In the above-mentioned operator's network, the part other than the radio access network part may be referred to as the core network part.

Terminal device (terminal device), also called user equipment (user equipment, UE), is a device with wireless transceiver function, which can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; it can also be deployed on water It can also be deployed in the air (such as airplanes, balloons, and satellites). The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, an industrial control (industrial control) Wireless terminals in ), wireless terminals in self-driving, wireless terminals in remote medical, wireless terminals in smart grid, and wireless terminals in transportation safety , Wireless terminals in smart cities, wireless terminals in smart homes, etc. For ease of description, this application will use UE instead of the terminal device for description in the following.

The above-mentioned terminal equipment may establish a connection with the operator's network through an interface (such as N1, etc.) provided by the operator's network, and use services such as data and/or voice provided by the operator's network. The terminal device can also access the DN through the operator's network, and use the operator's service deployed on the DN and/or the service provided by a third party. Among them, the above-mentioned third party may be a service party other than the operator's network and terminal equipment, and may provide other services such as data and/or voice for the terminal equipment. Among them, the specific form of expression of the above-mentioned third party can be determined according to actual application scenarios, and is not limited here.

RAN is a sub-network of an operator's network, and an implementation system between service nodes and terminal equipment in the operator's network. To access the operator's network, the terminal device first passes through the RAN, and then can be connected to the service node of the operator's network through the RAN.

A DN is a network located outside the operator's network. The operator's network can access multiple DNs, and multiple services can be deployed on the DN, which can provide data and/or voice services for terminal devices. For example, DN is a private network of a smart factory. The sensors installed in the workshop of the smart factory can be terminal devices. A control server for the sensors is deployed in the DN, and the control server can provide services for the sensors. The sensor can communicate with the control server, obtain instructions from the control server, and transmit the collected sensor data to the control server according to the instructions. For another example, the DN is the internal office network of a company. The mobile phones or computers of the employees of the company can be terminal devices, and the mobile phones or computers of the employees can access the information and data resources on the internal office network of the company.

UDR must be able to have different data access authentication mechanisms for different types of data such as contract data and policy data to ensure the security of data access; UDR must be able to return and carry appropriate data for illegal servicing operations or data access requests The failure response for the reason value.

NEF network elements are mainly used to support the opening of capabilities and events.

The AF network element provides certain application layer services to the UE. When the AF provides services to the UE, it has requirements for QoS policies and charging policies (Charging) and needs to notify the network. At the same time, AF also needs application-related information fed back from the core network.

PCF network elements include policy control decision-making and flow-based charging control functions, including user subscription data management functions, policy control functions, charging policy control functions, QoS control, etc.

The NRF network element can be used to provide the network element discovery function, and provide the network element information corresponding to the network element type based on the request of other network elements. NRF also provides network element management services, such as network element registration, update, de-registration, and network element status subscription and push.

The NWDAF network element is used to provide the big data analysis information of the contracted terminal according to the request of the policy module PCF, and help the PCF optimize the strategy control; it can provide the big data analysis information according to the slice dimension. In addition, NWDAF network elements can also provide data analysis results to network elements such as AMF, SMF, NRF, AF, NEF, and OAM. Among them, the NWDAF network element can be deployed alone, or can be deployed in one with other core network elements (such as AMF, SMF, PCF, NEF, NRF, etc.).

FIG. 3 is a flowchart of a communication method provided by an embodiment of this application. As shown in FIG. 3, the method of this embodiment may include:

S301. An abnormality may occur in the first network element acquiring the terminal device.

In this embodiment, the first network element may be, for example, a data analysis network element, and the data analysis network element may be, for example, NWDAF. An abnormality may occur in the first network element acquiring the terminal device.

In the first possible implementation manner, the terminal device acquires that the terminal device may be abnormal, and then the terminal device sends first abnormality notification information to the first network element, and the first abnormality notification information is used to indicate that the terminal device may be abnormal. Correspondingly, the first network element receives the first abnormality notification information from the terminal device, and determines that the terminal device may be abnormal according to the first abnormality notification information.

