Description

Technical Field

[0001] (Cross-reference to Related Applications) This application claims the priority of Chinese Patent Application No. 202310362614.3 filed in China on April 4, 2023, and the entire content of the application is incorporated herein by reference.

[0002] This application belongs to the field of wireless communication technology, and specifically relates to a method for operating congestion information, an apparatus, and a communication device.

Background Art

[0003] In a 5G system (5G System, 5G S), there may be the following two methods for disclosing congestion information. Method 1 is that a Radio Access Network (RAN) monitors the congestion situation, transmits the percentage of the congestion level to a User Plane Function (UPF) via the user plane, and then the UPF discloses it via a service interface or an N4 interface. Method 2 is that the RAN monitors the congestion situation, transmits the percentage of data packets marked with congestion to the UPF via the user plane, and then the UPF selects the corresponding percentage of data packets in the congestion direction based on the received congestion information to set the congestion marking.

[0004] In the above two methods, the meanings of the percentages reported to the UPF are not the same. However, since what the RAN obtains is one instruction, the RAN cannot determine whether to report the percentage of the congestion situation information, which is the information for describing the congestion situation, or the percentage of the data packets requiring congestion marking, which is the information for describing the data packets requiring congestion marking. Moreover, the user plane function also cannot determine how to process the percentage information of the congestion-related signal congestion level reported.

[0032] Figure 1 shows a block diagram of a wireless communication system to which an embodiment of this application can be applied.

Here, the terminal 11 may be a mobile phone, tablet personal computer, laptop computer, notebook computer, personal digital assistant (PDA), palmtop computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, aircraft (flight vehicle), vehicle user equipment (VUE), shipboard equipment, pedestrian user equipment (PUE), smart home (home appliances with wireless communication capabilities, such as refrigerators, televisions, washing machines or furniture), game console, personal computer (PC), deposit machine or self-service machine, etc. Wearable devices include smartwatches, smart bands, smart earphones, smart glasses, smart accessories (such as smart bracelets, smart rings, smart necklaces, smart anklets, smart wristbands, and smart clothing).

For the purposes of this explanation, only a base station in an NR system is used as an example in the embodiments of this application, but this does not limit the specific type of base station.

[0034] To better understand the proposed technology presented in this application, we will first introduce the technology related to this application.

[0035] There are two possible methods for disclosing congestion information in a 5G system (5GS):

[0036] Figure 2 illustrates a method for disclosing congestion information in related technologies, which includes a Radio Access Network (RAN) monitoring congestion conditions, transmitting the percentage of congestion level to a User Plane Function (UPF) via the user plane, and the UPF further disclosing the information via a service interface or N4 interface.

[0037] Figure 3 illustrates another congestion information disclosure method in related technology, which includes the RAN monitoring congestion conditions, transmitting the percentage of data packets that mark congestion via the user plane to the UPF, and the UPF selecting data packets with the corresponding percentage in the congestion direction and setting congestion markings based on the received congestion information.

[0038] In the methods shown in Figures 2 and 3 above, the meaning of the percentages reported to the UPF is not the same, but the RAN receives only one instruction, which includes, for example, Quality of Service (QoS) parameters for monitoring congestion information. Therefore, the RAN cannot decide when to report the percentage of congestion level or the percentage of data packets marking congestion, and the UPF cannot understand whether the percentage is the percentage of congestion level or the percentage of data packets marking congestion, and as a result, the UPF cannot perform the corresponding processing operation.

[0039] Based on this, this application provides a method, apparatus, and communication device for manipulating congestion information. Below, the method for manipulating congestion information according to the embodiments of this application will be described in detail with reference to several embodiments and their application scenarios, with the help of the drawings.

[0040] First, we will explain and conceptually interpret the specific terminology used in this application.

[0041] In one embodiment of this application, "report" or "notice" represents one of "notice" and "transmission".

[0042] In one embodiment of this application, the monitoring (e.g., monitor) requirement includes at least one of supervision, detection, measurement, and reporting.

[0043] In one embodiment of this application, monitoring may be referred to as at least one of supervision, detection, and measurement.

[0044] In one embodiment of this application, a request for disclosure of XX information may be expressed as an order request for XX information. Disclosing or making disclosure of XX information may represent transmitting the XX information to a consumer ordering the XX information (e.g., a communication device, a communication network element as described herein).

