Green energy-based load transfer method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on October 30, 2023, with application number 202311434392.8 and application name “Method and device for load transfer based on green energy”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a method and device for load transfer based on green energy. Background Art

[0003] Currently, in terms of network construction and maintenance, energy conservation and carbon reduction of equipment, sites and computer rooms is one of the key research directions in the communications field.

[0004] Existing technologies typically improve carbon emission efficiency by adjusting the green energy allocation or scheduling strategy of the site energy management system, for example, by increasing the proportion of green energy supply. However, the green energy allocation or scheduling capabilities of the site energy management system are limited. For example, the solar energy captured by the photovoltaic panels on a base station can only be used by that base station. Even if the base station fully utilizes solar energy during energy consumption, when the lighting conditions are favorable, the solar energy supply may exceed the base station's energy consumption, resulting in insufficient solar energy utilization and, in turn, preventing further improvements in carbon emission efficiency.

[0005] Therefore, how to further improve the carbon emission efficiency of communication equipment is a hot topic of current research.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide a method and apparatus for load transfer based on green energy, so as to further improve the carbon emission efficiency of communication equipment.

[0008] To achieve the above objectives, this application adopts the following technical solutions:

[0009] In a first aspect, a load transfer method is provided. The method is applied to a first management function and includes: obtaining a value of at least one green energy indicator of a first network element, where the green energy indicator indicates green energy usage. If indication information is sent, the indication information is used to instruct the first network element to perform green energy-based load transfer between network elements based on the value of the at least one green energy indicator.

[0010] Based on the method described in the first aspect, it can be seen that the value of at least one green energy indicator of the first network element is obtained through the first management function, the green energy usage of the first network element is analyzed based on the green energy indicator, and instruction information is sent. The instruction information is used to instruct the first network element to perform green energy-based load transfer between network elements based on the value of the at least one green energy indicator. In this way, the utilization rate of green energy can be improved when green energy cannot be flexibly allocated across communication devices, thereby improving the carbon emission efficiency of communication devices.

[0011] In one possible design, the method of the first aspect may further include: before sending the indication information, determining whether a value of a first green energy indicator among at least one green energy indicator is outside a threshold range. In other words, if the value of the first green energy indicator among the at least one green energy indicator is outside the threshold range, it indicates that the value of the first green energy indicator is low or high, and only then is it necessary to send the indication information to trigger the green energy-based load transfer.

[0012] In one possible design scheme, the indication information is used to indicate the first load amount that needs to be transferred between the first network element and the second network element based on the green energy indicator. The indication information may include at least one of the following: the identifier of the first network element, the identifier of the second network element, and the first load amount, and the second network element is a network element of the same functional type as the first network element. The first management function is used to instruct the first network element and the second network element of the same functional type to perform load transfer based on green energy, and to instruct the transfer of the first load amount between the first network element and the second network element. The first management function can determine the transfer amount between the first network element, the second network element, and the first network element and the second network element by itself, rather than by the first network element itself, thereby reducing the overhead on the device side.

[0013] Optionally, at least one green energy indicator may include at least one of the following: carbon emission efficiency, green energy supply, energy consumption, green energy usage, green energy power, the proportion of green energy consumption in energy consumption, remaining available green energy, carbon emissions and carbon intensity. The above green energy indicators can be used to accurately analyze the use of green energy. Of course, the corresponding indicators can be selected according to the specific situation, and there is no restriction on this.

[0014] In a possible design scheme, the method described in the first aspect may further include: before sending the indication information to the first network element, obtaining the energy usage of each of the multiple network elements related to the first network element. Based on the energy usage of each of the multiple network elements, determining a second network element from the multiple network elements that can transfer the load with the first network element. It can be understood that the multiple network elements related to the first network element can be network elements of the same functional type as the first network element, network elements with a close physical distance and / or network elements with overlapping signal coverage. In this way, the second network elements selected can interact with the first network element and can more conveniently achieve load transfer based on green energy with the first network element.

[0015] The energy usage of the plurality of network elements includes: the value of the green energy index of the plurality of network elements, and the difference between the maximum or minimum value in the threshold range of the respective green energy index. The load transfer between the second network element and the first network element is as follows: the difference between the value of the green energy index of the first network element and the minimum value in the threshold range of the green energy index matches the difference between the value of the green energy index of the second network element and the maximum value in the threshold range of the green energy index; or the difference between the value of the green energy index of the first network element and the maximum value in the threshold range of the green energy index matches the difference between the value of the green energy index of the second network element and the minimum value in the threshold range of the green energy index.

[0016] In one possible design, the indication information is used to instruct a load balancing optimization function to perform green energy-based load balancing between network elements, where the load balancing optimization function is deployed in a first network element. The indication information includes at least one of the following: an identifier of the load balancing optimization function and green energy reference indication information, where the green energy reference indication information is used to indicate whether to perform green energy-based load balancing between network elements based on a green energy indicator.

[0017] It is understandable that the first management function directly sends an indicative configuration policy to the first network element, without specifying the destination for load transfer. Instead, the load balancing optimization function makes its own judgment. This allows the first network element to determine whether to consider green energy indicators when making load balancing adjustments based on its actual situation. This allows for more dynamic and flexible load balancing based on green energy indicators. Furthermore, the load balancing optimization function defines a new attribute value, reusing existing signaling elements for implementation, making it more friendly to existing standards and easier to implement.

[0018] In another possible design, the indication information is used to instruct a green energy balancing function to perform load transfer based on green energy between network elements, where the green energy balancing function is deployed in a first network element. The indication information includes at least one of the following: an identifier of the green energy balancing function and green energy reference indication information. The green energy balancing function is used to manage the balance between green energy supply and energy consumption. The green energy reference indication information is used to indicate whether to perform load balancing or load transfer based on green energy between network elements based on a green energy indicator.

[0019] As can be understood, the green energy balancing function can be used to optimize the balance between green energy supply and network element energy consumption. The first management function directly sends an indicative configuration policy to the first network element, without specifying the load transfer destination. Instead, the green energy balancing function makes its own judgment, allowing the first network element to make decisions based on its own actual conditions. This allows for more dynamic and flexible load transfer based on green energy indicators. Furthermore, the green energy balancing function is implemented by a newly defined signaling element, decoupling it from existing solutions and providing greater flexibility.

[0020] Optionally, the indication information may further include a threshold range for at least one green energy indicator. The threshold range for the green energy indicator is used to define a standard value for green energy measurement or statistics. The threshold range does not require determination by the first network element; it can simply be configured for the first network element. Of course, the threshold range can also be preconfigured or predefined by a protocol locally in the first network element, eliminating the need for indication, thereby reducing communication overhead.

[0021] Optionally, sending the indication information may include: sending the indication information to a second management function related to the first network element. The second management function may be a configuration management function, which may be used to forward the indication information to the first network element, or configure parameters of a load balancing optimization function or a green energy balancing function based on the indication information. When the first management function cannot communicate directly with the first network element, the first management function may indirectly provide an indication or configuration to the first network element through the second management function.

[0022] In another possible design, the first management function includes a network autonomous management function and a near real-time wireless intelligent controller module, that is, the existing modules are reused for implementation, which is more friendly to the support of existing standards and less difficult to implement.

[0023] Optionally, when the first management function is a near-real-time wireless intelligent controller module, the first network element includes a first base station; obtaining the value of at least one green energy indicator of the first network element includes obtaining a traffic indicator of a terminal device connected to the first base station. Determining the value of at least one green energy indicator generated by the terminal device based on the traffic indicator of the terminal device. By monitoring the traffic indicators of the terminal devices served by the first base station, the terminal device-level green energy indicator of the first base station is calculated, thereby enabling more precise determination of traffic diversion strategies.

[0024] The indication information is used to indicate the terminal devices that need to be migrated between the first base station and the second base station based on green energy. The indication information includes the identifier of the first base station, the identifier of the second base station, and the identifier of the terminal devices connected to the first base station that need to be migrated. By migrating the number of terminal devices connected to the first base station based on green energy, traffic between multiple base stations can be intelligently controlled, thereby improving the user experience.

[0025] In a second aspect, a method for green energy-based load transfer is provided. The method is applied to a third management function and includes obtaining a threshold range of a green energy indicator. A green energy balancing service request is sent to the first management function. The green energy balancing service request includes at least one of the following: an identifier of a first network element and the threshold range of the green energy indicator.

[0026] Based on the method described in the second aspect, it can be seen that the third management function can be a green energy management function and a non-real-time wireless intelligent controller module, which requests green energy balancing service from the first management function through the third management function, and carries the identifier of the first network element and the threshold range of the green energy indicator. Then, the first management function ensures the green energy indicator through load transfer based on green energy.

