[0036] It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other. To facilitate understanding of the embodiments of the present disclosure, the present disclosure 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 the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0037] In order to solve the technical problem of how to improve the accuracy of event information sent by user equipment in the prior art, the present disclosure provides an event monitoring method, which can improve the accuracy of event information sent by user equipment.

[0038] FIG1 is a flow chart of an event monitoring method according to an embodiment of the present disclosure. The present 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 the present 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 the present method, or a plurality of electronic devices can cooperate with each other to execute the present method. When the above-mentioned execution subject is software, the present method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is given here.

[0039] As shown in FIG. 1 , the method includes steps 101 to 104 .

[0040] In step 101, it is determined whether the user equipment has accessed a 5G network.

[0041] In this embodiment, the user equipment may be any device capable of connecting to a 4G network and a 5G network.

[0042] In step 102, when it is determined that the user equipment has accessed a 5G network, a first subscription request is triggered, wherein the first subscription request carries a network switching monitoring event.

[0043] 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.

[0044] In step 103, it is determined 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.

[0045] 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.

[0046] In step 104, when the user equipment performs target network switching, a second subscription request is triggered, and when event information corresponding to the second subscription request is detected, the event information is sent to the user equipment.

[0047] In this embodiment, after the user equipment switches from a 4G network to a 5G network, a second subscription request may be triggered. 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.

[0048] 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.

[0049] In some optional implementations of this embodiment, the following three steps may be used to send event information corresponding to the second subscription request to the user equipment.

[0050] In the first step, the third network element is controlled to detect event information corresponding to the second subscription request.

[0051] 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.

[0052] 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.

[0053] In the second step, the event information is stored in the third network element.

[0054] In the third step, the third network element is controlled to notify the user equipment of the event information.

[0055] It will be appreciated that in the above optional implementation, the third network element may be responsible for detecting the event information corresponding to the second subscription request and storing the event information. After receiving the UDM (Unified Data Management) subscription request, the third network element may store the subscription information and notify the user device of the event information. This improves the accuracy of sending the event information corresponding to the second subscription request to the user device.

[0056] The event monitoring method provided by the embodiment of the present disclosure 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 a 4G network to a 5G network, and then, when the user device performs a target network switch, trigger a second subscription request, and when the event information corresponding to the second subscription request is detected, send event information 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 a 4G network to a 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 a 4G network to a 5G network can be improved.

[0057] FIG2 is a flow chart of an event monitoring method according to another embodiment of the present disclosure. As shown in FIG2 , the method specifically includes steps 201 to 205 .

[0058] In step 201, it is determined whether the user equipment has accessed a 5G network.

[0059] In this embodiment, step 201 is substantially the same as step 101 in FIG. 1 and will not be described in detail here.

[0060] In step 202, when it is determined that the user equipment has accessed a 5G network, a first subscription request is triggered, wherein the first subscription request carries a network switching monitoring event.

[0061] In this embodiment, step 202 is substantially the same as step 102 in FIG. 1 and will not be described in detail here.

[0062] In step 203, the registration information of the user equipment is determined.

[0063] In this embodiment, the registration information may include location information of the user equipment.

[0064] In step 204, based on the registration information, it is determined whether the user equipment performs target network switching, wherein the target network switching indicates that the user equipment switches from a 4G network to a 5G network.

[0065] 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.

[0066] In step 205, when the user equipment performs target network switching, a second subscription request is triggered, and when event information corresponding to the second subscription request is detected, the event information is sent to the user equipment.

[0067] In this embodiment, step 205 is substantially the same as step 104 in FIG. 1 , and will not be described in detail here.

[0068] In some optional implementations of this embodiment, the following four steps may be used to determine the registration information of the user equipment.

[0069] In a first step, a location update request from a user equipment is received.

[0070] In the second step, the 4G registration information corresponding to the location update request is saved.

[0071] In the third step, a 5G registration request from the user equipment is received.

[0072] In the fourth step, the 5G registration information corresponding to the 5G registration request is saved.

[0073] On this basis, the following method can be used to determine whether the user equipment performs target network switching based on the registration information: based on the 4G registration information and the 5G registration information, determine whether the user equipment performs target network switching.

[0074] 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.

[0075] In some application scenarios of the above optional implementation manner, the following two steps can be used to determine whether the user equipment performs target network switching based on the 4G registration information and the 5G registration information.

[0076] In the first step, it is determined whether the first saving time is before the second saving time to obtain judgment information.

[0077] 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. In addition, 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.

[0078] The determination information indicates whether the first save time is before the second save time.

