[0002] In communication technology, the larger the bandwidth, the faster the data transmission rate. When a terminal accesses a cell managed by a network device, in order to meet the terminal's possible high-speed data transmission needs, the network transmission bandwidth between the network device and the terminal can be increased.

[0003] In the related art, the way to increase network transmission bandwidth is to perform CA (Carrier Aggregation) configuration, that is, to increase the network transmission bandwidth between the network device and the terminal by combining multiple independent carrier channels, so that the terminal can perform high-speed data transmission.

[0074] Beneficial effects of the embodiments of the present invention:

[0075] The embodiment of the present invention provides a method for configuring CA of a cell terminal, which obtains the number of terminals currently connected to the secondary cell and the current PRB (Physical Resource Block) load, calculates the final value load of the secondary cell, and adopts a corresponding CA configuration strategy for the terminal according to the comparison between the final value load and the preset CA configuration threshold. Since the number of terminals currently connected to the secondary cell and the current PRB load are considered at the same time, the final value load obtained can more realistically reflect the overall load status of the secondary cell including the cell operation load and signaling overhead. When the final value load is less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is not very large. After CA configuration is performed on the newly connected terminal, the signal perception of the newly connected terminal can be improved, and the signal perception of other terminals that have completed CA configuration based on the above-mentioned secondary cell will not be reduced. When the final value load is not less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is large. Even if the CA configuration is completed for the newly connected terminal based on the secondary cell, the signal perception of the newly connected terminal will not be improved, and the signal perception of other terminals that have completed CA configuration based on the secondary cell will decrease. Therefore, in this case, the A4 measurement event for the secondary cell is terminated for the newly connected terminal, and CA configuration for the secondary cell is not performed for the newly connected terminal. Therefore, the solution provided by the embodiment of the present invention can flexibly adopt the corresponding CA configuration strategy to perform CA configuration on the terminal according to the actual situation, so that the signal perception of the terminal can be improved after CA configuration.

[0082] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0083] In the embodiments of the present invention, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0084] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0085] In the related art, network equipment often uses the following method to process the CA configuration of newly connected terminals: for newly connected terminals, the network equipment directly sends an A4 measurement event to the terminal, and configures the secondary carrier of the secondary cell for the terminal according to the A4 measurement result reported by the terminal, that is, performs CA configuration. This method does not take into account the PRB load of the secondary cell and the number of terminals that have accessed the secondary cell. After completing the CA configuration for the newly connected terminal, the signal perception of the newly connected terminal may not be improved after the CA configuration, and the signal perception of other terminals that have previously performed CA configuration may decrease. In this way, the purpose of improving terminal signal perception through CA configuration cannot be achieved.

[0086] In order to solve the above problems, the embodiments of the present invention provide a method, an apparatus, a network device and a storage medium for configuring CA of a cell terminal, which are described in detail below.

[0087] First, a cell terminal CA configuration method provided by an embodiment of the present invention is described.

[0088] See also Figure 1 , is a flow chart of a first cell terminal CA configuration method provided in an embodiment of the present invention. The method is applied to a network device, which may be a base station. The method includes the following steps S101 to S104.

[0089] Step S101: Acquire the number of terminals currently accessing the secondary cell and the current PRB load.

[0090] Specifically, the network device uses the secondary carrier provided by the secondary cell to provide CA services for the terminal in the primary cell. After determining that the newly accessed terminal is in the primary cell, the network device first obtains the number of terminals currently accessing the secondary cell and the current PRB load of the secondary cell in order to determine whether CA configuration can be performed for the newly accessed terminal.

[0091] Step S102: Calculate the final load of the secondary cell based on the number of terminals and the current PRB load.

[0092] After obtaining the number of terminals currently accessing the secondary cell and the current PRB load, the number of terminals and the current PRB load are simultaneously included in the calculation process, and the calculation result is used as the final value load of the secondary cell. For example, the average value of the number of terminals and the current PRB load can be calculated as the final value load; the weighted average of the number of terminals and the current PRB load can also be calculated as the final value load. An appropriate specific calculation process can be set according to actual needs, and the number of terminals and the current PRB load can be used simultaneously in the calculation process.

[0093] In one embodiment of the present invention, before step S102, the following steps A and B are also included.

[0094] Step A: Based on the maximum number of terminals that can access the secondary cell, the number of terminals currently accessing the secondary cell is normalized.

[0095] In order to reduce the adverse effects of fluctuations in the size of the calculated data on the calculated terminal load, the calculated data may be normalized, and the calculated data may be converted into a uniform scale and limited within a certain range. After obtaining the number of terminals currently accessing the secondary cell, the number of terminals currently accessing the secondary cell may be normalized based on the maximum number of terminals that the secondary cell can access. Specifically, the number of terminals currently accessing the secondary cell may be divided by the maximum number of terminals that the secondary cell can access, thereby normalizing the number of terminals currently accessing the secondary cell. Of course, the number of terminals currently accessing the secondary cell may also be multiplied by a preset coefficient and then divided by the maximum number of terminals that the secondary cell can access, thereby normalizing the number of terminals currently accessing the secondary cell. The specific implementation method of normalization may be set as required.

[0096] Step B: normalize the current PRB load.

