Description

Technical Field

[0001] 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

[0002] At present, 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.

[0003] In the prior art, carbon emission efficiency is usually improved 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 obtained by the photovoltaic panels installed on the base station can only be used for the base station. Even if the base station has fully utilized solar energy during energy consumption, when the lighting conditions are excellent, the solar energy supply may be higher than the base station energy consumption, resulting in insufficient utilization of solar energy, which in turn leads to the inability to further improve carbon emission efficiency.

[0004] Therefore, how to further improve the carbon emission efficiency of communication equipment is a hot topic in current research. Summary of the invention

[0005] The embodiments of the present application provide a method and device for load transfer based on green energy, so as to further improve the carbon emission efficiency of communication equipment.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a method for load transfer is provided, the method being applied to a first management function, comprising: obtaining a value of at least one green energy indicator of a first network element, the green energy indicator being used to indicate the use of green energy. If indication information is sent, the indication information is used to instruct the first network element to perform load transfer based on green energy between network elements based on the value of the at least one green energy indicator.

[0008] Based on the method described in the first aspect, it can be known that the value of at least one green energy indicator of the first network element is obtained through the first management function, the use of green energy of the first network element is analyzed through the green energy indicator, and indication information is sent, and the indication information is used to instruct the first network element to perform load transfer based on green energy between network elements based on the value of 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.

[0009] In a possible design, the method described in the first aspect may further include: before sending the indication information, determining that the value of the first green energy indicator among at least one green energy indicator is not within a threshold range. That is, if the value of the first green energy indicator among at least one green energy indicator is not within the threshold range, it means that the value of the first green energy indicator is low or high, so it is necessary to send the indication information to trigger the load transfer based on green energy.

[0010] In a 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: 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. 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 the instruction is sent to transfer 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, which can reduce the overhead on the device side.

[0011] 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.

[0012] In a possible design scheme, the method described in the first aspect may also 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. According to the energy usage of each of the multiple network elements, determine a second network element that can transfer the load with the first network element from the multiple network elements. 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, so that the second network elements selected can interact with the first network element and can more conveniently realize load transfer based on green energy with the first network element.

[0013] The energy usage of each of the multiple network elements includes: 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 each of the green energy indicators. The load transfer between the second network element and the first network element is: 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.

[0014] In one possible design, 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, and 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.

[0015] It can be understood that the first management function directly sends an indicative configuration policy to the first network element, does not specify the destination of the load transfer, but is judged by the load balancing optimization function, so that the first network element can judge according to its actual situation and indicate whether the first network element needs to consider the green energy index when making load balancing adjustments, so that load balancing can be performed more dynamically and flexibly based on the green energy index. In addition, the load balancing optimization function defines a new attribute value, that is, reuses the existing information element implementation, which is more friendly to the support of existing standards and has lower implementation difficulty.

[0016] In another possible design, the indication information is used to instruct the green energy balancing function to perform load transfer based on green energy between network elements, and 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, and 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 green energy indicators.

[0017] It can be understood that 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 strategy to the first network element, without specifying the destination of load transfer. Instead, the green energy balancing function makes its own judgment, which allows the first network element to make a decision based on its own actual situation. Therefore, it can perform load transfer based on green energy indicators more dynamically and flexibly. In addition, the green energy balancing function newly defines a cell implementation to achieve decoupling from existing solutions and achieve more flexibility.

[0018] Optionally, the indication information may further include a threshold range of at least one green energy indicator. The threshold range of the green energy indicator is used to clarify the standard value of green energy measurement or statistics, which does not need to be determined by the first network element and can be configured to the first network element. Of course, the threshold range can also be pre-configured or pre-defined by protocol in the first network element locally without indication, so as to reduce communication overhead.

[0019] 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 implement the indication or configuration of the first network element through the second management function.

[0020] 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, which is more friendly to the support of existing standards and less difficult to implement.

[0021] 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 the flow indicator of a terminal device connected to the first base station. Determine the value of at least one green energy indicator generated by the terminal device according to the flow indicator of the terminal device. By monitoring the flow indicator of the service object terminal device under the first base station and calculating the terminal device-level green energy indicator of the first base station, the flow transfer strategy can be determined more precisely.

