Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an interference management method, device and storage medium. Background Art

[0002] The fifth generation mobile communication technology (5G) base station supports more channels, uses large-scale antenna arrays, and supports massive antenna technology (massive multiple-input multiple-output, massive MIMO) to greatly improve network performance. 5G base stations that support massive MIMO technology can transmit multiple beams, and different beams cover different areas. The multi-beam transmission method can meet the coverage requirements of different scenarios and improve the spatial coverage performance of the network. When each terminal (User Equipment, UE) connected to the 5G base station accesses the network, it can select and access the beam with the strongest signal strength through beam measurement.

[0003] In order to avoid interference between beams, the prior art controls the coverage range of the beams by presetting the coverage parameters of the beams, and spatially staggers the beams of the same frequency to avoid mutual interference.

[0004] In general technology, when a UE selects an access beam, it selects the beam to be accessed based on the beam signal strength measured by a single UE. This method may cause different UEs in similar locations or in the same geographical area to access different beams, causing some UEs in similar locations to be scattered on different beams. In this way, it is difficult for 5G base stations to avoid interference between different beams by staggering them in space, reducing the effect of interference suppression. Summary of the invention

[0087] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0088] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0089] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0090] As described in the background technology, 5G base stations support more channels, use large-scale antenna arrays, and support massive MIMO technology to significantly improve network performance.

[0091] Massive MIMO means that the transmitter and receiver use multiple transmit antennas and receive antennas to send and receive signals respectively. Through beamforming technology, the phase of the antenna array is adaptively adjusted to form multiple energy-concentrated narrow beams pointing to a specific area, thereby improving the system channel capacity and signal coverage.

[0092] 5G base station equipment can transmit multiple beams, and different beams cover different areas. Through multi-beam transmission, it can meet the coverage requirements of different scenarios and improve the spatial coverage performance of the network. When each terminal accesses the network, it selects and accesses the beam with the strongest signal strength through beam measurement.

[0093] In order to improve the efficiency of spectrum utilization, mobile communication networks usually adopt frequency reuse networking. Adjacent beams will use the same spectrum resources, resulting in mutual interference between different beams, affecting network performance. For the downlink direction, the downlink signal of the disturbing beam falls into the terminal receiver under the disturbed beam, causing downlink interference to the terminal under the disturbed beam.

[0094] In order to avoid interference between beams, the prior art controls the coverage range of the beams by presetting the coverage parameters of the beams, and spatially staggers the beams of the same frequency to avoid mutual interference.

[0095] In general technology, when a terminal selects an access beam, it selects the beam to be accessed based on the beam signal strength measured by a single terminal. This may cause different terminals in similar locations and in the same geographical area to access different beams. The terminals are scattered on different beams, and it is difficult to avoid interference between different beams by spatially staggering them. The interference suppression effect is limited, and the goal of suppressing interference between beams cannot be achieved.

[0096] In response to the above problems, an embodiment of the present application provides an interference management method, which can obtain the location information of multiple terminals in a preset area, and divide the multiple terminals into at least one terminal cluster based on the location information. Then, at least one beam corresponding to at least one terminal cluster can be determined, and for each terminal in the multiple terminals, each terminal is controlled to access the beam corresponding to the terminal cluster to which it belongs. In this way, the present application can reduce the number of beams accessed by terminals in the preset area and improve the interference suppression effect between beams.

[0097] The interference management method is applicable to an interference management system. The interference management system can be applicable to a preset area. The preset area is an arbitrarily defined area in the network, including at least one base station. Each base station can support at least one beam (supporting beamforming technology). Different beams cover different spatial areas.

Base station 1 is configured with beam 1 and beam 2, and base station 2 is configured with beam 3 and beam 4. There is at least one terminal in the preset area. At least one terminal can form a terminal cluster. Figure 1 A target terminal cluster is taken as an example for explanation.

[0100] The interference management module is used to implement the control function of interference coordination between beams in the preset area, and there is a message interaction interface between the base stations where each beam in the preset area is located. The interference management module is a functional entity, and the physical entity can be located in a base station, core network equipment, base station operation and maintenance platform in the preset area, or in an independent physical device.

