[0002] Pre-caching data content during off-peak hours is an effective way to alleviate network congestion during peak hours. User demand is predictable, and memory hardware in wireless devices and base stations is more cost-effective than bandwidth. Caching systems adaptively adjust caching and multicast strategies based on user requests to meet end-user needs, saving costs and reducing latency.

[0070] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0071] Pre-caching data content during off-peak hours is an effective way to alleviate network congestion during peak hours. User demand is predictable, and memory hardware in wireless devices and base stations is more cost-effective than bandwidth. Caching systems adaptively adjust caching and multicast strategies based on user requests to meet end-user needs, saving costs and reducing latency. Storing data content close to end users is an effective way to implement edge caching technology. Caching technologies generally fall into two categories: active caching deployed at the base station and caching deployed at the user end.

[0072] In the related art, a caching method based on base station clustering actively stores content in the base station before a request arrives, which can reduce the traffic on the backhaul link, thereby alleviating the traffic load in the cellular system and improving system performance.

[0073] In the related art, see Figure 1 As shown in the figure, the implementation of the base station clustering-based caching method is as follows: historical requests from user terminals served by each base station in a dense base station network are collected and analyzed. Based on these historical requests, base stations are clustered, and users within each cluster serve users with similar interests. Collaborative filtering, a technique used in recommendation systems, is then combined to make decisions about the cache content of each base station. Clustering-based collaborative filtering effectively improves the algorithm's scalability and data sparsity. Combining the local popularity of content with the TOPN collaborative system improves the base station's cache hit rate, effectively resolving the conflict between the limited cache capacity of base stations and the ever-increasing amount of data, thereby improving user satisfaction and network backhaul load.

[0074] However, the technical methods for base station energy saving in related technologies do not take into account the scenarios of new energy, and the technical solutions for the coordinated storage of new energy and the absorption of communication network services are still relatively lacking.

[0075] Fifth-generation mobile communication technology (5G) features low latency and large bandwidth, but this also significantly increases base station power consumption and carbon emissions. Energy conservation and carbon reduction are a key focus for 5G communications. New energy sources such as wind, solar, and hydropower are effective ways to decarbonize base stations, but they are inherently sporadic and uncertain. Synergistic models between new energy sources and base stations are also being explored. Currently, in new energy source-load-storage synergy technologies, the integration of new energy consumption and base station operating modes is not yet close enough.

[0076] To address the call for energy conservation and low carbon emissions, the deployment and construction of base stations based on renewable energy sources such as photovoltaics and wind power is rapidly improving. However, the power generation capacity of renewable energy sources is easily affected by factors such as sunlight intensity and wind speed, resulting in uncertainty in both time and power generation. Battery storage systems experience wear and tear, and their cost increases with the amount of storage capacity. New energy storage batteries help to reduce peak power consumption during daily base station operations. However, during periods of peak renewable energy production, battery capacity may be insufficient. Blindly increasing battery capacity is not a viable solution, and further exploration is needed to determine how renewable energy storage and base station systems can work together.

[0077] This application proposes a solution to consume new energy by pushing cache services to terminals through base stations.

[0078] The embodiment of the present application provides a caching method based on new energy consumption, which is applied to management equipment, such as Figure 2 As shown, the method includes:

[0079] Step 101: Obtain first information, where the first information indicates service characteristics of historical cache services of a network device.

[0080] In actual application, the management device can be set up on any side of the core network, power grid, or base station. The first information is obtained based on historical cache services. The "obtain" in each step of this application can be understood as "determine", "generate", "get / receive", and "determine".

[0081] In some embodiments, the first information includes: an association parameter (eg, θ represents the association parameter) between the relevant information of the user terminal and the relevant information of the network device included in the historical cache service.

[0082] Step 102: Obtain second information and third information, where the second information includes relevant information of the user terminal, and the third information includes relevant information of the network device.

[0083] In some embodiments, the second information includes: the number of connections of user terminals connected to the network device (for example, Uk represents the number of connections of the current user of base station K); the average distance of user terminals connected to the network device (for example, Udis represents the average distance of connected users of base station K).

[0084] In some embodiments, the third information includes: channel condition characteristics of the network device (e.g., Chk represents the channel condition characteristics of base station K); and transmission path loss of the network device (e.g., Lk represents the transmission path loss of the base station), where K is a positive integer.

[0085] Step 103: Allocate new energy resources to network devices based on the first information, the second information, and the third information.

