First, application scenarios applicable to the present application will be described. The method and the device can be applied to the technical field of intrusion monitoring.
With the development of technology, once only the effect existing in the film and television is gradually realized and civilian, such as indoor monitoring systems. Home protection is of increasing concern and more people choose to deploy indoor intrusion monitoring systems in the home. However, currently, generally, an indoor security monitoring device mainly adopts video monitoring, the video monitoring device transmits a shot video to a terminal used by a user through a wireless network, and the user watches the video by himself to identify whether strangers invade the home. The intrusion monitoring method has low efficiency and has great potential safety hazard.
Based on the above, the embodiment of the application provides an indoor intrusion monitoring method based on a 5G core network, which can enable the intrusion monitoring efficiency to be higher and the reliability of the monitoring service to be stronger through the indoor intrusion monitoring service bound by the 5G core network.
Referring to fig. 1, fig. 1 is a flowchart of an indoor intrusion monitoring method based on a 5G core network according to an embodiment of the present application. As shown in fig. 1, an indoor intrusion monitoring method provided in an embodiment of the present application is applied to an indoor intrusion monitoring system based on a 5G core network, where the indoor intrusion monitoring system includes an application function device, a plurality of user pre-devices associated with the application function device, and a 5G core device, and the indoor intrusion monitoring method includes:
And S101, the application function device responds to the specific operation of the user on the intrusion monitoring function, and sends device information to the 5G core device so that the 5G core device can verify the device information.
It should be noted that, the application function device refers to a network element AF (The Application Function) in the 5G core network, and refers to various APPs that may directly or indirectly interact with the 5G network. According to the embodiment provided by the application function device can be an APP (application program) which can be used for realizing indoor intrusion monitoring in intelligent network equipment used by a user. The intelligent network device is a smart phone, a tablet, a bracelet, or the like, and the application is not particularly limited. The specific operation refers to an operation of the user on the application function device for the intrusion monitoring function, for example, the specific operation may be a selection operation or a click operation of the user on the application function device for the intrusion monitoring function, and the application is not particularly limited.
Here, the application function device is mainly used for interaction with a user. Before using the intrusion monitoring function, a user can install an intelligent home intrusion monitoring application, namely an application function device, on the intelligent network device, and register and bind the application function device through a telephone number. And then, the application function equipment is used for pairing with each user front-end equipment by scanning a two-dimensional code on the user front-end equipment or manually inputting an IP address of the user front-end equipment, so that equipment information of each user front-end equipment paired with the application function equipment can be recorded. For the above step S101, in implementation, the application function device responds to the specific operation of the user on the intrusion monitoring function, and sends the device information to the 5G core device, so that the 5G core device can verify the validity of the intelligent network device on which the application function device is installed according to the device information sent by the application function device.
Specifically, the device information includes first identification information of an intelligent network device in which the application function device is installed and second identification information of a plurality of user pre-devices associated with the application function device. Here, the first identification information is identification information of the intelligent network device on which the application function device is installed, for example, the first identification information may be an IP address or a mobile phone number of the user side, which is not specifically limited in this application. The second identification information is the second identification information of the plurality of user pre-devices associated with the application function device, for example, the second identification information may be an IP address of each user pre-device, etc., which is not specifically limited in this application. Each user head-end has a specific IP address to facilitate differentiation and control.
S102, after the verification of the device information by the 5G core device is passed, sending data receiving requests to a plurality of user front-end devices.
The data receiving request refers to a request sent by the 5G core device to the user front end device to collect data sent by the user front end device.
Here, the 5G core device is mainly used for performing indoor intrusion monitoring according to data sent by the user front-end device. For the above step S102, in the implementation, after receiving the application function device, the 5G core device verifies the device information sent by the application function device, and after the verification is passed, sends a data receiving request to the plurality of user front-end devices.
And S103, the user front-end equipment sends real-time channel state information to the 5G core equipment according to a preset time interval based on the data receiving request.
In the field of wireless communication, channel state information (CSI, channel State Information) refers to channel properties of a communication link. It describes the attenuation factor of the signal on each transmission path, i.e. the value of each element in the channel gain matrix H, such as signal Scattering (Scattering), environmental attenuation (coding, multipath fading or shadowing fading), distance attenuation (power decay of distance), etc. The CSI may adapt the communication system to the current channel conditions, providing a guarantee for high reliability and high rate communication in a multi-antenna system. The customer premises equipment (Customer premises equipment, CPE) refers to a mobile signal access device that receives mobile signals and forwards them out as wireless signals. The preset time interval refers to a preset time interval in which the user front-end equipment sends real-time channel state information to the 5G core equipment in real time, for example, the preset time interval may be 3 seconds, which is not specifically limited in this application. In particular implementations, a user may set a time interval for a user-premises equipment to transmit real-time channel state information by applying a functional device.
