Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method, apparatus, and device for adjusting the quality of service of multi-stream data. Background Art

[0002] With the increasing powerful display and processing capabilities of mobile terminals, the same user can simultaneously process multiple Internet Protocol (IP) flows. For example, a Virtual Reality (VR) headset device utilizes the characteristics of a large Field of View (FOV) to use multiple windows to process multiple Application (APP) tasks and display multi-person video call images.

[0003] In an application scenario with multiple IP flows, a terminal can simultaneously process a large amount of data. However, for users, there are usually IP flows that are important to focus on and those that are less important. For example, in a multi-person call scenario, only the data when one or several people are speaking and presenting is important, or in multi-APP task processing, APP1 is mainly processed for a period of time, and when there is a need for APP2 data, APP2 is processed. At this time, the tags of important data switch between APP1 and APP2. Therefore, the importance of the user's perception of IP flows is different and changes with the user's needs. When the network resources on the base station side are limited, how to implement a fast and coordinated Quality of Service (QoS) guarantee strategy for multiple IP flows is a problem that needs to be solved.

[0097] To make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0098] In a scenario where a single user can process multiple IP flows simultaneously, there are two sources for multiple IP flows:

[0099] 1. Multiple IP flows come from data of multiple terminals of the same service. For example, in a multi-person video call scenario, as Figures 1 to 3 shown; usually, the flow data of each terminal is aggregated to an application server (AS) and then distributed. It can be multiple IP flows, as Figure 3 shown; or it can form a single IP flow, as Figure 2 shown.

[0100] 2. Multiple IP flows can also come from different APP services. For example, when a user is watching an entertainment video, they are also watching the home surveillance video simultaneously.

[0101] It should be noted that in the downlink scenario, when these IP flows reach the User Plane Function (UPF) entity, they are divided into the same or different QoS flows and transmitted to the Radio Access Network (RAN) side, and then mapped to the Data Radio Bearer (DRB). When different IP flows are mapped to the same QoS flow, if the resources on the RAN side change and the QoS guarantee needs to be enhanced or reduced, the same resource adjustment strategy will be applied to multiple IP flows of the same QoS flow. The existing methods for adjusting QoS guarantee on the RAN side are as follows:

[0102] (1) Based on the QoS rules regenerated by the Policy Control Function (PCF) on the core network side, the Session Management Function (SMF) allocates a new Quality of Service Flow Identifier (QoS flow ID, QFI) and maps it to the corresponding QoS flow, generating a new QoS profile and sending it to the RAN side for QoS guarantee on the wireless side;

[0103] (2) The Application Function (AF) on the core network side configures the QoS profile and the optional Alternative QoS profile(s) for the service data and notifies the RAN. When the RAN resources cannot meet the QoS profile, the Alternative QoS profile(s) are selected in sequence to ensure the transmission of service data.

[0104] Since the existing IP flows are mapped to the same QoS flow according to the QoS mapping rules, the base station cannot perform adjustments at the IP flow granularity. Therefore, how the base station identifies different IP flows is a problem that needs to be solved.

[0105] In the case where the base station identifies the IP flow, if it is necessary to adjust the QoS guarantee, the response of the base station is not timely if the above-mentioned QoS policy reconfigured by the core network is used. If the above-mentioned Alternative QoS profile(s) are used, dynamic collaborative adjustment cannot be performed for multiple user flows. Therefore, how to implement a fast and collaborative QoS guarantee strategy for multiple IP flows is a problem that needs to be solved.

[0106] To solve the above problems, the present invention provides a method, apparatus, and device for service quality adjustment of multi-stream data. Among them, the method and the apparatus are based on the same application concept. Since the principles of problem-solving by the method and the apparatus are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be described again.

[0107] As Figure 4 shown, an embodiment of the present invention provides a method for service quality adjustment of multi-stream data, and this method is applied to a base station. Among them, this method may include:

[0108] Step 401, receiving a Quality of Service flow (QoS flow) sent by a first network function entity;

[0109] Here, the first network function entity is a User Plane Function (UPF) entity. Specifically, the first network function entity sends the QoS flow to the base station based on the mapping rule from IP flow to QoS flow. Among them, this QoS flow includes multiple IP flows.

[0110] Step 402, when the radio resources cannot meet the QoS guarantee of the QoS flow, identifying the IP flow identifiers corresponding to each of the multiple Internet Protocol flows (IP flows) in the QoS flow;

[0111] Here, the situation that the radio resources cannot meet the QoS guarantee of the QoS flow specifically means that the radio resources cannot achieve the Guaranteed Flow Bit Rate (GFBR), Packet Delay Budget (PDB), Packet Error Rate (PER), etc. corresponding to the QoS guarantee of the QoS flow.

