Description

Technical Field

[0001] This application relates to the technical field of CPE management, and more specifically, to a CPE network transmission management method and device for a 5G smart park. Background Art

[0002] In a 5G smart park, 5G transmission needs to meet the requirements of high bandwidth, low latency, and a large number of connections. However, there may be problems with signal coverage in the actual operation of a 5G smart park. Smart parks usually have complex building structures and may have many obstacles, such as high-rise buildings and underground areas. Due to the unstable signal in these areas, it may affect the performance of the CPE (Customer Premises Equipment). As a customer-premises device, the CPE is responsible for converting 5G signals into local networks. Therefore, signal coverage and stability are crucial. At the same time, in the case of high-density device connections in a 5G smart park, there may be a large number of IoT devices, cameras, sensors, etc. in the park, and capacity bottlenecks may occur.

[0003] Patent CN116886541B (application number: CN202310985279.2) provides a service broadband 5G CPE protection and bandwidth real-time allocation method, which is used for the real-time detection and elastic allocation of the broadband bandwidth of the target line. The method includes: the detection end responds to the usage status of the broadband bandwidth in the target line. When it detects that the broadband bandwidth is being used, the detection end detects whether there is a fault in the optical cable fiber or optical transmission device of the target line; if there is a fault, the detection end controls the service broadband user end port of the target line to be connected from the service port of the optical transmission device to the service port of the CPE device, and sends the fault information to the CPE device. The CPE device is enabled to pass through the service broadband channel of the user plane function from the base station to the 5G core network, and the service broadband is dredged by the user plane function of the 5G core network, realizing real-time detection and switching processing and elastic allocation of broadband bandwidth, reducing the impact caused by faults, and ensuring the smoothness of the service broadband. The method in Patent CN116886541B provides a real-time bandwidth detection and surplus algorithm based on location information to solve the problem of low network resource utilization, improving the utilization rate of bandwidth resources and effectively reducing the allocation error rate. However, in the method of Patent CN116886541B, the scheme depends on location information to dynamically allocate bandwidth. However, in a complex park environment (such as indoors and areas with dense metal structures), the 5G positioning accuracy may drop significantly (usually the 5G indoor positioning accuracy is about 1-3 meters, and the millimeter wave scenario may be worse). In the method of Patent CN116886541B, when the positioning error exceeds the tolerance range of the algorithm, it may cause the bandwidth allocation to deviate from the actual demand. For example, high-bandwidth resources may be wrongly allocated to low-demand areas, exacerbating resource waste. Summary of the Invention

[0031] As used in the specification and appended claims of the present application, the term "if" can be interpreted as "when", "once", "in response to determining", or "in response to detecting" depending on the context. Similarly, the phrase "if determined" or "if detecting [the described condition or event]" can be interpreted as meaning "once determined", "in response to determining", "once detecting [the described condition or event]", or "in response to detecting [the described condition or event]" depending on the context.

[0032] In addition, in the description of the specification and appended claims of the present application, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0033] The reference to "one embodiment" or "some embodiments" or the like described in the specification of the present application means that a specific feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0034] In the prior art, bandwidth is dynamically allocated depending on location information. However, in complex campus environments (such as indoor areas and areas with dense metal structures), the 5G positioning accuracy may drop significantly (usually the 5G indoor positioning accuracy is about 1 - 3 meters, and the millimeter-wave scenario may be even worse). When the positioning error exceeds the tolerance range of the algorithm, it may lead to bandwidth allocation deviating from the actual demand. For example, high-bandwidth resources may be wrongly allocated to low-demand areas, further exacerbating resource waste.

