Abstract
A system can be operable to receive a call from a communication device and identify whether the call is a spoofed based on, for example, whether a caller party user equipment associated with a caller identification number (caller ID number) is in an “idle” status, whether there are inconsistencies in the geographic location associated with a calling party's network and the geographic location determined to be associated with the caller ID number presented, and whether the phone number presented as the caller ID number is registered with a calling party's network.
Claims20
A device, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
- determining, according to a consistency criterion, whether an area code applicable to a call from a communication device is consistent with a geographic area determined using an indicator associated with the call;
- and
- in response to determining that the area code is consistent with the geographic area, sending a message to network equipment associated with a service network servicing the communication device as an originating network for the communication device, wherein the message comprises a request to determine whether a caller identification number presented for the call is registered for a use of a service associated with the service network.
A method, comprising:
- determining, by network equipment comprising a processor and according to a consistency criterion, whether an area code applicable to a call from a mobile device is consistent with a geographic area determined using an indicator associated with the call;
- and
- in response to determining that the area code is consistent with the geographic area, sending, by the network equipment, a message to a network element associated with a service network servicing the mobile device as an originating network for the mobile device, wherein the message comprises a request to determine whether a caller identification number presented for the call is registered to use the service network.
A non-transitory machine-readable medium comprising executable instructions that, when executed by a processor of network equipment, facilitate performance of operations, the operations comprising:
- determining, according to a consistency criterion, whether an area code applicable to a call from a user equipment is consistent with a geographic area determined using an indicator associated with the call;
- and
- in response to determining that the area code is consistent with the geographic area, sending a message to service network equipment associated with a service network servicing the user equipment as an originating network for the user equipment, wherein the message comprises a request to determine whether a caller identification number presented for the call is registered to use a service enabled via the service network.
