Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of CPE management, and more particularly to a CPE network transmission management method and device for a 5G smart park. BACKGROUND

[0002] In a 5G smart park, 5G transmission needs to meet the requirements of high bandwidth, low delay and large number of connections, but there may be signal coverage problems in the actual work of the 5G smart park. A smart park usually has a complex building structure and may have many obstacles, such as high-rise buildings and underground areas. Due to the unstable problem of signals in these places, the performance of CPE (Customer Premises Equipment) may be affected. CPE is a customer front-end device that is responsible for converting 5G signals into local networks, so signal coverage and stability are critical. At the same time, in the case of high-density device connection in a 5G smart park, there may be a large number of IoT devices, cameras, sensors, etc. in the park, which may cause a capacity bottleneck.

[0003] Patent CN116886541B (application number: CN202310985279.2) provides a service broadband 5GCPE protection and real-time bandwidth allocation method. The method is used for real-time detection and elastic allocation of the broadband bandwidth of the target line. The method comprises: the detection end responds to the use state of the broadband bandwidth in the target line, and when it is detected that the broadband bandwidth is being used, the detection end detects whether the optical cable optical fiber or optical transmission device of the target line has a fault; 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 of 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 switching processing and elastic allocation of the broadband bandwidth, reducing the influence of the fault, and ensuring the smoothness of the service broadband. In the method of patent CN116886541B, in order to solve the problem of low network resource utilization, a real-time bandwidth detection and surplus amount algorithm based on position information is provided, so that the bandwidth resource utilization is improved and the allocation error rate is effectively reduced. However, in the method of patent CN116886541B, the scheme relies on position information to dynamically allocate bandwidth, but in a complex park environment (such as indoors, areas with dense metal structures), the 5G positioning accuracy may be greatly reduced (usually 5G indoor positioning accuracy is about 1-3 meters, and millimeter wave scenarios may be worse). In the method of patent CN116886541B, when the positioning error exceeds the tolerance range of the algorithm, the bandwidth allocation may deviate from the actual demand, for example, high-bandwidth resources are incorrectly allocated to low-demand areas, which may exacerbate resource waste.

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

[0033] The reference in the specification to "one embodiment" or "some embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Thus, the appearance of the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in additional embodiments", etc. in various places throughout the specification is not necessarily all referring to the same embodiment, but means "one or more but not all embodiments", unless otherwise specifically stated. The terms "comprise", "include", "have" and their conjugates mean "including but not limited to", unless otherwise specifically stated.

[0034] In the prior art, bandwidth is dynamically allocated based on location information, but in a complex park environment (such as indoors or areas with dense metal structures), the 5G positioning accuracy can be greatly reduced (typically 5G indoor positioning accuracy is about 1-3 meters, and millimeter wave scenarios can be worse). When the positioning error exceeds the tolerance range of the algorithm, the bandwidth allocation may deviate from the actual demand, for example, high bandwidth resources are incorrectly allocated to low demand areas, which further exacerbates resource waste.

[0035] Based on the above reasons, the embodiments of the present application provide a CPE network transmission management method for a 5G smart park. The method comprises: obtaining device identifiers of a plurality of communication devices in a 5G smart park network through a 5G core network; wherein the device identifier is used to identify that the communication device is a CPE device or a mobile communication device; when the device identifier is a CPE device, recording the location information and bandwidth demand of the CPE device through the 5G core network, and allocating bandwidth to the CPE device; when the device identifier is a mobile communication device, obtaining first location information of the mobile communication device, and dynamically determining a bandwidth allocation strategy for the mobile communication device among a plurality of 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; wherein the first location information is location information obtained through 5G positioning or GNSS positioning. In the embodiments of the present application, it can be determined whether the location information of the network device needs to be obtained through positioning according to the category of the network device, and the network device is allocated bandwidth according to the location information of the network device, which improves the bandwidth allocation speed and accuracy for different types of network devices, makes the bandwidth allocation more in line with the actual demand, and improves the allocation effect of bandwidth resources.