[0086] In actual application, the first information (including the above-mentioned associated parameters), the second information (including relevant information of the user terminal) and the third information (relevant information of the network device) are combined to allocate new energy resources to the network device to ensure the optimal energy consumption of the base station push cache service.

[0087] In actual application, new energy resources include but are not limited to new energy resources generated by wind power generation and photovoltaic power generation.

[0088] In some embodiments, step 103 allocates the new energy resource to the network device based on the first information, the second information, and the third information, which can be achieved by the following steps:

[0089] determining a first resource consumption of the network device based on the first information, the second information, and the third information;

[0090] Determining a first allocation ratio of the network device based on the first resource consumption;

[0091] The new energy resource is allocated to the network device based on the first allocation ratio and the total amount of the new energy resource.

[0092] In actual application, the first resource consumption includes but is not limited to the estimated power consumption (Yk represents the estimated power consumption of base station K). Ek represents the power allocated by base station K. Furthermore, the management device can convert the estimated power consumption into an allocation ratio and allocate it to the network devices (e.g., base stations) according to the required power ratio.

[0093] When renewable energy storage capacity is insufficient, this application distributes the stored power to K nearby base stations. During periods of relatively idle network resources, this application pre-caches services, increasing the base station's transmission of services to user equipment (UE), consuming the stored power, reducing power abandonment, and renewing the storage capacity. By combining service caching with renewable energy, daily base station services are pre-transmitted, reducing carbon emissions and lowering energy consumption.

[0094] In actual applications, by analyzing the historical power consumption of base station push cache services, we can estimate the power consumption of each base station's push cache services in the current state, thereby optimizing the allocation ratio of renewable energy power. When evaluating the power Yk that the push cache services of K base stations near the battery may consume, based on the influence of factors such as the number of users and distance on the base station push cache, the estimated power consumption of base station K can be calculated using the following formula:

[0095]

[0096] Among them, Uk represents the number of current user connections of base station K; Udis represents the average distance of connected users of base station K; Chk represents the channel condition characteristics of base station K; Lk represents the base station transmission path loss; θ represents the parameter obtained based on the historical cache data of the base station.

[0097] In practical applications, the estimated power consumption Y of each base station obtained above is used to perform a conversion so that the power consumption ratio of the K base stations sums to 1. The power consumption probability of the K base stations near the battery can be represented by a vector: P = {P1, P2, ..., PK}. The total amount of incoming renewable energy power resources is E. Based on the base station power consumption ratio, the incoming renewable energy power is distributed to the K nearby base stations, which can be expressed by the following formula:

[0098]

[0099] Wherein, 1≤i≤k, i is a positive integer.

[0100] This application allocates renewable energy power to K neighboring base stations, finding the optimal power allocation ratio based on the current base station status. After base station k allocates power Ek, it uses the allocated renewable energy power to send cached data to user terminals through the cache service scheduling mechanism.

[0101] This application can reasonably allocate new energy electricity to K surrounding base stations. According to the current status of the base stations near the new energy storage batteries, it calculates the possible power consumption of each base station's push cache service. When the total new energy electricity is known, the proportion of allocated new energy electricity to the K base stations is calculated to maximize the energy efficiency of the base station cache service.

[0102] The embodiment of the present application provides a caching method based on new energy consumption, which is applied to network equipment, such as Figure 3 As shown, the method includes:

[0103] Step 201: Receive new energy resources allocated by a management device.

[0104] In actual application, the network device can be an evolved base station (eNB or eNodeB) in the Long Term Evolution (LTE) system, or a next-generation radio access network (NG RAN) device, or a base station (gNB) in the NR system, or a wireless controller in the cloud radio access network (CRAN), or the network device can be a relay station, access point, vehicle-mounted device, wearable device, hub, switch, bridge, router, or network equipment in the future evolved public land mobile network (PLMN), etc.

[0105] Step 202: Send a first message to the user terminal, where the first message is used to notify that the allocated new energy resources have arrived at the network device.

[0106] In a feasible scenario, taking the interaction between the base station gNB and UE as an example, the caching method based on new energy consumption is explained, combined with Figure 4 As shown in the figure, the gNB sends the Master Information Block (MIB) to the UE, the gNB sends the System Information Block Type 1 (SIB1) to the UE, the UE sends a System Information Request to the gNB, and the gNB sends a (Requested) System Information Message to the UE. Through these interactions, when new energy arrives, the gNB switches to new energy mode. Simultaneously, the gNB sends a notification to the connected UE indicating that new energy arrival mode is currently in effect.

