[0073] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of embodiments of this disclosure.

[0074] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments of this disclosure. The singular forms “a” and “the” as used in this disclosure are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to any one or all possible combinations of one or more of the associated listed items.

[0075] It should be understood that although the terms "first," "second," "third," etc., may be used to describe various elements in embodiments of this disclosure, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of embodiments of this disclosure, "first element" may also be referred to as "second element," and similarly, "second element" may also be referred to as "first element." Depending on the context, the word "if," as used herein, may be interpreted as "when," "in response to a determination," or "when," or "in the event of a determination."

[0076] Furthermore, in the description of the embodiments of this disclosure, "and / or" is merely a way of describing the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in the description of the embodiments of this disclosure, "multiple" can refer to two or more.

[0077] With the development of AI technology, numerous industries are becoming increasingly intelligent, and perception technology has become a crucial technological foundation. Radar-based perception technologies are widely used in intelligent transportation, autonomous driving, and people counting. Currently, radar-based perception technologies primarily rely on dedicated radar equipment. However, dedicated radar equipment suffers from drawbacks such as high cost and inflexible deployment, thus limiting its use to specific scenarios.

[0078] With the continuous development and integration of wireless technologies and sensing methods, wireless sensing technology has become a research hotspot. Wireless sensing technology can be combined with communication technologies such as 5G mobile communication to provide sensing services based on communication systems. In particular, due to the large number and wide distribution of access network functional entities and terminal devices, they have become the primary providers of sensing services. In some scenarios, access network devices can be used to provide sensing services, such as detecting animal or object intrusions on highways and sensing weather conditions.

[0079] Currently, precipitation monitoring is typically achieved using specialized precipitation monitoring equipment (e.g., rain gauges). To monitor precipitation in a region, a monitoring network is often deployed within that region. This network comprises a large number of precipitation monitoring devices. Because specialized precipitation monitoring equipment is expensive, deploying such a network requires significant financial investment, and the scale of such deployment is limited.

[0080] Based on the continuously developing wireless sensing technology, access network functional entities can be considered to replace dedicated precipitation monitoring equipment for precipitation monitoring. However, among related technologies, there is no solution for precipitation monitoring based on mobile networks.

[0081] Therefore, how to provide sensing services for precipitation monitoring based on mobile networks is an urgent problem to be solved.

[0082] Figure 1 This is a schematic diagram of a precipitation monitoring scenario based on sensing services in an embodiment of this disclosure. Figure 1 The scenario shown includes a requesting device 101, a sensing application function (SAF) 102, and an access network function 103.

[0083] The requesting device 101 can be a device used to request precipitation monitoring services. For example, the requesting device 101 can be a site device installed at a meteorological bureau or weather station. Alternatively, the requesting device 101 can be a user's terminal device.

[0084] SAF 102 is used to manage wireless sensing services such as precipitation monitoring services. In particular, SAF 102 can be a function owned or trusted by a service provider and certified and authorized by the requesting device 101.

[0085] Access network function 103 has wireless sensing capabilities, particularly for wirelessly sensing precipitation, i.e., processing precipitation monitoring services. Specifically, the wireless signal transmitted by the antenna of access network function 103 is attenuated as it propagates through the atmosphere due to the presence of atmospheric components. In rainy weather, in addition to the aforementioned attenuation, there is further attenuation caused by rainwater. Therefore, the propagation path attenuation of the wireless signal increases. In particular, the degree of attenuation caused by rainwater (or rainwater attenuation) depends on the size and distribution of water droplets. Thus, precipitation can be obtained by quantifying and modeling the measured values ​​of the wireless signal. For example, access network function 103 can be a base station device, such as a gNB, eNB, etc.

[0086] exist Figure 1 In the scenario shown, to obtain precipitation information for a certain location / area, the requesting device 101 can send a request to SAF 102 to request precipitation monitoring services. After receiving the request, SAF 102 can instruct the access network function 103 located at that location / area to perform wireless sensing to achieve precipitation monitoring.

[0087] exist Figure 1In this configuration, SAF 102 is deployed within the core network 104. However, it should be noted that SAF 102 can be located either inside or outside the core network 104. In the former case, SAF 102 can be a network function deployed by the operator. In this case, SAF 102 can be a core network function. In the latter case, SAF 102 can be a network function deployed by the service provider. In this case, SAF 102 can be a non-core network function and communicates with the core network 104 through a pre-defined communication interface.

[0088] also, Figure 1 Only one access network function 103 is shown in the diagram. It is understood that in practical applications, there may be multiple access network functions 103 that provide sensing services.

