Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a method, apparatus, device, and readable storage medium for waking up an energy-saving cell. Background Technology

[0002] With the deployment of 5G networks and the continuous expansion of network scale, the energy demand of various communication devices is increasing, leading to higher energy consumption in communication networks. Furthermore, the transition from 4G to 5G has brought about significant changes in mobile communication technologies and products. 5G base stations support greater bandwidth, more channels, and more complex air interface protocols, resulting in higher hardware processing capabilities and significantly increased power consumption compared to 4G base stations, posing new challenges to energy conservation in wireless networks.

[0003] To reduce the energy consumption of wireless networks, various energy-saving technologies have been proposed in the industry. One such technology is cell shutdown technology, which leverages the tidal effect of existing network services. When the cell's service load is low, some hardware resources of the base station where the cell is located are shut down, putting the cell into a shutdown state. Once the energy-saving cell is in shutdown mode, neighboring cells in the same area determine the wake-up time of the energy-saving cell based on their own service load. When the service load of a neighboring cell exceeds a preset threshold, the energy-saving cell is woken up and put into operation. However, because the signal coverage areas of neighboring cells and energy-saving cells cannot completely overlap in actual networks, the service load of neighboring cells cannot accurately reflect the service demand under the energy-saving cell, resulting in an inaccurate wake-up time for the energy-saving cell, which cannot match the actual service demand of the energy-saving cell.

[0004] Another energy-saving technology proposed by the industry is timed wake-up technology. According to the preset shutdown and wake-up times, the energy-saving community enters the shutdown state and the working state at the specified time. However, the shutdown and wake-up times are statically configured and cannot dynamically adapt to the changes in the business needs of the energy-saving community. Summary of the Invention

[0005] This application provides a method, apparatus, device, and readable storage medium for waking up an energy-saving community, which solves the problem that the prior art does not determine the wake-up time of the energy-saving community based on the actual business needs of the community, resulting in the waste of resources in the energy-saving community.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] Firstly, this application provides a wake-up method for energy-saving communities, applicable to energy-saving communities, comprising:

[0008] The energy-saving cell receives probe signals sent by the target terminal. The target terminal includes one or more of the following: a terminal that has received an access failure indication message, or a terminal that has received a migration indication message sent by its current serving cell. The access failure indication message and the migration indication message are used to instruct the target terminal to identify the energy-saving cell and send probe signals to it. Based on the probe signals, the energy-saving cell determines its wake-up time. At the wake-up time, the energy-saving cell enters its working state and connects to the target terminal.

[0009] The wake-up method for energy-saving cells provided in this application involves the energy-saving cell receiving a detection signal from a target terminal, determining its wake-up time based on the signal, and then entering a working state and connecting to the target terminal at that wake-up time. This application utilizes the target terminal's detection signal to match the wake-up time of the energy-saving cell with its actual service needs, thereby improving the accuracy of the wake-up time and enabling on-demand wake-up of the energy-saving cell, balancing energy saving and service performance.

[0010] One possible implementation involves the detection signal including: detection signal power and detection period. The energy-saving cell determines its wake-up time based on the detection signal, including:

[0011] If the energy-saving community detects that the power of the detection signal exceeds a power threshold within a detection period during the monitoring cycle, the detection period is determined as the target period. The monitoring cycle includes multiple detection periods. If the number of target periods detected by the energy-saving community within the monitoring cycle exceeds a number threshold, the end time of the monitoring cycle is determined as the wake-up time of the energy-saving community.

[0012] Secondly, this application provides a wake-up method for energy-saving cells, applied to a target terminal, comprising: the target terminal determining the energy-saving cell corresponding to the target terminal based on cell information. The cell information includes one or more of the following: preset associated cell information, historical access information of the target terminal, and migration indication messages sent by the target terminal's current serving cell. The target terminal sends a probe signal to the energy-saving cell according to a target power.

