GSM operators work together to fight fraudulent phone calls The Guardian Nigeria News

As part of measures to curb growing cases of fraudulent phone calls around the world, the Global System for Mobile Telecommunications Association (GSMA) is expanding its portfolio of fraud prevention services across the industry.

This move is expected to strengthen the telecommunications industry’s ability to counter robot calls and other unwanted or fraudulent calls.

Together with technology partner Mobileum, GSMA has developed a new international fraud deterrent system, unveiled Tuesday at MWC21 as a proof-of-concept model. GSMA is now inviting the global telecommunications industry to test the model.

The invitation is open to a range of global telecommunications stakeholders, including mobile and landline carriers, voice over IP operators, voice wholesalers and signaling around the world. The purpose of the test is to assess high-level cooperative fraud and annoying call prevention techniques.

The GSMA is an industry organization that represents the interests of mobile network operators worldwide. More than 750 mobile operators are full GSMA members and an additional 400 companies in the wider mobile ecosystem are associate members.

GSMA Chief Technical Officer Alex Sinclair said the U.S. Federal Communications Commission recently said fraudulent robot calls cost Americans about $ 10 billion annually, and most perpetrators operate overseas.

Sinclair said it was a challenge facing citizens around the world, so “why are we calling on telecommunications operators – mobile, landline, internet and wholesale – to share their insights and experiences so that together we can locate and mitigate these sources of fraud.”

The joint initiative will explore a series of tools using real fraud incidents that will help limit a wide variety of fraudulent and annoying calls. These include: Case handling – allowing multiple networks to work on a problem: Call path tracking – to find the source of a call when that source is hidden; Live threat monitoring and alarms – providing real-time insight and warnings of active fraud campaigns; Resident ID Address Book – providing an authenticated list of identifiers; and Call validation – to confirm the origin of a call.

Head of Risk Management at Mobileum Rui Paiva said, “By combining the industry’s collective intelligence and locally based intelligence with our latest technology, we can deliver gameplay support to deal with fraud,” said “Our cloud-based platform provides the necessary tools to make a material difference, delivering the results and improvements that everyone wants. “

However, the Nigerian Communications Commission (NCC) has been able to stem the tide, Nigeria in the last three-and-a-half years has been fighting call masking, call filling and SIM boxing, all of which are aimed at fraudulent call services.

SIM Boxing or Interconnect Bypass Fraud was one of the most common frauds in the telecommunications industry today. It occurs when calls made over the Internet are sent to Simboxes (machines that contain SIM cards), which redirects this illegal VoIP (voice over Internet Protocol) traffic to mobile networks.

Call masking on the other hand is when a call is masked or refilled when a number is intentionally sorted to a different route and SIM boxing to describe one of the many tools in use) has many dimensions.

According to experts, SIM boxing fraud costs the industry to lose about $ 3 billion in revenue annually. The CEO, NCC, Professor Garba Danbatta, described call masking as a phenomenon whereby an international call is disguised to appear as a local call on any GSM network in Nigeria while SIM Boxing on the other hand relates to electronic boxes or devices. with multiple SIMs that have the ability to stop calls at local interconnection rates.

He recalled that SIM Boxing started at a time when the Commission decided to revise international final rates from N3.90 per minute to N24.40 per minute for international incoming traffic, which gave technology handlers a chance to stop calls at N3.90 per minute. minute. and pull away the difference, thus cutting the revenue meant for the operators and implicitly the government. A SIM box, he explained, has the ability to receive and transmit calls unnoticed.

“However, the challenge is that these SIM boxes are never type-approved by the Commission, an indication that they are being used illegally in the country,” he said.

Determined to end the twin evil, the NCC had, visually, a letter with Ref: TSNI / GEN / VOL.4 / 115, directed the concerned licensees to ensure the cessation of call masking or resumption of activity in their networks. A deadline has been set. In addition, on August 3, 2017, at a stakeholder meeting organized by the Commission, in which the affected companies participated, it was resolved that a comprehensive investigation would be conducted by the NCC to determine the companies / licenses involved in the illegal action.

Licensees were warned to stop the practice. It was also agreed that identified culprits would be sanctioned as part of initiatives to prevent the negative impact of this impact on national security.
