[0323] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0324] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0325] In the embodiments of the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0326] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0327] In order to facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical contents related to the embodiments of the present application are first introduced.

[0328] 1. 5G synaesthesia fusion.

[0329] Communication and perception fusion realizes the unified design of communication and perception functions through signal joint design and / or hardware sharing. The perception in communication and perception fusion can be understood as a wireless perception technology based on the communication system, which transmits wireless signals to the target area or object and analyzes the received wireless signals to obtain the corresponding perception measurement information. Therefore, the wireless communication network naturally has wireless perception capabilities. The base station and terminal will have both communication and perception capabilities, and can provide perception services for perception applications, including intelligent transportation, drone supervision, national railway perimeter safety detection, smart home, public safety, health monitoring, environmental detection and other fields.

[0330] 2. 5G synaesthesia-integrated network architecture.

[0331] Considering the degree of coupling between the perception function and the existing functional modules in 5GC, the synaesthesia network architecture can be roughly divided into two types: tight coupling and loose coupling. The related technology proposes to add a new functional network element SF for perception in 5GC, which is mainly responsible for perception control and perception measurement data calculation. SF can include two logical perception functions SF-C and SF-U, where SF-C is the perception control plane function, and the control signaling between SF-C and the terminal (or user equipment, User Equipment, UE) and the radio access network (Radio Access Network, RAN) is transmitted through the access and mobility management function (Access and Mobility Management Function, AMF); SF-U is the perception user plane function, and the UE and RAN transmit the perception measurement data to SF-U. SF-C and SF-U may also be logically inseparable. The SF logical function can be combined with functions such as the location management function (Location Management Function, LMF), or the LMF can be directly enhanced to implement this function.

[0332] Figure 1 Schematic diagram of the tightly coupled synaesthesia network architecture provided for related technologies, Figure 2 A schematic diagram of a loosely coupled synaesthesia network architecture provided for related technologies. Figure 1 Part (a) in the figure is the CU non-separation architecture (i.e., no distinction between SF-C and SF-U) in the tightly coupled synaesthesia network architecture. Figure 1 Part (b) is the CU separation (i.e., SF-C and SF-U separation) architecture in the tightly coupled synaesthesia network architecture.

[0333] Figure 1 and Figure 2 The main network functions (NF) and interfaces involved are introduced as follows:

[0334] AMF: Access and mobility management function, responsible for registration, connection management, etc.

[0335] UPF: User Plane Function is an external protocol data unit (PDU) session node interconnected with the data network (DN) and is responsible for message routing and forwarding.

[0336] SMF: Session Management Function. Responsible for session establishment and deletion, user plane selection and control, and UE Internet Protocol (IP) address allocation.

[0337] AF: Application Function, interacts with the 3GPP core network to provide services. Based on the operator's deployment, the trusted AF can interact directly with the relevant NF, while the untrusted AF cannot interact directly with the NF, but should use the public framework through the Network Exposure Function (NEF).

[0338] NWDAF: Network Data Analytics Function, which can provide network analysis services based on the request data of network services.

[0339] PCF: Policy Control Function. Supports a unified policy framework to manage network behavior and provide policy rules for control plane NF execution.

[0340] NRF: Network Repository Function. Supports service discovery function.

[0341] UDM: Unified Data Management. Stores UE information, such as contract information, information about established PDU sessions, etc.

[0342] NEF: Network exposure function. Provides functions related to securely exposing the services and capabilities provided by the 3GPP network to external networks.

[0343] NSSF: Network Slice Selection Function. Determines the network slice instance that the UE is allowed to access based on the UE's slice selection auxiliary information, subscription information, etc.

[0344] AUSF: Authentication Server Function. Implements 3GPP and non-3GPP access authentication.

[0345] SF-C: Perception control plane function, control signaling between UE and RAN is transmitted through AMF.

[0346] SF-U: Perception user plane function. UE and RAN transmit perception measurement data to SF-U.

[0347] NS1: NS1 is a new interface between SF and AMF, which can transmit perception control signaling and perception measurement data.

[0348] 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.

[0349] NS3: NS3 is a new interface between SF and UDM, through which authentication or authorization can be implemented to obtain UE perception subscription information, service AMF information or other information.

