ABSTRACT:
A method for formatting CDRs to reduce storage and processing requirements within a switch or telecommunications network which formats CDRs in accordance with the disclosed techniques. A switch includes a call condense agent for collecting raw call information for calls handled thereby and a formatting agent for selecting, based upon an examination of said raw call information, an optimal data structure for formatting the raw call information and for producing a CDR by formatting said raw call information in accordance with said optimal data structure. The optimal data structure is that which best fits the raw call information. The best fitting data structure is chosen by determining, for each template, which call detail types are classified as "must-have" or "don't care" and selecting the template which includes all of the must-have call details and the greatest number of "don't care" call details captured by the raw call information and the least amount of store for call detail types which were not captured by the raw call information. The switch also includes a storage facility, coupled to the call condense and formatting agents, for maintaining the raw call information, a plurality of data structures and the CDRs therein. If the method is performed within a telecommunications network, the formatter and storage facility will reside within a billing server coupled to the switch.
