[0033] The following describes in detail, with reference to the accompanying drawings, a method, apparatus, and storage medium for determining a terminal to be switched out according to an embodiment of the present disclosure.

[0034] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0035] The terms “first” and “second” in this disclosure and its accompanying drawings are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a particular order of objects.

[0036] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this disclosure are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus. It should be noted that in the embodiments of this disclosure, 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 this disclosure should not be construed as preferred or advantageous over other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0037] In the description of this disclosure, unless otherwise stated, "multiple" means two or more.

[0038] Currently, base stations are fundamental communication devices in modern communication networks, used to provide coverage services for mobile communication networks. However, due to the large number of base stations and the complex structure of their equipment, base station malfunctions are unavoidable.

[0039] Common base station failure types include: failures caused by excessive base station load, failures caused by base station signal transmission problems, failures caused by software problems of base station equipment, failures caused by hardware problems of base station, and failures caused by environmental interference.

[0040] For the aforementioned base station failure types, the common solution is to address the fault at the base station side only when normal base station operation is affected or the base station is completely unusable. This involves adjusting base station parameters, restarting the base station, and reconnecting related resources. This approach may have the following problems: 1. Insufficient timeliness: Often, intervention only occurs after the base station has already experienced equipment failure, malfunctions, or alarms; 2. Low efficiency: Handling base station failures requires significant manpower. Failure to quickly resolve the fault may cause network fluctuations in neighboring base stations, potentially leading to a chain reaction of failures; 3. The technical personnel handling the fault may lack sufficient expertise to accurately identify the root cause, impacting the network experience for more users. Furthermore, the base station-side processing in these methods disconnects users from the network, resulting in a degraded network experience.

[0041] To address the technical problems existing in related technologies, this disclosure provides a method for determining terminals to be handed over. When a base station fails due to excessive pressure, this method determines the terminals to be handed over from the faulty base station based on the network experience on the terminal side. The terminals to be handed over are those with a high probability of actively handing over and / or whose handover from the target base station has a minimal impact on the first terminal's service. This reduces the pressure on the base station without affecting the user's network experience, ensuring the user's network experience while handling the base station failure. The method includes: a terminal to be handed over determination device first determines the handover impact parameters of each of the multiple first terminals accessing the target base station; the handover impact parameters include at least one of the following: handover probability and dependency weight; wherein, the handover probability characterizes the probability that the first terminal is currently handing over from the target base station; the dependency weight characterizes the degree of impact on the first terminal's service when the first terminal hands over from the target base station; that is, it determines the probability that the multiple first terminals accessing the target base station actively hand over from the target base station and the degree of impact on the first terminal's service when handing over from the target base station. Furthermore, based on the handover impact parameters, the method determines the first terminal among the multiple first terminals whose handover impact parameters meet preset conditions as the terminal to be handed over. In other words, the first terminal that has the least impact on the user's network experience after being disconnected from the base station is identified as the disconnecting terminal; the base station actively disconnects the terminal that has the least impact on the network experience after being disconnected from the base station, thereby reducing the pressure on the base station and avoiding the user's network connection being disconnected due to processing performed on the base station side, thus ensuring the user's network experience.

[0042] In one possible implementation, the above-described method for determining the terminal to be switched out can be applied to the system 100 for determining the terminal to be switched out. The following, in conjunction with... Figure 1 This application provides a detailed description of a terminal to be switched out determination system 100 according to an embodiment. For example... Figure 1 As shown, Figure 1 A terminal to be switched out determination system 100 provided in this embodiment of the present disclosure includes: a target base station 101, multiple terminals 102, and a terminal to be switched out determination device 103.

