Description

Technical Field

[0001] This application relates to the field of head-mounted display technology, and in particular to a bandwidth allocation method, apparatus, device, and computer-readable storage medium. Background Technology

[0002] With the rapid development of AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality) technologies, head-mounted display devices, such as AR / VR / MR devices, have gradually integrated into people's daily lives and become an important part of modern technological experiences. Among these, the proper allocation of network bandwidth is a key factor affecting user experience in the usage scenarios of head-mounted display devices.

[0003] Currently, the common bandwidth allocation method is to statically allocate a fixed network bandwidth based on the load of each head-mounted display device. For example, the greater the load, the greater the network bandwidth. This bandwidth allocation method can maintain the basic operating speed of head-mounted display devices in single-user or low-concurrency scenarios. However, as the number of head-mounted display device users increases, especially in large-space multi-user concurrent scenarios, the static bandwidth allocation method cannot respond to changes in user density in real time and adjust bandwidth resources accordingly, resulting in unreasonable bandwidth resource allocation and thus reducing bandwidth utilization.

[0004] Therefore, how to improve the bandwidth utilization of computer networks is an urgent problem that needs to be solved. Summary of the Invention

[0005] The main objective of this application is to provide a bandwidth allocation method, apparatus, device, and computer-readable storage medium, which aims to improve the bandwidth utilization of computer networks.

[0006] To achieve the above objectives, this application provides a bandwidth allocation method applied to a bandwidth allocation system, the bandwidth allocation system being communicatively connected to multiple head-mounted display devices, the bandwidth allocation method comprising:

[0007] Monitor the location of a target user using a target head-mounted display device within a preset network coverage area, wherein the target head-mounted display device is one of the multiple head-mounted display devices that is in an on state;

[0018] In an embodiment, downlink transmission of first data generated by the wireless access point is preferentially performed in a first preset frequency band, and uplink transmission of second data generated by the target head-mounted display devices is preferentially performed in a second preset frequency band, wherein a data type of the first data is an audio type or a video type, a data type of the second data is a best-effort type or a background type, and the first preset frequency band is higher than the second preset frequency band.

[0019] In an embodiment, after the step of dynamically allocating bandwidth resources to the target head-mounted display devices in the unit coverage ranges corresponding to the user densities based on the target bandwidth resource amounts, the method further comprises:

[0020] Monitor the data latency of the target head-mounted display device, and when the data latency is greater than a preset duration, pause the transmission of background data until the data latency is less than or equal to the preset duration.

[0021] In one embodiment, after the step of dynamically allocating bandwidth resources to the target head-mounted display device within the unit coverage area corresponding to the user density based on the target bandwidth resource amount, the method further includes:

[0022] The system monitors the data throughput of the target head-mounted display device, and when the data throughput is less than a preset throughput, it dynamically allocates bandwidth resources to the target head-mounted display device based on a preset bandwidth resource amount, until the data throughput is greater than or equal to the preset throughput, wherein the preset bandwidth resource amount is greater than the target bandwidth resource amount.

[0023] Furthermore, to achieve the above objectives, this application also provides a bandwidth allocation device, which is applied to a bandwidth allocation system that is communicatively connected to multiple head-mounted display devices. The bandwidth allocation device includes:

This application monitors the user locations of target users using head-mounted display devices within a preset network coverage area, and determines the user density within each unit coverage area based on the user locations. Each unit coverage area is obtained by segmenting the preset network coverage area, and the user density is the density of users using head-mounted display devices within each unit coverage area. Finally, a preset target bandwidth resource amount is determined for each user density, and bandwidth resources are dynamically allocated to the head-mounted display devices within the unit coverage area corresponding to that user density based on the target bandwidth resource amount.