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

[0037] The CPE network transmission management method for a 5G smart park provided by the embodiments of the present application will be described in detail below with specific examples.

[0038] Figure 1 The flowchart of the first CPE network transmission management method for a 5G smart park provided by the embodiments of the present application is shown in Figure 1 S110 to S120, which will be described below.

[0039] S110, obtain device identifiers of a plurality of communication devices in a 5G smart park network through a 5G core network. Wherein the device identifier is used to identify that 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 the multiple communication devices in 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 in the process of movement. Then, the CPE device or the mobile communication device can be distinguished to allocate network resources to the CPE device or the mobile communication device according to the position and movement characteristics of the CPE device or the mobile communication device.

[0041] Exemplarily, the mobile communication device can be an AGV trolley, a mobile phone, a drone, and other electronic devices using a 5G network.

[0042] In S120, when the device identifier is a CPE device, the position information and bandwidth demand of the CPE device recorded through the 5G core network are used to allocate bandwidth to the CPE device. When the device identifier is a mobile communication device, the first position information of the mobile communication device is obtained, and a bandwidth allocation strategy of the mobile communication device among multiple CPE devices is dynamically determined according to the first position information of the mobile communication device. The bandwidth of the mobile communication device is allocated according to the bandwidth allocation strategy. The first position information is position information obtained through 5G positioning or GNSS positioning.

[0043] After obtaining the device identifiers of the multiple communication devices, when the device identifier is a CPE device, the position of the CPE device is relatively fixed. The position information and bandwidth demand of the CPE device recorded through the 5G core network can be used to allocate bandwidth to the CPE device, which reduces the time of actively obtaining the position information of the CPE device and avoids the positioning error caused by actively obtaining the position information of the CPE device, thereby improving the efficiency of network resource allocation to the CPE device.

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

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

[0046] The implementation manner has the beneficial effects that whether the position information of the network device needs to be acquired through positioning can be determined according to the category of the network device, and the network device is allocated bandwidth according to the position information of the network device, the bandwidth allocation speed and the allocation accuracy for different types of network devices are improved, the bandwidth allocation is more in line with actual needs, and the allocation effect of the bandwidth resources is improved.

[0047] Figure 2 A flowchart of a second CPE network transmission management method of a 5G smart park provided by an embodiment of the present application is shown in Figure 2 As shown in the figure, the method further includes S210 to S220, which are specifically described below.

[0048] S210, an actual bandwidth value of the mobile communication device is acquired, and a bandwidth difference value between a bandwidth allocation value of the mobile communication device and the actual bandwidth value is determined as a bandwidth deviation value.

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

[0051] S220, when the bandwidth deviation value is greater than a preset bandwidth deviation value, the 5G core network acquires second position information of the mobile communication device through the CPE device, dynamically determines a comprehensive bandwidth allocation strategy of the mobile communication device between the plurality of CPE devices through the first position information and the second position information of the mobile communication device, and allocates bandwidth to the mobile communication device according to the comprehensive bandwidth allocation strategy. The second position information is position information acquired through UWB or Wi-Fi fingerprint positioning.

[0052] After the bandwidth deviation value is obtained, when the bandwidth deviation value is greater than a preset bandwidth deviation value, it indicates that the bandwidth allocation of the mobile communication device does not achieve the expected bandwidth allocation effect, and the 5G core network can acquire second position information of the mobile communication device through the CPE device, the second position information of the mobile communication device being more accurate position information acquired through the CPE device.

[0053] After obtaining the first location information and the second location information of the mobile communication device, a comprehensive bandwidth allocation strategy of the mobile communication device among the plurality of 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] For example, when determining the comprehensive bandwidth allocation strategy of the mobile communication device among the plurality of CPE devices, the location of the mobile communication device can be determined comprehensively by the plurality of CPE devices, and the comprehensive bandwidth allocation strategy of the mobile communication device among the plurality of CPE devices can be determined according to the power and the bandwidth allocation strategy.

