[0326] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0327] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0328] In the embodiments of the present disclosure, the terms "first," "second," and the like are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present disclosure can be implemented in an order other than that illustrated or described herein. Furthermore, the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more.

[0329] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0330] In order to facilitate a clearer understanding of the technical solutions of the various embodiments of the present disclosure, some technical contents related to the various embodiments of the present disclosure are first introduced.

[0331] 1. 5G synaesthesia fusion.

[0332] Communication-perception fusion achieves unified design of communication and perception functions through joint signal design and / or hardware sharing. The perception in communication-perception fusion can be understood as a wireless perception technology based on communication systems. This technology transmits wireless signals to target areas or objects and analyzes the received wireless signals to obtain corresponding perception measurement information. Therefore, wireless communication networks naturally possess wireless perception capabilities. Base stations and terminals will have both communication and perception capabilities, providing perception services for perception applications, including intelligent transportation, drone monitoring, national railway perimeter security inspections, smart homes, public safety, health monitoring, and environmental monitoring.

[0333] 2. 5G synaesthesia-integrated network architecture.

[0334] Considering the degree of coupling between perception functions and existing functional modules in 5GC, synaesthesia network architectures can be roughly divided into two types: tightly coupled and loosely coupled. Related technologies propose adding a new functional network element (SF) for perception in 5GC, primarily responsible for perception control and perception measurement data calculation. SF can include two logical perception functions, SF-C and SF-U. SF-C is the perception control plane function, and control signaling between SF-C and the terminal (or user equipment, UE) and the radio access network (Radio Access Network, RAN) is transmitted via the Access and Mobility Management Function (AMF). SF-U is the perception user plane function, and the UE and RAN transmit perception measurement data to SF-U. SF-C and SF-U may also be logically inseparable. The SF logical function can be integrated with functions such as the Location Management Function (LMF), or the LMF can be directly enhanced to implement this function.

[0335] Figure 1 is a schematic diagram of a tightly coupled synaesthesia network architecture provided by related art, and Figure 2 is a schematic diagram of a loosely coupled synaesthesia network architecture provided by related art. Part (a) of Figure 1 illustrates a tightly coupled synaesthesia network architecture with undivided CUs (i.e., no distinction between SF-C and SF-U), while part (b) of Figure 1 illustrates a tightly coupled synaesthesia network architecture with separated CUs (i.e., separate SF-C and SF-U).

[0336] The main network functions (NFs) and interfaces involved in Figures 1 and 2 are described as follows:

[0337] AMF: Access and mobility management function, responsible for registration, connection management, etc.

[0338] UPF: User Plane Function, is an external Protocol Data Unit (PDU) session node interconnected with the Data Network (DN), responsible for message routing and forwarding.

[0339] SMF: Session Management Function. Responsible for session establishment and deletion, user plane selection and control, and UE Internet Protocol (IP) address allocation.

[0340] AF: Application Function, which interacts with the 3GPP core network to provide services. Based on operator deployment, trusted AFs can interact directly with relevant NFs, while untrusted AFs cannot interact directly with NFs and must use an open framework through the Network Exposure Function (NEF).

[0341] NWDAF: Network Data Analytics Function, which can provide network analysis services based on the request data of network services.

[0342] PCF: Policy Control Function. Supports a unified policy framework to manage network behavior and provide policy rules for control plane NFs to execute.

[0343] NRF: Network Repository Function. Supports service discovery.

[0344] UDM: Unified Data Management. Stores UE information, such as subscription information and information about established PDU sessions.

[0345] NEF: Network Exposure Function. Provides functions related to securely exposing the services and capabilities provided by the 3GPP network to external networks.

[0346] NSSF: Network Slice Selection Function. Determines the network slice instances that the UE is allowed to access based on the UE's slice selection auxiliary information, subscription information, etc.

[0347] AUSF: Authentication Server Function. Implements 3GPP and non-3GPP access authentication.

[0348] SF-C: Perception control plane function, control signaling between UE and RAN is transmitted through AMF.

[0349] SF-U: Perception user plane function. UE and RAN transmit perception measurement data to SF-U.

[0350] NS1: NS1 is a new interface between SF and AMF, which can transmit perception control signaling and perception measurement data.

[0351] NS2: NS2 is a new interface between SF and NEF. This interface can transmit signaling messages between the perception network element and the service-side AF through NEF, and open the perception results to AF.

[0352] NS3: NS3 is a new interface between SF and UDM, through which authentication or authorization can be achieved, and UE perception subscription information, service AMF information or other information can be obtained.

[0353] NS4: NS4 is a new interface between SF and NWDAF. Through this interface, SF and NWDAF can jointly complete artificial intelligence (AI) processing related to perception services.

[0354] NS5: NS5 is a new interface between SF and PCF. Through this interface, SF can pass information such as the perception requirements, Quality of Service (QoS) requirements or perception results of the perception service to PCF. PCF decides and generates Policy Control and Charging (PCC) policies related to the perception service.

[0355] NS6: NS6 is a new interface between SF and LMF. Through this interface, SF can obtain location-related information, such as the sensing area, (R)AN information of the sensing target, and the location information of the sensed UE.

[0356] NS7: A new interface is added between SF (or SF-U) and UPF. Perception measurement data can be directly transmitted from the (R)AN to the perception network element via the user plane function, or indirectly forwarded to the perception network element via the UPF. If the (R)AN performs perception and forwards the data via the UPF, the UPF needs to be modified to support data transmission at the (R)AN granularity.

[0357] NS8: A new interface is added between SF-C and SF-U. Through this interface, perception processing strategies can be transmitted and perception results can be reported.

[0358] N1, N2, N3, N4, N5, N6, N7, N8, N10, N12, N15, N22, N33, and Uu are existing interfaces of traditional 5GC and are not described here.

[0359] 3. Perception method.

[0360] Figure 3 is a schematic diagram of the six basic sensing methods provided by related technologies. As shown in Figure 3, the six basic sensing methods include base station self-transmission and self-reception (Monostatic), base station A transmits and base station B receives (Bistatic), UE transmits and base station receives (Bistatic), UE self-transmission and self-reception (Monostatic), UE-A transmits and UE-B receives (Bistatic), and base station transmits and UE receives (Bistatic). In addition, in the actual sensing process, a combination of the above six sensing methods can be used for perception based on different sensing scenarios, sensing environments, and sensing service requirements.