[0350] NS4: NS4 is a new interface between SF and NWDAF. Through this interface, SF can work with NWDAF to complete artificial intelligence (AI) processing related to perception services.

[0351] NS5: NS5 is a new interface between SF and PCF. Through this interface, SF can pass information such as perception requirements, quality of service (QoS) requirements or perception results of perception services to PCF. PCF decides and generates policy control and charging (PCC) policies related to perception services.

[0352] 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 location information of the sensed UE.

[0353] NS7: A new interface is added between SF (or SF-U) and UPF. The 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 UPF. If the (R)AN is forwarded via UPF in the scenario where perception is performed, UPF needs to be modified to support data transmission at the (R)AN granularity.

[0354] NS8: A new interface is added between SF-C and SF-U, through which perception processing strategies can be transmitted and perception results can be reported.

[0355] N1, N2, N3, N4, N5, N6, N7, N8, N10, N12, N15, N22, N33, Uu, etc. are existing interfaces of traditional 5GC and will not be repeated here.

[0356] 3. Perception method.

[0357] Figure 3 Schematic diagram of the six basic sensing methods provided for related technologies, such as Figure 3 As shown in the figure, 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 sensing according to different sensing scenarios, sensing environments, sensing business requirements, etc.

[0358] 4. Perception process.

[0359] Figure 4 Example diagram of the perception process signaling interaction provided for related technologies, Figure 4 The example is the sensing process when the sensing mode is self-transmitting and self-receiving of the base station or base station A transmits and B receives under the CU separation architecture. The sensing processes of other sensing modes are similar and will not be described in detail. Figure 4 As shown, the main process includes:

[0360] Step 1: 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, while carrying the IP address and port number of the SF-U for receiving perception measurement data.

[0361] Step 2: RAN detects the perception measurement data and obtains the perception measurement data.

[0362] Step 3: RAN reports the sensing measurement data to SF-U.

[0363] Step 4: SF-U reports to SF-C that it has received the perception measurement data.

[0364] Related technologies have proposed architectures with CUs that do not separate or separate sensing functions, as well as sensing processes for different sensing methods. However, they 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 in information transmission, meet information confidentiality requirements, and reasonably allocate transmission resources.

[0365] Figure 5 One of the flow charts of the method for deploying awareness services provided in an embodiment of the present application, the method can be applied to the first SF, such as Figure 5 As shown, the method comprises the following steps:

[0366] Step 500: Receive a first perception request sent by a control plane network element.

[0367] Step 501: determine one or more second SFs based on a first perception request, and send perception data processing rules to the one or more second SFs.

[0368] Specifically, the first SF may be a CU-inseparable SF or SF-C, and the second SF may be a CU-inseparable SF or SF-U. The one or more second SFs may all be CU-inseparable SFs, or all be SF-Us, or some may be CU-inseparable SFs and some may be SF-Us, which is not limited in the embodiment of the present application.

[0369] In the embodiment of the present application, SF-U may include the following two types:

[0370] 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 the perception results to the UE or application, that is, Type 1 SF-U can perform functions such as data collection, data perception, calculation and analysis.

[0371] 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 the 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.

[0372] In the embodiment of the present application, the SF-Us in the one or more second SFs (if there are CU-separated SF-Us) 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 application is not limited thereto.

[0373] In some embodiments, SF may be LMF, for example, the perception function may be integrated with LMF, or LMF may be directly enhanced to realize the function.

[0374] In the embodiment of the present application, the control plane network element may be any control plane network element in the core network, and no specific limitation is made here. In some embodiments, the control plane network element may include an AMF or a consumer network element of the perception service, wherein the consumer network element of the perception service may include an NWDAF, a PCF, a LMF, etc.

[0375] 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.

[0376] In some embodiments, the perception request may be initiated by AF, application server (AS), UE or NF, and 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.

[0377] In some embodiments, the control plane network element (such as a consumer network element of a perception service) may select the first SF when it has a perception requirement, and then send a first perception request to the first SF.

[0378] 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.

[0379] 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 feed back perception data), and feedback duration (i.e., how long it takes to feed back perception data).

[0380] In some embodiments, the target area information includes information indicating the target area to be sensed, for example, the information may indicate a specific geographic area, one or more tracking area identifiers (TAI), one or more cell identifiers (Cell ID), etc.