[0055] For example, the second location information can be 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 the location accuracy of the location information obtained by 5G positioning or GNSS positioning, and thus the second location information with higher positioning accuracy can further improve the network allocation effect on the mobile communication device.

[0056] The above-mentioned implementation manner has the beneficial effect 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 the 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 implementation manners, the above-mentioned method further includes: obtaining location information of the CPE device, when the location information of the CPE device is outdoor, a first bandwidth allocation strategy of the mobile communication device among the plurality of 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, a second bandwidth allocation strategy of the mobile communication device among the plurality of 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 accuracy of the position information of the mobile communication device acquired through 5G positioning or GNSS positioning, the position information of the mobile communication device acquired through UWB and Wi-Fi fingerprint positioning is different, and the positioning accuracy through 5G positioning or GNSS positioning is higher in an outdoor case than in an indoor environment, while the CPE device is generally arranged in an indoor environment, and the positioning accuracy of UWB and Wi-Fi fingerprint positioning is higher in an indoor environment. Therefore, when detecting the position of the mobile communication device, the position information of the CPE device can be acquired, and the position information of the CPE device is used to represent that the CPE device is located indoors or outdoors.

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

[0060] After obtaining the position information of the CPE device, when the position information of the CPE device is outdoor, since the first position information acquired through 5G positioning or GNSS positioning is more accurate, and due to the reasons such as that the number of CPE devices is small, the deployment density of the CPE devices is low, and the distance between the CPE devices and the mobile communication device is large in an outdoor environment, the positioning accuracy of the mobile communication device through the CPE device can be insufficient, at this time, the first bandwidth allocation strategy of the mobile communication device between multiple CPE devices can be dynamically determined through the first position information of the mobile communication device, and the bandwidth of the mobile communication device is allocated according to the first bandwidth allocation strategy, so as to perform network allocation on the mobile communication device through the first position information with higher positioning accuracy in an outdoor environment.

[0061] After obtaining the position information of the CPE device, when the position information of the CPE device is indoor, since the positioning accuracy of the mobile communication device acquired through 5G positioning or GNSS positioning in an indoor environment is insufficient, and due to the reasons such as that the number of CPE devices is large, the deployment density of the CPE devices is high, and the distance between the CPE devices and the mobile communication device is close in an indoor environment, the mobile communication device can be preferentially positioned through the CPE device, and then the second bandwidth allocation strategy of the mobile communication device between multiple CPE devices can be dynamically determined through the second position information of the mobile communication device, and the bandwidth of the mobile communication device is allocated according to the second bandwidth allocation strategy, so as to perform network allocation on the mobile communication device through the second position information with higher positioning accuracy in an indoor environment.

[0062] The above-mentioned implementation manner has the beneficial effect that, through the position information of the CPE device used to represent that the CPE device is located indoors or outdoors, the bandwidth of the mobile communication device can be allocated according to the position information with higher positioning accuracy of the mobile communication device according to different indoor or outdoor scenes, and the effect of bandwidth allocation of the mobile communication device is improved.

[0063] Figure 3 A third flowchart of a CPE network transmission management method of a 5G smart park according to an embodiment of the present application is shown in FIG. 3. As shown in FIG. 3, the method further includes S310-S320, which are described below. Figure 3

[0064] S310, when the location information of the CPE device is indoor, determining the difference between the bandwidth deviation value before the mobile communication device allocates bandwidth according to the second bandwidth allocation strategy and the bandwidth deviation value after the mobile communication device allocates bandwidth according to the second bandwidth allocation strategy as a first bandwidth deviation value change value.