[0035] For the above reasons, the embodiments of the present application provide a CPE network transmission management method for a 5G smart campus. This method includes: obtaining the device identifiers of multiple communication devices in the 5G smart campus network through the 5G core network; where the device identifier is used to identify whether the communication device is a CPE device or a mobile communication device; when the device identifier is a CPE device, allocating bandwidth to the CPE device based on the location information and bandwidth requirements of the CPE device recorded by the 5G core network; when the device identifier is a mobile communication device, obtaining the first location information of the mobile communication device, and dynamically determining the bandwidth allocation strategy of the mobile communication device among multiple CPE devices according to the first location information of the mobile communication device, and allocating bandwidth to the mobile communication device according to the bandwidth allocation strategy; where the first location information is the location information obtained through 5G positioning or GNSS positioning. In the embodiments of the present application, it is possible to determine whether it is necessary to obtain the location information of the network device through positioning according to the type of the network device, and allocate bandwidth to the network device according to the location information of the network device, improving the bandwidth allocation speed and allocation accuracy for different types of network devices, making the bandwidth allocation more in line with the actual demand, and improving the allocation effect of bandwidth resources.

[0036] In some scenarios, a CPE network transmission management method for a 5G smart campus in the embodiments of the present application can be applied to network allocation in a 5G smart campus, capable of efficiently allocating bandwidth to different network devices in a 5G smart campus, and improving the network allocation efficiency for CPE devices and mobile communication devices with relatively fixed locations.

[0037] The following specifically describes a CPE network transmission management method for a 5G smart campus provided by the embodiments of the present application with specific examples.

[0038] Figure 1 It is a schematic flowchart of the first CPE network transmission management method for a 5G smart campus provided by the embodiments of the present application. As Figure 1 shown, this method includes S110 to S120, and the following specifically describes S110 to S120.

[0039] S110. Obtain the device identifiers of multiple communication devices in the 5G smart campus network through the 5G core network. Among them, the device identifier is used to identify whether the communication device is a CPE device or a mobile communication device.

[0040] In the embodiments of the present application, in order to manage the network allocation of multiple communication devices, the device identifiers of multiple communication devices within the 5G smart park network can be obtained through the 5G core network first. The device identifier is used to identify whether the communication device is a CPE device or a mobile communication device. The position of the CPE device is relatively fixed, and the mobile communication device is often a communication device during movement. Therefore, the CPE device or the mobile communication device can be distinguished, and network resources can be allocated to the CPE device or the mobile communication device according to the position movement characteristics of the CPE device or the mobile communication device.

[0041] Exemplarily, the mobile communication device can be an electronic device using the 5G network, such as an AGV cart, a mobile phone, a drone, etc.

[0042] S120. When the device identifier is a CPE device, bandwidth is allocated to the CPE device based on the location information and bandwidth requirements of the CPE device recorded by the 5G core network. When the device identifier is a mobile communication device, the first location information of the mobile communication device is obtained, and the bandwidth allocation policy of the mobile communication device among multiple CPE devices is dynamically determined according to the first location information of the mobile communication device, and bandwidth is allocated to the mobile communication device according to the bandwidth allocation policy. Wherein, the first location information is the location information obtained through 5G positioning or GNSS positioning.

[0043] After obtaining the device identifiers of multiple communication devices, when the device identifier is a CPE device, since the position of the CPE device is relatively fixed, bandwidth can be allocated to the CPE device based on the location information and bandwidth requirements of the CPE device recorded by the 5G core network, which reduces the time for actively obtaining the location information of the CPE device and also avoids the positioning error that may be caused by actively obtaining the location information of the CPE device, thereby improving the efficiency of network resource allocation for the CPE device.

[0044] After obtaining the device identifiers of multiple communication devices, when the device identifier is a mobile communication device, the first location information of the mobile communication device can be obtained first, and then the bandwidth allocation policy of the mobile communication device among multiple CPE devices can be dynamically determined according to the first location information of the mobile communication device, and bandwidth is allocated to the mobile communication device according to the bandwidth allocation policy, realizing the network bandwidth allocation for multiple CPE devices.

[0045] When obtaining the first location information of the mobile communication device, the first location information can be the location information obtained through 5G positioning or GNSS positioning.

[0046] The beneficial effects of the above implementation method are as follows: it can determine whether it is necessary to obtain the location information of the network device through positioning according to the category of the network device, and allocate bandwidth to the network device according to the location information of the network device, improving the bandwidth allocation speed and accuracy for different types of network devices, making the bandwidth allocation more in line with the actual needs, and improving the allocation effect of bandwidth resources.

