Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
In the description of this application, "/" denotes "or" means, for example, a/B may denote a or B, unless otherwise indicated. "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. Further, "at least one" or "a plurality" means two or more. The terms "first," "second," and the like do not denote any order or importance, but rather the terms "first," "second," and the like do not denote any order or importance.
Currently, the requirements of 5G 2B-oriented applications are various, wherein AR service, VR service and Mixed Reality (MR) are one of the typical scenarios of 5G applications. The AR service is a technology for enhancing the real world, that is, a new technology of implanting virtual content in the real space, mapping virtual information (objects, pictures, videos, sounds, etc.) in the real environment, and integrating the real world information and the virtual world information "seamlessly" to realize that the real physical environment and the virtual information (such as 3D models, videos, characters) are superimposed on the same picture or space in real time. Different from a completely virtual environment simulated or copied in the VR service, the AR service supplements the current real world by using virtual information to realize the effect of augmented reality. The virtual reality simulation system is created in a virtual scene during VR service, utilizes electronic equipment to simulate a three-dimensional space, simulates immersion and presence through sense organs, brings a user to a virtual simulation world, provides simulation about sense organs such as vision, hearing and touch, and enables an experiencer to observe the three-dimensional space personally. The MR service can be directly regarded as a visual environment generated after combining a real scene and a virtual scene, which is obtained by combining an AR service and a VR service.
The application of the AR service, the VR service and the MR service increases the bandwidth requirement, and in addition, the service requirements of the AR service, the VR service and the MR service have different data flows which have different service requirements; on the other hand, there is an association between multiple data streams, e.g. audio and video have synchronization requirements. If synchronization cannot be achieved, duplication or delay occurs, causing problems with the quality of data transmission and also affecting the user experience. As shown in fig. 1, release-18 in 3GPP defines layered multi-QoS, and can split a service into multiple data flows for carrying, and define different QoS requirements for the multiple data flows for guarantee. 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 packets may lead to a waste of radio resources; even if multiple QoS flows are used, the association between the multiple QoS flows of the same source (e.g., the same IP address) is not considered, and considering the association between the multiple QoS flows of the same source in the past will help to improve the resource utilization of the pipe.
A scene for remarkably improving resource utilization rate is that when an association relationship exists among multiple QoS flows, and when one QoS flow loses a packet, other data packets among multiple flows can be directly discarded; another feature is that multiple QoS flows should be guaranteed to meet latency requirements. In a time region, the synchronous timing sequence of multi-stream data packets should be maintained as much as possible, otherwise, qoS streams caused by time delay are not synchronous, which also affects user service experience.
Aiming at the XR service types, the invention comprises a plurality of service flows, and the service flows have an incidence relation, and the incidence relation of the QoS flows is improved by increasing the QoS linkage coefficient (incidence relation), thereby helping the wireless network to optimize and dispatch.
The method for determining the data transmission priority can be applied to a system for determining the data transmission priority. Fig. 2 is a schematic diagram of an architecture of the system for determining the priority of data transmission. As shown in fig. 2, a system 20 for determining a priority for data transmission includes: a first electronic device 21 and a second electronic device 22. Among them, data transmission is performed between the first electronic device 21 and the second electronic device 22, and various basic technologies are used between the first electronic device 21 and the second electronic device 22 based on a Quality of Service (QoS) network to provide a data transmission function.
The system 20 for determining data transmission priority may be used in the internet of things, and the system 20 for determining data transmission priority may correspond to a plurality of electronic devices, in this embodiment, the system 20 for determining data transmission priority includes 2 electronic devices (i.e., the first electronic device 21 and the second electronic device 22) for an exemplary illustration, and the present application is not limited to a specific number of electronic devices.
The first electronic device 21 and the second electronic device 22 may be used for the internet of things, may be base stations corresponding to operators, and may also be terminal devices.
When the first electronic device 21 and the second electronic device 22 are base stations corresponding to an operator, the base stations may be base stations in any mobile communication system, for example, base stations in a 4G mobile communication system and a 5G mobile communication system, which is not limited in this application.
A method for determining a data transmission priority according to an embodiment of the present application is described below with reference to the accompanying drawings. As shown in fig. 3, a method for determining a priority of data transmission provided in an embodiment of the present application includes S201-S202:
s201, under the condition that 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, target information is obtained.
Wherein the target information comprises at least one of: the method comprises the steps of presetting time difference, target time difference, association parameters and initial transmission priority corresponding to a second data stream, wherein the preset time difference is used for indicating the corresponding maximum data transmission time difference between a first data stream and the second data stream, the target time difference is the corresponding data transmission time difference between the first data stream and the second data stream, the association parameters are used for indicating the association degree between the first data stream and the second data stream, different data transmission channels correspond to different QoS (quality of service), and 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 preset time difference and the associated parameter are predetermined parameter information, where the preset time difference is a time interval at which the latest transmission of the second data stream with respect to the first data stream is completed, and the preset time difference may be indicated by T; the association parameter may be understood as a dependency between the first data stream and the second data stream, as a numerical value in percentage form, which may pass through C assosion Indicating the associated parameters.
Optionally, the initial transmission priority corresponding to the second data stream is a transmission priority corresponding to the second data stream determined when the first data stream and the second data stream are transmitted last before the current time.
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 obtained 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 may 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, after the first data stream and the second data stream are transmitted, the transmission priority corresponding to the second data stream (i.e., the data stream with the lower initial transmission priority in the first data stream and the second data stream) needs to be re-determined. 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, the transmission priority corresponding to the first data stream needs to be determined.
