Abstract

A system and method for providing directory assistance service and information in a multiple service provider and a local number portability environment. An operator services system (OPSS) (15) is functionally connected to a first and a second database (24, 26). Preferably, the first database (24) is a directory assistance database, and the second database (26) is a directory assistance-local number portability (DA-LNP) database. Upon receipt of a request for a directory number associated with the name of a party, the OPSS (15) makes a first query of the first database (24) for first search results relating to the name of the party. Preferably, the OPSS (15) also concurrently makes a second query, but of the second database (26) for second search results relating to the name of the party. The first and second databases are searched based on the name of the party. The first and second search results are provided to the OPSS (15). In response to receipt of the first and second search results, the OPSS (15) consolidates both search results into consolidated search results. Preferably, the OPSS (15) eliminates any duplicative entry between the first and second search results. The OPSS (15) then provides the consolidated search results to a display (21). The consolidated search results are displayed and are used to provide the directory assistance service in response to the request for the name of the party.

said display being operative to display said consolidated search results, whereby said consolidated search results comprise a basis for providing said directory assistance service in response to said request for said directory number associated with said name of said called party.

7. A telecommunications system for providing directory assistance information to a calling party who has requested a directory number of a called party, comprising:

a directory assistance-local number portability (DA-LNP) database including one or more entries with each entry further comprising directory assistance information;

an operator services system (OPSS), said OPSS being operative

to receive a request from said calling party for said directory number of said called party, said directory number representing one that said calling party desires to call, in geographic areas where there exist multiple competitive telecommunication service providers, and

to make a query of said DA-LNP database with respect to said request based on the name of said called party;

in response to said query from said OPSS, said DA-LNP database being operative

to check said one or more entries for a matching entry to said called party based on said name of said called party, and

if said matching entry is found, to provide said OPSS with the directory assistance information corresponding to said matching entry; and

said OPSS being further operative to receive said directory assistance information corresponding to said matching entry from said DA-LNP database.

8. The system of claim 7, wherein said directory assistance information corresponding to said matching entry further comprises a service provider identification corresponding to said name of said called party.

9. The system of claim 7, further comprising a display;

wherein said OPSS is further operative to provide said directory assistance information corresponding to said matching entry to said display; and

wherein said display is operative to receive said directory assistance information corresponding to said matching entry from said OPSS and to display said directory assistance information corresponding to said matching entry.

10. In a telecommunications system, a method for providing directory assistance service, comprising the steps of:

a. receiving a request from a calling party for a directory number associated with the name of a called party that said calling party desires to call;

b. in response to said request,

using said name and searching a first database for first search results relating to said name of said called party, and

using said name and searching a second database for second search results, wherein said first search results and said second results both relate to said name of said called party;

c. consolidating said first search results and said second search results into consolidated search results; and
