[0002] With the rapid development of wireless communication technology, operators have deployed a large number of base stations to increase the overall service performance of cellular networks. In a cellular network, base stations cover multiple cells, and a large number of user terminal devices connect to suitable cells to meet users' needs for high-speed data services.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] It should be further understood that the terms “comprising” or “including” indicate the presence of features, steps, operations, elements, components, items, kinds, and / or groups, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups.

Exceptions to this definition occur only when combinations of elements, functions, steps, or operations are inherently mutually exclusive in some way.

[0055] To meet users' demand for high-speed data services, operators have deployed a large number of base stations, which can cover multiple cells. The communication system can select a suitable cell from these cells to connect with the user's terminal equipment.

[0056] In existing communication systems, when a user terminal device receives a connection request, it selects a cell with lower load or a cell with a higher RSRP (Signal-to-Noise Ratio) between the terminal device and the cell to connect to the user terminal device. However, the cell selected based on RSRP may have a lower signal-to-noise ratio, requiring more energy to complete the user service, resulting in resource waste and increased costs for the operator.

[0057] To address the aforementioned issues, this application proposes a cell connection method, apparatus, base station, and storage medium. While considering RSRP (Resource Retention Rate), it also comprehensively considers the energy required for each cell to complete user service requests, enabling the cell ultimately determined to connect to the user terminal equipment to transmit user services at high speeds while reducing energy consumption and saving operator costs.

[0058] The technical solutions of this application will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0059] Figure 1 A schematic diagram of a cell connection scenario provided by an embodiment of this application is shown. For example... Figure 1 As shown, the base station covers multiple cells such as cell 1, cell 2, cell 3, and so on. The user terminal equipment is within the coverage area of ​​these cells, meaning that these cells can all meet the service transmission requirements of the user terminal equipment. At this time, the communication network will select a suitable cell from these cells to connect to the user terminal equipment.

[0060] In this application, a base station is used as the execution entity to perform the cell connection method of the following embodiments. Specifically, the execution entity can be a hardware device of the base station, or a software application implementing the following embodiments in the base station, or a computer-readable storage medium installed with the software application implementing the following embodiments, or code implementing the software application.

[0061] Figure 2 A flowchart illustrating a cell connection method according to an embodiment of this application is shown. Figure 2 As shown, with the base station as the executing entity, the method in this embodiment may include the following steps:

[0062] S201. Receive a connection request from a user terminal device, the connection request including a first service request.

[0063] The first business request can be a business with high real-time requirements, such as watching videos, making voice calls, or making video calls, or a business with low real-time requirements, such as sending messages.

[0064] S202. Based on the connection request, determine the first cell cluster where the user terminal device can reside.

[0065] The connection request may also include the location of the user terminal device, which determines the multiple cells it can connect to. These cells must be able to efficiently complete the first service request.

[0066] S203. Determine the first energy consumption required for each of the multiple cells in the first cell cluster to complete the first service request.

[0067] For example, we can obtain the connection information between the aforementioned multiple cells and user terminal devices during the past time period T. From this, we can determine the total number Q resource blocks in cell n. n Utilization rate L n The number of resource blocks K used for signaling transmission in cell n n And the number of resource blocks P used by cell n to complete user services. n The following relationship exists:

[0068] P n =Q n *L n -K n

[0069] The energy consumed by cell n during the past time period T is denoted as E. n Then the energy consumed per unit resource block in cell n is

[0070]

[0071] Each cell connects to M user terminal devices, and the number of resource blocks allocated to each user terminal device for completing services is denoted as U. m The traffic transmitted for each service resource block is denoted as T. m Therefore, it can be known that the traffic that a unit resource block of cell n can transmit during the past time period T is denoted as V. n ,but

[0072]

[0073] When a business request is received, estimate the traffic F that the business request will generate. m Then the energy required for cell n to complete this service request is

[0074]

[0075] Among these, the traffic that business requests will generate can be estimated using a business model.

[0076] For example, a business model can be built based on data such as the traffic generated by a user's access to various software at different times within a past time period t.

