Description

Technical Field

[0001] This application relates to the field of wireless communication technology, specifically to a method, apparatus, network device, and storage medium for determining energy-saving strategies. Background Technology

[0002] Currently, the B1 event threshold (used to control the redirection of a terminal from a 4G network to a 5G network) and the B2 event threshold (used to control the handover of a terminal from a 5G network to a 4G network based on coverage) in 4G / 5G network interoperation adopt a static configuration control mechanism. That is, network operation and maintenance personnel set fixed threshold values ​​for cells based on experience or preliminary network planning.

[0003] When power-saving features (such as the partial shutdown of 5G cells) take effect, the network coverage pattern changes significantly, altering the overlap between the coverage areas of remaining 5G cells and neighboring 4G cells. Static interoperability thresholds cannot adapt to these real-time changes, causing user equipment at the coverage edge to experience a "ping-pong effect" between 4G and 5G networks, frequently performing unnecessary reselections and handovers. This not only increases network signaling overhead, offsetting the benefits of power saving, but also reduces the continuity of data services for users. Summary of the Invention

[0022] Optionally, based on the difference in signal quality between the two cells in the target cell pair, an energy-saving strategy for the corresponding base station of the target cell pair is determined, including:

[0023] Based on the difference, the energy-saving strategy, including the system switching interoperability threshold, is determined;

[0024] Wherein, when the difference is greater than or equal to zero, the system handover interoperability threshold includes: the first sum of the serving cell below the threshold and the hysteresis is less than or equal to the inter-system neighbor cell above the threshold, the serving cell below the threshold is less than or equal to the first threshold, and the inter-system neighbor cell above the threshold is greater than or equal to the second threshold and less than or equal to the third threshold.

[0053] To enable those skilled in the art to better understand the embodiments of this application, the following description is provided first:

[0054] The B1 and B2 event threshold control mechanisms in 4G / 5G network interoperability. The B1 event controls the redirection of a terminal from the 4G network to the 5G network, while the B2 event controls the handover of a terminal from the 5G network to the 4G network based on coverage. Existing networks typically use static configuration to set these threshold values. For example, network operators set fixed Reference Signal Received Power (RSRP) threshold values ​​for cells based on experience or preliminary network planning. These parameters generally do not automatically adjust with real-time network status changes after configuration.

[0055] Specifically, the system interoperability threshold values ​​include: B1 event threshold (inter-system neighbor cell above threshold B1ThresholdRsrp), and B2 event threshold (serving cell below threshold RsrpCandidateB21 and inter-system neighbor cell above threshold RsrpCandidateB22).

[0056] As described in the background section, in the prior art, terminals may encounter unexpected situations such as cell access failure, slice access failure, or slice QoS rollback after cell reselection or access, which seriously affects the user experience. In order to solve at least one of the above problems, this application provides an energy-saving strategy determination method, which can reduce or avoid the occurrence of the above situations, improve communication efficiency, and improve the user experience.

[0057] This application provides a method and apparatus for determining an energy-saving strategy. The method and apparatus are based on the same concept, and since they solve problems based on similar principles, their implementations can be mutually referenced; repeated details will not be repeated.

[0058] like Figure 2 As shown in the embodiment of this application, an energy-saving strategy determination method includes the following steps:

[0059] Step 201: After determining that the energy-saving mode of the base station is effective, obtain the measurement reports of the first cell and the second cell; the first cell is the cell corresponding to the first coverage direction of the base station, and the second cell is the neighboring cell of the first cell;

[0060] Step 202: Based on the measurement report, cluster the first cell and the second cell to obtain at least one cell pair; the cell pair includes two cells that belong to different standards, have overlapping wireless signal coverage, and the terminal's handover frequency between them is greater than a preset frequency;

[0061] Step 203: Calculate the priority score corresponding to each cell pair based on the overlap information between the two cells in each cell pair;

[0062] Step 204: Determine the target cell pair in the at least one cell pair whose priority score is greater than a first preset threshold;

[0063] Step 205: Determine the energy-saving strategy for the base station corresponding to the target cell pair based on the difference in signal quality between the two cells in the target cell pair.