[0097] For the obtained current PRB load, the current PRB load may be normalized by dividing it by a preset value, which may be 100 or 200, etc., and may be set as required; the current PRB load may also be normalized by standard deviation. The embodiment of the present invention does not limit the specific implementation method of the normalization of the current PRB load.

[0098] In the embodiment of the present invention, both step A and step B may be executed, or only one of step A and step B may be executed. Specifically, as long as step A or step B is executed, the result after execution is used to participate in the calculation of the final value load in step S102.

[0099] In one embodiment of the present invention, both step A and step B are executed, and in step A, the number of terminals currently accessing the secondary cell is divided by the maximum number of terminals that can be accessed by the secondary cell to normalize the number of terminals currently accessing the secondary cell, and the normalized number of terminals currently accessing the secondary cell can be recorded as p_ue; in step B, the current PRB load is divided by 100 to achieve normalization of the current PRB load, and the normalized current PRB load can be recorded as p_load.

[0100] After the number of terminals currently accessing the secondary cell and the current PRB load are normalized, the normalized number of terminals currently accessing the secondary cell and the normalized current PRB load are used to calculate the final value load of the secondary cell in step S102.

[0101] Step S103: when the final load is less than the preset CA configuration threshold of the secondary cell, an A4 measurement event for the secondary cell is sent to the terminal newly accessing the primary cell, and CA configuration is performed on the terminal according to the A4 measurement result fed back by the terminal.

[0102] If the calculated final value load is less than the preset CA configuration threshold, it is considered that the current overall load of the secondary cell is not very large, and CA configuration is performed on the terminal newly connected to the primary cell, which can improve the signal perception of the newly connected terminal and will not cause a decrease in the signal perception of other terminals that have previously connected to the primary cell and have completed CA configuration. Therefore, when the final value load is less than the preset CA configuration threshold, the network device sends an A4 measurement event to the terminal newly connected to the primary cell, and performs CA configuration on the newly connected terminal according to the A4 measurement result fed back by the newly connected terminal.

[0103] Specifically, the preset CA configuration threshold may be set based on comprehensive considerations of factors such as the number of historical access terminals of the secondary cell, historical PRB load, and current actual conditions.

[0104] Step S104: when the final load is not less than the preset CA configuration threshold, terminate the sending of the A4 measurement event for the secondary cell.

[0105] If the calculated final value load is not less than the preset CA configuration threshold, it is considered that the current overall load of the secondary cell is large, and even if the CA configuration is completed for the newly connected terminal, the signal perception of the newly connected terminal will not be improved. Moreover, if the CA configuration is still completed for the newly connected terminal when the overall load is large, the signal perception of other terminals that have previously accessed the primary cell and completed the CA configuration may decrease. Therefore, when the above-mentioned final value load is not less than the preset CA configuration threshold, the network device will not perform CA configuration for the terminal newly connected to the above-mentioned primary cell, that is, it will stop sending the A4 measurement event to the terminal newly connected to the above-mentioned primary cell.

[0106] In addition, when the above-mentioned final value load is not less than the preset CA configuration threshold, the network device will no longer process the received A4 measurement results, that is, the number of terminals in the CA state will no longer be increased.

[0107] In the embodiment of the present invention, both step S103 and step S104 may be executed, or only one of step S103 and step S104 may be executed.

[0108] As can be seen from the above, in the solution provided by the embodiment of the present invention, the number of terminals currently connected to the secondary cell and the current PRB load are obtained, the final value load of the secondary cell is calculated, and the corresponding CA configuration strategy is adopted for the terminal according to the comparison between the final value load and the preset CA configuration threshold. Since the number of terminals currently connected to the secondary cell and the current PRB load are considered at the same time, the final value load obtained can more realistically reflect the overall load status of the secondary cell including the cell operation load and signaling overhead. When the final value load is less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is not very large. After CA configuration is performed on the newly connected terminal, the signal perception of the newly connected terminal can be improved, and the signal perception of other terminals that have completed CA configuration based on the above-mentioned secondary cell will not be reduced. When the final value load is not less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is large. Even if the CA configuration is completed for the newly connected terminal based on the secondary cell, the signal perception of the newly connected terminal will not be improved, and the signal perception of other terminals that have completed CA configuration based on the secondary cell will decrease. Therefore, in this case, the A4 measurement event for the secondary cell is terminated for the newly connected terminal, and CA configuration for the secondary cell is not performed for the newly connected terminal. Therefore, the solution provided by the embodiment of the present invention can flexibly adopt the corresponding CA configuration strategy to perform CA configuration on the terminal according to the actual situation, so that the signal perception of the terminal can be improved after CA configuration.

[0109] Since the purpose of performing CA configuration on the terminal is to enable the terminal to effectively handle a large amount of business, and when the final value load is not less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is large. In order to alleviate the overall load of the secondary cell and control the overall load of the network device, the relevant conditions that the terminal needs to meet in the CA state can be adjusted. Therefore, the embodiment of the present invention provides the following Figure 2 The embodiment shown.

[0110] See also Figure 2 , is a flow chart of a second method for configuring a cell terminal CA according to an embodiment of the present invention, which is applied to a network device, and is similar to the above Figure 1 Compared with the embodiment shown, the method further includes the following steps S105 and S106.

