Billing Records

Billing Records & Call Sequence Tables (CST)

billing recordsThe network provider can serve information, beyond normal billing records, relating to mobile handset utilisation which can be especially valuable in identifying usage, activity, patterns and the movements of a given mobile telephone handset. This information can be served in a variety of formats and due to the structure and complexity is typically reviewed by telephone forensic experts to identify information of evidentiary value. The three most common formats include:

HANDSET BILLING RECORDS which are produced by the service provider with whom the customer is contracted. This information is derived from the wholesale billing systems of the Mobile Network Operator (MNO) which gives the service provider the date and time of each call, the number called and the duration. The service provider will manipulate this data to meet his own billing format and requirements and insert the call costs. The customer will receive a bill from the SP which shows the time and date of each call, the number called, the duration and the cost.

CDRs and mobile telephone network Billing Records

CALL DETAIL RECORDS (CDRs): This information is available only from the mobile network operators and shows the information from the wholesale handset billing records plus information on the cell sites (telephone masts) used during these call or messages.

Billing Records in Evidence

ENHANCED CALL DETAIL RECORDS (CDR’s) which again is only available from the network operators and maybe subject to a court order or other specialist requirement (i.e. authoritative police service sign off or defence solicitor identification). Some of the network operators produce these CDR’s which shows all the previous information plus the address of the cell site and the post code from a single database, others require a search of a separate system. This information is fundamental to each and every case where the accurate mapping of cell site coverage is required.

In accordance with the Data Retention Directive 2006/24/EC, UK network operators hold billing records and further information for between 6 to 12 months, meaning that it is essential to make the application for this data as soon as is practically possible. We are also experienced to comment upon matters concerning legislation including the ‘Data Protection Act 1998′ (DPA), ‘Communications Act 2003′ (CMA), ‘Regulation of Investigatory Powers Act 2000 (RIPA)’.