[0040] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0042] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The main solution of this application is: monitoring the location of target users using target head-mounted display devices within a preset network coverage area, wherein the target head-mounted display device is an active device among a plurality of head-mounted display devices; determining the user density within each unit coverage area based on the user location, wherein each unit coverage area is obtained by dividing the preset network coverage area, and the user density is the density of users using the target head-mounted display device within the unit coverage area; determining a preset target bandwidth resource amount corresponding to each user density, and dynamically allocating bandwidth resources to the target head-mounted display devices within the unit coverage area corresponding to the user density based on the target bandwidth resource amount.

[0044] Currently, the common bandwidth allocation method is to statically allocate a fixed network bandwidth based on the load of each head-mounted display device. For example, the greater the load, the greater the network bandwidth. This bandwidth allocation method can maintain the basic operating speed of head-mounted display devices in single-user or low-concurrency scenarios. However, as the number of head-mounted display device users increases, especially in large-space multi-user concurrent scenarios, the static bandwidth allocation method cannot respond to changes in user density in real time and adjust bandwidth resources accordingly, resulting in unreasonable bandwidth resource allocation and thus reducing bandwidth utilization.

[0045] This application monitors the location of users using head-mounted display devices within a preset network coverage area in real time, and determines the user density in each small area based on the user location. It then dynamically allocates bandwidth resources to the head-mounted display devices in the small area corresponding to the user density based on a preset amount of bandwidth resources. This achieves real-time response to changes in user density within each unit's coverage area, dynamically adjusting the bandwidth resources of each head-mounted display device, thereby improving the bandwidth utilization of the computer network.

[0046] It should be noted that the execution subject of the bandwidth allocation method in various embodiments of this application can be a bandwidth allocation system, or a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or a bandwidth allocation device capable of performing the above functions. This embodiment does not specifically limit this. The following uses a bandwidth allocation system as the execution subject as an example to describe this embodiment and the following embodiments.

[0047] Based on this, this application proposes a bandwidth allocation method according to a first embodiment. The bandwidth allocation method is applied to a bandwidth allocation system, which is communicatively connected to multiple head-mounted display devices. Please refer to... Figure 1 The bandwidth allocation method includes steps S10 to S30:

[0048] Step S10: Monitor the location of the target user using the target head-mounted display device within the preset network coverage area, wherein the target head-mounted display device is one of the multiple head-mounted display devices that is in an on state;

[0049] It is worth emphasizing that the head-mounted display devices in this embodiment include, but are not limited to, Mixed Reality (MR) devices (such as MR glasses or MR helmets), Augmented Reality (AR) devices (such as AR glasses or AR helmets), Virtual Reality (VR) devices (such as VR glasses or VR helmets), Extended Reality (XR) devices, or some combination thereof, and other display devices with virtual reality functions.

[0050] It should be noted that the bandwidth allocation method of this application is applied to a bandwidth allocation system that is communicatively connected to multiple head-mounted display devices. The network coverage area managed by the bandwidth allocation system is pre-defined, meaning the system is responsible for bandwidth allocation to each device within that network coverage area. Head-mounted display devices that are communicatively connected to the bandwidth allocation system and are in an on state within the pre-defined network coverage area are referred to as target head-mounted display devices. Users within the pre-defined network coverage area who are using the target head-mounted display devices are referred to as target users.

[0051] Real-time monitoring of the location of the target user (hereinafter referred to as user location) who is using the target head-mounted display device within the preset network coverage area.

[0052] In one feasible implementation, the location of the head-mounted display device is determined by the head-mounted display device that is in the on state within the preset network coverage area, and it is detected whether it is being worn by a user. If it is detected that it is being worn by a user, the location of the head-mounted display device is sent to the bandwidth allocation system. The bandwidth allocation system receives the location information sent by each head-mounted display device and determines the location information as the location of the target user who is using the head-mounted display device. That is, the location of the head-mounted display device worn by the target user is taken as the location of the target user.