[0089] To provide wireless sensing services, embodiments of this disclosure provide a communication system. Figure 2 This is a schematic diagram of the structure of a communication system according to an embodiment of this disclosure. Figure 2 As shown, the communication system 200 described above may include access network functions and core network functions, which can be the access network functions and core network functions of any generation of communication system; for example, taking a 5G network as an example, the communication system 200 may include a 5G access network (AN) and a 5G core network (5GC). In the subsequent embodiments of this disclosure, a 5G network system is used as an example for description; of course, those skilled in the art will understand that the technical solutions of this disclosure can be used in any generation of communication system, including but not limited to 5G communication systems. For example, the 5G access network may include a next-generation radio access network (NG-RAN) 201. The NG-RAN 201 communicates with the terminal device 202 through a Uu interface.

[0090] The 5G core network 203 may include: access and mobility management function (AMF) 2031, user plane function (UPF) 2032, session management function (SMF) 2033, policy control function (PCF) 2034, unified data management (UDM) 2035, etc.

[0091] The sensing application function (SAF) 204 can reside within the 5G core network 203, meaning SAF 204 can be a core network function (which can be referred to as the first core network function) within the 5G core network 203, and is connected to the PCF 2034 within the 5G core network 203. In some cases, SAF 204 can also reside outside the 5G core network 203, meaning SAF 204 can be a network function in the 5G communication system, and is connected to the UPF 2032 within the 5G core network 203.

[0092] The sensing requester device 205 is located outside the 5G core network 203 and is communicatively connected to the SAF 204. It should be noted that this communication connection can be based on an Internet protocol or implemented in other ways. In one embodiment, the communication connection can be established based on Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol over Secure Socket Layer (HTTPS). In another embodiment, the communication connection can be established based on Session Initialization Protocol (SIP). To implement the above communication connection, an interface can be deployed between the SAF 204 and the sensing requester device 205, or other methods can be used. The interface deployed between the sensing requester device 205 and the SAF 204 can be any communication interface in a cellular mobile network. In one example, an interface can be deployed between the SAF 204 and the sensing requester device 205; this interface can be a communication interface defined or to be defined by the 5G communication system and its future evolution versions.

[0093] In the embodiments of this disclosure, the communication system may also include other network functions, which are not specifically limited in this disclosure.

[0094] It should be noted that the aforementioned network functions can also be described as network function entities, network elements, network function components, network function modules, network devices, etc. Similarly, the aforementioned core network functions can be described as core network function entities, core network elements, core network function components, core network function modules, core network devices, etc.

[0095] In the aforementioned communication system 200, terminal device 202 can access the 5G core network 203 through 3GPP (3rd Generation Partnership Project) technology. Specifically, terminal device 202 can access the 5G core network 203 through 3GPP access network equipment.

[0097] PCF 2034 has policy control functions, mainly responsible for policy decisions related to session and service flow billing policies, quality of service (QoS) bandwidth guarantees and policies. In this architecture, PCF 2034 connected to AMF 2031 and SMF 2033 can correspond to AM PCF (PCF for access and mobility control) and SM PCF (PCF for session management), respectively. In actual deployment scenarios, AM PCF and SM PCF may not be the same PCF entity.

[0098] SMF 2033 has session management functions, mainly including session management, execution of control policies issued by PCF 2034, selection of UPF 2032, and allocation of Internet Protocol (IP) addresses for terminal devices 202.

[0099] AMF 2031 has access and mobility management functions, mainly performing mobility management, access authentication / authorization, and other functions. In addition, it is also responsible for transmitting user policies between terminal device 202 and PCF 2034.

[0100] UPF 2032 is a user plane function entity that serves as an interface with the data network, performing functions such as user plane (UP) data forwarding, session / flow-based billing and statistics, and bandwidth limiting.

[0117] In S301, gNB sends a registration request to SAF.

[0118] The registration request can be sent from gNB to SAF in the form of a registration request message.

[0119] In one embodiment, the registration request message may carry the gNB's sensing capability information. The sensing capability information indicates the gNB's ability to perform wireless sensing. For example, the sensing capability information may include indication information indicating whether the gNB supports precipitation monitoring. In other words, the sensing capability information may indicate that the gNB supports precipitation monitoring; or, the sensing capability information may indicate that the gNB does not support precipitation monitoring. As another example, the sensing capability information may also include the gNB's wireless sensing parameters for precipitation monitoring. These wireless sensing parameters may include at least one of the following: sensing distance, sensing value range, and sensing accuracy.

