Abstract

A system and method for processing electronic data and voice audio calls providing an interLATA (Local Access Transport Area) fast connect routing scheme that bypasses an interexchange carrier. An interLATA communication circuit is established between a first switch in a first LATA and a second switch in a second LATA. The step of routing a call from the first switch to the second switch is performed. The call is routed to an interexchange carrier if the interexchange carrier is not a subscriber to a fast connect service. The step of bypassing the interexchange carrier is performed if the interexchange carrier is a subscriber to the fast connect service. Upon determining that the interexchange carrier is a subscriber to the fast connect service, the call is directly routed from the first switch located in the first LATA to the second switch located in the second LATA without utilizing interexchange carrier trunks or switches.

Claims

1. A method for establishing an interLATA (Local Access Transport Area) communication circuit between a first switch in a first LATA and a second switch in a second LATA comprising the steps of:

routing a call from the first switch to the second switch via an interexchange carrier if the interexchange carrier is not a subscriber to a fast connect service and

bypassing the interexchange carrier if the interexchange carrier is a subscriber to the fast connect service and directly routing the call from the first switch located in the first LATA to the second switch located in the second LATA.

2. A method according to claim 1, wherein at least one of the first and second switches is an access tandem switch.

3. A method according to claim 1, wherein at least one of the first and second switches is a mobile telecommunication switching office.

4. A method according to claim 1 including the step of sending an acknowledgement wink from the second switch to the first switch.

5. A method for establishing interLATA (Local Access Transport Area) communication in a switching system having an interexchange carrier, a first switch a second switch and a third switch comprising the steps of:

transmitting a signal from the first switch located in a first LATA to the second switch in a second LATA;

receiving the signal at the second switch;

determining if the interexchange carrier is a subscriber to a fast connect service; and

bypassing the interexchange carrier and routing the signal to the third switch if the interexchange carrier is a subscriber to the fast connect service.

6. The method according to claim 5 including the step of transmitting an acknowledgment wink from the second switch to the first switch upon receipt of the signal by the second switch.

7. A method according to claim 5, wherein the first and third switches are end office switches and the second switch is an access tandem switch.

8. A method according to claim 5 wherein a least one of the first, second or third switch is a mobile telecommunication switching office.

9. The method for establishing interLATA (Local Access Transport Area) communication between two end office switches comprising the steps of:

transmitting a signal initiating a communication circuit from a first end office switch to a first access tandem switch;

receiving the signal at the first access tandem switch and transmitting the signal from the first access tandem switch to an interexchange carrier if the interexchange carrier is not a subscriber to a fast connect service;

if the interexchange carrier is a subscriber to the fast connect service, routing the signal to a second access tandem switch;

receiving the signal at the second access tandem switch; and

transmitting the signal to a second end office switch completing the communication circuit.

10. A method according to claim 9 including the step of performing an analysis at the first end office switch to determine whether the interexchange carrier is a subscriber.

11. The method according to claim 9, including the step of performing an analysis at the first access tandem switch to determine whether the interexchange carrier is a subscriber.

12. The method according to claim 9 including the step of transmitting acknowledgement winks from the first end office switch, the first access tandem switch, the second access tandem switch and the second end office switch upon receipt of the signal.

13. A method according to claim 9, wherein at least one of the first and second end office switches is a mobile telecommunication switching office.

14. A method for establishing interLATA (Local Access Transport Area) communication between two customer premises equipment located in separate LATAs comprising the steps of:

transmitting a signal from a first customer premises equipment located in a first LATA;

receiving the signal at a first end office switch and transmitting the signal to a first access tandem switch;

receiving the signal at the first access tandem switch and transmitting an acknowledgement wink to the first end office;

routing the signal to an interexchange carrier if the interexchange carrier is not a subscriber;

if the interexchange carrier is a subscriber, routing the signal to a second access tandem switch;

receiving the signal at the second access tandem switch and transmitting an acknowledgment wink to the first access tandem switch;

transmitting the signal to a second end office switch;

receiving the signal at the second end office switch and transmitting an acknowledgment wink to the second access tandem switch; and

transmitting the signal to a second customer premises equipment establishing a communication circuit.

15. A method according to claim 14, wherein the signal contains call characterizing information.

16. A method according to claim 14, wherein at least one of the first or second customer premises equipment is a mobile station and at least one of the first or second end offices is a mobile telecommunications switching office.

17. A method according to claim 14, wherein the routing of the signal is performed by an analysis of the signal in a service control point database.

18. A switching network for establishing interLATA (Local Access Transport Area) communication between two end office switches comprising:

means for transmitting a signal initiating a communication circuit from a first end office switch to a first access tandem switch;

means for receiving the signal at the first access tandem switch and means for transmitting the signal from the first access tandem switch to an interexchange carrier if the interexchange carrier is not a subscriber to a fast connect service;

means for transmitting the signal directly to a second access tandem switch and bypassing the interexchange carrier if the interexchange carrier is a subscriber to the fast connect service;

means for receiving the signal at the second access tandem switch and means for transmitting the signal to a second end office switch completing the communication circuit.
