Abstract

This Inter-Exchange Carrier Access arrangement uses the Automatic Number Identification (ANI) capability of the central switching office to eliminate the need for the customer to dial an authorization code when accessing an inter-exchange carrier via a facilities reseller telephone communication system. The central switching office transmits the calling party identification (ANI) digits to the facilities reseller telephone communication system when the customer dials the remote access code for the facilities reseller telephone communication system. These received ANI digits are compared by the facilities reseller telephone communication system with a list of authorized customers stored in memory. If a match occurs, the identity of the inter-exchange carrier preselected by the customer is retrieved from memory and the telephone communication system automatically outpulses the inter-exchange carrier access code to the central switching office. Once connected to the selected inter-exchange carrier, the telephone communication system completes the call by transmitting both the called number and the customer'"'"'s personal identification code to the inter-exchange carrier. The customer thereby has "dial 1" access through the facilities reseller telephone communication system to this inter-exchange carrier.

Claims

1. In a switching system, which is connected to a central switching office, which central switching office serves a plurality of inter-exchange carriers, a method of providing a calling party at a calling station on an incoming call connection through said central switching office to said switching system with dial 1 access to a preselected one of said inter-exchange carriers via said switching system, comprising the steps of:

receiving from said central switching office data identifying said calling station;

recording a called number dialed by said calling station and transmitted by said central switching office over said incoming call connection;

scanning a database in said switching system to determine the one of said inter-exchange carriers preselected by said calling station;

retrieving from said database, inter-exchange carrier access code associated with said preselected inter-exchange carrier; and

establishing a call connection from said incoming call connection through said switching system to said preselected inter-exchange carrier via said central switching office using said retrieved access code and said called number.

2. The method of claim 1 wherein the step of retrieving includes the steps of:

prompting said calling party over said incoming call connection to transmit authorization code data; and

comparing said authorization code data transmitted by said calling party with authorization code data stored in said database to validate the identity of said calling party.

3. The method of claim 1 wherein said step of retrieving includes the steps of:

prompting said calling party over said incoming call connection to provide authorization code and account code data; and

comparing said authorization code and account code data received from said calling party over said incoming call connection with authorization code and account code data stored in said database to validate the identity of said calling party.

4. In a switching system, which is connected to a central switching office, which central switching office serves a plurality of inter-exchange carriers, apparatus for providing a calling party at a calling station on an incoming call connection through said central switching office to said switching system with dial 1 access to a preselected one of said inter-exchange carriers via said switching system, comprising:

means for receiving from said central switching office data identifying said calling station;

means for recording a called number dialed by said calling station and transmitted by said central switching office over said incoming call connection;

means for scanning a database in said switching system to determine the one of said inter-exchange carriers preselected by said calling station;

means for retrieving from said database, inter-exchange carrier access code data associated with said preselected inter-exchange carrier; and

means for establishing a call connection from said incoming call connection through said switching system to said preselected inter-exchange carrier via said central switching office using said retrieved access code and said called number.

5. The apparatus of claim 4 wherein said retrieving means includes:

means for prompting said calling party over said incoming call connection to transmit authorization code data; and

means for comparing said authorization code data transmitted by said calling party with authorization code data stored in said database to validate the identity of said calling party.

6. The apparatus of claim 5 wherein said retrieving means includes:

means for prompting said calling party over said incoming call connection to provide authorization code and account code data; and

means responsive to authorization code and account code data transmitted by said calling party over said incoming call connection for comparing said authorization code and account code data received from said calling party and authorization code and account code data stored in said database to validate the identity of said calling party.