[0013] The wake-up method for energy-saving cells provided in this application involves a target terminal determining the corresponding energy-saving cell based on cell information, and then sending a probe signal to the energy-saving cell according to the target power. By sending the probe signal to the energy-saving cell, the target terminal can enable the energy-saving cell to match its wake-up time with its actual service needs, thereby improving the accuracy of the wake-up time and achieving on-demand wake-up of the energy-saving cell, thus balancing energy saving and service performance.

[0014] One possible implementation involves using pre-defined associated cell information. This associated cell information includes one or more of the following: the identifier of the associated cell and the location information of the base station where the associated cell is located. The target terminal determines the energy-saving cell corresponding to itself based on the cell information, including: determining at least one associated cell based on its identifier; determining the distance between the associated cell and the target terminal based on its location information; obtaining the operating status of the associated cell; and determining that the associated cell is in a disabled state if the target terminal has not received a system message from the associated cell within a historical timeframe. The target terminal then determines the associated cell with the smallest distance and a disabled operating status as the energy-saving cell corresponding to the target terminal.

[0015] In this possible implementation, the target terminal determines the corresponding target terminal based on the preset associated cell information. It can prioritize the associated cell that meets the target terminal's service requirements or that the target terminal prioritizes accessing as the energy-saving cell corresponding to the target terminal, thereby enabling the target terminal to access the energy-saving cell that meets its service requirements and improving the service performance of the target terminal.

[0016] One possible implementation involves using the target terminal's historical access information for the cell. This historical access information includes one or more of the following: the identifier of the access cell successfully accessed by the target terminal, and the location information of the base station where the access cell is located. Based on the cell information, the target terminal determines the energy-saving cell corresponding to it, including: determining the distance between the access cell and the target terminal based on the location information. The target terminal obtains the operating status of the access cell. If the target terminal has not received any system messages from the access cell within the historical time period, it determines that the access cell's operating status is off. The target terminal determines the access cell with the smallest distance and operating status as off as the energy-saving cell corresponding to the target terminal.

[0017] In this possible implementation, the target terminal determines the corresponding energy-saving cell based on the cell information. It can prioritize the determination of the associated cell that meets the target terminal's service requirements or that the target terminal prefers to access as the energy-saving cell corresponding to the target terminal, thereby enabling the target terminal to access the energy-saving cell that meets its service requirements and improving the service performance of the target terminal.

[0018] One possible implementation is that the cell information is a migration instruction message sent by the current serving cell of the target terminal. The migration instruction message includes: an energy-saving cell identifier corresponding to the target terminal. The energy-saving cell can be the co-coverage cell with the lowest service load when the service load of the serving cell exceeds a load threshold, and which is in a powered-off state. Alternatively, the energy-saving cell can be the co-coverage cell with a service load that is powered-off when the service load of the serving cell does not exceed a load threshold, and whose historical average service rate is not less than the target terminal's expected rate or whose historical average service latency is not greater than the target terminal's expected latency. The target terminal determines the energy-saving cell corresponding to itself based on the cell information, including: the target terminal determining the energy-saving cell corresponding to itself based on the energy-saving cell identifier.

[0019] In this possible implementation, the target terminal can determine the corresponding energy-saving cell based on the migration instruction message. The cell with the lowest service load over a historical period, or whose average service rate and average service latency meet the target terminal's service performance requirements, can be identified as the energy-saving cell corresponding to the target terminal. This allows the target terminal to connect to the energy-saving cell that meets its service requirements, thereby improving the target terminal's service performance.

[0020] One possible implementation is that the target power is the sum of the preset power of the target terminal and the path loss power of the target terminal sending signals to the energy-saving cell.

[0021] In this possible implementation, the target terminal determines the path loss power based on the distance between the target terminal and the energy-saving cell, and determines the target power based on the target terminal's preset power and path loss power. Then, it sends a probe signal to the energy-saving cell according to the target power, which can eliminate the path loss in the probe signal transmission path, so that the power received by the energy-saving cell is the same as the target power required by the target terminal, making it easier for the energy-saving cell to determine its actual service requirements.