[0027] In a third aspect, a method for green energy-based load transfer is provided. The method is applied to a fourth management function, and includes: receiving a measurement request for a green energy indicator value of a first network element from a first management function; and sending the green energy indicator value of the first network element to the first management function based on the measurement request.

[0028] Based on the method described in the third aspect, it can be known that the fourth management function can be a performance management function, which receives the measurement request for the value of the green energy indicator of the first network element sent by the first management function, and measures the green energy indicator of the first network element based on the measurement request, and sends the value of the green energy indicator of the first network element to the first management function, so that the first management function determines the indication information through the value of the green energy indicator of the first network element to realize load transfer based on green energy.

[0029] In a fourth aspect, a method for green energy-based load transfer is provided. The method is applied to a first network element and includes: receiving indication information, wherein a green energy indicator is used to indicate green energy usage, and the indication information is used to instruct the first network element to perform green energy-based load transfer between network elements; and performing green energy-based load transfer between network elements based on the indication information.

[0030] In one possible design scheme, the indication information is used to indicate a first load amount that needs to be transferred between the first network element and the second network element based on a green energy indicator.

[0031] Optionally, the indication information includes an identifier of the first network element, an identifier of the second network element, and the first load amount, and the second network element is a network element of the same functional type as the first network element.

[0032] Among them, at least one green energy indicator includes at least one of the following: carbon emission efficiency, green energy supply, energy consumption, green energy usage, green energy power, the proportion of green energy consumption in energy consumption, remaining available green energy, carbon emissions and carbon intensity.

[0033] Optionally, the second network element is a network element that can transfer the load of the first network element according to respective energy usage conditions of the plurality of network elements, and the plurality of network elements are network elements related to the first network element.

[0034] The energy usage of each of the multiple network elements includes: the value of the green energy index of each of the multiple network elements, and the difference between the maximum value or the minimum value within the threshold range of the respective green energy index. The load transfer between the second network element and the first network element is enabled if: the difference between the value of the green energy index of the first network element and the maximum value or the minimum value within the threshold range of the respective green energy index matches the difference between the value of the green energy index of the second network element and the maximum value or the minimum value within the threshold range of the respective green energy index.

[0035] In one possible design scheme, the indication information is used to instruct the load balancing optimization function to perform load balancing based on green energy between network elements. The load balancing optimization function is deployed in the first network element. The indication information includes at least one of the following: an identifier of the load balancing optimization function and green energy reference indication information. The green energy reference indication information is used to indicate whether to perform load balancing based on green energy between network elements based on green energy indicators.

[0036] Optionally, the indication information is used to instruct the green energy balancing function to perform load transfer based on green energy between network elements. The green energy balancing function is deployed in the first network element. The indication information includes at least one of the following: an identifier of the green energy balancing function and green energy reference indication information. The green energy balancing function is used to manage the balance between green energy supply and energy consumption. The green energy reference indication information is used to indicate whether to perform load transfer based on green energy between network elements based on green energy indicators.

[0037] Optionally, the indication information further includes a threshold range of at least one green energy indicator.

[0072] For ease of understanding, the technical terms involved in the embodiments of this application are first introduced below.

[0073] 1. Explanation of key terms:

[0074] Carbon footprint (CO2 footprint): refers to the collection of greenhouse gas emissions caused by corporate organizations, activities, products or individuals through transportation, food production and consumption, and various production processes.

[0075] Green energy (green energy): also known as clean energy, new energy and renewable energy, refers to energy that does not destroy or harm the environment and does not emit pollutants, such as solar power generation, wind power generation, etc.

[0076] Green energy index: A general term for indicators used to measure the green energy usage or carbon emissions related to energy consumption of electrical equipment in communication networks. Specific examples are as follows:

[0077] Proportion of green energy use: the proportion of green energy consumption in total energy consumption.

[0078] Green energy usage: that is, the consumption of green energy during the start and end time.

[0079] Green energy supply: The green energy supply calculated or estimated during the start and end time, which is determined by the lighting conditions during the start and end time.

[0080] Carbon emission: the amount of carbon emitted during the start and end time.

[0081] Carbon intensity: the equivalent amount of carbon dioxide emitted per unit of activity.

[0082] Carbon Emission Efficiency: Carbon emission efficiency.

[0083] 2. 3GPP Standard Background:

[0084] The current 3GPP energy conservation project addresses energy usage issues in communication networks from the perspective of energy efficiency measurement and energy conservation:

[0085] Define the measurement method for energy efficiency key performance indicators (EE KPIs) and calculate EE KPIs from the dimensions of end-to-end (E2E) network, subnet, network element, communication site, etc. Add energy efficiency parameters to the slice service profile to reflect customer requirements for slice energy efficiency.

[0086] Two states are defined for a cell, a network element (NE) or a network function (NF), i.e., a cell, a NE or a NF can be in one of the following two states regarding energy saving: a not Energy Saving state and an energy Saving state, which are used to indicate whether the cell is in an energy saving state.

[0087] Based on the above energy-saving status, a complete energy-saving solution can include the following two steps:

[0088] Energy saving activation: Change from non-energy saving state to energy saving state.

[0089] Energy saving deactivation: Change from energy saving state to non-energy saving state.

[0090] The energy-saving state is changed by operating the above two steps.

[0091] 3. Site Energy Management System:

[0092] The site energy management system focuses on the unified management of site energy, environmental, and safety components. By monitoring the performance and alarm information of relevant equipment in real time, it helps maintenance personnel remotely manage the site, conducts statistical analysis of site energy consumption, and provides data support and recommendations for energy-saving optimization. In scenarios where power is supplied by utility power, batteries, and renewable energy, the site energy management system manages energy systems such as solar panels, utility power, UPS, batteries, diesel generators, fuel tanks, and other power supply components. Solar panels are placed according to the planned location of the base station.

[0093] 4. Definition of carbon emission efficiency standards for the communications industry:

[0094] The carbon emissions of information and communications technology (ICT) sites apply to all ICT sites of all sizes, including internet technology (IT) rooms located in buildings. The carbon emissions of communications systems are defined as:

[0095] EC i : represents the annual energy consumption of the ICT site from the power source i (local, heating / cooling circuit, grid), in MWh;

[0096] CEF i : annual average carbon emission factor of power source i;

[0097] KPI CE : Expressed in tons of carbon dioxide equivalent.

[0098] Note:

[0099] Carbon emission efficiency: the ratio of CO2 equivalent to actual energy consumption of an ICT site in a year:

[0100] KPI CEE =KPI CE / KPI EC

[0101] 5. Calculation of carbon emission efficiency:

[0102] An example of a calculation formula for carbon emission efficiency in a communication network:

[0103] The carbon efficiency in the embodiments of the present application is different from the traditional definition of energy efficiency (effective output provided by unit energy consumption). For example, based on the carbon emissions of the network and the differences in the business focus of different scenarios, reasonable multi-dimensional indicators are selected for comprehensive evaluation to obtain carbon efficiency. This can drive the wireless network to continue to develop in the direction of providing more business volume and better business experience with a smaller carbon footprint. For example, carbon efficiency can satisfy formula (1):

[0104] Carbon efficiency = service level / carbon emissions (1)

[0105] The numerator is the service level, which is used to describe the utility of communication network services. Due to the increase in emerging business types in next-generation wireless networks, the service level can be a parameter related to the total amount of data transmission, user experience, and scenario-based business types. ri (scenario factor) is determined by the business type and business requirements of different scenarios: for example, Service = r_1*Data Volume + r_2*Qos + r_3*Coverage +... The denominator is carbon emissions (also called carbon footprint), that is, the carbon emissions generated by communication equipment due to electricity consumption.

[0106] For example, if Q is the carbon footprint, the carbon emission efficiency (CE) can satisfy formula (2):

[0107] η_CE=(λT×μ) / Q (2)

[0108] η_CE represents carbon efficiency. λT represents the transpose of the vector λ. λ = {λ1,λ2,.....λk} represents the weight vectors for K different application scenarios (e.g., ultra-high speed, ultra-large-scale access, high mobility and low latency, and ultra-low power communication). The specific value of λk is determined by the proportion of traffic in the Kth application scenario (e.g., the ratio of traffic in the Kth application scenario to overall traffic) and / or the importance of the Kth application scenario. K can be an integer greater than or equal to 1.

