ABSTRACT:
This invention relates to a method and apparatus for improving the performance of intelligent networks. In a departure from the prior art, when a data base system, such as a service control point, receives an inquiry from a switching system, if the data base system recognizes that it cannot provide the complete data requested by the inquiry, it directly launches another inquiry to another data base system to provide the missing data. Advantageously, such an arrangement reduces the number of messages transmitted among switching systems and data base systems.