[0361] 4. Perception process.

[0362] Figure 4 is an example diagram of the signaling interaction of the perception process provided by the relevant technology. Figure 4 illustrates the perception process when the perception mode is self-transmitting and self-receiving by the base station or when base station A transmits and B receives under the CU separation architecture. The perception process of other perception modes is similar and will not be described in detail. As shown in Figure 4, the main process includes:

[0363] Step 1: The SF selects a suitable RAN based on the target area information / target object location information and sends a perception control request to the RAN to control the RAN to perform perception detection. The request also carries the IP address and port number of the SF-U for receiving perception measurement data.

[0364] Step 2: RAN detects and obtains the perception measurement data.

[0365] Step 3: RAN reports the sensing measurement data to SF-U.

[0366] Step 4: SF-U reports to SF-C that it has received the sensing measurement data.

[0367] Related technologies have proposed architectures with both CU-integrated and CU-integrated sensing functions, as well as sensing processes tailored to different sensing methods. However, these approaches have not considered how to support distributed, on-demand deployment of sensing services, how to support multi-SF-U or SF collaboration to achieve low-latency information transmission, meet information confidentiality requirements, and rationally allocate transmission resources.

[0368] FIG5 is a flow chart of a method for deploying an awareness service according to an embodiment of the present disclosure. The method can be applied to a first SF. As shown in FIG5 , the method includes the following steps:

[0369] Step 500: Receive a first perception request sent by a control plane network element.

[0370] Step 501: Determine one or more second SFs based on the first perception request, and send perception data processing rules to the one or more second SFs.

[0371] Specifically, the first SF may be a CU-integrated SF or SF-C, and the second SF may be a CU-integrated SF or SF-U. The one or more second SFs may all be CU-integrated SFs, all SF-Us, or some may be CU-integrated SFs and some may be SF-Us, which is not limited in the present embodiment.

[0372] In the embodiment of the present disclosure, SF-U may include the following two types:

[0373] Type 1: Responsible for collecting and analyzing the perception measurement data generated by terminals or base stations, obtaining the final perception results, and opening the perception results to UEs or applications. That is, Type 1 SF-U can perform functions such as data collection, data perception, calculation and analysis.

[0374] Type 2: Responsible for collecting perception measurement data and reporting the perception measurement data to SF-C (SF-C analyzes the perception measurement data to obtain perception results and opens them to UE or applications, etc.). That is, the type 2 SF-U only performs data collection functions and does not perform data perception, calculation and analysis functions.

[0375] In the embodiment of the present disclosure, the SF-Us in the one or more second SFs (if CU-separated SF-Us exist) may all be type-1 SF-Us, or all be type-2 SF-Us, or some may be type-1 SF-Us and some may be type-2 SF-Us, and the embodiment of the present disclosure does not impose any restrictions.

[0376] In some embodiments, the SF may be an LMF. For example, the perception function may be integrated with the LMF, or the LMF may be directly enhanced to implement the function.

[0377] In the embodiments of the present disclosure, the control plane network element may be any control plane network element in the core network, and is not specifically limited here. In some embodiments, the control plane network element may include an AMF or a consumer network element of a perception service, wherein the consumer network element of the perception service may include an NWDAF, PCF, LMF, etc.

[0378] The control plane network element may select a first SF according to the perception requirement, and then send a first perception request to the first SF.

[0379] In some embodiments, the perception request may be initiated by AF, application server (AS), UE or NF, and the AF / AS / UE / NF sends the perception requirement to the control plane network element. The control plane network element selects the first SF according to the perception requirement, and then sends the first perception request to the first SF.

[0380] In some embodiments, the control plane network element (such as a consumer network element of the perception service) may select the first SF when it has a perception requirement, and then send a first perception request to the first SF.

[0381] In some embodiments, the first perception request includes one or more of the following: perception accuracy, perception resolution, frame rate, perception time, target area information, QoS requirements, and perceived target information.

[0382] In some embodiments, the perception time may include one or more of the following: perception duration (i.e., the length of time to perform perception), perception start time, perception cycle (i.e., how long it takes to perform perception), feedback cycle (i.e., how long it takes to feedback perception data), and feedback duration (i.e., how long it takes to feedback perception data).

[0383] In some embodiments, the target area information includes information indicating the target area to be sensed, for example, the information may indicate a specific geographical area, one or more tracking area identifiers (TAI), one or more cell identifiers (Cell ID), etc.

[0384] In some embodiments, the perceived target may be a vehicle, and the perceived target information may include the type of the perceived vehicle, the vehicle identification of the perceived vehicle, the location information of the perceived vehicle, etc. Of course, this is only an example, and the perceived target may also be any other perceived object, and this disclosure is not limited thereto.

[0385] In some embodiments, the first perception request may also include information of one or more second SFs, which may be the identifier, IP address, etc. of the SF.

[0386] After receiving the first perception request, the first SF may determine one or more second SFs based on the first perception request, and then send perception data processing rules to the one or more second SFs.

[0387] In some embodiments, the perception data processing rules include one or more of the following:

[0388] (1) Data processing method: The data processing method may include direct forwarding, generating intermediate data, or generating final perception results.

[0389] (2) Address information of the sink node. This address information may include, for example, an IP address, a port number, etc.

[0390] (3) Address information of the target receiving end. The target receiving end may be, for example, an AF, an AS, a UE, a NF, a consumer network element that perceives the service, etc. The address information may include, for example, an IP address, a port number, etc.

[0391] (4) Sink node indication: The sink node indication is information indicating whether the SF receiving the sensing data processing rule is a sink node.

[0392] (5) Data collection requirements: The data collection requirements may include, for example, the type of data being sensed, data accuracy, the time it takes to collect data, the time it takes to provide data, etc.

[0393] (6) Perception requirements: The perception requirements may include, for example, perception accuracy, perception resolution, perception precision, frame rate, perception time, target area information, QoS requirements, and perceived target information.