[0381] In some embodiments, the sensed target may be a vehicle, and the sensed target information may include the vehicle type of the sensed vehicle, the vehicle identification of the sensed vehicle, the location information of the sensed vehicle, etc. Of course, this is only an example, and the sensed target may also be any other sensed object, and this application does not limit this.

[0382] In some embodiments, the first perception request may also include information of one or more second SFs, which may be an identifier, IP address, etc. of the SF.

[0383] 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.

[0384] In some embodiments, the perception data processing rules include one or more of the following:

[0385] (1) Data processing method: The data processing method may include, for example, direct forwarding, generating intermediate data, or generating final perception results.

[0386] (2) Address information of the aggregation node. The address information may include, for example, an IP address, a port number, etc.

[0387] (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.

[0388] (4) Sink node indication: The sink node indication is indication information used to indicate whether the SF receiving the sensing data processing rule is a sink node.

[0389] (5) Data collection requirements: The data collection requirements may include, for example, the type of data sensed, data accuracy, data collection time, data provision time, etc.

[0390] (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, perceived target information, etc.

[0391] 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.

[0392] 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.

[0393] For example, the first SF can query the NRF for information about one or more second SFs that can match the demand for perception service in the first perception request through the network element discovery service; 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.

[0394] In some embodiments, querying the NRF for information of one or more second SFs includes:

[0395] 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 (Data Network Access Identifier, DNAI), single network slice selection assistance information (Single Network Slice Selection Assistance Information, S-NSSAI), area information, and perception type (for example, it may be type one or type two described above);

[0396] A first network element discovery response message sent by the NRF is received, where the first network element discovery response message includes information of one or more second SFs, and the information may be an identifier, an IP address, a port number, etc. of the SF.

[0397] In the method for deploying a perception service provided in an embodiment of the present application, 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 a perception data processing rule to the one or more second SFs, 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, while supporting multi-SF-U / SF collaboration, which can not only support application scenarios with low transmission latency and information confidentiality requirements, but also realize load balancing and reasonable resource allocation on the SF-U / SF.

[0398] In some embodiments, the method further comprises:

[0399] Sending first registration information to the NRF, where the first registration information includes one or more of the following: a service area of ​​the first SF and a perception capability of the first SF.

[0400] Specifically, the first SF may register its own information with the NRF, for example, the service area of ​​the first SF, the sensing capability of the first SF (such as the supported sensing method), and other information, so that other network elements may discover the first SF through the NRF when needed.

[0401] In some embodiments, the first registration information also includes registration information of the second SF, and the registration information of the second SF includes one or more of the following: a service area of ​​the second SF, a perception capability of the second SF, a DNAI supported by the second SF, an S-NSSAI supported by the second SF, a type of data that can be collected by the second SF, a data collection delay supported by the second SF, and data accuracy supported by the second SF.

[0402] Specifically, when the first SF is locally configured with information of the second SF, in addition to registering information of the first SF itself, the first SF can also register 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.

[0403] In some embodiments, the method further comprises:

[0404] Sending a subscription request message to the second SF, where the subscription request message is used to subscribe to notification information of changes in communication and / or perception capabilities;

[0405] When the notification information sent by the second SF is received, the second SF is reselected.

[0406] Specifically, the first SF may 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 may select a new second SF in a timely manner.

[0407] 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, and when the threshold is exceeded, the second SF sends the notification information.

[0408] In some embodiments, the notification information may include parameters that do not meet the communication and / or perception requirements.

[0409] For example, if the second SF does not meet the perception requirement 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 in the notification message the parameters (such as load, perception area, etc.) that do not meet the communication and / or perception requirements.

[0410] In some embodiments, the method further comprises:

[0411] 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.

[0412] 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, reselect the first SF and / or the second SF according to DNAI, S-NSSAI, load, target area information, or target UE location information.

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

[0414] 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.

[0415] 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.

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

[0417] When the first SF does not serve as a sink node, the following processing is performed on the received sensing data:

[0418] Send the received sensing data to the sink node; or,

[0419] Process the received sensing data and send it to the sink node; or,

[0420] The received perception data is processed to generate perception results, and the perception results are opened to the target receiving end.

