[0001] The present application relates to the field of computer technology, and in particular to an event monitoring method, device, electronic device, and storage medium. Background Art

[0002] Currently, in the 4G to 5G network handover scenario, when the UE (User Equipment) switches from 4G to 5G, in some cases, the AMF (Access and Mobility Management Function) side does not have subscription information or the subscription information is inaccurate, and the subscription information needs to be resynchronized to the AMF. For example, when a user switches from 4G to 5G for the first time, or when a user switches from 5G to 4G and the AMF clears the local subscription record, the AMF side may not have the time information corresponding to the subscription request.

[0089] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the above technologies, methods, and equipment should be considered part of the specification.

[0090] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0091] It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other. To facilitate understanding of the embodiments of this application, the application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0092] In order to solve the technical problem in the prior art of how to improve the accuracy of event information sent by user equipment, the present application provides an event monitoring method, which can improve the accuracy of event information sent by user equipment.

[0093] Figure 1 A flow chart of an event monitoring method provided in an embodiment of the present application. This method can be applied to one or more electronic devices such as smart phones, laptops, desktop computers, portable computers, servers, etc. In addition, the execution subject of this method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the above-mentioned execution subject is software, this method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0094] like Figure 1 As shown, the method specifically includes:

[0095] Step 101: Determine whether the user equipment is connected to the 5G network.

[0096] In this embodiment, the user equipment may be any device capable of connecting to a 4G network and a 5G network.

[0097] Step 102: When it is determined that the user equipment accesses the 5G network, trigger a first subscription request, wherein the first subscription request carries a network switching monitoring event.

[0098] In this embodiment, once the user equipment accesses the 5G network, a first subscription request carrying a network switching (CN type change) monitoring event can be triggered to monitor whether the user equipment has performed a network switch.

[0099] Step 103: Determine whether the user equipment performs target network switching, wherein the target network switching indicates that the user equipment switches from the 4G network to the 5G network.

[0100] In this embodiment, since the subscription request carrying the network switching monitoring event (ie, the first subscription request) is triggered in the above step 102, it can be determined whether the user equipment is switched from the 4G network to the 5G network.

[0101] Step 104: When the user equipment switches to the target network, trigger a second subscription request, and send event information corresponding to the second subscription request to the user equipment.

[0102] In this embodiment, after the user equipment switches from the 4G network to the 5G network, the second subscription request may be retriggered. Thereafter, if event information corresponding to the second subscription request is detected, the event information corresponding to the second subscription request may be sent to the user equipment.

[0103] In addition, the above steps 101 to 104 can be performed by one or more network elements in the 5G core network. In this embodiment, the specific network element performing the above steps 101 to 104 is not limited. In practice, the network element performing the above steps can be determined according to specific needs.

[0104] In some optional implementations of this embodiment, the event information corresponding to the second subscription request may be sent to the user equipment in the following manner:

[0105] The first step is to control the third network element to detect event information corresponding to the second subscription request.

[0106] The third network element may include an AMF (Access and Mobility Management Function). As an example, the third network element may be responsible for detecting and reporting some events.

[0107] In addition, the above-mentioned third network element can support UEs with different mobility management requirements. The AMF network element can perform the following main tasks: non-access stratum (NAS) signaling termination, NAS signaling security, access stratum security control, core network inter-node signaling for mobility between 3GPP access networks, idle mode UE reachability (including control and execution of paging retransmissions), registration area management, support for intra-system and inter-system mobility, access authentication, access authorization, etc.

[0108] The second step is to save the event information in the third network element.

[0109] The third step is to control the third network element to detect an event (ie, event information corresponding to the second subscription request), and to send the event notification information to the user equipment.

[0110] It is understood that in the above optional implementation, the third network element can be responsible for detecting the event information corresponding to the second subscription request and saving the corresponding event information. After receiving the UDM (Unified Data Management) subscription request, the third network element can save the subscription information and send the event notification information to the user equipment. This improves the accuracy of sending the event information corresponding to the second subscription request to the user equipment.

