[0094] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0095] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure. The singular forms "a," "an," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include 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 associated listed items.

[0096] It should be understood that although the terms "first", "second", "third" and the like may be used to describe various elements in the present 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 the present disclosure, the "first element" may also be referred to as the "second element", and similarly, the "second element" may also be referred to as the "first element". Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0097] Furthermore, in the description of the embodiments of the present disclosure, "and / or" is merely a description of the association relationship between associated 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. Furthermore, in the description of the embodiments of the present disclosure, "plurality" can refer to two or more than two.

[0098] The development of AI technology has significantly boosted the intelligentization of numerous industries, with perception technology becoming a crucial foundation. Radar-based perception technology is widely used in smart transportation, autonomous driving, and people counting. Currently, radar-based perception technology primarily relies on dedicated radar equipment. However, dedicated radar equipment suffers from high costs and inflexible deployment, limiting its use to specific scenarios.

[0099] 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 fifth-generation (5G) mobile communications to provide sensing services based on communication systems. In particular, due to the large number and widespread distribution of access network functional entities and terminal devices, they have become the primary providers of sensing services. In some scenarios, access network equipment can be used to provide sensing services, such as detecting animals or objects on highways and sensing weather conditions.

[0100] As the electronic devices most frequently used and contacted by users, terminal devices such as mobile phones can subscribe to or obtain such awareness services. However, in related technologies, terminal devices cannot obtain wireless awareness services provided by access network devices.

[0101] Therefore, how to enable access network equipment to support the perception services subscribed by terminal equipment is an urgent problem to be solved.

[0102] Figure 1 is a schematic diagram of a scenario for providing wireless perception services in an embodiment of the present disclosure. As shown in Figure 1, a terminal device 102 served by an access network function entity 101A subscribes to a perception service from a perception server, and the perception server requests the access network function entity 101B to provide the perception service. The access network function entity 101B can perform wireless perception of the surrounding environment (i.e., process the perception service) to obtain perception data for the perception service. Subsequently, the access network function entity 101B can send the perception data to the perception server via the core network 103 to realize perception data collection. After completing the perception data collection, the perception server can generate perception service data based on the perception data and send the perception service data to the terminal device 102.

[0103] It should be noted that in the scenario shown in Figure 1, the access network function entity 101B providing the awareness service is different from the access network function entity 101A serving the terminal device 102. In this case, the access network function entity 101B has the wireless awareness function, while the access network function entity 101A does not need to have the wireless awareness function.

[0104] In addition, only one access network function entity 101B is shown in Figure 1. It is understandable that in actual applications, there may be multiple access network function entities 101B providing awareness services.

[0105] It is understandable that, in another scenario (not shown), the access network functional entity serving the terminal device is the access network functional entity providing the awareness service. In this case, the access network functional entity has a wireless awareness function.

[0106] In order to provide wireless perception services, an embodiment of the present disclosure provides a communication system. Figure 2 is a structural diagram of a communication system providing wireless perception services in an embodiment of the present disclosure. As shown in Figure 2, the above-mentioned communication system 200 may include access network equipment and core network equipment, which may be access network equipment and core network equipment of any generation; illustratively, taking the 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 the present disclosure, the 5G network system is used as an example for explanation; of course, those skilled in the art will understand that the technical solution of the present disclosure can be used in any generation of communication systems, 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 via the Uu interface.

[0107] The 5G core network 203 may include: an access and mobility management function (AMF) entity 2031, a user plane function (UPF) entity 2032, a session management function (SMF) entity 2033, a policy control function (PCF) entity 2034, a unified data management (UDM) entity 2035, etc.

[0108] The sensing function (SF) entity may be implemented by a sensing server 204, which is located outside the 5G core network 203 and connected to a UPF entity 2032 in the 5G core network 203. It is understood that in some cases, the SF entity may also be located inside the 5G core network 203. In this case, the SF entity may be a network function in the 5G core network 203.