[0394] In some embodiments, the first perception request includes information of one or more second SFs. In this case, the first SF can directly determine the one or more second SFs based on the information of the one or more second SFs carried in the first perception request.

[0395] In some embodiments, determining one or more second SFs based on the first perception request may include: querying the NRF for information of the one or more second SFs based on the first perception request; or determining one or more second SFs based on the first perception request and local configuration information.

[0396] For example, the first SF can query the NRF through the network element discovery service for information about one or more second SFs that can match the demand for perception service in the first perception request; or, if the first SF is locally configured with information about the second SF, the first SF can query the local configuration information and select a suitable second SF based on the demand for perception service in the first perception request.

[0397] In some embodiments, querying the NRF for information of one or more second SFs includes:

[0398] Send a first network element discovery request message to the NRF, where the first network element discovery request message includes one or more of the following: data network access identifier (DNAI), single network slice selection assistance information (S-NSSAI), area information, and perception type (for example, type 1 or type 2 described above);

[0399] Receive a first network element discovery response message sent by the NRF, where the first network element discovery response message includes information of one or more second SFs, which may be an identifier, IP address, port number, etc. of the SF.

[0400] In the method for deploying perception services provided by the embodiments of the present disclosure, the first SF can determine one or more second SFs based on the first perception request sent by the control plane network element, and send perception data processing rules to the one or more second SFs. This allows the perception service to be uniformly managed by the core network, and enables flexible on-demand deployment of SF-U / SF that meets different capability requirements. It also supports collaboration among multiple SF-U / SFs, and can support application scenarios with low transmission latency and information confidentiality requirements, while achieving load balancing and reasonable resource allocation on the SF-U / SF.

[0401] In some embodiments, the method further comprises:

[0402] Send the first registration information to the NRF, where the first registration information includes one or more of the following: the service area of ​​the first SF and the perception capability of the first SF.

[0403] Specifically, the first SF may register its own information with the NRF, for example, information such as the service area of ​​the first SF, the sensing capability of the first SF (such as the supported sensing methods), etc., so that other network elements can discover the first SF through the NRF when needed.

[0404] In some embodiments, the first registration information further includes registration information of the second SF, and the registration information of the second SF includes one or more of the following: the service area of ​​the second SF, the perception capability of the second SF, the DNAI supported by the second SF, the S-NSSAI supported by the second SF, the type of data that can be collected by the second SF, the data collection delay supported by the second SF, and the data accuracy supported by the second SF.

[0405] Specifically, when the first SF is locally configured with information about the second SF, in addition to registering the information of the first SF itself, the first SF may also register the information of the second SF with the NRF. It should be noted that the second SF here may include one or more second SFs determined by the first SF based on the first perception request, and may also be different from the one or more second SFs.

[0406] In some embodiments, the method further comprises:

[0407] Sending a subscription request message to the second SF, where the subscription request message is used to subscribe to notification information about changes in communication and / or perception capabilities;

[0408] When the notification information sent by the second SF is received, the second SF is reselected.

[0409] Specifically, the first SF can subscribe to notification information of changes in communication and / or perception capabilities from the second SF, so that when the communication and / or perception capabilities of the second SF change (for example, the load is too large or the perception area changes, resulting in failure to meet the perception requirements, etc.), the first SF can promptly select a new second SF.

[0410] In some embodiments, the subscription request information may include a parameter threshold for triggering the notification information. For example, the parameter threshold may include a threshold corresponding to a parameter such as load or sensing area. When the threshold is exceeded, the second SF sends the notification information.

[0411] In some embodiments, the notification information may include parameters that do not meet the communication and / or perception requirements.

[0412] For example, if the second SF does not meet the perception requirements due to excessive load or a change in the perception area, the second SF may send a notification message to the first SF and indicate the parameters (such as load, perception area, etc.) that do not meet the communication and / or perception requirements in the notification message.

[0413] In some embodiments, the method further comprises:

[0414] Send indication information to the control plane network element, where the indication information is used to indicate that the first SF needs to be changed and / or the second SF needs to be changed.

[0415] Specifically, when the first SF determines that the first SF needs to be changed, or the second SF needs to be changed, or the first SF and the second SF need to be changed, the first SF can send indication information to the control plane network element. After the control plane network element receives the indication information, it can reselect the first SF and / or the second SF based on the indication information, for example, according to DNAI, S-NSSAI, load, target area information or target UE location information. Reselect the first SF and / or the second SF.

[0416] In some embodiments, the method further comprises:

[0417] When the first SF acts as a sink node, it processes the received sensing data to generate a sensing result, and opens the sensing result to the target receiving end.

[0418] Specifically, when the first SF is an SF without CU separation, the first SF can receive and process the perception data. When the first SF serves as a sink node, the first SF can process the received perception data to generate a perception result and open the perception result to the target receiving end.

[0419] In some embodiments, the method further comprises:

[0420] When the first SF does not serve as a sink node, the following processing is performed on the received sensing data:

[0421] Send the received sensing data to the sink node; or,

[0422] Process the received sensing data and send it to the sink node; or,

[0423] The received perception data is processed to generate perception results, and the perception results are opened to the target receiving end.

[0424] Specifically, when the first SF is an SF without CU separation, the first SF can receive and process the perception data. When the first SF does not serve as a sink node, after receiving the perception data, the first SF can have multiple different processing methods.

[0425] For example, the first SF may directly send the received sensing data to the sink node, that is, directly forward the received sensing data.

[0426] For another example, the first SF may process the received perception data and then send the processed data to the sink node, that is, process the received perception data to generate intermediate data, and then send the intermediate data to the sink node.

[0427] For another example, the first SF may process the received perception data to generate a perception result, and directly open the perception result to the target receiving end.

[0428] FIG6 is a second flow chart of a method for deploying an awareness service according to an embodiment of the present disclosure. The method may be applied to a second SF. As shown in FIG6 , the method includes the following steps:

[0429] Step 600: Receive perception data processing rules.

[0430] Step 601: Process the received perception data based on the perception data processing rules.

