Description

Resource allocation method and related device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource allocation method and a related apparatus.

Background

At present, in order to enable network communication to provide better service capability for services, differentiated services can be provided for different services to improve user experience. For example, an end-to-end Quality of Service (QoS) mechanism is adopted to establish an end-to-end Service between a terminal and an opposite end entity, wherein a core network and a bearer network ensure various parameter indexes in the QoS mechanism by using various configuration information. For example, the core network may converge Internet Protocol (IP) streams that belong to the same session, port, and service with the same Qos transmission requirement, and determine configuration information of a unified Qos stream according to service feature information of the IP streams; furthermore, the core network can inform the configuration information of the QOS flow to the access network, so that the access network carries out scheduling transmission of data according to the configuration information of the QOS flow. For the service flow, a QOS mechanism is adopted to ensure that each data frame is transmitted and completed in a Packet Delay Budget (PDB) as much as possible. The service flow can include a plurality of IP flows, and the service flow can also be mutually converted with the QOS flow. Thus, all packets of each video frame are received correctly in the PDB, and the decoder of the terminal can correctly decode the video frame.

However, the configuration information of the QOS flow does not distinguish whether the video frame to be transmitted in one period is a data unit of the first data type or a data unit of the second data type. The data amount of the data unit of the first data type is different from the data amount of the data unit of the second data type, so how to reasonably configure the transmission resource to improve the resource utilization rate is an urgent problem to be solved.

Disclosure of Invention

In a first aspect, an embodiment of the present application provides a resource allocation method, including:

Detailed Description

First, some terms in the present application are explained.

(1) Virtual reality technology (VR)

Virtual reality is a computer simulation system that creates and experiences a virtual world, using a computer to create a simulated environment into which a user is immersed. The virtual reality technology utilizes data in real life, and electronic signals generated by the computer technology are combined with various output devices to convert the electronic signals into phenomena which can be felt by people.

(2) Video frame

A video may include one or more still pictures, which are referred to as frames, i.e., video frames. For a VR scene, video data transmission, that is, video frames transmission, is required between a VR device and an application server, each video frame may be composed of a plurality of data packets, and the number of data packets included in different video frames may also be different. For a VR device, a decoder of the VR device can correctly decode an image corresponding to a video frame only when all data packets in the video frame are correctly received within an expected time delay.

The refresh mechanism of the video frame can be two kinds: instantaneous codec Refresh (IDR) and progressive codec Refresh (GDR). Wherein, the IDR belongs to a complete refresh mechanism, that is, each frame of video is completely refreshed by an Intra-Coded Picture (I) frame; GDR belongs to a progressive refresh mechanism, i.e. refresh is done by I slices (Tile) in consecutive multiple Predictive-Coded Picture (P) frames. The slicing refers to a frame Slice obtained by slicing a frame, and the frame Slice obtained by slicing the frame may also be a Slice (Slice), and the Slice is smaller than the slicing. For example, slicing the I frame to obtain I slices. The slicing and slicing operations in the embodiment of the present application are the same, so the implementation method in the embodiment of the present application is described by taking the slicing as an example, and the implementation method for the slicing in the embodiment of the present application is also applicable to the slicing, and is not described in detail.

(2.1) IDR complete Refresh mechanism

In the mechanism, video frames can be I frames and P frames, wherein the I frames are independently coded and decoded in the frames without referring to other frames; and P frames can be encoded with reference to an I frame or to the last P frame. In general, the amount of data included in an I frame is about 10 times the amount of data included in a P frame.

Fig. 1 is a schematic diagram of an output video frame based on an IDR full refresh mechanism. In fig. 1, the device outputs one video frame per P period, the video frame may be an I frame or a P frame, the period for outputting the I frame is n (n is a positive integer, and n is 6 in fig. 1) P periods, and each of the remaining P periods except the P period for outputting the I frame outputs the P frame. Here, the device refers to a terminal device (the terminal device includes a VR device) or an application server device. From the P period when an I frame is output once to the P period before the P period when an I frame is output next time, all video frames in this period may be referred to as a group of video frames, for example, the group of video frames in fig. 1 includes all video frames in the 1 st P period to the 6th P period, and the next group of video frames may include all video frames in the 7 th P period to the 12 th P period.

(2.2) GDR progressive Refresh mechanism

In this mechanism, a video frame may be a P frame including an I slice, and a P slice is also included in the P frame including the I slice. The I slice is coded based on the current slice, and the P slice refers to the I slice or a corresponding P slice in the last P period. When an I frame is divided into m I slices, it means that m P frames including I slices can decode a picture corresponding to an I frame, where each P frame includes m slices, and each P frame includes 1I slice out of m I slices and m-1P slices. It will be appreciated that an I slice of m I slices may correspond to a region in an image, and that the m I slices together make up all regions of the image (i.e., the entire image). In the m P frames including the I slices, the I slices are arranged in order. For example, I slice in the first P frame is in the first slice, I slice in the second P frame is in the second slice, and so on. Each m P frames comprising an I slice, of which m I slices correspond to a picture, may be referred to as a group of video frames. It should be noted that, corresponding to the GDR progressive refresh mechanism, the first video frame output by the device is an I frame, and a P frame including an I slice starts from the second video frame.

Fig. 2a is a schematic diagram of a video frame output based on a GDR progressive refresh mechanism, where the square boxes filled with diagonal patterns in fig. 2a are used to represent I slices, and the remaining square boxes without filled patterns are used to represent P slices. In fig. 2a, the device outputs one video frame every P period, which is a P frame including I slices. In which 4I slices can constitute a picture, and thus, a picture can be decoded every 4P frames including I slices. In fig. 2a, a first slice (P-slice) of a second P-frame may be encoded with reference to a first slice (I-slice) in the first P-frame; a second slice (P slice) in a third P frame may be decoded with reference to a second slice (I slice) in a second P frame; the 2 nd slice (P slice) in the fourth P frame may reference the second slice (P slice encoded) in the third P frame, and so on. All the video frames from the 1 st P period to the 4 th P period in fig. 2a are referred to as a group of video frames.

In one possible implementation, in the mechanism, the video frame may be a P frame including an I slice or a P frame not including an I slice. The P frames not including I slices include m P slices, and the number of P frames not including I slices may be k.

Fig. 2b is a schematic diagram of another video frame output based on the GDR progressive refresh mechanism. In fig. 2b, the device outputs one video frame per P period, which may be a P frame including an I slice and a P frame not including an I slice. In which 4I slices can constitute a picture, and thus, a picture can be decoded every 4P frames including I slices. In fig. 2b, the 1 st to 4 th P periods are 4P frames including I slices, and the 5th to 10 th P periods are 6P frames not including I slices. The 6P frames that do not include I slices may be encoded with reference to the 4P frames that include I slices. Wherein, the 4P frames including I slices and the 6P frames not including I slices can be referred to as a group of video frames.