[0064] The energy-saving strategy determination method in this embodiment of the application performs clustering processing on a first cell and its adjacent second cell based on the cell measurement report to obtain cell pairs belonging to different standards, having overlapping wireless signal coverage, and where the terminal's handover frequency between them is greater than a preset frequency; and determines the priority score of each cell pair based on the overlap information between the two cells in each cell pair; finally, it determines the energy-saving strategy of the base station corresponding to the target cell pair based on the difference in signal quality between the two cells in the target cell pair determined according to the priority score. In the scheme of this embodiment of the application, the determination of the energy-saving strategy changes according to the changes in real-time network coverage and signal coverage overlap between cells, which can suppress unnecessary frequent handovers between networks by the terminal, maintaining excellent user service experience while ensuring energy saving effect.

[0065] Optionally, the first coverage direction is north;

[0066] The measurement report is a measurement report within a preset time period; for example, the measurement report is a measurement report between a certain minute and a certain minute on a certain day of a certain month of a certain year.

[0067] It should be noted that the energy-saving status of the base station is determined by monitoring event notifications from the network management system or by actively querying the base station's operating status.

[0068] In this embodiment of the application, for 5G cells, the activation status of their power-saving modes is acquired in real time, such as channel shutdown, carrier shutdown, deep sleep, etc.; the energy-saving data collection for the corresponding network-managed cells is shown in Table 1:

[0069] Table 1

[0070]

[0071] It should be noted that, in the embodiments of this application, the phrase "after determining that the energy-saving mode of the base station is effective" can be understood as: after confirming that the energy-saving mode of the base station is effective for a preset period of time.

[0072] In this embodiment of the application, the preset duration is 15 minutes; by introducing the preset duration of the waiting period, it can be ensured that the coverage change tends to be stable.

[0073] Optionally, the measurement report includes at least one of the following: timestamp, serving cell signal quality, neighboring cell signal quality, serving cell location information, and serving cell identifier.

[0074] Optionally, the measurement reports are shown in Tables 2 and 3:

[0075] Table 2 Measurement Report of Service Area

[0076]

[0077] Table 3 Measurement Reports of Neighboring Systems

[0078]

[0079] Optionally, the first cell and the second cell are clustered based on the measurement report to obtain at least one cell pair, including:

[0080] Based on the measurement report, a clustering algorithm is used to perform clustering analysis on the location information and signal quality of the first cell and the second cell, resulting in multiple cell clusters with overlapping signals and a distance less than a preset distance.

[0081] Identify at least one cell pair in each cell cluster where the handover frequency between terminals is greater than a preset frequency.

[0082] Optionally, based on the measurement report, a clustering algorithm is used to perform cluster analysis on the location information and signal quality of the first cell and the second cell, including:

[0083] Based on the measurement report and cell parameters, an improved K-Means clustering algorithm is used to perform clustering analysis on the location information and signal quality of the first cell and the second cell to obtain the cell cluster.

[0084] Optionally, the engineering parameters of the community include latitude and longitude, azimuth, etc.

[0085] Cluster analysis of the location information and signal quality of the first cell and the second cell can be understood as follows:

[0086] Cluster analysis was performed on the location information of the first cell and the second cell;

[0087] Furthermore, cluster analysis is performed on the signal quality of the first cell and the second cell.

[0088] In this embodiment of the application, the K-Means clustering algorithm is used to cluster the user's real-time measurement reports (MR), and areas with similar geographical locations and overlapping 4G / 5G signal coverage are divided into a cluster.

[0089] Each cluster (i.e. a signal overlap coverage area) is distinguished by a number k (e.g., k=1,2,3,..., representing different signal overlap coverage areas respectively).

[0090] The energy-saving strategy determination method in this application not only considers static operating parameters but also focuses on analyzing the actual wireless signal coverage overlap in each campus after power saving. It performs cluster analysis on the cells, resulting in cell pairs with high real-time efficiency. Through clustering algorithms, it is determined that after base station energy saving, there is significant overlap in the signal coverage of 4G and 5G cells, and these areas are high-incidence areas for abnormal handover behavior. This precisely narrows the target of the energy-saving strategy to the most needed objective, avoiding network-wide parameter oscillations.

