US 2020/0053136 A1 · ORIGINATING CALLER VERIFICATION VIA INSERTION OF AN ATTESTATION PARAMETER

Abstract

The present disclosure describes techniques for verifying an identity of an originating device that initiates a VoIP communication with a recipient device. Specifically, an attestation parameter module is configured to detect a call request associated with a VoIP communication that is initiated by an originating device. The attestation parameter module may authenticate an identity of the originating device, and in doing so, insert an attestation parameter into an identity header of a modified SIP INVITE message sent to the recipient device. In response to receiving the modified SIP INVITE message with the attestation parameter, the telecommunication network associated with the recipient device may verify the identity of the originating device based on the attestation parameter included within the SIP INVITE message. In some examples, the attestation parameter module may generate and insert an attestation parameter within a modified SIP INVITE message that is initiated in a SIP/non-SIP telecommunication network.

Dependent claims

A network server of a first network, comprising:

one or more processors;
memory coupled to the one or more processors, the memory including one or more modules that are executable by the one or more processors to:
detect receipt of a call request initiated by an originating device within the first network, the call request configured to initiate a telephony communication with a Voice over Long-Term Evolution (VoLTE) recipient device within a second network;
verify an identity of the originating device;
in response to verifying the identity of the originating device as a known-permissible caller identity, generate an attested Session Internet Protocol (SIP) INVITE message that includes an attestation parameter, based at least in part on the identity of the originating device;
and
transmit, via the network server, the modified SIP INVITE message to the second network associated with the VoLTE recipient device, the VoLTE recipient device to use the attestation parameter within the modified SIP INVITE message to verify the identity of the originating device.

4 more elements

A computer-implemented method, comprising:

under control of one or more processors:
detecting, at a TAS of a Home Public Land Mobile Network (HPLMN), receipt of a SIP INVITE message initiated by a first VoLTE device within the HPLMN, the SIP INVITE message to initiate a telephony communication with a second VoLTE device in a Visited Public Land Mobile Network (VPLMN);
retrieving, from the first VoLTE device, a device identifier associated with the first VoLTE device;
verifying an identity of the first VoLTE device, based at least in part on the device identifier;
generating an attestation parameter for the first VoLTE device, based at least in part on verifying the identity of the first VoLTE device;
generating a modified SIP INVITE message by modifying an identity header of the SIP message to include the attestation parameter;
and
transmitting, to the VPLMN, the modified SIP INVITE message.

5 more elements

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed on one or more processors, cause the one or more processors to perform acts comprising:

detecting, at a Mobile Switching Circuit (MSC) of a non-SIP network, receipt of a call request from an originating device within the non-SIP network to initiate a telephony communication with a VoLTE recipient device within a SIP network;
retrieving from the call request an originating device identifier associated with the originating device;
verifying an identity of the originating device, based at least in part on the originating device identifier;
in response to verifying the identity of the originating device as a known-permissible caller identity, generating an attestation parameter that identifies the originating device as the known-permissible caller identity;
generating a SIP INVITE message that is configured to initiate the telephony communication between the originating device and the VoLTE recipient device;
generating a modified SIP INVITE message by modifying an identity header of the SIP INVITE message to include the attestation parameter;
and
transmitting, to the SIP network, the modified SIP INVITE message.