[0045] Explicit Congestion Notification (ECN) is a technology that displays congestion notifications by marking data packets with congestion. When congestion occurs, the value of the ECN bit in the data packet is set to 11, indicating that a congestion occurred at the CE (Congestion Entrance).

[0046] This refers to the need to perform congestion CE reporting when lighter congestion occurs, in order to achieve low latency, low loss, and scalable throughput (L4S) in an ECN.

[0047] Explicit Congestion Notification (ECN) is an extension of the TCP / IP protocol, defined in RFC 3168 (2001). ECN supports end-to-end network congestion notification, as specifically shown in Figure 3.

[0048] In one embodiment of this application, the onset of congestion, the progression of congestion, and the occurrence of congestion mean the same thing.

[0049] In one embodiment of this application, congestion termination, no congestion, and no congestion occurrence all mean the same thing.

[0050] The congestion information to be disclosed includes congestion status information (e.g., congestion level) to be disclosed.

[0051] In one embodiment of this application, any one of the “information” in this application is information corresponding to a first QoS flow or a first data flow. For example, this includes, but is not limited to, QoS information corresponding to a first QoS flow or a first data flow, the following:

[0052] First information, second information, third information, fourth information, fifth information, first congestion information, second congestion information, third congestion information, first request information, second request information, information for requesting congestion monitoring, information for requesting disclosure of congestion information, information for requesting congestion marking operations to be performed on data packets, information for requesting monitoring of first congestion, information for requesting monitoring of second congestion, information for indicating the purpose of monitoring congestion.

[0053] For example, the first congestion information is the first congestion information corresponding to the first QoS flow or the first data flow. For example, the second congestion information is the second congestion information corresponding to the first QoS flow or the first data flow.

[0054] For example, the third congestion information is the third congestion information corresponding to the first QoS flow or the first data flow.

[0055] In one embodiment of this application, any one “request” in this application is a request corresponding to a first QoS flow or a first data flow.

[0056] In one embodiment of this application, the “data packet” in this application is a data packet corresponding to a first QoS flow or a first data flow.

[0057] In one embodiment of this application, “congestion” in this application is congestion corresponding to a first QoS flow or a first data flow.

[0058] The first data flow is the data flow that binds to the first QoS flow. The first QoS flow is a certain QoS flow.

[0059] In one embodiment of this application, congestion may be a situation in a packet-switched network where the number of transmitted packets is too large, resulting in reduced network transmission performance due to limited resources at the transmission nodes. When network congestion occurs, it generally results in data loss, increased delay, and reduced throughput, and in severe cases, can even cause a congestion collapse.

[0060] In one embodiment of this application, the congestion status information may be information indicating the congestion status, such as the start of congestion, the end of congestion, the congestion level, and the direction of congestion.

[0061] In one selective embodiment of this application, congestion monitoring may include at least one of congestion status monitoring and congestion status measurement and / or congestion status reporting. Congestion status includes at least one of congestion start or occurrence, congestion end or no congestion, congestion decrease, and congestion increase.

[0062] In one selective embodiment of this application, congestion occurring in the first object means that congestion has occurred in the data transmission in the first object.

[0063] In one selective embodiment of this application, the congestion status information of the first object is the congestion status information of data transmission in the first object.

[0064] In one selective embodiment of the present application, congestion in the first object includes one of the following: the QoS of the first object is not met; the data transmission rate of the first object is less than the data reception rate of the first object; there are insufficient time-frequency resources; the buffer is overflowing; and the queue is overflowing.

[0065] In one embodiment, there is a shortage of time-frequency resources; for example, the time-frequency resources of the first cell are not sufficient to transmit all the received or cached data.

[0066] In one embodiment, the first object may be a first Data Radio Bearer (DRB), and congestion in the first DRB includes one of the following: the QoS of the first DRB is not met, or the data transmission rate of the first DRB is less than the data reception rate of the first object. Failure to meet QoS means, for example, that the rate cannot be guaranteed, the packet loss rate cannot be guaranteed, the packet loss percentage cannot be guaranteed, or the PER cannot be guaranteed.

[0067] In one embodiment, the transmission rate of the first target data being less than the reception rate of the first target data includes the transmission rate of the first target data sent to the first interface being less than the transmission rate of the first target data received from the second interface. The first interface, or the second interface, includes one of the Uu interface, the N9 or N3 interface, and the N6 interface.