And S120, the SMF determines the configuration information of the quality of service (QOS) flow according to the service description (PFD) information.

After receiving the PFD information of the service, the SMF may determine which IP flows in the service are mapped to the same QOS flow according to a rule provided by a Policy Control Function (PCF), and determine configuration information of QOS flows corresponding to the QOS flows. In embodiment 100, a service may be mapped to a QOS flow, and therefore, configuration information of a QOS flow corresponding to the service needs to be determined.

The QOS flow carries at least data units of a first data type and data units of a second data type. The data units of the first data type may be I-frames or I-slices and the data units of the second data type may be P-frames or P-slices.

In the embodiment of the application, the QOS flow can be divided into an uplink QOS flow and a downlink QOS flow, and the service can also be divided into an uplink service and a downlink service, wherein the uplink QOS flow corresponds to the uplink service, and the downlink QOS flow corresponds to the downlink service.

The QOS flow and the service can be converted by UPF, that is, UPF can convert the downlink service flow into the downlink QOS flow and can also convert the uplink QOS flow into the uplink service flow. Also, one service may include one or more Internet Protocol (IP) streams. The IP flows included in the downlink service belong to the same session, belong to one or more IP ports, and are obtained by converging a plurality of IP flows through a UPF (unified power flow) according to a Per-flow Filtering and Policing (PSFP) strategy; the IP flows included in the upstream service also belong to one session and belong to one or more ports.

The maximum data size of a data unit of one data type in a period may indicate the maximum data size of the data unit of the data type that needs to be transmitted by the access network device in a period. The Maximum Data size of a Data unit of one Data type in one cycle may be denoted as Maximum Data Volume (MDV) or (P) MDBV, where (P) MDBV may be expressed as Maximum Data burst size (PMDBV) Possible, or may be expressed as MDBV.

When the maximum data amount of a data unit of one data type in one cycle is contained in the corresponding TSCAI cell, the maximum data amount of the data unit of the data type in one cycle may be denoted as PMDBV; when the maximum data amount of a data unit of one data type in one period is included in the corresponding QOS requirement cell, the maximum data amount of the data unit of the data type in one period can be denoted as PMDBV. Of course, in practical applications, whether a certain cell specifically includes a PMDBV or an MDBV may be determined according to specific situations, and the embodiment of the present application is not limited.

It can be understood that, if the data of the first and second data types of the QOS flow indicated by the SMF to the access network device arrives at the base station or the uplink packet arrives at the terminal in the same period, it may be considered that the arrival in the same period indicates that time domain positions overlap.

3) The time when the downlink burst reaches the UPF entry is used to indicate the latest possible time when the last packet in the data burst reaches the UPF entry when the data unit of the first data type is downlink;

4) And (P) MDBV corresponding to the data unit of the first data type, for indicating a maximum data burst amount or a maximum data amount within one period corresponding to the data unit of the first data type that can be transmitted in the PDB.

In this implementation, the information included in the configuration information of the QOS flow may be represented by table 2:

table 2 list of information included in configuration information for QOS flows

Optionally, in this possible implementation manner, the (P) MDBV corresponding to the data unit of the second data type may be an absolute value, or may be a scale factor a, that is, the true (P) MDBV = a (P) MDBV1 of the data unit of the second data type, where the (P) MDBV1 is corresponding to the data unit of the first data type.

Optionally, in this possible implementation, the QOS requirement information element may include a (P) MDBV corresponding to a data unit of the second data type, and accordingly, the first TSCAI information element includes a (P) MDBV corresponding to a data unit of the first data type. That is, data units of one data type may be included in the corresponding TSCAI cell, and data units of another data type may be included in the QOS requirement cell. Except for (P) MDBV, other information included in the first TSCAI cell, the second TSCAI cell, and the QOS requirement cell remains unchanged, and is not described herein. Optionally, at this time, the (P) MDBV corresponding to the data unit of the first data type may be an absolute numerical value, or may be a scale factor b, that is, the true (P) MDBV = (P) MDBV2/b of the data unit of the first data type, where the (P) MDBV2 corresponds to the data unit of the second data type. In this case, the information included in the configuration information of the QOS flow may be represented by table 3:

table 3 list of information included in configuration information for QOS flows

The flow of the service and QOS flows corresponding to tables 2 and 3, and the flow of the PFD information and QOS configuration parameters are shown in fig. 6. Table 2 corresponds to scene 1, and table 3 corresponds to scene 2.

In the embodiment of the present application, if the maximum data size of a data unit in a period is to be set in a QOS requirement cell, the access network device needs to complete sending or receiving the data unit within a specific time delay, and the requirement is strict; if the maximum data size of a data unit within a period is to be set in the TSCAI cell, the access network equipment can finish sending or receiving the data unit within a certain time delay as best as possible. It will be appreciated that the maximum data volume in a QOS requirement cell has a higher priority than the maximum data volume in a TSCAI cell. Therefore, if the priority of a data unit of a certain data type is higher, the maximum data amount of the data unit in one period can be set in the QOS requirement cell, and vice versa, in the TSCAI cell.

It should be noted that, for the two possible implementations described above, if the reference clock of the time provided by the AF is not the clock used by the 5G network, the SMF needs to convert the arrival time and the period into the time of the clock used by the 5G network. Secondly, the SMF also needs to convert the start time of the downlink burst to reach the UPF into the start time of the downlink burst to reach the access network device.

Based on the configuration information of the QOS flow, the access network device may schedule the QOS flow for transmission, and the corresponding step may be any one of S141 to S143, where:

and S141, the access network equipment schedules and transmits the QoS flow according to one of the maximum data volume of the data unit of the first data type in one period and the maximum data volume of the data unit of the second data type in one period.

(1) In one possible implementation, when the QOS flow includes I frames and P frames, the data units of the first data type may be I frames and the data units of the second data type may be P frames. The P frame may specifically be a P frame in the IDR full refresh mechanism shown in fig. 1.

Optionally, the access network device may schedule and transmit the data unit in the period including the first data type data unit in the QOS flow according to the maximum data volume of the data unit of the first data type in one period. That is, for the period with only I frame and no P frame, the access network device schedules the I frame of the QOS flow according to the P (MDBV) of the I frame.

Optionally, for a period with only one P frame and no I frame, the access network device may perform scheduling transmission on data units in the period including the data unit of the second data type in the QOS stream according to the maximum data amount of the data unit of the second data type in one period, that is, perform scheduling transmission on a P frame in the QOS stream according to a (P) MDBV of the P frame.

