Description

Technical Field

[0001] (Cross - reference to related applications) This application claims the priority of Chinese Patent Application No. 202211139954.1, filed in China on September 19, 2022, and all of its contents are incorporated herein by reference.

[0002] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to an information processing method and a communication device.

Background Art

[0003] An external application or terminal can subscribe to the congestion status information of a specific service data stream in a 5th - Generation (5G) communication system (5GS). The congestion in 5GS mainly occurs at the air interface. In related technologies, mainly, a radio access network (RAN) reports congestion monitoring. Also, in some cases, a user equipment (UE) monitors uplink congestion.

[0004] In related technologies, in a scenario where a terminal is switched from a source RAN to a target RAN, the congestion status may be different between the source RAN and the target RAN. When the terminal is not congested in the target RAN, the target RAN network element may not need to operate. If a server or a client does not recognize that the RAN network element of the service target has already been changed, it will determine that the congestion is still continuing.

[0005] From the above, it can be seen that there is a problem in that the congestion status information in related technologies is not updated in a timely manner, and the throughput of the service data stream decreases.

The technologies described herein can also be used in other systems and wireless technologies in addition to the systems and wireless technologies mentioned above.

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

[0026] There are several methods for reporting congestion in related technologies, as described below.

[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 the user plane network elements of the Core Network (CN) (e.g., User Plane Function (UPF)), 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 congestion information to a CN control plane network element (e.g., one of the Access Management Function (AMF), Session Management Function (SMF), or Policy Control Function (PCF)), and a CN network element (e.g., one of the Network Exposure Function (NEF) or PCF) discloses 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 congestion status information.

[0031] Currently, we need to solve the following problems:

[0032] Scenario 1: When a terminal switches from the source RAN to the target RAN, if congestion exists for the first target in the source RAN, and the first congestion level or the start of congestion for the first target is reported, when the terminal switches to the target RAN, there is a possibility that the congestion or the first congestion level for the first target will disappear. However, the target RAN is unaware that the source RAN previously reported congestion information for the first target, and therefore does not report congestion-related information for the first target. As a result, the server or client determines that the congestion for the first target is still continuing.

[0033] Scenario 2: Because radio link failures can occur when connecting a UE to a RAN, if the RRC is re-established in a new RAN, the new RAN may not be able to obtain the UE context of the UE in the previous RAN (including the latest congestion information, congestion level, etc.).

[0034] As a solution, when congestion reporting conditions are met (e.g., congestion begins or reaches a congestion level), the RAN network element continuously carries congestion information in uplink data packets. Until the congestion reporting conditions are no longer met (e.g., congestion ends), the RAN continues to carry congestion information in uplink data packets, implicitly indicating the end of congestion. In this way, when a terminal moves to another RAN, there is no congestion in the QoS flow, so it does not operate, which is equivalent to implicitly indicating the end of congestion or the disappearance of congestion.

[0035] However, the following issues still need to be resolved.

[0036] Problem 1: When downlink congestion occurs, there is a possibility that uplink data packets may not exist. In this case, down How to report link congestion information still needs to be resolved.

[0037] Problem 2: The transition from a state where the congestion reporting condition is met to a state where the congestion reporting condition is not met is critical. Therefore, in addition to the final time of congestion, it can also represent the start time when congestion disappears. At this point, it is still unclear whether congestion information should be reported, whether congestion information should not be reported and implicitly indicate that there is no congestion, or whether the absence of congestion should be explicitly reported. This needs to be resolved.

[0038] The same applies to "the occurrence of a transition from a state where congestion reporting conditions are not met to a state where congestion reporting conditions are met."

[0039] problem 3 The UE's QoS flow is unclear regarding whether the first communication device will report congestion information last when congestion occurs at the first communication device, the UE switches from the first communication device to another communication device, and the UE moves away from the first communication device. This needs to be resolved.

For example, when the congestion information includes information for indicating the start or occurrence of downlink congestion, the congestion information is downlink congestion information.

[0176] The transition from a state without congestion to a state where congestion occurs is a critical point between the state without congestion and the state where congestion occurs, and can represent not only the final time when congestion is absent, but also the start time when congestion occurs.

[0177] In one embodiment, if the fulfillment of the congestion reporting condition includes a transition from a state where congestion occurs to a state where there is no congestion, then the failure to fulfill the congestion reporting condition does not include a transition from a state where congestion occurs to a state where there is no congestion. The same applies in the reverse case.

[0190] According to embodiments of the present invention, in one embodiment, when a terminal's QoS flow becomes congested in the RAN, during congestion, the RAN continuously reports congestion information in each uplink packet of the QoS flow to provide an explicit indication of congestion. When congestion ends, it stops transmitting all congestion marks to implicitly indicate the end of congestion, thereby updating the congestion status in real time. Thus, even if the RAN network element is changed, the core network element, server, or client can acquire the congestion status in a timely manner and guarantee the throughput of the service data stream. In another embodiment, during periods without congestion, the RAN continuously reports no congestion information in each uplink packet of the QoS flow to provide an explicit indication of no congestion.

