Fig. 1 is a schematic diagram of an application scenario of a bandwidth duration duty cycle determination method according to some embodiments of the present disclosure.
In the application scenario of fig. 1, the target terminal 101 may be connected together with other terminals 102 and 103 on the same target wireless access device 104. The target wireless access device 104 may be connected to the router 105 and access a channel (e.g., channel 1). The target terminal 101 may perform a remote audio/video call with a remote auxiliary terminal 107 through a target wireless access device 104, a router 105, and a public network 106. Prior to introducing the bandwidth duration duty cycle determination method of some embodiments of the present disclosure, the bandwidth duration duty cycle (airtime) allocated to the target terminal 101 and the other terminals 102 and 103 may each be 33%. After introducing the bandwidth duration duty cycle determination method of some embodiments of the present disclosure, the bandwidth duration duty cycles (airtime) allocated to the target terminal 101 and the other terminals 102 and 103 may be 60%, 20%, and 20%, respectively.
It should be understood that the number of target terminals, other terminals, target wireless access devices, and remote assistance terminals in fig. 1 is merely illustrative. There may be any number of target terminals, other terminals, target wireless access devices, and remote assistance terminals, as desired for implementation.
With continued reference to fig. 2, a flow 200 of some embodiments of a bandwidth duration duty cycle determination method according to the present disclosure is shown. The bandwidth duration duty ratio determining method comprises the following steps:
in step 201, in response to receiving the device information sent by the target terminal, registration authentication is performed on the target terminal using the device information.
In some embodiments, the execution body of the bandwidth duration duty ratio determining method may perform registration authentication on the target terminal by using the device information in response to receiving the device information sent by the target terminal. Wherein the device information includes a network bandwidth that can be targeted. The target terminal is a terminal for executing an audio/video service. The target network bandwidth may be a bandwidth required by the target terminal. The audio and video service may be an audio and video service in a remote assistance scenario. The registration may be recording an identification of the target terminal and the device information. The identification of the target terminal may be an IP address (Internet Protocol Address ) or a device unique identification of the target terminal. The authentication may be a generation of a key for establishing between the target terminal and the execution subject according to a communication protocol. The target terminal may be a head-mounted display device. For example VR glasses or AR glasses, etc.
As an example, the target network bandwidth included in the above device information may be 20M/s.
In some optional implementations of some embodiments, before the executing body performs registration authentication on the target terminal by using the device information in response to receiving the device information sent by the target terminal, the executing body may further execute the following steps:
first, the target multicast address is monitored. The target multicast address may be any one of the multicast addresses that communicate with the target wireless access device.
And a second step of creating a monitor address and a monitor port in response to receiving a data message sent to the target multicast address by the target terminal when the target terminal is connected to the target wireless access device, and sending the monitor address and the monitor port to the target terminal. The monitoring address and the monitoring port are used for the target terminal to communicate with the target wireless access device.
Step 202, obtaining the channel utilization of the target channel.
In some embodiments, the executing entity may obtain the channel utilization of the target channel. The target channel is a channel accessed by the wireless access device connected with the target terminal. As an example, the bandwidth of the target channel may be 100M/s. The channel utilization of the target channel may be 70%. It may be shown that the amount of data actually transmitted by the target channel within 1 second is 70% of 100M, i.e., 70M. It can also be shown that the target channel is actually used to transmit data for 70% of 1 second, i.e. 0.7 seconds, in 1 second.
In step 203, in response to determining that the channel utilization satisfies the preset condition, a bandwidth duration to be allocated of the target wireless access device is determined.
In some embodiments, the executing body may determine the bandwidth duration to be allocated of the target wireless access device in response to determining that the channel utilization satisfies a preset condition. The target wireless access device may be a wireless access device connected to the target terminal. The preset condition may be that the channel utilization is equal to or less than a preset threshold. In practice, the preset threshold may be set according to practical applications, which is not limited herein. As an example, the above-mentioned preset threshold value may be 95%.
If the channel utilization rate is less than or equal to the preset threshold value, the target channel can be indicated to have enough space-time resources and bandwidth duration duty ratio for allocation. If the channel utilization is greater than the preset threshold, the target channel is indicated to be busy, and enough space-time resources and bandwidth duration duty ratio are not available for allocation.
Optionally, the preset condition may be that a sum of a difference value between the channel utilization and the first value and a sum of the second value is less than or equal to the preset threshold. The first value may be a channel utilization ratio occupied by a wireless access device connected to the target terminal. The second value may be a channel utilization rate required to be occupied by the target terminal. The second value may be expressed as a ratio of the target network bandwidth to the target channel bandwidth. In some optional implementations of some embodiments, the determining, by the executing body, a bandwidth duration to be allocated of the target wireless access device may include the following steps:
the first step, the occupied bandwidth duration duty ratio of the target wireless access device is determined by using the real-time data transmission quantity of the target wireless access device and the wireless data transmission rate of the target channel. The real-time data transmission amount may be a real-time data transmission amount of the target wireless access device per unit time. The wireless data transmission rate may be represented by a network bandwidth of the target channel. The ratio of the real-time data transmission amount to the wireless data transmission rate may be determined as the occupied bandwidth duration ratio.