[0120] The sensing distance can be related to the length of the propagation path of the wireless signal from the gNB to the gNB. Generally, the greater the sensing distance, the longer the propagation path; conversely, the smaller the sensing distance, the shorter the propagation path. Understandably, a longer propagation path allows the monitored values ​​to be closer to the true values ​​than a shorter one, resulting in more accurate sensing data.

[0121] The sensing range can be defined as the range of precipitation values ​​that the gNB can detect. For example, the sensing range could be from 0 to infinity. Understandably, due to the limitations of the gNB's antenna transmission power, excessive precipitation can cause significant path attenuation, potentially resulting in the gNB being unable to obtain data due to insufficient signal strength. Therefore, the sensing range typically has an upper limit.

[0122] Sensing accuracy refers to the precision with which the gNB can detect precipitation. It's understandable that sensing accuracy can be related to factors such as transmission power and receiver performance. For example, sensing accuracy could be 0.1 mm / day, 0.5 mm / day, or 1 mm / day.

[0123] In one embodiment, the registration request message may carry identification information of the gNB. This identification information is used to identify the gNB.

[0124] It is understood that the gNB can send a registration request to the SAF in several ways. In the first way, the gNB can send the registration request to the SAF based on the SAF's IP address. In the second way, the gNB can send the registration request to the SAF through the AMF (i.e., the second core network function). It should be noted that the gNB can also send the registration request to the SAF in other ways, and this disclosure does not specifically limit these methods.

[0125] In S302, SAF sends a registration accept to gNB.

[0126] In S301, after receiving a registration request from the site, SAF completes the registration of gNB.

[0127] Specifically, during the registration process of gNB by SAF, SAF can obtain the identification information and / or sensing capability information of gNB from the received registration request message, and can save the identification information and / or sensing capability information of gNB.

[0128] After completing the registration with the gNB, the SAF can send a registration acceptance message to the gNB. This registration acceptance message indicates that the gNB registration is complete.

[0129] Corresponding to the gNB sending a registration request to the SAF in S301, the SAF can send a registration acceptance to the gNB in ​​several ways. In the first way, the SAF can send the registration acceptance to the gNB based on the gNB's IP address. In the second way, the SAF can send the registration acceptance to the gNB via the AMF. It should be noted that the SAF can also send the registration acceptance to the gNB in ​​other ways, and this embodiment does not specifically limit these methods.

[0130] It is understandable that the registration request message sent by the gNB in ​​S301 may not carry the gNB's awareness capability information. Instead, after the gNB registers with the SAF, the gNB sends a reporting message to the SAF. This reporting message carries the gNB's awareness capability information.

[0131] Similarly, the gNB can send reporting messages to the SAF in several ways. In the first way, the gNB can send the reporting message to the SAF based on the SAF's IP address. In the second way, the gNB can send the reporting message to the SAF through the AMF. It should be noted that the gNB can also send reporting messages to the SAF in other ways, and this embodiment does not specifically limit these methods.

[0132] In S303, the site sends a sensing request to the SAF.

[0133] When a station needs to obtain precipitation information at a specific location, it can send a sensing request to the SAF. The sensing request can be sent by the station to the SAF in the form of a sensing request message (also known as the first message).

[0134] Understandably, the perception request message carries an event trigger parameter for the precipitation monitoring service. This event trigger parameter is used to indicate the event that triggers the reporting of perception data from the precipitation monitoring service.

[0135] In one embodiment, the event triggering parameter may include at least one of the following: a reporting period and a precipitation threshold. The reporting period can represent the period at which the gNB reports the sensed data. It is understood that the reporting period can be set according to actual needs. For example, the reporting period can be 10 minutes, 30 minutes, 1 hour, 2 hours, or any other duration. The precipitation threshold can be a predetermined value reached by the precipitation sensed by the gNB.

[0136] In one embodiment, when the event trigger parameter is the reporting period, the reporting event that triggers the gNB to report sensing data can be the arrival of the reporting period. For example, when the reporting period is 30 minutes, the gNB performs wireless sensing and reports sensing data every 30 minutes. In one embodiment, the reporting period can be a single period. In this case, the reporting period in the event trigger parameter can be a fixed value. In one embodiment, the reporting period can be a variable period. In this case, the reporting period in the event trigger parameter can be complete time indication information. For example, the reporting period can be in the form of multiple alternating durations, such as 5 minutes, 10 minutes, 5 minutes, 10 minutes, etc. Another example is that the reporting period can be in the form of gradually increasing durations, such as 1 minute, 2 minutes, 4 minutes, 8 minutes, etc.