[0047] Figure 2 FIG. is a schematic flowchart of a second 5G smart park CPE network transmission management method provided by an embodiment of the present application. As Figure 2 shown, this method further includes S210 to S220, and the following is a specific description of S210 to S220.

[0048] S210: Obtain the actual bandwidth value of the mobile communication device, and determine the bandwidth difference between the bandwidth allocation value and the actual bandwidth value of the mobile communication device as the bandwidth deviation value.

[0049] In the embodiment of the present application, in order to further improve the accuracy of network resource allocation for the mobile communication device, the actual bandwidth value of the mobile communication device can be obtained. The actual bandwidth value of the mobile communication device is the network state of the mobile communication device in the current state. Furthermore, the bandwidth difference between the bandwidth allocation value and the actual bandwidth value of the mobile communication device can be determined as the bandwidth deviation value. The bandwidth allocation value is the theoretical bandwidth of the network allocated by the 5G core network to the mobile communication device, and the bandwidth deviation value characterizes the error between the theoretical value and the actual value of the bandwidth allocation for the mobile communication device.

[0050] It should be noted that when the bandwidth difference between the bandwidth allocation value and the actual bandwidth value of the mobile communication device is larger, it indicates that the bandwidth allocation effect of the mobile communication device is worse.

[0051] S220: When the bandwidth deviation value is greater than the preset bandwidth deviation value, the 5G core network obtains the second location information of the mobile communication device through the CPE device, and dynamically determines the comprehensive bandwidth allocation strategy of the mobile communication device among multiple CPE devices based on the first location information and the second location information of the mobile communication device, and allocates bandwidth to the mobile communication device according to the comprehensive bandwidth allocation strategy. Among them, the second location information is the location information obtained through UWB or Wi-Fi fingerprint positioning.

[0052] After obtaining the bandwidth deviation value, when the bandwidth deviation value is greater than the preset bandwidth deviation value, it indicates that the bandwidth allocation of the mobile communication device has not achieved the expected bandwidth allocation effect. The 5G core network can obtain the second location information of the mobile communication device through the CPE device, and the second location information of the mobile communication device is the more accurate location information obtained through the CPE device.

[0053] After obtaining the first location information and the second location information of the mobile communication device, the comprehensive bandwidth allocation strategy of the mobile communication device among multiple CPE devices can be dynamically determined based on the first location information and the second location information of the mobile communication device, and then the bandwidth can be allocated to the mobile communication device according to the comprehensive bandwidth allocation strategy.

[0054] Exemplarily, when determining the comprehensive bandwidth allocation strategy of the mobile communication device among multiple CPE devices, the location of the mobile communication device can be comprehensively determined by multiple CPE devices, and the comprehensive bandwidth allocation strategy of the mobile communication device among multiple CPE devices can be determined according to the power and the bandwidth allocation strategy.

[0055] Exemplarily, the second location information can be the location information obtained by UWB (Ultra Wide Band) or Wi-Fi fingerprint positioning. The positioning accuracy of the location information obtained by UWB and Wi-Fi fingerprint positioning is higher than that of the location information obtained by 5G positioning or GNSS positioning. Furthermore, the second location information with higher positioning accuracy can be used to further improve the network allocation effect on the mobile communication device.

[0056] The beneficial effect of the above implementation is that when the bandwidth allocation of the mobile communication device does not achieve the expected bandwidth allocation effect, the 5G core network obtains the second location information of the mobile communication device through the CPE device, and improves the network allocation effect and communication quality of the mobile communication device according to the second location information of the mobile communication device, thereby improving the utilization effect of network resources.

