[0041] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

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

[0043] When there are multiple layers of frequency coverage in a wireless network, energy-saving strategies can be planned according to the coverage characteristics of different frequencies, providing frequency cells with continuous coverage as basic coverage cells, and cells with enhanced capacity in hot spots as energy-saving cells. Basic coverage cells can completely cover the coverage area of ​​energy-saving cells. Usually, when the load of energy-saving cells is low and the load of basic coverage cells is low enough to take over the original user load of energy-saving cells, users in energy-saving cells are migrated to basic coverage cells, and energy-saving cells are closed to achieve energy-saving effects.

[0044] After the energy-saving cell enters the energy-saving state, when the user load of the basic coverage cell continues to increase and exceeds the load threshold of the basic coverage cell, the basic coverage cell can wake up the energy-saving cell to share the user load.

[0045] Figure 1 is a schematic diagram of an existing cell shutdown energy saving according to an embodiment of the present invention, referring to Figure 1 In the existing cell shutdown energy-saving technology, energy-saving cell shutdown requires shutting down the energy-saving cell to achieve energy-saving effects, that is, the energy-saving cell is without service. In business scenarios, cell shutdown energy saving is only suitable for scenarios where the user tidal pattern is very stable, and is a semi-static energy-saving method. When the user activity patterns of the energy-saving cell or its basic coverage cell are relatively complex and changeable, this method is difficult to take into account both energy-saving effects and user experience. There are the following problems:

[0046] 1) Since there is no service in the energy-saving cell after entering the energy-saving state, users in the energy-saving cell will drop calls when entering the energy-saving state, or users need to be forced to migrate to the basic coverage cell before entering the energy-saving state. Both actions will cause the user experience to deteriorate. After the load of the basic coverage cell increases, the energy-saving cell must be activated to share the user load of the basic coverage cell. Before the activation is completed, the user experience of the basic coverage cell is also affected by the high load.

[0047] 2) It is impossible to dynamically strike a balance between energy-saving effects and user experience, and there is no trade-off mechanism between user experience and energy-saving effects.

[0048] The technical concept of this embodiment is that, in the dynamic shutdown energy-saving time period, when it is monitored that 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, the auxiliary carrier of the energy-saving cell is added for the UE in the basic coverage cell, and the load of the basic coverage cell of the UE is diverted to the auxiliary carrier of the energy-saving cell of the UE, so as to achieve a balance between energy-saving effect and user experience, and achieve energy-saving effect as much as possible while ensuring user experience, which solves the problem that the cell shutdown energy-saving technology in the related technology is difficult to take into account both energy-saving effect and user experience.

[0049] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 2 1 is a hardware structure block diagram of a mobile terminal according to an energy saving method of a wireless network according to an embodiment of the present invention. Figure 2 As shown, the mobile terminal may include one or more ( Figure 2 Only one is shown in the figure) a processor 202 (the processor 202 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 204 for storing data, wherein the mobile terminal may also include a transmission device 206 and an input / output device 208 for communication functions. It can be understood by those skilled in the art that Figure 2 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 2 More or fewer components as shown, or with Figure 2 Different configurations shown.

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

[0051] The transmission device 206 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 206 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 206 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0052] In this embodiment, a wireless network energy saving method is provided. Figure 3 is a flow chart of a method for energy saving in a wireless network according to an embodiment of the present invention. Figure 3As shown, the process includes the following steps:

[0053] Step S301, in a dynamic shutdown energy-saving time period, controlling an energy-saving cell to enter a dynamic shutdown energy-saving state, and notifying a basic coverage cell that the energy-saving cell has entered a dynamic shutdown energy-saving state, wherein the basic coverage cell completely covers the energy-saving cell.

[0054] The embodiment of the present invention can be applied to a wireless access network, where there is multi-frequency coverage (greater than or equal to 2 layers, the frequency can be 4G or 5G frequency). In a multi-layer network coverage scenario, the dynamic shutdown energy saving time can be increased.

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

[0056] As an example, in the dynamic shutdown energy-saving time period, the base station can 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. The basic coverage cell can completely cover the energy-saving cell.

[0057] As an example, the energy-saving cell in the network and the basic coverage cell that completely covers the energy-saving cell may be grouped into an energy-saving cell group.

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

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

[0060] As an example, the base station may collect the historical load of the energy-saving cell within a preset time period and the historical user rate data corresponding to the historical load of the energy-saving cell. For example, the historical load of the energy-saving cell within 24 hours of a day and the historical user rate data corresponding to the historical load may be collected.

[0061] Step S3002: determining a historical load corresponding to a maximum historical user rate data according to a historical load of the energy-saving cell within a preset time period and historical user rate data corresponding to the historical load.

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

[0063] For example, a coordinate image can be established with the historical load of the energy-saving cell in a preset time period as the horizontal coordinate and the historical user rate data corresponding to the historical load as the vertical coordinate, so as to find the horizontal coordinate corresponding to the highest point, that 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 cell.

[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 cell. Among them, a load less than or equal to the load threshold of the energy-saving cell indicates that the user rate is not affected by the load, and a load greater than the load threshold of the energy-saving cell indicates that the user rate is affected by the load, that is, the user experience is deteriorated and the load needs to be shared.