[0112] It should be noted that when the radio resources meet the QoS guarantee of the QoS flow, the base station (specifically, the Service Data Adaptation Protocol (SDAP) layer of the base station) transmits the QoS flow according to the mapping rule from QoS flow to Data Radio Bearer (DRB).

[0113] Step 403, adjusting the QoS guarantee of the multiple IP flows according to the IP flow identifiers corresponding to each of the multiple IP flows and the first corresponding relationship between the IP flow identifier and the attention level of the terminal to the IP flow; where the IP flow identifier is used to identify the IP flow, and the attention level of the terminal to the IP flow is used to characterize the importance of the IP flow.

[0114] Here, the first correspondence relationship can be pre-stored in the base station in the form of a table. This table can be referred to as the IP flow status table.

[0115] It should be noted that based on the first correspondence relationship, the attention level of the terminal to each of the multiple IP flows can be obtained, that is, the importance level of each IP flow can be obtained; according to the attention level of the terminal to each IP flow, the QoS guarantee of the IP flow is adjusted to ensure the timely transmission of the IP flow with a high importance level, thereby guaranteeing the user experience.

[0116] In an optional embodiment, in step 402 above, identifying the IP flow identifier corresponding to each of the multiple Internet protocol flows (IP flows) in the QoS flow includes:

[0117] Step 4021, detecting each IP data packet of the QoS flow;

[0118] Step 4022, for each of the IP data packets, by parsing the header of the IP data packet, obtaining the IP flow identifier corresponding to the IP data packet; wherein, one or more IP data packets with the same IP flow identifier form an IP flow;

[0119] It should be noted that the first network function entity adds the IP flow identifier to the header of the IP data packet in the IP flow, so the base station side can obtain the IP flow identifier by parsing the header of the IP data packet.

[0120] Step 4023, based on the IP flow identifier corresponding to the IP data packet, identifying the IP flow identifier corresponding to each of the multiple IP flows.

[0121] It should be noted that since one or more IP data packets with the same IP flow identifier form an IP flow, based on the IP flow identifier corresponding to the IP data packet, the IP flow identifier corresponding to each of the multiple IP flows can be identified.

[0122] Through the implementation manner of this embodiment, the IP flow identifier corresponding to each of the multiple IP flows can be identified, and then the QoS guarantee adjustment based on the IP flow granularity can be realized.

[0123] In an optional embodiment, in step 403 above, adjusting the QoS guarantee of the multiple IP flows according to the IP flow identifier corresponding to each of the multiple IP flows and the first correspondence relationship between the IP flow identifier and the attention level of the terminal to the IP flow includes:

[0124] Step 4031: Determine the attention level of each of the multiple IP flows to the IP flow according to the IP flow identifier corresponding to each of the multiple IP flows and the first corresponding relationship.

[0125] Step 4032: In the order from low to high of the attention level of each of the multiple IP flows to the IP flow, for the corresponding IP flow in sequence, reduce the QoS guarantee of the IP flow based on the optional QoS profile.

[0126] That is, the lower the attention level of the terminal to the IP flow, the less important the IP flow is. Therefore, the QoS guarantee of the IP flow is preferentially reduced. In this way, the IP flows with high importance are guaranteed to be transmitted in time.

[0127] Optionally, reducing the QoS guarantee of the IP flow includes at least one of the following:

[0128] Map the IP flow to a lower-level data radio bearer (DRB);

[0129] Discard the IP flow;

[0130] Shorten the duration of the timer for discarding the IP flow.

[0131] In an optional embodiment, the method of the present invention further includes:

[0132] 1) Receive first indication information reported by the terminal, where the first indication information is used to indicate a change in the importance of the IP flow to the terminal;

[0133] Specifically, this step may include:

[0134] Receive a radio resource control (RRC) reconfiguration message sent by the terminal; wherein, the RRC reconfiguration message includes the first indication information; or,

[0135] Receive terminal assistance information sent by the terminal, where the terminal assistance information includes the first indication information.

[0136] That is, the terminal realizes the transmission of the first indication information by sending an RRC Reconfiguration message or UE Assistance Information.

[0137] 2) Update the first corresponding relationship according to the first indication information.

