service characteristics of Radio Base Stations (RBSs) based on the collected information. For each RBS, the network node creates an ANR record indicating the determined service characteristics of neighboring RBSs. The network node then transmits the ANR record to each RBS to cause the RBS to propagate the ANR record to attached UEs.