[0101] Optionally, the terminal may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. The wireless terminal may communicate with one or more core networks via a radio access network (RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network, such as a mobile phone, tablet computer, laptop computer, netbook, personal digital assistant (PDA).

The server may be a server in a server cluster (composed of multiple servers), a chip in the server, a system on chip in the server, or a virtual machine deployed on a physical machine, which is not limited in the present application.

[0108] In a possible implementation, the memory 22 may exist independently of the processor 21, and the memory 22 may be connected to the processor 21 via a bus 24 to store instructions or program codes. When the processor 21 calls and executes the instructions or program codes stored in the memory 22, the interference management method provided in the following embodiments of the present application can be implemented.

[0109] In the embodiment of the present application, for the interference management module 102, the software programs stored in the memory 22 are different, so the functions implemented by the interference management module are different.

[0125] The preset historical time is a time period before the preset first cycle, which includes a number of unit time periods, and the length of each unit time period is the same as the preset second cycle.

[0126] Each base station in the preset area can obtain the location information of all terminals accessing the base station according to the preset second period, and send a terminal location information report message to the interference management module, which carries the location information of each terminal in the preset historical time.

[0127] After acquiring the location information of multiple terminals in the preset area, the interference management module may divide all the terminals in the preset area into terminal clusters using a preset algorithm and determine terminal cluster parameters.

[0128] The preset area may include at least one terminal cluster, and different terminal clusters may be uniquely distinguished by a terminal cluster identifier.

[0129] The terminal cluster parameter includes a terminal cluster identifier and an identifier list of each terminal included in the terminal cluster.

[0130] The preset algorithm is used to classify terminals with similar location characteristics into the same terminal cluster, so that the terminals in the same terminal cluster are located in the same geographical area, and the signal strength of each received beam and the interference between beams are similar.

[0131] S402: The interference management module performs a first operation on at least one terminal cluster to obtain at least one beam corresponding to the at least one terminal cluster.

[0132] The first operation includes: obtaining target beam measurement information of each target terminal in the target terminal cluster. The target beam measurement information includes: a signal strength value and a signal quality value. According to the target beam measurement information, a target beam corresponding to the target terminal cluster is determined. The target terminal cluster is any one of at least one terminal cluster; the target terminal is any one terminal in the target terminal cluster.

[0133] Optionally, the interference management module obtains target beam measurement information of each target terminal in the target terminal cluster, including:

[0134] The interference management module receives beam measurement information indication messages sent by multiple base stations in the preset area; the beam measurement information indication message includes: beam measurement information corresponding to terminals served by multiple base stations and identifiers of multiple base stations; the beam measurement information indication message is sent by multiple base stations after receiving beam measurement report messages sent by multiple terminals in the preset area; the beam measurement report message includes beam measurement information; the beam measurement information includes terminal identifier, beam frequency, beam identifier and corresponding beam signal strength and signal quality;

[0135] If a terminal belongs to the target terminal cluster, the interference management module determines the beam measurement information corresponding to the terminal as the target beam measurement information.

[0136] Specifically, each terminal within the preset area can send a beam measurement report message to multiple base stations according to a preset second period, which carries the beam measurement information corresponding to each terminal.

[0137] The beam measurement information includes the terminal identifier, beam frequency, beam identifier and the corresponding beam signal strength and signal quality. One beam measurement information corresponds to one terminal identifier, and one beam measurement information includes at least one beam identifier and the corresponding beam signal strength and signal quality.

[0138] The signal strength of a beam is defined as the reference signal power value of the beam measured by the terminal, and the signal quality of a beam is defined as the ratio of the reference signal of the beam measured by the terminal to the interference noise.

[0139] The preset second period is a measurement period of the terminal, and its length is shorter than the preset first period length.

[0140] After receiving the beam measurement report message, multiple base stations send a beam measurement information indication message to the interference management module, which carries the beam measurement information corresponding to the terminal and multiple base station identifiers.

[0141] After receiving multiple beam measurement information sent by multiple base stations, the interference management module can determine the target beam measurement information corresponding to the target terminal cluster.

[0142] The target beam measurement information includes beam measurement information corresponding to at least one target terminal in the target terminal cluster. The target beam information can be determined according to the target terminal cluster parameters.