[0109] In the embodiment of the present disclosure, the above-mentioned communication system may further include other network function entities, which is not specifically limited in the embodiment of the present disclosure.

[0110] It should be noted that the above-mentioned network functions can also be described as network function entities, network elements, network function components, network function modules, network devices, etc.

[0111] In addition, in order to make the description more concise, the "entity" in each functional entity will be removed in the subsequent description. For example, the PCF entity is referred to as PCF, and the AMF entity is referred to as AMF. Other entities are similar and will not be listed one by one.

[0112] In the above communication system, the terminal device 202 can access the 5G core network through the 3rd Generation Partnership Project (3GPP) technology. Specifically, the terminal device 202 can access the 5G core network through a 3GPP access network device.

[0113] In the above communication system, UDM 2035 has the function of unified data management, mainly responsible for managing contract data, user access authorization and other functions.

[0114] PCF 2034 has a policy control function and is mainly responsible for policy decisions related to charging policies for sessions and business flows, 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.

[0115] SMF 2033 has a session management function, mainly performing session management, execution of control policies issued by PCF 2034, selection of UPF 2032, and allocation of Internet Protocol (IP) addresses of terminal devices 202.

[0116] The AMF 2031 has access and mobility management functions, mainly performing mobility management, access authentication / authorization, etc. In addition, it is also responsible for transmitting user policies between the terminal device 202 and the PCF 2034.

[0117] The UPF 2032 is a user plane functional entity that serves as an interface with the data network and implements user plane (UP) data forwarding, session / flow-level billing statistics, bandwidth limitation, and other functions.

[0118] The functions of each interface are described as follows:

[0124] N2: Interface between AMF 2031 and NG-RAN 201, used to transmit radio bearer control information from the core network side to NG-RAN 201.

[0125] N1: The interface between AMF 2031 and terminal device 202, which is independent of access and is used to transmit QoS control rules, etc. to terminal device 202.

[0126] N8: Interface between AMF 2031 and UDM 2035, used by AMF 2031 to obtain access and mobility management-related subscription data and authentication data from UDM 2035, and for AMF 2031 to register UE current mobility management-related information with UDM 2035.

[0127] N10: The interface between SMF 2033 and UDM 2035 is used for SMF 2033 to obtain session management related subscription data from UDM 2035, and for SMF 2033 to register UE current session related information with UDM 2035.

[0128] The terminal device 202 may be a terminal device with wireless communication capabilities, and may also be referred to as user equipment (UE). The terminal device may be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it may also be deployed on water (such as ships, etc.); it may also be deployed in the air (such as airplanes, balloons, and satellites, etc.). The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The terminal device may also be a handheld device with wireless communication capabilities, a vehicle-mounted device, a wearable device, a computing device, or other processing device connected to a wireless modem. Optionally, the terminal device may be called different names in different networks, such as: terminal device, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), terminal device in 5G network or future evolution network, etc.

[0129] The NG-RAN 201 may be a device on the access network side for supporting the terminal device 202 to access the wireless communication system. For example, it may be a next generation NodeB (gNB), a transmission reception point (TRP), a relay node, an access point (AP), etc. in a 5G access technology communication system.

[0130] It should be noted that in the communication system shown in Figure 2, the functions and interfaces of each device are merely exemplary, and not all functions of each device are required when used in the embodiments of the present disclosure. All or part of the core network devices may be physical entities or virtualized devices, without limitation here. Of course, the communication system in the embodiments of the present disclosure may also include other devices not shown in Figure 2, without limitation here.

[0131] To address the aforementioned issues, embodiments of the present disclosure provide a method for providing a wireless awareness service. This method can be applied to the aforementioned communication system. For example, the terminal device is a UE, the access network function entity (or access network device) may include a first access network function entity (e.g., a first gNB) and a second access network function entity (e.g., a second gNB), the network function entity may be an SF, the first core network device may be a first AMF, and the second core network device may be a second AMF.