[0109] Vector μ = {μ1, μ2, .....μk} represents the utility of K application scenarios. Utility can be used to reflect the effect of the communication network. For example, the utility can be determined by the traffic demand and / or the service capability of the communication system. For example, the intuitive representative indicators of the utility can be throughput, the number of connected users, etc. The higher the throughput, the greater the utility. For example, the utility can also be determined by M different performance indicators shown below. For example, γ = {γ1, γ2, .....γM} represents the vector of the service capability of the communication network, which is composed of M different performance indicators. For example, γ1 represents throughput, γ2 represents delay, γ3 represents the maximum number of users, etc., which are not listed here one by one. Then the utility of the k-th type of traffic μk depends on its quality of service (QoS) requirements and / or γ.

[0110] For example, the relationship between μk and γ can be linear. For example, for some M-dimensional vector βk, μk = βkT × γ. An M*K-dimensional utility matrix Β = {β1, β2, ..., βk} can be defined, from which μ = Βγ can be obtained. Therefore, by defining a weight vector w = Βλ, the carbon efficiency can be obtained as shown in Equation (3).

[0111] η_CE=(wT×γ) / Q (3)

[0112] Formulas (2) and (3) above use different mathematical expressions to express carbon efficiency. Formulas (2) and (3) can be equivalent. For example, the numerator in Formula (2) can be considered as a linear weighted sum of the weights and utilities of different application scenarios. Formula (3) specifically provides a method for calculating utility. For example, the utility of a scenario is equal to the weighted sum of the weights of multiple performance indicators and the values ​​of the performance indicators, that is, μ = Βγ.

[0113] The above formulas (1) to (3) are illustrated by taking the carbon efficiency as an example to indicate the unit service level brought by the unit carbon emission of the communication network element. For example, the carbon efficiency may also satisfy any one of the following formulas (4) to (6):

[0114] Carbon efficiency = carbon emissions / service level (4)

[0115] η_CE=Q / (λT×μ) (5)

[0116] η_CE=Q / (wT×γ) (6)

[0117] The specific descriptions of formulas (4) to (6) refer to formulas (1) to (3) and will not be described in detail here.

[0118] Based on the above introduction to carbon intensity and carbon emission efficiency, for the two indicators of carbon intensity and carbon emission efficiency, since the energy management system cannot know the network traffic situation or service level, after the performance management functional entity obtains the carbon emissions or carbon dioxide equivalent collected by the energy management system, the performance management functional entity still needs to perform secondary processing, such as calculating the measurement values ​​of the two indicators based on the definition of the indicators.

[0119] 6. Process for optimizing carbon emission efficiency in existing technologies:

[0120] As shown in FIG1 , the process of optimizing carbon emission efficiency in the prior art is as follows:

[0121] S101: The green energy management function sends a request to the performance management function to monitor the green energy index of a certain network element.

[0122] The request may include the network element identifier, start and end times, and the name of the green energy indicator. The network element identifier indicates the monitored object, such as a base station. The start and end times are optional parameters and indicate the time period for measuring the green energy indicator. The green energy indicator name refers to the name of the measurement or statistical indicator used to measure green energy usage.

[0123] Green energy indicators can be collected from the site energy management system through configuration management functions. These indicators include green energy usage information, such as green energy usage percentage (the proportion of green energy consumption in total energy consumption), green energy usage (green energy consumption during the start and end time), green energy supply (calculated or estimated green energy supply during the start and end time, determined by sunlight conditions during the start and end time), carbon emissions (carbon emissions during the start and end time), and carbon intensity (the equivalent amount of carbon dioxide emitted per unit of activity). Green energy indicators, such as carbon emission efficiency, can also be obtained by performing secondary processing on the network management side of the green energy usage information collected directly from the site energy management system.

[0124] S102 , the performance management function obtains location information of the network element corresponding to the network element identifier from the configuration management function according to the network element identifier, and determines the name of the green energy usage information that needs to be collected in the site energy management system according to the green energy indicator name.

[0125] The green energy usage information may be the green energy indicator itself, or it may be data that needs to be collected in the site energy management system in order to calculate the green energy indicator (such as carbon emission efficiency).

[0126] S103: The performance management function collects green energy usage information through the site energy management system.

[0127] Green energy usage information may include green energy usage percentage, green energy usage, green energy (remaining) available amount, carbon emissions, etc. Carried parameters may include measurement start and end time (optional), green energy usage information name, and network element location.

[0128] The location of network elements is used to identify the corresponding energy system in the site energy management system. For example, network elements (managed objects) on the network side refer to base station equipment, while managed objects on the energy side refer to the solar panels, mains power, and batteries that power the base station equipment. While the two systems use different identifiers for managed objects, managed objects are physically linked. For example, solar panels are deployed alongside base station equipment. Therefore, location information can be used to link managed objects on both sides.

[0129] S104: The site energy management system determines the energy systems at the same location according to the location of the network element, and collects energy consumption information within the required time period (if any).

[0130] S105 , the site energy management system sends the green energy usage information value to the performance management function.

[0131] S106 , the performance management function determines a green energy index according to the green energy usage information value.

[0132] The green energy usage information value may include the value of the green energy usage ratio (such as 60%), green energy usage (such as 2 kWh), green energy supply (such as 5 kWh), carbon emissions (such as 3 kg of CO2eq, CO2eq represents carbon dioxide equivalent emissions), carbon intensity (such as 3 kg of CO2eq), etc. The green energy index is determined based on the green energy usage information value. The green energy index can be the green energy usage information value itself, or obtained by secondary processing and calculation of the green energy usage information value, and matches the two corresponding relationships between the green energy index and the green energy usage information explained in S101.

[0133] S107: The performance management function sends the green energy index to the green energy management function.

[0134] S108, the green energy management function determines whether to issue a green energy ratio adjustment instruction based on the green energy index.

[0135] After obtaining the green energy index value, the green energy management function compares it with the required value, where the required value can be specified by the cross-domain management system itself or obtained by receiving external requirements such as a service-level agreement (SLA).

[0136] S109: The green energy management function sends a green energy ratio adjustment instruction to the configuration management function.

[0137] The green energy ratio adjustment indication information is used to clearly adjust the green energy ratio of the network element and may include the green energy ratio requirement.

[0138] S110 , the configuration management function determines the green energy proportion requirement according to the green energy proportion adjustment instruction.

[0139] If the configuration management function entity has not previously received a green energy percentage requirement, or the green energy management function has new requirements for green energy percentage, these requirements may be included in the green energy percentage adjustment instruction message and delivered together. If the configuration management function entity has already configured the green energy percentage requirement for this network element, the green energy percentage adjustment instruction message may not include the green energy percentage requirement.

[0140] S111 , the configuration management function sends a request for adjusting the green energy ratio to the site energy management system.

[0141] The request includes the location of the network element, the green energy ratio requirement, and the start and end time periods. The location of the network element is used to identify the recipient of green energy, and the green energy ratio requirement is the green energy ratio allocated to this network element.

[0142] S112: The site energy management system performs green energy distribution adjustment.

[0143] Optionally, the proportion of green energy is adjusted by adjusting the power supplied by the solar photovoltaic panels.

[0144] S113, the site energy management system sends the green energy ratio adjustment execution result to the configuration management function.

[0145] S114 , the configuration management function sends the green energy proportion adjustment execution result to the green energy management function based on the green energy proportion adjustment execution result.

[0146] Understandably, existing technologies improve carbon emission efficiency by adjusting the green energy allocation / scheduling strategy of the site energy management system, for example, by increasing the proportion of green energy supply. However, the green energy allocation or scheduling capabilities of the site energy management system are limited. For example, the solar energy captured by the photovoltaic panels installed on a base station can only be used by that base station. Even if the base station fully utilizes solar energy during energy consumption, when the lighting conditions are favorable, the solar energy supply may exceed the base station's energy consumption, resulting in insufficient solar energy utilization and, in turn, preventing further improvements in carbon emission efficiency.

[0147] In response to the above technical problems, the embodiments of the present application propose the following technical solutions.

[0148] The technical solution in this application will be described below with reference to the accompanying drawings.

[0149] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as wireless network (Wi-Fi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, fourth-generation (4G) mobile communication systems, such as long-term evolution (LTE) systems, world-wide interoperability for microwave access (WiMAX) communication systems, fifth-generation (5G) systems, such as new radio (NR) systems, and future communication systems.

[0150] In the embodiment of the present application, "indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. The information indicated by a certain information (such as the first indication information, the second indication information, or the third indication information below) is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, where there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can be achieved by means of the arrangement order of each piece of information agreed in advance (such as specified in the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each piece of information can be identified and indicated uniformly to reduce the indication overhead caused by indicating the same information separately.