[0431] Specifically, in the embodiment of the present disclosure, the second SF may receive the perception data processing rule sent by the first SF or the control plane network element, and process the received perception data based on the perception data processing rule.

[0432] In some embodiments, after receiving the first perception request sent by the control plane network element, the first SF may determine one or more second SFs based on the first perception request, and then send perception data processing rules to the one or more second SFs.

[0433] In some embodiments, the control plane network element may select one or more second SFs based on the sensing requirement, and send the sensing data processing rules to the one or more second SFs.

[0434] In the embodiments of the present disclosure, the first SF may be a CU-integrated SF or SF-C, and the second SF may be a CU-integrated SF or SF-U. The one or more second SFs may all be CU-integrated SFs, all SF-Us, or some may be CU-integrated SFs and some may be SF-Us, without limitation in the embodiments of the present disclosure.

[0435] In the embodiments of the present disclosure, the control plane network element may be any control plane network element in the core network, and is not specifically limited here. In some embodiments, the control plane network element may include an AMF or a consumer network element of a perception service, wherein the consumer network element of the perception service may include an NWDAF, PCF, LMF, etc.

[0436] In some embodiments, the perception data processing rules include one or more of the following:

[0437] (1) Data processing method: The data processing method may include direct forwarding, generating intermediate data, or generating final perception results.

[0438] (2) Address information of the sink node. This address information may include, for example, an IP address, a port number, etc.

[0439] (3) Address information of the target receiving end. The target receiving end may be, for example, an AF, an AS, a UE, a NF, a consumer network element that perceives the service, etc. The address information may include, for example, an IP address, a port number, etc.

[0440] (4) Sink node indication: The sink node indication is information indicating whether the SF receiving the sensing data processing rule is a sink node.

[0441] (5) Data collection requirements: The data collection requirements may include, for example, the type of data being sensed, data accuracy, the time it takes to collect data, the time it takes to provide data, etc.

[0442] (6) Perception requirements: The perception requirements may include, for example, perception accuracy, perception resolution, perception precision, frame rate, perception time, target area information, QoS requirements, and perceived target information.

[0443] In the method for deploying perception services provided by the embodiments of the present disclosure, the second SF can process the perception data based on the perception data processing rules sent by the first SF or the control plane network element, so that the perception service can be uniformly managed by the core network, and the SF-U / SF that meets different capability requirements can be flexibly deployed on demand. At the same time, it supports multi-SF-U / SF collaboration, which can support application scenarios with low transmission latency and information confidentiality requirements, and realize load balancing and reasonable resource allocation on the SF-U / SF.

[0444] In some embodiments, the received sensory data is processed based on the sensory data processing rules, including:

[0445] When the second SF is determined as the sink node based on the perception data processing rule, the following processing is performed:

[0446] Process the received perception data to generate a perception result, and open the perception result to the target receiving end; or,

[0447] The received perception data is sent to SF-C, which is used to generate perception results and then open them to the target receiving end.

[0448] Specifically, after receiving the perception data processing rule, the second SF may determine whether to serve as a sink node based on the perception data processing rule. For example, if the perception data processing rule includes a sink node indication, or the sink node indication is set to TRUE, or does not include sink node address information, the second SF may determine that it serves as a sink node.

[0449] In some embodiments, when the second SF serves as a sink node, after receiving the sensing data, the second SF may process the received sensing data to generate a sensing result, and open the sensing result to a target receiving end.

[0450] In some embodiments, when the second SF serves as a sink node and is a type-2 SF-U, after receiving the perception data, the second SF may send the received perception data to the SF-C, which generates a perception result and then opens it to the target receiving end.

[0451] In some embodiments, the received sensory data is processed based on the sensory data processing rules, including:

[0452] If it is determined based on the sensing data processing rule that the second SF is not a sink node, the following processing is performed:

[0453] Send the received sensing data to the sink node; or,

[0454] Process the received sensing data and send it to the sink node; or,

[0455] Process the received perception data to generate a perception result, and open the perception result to the target receiving end; or,

[0456] The received perception data is sent to SF-C, which is used to generate perception results and then open them to the target receiving end.

[0457] Specifically, after receiving the perception data processing rules, the second SF can determine whether it serves as a sink node based on the perception data processing rules. For example, if the perception data processing rules do not include a sink node indication, or the sink node indication is set to FALSE, or include sink node address information, the second SF can determine that it does not serve as a sink node. If the second SF does not serve as a sink node, the second SF can use various different processing methods after receiving the perception data.

[0458] For example, the second SF may directly send the received sensing data to the sink node, that is, directly forward the received sensing data.

[0459] For another example, the second SF may process the received perception data and then send it to the sink node, that is, process the received perception data to generate intermediate data, and then send the intermediate data to the sink node.

[0460] For another example, the second SF may process the received perception data to generate a perception result, and directly open the perception result to the target receiving end.

[0461] For another example, the second SF is SF-U of type 2. After receiving the perception data, the second SF can send the received perception data to SF-C, and SF-C generates a perception result and opens it to the target receiving end.

[0462] In some embodiments, the method further comprises:

[0463] Send the second registration information to the NRF. The second registration information includes one or more of the following:

[0464] The service area of ​​the second SF, the perception capability of the second SF, the DNAI supported by the second SF, the S-NSSAI supported by the second SF, the type of data that can be collected by the second SF, the data collection delay supported by the second SF, and the data accuracy supported by the second SF.

[0465] Specifically, the second SF can register its own information with the NRF, for example, the service area of ​​the second SF, the perception capability of the second SF, the DNAI supported by the second SF, the S-NSSAI supported by the second SF, the type of data that can be collected by the second SF, the data collection delay supported by the second SF, the data accuracy supported by the second SF, and other information, so that other network elements can discover the second SF through the NRF when needed.

[0466] In some embodiments, the method further comprises:

[0467] Receiving a subscription request message, the subscription request message being used to subscribe to notification messages regarding changes in communication and / or perception capabilities;

[0468] In case the communication and / or sensing capabilities of the second SF change, a notification message is sent.

[0469] Specifically, the first SF or the control plane network element can subscribe to notification information of changes in communication and / or perception capabilities from the second SF, so that when the communication and / or perception capabilities of the second SF change (for example, the load is too large or the perception area changes, resulting in failure to meet the perception requirements, etc.), a new second SF can be selected in time.

