Abstract

The invention relates to tagging messages on a telecommunications network to convey, to the receiving device, information regarding the message, such as potential malicious nature and intent. In an example, a telecommunications network node receives a request to transmit an SMS message from a first mobile device to a second mobile device. The telecommunications network node uses a fraud detection module to determine a likelihood of harm, an extent of possible damage and a category of the SMS message. Using the output of the fraud detection module, the telecommunications network node ascribes to the SMS message a message modification attribute value, for example a TP-PID value. The modified message is transmitted to the second mobile device, where it is displayed with a warning.

Claims20

Dependent claims

A network node in a telecommunications network for tagging messages, the network node comprising a non-transitory computer-readable medium having instructions stored thereon, where the instructions when executed by one or more processors of the network node cause the network node to:

receive, at the network node of the telecommunications network, a request to deliver a Short Message Service (SMS) message from a first mobile device to a second mobile device;
processing first metadata associated with the SMS message to determine a spam likelihood indicator value for the SMS message,
wherein the spam likelihood indicator value is indicative of whether the SMS message is a spam message;
generate, by the network node, a message modification attribute value using the spam likelihood indicator value;
modify the SMS message using the message modification attribute value to obtain a modified SMS message, wherein modifying the SMS message comprises updating a Transfer Protocol-Protocol Identifier (TP-PID) value of the SMS message to obtain an updated TP-PID value;
and
transmit, by the network node, the modified SMS message to the second mobile device.

4 more elements

One or more non-transitory, computer-readable media storing instructions thereon, where the instructions when executed by a network node of a telecommunications network, perform operations for operating the network node, the operations comprising:

receiving, at the network node of the telecommunications network, a request to deliver a Short Message Service (SMS) message from a first mobile device to a second mobile device;
processing first metadata associated with the SMS message to determine a spam likelihood indicator value for the SMS message,
wherein the spam likelihood indicator value is indicative of whether the SMS message is a spam message;
generating, by the network node, a message modification attribute value using the spam likelihood indicator value;
modifying the SMS message using the message modification attribute value to obtain a modified SMS message, wherein modifying the SMS message comprises updating a Transfer Protocol-Protocol Identifier (TP-PID) value of the SMS message;
and
transmitting, by the network node, the modified SMS message to the second mobile device.
