....through the home network; and another required that the GSM short message service (SMS) be used to send the desired number to the home network for call completion. Recently, prepaid roaming solutions have been proposed based on the Customised Applications for Mobile network Enhanced Logic (CAMEL) [ETSI00g] features. CAMEL allows home NOs to provide operatorspecific services to their roaming subscribers. When a roaming user initiates a call, the CAMEL process in their home network is contacted by the visited network for further instructions. The charging related instructions allow the home network ....

....3 rd Generation Partnership Project (3GPP) an international consortium of telecommunications standards bodies, was formed, in December 1998, to produce technical specifications for UMTS. The 3GPP strategy is to build on existing GSM systems [CMO99] and they recommend the use of GSM GPRS billing [ETSI00a, ETSI00f]. TAP3 records will be enhanced to cater for usage of new resources and services [3GPP99a] However, variable bandwidth in a multimedia call, such as that caused by adding or removing video streams, will result in a large number of CDRs. Long calls must also generate several CDRs, to allow timely ....

....Users share a dynamically allocated pool of packet data channels, one per GSM time slot, with a maximum throughput of 115 kbit s. Since it is packet based, rather than circuit switched, the radio capacity is only used when actually transmitting or receiving data. Accordingly, new GPRS CDRs [ETSI00c] have been defined to record volume usage for charging and billing.

....and the identity of the external network used. Time stamped data is added to the CDRs throughout the session to reflect changes in the radio capacity or tariff time. If the IP destination address is optionally recorded, new CDRs are needed for each change of address. The GTP charging protocol [ETSI00c], an extension of the GPRS Tunnel Protocol (GTP) is defined to transport the CDRs reliably, using UDP TCP over IP to a charging gateway, where tariffs are applied. The Enhanced Data Rates for GSM Evolution (EDGE) FNO99, FMMO99] is a radio modulation technique allowing over 384 kbit s for packet ....

....contents of a CDR vary from operator to operator. This is partly due to their use not only for billing but also for the measurement of traffic and quality of service. Switch architectures from different manufacturers also produce information in different formats. Recent standards for call records [ETSI99c, Telc99, ETSI98c, ITU98a] do exist, but are not yet widely adhered to. However, there are some critical fields for billing, usually present in some form. These are: Source of call. The CDR must uniquely identify the party to charge. Normally, calls are billed to the owner of the phone from which a call is placed, ....

A will be billed for the originating leg (TT1) while B will be billed for the roaming leg (TT2) and terminating leg (TT3) There are 17 different types of GSM toll tickets and the one for a mobile originated call contains 55 possible fields [ETSI99c]. The International Mobile Subscriber Identity (IMSI) identifies the source of a mobile originated call. In addition to regular CDR fields, the toll ticket contains location area, cell ID, radio channel allocation and international mobile equipment identity (IMEI) 12 Home NO (for A and B) ....
