Abstract
Description
Technical Field
[0001] The present invention relates to the field of 5G signal technology, and specifically to a method for reducing the power consumption of a 5G base station. Background Art
[0002] The fifth generation mobile communication technology (5G) is a new generation of broadband mobile communication technology with high speed, low latency and large connection characteristics. 5G communication facilities are the network infrastructure for realizing the interconnection of people, machines and things. In order to meet the diverse application scenario requirements of 5G, the key performance indicators of 5G are more diversified. ITU has defined eight key performance indicators of 5G, among which high speed, low latency and large connection are the most prominent features of 5G. The user experience rate reaches 1Gbps, the latency is as low as 1ms, and the user connection capacity reaches 1 million connections / square kilometer.
[0003] Compared with traditional 4G base stations, 5G base stations consume about 3 to 4 times more power than 4G base stations due to the large number of components deployed. High power consumption is a thorny issue for operators to deploy 5G on a large scale, and it is also the largest consumption point of operating costs for operators. Therefore, there are many energy-saving technologies available now, such as power amplifier voltage regulation, symbol shutdown, channel shutdown, cell shutdown, and deep sleep. However, these are energy-saving technologies at the base station level, but their implementation is still somewhat unsatisfactory, and they cannot control energy conservation based on the capacity, load, and traffic trends of the entire network. Summary of the invention
[0004] In order to solve the above problems, the present invention provides a method for reducing the power consumption of 5G base stations, including the following steps: S1. Configure the information of all adjacent base stations adjacent to the serving base station, and connect the serving base station to the 5G network; S2. Configure the measurement reporting event, and carry the threshold value; S3. Detect the signal quality of the serving base station; S4. Send an activation instruction to the adjacent base station, and detect the signal quality of all adjacent base stations; S5. Select the base station with the best signal quality, perform inter-station switching and switch the terminal to the base station; S6. After the switching is successful, the serving base station releases the terminal resources.
[0005] Furthermore, the step S3 includes the following sub-steps: when the signal quality of the serving base station is higher than or equal to a threshold value, repeating the step S3; when the signal quality of the serving base station is lower than the threshold value, triggering a measurement reporting message and executing the step S4.
[0006] Furthermore, a step is included: detecting the terminal location information after switching, and determining whether the location information is within the signal coverage of the serving base station.
[0007] Furthermore, the determination of whether the location information is within the signal coverage of the serving base station includes the following sub-steps: when the location information is within the signal coverage of the serving base station, the terminal resources are directly released; when the location information is not within the signal coverage of the serving base station, a timer is triggered, and when the timer expires, the serving base station and the adjacent base stations enter a deep sleep state.
[0008] Furthermore, the data information interaction interface between the serving base station and the neighboring base station in the steps S4-S6 is an XN interface.
[0009] Furthermore, a pre-step is also included: S0. Setting a base station response time threshold and a base station signal threshold.
[0010] The present invention provides a method for reducing the power consumption of a 5G base station, which has the following beneficial effects:
[0011] The present invention recognizes the current state of the network, and under the premise of ensuring network quality and user experience, achieves refined energy saving by timely shutting down some devices, cells, channels or power amplifiers, or improving cooling efficiency.

[0014] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.
[0015] The following is a detailed description of the implementation method of the present invention in conjunction with the accompanying drawings. Only some embodiments are described, not all embodiments. For the purpose of clarity, representations and descriptions that are not related to the present invention are omitted in the drawings and descriptions.
[0016] In order to have a clearer understanding of the technical features, purposes and beneficial effects of the present invention, the technical solution of the present invention is now described in detail below. Obviously, the implementation cases described are part of the embodiments of the present invention, not all of the embodiments, and cannot be understood as limiting the scope of the implementation of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.
[0017] like Figure 1 As shown, the present invention provides a method for reducing the power consumption of 5G base stations, including the following steps: S1. Configure information of all adjacent base stations adjacent to the serving base station, and connect the serving base station to the 5G network; S2. Configure measurement reporting events, and carry threshold values; S3. Detect the signal quality of the serving base station; S4. Send activation instructions to adjacent base stations, and detect the signal quality of all adjacent base stations; S5. Select the base station with the best signal quality, perform inter-station switching to switch the terminal to the base station; S6. After the switching is successful, the serving base station releases the terminal resources.
