Description

Method, device, equipment and storage medium for determining data transmission priority

Technical Field

The present application relates to the field of communication technology, and in particular to a method, apparatus, device and storage medium for determining data transmission priority.

Background technique

With the development of the fifth generation mobile communication technology (5G), augmented reality (AR) and virtual reality (VR) services have become the main scenarios for 5G applications. As the bandwidth requirements for AR and VR services increase, AR and VR services have different data streams, which have different service requirements, and there is a correlation between multiple data streams. For example, audio data streams and video data streams have the requirement of synchronous transmission. If the audio data stream and the video data stream cannot be transmitted synchronously, there will be audio and video asynchrony and data transmission delay. Release-18 in the 3rd Generation Partnership Project (3GPP) defines layered multi-QoS, which can split the service into multiple data streams for carrying, and define different QoS requirements for multiple data streams for protection.

In the above method, when transmitting data in one data stream, excessive protection of unimportant data packets will lead to a waste of wireless resources, and when multiple data streams are used to transmit data, the resource utilization of multiple data streams of the same source is low, so that the current data transmission efficiency is low and the resource utilization is low.

Detailed ways

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

In the description of this application, unless otherwise specified, "/" means "or", for example, A/B can mean A or B. "And/or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" and "plurality" refer to two or more. The words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not limit them to be different.

At present, 5G has various requirements for 2B applications, among which AR services, VR services and mixed reality (MR) are typical scenarios for 5G applications. AR services are technologies that enhance the real world, that is, to implant virtual content in real space, map virtual information (objects, pictures, videos, sounds, etc.) in the real environment, and "seamlessly" integrate real world information and virtual world information, so as to realize the real physical environment and virtual information (such as 3D models, videos, texts, etc.) superimposed on the same screen or space in real time. Different from the completely virtual environment simulated or copied in VR services, AR services use virtual information to supplement the current real world and achieve the effect of augmented reality. VR services are created in a virtual scene, using electronic devices to simulate three-dimensional space, simulating a sense of immersion and presence through senses, bringing users into a virtual simulation world, providing simulation of vision, hearing, touch and other senses, so that users can observe the three-dimensional space in an immersive way. MR services can be directly regarded as the combination of AR services and VR services, and the visualization environment generated after merging real scenes and virtual scenes.

The application of AR, VR and MR services increases the bandwidth demand. In addition, their service requirements are different. On the one hand, AR, VR and MR services have different data streams, and these data streams have different service requirements. On the other hand, there are associations between multiple data streams, such as audio and video synchronization requirements. If synchronization cannot be achieved, duplication or delay will occur, causing data transmission quality problems and affecting user experience. As shown in Figure 1, Release-18 in 3GPP defines layered multi-QoS, which can split services into multiple data streams for carrying and define different QoS requirements for multiple data streams for protection. However, the existing 5G QoS mechanism cannot support multi-stream transmission well, and the unequal importance of service data is not fully utilized by the pipeline. In the case of one QoS flow, excessive protection of unimportant data packets will lead to a waste of wireless resources; even if multiple QoS flows are used, the association between multiple QoS flows of the same source (such as the same IP address) is not considered. Considering the association between multiple QoS flows of the same source will help improve the resource utilization of the pipeline.

A scenario that significantly improves resource utilization is when there is a correlation between multiple QoS flows. When one of the QoS flows loses a packet, the other packets between the multiple flows can be directly discarded. Another feature is to ensure that multiple QoS flows meet the latency requirements. In a time zone, the synchronization sequence of multiple flow packets should be maintained as much as possible. Otherwise, the QoS flow asynchrony caused by latency will also affect the user service experience.

The present invention targets this type of XR service, which includes multiple service flows and there is an association between the service flows. By increasing the QoS linkage coefficient (association), the association between multiple QoS flows is improved to help optimize the scheduling of the wireless network.

A method for determining a data transmission priority provided in an embodiment of the present application may be applicable to a system for determining a data transmission priority. FIG. 2 shows a schematic diagram of a structure of the system for determining a data transmission priority. As shown in FIG. 2 , a system 20 for determining a data transmission priority includes: a first electronic device 21 and a second electronic device 22. Data is transmitted between the first electronic device 21 and the second electronic device 22, and various basic technologies are used based on a Quality of Service (QoS) network to provide a data transmission function between the first electronic device 21 and the second electronic device 22.