Here, the user arranges the user head-end in the room, and in order to reduce the error of the signal data, a plurality of user head-end devices may be arranged in the room to completely and sufficiently cover each corner of the room. The user front-end equipment is mainly used for sensing indoor channel state information and forwarding the channel state information to the 5G core equipment. For the above step S103, in a specific implementation, for each of the plurality of user head-end equipments, after receiving the data receiving request sent by the 5G core equipment, the real-time channel state information is sent to the 5G core equipment at a preset time interval. Here, according to the embodiment provided by the application, the user front-end device is used as a transmitting device and a receiving device of signals, the user front-end device is placed at four corners of a relatively closed room to serve as the transmitting and receiving devices of signals, when the device works, the user front-end device transmits and receives channel state information between each other, the channel state information can be affected by a plurality of obstacles in an actual indoor propagation environment, and can reach a receiver along a plurality of paths including refraction and reflection, wherein signals on different paths can undergo distortion such as attenuation and time delay of different degrees, and in a relatively static environment, the data of the channel state information can keep relatively stable, and the channel state information can be collected at preset time intervals by the user front-end device and uploaded to the 5G core device.
And S104, the 5G core equipment receives the real-time channel state information sent by the plurality of user front-end equipment and analyzes the real-time channel state information so as to monitor indoor intrusion.
For the step S104, in implementation, the 5G core device receives the real-time channel state information sent by the plurality of user pre-devices, and analyzes the received real-time channel state information to perform indoor intrusion monitoring.
Specifically, the 5G core device includes a network opening device and a network analysis device; the indoor intrusion monitoring method further comprises the following steps:
step 201: the network opening device receives the device information sent by the application function device, verifies the first identification information in the device information, and sends a plurality of second identification information in the device information to the network analysis device after verification is passed.
It should be noted that, the network opening device refers to a network element NEF (The Network Exposure Function, network opening function) in the 5G core network, and the main function of this network function is capability opening, that is, outputting the capability of the 5G network to an external network, such as outputting location information of a terminal to the outside. According to the embodiment provided by the application, the network opening device is mainly used for authorizing the application function device and subscribing the indoor intrusion monitoring function for the user.
For the above step 201, in implementation, the network opening device receives the device information sent by the application function device, verifies the first identification information of the intelligent network device installed with the application function device in the device information, and verifies whether the first identification information is registered with the indoor intrusion monitoring function or not. And after the verification is passed, second identification information of a plurality of user prepositions associated with the application function device in the device information is sent to the network analysis device, so that the network analysis device can determine the plurality of user prepositions associated with the application function device according to the second identification information.
Step 202: the network analysis equipment sends the data receiving request to a plurality of user prepositions corresponding to the second identification information according to the second identification information, receives the real-time channel state information sent by the user prepositions, and analyzes the real-time channel state information to perform indoor intrusion monitoring.
It should be noted that, the network analysis device refers to a network element NWDAF (Network Data Analytics Function, network data analysis function) in the 5G core network, and the main function of this network function is to implement network analysis, where the NWDAF may collect network data from each network function and perform analysis, and provide the analysis result as a service to other network functions.
For the step 202, when the verification of the first identification information by the network analysis device is passed, the network analysis device sends a data receiving request to a plurality of user front-end devices corresponding to the plurality of second identification information according to the plurality of second identification information, receives the real-time channel state information sent by the plurality of user front-end devices, and analyzes the real-time channel state information to perform indoor intrusion monitoring.
Specifically, before the network analysis device analyzes the real-time channel state information, the indoor intrusion monitoring method further includes:
for each user front-end equipment, the network analysis equipment receives historical channel state information sent by the user front-end equipment in a historical time period and establishes a plurality of average vector fluctuation models of different time ranges of the user front-end equipment in the historical time period based on the historical channel state information.
Here, the history period may be a day or a week or the like in the past, and the present application is not particularly limited. The history time ranges refer to respective time periods in the history time period. For example, when the historical time period is a certain day of the history, the time range may be each hour of the day; when the historical time period is a certain week of the history, the time range may be each day of the week. The average vector fluctuation model is an average CSI vector fluctuation model generated from all the historical channel state information received in the historical time range.
Here, the examples of the history period and the history time range are merely examples, and in practice, the history period and the history time range are not limited to the above examples.
For the above steps, in implementation, before indoor intrusion monitoring, the network analysis device needs to analyze normal channel state information under the condition of no personnel intrusion. For each user front-end equipment arranged indoors, the network analysis equipment receives historical channel state information sent by the user front-end equipment in a historical time period and establishes a plurality of average vector fluctuation models of different time ranges of the user front-end equipment in the historical time period based on the historical channel state information. As an example, the network analysis device receives historical channel state information transmitted by the user head-end over a certain day of the history, then divides the historical time range into a plurality of time ranges, each time range may represent one hour of the day, and then establishes, for each time range, an average vector fluctuation model corresponding to the time range based on the historical channel state information in the historical time range.
