Abstract:

Special service call processing, such as 800 processing, is improved in accordance with the present invention. A data base includes a customer subscription record segment which stores call processing data keyed at least in part on a dialed 800 number. The subscription record for a customer is hierarchical in that it includes a head entry (for customers using basic or immediate service). The head entry for customers using advanced service, when accessed, produces Originating Area ID identification (OAID). Subsequent accesses to the data base use the OAID in order to access additional records for chronological time processing. Those additional records may include time band or day band arrays. Accessing a day band array will produce a Day Band ID identification (DBID). The DBID can be used on a subsequent access to identify a time band array.
