Abstract: The present disclosure provides a system and method for facilitating tracking area code (TAC) engine to prepare dynamic network polygons based on actual configuration, allocation of TAC to new cell sites, identification of various discrepancies and anomalies in existing planned network, capacity optimization through TAC Division, merge and network polygon edit, and auto work order generation and execution of changes in respective systems, MME Pool and eNB/SCs. Tracking Area Code is a vital parameter for new sites planning and rollout. The method complements network rollout speed with highest level of accuracy of planning and better network perform nave and accuracy. Auto planning engine makes TAC planning zero touch engine with manual review and action through manual edit, audit and work order creation features. Auto planning and configuration help faster rollout, speedy correction and implementation in live network to enhance network performance and user experience.