[0068] If the first interface is a Uu interface, the second interface may be an N3 interface. If the first interface is an N3 interface, the second interface may be a Uu interface. If the first interface is an N6 interface, the second interface may be an N3 or N9 interface. If the first interface is an N3 or N9 interface, the second interface may be an N6 interface.

[0069] In one selective embodiment of the present application, the QoS includes at least one of a guaranteed bit rate (e.g., a guaranteed flow bit rate (GFBR)), a minimum transmission rate (e.g., a minimum flow bit rate), a packet error rate (PER), a packet loss rate, a transmission delay budget, and a buffer delay budget.

[0070] Failure to satisfy the aforementioned QoS includes at least one of the following: the guaranteed flow bitrate cannot be guaranteed (e.g., the actual transmission rate is lower than the guaranteed flow bitrate); the minimum transmission rate is not satisfied (e.g., the actual minimum transmission rate is smaller than the minimum transmission rate); the packet error rate is not satisfied (e.g., the actual packet error rate is greater than the false alarm rate in QoS); the packet loss rate is not satisfied (e.g., the actual packet loss rate is greater than the false alarm rate in QoS); the transmission delay budget is not satisfied (the actual transmission delay overhead is greater than the transmission delay budget); and the buffer delay budget is not satisfied (the actual buffer delay overhead of the data is greater than the buffer delay budget).

[0071] In one selective embodiment of this application, the data packet includes a Protocol Data Unit (PDU) packet data unit.

[0072] In one selective embodiment of this application, a QoS flow having a corresponding congestion monitoring request is defined as having received and acquired a congestion monitoring request corresponding to that QoS flow. If a congestion monitoring request corresponding to that QoS flow has not been acquired, that QoS flow may be considered not to have a corresponding congestion monitoring request. The same applies to data flows having a corresponding congestion monitoring request.

[0073] In one selective embodiment of this application, data flow is an abbreviation for service data flow.

[0074] In one selective embodiment of the present application, the tunnel includes at least one of the following: a session (e.g., a PDU session, or a session between a RAN and a CN), a GTP-U, a tunnel between a RAN and a CN, a QoS flow, a QoS subflow, an Evolved Packet System (EPS) bearer, a PDP context, a DRB, a Signaling Radio Bearer (SRB), a logical channel, an IPsec-related element, or a GPRS Tunneling Protocol (GTP) tunnel. The tunnel may be instantiated as any one of the above types of tunnels.

[0075] In one embodiment of this application, the NG interface may be called the S1 interface or the N2 interface, and the naming is not limited.

[0076] The following describes the method, apparatus, and communication equipment for manipulating congestion information according to the embodiments of this application.

[0077] Referring to Figure 4, the embodiment of this application provides a flowchart of a congestion information reporting method used in a first communication device, the first communication device may be a RAN network element, and this method 400 is Step 410, which involves a first communication device obtaining first information including first request information for requesting to monitor congestion, Step 420 includes the first communication device reporting first congestion information or second congestion information based on the first information, wherein the first congestion information is information for describing a congestion situation, and the second congestion information is information for describing a data packet that requires congestion marking.

[0078] In the embodiments of this application, the first communication device includes a radio access network (RAN) device.

[0079] In the embodiments of this application, a first communication device can obtain first information from a third communication device, such as a Session Management Function (SMF).

[0080] In the embodiments of this application, the first communication device selects to report first congestion information or second congestion information based on the first information.

[0081] In the embodiments of this application, the congestion information includes, but is not limited to, the congestion level. In one embodiment, the congestion information may be represented by a percentage. For example, 0 percent represents no congestion, and the higher the percentage value, the higher the congestion level.

[0082] In one embodiment, the information of a data packet for which congestion marking is requested includes one of the percentage of data packets for which congestion marking is requested and the percentage of data packets for which congestion marking is requested. For example, if congestion occurs in a QoS flow, congestion marking may be requested for data packets in the QoS flow.

[0083] In one embodiment, there is a correspondence between congestion conditions (e.g., congestion levels) and data packets that require congestion marking. For example, the number or percentage of data packets that require congestion marking may differ depending on the different congestion conditions (e.g., congestion levels). As can be seen, the more severe the congestion (e.g., the higher the congestion level), the greater the number or percentage of data packets that require congestion marking.

