[0036] During the dynamic shutdown energy-saving period, when the load of the basic coverage cell is detected to be higher than the load threshold of the basic coverage cell and the load of the energy-saving cell is lower than the load threshold of the energy-saving cell, the present invention adds a secondary carrier of the energy-saving cell to the UE in the basic coverage cell and diverts the load of the UE's basic coverage cell to the secondary carrier of the UE's energy-saving cell. This achieves a balance between energy saving effect and user experience, and maximizes energy saving effect while ensuring user experience.

[0040] Figure 4 This is a structural block diagram of an energy-saving device for a wireless network according to an embodiment of the present invention. Detailed Implementation

[0041] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0042] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0043] When multiple frequency coverage layers exist in a wireless network, energy-saving strategies can be planned according to the coverage characteristics of different frequency points. Continuously covered frequency cells can be provided as basic coverage cells, while cells with enhanced capacity in hotspot areas can be designated as energy-saving cells. The basic coverage cell can completely cover the coverage area of ​​the energy-saving cell. Typically, when the load on the energy-saving cell is low, and the load on the basic coverage cell is also low enough to handle the existing user load of the energy-saving cell, users in the energy-saving cell are migrated to the basic coverage cell, and the energy-saving cell is shut down to achieve energy savings.

[0044] Once an energy-saving community enters energy-saving mode, when the user load of the basic coverage community continues to rise and exceeds the load threshold of the basic coverage community, the basic coverage community can activate the energy-saving community to share the user load.

[0045] Figure 1 This is a schematic diagram of energy saving during a conventional cell shutdown according to an embodiment of the present invention, with reference to... Figure 1 In existing cell shutdown energy-saving technologies, energy-saving cell shutdown requires shutting down the energy-saving cell to achieve the energy-saving effect, meaning the energy-saving cell is without service. In terms of business scenarios, cell shutdown energy saving is only suitable for scenarios with very stable user activity patterns, making it a semi-static energy-saving method. When the user activity patterns in the energy-saving cell or its underlying coverage area are complex and variable, this method struggles to balance energy saving and user experience. The following problems exist:

[0046] 1) Since there is no service when an energy-saving cell enters energy-saving mode, users in the energy-saving cell may experience dropped calls during the energy-saving process, or users may need to be forcibly migrated to the basic coverage cell before entering energy-saving mode. Both of these actions will result in a deterioration in user experience. After the load on the basic coverage cell increases, the load on users in the basic coverage cell can only be shared after the energy-saving cell is activated. Before the activation is completed, the user experience in the basic coverage cell is also affected by the high load.

[0047] 2) It cannot dynamically balance energy saving effect and user experience, and there is no trade-off mechanism between user experience and energy saving effect.

[0048] The technical concept of this embodiment is that, during the dynamic shutdown energy-saving period, when the load of the basic coverage cell is detected to be higher than the load threshold of the basic coverage cell and the load of the energy-saving cell is lower than the load threshold of the energy-saving cell, an auxiliary carrier of the energy-saving cell is added to the UE in the basic coverage cell, and the load of the UE's basic coverage cell is diverted to the auxiliary carrier of the UE's energy-saving cell. This achieves a balance between energy saving effect and user experience, and maximizes energy saving effect while ensuring user experience. This solves the problem that cell shutdown energy-saving technology in related technologies is difficult to balance energy saving effect and user experience.

[0049] The methods and embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, Figure 2 This is a hardware structure block diagram of a mobile terminal according to an embodiment of the energy-saving method for wireless networks based on an embodiment of the present invention. Figure 2 As shown, a mobile terminal may include one or more ( Figure 2 Only one is shown in the diagram. A processor 202 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 204 for storing data are also shown. The mobile terminal may further include a transmission device 206 for communication functions and an input / output device 208. Those skilled in the art will understand that... Figure 2 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 2 The more or fewer components shown, or having the same Figure 2 The different configurations shown.

