Description

[0002] Currently, the Application Function (AF) network element can obtain the round-trip delay (RTD) of the Quality of Service (QoS) flow of a certain service (such as the Extended Reality (XR) service). In this way, the application layer can adjust the encoding method of the data packet according to the round-trip delay of the QoS flow to ensure the transmission quality of the application layer data, thereby improving the user experience.

[0041] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0042] The following describes the terms involved in the embodiments of the present application.

[0043] 1. Exposure of 5G system information

[0044] Targeting Extended Reality Media (XRM) business

[0045] Currently, the research background on how the network can provide information or capabilities of extended reality media (XRM) services to AF network elements is as follows:

[0046] In protocol version 18, the 5G core network can disclose the following information to the AF network element based on Quality of Service (QoS) monitoring: congestion information, data rate information, and round-trip delay.

[0047] Congestion information can be exposed through the Nupf_EventExposure service from the User Plane Function (UPF) network element to the AF, or through the Low Latency, Low Loss, Scalable Throughput (L4S) method based on the user plane.

[0048] The data rate information can be measured and reported by the PSAUPF network element to the AF network element through the Nupf_EventExposure service or through the Session Management Function (SMF) network element / Policy Control Function (PCF) network element / Network Exposure Function (NEF) network element;

[0049] For round trip delay, this parameter is disclosed by the PCF network element to the NEF network element / AF network element.

[0050] Based on the AF network element request, the 5G system can disclose the following information according to the QoS monitoring defined in clause 5.33.3 and / or clause 5.45:

[0051] For uplink (UL) and / or downlink (DL) congestion monitoring, the SMF element requests the NG-RAN to report information to the PSAUPF element via the GPRS Tunnel Protocol-Userplane (GTP-U) header, based on the PCF element's local Policy Control and Charging (PCC) rules. The information reported by the NG-RAN is used to support congestion exposure and support the L4S Explicit Congestion Notification (ECN) marking in the PSA UPF element as described in Section 5.37.3.3. In the case of congestion exposure, the PSAUPF element exposes UL and / or DL congestion information via the Nupf_EventExposure service or via the SMF element, PCF element, or NEF element (as described in Section 5.8.2.18). This applies to both Guaranteed Bit Rate (GBR) and GBR QoS flows.

[0052] The UL and / or DL data rate information of a QoS flow may be measured and disclosed to the AF network element in one of the following ways upon request by the SMF network element:

[0053] The PSAUPF network element is measured and reported via the Nupf_EventExposure service or the SMF network element / PCF network element / NEF network element as described in clause 5.8.2.18.

[0054] The round trip delay for multiple QoS flows (e.g., UL and DL split into two flows) of an XR service in the same PDU session is determined based on the QoS monitoring of the packet delay for a single QoS flow as described in clause 5.33.3. The AF network element provides the necessary information in the request so that the PCF network element can derive the relevant QoS monitoring requirements for each PCC rule. The PCF network element provides the QoS monitoring policy for the XR service data flow in the PCC rule. The PSAUPF network element reports the delay information for each QoS flow to the SMF network element. The SMF network element reports to the PCF network element. The PCF network element obtains the round trip delay information for the XR service data flow and discloses the information to the AF network element directly or through the NEF network element.

[0065] Step 101: A first communication device obtains at least one of a local configuration and first information.

[0066] In some embodiments of the present application, the first communication device may be a PCF network element. Of course, the first communication device may also be other network elements, which is not limited in the embodiments of the present application.

[0067] In some embodiments of the present application, the above-mentioned local configuration is used to configure the first communication device to send the first information.

[0068] In some embodiments of the present application, the above-mentioned local configuration may be pre-configured in the first communication device by other communication devices, or pre-defined, or agreed upon by a protocol.

[0069] In an embodiment of the present application, the first information is used to request measurement or monitoring of the delay of a data packet set.

[0070] In this embodiment of the present application, the first information includes at least one of the following:

[0071] Information for requesting monitoring of the aggregate delay of data packets;

[0072] Used to subscribe to the information of the delay of data packet aggregation.

[0077] Data packet aggregation delay;

[0078] QoS monitoring parameters, where the QoS monitoring parameters include data packet aggregate delay.

[0099] The data packet set delay can be understood as the delay of the data packet set being transmitted between at least one communication device. The data packet set can include a PDU set, and the number of the data packet set can be one or more.

[0100] In some embodiments of the present application, the first operation includes sending the second information. Optionally, the step 102 can be implemented by the following step 102a.

[0101] Step 102a: The first communication device sends second information to the second communication device according to at least one of the local configuration and the first information.

[0102] It can be seen that since the first communication device only needs to send the first information to the second communication device, it can instruct other communication devices to monitor the delay of the data packet set without sending information to each of the other communication devices, thereby saving the transmission resources of the first communication device.

[0103] In some embodiments of the present application, the first operation includes sending the second information. Optionally, the step 102 can be implemented through the following steps 102b to 102d.

[0104] Step 102b: The first communication device sends a QoS monitoring policy according to at least one of the local configuration and the first information.

[0105] In an embodiment of the present application, the above-mentioned QoS monitoring strategy includes second information.

[0106] In some embodiments of the present application, the first communication device may send a QoS monitoring policy to the second communication device.

[0107] Step 102c: The first communication device sends QoS monitoring parameters according to at least one of the local configuration and the first information.

[0108] In an embodiment of the present application, the above-mentioned QoS monitoring parameters include second information.

[0109] In some embodiments of the present application, the above-mentioned QoS monitoring parameters may include data packet aggregate delay. In the case where the QoS monitoring parameters include data packet aggregate delay, the QoS monitoring parameters may be used to require monitoring of the data packet aggregate delay.

[0110] In some embodiments of the present application, the first communication device may send QoS monitoring parameters to the second communication device.

[0111] Step 102d: The first communications device sends the PCC rule according to at least one of the local configuration and the first information.

[0112] In the embodiment of the present application, the PCC rule includes second information.

[0113] In some embodiments of the present application, the PCC rule may include a data packet aggregate delay. In the case where the PCC rule includes the data packet aggregate delay, the PCC rule may be used to require monitoring of the data packet aggregate delay.

[0114] In some embodiments of the present application, the first communication device may send the PCC rule to the second communication device.

[0115] As can be seen, since the first communication device can send the second information while sending the QoS monitoring policy, QoS monitoring parameters and PCC rules without using additional transmission resources to send the second information, the transmission resources of the first communication device can be saved.

[0116] An embodiment of the present application provides a delay monitoring method, in which a first communication device can obtain a local configuration and at least one of first information, the first information including at least one of information for requesting to monitor the delay of a data packet set and information for subscribing to the delay of a data packet set, and perform a first operation based on the local configuration and at least one of the first information, the first operation including generating a QoS monitoring policy, generating second information, sending a QoS monitoring policy, and sending at least one of the second information, the QoS monitoring policy being used to monitor the delay of a data packet set, and the second information being used to indicate the delay of the monitored data packet set. Since the first communication device can first obtain the local configuration, at least one of the information for requesting to monitor the data packet set delay and the information for subscribing to the data packet set delay, and generate a QoS monitoring policy for monitoring the data packet set delay (and / or send a QoS monitoring policy for monitoring the data packet set delay) based on the local configuration, the information for requesting to monitor the data packet set delay and the information for subscribing to the data packet set delay, the first communication device can instruct other communication devices to monitor the data packet set delay through the QoS monitoring policy, so that other communication devices can monitor at a smaller granularity (i.e., the granularity of the data packet set) to obtain the data packet set delay of the data packet set, i.e., the delay at the media unit granularity, so that the application layer can flexibly adjust the encoding method of the data packet according to the delay at the media unit granularity, thereby avoiding Avoid the situation where the application layer makes inappropriate adjustments to the encoding method of the data packet; and / or, based on the local configuration, the information for requesting to monitor the data packet set delay and at least one of the information for subscribing to the data packet set delay, generate second information for indicating the monitoring of the data packet set delay (and / or send second information for indicating the monitoring of the data packet set delay), so that the first communication device can instruct other communication devices to monitor the data packet set delay through the second information, so that other communication devices can monitor at a smaller granularity (i.e., the granularity of the data packet set) to obtain the data packet set delay of the data packet set, i.e., obtain the delay at the media unit granularity, so that the application layer can flexibly adjust the encoding method of the data packet according to the delay at the media unit granularity, thereby avoiding the situation where the application layer makes inappropriate adjustments to the encoding method of the data packet; in this way, the user experience can be improved. The above-mentioned data packet set delay will be described in detail below.

