Telecom Rating process

Rating is process to calculate subscriber’s usage charges (Voice/SMS/Other services) as per subscriber’s rate plan and finally loaded into DB for further prospects. The rated CDR further sent to credit monitoring. When the credit amount on the customer’s balance has reached a certain limit, some predefined actions such as granting a discount or sending SMS alert to customer carried out. Rated CDR also further used to analysis of fraud in terms of high usage.

Rating of calls made on below parameters.

A: Time of call (off peak/on peak)

B: Usages volume (call duration/amount of data usage/ number of SMS sent/).

C: Destination (National/ International/Roaming)
