[0093] In the various embodiments of the present application, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution.

However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0096] Before the specific description of the embodiments of the present application, the execution subject of the embodiments of the present application is described:

[0097] Optionally, the first network function includes a PCF (Policy Control Function).

[0098] Optionally, the second network function includes SMF (Session Management Function).

[0099] Optionally, the third network function includes UPF (User Plane Function) or PSA (PDU Session Anchor) UPF.

[0101] Optionally, the fourth network function includes an Intermediate UPF (I-UPF, relay user plane function).

[0102] like Figure 1As shown, a service flow processing method in an embodiment of the present application is performed by a first network function, and includes the following steps:

[0103] S101, obtaining first information; wherein, the first information is used for identifying or detecting multiple service flows, and the multiple service flows belong to the same end-to-end transmission connection.

[0104] Optionally, the PCF obtains the first information through AF (Application Function).

[0105] Optionally, the PCF obtains the first information from the AF through a Network Exposure Function (NEF); specifically, the AF sends the first information to the NEF, and the NEF forwards the first information to the PCF.

[0106] Optionally, the multiple service flows use the same IP quintuple.

[0107] Optionally, the service flow is a multimodal service flow, including a video stream, an audio stream, a gesture stream and a tactile stream.

[0108] Optionally, the first information includes at least one of the following:

[0109] Business flow classification information;

[0110] Business flow filtering information;

[0111] Packet filtering information;

[0112] Business flow identification information;

[0113] Additional packet filtering information;

[0114] Business flow direction: it should be noted that the business flow direction to which the first information applies includes uplink and / or downlink business flow direction;

[0115] The information that needs to be sent to the UE (User Equipment) through explicit signaling, it can be understood that if the first information includes the information that needs to be sent to the UE through display signaling, then the information that needs to be sent to the UE through display signaling is sent to the UE through display signaling, otherwise, it does not need to be sent to the UE through display signaling;

[0116] The correspondence between the service flow classification information and the QoS parameters;

[0117] The relationship between different business flows.

[0118] Optionally, the service flow classification information includes at least one of the following:

[0119] Service type information;

[0120] Media type information, including at least one of a video stream type, an audio stream type, a gesture stream information, and a tactile stream type;

[0121] The media service layer processes information, such as the XR service base layer or the XR service enhancement layer;

[0122] Service stream protocol identification information, such as different QUIC media stream IDs in QUIC (Quick UDP Internet Connection) used as multi-stream identification information to distinguish streams carrying different media types; different protocol types, including Real-time Transport Protocol (RTP) and Secure Real-time Transport Protocol (SRTP), can be identified through protocol header fields.

[0123] It should be noted that, since the service flow classification information includes at least one of the following: service classification information, media type information, media service layer processing information, and service flow protocol identification information, the service flow classification information can be understood as a service flow multiplexed information.

[0124] In addition, the specific information content included in the service flow filtering information, packet filtering information, service flow identification information and additional packet filtering information in the above-mentioned first information is the same as the specific information content included in the service flow classification information. In order to avoid repetition, it will not be repeated here.

[0125] Furthermore, the first information may also include other information, which needs to include at least one of the following: service classification information, media type information, media service layer processing information, service flow protocol identification information, and the other information is not specifically limited here. Optionally, the QoS parameter includes at least one of the following:

[0126] General QoS parameters, including at least one of Packet Delay Budget (PDB), Packet Error Rate (PER), Maximum Data Burst Volume (MDBV), and Guaranteed Flow Bit Rate (GFBR);

[0128] Multiple levels of QoS (alternative QoS) parameters.

[0129] Optionally, the association relationship between different service flows includes at least one of the following:

[0130] A first relationship, wherein the first relationship is used to indicate that the first service flow and the second service flow need to be collaboratively controlled for QoS. It should be noted that the first service flow and the second service flow are multimodal data flows of the same service and need to be collaboratively controlled for QoS, thereby achieving QoS collaborative guarantee requirements;

[0131] The second relationship is used to indicate that at least part of the third business flow is allowed to be discarded, and the third business flow includes repair data of the source data business flow. For example, FEC is used for the XR stream, wherein source data packets and repair data packets can be placed in different streams and marked during transmission. Here, the source data packets are placed in the source data business flow, and the repair data packets are placed in the third business flow. Packet loss processing is performed according to the transmission situation. If the source data business flow is completely transmitted, the part of the repair data corresponding to the source data business flow in the third business flow can be discarded; otherwise, it cannot be discarded, and the part of the repair data corresponding to the source data business flow in the third business flow is required.

[0132] S102: Determine mapping information between the multiple service flows and QoS flows according to the first information.