[0143] Specifically, if a terminal belongs to a target terminal cluster, the beam measurement information corresponding to the terminal belongs to the target beam measurement information.

[0144] The target terminal cluster is any terminal cluster in the preset area. The target terminal is any terminal in the target terminal cluster.

[0145] S403: The interference management module controls, for each of the multiple terminals, a terminal to access a beam corresponding to a terminal cluster to which the terminal belongs.

[0146] Herein, a terminal is any one of multiple terminals.

[0147] Specifically, the interference management module may send a beam access request message to a base station accessed by each target terminal in the target terminal cluster, which carries a target beam identifier and target terminal cluster parameters.

[0148] The base station accessed by each target terminal sends a beam access indication message to each target terminal, which carries a target beam identifier.

[0149] After receiving the beam access indication message, each target terminal accesses the target beam.

[0150] It can be seen from the above description that each terminal generally accesses the beam with the largest signal strength based on the measurement of the signal strength of each beam. This will cause different terminals in the same area to access different beams, increase the number of beams accessed by terminals in the area, and increase inter-beam interference. In this application, after the interference management module determines the terminal cluster and the corresponding target beam, it controls the terminals in the same terminal cluster to access the same target beam by sending messages, which can reduce the number of beams accessed by each terminal in the terminal cluster and improve the interference suppression effect between beams.

[0151] In one embodiment, in combination Figure 4 ,like Figure 5 As shown, after the interference management module controls each terminal among the multiple terminals to access a beam corresponding to a terminal cluster to which the terminal belongs, it also includes:

[0152] S501. The interference management module performs a second operation on at least one terminal cluster to obtain at least one interference beam corresponding to the at least one terminal cluster.

[0153] The second operation includes: determining at least one downlink interference beam according to the target beam measurement information of each target terminal in the target terminal cluster. Determining the average value of the average signal strength value of at least one downlink interference beam as the downlink interference value of the target terminal cluster. If the downlink interference value of the target terminal cluster is greater than a preset interference threshold, determining the target interference beam corresponding to the target terminal cluster according to the edge service load of each downlink interference beam.

[0154] Specifically, the interference management module may determine the downlink interference beam according to the target beam measurement information. Then, the interference management module may determine the downlink interference value of the target terminal cluster.

[0155] In one practicable manner, the interference management module may first determine the average value of the average signal strength value of at least one downlink interfering beam as the downlink interference value of the target terminal cluster.

[0156] Specifically, the downlink interference value may be defined as an average value of average signal strength values ​​of at least one downlink disturbing beam.

[0157] After each terminal in the target terminal cluster accesses the target beam, since there may be multiple beams in the area where the target terminal cluster is located, the downlink interference beam and downlink interference value causing interference to the target terminal cluster are determined by obtaining the beam measurement information of each terminal in the target terminal cluster.

[0158] The downlink interference value is used to reflect the magnitude of the downlink interference suffered by the target terminal cluster. When the downlink interference is large, the target interference beam is further determined and its coverage parameters are adjusted to reduce the interference suffered by each terminal in the target terminal cluster.

[0159] If the downlink interference value of the target terminal cluster is greater than a preset interference threshold, and the edge service load of the downlink disturbing beam is less than a preset load threshold, the downlink disturbing beam is determined as the target disturbing beam.

[0160] Correspondingly, if the downlink interference value of the target terminal cluster is less than or equal to the preset interference threshold, or the edge service load of the downlink interference beam is greater than or equal to the preset load threshold, there is no need to determine the target interference beam.

[0161] S502: The interference management module sends a beam adjustment request message.

[0162] The beam adjustment request message is used to request at least one disturbing beam to adjust the coverage parameter of at least one disturbing beam according to a preset rule.

[0163] Specifically, the interference management module may send a beam adjustment request message to the target base station where the target interfering beam is located, wherein the message carries the target interfering beam identifier.

[0164] After receiving the beam adjustment request message, the target base station can adjust the coverage parameters of the target interference beam according to the preset rules.

[0165] The coverage parameters of the beam include at least one of the parameters such as the width of the beam and the transmission power.

