Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a method, apparatus, and network-side device for information reporting. Background Art

[0002] The Local Network Exposure Function (L-NEF) is a localized Network Exposure Function (NEF). The introduction of the L-NEF is mainly to quickly provide a Quality of Service Monitoring Report (QoS Monitoring Report) for an Edge Application Server (EAS) or an Application Function (AF).

[0003] When certain conditions are met, the 5G Core Network (5GC) sends the measured QoS Monitoring Report to the EAS / AF through the User Plane Function (UPF) via the L-NEF. This method is relatively fast, and these three network elements are all local.

[0004] However, if the terminal (User Equipment, UE) causes an EAS relocation due to movement or load balancing, then there will inevitably be a reselection of the L-NEF / NEF. Once the L-NEF / NEF is reselected and the UPF is reconfigured, the previous monitoring and measurement of the user plane function may be interrupted, and the QoS monitoring cannot be reported in a timely manner. Summary of the Invention

However, the following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions. These technologies can also be applied to applications other than NR system applications, such as the 6th Generation (6G) communication system. th Generation, 6G) communication system.

[0025] Figure 1The block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can also be referred to as a terminal device or a user terminal (User Equipment, UE). The terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc. Terminal-side devices.

It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0026] In the prior art, in the scenario of EAS relocation, the result of the packet delay measurement is not received for a period of time. Although the monitoring will also be reported, there will be a reporting delay. At the same time, since there is no data transmission in the original user plane, the monitoring in this scenario is also meaningless and will cause waste of user plane resources.

[0027] The information reporting method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0028] Figure 2 A flowchart showing an information reporting method provided by an embodiment of the present application is shown. This method can be executed by a first network device. As Figure 2As shown, the method may include the following steps:

[0029] Step S201: Obtain target information.

[0030] In the scenario of ESA relocation, the first network device obtains target information.

[0031] It should be understood that ESA relocation includes relocation from the first edge application server EAS1 to the second edge application server EAS2, or relocation from the first application function AF1 to the second application function AF2. Among them, the first edge application server and the first application function are the old edge application server (old EAS) and the old application function respectively, while the second edge application server and the second application function are the new edge application server (new EAS) and the new application function respectively. The first network device is a network device communicatively connected to EAS1 / AF1, and the UE can communicate with EAS1 / AF1 through the first network device.

[0032] The target information may be an end marker, a flow end marker, etc., or may be a last packet notification message sent by the terminal.

[0033] In one implementation, the first network device includes at least one of the following:

[0034] The first user plane function (UPF);

[0035] The first PDU session anchor (PDU Session Anchor, PSA); the PDU session anchor can also be represented by L-PSA.

[0036] The first uplink classifier (Uplink Classifier, UL CL);

[0037] The first break point.

[0038] Step S202: In response to the target information, report the quality of service monitoring for the first edge application server or the first application function.

[0039] Triggered by obtaining the target information, the first network device will trigger a monitoring reporting process. For example, it triggers the Nx Reporting Procedure and reports the QoS monitoring for the first edge application server or the first application function (QoS Monitoring Reporting), and the first network device reports the obtained quality of service monitoring to the first edge application server or the first application function.

[0040] The triggering conditions for QoS Monitoring Reporting of the UPF in 5GC include the following conditions:

[0041] Event triggered;

[0042] Periodic;

[0043] When the time without receiving the result of packet delay measurement exceeds the threshold;

[0044] When the PDU Session is released.

[0045] The embodiment of the present application can obtain the target information, respond to the target information, and report the service quality monitoring for the first edge application server or the first application function, so as to report the QoS Monitoring Reporting in a timely manner.

[0046] Figure 3 Another schematic flowchart of the information reporting method provided by the embodiment of the present application is shown. This method is executed by the first network device, as Figure 3 shown, and this method may include the following steps.

[0047] Step S301: In the case of being relocated from the first edge application server or application function to the second edge application server or application function, obtain the target information. The target information is used to indicate that the data transmission between the first network device and the first edge application server or the first application function has been completed, or to indicate that the data transmission between the first network device and the second network device has been completed.

[0048] It should be understood that there is a communication connection between the first network device and the first edge application server or the first application function, there is a communication connection between the second network device and the second edge application server or the second application function, and there is a communication connection between the first network device and the second network device.

[0049] In one implementation, the first network device includes at least one of the following:

[0050] The first user plane function;

[0051] The first PDU session anchor point;

[0052] First uplink classifier;

[0053] First splitting point.