[0022] 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, and 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 that need to be migrated among the terminal devices connected to the first base station. 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.

[0024] Based on the method described in the second aspect, it can be known 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.

[0025] In a third aspect, a method for load transfer based on green energy is provided, the method being applied to a fourth management function, comprising: receiving a measurement request for a value of a green energy indicator of a first network element sent by a first management function, and sending the value of the green energy indicator of the first network element to the first management function based on the measurement request.

[0026] 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 a measurement request for the value of the green energy indicator of the first network element sent by the first management function, 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.

[0027] In a fourth aspect, a method for load transfer based on green energy is provided, the method being applied to a first network element, comprising: receiving indication information, where the green energy indicator is used to indicate the use of green energy, and the indication information is used to instruct the first network element to perform load transfer based on green energy between network elements. Based on the indication information, load transfer based on green energy between network elements is performed.

[0028] In a 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.

[0029] 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.

[0031] Optionally, the second network element is a network element that can transfer the load of the first network element according to the energy usage of each of the multiple network elements, and the multiple network elements are network elements related to the first network element.

[0032] The energy usage of each of the multiple network elements includes: the value of each of the multiple network elements' green energy indicators, and the difference between the maximum value or the 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: the difference between the value of the green energy indicator of the first network element and the maximum value or the minimum value in the threshold range of the respective green energy indicators matches the difference between the value of the green energy indicator of the second network element and the maximum value or the minimum value in the threshold range of the respective green energy indicators.

[0033] 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 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.

[0070] For ease of understanding, the technical terms involved in the embodiments of the present application are first introduced below.

[0071] 1. Explanation of key terms:

[0072] Carbon footprint (CO2 footprint): refers to the carbon footprint of an enterprise, activity, product or individual through transportation, food production and consumption, and

[0073] The collection of greenhouse gas emissions caused by various production processes, etc.

[0074] 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.

[0075] Green energy index: a general term for indicators used to measure the green energy usage or carbon emission performance of power equipment in communication networks due to energy consumption. Examples of specific indicators are as follows:

[0076] Proportion of green energy use: the proportion of green energy consumption in total energy consumption.

[0077] Green energy usage: the amount of green energy consumed during the start and end time.

[0078] Green energy supply: The green energy supply calculated or estimated during the start and end time, determined by the lighting conditions during the start and end time.

[0079] Carbon emission: the amount of carbon emissions during the start and end time.

[0080] Carbon intensity: the equivalent amount of carbon dioxide emitted per unit of activity.

[0081] Carbon Emission Efficiency: Carbon emission efficiency.

[0082] 2. 3GPP Standard Background:

[0083] The current 3GPP energy conservation project addresses energy usage issues in communication networks from the perspective of energy efficiency measurement and energy conservation:

[0084] Define the measurement method of 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. And reflect the customer's requirements for slice energy efficiency by adding energy efficiency parameters in the slice service profile.

[0085] Two states are defined for a cell, a network element (NE) or a network function (NF), that is, 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.

[0086] Based on the above energy-saving status, a complete energy-saving solution can include the following two steps:

[0087] Energy saving activation: Change from a non-energy saving state to an energy saving state.

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

[0089] The energy-saving state is changed by operating the above two steps.

[0090] 3. Site Energy Management System:

[0091] The site energy management system focuses on the unified management of site energy, environment and safety components. It helps maintenance personnel remotely manage sites by real-time monitoring of the performance and alarm information of related equipment, statistically analyzes site energy consumption, and provides data support suggestions for energy-saving optimization. In scenarios where mains power supply, battery power supply and green energy power supply can all exist, the management objects of the site energy management system include: energy systems, such as solar panels, mains power, UPS, batteries, diesel engines, fuel tanks and other power supply components, among which solar panels are placed according to the planned location of the base station.