[0084] In one embodiment, step 420 above may include the first communication device reporting first congestion information or second congestion information based on the first information and the second information, wherein the second information includes at least one of the capabilities of the first communication device or the local policy of the first communication device.

[0085] In one embodiment, if the first communication device has a first capability and / or does not have a second capability, the first communication device may report first congestion information.

[0086] In one embodiment, if the first communication device has a first capability and / or does not have a second capability, the first communication device may report a second congestion information.

[0087] Here, the first capability includes at least one of the following: the first communication device supporting the monitoring of congestion conditions, and the first communication device supporting the reporting of the monitored congestion conditions.

[0088] The second capability includes at least one of the following: the first communication device supports congestion monitoring (e.g., ECN for L4S) that corresponds to congestion marking; and the first communication device supports reporting information about data packets that request congestion marking.

[0089] In one embodiment, the local policy of the first communication device requires that it report either first congestion information or one of second congestion information.

[0090] For example, based on a first request information sent by the SMF to the RAN requesting that congestion be monitored (e.g., a QoS parameter requesting monitoring, and the QoS parameter requesting monitoring includes congestion information), and the RAN's local policy and / or the RAN's first capability, the RAN chooses to report information describing the congestion situation (e.g., congestion level) to the UPF, and when the UPF receives information describing the congestion situation, it discloses the congestion situation information via a service interface or N4 interface based on a second request information from the SMF requesting that congestion be monitored.

[0091] For example, based on the first request information sent by the SMF to the RAN requesting congestion monitoring (e.g., QoS parameters requesting monitoring, and these QoS parameters including congestion information), and the RAN's local configuration and / or second capability, the RAN chooses to report to the UPF information for describing data packets requesting congestion marking. The UPF then selects data packets with corresponding percentages in the congestion direction and sets congestion marking (e.g., Control Element (CE)) based on the received information for describing data packets requesting congestion marking and the second request information sent by the SMF requesting congestion monitoring.

[0092] In one embodiment, the first request information is: Information for requiring monitoring of a first congestion, wherein the purpose of monitoring the first congestion includes disclosing congestion information, Information for requesting monitoring of a second congestion, wherein the use of monitoring the second congestion includes information that includes congestion marking of data packets.

[0093] In one embodiment, step 420 described above is: The first communication device reports the first congestion information when the first information includes information instructing the monitoring of the first congestion, The first communication device may report the second congestion information if the first information includes information instructing the monitoring of the second congestion.

[0094] In the embodiments of this application, when the first communication device obtains information to request monitoring of a first congestion, the first communication device reports the first congestion information, and when the first communication device obtains information to request monitoring of a second congestion, the first communication device reports the second congestion information, and the reporting method is to perform congestion marking on data packets.

[0095] In one embodiment, the first request information, for example, the requested QoS parameters, includes at least one of a first congestion and a second congestion. For example, the first congestion may be used to disclose congestion information via an N4 interface or a UPF service interface. The second congestion is used to perform congestion marking on data packets, for example, congestion for ECN marking for L4S.

[0096] In one embodiment, the first information further includes a third information, and the third information is Information on congestion status, It is used to request that one of the data packets' pieces of information be reported, which may require congestion marking.

[0097] In one embodiment, step 420 described above is: (1) When the third information includes information requesting a report of congestion status, the first communication device reports the first congestion information, (2) The first communication device may report the second congestion information if the third information includes information that requires reporting of data packets that require congestion marking.

[0098] In the above embodiment, the first communication device acquires the third information in the first information to obtain the type of reported congestion information as information requesting a report of congestion status or information requesting a report of data packets that require congestion marking, and based on this third information in the first information, reports congestion information corresponding to the type of congestion information indicated by the third information in the first information.

[0099] Referring to Figure 5, the embodiment of the present application further provides a flowchart of a method for reporting congestion information used in a first communication device, the first communication device may be a RAN network element, and this method 500 may include the following steps.

[0100] In step 510, the first communication device obtains first information including first request information for requesting to monitor congestion, In step 520, the first communication device reports a third congestion information, which is percentage information corresponding to the congestion information, based on the first information.