[0065] After obtaining the second bandwidth allocation strategy, when the location information of the CPE device is indoor, the difference between the bandwidth deviation value before the mobile communication device allocates bandwidth according to the second bandwidth allocation strategy and the bandwidth deviation value after the mobile communication device allocates bandwidth according to the second bandwidth allocation strategy can be determined as a first bandwidth deviation value change value, which can represent the degree of network influence of bandwidth allocation to the mobile communication device according to the second bandwidth allocation strategy.

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

[0067] S320, when the first bandwidth deviation value change value is less than a preset bandwidth deviation value change value, the 5G core network determines a corrected second location information of the mobile communication device through the plurality of CPE devices, dynamically determines a corrected second bandwidth allocation strategy of the mobile communication device between the plurality of CPE devices through 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 a preset bandwidth deviation value change value, it means that the optimization of bandwidth allocation to the mobile communication device is not good. Since the location information of the CPE device is indoor, the 5G core network can determine a corrected second location information of the mobile communication device through the plurality of CPE devices to further improve the positioning accuracy of the location of the mobile communication device.

[0069] ​After obtaining the corrected second position information, the corrected second bandwidth allocation strategy of the mobile communication device among the plurality of CPE devices can be dynamically determined according to 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 strategy, so as to improve the network allocation effect of the mobile communication device according to the corrected second bandwidth allocation strategy.

[0070] The above-mentioned implementation mode has the beneficial effect that the network allocation state of the mobile communication device is evaluated according to the first bandwidth deviation value change value and the position information of the CPE device, the corrected second position information of the mobile communication device can be determined according to the plurality of CPE devices, and the network allocation of the mobile communication device is optimized according to the corrected second position information, thereby improving the network allocation effect of the mobile communication device.

[0071] In some implementation modes, Figure 4 A flowchart of a fourth 5G smart park CPE network transmission management method provided by an embodiment of the present application is shown in Figure 4 The above-mentioned method further includes S410 to S430, which will be described in detail below.

[0072] S410, determining the difference between the bandwidth deviation values before and after the bandwidth of the mobile communication device is allocated according to the corrected second bandwidth allocation strategy as the second bandwidth deviation value change value.

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

[0074] S420, when the second bandwidth deviation value change value is less than the preset bandwidth deviation value change value, determining the corrected position information of the CPE device according to the position information of the CPE device, the actual bandwidth values corresponding to before and after the bandwidth of the mobile communication device is allocated according to the second bandwidth allocation strategy, and the actual bandwidth values corresponding to before and after the bandwidth of the mobile communication device is allocated according to the corrected second bandwidth allocation strategy.

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

[0076] When the network allocation effect of the mobile communication device is poor due to the low position accuracy of the CPE device itself, 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 the bandwidth is allocated to the mobile communication device according to the second bandwidth allocation strategy, and the actual bandwidth values corresponding to the mobile communication device before and after the bandwidth is allocated to the mobile communication device according to the corrected second bandwidth allocation strategy, so as to correct the corrected position information of the CPE device.

[0077] Exemplarily, when the corrected position information of the CPE device is corrected, the corrected position information of the CPE device can be corrected according to a 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 by training labeled data. The labeled data can include labeled position information of the CPE device, actual bandwidth values corresponding to the mobile communication device before and after the bandwidth is allocated to the mobile communication device according to the bandwidth allocation strategy, and actual bandwidth values corresponding to the mobile communication device before and after the bandwidth is allocated to the mobile communication device according to the corrected bandwidth allocation strategy.

[0078] S430, the 5G core network determines third position information of the mobile communication device through the corrected position information of the CPE device, dynamically determines a third bandwidth allocation strategy of the mobile communication device between the plurality of 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 third position information of the mobile communication device through the corrected position information of the CPE device, dynamically determines a third bandwidth allocation strategy of the mobile communication device between the plurality of 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 of the mobile communication device through the third bandwidth allocation strategy.

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

[0081] The implementation manner has the beneficial effect that when the location accuracy of the CPE device itself is not high, resulting in poor network allocation effect on the mobile communication device, the location of the CPE device itself is corrected, and the bandwidth allocation of the mobile communication device is optimized according to the corrected CPE device location, thereby improving the bandwidth allocation effect on the mobile communication device.