[0043] Among them, multiple terminals 102 are terminals accessing the target base station 101; the terminal to be handed over determination device 103 is used to acquire the transmission data between the target base station 101 and the multiple terminals 102 when the target base station 101 fails, and determine the handover impact parameter of each terminal 102 among the multiple terminals 102 accessing the target base station 101 based on the transmission data; the handover impact parameter includes at least one of the following: handover probability and dependency weight; wherein, the handover probability is used to characterize the probability that the terminal 102 is currently handing over from the target base station 101; the dependency weight is used to characterize the degree of impact of the terminal 102 handing over from the target base station 101 on the terminal 102's service; and further determine the terminals among the multiple terminals 102 with a high probability of actively handing over from the target base station 101 and terminals whose handover from the target base station 101 has a small impact on the terminal's service as terminals to be handed over based on the handover impact parameter.

[0044] In one possible implementation, the hardware structure of the terminal to be switched out determination device 103 in the aforementioned terminal to be switched out determination system 100 includes: Figure 2 The components included in the terminal to be cut off determination device 200 shown below are described in detail below. Figure 2 Taking the terminal to be cut off determination device 200 shown as an example, the hardware structure of the terminal to be cut off determination device 103 is introduced. For example... Figure 2 As shown, the terminal to be switched out determination device 200 includes at least one processor 201, a communication line 202, and at least one communication interface 204, and may also include a memory 203. The processor 201, memory 203, and communication interface 204 can be connected via the communication line 202.

[0045] The processor 201 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement embodiments of the present disclosure, such as one or more digital signal processors (DSPs), or one or more field-programmable gate arrays (FPGAs).

[0046] Communication line 202 may include a path for transmitting information between the aforementioned components.

[0047] The communication interface 204 is used to communicate with other devices or communication networks. It can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0048] The memory 203 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium capable of including or storing desired program code having the form of instructions or data structures and accessible by a computer, but not limited thereto.

[0049] In one possible design, the memory 203 can exist independently of the processor 201, meaning the memory 203 can be an external memory of the processor 201. In this case, the memory 203 can be connected to the processor 201 via the communication line 202 to store execution instructions or application code, and its execution is controlled by the processor 201 to implement the terminal to be switched out method provided in the following embodiments of this disclosure. In another possible design, the memory 203 can also be integrated with the processor 201, meaning the memory 203 can be an internal memory of the processor 201. For example, the memory 203 can be a cache, which can be used to temporarily store some data and instruction information.

[0050] As one possible implementation, processor 201 may include one or more CPUs, for example Figure 2 CPU0 and CPU1 in the example. Alternatively, the terminal to be switched out determination device 200 may include multiple processors, such as... Figure 2 The processors 201 and 207 are included. Alternatively, the terminal to be switched out determination device 200 may also include an output device 205 and an input device 206.

[0051] The following is a detailed description of the method for determining the terminal to be switched out provided in the embodiments of this disclosure.

[0052] like Figure 3 As shown, Figure 3 The method for determining the terminal to be switched out provided in this embodiment includes the following steps S301-S302, which will be described in detail below.

[0053] S301, The terminal to be cut off determination device determines the cut-off impact parameters of each of the multiple first terminals accessing the target base station.

[0054] The handover impact parameters include at least one of the following: handover probability and dependency weight; the handover probability is used to characterize the probability that the first terminal is currently handing over from the target base station; the dependency weight is used to characterize the degree of impact on the first terminal's services when the first terminal is handing over from the target base station.

[0055] In one possible implementation, the target base station is a faulty base station. The terminal to be handed over determination device can obtain information such as the base station's operating status, hardware indicators, and software status, as well as the analysis results of the status information, through the network management system. Based on the analysis results, it can determine whether the base station is faulty, and if a fault is confirmed, further determine the type and location of the fault. It should be noted that if the target base station is faulty due to excessive user access causing overload, the terminal to be handed over determination device can determine the terminal to be handed over based on the probability of a terminal currently connected to the target base station handing over and the impact on terminal services when a terminal hands over from the target base station. This reduces the pressure on the base station and resolves the target base station fault promptly.

