Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, apparatus, electronic device and storage medium for load balancing across different frequency bands. Background Technology

[0002] In wireless communication networks, the F-band serves as an effective supplement to the D-band signal, providing wider coverage. However, it has a lower priority. Handover and reselection of base station signals in 4G mobile communication technology are mostly due to signal attenuation, load imbalance, improper mobility management, network congestion, and equipment failure. To solve these problems, it is necessary to comprehensively consider multiple factors, such as equipment performance, network topology, and user distribution, to formulate reasonable cell handover and reselection strategies to improve communication continuity and quality.

[0003] In related technologies, the configuration thresholds for cell handover and cell reselection adopt the unified specifications of the provincial company. However, due to the randomness of user distribution areas, the unified strategy cannot be applied to complex wireless environments, resulting in uneven load on cells corresponding to the D / F bands. In addition, the daily D / F handover and reselection parameter configuration relies too much on expert experience, but the skill levels of existing optimization personnel vary, which may lead to low efficiency in cell handover and reselection and failure to quickly achieve a balanced effect. Summary of the Invention

[0004] This disclosure presents a method, apparatus, electronic device, storage medium, and computer program product for load balancing across different frequency bands, aiming to at least partially solve technical problems in the related art.

[0005] The first aspect of this disclosure provides a method for inter-frequency band load balancing, comprising: determining a first cell and a second cell associated with a terminal device, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal; determining a first signal strength of the first frequency band signal and a second signal strength of the second frequency band signal; determining a first communication load level corresponding to the first cell and a second communication load level corresponding to the second cell; determining an inter-frequency handover threshold based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal; and triggering the terminal device to perform cell handover or cell reselection based on the relationship, the inter-frequency handover threshold, the first signal strength, and the second signal strength.

[0006] A second aspect of this disclosure provides an inter-frequency band load balancing device, comprising: a first determining module for determining a first cell and a second cell associated with a terminal device, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal; a second determining module for determining a first signal strength of the first frequency band signal and a second signal strength of the second frequency band signal; a third determining module for determining a first communication load level corresponding to the first cell and a second communication load level corresponding to the second cell; a fourth determining module for determining an inter-frequency handover threshold based on the magnitude relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal; and a triggering module for triggering the terminal device to perform cell handover or cell reselection based on the magnitude relationship, the inter-frequency handover threshold, the first signal strength, and the second signal strength.

[0007] A third aspect of this disclosure provides an electronic device, including: a processor; and a memory for storing processor-executable instructions; wherein the processor is configured to execute instructions to implement a cross-band load balancing method.

[0008] A fourth aspect of this disclosure provides a computer-readable storage medium that, when instructions in the computer-readable storage medium are executed by a processor of an electronic device, enables the electronic device to perform a cross-band load balancing method.

[0009] A fifth aspect of this disclosure provides a computer program product, including a computer program, characterized in that the computer program is executed by a processor using a cross-band load balancing method.

[0010] The inter-frequency band load balancing method, apparatus, electronic device, storage medium, and computer program product proposed in this embodiment have at least the following beneficial effects: First, a first cell and a second cell related to the terminal device are determined, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal. Then, a first signal strength of the first frequency band signal and a second signal strength of the second frequency band signal are determined. Next, a first communication load level corresponding to the first cell and a second communication load level corresponding to the second cell are determined. Then, based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal, an inter-frequency handover threshold is determined. Finally, based on the relationship, the inter-frequency handover threshold, the first signal strength, and the second signal strength, the terminal device is triggered to perform cell handover or cell reselection. Thus, the inter-frequency handover threshold corresponding to achieving load balancing can be determined efficiently and accurately, thereby enabling cell load balancing based on the inter-frequency handover threshold. Furthermore, this solves the technical problem in the prior art where the configuration of inter-frequency handover and reselection thresholds relies excessively on expert experience, resulting in low efficiency and an inability to quickly achieve load balancing.

The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0019] It should be noted that the execution subject of the inter-frequency band load balancing method in this embodiment can be an inter-frequency band load balancing device. This device can be implemented by software and / or hardware. This device can be configured in an electronic device, which may include, but is not limited to, a terminal, a server, etc.