[0101] The difference between Method 500 and Method 400 is that in Method 500, the first communication device does not distinguish whether the reported third congestion information is information for describing a congestion situation or information for describing a data packet that requires congestion marking. The second communication device may understand the third congestion information reported by the first communication device as the first or second congestion information based on at least one of the following: second request information for requesting monitoring of congestion transmitted by the third communication device, information for requesting disclosure of congestion information, and information for requesting that a congestion marking operation be performed on a data packet.

[0102] In one embodiment, the percentage information corresponding to the congestion information may be used to represent at least one of the following: the congestion status and the percentage of all data packets that require congestion marking.

[0103] In one embodiment, the percentage information corresponding to congestion information indicates that it is used to describe the congestion situation and represents the percentage of all data packets that require congestion marking.

[0104] In the embodiments of this application, the first communication device may include a RAN device.

[0105] In the embodiments of this application, the first communication device can obtain the first information from the third communication device, for example, from a Session Management Function (SMF).

[0106] In one embodiment, there is a correspondence between congestion conditions (e.g., congestion levels) and data packets that require congestion marking. For example, the number or percentage of data packets that require congestion marking may differ depending on the different congestion conditions (e.g., congestion levels). As can be seen, the more severe the congestion (e.g., the higher the congestion level), the greater the number or percentage of data packets that require congestion marking.

[0107] Therefore, the same percentage may represent the congestion status, or the percentage of data packets that require congestion marking. For example, a percentage value of 0 percent may represent either no congestion or zero percentage of data packets that require congestion marking (i.e., no data packets are required to be congestion marked). A higher percentage value represents either a more severe congestion situation (e.g., a high congestion level) or a higher percentage of data packets that require congestion marking.

[0108] In the embodiments of this application, the first communication device can obtain first information from the third communication device, where the third communication device may be a Session Management Function (SMF).

[0109] According to the embodiment of this application, the first communication device acquires first information including first request information, and based on this first information, reports either first congestion information or second congestion information, thereby determining the type of congestion information to report.

[0110] Referring to Figure 6, an embodiment of the present application provides a flowchart of a method for manipulating congestion information used in a second communication device, the second communication device may include a CN network element. The CN network element includes a UPF (e.g., PSAUPF), and this method 600 corresponds to the above method 400, and as shown in Figure 6, the above method 600 may include the following steps.

[0111] In step 610, the second communication device receives either the first congestion information or the second congestion information, wherein the first congestion information is information for describing the congestion situation, and the second congestion information is information for describing a data packet that requests congestion marking. In step 620, the second communication device is: Disclosing the first congestion information, or performing congestion marking on data packets based on the second congestion information, At least one of the following is performed: ignoring the first congestion information received, or ignoring the second congestion information received.

[0112] In the embodiments of this application, the second communication device includes a User Plane Function (UPF) device.

[0113] In the embodiments of this application, the second communication device can receive either first or second congestion information from the first communication device, for example, from the RAN. In a specific application, the first communication device may transmit either first or second congestion information using the above method, and can refer specifically to the description in the embodiment of the method shown in Figure 4.

[0114] In one embodiment, the information of a data packet for which congestion marking is requested includes one of the percentage of data packets for which congestion marking is requested and the percentage of data packets for which congestion marking is requested. For example, if congestion occurs in a QoS flow, congestion marking may be requested for data packets in the QoS flow.

[0115] In one embodiment, ignoring the first congestion information received by the second communication device is: If the first condition is met, the second communication device may include ignoring the received first congestion information, where the first condition is: The second communication device mentioned above has not acquired the information necessary to request the disclosure of congestion information, This includes at least one of the following: the second communication device obtains information for requesting that a congestion marking operation be performed on a data packet.

[0116] In the embodiments of this application, if a second communication device receives first congestion information, i.e., information describing a congestion situation, but does not acquire information to request disclosure of the congestion information, the second communication device ignores the received first congestion information and, for example, does not disclose the first congestion information. Alternatively, if a second communication device receives first congestion information, i.e., information describing a congestion situation, but acquires further information to request that a congestion marking operation be performed on data packets, the second communication device ignores the received first congestion information and, for example, does not disclose the first congestion information.

[0117] In one embodiment, the second communication device can obtain from the third communication device information for requesting the disclosure of congestion information or information for requesting that a congestion marking operation be performed on the data packets.