[0132] Figure 3 is a flow chart of a first embodiment of a method for providing wireless awareness services according to an embodiment of the present disclosure. As shown in Figure 3 , the method for providing wireless awareness services according to an embodiment of the present disclosure may include: S301 to S313.

[0133] S301, the UE sends an awareness service request message to the first AMF.

[0134] Among them, the perception service request message (also called the third request message) is used to request the provision of perception service.

[0135] In actual applications, the UE can send an awareness service request message based on user input or actual needs to request the provision of an awareness service. In one embodiment, the UE can subscribe to an awareness service for a location. For example, the location can be a location point or a location area. It is understood that the location can be a geographic location, an administrative area, or other types of locations.

[0136] In one embodiment, the awareness service request message sent by the UE to the first AMF may carry parameter information of the awareness service. The parameter information of the awareness service may be information required to implement the awareness service. For example, the parameter information may include at least one of the following: awareness service identification information, awareness service type information, awareness location information, and awareness time information.

[0137] The sensory service identification information is used to identify the sensory service. In other words, different sensory services have different sensory service identification information, thereby enabling differentiation between different sensory services. Each sensory service typically has unique sensory service identification information. For example, the sensory service identification information can be represented in the form of a string or a numeric value.

[0138] The sensing service type information is used to indicate the type of sensing service. For example, depending on the urgency of the sensing service, the sensing service type may include: emergency sensing service, non-emergency sensing service. For another example, depending on the object of the sensing service, the sensing service type may include: posture sensing, environmental sensing, pedestrian flow sensing, etc.

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

[0140] The perception time information is used to indicate the time taken to process the perception service. The processing time may include at least one of the following: start time, end time, and duration. For example, the processing time may include the start time and end time. For another example, the processing time may include both the start time and duration. For another example, the processing time may include only the end time. For another example, the processing time may include only the duration. For another example, if the perception service requires multiple perceptions, the processing time may include at least one of the following: the number of perceptions, the perception frequency, the perception interval, the start time and end time of each perception, and the start time and duration of each perception.

[0141] It should be noted that the parameter information of the perception service may also include other information (for example, perception range information, perception accuracy information), and each of the above-mentioned perception service identification information, perception service type information, perception location information, and perception time information may also adopt any other suitable form, and the embodiments of this disclosure do not make specific limitations on this.

[0142] It is understood that the UE can send the Awareness Service Request message to the first AMF in two ways. In the first way, the UE can send the Awareness Service Request message to the first gNB via the Uu interface. After receiving the Awareness Service Request message from the UE, the first gNB forwards the Awareness Service Request message to the first AMF via the N2 interface. In the second way, the UE can send the Awareness Service Request message to the first AMF via the N1 interface. In this case, the gNB transparently transmits the Awareness Service Request message from the UE to the first AMF. In one embodiment, the UE can send the Awareness Service Request message to the first AMF through a partial process of the Service Request Procedure. Specifically, the UE can send the Service Request message to the first gNB; then, the gNB can send the Service Request message (N2 message) to the first AMF. Here, the Service Request message can be used to implement or carry the Awareness Service Request message. In one embodiment, the UE can send the Awareness Service Request message to the first AMF through a partial process of the PDU Session Establishment Procedure. Specifically, the UE can send a PDU Session Establishment Request message to the first AMF. Here, the service request message can be used to implement or carry the awareness service request message. It should be noted that the UE can also send the awareness service request message to the first AMF through other methods or processes, and this embodiment of the present disclosure does not specifically limit this.

[0143] S302: The first AMF sends an awareness service request message to the SF.

[0144] Among them, the perception service request message (also referred to as the first request message) is used to request the provision of perception service.

[0145] It is understandable that after the first AMF receives the awareness service request message from the UE in S301, it obtains the parameter information of the awareness service from the awareness service request message. Subsequently, the first AMF sends the awareness service request message to the SF, and the awareness service request message carries the obtained parameter information.

[0146] In one embodiment, the awareness service request message sent by the first AMF to the SF may also carry other information. For example, the awareness service request message may also carry identification information of the first AMF.

