Call Detail Record (CDR) GSM Mobile Telephone Call

Call Detail Record (CDR) GSM Mobile Telephone Call

.

For every mobile telephone call there should be a corresponding Call Detail Record (CDR). It can contain information that the mobile network operator uses for subscriber identification, call charging, services obtained, call routing etc.

A Call Detail Record (CDR) can contain the identification of the start and end cell. Do remember, for the purposes of accuracy, a Call Detail Record is a single record of a mobile telephone call and is legally and Standards recognised. The mobile terminated call (MTC) CDR example above is included in my work that I was commissioned to prepare and published for Dr Bainbridge Aston University: Admissibility of Computer Evidence in Criminal Proceedings, 1998. The relevance of mentioning this is that there is nothing new about cell identification being recorded in a Call Detail Record.

The above is one example of the core-skills content available through my training courses and I have posted this information because I have heard from and read comments from those who have attended other providers' training courses who have received what is said to be forensic and expert training for the purposes of providing mobile telephone evidence and services and which the comments imply or infer that the training turns out to be partly or entirely unsuitable to deal with the understanding of the subject matter. This is leaving those who attended those training courses to vulnerability when examining, investigating or providing opinion about mobile telephone evidence.