[0092] 4. Definition of carbon emission efficiency standards for the communications industry:

[0093] The carbon emissions of information 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:

[0094]

[0095] EC i : represents the energy consumed by the ICT site from power source i (local, hot / cold loop, grid) per year, 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, according to 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 lead the wireless network to continue to develop in the direction of providing more business volume and better business experience with less carbon footprint. Exemplarily, the carbon efficiency can satisfy formula (1):

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

[0105] Among them, the numerator is the service level, which is used to describe the utility of communication network services. Due to the increase of emerging business types in the next generation of wireless networks, the service level can be a parameter related to the total amount of data transmission, user experience, and scenario business type. ri (scenario factor) is determined by the business type and business needs of different scenarios: such as 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 vector λ. λ={λ1,λ2,.....λk} represents the weight vectors of K different application scenarios (such as ultra-high rate, ultra-large-scale access, high mobility and low latency, ultra-low power consumption communication, etc.), and the specific value of λk is determined by the proportion of the Kth traffic (such as the proportion of the traffic in the Kth application scenario to the total traffic) and / or the importance of the Kth application scenario. K can be an integer greater than or equal to 1.

[0109] The 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 access users, etc. The higher the throughput, the greater the utility. Another example is that 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, μk and γ may be in a linear relationship, such as for some M-dimensional vector βk, μk = βkT × γ. An M*K-dimensional utility matrix B = {β1, β2, ..... βk} may be defined, through which μ = Bγ may be obtained. Therefore, by defining a weight vector w = Bλ, the carbon efficiency may be obtained as shown in formula (3).

[0111] η_CE=(wT×γ) / Q (3)

[0112] The above formula (2) and formula (3) use different mathematical expressions to express carbon efficiency. Formula (2) and formula (3) can be equivalent. For example, the numerator in formula (2) can be considered as the linear weighted sum of the weights and utilities of different application scenarios. Formula (3) specifically gives the calculation method of utility, such as 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 = Bγ.

[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 formula (4) to formula (6) refer to formula (1) to formula (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 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 of optimizing carbon emission efficiency in existing technologies:

[0120] like Figure 1 As shown, the process of optimizing carbon emission efficiency in the prior art is as follows:

[0121] S101, the green energy management function sends a request for monitoring a green energy indicator of a certain network element to the performance management function.

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

[0123] Green energy indicators can be collected from the site energy management system through the configuration management function, that is, green energy usage information, such as green energy usage ratio (the ratio of green energy consumption to total energy consumption), green energy usage (i.e., green energy consumption within the start and end time), green energy supply (the green energy supply calculated or estimated within the start and end time, determined by the light conditions within the start and end time), carbon emissions (carbon emissions within the start and end time), carbon intensity (the equivalent amount of carbon dioxide emitted per unit activity), etc. Green energy indicators can also be obtained by secondary processing and calculation of green energy usage information directly collected from the site energy management system on the network management side, such as carbon emission efficiency.

[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 index itself, or may be data that needs to be collected in the site energy management system in order to calculate the green energy index (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 the network element is used to determine the corresponding energy system in the site energy management system. For example, the network element (management object) on the network side refers to the base station equipment, and the management object on the energy side refers to the solar panels, mains power, and batteries that provide power to the base station equipment. The identification of the management objects is not universal between the two, but the management objects are related in physical location. For example, solar panels are deployed with base station equipment, so the management objects on both sides can be associated through location information.

[0129] S104, the site energy management system determines the energy system 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 according to the green energy index.

[0135] After obtaining the green energy index value, the green energy management function compares it with the required value, wherein the required value can be set 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 proportion adjustment indication information is used to explicitly adjust the green energy proportion of the network element, and may include the green energy proportion 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 received green energy percentage requirements before, or the green energy management function has new requirements for green energy percentage, it can be included in the green energy percentage adjustment indication information and sent together. If the configuration management function entity has configured the green energy percentage requirements of this network element in advance, the green energy percentage adjustment indication information may not include the green energy percentage requirements.