As an example, the unit time may be 1 second. The real-time data transmission amount may be 30M. The wireless data transmission rate may be 100M/s. The occupied bandwidth duration may be 30%.
And secondly, adjusting the occupied bandwidth duration duty ratio by utilizing the channel utilization ratio to obtain the bandwidth duration duty ratio to be allocated. Wherein the preemptive bandwidth duration can be determined using the channel utilization described above. And determining the sum of the preemptive bandwidth time and the occupied bandwidth time as the duty ratio of the bandwidth time to be allocated.
As an example, the channel utilization is 70%. It may be indicated that there is still a 30% bandwidth duration duty cycle unoccupied every 1 second. The bandwidth to be allocated may have a duration of 60%.
And 204, determining the bandwidth duration duty ratio of each terminal connected with the target wireless access equipment according to the target network bandwidth and the bandwidth duration duty ratio to be allocated.
In some embodiments, the executing body may determine a bandwidth duration ratio of each terminal connected to the target wireless access device according to the target network bandwidth and the bandwidth duration ratio to be allocated.
First, a ratio of the target network bandwidth to the bandwidth of the target channel may be determined as the target bandwidth duration ratio. And then, the difference value between the to-be-allocated bandwidth duration ratio and the target bandwidth duration ratio can be evenly and flatly allocated to other terminals connected with the target wireless access equipment.
In some optional implementations of some embodiments, the executing body may determine, according to the target network bandwidth and the bandwidth duration to be allocated, a bandwidth duration ratio of each terminal connected to the target wireless access device, where the executing body may include the following steps:
and step one, determining the ratio of the target network bandwidth to the wireless data transmission rate of the target channel as the initial bandwidth duration duty ratio of the target terminal.
And secondly, determining the sum of the initial bandwidth duration duty ratio and the target redundancy value as the bandwidth duration duty ratio of the target terminal. The target redundancy value may be set to be the same as the initial bandwidth duration. Or may be preset to a fixed value.
As an example, the target network bandwidth may be 20M/s. The wireless data transmission rate of the target channel may be 100M/s. The initial bandwidth duration duty cycle may be 0.2. The target redundancy value may also be 0.2. The bandwidth duration of the target terminal may be 0.4.
Therefore, by setting the target redundancy value, a sufficient bandwidth duration duty ratio is allocated to the target terminal. Thereby ensuring that the audio and video service in the target terminal can occupy enough air interface resources.
And thirdly, evenly distributing the difference value between the bandwidth duration duty ratio to be distributed and the bandwidth duration duty ratio of the target terminal to other terminals. Wherein the other terminals are terminals other than the target terminal among the terminals connected to the target wireless access device.
As an example, the bandwidth duration to be allocated duty cycle may be 0.6. The number of the other terminals is two. The allocated bandwidth duration of each other terminal may be 0.1.
Optionally, the executing body determines the bandwidth duration ratio of each terminal connected to the target wireless access device according to the target network bandwidth and the bandwidth duration ratio to be allocated, and further includes the following steps:
the first step, in response to obtaining the actual bandwidth duration duty ratio of each other terminal, determining whether the sum of the actual bandwidth duration duty ratios and the bandwidth duration duty ratio of the target terminal is smaller than the bandwidth duration duty ratio to be allocated. The other terminals may be terminals other than the target terminal among the terminals connected to the target wireless access device.
As an example, the number of the other terminals is two. And the actual bandwidth duration of the other terminals may be 0.1 and 0.05, respectively. And the sum of the actual bandwidth time period duty ratio and the bandwidth time period duty ratio of the target terminal is 0.35, which is smaller than the bandwidth time period duty ratio to be allocated by 0.6.
And a second step of setting the actual bandwidth duration duty ratio of each other terminal as the bandwidth duration duty ratio of each other terminal and updating the bandwidth duration duty ratio of the target terminal in response to determining that the sum of the actual bandwidth duration duty ratios and the bandwidth duration duty ratio of the target terminal are smaller than the bandwidth duration duty ratio to be allocated. And the sum of the updated bandwidth duration duty ratio of the target terminal and the actual bandwidth duration duty ratio is equal to the bandwidth duration duty ratio to be allocated. The bandwidth duration duty ratio of the target terminal may be updated to be a difference value between the bandwidth duration duty ratio to be allocated and the sum of the actual bandwidth duration duty ratios.