[0107] Step 203: Use the allocated new energy resources to send the buffered data to the user terminal, or do not use the allocated new energy resources to send the buffered data to the user terminal.

[0108] In practice, upon receiving a notification from the base station, the UE may choose not to respond or decide whether to exit the new energy mode based on the UE's current usage status. The gNB may receive requests from some UEs to exit the new energy arrival mode and will switch the corresponding UEs back to the normal mode. Furthermore, the gNB does not use the allocated new energy resources to send buffered data to the user terminal, i.e., it sends buffered data in the normal mode.

[0109] Other UEs continue to maintain the new energy arrival mode, and the gNB uses the allocated new energy resources to send buffered data to other UEs until the new energy power is consumed.

[0110] In some embodiments, using the allocated new energy resources to send the cached data to the user terminal in step 203 may be achieved by the following steps:

[0111] Based on the fourth information and fifth information in the network device, the allocated new energy resources are used to send cached data to the user terminal, the fourth information indicates the distance ranking of different user terminals from the network device, and the fifth information indicates the service ranking of different services.

[0112] In actual application, distance sorting includes but is not limited to ascending order, such as establishing a user terminal list U = {u1, u2, ..., un}, and arranging them in ascending order according to the distance L between the current base station and the user terminal. When the network device of this application sends cached data to the user terminal, it gives priority to transmitting the data to the terminal at a close distance L. In this way, the closer the distance between the user terminal and the base station, the less power the base station consumes in transmitting data to the user terminal, and the more cached data can be transmitted to more user terminals, maximizing user service coverage. Among them, the close distance L refers to the distance within the distance threshold range. The distance threshold range can be set based on actual needs and is not specified in this application.

[0113] In practical applications, service sorting includes, but is not limited to, ascending order. A service index list B = {b1, b2, ..., bn} is established. Each service in the list includes two fields: bi = {idi, hoti}, where id is the service identification number and hot represents the current popularity of the service. This means that the number of service visits to K base stations over the past ten days, including but not limited to popular video, audio, and other service data, is counted. The service index list is sorted in descending order by hot value.

[0114] In one feasible scenario, based on the fourth and fifth information from the base station, when using allocated new energy resources to send cached data to user terminals, the base station pushes popular services to connected user terminals through a service scheduling mechanism. After allocating power Ek, base station k prioritizes services to nearby user terminals as it consumes the allocated power, ensuring maximum cached service user coverage. Simultaneously, it pushes selected, popular cached services to user terminals, increasing the hit rate of cached services for terminal users and alleviating network pressure during peak traffic periods.

[0115] This application proposal designs a base station to use the power provided by new energy to push cache service scheduling mechanism to the terminal, calculate the current connected user terminal and cache service priority respectively, and consider the base station transmission distance factor to maximize the coverage of cache service users.

[0116] In some embodiments, based on the fourth information and the fifth information in the network device, using the allocated new energy resources to send the cached data to the user terminal can be achieved by the following steps:

[0117] First, a user terminal is selected based on the fourth information, and based on the fifth information, it is determined that a cached service corresponding to existing cached data of the user terminal meets a first condition, and the cache space of the user terminal is refreshed, where the first condition indicates that the existing cached service is a service to be deleted;

[0118] Secondly, receiving sixth information sent by the user terminal, where the sixth information indicates available memory of the cache space of the user terminal;

[0119] Finally, based on the available memory, the allocated new energy resources are used to send the buffered data to the user terminal.

[0120] In actual application, the network device refreshes the cache space of the user terminal. After the new energy arrives, the cache service scheduling mechanism is used to start the cache service scheduling.

[0121] In some embodiments, the first condition includes one or more of the following:

[0122] The cached business corresponding to the existing cached data is not in the business sorting;

[0123] The cache service indicator corresponding to the existing cached data is less than the indicator threshold.

[0124] In actual application, each UE has a cache space for receiving cache services, and the memory size of the cache space is M.

[0125] In actual application, the indicator threshold includes but is not limited to the minimum heat threshold (hot_min), where hot_min can be determined based on the actual business scenario, and this application does not make any specific restrictions.