For example, as shown in fig. 7, for the 2 nd P period to the 5th P period, since only P frames exist in these periods, the access network device may schedule transmission of each P frame of the 2 nd P period to the 5th P period according to the (P) MDBV of the P frame.

(2) In one possible implementation, when only P frames containing I slices in the GDR progressive refresh mechanism exist in the QOS flow, the data unit of the first data type is a P frame containing I slices, and the access network device may schedule transmission of the QOS flow according to a maximum data amount of the data unit of the first data type in one period.

(3) In one possible implementation, when the data unit of the first data type is a P frame including an I slice in the GDR progressive refresh mechanism and the data unit of the second data type is a P frame not including an I slice in the GDR progressive refresh mechanism, the configuration information of the QOS stream includes a (P) MDBV corresponding to the P frame including an I slice and a (P) MDBV corresponding to the P frame not including an I slice. The access network device may schedule transmission of P frames including I slices according to a (P) MDBV corresponding to P frames including I slices and schedule transmission of P frames not including I slices according to a (P) MDBV corresponding to P frames not including I slices.

Optionally, in the GDR progressive refresh mechanism, generally, the first frame of the QOS stream is an I frame, and frames following the first frame I frame are P frames, where the P frames may be P frames including I slices or P frames not including I slices. The SMF may independently configure the time-domain location of the first frame I frame and the (P) MDBV to the access network device. For example, the SMF sends the configuration parameters of another QOS flow to the access network device to indicate the (P) MDBV of the first frame I frame, the time when the downlink burst arrives at the access network device or the time when the uplink burst arrives at the terminal.

Optionally, in the GDR progressive refresh mechanism, in a QOS flow, which periods are P frames including I slices and which periods are P frames not including I slices, the access network device may determine an occurrence period of a P frame including an I slice and an occurrence period of a P frame not including an I slice by a starting position of a P frame including an I slice, a period N of a P frame including an I slice at the starting position, and a total number M of slices of one P frame. The starting position of the P frame including the I slice refers to a time domain position where a first P frame including the I slice is located in a plurality of adjacent P frames including the I slice. The N and M values may be signaled by the SMF to the access network equipment via configuration QOS parameters, and may be carried in TSCAI cells.

For example, as shown in fig. 2b, one P frame includes a total number of slices of 4, so M =4. And, of every 10P frames, the first 4P frames are P frames including I slices, and the 5th to 10 th P frames are P frames not including I slices, so N =10. The QOS flow may then cycle through 4P frames that include I slices, followed by 6P frames that do not include I slices. At this time, the first data type is a P frame including an I slice, the second data type is a P frame not including an I slice, and the access network device may schedule and transmit P frames including an I slice from a 1 st P period to a 4 th P period according to a (P) MDBV corresponding to the P frame including an I slice; p frames not including I slices of the 5th to 10 th P periods may be scheduled for transmission according to a (P) MDBV corresponding to the P frames not including I slices.

And S142, the access network equipment carries out scheduling transmission on the QOS flow according to the maximum data volume of the data unit of the first data type in one period and the maximum value of the maximum data volume of the data unit of the second data type in one period at the time domain position where the data unit of the first data type and the data unit of the second data type are overlapped.

Wherein the data unit of the first data type may be an I frame and the data unit of the second data type may be a P frame. In this case, the access network device may schedule transmission of the QOS stream according to a maximum value of a maximum data amount of the data units of the first data type in one period and a maximum data amount of the data units of the second data type in one period at a time domain position where the data units of the first data type overlap with the data units of the second data type. Wherein the time domain position may be comprised within a period in which a data unit of the first data type overlaps with a data unit of the second data type. And the access network device specifically performs scheduling transmission on the data unit in the period of the QOS stream according to the maximum data amount of the data unit of the first data type in the period and the maximum value of the maximum data amount of the data unit of the second data type in the period, where the data unit of the first data type and the data unit of the second data type overlap.

Alternatively, in an IDR full refresh scheme, I-frames typically occur in the first P-cycle. The SMF may explicitly configure the access network device with the first data type in the first TSCAI cell and the second data type in the second TSCAI cell independently. Optionally, in the IDR complete refresh mechanism, for a QOS flow, which periods are I frames and which periods are P frames, the access network device can determine the position where an I frame (not including a P frame) appears by including the start position of the I frame and including the I frame period N. For example, after the SMF sends the configuration information of the QOS flow to the access network device, the access device determines that the first TSCAI cell of the QOS flow corresponds to the I frame, the second TSCAI cell corresponds to the P frame, and at the position where the I frame appears, it is considered that the P frame does not appear, that is, the position where the P frame appears can be determined according to the second TSCAI cell and the first TSCAI cell.

In a possible implementation manner, optionally, the access network device may further receive association indication information, determine that data of the first TSCAI cell and the second TSCAI cell belong to the same PDU session or multi-stream data of the same service, and the access network device determines time domain positions where an I frame and a P frame appear according to the association indication information and the configurations of the first TSCAI cell and the second TSCAI cell, and schedules and transmits the service according to (P) MDBV of each TSCAI cell.

For example, as shown in fig. 7, which is a schematic diagram of sending an output video frame based on an IDR complete refresh mechanism, after receiving configuration information, an access network device determines that a period of a first data type data unit, i.e., an I frame, is 6P periods, and a period of a second data type data unit, i.e., a P frame, is 1P period. That is, P frames are transmitted once every P period, and I frames are transmitted once every 6P periods. Then, the access network device may determine that the I frame and the P frame overlap in the P period, considering that the P frame needs to be transmitted in the P period in which the I frame is transmitted. As shown in fig. 7, the access network device determines that it needs to send an I frame and also needs to send a P frame in the first P period, and therefore, it may be considered that the I frame and the P frame overlap in the first P period. In fact, as shown in fig. 1, the P period for sending I frames has no P frames, but the access network device mistakenly has I frames and P frames for the first P period. Accordingly, the access network device may determine the maximum of the (P) MDBV of the I frame and the (P) MDBV of the P frame to allocate to schedule transmission for the traffic at the time of the P period. Assuming that the (P) MDBV for the I-frame is 10mb and the (P) MDBV for the P-frame is 1MB, at the temporal location where the I-frame and the P-frame overlap, the access network device schedules transmission of the I-frame in the QOS stream according to the (P) MDBV for the I-frame, i.e., 1 MB.

And S143, the access network equipment carries out scheduling transmission on the QOS flow according to the data volume of the sum of the maximum data volume of the data unit of the first data type in one period and the maximum data volume of the data unit of the second data type in one period at the time domain position where the data unit of the first data type and the data unit of the second data type are overlapped.