[0054] The second network device includes at least one of the following:

[0055] Second user plane function;

[0056] Second PDU session anchor point;

[0057] Second uplink classifier;

[0058] Second splitting point.

[0059] It should be understood that the first network device and the second network device can be different devices or the same device. Specific examples are as follows:

[0060] Scenario 1: Relocated from the first edge application server EAS1 to the second edge application server EAS2. Among them, the first network device in communication connection with the EAS1 includes the first uplink classifier UL CL1 and the first PDU session anchor point PSA1, and the second network device in communication connection with the EAS2 includes the second uplink classifier UL CL2 and the second PDU session anchor point PSA2.

[0061] Before relocation, the data sending process from the UE to the EAS1 is UE → UL CL1 → PSA1 → EAS1;

[0062] During the relocation process, the data sending process from the UE to the EAS1 is UE → UL CL2 → UL CL1 → PSA1 → EAS1;

[0063] After the relocation is completed, the data sending process from the UE to the EAS2 is UE → UL CL2 → PSA2 → EAS2.

[0064] Scenario 2: Relocated from the first edge application server EAS1 to the second edge application server EAS2. Among them, both EAS1 and EAS2 are in communication connection with the same UL CL.

[0065] Before relocation, the data sending process from the UE to the EAS1 is UE → UL CL → PSA1 → EAS1;

[0066] During the relocation process, the data sending process from the UE to the EAS1 is UE → UL CL → PSA1 → EAS1;

[0067] After the relocation is completed, the data sending process from the UE to the EAS2 is UE → UL CL → PSA2 → EAS2.

[0068] In the scenario of ESA relocation, the target information obtained by the first network device.

[0069] In one implementation, the obtaining of the target information includes:

[0070] Receiving an End Marker sent by a second network device, where the End Marker is used to indicate that the data transmission between the first network device and the second network device has ended.

[0071] The target of sending the End Marker is the second network device. When the target receives the End Marker, it knows that no more data will be sent from the network element that sent the End Marker. For example, when the second PDU session anchor PSA2 receives the End Marker sent from the first PDU session anchor PSA1, then PSA2 determines that no more data will be sent from PSA1.

[0072] The End Marker is generated by the upper-level second network device and sent to the first network device. For example, taking Scenario 1 as an example, the End Marker can be generated by the second uplink classifier UL CL2, passed through the first uplink classifier UL CL1 and the first PDU session anchor PSA1, and then sent to the second PDU session anchor PSA2; taking Scenario 2 as an example, the End Marker is generated by the uplink classifier UL CL, passed through the first PDU session anchor PSA1, and then sent to the second PDU session anchor PSA2.

[0073] In another implementation, the obtaining of the target information includes:

[0074] Receiving a Flow End Marker sent by a second network device, where the Flow End Marker is used to indicate that the data transmission between the first network device and the first edge application server or the first application function has ended.

[0075] The target of sending the Flow End Marker is the first edge application server EAS1. When the target receives the Flow End Marker sent by the first network device, EAS1 knows that no more data packets will be sent.

[0076] The End Marker is generated by the second network device and sent to the first network device. For example, in Scenario 1, the Flow End Marker can be generated by the second uplink classifier UL CL2, and sent to EAS1 via the first uplink classifier UL CL1 and the first PDU session anchor PSA1; in Scenario 2, the Flow End Marker can be generated by the uplink classifier UL CL and sent to EAS1 via the first PDU session anchor PSA1.

[0077] In another implementation, the target information can be the last packet notification message sent by the terminal. After the UE sends the last data packet to the first edge application server, the UE can generate the last packet notification information (last packet notification) and send it to the first edge application server or the first application function.

[0078] There are multiple methods to send the last packet notification to the first edge application server or the first application function.

[0079] In one implementation, the obtaining of the target information includes:

[0080] Obtaining the last packet notification information sent by the terminal to the first edge application server or the first application function through the application layer, where the last packet notification information is used to indicate that the terminal has sent the last data packet to the first edge application server or the first application function.

[0081] The terminal can send the last packet notification information to the first edge application server or the first application function through the application layer. The first network device can intercept the last packet notification information, thereby determining that the terminal no longer sends data packets to the first edge application server.

[0082] In one implementation, the last packet notification information carries a target packet header marker. When the first network device intercepts the information, it can determine whether it is the last packet notification information by whether the intercepted information carries the target packet header marker.

[0083] In another implementation, the obtaining of the target information includes:

[0084] Receive the last packet notification information sent by the session management function through the N4 session management procedure. The last packet notification information is sent by the terminal to the session management function through a Non-Access Stratum (NAS) message, and is used to indicate that the terminal has sent the last data packet to the first edge application server or the first application function.