Wherein, one way for the terminal device to obtain the possible abnormality of the terminal device may be: the terminal device obtains the movement track of the terminal device and/or the record of the user using the application in the terminal device, and then according to the movement track of the terminal device And/or the user uses the record of the application in the terminal device to determine that the terminal device may be abnormal. For example: the user sets the itinerary for the terminal device, such as arriving home at 23:00 at the latest, the terminal device determines the actual itinerary of the terminal device (that is, the movement trajectory of the terminal device, which is the real-time or actual movement trajectory of the terminal device) and the user settings If they are consistent, the terminal device determines that the terminal device is normal; if they are not consistent, the terminal device determines that the terminal device may be abnormal. Another example: the terminal device predicts the itinerary through a third-party APP installed on the terminal device, such as a scene intelligence mode, and then judges whether the actual itinerary is consistent with the predicted itinerary. If they are consistent, the terminal device determines that the terminal device is normal, and if they are inconsistent, the terminal device determines that the terminal device may be abnormal.

In a possible implementation manner, the first network element receives the first abnormality notification information sent from the terminal device through the control plane. One way is: the terminal device controls to send the first abnormality notification information to the third network element, and after receiving the first abnormality notification information, the third network element sends the first abnormality notification information to the first network element. For example, the terminal device controls to send a non-access stratum message to the third network element, the non-access stratum message includes the first exception notification information, and the non-access stratum message is used by the third network element to send to all The first network element sends the first abnormality notification information. Therefore, after receiving the non-access stratum message, the third network element sends the first abnormality notification information in the non-access stratum message to the first network element.

The third network element is, for example, AMF, the terminal device sends a non-access stratum message to AN, AN forwards the non-access stratum message to AMF, and then AMF sends the first abnormality notification information in the non-access stratum message to the first network element (Such as NWDAF), where the non-access stratum message is specifically a non-access stratum mobility management message.

The third network element is, for example, SMF. The terminal device sends a non-access stratum message to AN, AN sends a non-access stratum message to SMF through AMF, and then SMF sends the first exception notification information in the non-access stratum message to the first Network element (for example, NWDAF), where the non-access stratum message is specifically a non-access stratum session management message.

In a possible implementation manner, the first network element receives the first abnormality notification information sent from the terminal device through the user plane. One way is: the terminal device faces the first abnormality notification information of the fourth network element through the user, and after receiving the first abnormality notification information, the fourth network element sends the first abnormality communication information to the first network element. For example, the terminal device sends data to the fourth network element through the user. The data is, for example, uplink data. The data includes first abnormality notification information. The data is used by the fourth network element to send data to the first network element. Send the first abnormality notification information, the destination address of the data is the address of the first network element, and the fourth network element receives the data from the terminal device. If the destination address of the data is the address of the first network element, then The fourth network element sends the information in the data (that is, the first abnormality notification information) to the first network element. Therefore, after receiving the data, the fourth network element sends the first abnormal communication information in the data to the first network element.

The fourth network element is, for example, UPF, the terminal device sends data to AN, AN forwards the data to UPF, and then UPF sends the first abnormal notification information in the data to the first network element (for example, NWDAF).

The fourth network element is, for example, SMF. The terminal device sends data to AN, and AN sends data to SMF. Then SMF sends the first exception notification information in the data to SMF, and SMF finally sends the first exception notification information to the first network element. (E.g. NWDAF).

In a possible implementation manner, the data may also be sent by the terminal device to the fourth network element through a preset session or a preset quality of service flow identifier (QoS Flow Identifier, QFI), and the terminal device through the preset session Suppose that the session or preset QFI sends data to the fourth network element, and the fourth network element receives the data and sends the information in the data (that is, the first abnormality notification information) to the fourth network element according to whether the data is transmitted through the preset session or preset QFI The first network element. For example, the fourth network element is UPF, and the terminal device establishes preset session 1. The terminal device sends data to UPF through preset session 1, and carries the first exception notification information. When UPF receives the data, it sends the data to SMF. The SMF sends the first abnormal notification information to the first network element. For another example, the fourth network element is UPF, SMF assigns the preset QFI=1, and the terminal device sends data to the UPF through the preset QFI=1, that is, the QFI corresponding to the data is QFI=1, and the data carries the first abnormality notification information When the UPF receives the data carrying QFI=1, it sends the first exception notification in the data to the SMF, and the SMF sends the first exception notification information to the first network element.