[0111] Step S105: when the final load is not less than the preset CA configuration threshold, it is determined whether the final load is less than the preset CA adjustment threshold of the secondary cell.

[0112] The preset CA adjustment threshold is: the sum of the product of the preset CA configuration threshold and the first adjustment coefficient and the preset CA configuration threshold. Specifically, if the first adjustment coefficient is written as x, the preset CA adjustment threshold is (1+x) times the preset CA configuration threshold.

[0113] Specifically, the preset CA adjustment threshold is used to determine whether it is necessary to adjust the relevant conditions that the current terminal needs to meet in the CA state. If the final value load is less than the preset CA adjustment threshold, it is not necessary to adjust the relevant conditions that the current terminal needs to meet in the CA state; if the final value load is not less than the preset CA adjustment threshold, it is necessary to adjust the relevant conditions that the current terminal needs to meet in the CA state, that is, execute the following step S106.

[0114] Step S106: increasing the preset CA activation threshold of the secondary cell based on the second adjustment coefficient, and / or increasing the preset CA deactivation threshold of the secondary cell based on the third adjustment coefficient.

[0115] The preset CA activation threshold means that after the service volume of the terminal reaches the preset CA activation threshold, the CA service can be performed based on the secondary cell.

[0116] The preset CA deactivation threshold means that the CA service of the terminal is deactivated after the service volume of the terminal using the secondary cell is less than the preset CA deactivation threshold.

[0117] On the one hand, since the above-mentioned final value load is not less than the preset CA adjustment threshold, and the preset CA adjustment threshold is: the product of the above-mentioned preset CA configuration threshold and the first adjustment coefficient and the sum of the above-mentioned preset CA configuration threshold, it indicates that the current overall load of the network device has increased a lot, so it is necessary to restrict the terminal performing CA services, otherwise the overall load of the network device will further increase. The above-mentioned restriction method is to increase the preset CA activation threshold, that is, after the terminal's business volume is further increased, after reaching the increased preset CA activation threshold, for the terminal that has completed CA configuration, it meets the conditions for activating the CA service, that is, it can perform CA services based on the above-mentioned secondary cell. Exemplarily, before increasing the preset CA activation threshold, the value of the preset CA activation threshold is M, then the terminal's business volume reaches M, and the CA service can be activated; after increasing the preset CA activation threshold, the value of the preset CA activation threshold is N, N>M, then the terminal's business volume needs to reach N before the CA service can be activated. Specifically, if the second adjustment coefficient is written as y, then in an example, N is (1+y) times of M.

[0118] After increasing the preset CA activation threshold, the network device judges the service volume of the terminal that has completed CA configuration but has not activated CA service according to the increased preset CA activation threshold. If the service volume of the terminal does not reach the increased preset CA activation threshold, the network device will not activate the CA service of the terminal.

[0119] On the other hand, the overall load of the network equipment can also be alleviated by adjusting the number of terminals that have activated CA services. Specifically, by increasing the preset CA deactivation threshold, the threshold for deactivating CA services for terminals is lowered. Exemplarily, before increasing the preset CA deactivation threshold, the value of the preset CA deactivation threshold is P. For terminals that have activated CA services, the terminal's traffic volume is less than P, and the terminal is deactivated for CA services, and the terminal leaves the CA state; after increasing the preset CA deactivation threshold, the value of the preset CA deactivation threshold is Q, Q>P, then for terminals that have activated CA services, as long as the terminal's traffic volume is less than Q, the terminal can be deactivated for CA services, and the terminal leaves the CA state, reducing the overall load of the primary and secondary cells. Specifically, if the third adjustment coefficient is written as z, then in one example, Q is (1+z) times P.

[0120] In the embodiment of the present invention, the preset CA activation threshold and the preset CA deactivation threshold of the secondary cell may be increased simultaneously, or only the preset CA activation threshold of the secondary cell may be increased, or only the preset CA and activation thresholds of the secondary cell may be increased.

[0121] As can be seen from the above, in the solution provided by the embodiment of the present invention, by increasing the preset CA activation threshold, for the terminal that has completed the CA configuration, the conditions that the terminal must meet to activate the CA service are increased, so that when the current overall load of the network device is greatly increased, the growth rate of the number of terminals that meet the CA service activation conditions is slowed down, and the overall load of the network device is prevented from further increasing too quickly. In addition, by increasing the preset CA deactivation threshold, the threshold for the terminal to deactivate the CA service is lowered, so that some terminals that do not trigger the deactivation of the CA service conditions before increasing the preset CA deactivation threshold meet the conditions for deactivating the CA service after increasing the preset CA deactivation threshold, thereby leaving the CA state, which can alleviate the overall load of the network device. In addition, after some terminals leave the CA state, the newly connected new terminals that meet the CA service activation conditions have the opportunity to activate the CA service, so that the newly connected terminals that meet the CA service activation conditions will not be unable to activate the CA service for a long time.

[0122] The communication status of network equipment will change over time, and the communication configuration strategy for the terminal accessing the primary cell should also be adjusted in time. In one embodiment of the present invention, after the above step S103 or step S104, the following step C is also included.

[0123] Step C: After a preset delay time, re-execute the above steps S101 to S103, or re-execute the above steps S101 to S104.

