The technical solution of the present application will be described below by way of examples.
As shown in fig. 2, in a first embodiment of the present application, the qos resource application method of the present application includes the following steps:
step S110, determining the minimum downlink guaranteed bit rate and the maximum downlink bit rate according to the current video path number.
In this embodiment, qoS (Quality of Service ) refers to a technology that a network can provide better service capability for specified network communication by using various basic technologies, and is a security mechanism of the network, which is used to solve the problems of network delay and congestion. The guarantee of QoS is important for networks with limited capacity, in particular for streaming multimedia applications, such as VoIP and IPTV, since these applications require a fixed transmission rate and are also relatively delay sensitive. In order to better obtain the experience of on-site instant viewing for users at large-scale events/performance activities, the application provides an on-site instant multi-screen simultaneous viewing scheme based on dynamic service quality guarantee, and the optimal experience of on-site multi-screen simultaneous viewing users is guaranteed through dynamic service quality adjustment based on different viewing operations of the users.
In this embodiment, for the network QoS guarantee scheme, the network side will preempt the network resources of the NGBR service to guarantee the minimum rate requirement of the GBR service, and consume relatively large network performance, so that the method is generally mainly used for small bandwidth service with relatively high time delay requirement or high-value local service with relatively high requirement for service experience guarantee. The application dynamically adjusts the minimum bandwidth and the maximum bandwidth parameters in the guaranteed bit rate based on the actual demands of users on low delay and bandwidth of the network in a high-value scene, and realizes the best combination of network performance maximization and service demand precision guarantee.
In this embodiment, referring to fig. 8, the video signal after the on-site high-value machine shooting is promoted to the edge cloud node by the low-delay code. And after the low-delay service modules deployed by the edge cloud nodes are received, distributing the low-delay service modules by a low-delay technology. The on-site user accesses the low-delay service module of the edge cloud node through service side equipment, for example, through video playing application, so as to perform multi-screen simultaneous viewing of different high-value visual angles.
The video path number can be selected according to actual conditions. And installing a video playing application on the service side equipment, and simultaneously displaying a plurality of display windows on a display interface of the video playing application so as to enable a user to realize multi-view and multi-position viewing. Each display window plays a video stream. The user can select the V-way machine to watch simultaneously based on the interest points of the user. The number of digits V that the user selects to view may be from 1 up to N digits.
GBRD (Guaranteed Bit rate Down, minimum guaranteed bit rate), represents the bit rate that a GBR bearer can provide. MBRD (Maximun Bit rate Down, maximum guaranteed downlink bandwidth), represents the bit rate that GBR bearers can provide, e.g., the rate policing function can discard excess traffic. When a user prepares to play a video to be played through a video playing application installed on service side equipment, determining the minimum downlink guaranteed bit rate and the maximum downlink guaranteed bandwidth according to the video path number of the video to be played.
In one embodiment, determining the minimum guaranteed downlink bit rate and the maximum guaranteed downlink bit rate according to the current video path number specifically includes the following steps:
step S111, obtaining the code rate of each path of video and a preset coefficient;
step S112, determining the bandwidth according to the product of the weighted value of the code rate of each path of video and the preset coefficient;
step S113, determining the minimum downlink guaranteed bit rate and the maximum downlink bit rate according to the bandwidth.
In this embodiment, in the process of pushing a video signal photographed by a field high-value machine to an edge cloud node by low-delay coding, based on an adaptive coding technology, it is assumed that a code rate CR (unit Mbps) of each path of video stream is set as follows: x= < CR < = y. The code rate is determined by a low latency codec process. The code rate and the preset coefficient of each path of video are obtained, the preset coefficient is the correlation coefficient of the code rate and the air interface bandwidth requirement, and the preset coefficient is recommended to be 1.5 in consideration of the consumption of packet heads, retransmission and the like. The preset coefficient can be adjusted according to actual conditions. For example, assuming that the number V of video paths watched by the user is [1, n ], the downstream air interface bandwidth requirement BW (bandwidth, mbps) watched by the on-site user is:
according to the code rate of each machine bit, the air interface bandwidth requirement can be calculated. After obtaining the bandwidth, determining a minimum downlink guaranteed bit rate and a maximum downlink bit rate according to the bandwidth. In the field low-delay viewing, in order to guarantee the viewing experience of users in a high-density scene, qoS guarantee is dynamically applied to service equipment according to the number of video paths watched by the users.
According to the technical scheme, the lowest air interface bandwidth requirement and the maximum air interface bandwidth requirement of the downlink are determined according to the range of the self-adaptive code rate and the video road number watched by the user on the same screen in the low-delay viewing, so that the network performance capacity and the user service requirement are balanced.