In the second possible implementation manner, the first network element determines the terminal mobility analysis result (UE Mobility Analytics) of the terminal device and/or the terminal communication analysis result (UE Communication Analytics) of the terminal device. The terminal equipment may be abnormal. How the first network element obtains the terminal mobility analysis result of the terminal device and how to obtain the terminal communication analysis result of the terminal device can be referred to the description in the related technology, which will not be repeated here. According to the terminal mobility analysis result of the terminal device, the first network element determines that the mobility of the terminal device is abnormal. The first network element determines that the terminal device service is abnormal based on the terminal communication analysis result of the terminal device. If there is an abnormality in sexual and/or terminal equipment business, it is determined that the terminal equipment may be abnormal.

In a third possible implementation manner, the first network element receives the mobility abnormality indication information of the terminal device and/or the service abnormality indication information of the terminal device, and according to the mobility abnormality indication information and/or The service abnormality indication information determines that the terminal device may be abnormal. For example, the first network element may send the terminal mobility analysis result of the terminal device to other network elements (such as AMF). If the AMF determines that the mobility of the terminal device is abnormal based on the terminal mobility analysis result, the AMF sends the A network element sends abnormal mobility indication information. For example, the first network element may send the terminal communication analysis result of the terminal device to other network elements (for example, SMF). If the SMF determines that the terminal device’s service is abnormal according to the terminal communication analysis result, the SMF will send it to the first network element Send service exception indication information. Then, the first network element determines that the terminal device may be abnormal according to the mobility abnormality indication information from the AMF and/or the service abnormality indication information from the SMF.

Among them, the process of obtaining the mobile analysis result of the terminal is: the NWDAF network element receives the mobile analysis request from the application function network element (AF) or the network function network element (network function, NF), and sends the mobile management network element ( Access and Mobility Management Function (AMF) sends a subscription request so that NWDAF receives terminal location information (including time and location information) from AMF, and analyzes and obtains the mobility analysis result of the terminal device based on the location information. The terminal communication analysis result acquisition process is: NWDAF receives a communication analysis request from the NF, and sends a subscription request to AF and UPF according to the communication analysis request to obtain communication information of the terminal device (such as the start time of the user interface interaction of the terminal device, and the user of the terminal device) The end time of the interface interaction, the size of the uplink data packet during the user interface interaction of the terminal device, and the size of the downlink data packet during the user interface interaction of the terminal device), and analyze the terminal communication analysis result of the terminal device according to the communication information of the terminal device.

In a possible implementation manner, after the first network element determines that the terminal device may be abnormal through the above-mentioned second possible implementation manner or the third possible implementation manner, the first network element sends the second network element to the terminal device. Abnormal notification information, the second abnormal notification information is used to indicate that the terminal device may be abnormal. Correspondingly, the terminal device receives the second abnormality notification information sent by the first network element, and determines that the terminal device may be abnormal according to the second abnormality notification information.

S302. The first network element receives information related to the terminal device.

In this embodiment, the terminal device receives information related to the terminal device, and the information includes at least one of the following: information about the environment in which the terminal device is located, and information about the terminal device. Among them, the information of the terminal device is acquired or collected by the terminal device itself, and the information of the environment in which the terminal device is located is acquired by devices other than the terminal device.

In a possible implementation, if the terminal device sends the terminal device information to the first network element and also sends the terminal device first abnormality notification information to the first network element, the terminal device can send the same message to the first network element Send the information of the terminal device and the first abnormality notification information.

In a possible implementation manner, the first network element receives information about the environment in which the terminal device is located sent by other devices, and the information about the environment in which the terminal device is located refers to information about the surrounding environment where the terminal device is located. For example: the first network element sends an environmental information request to other devices, and the environmental information request is used to request information about the environment in which the terminal device is located. Accordingly, after receiving the environmental information request, the other device sends the terminal device to the first network element Information about your environment. The environmental information request may include the location of the terminal device, and may also include the identification of the terminal device.