[0137] In one embodiment, when the event triggering parameter is a precipitation threshold, the event that triggers the gNB to report the sensed data can be that the precipitation sensed by the gNB reaches the precipitation threshold. It is understood that the precipitation threshold can include one or more values. For example, the precipitation threshold could be 100 mm / day.

[0138] It is understood that, in one embodiment, the sensing request message may also carry at least one of the following: site identification information, sensing location information, and sensing time information. The site identification information is used to identify the site. The sensing location information is used to indicate the location where the sensing service is processed. The sensing time information is used to indicate the time when the sensing service is processed.

[0139] In one embodiment, the perceived location information can represent a geographic location. For example, the perceived location information can be the coordinate information of that geographic location in a positioning system. It is understood that the positioning system can be a Global Positioning System (GPS), Galileo satellite navigation system, BeiDou navigation satellite system, GLONASS, Quasi-Zenith Satellite System (QZSS), etc. If the location represented by the perceived location information is a location point, then the perceived location information can be a pair of coordinate values ​​corresponding to that location point (e.g., including longitude and latitude coordinate values). If the location represented by the perceived location information is a location area, then the perceived location information can be multiple pairs of coordinate values ​​corresponding to multiple location points within that location area. In another embodiment, the perceived location information can represent an administrative region location. In this case, the perceived location information can take at least one of the following forms: postal code, administrative region identifier or name, etc.

[0140] The sensing time information is used to represent the time taken to process the sensing service. This processing time may include at least one of the following: start time, end time, and duration. For example, the processing time may include both start and end times. Alternatively, the processing time may include both start and duration. Another example is that the processing time may only include the end time. Yet another example is that the processing time may only include the duration.

[0141] In one embodiment, the sensing request message may also carry at least one of the following: range requirement information and accuracy requirement information. The range requirement information may indicate the numerical range of precipitation monitoring that the station requires to be implemented. The accuracy requirement information may indicate the accuracy range of precipitation monitoring that the station requires to be implemented.

[0142] It should be noted that the perception request message may also carry other information, but this embodiment does not specifically limit this.

[0143] In S304, the SAF sends a sensing request to the gNB.

[0144] After receiving the perception request in S303, the SAF sends the perception request to the gNB.

[0145] In one embodiment, the SAF sending a sensing request to the gNB can be achieved through the following process: the SAF determines the AMF and sends a sensing request to the determined AMF; the AMF determines the gNB and sends a sensing request to the determined gNB.

[0146] In one example, the SAF can determine the AMF based on the sensing location information carried in the sensing request message. For example, the AMF should meet the following conditions: the coverage of at least one gNB connected to the AMF covers the location represented by the sensing location information, and / or, the distance between at least one gNB connected to the AMF and the location represented by the sensing location information is the closest, or less than or equal to a preset distance. In this case, the SAF can determine the AMF that meets the above conditions based on the sensing location information. It should be noted that in the embodiments of this disclosure, "coverage" includes both complete coverage and partial coverage (i.e., partial overlap).

[0147] It is understood that the SAF can store and maintain relevant information about gNBs supporting precipitation monitoring services, such as gNB identification information, gNB sensing capability information, and gNB location information. In this case, the SAF can identify the gNB based on this relevant information and the obtained sensing location information. Then, the SAF can determine the AMF based on the relevant information of the gNB. In one embodiment, the SAF can obtain relevant information about the gNB from other functions in the core network based on the sensing location information, and then determine the AMF. In another embodiment, the SAF can obtain relevant information about the AMF from other functions in the core network based on the sensing location information, thereby directly determining the AMF.

[0148] In one example, the SAF can send a sensing request to the AMF, and the sensing request can include event triggering parameters. In another example, the sensing request can also include the gNB's identification information. In yet another example, the sensing request can also include sensing location information.

[0149] In one example, after receiving a sensing request from the SAF, the AMF can obtain event triggering parameters from the sensing request. The AMF can then determine the gNB. In one example, if the sensing request carries gNB identification information, the AMF can directly determine the gNB corresponding to the identification information. In another example, if the sensing request carries sensing location information, the AMF can determine the gNB based on the sensing location information. In this case, the gNB should meet the following conditions: the gNB's coverage area covers the location indicated by the sensing service information, and / or at least one gNB connected to the AMF is closest to that location, or less than or equal to a preset distance. In this case, the AMF can determine the gNB that meets the above conditions based on the sensing location information. In one embodiment, the second gNB can be all gNBs connected to the AMF.