[0057] In some implementations, the above method further includes: obtaining the location information of the CPE device. When the location information of the CPE device is outdoor, the first bandwidth allocation strategy of the mobile communication device among multiple CPE devices is dynamically determined based on the first location information of the mobile communication device, and the bandwidth is allocated to the mobile communication device according to the first bandwidth allocation strategy. When the location information of the CPE device is indoor, the second bandwidth allocation strategy of the mobile communication device among multiple CPE devices is dynamically determined based on the second location information of the mobile communication device, and the bandwidth is allocated to the mobile communication device according to the second bandwidth allocation strategy.

[0058] Since the positioning accuracies of the location information of the mobile communication device obtained through 5G positioning or GNSS positioning and the location information of the mobile communication device obtained through UWB and Wi-Fi fingerprint positioning are different, and the positioning accuracy through 5G positioning or GNSS positioning is relatively high in the outdoor environment compared to the indoor environment, while CPE devices are generally deployed in the indoor environment, and the positioning accuracy of UWB and Wi-Fi fingerprint positioning is relatively high in the indoor environment. Therefore, when detecting the location of the mobile communication device, the location information of the CPE device can be obtained, and the location information of the CPE device is used to indicate whether the CPE device is located indoors or outdoors.

[0059] Exemplarily, the location information of the CPE device can be registered in the 5G core network when the CPE device is configured.

[0060] After obtaining the location information of the CPE device, when the location information of the CPE device is outdoor, since the first location information obtained through 5G positioning or GNSS positioning is relatively accurate, and due to reasons such as the small number of CPE devices in the outdoor environment, the low deployment density of outdoor CPE devices, and the possible large distance between outdoor CPE devices and the mobile communication device, it may lead to insufficient positioning accuracy of the mobile communication device through the CPE device. At this time, the first bandwidth allocation strategy of the mobile communication device among multiple CPE devices can be dynamically determined through the first location information of the mobile communication device, and the bandwidth is allocated to the mobile communication device according to the first bandwidth allocation strategy, so as to perform network allocation for the mobile communication device through the first location information with higher positioning accuracy outdoors.

[0061] After obtaining the location information of the CPE device, when the location information of the CPE device is indoor, since the location accuracy of the mobile communication device obtained through 5G positioning or GNSS positioning in the indoor environment is insufficient, due to reasons such as the large number of CPE devices in the indoor environment, the high deployment density of indoor CPE devices, and the relatively short distance between outdoor CPE devices and the mobile communication device, it is possible to preferentially use the CPE device to locate the mobile communication device. Furthermore, the second bandwidth allocation strategy of the mobile communication device among multiple CPE devices can be dynamically determined through the second location information of the mobile communication device, and the bandwidth is allocated to the mobile communication device according to the second bandwidth allocation strategy, so as to perform network allocation for the mobile communication device through the second location information with higher positioning accuracy indoors.

[0062] The beneficial effect of the above implementation method is that through the location information of the CPE device used to indicate whether the CPE device is located indoors or outdoors, it is possible to allocate bandwidth to the mobile communication device according to the location information with higher positioning accuracy of the mobile communication device according to different indoor or outdoor scenarios, improving the effect of bandwidth allocation for the mobile communication device.

[0063] Figure 3 This is a schematic flowchart of the third CPE network transmission management method for a 5G smart campus provided by an embodiment of this application. As Figure 3 shown, the above method further includes S310 to S320, and the following is a specific description of S310 to S320.

[0064] S310: When the location information of the CPE device is indoor, determine the difference between the bandwidth deviation values before and after the mobile communication device allocates bandwidth according to the second bandwidth allocation strategy, and use it as the first bandwidth deviation value change value.

[0065] After obtaining the second bandwidth allocation strategy, when the location information of the CPE device is indoor, it is possible to determine the difference between the bandwidth deviation values before and after the mobile communication device allocates bandwidth according to the second bandwidth allocation strategy, and use it as the first bandwidth deviation value change value. The first bandwidth deviation value change value can characterize the network impact degree of allocating bandwidth to the mobile communication device according to the second bandwidth allocation strategy.