[0020] It should be noted that the acquisition, storage, use, and processing of information in this disclosed technical solution comply with the relevant provisions of national laws and regulations and do not violate public order and good morals.

[0021] Figure 1 This is a flowchart illustrating a cross-band load balancing method according to the first embodiment of this disclosure, as shown below. Figure 1 As shown, the method includes:

[0022] S101: Determine the first cell and the second cell associated with the terminal device, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal.

[0023] The first cell associated with the terminal device can be the serving cell of the terminal device or a neighboring cell of the serving cell, without any restrictions.

[0024] The second cell associated with the terminal device can be the serving cell of the terminal device or a neighboring cell of the serving cell; there are no restrictions on this.

[0025] The first cell uses the first frequency band signal, which can be, for example, the F band signal (1880-1920) Hz. The second cell uses the second frequency band signal, which can be, for example, the D band signal (2570-2620). The D and F bands mainly cover the outdoors. The D band mainly absorbs traffic and has a higher priority. The F band, as an effective supplement to the D band signal, provides a wider coverage area and has a lower priority.

[0026] S102: Determine the first signal strength of the first frequency band signal and the second signal strength of the second frequency band signal.

[0027] Wherein, the first signal strength of the first frequency band signal refers to the reference signal received power (RSRP) of the first frequency band signal, and the second signal strength of the second frequency band signal refers to the reference signal received power (RSRP) of the second frequency band signal.

[0028] In this embodiment of the disclosure, the determination of the first signal strength of the first frequency band signal and the second signal strength of the second frequency band signal can be achieved using Measurement Report Original (MRO) data from the first and second cells. MRO data primarily originates from the terminal and base station, as well as measurement statistics calculated during radio resource management. The original measurement data is directly reported to the Operation and Maintenance Center-Radio (OMC-R) for storage in sample data format, ultimately generating an MRO file. Each sampling point mainly includes reference signal received power, reference signal received quality, timing advance, base station received interference power, uplink packet loss rate, and downlink packet loss rate. The RSRP (Reference Signal Received Power) is then determined from the MRO data corresponding to the first cell as the first signal strength, and the RSRP is determined from the MRO data corresponding to the second cell as the second signal strength.

[0029] S103: Determine the first communication load level corresponding to the first cell and the second communication load level corresponding to the second cell.

[0030] When the cell utilization, number of users, and traffic exceed the defined thresholds, the cell is considered to have a high communication load (high load).

[0031] In this embodiment of the disclosure, the communication load level of the cell can be determined by combining the total uplink and downlink traffic, the number of successfully established Evolved Radio Access Bearer (E-RAB) connections, the number of Radio Resource Control (RRC) connections with data transmission, uplink utilization PUSCH, downlink utilization PDSCH, downlink utilization PDCCH, uplink traffic (GB), downlink traffic (GB), standard, bandwidth, etc. The high load definitions for different standards and bandwidths are shown in the table below:

[0032] Table 1: High-load scenarios with standard = Frequency Division Duplex (FDD) FDD1800 and bandwidth = 20M are defined as follows:

[0033]

[0034] Table 2: High load is defined for scenarios with standard = FDD1800 and bandwidth = 15M as follows:

[0035]

[0036] Table 3: High load definition for scenarios with standard = FDD900 and bandwidth = 10M is as follows:

[0037]

[0038] Table 4: High load definition for scenarios with standard = FDD900 and bandwidth = 5M is as follows:

[0039]

[0040]

[0041] Table 5: High load scenarios with standard = TDD and bandwidth = 20M are defined as follows:

[0042]

[0043] Table 6: High load is defined for scenarios with standard = TDD and bandwidth = 15M as follows:

[0044]

[0045] Table 7: High load is defined for scenarios with standard = TDD and bandwidth = 10M as follows:

[0046]

[0047] In this embodiment of the disclosure, the utilization rate, standard, bandwidth, number of users, traffic and other data of the first cell and the second cell can be determined respectively. Then, the communication load level corresponding to the cell can be obtained by querying Tables 1-7 above in combination with the aforementioned data. Then, the first communication load level of the first cell and the second communication load level of the second cell can be combined to trigger the execution of the subsequent inter-frequency band load balancing method. For details, please refer to the following embodiments.

[0048] S104: Determine the inter-frequency handover threshold based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal.