[0151] In addition, the specific indication method can also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of the various indication methods can be referred to the prior art and will not be repeated herein. As can be seen from the above, for example, when it is necessary to indicate multiple information of the same type, there may be a situation where the indication methods for different information are different. In the specific implementation process, the required indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood to cover various methods that can enable the party to be indicated to obtain the information to be indicated.

Among them, "saving" can mean saving in one or more memories. The one or more memories can be set separately or integrated in an encoder or decoder, a processor, or a communication device. The one or more memories can also be partially set separately and partially integrated in a decoder, a processor, or a communication device. The type of memory can be any form of storage medium, and the embodiments of the present application do not limit this.

[0154] The "protocol" involved in the embodiments of the present application may refer to a protocol family in the communication field, a standard protocol with a similar protocol family frame structure, or a related protocol used in future communication systems. The embodiments of the present application do not make specific limitations on this.

[0155] In the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that the device will perform corresponding processing under certain objective circumstances. It does not limit the time, nor does it require the device to perform judgment actions when implemented, nor does it mean that there are other limitations.

[0156] In the description of the embodiments of the present application, unless otherwise specified, " / " indicates that the objects associated with each other are in an "or" relationship. For example, A / B can represent A or B. "And / or" in the embodiments of the present application is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural. In addition, in the description of the embodiments of the present application, unless otherwise specified, "multiple" refers to two or more than two. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple. In addition, in order to facilitate the 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 basically the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit differences. At the same time, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. 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 design. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way for easy understanding.

[0157] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field will know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0158] To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application is first described in detail using the communication system shown in Figure 2 as an example. For example, Figure 2 is a schematic diagram of the architecture of a communication system applicable to the method provided in the embodiments of the present application.

[0159] As shown in Figure 2, the communication system may include: multiple management functions (also called management function entities, management service providers) and network elements in the service domain. For example, the multiple management functions may be a first management function, a second management function, ..., and an Nth management function, where N is a positive integer. These management functions may be network elements / entities in the management domain, used to manage network elements in the service domain. The network elements in the service domain may be the first network element, the second network element, ..., and the Mth network element in the service domain, where M is a positive integer.

[0160] The communication system of the embodiment of the present application is applicable to two system architectures, one is the 3GPP network architecture, and the other is the open radio access network (O-RAN) network architecture.

[0161] As shown in Figure 3, the 3GPP network architecture primarily includes a green energy management function, a network autonomous management function, a configuration management function, a performance management function, a load balancing optimization function, a green energy balancing function, and a radio access network (RAN). The multiple management function network elements in the aforementioned communication system may include the green energy management function, the network autonomous management function, the configuration management function, the performance management function, the load balancing optimization function, and the green energy balancing function in the 3GPP network architecture, and the network element in the service domain may be the RAN in the 3GPP network architecture.

[0162] Specifically, the green energy management function is used for green energy management, can monitor green energy indicators, and decide whether to call the management service provided by the SON management function. In the embodiment of the present application, it can be regarded as the caller of the service provided by the SON management function.

[0163] The network autonomous management function can be, for example, a self-organizing network (SON) management function. The SON management function can be divided into centralized SON, distributed SON, and hybrid SON based on the different deployments of the SON algorithm. As shown in Figure 4, centralized SON can be further divided into cross-domain-centralized SON and single-domain-centralized SON. Hybrid SON means that the SON algorithm can be executed at two or more different layers. The SON algorithm may include functions such as monitoring the network, analyzing management data, deciding on solutions, executing solutions, and evaluating whether the problem has been resolved. The SON management function implements the management of the SON, such as turning SON functions on and off, formulating policies, and evaluating SON performance. The deployment of the SON management function can be at the cross-domain centralized layer or the single-domain centralized layer, which is not limited by the present invention.

[0164] The configuration management function is used to manage the configuration of core network elements or base station network elements.

[0165] Performance management measures the performance of core network elements or base station elements, such as latency and throughput. It also measures green energy indicators such as carbon emissions, carbon efficiency, and green energy supply.

[0166] The load balancing optimization function may be, for example, a load balancing optimization (LBO) function, which is used to implement the execution body of the LBO management service, i.e., the managed object. When the LBO management service of the SON management function is invoked, such as modifying the handover trigger parameters, the LBO function configuration parameters are updated.

[0167] RAN equipment is also called access network device. The access network device can specifically be a next-generation mobile communication system, such as a 6G access network device, such as a 6G base station, or in the next-generation mobile communication system, the access network device can also have other naming methods, which are all included in the protection scope of the embodiments of this application, and this application does not impose any restrictions on this. Alternatively, the access network device can also include 5G, such as a gNB in ​​a new radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in 5G, or it can also be a network node constituting a gNB, a transmission point (TRP or transmission point, TP) or a transmission measurement function (TMF), such as a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), an RSU with base station function, or a wired access gateway, or a 5G core network element, etc. Alternatively, the access network device may also include: an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, wearable devices, vehicle-mounted devices, etc.

[0168] Among them, the CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH). It can be understood that the network device can be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into a network device in the access network RAN, or the CU can be divided into a network device in the core network CN, and there is no limitation here.

[0169] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0170] As shown in Figure 5, the O-RAN network architecture mainly includes the service management and orchestration module (SMO), the non-real time RAN intelligent controller (Non-RT RIC), the near-real time RAN intelligent controller (Near-RT RIC), the open centralized unit (O-CU), and the open distributed unit (O-DU). The multiple management function network elements in the above communication system may include the SMO module, the Non-RT RIC module, and the Near-RT RIC module in the O-RAN network architecture, and the network elements in the service domain may include the O-CU and O-DU in the 3GPP network architecture.

[0171] Among them, service management orchestration is used to manage the radio access network RAN ​​domain. Non-RT RIC is an internal module of SMO, which supports the management of RAN, such as issuing configuration policies and ML model management. Since it is deployed in the management layer, it is non-real-time. Near-RT RIC can provide near-real-time RAN radio access network control optimization. O-CU is the CU controller in the ORAN architecture, which can be further divided into the control plane of the O-RAN central unit (O-RAN central unit-control Plane, O-CU-CP) and the user plane of the O-RAN central unit (O-RAN central unit-user plane, O-CU-UP). O-DU is the DU controller in the O-RAN architecture.

[0172] The above network elements can be replaced by terminals, which perform load transfer between devices.

[0173] A terminal may also be called user equipment (UE), an access terminal, a subscriber unit, a user station, a mobile station (MS), a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The terminal in the embodiments of the present application can be a mobile phone, a cellular phone, a smart phone, a tablet computer, a wireless data card, a personal digital assistant (PDA), a wireless modem, a handheld device (handset), a laptop computer, a machine type communication (MTC) terminal, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a smart home device (for example, a refrigerator, a television, an air conditioner, an electric meter, etc.), an intelligent robot, a robotic arm, a workshop equipment, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a vehicle-mounted terminal, a roadside unit with terminal function, or a wireless terminal in a smart city. The terminal device of the present application may also be an onboard module, onboard module, onboard component, onboard chip or onboard unit built into a vehicle as one or more components or units. The terminal device may also be other devices with terminal functions, for example, the terminal device may also be a device that functions as a terminal in D2D communication.

[0174] The embodiments of this application do not limit the device form factor of the terminal. The device used to implement the terminal's function can be a terminal; it can also be a device that supports the terminal in implementing the function, such as a chip system. The device can be installed in the terminal or used in conjunction with the terminal. In the embodiments of this application, the chip system can be composed of a chip or include a chip and other discrete components.

[0175] In the above system, the value of at least one green energy indicator of the first network element is obtained through the first management function, the green energy usage of the first network element is analyzed based on the green energy indicator, and instruction information is sent. The instruction information is used to instruct the first network element to perform green energy-based load transfer between network elements based on the value of the at least one green energy indicator. In this way, the utilization rate of green energy can be improved when green energy cannot be flexibly allocated across communication devices, thereby improving the carbon emission efficiency of communication devices. In addition, the green energy-based load transfer in the embodiments of the present application can also be green energy-based load adjustment. Through green energy-based load transfer or load adjustment, a balance between green energy supply and energy consumption can be achieved.

[0176] The embodiments of this application do not limit the device form factor of the network device. The device used to implement the function of the network device can be a network device; it can also be a device that supports the network device to implement the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device. In the embodiments of this application, the chip system can be composed of chips or can include chips and other discrete components.

[0177] The following, in conjunction with Figures 6-10, describes in detail the interaction process between the various network elements / devices in the above-mentioned communication system through a method embodiment. The green energy-based load transfer method provided in the embodiment of the present application can be applied to the above-mentioned communication system and specifically applied to the various scenarios / processes mentioned in the above-mentioned communication system, which are described in detail below.

