Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method, apparatus, electronic device, and storage medium for analyzing the reservation of radio network slice resources. Background Art

[0002] The 5G network is oriented to three major service scenarios: enhanced mobile broadband, massive machine communication, and ultra-reliable and low-latency communication. With a brand-new network architecture, it has opened a new era of extensive interconnection of all things and in-depth human-machine interaction. "Network slicing" is one of the landmark technologies that distinguish 5G from 4G. The 5G network slicing technology involves QoS, slicing, and slice scheduling, etc. By providing logical "private networks" to serve vertical industries, it is a powerful tool for operators to expand industry customers, spawn new services, and improve network value. The 5G network slicing technology can provide users with a better network experience through the reservation of slice resources. How to reserve network resources and configure slices, and how to display slice capabilities to users are worthy of in-depth study.

[0003] In the existing methods for reserving radio network slice resources, since operators generally do not have the complete slice metric monitoring ability at the SLA level and generally do not achieve automatic reservation and optimization of slice resources, currently, slice reservation is mainly configured by on-site optimization personnel based on experience. Usually, more resources are reserved to ensure that service requirements can be met. However, the resource reservation of a certain slice will affect the ability of the base station to serve other slices, and excessive reservation will result in resource waste; when users want to understand the effect of slice reservation, currently, they can only be introduced orally or compared through peak speed measurement. However, the peak rate is not the usage scenario for most slice reservations and cannot well fit the actual services of users. The market needs a more intuitive and easy-to-understand way to display slice capabilities. Summary of the Invention

[0056] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0057] The following will describe Figures 1-4 the method, device, electronic device, and storage medium for analyzing the reserved resources of a wireless network slice of the present invention.

[0058] Figure 1 shows a schematic flowchart of a method for analyzing the reserved resources of a wireless network slice of the present invention. Refer to Figure 1 , the method includes:

[0059] 11. Configure a first network slice for the primary coverage cell and configure an initial uplink resource reservation ratio for the first network slice;

[0060] 12. Determine the ranking of the noise floor impact of each neighboring cell on the primary coverage cell, and determine the uplink rate peak of the first network slice according to the uplink packet filling test of the test terminals in each neighboring cell;

[0061] 13. Determine the planned uplink resource reservation ratio of the first network slice according to the uplink rate peak, the initial uplink resource reservation ratio, and the uplink code rate requirement value of the test device placed in the first network slice;

[0062] 14. According to the plan, perform uplink packet filling tests on the test devices in the primary coverage cell using the uplink resource reservation ratio to determine the uplink resource reservation ratio of the first network slice.

[0063] Regarding steps 11 - 14, it should be noted that in the present invention, in communication transmission, there is an impact of background noise between cells. Therefore, for the primary coverage cell, it is necessary to determine the impact of each neighboring cell on the background noise of the primary coverage cell, and determine the sorting of the impact of each neighboring cell on the background noise according to the preset number and the magnitude of the background noise impact.

[0064] In the present invention, this method is used for the analysis and determination of the uplink resource reservation ratio of network slices. Therefore, first, a network slice is configured for the primary coverage cell. For the subsequent description of the solution, the configured network slice is used as the first network slice, and then an initial uplink resource reservation ratio is configured for the first network slice.

[0065] In the present invention, perform uplink packet filling tests on the test terminals in each neighboring cell until the primary coverage cell reaches the uplink background noise peak value, and then perform the uplink rate test on the first network slice of the primary coverage cell. The peak value that can be achieved is used as the uplink rate peak value of the first network slice.

[0066] In the present invention, after obtaining the uplink rate peak value and the initial uplink resource reservation ratio, configure the uplink code rate requirement value of the test device placed in the first network slice, and then perform a preset algorithm based on the uplink rate peak value, the initial uplink resource reservation ratio, and the uplink code rate requirement value of the test device placed in the first network slice to calculate the planned uplink resource reservation ratio of the first network slice. During the configuration process of the network slice, this planned uplink resource reservation ratio can be directly used as the uplink resource reservation ratio of the network slice, or can be adjusted as the uplink resource reservation ratio of the network slice. Therefore, perform uplink packet filling tests on the test devices in the primary coverage cell according to the planned uplink resource reservation ratio. During this uplink packet filling test process, the planned uplink resource reservation ratio can be directly used as the uplink resource reservation ratio of the network slice according to the test data, or can be further adjusted according to the test data, and the adjusted uplink resource reservation ratio is used as the uplink resource reservation ratio of the network slice.