[0118] For example, if a second communication device receives first congestion information transmitted by a first communication device, but at the same time, a third communication device has not instructed the second communication device to disclose the congestion information, or the second communication device has not instructed the second communication device to perform a congestion marking operation on the data packets, i.e., the third communication device has not sent information to the second communication device to request the disclosure of congestion information, or has not sent information to the second communication device to request the performance of a congestion marking operation on the data packets, then the second communication device will ignore the first congestion information it received because it is not required to disclose the congestion information.

[0119] In one embodiment, ignoring the second congestion information received by the second communication device is: If the second condition is met, the second communication device may include ignoring the received second congestion information, where the second condition is: The second communication device has not obtained the information necessary to request that a congestion marking operation be performed on the data packet, This includes at least one of the following: the second communication device obtains information for requesting the disclosure of congestion information.

[0120] In the embodiments of this application, if a second communication device receives second congestion information, i.e., information for describing a data packet that requires congestion marking, but does not obtain information for requesting that a congestion marking operation be performed on the data packet, the second communication device ignores the received second congestion information and, for example, does not perform congestion marking on the data packet based on the second congestion information. Alternatively, if a second communication device receives second congestion information, i.e., information for describing a data packet that requires congestion marking, but the second communication device obtains further information for requesting disclosure of congestion information, the second communication device ignores the received second congestion information.

[0121] In one embodiment, a second communication device can obtain from a third communication device information for requesting that a congestion marking operation be performed on the data packets, or information for requesting that the congestion information be disclosed.

[0122] For example, if a second communication device receives second congestion information transmitted by a first communication device, but at the same time, a third communication device has not instructed the second communication device to perform a congestion marking operation on the data packets or to disclose the congestion information, that is, the third communication device has not sent information to the second communication device requesting it to perform a congestion marking operation on the data packets or to disclose the congestion information, then the second communication device will not be required to perform a congestion marking operation on the data packets and will therefore ignore the received second congestion information.

[0123] In one embodiment, the first or second condition further includes obtaining second request information to request the second communication device to monitor congestion.

[0124] In one embodiment, the second communication device can obtain second request information from a third communication device (e.g., SMF).

[0125] Here, the second request information for requesting congestion monitoring includes, but is not limited to, the QoS parameters to be monitored, and the QoS parameters to be monitored include congestion.

[0126] Referring to Figure 7, an embodiment of the present application provides a flowchart of another method for manipulating congestion information used in a second communication device, the second communication device may be a User Plane Function (UPF) network element, and this method 700 corresponds to the above method 500, and as shown in Figure 7, this method 700 may include the following steps.

[0127] In step 710, the second communication device receives third congestion information, which is percentage information corresponding to the congestion information. In step 720, the second communication device understands the third congestion information as either information describing the congestion situation or the percentage of all data packets that require congestion marking.

[0128] In the embodiments of this application, the second communication device includes a User Plane Function (UPF) device.

[0129] In the embodiments of this application, the second communication device may receive third congestion information from the first communication device, for example, from the RAN.

[0133] In one embodiment, the second communication device understands the third congestion information as information for describing the congestion situation. If the third condition is met, the second communication device understands the third congestion information as information for describing the congestion situation, Here, the third condition includes obtaining a second request information for the second communication device to request that it monitor congestion.

[0134] In one embodiment, the second communication device can obtain second request information from a third communication device (e.g., SMF).

If the fourth condition is met, the second communication device includes determining the second congestion information based on the third congestion information, wherein the fourth condition includes obtaining information for requesting the second communication device to perform a congestion marking operation on a data packet.

[0137] In one embodiment, the second communication device can obtain information from a third communication device (e.g., SMF) to request that it perform the congestion marking operation on the data packets.

[0139] In the embodiments of this application, the second communication device receives either first or second congestion information reported by the first communication device, the first congestion information is used to describe information about the congestion situation, and the second congestion information is used to describe information about data packets that require congestion marking, thereby enabling the second communication device to determine a corresponding processing operation based on the received congestion information.

[0140] Alternatively, a second communication device may receive third congestion information and understand that data packets requesting information to describe the congestion situation or congestion marking represent a percentage of all data packets, and may perform operations corresponding to this congestion information.