[0178] Figure 6 is a flow chart of a load transfer method based on green energy provided by an embodiment of the present application. The load transfer method based on green energy is applicable to the above communication system, and mainly involves interaction between the first management function and the first network element.

[0179] As shown in FIG6 , the load transfer method based on green energy is applied to the first management function, and the specific process is as follows:

[0180] S601: A first management function obtains a value of at least one green energy indicator of a first network element.

[0181] The first management function may be a network autonomous SON management function in a 3GPP network architecture or a near real-time wireless intelligent controller module in an O-RAN network architecture. The first network element may be any network element in a 3GPP network architecture or an O-RAN network architecture, such as a base station, a user port function (UPF), and an access and mobility management function (AMF). The green energy indicator is used to indicate the usage of green energy. The source of the green energy indicator may be the service profile in the service level agreement (SLA). If it is a slice-level or network-wide indicator requirement, the green energy indicator requirements of the subnet or network element may be further decomposed.

[0182] The value of the green energy indicator can be directly collected from the site energy management system, that is, the green energy usage information, or it can be obtained through secondary processing and calculation of the green energy usage information collected from the site energy management system, such as carbon emission efficiency.

[0183] Optionally, the at least one green energy indicator includes at least one of the following: carbon emission efficiency, green energy supply, energy consumption, green energy usage, green energy power, the proportion of green energy consumption in total energy consumption, remaining available green energy, carbon emissions, and carbon intensity. The above green energy indicators can be used to accurately analyze green energy usage. Of course, the corresponding indicator can be selected based on specific circumstances, and there is no limitation to this. For example, when the first network element is a base station and load transfer is performed on the base station based on the green energy indicator, the at least one green energy indicator can include carbon emission efficiency, green energy supply, and energy consumption.

[0184] S602: The first management function sends instruction information.

[0185] The indication information is used to instruct the first network element to perform load transfer based on green energy between network elements based on a value of at least one green energy indicator.

[0186] S603: The first network element receives the indication information.

[0187] The green energy indicator is used to indicate the usage of green energy, and the indication information is used to instruct the first network element to perform load transfer between network elements based on green energy.

[0188] S604: The first network element performs green energy-based load transfer between network elements based on the instruction information.

[0189] S602 is explained in detail below.

[0190] Optionally, the indication information is used to indicate a first load amount that needs to be transferred between the first network element and the second network element based on the green energy indicator. The indication information may include an identifier of the first network element, an identifier of the second network element, and the first load amount, and the second network element may be a network element of the same functional type as the first network element.

[0191] It can be understood that the identifier of the first network element can be an identifier such as letters, numbers or symbols that can uniquely identify the first network element, and the identifier of the second network element can be an identifier such as letters, numbers or symbols that can uniquely identify the second network element. The load transfer amount can be obtained by internal analysis of the SON management function, or it can be obtained through management data analysis service (multiservice distributed access system solution, MDAS) or network twin simulation, and the present invention does not limit it. The value of the first load amount can be a percentage, for example, 50% of the load of the first network element is transferred to the second network element, or it can have a suitable value according to the specific type of network element. For example, when the first network element is a base station, the load amount can be represented by the number of terminal device connections. When the first network element is a UPF or AMF, the load amount can be represented by the number of protocol data unit (PDU) sessions or the number of terminal device connections.

[0192] The first management function instructs a first network element to transfer green energy-based loads to a second network element of the same functional type, and instructs the first load amount to be transferred between the first and second network elements. The first management function can independently determine the transfer amount between the first and second network elements, and between the first and second network elements, rather than the first network element itself. This reduces device-side overhead.

[0193] Optionally, the green energy-based load transfer method may further include: before sending the indication information to the first network element, obtaining energy usage information of each of multiple network elements related to the first network element, and determining, based on the energy usage information of each of the multiple network elements, a second network element from the multiple network elements to which the load of the first network element can be transferred.

[0194] It is understood that the multiple network elements associated with the first network element may be network elements of the same functional type as the first network element, network elements with a close physical distance, and / or network elements with overlapping signal coverage. Based on energy usage, a second network element capable of load transfer from the first network element is selected from the multiple network elements to implement green energy-based load transfer of the first network element. For example, the SON management function identifies multiple network elements associated with network element 1, obtains the energy usage of each of the multiple network elements, and selects network element 2 from the multiple network elements to which network element 1 can perform load transfer.

[0195] The energy usage of each of the multiple network elements may include: the value of each of the multiple network elements' green energy indicators, and the difference between the maximum or minimum value in the threshold range of the respective green energy indicators. The load transfer between the second network element and the first network element is as follows: the difference between the value of the green energy indicator of the first network element and the minimum value in the threshold range of the green energy indicator matches the difference between the value of the green energy indicator of the second network element and the maximum value in the threshold range of the green energy indicator; or the difference between the value of the green energy indicator of the first network element and the maximum value in the threshold range of the green energy indicator matches the difference between the value of the green energy indicator of the second network element and the minimum value in the threshold range of the green energy indicator.

[0196] It is understood that the above-mentioned matching can be that the difference between the green energy index value of the first network element and the minimum value within the threshold range of the green energy index is a negative value, and the difference between the green energy index value of the second network element and the maximum value within the threshold range of the green energy index is a positive value. Alternatively, the difference between the green energy index value of the first network element and the maximum value within the threshold range of the green energy index is a positive value, and the difference between the green energy index value of the second network element and the minimum value within the threshold range of the green energy index is a negative value. Alternatively, the two differences can be equal or similar. In this way, the second network element that can transfer load with the first network element can be accurately screened.

[0197] Among them, the green energy indicator can be as described in S601, and will not be elaborated here. For example, the SON management function obtains the carbon emission efficiency / carbon intensity measurement value of base station 1, identifies a list of multiple base stations adjacent to base station 1, and collects the carbon emission efficiency / carbon intensity measurement values ​​of each of the multiple base stations. If the carbon emission efficiency / carbon intensity measurement value of base station 1 is higher than the maximum value in the threshold range of carbon emission efficiency / carbon intensity, it is determined whether there is a base station 2 among the multiple adjacent base stations whose carbon emission efficiency / carbon intensity measurement value is lower than the minimum value in the threshold range of carbon emission efficiency / carbon intensity. When there is a base station 2 that meets the requirements among the multiple adjacent base stations, the SON management function sends an indication message to base station 1 and base station 2. The indication message is a load adjustment strategy, which is used to transfer part of the load of base station 1 to base station 2 without allowing the carbon emission efficiency / carbon intensity measurement value of base station 2 to exceed the maximum value in the threshold range of carbon emission efficiency / carbon intensity, so that the carbon emission efficiency / carbon intensity of base station 1 is reduced.

[0198] Alternatively, the energy usage of each of the multiple network elements may be the difference between the green energy supply and energy consumption of each of the multiple network elements. The load transfer between the second network element and the first network element may be performed by matching the difference between the green energy supply and energy consumption of the first network element with the difference between the green energy supply and energy consumption of the second network element.

[0199] It is understood that the second network element can be selected based on the difference between the green energy supply and energy consumption of multiple network elements. The above matching can be that the difference between the green energy supply and energy consumption of the first network element is negative, and the difference between the green energy supply and energy consumption of the second network element is positive, that is, the green energy supply of the first network element is lower than the energy consumption, and the green energy supply of the second network element is higher than the energy consumption. Alternatively, the difference between the green energy supply and energy consumption of the first network element is positive, and the difference between the green energy supply and energy consumption of the second network element is negative, that is, the green energy supply of the first network element is higher than the energy consumption, and the green energy supply of the second network element is lower than the energy consumption. The two differences can also be equal or similar. In this way, the second network element that can transfer load with the first network element can be accurately selected.

[0200] For example, the SON management function obtains the green energy supply and energy consumption of base station 1, identifies a list of multiple base stations adjacent to base station 1, and collects the green energy supply and energy consumption of each of these base stations. If base station 1's green energy supply is lower than its energy consumption, the function determines whether there is a base station 2 among the multiple adjacent base stations whose green energy supply is higher than its energy consumption. If a base station 2 among the multiple adjacent base stations meets the requirements, the SON management function sends an instruction to base stations 1 and 2, which is a load adjustment policy used to transfer part of base station 1's load to base station 2.