[0166] The beam width can be defined as the angle between two points on both sides of the maximum radiation direction of the main lobe of the beam where the radiation intensity decreases by 3dB. The smaller the lobe width, the better the beam directivity and the stronger the anti-interference ability.

[0167] The beam transmission power is the power value allocated to the beam by the base station where the beam is located. The greater the beam transmission power, the longer the coverage distance, and the stronger the interference to the terminals under other adjacent beams.

[0168] In one embodiment, the preset rules include:

[0169] If the width of the target interference beam is not less than the preset minimum width and the transmit power is not less than the preset minimum power, the width of the target interference beam is reduced by the preset angle step value and / or the transmit power of the target interference beam is reduced by the preset power step value.

[0170] If the average signal strength value corresponding to the adjusted target disturbing beam is greater than or equal to the first signal strength threshold, the target disturbing beam continues to be adjusted until the average signal strength value corresponding to the adjusted target disturbing beam is less than the first signal strength threshold.

[0171] Exemplarily, if the width of the current target interference beam is not less than a preset minimum width, and the transmit power is not less than a preset minimum power, the width of the target interference beam is reduced by a preset angle step value, and / or the transmit power of the target interference beam is reduced by a preset power step value.

[0172] The target base station reacquires the target beam measurement information corresponding to the target terminal cluster in the next second period, which includes the beam measurement information corresponding to at least one target terminal in the target terminal cluster. The beam measurement information corresponding to each target terminal includes at least one beam identifier and a corresponding beam signal strength value.

[0173] The target base station determines the average signal strength value of the target disturbing beam according to the target beam measurement information, that is, the average value of the signal strength value of the target disturbing beam measured by at least one target terminal in the target beam measurement information.

[0174] The target base station compares the average signal strength value of the target jamming beam with the preset first signal strength threshold. If the average signal strength value of the target jamming beam is not greater than the preset first signal strength threshold, the current beam width and beam transmission power are determined as the coverage parameters of the adjusted target jamming beam.

[0175] Correspondingly, if the average signal strength value of the target disturbing beam is greater than the preset first signal strength threshold, the target disturbing beam continues to be adjusted until the average signal strength value corresponding to the adjusted target disturbing beam is less than the first signal strength threshold.

[0176] In general technologies, the coverage parameters of each beam and the corresponding coverage range are pre-set and cannot be dynamically adjusted based on changes in terminal position and real-time interference conditions. It is difficult to meet the interference suppression requirements of the terminal in real time, affecting the service performance of the terminal.

[0177] In the present application, the target base station adjusts the coverage parameters of the target interference beam according to a preset step size until the average signal strength value of the beam is no greater than the preset first signal strength threshold. By adjusting the coverage parameters of the target interference beam, the average signal strength value of the target interference beam is reduced, thereby reducing interference to the target terminal cluster.

[0178] In one embodiment, in combination Figure 5 ,like Figure 6 As shown, in the above S401, the interference management module obtains the location information of multiple terminals in a preset area, and divides the multiple terminals into at least one terminal cluster based on the location information, specifically including:

[0179] S601. An interference management module obtains location information of multiple terminals in a preset area in each unit time period within a preset historical time.

[0180] S602: The interference management module inputs the location information of multiple terminals in a preset area in each unit time period in a preset historical time into a clustering model to obtain at least one terminal cluster.

[0181] Specifically, the interference management module may obtain the location information of all terminals in a preset area in each unit time period in a preset historical time, and use the location information as sample data to input into a clustering model to obtain at least one terminal cluster.

[0182] Optionally, the clustering model may adopt a k-means clustering algorithm (k-means clustering algorithm, K-means), a system clustering algorithm, a density-based clustering algorithm (Density-Based Spatial Clustering of Applications with Noise, DBSCAN) and other models.

[0183] In one embodiment, in combination Figure 5 ,like Figure 7As shown, the method in which the interference management module obtains location information of multiple terminals in a preset area and divides the multiple terminals into at least one terminal cluster based on the location information specifically includes:

[0184] S701. An interference management module obtains location information of multiple terminals in a preset area in each unit time period within a preset historical time.

[0185] S702: The interference management module performs a third operation on each of the multiple terminals to obtain at least one terminal cluster.

