Charging Data Record
GSM/UMTS networks generate charging data needed for billing, fraud detection and other applications. The 3rd Generation Partnership Project (3GPP) publishes a set of specifications to define the GSM/UMTS core network charging architecture and charging data. Information about a chargeable event (e.g. time of call set-up, duration of the call, amount of data transferred, etc) is called CDR (Charging Data Record). The 3GPP specifies CDR ASN.1 schemas for bearer level, subsystem level and service level.
uniGone releases the CDR Asn1API, a Java or C# library that provides a simple way to handle CDR specified in ASN.1 schemas for Circuit Switched domain, Packet Switched domain (i.e. GPRS), IM subsystem and MMS.
Transferred Account Procedure
Roaming is a key feature of GSM. Operators exchange call event details on these roaming subscribers. The GSM Association publishes the TAP3 protocol, a mechanism by which operators exchange roaming billing information. Data are defined using an ASN.1 schema.
uniGone releases the TAP3 Asn1API, a Java or C# library that provides a simple way to handle the data specified in the schema. Moreover the API comes with TAP3 Converter a useful tool used to convert TAP3 binary file (BER encoded) to an XML file and vice-versa.