[0421] 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.

[0422] For example, the first SF may directly send the received sensing data to the aggregation node, that is, directly forward the received sensing data.

[0423] For another example, the first SF may process the received perception data and 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.

[0424] 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.

[0425] Figure 6 The second flow chart of the method for deploying the awareness service provided in the embodiment of the present application is as follows. The method can be applied to the second SF, such as Figure 6 As shown, the method comprises the following steps:

[0426] Step 600: Receive perception data processing rules.

[0427] Step 601: Process the received perception data based on the perception data processing rule.

[0428] Specifically, in an embodiment of the present application, the second SF may receive a 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.

[0429] 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.

[0430] 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.

[0431] In the embodiment of the present application, the first SF may be a CU-inseparable SF or SF-C, and the second SF may be a CU-inseparable SF or SF-U. The one or more second SFs may all be CU-inseparable SFs, or all be SF-U, or some may be CU-inseparable SFs and some may be SF-U, which is not limited in the embodiment of the present application.

[0432] In the embodiment of the present application, the control plane network element may be any control plane network element in the core network, and no specific limitation is made here. In some embodiments, the control plane network element may include an AMF or a consumer network element of the perception service, wherein the consumer network element of the perception service may include an NWDAF, a PCF, a LMF, etc.

[0433] In some embodiments, the perception data processing rules include one or more of the following:

[0434] (1) Data processing method: The data processing method may include, for example, direct forwarding, generating intermediate data, or generating final perception results.

[0435] (2) Address information of the aggregation node. The address information may include, for example, an IP address, a port number, etc.

[0436] (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.

[0437] (4) Sink node indication: The sink node indication is indication information used to indicate whether the SF receiving the sensing data processing rule is a sink node.

[0438] (5) Data collection requirements: The data collection requirements may include, for example, the type of data sensed, data accuracy, data collection time, data provision time, etc.

[0439] (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, perceived target information, etc.

[0440] In the method for deploying perception services provided in the embodiment of the present application, the second SF can process the perception data based on the perception data processing rule 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, while supporting multi-SF-U / SF collaboration, which can not only support application scenarios with low transmission latency and information confidentiality requirements, but also realize load balancing and reasonable resource allocation on the SF-U / SF.

[0441] In some embodiments, the received sensory data is processed based on the sensory data processing rule, including:

[0442] In the case where the second SF is determined as the sink node based on the sensing data processing rule, the following processing is performed:

[0443] Process the received perception data to generate a perception result, and open the perception result to the target receiving end; or,

[0444] The received perception data is sent to SF-C, which is used to generate the perception results and then open them to the target receiving end.

[0445] Specifically, after receiving the perception data processing rule, the second SF can 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 can determine that it serves as a sink node.

[0446] In some embodiments, when the second SF acts as a sink node, after receiving the perception data, the second SF may process the received perception data to generate a perception result, and open the perception result to the target receiving end.

[0447] In some embodiments, when the second SF acts as a sink node and is a type-two SF-U, after receiving the perception data, the second SF may send the received perception data to the SF-C, and the SF-C generates a perception result and then opens it to the target receiving end.

[0448] In some embodiments, the received sensory data is processed based on the sensory data processing rule, including:

[0449] When it is determined based on the sensing data processing rule that the second SF is not used as a sink node, the following processing is performed:

[0450] Send the received sensing data to the sink node; or,

[0451] Process the received sensing data and send it to the sink node; or,

[0452] Process the received perception data to generate a perception result, and open the perception result to the target receiving end; or,

[0453] The received perception data is sent to SF-C, which is used to generate the perception results and then open them to the target receiving end.

[0454] Specifically, after receiving the perception data processing rule, the second SF can determine whether it serves as a sink node based on the perception data processing rule. For example, if the perception data processing rule does not include a sink node indication, or the sink node indication is set to FALSE, or includes sink node address information, the second SF can determine that it does not serve as a sink node. In the case where the second SF does not serve as a sink node, the second SF can have a variety of different processing methods after receiving the perception data.

[0455] For example, the second SF may directly send the received sensing data to the aggregation node, that is, directly forward the received sensing data.

[0456] For another example, the second SF may process the received perception data and 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.