[0138] Here, according to the change in the importance level of the IP flow to the terminal indicated by the first indication information, the terminal updates the attention level of the IP flow to the terminal, thereby realizing the update of the first correspondence relationship.

[0139] Subsequently, based on the updated first correspondence relationship, the QoS guarantee of multiple IP flows is adjusted; in this way, the QoS guarantee of the IP flow can be dynamically adjusted based on the importance perceived by the user for the IP flow.

[0140] In an optional embodiment, the method of the present invention may further include:

[0141] A1) Receive the second correspondence relationship between the IP flow attribute information and the IP flow identifier sent by the second network function entity, where the IP flow attribute information corresponding to different IP flows is different;

[0142] Here, the second network function entity is a PCF entity. The IP flow attribute information can be used to distinguish different IP flows. The IP flow attribute information includes but is not limited to APP ID, source address.

[0143] Optionally, the IP flow attribute information is sent by the third network function entity to the second network function entity; the IP flow identifier is generated by the second network function entity based on the IP flow attribute information. It should be noted that the third network function entity is an AF entity.

[0144] Here, the third network function entity (AF entity) sends the IP flow attribute information corresponding to each IP flow to the second network function entity (PCF entity) through the network exposure function. It should be noted that in addition to sending the IP flow attribute information corresponding to each IP flow to the second network function entity (PCF entity), the third network function entity (AF entity) also sends a QoS configuration file to the second network function entity (PCF entity).

[0145] Specifically, the QoS configuration file includes a QoS profile and alternative QoS profile(s). Among them, the priority of the alternative QoS profile(s) is lower than that of the QoS profile.

[0146] It should be noted that the base station also receives the QoS configuration file sent by the second network function entity.

[0147] A2) Obtain the first correspondence relationship according to the second correspondence relationship.

[0148] Here, the first correspondence relationship is stored in the base station in the form of a table. Specifically, this table includes the IP flow identifier (IPflow Identify, IPFI) and the attention level of the terminal to the IP flow (IPF_Level). It should be noted that the attention level of the terminal to the IPflow is initialized to 0. See Table 1 below.

[0149] Table 1

[0150] IP flow identifier (IPFI) Terminal's concern level for IP flow (IPF_Level) 1 0 2 0 3 0

[0151] The base station maintains this table, and subsequently, the base station will update the attention level of the terminal to the IP flow in this table based on the first indication information reported by the terminal.

[0152] In an optional embodiment, the method of the present invention further includes:

[0153] Report the QoS guarantee of the adjusted multiple IP flows to the first network function entity.

[0154] That is, when the base station changes the IP flow resource management, it uploads a notice to the core network (specifically, the first network function entity on the core network side), counts the changes of different IP flows, and is used to be opened to the application layer for subsequent optimization of the resource adjustment of multiple service links.

[0155] The service quality adjustment method for multi-flow data in the embodiment of the present invention receives the quality of service flow QoS flow sent by the first network function entity; when the radio resources cannot meet the QoS guarantee of the QoS flow, it identifies the IP flow identifiers corresponding to the multiple Internet protocol flows IP flows in the QoSflow; according to the IP flow identifiers corresponding to the multiple IP flows and the first correspondence relationship between the IP flow identifier and the attention level of the terminal to the IP flow, it adjusts the QoS guarantee of the multiple IP flows; wherein, the IP flow identifier is used to identify the IP flow, and the attention level of the terminal to the IP flow is used to characterize the importance of the IP flow. In this way, by using the IP flow identifier and through the first correspondence relationship between the IP flow identifier and the attention level of the terminal to the IP flow, when the network resources on the base station side are limited, it can quickly and collaboratively adjust the QoS guarantee strategies of multiple IP flows and improve the user experience.

[0156] As Figure 5 shown, the embodiment of the present invention further provides a service quality adjustment method for multi-flow data, and this method is applied to the first network function entity. The first network function entity may be a UPF entity. Among them, this method may include:

[0157] Step 501: Send a Quality of Service flow (QoS flow) to the base station. The QoS flow includes IP flow identifiers corresponding to multiple Internet Protocol flows (IP flows). The IP flow identifiers corresponding to the multiple IP flows are used to adjust the QoS guarantee for the multiple IP flows.

[0158] It should be noted that the first network function entity sends the QoS flow to the base station based on the mapping rule from IP flow to QoS flow.

[0159] Here, the first network function entity provides, by sending the QoS flow, the IP flow identifiers corresponding to the multiple IP flows in the QoS flow to assist the base station in adjusting the QoS guarantee for the multiple IP flows when the radio resources cannot meet the QoS guarantee of the QoS flow, so as to implement a fast and coordinated QoS guarantee strategy for the multiple IP flows and improve the user experience.