[0022] Thirdly, this application provides a wake-up device for an energy-saving community, which is applied to an energy-saving community and includes: a receiving module, a determining module, and a working state switching module.

[0023] The receiving module is used to receive probe signals sent by the target terminal. The target terminal includes one or more of the following: a terminal that has received an access failure indication message, and a terminal that has received a migration indication message sent by its current serving cell. The access failure indication message and the migration indication message are used to instruct the target terminal to identify an energy-saving cell and send the probe signals to that cell.

[0024] The determination module is used to determine the wake-up time of the energy-saving community based on the detection signal.

[0025] The working state switching module is used to enter the working state and connect to the target terminal at the wake-up time.

[0026] One possible implementation involves the detection signal including: detection signal power and detection period of the detection signal.

[0027] The determination module is specifically used to determine the target time period if the energy-saving community detects that the power of the detection signal during the detection time period is greater than a power threshold within the monitoring cycle. The monitoring cycle includes multiple detection time periods. If the number of target time periods detected by the energy-saving community within the monitoring cycle is greater than a number threshold, the end time of the monitoring cycle is determined as the wake-up time of the energy-saving community.

[0028] Fourthly, this application provides a wake-up device for an energy-saving cell, applied to a target terminal, comprising: a determination module and a transmission module.

[0029] The determination module is used to identify the energy-saving cell corresponding to the target terminal based on the cell information. The cell information includes one or more of the following: preset associated cell information, historical access information of the target terminal, and migration instruction messages sent by the current serving cell of the target terminal.

[0030] The transmitting module is used to send detection signals to the energy-saving community according to the target power.

[0031] One possible implementation is that the cell information is preset associated cell information. The associated cell information includes one or more of the following: the identifier of the associated cell, and the location information of the base station where the associated cell is located.

[0032] The determination module is specifically used to identify at least one associated cell based on the identifier of the associated cell. Based on location information, it determines the distance between the associated cell and the target terminal.

[0033] The wake-up device for energy-saving communities provided in this application also includes: an acquisition module for acquiring the working status of associated communities.

[0034] The determination module is also used to determine that if the target terminal has not received a system message from the associated cell within a historical time period, the working state of the associated cell is determined to be in the off state. The associated cell with the smallest distance that is in the off state is determined to be the energy-saving cell corresponding to the target terminal.

[0035] One possible implementation is that the cell information is the target terminal's historical access information. The historical access information includes one or more of the following: the identifier of the access cell that the target terminal successfully accessed, and the location information of the base station where the access cell is located.

[0036] The determination module is specifically used to determine the distance between the access cell and the target terminal based on location information.

[0037] The wake-up device for the energy-saving community provided in this application also includes: an acquisition module for acquiring the working status of the accessed community.

[0038] The determination module is also used to determine the working state of the access cell as off if the target terminal has not received a system message from the access cell within a historical time period. The access cell with the smallest distance that is in the off state is determined to be the energy-saving cell corresponding to the target terminal.

[0039] One possible implementation is that the cell information is a migration instruction message sent by the current serving cell of the target terminal. The migration instruction message includes: the energy-saving cell identifier corresponding to the target terminal. The energy-saving cell can be the co-coverage cell with the lowest service load when the service load of the serving cell exceeds a load threshold, and which is in a powered-off state. Alternatively, the energy-saving cell can be a co-coverage cell with a service load that is powered-off when the service load of the serving cell does not exceed a load threshold, and whose historical average service rate is not less than the target terminal's expected rate or whose historical average service latency is not greater than the target terminal's expected latency.

[0040] The determination module is specifically used to determine the energy-saving community corresponding to the target terminal based on the energy-saving community identifier.

[0041] One possible implementation is that the target power is the sum of the preset power of the target terminal and the path loss power of the target terminal sending signals to the energy-saving cell.

This function can be implemented by hardware or by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above-described function.

