be obtained from the records that could be used in capacity planning rather than billing. Also mediation systems can be used to execute commands like provisioning tasks. 13. Network optimization: The main aim of network optimization solution is to improve the network performance and ensure effective utilization of resources. Optimization would involve changes in operations modeling. This is done to ensure that the service and network performance achieves the ser- vice level parameters shared with the customer. Optimization of energy usage is another key factor looked into by many telecom companies. The green initiatives in companies have added stress to optimize energy usage. Energy- efficient and sustainable communication can be achieved through optimal network design, site optimization, and the right choice of energy sources. Maximizing resource utilization and implementing scalable solutions to meet the capacity needs of Telco is also an activity under optimization. By optimizing the network, operators can get the most out of their existing investment. Optimizing network performance ensures capacity being used in the most profitable way. Efficient use of energy will help in securing the supply. 14. Data integrity management: When multiple OSS solution interoperates there can be inconsistencies in data that can lead to inaccurate computations and reports. Data integrity deals with insuring that data spread across OSS is consistent and accurate. With real-time service and network provisioning, integrity of data is a key concern. There are applications that handle end-to- end data integrity across solutions and data correction in specific modules like inventory reconciliation for inventory management based on resource discovery. Management Applications Data integrity management application does integrity checks to fix revenue leakage and reduce access cost. In some cases, a database cleanup is also performed as part of data integrity management. These applications can improve tracking of assets and reduce the num