[0056] S302, The terminal to be cut off determination device determines the first terminal among multiple first terminals whose cutting-off influence parameters meet the preset conditions as the terminal to be cut off.

[0057] In one possible implementation, the preset conditions could be high cut-out probability and / or low dependency weight. In this way, the terminal to be cut out determination device can identify terminals with high cut-out probability and / or low dependency weight as terminals to be cut out, thereby reducing the impact of terminal cut-out.

[0058] For example, when the influencing parameter includes the cut-out probability, the preset condition includes: the cut-out probability of the first terminal is greater than a first threshold of 50%.

[0059] If the probability of the first terminal being cut off is greater than 50%, then the first terminal can be determined as the terminal to be cut off with a high probability of being cut off, so as to reduce the impact of terminal cutting off.

[0060] When the influencing parameters include dependency weights, the preset conditions include: the dependency weight of the first terminal is less than the second threshold.

[0061] If the dependency weight of the first terminal is less than the second threshold, then the first terminal can be determined as a terminal with low dependency weight to be cut off, so as to reduce the impact of terminal cutting off.

[0062] When the influencing parameters include the cut-out probability and the dependency weight, the preset conditions include: the cut-out probability of the first terminal is greater than the first threshold and the dependency weight of the first terminal is less than the second threshold.

[0063] If the cut-out probability of the first terminal is greater than 50% and the dependency weight of the first terminal is less than 1, then the first terminal can be determined as a terminal to be cut out with a high cut-out probability and a low dependency weight, so as to reduce the impact of terminal cut-out.

[0064] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The device for determining the terminal to be handed over first determines the handover impact parameters of each of the multiple first terminals accessing the target base station; that is, it determines the possibility of the multiple first terminals actively handing over to the target base station and the degree of impact on the service of the first terminal when handing over from the target base station. Furthermore, based on the handover impact parameters, it determines the first terminal among the multiple first terminals whose handover impact parameters meet preset conditions as the terminal to be handed over. That is, it determines the first terminal whose impact on the user's network experience after handing over to the base station is relatively small as the handover terminal; the base station actively hands over the terminal whose impact on the network experience is relatively small after handing over to the base station, thereby reducing the pressure on the base station and avoiding the user's network connection being disconnected due to processing performed on the base station side, thus ensuring the user's network experience.

[0065] One possible way to achieve this is by combining Figure 3 ,like Figure 4 As shown, when the handover impact parameters include the handover probability, the process of determining the handover impact parameters of each of the multiple first terminals accessing the target base station by the handover terminal determination device in the above-mentioned S301 can be specifically implemented by the following S401-S403, which will be explained in detail below.

[0066] S401, The device for determining the terminal to be handed over determines the network parameters of multiple second terminals when they access the target base station, and the network parameters of multiple second terminals when they hand over the target base station.

[0067] The second terminal is the terminal that accessed the target base station before the current time.

[0068] In one possible implementation, the network parameters of the second terminal when accessing / handing out the target base station include: the location of the second terminal when transmitting data with the target base station, the network's reference signal receiving power (RSRP), signal to interference plus noise ratio (SINR), CIO (Cell Individual Offset: specific cell offset of neighboring cells), and other information.

[0069] S402, The terminal to be cut off determination device establishes a terminal cut-off prediction model based on the network parameters of multiple second terminals when accessing the target base station and the network parameters when cutting off the target base station.

[0070] In one possible implementation, the aforementioned network parameters can be used as the input features X of the model, and the state of the terminal transmitting data with the target base station can be used as the input label Y of the model. The algorithm can be trained through a preset algorithm model to establish a terminal prediction model.

[0071] For example, the preset algorithms include at least one of the following: XGBoost algorithm, LightGBM algorithm, and CatBoost algorithm.

[0072] S403. The device for determining the terminal to be cut off inputs the current network parameters of multiple first terminals into the prediction model to determine the cut-off probability of each first terminal among the multiple first terminals.