[0150] In one example, the AMF can send a sensing request to a specific gNB, and the sensing request can carry event triggering parameters.

[0151] Understandably, in addition to sensing location information, SAF can also consider range requirement information and / or accuracy requirement information carried in the sensing request message when determining the gNB. Specifically, SAF can compare the range requirement information and / or accuracy requirement information carried in the sensing request message with the sensing value range and / or sensing accuracy corresponding to the gNB determined based on the sensing location information to determine the gNB that meets the range requirement and / or accuracy requirement.

[0152] In one embodiment, the sensing request may also carry sensing time information.

[0153] It should be noted that the perception requests sent by the aforementioned sites to the SAF, and the perception requests sent by the SAF to the gNB, can be collectively referred to as perception requests, and are sent in the form of perception request messages (also known as second messages).

[0154] In S305, gNB sends a sensing response to SAF.

[0155] Upon receiving a sensing request in S304, the gNB determines to provide precipitation monitoring services corresponding to the sensing request. Therefore, the gNB can send a sensing response to the SAF to indicate that it is providing precipitation monitoring services.

[0156] In one embodiment, the sensing response can also be used to instruct the gNB to begin wireless sensing for precipitation monitoring.

[0157] In S306, SAF sends a sensing response to the site.

[0158] After receiving the sensing response in S305, the SAF sends a sensing response to the site. The sensing response sent by the SAF indicates that it will provide quantity monitoring services.

[0159] In S307, the gNB performs wireless sensing.

[0160] In particular, after determining in S304 that precipitation monitoring services are to be provided, gNB can process precipitation monitoring services based on sensing requests.

[0161] In one embodiment, after receiving a sensing request, the gNB can directly begin wireless sensing of precipitation based on the sensing request.

[0162] In one embodiment, when the sensing request carries sensing time information, the gNB can wirelessly sense precipitation based on the sensing time information.

[0163] Understandably, gNBs can obtain precipitation data through wireless sensing.

[0164] In S308, the gNB sends (or reports) sensing data to the SAF.

[0165] In one embodiment, since the sensing request carries event triggering parameters, the gNB can perform wireless sensing based on the event triggering parameters. For example, if the event triggering parameters include a reporting period, the gNB can send sensing data to the SAF according to the reporting period. As another example, if the event triggering parameters include a precipitation threshold, the gNB can send sensing data to the SAF when the sensed precipitation reaches the precipitation threshold.

[0166] In one embodiment, the sensing data sent by the gNB can be raw data.

[0167] It should be noted that if the gNB has sufficient computing power, after the gNB obtains raw data through wireless sensing, the gNB can process the raw data to obtain the sensing results; and then send the sensing results to the SAF.

[0168] It is understood that the gNB can report sensing data to the SAF in multiple ways. In the first way, the gNB can send the sensing data to the SAF based on the SAF's IP address. In the second way, the gNB can send the sensing data to the SAF through the AMF. It should be noted that the gNB can also send sensing data to the SAF in other ways, and this disclosure does not specifically limit these methods.

[0169] In S309, SAF sends the sensing results to the station.

[0170] In S308, after receiving sensing data from gNB, SAF determines the sensing results of the precipitation monitoring service.

[0171] In one embodiment, the SAF receives sensing data from the gNB. The SAF can then process the sensing data to obtain sensing results.

[0172] In one embodiment, when the gNB sends sensing results to the SAF, the SAF can use the received sensing results as sensing results to be sent. In another embodiment, when the gNB sends sensing data to the SAF, the SAF can send the sensing data to the station.

[0173] Understandably, the sensing results can be numerical precipitation data, such as precipitation over the past hour or over the past 24 hours. Alternatively, the sensing results can be indications of whether a precipitation threshold has been reached. For example, the sensing results could indicate that precipitation has reached a threshold, such as 200 mm / day. After determining the sensing results for the precipitation monitoring service, SAF can send the determined sensing results to the stations.

[0174] In S310, the station sends a sensing termination request to the gNB via SAF.

[0175] After receiving the sensing results reported by SAF, the station can send a sensing stop request to gNG through SAF to terminate the provision of precipitation monitoring services.

[0176] In S311, gNB sends a termination response to the site via SAF.

[0177] Upon receiving a sensing termination request, the gNB can terminate wireless sensing and send a termination response (stop acknowledgement) to the site via SAF.

