China Unicom deploys digital and intelligent support for ninth CIIE

According to China United Network Communications Group Co., Ltd, the ninth China International Import Expo opened on 5 November at the National Exhibition and Convention Centre (Shanghai). China Unicom has built an integrated communications framework spanning space, air, land and sea, merging connectivity, sensing, intelligence and security. It delivers communications assurance and smart services across four dimensions: network access, computing power, user services and cyber protection.

Full‑scale 5G‑A coverage has been rolled out across the venue. Using three‑carrier aggregation and massive MIMO, the operator has established a primary and backup network built around AAU and pRRU hardware. The configuration supports peak downlink throughput of 3Gbps and peak uplink throughput of 1Gbps. A low‑orbit satellite backhaul emergency networking system makes its debut in this round of support work, alongside base station vehicles, portable satellite terminals and unmanned aerial vehicles. The combined assets form a resilient space‑air‑ground emergency network designed to handle heavy visitor volumes.

Artificial intelligence computing resources are deployed at base station sites, paired with intelligent scheduling software to allocate network capacity dynamically. An independently developed smart operations hub draws together a broad set of monitoring metrics. It identifies risks automatically, allocates work orders by severity and runs scripted remediation, enabling sub‑second fault response and stable computing capacity for high‑definition streaming and immersive VR viewing.

China Unicom has upgraded the “CIIE One Tap” AI assistant in partnership with Shanghai Media Group. The tool supplies multimodal, multilingual guidance and enquiry functions. 5G live‑stream backpacks and slow‑stream VR services are available to broaden options for media distribution. A dedicated foreign‑language service line has been opened on the 10010 helpline, together with short‑term communications packages for overseas visitors. Staff at service halls and on‑site teams provide bilingual one‑stop transaction handling.

A three‑tier security regime operates through pre‑emptive inspection, on‑site attendance and rapid emergency repair. The team carries out optical cable patrols, stress testing and construction supervision, with a target response window of five minutes for any network failure. The operator has also collaborated with Qingpu District authorities to build a dedicated CIIE assurance intelligent agent, linked to the unified urban management platform. The system allows voice‑activated retrieval of crowd, video and event data for digital, intelligent scheduling during the major event.

Throughout the expo, China Unicom will advance its transition to a comprehensive digital and intelligent service provider, concentrating on four core business streams. Its computing and network infrastructure will support high‑level opening.