[0091] Optionally, the overlap information includes: the overlap of radio signal coverage between the two cells in each cell pair, the handover frequency, and the distance between the two cells in each cell pair;

[0092] Based on the overlap information between the two cells in each cell pair, a priority score is calculated for each cell pair, including:

[0093] The degree of overlap of the wireless signal coverage of the cell pair is determined based on the overlapping range of the wireless signal coverage of the two cells in the cell pair.

[0094] Based on the handover frequency, determine the handover frequency deviation of the cell pair from the historical average handover frequency;

[0095] The distance factor of the cell pair is determined based on the distance between the two cells in the cell pair.

[0096] The priority score of the cell pair is obtained by weighted summation of the wireless signal coverage overlap, the handover frequency deviation, and the distance factor.

[0097] In this embodiment of the application, the wireless signal coverage overlap of the cell pair is determined using the following formula based on the overlapping range of the wireless signal coverage of the two cells in the cell pair:

[0098] ;

[0099] in, This represents the overlap coverage between 4G and 5G cells (two cells in the cell pair), with a value of (0, 1); N represents the cell sampling data of 5G and 4G cells in the measurement report (including timestamp, serving cell signal quality, neighboring cell signal quality, serving cell location information, serving cell identifier, and signal level), expressed as... This represents the total number of samples with effective 4G cell coverage. This represents the total number of samples with effective 5G cell coverage. and Indicates in cluster The number of effective coverage samples within the (signal overlap coverage area) (RSRP≥−110dBm).

[0100] Optionally, the handover frequency deviation of the cell pair from the historical average handover frequency can be determined using the following formula:

[0101] ;

[0102] in, This is the current switching frequency; The average switching frequency for its historical period (e.g., the same time period on every Wednesday of the past four weeks);

[0103] The threshold for the handover deviation rate can be set to 50%. That is, when the handover deviation rate is greater than 50%, it is considered that the cell has experienced an abnormal handover behavior that requires attention under the current power saving scenario.

[0104] In this embodiment of the application, the switching frequency is determined by the following formula:

[0105] ;

[0106] in, This refers to the frequency at which the terminal switches between 4G and 5G cells within the current statistical period (e.g., ΔT = 15 minutes). This represents the total number of times a terminal switches between 4G and 5G cells within the current statistical period.

[0107] Optionally, the priority score of the cell pair is obtained by weighted summation of the wireless signal coverage overlap, the handover frequency deviation, and the distance factor, including:

[0108] ;

[0109] in, Score based on priority;

[0110] Overlap coverage;

[0111] The distance between small intervals, This is set as a maximum effective influence distance (e.g., 2km), ensuring that the closer the distance, the higher the score;

[0112] , , These are weighting coefficients, all of which are set through training on historical data or expert experience to meet certain requirements. .

[0113] Optionally, the first preset threshold is dynamically determined based on the statistical distribution of the priority scores of all cell pairs.

[0114] The energy-saving strategy determination method of this application embodiment determines the calculation model of the priority score by comprehensively considering signal coverage overlap, handover deviation rate and geographical proximity. By calculating the priority score of the cell, it can more accurately determine the cell that needs to implement the energy-saving strategy, thereby maximizing the effect of the energy-saving strategy.

[0115] Optionally, based on the difference in signal quality between the two cells in the target cell pair, an energy-saving strategy for the corresponding base station of the target cell pair is determined, including:

[0116] Based on the difference, the energy-saving strategy, including the system switching interoperability threshold, is determined;

[0117] Wherein, when the difference is greater than or equal to zero, the system handover interoperability threshold includes: the first sum of the serving cell below the threshold and the hysteresis is less than or equal to the inter-system neighbor cell above the threshold, the serving cell below the threshold is less than or equal to the first threshold, and the inter-system neighbor cell above the threshold is greater than or equal to the second threshold and less than or equal to the third threshold.