[0124] Specifically, the preset delay time can be set according to actual conditions. For example, the preset delay time can be set to 15 minutes, 20 minutes, or 22 minutes.

[0125] From the above, it can be seen that in the solution provided in the embodiment of the present invention, the above-mentioned steps of obtaining the number of terminals currently accessing the secondary cell and the current PRB load and subsequent steps are re-executed every time a preset delay period has passed, so that the CA configuration strategy for the terminal can be adjusted in time when the communication status of the network device changes over time.

[0126] In one embodiment of the present invention, the final value load is calculated in the following manner, which specifically includes the following steps D to G.

[0127] Step D: multiply the number of terminals currently accessing the secondary cell by the fourth adjustment coefficient to obtain a first intermediate value.

[0128] Specifically, the number of terminals currently accessing the secondary cell is recorded as p_ue, the fourth adjustment coefficient is written as w, and the first intermediate value is recorded as i1, then i1=w*p_ue, where "*" represents multiplication.

[0129] Step E: Calculate the product of the current PRB load and the fourth adjustment coefficient.

[0130] Specifically, the current PRB load is recorded as p_load, and the product is w*p_load.

[0131] Step F: Calculate the difference between the current PRB load and the product to obtain a second intermediate value.

[0132] Specifically, the second intermediate value is recorded as i2, then i2=p_load-w*p_load.

[0133] Step G: Calculate the arithmetic mean of the first intermediate value and the second intermediate value to obtain the final value load.

[0134] Specifically, the final value load is recorded as P_last, and the calculation formula for P_last is: P_last = (i1 + i2) / 2 = (w * p_ue + p_load - w * p_load) / 2 = (w * p_ue + (1-w) * p_load) / 2, the fourth adjustment coefficient w is a coefficient set according to actual needs, and the coefficient w can be adjusted so that the calculated final value load conforms to the actual situation that the number of terminals currently accessing the above-mentioned secondary cell is large or the above-mentioned current PRB load is large.

[0135] In one embodiment of the present invention, the values ​​of the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient are the same. This setting can adjust the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient at one time, thereby reducing the difficulty of implementing the cell terminal CA configuration method and ensuring that the proportional changes of the expansion and reduction of the relevant thresholds are relatively consistent.

[0136] See also Figure 3 , is a flow chart of a third cell terminal CA configuration method provided in an embodiment of the present invention, the method is applied to a network device, and the method includes the following steps S301 to S311.

[0137] Step S301: Acquire the number of terminals currently accessing the secondary cell and the maximum number of terminals that can access the secondary cell.

[0138] Step S302: the number of terminals currently accessing the secondary cell is divided by the maximum number of terminals accessible to the secondary cell to obtain a normalized result of the number of terminals currently accessing the secondary cell.

[0139] Specifically, the number of terminals currently connected to the secondary cell is recorded as p_ue, and the maximum number of terminals that can be connected to the secondary cell is recorded as p_ue_max. The normalized result p_ue of the number of terminals currently connected to the secondary cell is / =p_ue / p_ue_max.

[0140] Step S303: Acquire the current PRB load of the secondary cell.

[0141] Step S304: divide the current PRB load by 100 to normalize the current PRB load.

[0142] Specifically, the current PRB load is recorded as p_load, and the normalized result p_load of the current PRB load is / =p_load / 100*100%.

[0143] Step S305: Set the target coefficient v.

[0144] Specifically, 0 < v < 1. Additionally, the value of v used this time can also be the value of the coefficient v used in the previous CA configuration for the terminal.

[0145] Step S306: Multiply the normalization result of the current number of terminals connected to the secondary cell by the coefficient v to obtain a fifth intermediate value. Subtract the product of the normalization result of the current PRB load and the coefficient v from the normalization result of the current PRB load to obtain a sixth intermediate value. Calculate the average of the fifth intermediate value and the sixth intermediate value to obtain the final load.

[0146] Specifically, denote the final load as P_last, then P_last = (v * p_ue / + (1 - v) * p_load / ) / 2.

[0147] Step S307: Determine whether the above final load is less than the preset CA configuration threshold.

[0148] Specifically, the value of the preset CA configuration threshold used this time can be the value of the preset CA configuration threshold used in the previous CA configuration for the terminal.

[0149] If it is determined that the above final load is less than the preset CA configuration threshold, then execute the following step S308; otherwise, execute the following step S309.

[0150] Step S308: Send an A4 measurement event to the terminal newly connected to the primary cell, and perform CA configuration on the terminal according to the A4 measurement result feedback by the terminal.

[0151] After determining that the above final load is less than the preset CA configuration threshold and executing step S308, after waiting for the preset delay duration, steps S301 and subsequent steps can be executed again.

[0152] Step S309: Terminate sending the A4 measurement event to the terminal newly connected to the primary cell.

[0153] Additionally, if it is determined that the above final load is not less than the preset CA configuration threshold, the network device will no longer process the received A4 measurement results.

[0154] Step S310: Use the above preset CA configuration threshold plus the product of the preset CA configuration threshold and v to obtain a preset CA adjustment threshold, and determine whether the above final load is less than the preset CA adjustment threshold.