[0077] Time period Accessed App The generated traffic 0：00-1：00 {APP1, APP2, ...} {100MB, 120MB, ...} 1：00-2：00 …… …… …… 22：00-23：00 {APP3, ...} {600MB, ...} 23：00-24：00 {APP4, APP5, ...} {150MB, 40MB, ...}

[0078] If a user accesses an app 50 minutes before the corresponding time period, data from that time period is used. If the user accesses the app 50 minutes after the corresponding time period, data from the next time period is used. For example, if a user accesses app 3 at 22:10, based on data collected from the past time period t, the median traffic generated by accessing app 3 during that time period is 600MB, so the estimated traffic will be 600MB. If the user accesses app 3 at 10:51 PM, then data from the time period 23:00-24:00 is used to estimate the traffic. The generated traffic data is the median of the traffic generated over the past time period t.

[0079] S204. Based on the first service request and the first energy consumption, determine the first target cell from the first cell cluster and connect it to the user terminal equipment.

[0080] In order to meet the high-speed transmission requirements of the first service request while minimizing energy consumption, it is necessary to select a cell from multiple cells that can balance service requests and energy consumption to connect to the user terminal equipment.

[0081] In the above embodiments, determining the first target cell based on the first service request can ensure that the first target cell can transmit the first service request at a high speed. Determining the first target cell based on the first energy consumption can ensure that the first target cell can reduce energy consumption when transmitting the first service request. This embodiment takes into account both the first service request and the first energy consumption, and the first target cell determined thereby can reduce energy consumption without affecting user communication.

[0082] Figure 3 A flowchart illustrating another cell connection method provided in an embodiment of this application is shown. Figure 3 As shown, the method in this embodiment may include the following steps:

[0083] S301. Receive a connection request from a user terminal device, the connection request including a first service request.

[0084] S302. According to the connection request, receive the reference signal received power RSRP between the user terminal equipment and the cells within the preset range.

[0085] All cells within the preset range can connect to user terminal equipment. The difference is that some cells have higher RSRP, which can meet the service needs of users with high real-time requirements, while some cells have lower RSRP, which can only meet the service needs of users with lower real-time requirements.

[0086] S303. Based on RSRP, determine the first cell cluster where the user terminal equipment can camp. The first cell cluster includes multiple cells whose RSRP reaches a first preset threshold.

[0087] It should be understood that only cells whose RSRP reaches the first preset threshold can meet the transmission requirements of the first service request and serve as alternative cells for connection with user terminal equipment.

[0088] S304. Determine the first energy consumption required for each of the multiple cells in the first cell cluster to complete the first service request.

[0089] S305. Based on the first service request and the first energy consumption, determine the first target cell from the first cell cluster and connect it to the user terminal equipment.

[0090] Among them, steps S301, S304 and S305 are respectively related to Figure 2 The implementation of steps S201, S203, and S204 in the embodiment is similar, and will not be repeated here.

[0091] In the above embodiments, the first cell cluster is determined according to RSRP, ensuring that the first target cell selected from the first cell cluster can transmit the first service request at a high rate. Under the premise of ensuring that user needs are met, the first target cell is finally determined according to the first energy consumption, thereby achieving an energy-saving effect based on user needs.

[0092] Based on the above embodiments, step S305 can be implemented as follows:

[0093] If the first service request is a first type of service request, then the cell with the lowest energy consumption in the first cell cluster is determined and connected to the user terminal device; if the first service request is a second type of service request, then a second cell cluster is determined in the first cell cluster, and the cell with the lowest energy consumption in the second cell cluster is determined and connected to the user terminal device. The second cell cluster includes multiple cells whose RSRP reaches a second preset threshold. The RSRP represented by the second preset threshold is higher than the RSRP represented by the first preset threshold. The real-time requirement of the first type of service request is lower than the real-time requirement of the second type of service request.