[0067] The wireless network slice resource reservation analysis method provided by the embodiments of the present invention calculates by combining the extraction of existing data of the primary coverage cell and on-site tests to obtain the uplink resource reservation ratio of the network slice of the primary coverage cell, realizing efficient and cost-effective slice resource reservation analysis and determination, and providing strong support for the slice capabilities demonstrated by each business hall and large exhibition venues of the operator.

[0068] In the further description of the above method, it mainly explains the process of determining the ranking of the noise floor impact of each neighboring cell on the main coverage cell and determining the uplink rate peak of the first network slice based on the uplink packet injection test of the test terminals in each neighboring cell, as follows:

[0069] Obtain the noise floor data of the main coverage cell and predict the uplink noise floor peak of the main coverage cell according to the noise floor data;

[0070] Obtain the test field strength of each neighboring cell, the handover times between each neighboring cell and the main coverage cell, and the uplink PRB utilization rate;

[0071] Determine the correlation coefficient between the noise floor of the main coverage cell and the uplink PRB utilization rate of each neighboring cell according to the noise floor data and the uplink PRB utilization rate of each neighboring cell;

[0072] Determine the ranking of the noise floor impact of each neighboring cell according to the test field strength of each neighboring cell, the handover times between each neighboring cell and the main coverage cell, and the correlation coefficient between the noise floor of the main coverage cell and the uplink PRB utilization rate of each neighboring cell;

[0073] Based on the ranking of the noise floor impact of each neighboring cell, starting from the neighboring cell with the greatest impact, find the handover edge between the neighboring cell and the main coverage cell, and perform an uplink packet injection test when the test terminal just occupies the neighboring cell, and gradually increase the packet injection rate at a preset first step length until the noise floor of the main coverage cell reaches the uplink noise floor peak;

[0074] When the packet injection rate increases to the rate peak of the neighboring cell with the greatest impact and the noise floor of the main coverage cell does not reach the uplink noise floor peak of the main coverage cell, then let the other neighboring cells continue to perform the uplink packet injection test in sequence until the noise floor of the main coverage cell reaches the uplink noise floor peak of the main coverage cell;

[0075] After the noise floor of the main coverage cell reaches the uplink noise floor peak, perform the uplink rate test of the first network slice of the main coverage cell, and use the peak value that can be achieved as the uplink rate peak of the first network slice.

[0076] In this regard, it should be noted that in the present invention, first, the main coverage cell test is performed in the area where the demonstration terminal needs to demonstrate, record the noise floor data and neighboring cell field strength of the main coverage cell, and record other network data of the main coverage cell to ensure that there are no problems such as coverage, capacity, and interference in the main coverage cell.

[0077] If the main coverage cell network is stable, then predict the uplink noise floor peak of the main coverage cell. If the main coverage cell network is unstable and there are the above various problems, then first perform network optimization. After the optimization is completed, re-record the above data and then predict the uplink noise floor peak of the main coverage cell.

[0078] In the present invention, the uplink noise floor peak value of the main coverage cell is predicted based on the noise floor data. The noise floor data can all be the data with a granularity of 15 minutes in the recent period (including at least one day's data), and the data in the same period is used for comparative analysis of various data.

[0079] In the present invention, the uplink noise floor peak value of the main coverage cell is predicted. For the noise floor peak value under stable network conditions, the maximum value of the extracted noise floor data can be used for estimation.

[0080] The correlation coefficient between the noise floor of the main coverage cell and the uplink PRB utilization rate of each neighboring cell is determined based on the noise floor data and the uplink PRB utilization rate of each neighboring cell.

[0081] In the present invention, for the correlation coefficient between the noise floor data of the main coverage cell and the uplink PRB utilization rate of the neighboring cell, the Pearson correlation coefficient calculation formula can be used for calculation, specifically as follows:

[0082]

[0083] Where r is the correlation coefficient, n is the sample size, and X and Y are the noise floor data and the uplink PRB utilization rate of the neighboring cell respectively.

[0084] In the present invention, based on the test field strength of each neighboring cell, the handover times between each neighboring cell and the main coverage cell, and the correlation coefficient between the noise floor of the main coverage cell and the uplink PRB utilization rate of each neighboring cell, the noise floor impact ranking of each neighboring cell is determined.