[0160] In an optional embodiment, the method of the present invention further includes:

[0161] Receiving a second correspondence between IP flow attribute information and IP flow identifiers sent by a second network function entity;

[0162] Among them, the IP flow attribute information corresponding to different IP flows is different. The IP flow attribute information is sent by a third network function entity to the second network function entity. The IP flow identifier is generated by the second network function entity based on the IP flow attribute information.

[0163] Here, the second network function entity may be a PCF entity. The third network function entity may be an AF entity. The IP flow attribute information can be used to distinguish different IP flows. The IP flow attribute information includes, but is not limited to, APP ID and source address.

[0164] Here, the third network function entity (AF entity) sends the IP flow attribute information corresponding to each IP flow to the second network function entity (PCF entity) through the network exposure function. It should be noted that in addition to sending the IP flow attribute information corresponding to each IP flow to the second network function entity (PCF entity), the third network function entity (AF entity) also sends a QoS profile to the second network function entity (PCF entity).

[0165] Specifically, the QoS configuration file includes a QoS profile and alternative QoS profile(s). Among them, the priority of the alternative QoS profile(s) is lower than that of the QoS profile.

[0166] It should be noted that the first network function entity also receives the QoS configuration file sent by the second network function entity.

[0167] In an optional embodiment, the method of the present invention further includes:

[0168] B1) Receiving a plurality of the IP flows sent by the service server;

[0169] B2) Generating a packet filtering template according to the IP flow attribute information; each of the IP flows corresponds to a packet filtering template;

[0170] B3) For each of the IP flows, identifying the IP data packets in the IP flow according to the packet filtering template; and adding the IP flow identifier of the IP flow to the header of the IP data packet.

[0171] That is to say, when an IP flow passes through the first network function entity (UPF entity), the first network function entity performs packet filtering using the packet filtering template generated from the IP flow attribute information, thereby identifying the IP data packets in the IP flow and adding the IP flow identifier to the header of the IP data packet, such as the GTP-U header, see Figure 6 . At this time, the mapping rule from the IP flow to the QoS flow is not changed.

[0172] Through the processing of this embodiment, it can be ensured that the QoS flows sent by the first network function entity to the base station contain the IP flow identifiers corresponding to the respective IP flows.

[0173] In an optional embodiment, the method of the present invention further includes:

[0174] Receiving the QoS guarantee of the adjusted multiple IP flows reported by the base station.

[0175] That is, when the base station changes the IP flow resource management, it uploads a notice to the core network (specifically, the first network function entity on the core network side), and counts the changes of different IP flows for opening to the application layer for subsequent optimization of the resource adjustment of multiple service links.

[0176] The method for adjusting the quality of service of multi-flow data according to the embodiment of the present invention includes sending a Quality of Service flow (QoS flow) to a base station; wherein, the QoS flow includes IP flow identifiers corresponding to multiple Internet Protocol flows (IP flows) respectively; the IP flow identifiers corresponding to the multiple IP flows are used to adjust the QoS guarantee of the multiple IP flows, so as to assist the base station in adjusting the QoS guarantee of the multiple IP flows when the radio resources cannot meet the QoS guarantee of the QoS flow, thereby realizing a fast and coordinated QoS guarantee strategy for the multiple IP flows and improving the user experience.

[0177] As Figure 7 shown, the embodiment of the present invention provides a method for adjusting the quality of service of multi-flow data, and this method is applied to a terminal. Wherein, this method may include:

[0178] Step 701, when the change of the service state meets a preset condition, report first indication information to the base station; wherein, the first indication information is used to indicate the change of the importance degree of the Internet Protocol flow (IP flow) to the terminal; the change of the importance degree of the IP flow to the terminal is used for the base station to update the first corresponding relationship between the IP flow identifier and the attention level of the terminal to the IP flow; the first corresponding relationship is used to adjust the QoS guarantee of the multiple IP flows.

[0179] By reporting the first indication information from the terminal to the base station, the change of the importance degree of the indicated IP flow to the terminal is used by the base station side to update the first corresponding relationship, so as to assist the base station in adjusting the QoS guarantee of the multiple IP flows when the radio resources cannot meet the QoS guarantee of the QoS flow, thereby realizing a fast and coordinated QoS guarantee strategy for the multiple IP flows and improving the user experience.