[0111] The event monitoring method provided in the embodiment of the present application can determine whether the user device is connected to the 5G network, and then, when it is determined that the user device is connected to the 5G network, trigger a first subscription request, wherein the first subscription request carries a network switching monitoring event, and then determine whether the user device performs a target network switch, wherein the target network switch indicates that the user device switches from the 4G network to the 5G network, and then, when the user device performs the target network switch, trigger a second subscription request, and send event information corresponding to the second subscription request to the user device. Thus, when the user device is connected to the 5G network, the network switching event can be monitored, and then, if it is monitored that the user device switches from the 4G network to the 5G network, the subscription request is re-triggered through the 5G network, and then the event information corresponding to the re-triggered subscription request can be sent to the user device. In this way, the accuracy of sending event information to the user device in the scenario where the user device switches from the 4G network to the 5G network can be improved.

[0112] Figure 2 A flowchart of another event monitoring method provided in an embodiment of the present application.

[0113] like Figure 2 As shown, the method specifically includes:

[0114] Step 201: Determine whether the user equipment is connected to the 5G network.

[0115] In this embodiment, step 201 and Figure 1 Step 101 in the corresponding embodiment is basically the same and will not be described again here.

[0116] Step 202: When it is determined that the user equipment accesses the 5G network, trigger a first subscription request, wherein the first subscription request carries a network switching monitoring event.

[0117] In this embodiment, step 202 and Figure 1 Step 102 in the corresponding embodiment is basically the same and will not be described again here.

[0118] Step 203: Determine the registration information of the user equipment.

[0119] In this embodiment, the registration information may include location information of the user equipment.

[0120] Step 204: Based on the registration information, determine whether the user equipment performs a target network switch, wherein the target network switch indicates that the user equipment switches from the 4G network to the 5G network.

[0121] In this embodiment, the location information of the user device included in the registration information can be used to determine whether the network connected to the user device has switched from a 4G network to a 5G network, thereby determining whether the user device has switched from a 4G network to the 5G network.

[0122] Step 205: When the user equipment switches to the target network, trigger a second subscription request, and send event information corresponding to the second subscription request to the user equipment.

[0123] In this embodiment, step 205 and Figure 1 Step 104 in the corresponding embodiment is basically the same and will not be described again here.

[0124] In some optional implementations of this embodiment, the following method may be used to determine the registration information of the user equipment:

[0125] The first step is to receive a location update request from the user equipment.

[0126] The second step is to save the 4G registration information corresponding to the location update request.

[0127] The third step is to receive a 5G registration request from the user equipment.

[0128] The fourth step is to save the 5G registration information corresponding to the 5G registration request.

[0129] On this basis, the following method can be used to determine whether the user equipment performs target network switching based on the registration information:

[0130] Based on the 4G registration information and the 5G registration information, it is determined whether the user equipment performs a target network handover.

[0131] It can be understood that in the above optional implementation method, the UE can initiate an Update_Location_Request request (also known as a location update request) to the HSS (Home Subscriber Server) + UDM through the MME (Mobility Management Entity). After that, the HSS + UDM returns a success response message to the MME and saves the 4G registration information. Subsequently, the AMF can trigger a registration request to the HSS + UDM through the Nudm_UEContextManagement_Registration interface. The HSS + UDM returns a success response message to the AMF and saves the 5G registration information. Finally, the HSS + UDM determines whether the UE switches from 4G to 5G based on the locally saved registration information status. In this way, it is possible to determine whether the user equipment is switched from the 4G network to the 5G network based on the 4G registration information and the 5G registration information, thereby improving the accuracy of determining whether the user equipment is switched from the 4G network to the 5G network.

[0132] In some application scenarios of the above optional implementation manner, the following manner may be adopted to determine whether the user equipment performs target network handover based on the 4G registration information and the 5G registration information:

[0133] First, it is determined whether the first saving time is before the second saving time to obtain judgment information.

[0134] The first saving time is the saving time of the 4G registration information, and the second saving time is the saving time of the 5G registration information. Furthermore, there is no saving time of other registration information (including 4G registration information and 5G registration information) between the first saving time and the second saving time.

[0135] The determination information indicates whether the first save time is before the second save time.

[0136] Afterwards, when the determination information indicates that the first saving time is before the second saving time, it is determined that the user equipment performs target network switching.