[0056] Furthermore, the network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0057] To facilitate understanding, the relevant technical terms involved in this application will be explained first.

[0058] The detection signal is a different detection signal for each cell in the preset area; each detection signal corresponds to a detection time period, a detection frequency band, and a transmission period; different detection signals occupy different time and frequency resources; the detection signal includes, but is not limited to, the detection time period, detection frequency band, and transmission period information corresponding to the detection signal; the detection signal information includes the detection time period, detection frequency band, and transmission period corresponding to the detection signal, which can be preset in the base station where each cell is located in the preset area.

[0059] Different detection signals are orthogonal in the time or frequency domain, meaning they occupy non-overlapping time or frequency resources. The detection period includes several symbols in a system frame, which can be represented by symbols. The detection frequency band includes several subcarriers in the cell's operating frequency band, which can be represented by subcarrier identifiers. For example, for detection signal 1, the corresponding detection period is {symbol3, symbol6, symbol9} and the detection frequency band is {subcarrier3, subcarrier6, subcarrier9}. For detection signal 2, the corresponding detection period is {symbol4, symbol6, symbol10} and the detection frequency band is {subcarrier4, subcarrier7, subcarrier10}.

[0060] The transmission periods of different detection signals can be the same or different; the transmission period of a detection signal can be expressed as the duration of several system frames; for example, the transmission period of detection signal 1 is the duration of 10 system frames, and the transmission period of detection signal 2 is the duration of 20 system frames.

[0061] The detection signal information corresponding to each cell is sent to the terminal through a first message; wherein, the first message is sent to the terminal by the cell, and the sending method can be a cell system broadcast message or an RRC message; the first message carries the detection signal corresponding to the cell.

[0062] It should be noted that when the cell is in working condition, it can send the first message to the terminal; when the cell is in shutdown condition, it will no longer send the first message; the energy-saving cell and the target terminal receive or transmit detection signals according to the transmission cycle of the detection signal, during the detection period and on the detection frequency band.

[0063] An energy-saving cell is a cell that is in a shutdown state. Energy-saving cells can determine when to enter a shutdown state based on service load to achieve base station energy saving. For example, an energy-saving cell enters a shutdown state when the service load statistics within a preset historical period are less than a shutdown threshold, or when the predicted service load within a future period is less than the shutdown threshold.

[0064] The associated cell is the cell that meets the terminal's service needs or is given priority access. For example, if the terminal is a private network terminal, then the associated cell is a private network cell.

[0065] The monitoring period, which is the period for determining the wake-up time, can include multiple consecutive detection periods.

[0066] Currently, in cell shutdown technology, after an energy-saving cell enters the shutdown state, neighboring cells within the same area determine the wake-up time of the energy-saving cell based on their own service load. That is, when the service load of a neighboring cell exceeds a preset threshold, the energy-saving cell in the shutdown state is woken up, enabling it to enter the working state, thus achieving wake-up based on the service load of the neighboring cells. However, in this technology, because the signal coverage areas of neighboring cells and energy-saving cells cannot completely overlap in actual networks, the service load of neighboring cells cannot accurately reflect the service demand under the energy-saving cell.

[0067] In timed wake-up technology, energy-saving communities can enter the working state at a specified time according to a preset wake-up time, achieving wake-up based on timed information. However, in timed wake-up technology, the wake-up time is statically configured and cannot dynamically adapt to changes in the service needs of the energy-saving community.

[0068] Therefore, existing energy-saving cell wake-up methods result in inaccurate wake-up times, failing to match the actual service needs of the energy-saving cell. This could lead to the energy-saving cell being woken up when actual service demand is low, wasting resources and affecting energy-saving performance; or it could fail to wake up the energy-saving cell in a timely manner when actual service demand is high, failing to meet the access needs of the user equipment (UE) and impacting UE service performance.

[0069] Based on this, this application provides a wake-up method for an energy-saving cell. The basic principle is as follows: after receiving a detection signal sent by a target terminal, the energy-saving cell determines the wake-up time of the energy-saving cell according to the detection signal, and then enters the working state at the wake-up time and connects to the target terminal.