[0180] Optionally, the change of the service state meeting the preset condition includes at least one of the following:

[0181] The display window of the application program corresponding to the IP flow is enlarged or reduced; here, if it is enlarged, the attention level of the terminal to the IP flow increases; if it is reduced, the attention level of the terminal to the IP flow decreases.

[0182] The overlap rate between the display position of the IP flow on the terminal screen and the area projected by the field of view angle of the terminal camera onto the terminal screen is greater than a first threshold or less than a second threshold; here, if the overlap rate is greater than the first threshold (such as 80%), the attention level of the terminal to the IP flow increases; if the overlap rate is less than the second threshold (such as 20%), the attention level of the terminal to the IP flow decreases.

[0183] The frequency of paying attention to the IP flow within a preset duration is greater than a third threshold value;

[0184] A switch occurs between the terminal background program and the terminal foreground program. Here, the attention level of the terminal foreground program is higher.

[0185] The above-mentioned changes in the service state that meet the preset conditions all reflect the change in the importance level of the IP flow to the terminal, that is, the change in the attention level of the terminal to the IP flow.

[0186] In an optional embodiment, in step 701 above, the reporting of the first indication information to the base station includes:

[0187] Sending a Radio Resource Control (RRC) reconfiguration message to the base station; wherein, the RRC reconfiguration message includes the first indication information; or,

[0188] Sending terminal assistance information to the base station, and the terminal assistance information includes the first indication information.

[0189] That is, the terminal realizes the transmission of the first indication information by sending an RRC Reconfiguration message or UEAssistanceInformation.

[0190]

[0191] In the above example, IPF_LevelUpdate is the first indication information. For the specific IPF_LevelUpdatelist, please refer to Table 2 below.

[0192] Table 2

[0193] IP flow identifier (IPFI) IPF_LevelUpdate N 0or 1

[0194] Among them, 0 indicates that the attention level of the terminal to the IP flow decreases, and 1 indicates that the attention level of the terminal to the IP flow increases.

[0195] In an optional embodiment, the method of the present invention further includes:

[0196] Receiving a second correspondence relationship between the IP flow attribute information and the IP flow identifier sent by a second network function entity;

[0197] Among them, the IP flow attribute information corresponding to different IP flows is different; the IP flow attribute information is sent by a third network function entity to the second network function entity; the IP flow identifier is generated by the second network function entity based on the IP flow attribute information.

[0198] In this embodiment, the second corresponding relationship can assist the terminal in generating the first indication information.

[0199] Here, the second network function entity is a PCF entity. The IP flow attribute information can be used to distinguish different IP flows. The IP flow attribute information includes, but is not limited to, the APP ID and the source address.

[0200] Here, the third network function entity (AF entity) sends the IP flow attribute information corresponding to each IP flow to the second network function entity (PCF entity) through the network exposure function. It should be noted that in addition to sending the IP flow attribute information corresponding to each IP flow to the second network function entity (PCF entity), the third network function entity (AF entity) also sends a QoS profile to the second network function entity (PCF entity).

[0201] Specifically, the QoS profile includes a QoS profile and alternative QoS profile(s). Among them, the priority of the alternative QoS profile(s) is lower than that of the QoS profile.

[0202] It should be noted that the terminal also receives the QoS profile sent by the second network function entity.

[0203] Next, through Figure 8 the service data transmission schematic diagram of the method of the present invention shown below, the design principle of the method of the present invention will be described. Specifically as follows:

[0204] I. Before service data transmission:

[0205] (1) The AF sends a QoS profile to the PCF on the core network side through the network exposure function, and provides the core network PCF with "QoS reference" parameters, including IP flow attribute information.

[0206] Among them, the QoS profile includes a QoS profile and alternative QoS profile(s). The priority of the alternative QoS profile(s) should be lower than that of the QoS profile.

[0207] The IP flow attribute information includes: information used to distinguish each IP flow, such as the APP id, source address, etc.

[0208] (2) The PCF generates an IP flow identifier (IPFI), such as 0, 1, 2, 3, based on the received IP flow attribute information. It notifies the UPF, RAN (base station side), and UE of the correspondence between the IP flow attribute information and the IP flow identifier, as well as the QoS profile.

[0209] (3) The RAN establishes an IP flow status table based on the received information, which is the first correspondence described in the embodiments of the present invention. The table includes the IP flow identifier (IPFI), the attention level of the terminal to the IP flow (IPF_Level), etc. The initialization of the terminal to the IP flow is 0.