[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 percentage requirement and the start and end time periods. The location of the network element is used to specify the object receiving the green energy, and the green energy percentage requirement is the green energy percentage 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 proportion 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] It is understandable that in the prior art, carbon emission efficiency is improved 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 obtained by the photovoltaic panels mounted on the base station can only be used for the base station. Even if the base station has fully utilized solar energy during energy consumption, when the lighting conditions are excellent, the solar energy supply may be higher than the base station energy consumption, resulting in insufficient utilization of solar energy, which in turn leads to the inability to further improve carbon emission efficiency.

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

[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.

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 its similar expression refers to any combination of these items, including any combination of single items 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, c can be single or multiple. In addition, in order to facilitate the clear description of the technical solution of the embodiments of the present application, in the embodiments of the present application, the words "first" and "second" are used to distinguish the same or similar items with basically the same functions and effects.

[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. A person of ordinary skill in the art can appreciate that with the evolution of the 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, first Figure 2 The communication system shown in the example is used to describe in detail the communication system applicable to the embodiment of the present application. Figure 2 A schematic diagram of the architecture of a communication system applicable to the method provided in an embodiment of the present application.

[0159] like Figure 2As shown, the communication system may include: multiple management functions (also called management function entities, management service providers) and network elements of the service domain. For example, the multiple management functions may be a first management function, a second management function, ..., an Nth management function, where N is a positive integer. These management functions may be network elements / entities of the management domain, which are used to manage network elements of the service domain. The network elements of the service domain may be the first network element, the second network element, ..., the Mth network element of 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] like Figure 3 As shown, the 3GPP network architecture mainly includes green energy management function, network autonomous management function, configuration management function, performance management function, load balancing optimization function, green energy balancing function and radio access network (RAN). The multiple management function network elements in the above communication system may include the green energy management function, network autonomous management function, configuration management function, performance management function, load balancing optimization function and green energy balancing function in the 3GPP network architecture, and the network element of 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. It 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 may 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 SON algorithm execution deployment. Figure 4As shown, 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 is solved. The SON management function implements the management of SON, such as switching SON functions, formulating strategies, evaluating SON performance, etc. The deployment of SON management functions 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] The performance management function is used to measure the performance of core network elements or base station elements, such as latency, throughput, etc. It can also measure 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 executor of the LBO management service, i.e. the managed object. When the LBO management service of the SON management function is called, 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 the present application, and the present application does not make any restrictions on this. Alternatively, the access network device may also include 5G, such as a gNB in ​​a new radio (NR) system, or one or a group of (including multiple antenna panels) antenna panels of a base station in 5G, or it may also be a network node constituting a gNB, a transmission point (transmission and reception point, TRP or transmission point, TP) or a transmission measurement function (transmission measurement function, TMF), such as a centralized unit (central unit, CU), a distributed unit (distributed unit, DU), a CU-control plane (control plane, CP), a CU-user plane (user plane, UP), or a radio unit (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: access point (AP) in a wireless fidelity (WiFi) system, wireless relay node, wireless backhaul node, various forms of macro base stations, micro base stations (also called small stations), relay stations, access points, wearable devices, vehicle-mounted devices, etc.

[0168] Among them, CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). 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, or a DU node, or a device including a CU node and a DU node. In addition, CU can be divided into a network device in the access network RAN, and CU can also be divided into a network device in the core network CN, which is not limited 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, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0170] like Figure 5 As shown, the O-RAN network architecture mainly includes a service management and orchestration module (service management and orchestration, SMO), a non-real time RAN intelligent controller module (non-real time RAN intelligent controller, Non-RT RIC), a near real-time wireless intelligent controller module (near-real time RAN intelligent controller, Near-RT RIC), an open centralized unit (O-RAN central unit, O-CU) and an open distributed unit (O-RAN 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 of 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 RAN domain of the radio access network. 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, and the terminals perform load transfer between devices.

[0173] A terminal may also be called user equipment (UE), an access terminal, a subscriber unit (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 handset, a laptop computer, a machine type communication (MTC) terminal, a computer with a 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, 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 a terminal function, and a wireless terminal in a smart city. unit, RSU), etc., flying equipment (e.g., intelligent robot, hot air balloon, drone, airplane), etc. The terminal of the present application may also be a vehicle-mounted module, vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip or vehicle-mounted unit built into the 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 the present application do not limit the device form of the terminal. The device for realizing the function of the terminal can be a terminal; it can also be a device that can support the terminal to realize the function, such as a chip system. The device can be installed in the terminal, or used in combination with the terminal. In the embodiments of the present application, the chip system can be composed of chips, or it can include chips and other discrete devices.