[0053] In another feasible embodiment, step S10 may include:

[0054] Step S101: Receive user magnetic field information and user infrared information sent by a target head-mounted display device within a preset network coverage area, wherein the user magnetic field information is the magnetic field information collected by the magnetometer of the head-mounted display device, and the user infrared information is the infrared information collected by the infrared sensor of the head-mounted display device.

[0055] It should be noted that user location information is collected by head-mounted display devices that are in an active state within the preset network coverage area. Specifically, magnetic field information (hereinafter referred to as user magnetic field information) is collected by the magnetometer of the head-mounted display device, and infrared information (hereinafter referred to as user infrared information) is collected by the infrared sensor of the head-mounted display device. That is, the user magnetic field information and user infrared information collected by the head-mounted display device are collectively referred to as user location information.

[0056] While the head-mounted display device, which is in an on state within a preset network range, collects user location information, it also sends the user location information to the bandwidth allocation system in real time. The bandwidth allocation system receives the user's magnetic field information and infrared information sent by the head-mounted display device to monitor the user's location in real time.

[0057] Step S102: Based on the user magnetic field information and the user infrared information, determine the user location of the target user using the target head-mounted display device.

[0058] After receiving the user's magnetic field information and user infrared information collected by the target head-mounted display device, the user's location is determined based on the user's magnetic field information and user infrared information.

[0059] Specifically, the user's magnetic field information and infrared information are first preprocessed, including denoising and filtering. Then, a data fusion algorithm is used to fuse the preprocessed data, and the user's location is calculated based on the fused information. This method of determining user location by combining magnetic field and infrared information ensures both accuracy and robustness in positioning.

[0060] In this embodiment, the bandwidth allocation system includes a wireless access point, which communicates with multiple head-mounted display devices. The preset network coverage area is the range that the wireless access point can cover through wireless signal transmission.

[0061] It should be noted that the bandwidth allocation system includes wireless access points, i.e., APs (Access Points). This bandwidth allocation system communicates with multiple head-mounted display devices through wireless access points, and the range that the wireless access points can cover through wireless signal transmission is used as the preset network coverage area.

[0062] Step S20: Determine the user density within the coverage area of ​​each unit based on the user location, wherein each unit coverage area is obtained by dividing the preset network coverage area, and the user density is the density of users using the target head-mounted display device within the unit coverage area;

[0063] It should be noted that the preset network coverage area is divided into multiple sub-areas (hereinafter referred to as unit coverage areas for distinction). The area of ​​each unit coverage area may be equal or unequal. This application embodiment does not limit the size of the area of ​​each unit coverage area.

[0064] The user density within the coverage area of ​​each unit is determined based on the calculated user location. Here, user density refers to the density of users using the target head-mounted display device within the coverage area of ​​the unit.

[0065] In a specific implementation, step S20 may include:

[0066] Step S201: Obtain the signal strength information and network address information of the target head-mounted display device;

[0067] It should be noted that this application does not limit the specific forms of the signal strength information and network address information mentioned above. In the embodiments of this application, the signal strength information includes, but is not limited to, RSSI (Received Significant Strength Indicator) value, and the network address information includes, but is not limited to, MAC address information.

[0068] Send a request command to the target head-mounted display device to obtain signal strength information and network address information, and receive the signal strength information and network address information fed back by the target head-mounted display device based on the request command.

[0069] Step S202: Perform data preprocessing on the user location, the signal strength information, and the network address information respectively to obtain target data;

[0070] Data preprocessing, such as data cleaning, noise reduction, and calibration, is performed on the user's location and the signal strength and network address information of the target head-mounted display device to obtain preprocessed data (hereinafter referred to as target data for distinction), thereby ensuring the accuracy and reliability of the data.

[0071] Step S203: Analyze the target data using a preset Kalman filter algorithm to obtain the user density within the coverage area of ​​each unit.

[0072] The target data is analyzed using a pre-defined Kalman filter algorithm to obtain the user density within the coverage area of ​​each unit.