[0457] 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.

[0458] For another example, the second SF is SF-U of type two. After receiving the perception data, the second SF can send the received perception data to SF-C, and SF-C generates the perception result and then opens it to the target receiving end.

[0459] In some embodiments, the method further comprises:

[0460] Send the second registration information to the NRF, where the second registration information includes one or more of the following:

[0461] 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.

[0462] 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.

[0463] In some embodiments, the method further comprises:

[0464] Receiving a subscription request message, the subscription request message is used to subscribe to notification messages of changes in communication and / or perception capabilities;

[0465] In case the communication and / or sensing capabilities of the second SF change, a notification message is sent.

[0466] Specifically, the first SF or the control plane network element can subscribe to the notification information of the change of communication and / or perception capability from the second SF, so that when the communication and / or perception capability of the second SF changes (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.

[0467] 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, and when the threshold is exceeded, the second SF sends the notification information.

[0468] 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.

[0469] For example, if the second SF does not meet the perception requirement 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 in the notification message the parameters (such as load, perception area, etc.) that do not meet the communication and / or perception requirements.

[0470] In some embodiments, the method further comprises:

[0471] 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.

[0472] 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.

[0473] 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.

[0478] Specifically, in the embodiment of the present application, the control plane network element may be any control plane network element in the core network, and no specific limitation is made here. In some embodiments, the control plane network element may include an AMF or a consumer network element of the perception service, wherein the consumer network element of the perception service may include an NWDAF, a PCF, a LMF, etc.

[0479] 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.

[0480] In some embodiments, the perception request may be initiated by AF, 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.

[0481] In some embodiments, the control plane network element (such as a consumer network element of a perception service) may select the first SF when it has a perception requirement, and then send a first perception request to the first SF.

[0484] A second network element discovery response message sent by the NRF is received, where the second network element discovery response message includes information of the first SF, which may be an identifier, an IP address, a port number, etc. of the first SF.

[0485] 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.

[0486] In the method for deploying a perception service provided in an embodiment of the present application, the control plane network element can select a first SF based on the perception demand and send a first perception request to the first SF, so that the perception service can be uniformly managed by the core network, and SFs that meet different capability requirements can be flexibly deployed on demand, which can support application scenarios with low transmission latency and information confidentiality requirements, and realize load balancing on the SF and reasonable resource allocation.

[0487] In some embodiments, the first perception request may also include information of one or more second SFs, which may be an identifier, IP address, etc. of the SF.

[0488] In some embodiments, the method further comprises:

[0489] One or more second SFs are determined based on the perceived need.

[0490] Specifically, when selecting the first SF, the control plane network element may also select one or more second SFs according to the perception requirement. The control plane network element may include information of the one or more second SFs in the first perception request and send it to the first SF.

[0491] In some embodiments, determining one or more second SFs based on the perceived demand includes:

[0492] 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;

[0493] 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.

[0494] For example, the control plane network element can query the NRF for information about one or more second SFs that can match the perception requirements through the network element discovery service based on the perception request initiated by the AF / AS / UE / NF or its own demand for perception services. The information may be the SF's identifier, IP address, port number, etc.

[0495] In some embodiments, the method further comprises:

[0496] 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.

[0497] 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.

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

[0499] The sensing data processing rules are sent to one or more second SFs.

[0500] 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 SF may process the received perception data based on the received perception data processing rules.

[0501] In some embodiments, the perception data processing rules include one or more of the following:

[0502] (1) Data processing method: The data processing method may include, for example, direct forwarding, generating intermediate data, or generating final perception results.

[0503] (2) Address information of the aggregation node. The address information may include, for example, an IP address, a port number, etc.

[0504] (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.

[0510] When the notification information sent by the second SF is received, the second SF is reselected.

[0511] Specifically, the control plane network element can subscribe to notification information about 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.

[0512] 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, and when the threshold is exceeded, the second SF sends the notification information.

[0513] In some embodiments, the notification information may include parameters that do not meet the communication and / or perception requirements.

[0514] 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 control plane network element and indicate in the notification message the parameters (such as load, perception area, etc.) that do not meet the communication and / or perception requirements.

[0517] The indication information is used to indicate that the first SF needs to be changed and / or the second SF needs to be changed.