[0070] This application determines the wake-up time of the energy-saving cell based on the detection signal sent by the target terminal after receiving the detection signal containing the actual service of the target terminal, and enters the working state at the wake-up time. By combining the actual service needs of the target terminal, the wake-up time of the energy-saving cell can be accurately determined, so that the wake-up time of the energy-saving cell matches the actual service needs of the energy-saving cell, realizing on-demand wake-up of the energy-saving cell, and taking into account both energy saving effect and service performance.

[0071] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0072] The solution provided in this application can be applied to... Figure 1 The illustrated wake-up system 100 for an energy-saving community includes: an energy-saving community 101 and a target terminal 102.

[0073] Among them, the energy-saving cell 101 is used to receive the detection signal sent by the first terminal 102, and then determine the wake-up time of the energy-saving cell 101 based on the detection signal, and finally enter the working state at the wake-up time and access the first terminal 102.

[0074] The target terminal 102 is used to determine the energy-saving cell 101 corresponding to the target terminal 102 based on the cell information, and then send a detection signal to the energy-saving cell 101 according to the target power.

[0075] The cell message includes one or more of the following: preset associated cell information, historical access information of the target terminal, and migration instruction message sent by the current serving cell of the target terminal.

[0076] Specifically, such as Figure 2 As shown, the target terminal 102 may include: a first terminal 103 and a second terminal 104. The wake-up system 100 of the energy-saving cell may further include: a serving cell 105. The serving cell 105 is the cell currently served by the second terminal 104, and the serving cell 105 is in an active state.

[0077] The first terminal 103 is the terminal that receives a cell access failure indication message when it needs to access a cell. The cell access failure indication message may include one or more of the following: RRC connection rejection, RRC establishment failure, bearer establishment failure, radio link failure, etc. After receiving the cell access failure indication message, the first terminal 102 determines the energy-saving cell 101 corresponding to the first terminal 103 based on preset associated cell information or the first terminal's historical access information, and then sends a probe signal to the corresponding energy-saving cell 101 according to the target power.

[0078] The second terminal 104 is the terminal that receives the migration instruction message sent by the serving cell 105. This migration instruction message instructs the second terminal 104 to migrate from the serving cell 105 to the energy-saving cell 101. After receiving the migration instruction message from the serving cell 105, the second terminal 104 determines the energy-saving cell 101 corresponding to itself based on the message, and then sends a detection signal to the energy-saving cell 101 according to the target power. The migration instruction message carries the identifier of the second terminal 104, the identifier of the energy-saving cell 101 corresponding to the second terminal 104, and migration instruction information.

[0079] It should be noted that the target terminal may include one or more first terminals and / or one or more second terminals; one monitoring period corresponds to a set of target terminals, and the corresponding target terminals may be different in different monitoring periods. The target terminals corresponding to each monitoring period can be updated according to the cell access status or migration indication message sending status of each terminal in the preset area; the target terminals in the preset area can send probe signals, while other terminals outside the target terminals in the preset area cannot send probe signals.

[0080] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0081] On the one hand, this application provides a wake-up method for an energy-saving cell, which can be applied to the wake-up system 100 of the aforementioned energy-saving cell. The solution of this application will be described in detail below through the interaction process between the energy-saving cell and the target terminal.

[0082] like Figure 3 As shown, the wake-up method for energy-saving communities disclosed in this application may include the following steps:

[0083] S301, the target terminal determines the energy-saving cell corresponding to the target terminal based on the cell information.

[0084] The cell information includes: preset associated cell information, historical access information of the target terminal, and migration instruction messages sent by the current serving cell of the target terminal.

[0085] One possible implementation is that the cell information is preset associated cell information. The associated cell information includes one or more of the following: the identifier of the associated cell, and the location information of the base station where the associated cell is located.