[0049] Among them, the inter-frequency handover threshold can be used to assist in determining the cell handover threshold and cell reselection threshold of the terminal equipment, and there are no restrictions on it.

[0050] In this embodiment of the disclosure, after determining the first communication load level corresponding to the first cell and the second communication load level corresponding to the second cell, the inter-frequency handover threshold can be determined based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal.

[0051] Optionally, in some embodiments, determining the inter-frequency handover threshold based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal may involve determining the total number of sampling points, the number of first carriers corresponding to the cells covered by the first frequency band signal, and the number of second carriers corresponding to the cells covered by the second frequency band signal. When the first communication load level is higher than the second communication load level, a first formula is used to process the total number of sampling points, the number of first carriers, and the number of second carriers to obtain the first number of sampling points required for the first frequency band signal. When the first communication load level is lower than the second communication load level, a second formula is used to process the total number of sampling points, the number of first carriers, and the number of second carriers to determine the second number of sampling points required for the second frequency band signal. The inter-frequency handover threshold is then determined based on either the first or second sampling point number.

[0052] In this embodiment of the disclosure, in order to balance the D+F scenario, combined with MRO sampling, the sampling of high-frequency load points accounts for 40% and low-frequency load points accounts for 60% to output the start test of D / F handover and A5 related thresholds, thereby achieving cell load balancing.

[0053] In other words, in this embodiment of the present disclosure, when the first communication load level of the first frequency band signal F is higher than the second communication load level, the number of first sampling points required for the F frequency band can be determined based on the first formula.

[0054] Optionally, in some embodiments, the first formula is:

[0055] Number of first sampling points = (40% / (60% * number of second carriers + number of first carriers * 40%) * total number of sampling points) * number of first carriers.

[0056] In other words, in this embodiment of the present disclosure, when the second communication load level of the second frequency band signal is higher than the first communication load level, the number of second sampling points required for the D frequency band can be determined based on the second formula.

[0057] Optionally, in some embodiments, the second formula is:

[0058] Number of first sampling points = (40% / (60% * number of first carriers + number of second carriers * 40%) * total number of sampling points) * number of second carriers.

[0059] Optionally, in some embodiments, determining the inter-frequency handover threshold based on the first number of sampling points or the second number of sampling points may involve: when the first communication load level is higher than the second communication load level, if the signal strength value corresponding to the first frequency band signal is less than -100dBm, accumulating the number of sampling points corresponding to the signal strength value to obtain a first number, and then determining a first difference between the first number of sampling points and the first number; if the signal strength value corresponding to the second frequency band signal is less than -108dBm, accumulating the number of sampling points corresponding to the signal strength value to obtain a second number; determining a second difference between the first difference and the second number; and, starting from -47dBm, determining a signal strength value from the multiple signal strength values ​​corresponding to the first frequency band signal whose number of sampling points is greater than the second difference, and using the signal value whose number of sampling points is greater than the second difference as the inter-frequency handover threshold.

[0060] In other words, in this embodiment of the present disclosure, in the F high load scenario, the inter-frequency switching threshold is the first value of the RSRP interval selected from the sampling points summarized in the F band starting from -47dBm, which satisfies (the number of first sampling points - the number of sampling points reserved in F (F band sampling points below -100dBm) - the number of sampling points switched from the D weak field to F (D band sampling points below -108dBm)).

[0061] Optionally, in some embodiments, determining the inter-frequency handover threshold based on the first number of sampling points or the second number of sampling points may be achieved when the first communication load level is lower than the second communication load level. This can be done by determining a signal strength value from multiple signal strength values ​​corresponding to the second frequency band signal, starting from -47dBm, where the number of sampling points is greater than the number of second sampling points, and using the signal strength value with the greater number of sampling points as the inter-frequency handover threshold.

[0062] In other words, in this embodiment of the present disclosure, in the high-load scenario of D, the inter-frequency switching threshold is the first value of the RSRP interval value that is selected from the sampling points of the D frequency band summarizing starting from -47dBm and satisfying (greater than) the second number of sampling points.

[0063] S105: Based on the size relationship, inter-frequency handover threshold, first signal strength and second signal strength, trigger the terminal device to perform cell handover or cell reselection.

