Abstract
Abstract In an Advanced Intelligent Telephone Network system, switching points are programmed to trigger a query to a Service Control Point ("SCP") in response to a dialed "500" number. The SCP performs a data request of an outside database storing service provider information, obtaining a service provider identification or a routing number corresponding to the dialed "500" number. The SCP then transmits a switching instruction to the service system point to route the call to the appropriate destination number.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
176 words
A method of controlling a telephone switching network including a control processor connected to a storage device for storing data, an originating switching system, a destination switching system, a home location register at a Global Title Translation address, and a plurality of telephones in communication with the originating and destination switching systems, each telephone having a corresponding telephone number and capable of calling a called telephone number, the called telephone number being a geographically independent number, the method comprising the steps, executed by the control processor, of: receiving from the originating switching system a switching query including a called number; sending to the storage device a data query including the called number; receiving from the storage device a data response, including at least an identification of the destination switching system, the Global Title Translation address of the home location register, or a routing number associated with the called number; and sending to the originating switching system a switching response, including the identification of a destination switching system or the routing number associated with the called number.
Claim 2
Independent Claim
176 words
A method of controlling a telephone switching network including a control processor connected to a storage device for storing data, an originating switching system, a destination switching system, a home location register at a Global Title Translation address, and a plurality of telephones in communication with the originating and destination switching systems, each telephone having a corresponding telephone number and capable of calling a called telephone number, the called telephone number being a geographically independent number, the method comprising the steps, executed by the control processor, of: receiving from the originating switching system a switching query including a called number; sending to the storage device a data query including the called number; receiving from the storage device a data response, including at least an identification of the destination switching system, the Global Title Translation address of the home location register, or a routing number associated with the called number; and sending to the originating switching system a switching response, including the identification of a destination switching system or the routing number associated with the called number.
Claim 3
Dependent Claim
51 words

Claim 4
Dependent Claim
15 words
The method of claim 1, wherein the called number includes a 500 service access code.
Claim 5
Dependent Claim
49 words
The method of claim 2, wherein the switching query and switching response are communicated according to a first communications protocol, the data query and data response are communicated according to a second communications protocol, and the location request and location response are communicated according to a third communications protocol.
Claim 6
Dependent Claim
15 words
The method of claim 4, wherein the called number includes a 500 number area code.