[0066] It should be noted that when the bandwidth deviation value before and after the mobile communication device allocates bandwidth according to the second bandwidth allocation strategy is greater than 0, it indicates that the bandwidth allocation effect of the mobile communication device is optimized; when the bandwidth deviation value before and after the mobile communication device allocates bandwidth according to the second bandwidth allocation strategy is less than 0, it indicates that the bandwidth allocation effect of the mobile communication device deteriorates.

[0067] S320: When the first bandwidth deviation value change value is less than the preset bandwidth deviation value change value, the 5G core network determines the corrected second location information of the mobile communication device through multiple CPE devices, dynamically determines the corrected second bandwidth allocation strategy of the mobile communication device among multiple CPE devices according to the corrected second location information of the mobile communication device, and allocates bandwidth to the mobile communication device according to the corrected second bandwidth allocation strategy.

[0068] After obtaining the first bandwidth deviation value change value, when the first bandwidth deviation value change value is less than the preset bandwidth deviation value change value, it indicates that the optimization of the bandwidth allocation for the mobile communication device is not good. Since the location information of the CPE device is indoor, at this time, the 5G core network can determine the corrected second location information of the mobile communication device through multiple CPE devices to further improve the accuracy of positioning the location of the mobile communication device.

[0069] After obtaining the corrected second position information, the corrected second bandwidth allocation policy of the mobile communication device among multiple CPE devices can be dynamically determined based on the corrected second position information of the mobile communication device, and the bandwidth of the mobile communication device can be allocated according to the corrected second bandwidth allocation policy to improve the network allocation effect of the mobile communication device according to the corrected second bandwidth allocation policy.

[0070] The beneficial effect of the above implementation manner is that by using the change value of the first bandwidth deviation value to evaluate the position information of the CPE device as indoor and the network allocation status of the mobile communication device, the corrected second position information of the mobile communication device can be determined through multiple CPE devices, and the network allocation of the mobile communication device can be optimized according to the corrected second position information, thereby improving the network allocation effect of the mobile communication device.

[0071] In some implementation manners, Figure 4 FIG. is a schematic flowchart of a fourth CPE network transmission management method for a 5G smart park provided by an embodiment of the present application. As Figure 4 shown, the above method further includes S410 to S430, which will be specifically described below.

[0072] S410: Determine the difference between the bandwidth deviation values before and after the mobile communication device allocates bandwidth according to the corrected second bandwidth allocation policy as the change value of the second bandwidth deviation value.

[0073] After obtaining the corrected second bandwidth allocation policy, the network allocation effect according to the corrected second bandwidth allocation policy can be further evaluated. The difference between the bandwidth deviation values before and after the mobile communication device allocates bandwidth according to the corrected second bandwidth allocation policy can be determined as the change value of the second bandwidth deviation value, and then the network allocation effect of the mobile communication device allocating bandwidth according to the corrected second bandwidth allocation policy can be evaluated based on the change value of the second bandwidth deviation value.

[0074] S420: When the change value of the second bandwidth deviation value is less than the preset change value of the bandwidth deviation value, determine the corrected position information of the CPE device based on the position information of the CPE device, the actual bandwidth values corresponding to the mobile communication device before and after allocating bandwidth according to the second bandwidth allocation policy, and the actual bandwidth values corresponding to the mobile communication device before and after allocating bandwidth according to the corrected second bandwidth allocation policy.

[0075] After obtaining the change value of the second bandwidth deviation value, when the change value of the second bandwidth deviation value is less than the preset change value of the bandwidth deviation value, it indicates that the network allocation effect on the mobile communication device by allocating bandwidth according to the corrected second bandwidth allocation strategy is not good. At this time, it may be due to the low position accuracy of the CPE device itself that leads to the poor network allocation effect on the mobile communication device.

[0076] When the low position accuracy of the CPE device itself leads to a poor network allocation effect on the mobile communication device, the corrected position information of the CPE device can be determined according to the position information of the CPE device, the actual bandwidth values corresponding to the mobile communication device before and after allocating bandwidth according to the second bandwidth allocation strategy, and the actual bandwidth values corresponding to the mobile communication device before and after allocating bandwidth according to the corrected second bandwidth allocation strategy, so as to correct the corrected position information of the CPE device.