[0085] To evaluate the impact of the neighboring cell service on the noise floor of the main coverage cell, it is necessary to use the test field strength of the neighboring cell, the handover times between each neighboring cell and the main coverage cell, the noise floor of the main coverage cell, and the correlation coefficient between the uplink PRB utilization rate of each neighboring cell as scoring indicators, score item by item and sum up the weighted scores and then sort. The higher the score ranking, the greater the impact of the neighboring cell on the noise floor of the main coverage cell.

[0086] In this regard, it should be noted that in the present invention, based on the noise floor impact ranking of each neighboring cell, starting from the neighboring cell with the greatest impact, the handover edge between the neighboring cell and the main coverage cell is found. When the test terminal just occupies the neighboring cell, an uplink packet filling test is carried out, and the packet filling rate is gradually increased in steps of 10 Mbps until the noise floor of the main coverage cell reaches the predicted uplink noise floor peak value. If the packet filling rate has been increased to the peak rate of the neighboring cell with the greatest impact and the uplink noise floor peak value of the main coverage cell has still not been reached, then other neighboring cells are successively continued to carry out the uplink packet filling test until the noise floor of the main coverage cell reaches the uplink noise floor peak value of the main coverage cell.

[0087] For example: There are 4 neighboring cells, and the noise floor impact ranking is a, b, c, d. First, find the handover edge between neighboring cell a and the main coverage cell. When the test terminal just occupies the neighboring cell, perform an uplink packet filling test, and gradually increase the packet filling rate in steps of 10 Mbps until the noise floor of the main coverage cell reaches the predicted uplink noise floor peak value. At this time, when the packet filling rate is increased to the peak rate of the neighboring cell with the greatest impact and still does not reach the uplink noise floor peak value of the main coverage cell, then find the handover edge between neighboring cell b and the main coverage cell. When the test terminal just occupies the neighboring cell, perform an uplink packet filling test, and gradually increase the packet filling rate in steps of 10 Mbps until the noise floor of the main coverage cell reaches the predicted uplink noise floor peak value. At this time, when the packet filling rate is increased to the peak rate of the neighboring cell with the greatest impact and still does not reach the uplink noise floor peak value of the main coverage cell, then find the handover edge between neighboring cell c and the main coverage cell. When the test terminal just occupies the neighboring cell, perform an uplink packet filling test, and gradually increase the packet filling rate in steps of 10 Mbps until the noise floor of the main coverage cell reaches the predicted uplink noise floor peak value. At this time, when the packet filling rate is increased to the peak rate of the neighboring cell with the greatest impact and reaches the uplink noise floor peak value of the main coverage cell, then stop looking for the handover edge between neighboring cell d and the main coverage cell to perform the uplink packet filling test process.

[0088] After the noise floor of the main coverage cell reaches the uplink noise floor peak value, perform the uplink rate test of the network slice of the main coverage cell, and record the peak value that can be reached as the uplink rate peak value of the network slice.

[0089] A further method of the present invention is to perform an uplink packet filling test in a relay manner through neighboring cells ranked by noise floor impact. After the noise floor of the main coverage cell reaches the uplink noise floor peak value, perform the uplink rate test of the network slice of the main coverage cell, and accurately obtain the uplink rate peak value of the network slice.

[0090] In the further description of the above method, it mainly explains the processing process of determining the noise floor impact ranking of each neighboring cell according to the test field strength of each neighboring cell, the handover times between each neighboring cell and the main coverage cell, the noise floor of the main coverage cell, and the correlation coefficient of the uplink PRB utilization rate of each neighboring cell, as follows:

[0091] In the present invention, the scoring method for each index data can adopt the scoring and ranking method, as follows:

[0092] Arrange the actual values of the test field strength of each neighboring cell, the handover times between each neighboring cell and the main coverage cell, the noise floor of the main coverage cell, and the correlation coefficient of the uplink PRB utilization rate of each neighboring cell in descending order according to the quality. Here, the mentioned test field strength, handover times, and correlation coefficient are all positive indicators and are arranged in descending order. If there are inverse indicators in the indicators, they need to be arranged in ascending order.

