Abstract

A method and system in a wireless communications network for restricting certain communication transactions to specific geographic areas in order to reduce the risk of communications fraud are presented. Initially, a list of communication transactions is stored such that the list includes communication transactions permitted to occur at each of a number of geographic locations. Thereafter, a communications transaction is initiated. In response to an initiation of the communications transaction, a geographic location of an originator of the communications transaction is determined. Next, the list of communication transactions is automatically scanned for communication transactions permitted to occur at the geographic location. If the communications transaction is not found among the list, the initiation of the communications transaction is thereafter terminated. Alternatively, if the communications transaction is found among the list, the communications transaction is thereafter permitted to continue. The geographic location can include a cell or cells maintained within the communications network.

Claims

1. A method in a wireless communications network for restricting toll call communications to specific geographic areas in order to reduce the risk of communications fraud, said method comprising the steps of:

specifying a plurality of geographic locations within said wireless communications network at which toll calls are permitted;

determining a current geographic location of an originator of a communications transaction within said wireless communication network in response to an initiation of said communications transaction;

determining if said communications transaction is a toll call;

permitting said communication transaction to continue if said communication transaction is not a toll call;

terminating said communications transaction if said communications transaction is a toll call and said current geographic location is not among said specified plurality of geographic locations within said wireless communications network at which toll calls are permitted; and

permitting said communications transactions to continue if said communications transaction is a toll call and said current geographic location is one of said specified plurality of geographic locations within said wireless communications network at which toll calls are permitted.

2. The method according to claim 1 wherein the step of determining a current geographic location of an originator of said communications transaction further comprises the step of:

determining whether said current geographic location is located within a cell of a cellular communications network.

3. The method of claim 1 wherein the step of determining a current geographic location of an originator of said communications transaction further comprises the step of:

determining a latitude and longitude of said originator.

4. The method of claim 1 wherein the step of terminating said communications transaction of said communications transaction is a toll call and said current geographic location is not among said specified plurality of geographic locations within said wireless communication network at which toll calls are permitted further comprises the steps of:

prompting an originator of said communications transaction to enter verification data;

testing said verification data for authenticity;

if as a result of testing said verification data for authenticity, said verification data is not found to be authentic, thereafter terminating said communications transaction; and

if as a result of testing said verification data for authenticity, said verification data is found to be authentic, thereafter permitting said communications transaction to continue.

5. A system in a wireless communications network for restricting toll call communications to specific geographic areas in order to reduce the risk of communications fraud, said system comprising:

means for specifying a plurality of geographic locations within said wireless communications network at which toll calls are permitted;

means for determining a current geographic location of an originator of a communications transaction within said wireless communication network in response to an initiation of said communications transaction;

means for determining if said communications transaction is a toll call;

means for permitting said communication transaction to continue if said communication transaction is not a toll call;

means for terminating said communications transaction if said communications transaction is a toll call and said current geographic location is not among said specified plurality of geographic locations within said wireless communications network at which toll calls are permitted; and

means for permitting said communications transactions to continue if said communications transaction is a toll call and said current geographic location is one of said specified plurality of geographic locations within said wireless communications network at which toll calls are permitted.

6. The system according to claim 5 wherein said communications transaction further comprises a cellular communications transaction.

7. The system according to claim 5 wherein said current geographic location comprises a cell within said cellular communications network.

8. The system according the claim 5 wherein said means for determining a current geographic location of an originator of a communications transaction within said wireless communications network comprises:

means for determining a latitude and longitude of said originator.

9. The system according to claim 5 wherein said means for terminating said communications transaction if said communications transaction is a toll call and said current geographic location is not among said specified plurality of geographic locations within said wireless communication network at which toll calls are permitted further comprises:

means for prompting an originator of said communications transaction to enter verification data;

means for testing said verification data for authenticity;

means for thereafter terminating said communications transaction, if as a result of testing said verification data for authenticity, said verification data is not found to be authentic; and

means for thereafter permitting said communications transaction to continue, if as a result of testing said verification data for authenticity, said verification data is found to be authentic.