[0094] In simple terms, for services with low real-time requirements, such as sending messages, the RSRP of all cells in the first cell cluster can transmit the service at a high speed. Connecting the user terminal device to the cell with the lowest energy consumption can effectively reduce energy consumption. However, for services with high real-time requirements, such as voice calls, the cells in the first cell cluster may not meet the needs of high-speed transmission. In this case, it is necessary to select multiple cells from the first cluster whose RSRP reaches a second preset threshold to form a second cell cluster. From the second cell cluster, the cell with the lowest energy consumption is selected to connect to the user terminal device, ensuring that this cell can meet the user's needs.

[0095] In this implementation, for two types of services with different real-time requirements, the first target cell with the lowest energy consumption is determined from two cell clusters with different RSRP requirements. This ensures that the first target cell can meet the real-time requirements of the service request and has the lowest energy consumption compared to other cells in the corresponding cell cluster, thus achieving the effect of RSRP and energy consumption balance.

[0096] Based on the above embodiments, step S305 can also be implemented as follows:

[0097] If the first service request is a first type of service request, then the cell with the lowest energy consumption in the first cell cluster is determined and connected to the user terminal device; if the first service request is a second type of service request, then the cell with the highest RSRP in the first cell cluster is determined and connected to the user terminal device; wherein, the real-time requirement of the first type of service request is lower than that of the second type of service request.

[0098] Unlike the previous implementation, this implementation selects the cell with the lowest energy consumption from the first cell cluster to connect to the user terminal equipment for services with lower real-time requirements; for services with higher real-time requirements, it selects the cell with the highest RSRP from the first cell cluster to connect to the user terminal equipment. In this implementation, the first target cell is determined from the first cell cluster based on different selection criteria according to the different real-time requirements of the first service request. This prioritizes meeting user needs and only considers reducing energy consumption while ensuring high-speed service transmission, achieving resource savings without affecting user communication.

[0099] Figure 4 A flowchart illustrating yet another cell connection method provided in an embodiment of this application is shown. Figure 3 Based on the illustrated embodiment, this embodiment further includes receiving a second service request sent by a user terminal device and subsequent processing steps. For example... Figure 4 As shown, the method in this embodiment may include the following steps:

[0100] S401. Receive a connection request from a user terminal device, the connection request including a first service request.

[0101] S402. According to the connection request, receive the reference signal received power RSRP between the user terminal equipment and the cells within the preset range.

[0102] S403. Based on RSRP, determine the first cell cluster where the user terminal equipment can camp. The first cell cluster includes multiple cells whose RSRP reaches a first preset threshold.

[0103] S404. Determine the first energy consumption required for each of the multiple cells in the first cell cluster to complete the first service request.

[0104] S405. Based on the first service request and the first energy consumption, determine the first target cell from the first cell cluster and connect it to the user terminal equipment.

[0105] The above steps, and Figure 3 The implementation methods of the illustrated embodiments and specific implementations are similar and will not be described again here.

[0106] S406, Receive the second service request from the user terminal device.

[0107] The second service request is similar to the first service request; it can be a service with high real-time requirements or a service with low real-time requirements.

[0108] S407. Determine that the second service request and the first service request are of different types.

[0109] Here, "different types" refers to different real-time requirements. If the second service request is of the same type as the first service request—that is, both are service requests with low or high real-time requirements—then there is no need to switch the cell connected to the user terminal equipment. Switching to the second target cell is only necessary when the second service request is of a different type than the first service request, and the first target cell connected to the user terminal equipment cannot meet the RSRP requirements of the second service request, or when energy consumption is high. This ensures that the RSRP requirements of the second service request are met while reducing energy consumption.

[0110] S408. Determine the second energy consumption required for each of the multiple cells in the first cell cluster to complete the second service request.

[0111] This step and Figure 2 The implementation of S203 in the illustrated embodiment is similar and can be understood by referring to it; it will not be described again here.

[0112] S409. Based on the second service request and the second energy consumption, determine the second target cell from the first cell cluster and connect it to the user terminal equipment.

[0113] The second target cell needs to meet the requirements of high-speed transmission of the second service request, while the second energy consumption should not be too high, taking into account both service needs and resource conservation.

