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).

Abstract: A method and system for delivering information obtained from an information delivery service database with a location routing number obtained from a local number portability database. A communication is received from an originating user number and directed to an end user number, and a determination may be made as to whether the end user number is a portable number. If the end user number is portable, then the end user number is compared to a plurality of ported numbers in the local number portability database for a match to one of the plurality of ported numbers. If the end user number matches one of the plurality of ported numbers in the local number portability database, then a location routing number is obtained corresponding to one of the ported numbers. In addition, information corresponding to the originating user number is obtained from the information delivery service database. Next, a signaling message is populated with the information.

Abstract: A system and method for routing communications to a terminating station associated with a porting subscriber directory number when the porting subscriber line 14a is cut-over from a donor switch 12a to a donee switch 12b. Upon cut-over of the porting subscriber line 14a, a local number portability (LNP) activation telephone call is placed to a dial-in platform 50 that activates a previously provisioned but inactive LNP database entry for the porting subscriber directory number. The LNP database entry is located in an LNP database 42a at a service control point (SCP) 28a. The dial-in platform 50 also activates a previously provisioned but inactive directory-number-level trigger for the porting subscriber directory number at the donor switch 12a. Activating the directory-number-level trigger for the porting subscriber directory number at the donor switch 12a causes the donor switch 12a to hold a subsequently received telephone call directed to the porting subscriber directory number.