[0073] For example, such as Figure 2 The diagram illustrates the user density calculation process. First, magnetic field and infrared information are obtained from the target head-mounted display device. Then, based on the magnetic field and infrared information, the location of the target user using the target head-mounted display device is determined. Next, the RSSI value and MAC address information of the target head-mounted display device are combined to perform data cleaning, noise reduction, and calibration to obtain the target data. Finally, the target data is input into a Kalman filter fusion algorithm to obtain the user density within the coverage area of ​​each unit.

[0074] Step S30: Determine the preset target bandwidth resource amount corresponding to each user density, and dynamically allocate bandwidth resources to the target head-mounted display device within the unit coverage area corresponding to the user density based on the target bandwidth resource amount.

[0075] It should be noted that a mathematical model is pre-established between user density and bandwidth allocation to enable adaptive bandwidth allocation based on user density. Specifically, a mapping relationship between user density and bandwidth resources is set, and head-mounted display devices in areas with higher user density are allocated more bandwidth resources to ensure that high-demand users can obtain sufficient bandwidth resources.

[0076] A preset bandwidth resource amount (hereinafter referred to as the target bandwidth resource amount for distinction) is determined for the user density within each unit coverage area. Then, bandwidth resources are dynamically allocated to the target head-mounted display devices within the unit coverage area corresponding to that user density based on the target bandwidth resource amount. That is, it should be understood that the amount of bandwidth resources allocated to the target head-mounted display devices based on the target bandwidth resource amount is the same as the target bandwidth resource amount, and the bandwidth resources allocated to the target head-mounted display devices within each unit coverage area are equal.

[0077] This application embodiment monitors the location of users using head-mounted display devices within a preset network coverage area in real time, and determines the user density in each small area based on the user location. It then dynamically allocates bandwidth resources to the head-mounted display devices in the small area corresponding to the user density based on a preset amount of bandwidth resources. This achieves real-time response to changes in user density within each unit's coverage area, dynamically adjusting the bandwidth resources of each head-mounted display device, thereby improving the bandwidth utilization of the computer network.

[0078] Based on the first embodiment of this application, in the second embodiment of this application, the same or similar content as in the first embodiment can be referred to the above description and will not be repeated hereafter. On this basis, downlink transmission of the first data generated by the wireless access point is preferentially executed in a first preset frequency band, and uplink transmission of the second data generated by the target head-mounted display device is preferentially executed in a second preset frequency band. The data type of the first data is audio or video, and the data type of the second data is best-effort or background. The first preset frequency band is higher than the second preset frequency band.

[0079] It should be noted that, to address the issue that traditional WiFi frequency band allocation strategies fail to fully utilize the multi-band characteristics of WiFi 7, thus limiting network performance improvements, this application adjusts the priority of WiFi EDCA (Enhanced Distributed Channel Access) parameters based on the characteristics of frequency band transmission data. This includes priority types such as VI (Video), VO (Voice), BE (Best Effort), and BK (Background). Each priority type includes four parameters: CWmin (Content Window Minimum), CWmax (Content Window Maximum), AIFS (Arbitration Inter-Frame Spacing), and TXOP (Transmission Opportunity). In the 2.4GHz band, BE / BK is increased while VI / VO is decreased, optimizing the rapid transmission of sensor data, time synchronization, and other messages. The 5GHz band only requires audio and video streaming, therefore increasing VIVO and decreasing BE / BK ensures the transmission priority of audio and video streams. That is, it should be understood that best-effort data and background stream data transmission is prioritized in the 2.4GHz band, while audio and video streaming data transmission is prioritized in the 5GHz band. Furthermore, it is worth emphasizing that this application does not limit the specific size of the first and second preset frequency bands. In this application embodiment, the first preset frequency band is higher than the second preset frequency band; the first preset frequency band is the 5GHz band, and the second preset frequency band is the 2.4GHz band.