[0210] II. During service transmission:

[0211] (1) A terminal receives multiple IP flows simultaneously. When the IP flow passes through the core network UPF, the UPF performs packet filtering using the PDR (packet filtering template) generated from the IP flow attribute information, identifies the IP data packets in each IP flow, and marks the IPFI. The IPFI is added to the GTP-U header, and at this time, the mapping rule from the IP flow to the QoS flow remains unchanged.

[0212] (2) When the RAN side receives the QoS flow, it does not change the mapping from the QoS flow to the DRB when the radio resources can meet the QoS flow guarantee; when the radio resources are scarce, the SDAP layer detects each IP data packet of the QoS flow and checks the attention level of the terminal to the IP flow in the IP flow status table. It reduces the QoS guarantee of the corresponding IP flow according to the alternative QoS profile(s) from low to high. For example, it maps the IP flow to a lower-level RDB or discards it.

[0213] (3) During the entire service data transmission, the terminal decides the change in its attention level to the IP flow according to the change in the service state, and reports its change information IPF_LevelUpdate to the RAN side through the RRC signaling.

[0214] It should be understood that IPF_LevelUpdate is the first indication information described in the embodiments of the present invention. The IPF_LevelUpdate information can be added to the terminal auxiliary information UAI to indicate the change in the attention level of the terminal to the IP flow.

[0215] During the implementation process, by configuring the RRCReconfiguration message or the UEAssistanceInformation message, the UE is triggered to send the RRCReconfiguration message or the UAI message under specific conditions:

[0216] The RAN side updates the UE attention level corresponding to the IP flow according to the IPF_LevelUpdate. 0 means subtracting 1 from its IPF_Level (the terminal's attention level to the IP flow), and 1 means adding 1 to its IPF_Level.

[0217] Among them, the change of the service state meeting specific conditions can be that the display window of the APP corresponding to the IP flow is enlarged or reduced; enlargement means that the terminal's attention level to the IP flow increases, and reduction means a decrease; it can also be the change in the degree of coincidence between the position information of the IP flow in the VR display and the FOV after the user's head movement. When the degree of coincidence is greater than 80%, the terminal's attention level to the IP flow increases; when it is less than 20%, the terminal's attention level to the IP flow decreases; or the frequency of paying attention to the IP flow within a certain period of time is greater than a certain threshold; or it is the switch between the terminal's background program and the foreground program, and the foreground program has a higher attention level.

[0218] (4) When the base station's resource management of the IP flow changes, it uploads a notice to the core network, counts the changes of different IP flows, and is used to be opened to the application layer for subsequent optimization of the resource adjustment of multiple service links.

[0219] See Figure 9 , for the description of the VR multi-person call scenario. UE1 uses a VR headset to make a video call with UE2, UE3, and UE4. At the beginning, UE4 speaks and shows first. At this time, the user turns the head to the UE4 user. The service detects that the FOV of UE1 coincides with the UE4 window by more than the threshold of 80%. See Figure 10 , the network side and the terminal should perform the following interactions. When the radio resources are limited, the video data of UE4 should be preferentially guaranteed

[0220] Step 0, the protocol data unit PDU session is established;

[0221] Step 1, the AF sends the QoS profile and IP flow attribute information to the PCF through the network exposure function;

[0222] Steps 2-3, the PCF initiates a PDU session modification, generates a QoS profile, and issues it to the UPF and the RAN together with the IP flow attribute information; the RAN generates an IP flow status table based on the IP flow attribute information and initializes it;

[0223] After that, the service server AS downloads the data packets packets of UE2, UE3, and UE4;

[0224] Step 4, the terminal uploads IPF_LevelUpdate to the RAN;

[0225] Step 5, the RAN updates the IPF_Level of the UE4 IP flow to 1 according to IPF_LevelUpdate;

[0226] Here, IPF_Level is the terminal's attention level to the IP flow.

[0227] Step 6, when the UPF identifies the IP flow, it marks the IPFI in GTP-U and performs the mapping of the IP flow to the QoS flow;

[0228] After the data packets packets of UE2, UE3, and UE4 pass through the UPF, the data packets packets of UE2, UE3, and UE4 are downloaded to the RAN.

[0229] Step 7, when the RAN detects a shortage of radio resources, the SDAP layer identifies the IP flow and adjusts the QoS guarantee of the IP flows of UE2 and UE3, and preferentially downloads the IP flow of UE4.

[0230] Step 8, the RAN notifies the core network of the result of the IP flow resource adjustment.
