[0003] However, when a high-load base station carries the Industrial Ethernet protocol, the target neighboring base stations determined based on load information for load balancing may not meet the data transmission requirements of the Industrial Ethernet protocol. Summary of the Invention

[0036] The following explanations of the terms used in the embodiments of this disclosure are provided to facilitate the reader's understanding.

[0037] 1. Industrial Ethernet

[0038] Industrial Ethernet is a local area network (LAN) built on Ethernet technology, used for data transmission and communication control in industrial environments. Essentially the same as standard Ethernet, it is based on Layer 1 and Layer 2 protocols of the Open Systems Interconnection Reference Model (OSI), transmitting data through the physical and data link layers.

[0039] The essence of Industrial Ethernet lies in its real-time performance, reliability, and security required for industrial applications. To meet the high real-time demands of industrial environments, Industrial Ethernet introduces precise timing mechanisms and uses more stable hardware transmission media. Simultaneously, it employs various error correction and fault-tolerance mechanisms during data transmission to ensure data integrity and reliability.

[0040] Currently, in scenarios involving load balancing of high-load base stations, a common load balancing method is to transmit load information of neighboring base stations through the network interface between NG-RAN nodes, determine the target neighboring base station for load balancing based on the load information of neighboring base stations, and switch the terminals accessing the high-load base station to the target neighboring base station, thereby reducing the load on the high-load base station.

[0041] However, when a high-load base station carries the Industrial Ethernet protocol, the neighboring base stations that are load-balanced based on load information may not be able to meet the data transmission requirements of the Industrial Ethernet protocol.

[0042] To address the aforementioned technical problems, this disclosure provides a base station load balancing method, apparatus, and storage medium. This addresses the issue that, when a high-load base station carries an Industrial Ethernet protocol, neighboring base stations determined based on load information for load balancing may not meet the data transmission requirements of the Industrial Ethernet protocol. The method includes: acquiring Industrial Ethernet data from the high-load base station and neighboring base stations; the neighboring base stations are non-high-load base stations adjacent to the high-load base station; the Industrial Ethernet data includes: Industrial Ethernet protocol priority and Industrial Ethernet indicator data; the Industrial Ethernet indicator data characterizes the Industrial Ethernet data transmission capability of the base station; and identifying a first target base station among the neighboring base stations whose Industrial Ethernet protocol priority is lower than that of the high-load base station; identifying a second target base station whose Industrial Ethernet indicator data in the first target base station meets a first preset condition; and determining the second target base station as the load balancing base station of the high-load base station, i.e., identifying the Industrial Ethernet protocol priority carried by the high-load base station among multiple neighboring base stations. The first target base station, which has a lower priority than the high-load base station in terms of the Industrial Ethernet protocol, ensures that terminals switched out from the high-load base station have priority in transmitting Industrial Ethernet data. Based on the Industrial Ethernet indicator data of the first target base station, a second target base station is determined. The second target base station is used to access terminals switched out from the high-load base station. That is, based on the more important data indicators in the Industrial Ethernet network, the second target base station for accessing terminals switched out from the high-load base station is determined, thereby meeting the data transmission requirements of the Industrial Ethernet protocol. This solves the technical problem in the prior art where adjacent base stations determined based on load information for load balancing may not meet the data transmission requirements of the Industrial Ethernet protocol.

[0043] In one possible implementation, the aforementioned base station load balancing method can be applied to the base station load balancing system 100. The following, in conjunction with... Figure 1 This application provides a detailed description of a base station load balancing system 100 according to an embodiment. For example... Figure 1 As shown, Figure 1 A base station load balancing system 100 is provided for embodiments of this disclosure. The system includes: a high-load base station 101, a base station load balancing device 102, and adjacent base stations 103.

[0044] Among them, high-load base station 101 is a base station whose number of access terminals exceeds a preset threshold, and adjacent base station 103 is a non-high-load base station adjacent to high-load base station 101; base station load balancing device 102 is used to acquire first industrial Ethernet data of high-load base station 101 and second industrial Ethernet data of multiple adjacent base stations 103; industrial Ethernet data includes: industrial Ethernet protocol priority and industrial Ethernet indicator data; the industrial Ethernet indicator data is used to characterize the industrial Ethernet data transmission capability of the base station; and based on the first industrial Ethernet protocol priority of high-load base station 101 and the second industrial Ethernet protocol type of multiple adjacent base stations 103, a first target base station among multiple adjacent base stations is determined; the first target base station is an adjacent base station among multiple adjacent base stations 103 whose industrial Ethernet protocol priority is lower than that of high-load base station; based on the industrial Ethernet indicator data of the first target base station, a second target base station among the first target base stations is determined; the second target base station is used to access terminals cut off from high-load base station 101.