The above embodiments of the present disclosure have the following advantageous effects: according to the bandwidth duration duty ratio determining method of some embodiments of the present disclosure, the occupation requirement of the terminal executing the audio/video service on the air interface resource can be considered pointedly, the real-time transmission of the data message of the audio/video service is reduced, the situation that the audio/video is blocked is reduced, and the experience of the user wearing the head-mounted display device is improved. Specifically, the reasons for the reduced real-time transmission of the data message and the occurrence of the clip of the audio and the video service are as follows: the occupation time length of the air interface resources is automatically and indiscriminately distributed for each terminal connected to the wireless access equipment without pertinence considering the occupation requirement of the air interface resources by the terminal executing the audio/video service. Based on this, in the bandwidth duration duty ratio determining method of some embodiments of the present disclosure, when the bandwidth duration duty ratio is allocated, considering the requirement of the terminal executing the audio and video service on the bandwidth, the requirement of the terminal executing the audio and video service on the bandwidth is preferentially ensured to be satisfied, and then the remaining bandwidth duration duty ratio is allocated to other terminals. Therefore, the real-time transmission of the data message of the audio and video service is reduced, the situation that the audio and video is blocked is reduced, and the experience of a user wearing the head-mounted display device is improved.
With further reference to fig. 3, a flow 300 of further embodiments of a bandwidth duration duty cycle determination method is shown. The flow 300 of the bandwidth duration duty ratio determining method includes the following steps:
in step 301, in response to receiving the device information sent by the target terminal, registration authentication is performed on the target terminal using the device information, and the transmission priority of the target terminal is configured as the transmission priority included in the device information.
In some embodiments, the execution body of the bandwidth duration duty ratio determining method may perform registration authentication on the target terminal using the device information in response to receiving the device information sent by the target terminal, and configure a transmission priority of the target terminal as a transmission priority included in the device information. The device information may include a target network bandwidth and a transmission priority, and the target terminal is a head-mounted display device for executing an audio/video service. For example VR glasses or AR glasses, etc.
As an example, the above transmission priority levels are VI, VO, BE, BK four ranks. Wherein, the transmission priority is VI > VO > BE > BK from high to low respectively. Under the condition of equal transmission priority, the transmission opportunities of the data messages are equal. The target network bandwidth may be a bandwidth required by the target terminal. The audio and video service may be an audio and video service in a remote assistance scenario. The registration may be recording an identification of the target terminal and the device information. The identifier of the target terminal may be an IP address or a device unique identifier of the target terminal. The authentication may be a generation of a key for establishing between the target terminal and the execution subject according to a communication protocol.
As an example, the transmission priority included in the above device information may BE.
Step 302, obtaining the channel utilization of the target channel.
In step 303, in response to determining that the channel utilization satisfies the preset condition, a bandwidth duration to be allocated of the target wireless access device is determined.
Step 304, determining the bandwidth duration duty ratio of each terminal connected with the target wireless access device according to the target network bandwidth and the bandwidth duration duty ratio to be allocated.
In some embodiments, the specific implementation manner of steps 302-304 and the technical effects thereof may refer to steps 202-204 in those embodiments corresponding to fig. 2, which are not described herein.
In step 305, in response to determining that the channel utilization does not meet the preset condition, the transmission priority of the target terminal is reconfigured.
In some embodiments, the executing body may reconfigure the transmission priority of the target terminal in response to determining that the channel utilization does not satisfy the preset condition. Wherein the reconfigured transmission priority is higher than the previously configured transmission priority.
As an example, if the transmission priority of the preceding configuration is BE. The reconfigured transmission priority may be VO.
Therefore, when the target channel does not have enough air interface resources and bandwidth occupation time length proportion for allocation, the transmission priority of the prior configuration can be improved, so that the transmission priority of the data message sent to the target terminal is improved, and the priority transmission is ensured.
In step 306, in response to receiving the data packet sent to the target terminal, the transmission priority of the data packet is set to the transmission priority configured for the target terminal.
In some embodiments, the executing body may set a transmission priority of the data packet to a transmission priority configured for the target terminal in response to receiving the data packet sent to the target terminal.
Therefore, after the data message reaches the execution body, the transmission priority of the data message can be set as the transmission priority configured by the target terminal. Furthermore, the situation that the real-time performance of the data packet transmission is reduced due to the reduction of the transmission priority after the data packet sent to the target terminal is transmitted through the public network and the router can be avoided.
As can be seen from fig. 3, compared to the description of some embodiments corresponding to fig. 2, the flow 300 of the bandwidth duration duty cycle determination method in some embodiments corresponding to fig. 3 embodies the improvement of the data transmission priority of the received data packet sent to the target terminal. Therefore, the schemes described in the embodiments can enable the data message to be sent preferentially through the improvement of the data transmission priority, and further improve the communication instantaneity. Further, the experience of the user using the target terminal (e.g., head-mounted display device) may be further enhanced.
