Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to Chinese Patent Application No. 202211139954.1, filed in China on September 19, 2022, the entire contents of which are incorporated herein by reference.

[0002] FIELD OF THE INVENTION The present invention relates to the technical field of wireless communication, and more particularly to an information processing method and a communication device. [Background technology]

[0003] An external application or terminal can subscribe to congestion status information of a specific service data stream in a 5th generation (5G) communication system (5GS). 5GS congestion mainly occurs on the air interface, and in related technologies, congestion monitoring is mainly reported by a Radio Access Network (RAN). User Equipment (UE) may also monitor uplink congestion.

[0004] In the related art, when a terminal is switched from a source RAN to a target RAN, the congestion situations may be different between the source RAN and the target RAN. If the terminal is not congested in the target RAN, the target RAN network element may not operate. If the server or client does not recognize that the serving RAN network element has already changed, it may determine that the congestion is still ongoing.

[0005] From the above, it can be seen that the congestion status information in the related art has a problem of not being updated in a timely manner, which reduces the throughput of the service data stream. Summary of the Invention [Problem to be solved by the invention]

The techniques described herein may be used with other systems and radio technologies in addition to those mentioned above.

[0025] In order to make the embodiments of the present invention easier to understand, the following technical points will be first explained below.

[0026] There are several methods for reporting congestion in the related art:

[0027] Method 1: The RAN marks data packets with Explicit Congestion Notification (ECN) / Low Latency, Low Loss, Scalable Throughput (L4S).

[0028] Method 2: The RAN reports congestion information to a user plane network element (e.g., a User Plane Function (UPF)) in a Core Network (CN), and the UPF performs ECN / L4S marking.

[0029] Method 3: The RAN reports congestion information to a CN user plane network element (e.g., UPF), the UPF reports the congestion information to a CN control plane network element (e.g., one of an Access Management Function (AMF), a Session Management Function (SMF), or a Policy Control Function (PCF)), and the CN network element (e.g., one of a Network Exposure Function (NEF), or a PCF) discloses the congestion status information.

[0030] Method 4: The RAN reports congestion information to a CN control plane network element (e.g., one of AMF, SMF, or PCF), and the CN (e.g., one of NEF or PCF) discloses the congestion status information.

[0031] Currently, there is a need to solve the following problems:

[0032] Situation 1: When a terminal is switched from a source RAN to a target RAN, if the source RAN has congestion in a first target and has reported a first congestion level or the start of congestion in the first target, when the terminal is switched to the target RAN, the congestion or first congestion level in the first target may disappear, but the target RAN does not recognize that the source RAN has previously reported congestion information for the first target and does not report congestion-related information for the first target, so the server or client determines that the congestion in the first target is still ongoing.

[0033] Scenario 2: The UE's connection to the RAN may experience a radio link failure, so when the RRC is re-established to the new RAN, the new RAN may not be able to obtain the UE context (including the latest congestion information, congestion level, etc.) of the UE in the previous RAN.

[0034] As a solution, when a congestion reporting condition is met (e.g., congestion begins or a congestion level is reached), the RAN network element continuously causes uplink data packets to carry congestion information. Until the congestion reporting condition is no longer met (e.g., congestion ends), the RAN causes uplink data packets to carry congestion information, implicitly indicating the end of congestion. In this way, if the terminal moves to another RAN, there is no action because there is no congestion in the QoS flow, which is equivalent to implicitly indicating the end of congestion or that congestion has disappeared.

[0035] However, the following problems still need to be solved:

[0036] Problem 1: When downlink congestion occurs, there may be no uplink data packets. At this time, how to report uplink congestion information still needs to be solved.

[0037] Problem 2: Because "the occurrence of a transition from a state where the congestion reporting condition is satisfied to a state where the congestion reporting condition is not satisfied" is critical, in addition to the final time of congestion, the start time when congestion disappears can also be expressed. At this time, it is not yet clear whether to report congestion information, or not report congestion information and implicitly indicate that there is no congestion, or explicitly report that there is no congestion, and this needs to be resolved.

[0038] The same applies to "occurrence of a transition from a state in which the congestion reporting condition is not satisfied to a state in which the congestion reporting condition is satisfied."

[0039] Problem 2: When congestion occurs in the first communication device in the QoS flow of the UE, the UE is switched from the first communication device to another communication device, and then moves away from the first communication device, it is not clear whether the first communication device will report the congestion information last, which needs to be resolved.