[0114] In the above embodiments, when the type of user service request changes, the second target cell is determined to be connected to the user terminal device based on the second service request and the second energy consumption, so that the second target cell can transmit the second service request at a high speed, and at the same time, the energy consumption required to transmit the second service request is less than that required by the first target cell, thereby achieving the effect of saving resources.

[0115] Based on the above embodiments, step S409 can be implemented as follows:

[0116] If the second service request is a type 1 service request, and the energy consumption of the first target cell in completing the type 1 service request is higher than a third preset threshold, then the cell with the lowest energy consumption in the first cell cluster is determined and connected to the user terminal device. If the second service request is a type 2 service request, and the energy consumption of the first target cell in completing the type 2 service request is higher than a fourth preset threshold, then a second cell cluster is determined from the first cell cluster, and the cell with the lowest energy consumption in the second cell cluster is determined and connected to the user terminal device. The second cell cluster includes multiple cells whose RSRP reaches the second preset threshold, where the RSRP represented by the second preset threshold is higher than the RSRP represented by the first preset threshold, and the real-time requirements of the type 1 service request are lower than those of the type 2 service request.

[0117] To meet the RSRP requirements of the first service request without significant energy consumption, a first target cell is selected to connect to the user terminal equipment. To meet the RSRP requirements of the second service request while minimizing energy consumption, a handover to the second target cell is necessary. However, handover also incurs energy consumption; therefore, a handover to the target cell only occurs when the energy consumption required to complete the second service request using the first target cell exceeds a preset threshold. The selection of the second target cell for different types of service requests can be combined with… Figure 3 The following is a specific implementation of the illustrated embodiment.

[0118] In this implementation, when the energy consumption required for the first target cell to complete the second service request exceeds a preset threshold, the second target cell is selected to connect to the user terminal device. This results in the second target cell consuming less energy to complete the second service request compared to the total energy consumption during the process of the first target cell completing the second service request and switching target cells, while achieving the effect of RSRP and energy consumption balancing.

[0119] Based on the above embodiments, step S409 can also be implemented as follows:

[0120] If the second service request is a type 1 service request, and the energy consumption of the first target cell in completing the type 1 service request is higher than a third preset threshold, then the cell with the lowest energy consumption in the first cell cluster is selected to connect with the user terminal equipment. If the second service request is a type 2 service request, and the energy consumption of the first target cell in completing the type 2 service request is higher than a fourth preset threshold, then the cell with the highest RSRP in the first cell cluster is selected to connect with the user terminal equipment. The real-time requirements for type 1 service requests are lower than those for type 2 service requests.

[0121] Similar to the specific implementation described above, a handover to the target cell is only required when the energy consumption required for the first target cell to complete the second service request exceeds a preset threshold. Determining the second target cell for different types of service requests can also be done in conjunction with... Figure 3 The following is a specific implementation of the illustrated embodiment.

[0122] In this implementation, the second target cell is determined from the first cell cluster based on different selection criteria according to the different real-time requirements of the second service request. Compared with the total energy consumption of the first target cell in completing the second service request and the process of switching target cells, the energy consumption of the second target cell in completing the second service request is less, thus achieving the effect of reducing energy consumption while meeting user needs.

For example, the apparatus embodiments described above are merely illustrative; for instance, the division of modules is only a logical functional division, and in actual implementation, there may be other division methods. For example, multiple modules may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the coupling or direct coupling or communication connection shown or discussed may be through some interfaces; the indirect coupling or communication connection between apparatuses or modules may be electrical, mechanical, or other forms.

[0138] The modules can be physically separate, for example, installed in different locations within a single device, installed on different devices, distributed across multiple network units, or distributed across multiple processors. Alternatively, the modules can be integrated, for example, installed in the same device, or integrated into a single codebase. The modules can exist in hardware form, software form, or a combination of both. This application can select some or all of the modules to achieve the objectives of this embodiment based on actual needs.

[0139] When the various modules are implemented as integrated software functional modules, they can be stored in a computer-readable storage medium. The aforementioned software functional modules, stored in a storage medium, include several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) or processor to execute some steps of the methods of the various embodiments of this application.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.

[0141] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