In an embodiment, the bandwidth is greater than or equal to a first bandwidth and less than or equal to a second bandwidth, the minimum guaranteed downlink bit rate is equal to the first bandwidth, and the maximum guaranteed downlink bit rate is equal to the second bandwidth.
In this embodiment, the bandwidth is greater than or equal to the first bandwidth and less than or equal to the second bandwidth, as shown in the following formula:
the GBRD needs to meet the minimum requirement of the air interface bandwidth requirement BW, and the MBRD needs to meet the maximum requirement of the air interface bandwidth requirement BW. I.e. Representing an upward rounding.
Step S120, based on the minimum downlink guaranteed bit rate and the maximum downlink bit rate, sending a service quality resource application to a service device, so that the service device can feed back a service quality resource application response to the service side device based on the service quality resource application.
In this embodiment, in the low-delay viewing, the minimum air interface bandwidth requirement and the maximum air interface bandwidth requirement of the downlink are calculated according to the range of the self-adaptive code rate and the number of machine positions watched by the same screen of the user, and GBR QoS guarantee resources are applied to the network capability open platform. In order to obtain better guarantee, GBR bearing is adopted to guarantee bandwidth, and the minimum downlink guaranteed bit rate and the maximum downlink bit rate are applied according to actual watching of a user.
Specifically, when the user performs the on-site low-delay viewing, the service side device (APP side or service side) initiates a service quality resource application to the service device according to the number of video paths watched by the user. The qos resource application includes a minimum guaranteed bitrate and a maximum bitrate. The service equipment provides a core network connection interface, namely, when the service equipment receives a service quality application request, the service quality application request is forwarded to a core network, and corresponding service quality resources are acquired based on the service quality resource application request through the core network. And simultaneously feeding back the service quality resource application response to the service side equipment. The qos resource application response includes a flag of whether the qos application was successful.
In an embodiment, the sending the qos resource application to the service device based on the minimum guaranteed downlink bit rate and the maximum guaranteed downlink bit rate specifically includes the following steps:
step S121, generating a corresponding service quality resource application according to the minimum downlink guaranteed bit rate, the maximum downlink bit rate and the guarantee type;
step S122, the service quality resource application is sent to the service equipment.
In this embodiment, when a user starts a field low-delay viewing, a service side device (APP side or service side) initiates a service quality resource application to a service device according to a viewing angle/number of machine bits of the user, and the guarantee type is 5 qi=4. Where the definition of 5QI is defined in 3GPP specification 23.501, 5QI is a scalar for pointing to a 5G QoS feature. The application generates the corresponding service quality resource application according to the minimum downlink guaranteed bit rate, the maximum downlink bit rate and the guarantee type, and sends the service quality resource application to the service equipment through the communication protocol, thereby realizing QoS guarantee application.
According to the technical scheme, the minimum downlink guaranteed bit rate and the maximum downlink bit rate can be determined according to the current video path number; based on the minimum downlink guaranteed bit rate and the maximum downlink bit rate, the service equipment can feed back a service quality resource application response to the service side equipment based on the service quality resource application, and the viewing experience of a user is guaranteed in a high-density scene when the user is in a low-delay viewing state, qoS guarantee is dynamically applied to a network side according to the number of machine bit streams watched by the user, the problem of simultaneous blocking of multiple screens is solved, and network performance capacity and user service requirements are balanced.

step S230, the qos resource modification request is sent to the service device, so that the service device can feedback a qos resource modification response to the service side device based on the qos resource modification request.
In this embodiment, when the view angle/number of machine bits/video path number V watched by the user increases or decreases, the service side device initiates a service quality resource modification request to the service device, and sends new GBRD and MBRD to the service device according to the new view angle/number of machine bits/video path number, so that the service device can feed back a service quality resource modification response to the service side device based on the service quality resource modification request, and implement modification of the service quality resource.
In this process, the process of generating the corresponding qos resource modification request according to the minimum downlink guaranteed bit rate, the maximum downlink bit rate, and the type of guarantee is similar to the process of sending the qos resource application to the service device based on the minimum downlink guaranteed bit rate and the maximum downlink bit rate in the first embodiment, and specific reference may be made to the first embodiment, which is not described herein again.
According to the technical scheme, when the user increases or decreases the number of watching units/viewing angles/video paths, the minimum air interface bandwidth requirement and the maximum air interface bandwidth requirement of the downlink are adjusted in real time, and GBR service quality resource modification requests are applied to the service equipment.