[0082] The implementation manner also has the beneficial effect that when the bandwidth allocation effect on the mobile communication device is optimized, the third location information of the mobile communication device is determined through the corrected location information of the CPE device, and the bandwidth allocation effect on the mobile communication device is optimized through the corrected location information of the CPE device, thereby ensuring the network optimization effect on the mobile communication device.

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

[0084] S421, acquiring a key service proportion value of the mobile communication device and a network idle capacity proportion value of the current 5G core network.

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

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

[0087] After obtaining the key service proportion value of the mobile communication device, when the key service proportion value of the mobile communication device is greater than or equal to a preset key service proportion value, it indicates that the network priority of the mobile communication device is high, at this time, the preset bandwidth deviation value change value can be 1 minus the difference value of the key service proportion value multiplied by a reference 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 high, improve the numerical 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 of the key service of the mobile communication device.

[0088] After obtaining the key service proportion value of the mobile communication device, when the key service proportion value of the mobile communication device is less than the preset key service proportion value, and when the network idle capacity proportion value is greater than or equal to the preset network idle capacity proportion value, it is indicated that the network priority of the mobile communication device is not high, and the idle bandwidth resource of the current 5G core network is relatively large. At this time, the sum of 1 and the network idle capacity proportion value is multiplied by the reference bandwidth deviation change value to serve as the preset bandwidth deviation change value, the numerical value of the preset bandwidth deviation change value is increased, the number of optimization times of the 5G core network in the case that the network priority of the mobile communication device is not high and the idle bandwidth resource of the 5G core network is relatively large is reduced, and the resource consumption of the 5G core network is reduced.

[0089] The beneficial effect of the above implementation manner is that when the network priority of the mobile communication device is high, 1 is subtracted by the difference value of the key service proportion value multiplied by the reference bandwidth deviation change value to serve as the preset bandwidth deviation change value, and the network optimization effect on the mobile communication device of the key service is ensured.

[0090] The beneficial effect of the above implementation manner is also that when the key service proportion value of the mobile communication device is less than the preset key service proportion value, and when the network idle capacity proportion value is greater than or equal to the preset network idle capacity proportion value, the sum of 1 and the network idle capacity proportion value is multiplied by the reference bandwidth deviation change value, the number of optimization times of the 5G core network in the case that the network priority of the mobile communication device is not high and the idle bandwidth resource of the 5G core network is relatively large is reduced, and the resource consumption of the 5G core network is reduced.

[0091] Figure 5 A flowchart of a fifth CPE network transmission management method of a 5G smart park provided by the embodiment of the application is shown in FIG. 5. Figure 5 As shown in FIG. 5, the method further includes S510 to S520, which are specifically described as follows.

[0092] S510, obtaining the time delay sensitivity of the mobile communication device through the 5G core network, the time delay sensitivity representing the time delay sensitivity degree of the network communication of the mobile communication device.

[0093] In determining the preset bandwidth deviation change value, the time delay sensitivity of the mobile communication device can be obtained through the 5G core network, the time delay sensitivity representing the time delay sensitivity degree of the network communication of the mobile communication device, and then the preset bandwidth deviation change value can be further optimized according to the time delay sensitivity of the mobile communication device.

[0094] S520, when the key service proportion value of the mobile communication device is greater than or equal to the preset key service proportion value, and the time delay sensitivity of the mobile communication device is greater than the preset time delay sensitivity, the preset bandwidth deviation value change value of the mobile communication device is adjusted by 1 minus the difference value of the time delay sensitivity multiplied by the preset bandwidth deviation value change value.

