View the operation and management of Iot from an instance)

Before the concept of "Iot" was put forward, our company provided wireless, sgsn, ggsn, cmnet and other data transmission channels in our projects under the name of "industry applications, through these channels, application terminals can directly access the business platform. We can say that we are a "Blind Pipeline". We do not know much about the business in the pipeline and cannot control it.

Taking "vehicle positioning" as an example, we can clearly see that we only transmit data, whether it is a front-end vehicle or a back-end vehicle management system, our company is not aware of its operation status, and cannot achieve effective operation management. This situation often leads to a decline in passive maintenance and service quality.

At the beginning of last year, a company reported a problem: the ggsn device of the GPRS private network of our company was cut in the early morning and announced in the media in accordance with relevant telecommunications regulations. A gas company's gas valve remote control system runs through the GPRS private network provided by our company. The gas company did not know that our equipment should be adjusted, as a result, they cannot remotely control the switch of the gas valve when the equipment is cutover. Because they do not know in advance, the gas company has no emergency measures. At that time, the gas company was very nervous because the gas valve was not properly opened and may cause an accident. Their response was fierce.

We have considered this issue. Our current maintenance mode and network architecture are still based on the human behavior mode. For example, in the early hours of the morning, device cutover is performed when the business volume is low, device adjustments that affect the business are announced in the media three days in advance, and problems are collected by the customer by dialing 10086. These practices are based on "people" as the user of our network. As everyone knows, Iot applications tend to stay around the clock, such as gas valve control and police car scheduling. They often do not read media announcements or read, and do not know what impact they have on themselves; it is basically impossible to actively inform the operator about the network usage. Therefore, it is necessary to establish an effective Iot device networking structure, management system, and maintenance mechanism.

I personally think that two problems should be solved in network maintenance:

1. How can we organize the network structure to ensure that uninterrupted services will never stop? (It refers to the core network side, which cannot be guaranteed by the wireless side) such as remote control of air valves, police car scheduling, and some special applications required by national security. Therefore, we need to consider the proprietary ggsn of IOT, as well as backup among multiple devices and Disaster Tolerance Mechanisms.

2. How to quickly and effectively collect "things" awareness of our network. People may encounter 10086 million problems when using their services, and 10086 of Jiangsu currently has a leading group mechanism for fast collection and convergence of complaints. How can I effectively and quickly collect problems in Iot? Network indicators alone cannot fully reflect the use of end-to-end services. However, service consumers, such as system dispatchers, often block services when detecting problems, small quality declines cannot be detected in time.

I have recently considered many Iot problems and have also consulted the wmmp protocol proposed by our company. I was pleasantly surprised to find that these problems are already under consideration. Is China Mobile Iot application architecture:

We can see that, between the terminal and the application system, we have set up an "Operation Support System" to control the business operation process through the M2M platform, a key device for business operation and management, it also provides resource management and operation support for the Internet of Things private network. Through the construction of the operating platform, the technical advantages of operators can be leveraged, and the operation control, billing and service capabilities of Iot can be improved through the platform. Under the guidance of this idea, coupled with an effective and reasonable network equipment organizational structure, the problems I have raised can be solved smoothly.

In addition, I always think that the biggest advantage of a carrier is "platform". Here "platform" is a general concept, it includes transmission channels, billing, user management, and our offices all over the country. To put it bluntly, it is an almost ubiquitous access capability, this is also an exclusive advantage for companies such as Apple and Google. One day, small and medium-sized enterprises and even individual developers can use our public cloud service platform to develop their own Iot applications, put it into "mm" to create an app mall that surpasses the appstore! For myself, I hope to have an application to help me find glasses. I have attached a sensor to the glasses beforehand. When the glasses cannot be found, I hold my cell phone, according to the tone, the intensity gradually approaches it. Hope that the dream will come true.