[0050] The memory 204 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the energy-saving method for wireless networks in this embodiment of the invention. The processor 202 executes various functional applications and data processing by running the computer program stored in the memory 204, thereby implementing the aforementioned method. The memory 204 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 204 may further include memory remotely located relative to the processor 202, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0051] The transmission device 206 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device 206 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 206 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

[0052] This embodiment provides an energy-saving method for wireless networks. Figure 3 This is a flowchart of a wireless network energy-saving method according to an embodiment of the present invention, such as... Figure 3As shown, the process includes the following steps:

[0053] Step S301: During the dynamic shutdown energy-saving period, control the energy-saving cell to enter the dynamic shutdown energy-saving state, and notify the basic coverage cell that the energy-saving cell has entered the dynamic shutdown energy-saving state, wherein the basic coverage cell completely covers the energy-saving cell.

[0054] This invention can be applied to wireless access networks with multi-frequency coverage (at least two layers, and the frequencies can be 4G or 5G). It can increase dynamic shutdown and energy-saving time in multi-layer network coverage scenarios.

[0055] As an example, an energy-saving cell can refer to a cell at the capacity layer frequency, and the energy-saving cell can be completely covered by one or more cells at the coverage layer frequency. A basic coverage cell can refer to a cell at the coverage layer frequency, wherein the coverage area of ​​one or more cells can completely cover the energy-saving cell.

[0056] As an example, during a dynamic power-saving shutdown period, the base station can control the energy-saving cell to enter a dynamic power-saving shutdown state and notify the basic coverage cell that the energy-saving cell has entered a dynamic power-saving shutdown state. The basic coverage cell can completely cover the energy-saving cell.

[0057] As an example, an energy-saving cell group can be formed by combining an energy-saving cell in the network with a basic coverage cell that fully covers the energy-saving cell.

[0058] In an optional embodiment, prior to the dynamic shutdown energy-saving period, the method further includes:

[0059] Step S3001: Collect historical load data of the energy-saving community and historical user rate data corresponding to the historical load within a preset time period.

[0060] As an example, a base station can collect historical load data of energy-saving cells and corresponding historical user rate data within a preset time period. For instance, it can collect historical load data of energy-saving cells and corresponding historical user rate data within a 24-hour period.

[0061] Step S3002: Based on the historical load of the energy-saving community within a preset time period and the historical user rate data corresponding to the historical load, determine the historical load corresponding to the maximum historical user rate data.

[0062] As an example, the historical load corresponding to the maximum historical user rate can be determined based on the historical load of the energy-saving community within a preset time period and the historical user rate data corresponding to the historical load.

[0063] For example, a coordinate graph can be established by using the historical load of the energy-saving community within a preset time period as the x-axis and the historical user rate data corresponding to the historical load as the y-axis, thereby finding the x-axis corresponding to the highest point, which is the historical load corresponding to the maximum historical user rate data.

[0064] Step S3003: Determine the historical load corresponding to the maximum historical user rate data as the load threshold of the energy-saving community.

[0065] As an example, the historical load corresponding to the maximum historical user rate data can be determined as the load threshold of the energy-saving community. Loads less than or equal to the load threshold of the energy-saving community indicate that the user rate is not affected by the load, while loads greater than the load threshold indicate that the user rate is affected by the load, meaning the user experience deteriorates, and the load needs to be distributed.

[0066] For example, a relationship model between the experience index and the load of a cell can be constructed. Based on the experience-load relationship model, data analysis can be performed on all cells in the network that are energy-saving frequency points (frequency points that provide hotspot coverage) and coverage frequency points (frequency points that provide continuous coverage). Cells with energy-saving frequency points and coverage frequency points whose cell overlap coverage meets the overlap coverage threshold, as well as cells with energy-saving frequency points and coverage frequency points whose load patterns meet the preset load conditions, can be selected for energy-saving cell dynamic shutdown time periods.