[0064] In this embodiment of the disclosure, after determining the inter-frequency handover threshold based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal, the terminal device can be triggered to perform cell handover or cell reselection based on the relationship, the inter-frequency handover threshold, the first signal strength, and the second signal strength. This can achieve cell load balancing and improve cell communication performance.

[0065] In some embodiments, based on the magnitude relationship, the inter-frequency handover threshold, the first signal strength, and the second signal strength, the terminal device is triggered to perform cell handover or cell reselection. This can be triggered when the first communication load is higher than the second communication load, and when the first signal strength and the second signal strength meet the inter-frequency handover threshold, by switching or reselecting the terminal device's serving cell from the first cell to the second cell; or when the first communication load is lower than the second communication load, and when the first signal strength and the second signal strength meet the inter-frequency handover threshold, by switching or reselecting the terminal device's serving cell from the second cell to the first cell.

[0066] In this embodiment of the disclosure, by determining the first cell and the second cell associated with the terminal device, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal, then determining the first signal strength of the first frequency band signal and the second signal strength of the second frequency band signal, then determining the first communication load level corresponding to the first cell and the second communication load level corresponding to the second cell, then determining the inter-frequency handover threshold based on the relationship between the first and second communication load levels, the first frequency band signal and the second frequency band signal, and then triggering the terminal device to perform cell handover or cell reselection based on the relationship, the inter-frequency handover threshold, the first signal strength and the second signal strength, it is possible to efficiently and accurately determine the inter-frequency handover threshold corresponding to achieve load balancing, thereby enabling cell load balancing based on the inter-frequency handover threshold.

[0067] Figure 2 This is a flowchart illustrating a cross-band load balancing method according to a second embodiment of the present disclosure, as shown below. Figure 2 As shown, the method includes:

[0068] S201: Determine the first cell and the second cell associated with the terminal equipment, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal.

[0069] S202: Determine the first signal strength of the first frequency band signal and the second signal strength of the second frequency band signal.

[0070] S203: Determine the first communication load level corresponding to the first cell and the second communication load level corresponding to the second cell.

[0071] S204: Determine the inter-frequency handover threshold based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal.

[0072] For a detailed description of S201-S204, please refer to the above embodiments, which will not be repeated here.

[0073] S205: If the first communication load level is higher than the second communication load level, and the first signal strength is greater than the inter-frequency handover threshold, and the second signal strength is less than the first threshold, then the terminal device's serving cell is switched from the first cell to the second cell.

[0074] In this embodiment, when the first communication load level is higher than the second communication load level, since the load of F is higher, some sampling points of F need to be switched to D. Therefore, the start-up and decision threshold of F need to be adjusted to make it easier for F to switch to D. The switching sampling interval is mainly concentrated between the start of F and D above -105dBm, ensuring that the user quality is better when switched to D, and reserving the sampling points below -105dBm for F. Since the load of D is lower, the switching event of D needs to be delayed to ensure that the sampling points of D above -108dBm do not switch to F (better quality area), the sampling points above -108dBm are reserved for D, and the area below -108dBm is switched to F (deep coverage area).

[0075] The first threshold can be, for example, -105dBm, and there is no restriction on it.

[0076] Therefore, when the first communication load level is higher than the second communication load level, the corresponding thresholds involved in the handover from the first cell to the second cell can be determined: set the A1 threshold of F to Q+6dB, the A2 threshold of F to Q+3dB, the RSRP at the A5 handover threshold 1 QdB, and the A5 handover threshold 2 to -105dBm. Values ​​below -105dBm are reserved for F.

[0077] In other words, in this embodiment of the present disclosure, when the first signal strength is greater than the inter-frequency handover threshold and the second signal strength is less than -105dBm, the serving cell of the terminal device can be switched from the first cell to the second cell.

[0078] S206: If the first communication load level is higher than the second communication load level, and the first signal strength is greater than the second threshold, and the second signal strength is less than the third threshold, then the terminal device's serving cell is switched from the second cell to the first cell.

[0079] The second threshold can be, for example, -108dBm, and the third threshold can be, for example, -124dBm, without any restrictions.