[0178] It should be noted that S310 and S311 are optional. In one embodiment, if the sensing request received by the gNB in ​​S304 carries sensing time information, and the sensing time information includes an end time or duration, the gNB may automatically terminate wireless sensing after the end time indicated by the sensing time information or after the duration has elapsed.

[0179] At this point, Figure 3 The workflow of the precipitation monitoring method based on sensing services, as shown, is now complete.

[0180] In this embodiment of the disclosure, event triggering parameters required to implement precipitation monitoring services are sent to the access network function, and the access network function performs precipitation monitoring based on the received event triggering parameters and feeds back the sensing data. In this way, this embodiment of the disclosure can provide precipitation monitoring sensing services based on mobile networks, thereby achieving large-scale, low-cost precipitation monitoring.

[0181] Based on the same inventive concept, this disclosure also provides a precipitation monitoring method based on sensing services, which can be applied to network functions such as SAF. Figure 4 This is a flowchart illustrating a precipitation monitoring method based on sensing services, as described in an embodiment of this disclosure. Figure 4 As shown, the method includes: S401 to S403.

[0182] In S401, the first message sent by the sensing requesting device is received.

[0183] The first message contains event triggering parameters for the precipitation monitoring service. These parameters are used to indicate the event that triggers the reporting of the sensing data from the precipitation monitoring service.

[0184] In S402, based on the first message, the second message is sent.

[0185] The second message contains event triggering parameters.

[0186] In S403, sensing data reported by the access network function is received.

[0187] In some possible implementations, the event triggering parameters may include at least one of the following: reporting cycle; precipitation threshold.

[0190] In some possible implementations, the operation S402 of sending the second message according to the first message may include: sending the second message through the core network function to the access network function.

[0194] In S501, the second message is received.

[0195] The second message contains event triggering parameters for the precipitation monitoring service. These parameters are used to indicate the event that triggers the reporting of the sensing data from the precipitation monitoring service.

[0196] In S502, precipitation monitoring services are processed based on the second message.

[0197] In S503, when a reported event occurs, sensing data is sent to the network function.

[0198] In some possible implementations, the event triggering parameters may include at least one of the following: reporting cycle; precipitation threshold.

[0199] In some possible implementations, the event triggering parameter may include a reporting period, whereby a reporting event occurs when the reporting period is reached.

[0200] In some possible implementations, the event triggering parameter may include a precipitation threshold, and the reported event is when the precipitation sensed by the access network function reaches the precipitation threshold.

[0201] In some possible implementations, receiving the second message may include receiving the second message sent by the network function via the core network function.

[0202] In some possible implementations, prior to the operation S501 of receiving the second message, the above method may further include: sending sensing capability information, which indicates that the access network function supports precipitation monitoring services.

[0203] In some possible implementations, the operation of sending sensing capability information may include sending a registration request message that carries the sensing capability information.

[0204] Based on the same inventive concept, this disclosure also provides a precipitation monitoring method based on sensing services, which can be applied to sensing requester devices, such as stations. Figure 6This is a flowchart illustrating another precipitation monitoring method based on sensing services, as described in this disclosure. Figure 6 As shown, the method includes: S601 and S602.

[0205] In S601, the first message is sent to the network function.

[0206] The first message contains event triggering parameters for the precipitation monitoring service. These parameters are used to indicate the event that triggers the reporting of the sensing data from the precipitation monitoring service.

[0207] In S602, sensing data and / or sensing results from the precipitation monitoring service of the network function are received.

[0208] In some possible implementations, the event triggering parameters may include at least one of the following: reporting cycle; precipitation threshold.

[0209] In some possible implementations, the event triggering parameter may include a reporting period, whereby a reporting event occurs when the reporting period is reached.

[0210] In some possible implementations, the event triggering parameter may include a precipitation threshold, and the reported event is when the precipitation sensed by the access network function reaches the precipitation threshold.

[0211] It should be noted that, in this implementation, the execution flow of the network function side, access network function side, and sensing requester device side can be found in the above-mentioned... Figure 3 The detailed description of the precipitation monitoring process based on sensing services in the embodiment is omitted here for the sake of brevity.

[0239] Based on the same inventive concept, this disclosure provides an electronic device that can be a network function, access network function, or sensing requester device as described in one or more of the above embodiments. Figure 9 This is a schematic diagram of the structure of an electronic device according to an embodiment of this disclosure. Figure 9 As shown, the electronic device 900 uses general-purpose computer hardware, including a processor 901, a memory 902, a bus 903, an input device 904, and an output device 905.