[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 use of green energy of the first network element is analyzed through the green energy indicator, and indication information is sent, and the indication information is used to instruct the first network element to perform load transfer based on green energy between network elements based on the value of 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 equipment. In addition, the load transfer based on green energy in the embodiments of the present application can also be a load adjustment based on green energy. The balance between green energy supply and energy consumption can be achieved through load transfer or load adjustment based on green energy.

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

[0177] The following will be combined Figure 6-Figure 10 The interaction process between each network element / device in the above communication system is specifically introduced through a method embodiment. The method for load transfer based on green energy provided in the embodiment of the present application can be applied to the above communication system, and is specifically applied to the various scenarios / processes mentioned in the above communication system, which are specifically introduced below.

[0178] Figure 6 A flow chart of a 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 communication system, and mainly involves the interaction between the first management function and the first network element.

[0179] like Figure 6 As shown, 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 use of green energy. The source of the green energy indicator may be carried in a service profile in a service level agreement (SLA). If it is a slice-level or entire network-level indicator requirement, the green energy indicator requirement 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 after secondary processing and calculation of the green energy usage information collected from the site energy management system, such as carbon emission efficiency.

[0183] Optionally, 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. The above green energy indicators can accurately analyze the use of green energy. Of course, the corresponding indicators can be selected according to the specific situation, and there is no limitation on this. For example, when the first network element is a base station and the base station is subjected to load transfer based on the green energy indicator, 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 the value of at least one green energy indicator.

[0186] S603: The first network element receives 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 load transfer based on green energy between network elements based on the indication 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 is not limited. 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 the first network element to transfer the load based on green energy with the second network element of the same functional type, and instructs the first load amount to be transferred 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 between the first network element and the second network element by itself, instead of the first network element determining it by itself, so that the overhead on the device side can be reduced.

[0193] Optionally, the load transfer method based on green energy may further include: before sending the indication information to the first network element, obtaining energy usage of each of multiple network elements related to the first network element. According to 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 of the first network element.

[0194] 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. Based on the energy usage, the second network element that can transfer the load with the first network element is selected from the multiple network elements to achieve the load transfer of the first network element based on green energy. For example, the SON management function identifies multiple network elements related to network element 1, obtains the energy usage of each of the multiple network elements, and selects network element 2 that can transfer the load with network element 1 from the multiple network elements.

[0195] Among them, 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 value or the minimum value in the threshold range of the respective green energy indicators. The load transfer of the second network element to the first network element is: 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 can be understood that the above-mentioned matching can be that 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 is a negative value, and 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 is a positive value. 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 is a positive value, and 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 is a negative value. It can also include two differences being equal or close. In this way, the second network element that can transfer the load with the first network element can be accurately screened out.

[0197] Among them, the green energy index 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, determine whether there is a base station 2 with a carbon emission efficiency / carbon intensity measurement value lower than the minimum value in the threshold range of carbon emission efficiency / carbon intensity among the multiple adjacent base stations. 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 letting the carbon emission efficiency / carbon intensity measurement value of base station 2 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] In addition, the energy usage of each of the multiple network elements can also 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 is: the difference between the green energy supply and energy consumption of the first network element matches the difference between the green energy supply and energy consumption of the second network element.

[0199] It can be understood that the second network element is screened by the difference between the green energy supply and energy consumption of each of the multiple network elements. The above-mentioned matching can be that the difference between the green energy supply and energy consumption of the first network element is a negative value, and the difference between the green energy supply and energy consumption of the second network element is a positive value, 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. Or, the difference between the green energy supply and energy consumption of the first network element is a positive value, and the difference between the green energy supply and energy consumption of the second network element is a negative value, 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. It can also include two differences that are equal or close. In this way, the second network element that can transfer the load with the first network element can be accurately screened.