The system 20 for determining data transmission priority can be used in the Internet of Things. The system 20 for determining data transmission priority can correspond to multiple electronic devices. In the embodiment of the present application, an example is given in which the system 20 for determining data transmission priority includes two electronic devices (i.e., a first electronic device 21 and a second electronic device 22). The specific number of electronic devices is not limited in this application.

The first electronic device 21 and the second electronic device 22 can be used in the Internet of Things, and can be base stations corresponding to operators or terminal devices.

It should be noted that when the first electronic device 21 and the second electronic device 22 are base stations corresponding to the operator, they can be base stations in any mobile communication system, for example, they can be base stations in a 4G mobile communication system or a 5G mobile communication system, and this application does not make any specific limitations on this.

A method for determining a data transmission priority provided by an embodiment of the present application is described below in conjunction with the accompanying drawings. As shown in FIG3 , a method for determining a data transmission priority provided by an embodiment of the present application includes S201-S202:

S201. Acquire target information while transmitting a first data stream through a first data transmission channel and transmitting a second data stream through a second data transmission channel.

Among them, the target information includes at least one of the following: a preset time difference, a target time difference, an associated parameter, and an initial transmission priority corresponding to the second data stream. The preset time difference is used to indicate the maximum data transmission time difference between the first data stream and the second data stream. The target time difference is the data transmission time difference between the first data stream and the second data stream. The associated parameter is used to indicate the degree of association between the first data stream and the second data stream. Different data transmission channels correspond to different service qualities QoS. The initial transmission priority corresponding to the first data stream is higher than the initial transmission priority corresponding to the second data stream.

Optionally, the above-mentioned preset time difference and associated parameters are predetermined parameter information, wherein the preset time difference is the time interval for the latest transmission completion of the second data stream relative to the first data stream, and the preset time difference can be indicated by T; the associated parameter can be understood as the dependency between the first data stream and the second data stream, which is a numerical value in the form of a percentage, and the associated parameter can be indicated by C _association .

Optionally, the initial transmission priority corresponding to the second data stream is the transmission priority corresponding to the second data stream determined when the first data stream and the second data stream were last transmitted before the current moment.

Optionally, when the first data stream is transmitted through the first data transmission channel and the second data stream is transmitted through the second data transmission channel, the transmission priority corresponding to the second data stream needs to be re-determined again through the acquired target information. That is, after each transmission of the first data stream and the second data stream, the transmission priority corresponding to the second data stream can be re-determined again.

It should be noted that, since the initial transmission priority corresponding to the first data stream is higher than the initial transmission priority corresponding to the second data stream, and there is an association relationship between the first data stream and the second data stream, it is necessary to re-determine the transmission priority corresponding to the second data stream (that is, the data stream with a lower initial transmission priority in the first data stream and the second data stream) after transmitting the first data stream and the second data stream. That is, if the initial transmission priority corresponding to the first data stream is lower than the initial transmission priority corresponding to the second data stream, it is necessary to determine the transmission priority corresponding to the first data stream.

S202: Determine a target transmission priority corresponding to the second data stream based on the target information.

Optionally, the target transmission priority corresponding to the second data flow can be understood as the transmission priority corresponding to the second data transmission channel (such as QoS flow) transmitting the second data flow. The transmission priority is represented by a numerical value, and the larger the numerical value, the higher the priority.

Exemplarily, as shown in FIG4 , it is assumed that the predetermined data transmission scenario includes service flow A (i.e., the first data flow) and service flow B (i.e., the second data flow), and there is an association relationship between service flow A and service flow B, that is, the time difference between the completion of transmission of service flow A and service flow B should not be greater than the preset time difference T. In the process of transmitting service flow A and service flow B, it is necessary to record the time when service flow A is completed and the time when service flow B is completed, and determine the time difference t between the time when service flow A is completed and the time when service flow B is completed. Thus, the target transmission priority corresponding to the second data flow is determined again through the pre-acquired target information and the determined time difference t.

In one design, as shown in FIG. 5, a method for determining a data transmission priority provided in an embodiment of the present application may further include S301:

S301: When the association parameter is greater than the preset association parameter, if the target data stream is lost, discard the data streams other than the target data stream in the first data stream and the second data stream.

The target data stream is any one of the first data stream and the second data stream.

Optionally, a reference value corresponding to the associated parameter (i.e., a preset associated parameter) can be pre-set, so that by judging the size relationship between the associated parameter and the preset associated parameter, the processing result of the other data stream between the first data stream and the second data stream can be determined when either data stream is lost.

