New Solution for LTE Networks"

Mobile, broadband, and IP-based telecommunication services are becoming increasingly apparent. mobile communication technology is in a critical period of network technology evolution. As a unified standard for next-generation mobile communication, the LTE system has many advantages, including high-frequency spectral efficiency, peak rate, high mobility, and flattened network architecture. This efficient network system not only brings us good network awareness, but also brings us thinking about the way we work through its running mode.

OFDM-firewood

OFDM, or orthogonal frequency division multiplexing technology, is one of the key technologies of LTE. It uses multiple frequencies for parallel transmission to achieve broadband transmission. Each sub-carrier overlaps with each other and is orthogonal to each other, this greatly improves the spectrum efficiency. For work, "1 + 1> 2" efficient collaboration. The stream can only emit a small wave of waves to make the sea burst into waves. Individuals are for the team, just as the stream is for the sea. Everyone has their own advantages and shortcomings. Although diligent, it is not so easy to ask everyone to do this. In a team, using the knowledge and skills of each member to work together and give full play to their personal advantages, this team will be extremely powerful.

Scheduling algorithm-Team Incentive Mechanism

In LTE, scheduling refers to allocating time slot resources for upstream and downstream links. The basic goal is to use different channel quality and other conditions between different UE while QoS is met, maximize system capacity as much as possible. The proportional fairness algorithm comprehensively considers the capacity of the residential area and the QoS of the user's business, and considers the fairness of the scheduling user. Every team's work requires reasonable scheduling of every talent to achieve the best results and the greatest success. There are two main scheduling methods for team members: punishment and encouragement. Moderate punishments and incentives are positive and can continuously improve efficiency. Excessive punishment is ineffective. A member who is often denied does not have much enthusiasm for work. Only reasonable scheduling can make the team members respond to each other and cooperate with each other in an orderly manner.

Signaling process-efficient and concise management process

Each signaling line in the LTE system is equivalent to a 2G or 3G system ~ Three signaling entries. In particular, the event reporting method of this system is different from that of 2G and 3G. In the LTE system, events are triggered and reported, and then converted to periodic reporting. This method can effectively prevent the impact caused by report loss or internal process failure, and also play a retry role. More importantly, an event report may not contain all the content, you can get more complete results by switching the event cycle.

For management, this mechanism is worth consideration and reference. The achievement of each command and task directly determines the efficiency. Focusing on the key points and the key points, we must be able to achieve half of the problem. However, the "event-to-Cycle" reporting method can be introduced into the daily work report, taking into account the comprehensive content and the concise process.

Network Architecture-flat architecture reduces "latency"

The biggest feature of the LTE network architecture is "flattening ". The reduction of the network level directly guarantees the latency requirements of LTE (the control plane latency is less than 100 ms, and the user plane latency is less than 10 ms ). This can also be introduced into the organizational structure of our daily work, reducing nodes, making communication smoother, and reducing the "latency" of our work.