[0117] In some embodiments of the present application, the above-mentioned data packet aggregate delay includes at least one of the following:

[0118] a time delay during which the data packet set is transmitted between the fifth communication device and the sixth communication device;

[0119] a time delay during which the data packet set is transmitted between the terminal and the sixth communication device;

[0120] The delay during which the data packet set is transmitted between the fifth communication device and the terminal.

[0121] Optionally, the fifth communication device may be an access network device. The sixth communication device may be an anchor gateway. Of course, the fifth communication device and the sixth communication device may also be other network elements, which is not limited in this embodiment of the present application.

[0122] Optionally, the above-mentioned data packet set corresponds to the data packet set delay. It can be understood that the above-mentioned data packet set delay is the delay of the data packet set.

[0123] Optionally, in the case that the at least one communication device includes a fifth communication device and a sixth communication device, the data packet set delay includes a delay during which the data packet set is transmitted between the fifth communication device and the sixth communication device.

[0124] Furthermore, the delay of the above-mentioned data packet set during transmission between the fifth communication device and the sixth communication device includes at least one of the following:

[0125] a time delay during which the set of data packets is transmitted from the fifth communication device to the sixth communication device;

[0128] It can be seen that since the embodiment of the present application stipulates the content of the delay during the transmission of the data packet set between the fifth communication device and the sixth communication device, after the first communication device performs the first operation, other communication devices can accurately monitor the specified delay based on the content to obtain the data packet set delay.

[0129] Here, the delay of transmitting the above-mentioned data packet set from the fifth communication device to the sixth communication device is determined by at least one of the following:

[0130] time at which the fifth communication device receives the first data packet in the data packet set;

[0131] The fifth communication device schedules a time for a first data packet in the data packet set;

[0132] The time when the sixth communication device receives the last data packet in the data packet set.

[0133] The term "scheduling" may be understood to mean starting transmission or sending. The data packet may include a PDU. It should be noted that the time at which a data packet is received in this application may be the same as the time at which the data packet is scheduled, and this is not limited in this application.

[0134] Among them, the delay over which the data packet set is transmitted from the fifth communication device to the sixth communication device can be obtained by adding, subtracting, or averaging at least two of the time when the fifth communication device receives the first data packet in the data packet set, the time when the fifth communication device schedules the first data packet in the data packet set, and the time when the sixth communication device receives the last data packet in the data packet set.

[0135] In some embodiments of the present application, the first data packet in a data packet set may refer to the first data packet in the data packet set based on the data packet sequence number, or may refer to the first data packet in the data packet set that is ultimately received by the corresponding communication device due to jitter or delay during actual transmission, and this is not limited in the present application. In the present application, the first data packet in the data packet set based on the data packet sequence number is used as an example for explanation.

[0136] In some embodiments of the present application, the last data packet in the above-mentioned data packet set may refer to the last data packet in the data packet set based on the data packet sequence number, or may refer to the last data packet in the data packet set that is finally received by the corresponding communication device due to jitter or delay in actual transmission, which is not limited in the present application.

[0137] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the fifth communication device to the sixth communication device, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0138] Here, the delay of transmitting the above-mentioned data packet set from the sixth communication device to the fifth communication device is determined by at least one of the following:

[0142] Among them, the delay during which the data packet set is transmitted from the sixth communication device to the fifth communication device can be obtained by adding, subtracting, or averaging at least two of the time when the sixth communication device sends the first data packet in the data packet set, the time when the fifth communication device receives the last data packet in the data packet set, and the time when the fifth communication device schedules the last data packet in the data packet set.

[0143] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the sixth communication device to the fifth communication device, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0144] Optionally, in the case that the at least one communication device includes a terminal and a sixth communication device, the data packet set delay includes a delay during transmission of the data packet set between the terminal and the sixth communication device.

[0145] Furthermore, the delay of the above-mentioned data packet set during transmission between the terminal and the sixth communication device includes at least one of the following:

[0147] The delay during which the data packet set is transmitted from the sixth communication device to the terminal.

[0148] Among them, the delay of the above-mentioned data packet set from the terminal to the sixth communication device can be understood as: the uplink delay of the data packet set between the terminal and the sixth communication device; the delay of the above-mentioned data packet set from the sixth communication device to the terminal can be understood as: the downlink delay of the data packet set between the terminal and the sixth communication device.

[0149] It can be seen that since the embodiment of the present application stipulates the content of the delay during the transmission of the data packet set between the terminal and the sixth communication device, after the first communication device performs the first operation, other communication devices can accurately monitor the specified delay based on the content to obtain the data packet set delay.

[0150] Here, the time delay of transmitting the above-mentioned data packet set from the terminal to the sixth communication device is determined by at least one of the following:

[0151] The time when the terminal sends the first data packet in the data packet set;

[0152] The time when the sixth communication device receives the last data packet in the data packet set.

[0153] Among them, the delay of transmitting the data packet set from the terminal to the sixth communication device can be obtained by adding the time when the terminal sends the first data packet in the data packet set and the time when the sixth communication device receives the last data packet in the data packet set, or performing a subtraction operation, or averaging operation.

[0154] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the terminal to the sixth communication device, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0155] Here, the delay of transmitting the above-mentioned data packet set from the sixth communication device to the terminal is determined by at least one of the following:

[0156] The time when the sixth communication device sends the first data packet in the data packet set;

[0158] Among them, the delay of transmitting the data packet set from the sixth communication device to the terminal can be obtained by adding the time when the sixth communication device sends the first data packet in the data packet set and the time when the terminal receives the last data packet in the data packet set, or performing a subtraction operation, or averaging operation.

[0159] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the sixth communication device to the terminal, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0160] Optionally, in the case that the at least one communication device includes a fifth communication device and a terminal, the data packet set delay includes a delay during which the data packet set is transmitted between the fifth communication device and the terminal.

[0161] Furthermore, the delay during which the above-mentioned data packet set is transmitted between the fifth communication device and the terminal includes at least one of the following:

[0162] the time delay of the data packet set from the terminal to the fifth communication device;

[0163] The delay during which the data packet set is transmitted from the fifth communication device to the terminal.

[0165] It can be seen that since the embodiment of the present application stipulates the content of the delay during the transmission of the data packet set between the fifth communication device and the terminal, after the first communication device performs the first operation, other communication devices can accurately monitor the specified delay based on the content to obtain the data packet set delay.

[0166] Here, the time delay of transmitting the above-mentioned data packet set from the terminal to the fifth communication device is determined by at least one of the following:

[0167] The time when the terminal sends the first data packet in the data packet set;

[0168] the time at which the fifth communication device receives the last data packet in the data packet set;

[0169] The fifth communication device schedules the time of the last data packet in the data packet set.

[0170] Among them, the delay over which the data packet set is transmitted from the terminal to the fifth communication device can be obtained by adding, subtracting, or averaging at least two of the time when the terminal sends the first data packet in the data packet set, the time when the fifth communication device receives the last data packet in the data packet set, and the time when the fifth communication device schedules the last data packet in the data packet set.

[0172] Here, the delay of transmitting the above-mentioned data packet set from the fifth communication device to the terminal is determined by at least one of the following:

[0173] time at which the fifth communication device receives the first data packet in the data packet set;

[0178] It should be noted that, with respect to the delay included in the delay for transmission of a data packet set between the terminal and the sixth communication device, and the content for determining the delay for transmission of a data packet set between the terminal and the sixth communication device, reference can be made to the specific description of the delay included in the delay for transmission of a data packet set between the fifth communication device and the sixth communication device, and the content for determining the delay for transmission of a data packet set between the fifth communication device and the sixth communication device in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0179] It should be noted that, with respect to the delay included in the delay for transmission of a data packet set between the fifth communication device and the terminal, and the content of determining the delay for transmission of a data packet set between the fifth communication device and the terminal, reference can be made to the specific description of the delay included in the delay for transmission of a data packet set between the fifth communication device and the sixth communication device, and the content of determining the delay for transmission of a data packet set between the fifth communication device and the sixth communication device in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0180] In some embodiments of the present application, after the above step 102, the delay monitoring method provided by the embodiment of the present application may further include the following steps 103 and 104.

[0181] Step 103: The first communication device receives third information.

[0182] In this embodiment of the present application, the third information includes at least one of the following:

[0183] Monitoring results of the aggregate delay of monitoring data packets;

[0184] Event notifications;

[0185] First identification information.

[0186] In an embodiment of the present application, the above-mentioned first identification information is used to identify at least one of the following: an event; a data packet set; a data flow; a QoS flow.

