IP detail record (IPDR)

IP Detail Record (IPDR) is to be used to define the essential elements of data exchange between network elements and operations support systems so that future IP services can be operated economically and billed in detail.

IPDR is intended to create an open standard for charging for existing services such as electronic mail, as well as real-time and multicast services, Internet telephony and multimedia messaging. Even with simple services such as e-mail, there are various cost-relevant factors such as e-mail size and attachment size, distance, time of day, and so on. For real-time services and VoIP with guaranteed quality of service, it gets much more complicated.

With IPDR, the initiative of the same name wants to create a uniform recording format with which the network operators can determine and charge for the services. To this end, it defines the governing parameters for IP transactions and provides extensibility for services and networks. The definitions of IPDR include an open record format for exchanging information between all systems involved in network management and support and accounting systems.