[0201] Furthermore, if there are multiple second network elements capable of load transfer with the first network element, a portion of the load of the first network element can be distributed across the multiple second network elements. For example, if it is found that the green energy supply of multiple base stations 2 exceeds their energy consumption, the SON management function can distribute a portion of the load of base station 1 to multiple other base stations 2, taking into account the impact of adjusting the network load on network service quality.

[0202] For another example, if the green energy supply of base station 1 is higher than its energy consumption, it is determined whether there is a base station 2 among multiple neighboring base stations whose green energy supply is lower than its energy consumption. If there is a base station 2 among the multiple neighboring base stations that meets the requirements, the SON management function sends an indication information to base station 1 and base station 2. The indication information is a load adjustment strategy, which is used to transfer part of the load of base station 2 to base station 1.

[0203] Furthermore, if there are multiple second network elements capable of load transfer with the first network element, a portion of the load of the first network element can be distributed across these multiple second network elements. For example, if the green energy supply of multiple base stations 2 is found to be lower than their energy consumption, the SON management function can transfer a portion of the load of these multiple base stations 2 to base station 1, taking into account the impact of network load adjustment on network service quality. This balance between energy consumption and green energy supply can be achieved by adjusting the load between adjacent network elements, for example, increasing the load of base stations with sufficient green energy supply, thereby optimizing carbon efficiency.

[0204] Optionally, the indication information is used to instruct the load balancing optimization function to perform load balancing based on green energy between network elements, and the load balancing optimization function is deployed in the first network element. The indication information includes at least one of the following: an identifier of the load balancing optimization function and green energy reference indication information.

[0205] It is understood that the load balancing optimization function can be an LBO function, which can be a load balancing optimization execution entity used for self-optimizing load balancing based on green energy to achieve a balance between energy consumption and green energy supply. The identifier of the LBO function can be an identifier such as a letter, number, or symbol that uniquely identifies the LBO function. The first management function directly sends an indicative configuration policy to the LBO function deployed in the first network element. The destination of the load transfer is not specified, but the LBO function makes its own determination. The purpose of the transfer can be to optimize carbon emission efficiency. The green energy reference indication information is used to indicate whether to perform green energy-based load transfer between network elements based on green energy indicators. For example, when the value of the green energy reference indication information indicates "yes", such as "1", it indicates that the first network element should consider the green energy indicator when making load balancing adjustments. When the value of the green energy reference indication information indicates "no", such as "0", it indicates that the first network element does not need to consider the green energy indicator when making load balancing adjustments.

[0206] In this way, the first network element can make judgments based on its own actual situation, and thus can perform load balancing based on green energy indicators more dynamically and flexibly.

[0207] Optionally, the first management function requests the second management function to modify the load balancing optimization function attributes, and the modified load balancing optimization function attributes indicate that the load balancing optimization function needs to perform load balancing optimization based on green energy, wherein the second management function can be a configuration management function and the load balancing optimization function attributes can be new parameters, for example, new green energy reference indication information is added, and the value of the green energy reference indication information is changed from "0" to "1", indicating that the LBO function needs to perform load balancing optimization based on green energy.

[0208] For example, the first management function sends a request to the configuration management function to modify the LBO function attributes. The request may include the LBO function identifier and green energy reference indicator information, as well as the value range of the green energy indicator. The configuration management function modifies the LBO function attributes (a non-standard interface), changing the value of the green energy reference indicator information from "0" to "1." The LBO function then performs green energy-based load balancing optimization. This means that when deciding whether to switch a terminal device to a cell or base station, the impact of the handover on the cell or base station's green energy indicator will be considered.

[0209] In another possible design, the indication information is used to instruct a green energy balancing function to perform load transfer based on green energy between network elements, where the green energy balancing function is deployed in a first network element. The indication information includes at least one of the following: an identifier of the green energy balancing function and green energy reference indication information, where the green energy balancing function is used to manage the balance between green energy supply and energy consumption, and the green energy reference indication information is used to indicate whether to perform load transfer based on green energy between network elements based on a green energy indicator.

[0210] It is understood that the green energy balancing function can be added as a new management object to optimize the balance between green energy supply and network element energy consumption. The green energy balancing function can be identified by a letter, number, or symbol that uniquely identifies the green energy balancing function. The first management function directly sends an indicative configuration policy to the green energy balancing function deployed in the first network element. This policy does not specify the destination for load transfer, but rather leaves it to the discretion of the green energy balancing function to instruct the first network element to consider green energy indicators when making load transfer adjustments. This means that the purpose of the transfer can be to optimize carbon emission efficiency.

[0211] Optionally, the first management function requests the second management function to modify a green energy balancing function attribute, where the modified green energy balancing function attribute indicates that the green energy balancing function needs to perform load balancing optimization based on green energy, wherein the second management function may be a configuration management function. The green energy balancing function attribute may be a newly added parameter, such as adding green energy reference indication information and changing the value of the green energy reference indication information from "0" to "1", indicating that the green energy balancing function needs to perform load balancing optimization based on green energy.

[0212] For example, the first management function sends a request to the configuration management function to modify the attributes of the green energy balancing function. The request may include the green energy balancing function's identifier and green energy reference indication information, as well as the value range of the green energy indicator. The configuration management function modifies the green energy balancing function attributes. By changing the value of the green energy reference indication information from "0" to "1," the green energy balancing function performs green energy-based load balancing optimization. This means that when deciding whether to switch a terminal device to a cell or base station, the impact of the handover on the cell or base station's green energy indicator will be considered.

[0213] Optionally, the indication information may further include a threshold range for at least one green energy indicator. The threshold range for the green energy indicator is used to define a standard value for green energy measurement or statistics. The measured green energy indicator value is analyzed using the threshold range for the at least one green energy indicator to determine whether the measured green energy indicator value meets the requirement. For example, the difference between green energy supply and base station energy consumption may be analyzed to determine whether green energy balance can be achieved by adjusting the base station load.

[0214] For example, the SON management function analyzes the measured value of the green energy indicator. When it monitors that the measured value of the carbon emission efficiency of base station 1 is not within the threshold range, the SON management function directly sends an indicative configuration strategy, that is, instruction information, to the LBO function or green energy balancing function deployed in base station 1, requiring base station 1 to consider the impact on carbon emission efficiency when making load balancing adjustments.

[0215] Optionally, before S602 , the load transfer method based on green energy may further include: determining that a value of a first green energy indicator among at least one green energy indicator is not within a threshold range.

[0216] The first green energy indicator may be any green energy indicator among the at least one green energy indicator, for example, a measurement of carbon emission efficiency. If the value of the first green energy indicator among the at least one green energy indicator is outside the threshold range, indicating that the value of the first green energy indicator is low or high, it is necessary to send an indication to trigger a green energy-based load shift.

[0217] For example, the first management function analyzes the values ​​of green energy indicators and determines indication information. If the measured value of the carbon emission efficiency of network element 1 is not within a threshold range, the first management function identifies network element 1 as a network element requiring green energy balancing adjustment and determines the adjustment strategy, i.e., the indication information.

[0218] Optionally, sending the indication information may include: sending the indication information to a second management function related to the first network element.

[0219] The second management function related to the first network element can be a configuration management function, which can be used to forward indication information to the first network element, or configure parameters of the load balancing optimization function or the green energy balancing function based on the indication information, so that the first network element can accurately execute the indication information.

[0220] For example, the first management function sends an indication message to the configuration management function. After the first management function determines the indication message (load adjustment policy), it sends the identifier of the network element 1 from which the load needs to be moved (the source network element identifier), the identifier of the network element 2 to which the load is moved (the destination network element identifier), and the amount of load to be transferred to the configuration management function. The configuration management function sends the indication message to the network element 1, and can also send the indication message to the network element 2 that can transfer the load with the network element 1. The configuration management function configures the received policy to the relevant network element 1 and network element 2 (this interface is a non-standard interface), and then the network element 1 and network element 2 in the RAN / CN domain perform load transfer according to the configuration policy of the configuration management function.

[0221] When the first management function cannot communicate directly with the first network element, the first management function may indirectly instruct or configure the first network element through the second management function.

[0222] In another possible design, the first management function may include a network autonomous management function and a near real-time wireless intelligent controller module.

[0223] Optionally, when the first management function is a near real-time wireless intelligent controller module, the first network element may include a first base station; and obtaining the value of at least one green energy indicator of the first network element may include obtaining a traffic indicator of a terminal device connected to the first base station, and determining the value of at least one green energy indicator generated by the terminal device based on the traffic indicator of the terminal device.