[0228] Selectively, the first period is one of the periods between the first start time and the first end time, and the period during which congestion occurs. The second period is a period during which congestion ends or does not occur. The first start time is one of the following: the time when the congestion reporting conditions are met or congestion occurs, or the time after the congestion reporting conditions are met or congestion occurs. The first termination time is one of the following: the transmission time of the last uplink data packet carrying congestion information; the time when the congestion reporting conditions are no longer met or congestion ends; the time when the congestion reporting conditions are not met or there is no congestion; the time when the terminal leaves the first communication device; the time when the first target is released; the time when the first timer stops; the time when the second timer stops; the time after the transmission of the last uplink data packet carrying congestion information; the time after the congestion reporting conditions are no longer met or congestion ends; the time after the congestion reporting conditions were not met or there was no congestion; the time after the terminal leaves the first communication device; the time after the first target is released; the time after the first timer stops; or the time after the second timer stops.

[0229] The uplink data packets received by the second communication device are transmitted by a RAN network element. Typically, the RAN network element transmits the uplink data packets to the AMF, the AMF forwards the uplink data packets to the SMF, and the SMF forwards the uplink data packets to the second communication device.

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

[0231] According to an embodiment of the present invention, when a terminal's QoS flow becomes congested in the RAN, during congestion, the RAN continuously reports congestion information in each uplink packet of the QoS flow to provide explicit indication of congestion. When congestion ends, it stops transmitting all congestion marks to implicitly indicate the end of congestion. This updates the congestion status in real time, so that even if the RAN network element changes, the CN can acquire the congestion status in a timely manner and disclose it to the server or client, and the server or client can acquire the congestion status in a timely manner and guarantee the throughput of the service data stream. Furthermore, an embodiment of the present invention ensures accurate indication of the congestion status by clearly defining how information is reported at the critical point when a transition occurs from a state where the congestion reporting conditions are met to a state where the congestion reporting conditions are not met.

[0232] In the following, the transmission state of uplink data packets in different cases according to embodiments of the present invention will be explained with examples as follows.

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

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

[0235] As shown in Figure 5b, if no uplink data packets for the first QoS flow exist within the first period, the first communication device generates a first dummy data packet carrying congestion information at the first start time, and a second dummy data packet that does not carry congestion information or first status information at the first end time. Not carrying the first status information indicates that the second dummy data packet does not need to carry any congestion status information (for example, not carrying the first bit, or setting the first bit to 0).

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

[0237] Case 3 As shown in Figure 6a, if no uplink data packets for the first QoS flow exist at the 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 no uplink data packets for the first QoS flow exist at the 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] What needs to be explained here is that the first start time is the time when the congestion reporting conditions are met or congestion occurs, and the first end time is the time when the congestion reporting conditions are no longer met or congestion ends.

[0239] In one embodiment, the time interval between the target time (e.g., first start time, first end time) and the target time can be the processing time.

[0240] The aforementioned processing time is sufficient to perform the first, second, third, or fourth operation. For example, it is sufficient to have congestion information or first information carried in the uplink data packet of the first QoS flow, and sufficient to construct a dummy data packet that carries congestion information or first information.

[0241] As shown in Figure 6b, the operation for the first start time is the same as in Figure 6a, and a detailed explanation is omitted here. The difference is that if there are no uplink data packets for 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 for the first start time is the same as in Figure 6a, and a detailed explanation is omitted here. The difference is that if there are no uplink data packets for 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 As shown in Figure 7a, if no uplink data packets of the first QoS flow exist within the first time interval, the first communication device generates a first dummy data packet carrying congestion information and transmits the first dummy data packet. If no uplink data packets of the first QoS flow exist within the 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 needs to be explained here is that the first time interval is the time interval starting from the first start time, and the second time interval is the time interval starting from the first end time.

[0245] As shown in Figure 7b, the operation of the first start time is the same as in Figure 7a, and a detailed explanation is omitted here. The difference is that if there are no uplink data packets 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 in Figure 7a, and a detailed explanation is omitted here. The difference is that if there are no uplink data packets 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 Figure 8a, if no uplink data packets for the first QoS flow exist at the first start time, the first communication device starts the first timer, generates a first dummy data packet carrying congestion information when the first timer times out, and simultaneously restarts the first timer. The process is then repeated, and when an uplink data packet for the first QoS flow is received at a certain time, the timing of the first timer is interrupted, congestion information is reported via the uplink data packet for the first QoS flow, and the first timer is restarted. When the first timer times out, a first dummy data packet carrying congestion information is generated, and the first timer is restarted. The process is then repeated, and when the first end time is reached, a first dummy data packet carrying congestion information is generated, and the first timer is stopped.

[0248] As shown in Figure 8b, the operation of the first start time is the same as in Figure 8a, and a detailed explanation 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 in Figure 8a, and a detailed explanation is 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 at the same time. The first communication device transmits the second dummy data packet.

[0250] Case 6 As shown in Figure 9, if no uplink data packets for the first QoS flow exist at the first start time, the first communication device activates the first timer and generates a first dummy data packet carrying congestion information when the first timer times out.