In one embodiment, when the congestion information includes a clear indication of congestion direction, the congestion information is congestion information indicating a specific direction; for example, when the congestion information includes information for indicating the start of congestion or the occurrence of congestion and information for indicating a congestion direction, if the information for indicating the congestion direction indicates downlink, the congestion information is downlink congestion information; for example, when the congestion information includes information for indicating the start of downlink congestion or the occurrence of downlink congestion, the congestion information is downlink congestion information; for example, when the congestion information includes information for indicating the start of downlink congestion or the occurrence of downlink congestion and information for indicating the start of uplink congestion or the occurrence of uplink congestion, the congestion information is uplink / downlink congestion information.

[0176] The transition from a non-congested state to a congested state is the critical point between the non-congested and congested states, and can represent the start time of congestion as well as the final time of congestion.

[0177] In one embodiment, if a congestion reporting condition is met includes a transition from a congested state to a non-congested state, then a congestion reporting condition is not met does not include a transition from a congested state to a non-congested state, or vice versa.

[0180] In one embodiment, if a congestion reporting condition is met includes a first object being released at the first communication device, then a congestion reporting condition is not met does not include a first object being released at the first communication device, and vice versa.

[0185] The congestion ending means that the congestion of the first target ends.

[0186] The end of congestion or absence of congestion includes a period of time in which congestion ends or there is no congestion.

[0187] In one embodiment, when the first communication device is a terminal, the terminal determines that the congestion reporting condition is not met when it determines that it has moved away from the access network device that it currently accesses or has migrated from the access network device that it currently accesses (the access network device can be considered as the source access network device), and when the first communication device is a RAN, the RAN determines that the congestion reporting condition is not met when it recognizes the presence of the terminal's migration or moving away.

[0189] When the first communication device is a RAN network element, when it receives an uplink data packet of a first QoS flow, the uplink data packet of the first QoS flow is transmitted by the terminal to the RAN network element.

[0190] According to an embodiment of the present invention, in one aspect, when a QoS flow of a terminal is congested in the RAN, the RAN continuously reports congestion information in each uplink packet of the QoS flow during the congestion period to realize an explicit indication of congestion, and when the congestion ends, stops sending all congestion marks to implicitly indicate the end of the congestion, thereby updating the congestion status in real time. Therefore, even if the RAN network element is changed, a core network element, server, or client can timely obtain the congestion status and guarantee the throughput of the service data stream. In another aspect, during a period without congestion, the RAN continuously reports no-congestion information in each uplink packet of the QoS flow to realize an explicit no-congestion indication. Furthermore, the embodiment of the present invention clearly limits how information is reported at a critical time when a transition occurs from a state in which the congestion reporting condition is met to a state in which the congestion reporting condition is not met, thereby ensuring an accurate indication of the congestion status.

[0230] The downlink data packets received by the second communication device are those sent from the server to the second communication device.

[0231] According to an embodiment of the present invention, when a QoS flow of a terminal is congested in the RAN, the RAN continuously reports congestion information in each uplink packet of the QoS flow during the congestion period to realize an explicit indication of the congestion, and when the congestion ends, stops sending all congestion marks to implicitly indicate the end of the congestion, thereby updating the congestion status in real time. Therefore, even if the RAN network element is changed, the CN can timely obtain the congestion status and disclose it to the server or client, and the server or client can timely obtain the congestion status and ensure the throughput of the service data stream. Furthermore, the embodiment of the present invention clearly defines how to report information at a critical time when a transition occurs from a state in which the congestion reporting condition is met to a state in which the congestion reporting condition is not met, thereby ensuring an accurate indication of the congestion status.

[0232] In the following, the transmission status of uplink data packets in different cases according to the embodiment of the present invention will be described by taking examples as follows:

[0233] Case 1 As shown in FIG. 4, the first communication device reports congestion information via each uplink data packet of the first QoS flow within a first period, the first period being the period between a first start time and a first end time.

[0234] Case 2 As shown in FIG. 5a, if there is no uplink data packet of the first QoS flow within the first period, the first communication device generates a first dummy data packet carrying congestion information at a first start time and generates a first dummy data packet carrying congestion information at a first end time.

[0235] 5b, if there are no uplink data packets of the first QoS flow within the first time period, the first communication device generates a first dummy data packet carrying congestion information at a first start time and generates a second dummy data packet carrying no congestion information or the first status information at a first end time. Not carrying the first status information indicates that the second dummy data packet may not carry any congestion status information (e.g., not carrying the first bit or setting the first bit to 0).

[0236] As shown in FIG. 5c, if there are no uplink data packets of the first QoS flow within the first period, the first communication device generates a first dummy data packet carrying congestion information at a first start time and a second dummy data packet carrying the first information at a first end time.