[0073] For example, the device for determining the terminal to be cut off obtains the current RSRP, SINR, and CIO input prediction model of any one of the multiple first terminals through the network management system, and determines the cut-off probability of the first terminal.

[0074] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The device for determining the terminal to be handed over determines the network parameters of multiple second terminals when accessing the target base station, and the network parameters of multiple second terminals when handing over to the target base station. That is, it determines the network parameter data of the terminal when accessing the base station and the network parameter data when handing over to the base station in historical data; the device for determining the terminal to be handed over establishes a terminal handover prediction model based on the network parameters of multiple second terminals when accessing the target base station and the network parameters when handing over to the target base station. That is, the device for determining the terminal to be handed over trains the model based on the state of the second terminal transmitting data with the base station and the network parameters of the second terminal transmitting data with the base station in historical data, and constructs a prediction model; it inputs the current network parameters into the prediction model, thereby predicting the current handover probability of the first terminal; that is, it determines the handover impact parameters of each of the multiple first terminals accessing the target base station when the handover impact parameters include the handover probability.

[0075] One possible way to achieve this is by combining Figure 4 ,like Figure 5 As shown, the process of determining the network parameters of multiple second terminals when accessing the target base station and the network parameters of multiple second terminals when cutting out of the target base station, as described in S401, can be specifically implemented through the following S501-S504, which will be explained in detail below.

[0076] S501, The device for determining the terminal to be switched out acquires the transmission data between the target base station and the second terminal within a preset time period.

[0077] The preset time period is the period of data transmitted up to the current time.

[0078] In one possible implementation, the transmitted data includes at least one of the following: terminal identifier, timestamp, and network parameters corresponding to the timestamp.

[0079] For example, as shown in Table 1, Table 1 shows the transmission data of the second terminal when accessing / switching out of the target base station.

[0080] Table 1. Transmission data of the second terminal when accessing / switching out of the target base station.

[0081]

[0082]

[0083] S502, the terminal to be cut off determination device determines the timestamps of multiple second terminals accessing the target base station and the timestamps of multiple second terminals cutting off from the target base station based on the timestamps of the transmitted data.

[0084] It is understandable that the transmission data of the multiple second terminals obtained by the terminal to be switched out device includes: transmission data when the second terminal accesses the target base station and transmission data when the second terminal switches out of the target base station. Based on the timestamp of the transmission data, it can be determined that the transmission data is the transmission data when the second terminal accesses the target base station or the transmission data when the second terminal switches out of the target base station.

[0085] S503, The device for determining the terminal to be cut off determines the network parameters corresponding to the timestamps of the access to the target base station of the multiple second terminals as the network parameters of the multiple second terminals when accessing the target base station.

[0086] It is understandable that the transmission data of multiple second terminals obtained by the terminal to be cut off device includes: transmission data when the second terminal accesses the target base station and transmission data when the second terminal cuts off from the target base station. Based on the timestamp of the transmission data, it can be determined that the transmission data is the transmission data when the second terminal accesses the target base station, thereby determining the network parameters of multiple second terminals when accessing the target base station.

[0087] S504. The device for determining the terminal to be handed over determines the network parameters corresponding to the timestamps of the multiple second terminals handing over to the target base station as the network parameters of the multiple second terminals when handing over to the target base station.

[0088] It is understandable that the transmission data of multiple second terminals obtained by the terminal to be switched out device includes: transmission data when the second terminal accesses the target base station and transmission data when the second terminal switches out of the target base station. Based on the timestamp of the transmission data, it can be determined that the transmission data is the transmission data when the second terminal switches out of the target base station, thereby determining the network parameters of multiple second terminals when switching out of the target base station.