[0470] In some embodiments, the subscription request information may include a parameter threshold for triggering the notification information. For example, the parameter threshold may include a threshold corresponding to a parameter such as load or sensing area. When the threshold is exceeded, the second SF sends the notification information.

[0471] The second SF may send notification information when its communication and / or perception capabilities change. In some embodiments, the notification information may include parameters that do not meet the communication and / or perception requirements.

[0472] For example, if the second SF does not meet the perception requirements due to excessive load or a change in the perception area, the second SF may send a notification message to the first SF and indicate the parameters (such as load, perception area, etc.) that do not meet the communication and / or perception requirements in the notification message.

[0473] In some embodiments, the method further comprises:

[0474] Receive a second perception request sent by the control plane network element, where the second perception request includes one or more of the following: information of the first SF, perception requirements, and data collection requirements.

[0475] Specifically, the control plane network element can select one or more second SFs according to the perception requirements, and then send a second perception request to the one or more second SFs. The second perception request may include information of the first SF (for example, the identifier of the first SF, IP address, etc.), perception requirements, data collection requirements, etc.

[0476] In some embodiments, the AF, AS, UE or NF may initiate a perception request, and the AF / AS / UE / NF sends the perception requirement to the control plane network element. The control plane network element selects a second SF based on the perception requirement, and then sends a second perception request to the second SF.

[0482] The control plane network element may select a first SF according to the perception requirement, and then send a first perception request to the first SF.

[0483] In some embodiments, the AF, AS, UE or NF may initiate a perception request, and the AF / AS / UE / NF sends the perception requirement to the control plane network element. The control plane network element selects the first SF according to the perception requirement, and then sends a first perception request to the first SF.

[0484] In some embodiments, the control plane network element (such as a consumer network element of the perception service) may select the first SF when it has a perception requirement, and then send a first perception request to the first SF.

[0488] In some embodiments, the first perception request includes one or more of the following: perception accuracy, perception resolution, frame rate, perception time, target area information, QoS requirements, and perceived target information.

[0489] In the method for deploying a perception service provided by the embodiments of the present disclosure, a control plane network element can select a first SF based on perception requirements and send a first perception request to the first SF. This allows the perception service to be uniformly managed by the core network, and enables flexible on-demand deployment of SFs that meet different capability requirements. This not only supports application scenarios requiring low transmission latency and information confidentiality, but also achieves load balancing and reasonable resource allocation on the SFs.

[0490] In some embodiments, the first perception request may also include information of one or more second SFs, which may be the identifier, IP address, etc. of the SF.

[0491] In some embodiments, the method further comprises:

[0492] One or more second SFs are determined based on the perceived need.

[0493] Specifically, when selecting the first SF, the control plane network element may also select one or more second SFs according to the sensing requirement. The control plane network element may include information of the one or more second SFs in the first sensing request and send it to the first SF.

[0494] In some embodiments, determining one or more second SFs based on the perceived demand includes:

[0495] Sending a first network element discovery request message to the NRF based on the sensing requirement, where the first network element discovery request message includes one or more of the following: DNAI, S-NSSAI, area information, and sensing type;

[0496] A first network element discovery response message sent by the NRF is received, where the first network element discovery response message includes information about one or more second SFs.

[0497] For example, the control plane network element can query the NRF through the network element discovery service for information about one or more second SFs that can match the perception requirements based on the perception request initiated by the AF / AS / UE / NF or its own requirements for perception services. The information can be the SF's identifier, IP address, port number, etc.

[0498] In some embodiments, the method further comprises:

[0499] A second perception request is sent to one or more second SFs, where the second perception request includes one or more of the following: information of the first SF, perception requirements, and data collection requirements.

[0500] Specifically, after the control plane network element determines one or more second SFs, it can also send a second perception request to the one or more second SFs. The second perception request may include information of the first SF (for example, the identifier of the first SF, IP address, etc.), perception requirements, data collection requirements, etc.

[0501] In some embodiments, the method further comprises:

[0502] The sensing data processing rules are sent to one or more second SFs.

[0503] Specifically, after the control plane network element determines one or more second SFs, it may also send perception data processing rules to the one or more second SFs, and the second SFs may process the received perception data based on the received perception data processing rules.

[0504] In some embodiments, the perception data processing rules include one or more of the following:

[0505] (1) Data processing method: The data processing method may include direct forwarding, generating intermediate data, or generating final perception results.

[0506] (2) Address information of the sink node. This address information may include, for example, an IP address, a port number, etc.

[0507] (3) Address information of the target receiving end. The target receiving end may be, for example, an AF, an AS, a UE, a NF, a consumer network element that perceives the service, etc. The address information may include, for example, an IP address, a port number, etc.

[0508] (4) Sink node indication: The sink node indication is information indicating whether the SF receiving the sensing data processing rule is a sink node.

[0509] (5) Data collection requirements: The data collection requirements may include, for example, the type of data being sensed, data accuracy, the time it takes to collect data, the time it takes to provide data, etc.

[0510] (6) Perception requirements: The perception requirements may include, for example, perception accuracy, perception resolution, perception precision, frame rate, perception time, target area information, QoS requirements, and perceived target information.

[0511] In some embodiments, the method further comprises:

[0512] Sending a subscription request message to the second SF, where the subscription request message is used to subscribe to notification information about changes in communication and / or perception capabilities;

[0513] When the notification information sent by the second SF is received, the second SF is reselected.

[0514] Specifically, the control plane network element can subscribe to notification information of changes in communication and / or perception capabilities from the second SF, so that when the communication and / or perception capabilities of the second SF change (for example, the load is too large or the perception area changes, resulting in failure to meet the perception requirements, etc.), the control plane network element can promptly select a new second SF.

[0515] In some embodiments, the subscription request information may include a parameter threshold for triggering the notification information. For example, the parameter threshold may include a threshold corresponding to a parameter such as load or sensing area. When the threshold is exceeded, the second SF sends the notification information.