[0080] Therefore, when the first communication load level is higher than the second communication load level, the corresponding thresholds involved in the handover from the second cell to the first cell can be determined as follows: A1 is set to -102dBm, A2 is set to -105dBm, A51 threshold is set to -108dBm, which is used to reserve sampling points in the existing network that are higher than -108dBm for D, and A5 handover threshold 2 is set to the minimum value of the specification -124dBm.

[0081] In other words, in this embodiment of the present disclosure, when the first signal strength is greater than -108dBm and the second signal strength is less than -124dBm, the serving cell of the terminal device can be switched from the second cell to the first cell.

[0082] S207: If the first communication load level is lower than the second communication load level, and the first signal strength is greater than the first threshold, and the second signal strength is less than the inter-frequency handover threshold, then the serving cell of the terminal device is switched from the first cell to the second cell.

[0083] In this embodiment, because the load of F is low, the existing number of sampling points of F is retained and not switched to D (all sampling of F is retained for itself). Therefore, the switching threshold of A5 1 of F is set according to the minimum value of the switching event in the provincial standard. Because the load of D is high, in order to ensure the balance of D / F, some sampling points of D need to be switched to F. Therefore, the start-up and decision threshold of D need to be adjusted to make it easier for D to switch to F.

[0084] The first threshold can be, for example, -110dBm, and there is no restriction on it.

[0085] Therefore, when the first communication load level is lower than the second communication load level, the corresponding thresholds involved in the handover from the first cell to the second cell can be determined: set A1 of D to Q+6dB, A2 to Q+3dB, A5 1 handover threshold Q, and A5 handover threshold 2 to the minimum value of the specification -124dBm.

[0086] In other words, in this embodiment of the present disclosure, when the first communication load level is lower than the second communication load level, the first signal strength is greater than -110dBm, and the second signal strength is less than the inter-frequency handover threshold Q, the terminal device's serving cell is switched from the first cell to the second cell.

[0087] S208: If the first communication load level is lower than the second communication load level, and the first signal strength is greater than the inter-frequency handover threshold, and the second signal strength is less than the third threshold, then the terminal device's serving cell is switched from the second cell to the first cell.

[0088] The third threshold can be, for example, -124dBm, and there is no restriction on it.

[0089] Therefore, when the first communication load level is lower than the second communication load level, the corresponding thresholds involved in the handover from the second cell to the first cell can be determined: set A1 of D to Q+6dB, A2 to Q+3dB, and A5 1 handover threshold Q and A5 handover threshold 2 to the minimum value of the specification -124dBm.

[0090] In other words, in this embodiment of the present disclosure, if the first communication load level is lower than the second communication load level, the first signal strength is greater than the inter-frequency handover threshold Q, and the second signal strength is less than -124dBm, then the serving cell of the terminal device is switched from the second cell to the first cell.

[0091] In this embodiment, by determining a first cell and a second cell associated with the terminal device, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal, a first signal strength of the first frequency band signal and a second signal strength of the second frequency band signal are determined. Then, a first communication load level corresponding to the first cell and a second communication load level corresponding to the second cell are determined. Based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal, an inter-frequency handover threshold is determined. If the first communication load level is higher than the second communication load level, the first signal strength is greater than the inter-frequency handover threshold, and the second signal strength is less than a first threshold, then the serving cell of the terminal device is triggered to be switched from the first cell to the second cell. When the signal strength is higher than the second communication load level, and the first signal strength is greater than the second threshold, and the second signal strength is less than the third threshold, the serving cell of the terminal device is switched from the second cell to the first cell. Then, when the first communication load level is lower than the second communication load level, and the first signal strength is greater than the first threshold, and the second signal strength is less than the inter-frequency handover threshold, the serving cell of the terminal device is switched from the first cell to the second cell. Then, when the first communication load level is lower than the second communication load level, and the first signal strength is greater than the inter-frequency handover threshold, and the second signal strength is less than the third threshold, the serving cell of the terminal device is switched from the second cell to the first cell. Thus, the cell handover timing can be accurately determined based on the inter-frequency handover threshold, thereby triggering cell handover in a timely manner and achieving load balancing.

[0092] Figure 3 This is a flowchart illustrating a cross-band load balancing method according to a third embodiment of this disclosure, as shown below. Figure 3 As shown, the method includes:

[0093] S301: Determine the first cell and the second cell associated with the terminal device, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal.