[0089] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The device for determining the terminal to be handed over first acquires the transmission data between the target base station and the second terminal within a preset time period; that is, it acquires the historical transmission data between the terminal and the target base station, and determines the timestamps of multiple second terminals accessing the target base station and the timestamps of multiple second terminals handing over to the target base station based on the timestamps in the historical transmission data. Based on the correspondence between the timestamps of multiple second terminals accessing the target base station and the network parameters of multiple second terminals when accessing the target base station, and the correspondence between the timestamps of multiple second terminals handing over to the target base station and the network parameters of multiple second terminals when handing over to the target base station, the device determines the network parameters of multiple second terminals when accessing the target base station and the network parameters of multiple second terminals when handing over to the target base station.

[0090] One possible way to achieve this is by combining Figure 5 ,like Figure 6As shown, the process of determining the timestamps of multiple second terminals accessing the target base station and the timestamps of multiple second terminals cutting out of the target base station based on the timestamps of the transmitted data in S502 can be specifically implemented through the following S601-S603, which will be described in detail below.

[0091] S601, The terminal to be switched out determination device determines the first timestamp of the first transmission data and the second timestamp of the second transmission data of the target second terminal within a preset time period.

[0092] Wherein, the first transmission data is any transmission data between the target base station and the target second terminal within a preset time period; the second transmission data is the transmission data that precedes the first transmission data and is adjacent to the first transmission data; and the target second terminal is any one of a plurality of second terminals.

[0093] S602. If the difference between the first timestamp and the second timestamp is not greater than a preset difference, the terminal to be switched out determination device determines the second timestamp as the timestamp when the target second terminal accesses the target base station.

[0094] The preset difference value is the time interval between the second terminal and the target base station for data transmission.

[0095] For example, the time interval for data transmission between the second terminal and the target base station is 2 seconds. When the difference between the first timestamp and the second timestamp is not greater than the preset difference of 2 seconds, it indicates that the second terminal and the target base station are transmitting data normally during the time period between the first timestamp and the second timestamp. At this time, the second timestamp can be determined as the timestamp when the target second terminal accesses the target base station.

[0096] S603. If the difference between the first timestamp and the second timestamp is greater than a preset difference, then the second timestamp is determined to be the timestamp when the target second terminal hands out of the target base station.

[0097] For example, the time interval for data transmission between the target second terminal and the target base station is 2 seconds. When the difference between the first timestamp and the second timestamp is greater than the preset difference of 2 seconds, it indicates that the target second terminal and the target base station did not transmit data normally during the time period between the first timestamp and the second timestamp. At this time, the second timestamp can be determined as the timestamp when the target second terminal switches out of the target base station.

[0098] For example, as shown in Table 1 above, the time interval for data transmission between the terminal and the target base station is 2 seconds. The difference between the timestamp of serial number 9 (12:01:36) and the timestamp of serial number 10 (12:01:40) is 4 seconds, which is greater than the preset time interval for data transmission. Therefore, it is determined that the terminal will switch out of the base station at 12:01:36.

[0099] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the terminal to be cut off determination device determines the first timestamp of the first transmission data and the second timestamp of the second transmission data of the target second terminal within a preset time period, and determines the second timestamp as the timestamp of the target second terminal cutting off from the target base station based on the difference between the first timestamp and the second timestamp being greater than a preset difference; or determines the second timestamp as the timestamp of the target second terminal accessing the target base station based on the difference between the first timestamp and the second timestamp not being greater than a preset difference.

[0100] One possible way to achieve this is by combining Figure 3 ,like Figure 7 As shown, when the handover impact parameters include dependent weights, the process of determining the handover impact parameters of each of the multiple first terminals accessing the target base station in the above-mentioned S301 and the handover terminal determination device can be specifically implemented through the following S701-S703, which will be explained in detail below.

[0101] S701, The terminal to be switched out determination device determines the current usage status of multiple network services of the target first terminal.

[0102] The target first terminal is any one of a plurality of first terminals.

[0103] In one possible implementation, network services include: voice services and internet access services.

[0104] For example, the device for determining the terminal to be switched out determines the current voice call status and data rate of each first terminal.