[0147] It should be noted that before the first AMF sends a sensing service request message to an SF, it may need to determine the SF to which the sensing service request message is to be sent. In other words, the first AMF selects an SF. Specifically, the first AMF may determine the SF based on the sensing service request message received from the UE, or may determine the SF based on pre-configuration. In one embodiment, the first AMF may determine the SF based on the parameter information of the sensing service. For example, the first AMF may determine the SF based on at least one of the sensing service identification information, sensing service type information, sensing location information, and sensing time information in the parameter information. For example, the first AMF may determine the SF that best matches the sensing service type based on the sensing service type information. For another example, the first AMF may determine the SF closest to the location where the sensing service is being provided based on the sensing location information. For another example, the first AMF may determine the SF that is operating normally or has the lowest load during the sensing service period based on the sensing time information. In one embodiment, the first AMF may determine the SF based on pre-configuration. For example, the first AMF may determine the SF with the lowest communication delay with itself. For another example, the first AMF may determine the SF that is closest to itself.

[0148] In practical applications, the SF can be deployed within or outside the core network. In the former case, the SF can be a core network functional entity. In the latter case, the SF can communicate with the core network functional entity via wired or wireless communication. In another embodiment, the control plane of the SF can be deployed within the core network, while the user plane can be deployed outside the core network. Of course, the embodiments of this disclosure do not specifically limit the deployment method of the SF.

[0149] S303, SF selects the second AMF.

[0150] After receiving the perception service request message in S302, the SF determines the second AMF according to the parameter information carried in the perception service request message.

[0151] In one embodiment, the second AMF shall meet the following conditions: the coverage of at least one gNB connected to the second AMF covers the location where the sensing service is provided, and / or the distance between at least one gNB connected to the second AMF and the location is closest, or less than or equal to a preset distance. In this case, the SF may determine the second AMF that meets the above conditions based on the sensing location information in the parameter information. It should be noted that in the embodiments of this disclosure, "coverage" includes both full coverage and partial coverage (i.e., partial overlap).

[0152] In one embodiment, the SF may locally store and maintain information related to gNBs supporting radio awareness services, such as gNB identification information, gNB awareness capability information, and gNB location information. In this case, the SF can determine the second gNB based on this information and the obtained parameter information. The SF can then determine the second AMF based on the information related to the second gNB. In one embodiment, the SF can obtain information related to the second gNB from other functional entities in the core network based on the parameter information and thereby determine the second AMF. In one embodiment, the SF can obtain information related to the second AMF from other functional entities in the core network based on the parameter information and thereby directly determine the second AMF.

[0153] S304, SF sends an awareness service request message to the second AMF.

[0154] The awareness service request message (also referred to as a second request message) is used to request provision of an awareness service, and the awareness service request message carries parameter information.

[0155] In one embodiment, the awareness service request message sent by the SF to the second AMF may also carry the identification information of the second AMF. In one embodiment, the awareness service request message may also carry the identification information of the second gNB.

[0156] S305: The second AMF sends a perception request message to the second gNB.

[0157] Among them, the perception request message (also called the fourth request message) is used to request the provision of perception service.

[0158] In one embodiment, the awareness request message may carry parameter information. For example, the awareness request message may carry awareness service identification information and / or awareness time information. In one embodiment, the awareness request message may also carry identification information of the second gNB.

[0159] It should be noted that before the second AMF sends the perception request message to the second gNB, the second AMF may need to determine the second gNB. In one embodiment, the second gNB must meet the following conditions: the second gNB's coverage covers the location where the perception service is provided, and / or at least one gNB connected to the second AMF is closest to the location, or is less than or equal to a preset distance. In this case, the second AMF can determine the second gNB that meets the above conditions based on the perception location information in the parameter information. In one embodiment, the second gNB may be all gNBs connected to the second AMF.

[0160] Of course, when the perception service request message received from the SF carries the identification information of the second gNB, the second AMF can directly determine the second gNB based on the identification information.