S202, determining 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 may be understood as a transmission priority corresponding to a second data transmission channel (for example, qoS flow) for transmitting the second data flow, where the transmission priority is represented by a value, and the higher the value is, the higher the priority is.
For example, as shown in fig. 4, it is assumed that a predetermined data transmission scenario includes a service flow a (i.e., a first data flow) and a service flow B (i.e., a second data flow), and there is an association relationship between the service flow a and the service flow B, that is, a time difference between the completion of transmission of the service flow a and the completion of transmission of the service flow B should not be greater than a preset time difference T. In the process of transmitting the service flow a and the service flow B, it is necessary to record the time when the transmission of the service flow a is completed and the time when the transmission of the service flow B is completed, and determine a time difference t between the time when the transmission of the service flow a is completed and the time when the transmission of the service flow B is completed. Therefore, the target transmission priority corresponding to the second data stream is determined again through the target information acquired in advance and the determined time difference t.
In a design, as shown in fig. 5, in a method for determining a priority of data transmission provided in an embodiment of the present application, the method may further include, in particular, S301:
s301, under the condition that the association parameter is larger than the preset association parameter, if the target data stream is lost, discarding the data streams except 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 association parameter (that is, a preset association parameter) may be preset, so that a processing result of another data stream of the first data stream and the second data stream is determined when any data stream of the first data stream and the second data stream is lost by judging a size relationship between the association parameter and the preset association parameter.
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, and when a 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 and then processed, it may be possible that when the transmission of the second data stream is completed, the second data stream cannot be processed because the first data stream is lost, and therefore the second data stream is invalid data, so that 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, processing of the data streams other than the target data stream in the first data stream and the second data stream may not be affected.
That is, in the case that 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, and in the case that 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, when the transmission of the second data stream is completed, the second data stream can be processed separately.
In this embodiment of the application, when the association parameter is greater than the preset association parameter, if the target data stream is lost, the data streams except for the target data stream in the first data stream and the second data stream are discarded. By the 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 and then processed, and when one data stream is lost, even if the transmission of the other data stream is completed, the other data stream cannot be processed independently, so that the transmission efficiency of the data streams can be improved and the utilization rate of resources can be improved by directly discarding the other data stream.
In a design, as shown in fig. 6, in a method for determining a priority of data transmission provided in an embodiment of the present application, the method may further include S401 to S402:
s401, under the condition that the transmission of the first data stream is completed, reserving storage resources corresponding to the target data volume for the second data stream based on the target data volume corresponding to 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, after the transmission of the first data stream is completed, the target data stream corresponding to the second data stream may be determined, and a storage resource corresponding to the target data volume may be reserved for the second data stream, so that it may be ensured that when the transmission of the second data stream is completed, the corresponding storage resource may store the second data stream.
Optionally, the number of successful receiving times of the data packet in unit time and the success rate of completing data stream transmission may be counted; and when the transmission success rate corresponding to the data stream is lower, adjusting the associated parameters corresponding to the data stream.
Optionally, when the transmission of the second data stream is completed, it is further required to determine a time difference T between the time when the transmission of the first data stream is completed and the time when the transmission of the second data stream is completed, and further determine a size relationship between the time difference T and the preset time difference T.
S402, under the condition that the target time difference is larger than the preset time difference, the first data stream and the second data stream are discarded, and resources corresponding to the first data stream and the second data stream are released.
Optionally, when it is determined that a time difference T between the time when the transmission of the first data stream is completed and the time when the transmission of the second data stream is completed is greater than the preset time difference T (i.e., the third scenario in fig. 4), it may be determined that the received first data stream and the received second data stream are invalid data, and the first data stream and the second data stream may be discarded, so as 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 transmission of the first data stream is completed and the time when the transmission of the second data stream is completed is smaller than or equal to the preset time difference T (i.e., the first scenario or the second scenario in fig. 4), it may be determined that the received first data stream and the received second data stream are valid data, and the first data stream and the second data stream may be stored and processed.
It can be understood that the preset time difference T is a delay time that can be tolerated when the transmission of the second data stream is completed after the transmission of the first data stream is completed, and when the preset time difference T is exceeded after the transmission of the first data stream is completed, and the second data stream is received, it may be considered that the second data stream is not needed at this time, the first data stream and the second data stream may be directly discarded, and the storage resources corresponding to the first data stream and the second data stream are released.
In the embodiment of the present application, when the transmission of the first data stream is completed, a storage resource corresponding to a target data volume is reserved for the second data stream based on the target data volume corresponding to the second data stream, so that when the second data stream is received, the storage resource corresponding to the second data stream is ensured; and determining the second data stream as invalid data by judging whether the target time difference is greater than the preset time difference or not, discarding the first data stream and the second data stream, and releasing storage resources corresponding to the first data stream and the second data stream so as to improve the utilization rate of the resources.
In a design, as shown in fig. 7, in a method for determining a priority of data transmission provided in an embodiment of the present application, the method in step S202 may specifically include S501-S502:
s501, under the condition that the target time difference is smaller than or equal to the preset time difference, determining a target ratio between the target time difference and the preset time difference, and determining a product between 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:
and correlating the target ratio with a correlation parameter C assosion The product between is determined as the first parameter:
it can be understood that the transmission priority corresponding to a data stream is inversely proportional to the corresponding target time difference t when the transmission of two data streams is completed: that is, within a preset time difference T from the reception of the first data stream, the transmission priority corresponding to the second data stream in each unit time climbs according to the unit time, so as to ensure that the second data stream completes transmission within the acceptable maximum delay time.
S502, determining the sum of the first parameter and the preset parameter as a second parameter, and determining 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.