Other devices can be other terminal devices besides the terminal device. Other terminal devices are located within a certain distance of the above-mentioned terminal device. Other terminal devices are smart city terminal devices, such as smart light pole signs on the road, smart Cameras, etc., are not limited in this embodiment. Information about the environment in which the terminal device is located, for example, includes at least one of the following: location, image, video, and audio. The location can be the location where it is collected by other terminal devices. The image, video, and audio are also images collected by other terminal devices. , Video, audio.

The other devices can also be other network elements except the first network element. The other network elements receive the information of the terminal device's environment collected by other terminal devices from other terminal devices, and then the other network elements determine the information about the environment in which the terminal device is located. The information is sent to the first network element. Other network elements are, for example, smart city platforms. It should be noted that the first network element may also send environmental information requests to other devices through the smart city platform. The first network element may query network elements such as NRF, UDM, or UDR based on the area where the terminal device is located for addresses or identification information of other network elements (for example, AMF, SMF, UPF, AF, NEF) in the area.

In a possible implementation manner, the first network element receives information about the environment in which the terminal device is located from other devices, which may be implemented in the following manner: the first network element receives and sends the first environmental information acquisition request to the smart city platform, Carrying the location information of the terminal device, the smart city platform sends a second environment information acquisition request to other devices near the location of the terminal device, and other devices return an environment information acquisition response to the smart city platform, carrying information about the environment in which the terminal device is located, and then the smart city The platform sends information about the environment in which the terminal device is located to the first network element. It should be noted that the first environmental information acquisition request and the second environmental information acquisition request are different messages or the same message, which is not limited in the embodiment of the present application.

S303. The first network element determines the status of the terminal device according to the information related to the terminal device.

In this embodiment, the first network element determines the status of the terminal device according to the above-mentioned information related to the terminal device, and the status of the terminal device is a normal condition or an abnormal condition.

S304. The first network element sends the status of the terminal device to the second network element.

In this embodiment, after determining the condition of the terminal device, the first network element sends the condition of the terminal device to the second network element, and the condition is used by the second network element to determine a processing strategy corresponding to the condition. Among them, the second network element is, for example, PCF or AF or network management or AMF or SMF, which is not limited in this embodiment.

Correspondingly, the second network element receives the status of the terminal device sent by the first network element.

S305. The second network element determines a processing strategy corresponding to the situation according to the situation of the terminal device.

In this embodiment, after receiving the status of the terminal device sent by the first network element, the second network element determines a processing strategy corresponding to the status according to the status of the terminal device.

In this embodiment, the first network element acquires possible abnormalities in the terminal device and receives information related to the terminal device. The information includes at least one of the following: information about the environment in which the terminal device is located, and information about the terminal device. Then, according to the information related to the terminal device, determine the status of the terminal device and send the status of the terminal device to a second network element, so that the second network element determines a processing strategy according to the status of the terminal device. The first network element of this embodiment can accurately determine the actual status of the terminal device based on the above-mentioned information related to the terminal device. For example, the status of the terminal device can reflect whether the user is currently in a dangerous situation, so that the second network element can determine the corresponding Processing strategy, through the processing strategy can ensure the safety of users as much as possible.

In some embodiments, if the condition of the terminal device is a normal condition, the processing strategy includes triggering to release an early warning of the terminal device. For example: if the terminal device acquires that the terminal device may be abnormal, the terminal device will set an early warning. If the processing strategy determined by the second network element includes triggering the terminal device to release the warning, the second network element will notify the terminal device to cancel the warning.

If the condition of the terminal device is the first abnormal level condition, the processing strategy includes notifying the emergency contact of the user of the terminal device, or notifying a security point within a preset range of the location of the terminal device. For example: if the condition of the terminal device is the first abnormal level condition, the second network element informs the emergency contact of the user of the terminal device so that the emergency contact can contact the user as soon as possible whether it is dangerous, or the second network Yuan notifies the security point within the preset range of the location of the terminal device, so that the security personnel of the security point can check whether there is any danger in the surroundings.

