[0073] There is a key performance indicator (KPI) in XRM: QoS Handling when Traffic Characteristics Change Dynamically. This mainly includes two scenarios:

[0074] 1) Periodic or aperiodic burst data packet;

[0075] 2) When watching a video, there is a requirement for a second to open, i.e. to download large data packets of video and audio data from a service server within 1s.

[0076] The feature of scenario 1) is that the size of burst is variable, for example, in some complex videos, the burst is large (more changes need to be presented), and in some simple videos, the size of burst is small.

[0077] Scenario 2) has a requirement for a large burst size at the beginning, i.e. high QoS requirement, but subsequently, as the video plays into a flat state, the bite rate of the entire data stream becomes relatively low. However, the bandwidth and delay requirement under the normal state is usually negotiated by the service and the network.

[0078] In the related art, a mechanism of a protocol data unit (PDU) set (also referred to as a PDU set) is designed, wherein PDU set information includes a value called length or size, which is carried in a packet header, but the value is measured in bytes to measure the size of a packet. A radio access network (RAN) needs to identify the variable bytes to schedule resources to meet the bandwidth and delay requirements in a normal state. Since the XRM service has high QoS requirements, the existing technical solutions cannot provide flexible QoS guarantee for variable packet sizes, and cannot provide QoS guarantee for XRM services.

[0079] Based on this, in various embodiments of the present application, the EES sends first information, the first information including one or more of the following: an N6 delay measurement request, information of an EAS or an EAS list, a DNAI or a DNAI list, an N6 delay requirement; the first network function receives third information, the third information being used to indicate the MDBV and / or duration of the first data flow; the second network function receives fourth information sent by the first network function, the fourth information being used to indicate that the second network function generates a QoS rule for a different DBV of the first data flow; the third network function receives sixth information sent by the second network function, the sixth information representing data processing indication information of the first data flow. As can be seen, in the embodiments of the present application, the EES can indicate the network to measure the delay of the N6 interface, and / or the N6 delay requirement and / or the EAS and / or the DNAI used to provide services, thereby providing QoS guarantee for services or data flows with high QoS requirements; the first network function can provide QoS guarantee for the first data flow according to the third information, the second network function can provide QoS guarantee for the first data flow according to the fourth information, and the third network function can provide QoS guarantee for the first data flow according to the sixth information, thereby improving the QoS of the first data flow.

[0080] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

The EAS can be a service platform of the XR service and / or the XRM service, and the EES can be a platform carrying the XR service and / or the XRM service. The EAS list can contain information of one or more EASs, and the information of the EAS can include one or more of the following: EAS identifier, EAS type, EAS address information, fully qualified domain name (FQDN) of the EAS, and Internet Protocol (IP) address of the EAS.

[0093] Here, receiving the second information can be understood as receiving the second information sent by the network, for example, receiving the second information sent by the 5G network.

[0100] Here, the first network function can receive the third information sent directly or indirectly by the fourth network function, the fourth network function including an application function (AF, Application Function) and / or a network exposure function (NEF, Network Exposure Function). For example, the AF sends the third information to the first network function through the NEF. The first data flow includes the data flow of the XR service and / or the data flow of the XRM service. The duration can be described as the duration of seconds.

[0101] It should be noted that the MDBV represents the maximum amount of data that the 5G access network (5G-AN, 5G-Access Network) can provide services during the 5G access network packet delay budget (5G-AN PDB, 5G-AN Packet Delay Budget); it is also the maximum value of the number of data packets that the radio access network (RAN, Radio Access Network) can schedule within the allowed time; the data packet can be referred to as a packet, and the packet can be a burst packet, and the number of data packets can be referred to as the number of packets or the number of packets. The value of the MDBV represents the maximum number of packets that the RAN needs to process. Data is not always at MDBV, and is often in a changing state; as shown in FIG. 3, the amount of downlink data of the access stratum (AS, Access-Stratum) is different from the amount of downlink data of the user plane function (UPF, User Plane Function), and the amount of downlink data of the UPF is different from the amount of downlink data of the RAN.

[0102] In an embodiment, the third information comprises one or more of the following:

[0114] For example, after the PCF obtains the value of the MDBV of the first data flow, a plurality of different DBVs are designed for the first data flow. For example, the value of the MDBV is 15M bits (bit), then the PCF can determine or generate 3 DBVs according to local configuration or AF indication, the 3 DBVs being DBV1 = 5Mbit, DBV2 = 10Mbit, and DBV3 = MDBV = 15Mbit respectively; and the DBV level record is set as DBV1, DBV2, MDBV.

[0185] Here, the PCF receives the third information, parses the value of the MDBV of the first data flow from the third information, determines a plurality of different DBVs of the first data flow according to the value of the MDBV of the first data flow, and sends the fourth information to the SMF according to the plurality of different DBVs. The fourth information includes PCC rules and / or QoS rules related to the first data flow. The fourth information includes one or more of the following:

[0186] PCC rules of each DBV of the first data flow, and / or QoS rules of each DBV of the first data flow.