[0080] The audio and video data generated by the wireless access point (hereinafter referred to as the first data for distinction) is preferentially allocated to the first preset frequency band for downlink transmission, and the best-effort data and background stream data generated by the target head-mounted display device (hereinafter referred to as the second data for distinction) are preferentially allocated to the second preset frequency band for uplink transmission.

[0081] For example, such as Figure 3 The diagram illustrates the frequency band allocation mechanism. In the 5GHz band, audio and video stream data generated by the AP (Access Point) is prioritized for transmission to the STA (Site). It should be noted that STA refers to the wireless client device, i.e., the head-mounted display device. In the 2.4GHz band, best-effort data and background stream data generated by the STA are prioritized for transmission, such as user location information, user actions, data feedback, management frames, and control frames collected by the head-mounted display device.

[0082] In one feasible embodiment, the bandwidth allocation system of this application includes a bandwidth intelligent allocation module for executing the bandwidth allocation process, such as... Figure 4 The diagram illustrates the bandwidth allocation process. First, based on the mapping relationship between user density and bandwidth resources within the coverage area of ​​each unit, a pre-established bandwidth allocation model dynamically allocates bandwidth resources to the target head-mounted display device. Then, based on the application type used by the target user, such as audio-visual applications, interactive VR applications, or other VR applications, the 5GHz band is selected to transmit the audio-visual data required by the audio-visual applications, and the 2.4GHz band is selected to transmit the BE or BK data generated by interactive VR applications and other VR applications.

[0083] Thus, this embodiment maximizes the utilization efficiency of frequency band resources through reasonable frequency band allocation and traffic control. It adjusts the priority of WiFi EDCA parameters according to the characteristics of frequency band transmission data, and utilizes the high bandwidth and dual-band concurrency capabilities of WiFi 7. Only downlink transmission of audio and video streams is performed in the 5GHz band, ensuring a smooth multimedia experience. Management frames, control frames, channel monitoring messages, and user operation feedback messages are transmitted in the 2.4GHz band, reducing the burden on the 5GHz band. In other words, this embodiment, through dual-band collaborative optimization, allocates different types of applications to different frequency bands for transmission. This not only avoids interference between different applications but also maximizes the utilization efficiency of frequency band resources, ensuring high-quality audio and video stream transmission and improving the overall system performance. It significantly improves network performance and user experience in multi-user concurrent scenarios, providing strong support for the widespread application of head-mounted display devices.

[0084] Based on the first and / or second embodiments of this application, in the third embodiment of this application, the content that is the same as or similar to the first and / or second embodiments described above can be referred to the above description and will not be repeated hereafter. Furthermore, after step S30, the bandwidth allocation method of this application further includes:

[0085] Step A10: Monitor the data latency of the target head-mounted display device, and when the data latency is greater than a preset duration, pause the transmission of background data until the data latency is less than or equal to the preset duration.

[0086] It should be noted that the embodiments of this application do not limit the specific length of the preset duration. In this embodiment, the preset duration is set to 50ms. It should be understood that if the data latency of the head-mounted display device exceeds 50ms, it is considered that the current network is congested or there is a performance bottleneck.

[0087] The system monitors the data latency of the target head-mounted display device. If the detected data latency exceeds a preset duration, background data transmission is paused to reduce network congestion until the data latency returns to normal. In other words, if the data latency is less than or equal to the preset duration, it is considered normal, and background data transmission resumes. Essentially, the system monitors the data latency of the target head-mounted display device in real time, and triggers the pause of background data transmission once a data latency exceeding the preset duration is detected.

[0088] In this embodiment, after step S30, the bandwidth allocation method of this application further includes:

[0089] Step B10: Monitor the data throughput of the target head-mounted display device, and when the data throughput is less than a preset throughput, dynamically allocate bandwidth resources to the target head-mounted display device based on a preset bandwidth resource amount until the data throughput is greater than or equal to the preset throughput, wherein the preset bandwidth resource amount is greater than the target bandwidth resource amount.