[0067] In an optional embodiment, the method further includes: determining the time period corresponding to the period when the historical load of the energy-saving community is lower than the load threshold of the energy-saving community as the dynamic shutdown energy-saving time period.

[0068] As an example, the time period corresponding to the historical load of the energy-saving community being lower than the load threshold of the energy-saving community can be determined as the dynamic shutdown energy-saving period.

[0069] As an example, during this period, the overall load can be distributed between energy-efficient cells and basic coverage cells through the primary and / or secondary carriers of the user's carrier aggregation (CA), thus ensuring the user experience of energy-efficient cells and basic coverage cells.

[0070] It should be noted that the dynamic shutdown energy-saving period refers to the period during which energy-saving conditions can be detected and energy-saving operations can be performed when the conditions are met. It does not mean that energy-saving effects will definitely be achieved during this period.

[0071] In an optional embodiment, after controlling the energy-saving cell to enter a dynamic shutdown energy-saving state, the method further includes:

[0072] New UEs are prohibited from initial access or handover to the energy-saving cell, and symbol-level shutdown of radio frequency devices is enabled in the energy-saving cell.

[0073] As an example, after an energy-saving cell enters a dynamic shutdown energy-saving state, the energy-saving cell rejects all UE access and simultaneously enables radio frequency equipment symbol shutdown in the energy-saving cell.

[0074] For example, after the time enters the dynamic power-saving shutdown period, the power-saving cell sets the bar field in the cell broadcast information to prohibit new UEs from initial access, or rejects all UE requests to hand over to the power-saving cell, making it impossible for UEs to access the power-saving cell. At the same time, symbol-level shutdown of radio frequency devices is enabled in the power-saving cell.

[0075] It should be noted that symbol-level shutdown technology for radio frequency (RF) devices can immediately shut down the RF device when there is no data transmission and immediately turn it on when data transmission occurs. Power saving is achieved when the RF device is off; the lower the load and the more times there are no data transmissions, the better the power saving effect.

[0076] Step S302: Monitor the load changes of the basic coverage cell and the energy-saving cell.

[0077] As an example, during the dynamic shutdown energy-saving period, the load and user experience indicators (i.e., user rate data) of the basic coverage cell can be monitored in real time so that when the load is too high, a secondary carrier in the energy-saving cell can be added to the UE in the cell, and the UE data load can be offloaded to the UE's secondary carrier to adjust the load.

[0078] Step S303: When the load of the basic coverage cell is higher than the load threshold of the basic coverage cell and the load of the energy-saving cell is lower than the load threshold of the energy-saving cell, add the secondary carrier of the energy-saving cell to the user equipment (UE) in the basic coverage cell, and divert the load of the UE's basic coverage cell to the secondary carrier of the energy-saving cell of the UE.

[0079] As an example, historical load data of basic coverage cells and historical user rate data corresponding to the historical load of basic coverage cells can be collected within a preset time period. Based on the historical load data of basic coverage cells and historical user rate data corresponding to the historical load of basic coverage cells within the preset time period, the historical load corresponding to the maximum historical user rate data of basic coverage cells can be determined. The historical load corresponding to the maximum historical user rate data of basic coverage cells can be determined as the load threshold of basic coverage cells.

[0080] As an example, when the load of the basic coverage cell exceeds its load threshold and the load of the energy-saving cell is below its load threshold, a secondary carrier of the energy-saving cell is added to the user equipment (UE) within the basic coverage cell, and the load of the UE's basic coverage cell is offloaded to the secondary carrier of the energy-saving cell. In this case, because the load of the basic coverage cell is offloaded to the energy-saving cell, the load of the energy-saving cell increases, reducing the energy-saving effect. Simultaneously, the load of the basic coverage cell decreases below its load threshold, ensuring the user's data rate.