The data unit of the first data type may be an I slice, and the data unit of the second data type may be a P slice. In this case, the access network device may schedule transmission of the QOS stream according to a data amount that is a sum of a maximum data amount of the data unit of the first data type in one period and a maximum data amount of the data unit of the second data type in one period at a time domain position where the data unit of the first data type overlaps with the data unit of the second data type. And the access network device specifically performs scheduling transmission on the data units in the period in the QOS flow according to the data volume of the sum of the maximum data volume of the data units of the first data type in one period and the maximum data volume of the data units of the second data type in one period in a period in which the data units of the first data type and the data units of the second data type overlap.

For example, as shown in fig. 2a, after receiving the configuration information, the access network device determines that the period of the data unit of the first data type, i.e., the I slice, is 1P period, and the period of the data unit of the second data type, i.e., the P slice, is also 1P period. Therefore, the access network device may determine that the I-slice and the P-slice are overlapped in each period, and may schedule and transmit the QOS stream with a value of a sum of a (P) MDBV corresponding to the I-slice and a (P) MDBV corresponding to the P-slice in each period. As shown in fig. 2a, if there are 3P slices in a cycle, then the (P) MDBV corresponding to the P slice corresponds to the 3P slices. Assuming that the (P) MDBV of the I-slice is 0.5MB and the (P) MDBV of the P-slice is 1MB, since the I-slice and the P-slice are overlapped at each period, the access network device schedules transmission of a P frame including the I-slice according to the sum of the (P) MDBV of the I-slice and the (P) MDBV of the P-slice, i.e., 1.5 MB.

The scheduled transmission in the embodiments of the present application may be dynamic scheduling, pre-configured grant, or semi-static scheduling. Each scheduling transmission mode may support the maximum data burst size of the corresponding data unit to be transmitted, which is not limited in the embodiment of the present application. The dynamic scheduling refers to that the access network equipment performs resource allocation for the terminal equipment according to the wireless link state of an uplink channel and a downlink channel; the pre-configuration of authorization means that the access network equipment allocates resources to the terminal equipment in advance; the semi-static scheduling mode is that the access network equipment indicates the current scheduling information of the terminal equipment through the PDCCH in the initial scheduling, and the terminal equipment identifies the semi-static scheduling, stores the current scheduling information, and receives and transmits services at the same time-frequency resource position every fixed period.

It should be noted that the access network device does not need to perform all the steps of embodiments S141 to S143, and the steps that need to be performed may be determined according to the data type of the data unit. Specifically, when the QOS flow includes an I frame and a P frame, S141 and S142 need to be performed; when the QOS flow only has a P frame including an I slice, S143 needs to be executed; when there are both P frames including I slices and P frames not including I slices in the QOS stream, S141 needs to be executed.

In addition, the access network device specifically schedules and transmits the QOS stream according to a maximum value, that is, a maximum value, in a maximum data volume of a first data type data unit in one period and a maximum data volume of a second data type data unit in the same period, or schedules and transmits the QOS stream according to a sum of the maximum data volume and the maximum data volume, that is, an accumulation manner, of the first data type data unit and the second data type data unit, which may be implicitly indicated to the access network by the SMF. For example, the indication is made through a PDU session resource establishment request, or a PDU session resource modification request, or a data type carried by a handover request signaling.

For example, when the first TSCAI in the signaling indicates that the data unit of the first data type is an I frame and the second TSCAI indicates that the data unit of the second data type is a P frame, the access network device schedules the QOS flow by taking the maximum value.

For another example, when the first TSCAI indicates that the data unit of the first data type is an I slice, and the second TSCAI indicates that the data unit of the second data type is a P slice, the access network device schedules and transmits the QOS flow in an accumulation manner.

Optionally, the access network device specifically schedules and transmits the QOS stream according to a maximum value, that is, a maximum value, in a period of the maximum data volume of the data unit of the first data type and a maximum value, that is, a maximum value, of the maximum data volume of the data unit of the second data type in the same period, or schedules and transmits the QOS stream according to a sum of the maximum data volume and the maximum data volume, that is, an accumulation manner, where the schedule and transmission may be explicitly indicated to the access network device by the SMF. For example, the SMF indicates the type of data carried by a PDU session resource establishment request, a PDU session resource modification request, or a handover request signaling.

For example, the TSCAI information element in the signaling carries an indication information for indicating a time domain position where all uplink data units or all downlink data units of the QOS flow overlap, and selects a maximum value mode or an accumulation mode to schedule and transmit the QOS flow by combining data units of different data types.

As can be seen from the foregoing embodiment 100, when the QOS stream includes I frames and P frames, the access network device may schedule transmission of the I frames according to the (P) MDBV corresponding to the I frames in the period including only the I frames, and schedule transmission of the P frames according to the (P) MDBV corresponding to the P frames in the period including the P frames. Therefore, when the access network equipment carries out scheduling transmission, different resources are allocated to different data units, the allocated resources are closer to the required data volume for transmission, and the utilization rate of the resources is improved. When the QOS stream has both P frames including I slices and P frames not including I slices, on one hand, the access network equipment performs scheduling transmission on the P frames including I slices according to the I slices and the (P) MDBV of the P slices, and can perform differential reliability guarantee transmission on the I slice part and the P slice part; on the other hand, the access network device schedules transmission of P frames not including I slices according to the (P) MDBV of P frames not including I slices. Different resources are distributed to different data units, and the distributed resources are closer to the required data volume for transmission, so that the access network equipment reasonably configures the transmission resources and improves the utilization rate of the resources.

The embodiment of the present application further provides a resource allocation method 200, which is applicable to the communication system shown in fig. 3. Fig. 8 is a flow chart illustrating a method 200 for resource allocation. The resource allocation method 200 is illustrated from the perspective of interaction between the SMF in the core network and the access network equipment. In the embodiment of the application, signaling interaction is performed between the SMF and the terminal device. The resource allocation method 200 differs from the resource allocation method 100 in that one service in the resource allocation method 100 may correspond to one QOS flow, and one service in the resource allocation method 200 may correspond to two QOS flows.

The resource allocation method 200 includes, but is not limited to, the following steps:

s210. The SMF receives service description PFD information from the application function AF.

In this method, the relevant content of S210 can be referred to as the relevant description of S110 in the resource allocation method 100, and is not described in detail here.

And S220, the SMF determines the configuration information of the quality of service (QOS) flow according to the service description (PFD) information.