[0161] Figure 3 shows a first gNB and a second gNB, as well as a first AMF and a second AMF. It should be understood that the first gNB and the second gNB can be different gNBs or the same gNB, and the first AMF and the second AMF can be different AMFs or the same AMF. For example, in some cases (e.g., when the UE is located very close to the location where the awareness service is provided), the first AMF and the second AMF can be the same AMF, and both the first gNB and the second gNB can be connected to the same AMF. Furthermore, the first AMF and the second AMF can be the same AMF, and the first gNB and the second gNB can be the same gNB. Furthermore, in some cases, the second gNB may include multiple gNBs. In this case, the first gNB may be different from each of the second gNBs, or it may be one of the second gNBs. In some cases, the second AMF may include multiple AMFs. In this case, the first AMF may be different from each of the second AMFs, or it may be one of the second AMFs.

[0162] S306: The second gNB sends a perception response message to the second AMF.

[0163] The perception response message (also referred to as the fourth response message) is used to indicate that the perception service is provided. Alternatively, the perception response message may also be used to indicate that the perception service is not provided.

[0164] It is understood that after receiving the awareness request message in S305, the second gNB can obtain parameter information of the awareness service from the awareness request message. Thereafter, the second gNB can configure the awareness service based on the parameter information.

[0165] In one embodiment, if the SF determines in S303 that the second gNB's radio sensing capabilities support the sensing service, the second gNB may configure the sensing service after receiving the sensing request message. In one embodiment, if the SF does not determine in S303 that the second gNB's radio sensing capabilities support the sensing service, before the second gNB configures the sensing service, the second gNB may determine whether to provide the sensing service based on parameter information. In one example, the second gNB may determine, based on the sensing service type information, whether the type of sensing service supported by the second gNB matches the sensing service type information. In another example, the second gNB may determine, based on the sensing time information, whether the second gNB can provide the sensing service within the time period indicated by the sensing time information.

[0166] Therefore, if the second gNB determines that it can provide the awareness service, the second gNB may send a sensing response message to the second AMF to indicate that the awareness service is provided. For example, the sensing response message may be a sensing service accept message. If the second gNB determines that it cannot provide the awareness service, the second gNB may send a sensing response message to the second AMF to indicate that the awareness service is not provided. For example, the sensing response message may be a sensing service refuse message.

[0167] S307: The second AMF sends a perception service response message to the SF.

[0168] Among them, after receiving the perception response message from the second gNB in ​​S306, the second AMF can send a perception service response message (also referred to as a second response message) to the SF.

[0169] It is understandable that the awareness service response message may be used to indicate that the awareness service is provided, or alternatively, the awareness service response message may be used to indicate that the awareness service is not provided.

[0170] S308, SF sends a perception service response message to the first AMF.

[0171] Among them, after receiving the perception service response message from the second AMF in S307, the SF can send a perception service response message (also referred to as a first response message) to the first AMF.

[0172] It is understandable that the awareness service response message may be used to indicate that the awareness service is provided, or alternatively, the awareness service response message may be used to indicate that the awareness service is not provided.

[0173] S309: The first AMF sends an awareness service response message to the UE.

[0174] Among them, after receiving the perception service response message from the SF in S308, the first AMF can send a perception service response message (also referred to as a third response message) to the UE.

[0175] It is understandable that the awareness service response message may be used to indicate that the awareness service is provided, or alternatively, the awareness service response message may be used to indicate that the awareness service is not provided.

[0176] After the UE receives the Awareness Service Response message from the first AMF, it can determine whether it has successfully subscribed to the Awareness Service. If the Awareness Service Response message indicates that the Awareness Service is provided, the UE determines that it has successfully subscribed to the Awareness Service. Thereafter, the UE may further wait to receive subsequent Awareness Service data.

[0177] S310: The second gNB sends sensing data to the second AMF.

[0178] In S306, the second gNB determines that it supports the perception service. The second gNB may configure the perception service based on the parameter information and process the perception service. It should be noted that after the second gNB configures the perception service in S306, the second gNB may process the perception service.