[0237] Case 3 6a, if there is no uplink data packet of the first QoS flow at a first start time, the first communication device generates a first dummy data packet carrying congestion information and transmits the first dummy data packet at a time after the first start time.If there is no uplink data packet of the first QoS flow at a first end time, the first communication device generates a first dummy data packet carrying congestion information and transmits the first dummy data packet at a time after the first end time.

[0238] It should be noted here that the first start time is the time when the congestion reporting condition is met or congestion occurs, and the first end time is the time when the congestion reporting condition is no longer met or congestion ends.

[0239] In one embodiment, the time interval between a time after a target time (eg, a first start time, a first end time) and the target time may be the processing time.

[0240] The processing time is sufficient to perform the first, second, third or fourth operation, for example, sufficient to cause uplink data packets of the first QoS flow to carry congestion information or the first information, and sufficient to configure dummy data packets to carry the congestion information or the first information.

[0241] As shown in Figure 6b, the operation of the first start time is the same as that of Figure 6a, and detailed description is omitted here. The difference is that if there is no uplink data packet of the first QoS flow at the first end time, the first communication device generates a second dummy data packet that does not carry congestion information or first status information, and transmits the second dummy data packet at a time after the first end time.

[0242] As shown in Figure 6c, the operation of the first start time is the same as that of Figure 6a, and detailed description is omitted here. The difference is that if there is no uplink data packet of the first QoS flow at the first end time, the first communication device generates a second dummy data packet carrying the first information and transmits the second dummy data packet at a time after the first end time.

[0243] Case 4 7a, when there is no uplink data packet of the first QoS flow within a first time interval, the first communication device generates a first dummy data packet carrying congestion information and transmits the first dummy data packet.When there is no uplink data packet of the first QoS flow within a second time interval, the first communication device generates a first dummy data packet carrying congestion information and transmits the first dummy data packet.

[0244] What should be explained here is that the first time interval is a time interval that starts from a first start time, and the second time interval is a time interval that starts from a first end time.

[0245] As shown in Figure 7b, the operation of the first start time is the same as that of Figure 7a, and detailed description thereof will be omitted here. The difference is that if there is no uplink data packet of the first QoS flow within the second time interval, the first communication device generates a second dummy data packet that does not carry congestion information or first status information, and transmits the second dummy data packet.

[0246] As shown in Figure 7c, the operation of the first start time is the same as that of Figure 7a, and a detailed description thereof will be omitted here. The difference is that if there is no uplink data packet of the first QoS flow within the second time interval, the first communication device generates a second dummy data packet carrying the first information and transmits the second dummy data packet.

[0247] Case 5 As shown in FIG. 8a, if there is no uplink data packet of the first QoS flow at the first start time, the first communication device starts a first timer, generates a first dummy data packet carrying congestion information when the first timer times out, and simultaneously restarts the first timer, and then repeats the above process again. When an uplink data packet of the first QoS flow is received at a certain time, the first communication device stops timing the first timer and reports the congestion information via the uplink data packet of the first QoS flow, and then restarts the first timer, generates a first dummy data packet carrying congestion information when the first timer times out, and simultaneously restarts the first timer, and then repeats the above process again. When a first end time is reached, the first communication device generates a first dummy data packet carrying congestion information, and simultaneously stops the first timer.

[0248] As shown in Figure 8b, the operation of the first start time is the same as that of Figure 8a, and detailed description is omitted here. The difference is that when the first end time is reached, a second dummy data packet that does not carry congestion information or first status information is generated, and the first timer is stopped at the same time. The first communication device transmits the second dummy data packet.

[0249] As shown in Figure 8c, the operation of the first start time is the same as that of Figure 8a, and a detailed description thereof will be omitted here. The difference is that when the first end time is reached, a second dummy data packet carrying the first information is generated and the first timer is stopped. The first communication device transmits the second dummy data packet.

[0250] Case 6 As shown in FIG. 9, if there is no uplink data packet of the first QoS flow at the first start time, the first communication device starts a first timer and generates a first dummy data packet carrying congestion information when the first timer times out.

[0251] Optionally, if there are no uplink data packets of the first QoS flow when the first end time is reached, the first communication device starts a second timer, and when the second timer times out, in one embodiment, generates a first dummy data packet carrying congestion information; in another embodiment, generates a second dummy data packet that does not carry congestion information or the first status information; and in another embodiment, generates a second dummy data packet carrying the second information when the first end time is reached.

[0252] Optionally, when the first end time is reached, a first dummy data packet is generated.