[0137] It can be understood that in the above application scenario, by comparing the saving time of the 4G registration information and the saving time of the 5G registration information, it is determined whether the user equipment is switched from the 4G network to the 5G network, thereby improving the accuracy of judging whether the user equipment is switched from the 4G network to the 5G network.

[0138] In some application scenarios of the above optional implementation manner, the 4G registration information and the 5G registration information are stored by the first network element.

[0139] The first network element may include the HSS and UDM, also known as the converged network element. The UDM is responsible for registration management, forwarding event monitoring subscriptions, and detecting and reporting some subscription events. It corresponds to the HSS functional entity in the EPS (Evolved Packet System) network. The HSS is responsible for registration management and event monitoring in the EPS network.

[0140] On this basis, when the user equipment performs the target network handover, the following steps may also be performed:

[0141] First, the first network element is controlled to send a notification message to the second network element.

[0142] The notification message carries information indicating that the user equipment has switched from a 4G network to a 5G network.

[0143] The second network element may include a Subscriber Data Model (NEF). For example, the second network element may be responsible for providing an open interface and open data to external vendors (e.g., AF), such as terminal status, location, periodic update time, device-card binding status, policy control, and QoS (Quality of Service) capabilities. AF refers to various application layer services.

[0144] Afterwards, the second network element is controlled to return a success response message to the first network element for the notification message.

[0145] It can be understood that in the above application scenario, the first network element (such as UDM) can trigger a notification message to the second network element (such as NEF) through the network element interface (such as Nudm_EventExposure_Notify), which carries a notification message that the UE status is switched from 4G to 5G. In this way, in the form of a notification message, it is more timely to judge whether the user equipment is switched from the 4G network to the 5G network.

[0146] In some cases of the above application scenarios, the second subscription request can be triggered in the following manner:

[0147] First, the second network element is controlled to trigger a second subscription request.

[0148] The second subscription request carries the events monitored in the 4G network.

[0149] The second network element may include a NEF.

[0150] Afterwards, the second network element is controlled to send a second subscription request to the first network element.

[0151] The first network element may include an HSS and a UDM.

[0152] Then, after the first network element forwards the second subscription request to the third network element, a success response message returned by the third network element in response to the second subscription request is received.

[0153] Among them, the third network element may include AMF.

[0154] It can be understood that in the above case, the second network element (such as NEF) can determine that the subscription request (that is, the above-mentioned second subscription request) needs to be re-triggered based on the UE status carried in the notification from the first network element (such as HSS, UDM) that it is switched from 4G to 5G. The second network element obtains all locally stored subscription information and re-triggers the subscription request to the first network element. The first network element determines that the subscription event carried by the second network element can be detected by a third network element. The first network element forwards the subscription request to the third network element and saves the subscription information.

[0155] It should be noted that, in addition to the above contents, this embodiment may also include Figure 1 The corresponding technical features described in the corresponding embodiments are realized Figure 1 For details on the technical effects of the event monitoring method shown, please refer to Figure 1 For the sake of brevity, the relevant description will not be repeated here.

[0156] The event monitoring method provided in the embodiment of the present application determines whether the user device is switched from the 4G network to the 5G network through the registration information of the user device, thereby improving the accuracy of determining whether the user device is switched from the 4G network to the 5G network.

[0157] The following is an illustrative description of the embodiments of the present application, but it should be noted that the embodiments of the present application may have the features described below, but the following description does not constitute a limitation on the scope of protection of the embodiments of the present application.

[0158] Currently, when a UE moves from EPS to 5GS (5G System), the existing solution usually needs to ensure that complete subscription information exists on the UDM side. Scenarios where there is no complete information on the UDM side are not considered. Scenarios where there is no complete subscription information include: the UE switches to the 5GS domain for the first time and the UDM has no subscription information, or the subscription records stored on the UDM side are aged and cleared during the switching process. In addition, the existing solution requires both UDM and AMF to support the new attributes before it can take effect, which makes the implementation complex. For scenarios where only some sites support the new attributes, the problem cannot be solved. In addition, the existing solution requires the UDM side to save complete subscription information (that is, the event information corresponding to the subscription request), and the UDM storage overhead is large. For some subscription information that is maintained through message interaction between AMF and NEF (such as the maximum number of reports (maxNumOfReports information), the UDM cannot perceive the changes. Therefore, if the UDM local data synchronization is used directly, there is a risk of inaccurate event information.