[0155] Specifically, if it is determined that the above-mentioned final value load is less than the preset CA adjustment threshold, there is no need to adjust the relevant conditions that the current terminal needs to meet in the CA state, and after waiting for the preset delay time, re-execute step S301 and the subsequent steps; if it is determined that the above-mentioned final value load is not less than the preset CA adjustment threshold, it is necessary to adjust the relevant conditions that the current terminal needs to meet in the CA state, that is, execute the following step S311.

[0156] Step S311: add the existing preset CA activation threshold to the product of the existing preset CA activation threshold and v to obtain an increased preset CA activation threshold; add the existing preset CA deactivation threshold to the product of the existing preset CA deactivation threshold and v to obtain an increased preset CA deactivation threshold.

[0157] Specifically, the increased preset CA activation threshold and the increased preset CA deactivation threshold are used in the subsequent CA configuration of the terminal.

[0158] After executing the above step S311, wait for a preset delay time, and then re-execute step S301 and subsequent steps.

[0159] exist Figure 3 In the illustrated embodiment, according to the comparison between the final value load and the preset CA configuration threshold, the corresponding CA configuration strategy is adopted for the terminal, which can avoid the situation that the signal perception of the newly connected terminal is still not improved after the CA configuration, and the signal perception of other terminals that have been configured with CA before is reduced. In addition, there will be no problem that the terminal signal perception cannot be improved through CA configuration, but the overall signaling overhead of the system is increased due to the sending and receiving of signaling in the CA configuration. Therefore, the solution provided by the embodiment of the present invention can reduce the signaling overhead of the network device in the CA configuration when the overall load of the secondary cell is high, so that the limited resources in the network device can be used to ensure the average signal perception of each terminal. By increasing the preset CA activation threshold and the preset CA deactivation threshold, the number of terminals performing CA services is reduced, forming positive feedback, and gradually reducing the overall load of the secondary cell. In addition, a target coefficient runs through the entire process of CA configuration of the cell terminal, which reduces the difficulty of implementing the CA configuration method of the cell terminal, and ensures that the proportion of the expansion and reduction of the relevant thresholds is relatively consistent.

[0160] The technical solution provided by the embodiment of the present invention can be applicable to a variety of systems, for example, the applicable system may be a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system and its evolved communication system, etc. These various systems may include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDA), personal computers, tablet computers, Machine-type Communication (MTC) terminal devices, etc. Wireless terminal devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal devices, access terminal devices, user terminal devices, user agents, user devices, and wireless access points and routers / modems that meet the limitations of this definition, which are not limited in the embodiments of the present invention.

[0162] Corresponding to the aforementioned cell terminal CA configuration method applied to a network device, an embodiment of the present invention further provides a network device.

[0163] See also Figure 4 , is a schematic diagram of the structure of a network device provided in an embodiment of the present invention, including a memory 401, a transceiver 402, and a processor 403:

[0164] The memory 401 is used to store computer programs; the transceiver 402 is used to send and receive data under the control of the processor 403; the processor 403 is used to implement the following method steps when executing the program stored in the memory 401:

[0165] Obtain the number of terminals currently connected to the secondary cell and the current PRB load;

[0166] Calculating a final load of the secondary cell based on the number of terminals and the current PRB load;

[0167] When the final value load is less than the preset CA configuration threshold of the secondary cell, an A4 measurement event for the secondary cell is sent to a terminal newly accessing the primary cell, and CA configuration is performed on the terminal according to the A4 measurement result fed back by the terminal;

[0168] and / or

[0169] When the final load is not less than the preset CA configuration threshold, the sending of the A4 measurement event for the secondary cell is terminated.

[0170] Among them, Figure 4 In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically one or more processors represented by processor 403 and various circuits of memory represented by memory 401 are linked together. The bus architecture may also link together various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface. The transceiver 402 may be a plurality of components, namely, a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium, which transmission medium may include a wireless channel, a wired channel, an optical cable, and other transmission media. The processor 403 is responsible for managing the bus architecture and general processing, and the memory 401 may store data used by the processor 403 when performing operations.

[0171] The processor 403 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or a complex programmable logic device (CPLD). The processor may also adopt a multi-core architecture.

[0172] As can be seen from the above, in the solution provided by the embodiment of the present invention, the number of terminals currently connected to the secondary cell and the current PRB load are obtained, the final value load of the secondary cell is calculated, and the corresponding CA configuration strategy is adopted for the terminal according to the comparison between the final value load and the preset CA configuration threshold. Since the number of terminals currently connected to the secondary cell and the current PRB load are considered at the same time, the final value load obtained can more realistically reflect the overall load status of the secondary cell including the cell operation load and signaling overhead. When the final value load is less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is not very large. After CA configuration is performed on the newly connected terminal, the signal perception of the newly connected terminal can be improved, and the signal perception of other terminals that have completed CA configuration based on the above-mentioned secondary cell will not be reduced. When the final value load is not less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is large. Even if the CA configuration is completed for the newly connected terminal based on the secondary cell, the signal perception of the newly connected terminal will not be improved, and the signal perception of other terminals that have completed CA configuration based on the secondary cell will decrease. Therefore, in this case, the A4 measurement event for the secondary cell is terminated for the newly connected terminal, and CA configuration for the secondary cell is not performed for the newly connected terminal. Therefore, the solution provided by the embodiment of the present invention can flexibly adopt the corresponding CA configuration strategy to perform CA configuration on the terminal according to the actual situation, so that the signal perception of the terminal can be improved after CA configuration.