[0187] Optionally, the monitoring result of monitoring the data packet aggregate delay may include the data packet aggregate delay.

[0188] Optionally, the above event notification may include a data packet aggregation delay.

[0189] In the embodiments of the present application, the above-mentioned event notification can be understood as the third communication device subscribing to certain events from the network. When the conditions for the event are met, the network sends an event notification message to the third communication device. For example, when the event is the aggregate delay of data packets, the event notification can be understood as the network sending an event notification message to the third communication device, and the event notification message includes the aggregate delay of data packets.

[0190] Optionally, the data packet set (and / or event, and / or data flow, and / or QoS flow) identified by the first identification information is the data packet set (and / or event, and / or data flow, and / or QoS flow) where the monitoring result of monitoring the data packet set delay is located.

[0191] Optionally, in the case where the first identification information identifies a data packet set, the first identification information may specifically include at least one of the following: a data packet set sequence number, indication information of the last data packet in the data packet set, a data packet sequence number within the data packet set, a size of the data packet set, and an importance of the data packet set, wherein the importance of the data packet set is used to indicate the relative importance of the data packet set relative to other data packet sets in the QoS flow.

[0192] In some embodiments of the present application, the first communication device may receive the third information from the at least one communication device. For example, the first communication device may receive the third information from a fifth communication device.

[0193] Among them, the first communication device can receive the third information from the fifth communication device through the AMF network element and the second communication device.

[0194] Step 104: The first communication device sends third information to the third communication device.

[0195] In some embodiments of the present application, the first communication device may send the third information directly to the third communication device, or the first communication device may send the third information to the third communication device through the fourth communication device.

[0196] It can be understood that when the third information includes at least one of the monitoring results and event notifications of monitoring data packet set delay, the third communication device can directly obtain the data packet set delay from at least one of the monitoring results and event notifications of monitoring data packet set delay; when the third information includes first identification information, the third communication device can obtain the data packet set delay from the event and / or data packet set and / or data flow and / or QoS flow identified by the first identification information.

[0197] It can be seen that after receiving the third information, the first communication device can also send the third information to the third communication device, so that the third communication device can obtain the data packet set delay. In this way, the third communication device can flexibly adjust the encoding method of the data packet according to the data packet set delay, thereby reducing the impact of network fluctuations on the transmission quality of the data packet.

[0198] Figure 3 FIG. 1 shows a flow chart of a delay monitoring method provided by an embodiment of the present application. Figure 3 As shown, the delay monitoring method provided in the embodiment of the present application may include the following steps 201 and 202.

[0199] Step 201: A second communication device obtains at least one of a local configuration and second information.

[0200] In some embodiments of the present application, the second communication device may be a SMF network element. Of course, the second communication device may also be other network elements, which is not limited in the embodiments of the present application.

[0201] In some embodiments of the present application, the above-mentioned local configuration is used to configure the second communication device to perform the first operation.

[0202] In some embodiments of the present application, the above-mentioned local configuration may be pre-configured in the second communication device by other communication devices, or may be pre-defined, or agreed upon by a protocol.

[0203] In an embodiment of the present application, the second information is used to indicate the delay of monitoring data packet aggregation.

[0204] It should be noted that, for the description of the second information, reference can be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0205] In some embodiments of the present application, before the above step 201, the delay monitoring method provided by the embodiment of the present application may further include the following step 200.

[0206] Step 200: The second communication device receives second information from the first communication device.

[0207] It can be seen that since the first communication device only needs to send the first information to the second communication device, it can instruct other communication devices to monitor the delay of the data packet set without sending information to each of the other communication devices, thereby saving the transmission resources of the first communication device.

[0208] In some embodiments of the present application, before the above step 201, the delay monitoring method provided by the embodiment of the present application may further include at least one of the following steps 210, 211 and 212.

[0209] Step 210: The second communication device receives a QoS monitoring policy.

[0210] In an embodiment of the present application, the above-mentioned QoS monitoring strategy includes second information.

[0211] In some embodiments of the present application, the second communication device may receive a QoS monitoring policy from the first communication device.

[0212] Step 211: The second communication device receives QoS monitoring parameters.

[0213] In an embodiment of the present application, the above-mentioned QoS monitoring parameters include data packet aggregation delay.

[0214] In some embodiments of the present application, the above-mentioned QoS monitoring parameters may include data packet aggregate delay. In the case where the QoS monitoring parameters include data packet aggregate delay, the QoS monitoring parameters may be used to require monitoring of the data packet aggregate delay.

[0215] In some embodiments of the present application, the second communication device may receive QoS monitoring parameters from the first communication device.

[0216] Step 212: The second communication device receives the PCC rule.

[0217] In the embodiment of the present application, the PCC rule includes second information.

[0218] In some embodiments of the present application, the PCC rule may include a data packet aggregate delay. In the case where the PCC rule includes the data packet aggregate delay, the PCC rule may be used to require monitoring of the data packet aggregate delay.

[0219] In some embodiments of the present application, the second communication device may receive the PCC rule from the first communication device.

[0220] As can be seen, since the first communication device can send the second information while sending the QoS monitoring policy, QoS monitoring parameters and PCC rules without using additional transmission resources to send the second information, the transmission resources of the first communication device can be saved.

[0221] Step 202: The second communication device performs a second operation according to at least one of the local configuration and the second information.

[0222] In the embodiment of the present application, the second operation includes at least one of the following:

[0223] Generate N4 rules;

[0224] generating fourth information;

[0225] generating fifth information;

[0226] sending fourth information to a fifth communication device;

[0227] The fifth information is sent to the sixth communication device.

[0228] In an embodiment of the present application, the above-mentioned N4 rule is used to monitor the data packet aggregate delay; the above-mentioned fourth information is used to instruct the fifth communication device to monitor the data packet aggregate delay; the above-mentioned fifth information is used for at least one of the following: instructing the sixth communication device to monitor the data packet aggregate delay; instructing the sixth communication device to receive the data packet aggregate delay sent by the fifth communication device; instructing the sixth communication device to send the data packet aggregate delay to the third communication device.

[0229] In some embodiments of the present application, the second operation includes sending fourth information to the fifth communication device. Optionally, step 202 can be implemented by at least one of the following steps 202a and 202b.

[0230] Step 202a: The second communication device sends the QoS profile to the fifth communication device according to at least one of the local configuration and the second information.

[0231] In an embodiment of the present application, the above-mentioned QoS file includes fourth information.

[0232] In some embodiments of the present application, the above-mentioned QoS file may be used to require the fifth communication device to monitor the delay of a data packet set.

[0233] Step 202b: The second communication device sends a QoS monitoring request message to the fifth communication device according to the local configuration and at least one of the second information.

[0234] In an embodiment of the present application, the above-mentioned QoS monitoring request message includes fourth information.

[0235] In some embodiments of the present application, the QoS monitoring request message may be used to request the fifth communication device to monitor the aggregate delay of data packets.

[0236] As can be seen, since the second communication device can send the fourth information at the same time as sending the QoS file and the QoS monitoring request message without using additional transmission resources to send the fourth information, the transmission resources of the second communication device can be saved.

[0237] In some embodiments of the present application, the second operation includes sending fifth information to the sixth communication device. Optionally, step 202 may be implemented by at least one of steps 202c to 202e.

[0238] Step 202c: The second communication device sends the N4 rule to the sixth communication device.

[0239] In the embodiment of the present application, the above-mentioned N4 rule includes the fifth information.

[0240] In some embodiments of the present application, the above-mentioned N4 rule is used to require the sixth communication device to monitor the aggregate delay of the data packets.

[0241] Step 202d: The second communication device sends a packet detection rule (PDR) to the sixth communication device.

[0242] In the embodiment of the present application, the above-mentioned PDR includes fifth information.

[0243] In some embodiments of the present application, the PDR is used to require the sixth communication device to monitor the aggregate delay of data packets.

[0244] Step 202e: The second communication device sends a session reporting rule (Session Reporting Rule, SRR) to the sixth communication device.

[0245] In this embodiment of the present application, the above-mentioned SRR includes fifth information.

[0246] In some embodiments of the present application, the SRR is used to require the sixth communication device to monitor the aggregate delay of data packets.

[0247] As can be seen, since the second communication device can send the fifth information while sending at least one of the N4 rule, PDR and SRR without using additional transmission resources to send the fifth information, the transmission resources of the second communication device can be saved.