[0144] The first request information includes monitoring congestion in the RAN and / or air interface. The second request information includes monitoring congestion information reported by the user plane tunnel. For example, the first communication device monitors congestion in the first QoS flow and reports the corresponding congestion information via the user plane tunnel (for example, by being carried in the header of the user plane tunnel's data packets).

[0168] In one embodiment, the fourth communication device obtains a request to perform a congestion marking operation on a data packet by at least one of AF, NEF, and TSCTSF.

[0169] In one embodiment, the seventh piece of information is included in a first policy (e.g., PCCrule) and transmitted. The first policy is a policy corresponding to the first data flow.

[0170] In the following, we will describe the technical proposal according to the embodiment of this application using a specific application scenario, taking as an example that the first communication device is a RAN, the second is a UPF, the third is an SMF, and the fourth is a PCF.

[0171] Figure 10 shows a flowchart of the method for handling congestion information in an embodiment of the present application. In the flow shown in Figure 10, the RAN reports the third congestion information, and the UPF understands the third congestion information as information for describing the congestion situation (i.e., the first congestion information) based on the second request information transmitted by the SMF requesting that congestion be monitored.

[0172] As shown in Figure 10, this method mainly involves the following steps: In step 1001, AF orders congestion information to PCF, Here, the PCF has received a request to perform a congestion marking operation on the data packets of the first data flow (i.e., the ECN marking operation for L4S mentioned above), and in order to satisfy the eighth condition above, the PCF sends the fifth information to the SMF according to the solution described in the embodiment shown in Figure 9. Therefore, the fifth information is, Information to request monitoring of congestion, Information to request monitoring of congestion, The aforementioned use for monitoring congestion, including disclosing congestion information, Information for requiring monitoring of a first congestion, wherein the purpose of monitoring the first congestion includes disclosing congestion information, This may include at least one of the following: a third piece of information requesting the reporting of information on congestion status, Here, Information for requesting congestion monitoring may be embodied as QoS parameters requesting monitoring, and these QoS parameters requesting monitoring include congestion.

[0173] In step 1002, the PCF sends Policy Control and Charging (PCC) rules to the SMF, and optionally, the PCC rules include fifth information.

[0174] The fifth piece of information mentioned above is, Information to request monitoring of congestion, Information to request monitoring of congestion, The aforementioned use for monitoring congestion, including disclosing congestion information, Information for requiring monitoring of a first congestion, wherein the purpose of monitoring the first congestion includes disclosing congestion information, This may include at least one of the following: a third piece of information requesting the reporting of information on congestion status, The fifth piece of information includes information for monitoring congestion. Here, a request for monitoring congestion may be embodied as a QoS parameter requesting monitoring, and the QoS parameter requesting monitoring includes congestion information.

[0175] Here, the SMF may perform a third operation based on a fifth piece of information (for example, information requesting to monitor congestion), and specifically, the SMF may perform the third operation by employing the third communication equipment configuration described in the embodiment of the method shown in Figure 8.

[0176] In step 1003, the SMF sends a first request information to the RAN requesting that congestion be monitored, the first request information being as shown in the embodiment of Figure 8 (corresponding to Option 1). The aforementioned use of congestion monitoring includes at least one of disclosing congestion information and performing congestion marking operations on data packets.

[0177] For example, the first request information may be embodied as a QoS parameter that requests monitoring, and the QoS parameter that requests monitoring includes congestion. The aforementioned use of monitoring congestion includes disclosing congestion information and performing congestion marking operations on data packets.

[0178] In step 1004, the SMF sends a second request to the CN UP (UPF) requesting it to monitor congestion, the second request being as shown in the embodiment of Figure 5 (corresponding to Option 2 / 3). Exemplarily, the first request may be embodied as a QoS parameter to be monitored, the QoS parameter to be monitored including congestion.

[0179] Selectively, the SMF may send an N4 message to the UPF containing QoS parameters requesting monitoring, where the QoS parameters requesting monitoring include congestion information.

[0180] In step 1005, the RAN performs congestion monitoring based on the first request information. In step 1006, based on the first request information sent by the SMF to request monitoring of congestion, the RAN reports percentage information corresponding to the congestion information (i.e., third congestion information) to the CN UP (UPF), In step 1007, CN UP (UPF) understands the third congestion information as information to describe the congestion situation, based on the second request information for requesting to monitor the acquired congestion. Selectively, CN UP (UPF) discloses the information to describe the congestion situation via a service interface or an N4 interface.