[0516] In some embodiments, the notification information may include parameters that do not meet the communication and / or perception requirements.

[0517] For example, if the second SF does not meet the perception requirements due to excessive load or a change in the perception area, the second SF can send a notification message to the control plane network element and indicate the parameters that do not meet the communication and / or perception requirements (such as load, perception area, etc.) in the notification message.

[0519] Upon receiving the indication information sent by the first SF or determining that the second SF needs to be reselected, reselect the first SF and / or the second SF;

[0520] The indication information is used to indicate that the first SF needs to be changed and / or the second SF needs to be changed.

[0521] Specifically, when the first SF determines that the first SF needs to be changed, or the second SF needs to be changed, or the first SF and the second SF need to be changed, the first SF can send indication information to the control plane network element. After the control plane network element receives the indication information, it can reselect the first SF and / or the second SF based on the indication information, for example, according to DNAI, S-NSSAI, load, target area information or target UE location information. Reselect the first SF and / or the second SF.

[0522] The control plane network element may also reselect the first SF and / or the second SF when it determines that the second SF needs to be reselected. For example, when the UE moves to a new location and has moved out of the service area of ​​the original second SF, the control plane network element needs to reselect the second SF.

[0523] FIG8 is a fourth flow chart of a method for deploying an awareness service according to an embodiment of the present disclosure. The method can be applied to NRF. As shown in FIG8 , the method includes the following steps:

[0524] Step 800: Receive and store first registration information sent by the first SF, where the first registration information includes one or more of the following: the service area of ​​the first SF and the perception capability of the first SF; and / or receive and store second registration information sent by the second SF, where the second registration information includes one or more of the following: the service area of ​​the second SF, the perception capability of the second SF, the DNAI supported by the second SF, the S-NSSAI supported by the second SF, the type of data that can be collected by the second SF, the data collection delay supported by the second SF, and the data accuracy supported by the second SF.

[0525] Specifically, the first SF may register its own information with the NRF, for example, information such as the service area of ​​the first SF, the sensing capability of the first SF (such as the supported sensing methods), etc., so that other network elements can discover the first SF through the NRF when needed.

[0526] The second SF can register its own information with the NRF, for example, the service area of ​​the second SF, the perception capability of the second SF, the DNAI supported by the second SF, the S-NSSAI supported by the second SF, the type of data that the second SF can collect, the data collection delay supported by the second SF, the data accuracy supported by the second SF, and other information, so that other network elements can discover the second SF through the NRF when needed.

[0527] After receiving the registration information of the first SF and / or the second SF, the NRF stores the registration information for use in subsequent network element discovery.

[0529] Specifically, when the first SF is locally configured with information of the second SF, in addition to registering the information of the first SF itself, the first SF may also register the information of the second SF with the NRF.

[0530] In the method for deploying an awareness service provided by the embodiment of the present disclosure, the NRF can receive and store the registration information of the first SF and / or the second SF, so that the first SF or the control plane network element can query the NRF for the first SF and / or the second SF as needed, thereby realizing flexible on-demand deployment of SF-U / SF that meets different capability requirements.

[0534] Specifically, when the first SF or the control plane network element needs to select the second SF, it can send a first network element discovery request message to the NRF as needed, and the message includes DNAI, S-NSSAI, area information, perception type and other information.

[0535] After the NRF receives the first network element discovery request message, it can query the registration information of the second SF based on the DNAI, S-NSSAI, area information, perception type and other information contained in the message, so as to determine the matching second SF. Then, the NRF can reply to the first network element discovery response message, which carries information of one or more second SFs.

[0536] In some embodiments, the method further comprises:

[0537] receiving a second network element discovery request message, where the second network element discovery request message includes one or more of the following: area information and a perception type;

[0538] A second network element discovery response message is sent, where the second network element discovery response message includes information about the first SF.

[0539] Specifically, when the control plane network element needs to select the first SF, it can send a second network element discovery request message to the NRF as needed, where the message includes information such as area information and perception type.

[0540] After receiving the second network element discovery request message, the NRF can query the registration information of the first SF according to the area information, perception type and other information contained in the message, so as to determine the matching first SF. Then the NRF can reply with the second network element discovery response message, which carries the information of the first SF.

[0541] The methods provided in the various embodiments of the present disclosure are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.

[0542] The following describes the methods provided in the above embodiments of the present disclosure by using examples of specific application scenarios.

[0543] Based on the functions of SF-U, SF-U can be divided into two categories:

[0544] Type 1: Responsible for collecting and analyzing the perception measurement data generated by the terminal or base station, obtaining the final perception results, and opening them to the UE or application, that is, performing data collection and data perception / computation analysis.

[0545] Type 2: Responsible for collecting perception measurement data and reporting the perception measurement data to SF-C (SF-C analyzes the perception measurement data to obtain perception results and opens them to UE or application), that is, only performs data collection, and does not perform data perception / computation analysis.

[0546] Figure 9 is a schematic diagram of a distributed deployment architecture for a perception service provided by an embodiment of the present disclosure. Part (a) of Figure 9 illustrates an architecture with CU separation, while part (b) of Figure 9 illustrates an architecture with CU integration. The following examples may be based on the architecture shown in Figure 9.

[0547] Example 1:

[0548] This example describes the AF / AS / UE / NF-triggered perception process. The AMF discovers the appropriate SF-C and SF-U based on the perception request, and sends the perception data processing rules to the SF-U via the SF-C, thus enabling the collection, processing, and disclosure of perception data. The SF-U is type 1.

[0549] FIG10 is a diagram of network element interaction in Example 1 provided by an embodiment of the present disclosure. As shown in FIG10 , the main process includes:

[0550] 1. AF / AS / UE initiates a perception request. The AMF receives the perception request, which carries the service type and service requirements (perception resolution, perception accuracy, frame rate, duration, target area information, latency, and perceived target information).

[0551] 2. AMF obtains SF-C (and SF-U) registration information from NRF.

[0552] 3. The AMF selects an SF-C based on the target area information or target UE location information, and the SF-C's service area, sensing capability (e.g., sensing accuracy), QoS requirement (e.g., sensing delay), load, sensing time, etc. Optionally, the AMF selects an SF-U based on the DNAI and S-NSSAI, load, target area information or target UE location information, the SF-U's service area, sensing capability (e.g., sensing accuracy), QoS requirement (e.g., sensing delay), load, sensing time, etc.