[0179] In one embodiment, the second gNB may process the sensing service based on the sensing time information in the parameter information. In one embodiment, the second gNB may process the sensing service based on the sensing range information in the parameter information. In one embodiment, the second gNB may process the sensing service based on the sensing accuracy information in the parameter information.

[0180] After processing the sensing service, the second gNB obtains sensing data for the sensing service. It is understood that the sensing data obtained may be raw data or processed data obtained by processing the raw data. For example, the processed data may be a sensing result obtained by processing the data.

[0181] In one example, when sensing pedestrian flow, the raw data may be raw wireless signals from humans or animals received by the second gNB; the sensing results may be pedestrian flow statistics or heat map data obtained by processing the raw wireless signals. In another example, when sensing posture, the raw data may be raw wireless signals from humans or animals received by the second gNB; the sensing results may be posture data obtained by processing the raw wireless signals. In yet another example, when sensing weather, the raw data may be raw wireless signals from the surrounding environment received by the second gNB; the sensing results may be weather data obtained by processing the raw wireless signals.

[0182] After the second gNB obtains the perception data, the second gNB may send the perception data to the second AMF through the N2 interface.

[0183] S311: The second AMF sends perception data to the SF.

[0184] After receiving the perception data from the second gNB in ​​S310, the second AMF may send the perception data to the SF.

[0185] S312, SF sends perception service data to the first AMF.

[0186] In S311, the SF receives the sensing data of the sensing service. As mentioned above, the sensing data received by the SF may be original data, processed data, or sensing results.

[0187] In one embodiment, the perception data may be raw data or processed data. In this case, the SF may not perform data processing on the raw data or processed data, and the perception service data sent by the SF may be the raw data or processed data. Alternatively, the SF may perform data processing on the raw data or processed data to obtain a perception result, and the perception service data sent by the SF may be the perception result. In one embodiment, the perception data may be the perception result. In this case, the perception service data sent by the SF may be the perception result.

[0188] S313: The first AMF sends perception service data to the UE.

[0189] After receiving the perception service data in S312, the first AMF sends the perception service data to the UE. In one embodiment, the first AMF may send the perception service data to the UE via the first gNB.

[0190] At this point, the process of the method for providing wireless awareness services shown in FIG3 is completed.

[0191] In some possible implementations, embodiments of the present disclosure also provide a method for providing wireless awareness services. In this method, the SF triggers the establishment of a user plane connection. Figure 4 is a schematic flow diagram of a second embodiment of a method for providing wireless awareness services according to embodiments of the present disclosure. As shown in Figure 4, the method for providing wireless awareness services according to embodiments of the present disclosure may include steps S401 to S411.

[0192] S401, the UE sends an awareness service request message to the first AMF.

[0193] S402: The first AMF sends an awareness service request message to the SF.

[0194] S403, SF selects the second AMF.

[0195] S404, SF sends an awareness service request message to the second AMF.

[0196] S405: The second AMF sends a perception request message to the second gNB.

[0197] S406: The second gNB sends a perception response message to the second AMF.

[0198] S407: The second AMF sends a perception service response message to the SF.

[0199] It should be noted that the specific implementation process of the above S401 to S407 can refer to the description of the execution process of S301 to S307 in the embodiment of Figure 3, and will not be repeated here in the embodiment of the present disclosure.

[0200] S408: The SF establishes a user plane connection with the UE.

[0201] In S407, after the SF receives the awareness service response message from the second AMF, the SF may trigger a process for establishing a user plane connection to establish a user plane connection between the SF and the UE. In one example, the user plane connection between the SF and the UE may be based on a PDU session connection, and the process for establishing the user plane connection may be a PDU session establishment process. It should be noted that the user plane connection may also be established based on other processes, which is not specifically limited in the present embodiment.

[0202] It is understood that after receiving the establishment request from the SF, the UE may determine by default that the subscription to the awareness service is successful. Alternatively, after the user plane connection between the SF and the UE is successfully established, the SF may send an awareness service response message to the UE through the established user plane connection to indicate whether the awareness service is provided or not.