[0248] An embodiment of the present application provides a delay monitoring method, where a second communication device can obtain at least one of a local configuration and a second information, where the second information is used to indicate monitoring of a data packet aggregate delay, and perform a second operation based on the local configuration and at least one of the second information, where the second operation includes at least one of the following: generating an N4 rule; generating fourth information; generating fifth information; sending the fourth information to a fifth communication device; and sending the fifth information to a sixth communication device; wherein the above-mentioned N4 rule is used to monitor the data packet aggregate delay; the above-mentioned fourth information is used to instruct the fifth communication device to monitor the data packet aggregate delay; and the above-mentioned fifth information is used for at least one of the following: instructing the sixth communication device to monitor the data packet aggregate delay; instructing the sixth communication device to receive the data packet aggregate delay sent by the fifth communication device; and instructing the sixth communication device to send the data packet aggregate delay to the third communication device. Since the second communication device can first obtain at least one of the local configuration and the second information, and generate the N4 rule based on at least one of the local configuration and the second information, the second communication device can instruct other communication devices to monitor the data packet set delay through the N4 rule, so that other communication devices can monitor at a smaller granularity (i.e., the granularity of the data packet set) to obtain the data packet set delay of the data packet set, that is, the delay at the media unit granularity, so that the application layer can flexibly adjust the encoding method of the data packet according to the delay at the media unit granularity, thereby avoiding the situation where the application layer adjusts the encoding method of the data packet inappropriately; and / or, generate the fourth information (and / or send the fourth information to the fifth communication device) based on at least one of the local configuration and the second information, so that the second communication device can instruct other communication devices (and / or the fifth communication device) to monitor the data packet set delay through the fourth information, so that other communication devices (and / or the fifth communication device) can monitor the data packet set delay according to the smaller granularity (i.e., the data packet set delay). The embodiment of the present invention is a method for monitoring the local configuration and the second information to obtain the data packet aggregate delay of the data packet set, that is, the delay of the media unit granularity, so that the application layer can flexibly adjust the encoding method of the data packet according to the delay of the media unit granularity, thereby avoiding the situation where the application layer adjusts the encoding method of the data packet inappropriately; and / or, based on at least one of the local configuration and the second information, generating fifth information (and / or sending the fifth information to the sixth communication device), so that the second communication device can instruct other communication devices (and / or the sixth communication device) to monitor the data packet aggregate delay through the fifth information, so that the other communication devices (and / or the sixth communication device) can monitor according to a smaller granularity (that is, the granularity of the data packet set) to obtain the data packet aggregate delay of the data packet set, that is, the delay of the media unit granularity, so that the application layer can flexibly adjust the encoding method of the data packet according to the delay of the media unit granularity, thereby avoiding the situation where the application layer adjusts the encoding method of the data packet inappropriately; in this way, the user experience can be improved.

[0253] The delay during which the data packet set is transmitted between the fifth communication device and the terminal.

[0254] Optionally, the fifth communication device may be an access network device. The sixth communication device may be an anchor gateway. Of course, the fifth communication device and the sixth communication device may also be other network elements, which is not limited in this embodiment of the present application.

[0255] Optionally, the above-mentioned data packet set corresponds to the data packet set delay. It can be understood that the above-mentioned data packet set delay is the delay of the data packet set.

[0256] Optionally, in the case that the at least one communication device includes a fifth communication device and a sixth communication device, the data packet set delay includes a delay during which the data packet set is transmitted between the fifth communication device and the sixth communication device.

[0257] Furthermore, the delay of the above-mentioned data packet set during transmission between the fifth communication device and the sixth communication device includes at least one of the following:

[0258] a time delay during which the set of data packets is transmitted from the fifth communication device to the sixth communication device;

[0259] The delay over which the data packet set is transmitted from the sixth communication device to the fifth communication device.

[0260] Among them, the delay of the above-mentioned data packet set from the fifth communication device to the sixth communication device can be understood as: the uplink delay of the data packet set between the fifth communication device and the sixth communication device; the delay of the above-mentioned data packet set from the sixth communication device to the fifth communication device can be understood as: the downlink delay of the data packet set between the fifth communication device and the sixth communication device.

[0261] It can be seen that since the embodiment of the present application stipulates the content of the delay during the transmission of the data packet set between the fifth communication device and the sixth communication device, after the second communication device performs the second operation, other communication devices can accurately monitor the specified delay based on the content to obtain the data packet set delay.

[0262] Here, the delay of transmitting the above-mentioned data packet set from the fifth communication device to the sixth communication device is determined by at least one of the following:

[0263] time at which the fifth communication device receives the first data packet in the data packet set;

[0264] The fifth communication device schedules a time for a first data packet in the data packet set;

[0265] The time when the sixth communication device receives the last data packet in the data packet set.

[0266] The term "scheduling" may be understood to mean starting transmission or sending. The data packet may include a PDU. It should be noted that the time at which a data packet is received in this application may be the same as the time at which the data packet is scheduled, and this is not limited in this application.

[0267] Among them, the delay over which the data packet set is transmitted from the fifth communication device to the sixth communication device can be obtained by adding, subtracting, or averaging at least two of the time when the fifth communication device receives the first data packet in the data packet set, the time when the fifth communication device schedules the first data packet in the data packet set, and the time when the sixth communication device receives the last data packet in the data packet set.

[0268] In some embodiments of the present application, the first data packet in a data packet set may refer to the first data packet in the data packet set based on the data packet sequence number, or may refer to the first data packet in the data packet set that is ultimately received by the corresponding communication device due to jitter or delay during actual transmission, and this is not limited in the present application. In the present application, the first data packet in the data packet set based on the data packet sequence number is used as an example for explanation.

[0269] In some embodiments of the present application, the last data packet in the above-mentioned data packet set may refer to the last data packet in the data packet set based on the data packet sequence number, or may refer to the last data packet in the data packet set that is finally received by the corresponding communication device due to jitter or delay in actual transmission, which is not limited in the present application.

[0270] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the fifth communication device to the sixth communication device, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0281] Among them, the delay of the above-mentioned data packet set from the terminal to the sixth communication device can be understood as: the uplink delay of the data packet set between the terminal and the sixth communication device; the delay of the above-mentioned data packet set from the sixth communication device to the terminal can be understood as: the downlink delay of the data packet set between the terminal and the sixth communication device.

[0282] It can be seen that since the embodiment of the present application stipulates the content of the delay during the transmission of the data packet set between the terminal and the sixth communication device, after the second communication device performs the second operation, other communication devices can accurately monitor the specified delay based on the content to obtain the data packet set delay.

[0283] Here, the time delay of transmitting the above-mentioned data packet set from the terminal to the sixth communication device is determined by at least one of the following:

[0284] The time when the terminal sends the first data packet in the data packet set;

[0285] The time when the sixth communication device receives the last data packet in the data packet set.

[0286] Among them, the delay of transmitting the data packet set from the terminal to the sixth communication device can be obtained by adding the time when the terminal sends the first data packet in the data packet set and the time when the sixth communication device receives the last data packet in the data packet set, or performing a subtraction operation, or averaging operation.

[0287] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the terminal to the sixth communication device, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0288] Here, the delay of transmitting the above-mentioned data packet set from the sixth communication device to the terminal is determined by at least one of the following:

[0289] The time when the sixth communication device sends the first data packet in the data packet set;

[0291] Among them, the delay of transmitting the data packet set from the sixth communication device to the terminal can be obtained by adding the time when the sixth communication device sends the first data packet in the data packet set and the time when the terminal receives the last data packet in the data packet set, or performing a subtraction operation, or averaging operation.

[0292] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the sixth communication device to the terminal, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0293] Optionally, in the case that the at least one communication device includes a fifth communication device and a terminal, the data packet set delay includes a delay during which the data packet set is transmitted between the fifth communication device and the terminal.

[0294] Furthermore, the delay during which the above-mentioned data packet set is transmitted between the fifth communication device and the terminal includes at least one of the following:

[0295] the time delay of the data packet set from the terminal to the fifth communication device;

[0296] The delay during which the data packet set is transmitted from the fifth communication device to the terminal.

[0298] It can be seen that since the embodiment of the present application stipulates the content of the delay during the transmission of the data packet set between the fifth communication device and the terminal, after the second communication device performs the second operation, other communication devices can accurately monitor the specified delay based on the content to obtain the data packet set delay.

[0299] Here, the time delay of transmitting the above-mentioned data packet set from the terminal to the fifth communication device is determined by at least one of the following:

[0300] The time when the terminal sends the first data packet in the data packet set;

[0301] the time at which the fifth communication device receives the last data packet in the data packet set;

[0302] The fifth communication device schedules the time of the last data packet in the data packet set.

