Ericsson, a mobile network equipment manufacturer, confirmed that the software problem was the cause of network outages for operators of the two operators and other markets.
Erjeshin President and CEO Borje Ekholm said: "The software that causes these problems is gradually being phased out. We apologize not only to our customers but also to our customers. We work hard to ensure that our customers are minimally affected and their services are restored as soon as possible. ."
SoftBank said earlier that the disruption of the network was due to the exchange of its high-speed wireless LTE network (ie 4G). The Japanese company originally planned to list its domestic business with a $21 billion initial public offering (IPO) later this month. The company said the problem was resolved in four and a half hours by restoring the old Ericsson software.
According to Ericsson, operators in 11 countries have been affected by the failure. Ericsson said preliminary analysis indicated that the expired certificate in the software version installed by the affected customer was the cause of the incident. It said that the network services of most affected customers have been successfully restored that day and that it is working closely with the remaining customers who are still experiencing problems.
O2, a subsidiary of Spain's Telefonica, said that customers using its network, such as Tesco Mobile, Sky Mobile and GiffGaff customers, were affected by the disruption of the network.
O2 CEO Mark Evans said his team is working with Ericsson to find a quick solution.
Consumers who use the O2 service who do not have access to the Internet or applications are beginning to complain to the social media about the incident. This incident also appeared on the live information display of the London bus.
Ericsson used to be the world's largest supplier of mobile communication equipment, but it has been China'sHuaweiReplaced by Nokia in Finland. Ericsson is almost certain to recover from the market demand for the next generation of 5G communication equipment, and even benefit from the current event surrounding the market leader Huawei. On Thursday, Huawei became the focus of attention because of the tension between the United States and China.
According to one source, Huawei executive Meng Xizhou is the daughter of the founder and CEO of Huawei. She was arrested on Wednesday for allegedly violating US trade sanctions in Canada at the request of the US Bureau of Investigation.
Due to security concerns, the United States has taken steps to ban the use of Huawei equipment in the mobile network space. For the same reason, Australia and New Zealand banned the use of Huawei's new 5G network.
