Let’s take the sample use case where the law enforcement is tasked with identifying players who are playing the notorious Blue Whale game.įind all end users / telecom subscribers / ISP subscribers in a specific geographic area playing Blue Whale. This makes it easy for law enforcement to identify end users. Now CDR also captures IMEI, Mobile Number (MSISDN ), Cell ID and thus location. The billing can be even done by simply parsing the CDR & calculating call duration, data usage etc. Call Detail Record (CDR) is used by the telecom companies often in the HLR (Home Location Register) suite to handle call duration, features and finally billing.