After receiving the PFD information of the service, the SMF may determine which IP flows in the service are mapped to the same QOS flow according to rules provided by the PCF, and determine configuration information of QOS flows corresponding to each QOS flow. In embodiment 200, a service is mapped to 2QOS flows, and therefore configuration information of a first QOS flow and configuration information of a second QOS flow corresponding to the service need to be determined.

S230, the access network equipment receives configuration information of a first QOS flow and configuration information of a second QOS flow, wherein the first QOS flow bears a data unit of a first data type, and the second QOS flow bears a data unit of a second data type; the configuration information for the first QOS flow includes a maximum amount of data for the data units of the first data type in one period, and the configuration information for the second QOS flow includes a maximum amount of data for the data units of the second data type in one period.

And the configuration information of the first QOS flow and the configuration information of the second QOS flow are transmitted by the SMF. The SMF can send the information to the access network equipment by a PDU session resource establishment request or a PDU session resource modification request and a switching request signaling.

In the embodiment of the application, the first QOS flow can be divided into an uplink first QOS flow and a downlink first QOS flow; the second QOS flow can be divided into an uplink second QOS flow and a downlink second QOS flow, and the service can also be divided into an uplink service and a downlink service, wherein the uplink first QOS flow and the uplink second QOS flow correspond to the uplink service, and the downlink first QOS flow and the downlink second QOS flow correspond to the downlink service. The data flow direction of the downlink first QOS flow or the downlink second QOS flow is as follows: UPF → RAN → terminal equipment; the data flow direction of the uplink first QOS flow or the uplink second QOS flow is as follows: terminal → RAN → UPF. Whether uplink QOS flow or downlink QOS flow, the flow direction of their respective corresponding configuration information is AF → SMF → RAN. The first QOS flow and the second QOS can be mutually converted with the service through UPF, namely the UPF can convert the downlink service into the downlink first QOS flow and the downlink second QOS flow and can also convert the uplink first QOS flow and the uplink second QOS flow into the uplink service. Moreover, one service may include one or more IP flows, and the IP flows included in the downlink service belong to the same session, belong to the same or different ports, and are obtained by aggregating a plurality of IP flows by the UPF according to the PSFP policy; the IP flows included in the upstream service also belong to one session.

The maximum data volume of a data unit of one data type in one period may represent the maximum data volume of the data unit of the data type that needs to be transmitted by the access network device in one period. The maximum data size of a data unit of one data type in one cycle may be denoted as (P) MDBV, which may be denoted as PMDBV or MDBV.

When the maximum data amount of a data unit of one data type in one period is contained in the corresponding TSCAI cell, the maximum data amount of the data unit of the data type in one period can be denoted as PMDBV; when the maximum data amount of a data unit of one data type in one period is included in the corresponding QOS requirement cell, the maximum data amount of the data unit of the data type in one period can be denoted as PMDBV. Of course, in practical applications, whether a certain cell specifically includes a PMDBV or an MDBV may be determined according to specific situations, and the embodiment of the present application is not limited.

That is, data units of one data type may be included in the corresponding TSCAI cells, and data units of another data type may be included in their corresponding QOS requirement cells. Except for (P) MDBV, other information included in the first TSCAI cell, the second TSCAI cell, the first QOS requirement cell, and the second QOS requirement cell remains unchanged, which is not described herein. In this implementation, the information included in the configuration information of the first QOS flow and the configuration information of the second QOS flow may be represented by table 6:

table 6 list of information included in configuration information for a first QOS flow and a second QOS flow

The flows of the service and the two QOS flows corresponding to tables 5 and 6, and the flows of the PFD information and the first and second QOS configuration parameters are shown in fig. 10. Table 5 corresponds to scene 1, and table 6 corresponds to scene 2.

It should be noted that, after receiving the first QOS flow and the second QOS flow, the access network device needs to perform scheduling transmission on both the first QOS flow and the second QOS flow, so when the access network device performs scheduling transmission on both the first QOS flow and the second QOS flow, the first QOS flow and the second QOS flow may include an I frame and a P frame, or may include a P frame that does not include an I slice and a P frame that includes an I slice.

For the two possible implementations described above, if the reference clock of the time provided by the AF is not the clock used by the 5G network, the SMF needs to convert the arrival time, the period, to the time of the clock used by the 5G network. Secondly, the SMF also needs to convert the start time of the downlink burst to reach the UPF into the start time of the downlink burst to reach the access network device.

Based on the configuration information of the first QOS flow and the configuration information of the second QOS flow, the access network device may schedule and transmit the service, and the corresponding step may be at least one of S241 to S243, where:

and S241, the access network equipment carries out scheduling transmission on the service according to the maximum data volume of the data unit of the first data type in one period and the maximum data volume of the data unit of the second data type in one period.

Optionally, the access network device may schedule, according to the maximum data amount of the data unit of the first data type in one period, the data unit of the QOS stream in the period including the data unit of the first data type for transmission. That is, for the period with only I frame and no P frame, the access network device schedules the I frame of the QOS flow according to the P (MDBV) of the I frame.

For example, as shown in fig. 7, for the 2 nd to 5th P periods, since there are only P frames in these periods, the access network device may schedule transmission of the P frames from the 2 nd to 5th P periods according to the P frame (P) MDBV.

(3) In one possible implementation, when the data unit of the first data type is a P frame including an I slice in the GDR progressive refresh mechanism and the data unit of the second data type is a P frame not including an I slice in the GDR progressive refresh mechanism, the configuration information of the QOS stream includes a (P) MDBV corresponding to the P frame including an I slice and a (P) MDBV corresponding to the P frame not including an I slice. The access network device may schedule transmission of the P frame including the I slice according to a (P) MDBV corresponding to the P frame including the I slice, and schedule transmission of the P frame not including the I slice according to a (P) MDBV corresponding to the P frame not including the I slice.

Optionally, in the GDR progressive refresh mechanism, in a QOS flow, which periods are P frames including I slices and which periods are P frames not including I slices, the access network device may determine an occurrence period of a P frame including an I slice and an occurrence period of a P frame not including an I slice by a starting position of a P frame including an I slice, a period N of a P frame including an I slice at the starting position, and a total number M of slices of one P frame. The starting position of a P frame including an I slice refers to a time domain position where a first P frame including an I slice is located in a plurality of adjacent P frames including an I slice. The N and M values may be signaled by the SMF to the access network equipment via configuration QOS parameters, and may be carried in TSCAI cells.