[0173] In one embodiment of the present invention, the processor 403 is further configured to execute the program stored in the memory 401 to perform the following operations:

[0174] In a case where the final value load is not less than the preset CA configuration threshold, determining whether the final value load is less than the preset CA adjustment threshold of the secondary cell, wherein the preset CA adjustment threshold is: the sum of the product of the preset CA configuration threshold and the first adjustment coefficient and the preset CA configuration threshold;

[0175] If not, increasing the preset CA activation threshold of the secondary cell based on the second adjustment coefficient, and / or increasing the preset CA deactivation threshold of the secondary cell based on the third adjustment coefficient;

[0176] Among them, the preset CA activation threshold means: after the terminal's business volume reaches the above-mentioned preset CA activation threshold, CA service can be performed based on the above-mentioned secondary cell; the preset CA deactivation threshold means: after the business volume of the terminal using the above-mentioned secondary cell is less than the above-mentioned preset CA deactivation threshold, the CA service of the terminal is deactivated.

[0177] As can be seen from the above, in the solution provided by the embodiment of the present invention, by increasing the preset CA activation threshold, for the terminal that has completed the CA configuration, the conditions that the terminal must meet to activate the CA service are increased, so that when the current overall load of the network device is greatly increased, the growth rate of the number of terminals that meet the CA service activation conditions is slowed down, and the overall load of the network device is prevented from further increasing too quickly. In addition, by increasing the preset CA deactivation threshold, the threshold for the terminal to deactivate the CA service is lowered, so that some terminals that do not trigger the deactivation of the CA service conditions before increasing the preset CA deactivation threshold meet the conditions for deactivating the CA service after increasing the preset CA deactivation threshold, thereby leaving the CA state, which can alleviate the overall load of the network device. In addition, after some terminals leave the CA state, the newly connected new terminals that meet the CA service activation conditions have the opportunity to activate the CA service, so that the newly connected terminals that meet the CA service activation conditions will not be unable to activate the CA service for a long time.

[0178] In one embodiment of the present invention, after the A4 measurement event for the secondary cell is sent to the terminal newly accessing the primary cell, and CA configuration is performed on the terminal according to the A4 measurement result fed back by the terminal, or after the A4 measurement event for the secondary cell is terminated, the processor 403 is further used to execute the program stored in the memory 401 to perform the following operations:

[0179] After a preset delay period, the above steps of obtaining the number of terminals currently connected to the secondary cell and the current PRB load, sending the A4 measurement event for the secondary cell to the terminal newly connected to the main cell, and performing CA configuration for the terminal according to the A4 measurement result fed back by the terminal and / or terminating the sending of the A4 measurement event for the secondary cell are executed again.

[0180] From the above, it can be seen that in the solution provided in the embodiment of the present invention, the above-mentioned steps of obtaining the number of terminals currently accessing the secondary cell and the current PRB load and subsequent steps are re-executed every time a preset delay period has passed, so that the CA configuration strategy for the terminal can be adjusted in time when the communication status of the network device changes over time.

[0181] In one embodiment of the present invention, before calculating the final value load of the secondary cell based on the number of terminals and the current PRB load, the processor 403 is further configured to execute the program stored in the memory 401 to perform the following operations:

[0182] Based on the maximum number of terminals that can be accessed by the secondary cell, normalizing the number of terminals currently accessing the secondary cell;

[0183] and / or

[0184] The current PRB load is normalized.

[0185] Specifically, the normalization process can reduce the adverse effect of fluctuations in the size of the calculated data on the calculated final value load.

[0186] In one embodiment of the present invention, the final value load is calculated in the following manner:

[0187] Multiplying the number of terminals currently connected to the secondary cell by a fourth adjustment coefficient to obtain a first intermediate value;

[0188] Calculate the product of the current PRB load and the fourth adjustment coefficient;

[0189] Calculate the difference between the current PRB load and the product to obtain a second intermediate value;

[0190] The arithmetic mean of the first intermediate value and the second intermediate value is calculated to obtain the final value load.

[0191] In one embodiment of the present invention, the values ​​of the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient are the same. This setting can adjust the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient at one time, thereby reducing the difficulty of implementing the cell terminal CA configuration method and ensuring that the proportional changes of the expansion and reduction of the relevant thresholds are relatively consistent.

[0192] It should be noted here that the above-mentioned network device provided in the embodiment of the present invention can implement all the method steps implemented in the above-mentioned method embodiment and can achieve the same technical effect.

[0193] Since the network device and the cell terminal CA configuration method provided by the embodiments of the present invention are based on the same application concept and have similar principles for solving problems, the embodiments of the network device and the cell terminal CA configuration method can refer to each other and the repeated parts will not be repeated.

[0194] The network device involved in the embodiment of the present invention may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to exchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiment of the present invention may be an evolutionary network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), etc., or a home evolved Node B (HeNB), a relay node, a home base station (femto), a pico base station (pico), a network test device, etc., which is not limited in the embodiment of the present invention. In some network structures, the network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0195] Corresponding to the aforementioned cell terminal CA configuration method applied to a network device, an embodiment of the present invention further provides a cell terminal CA configuration device.