[0045] In one possible implementation, the hardware structure of the base station load balancing device 102 in the aforementioned base station load balancing system 100 includes: Figure 2 The components included in the base station load balancing device 200 shown below are described in detail below. Figure 2 The hardware structure of the base station load balancing device 102 is described using the base station load balancing device 200 shown as an example. Figure 2 As shown, the base station load balancing 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.

[0046] 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).

[0047] Communication line 202 may include a path for transmitting information between the aforementioned components.

[0048] 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.

[0049] 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.

[0050] 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 base station load balancing 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.

[0051] As one possible implementation, processor 201 may include one or more CPUs, for example Figure 2 CPU0 and CPU1 in the example. Alternatively, the base station load balancing device 200 may include multiple processors, such as CPU0 and CPU1. Figure 2 The processors 201 and 207 are included. Alternatively, the base station load balancing device 200 may also include an output device 205 and an input device 206.

[0052] The base station load balancing method provided in the embodiments of this disclosure will be described in detail below.

[0053] like Figure 3 As shown, Figure 3 The base station load balancing method provided in this disclosure can be applied to, for example... Figure 2 The base station load balancing device shown includes the following methods S301-S304, which will be described in detail below.

[0054] S301, The base station load balancing device acquires industrial Ethernet data from high-load base stations and adjacent base stations.

[0055] Among them, a high-load base station is a base station with more than a preset threshold number of access terminals; an adjacent base station is a non-high-load base station that is adjacent to a high-load base station.

[0056] In one possible implementation, the industrial Ethernet data includes: industrial Ethernet protocol priority and industrial Ethernet indicator data; the industrial Ethernet indicator data is used to characterize the industrial Ethernet data transmission capability of the base station.

[0057] In one possible implementation, the commonly used Xn interface interaction information is shown in Table 1. The base station load balancing device adds industrial Ethernet index data to the Xn interface interaction information. The Xn interface interaction information after adding industrial Ethernet index data is shown in Table 2. The base station load balancing device interacts with information through the Xn interface to obtain the first industrial Ethernet data of the high-load base station and the second industrial Ethernet data of multiple adjacent base stations.

[0058] Table 1 Xn Interface Interaction Information

[0059] >>Radio Resource Status O >>TNL Capacity Indicator O >>Composite Available Capacity Group O >>Slice Available Capacity O >>Number of Active UEs O >>RRC Connections O

[0060] Table 2 shows the Xn interface interaction information after adding industrial Ethernet index data.

[0062] S302, The base station load balancing device determines the first target base station among adjacent base stations whose Industrial Ethernet Protocol (IEP) priority is lower than that of the high-load base station.

[0063] Among them, the first target base station is the neighboring base station with the Industrial Ethernet Protocol (IEP) priority lower than that of the high-load base station among multiple adjacent base stations.

[0064] In one possible implementation, industrial Ethernet protocols can be divided into three categories. The first category is entirely based on TCP / UDP / IP, with no hardware changes, and uses traditional Ethernet control. The second category is partially based on TCP / UDP / IP, with no hardware changes, and includes the process data protocol, directly transmitted via Ethernet. TCP / UDP still exists and is controlled by the timing layer. The third category involves hardware changes and uses a real-time Ethernet controller. These three types of industrial Ethernet protocols have different requirements for the real-time performance of data transmission. The third category has the highest real-time requirement, followed by the second category, and the lowest. The base station load balancing device determines the industrial Ethernet protocol priority of adjacent base stations that are lower than the industrial Ethernet protocol priority of the high-load base station based on the first industrial Ethernet protocol type of the high-load base station and the second industrial Ethernet protocol types of multiple adjacent base stations.

[0065] Understandably, in order to ensure the industrial Ethernet data transmission needs of the terminals switched out from high-load base stations, the industrial Ethernet protocol priority of the base station accessed by the terminals switched out from high-load base stations must be lower than that of the high-load base station.

[0066] S303, The base station load balancing device determines the second target base station whose industrial Ethernet index data in the first target base station meets the first preset condition.

[0067] The second target base station is used to access terminals switched out by high-load base stations.

[0068] In one possible implementation, the base station load balancing device determines a second target base station among the first target base stations that meets the data transmission requirements of the industrial Ethernet protocol, based on the industrial Ethernet index data of the first target base station.