[0086] The target terminal determines the energy-saving cell corresponding to it based on cell information, including: identifying at least one associated cell based on the identifier of the associated cell; determining the distance between the target terminal and the associated cell based on location information; obtaining the operating status of the associated cell; and determining the associated cell with the smallest distance that is in the off state as the energy-saving cell corresponding to the target terminal.

[0087] It should be noted that the target terminal can obtain the working status of the associated cell by determining whether the cell is in a shutdown state by judging whether the target terminal has received a system message from a certain cell within a preset time period before the current time; if no system message is received from a certain cell within the preset time period before the current time, the cell is considered to be in a shutdown state; wherein, the preset time period is longer than the maximum period for system message transmission of each cell.

[0088] For example, the target terminal contains pre-set cell information, which includes the identifier of the associated cell, the corresponding detection signal, and the location information of the base station where the associated cell is located.

[0089] The target terminal determines its associated cell based on the identifier of the associated cell in the preset cell information. At the beginning of each monitoring cycle, it determines its current location using GPS or other positioning technologies. Then, based on the location information of the base station where the associated cell is located and the target terminal's current location, it determines the distance between the target terminal and the associated cell. Next, the target terminal obtains the working status of the associated cell. Finally, the associated cell with the smallest distance to the target terminal (less than a preset distance threshold) that is in a powered-off state is identified as the energy-saving cell corresponding to the target terminal.

[0090] Another possible implementation is that the cell information is the target terminal's historical access information. The historical access information includes one or more of the following: the identifier of the access cell that the target terminal successfully accessed, and the location information of the base station where the access cell is located.

[0091] The target terminal determines the energy-saving cell corresponding to the target terminal based on the cell information, including:

[0092] The target terminal determines the distance between itself and the access cell based on location information. The target terminal obtains the operating status of the access cell. The target terminal determines that the access cell with the shortest operating status (off) is the energy-saving cell corresponding to the target terminal.

[0093] It should be noted that the process by which the target terminal obtains the working status of the candidate cell can refer to the process by which the target terminal obtains the working status of the associated cell, and will not be elaborated here.

[0094] For example, the target terminal stores the identifiers of the access cells that were successfully accessed within a preset time period before the current time, the corresponding detection information, and the location information of the base station where the access cell is located.

[0095] The target terminal determines the access cell based on the identifier of the access cell in the historical access information. At the beginning of each monitoring period, the target terminal identifies the access cell that is in the off state among the cells that were successfully accessed within a preset time period before the current time as candidate cells.

[0096] The target terminal determines its location in front of the building at any given time based on GPS and other positioning technologies. Then, based on the location information of the base stations where candidate cells are located and the target terminal's location information, the distance between the target terminal and each candidate cell is determined. Next, the target terminal obtains the operating status of the candidate cells. Finally, among the candidate cells whose distance to the target terminal is less than a preset distance threshold, the candidate cell with the smallest distance to the target terminal is determined as the energy-saving cell corresponding to the target terminal.

[0097] Another possible implementation is that the cell information is a migration instruction message sent by the current serving cell of the target terminal. The migration instruction message includes: the energy-saving cell identifier corresponding to the target terminal. The energy-saving cell can be the co-coverage cell whose operating state is off and whose operating load is the lowest when the service load of the serving cell exceeds the load threshold. Alternatively, the energy-saving cell can also be a co-coverage cell whose operating state is off when the service load of the serving cell does not exceed the load threshold, and whose historical average service rate is not less than the target terminal's expected rate or whose historical average service latency is not greater than the target terminal's expected latency.

[0098] The target terminal determines the energy-saving cell corresponding to the target terminal based on the cell information, including: the target terminal determines the energy-saving cell corresponding to the target terminal based on the identifier of the energy-saving cell.

[0099] For example, when the serving cell meets preset conditions, it sends a migration instruction message to the target terminal. This migration instruction message carries the terminal's identifier, the identifier of the energy-saving cell corresponding to the terminal, the corresponding detection signal, and migration instruction information. During the monitoring period, if the target terminal receives the migration instruction message from the serving cell, it determines the energy-saving cell corresponding to the target terminal based on the energy-saving cell's identifier.

