ABSTRACT:
A communications accounting system is provided wherein the transfer of call detail record information from a remotely located phone may be accomplished in an efficient manner. During non-billable processes or during airtime billed at a reduced rate, the call detail record (CDR) information from the previous registration is simultaneously sent to the collector system for processing to the billing system. More specifically, encrypted and compressed authorization information and call details records (CDRs) from the previous use of the phone are simultaneously communicated from the Cellular Call Computer--Programmable Off-line (C3PO) to the host computer system by modem or other suitable manner. At the validation server, the authorization information is decrypted and uncompressed and stripped away from the CDRs, while the call is live, and sent to an authorization service. While the validation system is working on completing the authorization, the system is uploading the CDRs from calls made since the last authorization attempt. These CDRs are stored for later processing. The invention also provides a roaming management system integrated with the accounting system. By the method of the instant invention, equipment is efficiently utilized, internal airtime charges are minimized, and customers are billed in a timely manner.