If the condition of the terminal device is the second abnormal level condition, the processing strategy includes reporting to the police, that is, the alarm center platform (AF). For example: if the condition of the terminal device is the second abnormal level condition, the second network element sends an alarm request to the alarm center platform. The alarm request includes at least one of the following: the identification, location, and time of the terminal device to request the police Alarm is issued to ensure the safety of users.

In a possible implementation manner, after S303, that is, after the first network element determines the status of the terminal device according to the information related to the terminal device, the first network element directly sends the status of the terminal device to Alarm Center Platform (AF). The alarm center platform makes corresponding operations based on the terminal's status. If the terminal device is in a normal state, the alarm center platform has no operation; if the terminal device is in an abnormal state, the alarm center platform initiates an alarm and arranges for an alarm.

The following example describes the solution of the embodiment of the application. The terminal device is the UE, the first network element is NWDAF, the second network element is PCF, the third network element is AMF, the fourth network element is SMF, and the other devices are smart cities. Take the smart terminal managed by the platform as an example.

For scenario 1, when the UE predicts an abnormality, it controls sending an abnormality notification to NWDAF. FIG. 4 is a flowchart of a communication method provided by another embodiment of this application. As shown in FIG. 4, the method of this embodiment may include:

Step 1. UE abnormal prediction/analysis.

The UE may perform abnormality prediction/analysis in the following ways: itinerary abnormality judgment and/or service abnormality judgment. (1) The UE sets the itinerary, such as arriving home at 23:00 at the latest. (2) The UE predicts the user's itinerary through a third-party APP, such as a scenario intelligence mode, such as predicting that the user will arrive home at 23:00 at the latest. The UE judges whether the actual itinerary is consistent with the set itinerary or the predicted itinerary through (1) or (2). If they are consistent, the UE confirms that there is no abnormality or there is no abnormal travel; (3) The UE sets up the service, such as a conference call at 22:00. (4) The UE records or predicts the business behavior of the UE through a third-party APP, such as a scene smart mode or a smart calendar, for example, it is predicted that the UE will conduct a conference call at 22:00. The UE judges whether the actual service is consistent with the set service or predicted service through (3) or (4). If they are consistent, the UE confirms that there is no abnormality or no service abnormality.

In a possible implementation manner, before step 2 is performed, the following operation may also be performed: the UE prompts the user to confirm whether it is abnormal by vibrating or ringing. The user may have three operations: (A) Confirm OK, that is, confirm that there is no abnormality; (B) Confirm abnormality; (C) No operation. For operation A, the alarm function is released, that is, there is no need to perform subsequent operations; for operation B or C, the UE can start positioning, start recording, start the camera, etc. to obtain the UE's location, audio, and video.

Step 2. If the UE determines that the UE may be abnormal, it sends an abnormal notification to the NWDAF through control, which is described as follows:

The first step: the UE sends a NAS message to the AMF, and the NAS message contains an exception notification. The anomaly notification includes an abnormal result, and the anomaly notification may also include information about the UE obtained by the UE, such as location, audio recording, video recording, battery power, and so on. The abnormal result may be the first abnormal notification information in the foregoing embodiments.

Step 2: AMF sends an exception notification to NWDAF.

In a possible implementation manner, the UE determines that the UE may be abnormal, which means that the user corresponding to the UE may be abnormal. In the following cases, the UE determines that the UE may be abnormal: when the user receives the vibration or ringing prompt in step 1, the user confirms the abnormality, or the user does not perform any operation; or, the UE determines the itinerary and/or business abnormality according to step 1.

Step 3. NWDAF confirms the abnormality according to the abnormal notification to determine the status of the UE. Among them, the condition of the UE may be: the UE condition is normal, and the UE condition is abnormal.

In a possible implementation, NWDAF can be combined with a smart city platform to determine the status of the UE. The details are shown in steps 4-6:

Step 4. NWDAF sends a first environmental information acquisition request to the smart city platform, carrying the location (ULI) of the UE.

Step 5. After receiving the first environment information acquisition request, the smart city platform sends an AF request to the PCF. The AF request carries indication information, and the indication information is used to trigger the smart terminal to report environment information (that is, information about the environment where the UE is located).