[0093] Calculate the scores of each neighboring cell for each indicator. The neighboring cell ranked first in the indicator gets 100 points, the neighboring cell ranked last gets 0 points, and for each neighboring cell in the middle, it is calculated separately according to the following formula:

[0094]

[0095] Among them, X i is the score of the i-th indicator of a certain neighboring cell, N is the total number of neighboring cells queued for the i-th indicator, and n is the ranking number of the i-th indicator;

[0096] According to the weight values and scores of each indicator item, calculate the total score according to the following formula;

[0097] X 总分 =∑X i *i 权重

[0098] Determine the noise floor impact ranking of each neighboring cell according to the total score corresponding to each neighboring cell.

[0099] A further method of the present invention can determine the more accurate noise floor impact of neighboring cells on the main coverage cell by queuing and calculating the weights of associated indicator data.

[0100] In the further description of the above method, it is mainly an explanatory description of the processing process of determining the planned uplink resource reservation ratio of the first network slice according to the uplink rate peak, the initial uplink resource reservation ratio, and the uplink code rate demand value of the test device placed in the first network slice, as follows:

[0101] Determine the planned uplink resource reservation ratio of the first network slice according to the uplink rate peak, the initial uplink resource reservation ratio, and the uplink code rate demand value of the test device placed in the first network slice by using the reservation ratio calculation formula;

[0102] The reservation ratio calculation formula includes:

[0103] Ntest=Scam / Smax×Nmax;

[0104] Among them, Ntest is the planned uplink resource reservation ratio, Scam is the uplink code rate demand value, Smax is the uplink rate peak, and Nmax is the initial uplink resource reservation ratio.

[0105] In this regard, it should be noted that in the present invention, during the configuration process of the network slice, this planned uplink resource reservation ratio can be directly used as the uplink resource reservation ratio of the network slice, or can be adjusted as the uplink resource reservation ratio of the network slice.

[0106] In the further description of the above method, it mainly explains the processing procedure of determining the uplink resource reservation ratio of the first network slice by performing uplink packet filling tests on the test devices in the primary coverage cell according to the planned uplink resource reservation ratio, which is specifically as follows:

[0107] Configure the reservation ratio of the first network slice as the planned uplink resource reservation ratio, and configure the maximum resource occupancy ratio as the planned uplink resource reservation ratio;

[0108] Perform uplink packet filling tests on the test devices in the primary coverage cell, and evaluate the maximum rate that can be used when the resource occupancy ratio of the user terminals of the first network slice is the planned uplink resource reservation ratio. When it is determined that the rate reaches the uplink code rate requirement value, record the planned uplink resource reservation ratio as the uplink resource reservation ratio of the first network slice;

[0109] If the rate does not reach the uplink code rate requirement value, increase the planned uplink resource reservation ratio by a preset second step length, and make the same numerical adjustment to the reservation ratio and the maximum resource occupancy ratio of the first network slice until the rate reaches the uplink code rate requirement value, and record the current configuration value as the uplink resource reservation ratio of the first network slice.

[0110] In this regard, it should be noted that in the present invention, the reservation ratio rRMPolicyMinRatio of the first network slice is configured as Ntest (since the configuration supported by the network management is an integer multiple of 1%, the actual configuration of Ntest needs to be rounded up), and the maximum resource occupancy ratio rRMPolicyMaxRatio is also Ntest. At this time, performing uplink packet filling tests on the test devices in the primary coverage cell can evaluate the maximum rate that can be used when the resource occupancy ratio of the user terminals of the first network slice is Ntest, ensuring that the rate reaches the Scam value. At this time, record the final configuration value as Nf.

[0111] In the extremely rare case where the Scam rate requirement is not met, the Ntest value is increased in steps of 1% and the same configuration adjustment is made to rRMPolicyMinRatio and rRMPolicyMaxRatio until the Scam rate requirement is stably reached. At this time, record the final configuration value as Nf, and record the noise floor value at this time as Bn. Then configure rRMPolicyMinRatio of the first network slice as Nf and rRMPolicyMaxRatio as empty to complete the configuration of the reservation ratio parameters of the first network slice.

[0112] The further method of the present invention calculates by combining on-site tests of the primary coverage cell to obtain the uplink resource reservation ratio of the network slice of the primary coverage cell, realizing the reasonable configuration of the cell network slice.

