LG Uplus deploys autonomous network to support BTS concert traffic in Seoul

LG Uplus says it will activate an Autonomous Network-based pre-emptive response for BTS’s large concert at Gwanghwamun Square in downtown Seoul on the 21st. The carrier plans to deploy additional mobile base stations and temporary repeaters to ensure stable mobile service as hundreds of thousands of people are expected to gather for the event.

To support the crowd, LG Uplus will add infrastructure in and around Gwanghwamun Square and in about 10 nearby areas. The company will also check existing base station capacity and carry out pre-event optimizations to prevent LTE and 5G traffic from concentrating in a few spots.

The Autonomous Network approach involves pre-setting the operating conditions for local cells before the event and monitoring traffic in real time during the event. If traffic concentrates in a single cell, the system automatically adjusts parameters such as base station power and connection maintenance timing to distribute load to neighboring cells.

On the ground, LG Uplus will station field personnel on the event day to monitor equipment status and network quality. A Magok Network Operations Center will run an emergency response system, coordinating with the field and situation-room teams to implement immediate optimizations as needed.

LG Uplus says it will continue to refine autonomous-network-based operations for large concerts, sports events, and big-city gatherings where traffic surges are common, aiming to keep users connected during peak moments.

Kwak Jun-Young, an executive responsible for metropolitan infrastructure at LG Uplus, emphasized that large crowds can cause sudden spikes in traffic and that pre-checks and real-time monitoring are essential. He said the company will use its autonomous-network-based proactive response and coordinated field-situation-room operations to maintain stable service for users.

Why this matters beyond Korea: the approach highlights how major telecoms manage network capacity for high-profile events, a concern shared by U.S. carriers planning NFL games, major concerts, political rallies, or conventions. Autonomous networks that forecast load and automatically reallocate resources can reduce outages and improve user experience, with implications for 5G-enabled mass events, disaster preparedness, and cross-border supply chains for temporary telecom infrastructure and backhaul during large gatherings.