[0303] Among them, the delay over which the data packet set is transmitted from the terminal to the fifth communication device can be obtained by adding, subtracting, or averaging at least two of the time when the terminal sends the first data packet in the data packet set, the time when the fifth communication device receives the last data packet in the data packet set, and the time when the fifth communication device schedules the last data packet in the data packet set.

[0304] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the terminal to the fifth communication device, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0305] Here, the delay of transmitting the above-mentioned data packet set from the fifth communication device to the terminal is determined by at least one of the following:

[0306] time at which the fifth communication device receives the first data packet in the data packet set;

[0309] Among them, the delay over which the data packet set is transmitted from the fifth communication device to the terminal can be obtained by adding, subtracting, or averaging at least two of the time when the fifth communication device receives the first data packet in the data packet set, the time when the fifth communication device schedules the first data packet in the data packet set, and the time when the terminal receives the last data packet in the data packet set.

[0310] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the fifth communication device to the terminal, other communication devices can accurately determine the data packet set delay according to this content, thereby improving the accuracy of the monitored data packet set delay.

[0311] It should be noted that, with respect to the delay included in the delay for transmission of a data packet set between the terminal and the sixth communication device, and the content for determining the delay for transmission of a data packet set between the terminal and the sixth communication device, reference can be made to the specific description of the delay included in the delay for transmission of a data packet set between the fifth communication device and the sixth communication device, and the content for determining the delay for transmission of a data packet set between the fifth communication device and the sixth communication device in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0312] It should be noted that, with respect to the delay included in the delay for transmission of a data packet set between the fifth communication device and the terminal, and the content of determining the delay for transmission of a data packet set between the fifth communication device and the terminal, reference can be made to the specific description of the delay included in the delay for transmission of a data packet set between the fifth communication device and the sixth communication device, and the content of determining the delay for transmission of a data packet set between the fifth communication device and the sixth communication device in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0313] In some embodiments of the present application, after the above step 202, the delay monitoring method provided by the embodiment of the present application may further include the following steps 203 and 204.

[0314] Step 203: The second communication device receives third information from the fifth communication device.

[0315] In this embodiment of the present application, the third information includes at least one of the following:

[0316] Monitoring results of the aggregate delay of monitoring data packets;

[0317] Event notifications;

[0318] First identification information.

[0319] In an embodiment of the present application, the above-mentioned first identification information is used to identify at least one of the following: an event; a data packet set; a data flow; a QoS flow.

[0320] Optionally, the monitoring result of monitoring the data packet aggregate delay may include the data packet aggregate delay.

[0321] Optionally, the above event notification may include a data packet aggregation delay.

[0322] In the embodiments of the present application, the above-mentioned event notification can be understood as the third communication device subscribing to certain events from the network. When the conditions for the event are met, the network sends an event notification message to the third communication device. For example, when the event is the aggregate delay of data packets, the event notification can be understood as the network sending an event notification message to the third communication device, and the event notification message includes the aggregate delay of data packets.

[0323] Optionally, the data packet set (and / or event, and / or data flow, and / or QoS flow) identified by the first identification information is the data packet set (and / or event, and / or data flow, and / or QoS flow) where the monitoring result of monitoring the data packet set delay is located.

[0324] In some embodiments of the present application, the second communication device may receive the third information from the fifth communication device via the AMF network element. For example, the second communication device may receive an Nsmf_PDUSession_updateSMContextRequest message from the AMF network element, which carries the third information.

[0325] Step 204: The second communication device sends third information to the third communication device.

[0326] In some embodiments of the present application, the second communication device may send the third information to the third communication device through the first communication device. For example, the second communication device may send an Npcf_SMPolicyControl_Update Request message to the first communication device, the message carrying the third information.

[0327] It can be understood that when the third information includes at least one of the monitoring results and event notifications of monitoring data packet set delay, the third communication device can directly obtain the data packet set delay from at least one of the monitoring results and event notifications of monitoring data packet set delay; when the third information includes first identification information, the third communication device can obtain the data packet set delay from the event and / or data packet set and / or data flow and / or QoS flow identified by the first identification information.

[0328] It can be seen that after receiving the third information, the second communication device can also send the third information to the third communication device, so that the third communication device can obtain the data packet set delay. In this way, the third communication device can flexibly adjust the encoding method of the data packet according to the data packet set delay, thereby reducing the impact of network fluctuations on the transmission quality of the data packet.

[0329] Figure 4 FIG. 1 shows a flow chart of a delay monitoring method provided by an embodiment of the present application. Figure 4 As shown, the delay monitoring method provided in the embodiment of the present application may include the following step 301.

[0330] Step 301: The fifth communication device performs operations related to monitoring the delay of a set of data packets.

[0331] In some embodiments of the present application, the fifth communication device may be an access network device. Of course, the fifth communication device may also be other network elements, which is not limited in the embodiments of the present application.

[0332] In some embodiments of the present application, the above-mentioned operation related to monitoring the delay of the data packet set includes at least one of the following:

[0333] Determine the latency of downlink data packets.

[0334] Determine the latency of upstream packets.

[0335] In the embodiment of the present application, the above-mentioned operation related to determining the aggregate delay of downlink data packets includes at least one of the following:

[0336] Receive the first data packet in the data packet set;

[0337] Acquire a first time, where the first time is the time when the sixth communication device receives the first data packet in the data packet set;

[0338] Recording a second time, where the second time is the time when the fifth communication device receives the last data packet in the data packet set, or the second time is the time when the fifth communication device schedules the last data packet in the data packet set;

[0339] Determine a data packet aggregate delay based on the first time and the second time.

[0340] The term "scheduling" may be understood to mean starting transmission or sending. The data packet may include a PDU. It should be noted that the time at which a data packet is received in this application may be the same as the time at which the data packet is scheduled, and this is not limited in this application.

[0341] Optionally, the fifth communication device may receive the first data packet in the data packet set from the sixth communication device.

[0342] It should be noted that, in some implementations, when the fifth communication device sends the first data packet in the data packet set from the sixth communication device, it may need to be forwarded through other communication devices, which is not limited in this application.

[0343] Optionally, the fifth communication device may obtain the first time from the sixth communication device.

[0344] Furthermore, the obtaining of the first time includes: obtaining the first time in a GTP-U header of the first data packet in the data packet set.

[0345] In some embodiments of the present application, the first data packet in a data packet set may refer to the first data packet in the data packet set based on the data packet sequence number, or may refer to the first data packet in the data packet set that is ultimately received by the corresponding communication device due to jitter or delay during actual transmission, and this is not limited in the present application. In the present application, the first data packet in the data packet set based on the data packet sequence number is used as an example for explanation.

[0346] In some embodiments of the present application, the last data packet in the above-mentioned data packet set may refer to the last data packet in the data packet set based on the data packet sequence number, or may refer to the last data packet in the data packet set that is finally received by the corresponding communication device due to jitter or delay in actual transmission, which is not limited in the present application.

[0347] As can be seen, since the fifth communication device can obtain the first time from the first data packet in the data packet set without obtaining the first time through other information, the transmission resources of the sixth communication device can be saved.

[0348] Optionally, the above-mentioned data packet set delay is equal to the second time minus the first time.

[0349] In one example, the complete process of the above-mentioned operations for determining the downlink data packet set delay can be: the fifth communication device receives the first data packet in the data packet set from the sixth communication device, and obtains the first time from the GTP-U header of the first data packet in the data packet set, and then records the second time, so that the fifth communication device can subtract the first time from the second time to obtain the time as the data packet set delay of the data packet set.

[0350] In the embodiment of the present application, the above-mentioned operation related to determining the aggregate delay of uplink data packets includes at least one of the following:

[0351] Receive the first data packet in the data packet set;

[0352] Recording a third time, where the third time is the time when the fifth communication device receives the first data packet in the data packet set, or the third time is the time when the fifth communication device schedules the first data packet in the data packet set;

[0353] Send the third time.

[0354] Optionally, the fifth communication device may receive the first data packet in the data packet set from the terminal.

[0355] Optionally, the sending of the third time includes: including the third time in a GTP-U header of a first data packet in the data packet set, and sending the first data packet in the data packet set.

[0356] It can be seen that since the fifth communication device can include the third time in the data packet to be sent, the fifth communication device can send the third time at the same time as sending the data packet in the data packet set without sending additional information, thereby saving the transmission resources of the fifth communication device.

[0357] Optionally, the sending of the third time includes: sending the third time to a sixth communication device.

[0358] It should be noted that, in some embodiments, the third time may also include the GTP-U header of the last data packet in the data packet set, the GTP-U header of any data packet in the data packet set, or the GTP-U headers of all data packets in the data packet set, which is not limited in this application.