[0518] 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, reselect the first SF and / or the second SF according to DNAI, S-NSSAI, load, target area information, or target UE location information.

[0519] 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, the UE moves to a new location and has moved out of the service area of ​​the original second SF. At this time, the control plane network element needs to reselect the second SF.

[0520] Figure 8 The fourth flowchart of the method for deploying a sensing service provided in the embodiment of the present application is applicable to NRF, such as Figure 8 As shown, the method comprises the following steps:

[0521] Step 800, receiving and storing first registration information sent by the first SF, where the first registration information includes one or more of the following: a service area of ​​the first SF, a perception capability of the first SF; and / or receiving and storing second registration information sent by the second SF, where the second registration information includes one or more of the following: a service area of ​​the second SF, a perception capability of the second SF, a DNAI supported by the second SF, an S-NSSAI supported by the second SF, a type of data that can be collected by the second SF, a data collection delay supported by the second SF, and a data accuracy supported by the second SF.

[0522] Specifically, the first SF may register its own information with the NRF, for example, the service area of ​​the first SF, the sensing capability of the first SF (such as the supported sensing method), and other information, so that other network elements may discover the first SF through the NRF when needed.

[0523] 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.

[0526] 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.

[0527] In the method for deploying an awareness service provided in an embodiment of the present application, the NRF can receive and store 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.

[0528] In some embodiments, the method further comprises:

[0531] 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 according to demand, and the message includes DNAI, S-NSSAI, area information, perception type and other information.

[0532] After receiving the first network element discovery request message, the NRF can query the registration information of the second SF according to the DNAI, S-NSSAI, area information, perception type and other information contained in the message 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.

[0533] In some embodiments, the method further comprises:

[0534] 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 sensing type;

[0535] A second network element discovery response message is sent, where the second network element discovery response message includes information about the first SF.

[0536] 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 according to demand, and the message includes information such as area information and perception type.

[0537] 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 first SF that can be matched. Then the NRF can reply with the second network element discovery response message, which carries the information of the first SF.

[0538] The methods provided in the embodiments of the present application 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.

[0539] The following describes the methods provided in the above embodiments of the present application by using examples of specific application scenarios.

[0540] Based on the functions of SF-U, SF-U can be divided into two categories:

[0541] 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.

[0542] 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 the perception results and opens them to UE or application), that is, only performs data collection, and does not perform data perception / computation analysis.

[0543] Fig. 9 A schematic diagram of a distributed deployment architecture of a perception service provided in an embodiment of the present application. Fig. 9 Part (a) is the CU separation architecture. Fig. 9 Part (b) of the example is an architecture where the CU is not separated. Fig. 9 The architecture shown.

[0544] Example 1:

[0545] This example introduces the AF / AS / UE / NF triggered perception process. AMF discovers suitable SF-C and SF-U based on the perception request, and sends the perception data processing rules to SF-U through SF-C to realize the collection, processing and exposure of perception data. Among them, SF-U is type one.

[0546] Fig.10 The example 1 network element interaction diagram provided in the embodiment of the present application is as follows: Fig.10 As shown, the main process includes:

[0547] 1. AF / AS / UE initiates a perception request. AMF receives the perception request, which carries the service type, service requirements (perception resolution, perception accuracy, frame rate, duration, target area information, latency, perceived target information), etc.

[0548] 2. AMF obtains SF-C (and SF-U) registration information from NRF.

[0549] 3. AMF selects SF-C according to the target area information or target UE location information, and the service area, sensing capability (such as sensing accuracy), QoS requirement (such as sensing delay), load, sensing time, etc. of SF-C. Optionally, AMF selects SF-U according to DNAI and S-NSSAI, load, target area information or target UE location information, service area, sensing capability (such as sensing accuracy), QoS requirement (such as sensing delay), load, sensing time, etc. of SF-U.

[0550] 4a. AMF sends a perception request to SF-C. The perception request includes information of SF-U, such as the identifier and IP address of SF-U. The perception request also includes perception requirements, such as perception accuracy, perception resolution, frame rate, perception time, target area information, QoS requirements (e.g., latency), and perceived target information.

