Adjusting RAN performance by adapting cell coverage area can help optimize a wireless communications network. RAN topology can be adapted based on analysis of historical performance of base stations. Analysis of the historical performance of base stations can be performed in the core-network of a wireless carrier rather than distributing the analysis to RAN elements. Analysis can be based on receiving historical information relating to key performance indicators such as call failure rate, call success rate, handover attempt count, handover attempt failure count, etc. Further, analysis can include the application of predetermined rules relating to preferential performance of the base stations. This can facilitate ranking neighboring base stations, adding new base stations, deleting base stations, black/white listing base stations, etc., in neighbor relations data structures, such as automatic neighbor relations structures for self-organizing networks, e.g., eNodeBs in LTE networks. |
