System and method for determining tariffs for real-time calls involving ported directory numbers
First Claim
1. A method of determining a tariff for a real-time wireless service provided for a wireless telephone call, said method comprising the steps of:
- determining during call setup whether the call is made to or from a ported telephone number;
upon determining that the call is made to or from a ported telephone number, determining whether the ported telephone number points to a particular network;
rating the call with a first tariff if the ported telephone number points to the particular network; and
rating the call with a second tariff if the ported telephone number does not point to the particular network.

Abstract
A system and method for determining a tariff for a real-time wireless service such as a prepaid service (PPS) for a wireless telephone call. A Local Number Portability Point (LNPP) provides an interface between service scripts in a Service Control Point (SCP) or application server, and an LNP database. When an Initial Detection Point (IDP) message is received by the service scripts, a query is sent through the LNPP to the LNP database to determine whether the call is made to or from a ported telephone number. If so, a routing number is returned. The scripts determine whether the routing number points to the network operator'"'"'s own network or another, and notify a Service Data Point (SDP). If the routing number points to the operator'"'"'s own network, the SDP applies a first tariff to the call. If the routing number points to another network, the SDP applies a second tariff.

6. A method of determining a tariff for a real-time wireless service provided for a wireless call made to or from a ported telephone number, said method comprising the steps of:
-
receiving by real-time service scripts, a call setup message containing a called party number, said call setup message being formatted in a first signaling protocol;
sending the called party number to a protocol converter;
converting in the protocol converter, the first signaling protocol to a second signaling protocol compatible with a Local Number Portability (LNP) database;
sending a query containing the called party number from the protocol converter to the LNP database;
receiving a query result from the LNP database, said result containing a routing number if the called party number has been ported;
determining by the service scripts whether the routing number points to a particular network; and
rating the call with a first tariff if the routing number points to the particular network.

7. A system in a radio telecommunications network for determining a tariff for a real-time wireless service provided for a wireless telephone call, said system comprising:
-
means for accessing a Local Number Portability (LNP) database during call setup to determine whether the call is made to or from a ported telephone number;
means for determining whether the ported telephone number points to a particular network, in response to a determination that the call is made to or from a ported telephone number; and
means for assigning a tariff to the call in response to a determination that the call is made to or from a ported telephone number, and in response to a determination that the ported telephone number points to a particular network. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A Service Control Point (SCP) in a telecommunications network comprising:
-
service scripts that implement a real-time service, said scripts including;
means for receiving a call setup message containing a called party number; and
means for sending rated events to a Service Data Point (SDP) for assigning a tariff to a call; and
an interface that receives the called party number from the service scripts and sends a query message containing the called party number to a Local Number Portability (LNP) database, said interface receiving a query result from the LNP database containing a routing number if the called party number is ported, and passing the routing number to the service scripts;
wherein the means for sending rated events to the SDP sends an indication to the SDP of whether the called party number is ported-in or ported-out of a particular network. - View Dependent Claims (17, 18)

19. Service logic for implementing a real-time service in a telecommunications network, said service logic comprising:
-
means for receiving a call setup message containing a called party number;
means for sending the called party number to an interface with a Local Number Portability (LNP) database, and receiving a routing number from the interface if the LNP database reports that the called party number is ported, and means for sending rated events to a Service Data Point (SDP) for assigning a tariff to a call, said means for sending rated events notifying the SDP whether the called party number is ported-in or ported-out of a particular network, or whether the called party number is an un-ported number that belongs to the particular network. - View Dependent Claims (20)