[0069] S304. The base station load balancing device determines the second target base station as the load balancing base station of the high-load base station.

[0070] In one possible implementation, the base station load balancing device sends an instruction to the second target base station, instructing the second target base station to act as the load balancing base station for the high-load base station.

[0071] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The base station load balancing device first acquires industrial Ethernet data from a high-load base station and adjacent base stations; the adjacent base stations are non-high-load base stations adjacent to the high-load base station; the industrial Ethernet data includes: industrial Ethernet protocol priority and industrial Ethernet indicator data; the industrial Ethernet indicator data is used to characterize the industrial Ethernet data transmission capability of the base station; and a first target base station with an industrial Ethernet protocol priority lower than that of the high-load base station among the adjacent base stations is determined; a second target base station whose industrial Ethernet indicator data in the first target base station meets the first preset condition is determined; the second target base station is determined to be the load balancing base station of the high-load base station, that is, multiple adjacent base stations are determined. The first target base station, whose own Industrial Ethernet protocol priority is lower than that of the high-load base station, ensures that the terminals cut out from the high-load base station have priority for Industrial Ethernet data transmission. Based on the Industrial Ethernet indicator data of the first target base station, a second target base station is determined. The second target base station is used to access the terminals cut out from the high-load base station. That is, based on the more important data indicators in the Industrial Ethernet network, the second target base station for accessing the terminals cut out from the high-load base station is determined, thereby meeting the data transmission requirements of the Industrial Ethernet protocol. This solves the technical problem in the prior art that adjacent base stations determined based on load information for load balancing may not meet the data transmission requirements of the Industrial Ethernet protocol.

[0072] In one possible implementation, the industrial Ethernet indicator data includes multiple sub-indicator data, and the first preset condition includes multiple sub-conditions with different priorities; the sub-indicator data corresponds one-to-one with the sub-conditions. For example... Figure 4 As shown in the above S303, the process by which the base station load balancing device determines the second target base station whose industrial Ethernet index data in the first target base station meets the first preset condition can be specifically implemented through the following S401-S403, which will be explained in detail below.

[0073] S401, Step 1. The base station load balancing device determines the third target base station among the first target base stations whose target sub-indicator data meets the target sub-condition.

[0074] In one possible implementation, the base station load balancing device interacts with the Xn interface to obtain the target sub-indicator data of the first target base station and determines the third target base station whose target sub-indicator data satisfies the target sub-condition.

[0075] S402, Step 2. When the number of third target base stations is equal to a preset value, the base station load balancing device determines the third target base station as the second target base station.

[0076] In one possible implementation, when the base station load balancing device determines that the first target base station contains a third target base station that satisfies the target sub-condition, the third target base station is determined to be the second target base station.

[0077] S403, Step 3. When the number of third target base stations is greater than the preset value, the base station load balancing device updates the target sub-conditions and re-executes steps 1, 2 and 3 until the number of third target base stations is equal to the preset value, and determines the third target base station as the second target base station.

[0078] In one possible implementation, when the base station load balancing device determines that the first target base station includes multiple third target base stations that meet the target sub-conditions, it updates the target sub-conditions and repeats the steps S401-S402 above until the first target base station includes one third target base station that meets the target sub-conditions, at which point the third target base station is determined to be the second target base station.

[0079] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The base station load balancing device determines the third target base station among the first target base stations whose target sub-index data meets the target sub-conditions, that is, it determines the third target base station that meets the Ethernet network transmission requirements based on the target sub-conditions; when the number of third target base stations is equal to a preset value, the third target base station is determined as the second target base station; and when the number of third target base stations is greater than the preset value, the target sub-conditions are updated, and steps 1, 2, and 3 are re-executed until the number of third target base stations is equal to the preset value, and the third target base station is determined as the second target base station; thereby, a third target base station that meets the Ethernet network transmission requirements is determined based on the priority of the sub-target conditions, and load balancing is performed between it and the high-load base station.

[0080] In one possible implementation, the sub-indicator data includes at least one of the following: time synchronization accuracy, data transmission duration, reliability, Ethernet real-time data throughput, number of end nodes, Ethernet non-real-time data bandwidth ratio, redundancy recovery time, and basic network topology type.

[0081] The sub-conditions include at least one of the following: highest time synchronization accuracy, shortest data transmission time, highest reliability, lowest Ethernet real-time data throughput, fewest number of end nodes, highest proportion of Ethernet non-real-time data bandwidth, shortest network redundancy recovery time, and the basic network topology type is star topology.

