Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a discontinuous reception parameter control energy-saving method for a power virtual private network. Background Art

[0002] In the 5G power virtual private network, terminal energy-saving technology is particularly important. With the widespread application of 5G technology, a large number of terminal devices in the power system, such as smart meters, sensors, and distribution controllers, have dramatically increased the number of devices connected to the network. These terminal devices need to run continuously for a long time to ensure real-time monitoring and data transmission of the power system, but since these devices are usually deployed in remote areas or environments where frequent maintenance is difficult, how to extend the service life of the equipment through efficient energy-saving technology has become an urgent problem to be solved.

[0003] The traditional terminal communication mode adopts a continuous reception method, which causes the terminal to maintain high energy consumption when there is no data transmission, and cannot effectively adapt to the complex business scenarios and irregular data traffic in the 5G network. The diverse needs of 5G networks, such as remote fault detection, intelligent scheduling and automatic control, have put forward higher requirements on the latency and power consumption of terminals. In some mission-critical scenarios, excessive latency may cause system failures, while excessive power consumption will shorten the service life of the equipment and increase maintenance costs. Therefore, how to dynamically adjust the energy consumption of terminal equipment in different network scenarios has become one of the technical problems that need to be solved in 5G power virtual private networks.

[0004] To this end, the existing technology has gradually introduced discontinuous reception (DRX) technology, which aims to reduce the energy consumption of the terminal through a periodic sleep and wake-up mechanism. However, the existing DRX mechanism has many shortcomings. First, the DRX mechanism is usually designed based on a fixed cycle and lacks the ability to flexibly respond to the actual network status and traffic demand. In the 5G power virtual private network, business traffic is often irregular, and different application scenarios have different requirements for terminal latency and power consumption. For example, tasks such as remote fault detection and automated control are very sensitive to latency, while applications such as narrowband Internet of Things (NB-IoT) have more stringent requirements on energy consumption. The existing fixed DRX cycle cannot adapt to these complex application scenarios, which may result in excessive latency or excessive power consumption, making it difficult to flexibly balance the energy efficiency and latency of the terminal in different scenarios.

[0005] In addition, traditional energy-saving mechanisms usually do not fully consider the impact of multi-user access and channel changes. In the 5G power virtual private network, multiple terminal devices access the network at the same time, facing a complex wireless channel environment. Since the receiving environment and communication load of the terminal device change over time, the existing fixed DRX cycle may not be able to effectively respond to network changes in some scenarios. For example, when the network load is low, the terminal device still maintains a high activation state, thereby wasting energy; when the network load is high, the fixed sleep mechanism may delay the reception of critical data packets, affecting the real-time and reliability of the task.

[0006] In terms of the technical path to meet the energy-saving needs of terminals, most of the existing energy-saving solutions adopt static strategies, lack the ability to adapt to complex dynamic network environments, and are difficult to meet the increasingly diverse business needs in 5G power virtual private networks. Especially in smart grids, the distribution of equipment is wide, the business scenarios are complex and changeable, and the dynamic and diverse business models require terminal devices to be able to adjust DRX parameters according to actual conditions to better optimize energy efficiency. This makes the existing energy-saving technologies show great limitations in dealing with the balance between power consumption and latency of terminal devices. Summary of the invention