[0551] 4b. (Optionally) AMF sends a sensing request to SF-U, which includes information of SF-C, such as the identifier and IP address of SF-C. The sensing request also includes sensing requirements, such as sensing accuracy, sensing resolution, frame rate, sensing time, target area information, QoS requirements (such as latency), sensed target information, etc. The sensing request also includes data collection requirements, such as sensing data type, data accuracy, data collection time, data provision time, etc.

[0552] 5. (Optionally) If the AMF does not select an SF-U in step 3, the SF-C selects an SF-U based on DNAI, S-NSSAI, load, target area information or target UE location information, service area of ​​the SF-U, sensing capability (e.g., sensing accuracy), QoS requirements (e.g., sensing latency), load, sensing time, etc. The SF-C may obtain the information of the SF-U by requesting the NRF or through local configuration information.

[0553] 6. SF-C establishes a connection with SF-U and sends the sensing data processing rules to SF-U. The rules include one or more of the following: data processing mode (direct forwarding or generating intermediate data or generating 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, sensing data type, data accuracy, data collection time, data provision time). And sends the sensing strategy to SF-U, including sensing requirements, such as sensing accuracy, sensing resolution, frame rate, sensing time, target area information, QoS requirements (for example, latency), sensed target information, etc.

[0554] 7. Select perception nodes based on existing technologies and configure perception measurements for the perception nodes.

[0555] 8. The perception node (UE or RAN) can send the perception data to SF-C / SF-U through the control plane or through the user plane. The SF directly opens the processed perception results to AF / AS, or opens them to AF / AS through NEF / local NEF (Local NEF, L-NEF), or sends the perception results to UE through AMF.

[0556] Example 2:

[0557] This example introduces the AF / AS / UE / NF triggered perception process. AMF discovers suitable SF-C and SF-U based on the perception request, and sends the perception data processing rules to SF-U through SF-C to realize the collection, processing and exposure of perception data. Among them, SF-U is type 2.

[0558] Fig.11 The example 2 network element interaction diagram provided in the embodiment of the present application is as follows: Fig.11 As shown, the main process includes:

[0559] 1. AF / AS / UE initiates a perception request. AMF receives the perception request, which carries the service type, service requirements (perception resolution, perception accuracy, frame rate, duration, target area information, latency, perceived target information), etc.

[0560] 2. AMF obtains SF-C (and SF-U) registration information from NRF.

[0561] 3. AMF selects SF-C according to the target area information or target UE location information, and the service area, sensing capability (such as sensing accuracy), QoS requirement (such as sensing delay), load, sensing time, etc. of SF-C. Optionally, AMF selects SF-U according to DNAI and S-NSSAI, load, target area information or target UE location information, service area, sensing capability (such as sensing accuracy), QoS requirement (such as sensing delay), load, sensing time, etc. of SF-U.

[0562] 4a. AMF sends a perception request to SF-C. The perception request includes information of SF-U, such as the identifier and IP address of SF-U. The perception request also includes perception requirements, such as perception accuracy, perception resolution, frame rate, perception time, target area information, QoS requirements (e.g., latency), and perceived target information.

[0563] 4b. (Optionally) AMF sends a sensing request to SF-U, which includes information of SF-C, such as the identifier and IP address of SF-C. The sensing request also includes data collection requirements, such as the type of sensing data, data accuracy, data collection time, and data provision time.

[0564] 5. (Optionally) If the AMF does not select an SF-U in step 3, the SF-C selects an SF-U based on DNAI, S-NSSAI, load, target area information or target UE location information, service area of ​​the SF-U, sensing capability (e.g., sensing accuracy), QoS requirements (e.g., sensing latency), load, sensing time, etc. The SF-C may obtain the information of the SF-U by requesting the NRF or through local configuration information.

[0565] 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 generating intermediate data or generating 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).

[0566] 7. Select perception nodes based on existing technologies and configure perception measurements for the perception nodes.

[0567] 8. The perception node (UE or RAN) can send the perception data to SF-C / SF-U through the control plane or the user plane. SF-U sends the collected perception data to SF-C. SF-C analyzes and processes the perception data to obtain the perception results and then opens them to AF / AS, or opens them to AF / AS through NEF / L-NEF, or sends the perception results to UE through AMF.

