5 Charging Efficiency
This chapter focuses on the charging efficiency of an Oracle Communications Billing and Revenue Management (BRM) 15.0.1 cloud native system, specifically its ability to handle transaction processing while maintaining optimal resource utilization.
Topics in this document:
Scenario: Voice/Data/SMS Charging Efficiency (19,700 Transactions)
This scenario evaluates the charging efficiency of a BRM 15.0.1 cloud native system by simulating a high volume of transactions. The system’s performance is analyzed using Throughput Efficiency Indexes, which consider the transaction processing speed and CPU usage.