[0118] When the difference is less than zero, the system handover interoperability threshold includes: the inter-system neighbor cell higher threshold is greater than or equal to the fourth threshold and less than or equal to the fifth threshold, the serving cell lower threshold is greater than or equal to the first threshold, the first sum is less than or equal to the inter-system neighbor cell higher threshold, and the inter-system neighbor cell higher threshold is greater than or equal to the second threshold and less than or equal to the third threshold.

[0119] Wherein, the first threshold is the minimum value of the serving cell below the threshold, the second threshold is the minimum value of the inter-system neighboring cell above the threshold, the third threshold is the maximum value of the inter-system neighboring cell above the threshold, the fourth threshold is the minimum value of the inter-system neighboring cell above the threshold, and the fifth threshold is the maximum value of the inter-system neighboring cell above the threshold.

[0120] The signal quality is determined based on at least one of the following: reference signal received power, reference signal received quality (RSRQ), and signal-to-interference-plus-noise ratio (SINR).

[0121] In this embodiment of the application, in order to avoid the limitation of fixed adjustment boundaries, an adaptive boundary adjustment mechanism is introduced, so that the parameter generation rules themselves have learning capabilities;

[0122] Specifically: First, for each target cell pair, the real-time strength difference (ΔRSRP or ΔRSRQ) between its 5G cell signal quality (NR RSRP or NRRSRQ) and its 4G cell signal quality (LTE RSRP or LTE RSRQ) is calculated.

[0123] Based on the difference, a preset dynamic adjustment model is applied to calculate the B1 and B2 thresholds for each cell individually.

[0124] In this embodiment, when the difference indicates that the 5G signal is significantly stronger than the 4G signal, the B2 threshold for switching from 5G to 4G is appropriately lowered to encourage users to stay on 5G; conversely, the B2 threshold is raised to encourage users to switch to 4G earlier. The B1 threshold for switching from 4G to 5G is also dynamically adjusted using symmetrical logic.

[0125] Optionally, the difference is the average of multiple differences;

[0126] Specifically, taking ΔRSRP as an example, for the target cell pair, the difference is calculated as follows:

[0127] ;

[0128] This represents the real-time level difference between 4G and 5G cells (the difference).

[0129] ;

[0130] in, The mean of multiple differences is used. Since the ΔRSRP of a single sample may be affected by transient interference (such as user movement or obstruction) and fluctuate drastically, the mean is introduced. The difference is calculated by taking the number of M valid samples in the overlapping area to offset the influence of transient noise and more accurately reflect the long-term signal strength relationship between 5G and 4G in the overlapping area.

[0131] Optionally, the threshold adjustment no longer uses a fixed boundary value, but is calculated based on a dynamically adjustable "adaptive boundary pool"; the values ​​of the system interoperability thresholds in this embodiment are shown in Table 4:

[0132] Table 4

[0133]

[0134] It should be noted that, as Figure 3 As shown, the difference is greater than or equal to zero, meaning the 5G signal is superior to 4G. From the current adaptive boundary pool, a set of values ​​is selected for the serving cell being below the threshold RsrpcandidateB21 and the inter-system neighboring cell being above the threshold RsrpcandidateB22, aiming to encourage terminals to camp on 5G cells. The selection principle must satisfy the following: RsrpcandidateB21 should be relatively lenient to prevent ping-pong between the 4G and 5G thresholds; the following must also be satisfied:

[0135] ;

[0136] ;

[0137] To ensure a rapid switch to 4G when the 5G signal is weaker than -110dBm, the following conditions must be met:

[0138] ;

[0139] If the difference is greater than or equal to zero, it indicates that the 4G signal is generally stronger than the 5G signal. In this case, to ensure a better user experience, users should prioritize camping on 4G cells, and the 4G to 5G redirection threshold needs to be increased.