[0159] In practice, with the increasing automation of IoT devices, monitoring of these devices is becoming increasingly common. Operators need to quickly detect device status changes and respond promptly to them to improve the user experience, such as tracking vehicle connection anomalies. IoT devices may experience handovers between 4G and 5G networks during use, ensuring that event monitoring functions are not affected during these handovers.

[0160] To solve the above problems, this method can adopt the following steps:

[0161] In the first step, NEF (Subscriber Data Model, network capability exposure function, also known as the second network element) subscribes to the CN type change event (also known as the network switching monitoring event) from UDM (Unified Data Management, also known as the first network element).

[0162] In the second step, the UDM detects the handover status of the UE (ie the above-mentioned user equipment) and notifies the NEF.

[0163] In the third step, NEF receives the UE status switch to 5G and re-triggers the subscription request (that is, the second subscription request mentioned above) to UDM.

[0164] In the fourth step, UDM receives the subscription request (that is, the second subscription request mentioned above) and forwards it to AMF.

[0165] In the fifth step, AMF (ie, the third network element mentioned above) saves the latest subscription information (ie, the event information mentioned above) and detects corresponding event changes.

[0166] Therefore, this method can ensure the validity of AMF subscription records.

[0167] Specifically, this method can be performed according to the following process:

[0168] Please refer to Figure 3A and Figure 3B . Please refer to Figure 3A , Figure 3A A structural block diagram of an event monitoring method provided in an embodiment of the present application. Figure 3B A schematic diagram of network element interactions involved in an event monitoring method provided in an embodiment of the present application.

[0169] exist Figure 3B 1. The UE initiates an Update_Location_Request request (location update request) to the HSS+UDM (converged network element) through the MME to perform the 4G registration process.

[0170] 2. HSS+UDM returns a success response message to MME and saves the 4G registration information.

[0171] 3. NEF triggers a subscription request to HSS+UDM via the Nudm_EventExposure_Subscribe interface, carrying the monitoring event CN type change. The Nudm_EventExposure_Subscribe interface is used to provide the AMF event subscription function.

[0172] 4. HSS+UDM saves the subscription record for subsequent reporting and notification, and returns a success response to NEF.

[0173] 5. AMF triggers a registration request to HSS+UDM through the Nudm_UEContextManagement_Registration interface to perform the 5G registration process.

[0174] 6. HSS+UDM returns a success response message to AMF and saves the 5G registration information.

[0175] 7. HSS+UDM determines whether the UE switches from 4G to 5G based on the locally saved registration information status. UDM triggers a notification message to NEF through the Nudm_EventExposure_Notify interface, carrying the UE status of switching from 4G to 5G.

[0176] 8. NEF returns a success response message to HSS+UDM.

[0177] 9. NEF determines that the user equipment has switched from 4G to 5G based on the UE status carried in the HSS+UDM notification, and then re-triggers the subscription request. NEF obtains all locally saved subscription information and re-triggers the UDM subscription request (that is, the second subscription request mentioned above).

[0178] 10. UDM determines that NEF carries the subscription event, which is detected by AMF. UDM forwards the subscription request to AMF and saves the subscription information.

[0179] 11. AMF receives the UDM subscription request, saves the subscription information, and returns a subscription success response message to UDM.

[0180] 12. UDM returns a subscription success response message to NEF.

[0181] It should be noted that, in addition to the contents recorded above, this embodiment may also include the technical features described in the above embodiments, thereby achieving the technical effects of the event monitoring method shown above. Please refer to the above description for details. For the sake of brevity, no further details will be given here.

[0182] The event monitoring method provided in the embodiment of the present application performs signaling analysis. When the 45G network is switched, the NEF re-triggers the subscription request after receiving the CN type change notification. In this way, the validity and integrity of the AMF subscription record in the 45G switching scenario can be improved, and the complexity of obtaining the AMF subscription record can be simplified. The accuracy of monitoring events is improved to better meet user needs. In addition, this method is implemented based on the original subscription and notification process, and has no new attribute dependence on UDM and AMF. The subscription data is obtained directly from the NEF, which can ensure the integrity and accuracy of the subscription data.