[0359] Optionally, the above-mentioned data packet set delay is equal to the second time minus the first time.

[0360] In one example, the complete process of the above-mentioned operations related to determining the uplink data packet set delay can be: the fifth communication device receives the first data packet in the data packet set from the terminal, and records the third time, and then includes the third time in the GTP-U header of the first data packet in the data packet set, and sends the first data packet, so that the sixth communication device can determine the data packet set delay of the data packet set based on the third time.

[0361] It can be seen that since the embodiment of the present application stipulates a specific process for determining at least one of the uplink data packet set delay and the downlink data packet set usage, the communication device (i.e., the fifth communication device and / or the sixth communication device) can accurately determine the data packet set delay according to the specific process.

[0362] In some embodiments of the present application, before the above step 301, the delay monitoring method provided in the embodiment of the present application may further include the following step 300, and the above step 301 may be specifically implemented by the following step 301a.

[0363] Step 300: The fifth communication device receives fourth information from the second communication device.

[0364] In the embodiment of the present application, the fourth information is used to instruct the fifth communication device to monitor the delay of the data packet set.

[0365] In some embodiments of the present application, the above step 300 can be specifically implemented by at least one of the following steps 300a and 300b.

[0366] Step 300a: The fifth communication device receives a QoS file from the second communication device.

[0367] In an embodiment of the present application, the above-mentioned QoS file includes fourth information.

[0368] In some embodiments of the present application, the above-mentioned QoS file may be used to require the fifth communication device to monitor the delay of a data packet set.

[0369] Step 300b: The fifth communication device receives a QoS monitoring request message from the second communication device.

[0370] In an embodiment of the present application, the above-mentioned QoS monitoring request message includes fourth information.

[0371] In some embodiments of the present application, the QoS monitoring request message may be used to request the fifth communication device to monitor the aggregate delay of data packets.

[0372] As can be seen, since the second communication device can send the fourth information at the same time as sending the QoS file and the QoS monitoring request message without using additional transmission resources to send the fourth information, the transmission resources of the second communication device can be saved.

[0373] Step 301a: The fifth communication device performs operations related to monitoring the delay of a set of data packets according to the fourth information.

[0374] As can be seen, the fifth communication device can quickly start to perform operations related to monitoring the delay of the data packet set under the instruction of the second communication device.

[0375] The present application provides a method for monitoring latency, wherein a fifth communication device can perform operations related to monitoring the use of a data packet set. Because the fifth communication device can monitor at a smaller granularity (i.e., the granularity of the data packet set) to obtain the data packet set latency, i.e., the latency at the media unit granularity, the application layer can flexibly adjust the encoding method for the data packet according to the latency at the media unit granularity. This can avoid situations where the application program makes inappropriate adjustments to the data packet encoding method; thus, the user experience can be improved.

[0376] The following will provide a detailed description of the above data packet aggregation delay.

[0377] In some embodiments of the present application, the above-mentioned data packet aggregate delay includes at least one of the following:

[0378] a time delay during which the data packet set is transmitted between the fifth communication device and the sixth communication device;

[0379] a time delay during which the data packet set is transmitted between the terminal and the sixth communication device;

[0380] The delay during which the data packet set is transmitted between the fifth communication device and the terminal.

[0381] Optionally, the fifth communication device may be an access network device. The sixth communication device may be an anchor gateway. Of course, the fifth communication device and the sixth communication device may also be other network elements, which is not limited in this embodiment of the present application.

[0382] Optionally, the above-mentioned data packet set corresponds to the data packet set delay. It can be understood that the above-mentioned data packet set delay is the delay of the data packet set.

[0383] Optionally, in the case that the at least one communication device includes a fifth communication device and a sixth communication device, the data packet set delay includes a delay during which the data packet set is transmitted between the fifth communication device and the sixth communication device.

[0384] Furthermore, the delay of the above-mentioned data packet set during transmission between the fifth communication device and the sixth communication device includes at least one of the following:

[0385] a time delay during which the set of data packets is transmitted from the fifth communication device to the sixth communication device;

[0386] The delay over which the data packet set is transmitted from the sixth communication device to the fifth communication device.

[0387] Among them, the delay of the above-mentioned data packet set from the fifth communication device to the sixth communication device can be understood as: the uplink delay of the data packet set between the fifth communication device and the sixth communication device; the delay of the above-mentioned data packet set from the sixth communication device to the fifth communication device can be understood as: the downlink delay of the data packet set between the fifth communication device and the sixth communication device.

[0388] It can be seen that since the embodiment of the present application stipulates the content of the delay during the transmission of the data packet set between the fifth communication device and the sixth communication device, the fifth communication device can accurately monitor the specified delay based on the content to obtain the data packet set delay.

[0389] Here, the delay of transmitting the above-mentioned data packet set from the fifth communication device to the sixth communication device is determined by at least one of the following:

[0390] time at which the fifth communication device receives the first data packet in the data packet set;

[0391] The fifth communication device schedules a time for a first data packet in the data packet set;

[0392] The time when the sixth communication device receives the last data packet in the data packet set.

[0438] In some embodiments of the present application, after the above step 301, the delay monitoring method provided by the embodiment of the present application may further include at least one of the following steps 302 and 303.

[0439] Step 302: The fifth communication device sends third information to the third communication device through the sixth communication device.

[0440] In this embodiment of the present application, the third information includes at least one of the following:

[0441] Monitoring results of the aggregate delay of monitoring data packets;

[0442] Event notifications;

[0443] First identification information.

[0444] In an embodiment of the present application, the above-mentioned first identification information is used to identify at least one of the following: an event; a data packet set; a data flow; a QoS flow.

[0445] It can be understood that the fifth communication device can send the third information to the third communication device based on the network element of the user plane.

[0446] Optionally, the fifth communication device may directly send the third information to the sixth communication device, so that the sixth communication device may directly send the third information to the third communication device, or may send the third information to the third communication device through the fourth communication device.

[0447] In some embodiments of the present application, the above step 302 can be specifically implemented through the following step 302a.

[0448] Step 302a: The fifth communication device includes the third information in the GTP-U header of the last data packet in the data packet set, and sends the last data packet in the data packet set to the third communication device through the sixth communication device.

[0449] Step 303: The fifth communication device sends third information to the third communication device through the second communication device.

[0450] It can be understood that the fifth communication device can send the third information to the third communication device based on the network element of the control plane.

[0451] Optionally, the fifth communication device can send the third information to the AMF network element so that the AMF network element can send the third information to the second communication device, so that the second communication device can send the third information to the first communication device, and then the first communication device can send the third information directly to the third communication device, or, the third information can be sent to the third communication device through the fourth communication device.

[0453] Step 303a: The fifth communication device includes the third information in a notification control message, and sends the control message to the third communication device through the second communication device.

[0454] It can be seen that since the fifth communication device can send the third information to the third communication device, so that the third communication device can obtain the data packet set delay, the third communication device can flexibly adjust the encoding method of the data packet according to the data packet set delay, thereby reducing the impact of network fluctuations on the transmission quality of the data packet.

[0455] Figure 5 FIG. 1 shows a flow chart of a delay monitoring method provided by an embodiment of the present application. Figure 5 As shown, the delay monitoring method provided in the embodiment of the present application may include the following step 401.

[0456] Step 401: The sixth communication device performs operations related to monitoring the delay of a set of data packets.

[0457] In some embodiments of the present application, the sixth communication device may be an anchor gateway. Of course, the sixth communication device may also be other network elements, which is not limited in the embodiments of the present application.

[0458] In some embodiments of the present application, the above-mentioned operation related to monitoring the delay of the data packet set includes at least one of the following:

[0459] Determine the latency of downlink data packets.

[0460] Determine the latency of upstream packets.

[0461] In the embodiment of the present application, the above-mentioned operation related to determining the aggregate delay of downlink data packets includes at least one of the following:

[0462] Receive the first data packet in the data packet set;

[0463] Recording a first time, where the first time is the time when the sixth communication device receives the first data packet in the data packet set;

[0464] Send as soon as possible.

[0465] Optionally, the sixth communication device may receive the first data packet in the data packet set from the third communication device through the fifth communication device.

[0466] It should be noted that, in some embodiments, when the sixth communication device sends the first data packet in the data packet set from the fifth communication device, it may need to be forwarded through other communication devices (for example, I-UPF), which is not limited in this application.

[0467] Optionally, the sending of the first time includes: including the first time in the GTP-U header of the first data packet in the data packet set, and sending the first data packet in the data packet set.