[0082] In one possible implementation, combining Figure 4 like Figure 5As shown in the above S303, the process by which the base station load balancing device determines the second target base station whose industrial Ethernet index data in the first target base station meets the first preset conditions also includes the following S501-S502, which will be described in detail below.

[0083] S501, The base station load balancing device determines the fourth target base station among multiple adjacent base stations that meets the second preset condition.

[0084] In one possible implementation, the second preset condition includes at least one of the following: the time synchronization accuracy of adjacent base stations is greater than the first preset threshold, the data transmission duration of adjacent base stations is less than the second preset threshold, and the data transmission success rate of adjacent base stations is higher than the third preset threshold.

[0085] In one possible implementation, the base station load balancing device obtains the time synchronization accuracy, data transmission duration, and data transmission success rate of each adjacent base station through the Xn interface.

[0086] S502, The base station load balancing device determines the base station that meets the first preset condition among the base stations other than the fourth target base station in the first target base station as the second target base station.

[0087] Understandably, when the base station load balancing device determines that the adjacent base stations meet the second preset conditions, it determines that the industrial Ethernet network of the fourth target base station is in a high-security state. In order to ensure the industrial Ethernet data transmission service of the fourth target base station, the fourth target base station cannot be used as the second target cell for load balancing at this time.

[0088] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the base station load balancing device determines the fourth target base station among the first target base stations that meets the second preset conditions, thereby avoiding using the fourth target base station, which is in a high-security state for industrial Ethernet services, as the base station for load balancing.

[0089] In one possible implementation, combining Figure 3 like Figure 6 As shown in the above S302, the process by which the base station load balancing device determines the first target base station whose Industrial Ethernet Protocol (IEP) priority is lower than that of the high-load base station among the adjacent base stations can be specifically implemented through the following S601-S603, which will be explained in detail below.

[0090] S601. When the industrial Ethernet protocol type of a high-load base station is of type 1, the base station load balancing device determines the adjacent base station of the adjacent base station whose industrial Ethernet protocol type is of type 1 as the first target base station.

[0091] In one possible implementation, the industrial Ethernet protocol types include: a first type, a second type, and a third type; wherein, the first type is an industrial Ethernet protocol for data transmission via a traditional Ethernet controller.

[0092] Examples of first-type industrial Ethernet protocols include: PROFINET, ETHERNET / IP, MODBUS TCP, etc.

[0093] It is understandable that, when the first industrial Ethernet protocol type is the first type, the base station load balancing device will use the adjacent base station with the first type of industrial Ethernet protocol as the first target base station in order to ensure the industrial Ethernet network services of the switched-out terminal, since the second and third types of industrial Ethernet protocols have higher priority.

[0094] S602. When the industrial Ethernet protocol type of a high-load base station is type 2, the base station load balancing device determines the adjacent base stations with industrial Ethernet protocol types of type 1 and type 2 as the first target base station.

[0095] The second type is the industrial Ethernet protocol that transmits data directly through Ethernet frames.

[0096] Examples of second-type industrial Ethernet protocols include PROFINET RT, POWERLINK, etc.

[0097] It is understandable that, when the first industrial Ethernet protocol type is the second type, the base station load balancing device will use the third type of industrial Ethernet protocol as the first target base station in order to ensure the industrial Ethernet network services of the cut-out terminal.

[0098] S603. When the industrial Ethernet protocol type of a high-load base station is the third type, the base station load balancing device determines the adjacent base stations with industrial Ethernet protocol types of the first, second, and third types as the first target base station.

[0099] The third type is the industrial Ethernet protocol that transmits data through a real-time Ethernet controller.

[0100] Examples of second-type industrial Ethernet protocols include: PROFINET IRT, CC-LINK IE, SERCOSIII, ETHERCAT, etc.

[0101] It is understandable that when the first industrial Ethernet protocol type is the third type, the third type of industrial Ethernet protocol has a higher priority. Among the adjacent base stations, the adjacent base stations with industrial Ethernet protocol types of the first, second and third types are all the first target base stations.

[0102] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the base station load balancing device determines the priority of the industrial Ethernet protocol among adjacent base stations, and the adjacent base station with the lower priority of the industrial Ethernet protocol than the high-load base station is the first target base station, thus ensuring the data transmission needs of the industrial Ethernet network services of the terminal switched out by the high-load base station.
