Network Stability

Huawei has a well-established business continuity management (BCM) system that provides a contingency plan for ten typical scenarios (such as for earthquakes or outbreaks of war) and allows us to quickly restore customer networks and resume stable operations following critical emergencies, thus helping safeguard life and property. Even under extreme conditions, our employees will do their utmost to support network stability. This is the responsibility shouldered by each and every Huawei employee. This obligation outweighs any commercial interests.

Huawei invests heavily in network stability, striving to ensure that everyone is able to communicate, access data, and share information whenever and wherever needed. Specifically, we have established a comprehensive customer network support system that considers a range of factors, including organizational structures, designated personnel, processes, and IT tools. We have also established a mature BCM system that provides a contingency plan for emergencies (such as for earthquakes or outbreaks of war). This system allows us to quickly restore customer networks and resume stable operations following critical emergencies, thus helping safeguard life and property.

We have established three global and nine regional technical assistance centers. More than 3,900 Huawei technical support engineers provide services worldwide on a 24/7 basis. In 2016, we ensured smooth communication for nearly 3 billion people worldwide, and supported the stable operations of over 1,500 networks in more than 170 countries and regions. We guaranteed network availability during nearly 200 major events, natural disasters, and special occasions (such as the magnitude 7.8 earthquake in Ecuador, the G20 Summit, and the Hajj in Saudi Arabia).

Restoring Communication Networks Following the 2016 Earthquake in Ecuador

On April 16, 2016, a powerful 7.8 magnitude earthquake occurred just outside the small town of Muisne in Ecuador, with tremors spread across the five provinces of Manabi, Guayas, Esmeraldas, Santo, and Domingo. This was the most devastating earthquake in the country in nearly 70 years. Duty called. Within 30 minutes after the earthquake, Huawei Ecuador initiated its Business Continuity Management (BCM) procedures for emergencies and formed an emergency assurance team. We quickly analyzed and identified network problems, and discussed solutions with the customer to deal with damaged network equipment.

Huawei Ecuador's emergency repair personnel were then assigned to multiple smaller sub-teams to work with customer personnel. Braving the danger of continuing aftershocks, power outages, and supply shortages, the teams delved deep into the disaster zones of Portoviejo, Jama, and Pedernales to make emergency repairs. After five hard days of work, the fiber optics team repaired 51 fiber optic lines, re-adjusted etwork connections, established new mirror sites and two redundancy links for four disaster-stricken provinces, and added two additional sites in Portoviejo. These efforts ensured normal communication in the disaster area.

More than 800 aftershocks were felt in the disaster area during the following week. Water and power lines were cut, and materials were in short supply. Because the power grid had been severely damaged in the earthquake zone, some base stations were facing power shortages. In addition, voice traffic following the earthquake was multiple times its normal levels. Huawei Ecuador quickly procured and dispatched diesel generators and lighting systems, and worked to disperse the network congestion being faced by local carriers. Nearly 300 Huawei staff members were directly involved in the network recovery work. Focused on a single aim, the team worked urgently to repair communication equipment and maintain the normal operation of the telecom network.

Furthermore, Huawei Ecuador donated 11 tons of spring water to the region of Portoviejo, providing a source of drinking water to residents in this area. Huawei Ecuador also proactively coordinated vehicles for three Chinese rescue teams, and provided emergency supplies to ensure the teams were able to gain quick and efficient access to areas most in need.

Supporting Network Stability at the Hangzhou G20 Summit

The 11th G20 Summit was held from September 4 to 5, 2016 in Hangzhou, China. Huawei assigned high priority to supporting network availability for the event, and therefore set up a G20 Communication Support Project Team comprised of personnel from field operations, R&D, and related departments. To enable network stability during the summit, the Project Team kept in close contact with the customer, clarified objectives, and developed a comprehensive plan.

Beginning in March 2016, Huawei experts and engineers invested over 8,600 person-days in enormous amounts of work. This included network-wide inspections, addressing any issues that were uncovered, and updating network emergency response plans. In total, Huawei deployed, expanded, and upgraded over 5,000 base stations to prevent potential network risks so as to lay a solid foundation for a successful summit.