Step 6. The PCF generates a second environmental information acquisition request (also referred to as a policy) according to the AF request, and sends the second environmental information acquisition request to the smart terminal.

In a possible implementation manner, the second environmental information acquisition request includes a smart terminal identifier, and the second environmental information acquisition request may further include the address of the NWDAF.

The smart terminal refers to environmental variables near the UE, such as smart light poles, smart cameras, etc.

It should be noted that there are two ways for the PCF to send the second environment information acquisition request to the smart terminal:

The PCF sends the second environment information acquisition request to the SMF, the SMF is forwarded to the AMF, and the AMF sends the second environment information acquisition request to the smart terminal through the NAS message. or

The PCF sends the second environment information acquisition request to the AMF, and the AMF sends the second environment information acquisition request to the smart terminal through the NAS message.

In a possible implementation, the smart city platform described in step 5 to step 6 sends instructions to the smart terminal through PCF, AMF or SMF so that the smart terminal can report environmental information. Replace it with the following method: the smart city platform sends instructions directly to the smart terminal, for example, the smart city platform sends instructions to the smart terminal through the application layer.

Step 7. After receiving the second environment information acquisition request, the smart terminal sends the environment information collected by the smart terminal (that is, the information of the environment where the UE is located) through the user to the smart city platform.

Step 8. The smart city platform forwards the received environmental information to NWDAF.

In a possible implementation, the smart terminal described in step 7 to step 8 sends environmental information to NWDAF through the smart city platform, which is an implementation method. This implementation method can also be replaced by the following method: the smart terminal according to step 6 The NWDAF address obtained in, sends environmental information directly to NWDAF.

Step 9. NWDAF combines the abnormal notification in step 2 and the environmental information in step 8 to confirm the abnormality and determine the status of the UE.

Step 10. NWDAF sends the status of the UE to the PCF.

Step 11. The PCF determines the corresponding processing strategy according to the status of the UE. details as follows:

The status of the UE is safe: the PCF determines that the alarm is released.

The status of the UE is abnormal at the first level: the PCF determines to notify the emergency contact or nearby security points to check.

The status of the UE is a second-level abnormality: the PCF determines to replace the UE to alert the alarm center.

Step 12. When the UE's condition is a second-level abnormality, the PCF sends an alarm request to the alarm center platform (AF), carrying the UE's identity, location, time and other information.

Therefore, when the UE determines that the UE may be abnormal, it sends an abnormal notification to the NWDAF through control; NWDAF can also perform abnormal confirmation according to the abnormal notification, and in a possible implementation manner, according to the environmental information near the UE, and determine the status of the UE; and The status of the UE is sent to the PCF, and the PCF decides whether to perform an alarm operation according to the status of the UE. In this way, the personal safety of the UE user can be protected reasonably and timely, and the user can be prevented from being injured when the user cannot perform an alarm operation at a dangerous moment.

For scenario 2, when the UE predicts an abnormality, the user sends an abnormal notification to the NWDAF. FIG. 5 is a flowchart of a communication method provided by another embodiment of this application. As shown in FIG. 5, the method of this embodiment may include:

Establish a user plane connection between the UE and the network.

In a possible implementation manner, when the UE starts the abnormal prediction APP, the UE initiates a session establishment process to establish a user plane connection between the UE and the network. In a possible implementation manner, when the UE registers to the network, it initiates a session establishment procedure to establish a user plane connection between the UE and the network. Among them, the established session is a preset session, which is used to transmit the abnormal notification of the UE.

In a possible implementation manner, the abnormal notification of the UE may also be transmitted in a manner of preset QFI.

The process of establishing a preset session or preset QFI can be described as:

Step 1. The UE sends a NAS message to the AMF, carrying a session establishment request. Among them, the session establishment request includes the PDU session ID; the NAS message includes DNN and S-NSSAI.

Among them, the PDU session ID is used to identify the session; the DNN is used to identify the network accessed by the session; and the S-NSSAI is used to identify the slice accessed by the session.

In a possible implementation, when the UE's abnormal notification is transmitted through the preset session mode, the session establishment request also carries indication information. The indication information is used to indicate that the session is a preset session, that is, the session cannot provide other services. service. A preset session can also become a dedicated session.