[0077] Exemplarily, when correcting the corrected position information of the CPE device, the corrected position information of the CPE device can be corrected according to the relationship model between the bandwidth change of the mobile communication device and the position of the CPE device. The relationship model between the bandwidth change of the mobile communication device and the position of the CPE device can be obtained through training with labeled data. The labeled data can include the labeled position information of the CPE device, the actual bandwidth values corresponding to the mobile communication device before and after allocating bandwidth according to the bandwidth allocation strategy, and the actual bandwidth values corresponding to the mobile communication device before and after allocating bandwidth according to the corrected bandwidth allocation strategy.

[0078] S430. The 5G core network determines the third position information of the mobile communication device through the corrected position information of the CPE device, dynamically determines the third bandwidth allocation strategy of the mobile communication device among multiple CPE devices through the corrected position information of the CPE device and the third position information of the mobile communication device, and allocates bandwidth to the mobile communication device according to the third bandwidth allocation strategy.

[0079] After obtaining the corrected position information of the CPE device, the 5G core network further determines the third position information of the mobile communication device through the corrected position information of the CPE device, dynamically determines the third bandwidth allocation strategy of the mobile communication device among multiple CPE devices through the corrected position information of the CPE device and the third position information of the mobile communication device, and allocates bandwidth to the mobile communication device according to the third bandwidth allocation strategy, so as to optimize the bandwidth allocation effect on the mobile communication device through the third bandwidth allocation strategy.

[0080] When optimizing the bandwidth allocation effect on the mobile communication device, the bandwidth allocation effect on the mobile communication device can be optimized through the corrected position information of the CPE device in S420.

[0081] The beneficial effects of the above implementation method are that when the position accuracy of the CPE device itself is not high, resulting in poor network allocation effect for the mobile communication device, the position of the CPE device itself is corrected, and the bandwidth allocation for the mobile communication device is optimized according to the corrected position of the CPE device, improving the broadband allocation effect for the mobile communication device.

[0082] Another beneficial effect of the above implementation method is that when optimizing the bandwidth allocation effect for the mobile communication device, the third position information of the mobile communication device is determined through the corrected position information of the CPE device, and the bandwidth allocation effect for the mobile communication device is optimized through the corrected position information of the CPE device, ensuring the network optimization effect for the mobile communication device.

[0083] In some implementation methods, in the above method, the preset bandwidth deviation value change value can be determined through S421 to S422:

[0084] S421. Obtain the key service occupancy ratio of the mobile communication device and the network idle capacity ratio value of the current 5G core network.

[0085] When determining whether the network optimization effect of the mobile communication device meets the standard, the key service occupancy ratio of the mobile communication device and the network idle capacity ratio value of the current 5G core network can be obtained. The key service occupancy ratio represents the importance of the network carried by the network of the mobile communication device, and the network idle capacity ratio value of the current 5G core network represents the idle bandwidth value of the 5G core network.

[0086] S422. When the key service occupancy ratio of the mobile communication device is greater than or equal to the preset key service occupancy ratio, use the difference between 1 and the key service occupancy ratio multiplied by the reference bandwidth deviation value change value as the preset bandwidth deviation value change value. When the key service occupancy ratio of the mobile communication device is less than the preset key service occupancy ratio and the network idle capacity ratio value is greater than or equal to the preset network idle capacity ratio value, use the sum of 1 and the network idle capacity ratio value multiplied by the reference bandwidth deviation value change value as the preset bandwidth deviation value change value.

[0087] After obtaining the key service occupancy ratio of the mobile communication device, when the key service occupancy ratio of the mobile communication device is greater than or equal to the preset key service occupancy ratio, it indicates that the network priority of the mobile communication device is relatively high. At this time, the difference between 1 and the key service occupancy ratio multiplied by the reference bandwidth deviation value change value can be used as the preset bandwidth deviation value change value, so as to reduce the preset bandwidth deviation value change value when the network priority of the mobile communication device is relatively high, improve the value of the preset bandwidth deviation value change value for evaluating the network optimization of the mobile communication device, and ensure the network optimization effect for the mobile communication device of the key service.