For example, as shown in fig. 2b, one P frame includes a total number of slices of 4, so M =4. And, of every 10P frames, the first 4P frames are P frames including I slices, and the 5th to 10 th P frames are P frames not including I slices, so N =10. The QOS flow may then cycle through 4P frames that include I slices, followed by 6P frames that do not include I slices. At this time, the first data type is a P frame including an I slice, the second data type is a P frame not including an I slice, and the access network device may schedule and transmit the P frames including an I slice in the 1 st P period to the 4 th P period according to a (P) MDBV corresponding to the P frame including an I slice; p frames not including I slices of the 5th to 10 th P periods may be scheduled for transmission according to a (P) MDBV corresponding to the P frames not including I slices.

And S242, the access network equipment performs scheduling transmission on the service according to the maximum value in the maximum data volume of the data unit of the first data type in a period and the maximum value in the maximum data volume of the data unit of the second data type in the period at the time domain position where the data unit of the first data type and the data unit of the second data type are overlapped.

Wherein the data unit of the first data type may be an I frame and the data unit of the second data type may be a P frame. In this case, the access network device may schedule transmission of the service according to a maximum value of a maximum data amount of the data unit of the first data type in one period and a maximum data amount of the data unit of the second data type in the same period at a time domain position where the data unit of the first data type and the data unit of the second data type overlap. Wherein the time domain position may be comprised within a period in which data units of the first data type overlap with data units of the second data type. And the access network device specifically performs scheduling transmission on the data unit in the service in the type of cycle according to the maximum data volume of the data unit of the first data type in one cycle and the maximum value of the maximum data volume of the data unit of the second data type in the same cycle in a cycle in which the data unit of the first data type and the data unit of the second data type overlap.

Alternatively, in an IDR full refresh scheme, an I-frame typically occurs in the first P-cycle. The SMF may explicitly configure the access network device independently with data units in the first QOS flow as a first data type and with data units in the second QOS flow as a second data type. Optionally, in the IDR complete refresh mechanism, for which periods of the first QOS flow are I frames and which periods of the second QOS flow are P frames, the access network device can determine the position where the I frame (not including the P frame) appears by including the start position of the I frame and including the I frame period N. For example, after the SMF sends the configuration information of the first QOS flow and the configuration information of the second QOS flow to the access network device, the access device determines that the first QOS flow includes an I frame and the second QOS flow includes a P frame, and determines that the P frame does not appear at the position where the I frame appears, that is, the position where the P frame appears according to the second TSCAI cell and the first TSCAI cell.

In a possible implementation manner, optionally, the access network device may further receive association indication information, determine that data of the first QOS flow and the second QOS flow belong to the same PDU session or multi-stream data of the same service, and the access network device determines, according to the association indication information and the configurations of the first QOS flow and the second QOS flow, time domain positions where an I frame and a P frame appear, and schedules and transmits the QOS flows according to (P) MDBV of each QOS flow.

For example, a first QOS flow sets first association indication information, and a second QOS flow also sets the first association indication information, then the first QOS flow and the second QOS flow having the same first association indication may be considered to belong to the same PDU session, or multi-flow data of the same service.

For example, as shown in fig. 7, after receiving the configuration information of the first QOS flow and the configuration information of the second QOS flow, the access network device determines that the period of the data unit of the first data type, i.e., the I frame, is 6P periods, and the period of the data unit of the second data type, i.e., the P frame, is 1P period. That is, P frames are transmitted once every P period, and I frames are transmitted once every 6P periods. Then, the access network device may determine that the I frame and the P frame overlap in the P period, considering that the P frame needs to be transmitted in the P period in which the I frame is transmitted. As shown in fig. 7, the access network device determines that it needs to send an I frame and also needs to send a P frame in the first P period, and therefore, it may be considered that the I frame and the P frame overlap in the first P period. Actually, as shown in fig. 1, there is no P frame in the P period for sending the I frame, but the access network device mistakenly has the I frame and the P frame for the first P period. Accordingly, the access network device may determine a maximum of the (P) MDBV of the I frame and the (P) MDBV of the P frame to allocate to scheduling transmission for the traffic at the time of the P period. Assuming that the (P) MDBV for the I-frame is 10mb and the (P) MDBV for the P-frame is 1MB, at the temporal location where the I-frame and the P-frame overlap, the access network device schedules transmission of the I-frame in the QOS stream according to the (P) MDBV for the I-frame, i.e., 1 MB.

And S243, the access network equipment schedules and transmits the service by the data volume of the sum of the maximum data volume of the data unit of the first data type in one period and the maximum data volume of the data unit of the second data type in one period at the time domain position where the data unit of the first data type and the data unit of the second data type are overlapped.

The data unit of the first data type may be an I slice, and the data unit of the second data type may be a P slice. In this case, the access network device may schedule transmission of the first QOS flow and the second QOS flow according to a data volume of a sum of a maximum data volume of the data units of the first data type in one period and a maximum data volume of the data units of the second data type in one period at a time domain position where the data units of the first data type overlap with the data units of the second data type, that is, schedule transmission of the respective QOS flows according to the maximum data volumes of the respective QOS flows. And the access network device specifically performs scheduling transmission on the data units in the first QOS flow and the second QOS flow in the period where the data units of the first data type and the second data type overlap, according to the data volume of the sum of the maximum data volume of the data units of the first data type in one period and the maximum data volume of the data units of the second data type in one period.

For example, as shown in fig. 2a, after receiving the configuration information, the access network device determines that the period of the first data type data unit, that is, the I fragment, is 1P period, and the period of the second data type data unit, that is, the P fragment, is also 1P period. Therefore, the access network device may determine that the I-slice and the P-slice overlap in each period, and may schedule and transmit the first QOS stream and the second QOS stream with the value of the sum of the (P) MDBV corresponding to the I-slice and the (P) MDBV corresponding to the P-slice in each period. As shown in fig. 2a, if there are 3P slices in a cycle, then the (P) MDBV corresponding to the P slice corresponds to the 3P slices. Assuming that the I-sliced (P) MDBV is 0.5MB and the P-sliced (P) MDBV is 1MB, since the I-slice and the P-slice overlap at each period, the access network device schedules transmission of a P frame including the I-slice according to the sum of the I-sliced (P) MDBV and the P-sliced (P) MDBV, i.e., 1.5 MB.

In a possible implementation manner, optionally, the access network device may further receive indication information, where the indication information may indicate that the first QOS flow and the second QOS flow belong to the same Protocol Data Unit (PDU) Session (Session) or belong to the same service.

The scheduled transmission in the embodiments of the present application may be a pre-configured grant, semi-static scheduling, or dynamic scheduling. Each scheduling transmission mode may support the maximum data burst size of the corresponding data unit to be transmitted, which is not limited in the embodiment of the present application.