[0224] It is understood that the near-real-time wireless intelligent controller module monitors the green energy indicators of the first base station and neighboring base stations, and monitors the traffic indicators of the terminal devices served by the base station. The traffic indicator may, for example, be the proportion of the terminal device traffic in the total base station traffic. If the first management function is the near-real-time wireless intelligent controller module, the indication information may include a traffic diversion strategy.

[0225] Optionally, a value of at least one green energy indicator of the first base station is obtained, and it is determined whether a value of the at least one green energy indicator is outside a threshold range.

[0226] Exemplarily, the near-real-time wireless intelligent controller module obtains the value of at least one green energy indicator of base station 1. If the value of carbon emission efficiency among the values ​​of at least one green energy indicator is not within a threshold range, the difference between the green energy supply and the base station energy consumption is analyzed. The terminal device traffic accessed by base station 1 and the total base station traffic are obtained through the open centralized unit and / or the open distributed unit, and the proportion of the terminal device traffic in the total base station traffic is calculated. Since the proportion of the terminal device traffic in the total base station traffic is equal to the proportion of the terminal device green energy consumption in the total green energy consumption of the base station, the terminal device-level green energy consumption can be derived.

[0227] In this way, by monitoring the flow index of the terminal device served by the first base station and calculating the terminal device-level green energy index of the first base station, the flow transfer strategy can be determined more precisely.

[0228] Among them, the indication information is used to indicate the terminal devices that need to be migrated based on green energy between the first base station and the second base station. The indication information may include the identifier of the first base station, the identifier of the second base station, and the identifier of the terminal devices that need to be migrated among the terminal devices accessed by the first base station.

[0229] For example, if the near real-time wireless intelligent controller module determines that the green energy consumption of the terminal devices connected to base station 1 (or CU1) is too high, that is, exceeds the threshold range, the terminal devices connected to base station 1 are transferred to base station 2 (or other CU), that is, the number of terminal devices connected to base station 1 is reduced, and the load of base station 1 is reduced. If the green energy consumption of the terminal devices connected to base station 1 (or CU1) is too low, that is, it does not reach the lowest value of the threshold range, the terminal devices connected to base station 2 (or other CU) are transferred to base station 1 (or CU1), that is, the number of terminal devices connected to base station 1 is increased, and the number of terminal devices connected to base station 2 is reduced, so as to achieve the effect of load balancing based on green energy indicators. Among them, base station 2 can be one or more, which is not limited here.

[0230] It can be understood that by migrating the number of terminal devices connected to the first base station based on green energy, the traffic between multiple base stations can be intelligently controlled, thereby improving the user experience.

[0231] An embodiment of the present application provides another green energy-based load transfer method, which is applied to a third management function and includes: obtaining a threshold range of a green energy indicator; and sending a green energy balancing service request to the first management function. The green energy balancing service request may include at least one of the following: an identifier of the first network element and the threshold range of the green energy indicator.

[0232] It is understandable that the third management function can be a green energy management function or a non-real-time wireless intelligent controller module, which obtains the threshold range of the green energy indicator, i.e., the green energy indicator requirement. The threshold range of the green energy indicator can be specified by the cross-domain management system itself, or can be obtained by receiving external requirements such as the service profile in the SLA. The green energy balancing service request is used to request the first management function to trigger the green energy balancing service, requesting the green energy balancing service from the first management function through the third management function, and carrying the identifier of the first network element and the threshold range of the green energy indicator. The first management function then ensures the green energy indicator through load transfer based on green energy.

[0233] For example, the green energy management function obtains the threshold range of the green energy indicator and sends a request to trigger the green energy balancing self-organizing service to the SON management function. The request may include the identifier of the network element 1 and parameters of the threshold range of the green energy indicator.

[0234] For another example, the non-real-time wireless intelligent controller module obtains the threshold range of the green energy indicator and sends a request for a green energy-based traffic shifting strategy to the near-real-time wireless intelligent controller module. The request may include the identifier of base station 1, the threshold range of the green energy indicator, and the green energy reference indicator information. This green energy-based traffic shifting strategy serves the same purpose as the aforementioned green energy balancing self-organizing service. Its purpose is to intelligently control traffic between multiple cells through performance monitoring and closed-loop control.

[0235] Optionally, the third management function obtains the value of at least one green energy indicator, compares the value of the green energy indicator with a threshold range of the green energy indicator, and determines whether to trigger the green energy balancing function based on the comparison result. The determination of whether to trigger the green energy balancing function is based on site energy consumption, such as when green energy supply significantly exceeds or falls short of energy consumption.

[0236] Alternatively, the first network element may be a network element with a significant imbalance between green energy supply and actual energy consumption. If the green energy management function does not identify the first network element with a significant imbalance between green energy supply and actual energy consumption, the identifier of the first network element indicates the identifier of the network element for which the green energy management function wishes to achieve green energy self-balancing, and whether the balance is achieved is monitored and managed by the first management function.

[0237] An embodiment of the present application provides another green energy-based load transfer method, which is applied to a fourth management function and includes: receiving a measurement request for a green energy indicator value of a first network element from a first management function; and sending the green energy indicator value of the first network element to the first management function based on the measurement request.

[0238] It is understood that the fourth management function may be a performance management function, and the measurement request may include an identifier of the first network element. A measurement request for obtaining a value of a green energy indicator of the first network element, sent by the first management function, is received by the fourth management function, and the green energy indicator of the first network element is measured based on the measurement request. The green energy indicator may be obtained by direct measurement or by calculation after measurement.

[0239] For example, the SON management function sends a request to the performance management function to measure the green energy indicator value of network element 1. The request may include the identifier of network element 1. The green energy indicator here may be, but is not limited to, the green energy indicator obtained by the green energy management function. The performance management function then returns the value of the green energy indicator to the SON management function.

[0240] In this way, the fourth management function sends the value of the green energy indicator of the first network element to the first management function based on the measurement request, so that the first management function determines the indication information through the value of the green energy indicator of the first network element to realize load transfer based on green energy.

[0241] The specific implementation principles of S603-S604 are similar to those of the above S601-S602, which can be understood by reference and will not be repeated here.

[0242] The above, combined with Figure 6, illustrates the overall process of the green energy-based load transfer method provided in the embodiment of the present application. The following, combined with Figures 7-10, specifically introduces the specific process of the green energy-based load transfer method provided in the embodiment of the present application in various scenarios.

[0243] Scenario 1:

[0244] Figure 7 is a second flow chart of the load transfer method based on green energy provided in an embodiment of the present application. The load transfer method based on green energy is applicable to the above-mentioned 3GPP network architecture, and specifically involves the interaction between the network autonomous management function (i.e. the above-mentioned first management function), the green energy management function (i.e. the above-mentioned third management function), the configuration management function (i.e. the above-mentioned second management function), the performance management function (i.e. the above-mentioned fourth management function) and the network element 1 (i.e. the above-mentioned first network element). In scenario 1, the network autonomous management function analyzes the use of green energy of the first network element through green energy indicators, and instructs the first network element to perform load transfer based on green energy between network elements, which can improve the utilization rate of green energy when green energy cannot be flexibly allocated across communication equipment, thereby improving the carbon emission efficiency of communication equipment.

[0245] Specifically, as shown in FIG7 , the process of the load transfer method based on green energy is as follows:

[0246] S701: The green energy management function obtains a threshold range of a green energy indicator.

[0247] The threshold range of green energy indicators is used to clarify the standard value of green energy measurement or statistics.

[0248] It is understandable that the specific implementation of the threshold range of the green energy indicator can also refer to the relevant introduction in the above S602, which will not be repeated here.

[0249] S702 , the green energy management function sends a request to the network autonomous management function to trigger a green energy balancing self-organizing service.

[0250] The network autonomous management function may be a SON management function. The request for triggering the green energy balancing self-organizing service may include an identifier of network element 1 and a threshold range of a green energy indicator. The green energy balancing self-organizing service is a load balancing service based on green energy. Network element 1 may be a network element in the RAN domain or the CN domain.

[0251] S703 , the network autonomous management function sends a request to the performance management function to measure the value of the green energy indicator of network element 1 .

[0252] The request for measuring the value of the green energy indicator of the network element 1 may include the identifier of the network element 1. The green energy indicator here may be, but is not limited to, the green energy indicator obtained by the green energy management function.

[0253] In addition, the specific implementation of the value of the green energy indicator can also refer to the relevant introduction in the above S601, which will not be repeated here.

[0254] S704 , the performance management function returns the value of the green energy indicator to the network autonomous management function.

[0255] S705 , the network autonomous management function analyzes the value of the green energy indicator and determines indication information.

[0256] For example, when the measured value of the carbon emission efficiency of network element 1 is monitored to be outside the threshold range, the network autonomous management function determines network element 1 as a network element object requiring green energy balance adjustment and determines the adjustment strategy, i.e., instruction information.