[0133] Optionally, the mapping information includes at least one of the following:

[0134] The multiple service flows are mapped to multiple QoS flows;

[0135] The multiple service flows are mapped to the same QoS flow.

[0136] It should be noted that if mapped to multiple QoS flows, PCF needs to combine the mapping relationship between service flow classification information and QoS parameters, and bind common QoS parameters, PDU set-related QoS parameters or multi-level QoS parameters to different QoS flows respectively.

[0137] If it is mapped to the same QoS stream, for example, the media substreams of the base layer and the enhancement layer are mapped to the same QoS stream, the PCF configures general QoS parameters, PDU set-related QoS parameters or multi-level QoS parameters in combination with the service stream classification information, indicating the information identifying multi-stream multiplexing.

[0138] In an embodiment of the present application, the PCF determines mapping information between multiple service flows and QoS flows, thereby deciding on multiplexing processing of the service flows.

[0139] S103: Send the first information and the mapping information to a second network function.

[0140] In an embodiment of the present application, the PCF sends the first information and the mapping information to the SMF, so that the SMF can perform multi-stream multiplexing according to the first information and the mapping information, map multiple media streams in the same service flow to one or more QoS flows, and generate QoS template (QoS profile) information of the QoS flows mapped to the multiple service flows, and send the QoS template information to the RAN to complete QoS guarantee.

[0141] Optionally, the PCF sends policy information carrying the first information and the mapping information to the SMF.

[0142] It should be noted that the policy information carrying the first information and the mapping information may be a Policy and Charging Control Rule (PCC Rule).

[0143] As an optional embodiment, the above method further includes:

[0144] Determine association identifiers of different QoS flows according to the association relationship between the different service flows;

[0145] The association identifier is sent to the second network function.

[0146] It should be noted that if the first information also includes the association relationship between different business flows, the PCF can determine the association identifiers of different QoS flows based on the association relationship between different business flows, for example, based on the association relationship between the key flow and the dependent flow, or the association relationship between the source data flow and the repair flow, respectively identify them to different QoS flows and send the association identifiers to the SMF.

[0147] like Figure 2 As shown, a service flow processing method in an embodiment of the present application is performed by a second network function, and includes the following steps:

[0148] S201, receiving first information sent by a first network function and mapping information of multiple service flows and QoS flows; wherein the first information is used to identify or detect multiple service flows, and the multiple service flows belong to the same end-to-end transmission connection.

[0149] Optionally, the first information includes at least one of the following:

[0150] Business flow classification information;

[0151] Business flow direction;

[0152] Information that needs to be sent to the terminal via explicit signaling;

[0153] The correspondence between the service flow classification information and the QoS parameters;

[0154] The relationship between different business flows.

[0155] Optionally, a PCC Rule carrying the first information and mapping information and sent by the first network function is received.

[0156] S202: Generate QoS template information of the QoS flow mapped to the multiple service flows according to the first information and the mapping information.

[0157] S203: Send the QoS template information to the network side device.

[0158] Optionally, the QoS template information is sent to the network side device via AMF (Access and Mobility Management Function).

[0159] As an optional embodiment, the above method further includes:

[0160] Determining association identifiers of different QoS flows according to the association relationship between the different service flows, or receiving association identifiers of different QoS flows sent by the first network function;

[0161] Send the association identifier to the network side device.

[0162] It should be noted that if the received first information also includes the association relationship between different business flows, the association identifiers of different QoS flows can be determined based on the association relationship between different business flows; if the received first information does not include the association relationship between different business flows, the association identifiers of different flows sent by the PCF can be received and sent to the SMF.

[0163] It should also be noted that the association relationship between the different service flows includes at least one of the following:

[0164] A first relationship, wherein the first relationship is used to indicate that the first service flow and the second service flow require collaborative QoS control;

[0165] The second relationship is used to indicate that at least part of the third service flow is allowed to be discarded, and the third service flow includes repair data of the source data service flow.

[0166] Therefore, the association identifiers of different QoS flows can be used to indicate the above-mentioned first relationship and / or second relationship.

[0209] S401, obtaining third information, where the third information is used for business flow identification or detection.

[0210] Optionally, the acquiring the third information includes:

[0211] If the third information is second information, receiving the second information sent by the second network function, where the second information is used for service flow identification or detection; or,

[0212] If the third information is the fourth information, the fourth information transmitted through the service layer or the application layer is received, and the fourth information is used for service flow identification or detection.

[0213] Optionally, the second information includes at least one of the following:

[0219] Optionally, the fourth information includes at least one of the following:

[0220] Business flow classification information;

[0221] Business flow filtering information;

[0222] Packet filtering information;

[0223] Business flow identification information;

[0224] Additional packet filtering information.