[0126] In some embodiments, based on available memory, using allocated new energy resources to send cached data to a user terminal includes:

[0127] When the available memory is less than the memory threshold, the allocated new energy resources are used to sequentially send the cached data corresponding to the service order to the user terminal until the available memory exceeds the memory threshold;

[0128] Here, when the available memory is less than the memory threshold, it means that the terminal cache space m is not full, and the allocated new energy resources are used to sequentially send cache data corresponding to the service sorting to the user terminal until the available memory is greater than the memory threshold.

[0129] When the available memory is greater than or equal to the memory threshold, the allocated new energy resources are used to send the corresponding buffered data to the next user terminal of the user terminal corresponding to the distance ranking.

[0130] Here, when the available memory is greater than or equal to the memory threshold, it indicates that the cache space is full, and the push process of the cache service for the current user ends. Then, according to the order of the user terminal list U, the cache service is pushed to the next user terminal uj+1 until the allocated new energy power is consumed or the terminal list ends.

[0131] This application provides a cache service scheduling mechanism for a base station in a new energy scenario, which maximizes the cache service user coverage rate while improving the user cache service hit rate.

[0132] In an achievable scenario, as shown in Figure 5 After the new energy arrives, the cache service scheduling mechanism is used to start the cache service scheduling, including the following steps:

[0133] Step 301: Select the first UE in the list U.

[0134] Select the user uj according to the order of the user terminal list U, refresh the cache space of the current user terminal. If the existing cache service bi is not in the service list B, or the popularity hoti of the existing cache service bi is less than hot_min, then delete the service cache.

[0135] Step 302: Refresh the UE memory.

[0136] Step 303: Check if there is free memory. If yes, execute Step 304; otherwise, execute Step 305.

[0137] Step 304: Send the data in the cache service list B.

[0138] After refreshing the cache space of the user terminal, if the terminal cache space m is not full, that is, m < M. Then, according to the order of the service index list B, the cache service bi is sent sequentially. If the terminal has already cached the current service bi, then skip this service until the cache space is full, and the push process of the cache service for the current user ends.

[0139] After refreshing the cache space of the user terminal, if there is no free memory in the cache space, then end the push process of the cache service for the current user.

[0140] Step 305: Check if the power is exhausted. If not, execute Step 306; if yes, end the process.

[0141] Step 306: Select the next UE in the list U.

[0142] According to the order of the user terminal list U, the cache service is pushed to the next user terminal uj+1 until the allocated new energy power is consumed or the terminal list ends.

[0143] This application combines the elastic scaling of new energy storage batteries, improves the implementation method of rationally allocating stored new energy to base stations, maximizes base station energy efficiency, and achieves the goal of reducing carbon emissions and energy consumption. This application adds a cache service scheduling mechanism from base stations to user terminals. The proposed base station cache service scheduling mechanism alleviates network pressure during peak service periods by pre-caching user terminals.

[0144] The embodiment of the present application provides a caching method based on new energy consumption, which is applied to user terminals, such as Figure 6 As shown, the method includes:

[0145] Step 401: Receive a first message sent by a network device, where the first message is used to notify that allocated new energy resources have arrived at the network device.

[0146] In actual applications, the user terminal may be user equipment (UE), such as a mobile phone, a computer, and may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a smart phone, a personal digital assistant (PDA), a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, a wireless modem card, customer premises equipment (CPE) and / or other devices used to communicate on a wireless system.

[0147] Step 402: Receive buffered data sent by the network device using the allocated new energy resources, or receive buffered data sent by the network device without using the allocated new energy resources.

[0148] The terminal receives a notification from the base station indicating that it is in the new energy arrival mode. The terminal decides whether to exit the new energy mode. That is, the terminal can receive cached data in the new energy mode or in the normal mode.

[0149] In some embodiments, before step 402 of receiving the cached data sent by the network device using the allocated new energy resources, the method further includes:

[0150] Sixth information is sent to the network device, where the sixth information indicates available memory in the cache space of the user terminal.

[0151] In actual application, each UE has a cache space for receiving cached services, and the cache space memory size is M. After refreshing the memory, the terminal sends sixth information to the network device to report available memory.

[0152] Based on the above, this application proposal proposes a caching solution based on the absorption of new energy. Based on the estimated allocation ratio, new energy is allocated to base stations near the battery storage to maximize base station energy efficiency. Furthermore, a base station cache service scheduling mechanism is proposed to maximize cache service user coverage. The base station pushes cache services to the terminal through the cache service scheduling mechanism to absorb the power provided by new energy, which is applied to scenarios where base station service energy consumption is scalable. The user terminal caches services in advance, which can also alleviate network pressure during peak service periods.
