Method and system for utilizing an information delivery service in a local number portability environment

In an Advanced Intelligent Network (AIN) and with respect to an incoming call received at an origination switch, a method for delivering, to a destination switch, information obtained from an information delivery service database in a local number portability environment, the information delivery service database located remotely from the origination switch, the method comprising the steps of:

• (a) receiving, at the origination switch, the incoming call from an originating user number and directed to an end user number;
• (b) at the origination switch, determining whether the end user number is portable;
• (c) if the end user number is portable, then obtaining a location routing number corresponding to the end user number from a local number portability database located remotely from the origination switch;
• (d) determining whether the location routing number is associated with a destination switch designated to receive originating user information associated with a specific service feature;
• (e) if the location routing number is associated with the destination switch designated to receive originating user information associated with the specific service feature, then obtaining the originating user information associated with the specific service feature from the remote information delivery service database;
• (f) at the origination switch, populating the originating user information associated with the specific service feature and the location routing number corresponding to the end user number in a signaling message;
• and
• (g) based on the location routing number, transmitting, from the origination switch to the destination switch designated to receive originating user information associated with the specific service feature, the signaling message including the originating user information associated with the specific service feature.

In an Advanced Intelligent Network (AIN) and with respect to an incoming call received at a first switch, a system for delivering, to a second switch, information obtained from an information delivery service database in a local number portability environment, the information delivery service database located remotely from the first switch, comprising:

• a first switch operative to receive the incoming call from an originating user number and directed to an end user number and operative to determine whether the end user number is portable;
• a local number portability database remotely connected to the first switch, the local number portability database being operative to compare the end user number to a plurality of ported numbers for a match to one of the plurality of ported numbers, and if the end user number matches the one of the plurality of ported numbers, then the local number portability database being further operative to obtain a location routing number identifying a second switch and corresponding to the one of the ported numbers;
• an information delivery service database located remotely from the first switch and functionally connected through an interface between the local number portability database and the information delivery service database;
• the local number portability database being further operative to obtain a name corresponding to the originating user number from the information delivery service database;
• the local number portability database being further operative to provide the location routing number identifying the second switch and the name corresponding to the originating user number to the first switch;
• and
• the first switch being further operative to populate the location routing number identifying the second switch and the name corresponding to the originating user number in a signaling message, and based on the location routing number identifying the second switch, to transmit the name corresponding to the originating user number in the signaling message to the second switch for completing the incoming call.

In an Advanced Intelligent Network (AIN) and with respect to receiving an incoming call at an origination switch, a method for delivering, to a destination switch, information pertaining to a service feature obtained from an information delivery service database with a location routing number obtained from a local number portability database, the information delivery service database and the local number portability database located remotely from the origination switch, comprising the steps of:

• (a) receiving, at the origination switch, the incoming call from an originating user number and directed to an end user number, the end user number having a portable NPA-NXX;
• (b) at the origination switch, provisioning a trigger with respect to the portable NPA-NXX;
• (c) in response to the trigger,
• i. sending a query to the remote local number portability database,
• ii. obtaining a location routing number corresponding to the end user number from the remote local number portability database,
• iii. determining whether the service feature is associated with the location routing number, and
• iv. if the service feature is associated with the location routing number, then consulting the remote information delivery service database, and obtaining originating user information pertaining to the service feature from the remote information delivery service database;
• (d) at the origination switch, populating alpha-numeric fields located in a signaling message with the location routing number and the originating user information pertaining to the service feature;
• and
• (e) based on the location routing number, transmitting, from the origination switch to the destination switch, the signaling message including the originating user information pertaining to the service feature.