In a possible implementation, when the UE's abnormal notification is transmitted in the preset QFI mode, the session establishment request also carries indication information, which is used to request the SMF to assign a preset service flow ID (QoS Flow ID, QFI) . The preset QFI can also become a dedicated QFI.

Step 2. The AMF selects the SMF and sends a session management context creation request to the SMF, carrying the session establishment request, DNN, and S-NSSAI.

Step 3. After receiving the session establishment request, the SMF selects the UPF according to the session establishment request and the policy from the PCF and/or local, and the SMF sends forwarding rules to the UPF.

In a possible implementation manner, when the UE’s abnormal notification is transmitted through the preset QFI mode, the SMF is based on the indication information carried by the UE in step 1, or the UE’s subscription data, or the local configuration policy, or the policy from the PCF, Assign a preset QFI.

The forwarding rule is used to indicate the UPF: (1) When the UE's abnormal notification is transmitted through the preset session mode, the forwarding rule instructs the UPF to send the received data of the session to the NWDAF. In a possible implementation manner, the forwarding rule can also be described as: instructing the UPF to send the received data of the session to the SMF, and the SMF to forward the data to the NWDAF. (2) When the abnormal notification of the UE is transmitted through the preset QFI mode, the forwarding rule is used to instruct the UPF to send the received data corresponding to the QFI to the NWDAF. In a possible implementation, the forwarding rule can also be described as: instructing the UPF to send the received data corresponding to the QFI to the SMF, and the SMF to forward the data to the NWDAF.

Step 4. SMF establishes a user plane connection between UE, RAN, and UPF.

This step is consistent with the description in the prior art, and will not be repeated in this embodiment. In this process, the SMF sends a session establishment acceptance message to the UE, indicating that the session establishment is successful.

In a possible implementation manner, the session establishment accept message includes the NWDAF address, which is used by the UE to set the destination address corresponding to the abnormal notification as the NWDAF address.

In a possible implementation manner, the UE may also obtain the NWDAF address through configuration.

In a possible implementation manner, the UE may also obtain the NWDAF address through a Domain Name System (DNS) query method. Specifically, when the UE starts the abnormal prediction APP, it first sends a DNS query request to the DNS server, carrying the domain name corresponding to the abnormal prediction APP; the DNS server returns the IP address corresponding to the domain name, that is, the NWDAF address.

Through the above steps 1-4, the user plane connection between the UE and the network is established. The user plane connection corresponds to a preset session or corresponds to a preset QFI.

Step 5. UE abnormal prediction/analysis.

Reference may be made to the related description of step 1 in the embodiment shown in FIG. 4.

Step 6. If the UE determines that the UE may be abnormal, it sends an abnormal notification to the NWDAF through the user.

Specifically: the terminal sends the exception notification to the RAN, and the RAN sends the UPF. The UPF sends the uplink data, that is, the abnormal notification, to the NWDAF according to the forwarding rule in step 3, or sends it to the SMF, and then the SMF to the NWDAF.

In a possible implementation manner, when the UE obtains the NWDAF address through step 4, the destination address corresponding to the abnormal notification is the NWDAF address.

Steps 7 to 16 are similar to steps 3 to 12 in the embodiment shown in FIG. 4, and will not be repeated here.

Therefore, when the UE detects an abnormality, the user sends an abnormality notification to the NWDAF; NWDAF can also confirm the abnormality according to the environmental information near the UE according to the abnormality notification, and in a possible implementation manner; and send the abnormality confirmation result to PCF, the PCF decides whether to perform an alarm operation based on the abnormal confirmation result. Realize reasonable and timely protection of the personal safety of UE users, and prevent users from being injured when they are unable to perform alarm operations at dangerous moments.

For scenario three, when NWDAF predicts an abnormality, the terminal is triggered to report the information collected by the terminal. FIG. 6 is a flowchart of a communication method provided by another embodiment of this application. As shown in FIG. 6, the method in this embodiment may include:

NWDAF performs abnormal prediction on the terminal. The prediction method is shown in steps 1 to 4:

Step 1. NWDAF obtains UE mobility information (UE mobility information) from AMF, and obtains UE communication information (UE communication information) from AF and/or SMF. NWDAF obtains UE mobility analysis (UE mobility analysis) according to UE mobility information; obtains UE communication analysis (UE communication analytics) according to UE communication information.