[0095] After obtaining the time delay sensitivity of the mobile communication device, when the key service proportion value of the mobile communication device is greater than or equal to the preset key service proportion value, and the time delay sensitivity of the mobile communication device is greater than the preset time delay sensitivity, it indicates that the service priority of the mobile communication device is high and the time delay sensitivity is large. At this time, the preset bandwidth deviation value change value of the mobile communication device can be adjusted by 1 minus the difference value of the time delay sensitivity multiplied by the preset bandwidth deviation value change value, so as to reduce the preset bandwidth deviation value change value, which can improve the bandwidth optimization effect of the mobile communication device.

[0096] The beneficial effect of the above implementation mode is that when the service priority of the mobile communication device is high and the time delay sensitivity is large, the preset bandwidth deviation value change value is reduced by 1 minus the difference value of the time delay sensitivity multiplied by the preset bandwidth deviation value change value, which can improve the bandwidth optimization effect of the mobile communication device with high time delay sensitivity.

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

[0098]

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

[0100] The beneficial effect of the above implementation mode is that the real-time moving speed of the mobile communication device is detected, and the preset bandwidth deviation value change value is adjusted according to the real-time moving speed of the mobile communication device, so that the high-speed mobile communication device can reduce the preset bandwidth deviation value change value to adjust the frequency of the bandwidth allocation fast strategy, avoid the mismatch of the bandwidth of the mobile communication device caused by the high-speed movement of the mobile communication device, and improve the bandwidth allocation effect of the mobile communication device.

[0101] In some implementations, the method described above can further adjust the preset moving time period through S610 to S620, which will be described in detail below.

[0102] S610, obtain a network idle capacity ratio value of a 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 a preset network idle capacity ratio value, the sum of 1 and the network idle capacity ratio value is multiplied by a reference preset moving time period as the preset moving time period. 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, and the sum of 1 and the network idle capacity ratio value can be multiplied by the reference preset moving time period as the preset moving time period, so as to increase the preset moving time period, and then the area of the target area for obtaining the network congestion index corresponding to the plurality of CPE devices can be increased, and then the number of the plurality of CPE devices for monitoring the network congestion index can be increased, so as to improve the network optimization effect of the mobile communication device.

[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, so as to be able to perform broadband allocation for AGV devices and mobile phones with different moving speeds, and ensure the broadband allocation effect of the AGV devices and mobile phones with different moving speeds.

[0107] The beneficial effects of the above-mentioned implementation manner are that when the current network idle capacity is large, the area of the target area for obtaining the network congestion index corresponding to the plurality of CPE devices is increased, the number of the plurality of CPE devices for monitoring the network congestion index is increased, and the network optimization effect of the mobile communication device of different mobile devices is improved.

[0108] In some implementations, the method described above further includes: obtaining a target area in which the mobile communication device moves in the preset moving time period according to the real-time moving speed, obtaining the network congestion index corresponding to the plurality of CPE devices in the target area, and adjusting the preset bandwidth deviation value change value through the following formula:

[0109]

[0110] wherein, Δ p4 represents the adjusted preset bandwidth deviation value change value, Δ p3 represents the preset bandwidth deviation value change value before adjustment, p represents the sum of the network congestion indexes corresponding to the plurality of CPE devices in the target area, p total represents the sum of the network congestion indexes of all CPE devices in the 5G smart park.

[0111] Exemplarily, when the target area in which the mobile communication device moves at the real-time moving speed in the preset moving time period is determined, the area with the mobile communication device as the center and the moving distance of the mobile communication device in the preset moving time period at the real-time moving speed as the radius can be determined as the target area.

[0112] The above-mentioned implementation mode has the beneficial effect that by determining the target area in which the mobile communication device moves at the real-time moving speed in the preset moving time period, obtaining the network congestion indexes corresponding to the plurality of CPE devices in the target area, and combining the sum of the network congestion indexes of all CPE devices in the 5G smart park to evaluate the network congestion degree corresponding to the plurality of CPE devices in the target area, the preset bandwidth deviation value change value is dynamically adjusted, the signaling storm caused by frequent adjustment can be reduced according to the network congestion degree, and the effect of network optimization is improved.