[0187] For example, after the PCF obtains the value of the MDBV of the first data flow, the PCF designs multiple different DBVs for the first data flow and generates fourth information to send to the SMF. For example, the value of the MDBV is 15M bits, and the PCF can determine or generate 3 DBVs according to local configuration or AF indication, and the 3 DBVs are DBV1 = 5Mbit, DBV2 = 10Mbit, and DBV3 = MDBV = 15Mbit. The PCF sets the DBV level record as DBV1, DBV2, and MDBV. The PCF generates the PCC rule and / or the QoS rule related to the first data flow, and sends the generated QoS rule and / or the QoS rule to the SMF.

[0188] Step 3: The SMF receives the fourth information and sends fifth information to the RAN.

[0189] Here, the fifth information is used to indicate at least the QoS rule of the different DBV of the first data flow; wherein the fifth information includes one or more of the following:

[0190] the QoS rule of each DBV of the first data flow;

[0191] the multiple different DBVs of the first data flow;

[0192] the seventh information, the seventh information is used to indicate that the network device schedules resources and / or provides QoS guarantee for the first data flow according to the first identifier carried in the packet of the first data flow.

[0193] The first identifier includes a first DBV identifier and / or a second DBV identifier, the first DBV identifier indicates the value of the DBV of the first data flow, and the second DBV identifier indicates the value of the DBV within the duration of the first data flow.

[0194] For example, the SMF sends the QoS rule included in the fifth information to the RAN. The RAN is instructed that the DBV of the first data flow (generally identified by IP quintuple) has 3 values, which are DBV1 = 5Mbit, DBV2 = 10Mbit, and DBV3 = MDBV = 15Mbit. The RAN is instructed to identify the first DBV identifier and / or the second DBV identifier carried in the GTP-U header of the packet of the first data flow.

[0195] Step 4: The SMF sends sixth information to the UPF.

[0196] Here, the sixth information represents the indication information related to the data processing of the first data flow, and the sixth information can be understood as a PDR and / or a FAR. The sixth information includes one or more of the following:

[0197] the first indication, the first indication is used to instruct the UPF to identify the packet of the first data flow;

[0198] The second indication is used to instruct the UPF to count the packets or identify a third value carried in the packet header of the first data stream, the third value representing the number of packets, and different numbers of packets correspond to different values of DBV.

[0199] The third indication is used to instruct the UPF to mark different DBV identifiers for different packets, and different DBV identifiers correspond to different values of DBV.

[0200] The fourth indication is used to instruct the UPF to add a third identifier in the packets of the first data stream. The third identifier includes one or more of the following:

[0201] The QoS identifier of the duration of the first data stream;

[0202] The second DBV identifier, which indicates the value of DBV within the duration of the first data stream;

[0203] The start identifier, which indicates the first packet within the duration of the first data stream;

[0204] The second identifier, which indicates the packet within the duration of the first data stream;

[0205] The end identifier, which indicates the last packet within the duration of the first data stream.

[0206] For example, the SMF sends data processing indication information such as PDR / FAR to the UPF, instructing the UPF to identify the packets of the first data stream and count the packets. For different numbers of packets, the UPF marks different values of DBV, which are used to instruct the RAN to perform resource scheduling according to the values of DBV. Optionally, the AS can also carry a third value (for example, as shown in FIG. 7) in the packet header at the beginning of sending the packet. The UPF identifies the third value according to local configuration or policy information and maps the third value to different values of DBV. In FIG. 7, the third indication and / or the second DBV identifier can be carried in the packet header (GTP-U header) of the first data stream, and the third value can be carried in the payload of the first data stream.

[0207] Step 5: The UPF transmits downlink data to the RAN.

[0208] Step 6: The RAN dynamically schedules network resources according to the values of DBV.

[0209] Here, the RAN dynamically schedules network resources according to the values of DBV indicated by the first identifier and / or the third identifier carried in the packets of the first data stream, so as to realize the forwarding of the packets within an AN PDB time.

[0210] Application Example Two

[0211] The RAN dynamically schedules network resources to meet the QoS requirements of XR services; the difference between Application Example Two and Application Example One is that Application Example Two focuses on large data packets in the data start phase being delivered to the terminal in a short time, and the terminal includes a user equipment (UE, User Equipment). In the case of a first network function being a PCF, a second network function being an SMF, a third network function being a UPF, and a network device being a RAN, as shown in FIG. 8, the data transmission method includes:

[0212] Step 1: The AF sends third information to the PCF through the NEF.

[0213] Here, the third information indicates the value and duration of the MDBV of the first data flow, wherein the third information at least includes the value of the MDBV of the first data flow, the duration of the first data flow, and a data transmission protocol.

[0214] For example, the AF indicates the value of the MDBV and the duration for the first data flow, and sends a data transmission protocol identifier, such as a protocol description identifier. The first data flow refers to the data flow of the XR service and / or the XRM service.

[0215] Step 2: The PCF receives the third information and sends fourth information to the SMF.