[0088] After obtaining the critical business proportion value of the mobile communication device, when the critical business proportion value of the mobile communication device is less than the preset critical business proportion value, and when the network idle capacity proportion value is greater than or equal to the preset network idle capacity proportion value, it means that the network priority of the mobile communication device is not high, and the current 5G core network has more idle broadband resources. At this time, the sum of 1 and the network idle capacity proportion value multiplied by the baseline bandwidth deviation value change value can be used as the preset bandwidth deviation value change value to increase the value of the preset bandwidth deviation value change, thereby reducing the number of optimizations of the 5G core network when the network priority of the mobile communication device is not high and the idle broadband resources of the 5G core network are more, thereby reducing the resource consumption of the 5G core network.

[0089] The beneficial effect of the above-mentioned implementation method is that when the network priority of the mobile communication device is higher, the difference between 1 and the critical business proportion value multiplied by the baseline bandwidth deviation value change value can be used as the preset bandwidth deviation value change value, thereby ensuring the network optimization effect on the mobile communication device for critical business.

[0090] The beneficial effect of the above-mentioned implementation method is that when the critical business proportion of the mobile communication device is less than the preset critical business proportion, and when the network idle capacity proportion is greater than or equal to the preset network idle capacity proportion, by multiplying the sum of 1 and the network idle capacity proportion by the change value of the reference bandwidth deviation value, the number of optimizations of the 5G core network when the network priority of the mobile communication device is not high and the 5G core network has more idle broadband resources is reduced, thereby reducing the resource consumption of the 5G core network.

[0091] Figure 5 A flow chart of a fifth 5G smart park CPE network transmission management method provided in an embodiment of the present application is as follows: Figure 5 As shown, the above method also includes S510 to S520, and S510 to S520 are described in detail below.

[0092] S510. Obtain delay sensitivity of the mobile communication device through the 5G core network, where the delay sensitivity represents the delay sensitivity of the network communication of the mobile communication device.

[0093] When determining the change value of the preset bandwidth deviation value, the delay sensitivity of the mobile communication device can be obtained through the 5G core network. The delay sensitivity characterizes the delay sensitivity of the network communication of the mobile communication device, and the change value of the preset bandwidth deviation value can be further optimized according to the delay sensitivity of the mobile communication device.

[0094] S520. When the ratio of critical services of a mobile communication device is greater than or equal to a preset critical service ratio, and the latency sensitivity of the mobile communication device is greater than a preset latency sensitivity, adjust the preset bandwidth deviation value change of the mobile communication device by multiplying the difference between 1 and the latency sensitivity by the preset bandwidth deviation value change.

[0095] After obtaining the latency sensitivity of the mobile communication device, when the ratio of critical services of the mobile communication device is greater than or equal to the preset critical service ratio, and the latency sensitivity of the mobile communication device is greater than the preset latency sensitivity, it indicates that the service priority of the mobile communication device is relatively high and the latency sensitivity is relatively large. At this time, the preset bandwidth deviation value change of the mobile communication device can be adjusted by multiplying the difference between 1 and the latency sensitivity by the preset bandwidth deviation value change, so as to reduce the preset bandwidth deviation value change, and the bandwidth optimization effect on the mobile communication device can be improved.

[0096] The beneficial effect of the above implementation method is that when the service priority of the mobile communication device is relatively high and the latency sensitivity is relatively large, by multiplying the difference between 1 and the latency sensitivity by the preset bandwidth deviation value change to reduce the preset bandwidth deviation value change, the bandwidth optimization effect on the mobile communication device with relatively high latency sensitivity can be improved.

[0097] In some implementation methods, the above method further includes: obtaining the maximum device moving speed in the 5G smart park, obtaining the real-time moving speed of the mobile communication device, and adjusting the preset bandwidth deviation value change by the following formula:

[0098]

[0099] where represents Δ p2 represents the adjusted preset bandwidth deviation value change, Δ p1 represents the preset bandwidth deviation value change before adjustment, v represents the real-time moving speed of the mobile communication device, v max represents the maximum moving speed of the mobile communication device.