[0018] Among them, step S3 includes the following sub-steps: when the signal quality of the serving base station is higher than or equal to the threshold value, repeat step S3; when the signal quality of the serving base station is lower than the threshold value, trigger a measurement reporting message and execute step S4.
[0019] It also includes a step: detecting the terminal location information after switching, and determining whether the location information is within the signal coverage of the service base station: when the location information is within the signal coverage of the service base station, the terminal resources are directly released; when the location information is not within the signal coverage of the service base station, a timer is triggered, and when the timer times out, the service base station and the adjacent base stations both enter a deep sleep state.
[0020] The data information interaction interface between the serving base station and the neighboring base station in steps S4-S6 is an XN interface.
[0021] It also includes a pre-step: S0. Setting the base station response time threshold and the base station signal threshold.
[0022] Example:
[0023] The present invention provides a method for reducing the power consumption of 5G base stations, by referring to the principle of voice-controlled street lamps, the principle that the street lamps will only light up when people enter the range of the street lamps. When a 5G user attempts to enter another neighboring base station from a 5G base station, when the terminal measures that the signal quality of the service cell is lower than the specified threshold value, a measurement reporting event will be triggered. After the 5G base station receives the reporting event, the 5G base station actively sends a command to activate the cell to all pre-configured neighboring cells through the XN interface, so that the neighboring base stations around the service cell can be activated to enter the working state and accept the access cell of the 5G user. After the 5G user leaves the source cell, when the source cell reaches the set time threshold, the source cell begins to enter a deep sleep state, so that only the 5G base station cell where the terminal is located is in the working state, and the 5G base stations at other locations can enter the energy-saving state. This method is particularly suitable for remote areas with a small number of terminals but a large coverage area. In this way, the energy-saving consumption of the entire 5G network can be achieved.
[0024] Step 1: First, the service cell base station needs to pre-configure the information of all neighboring base stations, such as the IP address of the neighboring base station and the global unique number of the base station. When the base station is running, all base stations can be connected through the XN interface and send interactive messages through the XN interface. Then the terminal accesses the 5G network through the service base station at its location and is in a connected state.
[0025] Step 2: After the terminal successfully accesses the network, the serving base station sends a configuration measurement reporting event to the terminal, and carries a threshold value, instructing the terminal to report the event when the signal quality of the serving cell is lower than the threshold value.
[0026] Step 3: When the terminal detects that the signal quality of the serving base station is lower than the configured threshold, it triggers a measurement report message to notify the serving base station that the terminal is leaving the signal coverage of the serving base station.
[0027] Step 4: After receiving the measurement report message, the serving base station searches for all pre-configured neighboring base station information and sends a cell activation command to all neighboring base stations through the XN interface. After the neighboring base station receives the cell activation message on the XN interface, it enters the normal working state from the dormant energy-saving state and sends signals to serve the terminal access.
[0028] Step 5: When the terminal can receive the signal from the neighboring base station, it detects the signal quality of all neighboring base stations, selects the neighboring base station with the best signal quality as the target base station, and reports the number of the target base station with the best signal quality to the current serving base station.
[0029] Step 6: After the serving base station knows the target base station number, it initiates the inter-station switching process and switches the terminal to the target cell base station. After the switching is successful, the serving base station releases the terminal's resources.
[0030] Step 7: When there is no terminal in the cell signal coverage of the serving cell base station, a timer is triggered, and the duration is a preset time threshold. When the timer times out, the base station enters a deep sleep state, thereby entering an energy-saving state.
[0031] Step 8: The same is true for other adjacent base stations. When there is no terminal within the cell signal coverage, a timer is triggered. The duration is a preset time threshold. When the timer times out, the base station enters a deep sleep state, thereby entering an energy-saving state.
[0032] The present invention recognizes the current state of the network, and under the premise of ensuring network quality and user experience, achieves refined energy saving by timely shutting down some devices, cells, channels or power amplifiers, or improving cooling efficiency. It uses the existing network basic data and the built-in strategy algorithm to determine the configuration parameters of network energy saving, including the start-up strategy, related thresholds and time period settings, so as to achieve the goal of reducing the energy consumption of the existing network.

It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