[0257] S706: The network autonomous management function sends instruction information to the configuration management function.

[0258] S707 , the configuration management function sends instruction information to network element 1 .

[0259] After the SON management function determines the indication information (load adjustment policy), it sends the identifier of network element 1 (source network element identifier), the identifier of network element 2 (destination network element identifier), and the amount of load to be transferred to the configuration management function. The configuration management function sends the indication information to network element 1 and may also send indication information to network element 2, which can transfer load with network element 1. The configuration management function configures the received policy to the relevant network elements 1 and 2 (this interface is non-standard).

[0260] S708, network element 1 executes the instruction information.

[0261] Network element 1 and network element 2 perform load transfer according to the configuration policy of the configuration management function.

[0262] In addition, the above steps S703 - S708 may occur cyclically to reflect network autonomy.

[0263] Scenario 2:

[0264] Figure 8 is a flow chart of the third method for load transfer based on green energy provided in an embodiment of the present application. The method for load transfer based on green energy is applicable to the above-mentioned 3GPP network architecture, and specifically involves the interaction between the network autonomous management function (i.e., the above-mentioned first management function), the green energy management function (i.e., the above-mentioned third management function), the configuration management function (i.e., the above-mentioned second management function), the performance management function (i.e., the above-mentioned fourth management function), and the load balancing optimization function (i.e., deployed in the above-mentioned first network element). In scenario 2, the network autonomous management function analyzes the usage of green energy of the first network element through green energy indicators, and instructs the load balancing optimization function deployed in the first network element to perform load balancing based on green energy between network elements, so that the first network element can judge based on its own actual situation and perform load balancing based on green energy indicators more dynamically and flexibly.

[0265] Specifically, as shown in FIG8 , the process of the load transfer method based on green energy is as follows:

[0266] S801: The green energy management function obtains a threshold range of a green energy indicator.

[0267] S802 , the green energy management function sends a request to the network autonomous management function to trigger a green energy balancing self-organizing service.

[0268] S803 , the network autonomous management function sends a request to the performance management function to measure the value of the green energy indicator of network element 1 .

[0269] S804, the performance management function returns the value of the green energy indicator to the network autonomous management function.

[0270] S805, the network autonomous management function analyzes the value of the green energy indicator and determines the indication information.

[0271] The specific implementation of S801-S805 can also refer to the relevant introduction of S701-S705 above, which will not be repeated here.

[0272] S806: The network autonomous management function sends a request to the configuration management function to modify the attributes of the load balancing optimization function.

[0273] The request for modifying the attributes of the load balancing optimization function may include an identifier of the load balancing optimization function and green energy reference indication information, and may also include a value range of the green energy indicator. The load balancing optimization function may be an LBO function.

[0274] In addition, the specific implementation of the green energy reference indication information can also refer to the relevant introduction in the above S602, which will not be repeated here.

[0275] S807, the configuration management function modifies the load balancing optimization function attributes.

[0276] S808: If the green energy reference information indicates that the usage of green energy needs to be included in the reference input of the load balancing optimization, the load balancing optimization function performs the load balancing optimization based on the green energy.

[0277] The value of green energy reference information can be expressed as "yes / no," "on / off," or "0 / 1," without limitation. For example, a value of "yes," "on," or "1" indicates that green energy usage should be considered as a reference input for load balancing optimization. Green energy-based load balancing optimization means that when deciding whether to switch a terminal device to a cell or base station, the impact of the handover on the green energy indicators of the cell or base station will be considered.

[0278] In addition, the above steps S803 to S808 may occur cyclically to reflect network autonomy.

[0279] Scenario 3:

[0280] Figure 9 is a flow chart of the fourth method for load transfer based on green energy provided in an embodiment of the present application. The method for load transfer based on green energy is applicable to the above-mentioned 3GPP network architecture, and specifically involves the interaction between the network autonomous management function (i.e., the above-mentioned first management function), the green energy management function (i.e., the above-mentioned third management function), the configuration management function (i.e., the above-mentioned second management function), the performance management function (i.e., the above-mentioned fourth management function), and the green energy balancing function (i.e., deployed in the above-mentioned first network element). In scenario 3, the network autonomous management function analyzes the usage of green energy of the first network element through green energy indicators, and instructs the green energy balancing function deployed in the first network element to perform load transfer based on green energy between network elements, so that the first network element can judge based on its own actual situation and perform load transfer based on green energy indicators more dynamically and flexibly.

[0281] Specifically, as shown in FIG9 , the process of the load transfer method based on green energy is as follows:

[0282] S901: The green energy management function obtains a threshold range of a green energy indicator.

[0283] S902 , the green energy management function sends a request to the network autonomous management function to trigger a green energy balancing self-organizing service.

[0284] S903 , the network autonomous management function sends a request to the performance management function to measure the value of the green energy indicator of network element 1 .

[0285] S904: The performance management function returns the value of the green energy indicator to the network autonomous management function.

[0286] S905 , the network autonomous management function analyzes the value of the green energy indicator and determines the indication information.

[0287] The specific implementation of S901-S905 can also refer to the relevant introduction of S701-S705 above, which will not be repeated here.

[0288] S906 , the network autonomous management function sends a request to the configuration management function to modify the green energy balancing function attributes.

[0289] The request for modifying the green energy balancing function attribute may include the identifier of the green energy balancing function and green energy reference indication information, and may also include the value range of the green energy indicator.

[0290] In addition, the specific implementation of the green energy reference indication information can also refer to the relevant introduction in the above S602, which will not be repeated here.

[0291] S907, the configuration management function modifies the green energy balancing function attributes.

[0292] S908: If the green energy reference information indicates that the usage of green energy needs to be included in the reference input of the load balancing optimization, the green energy balancing function performs the load balancing optimization based on the green energy.

[0293] The value of green energy reference information can be expressed as "yes / no," "on / off," or "0 / 1," without limitation. For example, a value of "yes," "on," or "1" indicates that green energy usage should be considered as a reference input for load balancing optimization. Green energy-based load balancing optimization means that when deciding whether to switch a terminal device to a cell or base station, the impact of the handover on the green energy indicators of the cell or base station will be considered.

[0294] In addition, the above steps S903 to S908 may occur cyclically to reflect network autonomy.

[0295] Scenario 4:

[0296] Figure 10 is a flowchart of the fifth embodiment of the load transfer method based on green energy provided in the embodiment of the present application. The load transfer method based on green energy is applicable to the above-mentioned ORAN network architecture, and specifically involves the Near-RT RIC module (i.e., the above-mentioned first management function), the Non-RT RIC module (i.e., the above-mentioned third management function), and the interaction between the O-DU and the O-CU (i.e., the above-mentioned first base station). In scenario 4, the Near-RT RIC module analyzes the green energy usage of the first base station through green energy indicators, and instructs the first base station to perform green energy-based load balancing between network elements, which can intelligently control the traffic between multiple cells, thereby improving the user experience.

[0297] Specifically, as shown in FIG10 , the process of the load transfer method based on green energy is as follows:

[0298] S1001: The non-real-time wireless intelligent controller module obtains a threshold range of a green energy indicator.

[0299] S1002: The non-real-time wireless intelligent controller module sends a request for a green energy-based traffic transfer strategy to the near-real-time wireless intelligent controller module.

[0300] The request for a green energy-based traffic shifting strategy may include the identifier of base station 1, the threshold range of the green energy indicator, and green energy reference indication information. The green energy-based traffic shifting strategy here serves the same purpose as the aforementioned green energy balancing self-organizing service. The traffic shifting strategy aims to intelligently control traffic between multiple cells through performance monitoring and closed-loop control, and carries parameters such as the identifier of base station 1 and the threshold range of the green energy indicator.

[0301] S1003, the near real-time wireless intelligent controller module obtains a value of at least one green energy indicator of base station 1, and analyzes the value of at least one green energy indicator if the value of the at least one green energy indicator is not within a threshold range.

[0302] For example, analyzing the gap between green energy supply and base station energy consumption.

[0303] S1004 , the near real-time wireless intelligent controller module obtains traffic indicators of terminal devices connected to base station 1 through the open centralized unit and / or the open distributed unit.

[0304] For example, obtain the terminal device traffic accessed by base station 1 and the total base station traffic.

[0305] S1005, the near real-time wireless intelligent controller module calculates the terminal device-level traffic index based on the traffic index of the terminal device connected to base station 1, and generates a traffic transfer strategy based on the difference between the green energy supply and the base station energy consumption.