[0113] An embodiment of the present invention provides a wireless network slice resource reservation display system. Refer to Figure 2 , the system includes:

[0114] A first camera, residing on a first network slice of the main coverage cell, where the first network slice is configured with an uplink resource reservation ratio; and is used to send the collected video signal to the base station according to the reserved resources determined by the uplink resource reservation ratio when the normally configured uplink resources are insufficient; wherein, the configured uplink resource reservation ratio is determined based on the wireless network slice resource reservation analysis method described in any one of the above claims 1-5.

[0115] A second camera, residing on a second network slice of the main coverage cell, where the second network slice is not configured with an uplink resource reservation ratio; and is used to send the collected video signal to the base station after waiting for sufficient uplink resources when the normally configured uplink resources are insufficient.

[0117] A base station, used to upload the video signals collected by the first camera and the second camera to the cloud platform through the core network.

[0118] A cloud platform, used to distribute the video signals collected by the first camera and the second camera to the demonstration terminal.

[0119] A demonstration terminal, used to display the effects of the video signals collected by the first camera and the second camera; wherein, the video signal of the second camera displayed by the demonstration terminal is stuck, and the video signal of the first camera displayed is smooth.

[0120] In the present invention, the first or second camera can be an Internet of Things camera with a 5G SIM card or in the form of a camera plus a 5G CPE. After the first or second camera collects the on-site video signal, it is uploaded back to the base station through 5G uplink and then back to the cloud platform through the core network element. The cloud platform distributes it to the demonstration terminal through the downlink. The demonstration terminal accesses the cloud platform through a fixed network or a wireless network, and it is necessary to ensure the stability of the downlink bandwidth of the demonstration terminal.

[0121] This display system involves a total of 2 wireless slices. The first network slice is configured with a wireless resource reservation ratio to ensure the stability of the uplink backhaul bandwidth of the first camera. The second network slice is not configured with wireless resource reservation. The packet filling terminal and the second camera reside on the second network slice. When the packet filling terminal performs a packet filling test, the second camera is stuck, and the first camera is not stuck. In this way, the bandwidth guarantee effect of slice reservation is demonstrated, providing a demonstration for the video backhaul service requirements.

[0122] In the present invention, according to Figure 2 the two network slice requirements, the first network slice NSSAI is configured, and the slice NSSAI of the SIM1 card is adjusted to correspond thereto. The first network slice 1 needs to be configured with a separate slice NSSAI, and the uplink resource reservation ratio is preferentially configured according to the upper limit of the resources preferentially reserved by the cell that can be configured, and the result of the configured ratio is recorded as Nmax. Since the second network slice is used for packet filling and will preempt the cell resources, resulting in a poor experience of the resident terminals in the slice, it is necessary to consider whether it is necessary to isolate the impact on the real services in the existing network. If the impact of packet filling isolation does not need to be considered in the display area, the first network slice can be co-located with the ordinary ToC slice and share the ordinary slice NSSAI; if the impact of packet filling isolation needs to be considered, the second network slice needs to be configured with an independent NSSAI, and the upper limit of the resource occupancy of the second network slice is configured.

[0123] In addition, before the packet filling terminal performs an uplink packet filling test in the main coverage cell, the base station also needs to adjust the logical channel priorities MLCP of the first network slice and the second network slice to determine that the user terminals (SIM1 / SIM2 / SIM3) resident in each network slice have equal scheduling permissions.

[0124] The wireless network slice resource reservation display system provided by the present invention can intuitively display the bandwidth effect of the slice resource reservation ratio through devices such as a high-definition camera.

[0125] Figure 3 The structure diagram of a wireless network slice resource reservation analysis device provided by the present invention is shown. Refer to Figure 3 and the device includes a configuration module 31, a determination module 32, a calculation module 33 and an analysis module 34, where:

[0126] The configuration module 31 is used to configure the first network slice for the main coverage cell and configure an initial uplink resource reservation ratio for the first network slice;

[0127] The determination module 32 is used to determine the noise floor impact sorting of each neighboring cell on the main coverage cell, and determine the uplink rate peak value of the first network slice according to the uplink packet filling test of the test terminals in each neighboring cell;

[0128] The calculation module 33 is used to determine the planned uplink resource reservation ratio of the first network slice according to the uplink rate peak value, the initial uplink resource reservation ratio and the uplink code rate requirement value of the test equipment placed in the first network slice;

[0129] The analysis module 34 is used to perform an uplink packet filling test on the test equipment in the main coverage cell according to the planned uplink resource reservation ratio to determine the uplink resource reservation ratio of the first network slice.