[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 the multiple base stations. If the green energy supply of base station 1 is lower than the energy consumption, determine whether there is a base station 2 with a green energy supply higher than the energy consumption among the multiple adjacent base stations. If 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 for transferring part of the load of base station 1 to base station 2.

[0201] In addition, if there are multiple second network elements that can transfer load with the first network element, part of the load of the first network element will be distributed and transferred to multiple second network elements. For example, if it is found that the green energy supply of multiple base stations 2 is higher than the energy consumption, the SON management function can distribute and transfer part of the load of base station 1 to multiple other base stations 2 under the premise of considering the impact of adjusting the network load on the network service quality.

[0202] For another example, if the green energy supply of base station 1 is higher than the energy consumption, it is determined whether there is a base station 2 among multiple neighboring base stations whose green energy supply is lower than the energy consumption. When there is a base station 2 among the multiple neighboring base stations that meets the requirements, the SON management function sends 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] In addition, if there are multiple second network elements that can transfer load with the first network element, part of the load of the first network element will be dispersed and transferred to multiple second network elements. For example, if it is found that the green energy supply of multiple base stations 2 is lower than the energy consumption, the SON management function can transfer part of the load of multiple base stations 2 to base station 1 under the premise of considering the impact of network service quality caused by adjusting the network load. In this way, by adjusting the load between adjacent network elements, a balance between energy consumption and green energy supply can be achieved, such as increasing the load of base stations with sufficient green energy supply, thereby achieving carbon efficiency optimization.

[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 can be understood that the load balancing optimization function can be an LBO function, and the LBO function can be a load balancing optimization execution entity, which is used for self-optimization of 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 can uniquely identify the LBO function. The first management function directly sends an indicative configuration policy to the LBO function deployed in the first network element, without specifying the destination of the load transfer, but the LBO function determines it by itself, and 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 load transfer based on green energy 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 needs to 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 may be a configuration management function, and the load balancing optimization function attributes may 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 modify the LBO function attribute to the configuration management function. The request may include the LBO function identifier and green energy reference indication information, and may also include the value range of the green energy index. The configuration management function modifies the LBO function attribute (non-standard interface), and changes the value of the green energy reference indication information from "0" to "1", and the LBO function performs load balancing optimization based on green energy. That is, when deciding on the access of a terminal device to a cell or base station, the impact on the green energy index of the cell or base station after the switch will be considered.

[0209] In another possible design, the indication information is used to instruct the green energy balancing function to perform load transfer based on green energy between network elements, and 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, 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 green energy indicators.

[0210] It can be understood that the green energy balancing function can be used as a newly added management object to optimize the balance between green energy supply and network element energy consumption. The identifier of the green energy balancing function can be an identifier such as a letter, number or symbol that can uniquely identify 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, without specifying the destination of the load transfer. Instead, the green energy balancing function makes its own judgment and instructs the first network element to consider the green energy index when making load transfer adjustments, that is, 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 the green energy balancing function attribute, and 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 newly 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 modify the green energy balancing function attribute to the configuration management function. The request may include the green energy balancing function identifier and green energy reference indication information, and may also include the value range of the green energy index. The configuration management function modifies the green energy balancing function attribute. If the value of the green energy reference indication information is changed from "0" to "1", the green energy balancing function performs load balancing optimization based on green energy. That is, when deciding whether the terminal device accesses a cell or base station, the impact on the green energy index of the cell or base station after the switch will be considered.

[0213] Optionally, the indication information may further include a threshold range of at least one green energy indicator. The threshold range of the green energy indicator is used to clarify the standard value of green energy measurement or statistics. The measured value of the green energy indicator is analyzed by the threshold range of at least one green energy indicator to determine whether the measured value of the green energy indicator meets the requirement, for example, the difference between the green energy supply and the energy consumption of the base station is analyzed to determine whether the balance of green energy is 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, indication 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 S502, the green energy-based load transfer method 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 value of carbon emission efficiency. If the value of the first green energy indicator among the at least one green energy indicator is not within the threshold range, it means that the value of the first green energy indicator is lower or higher, so it is necessary to send indication information to trigger load transfer based on green energy.

