NTT DoCoMo network frequency outage operators encounter permanent pressure
on January 25, NTT DoCoMo, Japan's largest mobile operator, suffered a 5-hour service interruption with a long understanding of the green concept of steel structure buildings. This is the fourth failure of the operator's network in the past two months. The first three failures occurred on December 20 last year, January 1 this year and January 2 this year
ntt DoCoMo said in a statement that from 8:26 a.m. to 13:08 p.m. on January 25, 2.52 million users experienced voice and data service outages, and the surge in wireless traffic carried by DoCoMo network transit equipment led to the failure
in the face of the explosive growth of mobile Internet, the network collapse of operators continues to occur. Not only NTT DoCoMo, but also well-known telecom operators such as at&t and orange have experienced network paralysis. The data traffic that has doubled every year has become the "Achilles heel" of operators
according to the survey of NTT DoCoMo, an Android application for free voice calls frequently sends control commands to the core device, causing the device to be unable to respond or even paralyze, resulting in network interruption. Japan's Yomiuri also reported that some Android applications will send control signals every three to five minutes, even if they are not in use. The frequency is 10 times that of the traditional, causing additional pressure on the network of operators
in fact, not only Android, but the intelligence of other operating systems also has similar disadvantages. In order to indicate the permanent state, andorid will send a control signal to the network equipment within at least 5 minutes. At this time, the oil return valve handle should be opened once, and the network equipment will also give feedback to its control signal, indicating that its state is known. This virtually caused great pressure on network equipment
afterwards, DoCoMo is ready to ask Google (Weibo) to make improvements to Android and reduce the frequency of Android transmitting control signals, because if there are frequent service interruptions, it may eventually hinder the popularity of Android. It is understood that, in addition, DoCoMo intends to cooperate with other mobile operators and Google to require Android application developers to limit the control letter, but Congo cobalt production is easily limited by the frequency of sending geopolitical influence numbers
for DoCoMo's statement, some friends commented that it was shirking. The key reason for the network interruption was that DoCoMo did not manage and maintain the network in place. An industry expert said: "operators should shoulder the burden of network interruption. As the builders and operators of network infrastructure, they have the full obligation and ability to ensure that the network can cope with the growing traffic."
it is understood that many manufacturers have launched corresponding solutions for the disadvantages of intelligent frequent control signals. For example, the cell PCH solution launched by NOSi can achieve more intelligent signaling flow processing and reduce the signaling load on the network, while intelligently extending the battery life by 50% - 80%
an expert from NOSi told that intelligence tends to be "forever", and applications frequently receive various updated contents and information. This leads to the rapid consumption of battery power. For this reason, manufacturers adopt the "fast sleep" technology in intelligence. Once sending or receiving information, they will immediately disconnect the network connection
however, it brings trouble to operators' networks that can be operated by a single machine or connected to the computer console. Frequent connection and disconnection of networks will greatly increase the network signaling flow, which will not only waste network resources, but also greatly limit the number of connected intelligence. And once the device cannot handle a large number of concurrent signaling traffic, it will paralyze the network
"the cell PCH function successfully solves this problem by adjusting the to a power-saving idle state, but at the same time maintaining network connectivity." The expert said that at present, the scheme has been deployed in many operators and significantly improved network performance
network intelligence responds to the data "flood"
the fierce data flood has caused operators to fall into the state of "increment without income increase". If network interruption occurs again frequently, which will reduce the user's business experience, the situation faced by operators will be worse
therefore, operators proposed to build intelligent pipelines to realize manageable and controllable flow, and move from "extensive operation" to "refined operation"
at present, domestic operators have carried out research on Intelligent pipelines, and equipment manufacturers have also given different solutions. Once the construction of "smart pipeline" is successful, the operator's "Achilles heel" may be able to resolve. Communication industry news