It should be noted that the access network device does not need to perform all the steps of embodiments S241 to S243, and the steps that need to be performed may be determined according to the data type of the data unit. Specifically, when the first QOS flow includes I frames and the second QOS flow includes P frames, S241 and S242 need to be performed; when the second QOS flow only has P frames including I slices, S243 needs to be executed; when the first QOS flow and the second QOS flow are scheduled together, when there is both a P frame including an I slice and a P frame not including an I slice, S241 needs to be performed.

In addition, the access network device specifically schedules and transmits the QOS stream according to a maximum value, that is, a maximum value, in a maximum data volume of a first data type data unit in one period and a maximum data volume of a second data type data unit in the same period, or schedules and transmits the QOS stream according to a sum of the maximum data volume and the maximum data volume, that is, an accumulation manner, of the first data type data unit and the second data type data unit, which may be implicitly indicated to the access network by the SMF. For example, the indication is indicated by a PDU session resource establishment request, or a PDU session resource modification request, or a data type carried by a handover request signaling. For example, when the first TSCAI in the signaling indicates that the data unit of the first data type is an I frame and the second TSCAI indicates that the data unit of the second data type is a P frame, the access network device schedules the first QOS flow and the second QOS flow by taking the maximum value. For another example, when the first TSCAI indicates that the data unit of the first data type is an I slice and the second TSCAI indicates that the data unit of the second data type is a P slice, the access network device schedules the first QOS flow and the second QOS flow in an accumulation manner.

Optionally, the access network device specifically schedules the QOS stream according to a maximum value, that is, a maximum value, in the maximum data amount in one period of the data unit of the first data type and a maximum value, that is, a maximum value, in the maximum data amount in the same period of the data unit of the second data type, or schedules the QOS stream according to a sum of the maximum value and the maximum value, that is, an accumulation manner, and may explicitly indicate, by the SMF, to the access network. For example, the indication is made through a PDU session resource establishment request, or a PDU session resource modification request, or a data type carried by a handover request signaling. Namely, the TSCAI in the signaling carries an indication information for indicating the time domain position where all uplink data units or all downlink data units overlap in the first and second QOS flows, and selects a maximum value mode or an accumulation mode to schedule and transmit the QOS flow by combining data units of different data types.

As can be seen from the foregoing embodiment 200, when the first QOS flow includes I frames and the second QOS flow includes P frames, the access network device may schedule transmission of the I frames according to the (P) MDBV corresponding to the I frames in the period with the I frames, and schedule transmission of the P frames according to the (P) MDBV corresponding to the P frames in the period with the P frames. Therefore, when the access network equipment carries out scheduling transmission, different resources are allocated to different data units, the allocated resources are closer to the required data volume for transmission, and the utilization rate of the resources is improved. When the first QOS flow comprises I fragments and the second QOS flow comprises P fragments, on one hand, the access network equipment carries out scheduling transmission on P frames comprising the I fragments according to the I fragments and the (P) MDBV of the P fragments; on the other hand, the access network equipment schedules and transmits the P frame without the I fragment according to the (P) MDBV of the P frame without the I fragment, and also realizes that different resources are allocated to different data units, and the allocated resources are closer to the data volume required to be transmitted, so the access network equipment reasonably allocates transmission resources, and the utilization rate of the resources is improved.

The embodiment of the present application further provides a resource allocation method 300, which is applicable to the communication system shown in fig. 3. Fig. 11 is a flow chart illustrating a resource allocation method 300. The resource allocation method 300 is illustrated from the perspective of interaction between SMF in the core network and access network equipment. The resource allocation method 300 differs from the resource allocation method 200 in that one service in the resource allocation method 200 can correspond to two QOS flows, and one service in the resource allocation method 300 can correspond to 4 QOS flows. The resource allocation method 300 includes, but is not limited to, the following steps:

and S310, receiving service description (PFD) information from an Application Function (AF) by the SMF.

In this method, the relevant content of S310 can be referred to as the relevant description of S110 in the resource allocation method 100, and is not described in detail here.

And S320, the SMF determines the configuration information of the QOS flow according to the PFD information.

After receiving the PFD information of the service, the SMF may determine which IP flows in the service are mapped to the same QOS flow according to rules provided by the PCF, and determine configuration information of QOS flows corresponding to each QOS flow. In embodiment 200, a service is mapped to 3QOS flows, and thus configuration information of a first QOS flow, configuration information of a second QOS flow, configuration information of a third QOS flow, and configuration information of a fourth QOS flow corresponding to the service need to be determined.

S330, the access network equipment receives configuration information of a first QOS flow, configuration information of a second QOS flow, configuration information of a third QOS flow and configuration information of a fourth QOS flow, wherein the first QOS flow bears an uplink data unit of a first data type, and the second QOS flow bears an uplink data unit of a second data type; the third QOS flow bears the downlink data unit of the first data type, and the fourth QOS flow bears the downlink data unit of the second data type; the configuration information of the first QOS flow comprises the maximum data volume of the uplink data unit of the first data type in one period, and the configuration information of the second QOS flow comprises the maximum data volume of the uplink data unit of the second data type in one period; the configuration information of the third QOS flow includes a maximum data amount of the downlink data unit of the first data type within one period, and the configuration information of the fourth QOS flow includes a maximum data amount of the downlink data unit of the second data type within one period.

Wherein, the configuration information of the first QOS flow, the configuration information of the second QOS flow, the configuration information of the third QOS flow and the configuration information of the fourth QOS flow are transmitted by SMF and aim at the same PDU conversation or the same service. The SMF may send the information to the access network device by signaling.

The configuration information of the first QOS flow comprises a first TSCAI cell and a first QOS demand cell; the configuration information of the second QOS flow comprises a second TSCAI cell and a second QOS demand cell; the configuration information of the third QOS flow comprises a third TSCAI cell and a third QOS demand cell; the configuration information of the fourth QOS flow includes a fourth TSCAI information element and a fourth QOS demand information element.

It should be noted that after receiving the first QOS flow and the second QOS flow, or the third QOS flow and the fourth QOS flow, the access network device needs to schedule and transmit the two flows together, so that the access network device still performs scheduling and transmission on the two flows in the manner shown in fig. 2a, fig. 2b, or fig. 7.

In one possible implementation, the first QOS-requirement cell includes a maximum amount of data of the uplink data unit of the first data type in one period; the second QOS requirement cell includes a maximum data amount of the uplink data unit of the second data type in one period; the third QOS requirement cell includes a maximum data amount of the downlink data unit of the first data type in one period; the fourth QOS-requirement cell includes a maximum amount of data of the downstream data unit of the second data type within one period.