[0085] The terminal can send a last packet notification message to the first edge application server or the first application function through a NAS message. The terminal sends the NAS message to the Session Management Function (SMF), and the SMF then forwards it to the first edge application server or the first application function. In addition, after receiving the last packet notification message, the SMF can forward it to the first network device through the N4 session management procedure.

[0086] Step S302, in response to the target information, report the quality of service monitoring for the first edge application server or the first application function.

[0087] In one implementation, after the first network device obtains the End Marker, it will trigger the monitoring and reporting process, and report the quality of service monitoring for the first edge application server or the first application function. For example, when the first network device UPF1, PSA1, UL CL1 or BP1 receives the EndMarker sent by the second network device UPF2, UL CL2, BP2, it triggers the Nx Reporting Procedure and reports the QoS Monitoring for the first edge application server or the first application function.

[0088] In another implementation, after the first network device obtains the Flow End Marker, it will trigger the monitoring and reporting process and report the quality of service monitoring for the first edge application server or the first application function. For example, when the first network device UPF1, PSA1, UL CL1 or BP1 receives the FlowEnd Marker sent by the second network device UPF2, UL CL2, BP2, it triggers the Nx Reporting Procedure and reports the QoS Monitoring for the first edge application server or the first application function.

[0089] In another implementation, after obtaining the last packet notification message, the first network device will trigger a monitoring and reporting process and report the quality of service monitoring for the first edge application server or the first application function. For example, when the first network device, such as UPF1, PSA1, UL CL1, or BP1, obtains the last packet notification sent through the application layer, or obtains the last packet notification sent by the SMF, it triggers the Nx Reporting Procedure and reports the QoS Monitoring for the first edge application server or the first application function.

[0090] It can be seen that the first network device in the embodiment of the present application triggers the reporting of the quality of service monitoring for the first edge application server or the first application function by obtaining the end identifier, the flow end identifier, or the last packet notification message, so as to be able to report the Qos Monitoring Reporting of the quality of service monitoring in a timely manner.

[0091] It should be noted that for the information reporting method provided in the embodiment of the present application, the execution subject can be an information reporting device, or a control module in the information reporting device for executing the information reporting method. In the embodiment of the present application, the information reporting method executed by the information reporting device is taken as an example to illustrate the information reporting device provided in the embodiment of the present application.

[0092] Figure 4 A schematic structural diagram of the information reporting device provided in the embodiment of the present application is shown, as Figure 4 shown, the information reporting device 400 includes: an information acquisition module 401 and an information reporting module 402.

[0093] The information acquisition module 401 is used to acquire target information; the information reporting module 402 is used to report the quality of service monitoring for the first edge application server or the first application function in response to the target information.

[0094] It can be seen that in the embodiment of the present application, by acquiring the target information and responding to the target information, the quality of service monitoring for the first edge application server or the first application function is reported, so as to be able to report the quality of service monitoring in a timely manner.

[0095] Based on the above embodiment, further, the information acquisition module is used to execute:

[0096] In the case of being relocated by the first edge application server or application function to the second edge application server or application function, obtain target information, where the target information is used to indicate that the data transmission between the first network device and the first edge application server or the first application function has been completed, or to indicate that the data transmission between the first network device and the second network device has been completed; there is a communication connection between the first network device and the first edge application server or the first application function, and there is a communication connection between the second network device and the second edge application server or the second application function.

[0097] Further, the information acquisition module is used to execute:

[0098] Receive an end identifier sent by the second network device, where the end identifier is used to indicate that the data transmission between the first network device and the second network device has ended.

[0099] Further, the information acquisition module is used to execute:

[0100] Receive a flow end identifier sent by the second network device, where the flow end identifier is used to indicate that the data transmission between the first network device and the first edge application server or the first application function has ended.

[0101] Further, the information acquisition module is used to execute:

[0102] Obtain the last packet notification information sent by the terminal to the first edge application server or the first application function through the application layer, where the last packet notification information is used to indicate that the terminal has sent the last data packet to the first edge application server or the first application function.

[0103] Further, the target packet header mark is carried in the last packet notification information.

[0104] Further, the information acquisition module is used to execute:

[0105] Receive the last packet notification information sent by the session management function through the N4 session management process, where the last packet notification information is sent by the terminal to the session management function through a non-access stratum message, and the last packet notification information is used to indicate that the terminal has sent the last data packet to the first edge application server or the first application function.
