摘要： 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.

摘要： 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. The donor switch 12a then transmits a query message to the SCP 28a and holds the telephone call until it receives a response message including routing instructions from the SCP 28a. Activating the LNP database entry for the porting subscriber directory number in the LNP database 42a at the SCP 28a associates the porting subscriber directory number with the donee switch 12b. Activating the LNP database entry therefore allows the SCP 28 to determine the correct terminating switch for the held telephone call, which after cut-over, is the donee switch 12b.

摘要： 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. Finally, the signaling message with respect to the routing of the communication based on the location routing number is transmitted. The signaling message includes the information obtained from the information delivery service database. The information may comprise an originating user number, a name, or a combination of the originating user number and the name. Therefore, the task of obtaining the information corresponding to the originating user number from the information delivery service database may further comprise obtaining the originating user number and name.