[0203] S409: The second gNB sends the sensing data to the second AMF.

[0204] S410: The second AMF sends perception data to the SF.

[0205] It should be noted that S409 and S410 in the method for providing wireless awareness services shown in Figure 4 are the same as S310 and S311 in the method for providing wireless awareness services shown in Figure 3. For the specific details of S409 and S410, refer to the description of S310 and S311 above, and will not be repeated here in this embodiment of the present disclosure.

[0206] S411, SF sends perception service data to UE.

[0207] After establishing the user plane connection in S408, the SF may send the perception service data to the UE through the established user plane connection.

[0208] As mentioned above, the perception data received by SF can be raw data, processed data, or perception results.

[0209] In one embodiment, the perception data may be raw data or processed data. In this case, the SF may not perform data processing on the raw data or processed data, and the perception service data sent by the SF may be the raw data or processed data. Alternatively, the SF may perform data processing on the raw data or processed data to obtain a perception result, and the perception service data sent by the SF may be the perception result. In one embodiment, the perception data may be the perception result. In this case, the perception service data sent by the SF may be the perception result.

[0210] For example, the user plane connection between the SF and the UE may be based on a PDU session connection. In this case, the SF may send the perception service data to the UPF; thereafter, the UPF may send the perception service data to the UE via the PDU session connection.

[0211] At this point, the process of the method for providing wireless awareness services shown in FIG4 is completed.

[0212] In some possible implementations, embodiments of the present disclosure also provide a method for providing wireless awareness services. In this method, the UE triggers the establishment of a user plane connection. Figure 5 is a schematic flow diagram of a third embodiment of a method for providing wireless awareness services according to embodiments of the present disclosure. As shown in Figure 5, the method for providing wireless awareness services according to embodiments of the present disclosure may include steps S501 to S513.

[0221] S509: The first AMF sends an awareness service response message to the UE.

[0222] It should be noted that S501 to S509 in the method for providing wireless awareness services shown in Figure 5 are the same as S301 to S309 in the method for providing wireless awareness services shown in Figure 3. For the specific details of S501 to S509, refer to the description of S301 to S309 above, and will not be repeated in this embodiment of the present disclosure.

[0223] S510: The UE establishes a user plane connection with the SF.

[0224] In S509, after the UE receives the awareness service response message from the first AMF, the UE may trigger a process for establishing a user plane connection to establish a user plane connection between the SF and the UE. In one example, the user plane connection between the SF and the UE may be based on a PDU session connection, and the process for establishing the user plane connection may be a PDU session establishment process. It should be noted that the user plane connection may also be established based on other processes, which is not specifically limited in the embodiments of the present disclosure.

[0225] S511: The second gNB sends sensing data to the second AMF.

[0227] It should be noted that S511 and S512 in the method for providing wireless awareness services shown in Figure 5 are the same as S310 and S311 in the method for providing wireless awareness services shown in Figure 3.

[0228] S513, SF sends perception service data to UE.

[0229] After establishing the user plane connection in S513, the SF may send the perception service data to the UE through the established user plane connection.

[0230] As mentioned above, the perception data received by SF can be raw data, processed data, or perception results.

[0231] In one embodiment, the perception data may be raw data or processed data. In this case, the SF may not perform data processing on the raw data or processed data, and the perception service data sent by the SF may be the raw data or processed data. Alternatively, the SF may perform data processing on the raw data or processed data to obtain a perception result, and the perception service data sent by the SF may be the perception result. In one embodiment, the perception data may be the perception result. In this case, the perception service data sent by the SF may be the perception result.

[0232] For example, the user plane connection between the SF and the UE may be based on a PDU session connection. In this case, the SF may send the perception service data to the UPF; thereafter, the UPF may send the perception service data to the UE via the PDU session connection.

[0233] At this point, the process of the method for providing wireless awareness services shown in FIG5 is completed.