[0094] S302: Determine the first signal strength of the first frequency band signal and the second signal strength of the second frequency band signal.

[0095] S303: Determine the first communication load level corresponding to the first cell and the second communication load level corresponding to the second cell.

[0096] S304: Determine the inter-frequency handover threshold based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal.

[0097] For a detailed description of S301-S304, please refer to the above embodiments, which will not be repeated here.

[0098] S305: If the first communication load level is higher than the second communication load level, and the second signal strength is greater than the first threshold, then the serving cell of the terminal device is reselected from the first cell to the second cell.

[0099] The first threshold can be, for example, -105dBm, and there is no restriction on it.

[0100] Therefore, in this embodiment of the present disclosure, when the first communication load level is higher than the second communication load level and the second signal strength is greater than -105dBm, the terminal device's serving cell can be reselected from the first cell to the second cell.

[0101] S306: If the first communication load level is higher than the second communication load level, and the third difference between the first signal strength and the second signal strength is greater than the difference threshold, then the serving cell of the terminal device is reselected from the second cell to the first cell.

[0102] The difference threshold can be, for example, 10 dBm, and there is no restriction on it.

[0103] That is to say, in this embodiment of the present disclosure, when the first communication load level is higher than the second communication load level and the third difference between the first signal strength and the second signal strength is greater than 10 dBm, the terminal device's serving cell can be reselected from the second cell to the first cell.

[0104] S307: If the first communication load level is lower than the second communication load level, and the second signal strength is greater than the inter-frequency handover threshold, then the serving cell of the terminal device is reselected from the first cell to the second cell.

[0105] In other words, in this embodiment of the present disclosure, if the first communication load level is lower than the second communication load level and the second signal strength is greater than the inter-frequency handover threshold, the serving cell of the terminal device may be reselected from the first cell to the second cell.

[0106] S308: If the first communication load level is lower than the second communication load level, and the third difference between the first signal strength and the second signal strength is greater than the difference threshold, then the serving cell of the terminal device is reselected from the second cell to the first cell.

[0107] The difference threshold can be, for example, 10 dBm, and there is no restriction on it.

[0108] That is to say, in this embodiment of the present disclosure, when the second communication load level is higher than the first communication load level and the fourth difference between the second signal strength and the first signal strength is greater than 10 dBm, the terminal device's serving cell can be reselected from the first cell to the second cell.

[0109] In this embodiment, by determining a first cell and a second cell related to the terminal device, wherein the first cell uses a first frequency band signal and the second cell uses a second frequency band signal, a first signal strength of the first frequency band signal and a second signal strength of the second frequency band signal are determined. Then, a first communication load level corresponding to the first cell and a second communication load level corresponding to the second cell are determined. Based on the relationship between the first and second communication load levels, the first frequency band signal, and the second frequency band signal, an inter-frequency handover threshold is determined. When the first communication load level is higher than the second communication load level and the second signal strength is greater than a first threshold, the serving cell of the terminal device is reselected from the first cell to the second cell. When the load level is lower than the second communication load level and the third difference between the first signal strength and the second signal strength is greater than the difference threshold, the serving cell of the terminal device is triggered to be reselected from the second cell to the first cell. When the first communication load level is lower than the second communication load level and the second signal strength is greater than the inter-frequency handover threshold, the serving cell of the terminal device is triggered to be reselected from the first cell to the second cell. When the first communication load level is lower than the second communication load level and the third difference between the first signal strength and the second signal strength is greater than the difference threshold, the serving cell of the terminal device is triggered to be reselected from the second cell to the first cell. In this way, the cell reselection timing can be accurately determined based on the inter-frequency handover threshold, thereby triggering cell reselection in a timely manner, achieving load balancing, and further optimizing network performance and stability.

[0135] If the first communication load level is higher than the second communication load level, and the first signal strength is greater than the second threshold, and the second signal strength is less than the third threshold, then the terminal device's serving cell will be switched from the second cell to the first cell.

[0136] If the first communication load level is lower than the second communication load level, and the first signal strength is greater than the first threshold, and the second signal strength is less than the inter-frequency handover threshold, then the terminal device's serving cell will be switched from the first cell to the second cell.

[0138] In some embodiments of this disclosure, the trigger module 405 is further configured to:
