Description

Technical Field

[0001] The present application relates to the field of extended reality (XR), and in particular to a data processing method, related equipment and a communication system. Background Art

[0002] In XR services, the application server sends the data stream of the XR service to the user plane function (UPF) entity, and the UPF entity then forwards these data streams to the radio access network (RAN) equipment, and finally the RAN equipment sends these data streams to the user equipment. Since the data stream output by the application server may contain some data streams that do not need to be transmitted to the user equipment, network resources are wasted. Summary of the invention

[0003] The embodiments of the present application provide a data processing method, related equipment and a communication system. Adopting the embodiments of the present application is beneficial to saving network resources.

[0004] In a first aspect, an embodiment of the present application provides a data processing method. The method can be applied to a user plane function (UPF) entity, and can also be applied to a relay in a MoQ protocol. The relay in the MoQ protocol can be deployed in a UPF entity or independently.

[0005] The UPF entity obtains a data stream sent by an application server, the data stream including a first data set and dependency information of the first data set; the dependency information of the first data set is used to determine the data set on which the first data set depends; the UPF entity processes the first data set based on the data set on which the first data set depends.

[0006] The UPF entity processes the first data set based on the transmission result of the data set on which the first data set depends. The transmission result of the data set on which the first data set depends includes whether the data set on which the first data set depends is successfully sent to the user equipment.

[0007] The dependency information of the first data set is obtained through the UPF entity, and the first data set is scheduled using the data set on which the first data set depends, which is determined based on the dependency information of the first data set. Scheduling the data set in this way is conducive to saving network resources.

[0008] In combination with the first aspect, in a possible implementation manner, the UPF entity processes the first data set based on the data set on which the first data set depends, including:

[0009] The UPF entity determines that the first data set depends on the second data set based on the sequence number or identifier of the second data set and the dependency information of the first data set; the second data set is a data set that has not been successfully transmitted by the wireless access network RAN ​​device; based on the determination result that the first data set depends on the second data set, the UPF entity does not transmit the first data set to the RAN device (that is, the UPF discards the first data set), or discards the first data set; if the first data set does not depend on the second data set, the first data set is sent to the RAN device.

[0010] It should be understood that the data set that is not successfully transmitted by the RAN device refers to a data set that is not successfully transmitted by the RAN device to the user equipment, or a data set for which transmission resources cannot be successfully allocated to the RAN device.

[0011] Since the second data set is a data set that the RAN device has not successfully transmitted, when the first data set depends on the second data set, there is no need to transmit the first data set to the user device. Therefore, the UPF entity does not need to send the first data set to the RAN device or discard the first data set, so that the RAN device does not need to transmit the first data set to the user device, thereby saving network resources.

[0012] In combination with the first aspect, in a possible implementation manner, the dependency information of the first data set includes a serial number or an identifier of a data set on which the first data set depends, and the UPF entity determines that the first data set depends on the second data set based on the serial number or the identifier of the second data set and the dependency information of the first data set, including:

[0013] If the serial number or identifier of the data set on which the first data set depends includes the serial number or identifier of the second data set, the UPF entity determines that the first data set depends on the second data set; if the serial number or identifier of the data set on which the first data set depends does not include the serial number or identifier of the second data set, the UPF entity determines that the first data set does not depend on the second data set.

[0014] The UPF entity obtains the serial number or identifier of the data set on which the first data set depends, and determines the data set on which the first data set depends, thereby being able to accurately determine that the first data set depends on the second data set.

[0015] In combination with the first aspect, in a possible implementation manner, the dependency information of the first data set includes a priority of the first data set, and the UPF entity determines that the first data set depends on the second data set based on the sequence number or identifier of the second data set and the dependency information of the first data set, including:

[0016] The UPF entity determines the serial number or identifier of the data set on which the first data set depends based on the priority of the first data set and the dependency relationship between the priorities; if the serial number or identifier of the data set on which the first data set depends includes the serial number or identifier of the second data set, the UPF entity determines that the first data set depends on the second data set; if the serial number or identifier of the data set on which the first data set depends does not include the serial number or identifier of the second data set, the UPF entity determines that the first data set does not depend on the second data set.

[0017] The dependency relationship of each priority refers to the dependency relationship between data sets of different priorities within a group of picture (GOP), for example, a low priority data set depends on a high priority data set, and another example is a first priority data set depends on a second priority data set and a third priority data set.

[0018] The priority of the first data set is obtained through the UPF entity, and the sequence number or identifier of the data set on which the first data set depends is determined based on the priority of the first data set and the dependency relationship of each priority, so that it is possible to accurately determine whether the first data set depends on the second data set. Since the dependency information of the first data set only includes the priority of the first data set, the amount of data that should be sent by the server can be reduced, thereby further reducing network resources.

[0019] In combination with the first aspect, in a possible implementation manner, the dependency information of the first data set includes an identifier of a data stream on which the data stream to which the first data set belongs depends; the UPF entity determines that the first data set depends on the second data set based on the sequence number or identifier of the second data set and the dependency information of the first data set, including:

[0020] The UPF entity determines, based on the data stream identifier to which the data stream to which the first data stream belongs depends, the sequence number or identifier of the data set on which the first data set depends, where the data set on which the first data set depends includes a data set belonging to the data stream to which the data stream to which the first data set belongs depends;

[0021] If the serial number or identifier of the data set on which the first data set depends includes the serial number or identifier of the second data set, the UPF entity determines that the first data set depends on the second data set; if the serial number or identifier of the data set on which the first data set depends does not include the serial number or identifier of the second data set, the UPF entity determines that the first data set does not depend on the second data set.

[0022] The identifier of the data stream to which the data stream to which the first data set belongs depends is obtained through the UPF entity, and the serial number or identifier of the data set to which the first data set depends is determined based on the identifier of the data stream to which the data stream to which the first data set belongs depends, so that it is possible to accurately determine whether the first data set depends on the second data set. Since the dependency information of the first data set only includes the identifier of the data stream to which the data stream to which the first data set belongs depends, the amount of data that should be sent by the server can be reduced, thereby further reducing network resources.

[0023] In combination with the first aspect, in a possible implementation manner, the dependency information of the first data set includes a layer identifier of a data set on which the first data set depends; the UPF entity determines that the first data set depends on the second data set based on the sequence number or identifier of the second data set and the dependency information of the first data set, including:

[0024] The UPF entity determines the sequence number or identifier of the data set on which the first data set depends based on the layer identifier of the data set on which the first data set depends; the layer identifier of the data set on which the first data set depends includes an enhancement layer or a base layer;

[0025] If the serial number or identifier of the data set on which the first data set depends includes the serial number or identifier of the second data set, the UPF entity determines that the first data set depends on the second data set; if the serial number or identifier of the data set on which the first data set depends does not include the serial number or identifier of the second data set, the UPF entity determines that the first data set does not depend on the second data set.

[0026] The layer identifier of the data set on which the first data set depends is obtained through the UPF entity, and the serial number or identifier of the data set on which the first data set depends is determined based on the layer identifier of the data set on which the first data set depends, so that it can be accurately determined that the first data set depends on the second data set. Since the dependency information of the first data set only includes the layer identifier of the data set on which the first data set depends, the amount of data that should be sent by the server can be reduced, thereby further reducing network resources.

[0027] In combination with the first aspect, in a possible implementation manner, the method of this embodiment further includes:

[0028] The UPF entity obtains dependency information of the first data set and the first data set from the data stream;

[0029] Before or after the UPF entity obtains the dependency information of the first data set and the first data set from the data stream, the method of this embodiment further includes:

[0030] The UPF entity obtains the sequence number or identifier of the second data set from the RAN device.

[0031] After obtaining the dependency information of the first data set and the first data set from the data stream, the UPF entity obtains the serial number or identifier of the second data set from the RAN device. That is, before obtaining the serial number or identifier of the second data set from the RAN device, the UPF entity has already obtained the dependency information of the first data set and the first data set from the data stream. In this way, the UPF entity can directly determine that the first data set depends on the second data set when obtaining the serial number or identifier of the second data set from the RAN device, thereby improving the efficiency of data processing.

[0032] Before obtaining the dependency information of the first data set and the first data set from the data stream, the UPF entity obtains the serial number or identifier of the second data set from the RAN device. That is to say, the UPF entity will obtain the dependency information of the first data set and the first data set from the data stream when it obtains the serial number or identifier of the second data set from the RAN device. It does not identify each data stream. This can reduce the identification workload of the UPF entity and save identification resources.

[0033] In combination with the first aspect, in a possible implementation manner, the method of this embodiment further includes:

[0034] The UPF entity receives first indication information from a session management function (SMF) entity, where the first indication information is used to instruct the UPF entity to obtain dependency information of a first data set from a data stream, and schedule the first data set based on the dependency information of the first data set;

[0035] The first indication information is generated by the SMF entity based on the dependency processing indication information from the application server, where the dependency processing indication information is used to indicate that the target business can perform dependency processing, and the first data set is associated with the target business.

[0036] In combination with the first aspect, in a possible implementation manner, the method of this embodiment further includes:

[0037] The UPF entity receives second indication information from the SMF entity, where the second indication information is used to instruct the UPF entity to obtain dependency information of the first data set from the data flow and send the dependency information of the first data set to the RAN device;

[0038] The UPF entity processes the first data set based on the data set on which the first data set depends, including: the UPF entity sends the dependency information of the first data set and the first data set to the RAN device, so that the RAN device schedules the first data set based on the dependency information of the first data set.

[0039] In combination with the first aspect, in a possible implementation, the data stream is transmitted via a media over quick user datagram protocol internet connections (MoQ) protocol, and the dependency information of the first data set is carried in metadata of the MoQ protocol.

[0040] In combination with the first aspect, in one possible implementation, the data stream is transmitted via a Quick User Datagram Protocol internet connections (QUIC) protocol, and the dependency information of the first data set is carried in a data packet of the QUIC protocol.

[0041] In combination with the first aspect, in one possible implementation, the data stream is transmitted via a real-time transport protocol (RTP) or a secure real-time transport protocol (SRTP), and the dependency information of the first data set is carried in a data packet header of the RTP or SRTP protocol.

[0042] In a second aspect, an embodiment of the present application provides a data processing method, which is applied to a RAN device.

[0043] The RAN device receives a first data set and dependency information of the first data set sent by a UPF entity; the dependency information of the first data set is used to determine a data set on which the first data set depends; and the RAN device schedules the first data set based on the data set on which the first data set depends.

[0044] Obtaining dependency information of the first data set through the RAN device, and scheduling the first data set using a data set on which the first data set depends, determined based on the dependency information of the first data set.

The method is applied to a UPF entity, where the UPF entity is Figure 1 The UPF entity in the 5G system or the relay node in the MoQ protocol is shown in the figure. The relay node in the MoQ protocol can be deployed in the UPF entity or independently. Figure 2 As shown, the method includes:

[0118] S201. A UPF entity obtains a data stream sent by an application entity. The data stream includes a first data set and dependency information of the first data set. The dependency information of the first data set is used to determine a data set on which the first data set depends.

[0119] In one example, the data stream may include at least one of a video stream, an audio stream, a tactile stream, etc. When the data stream includes a video stream, the first data set may be a frame in the video stream, such as an I frame, a P frame, etc., and the first data set may also be a base layer or an enhanced layer of the video stream; when the data stream includes an audio stream, the first data set is a data set of the audio stream; when the data stream includes a tactile stream, the first data set is a data set of the tactile stream.

[0120] The data set on which the first data set depends refers to the data set that the user equipment needs to rely on when processing the first data set. For example, the layer identifier of the first data set is an enhanced layer. At this time, the processing of the first data set needs to rely on the data set whose layer identifier is the basic layer. The data set on which the first data set depends includes the data set whose layer identifier is the basic layer.

[0121] In one example, the dependency information of the first data set includes the sequence number or identifier of the data set on which the first data set depends, the priority of the first data set, the identifier of the data stream on which the data stream to which the first data set belongs depends, or the layer identifier of the data set on which the first data set depends.

[0122] S202. The UPF entity obtains dependency information of the first data set and the first data set from the data stream.

[0123] In a possible implementation, the data stream is transmitted through the MoQ protocol, and the dependency information of the first data set is carried in the metadata of the MoQ protocol. In other words, the data stream is transmitted through the MoQ message, and the dependency information of the first data set is carried in the metadata of the MoQ message header. The UPF entity obtains the dependency information of the first data set and the first data set from the data stream specifically refers to the UPF entity obtaining the dependency information of the first data set and the first data set from the MoQ message.

[0124] In one possible implementation, the data stream is transmitted through the QUIC protocol, and the dependency information of the first data set is carried in the metadata of the QUIC protocol. In other words, the data stream is transmitted through the QUIC message, and the dependency information of the first data set is carried in the data packet of the QUIC message. The UPF entity obtains the dependency information of the first data set and the first data set from the data stream specifically refers to the UPF entity obtaining the dependency information of the first data set and the first data set from the QUIC message.

[0125] In a possible implementation manner, the data stream is transmitted via RTP or SRTP, and the dependency information of the first data set is carried in a data packet header of RTP or SRTP.

[0126] S203. The UPF entity processes the first data set based on the data sets on which the first data set depends.

[0127] In a possible implementation, the method of this embodiment further includes:

[0128] The UPF entity receives the first indication information from the SMF entity, and the first indication information is used to instruct the UPF entity to obtain the dependency information of the first data set from the data stream, and schedule the first data set based on the dependency information of the first data set; the first indication information is generated by the SMF entity based on the dependency processing indication information from the application server, and the dependency processing indication information is used to indicate that the target service can perform dependency processing, and the first data set is associated with the target service. For example, the target service is a video service, the data stream is a video stream, and the first data set is a video frame in the video stream.

[0129] It should be understood that, for different services, some services can perform dependency processing, such as video services, while others cannot perform dependency processing. For services that can perform dependency processing, the application server sends dependency processing indication information to the PCF entity, and the PCF entity generates a PCC rule including the dependency processing indication information, and sends the PCC rule to the SMF entity. The SMF entity generates first indication information according to the dependency processing indication information in the PCC rule.

[0130] After receiving the first indication information, the UPF entity obtains the first data set and the dependency information of the first data set from the data stream based on the first indication information when receiving the data stream from the application server; the UPF entity determines the sequence number or identifier of the data set on which the first data set depends based on the dependency information of the first data set, and the UPF entity schedules the first data set based on the dependency information of the first data set. Specifically, the UPF entity determines whether the first data set depends on the second data set based on the sequence number or identifier of the second data set and the dependency information of the first data set. Among them, the second data set is a data set that the RAN device has not successfully transmitted. If it is determined that the first data set depends on the second data set, the UPF entity does not send the first data set to the RAN device (it can also be said that the first data set is discarded, which will not be described in detail in subsequent embodiments); if it is determined that the first data set does not depend on the second data set, the UPF entity sends the first data set to the RAN device. When it is determined that the first data set depends on the second data set, the UPF entity discards the first data set, which can reduce the storage overhead of the UPF entity.

[0131] In one example, if the serial number or identifier of the data set on which the first data set depends includes the serial number or identifier of the second data set, the UPF entity determines that the first data set depends on the second data set; if the serial number or identifier of the data set on which the first data set depends does not include the serial number or identifier of the second data set, the UPF entity determines that the first data set does not depend on the second data set.

[0132] In one possible implementation, the dependency information of the first data set includes the sequence number or identifier of the data set on which the first data set depends, the priority of the first data set, the identifier of the data stream on which the data stream to which the first data set belongs depends, or the layer identifier of the data set on which the first data set depends.

[0133] When the dependency information of the first data set includes the priority of the first data set, the UPF entity determines the sequence number or identifier of the data set on which the first data set depends based on the priority of the first data set and the dependency relationship of each priority level. The dependency relationship of each priority level refers to the dependency relationship between data sets of different priorities within a GOP. For example, a low-priority data set depends on a high-priority data set, and another example is a first-priority data set depends on a second-priority data set and a third-priority data set. Optionally, the dependency relationship of each priority level is pre-configured in the UPF entity, or is sent to the UPF entity by the application server when or before sending the data set belonging to a new GOP to the UPF entity.

[0134] When the dependency information of the first data set includes the identifier of the data stream on which the data stream to which the first data set belongs depends, the UPF entity determines the data stream on which the data stream to which the first data set belongs depends based on the identifier of the data stream on which the data stream to which the first data set belongs depends, determines the data set belonging to the data stream on which the data stream to which the first data set belongs depends as the data set on which the first data set depends, and then determines the sequence number or identifier of the data set on which the first data set depends.

[0135] When the dependency information of the first data set includes the layer identifier of the data set on which the first data set depends, and the layer identifier of the data set on which the first data set depends includes an enhanced layer or a base layer, the UPF entity determines the data set on which the first data set depends based on the layer identifier of the data set on which the first data set depends, and then determines the sequence number or identifier of the data set on which the first data set depends. For example, if the layer identifier of the data set on which the first data set depends is the base layer, the UPF entity determines the data set on which the first data set depends by identifying the layer as the data set of the base layer; for another example, if the layer identifier of the data set on which the first data set depends is the first enhanced layer, the UPF entity determines the data set on which the first data set depends by identifying the layer as the data set of the first enhanced layer; for another example, if the layer identifier of the data set on which the first data set depends is the second enhanced layer, the UPF entity determines the data set on which the first data set depends by identifying the layer as the data set of the second enhanced layer.

[0136] Optionally, the dependency processing indication information includes fifth indication information, and the fifth indication information is used to indicate that packet loss is allowed. The SMF entity sends the fifth indication information to the UPF entity.

[0137] In a possible implementation, before or after the UPF entity obtains the dependency information of the first data set and the first data set from the data stream, the method of this embodiment further includes:

[0138] The UPF entity obtains information of the second data set from the RAN device, such as a sequence number, an identifier or other information, which is not limited here.

[0139] After obtaining the dependency information of the first data set and the first data set from the data stream, the UPF entity obtains the serial number or identifier of the second data set from the RAN device. That is, before obtaining the serial number or identifier of the second data set from the RAN device, the UPF entity has already obtained the dependency information of the first data set and the first data set from the data stream. In this way, the UPF entity can directly determine whether the first data set depends on the second data set when obtaining the serial number or identifier of the second data set from the RAN device, thereby improving the efficiency of data processing.

[0140] Before obtaining the dependency information of the first data set and the first data set from the data stream, the UPF entity obtains the serial number or identifier of the second data set from the RAN device. That is to say, the UPF entity will obtain the dependency information of the first data set and the first data set from the data stream when it obtains the serial number or identifier of the second data set from the RAN device. It does not identify each data stream. This can reduce the identification workload of the UPF entity and save identification resources.

[0141] In a possible implementation, the method of this embodiment further includes:

[0142] The UPF entity receives second indication information from the SMF entity, and the second indication information is used to instruct the UPF entity to obtain dependency information of the first data set from the data flow and send the dependency information of the first data set to the RAN device; the UPF entity processes the first data set based on the data set on which the first data set depends, including: the UPF entity sends the dependency information of the first data set and the first data set to the RAN device, so that the RAN device schedules the first data set based on the dependency information of the first data set.

[0143] Specifically, after receiving the second indication information, the UPF entity obtains the dependency information of the first data set from the data stream based on the second indication information when receiving the data stream from the application server, obtains the first data set, sends the dependency information of the first data set to the RAN device, and sends the first data set to the RAN device at the same time. In an example, the UPF entity sends a general packet radio service (GPRS) user plane tunneling protocol (GPRS tunnelling protocol for the user plane) GTP-U message to the RAN device. The GTP-U message includes the dependency information of the first data set and the first data set, and the dependency information of the first data set is encapsulated in the message of the GTP-U message.

[0144] It can be seen that in the solution of the present application, the UPF entity obtains the dependency information of the first data set, and schedules the first data set using the data set that the first data set depends on based on the dependency information of the first data set. When the second data set that the first data set depends on cannot be successfully transmitted to the user equipment, the first data set is not sent to the RAN device, so that the RAN device does not need to transmit the first data set to the user equipment, saving network resources. After receiving the sequence number or identifier of the data set that was not successfully transmitted sent by the RAN device, the received data stream is identified to obtain the first data set and the dependency information of the first data set. There is no need to identify all received data streams, which can reduce the complexity of identification and identification resources.

[0146] The method includes:

[0147] S301. A RAN device receives a first data set and dependency information of the first data set sent by a UPF entity; the dependency information of the first data set is used to determine a data set on which the first data set depends.

[0148] In one example, the UPF entity sends a GTP-U message to the RAN device. The GTP-U message includes dependency information of the first data set and the first data set, and the dependency information of the first data set is encapsulated in the message of the GTP-U message. The RAN device obtains the first data set and the dependency information of the first data set from the GTP-U message.

[0149] It should be noted here that the specific description of the first data set and the dependency information of the first data set can be found in the relevant description of S201, which will not be described again here.

[0150] S302: The RAN device schedules the first data set based on the data set on which the first data set depends.

[0151] It should be noted here that the RAN device scheduling the first data set based on the data set on which the first data set depends specifically means that the RAN device schedules the first data set based on the transmission result of the data set on which the first data set depends.

[0152] The RAN device determines the data set on which the first data set depends based on the dependency information of the first data set, wherein the dependency information of the first data set includes the sequence number or identifier of the data set on which the first data set depends, the priority of the first data set, the identifier of the data flow on which the data flow to which the first data set belongs depends, or the layer identifier of the data set on which the first data set depends.

[0153] When the dependency information of the first data set includes the priority of the first data set, the RAN device determines the data set or identifier on which the first data set depends based on the priority of the first data set and the dependency relationship of each priority level. The dependency relationship of each priority level refers to the dependency relationship between data sets of different priorities within a GOP. For example, a low-priority data set depends on a high-priority data set, and another example is that a data set of the first priority level depends on a data set of the second priority level and a data set of the third priority level. Optionally, the dependency relationship of each priority level is pre-configured in the RAN device, or is sent to the RAN device by the UPF entity when or before the application server sends the data set belonging to the new GOP to the UPF entity.

[0154] When the dependency information of the first data set includes the identifier of the data stream on which the data stream to which the first data set belongs depends, the RAN device determines the data stream on which the data stream to which the first data set belongs depends based on the identifier of the data stream on which the data stream to which the first data set belongs depends, and the RAN device determines the data set belonging to the data stream on which the data stream to which the first data set belongs depends as the data set on which the first data set depends, and then determines the sequence number or identifier of the data set on which the first data set depends.

[0155] When the dependency information of the first data set includes the layer identifier of the data set on which the first data set depends, and the layer identifier of the data set on which the first data set depends includes an enhanced layer or a base layer, the RAN device determines the data set on which the first data set depends based on the layer identifier of the data set on which the first data set depends, and further determines the sequence number or identifier of the data set on which the first data set depends. For example, if the layer identifier of the data set on which the first data set depends is the base layer, the RAN device determines the data set on which the first data set depends by using the data set with the layer identifier as the base layer; for another example, if the layer identifier of the data set on which the first data set depends is the first enhanced layer, the RAN device determines the data set on which the first data set depends by using the data set with the layer identifier as the first enhanced layer; for another example, if the layer identifier of the data set on which the first data set depends is the second enhanced layer, the RAN device determines the data set on which the first data set depends by using the data set with the layer identifier as the data set with the second enhanced layer.

[0156] The RAN device schedules the first data set based on the data set on which the first data set depends, specifically including: the RAN device determines whether the first data set depends on the second data set based on the dependency information of the first data set. The second data set is a data set that the RAN device has not successfully transmitted. If the sequence number or identifier of the data set on which the first data set depends includes the sequence number or identifier of the second data set, the RAN device determines that the first data set depends on the second data set; if the sequence number or identifier of the data set on which the first data set depends does not include the sequence number or identifier of the second data set, the RAN device determines that the first data set does not depend on the second data set.

[0157] If it is determined that the first data set depends on the second data set, the RAN device does not send the first data set to the user equipment or discards the first data set; if it is determined that the first data set does not depend on the second data set, the RAN device sends the first data set to the user equipment and records the first data and whether it is successfully sent to the user equipment. When the first data set cannot be successfully transmitted to the user equipment, the RAN device sends the sequence number or identifier of the first data set to the UPF entity. When it is determined that the first data set depends on the second data set, the RAN device discards the first data set, which can reduce the storage overhead of the UPF entity.

[0158] Optionally, the RAN device receives fourth indication information sent from the SMF entity, where the fourth indication information is used to instruct the RAN device to schedule the first data set based on dependency information of the first data set.

[0159] In a possible implementation, the method of the embodiment of the present application further includes:

[0160] The RAN device receives the third indication information sent by the SMF entity, where the third indication information is used to instruct the RAN device to feed back to the UPF entity the sequence number or identifier of the data set that was not successfully transmitted.

[0161] Optionally, the dependency processing indication information includes fifth indication information, and the fifth indication information is used to indicate that packet loss is allowed. The SMF entity sends the fifth indication information to the RAN device.

[0162] It can be seen that in the scheme of the present application, the RAN device obtains the dependency information of the first data set, and schedules the first data set using the data set on which the first data set depends, determined based on the dependency information of the first data set; when the second data set on which the first data set depends cannot be successfully transmitted to the user device, the RAN device does not transmit the first data set to the user device, thereby saving network resources, discarding the first data set, and reducing storage overhead.

[0163] It should be understood that in the solution of the present application, different data sets can be distinguished based on the sequence number, identification or other information of the data set, which is not limited here.

[0164] See also Figure 4 , Figure 4 An interactive flow chart of a data processing method provided in an embodiment of the present application. The method is applied to Figure 1 The system shown. Figure 4 As shown, the method includes:

[0165] S401. The application server sends dependency processing instruction information to the PCF entity.

[0166] Specifically, an application function (AF) entity in the application server sends dependency processing indication information to the PCF entity.

[0167] The dependency handling indication information is used to indicate that the target service can perform dependency handling.

[0168] Optionally, the dependency processing indication information includes fifth indication information, where the fifth indication information is used to indicate that autonomous packet loss is allowed, such as indicating that the RAN device is allowed to autonomously lose packets.

[0169] It should be understood that S401 is optional.

[0170] S402. The PCF entity sends the PCC rules to the SMF entity.

[0171] Specifically, when the PCF entity receives the dependency processing indication information, it generates a PCC rule and sends the PCC rule to the SMF entity, wherein the PCC rule includes the dependency processing indication information.

[0172] S403: The SMF entity binds the PCC rule to a new QoS flow.

[0173] It should be understood that S403 is optional.

[0174] S404. The SMF entity sends a second indication message to the UPF entity.

[0175] The second indication information is used to instruct the UPF entity to obtain the dependency information of the first data set from the data flow and send the dependency information of the first data set to the RAN device. Optionally, the second indication information is also used to instruct the UPF entity to identify the dependency information and encapsulate the dependency information into the message header of the GTP-U message. The second indication information includes PCCrule.

[0176] Optionally, the SMF entity sends fourth indication information to the RAN device, where the fourth indication information is used to instruct the RAN device to schedule the first data set based on dependency information of the first data set.

[0177] S405. The application server sends data stream to the UPF entity.

[0178] The data stream includes a first data set and dependency information of the first data set. The dependency information of the first data set is used to determine a data set on which the first data set depends. The first data set is associated with a target service.

[0179] Optionally, the dependency information of the first data set includes the sequence number or identifier of the data set on which the first data set depends, the priority of the first data set, the identifier of the data stream on which the data stream to which the first data set belongs depends, or the layer identifier of the data set on which the first data set depends.

[0180] Optionally, the priority of the first data set is used to reflect the importance of the first data set. The higher the importance of the first data set, the higher the priority of the first data set. In an example, the priority of the first data set can be determined by the sending order of the first data set. The earlier the sending order, the higher the priority. The layer identifier of the first data set includes an enhancement layer or a base layer.

[0181] S406. The UPF entity obtains dependency information of the first data set and the first data set from the data stream.

[0182] It should be pointed out here that the specific process of the UPF entity obtaining the dependency information of the first data set and the first data set from the data stream can be found in the relevant description of S202 and will not be described again here.

[0183] S407. The UPF entity sends the dependency information of the first data set and the first data set to the RAN device.

[0184] Specifically, the UPF entity obtains the dependency information of the first data set and the first data set from the data stream, and sends the dependency information of the first data set and the first data set to the RAN device. In one example, the UPF entity sends a GTP-U message to the RAN device. The GTP-U message includes the dependency information of the first data set and the first data set, and the dependency information of the first data set is encapsulated in the message header of the GTP-U message.

[0185] S408. The RAN device schedules the first data set based on the data set on which the first data set depends.

[0186] Specifically, the RAN device schedules the first data set based on the dependency information of the first data set, wherein the dependency information of the first data set includes a sequence number or identifier of a data set on which the first data set depends, a priority of the first data set, an identifier of a data flow on which a data flow to which the first data set belongs depends, or a layer identifier of a data set on which the first data set depends.

[0187] When the dependency information of the first data set includes the priority of the first data set, the RAN device determines the sequence number or identifier of the data set on which the first data set depends based on the priority of the first data set and the dependency relationship of each priority level. The dependency relationship of each priority level refers to the dependency relationship between data sets of different priorities within a GOP. For example, a low-priority data set depends on a high-priority data set, and another example is that a data set of the first priority level depends on a data set of the second priority level and a data set of the third priority level. Optionally, the dependency relationship of each priority level is pre-configured in the RAN device, or is sent to the RAN device by the UPF entity when or before the application server sends the data set belonging to the new GOP to the UPF entity.

[0188] When the dependency information of the first data set includes the identifier of the data stream on which the data stream to which the first data set belongs depends, the RAN device determines the data stream on which the data stream to which the first data set belongs depends based on the identifier of the data stream on which the data stream to which the first data set belongs depends, and the RAN device determines the data set belonging to the data stream on which the data stream to which the first data set belongs depends as the data set on which the first data set depends, and then determines the sequence number or identifier of the data set on which the first data set depends.

[0189] When the dependency information of the first data set includes the layer identifier of the data set on which the first data set depends, and the layer identifier of the data set on which the first data set depends includes an enhanced layer or a base layer, the RAN device determines the data set on which the first data set depends based on the layer identifier of the data set on which the first data set depends, and further determines the sequence number or identifier of the data set on which the first data set depends. For example, if the layer identifier of the data set on which the first data set depends is the base layer, the RAN device determines the data set on which the first data set depends by using the data set with the layer identifier as the base layer; for another example, if the layer identifier of the data set on which the first data set depends is the first enhanced layer, the RAN device determines the data set on which the first data set depends by using the data set with the layer identifier as the first enhanced layer; for another example, if the layer identifier of the data set on which the first data set depends is the second enhanced layer, the RAN device determines the data set on which the first data set depends by using the data set with the layer identifier as the data set with the second enhanced layer.

[0190] The RAN device schedules the first data set based on the data set on which the first data set depends, specifically including: the RAN device determines whether the first data set depends on the second data set based on the dependency information of the first data set. The second data set is a data set that the RAN device has not successfully transmitted. If the sequence number or identifier of the data set on which the first data set depends includes the sequence number or identifier of the second data set, the RAN device determines that the first data set depends on the second data set; if the sequence number or identifier of the data set on which the first data set depends does not include the sequence number or identifier of the second data set, the RAN device determines that the first data set does not depend on the second data set.

[0191] If it is determined that the first data set depends on the second data set, the RAN device does not send the first data set to the user equipment or discards the first data set; if it is determined that the first data set does not depend on the second data set, the RAN device sends the first data set to the user equipment and records the first data and whether it is successfully sent to the user equipment. When the first data set cannot be successfully transmitted to the user equipment, the RAN device sends the sequence number or identifier of the first data set to the UPF entity. When it is determined that the first data set depends on the second data set, the RAN device discards the first data set, which can reduce the storage overhead of the UPF entity.

[0192] It should be understood that after the RAN device receives the dependency information of the first data set, the RAN device caches the priority or layer identifier of the first data set so that the RAN device can determine whether a subsequently received data set depends on the first data set. After a preset time, the RAN device deletes the priority or layer identifier of the first data set to save storage resources.

[0207] S506. The application server sends data stream to the UPF entity.

[0208] The data stream includes a first data set and dependency information of the first data set. The dependency information of the first data set is used to determine a data set on which the first data set depends. The first data set is associated with a target service.

[0209] Optionally, the dependency information of the first data set includes the sequence number or identifier of the data set on which the first data set depends, the priority of the first data set, the identifier of the data stream on which the data stream to which the first data set belongs depends, or the layer identifier of the data set on which the first data set depends.

[0210] Optionally, the priority of the first data set is used to reflect the importance of the first data set.

In an example, the priority of the first data set can be determined by the sending order of the first data set. The earlier the sending order, the higher the priority. The layer identifier of the first data set includes an enhancement layer or a base layer.

[0214] The second data set is a data set that the RAN device has not successfully transmitted to the user equipment.

[0215] It should be pointed out here that S407 can be executed after S408, that is, after receiving the serial number or identifier of the second data set, the UPF entity obtains the dependency information of the first data set from the data stream, or the UPF entity parses the dependency information of the first data set in the received data stream after receiving the serial number or identifier of the second data set, instead of parsing the dependency information for each data stream, which can reduce the workload of the UPF entity.

[0216] S509. The UPF entity schedules the first data set based on the data sets on which the first data set depends.

[0217] When receiving a data stream from an application server, a first data set and dependency information of the first data set are obtained from the data stream based on the first indication information; the UPF entity schedules the first data set based on the dependency information of the first data set. Specifically, the UPF entity determines whether the first data set depends on the second data set based on the sequence number or identifier of the second data set and the dependency information of the first data set. The second data set is a data set that the RAN device has not successfully transmitted. If it is determined that the first data set depends on the second data set, the UPF entity does not send the first data set to the RAN device or discards the first data set; if it is determined that the first data set does not depend on the second data set, the UPF entity sends the first data set to the RAN device. When it is determined that the first data set depends on the second data set, the UPF entity discards the first data set, which can reduce the storage overhead of the UPF entity.

[0218] In one example, if the serial number or identifier of the data set on which the first data set depends includes the serial number or identifier of the second data set, the UPF entity determines that the first data set depends on the second data set; if the serial number or identifier of the data set on which the first data set depends does not include the serial number or identifier of the second data set, the UPF entity determines that the first data set does not depend on the second data set.

[0219] In one possible implementation, the dependency information of the first data set includes the sequence number or identifier of the data set on which the first data set depends, the priority of the first data set, the identifier of the data stream on which the data stream to which the first data set belongs depends, or the layer identifier of the data set on which the first data set depends.

[0220] When the dependency information of the first data set includes the priority of the first data set, the UPF entity determines the sequence number or identifier of the data set on which the first data set depends based on the priority of the first data set and the dependency relationship of each priority level. The dependency relationship of each priority level refers to the dependency relationship between data sets of different priorities within a GOP. For example, a low-priority data set depends on a high-priority data set, and another example is a first-priority data set depends on a second-priority data set and a third-priority data set. Optionally, the dependency relationship of each priority level is pre-configured in the UPF entity, or is sent to the UPF entity by the application server when or before sending the data set belonging to a new GOP to the UPF entity.

[0221] When the dependency information of the first data set includes the identifier of the data stream on which the data stream to which the first data set belongs depends, the UPF entity determines the data stream on which the data stream to which the first data set belongs depends based on the identifier of the data stream on which the data stream to which the first data set belongs depends, determines the data set belonging to the data stream on which the data stream to which the first data set belongs depends as the data set on which the first data set depends, and then determines the sequence number or identifier of the data set on which the first data set depends.

[0222] When the dependency information of the first data set includes the layer identifier of the data set on which the first data set depends, and the layer identifier of the data set on which the first data set depends includes an enhanced layer or a base layer, the UPF entity determines the data set on which the first data set depends based on the layer identifier of the data set on which the first data set depends, and then determines the sequence number or identifier of the data set on which the first data set depends. For example, if the layer identifier of the data set on which the first data set depends is the base layer, the UPF entity determines the data set on which the first data set depends by identifying the layer as the data set of the base layer; for another example, if the layer identifier of the data set on which the first data set depends is the first enhanced layer, the UPF entity determines the data set on which the first data set depends by identifying the layer as the data set of the first enhanced layer; for another example, if the layer identifier of the data set on which the first data set depends is the second enhanced layer, the UPF entity determines the data set on which the first data set depends by identifying the layer as the data set of the second enhanced layer.

[0223] It should be understood that after the UPF entity receives the dependency information of the first data set, the UPF entity caches the priority or layer identifier of the first data set so that the UPF entity can determine whether the subsequently received data set depends on the first data set. After a preset time, the UPF entity deletes the priority or layer identifier of the first data set to save storage resources.