[0186] The third operation includes: determining the distance between the first terminal and the second terminal according to the location information of the first terminal and the location information of the second terminal within a unit time period in the preset historical time. If the distance is less than the preset distance, determining the unit time period as the first unit time period. If the ratio of the number of first unit time periods to the total number of unit time periods within the preset historical time is greater than a preset ratio, determining that the first terminal and the second terminal are the same terminal cluster.

[0187] Exemplarily, the interference management module may obtain location information of all terminals in a preset area in each unit time period within a preset historical time.

[0188] In a certain unit time period within the preset historical time, if the distance between the terminal 1 and the terminal 2 is smaller than a preset third threshold, the unit time period is determined as a first unit time period.

[0189] If the ratio of the number of the first unit time periods to the total number of unit time periods within the preset historical time is greater than a preset fourth threshold, it is considered that terminal 1 and terminal 2 belong to the same terminal cluster.

[0190] The distance between terminal 1 and terminal 2 may be determined based on their location information, that is, calculated based on their longitude and latitude.

[0191] By the above Figure 6 and Figure 7 It can be seen that the interference management module is based on the location information of each terminal in the target terminal cluster in each unit time period within a preset historical time. Through a preset algorithm, it fully explores the location distribution characteristics and regularity of each terminal in a longer time range, and divides terminals with similar characteristics into the same terminal cluster, so that the terminals in the same terminal cluster are located in the same geographical area, and the signal strength of each received beam is similar to the interference between beams. Therefore, the target beam to be accessed can be selected in units of terminal clusters. By controlling the terminals in the same terminal cluster to access the target beam, the number of beams accessed by terminals in the preset area is reduced, the interference suppression effect between beams is improved, and interference management in units of terminal clusters is realized.

[0192] In one embodiment, the target beam measurement information further includes: beam frequency. In the above S402, the method in which the interference management module determines the target beam corresponding to the target terminal cluster according to the target beam measurement information specifically includes:

[0193] The interference management module determines at least one beam frequency included in at least one target beam measurement information as at least one candidate frequency.

[0194] Among them, at least one target beam measurement information corresponds one-to-one to at least one target terminal in the target terminal cluster.

[0195] Specifically, the interference management module may determine the beam frequency included in the target beam measurement information as the candidate frequency.

[0196] The interference management module determines an average signal quality value of at least one candidate frequency based on the at least one target beam measurement information.

[0197] The average signal quality value of at least one candidate frequency is an average value of the signal quality values ​​of the candidate frequency measured by at least one target terminal in at least one target beam measurement information.

[0198] Specifically, the interference management module may determine the average signal quality value of each candidate frequency according to the target beam measurement information, that is, the average value of the candidate frequency signal quality values ​​measured by at least one target terminal in the target beam measurement information.

[0199] The interference management module determines the candidate frequency with the largest average signal quality value among at least one candidate frequency as the target frequency, and determines at least one beam with at least one beam frequency being the target frequency as the candidate beam.

[0200] Specifically, the interference management module may determine the candidate frequency with the largest average signal quality value as the target frequency. Then, the interference management module may determine the beam whose beam frequency in the target beam measurement information is the target frequency as the candidate beam.

[0201] The interference management module determines average signal strength values ​​of the candidate beams, and determines the candidate beam with the largest average signal strength value as the target beam.

[0202] The average signal strength value is the average value of the candidate beam signal strength value measured by at least one target terminal in at least one target beam measurement information. Alternatively, if the candidate beam is the strongest beam of a target terminal in the target terminal cluster, a target terminal is determined as the associated terminal corresponding to the candidate beam, and the candidate beam with the largest ratio of the number of associated terminals to the total number of terminals included in the target terminal cluster is determined as the target beam. The strongest beam is the beam with the largest beam signal strength value measured by a target terminal.

[0203] In one achievable manner, when the interference management module determines the target beam corresponding to the target terminal cluster, it can determine the average signal strength value of each candidate beam, that is, the average value of the candidate beam signal strength value measured by at least one target terminal in the target beam measurement information.

[0204] Next, the interference management module may determine the candidate beam with the largest average signal strength value as the target beam.