[0130] In the further description of the above device, the determining module is specifically configured to:

[0131] Obtain the background noise data of the primary coverage cell, and predict the uplink background noise peak value of the primary coverage cell according to the background noise data;

[0132] Obtain the measured field strength of each neighboring cell, the number of handovers between each neighboring cell and the primary coverage cell, and the uplink PRB utilization rate;

[0135] Based on the background noise impact ranking of each neighboring cell, starting from the neighboring cell with the greatest impact, find the handover edge between the neighboring cell and the primary coverage cell, and perform an uplink packet filling test when the test terminal just occupies the neighboring cell. Gradually increase the packet filling rate at a preset first step size until the background noise of the primary coverage cell reaches the uplink background noise peak value;

[0136] When the packet filling rate is increased to the rate peak value of the neighboring cell with the greatest impact and the background noise of the primary coverage cell has not reached the uplink background noise peak value of the primary coverage cell, then make other neighboring cells continue to perform the uplink packet filling test in sequence until the background noise of the primary coverage cell reaches the uplink background noise peak value of the primary coverage cell;

[0137] After the background noise of the primary coverage cell reaches the uplink background noise peak value, perform an uplink rate test on the first network slice of the primary coverage cell, and use the peak value that can be reached as the uplink rate peak value of the first network slice.

[0138] In the further description of the above device, during the process of the determining module determining the background noise impact ranking of each neighboring cell according to the measured field strength of each neighboring cell, the number of handovers between each neighboring cell and the primary coverage cell, and the correlation coefficient between the background noise of the primary coverage cell and the uplink PRB utilization rate of each neighboring cell, it is specifically configured to:

[0139] Arrange the actual values of the measured field strength of each neighboring cell, the number of handovers between each neighboring cell and the primary coverage cell, and the correlation coefficient between the background noise of the primary coverage cell and the uplink PRB utilization rate of each neighboring cell in descending order according to the degree of superiority;

[0140] Calculate the score of each index of each neighboring cell. The neighboring cell with the index ranked first gets 100 points, the neighboring cell with the index ranked last gets 0 points, and for each neighboring cell in the middle, it is calculated respectively according to the following formula:

[0141]

[0142] Among them, X i is the score of the i-th indicator of a certain neighboring cell, N is the total number of queuing neighboring cells of the i-th indicator, and n is the ranking order number of the i-th indicator;

[0143] According to the weight values and scores of each indicator item, the total score is calculated according to the following formula;

[0144] X 总分 = ∑X i *i 权重

[0145] Determine the noise floor impact ranking of each neighboring cell according to the total score corresponding to each neighboring cell.

[0146] In the further description of the above device, the calculation module is specifically used for:

[0147] According to the peak uplink rate, the initial uplink resource reservation ratio, and the uplink code rate demand value of the test device placed in the first network slice, use the reservation ratio calculation formula to determine the planned uplink resource reservation ratio of the first network slice;

[0148] The reservation ratio calculation formula includes:

[0149] Ntest = Scam / Smax × Nmax;

[0150] Among them, Ntest is the planned uplink resource reservation ratio, Scam is the uplink code rate demand value, Smax is the peak uplink rate, and Nmax is the initial uplink resource reservation ratio.

[0152] Configure the reservation ratio of the first network slice as the planned uplink resource reservation ratio, and configure the maximum resource occupancy ratio as the planned uplink resource reservation ratio;

[0153] Perform an uplink packet filling test on the test device in the main coverage cell, evaluate the maximum rate that can be used when the resource occupancy ratio of the user terminal of the first network slice is the planned uplink resource reservation ratio, and when it is determined that the rate reaches the uplink code rate demand value, record the planned uplink resource reservation ratio as the uplink resource reservation ratio of the first network slice;

[0154] If the rate does not reach the uplink code rate requirement value, it is planned to increase the reserved proportion of uplink resources by a preset second step length, and make the same numerical adjustment to the reserved proportion and the maximum resource occupancy proportion of the first network slice until the rate reaches the uplink code rate requirement value, and record the current configuration value as the reserved proportion of uplink resources of the first network slice.