[0225] In the embodiment of the present application, the terminal obtains the third information, which may be the second information sent by the third network function, or the fourth information transmitted through the service layer or the application layer. Here, the terminal may interact with the application server (AS) through the application layer to receive the fourth information.

[0226] As an optional embodiment, the above method further includes:

[0227] When the target traffic flow is received, packet inspection is performed.

[0228] It should be noted that both the terminal and the third network function can perform packet detection when receiving the target service flow.

[0229] As an optional embodiment, the execution packet detection includes at least one of the following:

[0230] Identify, based on the third information, that the data packet belongs to a specific session or data flow;

[0231] Generating classification identification information of the target service flow, where the target service flow is one or more of a plurality of service flows, and the plurality of service flows belong to the same end-to-end transmission connection;

[0232] Send the classification identification information to the network side device.

[0233] In an embodiment of the present application, the terminal can receive a QoSRule carrying second information sent by a second network function to implement packet detection. When identifying that the data packet belongs to a specific session or data flow, the terminal can identify the target business flow as one or more of multiple business flows according to the business flow classification information in the second information, map the target business flow to one or more business flows, and generate classification identification information of the target business flow, and send the classification identification information as PDU Set information to the network side device.

[0234] like Figure 5 As shown, a service flow processing method of an embodiment of the present application is performed by a network side device, including the following steps:

[0235] S501, receiving QoS template information of a QoS flow mapped to multiple service flows sent by a second network function, wherein the multiple service flows belong to the same end-to-end transmission connection.

[0236] S502: Receive classification identification information of a target service flow sent by a third network function or a terminal, where the target service flow is one or more of the multiple service flows.

[0237] S503: When the target service flow is received, determine the QoS parameters of the target service flow according to the QoS template information.

[0238] In an embodiment of the present application, the network side device can determine the QoS parameters of the target service flow based on the QoS template information, and adjust the resources in a fine-grained manner, thereby achieving QoS guarantee for the target service flow.

[0239] As an optional embodiment, the above method further includes:

[0240] receiving association identifiers of different QoS flows sent by the second network function;

[0241] The service flow associated with the target service flow is processed according to the association identifier and the QoS parameter.

[0242] In the embodiment of the present application, the association identifiers of different QoS flows are used to indicate the association relationship between different service flows. Since the association relationship between different service flows includes at least one of the following:

[0243] A first relationship, wherein the first relationship is used to indicate that the first service flow and the second service flow require collaborative QoS control;

[0244] The second relationship is used to indicate that at least part of the third service flow is allowed to be discarded, and the third service flow includes repair data of the source data service flow.

[0245] Therefore, the association identifiers of different QoS flows are used to indicate the above-mentioned first relationship and / or second relationship. The network side equipment can further implement QoS guarantee of the target service flow according to the association identifiers of different QoS flows, achieve the collaborative guarantee effect of QoS flows, or implement packet loss processing.

[0246] For example, sub-streams of different media types need to be transmitted in a coordinated manner. For example, the service enhancement layer stream depends on the transmission of the basic layer stream. According to the identified key streams and dependent streams, the transmission of associated streams can be coordinated to ensure that the key streams are transmitted in a coordinated manner. When the key stream is lost, the data identified as the dependent stream can be discarded.

[0247] For example, FEC is used for XR streams, in which source data packets and repair data packets can be placed in different streams during transmission. The stream of source data packets and the stream of repair data packets are identified, and packet loss processing is performed according to the transmission situation. If the source data packet is transmitted completely, the repair part can be discarded; otherwise, the repair part is required.

[0248] Therefore, the service flow processing method of the embodiment of the present application is aimed at multiple service flow identification scenarios of XR services. The first information is provided to the core network (i.e., the first network function, the second network function, and the third network function) through AF. The core network performs multiple service flow identifications and QoS flow mappings based on the first information. The network side device determines the QoS parameters of the target service flow based on the configuration of the core network, so as to effectively match the XR service flow when it is transmitted within the same transport layer connection, and complete the service flow identification and QoS flow mapping based on the first information.

At the same time, the SMF generates second information according to the first information, and sends the second information to the UE.

[0255] It should be noted that if the AF does not provide the first information, S601 to S605 are not executed, and the UE receives the fourth information transmitted through the application layer.

[0256] S606, when receiving the target service flow, the UE identifies that the data packet belongs to a specific session or data flow according to the second information or the fourth information; generates classification identification information of the target service flow; and sends the classification identification information of the target service flow to the RAN.