[0468] As can be seen, since the sixth communication device can send the first time through the first data packet in the data packet set without sending additional information, the transmission resources of the sixth communication device can be saved.

[0469] Optionally, the sending of the first time includes: sending the first time to a fifth communication device.

[0470] In one example, the complete process of the above-mentioned operations related to determining the downlink data packet set delay can be: the sixth communication device receives the first data packet in the data packet set from the third communication device, and records the first time, then includes the first time in the GTP-U header of the first data packet in the data packet set, and sends the first data packet in the data packet set to the fifth communication device, so that the fifth communication device can determine the data packet set delay of the data packet set based on the first time.

[0471] In the embodiment of the present application, the above-mentioned operation related to determining the aggregate delay of uplink data packets includes at least one of the following:

[0472] Receive the first data packet in the data packet set;

[0473] Acquire a third time, where the third time is the time when the fifth communication device receives the first data packet in the data packet set, or the third time is the time when the fifth communication device schedules the first data packet in the data packet set;

[0474] Recording a fourth time, where the fourth time is the time when the sixth communication device receives the last data packet in the data packet set;

[0475] The aggregate delay of the data packets is determined according to the third time and the fourth time.

[0476] The term "scheduling" may be understood to mean starting transmission or sending. The data packet may include a PDU. It should be noted that the time at which a data packet is received in this application may be the same as the time at which the data packet is scheduled, and this is not limited in this application.

[0477] Optionally, the sixth communication device may receive the first data packet in the data packet set from the fifth communication device.

[0478] Optionally, the obtaining of the third time includes: obtaining the third time from a GTP-U header of the first data packet in the data packet set.

[0479] It should be noted that, in some embodiments, the third time may also include the GTP-U header of the last data packet in the data packet set, the GTP-U header of any data packet in the data packet set, or the GTP-U headers of all data packets in the data packet set, which is not limited in this application.

[0480] In some embodiments of the present application, the first data packet in a data packet set may refer to the first data packet in the data packet set based on the data packet sequence number, or may refer to the first data packet in the data packet set that is ultimately received by the corresponding communication device due to jitter or delay during actual transmission, and this is not limited in the present application. In the present application, the first data packet in the data packet set based on the data packet sequence number is used as an example for explanation.

[0481] In some embodiments of the present application, the last data packet in the above-mentioned data packet set may refer to the last data packet in the data packet set based on the data packet sequence number, or may refer to the last data packet in the data packet set that is finally received by the corresponding communication device due to jitter or delay in actual transmission, which is not limited in the present application.

[0482] It can be seen that since the fifth communication device can include the third time in the data packet to be sent, the fifth communication device can send the third time at the same time as sending the data packet in the data packet set without sending additional information, thereby saving the transmission resources of the fifth communication device.

[0483] Optionally, the above-mentioned data packet set delay is equal to the fourth time minus the third time.

[0484] In one example, the complete process of the above-mentioned operations related to determining the uplink data packet set delay can be: the sixth communication device receives the first data packet in the data packet set from the fifth communication device, and obtains the third time from the GTP-U header of the first data packet, and records the fourth time, so that the sixth communication device can subtract the third time from the fourth time to obtain the time as the data packet set delay of the data packet set.

[0485] It can be seen that since the embodiment of the present application stipulates a specific process for determining at least one of the uplink data packet set delay and the downlink data packet set usage, the communication device (i.e., the fifth communication device and / or the sixth communication device) can accurately determine the data packet set delay according to the specific process.

[0486] In some embodiments of the present application, before the above step 401, the delay monitoring method provided in the embodiment of the present application may further include the following step 400, and the above step 401 may be specifically implemented by the following step 401a.

[0487] Step 400: The sixth communication device receives fifth information from the second communication device.

[0488] In some embodiments of the present application, the above step 400 can be specifically implemented by at least one of the following steps 400a to 400c.

[0489] Step 400a: The sixth communication device receives the N4 rule from the second communication device.

[0490] In the embodiment of the present application, the above-mentioned N4 rule includes the fifth information.

[0491] Step 400b: The sixth communication device receives a PDR from the second communication device.

[0492] In the embodiment of the present application, the above-mentioned PDR includes fifth information.

[0493] Step 400c: The sixth communications device receives an SRR from the second communications device.

[0494] In this embodiment of the present application, the above-mentioned SRR includes fifth information.

[0495] As can be seen, since the second communication device can send the fifth information while sending at least one of the N4 rule, PDR and SRR without using additional transmission resources to send the fifth information, the transmission resources of the second communication device can be saved.

[0496] Step 401a: The sixth communication device performs operations related to monitoring the delay of a set of data packets according to the fifth information.

[0497] In the embodiment of the present application, the fifth information is used for at least one of the following:

[0498] instructing the sixth communication device to monitor the aggregate delay of the data packets;

[0499] Instructing the sixth communication device to receive a set delay of data packets sent by the fifth communication device;

[0500] Instruct the sixth communication device to send a data packet aggregate delay to the third communication device.

[0501] As can be seen, the sixth communication device can quickly start to perform operations related to monitoring the delay of the data packet set under the instruction of the second communication device.

[0502] The present embodiment provides a method for monitoring latency, wherein a sixth communication device can perform operations related to monitoring the use of a data packet set. Because the sixth communication device can monitor at a smaller granularity (i.e., the granularity of the data packet set) to obtain the data packet set latency of the data packet set, i.e., the latency at the media unit granularity, the application layer can flexibly adjust the encoding method of the data packet according to the latency at the media unit granularity. Therefore, it can avoid the situation where the application program makes inappropriate adjustments to the data packet encoding method; thus, the user experience can be improved.

[0503] The following will provide a detailed description of the above data packet aggregation delay.

[0504] In some embodiments of the present application, the above-mentioned data packet aggregate delay includes at least one of the following:

[0561] Among them, the delay over which the data packet set is transmitted from the fifth communication device to the terminal can be obtained by adding, subtracting, or averaging at least two of the time when the fifth communication device receives the first data packet in the data packet set, the time when the fifth communication device schedules the first data packet in the data packet set, and the time when the terminal receives the last data packet in the data packet set.

[0562] It can be seen that since the embodiment of the present application stipulates the content of determining the delay of the data packet set transmitted from the fifth communication device to the terminal, the sixth communication device can accurately determine the data packet set delay according to the content, thereby improving the accuracy of the monitored data packet set delay.

[0563] It should be noted that, with respect to the delay included in the delay for transmission of a data packet set between the terminal and the sixth communication device, and the content for determining the delay for transmission of a data packet set between the terminal and the sixth communication device, reference can be made to the specific description of the delay included in the delay for transmission of a data packet set between the fifth communication device and the sixth communication device, and the content for determining the delay for transmission of a data packet set between the fifth communication device and the sixth communication device in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0564] It should be noted that, with respect to the delay included in the delay for transmission of a data packet set between the fifth communication device and the terminal, and the content of determining the delay for transmission of a data packet set between the fifth communication device and the terminal, reference can be made to the specific description of the delay included in the delay for transmission of a data packet set between the fifth communication device and the sixth communication device, and the content of determining the delay for transmission of a data packet set between the fifth communication device and the sixth communication device in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0565] In some embodiments of the present application, after the above step 401, the delay monitoring method provided by the embodiment of the present application may further include the following step 402.

[0566] Step 402: The sixth communication device sends third information to the third communication device.

[0567] In this embodiment of the present application, the third information includes at least one of the following:

[0568] Data packet aggregation delay;

[0569] Monitoring results of the aggregate delay of monitoring data packets;

[0570] Event notifications;

[0571] First identification information.

[0572] In an embodiment of the present application, the above-mentioned first identification information is used to identify at least one of the following: an event; a data packet set; a data flow; a QoS flow.

[0573] Optionally, the sixth communication device may directly send the third information to the third communication device, or may send the third information to the third communication device through the fourth communication device.

[0574] It can be seen that since the sixth communication device can send the third information to the third communication device, so that the third communication device can obtain the data packet set delay, the third communication device can flexibly adjust the encoding method of the data packet according to the data packet set delay, thereby reducing the impact of network fluctuations on the transmission quality of the data packet.

[0575] The information processing method provided in the embodiments of the present application can be executed by an information processing device, a communication device, or a functional module or entity in the communication device. In the embodiments of the present application, the information processing method provided in the embodiments of the present application is illustrated by taking the execution of the information processing method by a communication device as an example.

[0576] Figure 6 FIG. 1 shows a flow chart of an information processing method provided by an embodiment of the present application. Figure 6 As shown, the information processing method provided in the embodiment of the present application may include the following step 501.