[0090] It should be noted that this application embodiment does not limit the specific size of the preset throughput. In this application embodiment, the preset throughput is set to 25Mbps. That is, it should be understood that when the throughput of the target head-mounted display device is detected to be less than the preset throughput, it is considered that the data transmission capacity of the current network is limited and bandwidth resources need to be increased. Furthermore, in this application embodiment, the preset bandwidth resource amount is set to be greater than the current target bandwidth resource amount of the target head-mounted display device, but this application embodiment does not limit the specific size of the preset bandwidth resource amount; it can be any value greater than the target bandwidth resource amount. It should be understood that before new bandwidth resources are reallocated to the target head-mounted display device, the bandwidth resources allocated to the target head-mounted display device are the target bandwidth resource amount, and the process of reallocating resources can be regarded as a process of increasing bandwidth resources.

[0091] The system monitors the data throughput of the target head-mounted display device. When the data throughput is detected to be less than a preset throughput, bandwidth resources are dynamically allocated to the target head-mounted display device based on a preset bandwidth resource amount to remove the data transmission capacity limitation until the data throughput returns to a normal level. In other words, when the data throughput is greater than or equal to the preset throughput, it is considered normal, and the bandwidth resource amount allocated to the target head-mounted display device is restored to the target bandwidth resource amount. Essentially, the system monitors the data throughput of the target head-mounted display device in real time, and once the data throughput is detected to be less than the preset throughput, the step of increasing bandwidth resources for the target head-mounted display device is triggered.

[0092] For example, the bandwidth allocation system of this application also includes a performance indicator monitoring module for performing a performance monitoring process, such as... Figure 5The diagram shows the performance monitoring process. Based on the preset latency and throughput, the system continuously monitors user performance metrics, namely data latency and data throughput metrics. It then determines whether the monitored performance metrics are abnormal. If the data latency of the head-mounted display device is detected to be greater than the preset latency of 50ms, the BK transmission is paused. If the data throughput of the head-mounted display device is detected to be less than the preset throughput of 25Mbps, the bandwidth resources allocated to the head-mounted display device are increased.

[0093] Thus, by monitoring user latency and throughput metrics in real time, the system can take timely measures when an anomaly is detected, such as suspending BK transmission or increasing user priority (i.e., increasing the amount of bandwidth resources allocated to the head-mounted display device), to ensure the user's experience quality. When normal operation is detected again, the system can restore normal transmission status, ensuring system stability and reliability.

[0094] This application also provides a bandwidth allocation device, please refer to... Figure 6 The bandwidth allocation device is applied to a bandwidth allocation system, which is communicatively connected to multiple head-mounted display devices. The bandwidth allocation device includes:

[0095] Detection module 10 is used to monitor the location of a target user using a target head-mounted display device within a preset network coverage area, wherein the target head-mounted display device is one of the multiple head-mounted display devices that is in an on state;

[0096] The determining module 20 is used to determine the user density within the coverage area of ​​each unit based on the user location, wherein each unit coverage area is obtained by dividing the preset network coverage area, and the user density is the density of users using the target head-mounted display device within the unit coverage area;

[0097] The dynamic allocation module 30 is used to determine the preset target bandwidth resource amount corresponding to each user density, and dynamically allocate bandwidth resources to the target head-mounted display device within the unit coverage area corresponding to the user density based on the target bandwidth resource amount.

[0098] Optionally, the detection module 10 is further configured to:

[0099] Receive user magnetic field information and user infrared information sent by a target head-mounted display device within a preset network coverage area, wherein the user magnetic field information is magnetic field information collected by the magnetometer of the target head-mounted display device, and the user infrared information is infrared information collected by the infrared sensor of the target head-mounted display device;

[0100] Based on the user's magnetic field information and the user's infrared information, the user's location using the target head-mounted display device is determined.

[0101] Optionally, the determining module 20 is further configured to:

[0102] Obtain the signal strength information and network address information of the target head-mounted display device;