[0216] Here, the PCF receives the third information, parses the value and duration of the MDBV of the first data flow from the third information, determines a plurality of different DBVs of the first data flow according to the value of the MDBV of the first data flow, and sends the fourth information to the SMF according to the plurality of different DBVs. The fourth information includes PCC rules and / or QoS rules related to the first data flow. The fourth information includes one or more of the following:

[0217] PCC rules for each DBV of the first data flow;

[0218] QoS rules for each DBV of the first data flow;

[0219] PCC rules within the duration of the first data flow;

[0220] QoS rules within the duration of the first data flow.

[0221] For example, after the PCF obtains the value of the MDBV of the first data flow, the PCF designs a plurality of different DBVs for the first data flow, and generates fourth information to the SMF to instruct the SMF to generate a QoS rule for the duration of the first data flow and to generate a QoS rule for a second data flow; the second data flow is different from the first data flow, and the second data flow can be understood as a normal data flow or a data flow with lower QoS requirements. For example, the value of the MDBV is 15M bits (bit), and then the PCF can determine or generate 3 DBVs according to the local configuration or the AF indication, and the 3 DBVs are DBV1 = 5Mbit, DBV2 = 10Mbit, and DBV3 = MDBV = 15Mbit respectively; the DBV level record is set as DBV1, DBV2, and MDBV; the PCF generates the PCC rule and / or the QoS rule related to the first data flow, and sends the generated QoS rule and / or the QoS rule to the SMF.

[0222] Step 3: The SMF receives the fourth information, and sends fifth information to the RAN.

[0223] Here, the fifth information is used at least to indicate the QoS rule of the different DBV of the first data flow; wherein the fifth information includes one or more of the following:

[0224] the QoS rule of each DBV of the first data flow;

[0225] the QoS rule within the duration of the first data flow;

[0226] the plurality of different DBVs of the first data flow;

[0227] The seventh information is used to instruct the network device to schedule resources and / or provide QoS guarantee for the first data flow according to the first identifier carried in the packet of the first data flow; wherein the first identifier includes

[0228] the first DBV identifier, the first DBV identifier indicates the value of the DBV of the first data flow

[0229] Here, the first identifier can be carried in the GTP-U packet header of the first data flow. The start identifier can be understood as a start indication, the second identifier can be understood as a duration indication, and the end identifier can be understood as an end indication. In the case where the first identifier comprises a first DBV identifier, the QoS rule indicating that the RAN schedules resources and / or provides QoS guarantees according to the value of the DBV of the first data flow; the first DBV identifier can be understood as a DBV indication of the first data flow or a DBV indication within the duration. In the case where the first identifier comprises a second DBV identifier, the QoS rule indicating that the RAN schedules resources and / or provides QoS guarantees according to the QoS within the duration of the first data flow, and the second DBV identifier can be understood as a QoS indication of the duration of the first data flow.

[0230] Step 4: The SMF sends sixth information to the UPF.

[0231] Here, the sixth information represents indication information related to data processing of the first data flow, and the sixth information can be understood as a PDR and / or a FAR. The sixth information comprises one or more of the following:

[0232] A first indication, the first indication being used to instruct the UPF to identify packets of the first data flow;

[0233] A third indication, the third indication being used to instruct the UPF to mark different DBV identifiers for different packets, wherein the different DBV identifiers correspond to different values of DBV;

[0234] A fourth indication, the fourth indication being used to instruct the UPF to add a third identifier in the packets of the first data flow. The third identifier comprises one or more of the following:

[0235] A QoS identifier of the duration of the first data flow;

[0236] A second DBV identifier, the second DBV identifier indicating a value of DBV within the duration of the first data flow;

[0237] A start identifier, the start identifier indicating a first packet within the duration of the first data flow;

[0238] A second identifier, the second identifier indicating a packet within the duration of the first data flow;

[0239] An end identifier, the end identifier indicating a last packet within the duration of the first data flow.

[0240] For example, the SMF sends data processing indication information such as PDR / FAR to the UPF, instructing the UPF to mark the third identifier for the packet in the starting duration for the second opening requirement, for example, marking the QoS identifier of the duration of the first data flow (second opening QoS indication), or marking the start identifier (start indication), or marking the second identifier (duration), or marking the end identifier (second opening end indication), or marking the second DBV identifier (second opening DBV indication). As shown in FIG. 9, the third identifier can be carried in the packet header (GTP-U header) of the first data flow.

[0241] Step 5: The UPF transmits downlink data to the RAN.

[0242] Step 6: The RAN schedules resources and / or provides QoS guarantee according to the fifth information in the duration of the first data flow.

[0243] Here, the RAN can use the QoS rule of the first data flow to schedule network resources and / or provide QoS guarantee in the duration of the first data flow, and use the QoS rule of the second data flow to schedule network resources and / or provide QoS guarantee at other times. The other times refer to times other than the duration of the first data flow. For example, in the duration of the first data flow, the RAN schedules resources and / or provides QoS guarantee according to the third identifier carried by the packet of the first data flow.