[0140]

[0141] To prevent ping-pong at the 4G / 5G thresholds and to meet the local decision threshold B21 and remote decision threshold B22 for 5G to 4G handover as quickly as possible, namely:

[0142] ;

[0143] ;

[0144] ;

[0145] in, The neighboring region of the heterogeneous system is above the threshold;

[0146] The serving cell is below the threshold; The minimum value below the threshold for the serving cell;

[0147] The neighboring region of the heterogeneous system is above the threshold; The minimum value of the neighboring region of the heterogeneous system that exceeds the threshold; This is the maximum value of the neighboring regions of the heterogeneous system that exceeds the threshold.

[0148] Optionally, the method further includes:

[0149] Two cells in a cell pair implementing the energy-saving strategy are detected to obtain a target measurement report;

[0150] Based on the target measurement report, determine the handover frequency and handover success rate between the two cells in the cell pair.

[0151] If the switching frequency is greater than a second preset threshold, or the switching success rate is less than a third preset threshold, the system switching interoperability threshold is adjusted.

[0152] In this embodiment of the application, after the energy-saving strategy is implemented in the target cell pair, the key indicators of the cells in the target cell pair are continuously detected (to obtain the target measurement report).

[0153] If the metrics show that the optimization effect meets expectations (e.g., a significant decrease in the number of frequent switching and a stable switching success rate), the system will not only continue to execute the energy-saving strategy, but will also strengthen the threshold range on which the parameter is based. If a deterioration in the metrics is detected, the threshold range will be narrowed or shifted, and this "failure" will be recorded to prevent similar undesirable parameters from being generated in subsequent optimizations. Data will also be recorded for iterative optimization of the algorithm model.

[0154] like Figure 4 As shown, the energy-saving strategy determination method of this application embodiment includes:

[0155] Whether the energy-saving mode of the base station is effective is determined by monitoring the status or key indicators of the base station nodes.

[0156] After confirming that the energy-saving mode of the base station is in effect, wait for a preset time, and then perform network measurements after the network stabilizes to obtain a measurement report MR.

[0157] Based on clustering algorithms, two cells belonging to different standards, with overlapping wireless signal coverage, and whose terminal switching frequency between them is greater than a preset frequency are selected for accurate target identification.

[0158] By combining information such as overlapping wireless signal coverage, the priority score of each cell pair is determined, as well as the difference in signal quality between the two cells in each target cell pair (e.g., ΔRSRP).

[0159] Based on the difference in signal quality between the two cells in each target cell, calculate the energy-saving strategy for the optimal dynamic threshold adjustment data;

[0160] This energy-saving strategy can be automatically executed by adjusting network management parameters;

[0161] By testing two cells in a pair of cells implementing this energy-saving strategy, it can be determined whether there is a deterioration in the perceived indicators of the two cells.

[0162] If it does not exist, the energy-saving strategy will continue to be executed; if it does exist, the dynamic threshold will be adjusted.

[0166] Clustering module 502 is used to perform clustering processing on the first cell and the second cell according to the measurement report to obtain at least one cell pair; the cell pair includes: two cells that belong to different standards, have overlapping wireless signal coverage, and the terminal switching frequency between them is greater than a preset frequency;

[0167] The calculation module 503 is used to calculate the priority score corresponding to each cell pair based on the overlap information between the two cells in each cell pair.

[0168] The first determining module 504 is used to determine the target cell pair in the at least one cell pair whose priority score is greater than a first preset threshold.

[0169] The second determining module 505 is used to determine the energy-saving strategy of the base station corresponding to the target cell pair based on the difference in signal quality between the two cells in the target cell pair.

[0170] The energy-saving strategy determination device in this embodiment performs clustering processing on a first cell and its adjacent second cell based on the cell measurement report to obtain cell pairs belonging to different standards, having overlapping wireless signal coverage, and where the terminal's handover frequency between them is greater than a preset frequency. It then determines the priority score of each cell pair based on the overlap information between the two cells in each cell pair. Finally, it determines the energy-saving strategy for the base station corresponding to the target cell pair based on the difference in signal quality between the two cells in the target cell pair determined according to the priority score. In this embodiment, the energy-saving strategy is determined according to changes in real-time network coverage and signal coverage overlap between cells, which can suppress unnecessary frequent handovers between networks by the terminal, maintaining excellent user service experience while ensuring energy saving.