[0205] In yet another achievable manner, the interference management module may determine the weight of each candidate beam when determining the target beam corresponding to the target terminal cluster.

[0206] The weight of the candidate beam is defined as the ratio of the number of associated terminals of the candidate beam to the total number of terminals included in the target terminal cluster.

[0207] Specifically, if the candidate beam is the strongest beam of a target terminal in the target terminal cluster, the interference management module can determine the target terminal as the associated terminal corresponding to the candidate beam. Then, the interference management module can determine the candidate beam with the largest ratio of the number of associated terminals to the total number of terminals included in the target terminal cluster as the target beam.

[0208] Among them, the strongest beam of each target terminal in the target terminal cluster can be determined according to the target beam measurement information.

[0209] Specifically, the target beam measurement information includes beam measurement information corresponding to at least one target terminal in the target terminal cluster, wherein the beam measurement information corresponding to each target terminal includes at least one beam identifier and a corresponding beam signal strength value. The interference management module can determine the beam with the largest beam signal strength value as the strongest beam of the target terminal.

[0210] From the above description, it can be seen that in this application, in a multi-beam coverage area, when a terminal accesses a beam, it is not only based on the signal strength measurement value of a single terminal, but is based on the beam signal strength and signal quality measurement values ​​of each terminal in the terminal cluster to determine the target beam to be accessed.

[0211] Specifically, the interference management module can determine the target frequency and the corresponding candidate beams based on the beam signal quality measurement values ​​of each terminal in the target terminal cluster, and further determine the target beam to be accessed from the candidate beams based on the beam signal strength measurement values ​​of each terminal in the target terminal cluster.

[0212] In this way, the present application can make the average signal quality of the target beam higher and the interference lower, and at the same time make the average signal strength of the target beam higher, thereby improving the received signal quality of each terminal in the target terminal cluster and meeting the network performance requirements of the terminal.

[0213] In one embodiment, in the above S501, the method in which the interference management module determines at least one downlink interference beam according to the target beam measurement information of each target terminal in the target terminal cluster specifically includes:

[0214] In at least one target beam measurement information, if the beam frequency of each beam in at least one beam is the same as the frequency of the target beam, and the average signal strength value of each beam is greater than a preset first signal strength threshold, the interference management module determines at least one beam as at least one downlink interference beam.

[0215] Specifically, in the target beam measurement information, if the beam frequency of a certain beam is the same as the frequency of the target beam, and the average signal strength value is greater than the preset first signal strength threshold, the interference management module determines the beam as a downlink interference beam. The average signal strength value is defined as the average value of the candidate beam signal strength values ​​measured by at least one target terminal in the target beam measurement information.

[0216] In one embodiment, in the above S501, the method in which the interference management module determines the target interference beam corresponding to the target terminal cluster according to the edge service load of each downlink interference beam specifically includes:

[0217] If the edge service load of a downlink interference beam is less than a preset load threshold, the interference management module determines a downlink interference beam as a target interference beam. Specifically, if the edge service load of a downlink interference beam is less than a preset load threshold, the interference management module can determine the downlink interference beam as a target interference beam.

[0218] The edge service load is defined as the ratio of the number of edge terminals of the beam or the number of physical resource blocks (PRBs) occupied by the edge terminals to the total number of available PRBs of the beam. The edge terminal is a terminal located in the edge coverage area of ​​the beam.

[0219] Optionally, if a terminal accessing the beam measures that the signal strength value of the beam is less than a preset second signal strength threshold, the terminal is determined as an edge terminal of the beam.

[0220] In the present application, the interference management module can determine the downlink interference beam causing interference to the target terminal cluster based on the beam measurement information of each terminal in the target terminal cluster, and determine the target interference beam to be adjusted based on the edge service load information of the beam.

[0221] After the target interference beam is adjusted, the coverage of the beam shrinks, and the signal strength received by some terminals in the edge coverage area of ​​the beam decreases, and the network performance may be affected. This application can reduce the number of terminals affected during the beam adjustment process by selecting a beam with a smaller edge service load as the target interference beam to be adjusted, thereby reducing the interference to the target terminal cluster while reducing the impact on the service performance of other terminals in the preset area, thereby ensuring the overall network performance of the preset area.