Example-1: NWDAF predicts that the UE will arrive home at 23:00.

Example-2: NWDAF predicts that the UE will access the game at 23:20.

Step 2a. The NWDAF sends the UE mobility analysis to the AMF, and the AMF monitors whether the UE's mobility is abnormal. When the AMF detects abnormal mobility, it sends abnormal mobility indication information (for example, abnormal travel notice) to NWDAF.

Step 2b. NWDAF sends the UE communication analysis to the SMF, and the SMF monitors whether the UE's service is abnormal. When the SMF detects service abnormality, it sends service abnormality indication information (for example, service abnormality notification) to NWDAF.

Example-1: The UE accesses the game at 23:20, but the service is interrupted suddenly, and the game is not re-accessed within a certain period of time, the SMF can determine that the UE is in an abnormal service.

Step 3. NWDAF performs abnormal prediction on the UE. Specifically, when the NWDAF judges that the terminal mobility and the service are abnormal according to the mobility abnormality indication information and the service abnormality indication information, or one of the two is abnormal, the NWDAF determines that the UE is abnormal.

Step 4. NWDAF sends an early warning confirmation request to the UE through AMF. This early warning confirmation request is also the second abnormal notification information mentioned in the foregoing embodiment.

In a possible implementation manner, NWDAF sends an early warning confirmation request to the UE through SMF and AMF.

Step 5. The UE receives the early warning confirmation request and triggers the opening of functions such as positioning, recording, and camera.

In a possible implementation manner, before the UE starts the collection, the UE may also prompt the user to confirm the abnormality through vibration or ringing. There are 3 results for user abnormal confirmation: (1) No abnormality; (2) Abnormality; (3) No operation. For (1) there is no abnormality, the UE may not start the collection process.

Step 6. The UE sends the UE information obtained in step 5 to NWDAF.

Among them, the UE information includes: UE location, image, video, audio, etc. In a possible implementation manner, the UE information also includes the time and power of the UE.

In a possible implementation manner, the UE sends an exception notification to the NWDAF, and the exception notification includes the information of the terminal device.

It should be noted that there are three ways for the UE to send terminal-capable device information to NWDAF: (1) Send to NWDAF via the control plane, refer to the description in the embodiment shown in Figure 4; (2) Send via the user plane To UPF, UPF is sent to NWDAF according to forwarding rules or sent to SMF and then forwarded to NWDAF according to forwarding rules. Refer to the description in the embodiment shown in Figure 5; (3) The UE sets the destination address of the uplink data to the address of NWDAF, Therefore, the UE sends the uplink data, that is, the abnormal notification to the UPF, and the UPF directly sends it to the NWDAF, which can refer to the description in the embodiment shown in FIG. 5.

In a possible implementation manner, the abnormal confirmation result of the user in step 5 is further included.

Step 7 to step 15 are similar to step 4 to step 12 in the embodiment shown in FIG. 4, and will not be repeated here.

Therefore, NWDAF can confirm the abnormality according to the abnormal notification, and in a possible implementation manner, according to the environmental information near the UE; and send the abnormal confirmation result to the PCF, and the PCF decides whether to perform an alarm operation according to the abnormal confirmation result. Realize reasonable and timely protection of the personal safety of UE users, and prevent users from being injured when they are unable to perform alarm operations at critical moments.

It should be noted that the above-mentioned first network element may be a separate network element, or may also be set in other core network network elements. The foregoing second network element may be a separate network location name, or may also be set in other core network network elements. In the embodiment of the present application, the data analysis network element may include a data training unit and a data analysis unit. The data training unit and the data analysis unit can be integrated in the same unit or can be independent units. The data analysis unit can implement the sending, receiving and related processing functions in the above-mentioned first network element.

It should be noted that any of the foregoing embodiments can be implemented separately, or can be implemented in any combination of at least two of the foregoing embodiments, which is not limited.