[0196] See also Figure 5 , is a structural diagram of a cell terminal CA configuration device provided by an embodiment of the present invention, the device is applied to a network device, and the device includes:

[0197] The acquisition module 501 is used to acquire the number of terminals currently accessing the secondary cell and the current PRB load.

[0198] The calculation module 502 is used to calculate the final value load of the secondary cell based on the number of terminals and the current PRB load.

[0199] The sending and configuring module 503 is used to send the A4 measurement event for the secondary cell to the terminal newly accessing the primary cell when the final value load is less than the preset CA configuration threshold of the secondary cell, and perform CA configuration on the terminal according to the A4 measurement result fed back by the terminal.

[0200] and / or

[0201] The termination module 504 is configured to terminate sending the A4 measurement event for the secondary cell when the final load is not less than a preset CA configuration threshold.

[0202] As can be seen from the above, in the solution provided by the embodiment of the present invention, the number of terminals currently connected to the secondary cell and the current PRB load are obtained, the final value load of the secondary cell is calculated, and the corresponding CA configuration strategy is adopted for the terminal according to the comparison between the final value load and the preset CA configuration threshold.

When the final value load is not less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is large. Even if the CA configuration is completed for the newly connected terminal based on the secondary cell, the signal perception of the newly connected terminal will not be improved, and the signal perception of other terminals that have completed CA configuration based on the secondary cell will decrease. Therefore, in this case, the A4 measurement event for the secondary cell is terminated for the newly connected terminal, and CA configuration for the secondary cell is not performed for the newly connected terminal. Therefore, the solution provided by the embodiment of the present invention can flexibly adopt the corresponding CA configuration strategy to perform CA configuration on the terminal according to the actual situation, so that the signal perception of the terminal can be improved after CA configuration.

[0203] In one embodiment of the present invention, the above device further includes:

[0204] The judgment module 505 is used to judge whether the above-mentioned final value load is less than the preset CA adjustment threshold of the above-mentioned secondary cell when the above-mentioned final value load is not less than the preset CA configuration threshold, wherein the above-mentioned preset CA adjustment threshold is: the sum of the product of the above-mentioned preset CA configuration threshold and the first adjustment coefficient and the above-mentioned preset CA configuration threshold.

[0205] The increasing module 506 is used to increase the preset CA activation threshold of the secondary cell based on the second adjustment coefficient and / or increase the preset CA deactivation threshold of the secondary cell based on the third adjustment coefficient when the judging module judges that the final value load is not less than the preset CA adjustment threshold.

[0206] Among them, the preset CA activation threshold means: after the terminal's business volume reaches the above-mentioned preset CA activation threshold, CA service can be performed based on the above-mentioned secondary cell; the preset CA deactivation threshold means: after the business volume of the terminal using the above-mentioned secondary cell is less than the above-mentioned preset CA deactivation threshold, the CA service of the terminal is deactivated.

[0207] As can be seen from the above, in the solution provided by the embodiment of the present invention, by increasing the preset CA activation threshold, for the terminal that has completed the CA configuration, the conditions that the terminal must meet to activate the CA service are increased, so that when the current overall load of the network device is greatly increased, the growth rate of the number of terminals that meet the CA service activation conditions is slowed down, and the overall load of the network device is prevented from further increasing too quickly. In addition, by increasing the preset CA deactivation threshold, the threshold for the terminal to deactivate the CA service is lowered, so that some terminals that do not trigger the deactivation of the CA service conditions before increasing the preset CA deactivation threshold meet the conditions for deactivating the CA service after increasing the preset CA deactivation threshold, thereby leaving the CA state, which can alleviate the overall load of the network device. In addition, after some terminals leave the CA state, the newly connected new terminals that meet the CA service activation conditions have the opportunity to activate the CA service, so that the newly connected terminals that meet the CA service activation conditions will not be unable to activate the CA service for a long time.

[0208] In one embodiment of the present invention, the above device further includes:

[0209] The re-execution module 507 is used to re-execute the above-mentioned steps of obtaining the number of terminals currently connected to the secondary cell and the current PRB load to send the A4 measurement event for the above-mentioned secondary cell to the terminal newly connected to the above-mentioned main cell after a preset delay period, and performing CA configuration on the above-mentioned terminal according to the A4 measurement result fed back by the above-mentioned terminal and / or terminating the step of sending the A4 measurement event for the above-mentioned secondary cell.

[0210] From the above, it can be seen that in the solution provided in the embodiment of the present invention, the above-mentioned steps of obtaining the number of terminals currently accessing the secondary cell and the current PRB load and subsequent steps are re-executed every time a preset delay period has passed, so that the CA configuration strategy for the terminal can be adjusted in time when the communication status of the network device changes over time.

[0211] In one embodiment of the present invention, the above device further includes:

[0212] A normalization module 508, configured to normalize the number of terminals currently accessing the secondary cell based on the maximum number of terminals accessible to the secondary cell;

[0213] and / or

[0214] The current PRB load is normalized.

[0215] Specifically, the normalization process can reduce the adverse effect of fluctuations in the size of the calculated data on the calculated final value load.

