Abstract

The telecommunications network includes a mobile switching center coupled to a home location register database for accepting calls from a wireless handset, a Public Switched Telephone Network that carries calls between distant switching centers, and a local network for terminating calls. The system works while a wireless subscriber is outside their home calling area also known as “roaming”. The system includes a method for dynamically routing wireless inter-exchange (long distance) calls in a telecommunications network by sending transaction capabilities application part messages containing instructions regarding call handling. It includes a method for sending transaction capabilities application part messages containing call setup parameters between a mobile switching center and a service control platform and a method for billing the long distance calls on the wireless subscriber'"'"'s monthly statement.

Claims

1. A method of choosing which long distance company a wireless roamer uses based on the selection of the wireless roamer or its home wireless carrier comprising:

(1) sending a plurality of transaction capabilities application part messages between a wireless service control point and a wireless switching center, comprising the steps of;

(i) sending transaction capabilities application part message that validate a roamer (ii) Instruct the service mobile switch center to pass dialed number information and;

(2) routing of the call to a interactive voice response until to play a brief recorded message and;

(3) routing of the wireless call to the called party

2. The method of claim 1, wherein the wireless parameters comprise:

a mobile switching center identification number.

3. The method of claim 1, wherein the wireless parameters comprise:

a number dialed by a caller; and

a mobile switching center identification number.

4. The method of claim 1 wherein step (2) comprises:

(i) receiving the number dialed by the wireless subscriber and;

(ii) determine if it is a long distance call and;

(iii) sending instructions to the mobile switching center to change the call routing to the interactive voice response unit via an Public Switched Telephone Network.

5. The method of claim 1 wherein step (2) comprises:

(i) creating a table which will indicate by mobile switching center whether a dialed call is a long distance;

(ii) activating the serving mobile switching center to send dialed digits before a wireless call is routed sending the initial address message with the mobile identification number.

6. The method of claim 1 further comprising the following steps that are performed before step (1);

sending a query for one or more roaming parameters from a serving wireless mobile switching center to a home location register (HLR); and

sending one or more roaming parameters from the home location register to the subscriber'"'"'s home mobile switching center.

7. The method of claim 1 wherein said roaming parameters comprise:

a mobile identification number.

8. The method of claim 1 wherein said roaming parameters comprise:

a phone number dialed by the wireless subscriber.

9. The method of claim 1 further comprising the following steps that are performed before step (1):

signaling from a telephone to a local network;

signaling from the local network to a mobile switching center;

sending a query for one or more roaming parameters from the mobile switching center to a home location register; and

sending the roaming parameters from the home location register to the serving mobile switching center.

10. The method of claim 1 further comprising the following steps:

(3) signaling from the mobile switching center to an Public Switched Telephone Network;

(4) signaling from the Public Switched Telephone Network to a mobile switching center; and

(5) signaling from the mobile switching center to a wireless handset.

11. The method of claim 1, wherein the mobile switching center is instructed to send only inter-lata (long distance) toll calls.

12. The method of claim 1, wherein the mobile switching center is instructed to send information to a different home location register at call startup.

13. A method for use in billing of the redirected long distance calls n the wireless subscriber'"'"'s monthly statement comprising of:

(1) collecting the call detail information from the serving carrier;

(2) matching the call detail information with the toll charges or generation of a matching toll charge record and;

(3) creating a new record to be sent to the home carrier and;

(4) sending that record to a third party clearinghouse working on behalf of the wireless carrier

14. The method in accordance of claim 13 step 1 comprising of call detail information converted to an industry standard CIBER format.

15. The method in accordance of claim 13 step 2 comprising of an clearinghouse accepting industry records containing call information from multiple sources.

16. The method in accordance of claim 13 step 4 comprising of sending an industry standard format to subscriber'"'"'s home carrier.