[0553] 4a. The AMF sends a sensing request to the SF-C. The sensing request includes SF-U information, such as the SF-U identifier and IP address. The sensing request also includes sensing requirements, such as sensing accuracy, sensing resolution, frame rate, sensing time, target area information, QoS requirements (e.g., latency), and sensed target information.

[0554] 4b. (Optional) The AMF sends a sensing request to the SF-U. The sensing request includes SF-C information, such as the SF-C identifier and IP address. The sensing request also includes sensing requirements, such as sensing accuracy, sensing resolution, frame rate, sensing time, target area information, QoS requirements (e.g., latency), and sensed target information. The sensing request also includes data collection requirements, such as sensing data type, data accuracy, data collection time, and data provision time.

[0555] 5. (Optional) If the AMF does not select an SF-U in step 3, the SF-C selects an SF-U based on the DNAI, S-NSSAI, load, target area information or target UE location information, SF-U's service area, sensing capability (e.g., sensing accuracy), QoS requirements (e.g., sensing latency), load, sensing time, etc. The SF-C may obtain the SF-U information by requesting the NRF or through local configuration information.

[0556] 6. The SF-C establishes a connection with the SF-U and sends the sensing data processing rules to the SF-U. The rules include one or more of the following: data processing method (direct forwarding, generation of intermediate data, or generation of final results); sink node address information (IP address and / or port number); target receiver address (IP address and / or port number of the UE / NF / AF / AS); sink node indication; data collection requirements (e.g., sensing data type, data accuracy, data collection time, data provision time). Furthermore, the sensing policy is sent to the SF-U, including sensing requirements, such as sensing accuracy, sensing resolution, frame rate, sensing time, target area information, QoS requirements (e.g., latency), and sensed target information.

[0557] 7. Select sensing nodes based on existing technologies and configure sensing measurements for the sensing nodes.

[0558] 8. The perception node (UE or RAN) can send the perception data to the SF-C / SF-U through the control plane or the user plane. The SF directly opens the processed perception results to the AF / AS, or opens them to the AF / AS through the NEF / local NEF (L-NEF), or sends the perception results to the UE through the AMF.

[0559] Example 2:

[0560] This example describes the AF / AS / UE / NF-triggered perception process. The AMF discovers the appropriate SF-C and SF-U based on the perception request, and sends the perception data processing rules to the SF-U via the SF-C, thus enabling the collection, processing, and disclosure of perception data. The SF-U is type 2.

[0561] FIG11 is a diagram of network element interaction in Example 2 provided by an embodiment of the present disclosure. As shown in FIG11 , the main process includes:

[0562] 1. AF / AS / UE initiates a perception request. The AMF receives the perception request, which carries the service type and service requirements (perception resolution, perception accuracy, frame rate, duration, target area information, latency, and perceived target information).

[0563] 2. AMF obtains SF-C (and SF-U) registration information from NRF.

[0564] 3. The AMF selects an SF-C based on the target area information or target UE location information, and the SF-C's service area, sensing capability (e.g., sensing accuracy), QoS requirement (e.g., sensing delay), load, sensing time, etc. Optionally, the AMF selects an SF-U based on the DNAI and S-NSSAI, load, target area information or target UE location information, the SF-U's service area, sensing capability (e.g., sensing accuracy), QoS requirement (e.g., sensing delay), load, sensing time, etc.

[0565] 4a. The AMF sends a sensing request to the SF-C. The sensing request includes SF-U information, such as the SF-U identifier and IP address. The sensing request also includes sensing requirements, such as sensing accuracy, sensing resolution, frame rate, sensing time, target area information, QoS requirements (e.g., latency), and sensed target information.

[0566] 4b. (Optional) The AMF sends a sensing request to the SF-U. The sensing request includes information about the SF-C, such as the SF-C identifier and IP address. The sensing request also includes data collection requirements, such as the type of sensing data, data accuracy, data collection time, and data provision time.

[0567] 5. (Optional) If the AMF does not select an SF-U in step 3, the SF-C selects an SF-U based on the DNAI, S-NSSAI, load, target area information or target UE location information, SF-U's service area, sensing capability (e.g., sensing accuracy), QoS requirements (e.g., sensing latency), load, sensing time, etc. The SF-C may obtain the SF-U information by requesting the NRF or through local configuration information.

[0568] 6. SF-C establishes a connection with SF-U and sends perception data processing rules to SF-U. The rules include one or more of the following: data processing method (direct forwarding or generation of intermediate data or generation of final results); aggregation node address information (IP address and / or port number); target receiving end address (IP address and / or port number of UE / NF / AF / AS); aggregation node indication; data collection requirements (for example, perception data type, data accuracy, data collection time, data provision time).

[0569] 7. Select sensing nodes based on existing technologies and configure sensing measurements for the sensing nodes.

[0570] 8. The perception node (UE or RAN) can send the perception data to the SF-C / SF-U through the control plane or the user plane. The SF-U sends the collected perception data to the SF-C. The SF-C analyzes and processes the perception data to obtain the perception results and then opens them to the AF / AS, or opens them to the AF / AS through the NEF / L-NEF, or sends the perception results to the UE through the AMF.

[0571] Example 3:

[0572] This example introduces the selection of multiple SF-Us to collaboratively process perception data. In certain scenarios, when multiple perception nodes (RAN or UE) are required to collaboratively obtain perception data, due to the limitations of the perception nodes and SF-U service areas, it is impossible for all perception nodes to send data to the same SF-U. In addition, in some scenarios, one of the RAN nodes will be set as an aggregation node, and the aggregation node RAN will report the data to the SF-U. However, if the amount of data is large, it is easy to cause the aggregation node RAN to be overloaded, and the processing capability requirements of the RAN are also very high. This example solution proposes that there is no need to aggregate data at the perception node, but through the distributed deployment of SF-U, each perception node sends the perception data to the SF-U to which it is connected. After receiving the perception data, the SF-U has three processing methods: 1) Each SF-U processes the perception data separately, and then sends the processed intermediate data / final data to a sink node SF-U for aggregation and processing; 2) The SF-U generates the final data (perception result) through processing and directly opens it to the AF / AS / UE / NF; 3) The SF-U directly sends the received raw perception data to the sink node SF-U for aggregation and processing. The SF-U can be type one or type two. For example, all SF-Us can be type one; or all SF-Us can be type two; or the sink node SF-U can be type one, and the other SF-Us can be type two, and so on. In this example, all type one SF-Us can also be replaced with SF.