It can be understood that when the association parameter is greater than the preset association parameter, the correlation between the first data stream and the second data stream is relatively large. When the target data stream (for example, the first data stream) is lost, since the first data stream and the second data stream need to be combined before processing, it may result in that when the second data stream is transmitted, the first data stream is lost, and the second data stream cannot be processed. Therefore, the second data stream is invalid data. Therefore, when it is determined that the first data stream is lost, the second data stream can be directly discarded without completing the transmission of the second data stream.

Optionally, when the association parameter is less than or equal to the preset association parameter, even if the target data stream is lost, it will not affect the processing of data streams other than the target data stream in the first data stream and the second data stream.

That is, when the association parameter is less than or equal to the preset association parameter, the correlation between the first data stream and the second data stream is small. When the target data stream (for example, the first data stream) is lost, since the correlation between the first data stream and the second data stream is small, the second data stream can be processed separately when the transmission of the second data stream is completed.

In an embodiment of the present application, when the association parameter is greater than the preset association parameter, if the target data stream is lost, the data streams other than the target data stream in the first data stream and the second data stream are discarded. Through the above method, when the correlation between the first data stream and the second data stream is large, the first data stream and the second data stream need to be combined before processing. When one of the data streams is lost, even if the other data stream is transmitted, it is impossible to process the other data stream alone. Therefore, the efficiency of data stream transmission can be improved by directly discarding the other data stream, and the utilization rate of resources can be improved.

In one design, as shown in FIG6 , a method for determining a data transmission priority provided in an embodiment of the present application may further include S401-S402:

S401. When the transmission of the first data stream is completed, based on the target data volume corresponding to the second data stream, reserve storage resources corresponding to the target data volume for the second data stream.

Optionally, when the transmission of the first data stream is completed but the transmission of the second data stream is not completed, the target data stream corresponding to the second data stream can be determined after the transmission of the first data stream is completed, and storage resources corresponding to the target data volume can be reserved for the second data stream, thereby ensuring that when the transmission of the second data stream is completed, there are corresponding storage resources to store the second data stream.

Optionally, the number of successful data packet receptions per unit time and the success rate of data stream transmission completion may be counted; when the transmission success rate corresponding to the data stream is low, the associated parameters corresponding to the data stream are adjusted.

Optionally, when the second data stream transmission is completed, it is also necessary to determine the time difference t between the time when the first data stream transmission is completed and the time when the second data stream transmission is completed, and further determine the size relationship between the time difference t and the preset time difference T.

S402: When the target time difference is greater than the preset time difference, the first data stream and the second data stream are discarded to release the resources corresponding to the first data stream and the second data stream.

Optionally, when it is determined that the time difference t between the time when the first data stream transmission is completed and the time when the second data stream transmission is completed is greater than the preset time difference T (i.e., the third scenario in Figure 4), it can be determined that the received first data stream and the second data stream are invalid data, and the first data stream and the second data stream can be discarded to release the storage resources corresponding to the first data stream and the second data stream.

Optionally, when it is determined that the time difference t between the time when the first data stream transmission is completed and the time when the second data stream transmission is completed is less than or equal to the preset time difference T (i.e., the first scenario or the second scenario in Figure 4), it can be determined that the received first data stream and the second data stream are valid data, and the first data stream and the second data stream can be saved and processed.

It can be understood that the preset time difference T is the delay time corresponding to the completion of transmission of the second data stream that can be tolerated after the first data stream completes transmission. When the preset time difference T is exceeded after the first data stream completes transmission, when the second data stream is received, it can be considered that the second data stream is no longer needed at this time, and the first data stream and the second data stream can be directly discarded to release the storage resources corresponding to the first data stream and the second data stream.

In an embodiment of the present application, when the transmission of the first data stream is completed, by reserving storage resources corresponding to the target data amount for the second data stream based on the target data amount corresponding to the second data stream, it is possible to ensure that there are storage resources corresponding to the second data stream when the second data stream is received; and by judging whether the target time difference is greater than the preset time difference, when the target time difference is greater than the preset time difference, it is determined that the second data stream is invalid data, the first data stream and the second data stream are discarded, and the storage resources corresponding to the first data stream and the second data stream are released to improve resource utilization.

In one design, as shown in FIG. 7 , in a method for determining a data transmission priority provided by an embodiment of the present application, the method in step S202 may specifically include S501-S502:

S501: When the target time difference is less than or equal to the preset time difference, determine a target ratio between the target time difference and the preset time difference, and determine the product of the target ratio and the associated parameter as a first parameter.