[0216] In one embodiment of the present invention, the calculation module 502 is specifically used for:

[0217] Multiplying the number of terminals currently connected to the secondary cell by a fourth adjustment coefficient to obtain a first intermediate value;

[0218] Calculate the product of the current PRB load and the fourth adjustment coefficient;

[0219] Calculate the difference between the current PRB load and the product to obtain a second intermediate value;

[0220] The arithmetic mean of the first intermediate value and the second intermediate value is calculated to obtain the final value load.

[0221] In one embodiment of the present invention, the values ​​of the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient are the same. This setting can adjust the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient at one time, thereby reducing the difficulty of implementing the cell terminal CA configuration method and ensuring that the proportional changes of the expansion and reduction of the relevant thresholds are relatively consistent.

[0222] It should be noted here that the above-mentioned device provided by the embodiment of the present invention can implement all the method steps implemented by the above-mentioned method embodiment and can achieve the same technical effect.

[0223] Since the cell terminal CA configuration device and the cell terminal CA configuration method provided in the embodiments of the present invention are based on the same application concept and have similar principles for solving problems, the embodiments of the cell terminal CA configuration device and the cell terminal CA configuration method can refer to each other and the repeated parts will not be repeated.

[0224] It should be noted that the division of modules in the embodiments of the present invention is schematic and is only a logical function division. There may be other division methods in actual implementation. In addition, the functional modules in the various embodiments of the present invention may be integrated into a processing module, or each module may exist physically separately, or two or more modules may be integrated into one module. The above-mentioned integrated modules may be implemented in the form of hardware or in the form of software functional modules.

[0225] In another embodiment of the present invention, a computer-readable storage medium is provided, in which a computer program is stored. When the computer program is executed by a processor, the steps of any of the above-mentioned cell terminal CA configuration methods are implemented.

[0226] When the computer program stored in the computer-readable storage medium provided by the embodiment of the present invention is applied to perform CA configuration of the cell terminal, the number of terminals currently connected to the secondary cell and the current PRB load are obtained, the final value load of the secondary cell is calculated, and the corresponding CA configuration strategy is adopted for the terminal according to the comparison between the final value load and the preset CA configuration threshold. Since the number of terminals currently connected to the secondary cell and the current PRB load are considered at the same time, the final value load obtained can more realistically reflect the overall load status of the secondary cell including the cell operation load and signaling overhead. When the final value load is less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is not very large. After CA configuration is performed on the newly connected terminal, the signal perception of the newly connected terminal can be improved, and the signal perception of other terminals that have completed CA configuration based on the above-mentioned secondary cell will not be reduced. When the final value load is not less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is large. Even if the CA configuration is completed for the newly connected terminal based on the secondary cell, the signal perception of the newly connected terminal will not be improved, and the signal perception of other terminals that have completed CA configuration based on the secondary cell will decrease. Therefore, in this case, the A4 measurement event for the secondary cell is terminated for the newly connected terminal, and CA configuration for the secondary cell is not performed for the newly connected terminal. Therefore, the solution provided by the embodiment of the present invention can flexibly adopt the corresponding CA configuration strategy to perform CA configuration on the terminal according to the actual situation, so that the signal perception of the terminal can be improved after CA configuration.

Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art or all or part of the technical solution can be embodied in the form of a software product. The computer software product is stored in a storage medium, including several instructions for a computer device (which can be a personal computer, server, or network device, etc.) or a processor (processor) to perform all or part of the steps of the above-mentioned methods of each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (Read-Only Memory, ROM), random access memory (Random Access Memory, RAM), disk or optical disk and other media that can store program codes.

[0228] In another embodiment of the present invention, a computer program product including instructions is provided. When the computer program product is run on a computer, the computer executes any of the cell terminal CA configuration methods in the above embodiments.

[0229] When the computer program product provided by the embodiment of the present invention is applied to perform CA configuration of the cell terminal, the number of terminals currently connected to the secondary cell and the current PRB load are obtained, the final value load of the secondary cell is calculated, and the corresponding CA configuration strategy is adopted for the terminal according to the comparison between the final value load and the preset CA configuration threshold. Since the number of terminals currently connected to the secondary cell and the current PRB load are considered at the same time, the final value load obtained can more realistically reflect the overall load status of the secondary cell including the cell operation load and signaling overhead. When the final value load is less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is not very large. After CA configuration is performed on the newly connected terminal, the signal perception of the newly connected terminal can be improved, and the signal perception of other terminals that have completed CA configuration based on the above-mentioned secondary cell will not be reduced. When the final value load is not less than the preset CA configuration threshold, it indicates that the current overall load of the secondary cell is large. Even if the CA configuration is completed for the newly connected terminal based on the secondary cell, the signal perception of the newly connected terminal will not be improved, and the signal perception of other terminals that have completed CA configuration based on the secondary cell will decrease. Therefore, in this case, the A4 measurement event for the secondary cell is terminated for the newly connected terminal, and CA configuration for the secondary cell is not performed for the newly connected terminal. Therefore, the solution provided by the embodiment of the present invention can flexibly adopt the corresponding CA configuration strategy to perform CA configuration on the terminal according to the actual situation, so that the signal perception of the terminal can be improved after CA configuration.
