Prepaid CDR/EDR calls processing – CDR/EDR Parser.

An application which receives the CDR (Call Details Record) files binary encoded files in ASN.1 standards. The binary encoded file contains Prepaid Customer usage like Voice, SMS, MMS, GPRS, BONUS and Adjustments. The application decodes the file CDR-by-CDR, loads into memory and updates the prepaid database. Various Self Serve applications use the latest prepaid customer data from the database. The binary encoded files are sent from Alcatel Integrated Convergent engine for prepaid usage.

CDR/EDR file parser: A file parser was developed to parse all the CDR files and update the prepaid database. The parser needs to read and parse the file line-by-line update the database with in 5 mins of time. Files are received every 5 minutes from the Alcatel central. Each file size is of average 100MB. The parser was written using the ASN.1 compiler. It translates an Abstract Syntax Notation 1(ASN.1) source file into computer language source files that allow ASN.1 data to be decoded. The parser C API was written on top of the compiler, specific to the application logics. Memory management and searching of the data were the major challenges in the project. Each CDR is a concatenation of the T-L-V (Tag-Length-Value) formats, which are binary encoded as per ASN.1 (Telecom) standards.

Customer File Parser: A file parser, which parses and updates the prepaid database by the end of the day. It performs the reconciliation of the latest data in the file sent by the Alcatel prepaid customer base.

Language and Platform: C, Perl, and Mysql on Linux.

Team Size: 1

Responsibilities: Prepared Macro, Micro design, system test case documents and developed CDR parser based on the ASN.1 C standards . Code check in has been done in Rational Clear case server.