Optionally, when the target time difference t is less than or equal to the preset time difference T, a target ratio between the target time difference and the preset time difference may be determined: The product of the target ratio and the association parameter C _assosion is determined as the first parameter:

It can be understood that the transmission priority corresponding to the data stream is inversely proportional to the corresponding target time difference t when the transmission of the two data streams is completed: that is, from the receipt of the first data stream, within the preset time difference T, the transmission priority corresponding to the second data stream per unit time increases according to the unit time to ensure that the second data stream is transmitted within an acceptable maximum delay time.

S502: Determine the sum of the first parameter and the preset parameter as the second parameter, and determine the product of the second parameter and the initial transmission priority corresponding to the second data stream as the target transmission priority corresponding to the second data stream.

Optionally, the preset parameter may be 1, so that the sum of the first parameter and the preset parameter is determined as the second parameter: The product of the second parameter and the initial transmission priority _PB corresponding to the second data stream is determined as the target transmission priority _PB ' corresponding to the second data stream.

That is, the target transmission priority _PB ' corresponding to the second data stream can be determined by the following formula 1:

In one design, the second data stream includes N sub-data, which are transmitted sequentially in the second data transmission channel, and the target time difference includes N sub-time differences, one sub-data corresponds to one sub-time difference, and N is a positive integer; as shown in FIG8, in a method for determining a data transmission priority provided by an embodiment of the present application, the method in step S202 above may specifically include S601-S604:

S601: When the largest sub-time difference among N sub-time differences is less than or equal to a preset time difference, determine a first ratio between the i-th sub-time difference and the preset time difference, and determine a second ratio between i and N.

Wherein, i is a positive integer less than or equal to N.

Optionally, when the second data stream is sub-packetized due to resource limitation, the number of sub-packets corresponding to the second data stream also needs to be considered.

Exemplarily, as shown in Figure 9, assuming that the second data stream is split into N (for example, N is 5) sub-data, it is necessary to determine the transmission priority corresponding to each sub-data in the N sub-data separately, and then determine the target transmission priority corresponding to the second data stream according to the transmission priority corresponding to each sub-data.

Specifically, for the i-th sub-data among the N sub-data, it is necessary to first determine a first ratio between the i-th sub-time difference _ti corresponding to the i-th sub-data and the preset time difference T: And determine the second ratio:

S602: Determine the sum of the first ratio and the second ratio as a third parameter, and determine the product of the third parameter and the associated parameter as a fourth parameter.

Further, the sum of the first ratio and the second ratio is determined as the third parameter: The product of the third parameter and the associated parameter is determined as the fourth parameter:

S603: Determine the sum of the fourth parameter and the preset parameter as the fifth parameter, and determine the product of the fifth parameter and the initial transmission priority corresponding to the second data stream as the transmission priority corresponding to the i-th sub-data.

Among them, the i-th sub-data corresponds to the i-th sub-time difference.

Further, the sum of the fourth parameter and the preset parameter is determined as the fifth parameter:

The product of the fifth parameter and the initial transmission priority corresponding to the second data stream is determined as the transmission priority corresponding to the i-th sub-data.

That is, the target transmission priority corresponding to the second data stream when the second data stream is packetized can be determined by the following formula 2:

S604: Determine a target transmission priority corresponding to the second data stream based on the transmission priority corresponding to each sub-data in the N sub-data.

Optionally, the average value of the transmission priority corresponding to each sub-data in the N sub-data may be finally determined as the target transmission priority corresponding to the second data stream.

The embodiment of the present application provides a method for determining data transmission priority, in which, when a first data stream is transmitted through a first data transmission channel and a second data stream is transmitted through a second data transmission channel, target information including at least one of a preset time difference, a target time difference, an associated parameter, and an initial transmission priority corresponding to the second data stream is obtained, and based on the preset time difference indicating the maximum data transmission time difference corresponding to the first data stream and the second data stream, the target time difference corresponding to the first data stream and the second data stream, the associated parameter indicating the degree of association between the first data stream and the second data stream, and the initial transmission priority corresponding to the second data stream, the target transmission priority corresponding to the second data stream is determined. Through the above method, after each transmission of the first data stream and the second data stream having an associated relationship, the target transmission priority corresponding to the second data stream with a lower initial transmission priority in the first data stream and the second data stream can be re-determined based on the obtained target information, so that when the first data stream and the second data stream are transmitted again in the subsequent transmission, the efficiency of data stream transmission can be improved, and the utilization of resources can be improved.

The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method.