[0100] The process of sending a migration instruction message to the target terminal when the serving cell meets the preset conditions is as follows:

[0101] The service area obtains historical information for each covered area according to the monitoring cycle.

[0102] It should be noted that the process by which the serving cell obtains historical information from each co-coverage cell can be as follows: the serving cell sends a historical information request message to each co-coverage cell according to a monitoring cycle. This message carries the serving cell identifier and cell information request indication information. In response, each co-coverage cell, upon receiving the historical information request message from the serving cell, sends a cell information indication message to the serving cell. This cell information indication message carries the co-coverage cell identifier and the cell's historical information.

[0103] The process by which the serving cell obtains historical information from each co-coverage cell can also involve each co-coverage cell sending a cell information indication message to the serving cell according to a monitoring cycle. This historical information includes the cell's average service load, average service rate, and average service latency over a historical period. Co-coverage cells and the serving cell share the same wireless signal coverage area, and the co-coverage cell identifier for each cell can be preset in the base station.

[0104] The service cell determines the target terminal and the corresponding energy-saving cell based on the historical information of the cells under the same coverage.

[0105] Specifically, if all cells within the serving cell's coverage area are offline, and the serving cell's service load exceeds a preset load threshold, then the edge terminal within the serving cell is identified as the target terminal. Specifically, the edge terminal receives a serving cell signal strength below a signal strength threshold. The serving cell identifies the edge terminal based on a measurement report sent by the terminal, which includes the serving cell signal strength measured by the terminal. The serving cell then designates any one of the cells within its coverage area, or the one with the lowest service load, as the energy-saving cell corresponding to the target terminal.

[0106] If all cells in the same coverage area of ​​the serving cell are in a powered-off state, and the service load of the serving cell is not greater than the load threshold, and the service rate of any terminal under the serving cell is less than the terminal's expected rate or the service latency of the terminal is greater than the terminal's expected latency, then the terminal is identified as the target terminal. The terminal's expected rate and expected latency can be obtained from the service request message sent by the terminal, or from the core network equipment connected to the serving cell.

[0107] If the average service rate of the same coverage cell over a historical period is not less than the expected rate of the target terminal, or the average service latency of the same coverage cell over a historical period is not greater than the expected latency of the target terminal, then the same coverage cell is identified as the energy-saving cell corresponding to the terminal.

[0108] It should be noted that the serving cell can determine whether a co-coverage cell is currently in a shutdown state based on the deactivation indication message and activation indication message sent by the co-coverage cell. Specifically, if a deactivation indication message from a co-coverage cell is received in the first instant before the current instant, and no activation indication message is received from a co-coverage cell after the first instant, then the co-coverage cell is considered to be in a shutdown state. The deactivation indication message and activation indication message are used to indicate whether the cell is in a shutdown state and transitioning from a shutdown state to a working state, respectively.

[0109] S302, the target terminal sends a detection signal to the energy-saving community according to the target power.

[0110] The target power is the sum of the preset power of the target terminal and the path loss power of the target terminal sending signals to the energy-saving community.

[0111] Specifically, within each monitoring cycle, the target terminal transmits a detection signal according to the target transmission cycle, during the target detection period and on the target detection frequency band, and the transmission power of the detection signal is the target power.

[0112] The target transmission cycle, target detection period, and target detection frequency band are determined based on the detection signal information of the energy-saving cell corresponding to each monitoring cycle.

[0113] The target power value can be determined based on the distance between the target terminal and the corresponding energy-saving community. The greater the distance, the greater the target power value.

[0114] One possible implementation is that the target power corresponding to the target terminal = preset power + path loss power.