[0081] In an optional embodiment, after adding the secondary carrier of the energy-saving cell to the user equipment (UE) within the basic coverage cell and offloading the load of the UE's basic coverage cell to the secondary carrier of the energy-saving cell, the method further includes: when the load of the basic coverage cell is lower than or equal to the load threshold of the basic coverage cell, stopping the addition of the secondary carrier of the energy-saving cell to the user terminal within the basic coverage cell and stopping the offloading of the load of the UE's basic coverage cell to the secondary carrier of the energy-saving cell.

[0082] As an example, when the load of the basic coverage cell is lower than its load threshold, the basic coverage cell can stop adding secondary carriers to the energy-saving cell for UEs within the cell and stop offloading the load of the UE's basic coverage cell to the secondary carrier of the UE's energy-saving cell. UEs that have already had secondary carriers added remain unchanged. Since the load of the basic coverage cell is lower than its load threshold, the user rate within the cell will not be affected by the load. At the same time, stopping the migration of load to the energy-saving cell can reduce the load on the energy-saving cell, increase the time when the energy-saving cell has no data transmission, and increase the energy-saving effect.

[0083] As an example, during the dynamic shutdown energy-saving period, the base station can monitor the load changes of the energy-saving cell and the basic coverage cell in real time. Based on the load changes of the energy-saving cell and the basic coverage cell, it can control the addition of secondary carriers in the energy-saving cell and the load diversion of the basic coverage cell, dynamically adjusting between energy-saving effect and user rate, and achieving energy-saving effect as much as possible while ensuring user rate experience.

[0084] In an optional embodiment, the step of adding a secondary carrier of the energy-saving cell to the user equipment (UE) in the basic coverage cell and diverting the load of the UE's basic coverage cell to the secondary carrier of the energy-saving cell when the load of the basic coverage cell is higher than the load threshold of the basic coverage cell and the load of the energy-saving cell is lower than the load threshold of the energy-saving cell, further includes: when the load of the basic coverage cell is higher than the load threshold of the coverage cell and the load of the energy-saving cell is higher than the load threshold of the energy-saving cell, after a preset time period, controlling the energy-saving cell to exit the dynamic power-off energy-saving state, and sending a message that the energy-saving cell has exited the dynamic power-off energy-saving state to the basic coverage cell.

[0085] As an example, during the dynamic shutdown energy-saving period, when the load of the basic coverage cell exceeds the load threshold of the coverage cell, and the load of the energy-saving cell also exceeds the load threshold of the energy-saving cell, the energy-saving cell can be controlled to exit the dynamic shutdown energy-saving state after a preset time period, and the basic coverage cell can be notified to exit the dynamic shutdown energy-saving state. This is because at this time, the loads of both the energy-saving cell and the basic coverage cell are already high, making it impossible to dynamically adjust between cells using auxiliary carriers, thus failing to achieve a balance between energy saving and user rate.

[0086] As an example, when the dynamic shutdown energy-saving period ends, the energy-saving cell can be controlled to exit the dynamic shutdown energy-saving state and the covered cells can be notified that the energy-saving cell has exited the dynamic shutdown energy-saving state.

[0087] In this embodiment of the invention, during the dynamic shutdown energy-saving period, the energy-saving cell is controlled to enter the dynamic shutdown energy-saving state, and the basic coverage cell is notified that the energy-saving cell has entered the dynamic shutdown energy-saving state, wherein the basic coverage cell completely covers the energy-saving cell; the load changes of the basic coverage cell and the energy-saving cell are monitored in real time; when the load of the basic coverage cell is higher than the load threshold of the basic coverage cell, and the load of the energy-saving cell is lower than the load threshold of the energy-saving cell, a secondary carrier of the energy-saving cell is added to the user equipment (UE) in the basic coverage cell, and the load of the UE's basic coverage cell is diverted to the secondary carrier of the energy-saving cell of the UE. This achieves a balance between energy saving effect and user experience, maximizing energy saving effect while ensuring user experience, and solves the problem that cell shutdown energy-saving technology in related technologies struggles to balance energy saving effect and user experience.