[0573] FIG12 is a diagram of network element interaction in Example 3 provided by an embodiment of the present disclosure. As shown in FIG12 , the main process includes:

[0574] 1. The sensing node (RAN or UE) sends the sensing data to the SF-U to which it is connected.

[0575] 2. After receiving the sensor data, the SF-U processes the sensor data based on the sensor data processing rules configured by the SF-C. The processing methods include:

[0576] 1) If the sink node indication is included or is set to TRUE, or if the sink node address information is not included, it is determined as the sink node. The node receives raw perception data / intermediate data (e.g., point cloud data) / final data sent by other SF-Us and sensing nodes, processes them accordingly, and opens the final integrated perception results to the target receiving end AF / AS / UE / NF, as shown in step 2b of Figure 12.

[0577] 2) If the sink node indication is not included or is set to FALSE, or if the sink node address is included, it is determined not to be a sink node. The SF-U receives raw perception data, intermediate data, or final data sent by other SF-Us and perception nodes, processes the generated intermediate data / final data accordingly, and sends it to the sink node, as shown in step 2a of Figure 12. Alternatively, the SF-U processes the generated final data (perception result) and directly opens it to the target receiving end AF / AS / UE / NF, as shown in step 2c of Figure 12.

[0578] If it is type 2 SF-U, the collected perception data needs to be sent to SF-C first. SF-C will analyze and process the perception data to obtain the perception results and then open them to AF / AS / UE / NF.

[0579] Example 4:

[0580] This example describes that when a SF-U reports changes in its communication / perception capabilities to the AMF / SF-C (for example, excessive load, changes in the perception area resulting in unmet perception requirements, etc.), the AMF / SF-C is triggered to reselect the SF-U. Alternatively, the SF-C determines that the SF-C itself needs to be changed or the SF-U needs to be changed, and then sends an indication message to the AMF. The AMF determines that the SF-C and / or SF-U need to be reselected based on the indication of the SF-C or the AMF based on the UE location information. In this example, the SF-U can also be replaced by the SF, and then there is no SF-C subscription.

[0581] FIG13 is a diagram of network element interaction in Example 4 provided by an embodiment of the present disclosure. As shown in FIG13 , the main process includes:

[0582] 1a. (Optionally) AMF / SF-C subscribes to notification information of changes in communication and perception capabilities from SF-U (the SF-U may be referred to as the source SF-U). The subscription request information may include thresholds corresponding to parameters such as load and perception area. When this threshold is exceeded, the SF-U sends a notification message.

[0583] 1b. (Optionally) If the SF-C determines that the SF-C itself needs to be changed or the SF-U needs to be changed, it sends an indication message to the AMF.

[0584] 2a. (Optionally) SF-U sends information about changes in its communication / perception capabilities to AMF / SF-C. The information may include parameters that do not meet the communication / perception requirements, such as load, area, etc.

[0585] The AMF / SF-C reselects the SF-U (which may be referred to as the target SF-U) based on DNAI, S-NSSAI, load, target area information, or target UE location information.

[0586] 2b. (Optional) The AMF, based on the indication of the SF-C (if 1b is performed), or the AMF determines that the SF-U needs to be reselected (for example, based on the UE moving to a new location and has moved out of the service area of ​​the original SF-U), reselects the SF-C and / or SF-U according to DNAI, S-NSSAI, load, target area information or target UE location information.

[0587] The subsequent steps are the same as steps 5-9 in Example 1.

[0588] Example 5:

[0589] This example describes how to register SF-C and SF-U with NRF and how to discover SF-U and SF-C through NRF.

[0590] Example 5a: Register with NRF.

[0591] Method 1: SF-C and SF-U register with NRF separately.

[0592] 1) SF-U sends a registration request message to NRF, which includes one or more of the following: service area, sensing capability (sensing mode, supported sensing data reporting mode, sensing delay, sensing accuracy, IP address and / or port number information, etc.), supported DNAI(s), S-NSSAI, type of collectible data, data collection delay, and data accuracy.

[0593] 2) SF-C sends a registration request message to NRF, which includes one or more of the following information: registration service area, sensing capability (sensing mode, etc.).

[0594] The service areas registered for SF-U and SF-C may be different.

[0595] Method 2: SF-C locally configures SF-U information, and registers its own information with NRF, and optionally registers SF-U information.

[0596] Example 5b: Discovering SF-U through NRF.

[0597] When NF (such as AMF, SF-C) needs to select SF-U, it obtains SF-U information by interacting with NRF. Figure 14 is an example 5b network element interaction diagram provided by the embodiment of the present disclosure. As shown in Figure 14, its main process includes:

[0598] 1. NF (AMF / SF-C) sends a first network element discovery request message (Nnrf_NFDiscoveryRequest) to NRF, which includes one or more of DNAI, S-NSSAI, area information, and perception type.

[0599] 2. The NRF sends a first network element discovery response message (Nnrf_NFDiscoveryResponse) to the NF, which includes one or more of the SF-U identifier, IP address, and port number.

[0600] Example 5c: Discovery of SF-C by NRF.

[0601] When NF (such as AMF) needs to select SF-C, it obtains SF-C information by interacting with NRF. The process is similar to that of discovering SF-U, mainly including:

[0602] 1. NF (AMF) sends a second network element discovery request message (Nnrf_NFDiscoveryRequest) to NRF, which includes one or more of area information and perception type.

[0603] 2. The NRF sends a second network element discovery response message (Nnrf_NFDiscoveryResponse) to the NF, which includes one or more of the SF-C identifier, IP address, and port number.