In this implementation, the information included in the configuration information of the first QOS flow, the configuration information of the second QOS flow, the configuration information of the third QOS flow, and the configuration information of the fourth QOS flow may be represented by table 7:

table 7 list of information included in configuration information of first to fourth QOS flows

The flows of the services and 4 QOS flows corresponding to this table 7, and the flows of the PFD information and the first to fourth QOS configuration parameters are as shown in fig. 12.

The access network equipment can determine a first QOS flow configuration parameter according to the uplink PFD1 information; determining a second QOS flow configuration parameter according to the uplink PFD2 information; determining a third QOS flow configuration parameter according to the downlink PFD1 information; determining a fourth QOS flow configuration parameter according to the downlink PFD2 information.

In one possible implementation, the first QOS-requirement cell includes a maximum amount of data of the uplink data unit of the first data type in one period; the second TSCAI cell comprises the maximum data volume of the uplink data unit of the second data type in one period; the third QOS requirement cell includes a maximum data amount of the downlink data unit of the first data type in one period; the fourth TSCAI cell comprises a maximum amount of data of the downlink data unit of the second data type within one period.

In this implementation, the information included in the configuration information of the first QOS flow, the configuration information of the second QOS flow, the configuration information of the third QOS flow, and the configuration information of the fourth QOS flow may be represented by table 8:

table 8 list of information included in configuration information of first to fourth QOS flows

In one possible implementation, the first TSCAI information element includes a maximum data amount of the uplink data unit of the first data type within one period; the second QOS requirement cell indicates a maximum data amount of the uplink data unit of the second data type in one period; the third TSCAI cell comprises a maximum data amount of the downlink data unit of the first data type within one period; the fourth QOS requirement parameter includes a maximum amount of data of the downlink data unit of the second data type within one period.

In this implementation, the information included in the configuration information of the first QOS flow, the configuration information of the second QOS flow, the configuration information of the third QOS flow, and the configuration information of the fourth QOS flow may be represented by table 9:

table 9 list of information included in configuration information of first to fourth QOS flows

The flows of the services and 4 QOS flows corresponding to tables 8 and 9, and the flows of the PFD information and the first to fourth QOS configuration parameters are shown in fig. 13.

The access network equipment can determine a first QOS flow configuration parameter according to the uplink PFD1 information; determining a second QOS flow configuration parameter according to the uplink PFD2 information; determining a third QOS flow configuration parameter according to the downlink PFD1 information; determining a fourth QOS flow configuration parameter according to the downlink PFD2 information. Table 8 corresponds to scene 1, and table 9 corresponds to scene 2.

Based on the configuration information of the first QOS flow, the configuration information of the second QOS flow, the configuration information of the third QOS flow, and the configuration information of the fourth QOS flow, the access network device may schedule and transmit the service, and the corresponding steps may be S341 to S346, where:

and S341, the access network equipment schedules and transmits the service according to the maximum data volume of the uplink data unit of the first data type in one period and the maximum data volume of the uplink data unit of the second data type in one period.

S342, the access network equipment schedules and transmits the service according to the maximum data volume of the downlink data unit of the first data type in one period and the maximum data volume of the downlink data unit of the second data type in one period; or alternatively.

And S343, the access network equipment schedules and transmits the service according to the maximum value in the maximum data volume of the uplink data unit of the first data type in a period and the maximum data volume of the uplink data unit of the second data type in a period at the time domain position where the uplink data unit of the first data type and the uplink data unit of the second data type are overlapped.

And S344, the access network device schedules and transmits the service according to the maximum data volume of the downlink data unit of the first data type in one period and the maximum value of the maximum data volume of the downlink data unit of the second data type in one period at the time domain position where the downlink data unit of the first data type and the downlink data unit of the second data type are overlapped.

And S345, the access network equipment schedules and transmits the service according to the data volume of the sum of the maximum data volume of the uplink data unit of the first data type in one period and the maximum data volume of the uplink data unit of the second data type in one period at the time domain position where the uplink data unit of the first data type and the uplink data unit of the second data type are overlapped.

S346, the access network device performs scheduling transmission on the service according to the data volume of the sum of the maximum data volume of the downlink data unit of the first data type in one period and the maximum data volume of the downlink data unit of the second data type in one period at the time domain position where the downlink data unit of the first data type and the downlink data unit of the second data type overlap.

In a possible implementation manner, the access network device may further receive indication information, where the indication information may indicate that the first QOS flow, the second QOS flow, the third QOS flow, and the fourth QOS flow belong to the same PDU Session or belong to the same service.

The scheduled transmission in the embodiments of the present application may be a pre-configured grant, semi-static scheduling, or dynamic scheduling. Each scheduling transmission mode can support the maximum data burst size of the corresponding data unit to be transmitted, which is not limited in the embodiment of the present application.

It should be noted that the access network device does not need to perform all the steps of embodiments S341 to S346, and the corresponding steps that need to be performed may be determined according to the data type of the data unit. Specifically, when the first QOS flow includes I frames and the second QOS flow includes P frames, S341 and S343 need to be performed; when the third QOS flow includes I frames and the fourth QOS flow includes P frames, S342 and S344 need to be performed. When the second QOS flow has only P frames including I slices, S345 needs to be executed; when the fourth QOS flow has only P frames comprising I slices, S346 needs to be performed. When the first QOS flow and the second QOS flow have both P frames including I slices and P frames not including I slices, S341 needs to be executed; when there are both P frames including I-slices and P frames not including I-slices in the third QOS flow and the fourth QOS flow, S342 needs to be executed.

As can be seen from the foregoing embodiment 300, when the first QOS flow includes I frames and the second QOS flow includes P frames, or the third QOS flow includes I frames and the fourth QOS flow includes P frames, the access network device may schedule the I frames for transmission according to the (P) MDBV corresponding to the I frames in the period where the I frames exist, and schedule the P frames for transmission according to the (P) MDBV corresponding to the P frames in the period where the P frames exist. Therefore, when the access network equipment carries out scheduling transmission, different resources are allocated to different data units, the allocated resources are closer to the required data volume for transmission, and the utilization rate of the resources is improved. When the first QOS flow comprises an I fragment and the second QOS flow comprises a P fragment, or the third QOS flow comprises an I fragment and the fourth QOS flow comprises a P fragment, on one hand, the access network equipment carries out scheduling transmission on a P frame comprising the I fragment according to the I fragment and a (P) MDBV of the P fragment; on the other hand, the access network equipment schedules and transmits the P frame without the I fragment according to the (P) MDBV of the P frame without the I fragment, and also realizes that different resources are allocated to different data units, and the allocated resources are closer to the data volume required to be transmitted, so the access network equipment reasonably allocates transmission resources, and the utilization rate of the resources is improved.