Specifically, for the step 202, the network analysis device receives the real-time channel state information sent by the plurality of user pre-devices, analyzes the real-time channel state information, so as to perform indoor intrusion monitoring, and includes:
Step 2021: for each user head end, determining a current time at which the user head end generated the real-time channel state information.
Step 2022: and determining a target average vector fluctuation model corresponding to the current time from the plurality of average vector fluctuation models corresponding to the user front-end equipment based on the current time.
For the above steps 2021-2022, in implementation, for each user-premises equipment, the current time at which the user-premises equipment generates real-time channel state information is first determined. And then determining a target average vector fluctuation model corresponding to the current time from a plurality of average vector fluctuation models corresponding to the user front-end equipment based on the current time. Continuing with the above embodiment, for example, the time range corresponding to each average vector fluctuation model may represent one hour in the day, and when the current time of the user front-end device generating real-time channel state information is 10:30, it is determined that the time range corresponding to the current time is 10:00-11:00, so that an average vector fluctuation model with the time range of 10:00-11:00 is determined as the target average vector fluctuation model in a plurality of average vector fluctuation models.
Step 2023: and comparing the received real-time channel state information sent by the user front-end equipment with the target usual vector fluctuation model to determine a channel state information fluctuation value.
Step 2024: and comparing the channel state information fluctuation value with a preset average fluctuation threshold, and judging that the indoor intrusion exists currently when the channel state information fluctuation value is larger than or equal to the average fluctuation threshold.
The average fluctuation threshold is preset to determine whether a person intrudes into the current room or not and the fluctuation threshold of the channel state information in the normal range. The channel state information fluctuation value refers to the fluctuation condition between the received real-time channel state information and a normal target usual vector fluctuation model.
For the above steps 2023 to 2024, in the implementation, after the target average vector waveform model is obtained in step b, the received real-time channel state information sent by the user front-end device is compared with the target normal vector fluctuation model, so as to determine the channel state information fluctuation value. And comparing the fluctuation value of the channel state information with a preset average fluctuation threshold, and judging that the indoor intrusion exists currently when the fluctuation value of the channel state information is larger than or equal to the average fluctuation threshold.
Thus, according to the indoor intrusion monitoring method provided by the embodiment of the application, one or more pieces of user prepositive equipment supporting the sensing function are arranged in each independent space in the room, channel state information is affected by indoor articles or mobile individuals, and behaviors of indoor objects or people can be detected by combining analysis and acquisition of sensing information such as Doppler frequency shift, amplitude change and phase change, so that personal privacy is protected, and household cost is saved. And the signal change data acquired through intelligent analysis is compared with the historical data, and when an intruder intrudes into the space, the channel state information acquired in real time is compared with the historical channel state information under normal conditions, so that the existence of the intruder is detected.
Further, the 5G core device further includes a network decision device, and when the network analysis device determines that there is an intrusion in the current room, the indoor intrusion monitoring method further includes:
i: and when the network analysis equipment judges that the current indoor intrusion exists, the network analysis equipment sends the channel state information fluctuation numerical value to the network decision-making equipment.
II: and the network decision device determines an intrusion early warning strategy based on the channel state information fluctuation value and sends the intrusion early warning strategy to the application function device.
III: and the application function equipment responds to the specific operation of the user on the intrusion early warning strategy, generates a strategy execution request and sends the strategy execution request to a plurality of user front-end equipment.
IV: and the user front-end equipment executes the corresponding intrusion early warning strategy based on the strategy execution request.
It should be noted that, the intrusion early warning policy refers to an early warning policy determined by the network decision-making device and executed by the user front-end device. For example, the intrusion alert policy may be an audio alert policy, a public security alert policy, etc., which is not specifically limited in this application. The sound alarm strategy can be to alarm the intruder by making sound through the front-end equipment of the user; the police alarm strategy can collect image and video of an intruder through the front-end equipment of the user and then send the image and video to the police early warning system for alarm.
Here, the network analysis device is mainly used for determining an intrusion early warning policy for the user according to the fluctuation condition of the current channel state information. Aiming at the steps I-IV, when the network analysis equipment judges that the current indoor intrusion exists in the concrete implementation, the fluctuation value of the channel state information is sent to the network decision-making equipment. And the network decision device determines an intrusion early warning strategy based on the channel state information fluctuation value and sends the intrusion early warning strategy to the application function device. At this time, the intrusion early warning policy is displayed in the application function device, and the user can select to execute the intrusion early warning policy in the application function device. When the user selects to execute the intrusion early warning strategy, the application function equipment responds to the specific operation of the user on the intrusion early warning strategy, generates a strategy execution request and sends the strategy execution request to the user front-end equipment.