[0100] The beneficial effect of the above implementation method is that by detecting the real-time moving speed of the mobile communication device and adjusting the preset bandwidth deviation value change according to the real-time moving speed of the mobile communication device, the mobile communication device moving at a high speed can reduce the preset bandwidth deviation value change to increase the adjustment frequency of the bandwidth allocation fast strategy, avoid the bandwidth mismatch of the mobile communication device caused by the high-speed movement of the mobile communication device, and improve the bandwidth allocation effect on the mobile communication device.

[0101] In some implementations, in the above method, the preset moving time period can also be adjusted through S610 to S620. The following is a specific description of S610 to S620.

[0102] S610. Obtain the network idle capacity ratio value of the current 5G core network.

[0103] In the embodiments of the present application, the network idle capacity ratio value of the current 5G core network can be obtained, and the preset moving time period can be adjusted through the network idle capacity ratio value.

[0104] S620. When the network idle capacity ratio value is greater than or equal to the preset network idle capacity ratio value, use the sum of 1 and the network idle capacity ratio value multiplied by the reference preset moving time period as the preset moving time period. Among them, different mobile communication devices correspond to different reference preset moving time periods.

[0105] When adjusting the preset moving time period, when the network idle capacity ratio value is greater than or equal to the preset network idle capacity ratio value, it indicates that the current network idle capacity is large. The sum of 1 and the network idle capacity ratio value multiplied by the reference preset moving time period can be used as the preset moving time period to increase the preset moving time period. Furthermore, the area of the target region for obtaining the network congestion indices corresponding to multiple CPE devices can be increased. Furthermore, by increasing the number of multiple CPE devices for monitoring the network congestion index, the network optimization effect for mobile communication devices can be improved.

[0106] When determining the preset moving time period, different mobile communication devices correspond to different reference preset moving time periods. For example, AGV devices and mobile phones have different reference preset moving time periods. Furthermore, broadband allocation can be performed for AGV devices and mobile phones with different moving speeds, ensuring the broadband allocation effect for AGV devices and mobile phones with different moving speeds.

[0107] The beneficial effect of the above implementation is that when the current network idle capacity is large, the area of the target region for obtaining the network congestion indices corresponding to multiple CPE devices is increased, and by increasing the number of multiple CPE devices for monitoring the network congestion index, the network optimization effect for different mobile devices can be improved.

[0108] In some implementations, the above method further includes: obtaining the target region where the mobile communication device moves within the preset moving time period according to the real-time moving speed, obtaining the network congestion indices corresponding to multiple CPE devices in the target region, and adjusting the preset bandwidth deviation value change value through the following formula:

[0109]

[0110] Wherein, Δ p4 represents the changed value of the preset bandwidth deviation value after adjustment, and Δ p3 represents the changed value of the preset bandwidth deviation value before adjustment. ρ represents the sum of the network congestion indices corresponding to multiple CPE devices in the target area, and ρ total represents the sum of the network congestion indices of all CPE devices in the 5G smart park.

[0111] Exemplarily, when determining the target area where the mobile communication device moves at the real-time moving speed within the preset moving time period, it is possible to determine the area with the mobile communication device as the center and the moving distance of the real-time moving speed of the mobile communication device within the preset moving time period as the radius as the target area.

[0112] The beneficial effect of the above implementation manner is that by determining the target area where the mobile communication device moves at the real-time moving speed within the preset moving time period, obtaining the network congestion indices corresponding to multiple CPE devices in the target area, and combining the sum of the network congestion indices of all CPE devices in the 5G smart park to evaluate the network congestion degree corresponding to multiple CPE devices in the target area, so as to dynamically adjust the changed value of the preset bandwidth deviation value, it is possible to reduce the signaling storm caused by frequent adjustment according to the network congestion degree and improve the effect of network optimization.