[0251] Selectively, if no uplink data packets for the first QoS flow exist when the first termination time is reached, the first communication device activates 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, it generates a second dummy data packet that does not carry congestion information or first status information. In yet another embodiment, when the first termination time is reached, it generates a second dummy data packet carrying second information.

[0252] Selectively, when the first termination time is reached, the first dummy data packet is generated.

[0253] Case 7 As shown in Figure 10a, if no uplink data packets for the first QoS flow exist at the first end time, the first communication device starts 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. When it receives an uplink data packet for the first QoS flow at a certain time, it interrupts the timing of the second timer, reports the first information via the uplink data packet for the first QoS flow, and then restarts the second timer. When the second timer times out, it generates a second dummy data packet carrying the first information and simultaneously restarts the second timer. The above process is then repeated again, and when the second start time is reached, it generates a first dummy data packet carrying congestion information and simultaneously stops the second timer.

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

[0255] Case 8 As shown in Figure 11a, if no uplink data packets for the first QoS flow exist at the first end time, the first communication device activates the 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 congestion information when the second start time is reached.

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

[0257] Application Scene 1 of the embodiment of the present invention mainly describes an uplink congestion processing process. Referring to Figure 12, it includes the following steps S11 to S19.

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

[0259] Selectively, the congestion monitoring request may be forwarded to the 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. There are four options for transmitting congestion information: 1) steps S14-S15, 2) steps S16-S17, 3) step S18, and 4) step 19.

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

[0263] The uplink data packet carries congestion information including information to indicate the start of congestion, information to indicate the congestion level, and information to indicate the direction of congestion (in this case, the direction of congestion is uplink). 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 RAN uplink data packet, the UPF changes the ECN mark in the uplink data packet to a value indicating congestion (i.e., changes the ECN mark to CE) and transmits the uplink data packet to the server.

[0265] Step S15 corresponds to step S14, meaning that the UPF performs an operation to change the ECN mark each time it receives an uplink data packet.

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

[0267] The uplink data packet carries congestion information, including information to indicate the start of congestion, information to indicate the congestion level, and information to indicate the direction of congestion. 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 RAN uplink data packet, the UPF sends the second information to the SMF via N4 interface signaling, or the UPF directly exposes 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 direction of congestion.

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

[0271] In other words, in such application scenarios, during the period when uplink congestion occurs, the RAN continuously adds congestion information to each uplink data packet in the first QoS flow, and the UPF also changes the ECN mark of the corresponding uplink data packet to CE. Furthermore, in such application scenarios, while the RAN continuously adds congestion information to each uplink data packet in the first QoS flow during the period when uplink congestion occurs, the UPF reports the congestion information only once, not multiple times, via N4 signaling.

[0272] When 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 delete the congestion status of the first QoS flow and notify of the end of congestion via N4 signaling, or stop changing the ECN mark. In other words, it implicitly notifies of the end of congestion.

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

[0274] In step S19, when transmitting congestion information (in this case, mainly uplink congestion information) to the UPF via control plane signaling, it is also possible to transmit it to the AMF via RAN, forward it to the SMF via AMF, and then forward it to the UPF via SMF.

[0275] Application scenario 2 of the embodiment of the present invention Application scenario 2 of the embodiment of the present invention mainly describes a downlink congestion processing process. Referring to Figure 13, it includes the following steps S21 to S31.

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

[0277] Selectively, the congestion monitoring request may be forwarded to the 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-S28, 2) step S29, 3) step S30, and 4) step S31.

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

[0281] The uplink data packet carries congestion information, including information to indicate the start of congestion and information to indicate the direction of congestion (in this case, the direction of congestion is downlink). 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 sent from the received server is changed to a value indicating the occurrence of congestion (i.e., the ECN mark is changed to CE).

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

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

[0286] The uplink data packet carries congestion information, including information to indicate the end of congestion and information to indicate the direction of congestion (in this case, the direction of congestion is downlink). When UPF recognizes the end of downlink congestion, it stops changing the ECN mark on downlink data packets.

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

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

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

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

[0291] In step S31, when transmitting congestion information (in this case, mainly downlink congestion information) to the UPF via control plane signaling, it is also possible to transmit it to the AMF via RAN, forward it to the SMF via AMF, and then forward it to the UPF via SMF.

[0292] According to an embodiment of the present invention, when a terminal's QoS flow becomes congested in the RAN, during congestion, the RAN continuously reports congestion information in each uplink packet of the QoS flow to provide explicit indication of congestion. When congestion ends, it stops transmitting all congestion marks, implicitly indicating the end of congestion. This allows for real-time updates of the congestion status, and therefore, even if the RAN network element changes, the server or client can acquire the congestion status in a timely manner and guarantee the throughput of the service data stream. Furthermore, the embodiment of the present invention ensures accurate indication of the congestion status by clearly defining how information is reported at the critical point where a transition occurs from a state where the congestion reporting conditions are met to a state where the congestion reporting conditions are not met.