[0105] S702, The terminal to be switched out determination device determines the weight of each network service based on the usage of each network service.

[0106] In one possible implementation, when the first terminal is in a voice call state, the voice service weight is 1, and when the voice call state is not in a voice call state, the voice service weight is 0.

[0107] In one possible implementation, the user's internet access weight W 上网 Satisfy the following formula 1:

[0108] W 上网 =C 上网速率 / 1024 Formula 1

[0109] Among them, C 上网速率 This represents the current data rate of the terminal, in KB / s.

[0110] For example, if the current data rate used by the terminal is 512KB / s, then the corresponding internet access weight W is... 上网 =0.5.

[0111] S703. The terminal to be switched out determination device sums the weights of each network service of each first terminal to determine the dependency weight of the target first terminal.

[0112] For example, if the target first terminal is in a voice call state, the voice service weight value is 1, the current data rate used by the terminal is 512KB / s, and the internet access weight value is 0.5, then the dependency weight of the target first terminal is determined to be 1.5.

[0113] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the terminal to be cut off determination device determines the current usage of multiple network services of the target first terminal and determines the weight of the multiple network services of the target first terminal. Based on the weight of the multiple network services of the target first terminal, the dependency weight of each first terminal among the multiple first terminals is determined, that is, the cut-off impact parameter of each first terminal among the multiple target first terminals accessing the target base station is determined when the cut-off impact parameter includes the dependency weight.

[0114] In one possible implementation, when the influencing parameters include the cut-out probability, the preset condition includes: the cut-out probability of the first terminal is greater than a first threshold.

[0115] Understandably, when the influencing parameters include the handover probability, if the handover probability of the first terminal is greater than the first threshold, then the probability of the first terminal handing over to the target base station is relatively high. It can be determined that the first terminal is the terminal to be handed over with less impact on the network experience after handing over to the target base station.

[0116] When the influencing parameters include dependency weights, the preset conditions include: the dependency weight of the first terminal is less than the second threshold.

[0117] Understandably, when the influencing parameters include dependency weights, if the dependency weight of the first terminal is less than the second threshold, then the impact of the first terminal's service on the first terminal after it leaves the target base station is relatively small. It can be determined that the first terminal is the terminal to be handed over, and the network experience of the terminal will be less affected after it leaves the target base station.

[0118] When the influencing parameters include the cut-out probability and the dependency weight, the preset conditions include: the cut-out probability of the first terminal is greater than the first threshold and the dependency weight of the first terminal is less than the second threshold.

[0119] Understandably, when the influencing parameters include the handover probability and the dependency weight, if the handover probability of the first terminal is greater than the first threshold, then the probability of the first terminal handing over to the target base station is relatively high; if the dependency weight of the first terminal is less than the second threshold, then the impact on the first terminal's service after handing over to the target base station is relatively small, and it can be determined that the first terminal is the terminal to be handed over whose network experience will be less affected after handing over to the target base station.

[0120] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The terminal to be handed over determination device first determines the handover impact parameters of each of the multiple first terminals accessing the target base station; the handover impact parameters include at least one of the following: handover probability and dependency weight; wherein, the handover probability is used to characterize the probability that the first terminal is currently handing over from the target base station; the dependency weight is used to characterize the degree of impact on the first terminal's service when the first terminal hands over from the target base station; that is, it determines the possibility that the multiple first terminals accessing the target base station actively hand over from the target base station and the degree of impact on the first terminal's service when handing over from the target base station. Furthermore, based on the handover impact parameters, the first terminal among the multiple first terminals whose handover impact parameters meet preset conditions is determined as the terminal to be handed over. That is, the first terminal whose impact on the user's network experience is small after handing over from the base station is determined as the handover terminal; the base station actively hands over the terminal whose impact on the network experience is small after handing over from the base station, thereby reducing the pressure on the base station, avoiding the user's network connection being disconnected due to processing performed on the base station side, and thus ensuring the user's network experience.