[0253] Case 7 As shown in FIG. 10a, if there is no uplink data packet of the first QoS flow at the first end time, the first communication device starts a second timer, generates a second dummy data packet carrying the first information when the second timer times out, and simultaneously restarts the second timer. When an uplink data packet of the first QoS flow is received at a certain time, the first communication device stops timing the second timer and reports the first information through the uplink data packet of the first QoS flow. Then, the first communication device restarts the second timer, generates a second dummy data packet carrying the first information when the second timer times out, and simultaneously restarts the second timer. Then, the above process is repeated again. When the second start time is reached, the first communication device generates a first dummy data packet carrying congestion information, and simultaneously stops the second timer.

[0254] As shown in Figure 10b, if there is no uplink data packet of the first QoS flow at the first end time, the first communication device starts a second timer, generates a second dummy data packet that does not carry congestion information or the first status information when the second timer times out, and simultaneously restarts the second timer. When an uplink data packet of the first QoS flow that does not carry congestion information or the first status information is received at a certain time, the first communication device stops timing the second timer, then restarts the second timer, generates a second dummy data packet that does not carry congestion information when the second timer times out, and simultaneously restarts the second timer. Then, the above process is repeated again, and when the second start time is reached, the first dummy data packet that carries congestion information is generated, and simultaneously stops the second timer.

[0255] Case 8 As shown in FIG. 11a, if there is no uplink data packet of the first QoS flow at the first end time, the first communication device starts a second timer, generates a second dummy data packet carrying the first information when the second timer times out, and generates a first dummy data packet carrying the congestion information when the second start time is reached.

[0256] As shown in FIG. 11b, if there is no uplink data packet of the first QoS flow at the first end time, the first communication device starts a second timer, generates a second dummy data packet that does not carry congestion information or first status information when the second timer times out, and generates a first dummy data packet that carries congestion information when the second start time is reached.

[0257] Application scenario 1 of the embodiment of the present invention mainly describes the uplink congestion handling process, which refers to Figure 12 and includes the following steps S11 to S19.

[0258] In step S11, the PCF sends a congestion monitoring request, which may include an uplink congestion monitoring request, to the SMF.

[0259] Alternatively, the congestion monitoring request may be conveyed to a PCC rule.

[0260] In step S12, the SMF sends a congestion monitoring request corresponding to the QoS flow to the RAN (abbreviation for RAN network element).

[0261] In step S13, congestion occurs. To transmit congestion information, there are four options: 1) steps S14 to S15, 2) steps S16 to S17, 3) step S18, and 4) step S19.

[0262] In step S14, the RAN transmits the uplink data packets of the first QoS flow.

[0263] The uplink data packet carries congestion information including information for indicating the start of congestion, information for indicating a congestion level, and information for indicating a congestion direction (the congestion direction in this case is uplink); Note that in step S14, the RAN continuously carries congestion information via uplink data packets of different first QoS flows.

[0264] In step S15, after receiving the uplink data packet from the RAN, the UPF changes the ECN mark in the uplink data packet to a value to indicate the occurrence of congestion (i.e., changes the ECN mark to CE), and transmits the uplink data packet to the server.

[0265] Note that step S15 corresponds to step S14, that is, the UPF performs the operation of changing the ECN mark every time it receives an uplink data packet.

[0266] In step S16, the RAN transmits the uplink data packets of the first QoS flow.

[0267] The uplink data packet carries congestion information including information for indicating the onset of congestion, information for indicating a congestion level, and information for indicating a congestion direction; Note that in step S16, the RAN continuously carries congestion information via uplink data packets of different first QoS flows.

[0268] In step S17, after receiving the uplink data packet from the RAN, the UPF sends the second information to the SMF via N4 interface signaling, or the UPF directly publishes the second information to other NFs (e.g., SMF, PCF, NEF, AF) via the service interface.

[0269] The second information is transmitted via N4 interface signaling, and includes information for indicating the start of congestion and information for indicating the congestion direction.

[0270] Note that step S16 corresponds to step S17, and normally, the UPF only performs the operation of sending the second information when it first receives the first data packet. If the congestion state has not changed, step S17 is not performed, i.e., the UPF does not send the second information.

[0271] That is, in such an application scenario, during a period in which uplink congestion occurs, the RAN continuously adds congestion information to each uplink data packet of the first QoS flow, and the UPF also changes the ECN mark of the corresponding uplink data packet to CE. Also, in such an application scenario, during a period in which uplink congestion occurs, the RAN continuously adds congestion information to each uplink data packet of the first QoS flow, but the UPF reports the congestion information only once via N4 signaling, not multiple times.