[0217] For example, the first management function analyzes the value of the green energy index and determines the indication information. When the measured value of the carbon emission efficiency of network element 1 is not within the threshold range, the first management function determines network element 1 as a network element object that needs to make green energy balance adjustment and determines the adjustment strategy, that is, 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 may be a configuration management function, which may be used to forward 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, so that the first network element may accurately execute the indication information.

[0220] For example, the first management function sends indication information to the configuration management function. After the first management function determines the indication information (load adjustment strategy), it sends the identifier of the network element 1 from which the load needs to be moved out (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 indication information to network element 1, and can also send indication information to network element 2 that can transfer load with 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; obtaining the value of at least one green energy indicator of the first network element may include: obtaining a flow 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 according to the flow indicator of the terminal device.

[0224] It can be understood that the near real-time wireless intelligent controller module monitors the green energy indicators of the first base station and the neighboring base stations, and monitors the flow indicators of the terminal devices served by the base station, and the flow indicators can be, for example, the proportion of the terminal device flow in the total flow of the base station. In the case where the first management function is the near real-time wireless intelligent controller module, the indication information can include a flow transfer strategy.

[0225] Optionally, at least one green energy indicator value of the first base station is obtained. It is determined whether a green energy indicator value among the at least one green energy indicator value is not within 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 in the value of at least one green energy indicator is not within the threshold range, the difference between green energy supply and 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 of the service object under 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 connected to 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 device connected to base station 1 (or CU1) is too high, that is, exceeds the threshold range, the terminal device connected to base station 1 is 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 device 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 device connected to base station 2 (or other CU) is 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] The embodiment of the present application provides another load transfer method based on green energy, which is applied to the third management function, including: obtaining a threshold range of a green energy indicator. 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 a threshold range of the green energy indicator.

[0232] It can be understood 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, that is, the green energy indicator requirement. The threshold range of the green energy indicator can be specified by the cross-domain management system itself, or it 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, and request the green energy balancing service from the first management function through the third management function, and carry the identifier of the first network element and the threshold range of the green energy indicator, and then the first management function guarantees 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 the 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 index, and sends a request for a green energy-based traffic transfer strategy to the near real-time wireless intelligent controller module, and the request may include the identifier of base station 1, the threshold range of the green energy index, and the green energy reference indication information. The green energy-based traffic transfer strategy here has the same function as the above-mentioned green energy balanced self-organizing service. The purpose of the traffic transfer strategy is to intelligently control the 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 the threshold range of the green energy indicator, and determines whether to trigger the green energy balancing function based on the comparison result. Whether to trigger the green energy balancing function is determined according to the energy consumption of the site, such as triggering the green energy balancing function when the green energy supply is seriously greater than or less than the energy consumption.

[0236] In addition, the first network element may be a network element where the green energy supply and actual energy consumption are seriously unbalanced. If the green energy management function does not screen out the first network element where the green energy supply and actual energy consumption are seriously unbalanced, the identifier of the first network element refers to the identifier of the network element where the green energy management function hopes to achieve green energy self-balancing, and whether the balance is left to the first management function for monitoring and management.

[0237] The embodiment of the present application provides another load transfer method based on green energy, which is applied to a fourth management function, including: receiving a measurement request for a value of a green energy indicator of a first network element sent by a first management function. Based on the measurement request, sending the value of the green energy indicator of the first network element to the first management function.

[0238] It can be understood that the fourth management function can be a performance management function, and the measurement request can include the identifier of the first network element. The measurement request for the value of the green energy indicator of the first network element sent by the first management function is received through 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 can be directly measured or calculated after measurement.

[0239] For example, the SON management function sends a request to the performance management function to measure the value of the green energy indicator 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. Then the performance management function 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] Combination of the above Figure 6 The overall process of the load transfer method based on green energy provided by the embodiment of the present application is described below. Figure 7-10 The specific process of the green energy-based load transfer method provided in the embodiments of the present application in various scenarios is specifically introduced.

[0243] Scenario 1:

[0244] Figure 7 The process diagram of the load transfer method based on green energy provided in this embodiment is as follows: Figure 2 . 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 devices, thereby improving the carbon emission efficiency of communication equipment.

[0245] Specifically, Figure 7As shown, 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 can be understood 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 trigger a green energy balancing self-organizing service to the network autonomous management function.

[0250] The network autonomous management function may be a SON management function, and the request for triggering the green energy balancing self-organizing service may include the identifier of the network element 1 and the threshold range of the green energy indicator, and the green energy balancing self-organizing service is a load balancing service based on green energy. Among them, the 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 for measuring the value of the green energy indicator of network element 1 to the performance management function.

[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 , and 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 index 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 index to the network autonomous management function.

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

[0256] For example, when the measured value of the carbon emission efficiency of network element 1 is monitored to be out of the threshold range, the network autonomous management function determines network element 1 as a network element object that requires green energy balance adjustment and determines the adjustment strategy, i.e., the indication 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 strategy), it sends the identifier of the network element 1 from which the load needs to be moved out (source network element identifier), the identifier of the network element 2 to which the load is moved in (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 the network element 1, and can also send the indication information to the network element 2 that can transfer the load with the network element 1. The configuration management function configures the received strategy to the relevant network element 1 and network element 2 (this interface is not a standard interface).

[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 S703 - S708 may occur cyclically to reflect network autonomy.

[0263] Scenario 2:

[0264] Figure 8 The process diagram of the load transfer method based on green energy provided in this embodiment is as follows: Figure 3 . 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 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 according to its own actual situation and perform load balancing based on green energy indicators more dynamically and flexibly.

[0265] Specifically, Figure 8 As shown, 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 trigger a green energy balancing self-organizing service to the network autonomous management function.

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

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

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

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

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

[0273] The request for modifying the attributes of the load balancing optimization function may include the identifier of the load balancing optimization function and the green energy reference indication information, and may also include the 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 use 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 the green energy reference information can be expressed as "yes / no", "on / off", or "0 / 1", etc., which is not limited here. For example, when the value of the green energy reference information is "yes", "on", or "1", it means that the use of green energy needs to be included in the reference input of load balancing optimization. Load balancing optimization based on green energy means that when deciding on the access of a terminal device to a cell or base station, the impact of the switch on the green energy index of the cell or base station will be considered.

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

[0279] Scenario 3:

[0280] Fig. 9 The process diagram of the load transfer method based on green energy provided in this embodiment is as follows: Figure 4. 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 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 according to its own actual situation and perform load transfer based on green energy indicators more dynamically and flexibly.

[0281] Specifically, Fig. 9 As shown, 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 trigger a green energy balancing self-organizing service to the network autonomous management function.

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

[0285] S904, the performance management function returns the value of the green energy index to the network autonomous management function.

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

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

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

[0289] The request for modifying the green energy balancing function attribute may include the green energy balancing function identifier 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 attribute.

[0292] S908: If the green energy reference information indicates that the use 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 the green energy reference information can be expressed as "yes / no", "on / off", or "0 / 1", etc., which is not limited here. For example, when the value of the green energy reference information is "yes", "on", or "1", it means that the use of green energy needs to be included in the reference input of load balancing optimization. Load balancing optimization based on green energy means that when deciding on the access of a terminal device to a cell or base station, the impact of the switch on the green energy index of the cell or base station will be considered.

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

[0295] Scenario 4:

[0296] Fig.10 The process diagram of the load transfer method based on green energy provided in this embodiment is as follows: Figure 5 . 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 usage of green energy of the first base station through green energy indicators, and instructs the first base station to perform load balancing based on green energy between network elements, which can intelligently control the traffic between multiple cells, thereby improving the user experience.

[0297] Specifically, Fig.10 As shown, 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.

Since the proportion of terminal device traffic in the total base station traffic is equal to the proportion of terminal device green energy consumption in the total green energy consumption of the base station, the green energy consumption at the terminal device level can be derived.