Beginning in early August 2016, Huawei assigned 431 staff members to work onsite and 280 staff members to support the project remotely. The onsite and remote teams worked together seamlessly, and provided 24/7 uninterrupted support for network operations. Huawei also established a special G20 line to ensure rapid response to any issues that might occur during the summit. From August 20 to September 7, 2016, Huawei's work involved China's three major carriers, 24 key regions, 6 key transportation routes, 11,000 private transmission lines, 13,000 international roaming users, 868,000 IPTV live broadcast users, as well as VoLTE, FDD/TDD, and OTT services. The network operated stably throughout this time period, and the quality of all the services remained high. Huawei successfully completed the project, with zero network incidents, disruptions, and complaints.

Huawei's robust support provided strong backing to a variety of telecom services. We won strong customer recognition through our professional processes and team organization, visualized real-time monitoring, and rapid emergency response measures. Our work during the G20 Summit demonstrated Huawei's ability to provide high-quality support to major events. We lived up to our commitment to ensure stable network operation, and fulfilled our social responsibility.

Guaranteeing Connectivity for the Asian-African Conference

To celebrate the 60th anniversary of the Bandung Conference, leaders from over 100 Asian and African countries and 25 international organizations attended the Asian-African Conference, which was covered by thousands of reporters. While many festive activities were underway, some involving tens of thousands of people and high demand for Internet access, network quality and stability were essential.

Starting two months before the conference, we began organizing resources to prepare for network stability assurance. Specifically, we established a network stability assurance team and assigned over 100 experts and engineers to take part in the extensive and intense preparatory work. This included predicting user behavior and traffic trends; network planning; inspections; developing an emergency response plan jointly with the customer; network deployment and equipment installation; and preparing emergency communications vehicles.

During the event, the conference hall in Jakarta saw a 70% increase in 3G traffic, and 4G traffic rose seven-fold above normal levels. The celebrations commemorating the Bandung Conference were the culmination of the event. On April 25, a huge celebration took place on a walking street near the former site of the Bandung Conference. The mayor and tens of thousands of citizens flocked to the site to witness the festivities and share the moments online or via phone calls. As a result, voice and data traffic peaked several times, putting great pressure on the local networks and base stations. It was quite difficult to guarantee network security and experience.

Our onsite network optimization experts worked with the customer team to continuously refine our work plan every day based on the developing situations. Through our joint efforts, the customer’s network operated stably during the conference and celebrations, recording zero network incidents and disruptions. Our efforts ensured a superior communication experience for the government officials and citizens participating in the celebrations.

Against All Odds: Restoring Networks After the Nepal Earthquake

On April 25, 2015, a devastating earthquake with a magnitude of 8.1 rocked Nepal, causing severe damage and many casualties in local communities. Communications infrastructure in the worst-hit areas was badly damaged.

Despite the risk of aftershocks, engineers in our Nepal Representative Office ran all the way to the local carrier’s equipment room within 20 minutes after the earthquake. They knew they had to work with the customer to keep the network operational. Back at the office, Huawei launched a business continuity management mechanism and emergency response plan, set up a disaster recovery team, issued an earthquake alert, and began stocking medical supplies and other essential items. The supply chain and procurement departments swung into action to support our engineers in the field. Within 30 hours, the first shipment of emergency equipment arrived.

In the aftermath of the earthquake, voice traffic on local networks rose to four times its normal levels, and it remained high over the following week. This placed enormous strain on the already damaged networks. The power grid was down, and many base stations did not have enough diesel or other energies to keep their emergency generators running, so even key stations began failing. We swiftly coordinated all resources (diesel and satellite phones). A joint technicalsupport group with employees from our Shenzhen HQ, Southern-East Asia Region, India Representative Office,and Nepal Office worked closely with the customer to keep voice traffic flowing while we scrambled emergency repairs. As a result, we were able to restore the networks, help those in the earthquake zone to reach their families, enable rescuers to stay connected, and ensure that the media could report on the disaster and the relief efforts.

