ABSTRACT:
In a telecommunications network, a method and apparatus for decreasing access time of information normally stored in a data base, shared by a plurality of switching systems usually remote from all or most of the systems. One or more bit maps are used to store key indicators for each telephone number for which information may be required. In one specific embodiment, a bit map indicates whether the information is stored locally in the switch, so that an access to the remote database is not required. In another embodiment, a bit map stores an indication of whether the desired information is a default attribute, or one of a plurality of common attributes of the information being sought. Advantageously, the number of data accesses required of the remote data base is sharply reduced, thus reducing the average call set up time.