[0079] In the second step, 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.

[0080] 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 has switched from the 4G network to the 5G network, thereby improving the accuracy of judging whether the user equipment has switched from the 4G network to the 5G network.

[0081] In some application scenarios of the above optional implementation methods, the 4G registration information and the 5G registration information are stored in the first network element.

[0082] The first network element can 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. This corresponds to the HSS functional entity in an EPS (Evolved Packet System) network. The HSS is responsible for registration management and event monitoring in the EPS network.

[0083] On this basis, when the user equipment performs target network switching, the following two steps may also be performed.

[0084] In the first step, the first network element is controlled to send a notification message to the second network element.

[0085] The notification message carries information indicating that the user equipment has switched from a 4G network to a 5G network.

[0086] 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.

[0087] In the second step, the second network element is controlled to return a success response message to the first network element for the notification message.

[0088] 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.

[0089] In some cases of the above application scenarios, the following three steps may be used to trigger the second subscription request.

[0090] In the first step, the second network element is controlled to trigger a second subscription request.

[0091] The second subscription request carries events monitored in the 4G network.

[0092] The second network element may include a NEF.

[0093] In the second step, the second network element is controlled to send a second subscription request to the first network element.

[0094] The first network element may include an HSS and a UDM.

[0095] In the third step, 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.

[0096] The third network element may include AMF.

[0097] 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.

[0098] It should be noted that, in addition to the contents recorded above, this embodiment may also include the corresponding technical features described with reference to Figure 1, thereby realizing the technical effects of the event monitoring method shown in Figure 1. For details, please refer to the relevant description of Figure 1. For the sake of brevity, it will not be elaborated here.

[0099] The event monitoring method provided by the embodiment of the present disclosure determines whether the user equipment is switched from the 4G network to the 5G network through the registration information of the user equipment, thereby improving the accuracy of determining whether the user equipment is switched from the 4G network to the 5G network.

[0100] The embodiments of the present disclosure are exemplarily described below, but it should be noted that the embodiments of the present disclosure 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 disclosure.

[0101] 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: when the UE switches to the 5GS domain for the first time, 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, 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.

[0102] 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.

[0103] To solve the above problems, this method can adopt the following five steps.

[0104] 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).

[0105] In the second step, the UDM detects the handover status of the UE (ie the above-mentioned user equipment) and notifies the NEF.

[0106] In the third step, NEF receives that the UE state is switched to 5G, and re-triggers the subscription request (that is, the second subscription request mentioned above) to UDM.

[0107] In the fourth step, UDM receives the subscription request (that is, the second subscription request mentioned above) and forwards it to AMF.

[0108] 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.

[0109] Therefore, this method can ensure the validity of AMF subscription records.

[0110] Specifically, this method can be performed according to the following process.

[0111] Figure 3A is a structural block diagram of an event monitoring method according to an embodiment of the present disclosure. Figure 3B is a schematic diagram of network element interaction involved in an event monitoring method according to an embodiment of the present disclosure.

[0112] 3A and 3B , the following process is performed.

[0113] 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.

[0114] 2. HSS+UDM returns a success response message to MME and saves the 4G registration information.

[0115] 3. NEF triggers a subscription request to HSS+UDM through 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.

[0116] 4. HSS+UDM saves the subscription record for subsequent reporting and notification, and returns a success response to NEF.

[0117] 5. AMF triggers a registration request to HSS+UDM through the Nudm_UEContextManagement_Registration interface to perform the 5G registration process.

[0118] 6. HSS+UDM returns a success response message to AMF and saves the 5G registration information.

[0119] 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.

[0120] 8. NEF returns a success response message to HSS+UDM.

[0121] 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).

[0122] 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.

[0123] 11. AMF receives the UDM subscription request, saves the subscription information, and returns a subscription success response message to UDM.

[0124] 12. UDM returns a subscription success response message to NEF.

[0125] 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.

[0126] The event monitoring method provided by the embodiment of the present disclosure performs signaling analysis. When the 4G-5G 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 4G-5G 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, has no new attribute dependence on UDM and AMF, and the subscription data is directly obtained from the NEF, which can ensure the integrity and accuracy of the subscription data.

[0127] 4 is a schematic diagram of the structure of an event monitoring device according to an embodiment of the present disclosure, wherein the event monitoring device comprises a first determining unit 401 , a first triggering unit 402 , a second determining unit 403 , and a second triggering unit 404 .

[0128] The first determining unit 401 is configured to determine whether the user equipment accesses the 5G network.