[0181] Figure 11 shows another flowchart of the method for handling congestion information in an embodiment of the present application, in the flow shown in Figure 11, where the RAN reports third congestion information, and the UPF understands the third congestion information as the percentage of all data packets for which congestion marking is requested (i.e., second congestion information), based on the information transmitted by the SMF for requesting that congestion marking operations be performed on data packets.

[0182] As shown in Figure 11, this method mainly involves the following steps: In step 1101, AF requests PCF to perform an ECN marking operation for L4S, Here, the PCF has received a request to perform a congestion marking operation on the data packets of the first data flow (i.e., the ECN marking operation for L4S mentioned above), and in order to satisfy the ninth condition above, the PCF sends the fifth piece of information to the SMF according to the solution described in the embodiment shown in Figure 9. Therefore, the fifth piece of information is, Information to request monitoring of congestion, Information to request monitoring of congestion, The aforementioned use for monitoring congestion, including disclosing congestion information, Information for requiring monitoring of a first congestion, which may include at least one of the above-mentioned information for which the purpose of monitoring the first congestion includes disclosing congestion information, In step 1102, the PCF sends Policy Control and Charging (PCC) rules to the SMF. Selectively, the PCC rules include fifth information.

[0183] The fifth piece of information includes information for monitoring congestion. Here, a request for monitoring congestion may be embodied as a QoS parameter requesting monitoring, and the QoS parameter requesting monitoring includes congestion information.

[0184] Here, the SMF may perform a third operation based on a fifth piece of information (for example, information requesting to monitor congestion), and specifically, the SMF may perform the third operation by employing the third communication equipment configuration described in the embodiment of the method shown in Figure 8.

[0185] In step 1103, the SMF sends a first request information to the RAN requesting that congestion be monitored, the first request information being as shown in the embodiment of Figure 8 (corresponding to Option 1). The aforementioned use of congestion monitoring includes at least one of disclosing congestion information and performing congestion marking operations on data packets.

[0186] For example, the first request information may be embodied as a QoS parameter that requests monitoring, and the QoS parameter that requests monitoring includes congestion. The aforementioned use of monitoring congestion includes disclosing congestion information and performing congestion marking operations on data packets.

[0187] In this embodiment, the sixth condition described above is met, and the SMF sends information to the UPF requesting that a congestion marking operation be performed on the data packets. The information requesting that a congestion marking operation be performed on the data packets may be embodied as an ECN marking operation for L4S.

[0188] In step 1104, the SMF sends information to the CN UP (UPF) requesting that a congestion marking operation be performed on the data packets. In step 1105, the RAN performs congestion monitoring. In step 1106, based on the first request information sent by the SMF to request monitoring of congestion, the RAN sends percentage information corresponding to the congestion information (i.e., third congestion information) to the CN UP (UPF), In step 1107, CN UP (UPF) interprets the third congestion information as information describing the data packets for which congestion marking is requested (i.e., second congestion information), based on the information transmitted by SMF requesting that congestion marking operations be performed on the data packets, and selects the data packets corresponding to the congestion direction and performs congestion marking.

[0189] According to the above-described technical invention in the embodiment of this application, the UPF can determine whether the third congestion information reported by the RAN is information describing the congestion situation or information describing the data packet for which congestion marking is requested, based on the second request information transmitted by the SMF for requesting to monitor congestion or for requesting to perform a congestion marking operation on a data packet, and then perform the corresponding operation on the received congestion information.

[0190] Figure 12 shows another flowchart of the method for handling congestion information in an embodiment of the present application, in the flow shown in Figure 12, where the RAN reports first congestion information based on local policies and / or the capabilities of the RAN, the UPF receives the first congestion information and discloses information describing the congestion situation.

[0191] As shown in Figure 12, this method mainly involves the following steps: In step 1201, AF orders congestion information to PCF, In step 1202, the PCF sends Policy Control and Charging (PCC) rules to the SMF, which is the same as step 1002 in Figure 10 above, and specifically refers to the description of step 1002 above.

[0192] Here, the SMF may perform a third operation based on the PCC rules, and specifically, the SMF may perform the third operation by employing the third communication equipment configuration described in the embodiment of the method shown in Figure 8.
