name: CDR
full_form: Charging Data Record
context: Summary based on the input provided by Deutsche Telekom AG in CP-171048/SP-170344. This feature allows the correlation of charging relevant information by concatenation of applications or specific interconnection and roaming scenarios by providing a method to identify all network elements (including applications) generating CDR for offline charging within an IMS. It specifies the principle to determine the completeness of charging information in IMS architecture and for roaming architecture for voice over IMS with home routed traffic, and adds related CDR parameters and AVPs. The information taken is a new dedicated SIP parameter within the "P-Charging-Vector" header for tracking all Network Elements (NEs) and Application Server (AS) (including one or more related application ID's) on the call path for which a CDR will be written. Within the Billing Domain, this information helps to correlate the charging information collected from the IMS entities. The principles for Determination of
description: Charging Data Record (CDR) is a critical network attribute used in telecommunications billing and charging processes. It refers to the collection of data records generated by network elements and applications, which are essential for offline charging and correlating charging information within an IMS architecture.
explanation: The text describes CDR as a collection of data records used for billing and charging, specifically mentioning its role in correlating information within an IMS architecture. This points to CDR being a parameter used in the telecommunications billing domain.