[0115] The path loss power can be determined based on the distance between the target terminal and the corresponding energy-saving cell, as well as the path loss formula. The path loss formula reflects the relationship between the distance between the transceiver and the path loss value, and existing path loss formulas can be used. For 4G and 5G systems, propagation models defined in 3GPP 36.873 and 3GPP 38.901 can be used, respectively. These include various scenarios such as urban microcells (UMi), urban macrocells (UMa), rural macrocells (RMa), and indoor hotspots (InH). Each scenario is further divided into line-of-sight (LOS) and non-line-of-sight (NLOS) cases, for which corresponding path loss formulas are defined.

[0116] For example, using the UMa model corresponding to line-of-sight (LOS) communication, the path loss formula is as follows:

[0117] Path loss=28.0+22*log10(d)+20log10(fc)

[0118] Where path loss represents path loss power, d represents the distance between the target terminal and the energy-saving cell, and fc represents the target detection frequency of the target terminal.

[0119] The above formula can be used to calculate the path loss power based on the distance between the target UE and the corresponding energy-saving cell and the carrier center frequency of the energy-saving cell.

[0120] The preset power value is related to the receiving sensitivity of the base station where the energy-saving cell is located, and is the minimum power value to meet the signal detection requirements of the base station.

[0121] S303, the energy-saving community receives the detection signal sent by the target terminal.

[0122] The target terminal includes one or more of the following: a terminal that receives an access failure indication message sent by the cell, and a terminal that receives a migration indication message sent by the terminal's current serving cell. For example, the energy-saving cell, based on the detection signal information corresponding to the energy-saving cell, opens the uplink channel during each detection period according to the detection signal transmission cycle, and receives the detection signals sent by the terminal on the detection frequency band.

[0123] It should be noted that energy-saving cells can shut down the uplink channel during symbol time outside the detection period to reduce base station power consumption.

[0124] S304, the energy-saving community determines the wake-up time based on the detection signal.

[0125] Specifically, if the energy-saving community detects that the power of the detection signal exceeds a power threshold during the detection period within the monitoring cycle, the detection period is determined as the target period. This monitoring cycle can be a preset cycle.

[0126] If the number of target time periods monitored in the energy-saving community during the monitoring period exceeds the number threshold, the end time of the monitoring period is determined as the wake-up time of the energy-saving community.

[0127] For example, if the power of the detection signal received by the energy-saving community during a certain detection period is greater than a preset power threshold, then that detection period is determined as the target period. If the number of target periods within a certain monitoring cycle is greater than a preset value, then the end time of that monitoring cycle is determined as the wake-up time.

[0128] S305, the energy-saving community enters working state at the wake-up time and connects to the target terminal.

[0129] For example, an energy-saving cell enters the working state from the off state upon wake-up. At this wake-up time, the base station where the energy-saving cell is located activates its uplink and downlink channels to transmit and receive signals normally, enabling access to the target terminal.

[0130] Furthermore, if the target terminal successfully accesses the energy-saving community, the terminal will no longer belong to the target terminal, and the energy-saving community can remove the terminal from the target terminal list. At the same time, the terminal will stop sending detection signals to the energy-saving community.

[0131] If a target terminal fails to connect to the corresponding energy-saving cell, the terminal is identified as the terminal that received the access failure indication message among the target terminals, and the steps S301-S304 provided in the embodiment of this application are executed in the next monitoring cycle to re-determine the corresponding new energy-saving cell and send a detection signal to the new energy-saving cell. After the new energy-saving cell enters the working state, the target terminal is connected to the new energy-saving cell.

[0132] The wake-up method for energy-saving cells provided in this application involves a target terminal determining the corresponding energy-saving cell based on cell information, and then sending a probe signal to the energy-saving cell according to the target power. Upon receiving the probe signal from the target terminal, the energy-saving cell determines its wake-up time based on the signal, and then enters the working state at that wake-up time and connects to the target terminal. This application, by utilizing the target terminal's probe signal to match the wake-up time of the energy-saving cell with its actual service requirements, improves the accuracy of the wake-up time, enables on-demand wake-up of the energy-saving cell, and balances energy-saving effects with service performance.
