A billing system for a telecommunications network uses a monitoring software agent to monitor messages, indicative of individual calls on the network, passing between a service switching point and a service control point. Call record information is extracted and is stored in a local call record database. Information from each call record database is then passed on to a central database, using updating mobile agents, the central database being accessible to such agents and report building agents which can extract billing information as requested by an operator. By monitoring the messages as they pass, the system can provide real time billing information without needing to poll the switch at the service switching point.

By coupling a rating engine with call processing, rating rules are generated that enable a flexible interface between call process and call rating without necessitating that fixed data be passed between them. The real time charging system (RCS) provides a process that creates a generic entity, called a bucket, and uses it to keep track of account information and/or to count types of usage. The bucket allows an operator to define accounts and usage counters and how they are used as part of the rating rules. Use of these buckets is defined in rating rules, thus turning control over subscriber account and usage counters to the network operator. Further, the RCS provides a calendar option for limiting times during which calls to general telephone numbers can be made or received.