[0577] Step 501: A third communication device sends first information to a first communication device.

[0578] In this embodiment of the present application, the first information includes at least one of the following:

[0579] Information for requesting monitoring of the aggregate delay of data packets;

[0580] Used to subscribe to the information of the delay of the aggregated data packets.

[0581] It should be noted that, for the description of the first information, reference can be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0582] In some embodiments of the present application, the above-mentioned information for subscribing to the delay of the data packet set belongs to the QoS monitoring parameter.

[0583] In some embodiments of the present application, the information for subscribing to the delay of a set of data packets includes an event identifier, where the event is one of the following:

[0584] Data packet aggregation delay;

[0585] QoS monitoring parameters, where the QoS monitoring parameters include data packet aggregate delay.

[0586] An embodiment of the present application provides an information processing method, in which a third communication device can send a first message to a first communication device, wherein the first message includes at least one of information for requesting to monitor a data packet set delay and information for subscribing to a data packet set delay. Since the third communication device can send a first message including at least one of information for requesting to monitor a data packet set delay and information for subscribing to a data packet set delay to the first communication device to instruct the first communication device to monitor the data packet set, other communication devices can monitor at a smaller granularity (i.e., the granularity of the data packet set) to obtain the data packet set delay of the data packet set, i.e., obtain the delay at the media unit granularity, so that the third communication device can flexibly adjust the encoding method of the data packet according to the delay at the media unit granularity, thereby avoiding the situation where the third communication device adjusts the encoding method of the data packet inappropriately; in this way, the user experience can be improved.

[0587] It should be noted that for the description of the above-mentioned data packet set delay, reference can be made to the specific description in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0588] In some embodiments of the present application, after the above step 501, the information processing method provided by the embodiment of the present application may further include the following step 502.

[0589] Step 502: The third communication device receives third information.

[0590] In this embodiment of the present application, the third information includes at least one of the following:

[0591] Monitoring results of the aggregate delay of monitoring data packets;

[0592] Event notifications;

[0593] First identification information.

[0594] In an embodiment of the present application, the above-mentioned first identification information is used to identify at least one of the following: an event; a data packet set; a data flow; a QoS flow.

[0595] It should be noted that, for the description of the third communication device receiving the third information, reference can be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0596] It can be seen that since the third communication device can also receive the third information, the third communication device can obtain the data packet set delay, so that the third communication device can flexibly adjust the encoding method of the data packet according to the data packet set delay, thereby reducing the impact of network fluctuations on the transmission quality of the data packet.

[0597] It should be noted that, for the description of the terminal performing relevant operations for monitoring the delay of a set of data packets when at least one of the above-mentioned communication devices includes a terminal, reference can be made to the specific description of the fifth communication device (and / or the sixth communication device) performing relevant operations for monitoring the delay of a set of data packets in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0598] The following will use a number of different examples to illustrate the complete process of each solution provided in the embodiments of the present application.

[0599] Assume that the first communication device is a PCF network element, the second communication device is an SMF network element, the third communication device is an AF network element, the fourth communication device is an NEF network element, the fifth communication device is an access network device (such as RAN), and the sixth communication device is an anchor gateway (such as UPF).

[0600] Example 1: AF network element requests to measure or monitor the delay aggregation of data packets

[0601] like Figure 7 The specific steps are as follows:

[0602] In step 0, a terminal (e.g., UE) may establish a connection with the network, such as a PDU session.

[0603] Step 1: Optionally, the AF network element may send first information for requesting to monitor the aggregate delay of data packets;

[0604] In some embodiments, if the AF network element is not in the trusted domain of the network, step 1 includes step 1a and step 1b, namely, step 1a: the AF network element sends a Nnef_AFsessionwithQoS_Create Request message to the NEF network element, and the Nnef_AFsessionwithQoS_Create Request message carries the first information; step 1b: the NEF network element sends a Npcf_PolicyAuthorization_Subscribe request message to the PCF network element, and the Npcf_PolicyAuthorization_Subscribe request message carries the first information;

[0605] In some embodiments, if the AF network element is in a trusted domain of the network, step 1 includes step 1c, namely, step 1c: the AF network element directly sends an Npcf_PolicyAuthorization_Subscribe request message to the PCF network element, where the message carries the first information;

[0606] Step 2: The PCF network element performs a first operation based on the first information; for example, the PCF network element sends an Npcf_SMPolicyControl UpdateNotify Request message to the SMF network element, where the message carries the second information and / or the QoS monitoring policy;

[0607] In steps 3 and 4, the SMF network element sends an N2 Message message to the RAN based on the second information, where the message carries the fourth information;

[0608] In one embodiment, the SMF network element may send a Namf_Communication_N1N2MessageTransferrequest message to the AMF network element, which carries the fourth information, so that the AMF network element sends an N2Message message to the RAN, which carries the fourth information.

[0609] Step 5: The SMF network element sends an N4 session modification request message to the UPF network element based on the second information, and the message carries the fifth information.

[0610] Example 2: Determine the aggregate delay of uplink data packets. The RAN records the third time and the UPF network element records the fourth time.

[0613] Step 2: The SMF network element sends fifth information to the UPF network element based on the second information, where the fifth information is carried by the SRR;

[0614] Step 3: The SMF network element sends fourth information to the RAN, where the fourth information is carried by the QoS profile.

[0615] In step 4, the terminal (e.g., UE) may send UL data. Optionally, the UE further performs at least one of the following: marking the sequence number of each transmitted data packet set, marking the indication information of the last data packet in each data packet set, marking the sequence number of the data packets in each data packet set, marking the size of each data packet set, marking the importance of each data packet set, and sending the marked information to the RAN and UPF network elements so that the RAN and UPF network elements can identify each data packet set;

[0616] Step 5, RAN records the third time;

[0617] Step 6: RAN sends the third time to the UPF network element;

[0618] Step 7: The UPF network element records the fourth time;

[0619] Step 8: The UPF network element determines the aggregate delay of the data packet;

[0620] Step 9: The UPF network element sends the third information to the AF network element;

[0621] Step 10: The AF network element dynamically adjusts the data encoding method according to the third information.

[0622] Example 3: Determine the aggregate delay of downlink data packets. The UPF network element records the first time and the RAN records the second time.

[0623] like Figure 9 The specific steps are as follows:

[0624] Step 1: The AF network element sends a downlink data packet to the terminal (e.g., UE) through the UPF network element and the RAN.

[0625] Step 2: UPF network element records the first time;

[0626] In one example, option-1:

[0627] Step 3: The UPF network element sends the first time to the RAN;

[0628] Step 4, RAN records the second time;

[0629] Step 5: RAN determines the aggregate delay of the data packets;

[0631] In another example, option-2:

[0632] Step 3, RAN records the second time;

[0633] Step 4: RAN sends the second time to the UPF network element;

[0634] Step 5: The UPF network element determines the aggregate delay of the data packets;

[0635] Step 6: The UPF network element sends the third information to the AF network element.

[0636] Example 4: Determine the aggregate delay of uplink data packets. The UE records the fifth time and the RAN records the sixth time.

[0637] For steps 1 to 4, refer to steps 1 to 4 in Example 2;

[0638] Step 5: For each data packet set, the UE records a fifth time, where the fifth time is the time when the terminal generates the first data packet in the data packet set, or the time when the terminal schedules the first data packet in the data packet set;

[0639] Step 6: The UE sends the fifth time to the RAN. It should be noted that step 6 may occur in step 4, that is, the UE sends the fifth time to the RAN along with UL data.

[0640] Step 7: The RAN records a sixth time, where the sixth time is the time when the RAN receives the last data packet in the data packet set, or the time when the RAN schedules the last data packet in the data packet set;

[0641] Step 8: RAN determines the aggregate delay of the data packets;

[0642] For steps 9 and 10, please refer to steps 9 and 10 in Example 2.

[0643] Example 5: Determine the aggregate delay of downlink data packets. The RAN records the eighth time and the UE records the seventh time.

[0644] Among them, the eighth time is the time when the RAN receives the first data packet in the data packet set, or the time when the RAN schedules the first data packet in the data packet set; the seventh time is the time when the terminal receives the last data packet in the data packet set, or the time when the terminal schedules the last data packet in the data packet set.

[0645] It should be noted that for the specific process of Example 5, reference can be made to the relevant description in Example 3, and the embodiments of this application will not be repeated here.

[0650] In step 3 and step 4, the UPF network element may also send third information to the AF network element through the NEF network element. The third information is carried by the Nupf_EventExposure Notify message, or by the Nupf_EventExposure Notify message and the Nnef_EventExposure Notify message.
