LG Uplus took a major leap forward by establishing a Network Real-time Analytic Platform (NRAP) and a dedicated analysis environment called NAVIS with Cloudera's enterprise platform. This improved their limited monitoring system, which mainly used equipment-based data to monitor LTE and wired services.

NRAP stores a variety of highly applicable data sources and modifies them into meaningful data. This has greatly increased demand from LG Uplus business sectors and AI to apply NRAP to DX projects and other uses.

All processes are distributed across 350 Cloudera nodes and processed in less than a minute in near real time. This is impressive, especially considering they handle over 400TB of data per day.

NRAP's big data platform can now accommodate 17 million 4G/5G total and 5 million home/business service users. This is a significant increase from the 14 million LTE subscribers they previously supported.

The number of indicators has increased to more than 5,000, providing end-to-end analysis that allows LG Uplus to easily and accurately find the cause of service quality problems. This is a vast improvement from the 300 indicators they had in the previous 4G environment.

LG Uplus has also introduced an AI function to operate and expand the automatic detection of network failure root causes and network quality prediction.

LG Uplus has made significant strides in improving its customer center network response quality, reducing it from 2 days to a mere 5 minutes. This is a remarkable achievement that demonstrates the company's commitment to providing top-notch services to its customers.

The company has also increased its capacity, now supporting 17 million 4G/5G total subscribers and 5 million home/business service users, a substantial jump from its previous 13 million LTE subscribers. This increased capacity has enabled LG Uplus to meet the growing demands of its customers and stay ahead of the competition.

LG Uplus was challenged with a variety of data needs to analyze various 5G services, which included establishing a new big data system that could accommodate data from 5G and LTE services. The company also needed to prepare for a large number of digital transformation tasks for its customers, which was a significant undertaking.

Here are some of the key challenges LG Uplus faced:

LG U+ has faced its fair share of controversies. In January and February 2023, the company was hit by a series of DDoS attacks that interrupted data services and resulted in personal information leakage. This is a serious issue that highlights the importance of robust cybersecurity measures.

The attacks were so severe that they prompted LG U+ CEO Hwang Hyeon-sik to apologize for the company's insufficient cybersecurity infrastructure. The CEO acknowledged that the company's cybersecurity spending would increase by 100 billion won ($77.9 million) per year to prevent similar incidents in the future.

LG Uplus faced significant challenges in preparing for the 5G commercialization, particularly in South Korea where it was pushing for the first commercial service globally. To achieve this, the company needed to monitor how 5G services worked and respond to customer needs.

The existing big data platform's architecture had limitations in terms of data acceptance, analytics, and application. This created a risk of being unable to analyze the various elements of the 5G service as effectively as existing wired and wireless services.

Jinsoo Jang, Team Leader of LG Uplus NMS Development Team, highlighted the importance of innovation reputation. If LG Uplus failed to maintain its reputation for innovation, it would lose its initial momentum in a highly competitive market.

The company needed reliable high-quality services to maintain the 5G service as an essential pillar of telecom for the future. This would also enable the company to gain a competitive edge.