[0066] For example, a relationship model between the cell experience index and the cell load can also be constructed. According to the cell experience-load relationship model, data analysis is performed on all cells of energy-saving frequencies (frequencies that provide hotspot coverage) and coverage frequencies (frequencies that provide continuous coverage) in the network. Cells with energy-saving frequencies and coverage frequencies whose overlapping coverage meets the overlapping coverage threshold, as well as cells with energy-saving frequencies and coverage frequencies whose load rules meet the preset load conditions, are selected to perform energy-saving relationship pairing, and select a time period for dynamically shutting down energy saving for the energy-saving cells.

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

[0068] As an example, the time period corresponding to when the historical load of the energy-saving cell is lower than the load threshold of the energy-saving cell may be determined as the dynamic shutdown energy-saving time period.

[0069] As an example, during this period, the overall load can be shared between the energy-saving cell and the basic coverage cell through the main carrier and / or auxiliary carrier of the user's carrier aggregation (CA), while maintaining the user experience of the energy-saving cell and the basic coverage cell.

[0070] It should be noted that the dynamic shutdown energy-saving time period refers to the time period during which energy-saving condition detection can be performed and energy-saving related operations can be performed when the energy-saving conditions are met. It does not mean that the energy-saving effect can be achieved in this time period.

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

[0072] New UEs are prohibited from initially accessing or switching 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 the energy-saving cell enters the dynamic shutdown energy-saving state, the energy-saving cell denies access to all UEs, and at the same time turns on symbol shutdown of radio frequency equipment in the energy-saving cell.

[0074] For example, when the time enters the dynamic shutdown energy-saving period, the energy-saving cell sets the bar field in the cell broadcast information to prohibit new UEs from initial access, or rejects all UE requests to switch to the energy-saving cell, so that the UE cannot access the energy-saving cell. At the same time, the symbol-level shutdown of the RF device is turned on in the energy-saving cell.

[0075] It should be noted that the symbol-level shutdown technology of the RF device can immediately shut down the RF device when there is no data transmission, and immediately turn on the RF device when there is data transmission. When the RF device is turned off, energy saving can be achieved. The lower the load, the more time there is no data transmission, and the better the energy 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 time 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 for the UE in the cell, and the UE data load can be diverted 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 auxiliary carrier of the energy-saving cell for the user equipment UE in the basic coverage cell, and divert the load of the basic coverage cell of the UE to the auxiliary carrier of the energy-saving cell of the UE.

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

[0080] As an example, 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, the auxiliary carrier of the energy-saving cell is added for the user equipment UE in the basic coverage cell, and the load of the basic coverage cell of the UE is diverted to the auxiliary carrier of the energy-saving cell of the UE. At this time, the load of the basic coverage cell is shared by the energy-saving cell, the load of the energy-saving cell increases, and the energy-saving effect is weakened. At the same time, the load of the basic coverage cell is reduced to below the load threshold of the basic coverage cell, and the user rate is guaranteed.

[0081] In an optional embodiment, after adding the secondary carrier of the energy-saving cell for the user equipment UE in the basic coverage cell and diverting the load of the basic coverage cell of the UE to the secondary carrier of the energy-saving cell of the UE, it also includes: when the load of the basic coverage cell is lower than or equal to the load threshold of the basic coverage cell, stop adding the secondary carrier of the energy-saving cell for the user terminal in the basic coverage cell, and stop diverting the load of the basic coverage cell of the UE to the secondary carrier of the energy-saving cell of the UE.

[0082] As an example, when the load of the basic coverage cell is lower than the load threshold of the basic coverage cell, the basic coverage cell can stop adding auxiliary carriers in the energy-saving cell for UEs in the cell, and stop diverting the load of the basic coverage cell of the UE to the auxiliary carrier of the energy-saving cell of the UE, and the UE that has added the auxiliary carrier remains unchanged. Since the load of the basic coverage cell is lower than the load threshold of the basic coverage cell, the user rate in 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 of the energy-saving cell, increase the time when the energy-saving cell has no data to send, and increase the energy-saving effect.

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

[0084] In an optional embodiment, 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, the auxiliary carrier of the energy-saving cell is added to the user equipment UE in the basic coverage cell, and the load of the basic coverage cell of the UE is diverted to the auxiliary carrier of the energy-saving cell of the UE, and also 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, the energy-saving cell is controlled to exit the dynamic shutdown energy-saving state, and a message of the energy-saving cell exiting the dynamic shutdown energy-saving state is sent to the basic coverage cell.

[0085] As an example, during the dynamic shutdown energy-saving time 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 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 energy-saving cell is notified to exit the dynamic shutdown energy-saving state. Because the loads of the energy-saving cell and the basic coverage cell are already high at this time, it is impossible to dynamically adjust between cells by means of auxiliary carriers, and it is impossible to achieve a balance between energy-saving effects and user rates.

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

[0087] In the embodiment of the present invention, during the dynamic shutdown energy-saving time 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, the auxiliary carrier of the energy-saving cell is added to the user equipment UE in the basic coverage cell, and the load of the basic coverage cell of the UE is diverted to the auxiliary carrier of the energy-saving cell of the UE. In this way, a balance can be achieved between energy-saving effect and user experience, and energy-saving effect can be achieved as much as possible while ensuring user experience, which solves the problem that the cell shutdown energy-saving technology in the related technology is difficult to take into account both energy-saving effect and user experience.

[0088] The execution subject of the above steps may be a base station, a terminal, etc., but is not limited thereto.

[0089] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.