[0272] When the congestion ends, the RAN stops adding congestion information to each uplink data packet of the first QoS flow. When congestion information is no longer received, the UPF can remove the congestion status of the first QoS flow and signal the end of the congestion via N4 signaling or stop changing the ECN mark, i.e., implicitly signal the end of the congestion.

[0273] In step S18, when the congestion information (mainly uplink congestion information in this case) is transmitted to the PCF via control plane signaling, the congestion information may be transmitted by the RAN to the AMF, forwarded by the AMF to the SMF, and further forwarded by the SMF to the PCF; For example, congestion information is transmitted via N4 interface messages.

[0274] In step S19, when congestion information (in this case, mainly uplink congestion information) is transmitted to the UPF via control plane signaling, it may be sent to the AMF by the RAN, forwarded to the SMF by the AMF, and further forwarded to the UPF by the SMF.

[0275] Application scenario 2 of the embodiment of the present invention Application scenario 2 of the embodiment of the present invention mainly describes the downlink congestion handling process, which refers to Figure 13 and includes the following steps S21 to S31.

[0276] In step S21, the PCF sends a congestion monitoring request, which may include a downlink congestion monitoring request, to the SMF.

[0277] Alternatively, the congestion monitoring request may be conveyed to a PCC rule.

[0278] In step S22, the SMF sends a congestion monitoring request corresponding to the QoS flow to the RAN (abbreviation for RAN network element).

[0279] In step S23, downlink congestion occurs. There are four options for transmitting congestion information: 1) steps S24 to S28, 2) step S29, 3) step S30, and 4) step S31.

[0280] In step S24, the RAN transmits the uplink data packets of the first QoS flow.

[0281] The uplink data packet carries congestion information including information for indicating the start of congestion and information for indicating the congestion direction (in this case, the congestion direction is downlink); Note that in step S24, the RAN continuously carries congestion information via uplink data packets of different first QoS flows.

[0282] In step S25, the first downlink data packet sent from the server is received.

[0283] In step S26, the ECN mark in the first downlink data packet received from the server is changed to a value indicating the occurrence of congestion (that is, the ECN mark is changed to CE).

[0284] In step S27, the first downlink data packet with the modified ECN mark is sent to the RAN.

[0285] In step S28, the RAN transmits another uplink data packet of the first QoS flow.

[0286] The uplink data packet carries congestion information including information for indicating an end of congestion and information for indicating a congestion direction (the congestion direction in this case is downlink); Once the UPF recognizes the end of the downlink congestion, the UPF will no longer change the ECN marking of downlink data packets.

[0287] That is, in such an application scenario, during the period when downlink congestion occurs, the RAN continuously adds congestion information in each uplink data packet of the first QoS flow, and the UPF also changes the ECN mark of the corresponding downlink data packet to CE.

[0288] When the congestion ends, the RAN stops adding congestion information to each uplink data packet of the first QoS flow. When congestion information is no longer received, the UPF can remove the congestion status of the first QoS flow and stop changing the ECN marking of downlink data packets.

[0289] In step S29, after receiving the uplink data packet from the RAN, the UPF can send the second information to the SMF via N4 interface signaling, or the UPF directly publishes the second information to other NFs (e.g., SMF, PCF, NEF, AF) via the service interface.

[0290] In step S30, when the congestion information (mainly downlink congestion information in this case) is transmitted to the PCF via control plane signaling, the congestion information may be transmitted by the RAN to the AMF, forwarded by the AMF to the SMF, and further forwarded by the SMF to the PCF; For example, congestion information is transmitted via N4 interface messages.

[0291] In step S31, when congestion information (in this case, mainly downlink congestion information) is transmitted to the UPF via control plane signaling, it may be sent by the RAN to the AMF, forwarded by the AMF to the SMF, and further forwarded by the SMF to the UPF.

[0292] According to an embodiment of the present invention, when a QoS flow of a terminal is congested in the RAN, the RAN continuously reports congestion information in each uplink packet of the QoS flow during the congestion period to realize an explicit indication of the congestion, and when the congestion ends, stops sending all congestion marks to implicitly indicate the end of the congestion. This allows the congestion status to be updated in real time, so that even if the RAN network element is changed, the server or client can timely obtain the congestion status and ensure the throughput of the service data stream. In addition, the embodiment of the present invention clearly defines how to report information at a critical time when a transition occurs from a state in which the congestion reporting condition is met to a state in which the congestion reporting condition is not met, thereby ensuring an accurate indication of the congestion status.