Twenty-four hours after the earthquake, Huawei and the customer had repaired 40 key base stations at hospitals, government agencies, disaster relief centers, and embassies. Over the next few days, we cut the number of non-functional base stations from 30% to below 6%. Some of our competitors were unable to organize effective disaster recovery efforts, so we helped our customer repair 260 non-Huawei base stations. In areas where the roads were blocked, our engineers were ferried by helicopter deep into the earthquake zone to restore communications.

Because of these comprehensive measures, local network equipment was able to perform stably with dramatically reduced congestion, even though voice traffic remained high one week after the earthquake. Once again, we lived up to our commitment with our actions.

Sharing the Glory of the World Cup Around the Globe

The 2014 FIFA World Cup came to a splendid end with Germany winning the championship and Shakira's voice still lingering in the Maracanã Stadium. The breathtaking 64 matches captured the attention of the entire world.

As a major network equipment supplier in Brazil, Huawei offered customized communications support services to four major Brazilian carriers: Vivo, Oi, Claro, and TIM. With our professionalism, precision, perseverance, and solidarity, our team supported stable network operations during the World Cup.

A Digital Sports Feast

From June 12 to July 13, 2014, the 20th FIFA World Cup was held in 12 cities across Brazil. Nearly 3.3 million spectators watched matches in the stadiums, while millions more did so in football parks, bars, and other locations. They employed a variety of devices – mobile phones, laptops, tablets, and even smart watches – to upload photos and videos to hundreds of social networking platforms and apps (e.g., Facebook, Twitter, and WeChat). Some shared special moments with friends over their phones. Additionally, media outlets in more than 100 countries and regions broadcast the matches live to hundreds of millions of people around the world.

Statistics showed that mobile subscribers grew by 48% and data traffic by 400% in Brazil during the event. During the final on July 13, more than 70,000 live spectators uploaded nearly 2.6 million photos, equivalent to 1.43 TB of data. This year's World Cup was an indisputable digital sports feast.

Efforts Behind a Superior User Experience

Many challenges – spikes in users and data traffic, numerous hotspots, complicated user behaviors, and unpredictable business models – might compromise network stability. Failure to promptly restore networks would have seriously affected broadcasting.

Huawei has amassed considerable experience in supporting networks in previous key sports events; for example, the Beijing Olympics, the London Olympics, and the FIFA World Cup in South Africa. Nevertheless, Huawei's team took its job seriously by offering consulting services for network technology, monitoring network operations, and ensuring the availability of spare parts. With Huawei's support, the carriers successfully delivered quality voice and data services to ensure a superior experience for people all over the world.


A digital sports feast

In the year leading up to the event, Huawei provided network consulting services for carriers' live networks and identified network risks through traffic model analysis, traffic volume forecasting, network evaluation, network coverage & capacity analysis, and user behavior and experience assessments. The team also conducted special analysis and forecasting on the LTE traffic model.

During the World Cup, Huawei's team monitored carriers' networks in real time, analyzed problems, and optimized dynamic parameters. Together with the carriers, Huawei developed emergency plans for immediate response to network faults, guaranteeing optimal network performance at all times. Following the event, Huawei quickly restored and optimized temporary parameters to keep the networks stable over the long term.

To ensure network continuity during all 120 key occasions in 12 cities, Huawei's team was divided into two groups that took turns supporting the networks 24/7.

Ensuring Zero Network Interruptions

Although the peak data traffic volume during the event was 92% higher than usual, Huawei guaranteed unexpectedly high network Key Performance Indicators (KPIs). During the final between Germany and Argentina, the carrier that provided coverage for the stadium reached an access success rate of over 96% for traditional voice services and over 98% for 3G data services. Notably, the access success rate for 4G services even reached 99%. Through unremitting efforts, Huawei successfully ensured zero network interruptions or incidents, contributing to the huge success of the World Cup.

It was precisely the stable networks that rapidly spread news around the globe as it happened, whether it was witnessing Chile creating miracles on the pitch, when the Algerian team battled with the Germans, or when famous faces left the field in defeat. These networks wouldn't have been able to run stably without Huawei, whose efforts contributed greatly to this digital sports feast.