[0568] Example 3:

[0569] 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 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, 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 aggregation node SF-U for aggregation and processing; 2) SF-U processes to generate the final data (perception result) and directly opens it to AF / AS / UE / NF; 3) SF-U directly sends the received original perception data to the aggregation node SF-U for aggregation and processing. 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 aggregation node SF-U can be type one, and other SF-Us can be type two, and so on. In this example, all type one SF-Us can also be replaced with SF.

[0570] Fig.12 The example 3 network element interaction diagram provided in the embodiment of the present application is as follows: Fig.12 As shown, the main process includes:

[0571] 1. The sensing node (RAN or UE) sends the sensing data to the SF-U to which it is connected.

[0572] 2. After SF-U receives the sensed data, it processes the data based on the sensed data processing rules configured by SF-C in the following ways:

[0573] 1) If the sink node indication is included or the sink node indication is set to TRUE, or if the sink node address information is not included, it is determined as the sink node. Receive the original perception data / intermediate data (e.g., point cloud data) / final data sent by other SF-Us and perception nodes, perform corresponding processing, and open the final integrated perception results to the target receiving end AF / AS / UE / NF, such as Fig.12 Follow step 2b in the previous step.

[0574] 2) If it does not contain the sink node indication or the sink node indication is set to FALSE, or contains the sink node address information, it is determined that it does not serve as a sink node. Receive the original sensing data / intermediate data / final data sent by other SF-Us and sensing nodes, process them accordingly to generate intermediate data / final data and send them to the sink node, such as Fig.12 Or the SF-U processes and generates the final data (perception result) and directly opens it to the target receiving end AF / AS / UE / NF, such as Fig.12 Follow step 2c in the previous step.

[0575] If it is type 2 SF-U, the collected perception data needs to be sent to SF-C first, and SF-C will analyze and process the perception data to obtain the perception results and then open them to AF / AS / UE / NF.

[0576] Example 4:

[0577] This example describes that when a SF-U reports changes in its communication / perception capabilities to AMF / SF-C (for example, excessive load, changes in the perception area resulting in failure to meet perception requirements, etc.), it triggers AMF / SF-C to reselect SF-U. Alternatively, SF-C determines that SF-C itself needs to be changed or SF-U needs to be changed, and sends an indication message to AMF. AMF determines that SF-C and / or SF-U need to be reselected based on SF-C's indication or AMF based on UE location information, etc. In this example, SF-U can also be replaced by SF, and there is no SF-C subscription.

[0578] Fig.13 The example 4 network element interaction diagram provided in the embodiment of the present application is as follows: Fig.13 As shown, the main process includes:

[0579] 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 source SF-U). The subscription request information may include thresholds corresponding to parameters such as load and perception area. When this threshold is exceeded, SF-U sends notification information.

[0580] 1b. (Optionally) SF-C determines that SF-C itself needs to be changed or SF-U needs to be changed, and sends an indication message to AMF.

[0581] 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 communication / perception requirements, such as load, area, etc.

[0582] AMF / SF-C reselects SF-U (the SF-U may be referred to as target SF-U) according to DNAI, S-NSSAI, load, target area information or target UE location information.

[0583] 2b. (Optionally) AMF, based on the indication of SF-C (if 1b is performed), or AMF determines that SF-U needs to be reselected (for example, based on the UE moving to a new location and having moved out of the service area of ​​the original SF-U), reselects SF-C and / or SF-U according to DNAI, S-NSSAI, load, target area information or target UE location information.

[0584] The subsequent steps are the same as steps 5-9 of Example 1.

[0585] Example 5:

[0586] This example describes how to register SF-C and SF-U with NRF, and how to discover SF-U and SF-C through NRF.

[0587] Example 5a: Register with NRF.

[0588] Method 1: SF-C and SF-U register with NRF separately.

[0589] 1) SF-U sends a registration request message to NRF, which includes one or more of the following: service area, perception capability (perception mode, supported perception data reporting mode, perception delay, perception accuracy, IP address and / or port number information, etc.), supported DNAI(s), S-NSSAI, type of collectible data, data collection delay, and data accuracy.

[0590] 2) SF-C sends a registration request message to NRF, the message includes: one or more of the registration service area and sensing capability (sensing method, etc.).

[0591] The service areas registered by SF-U and SF-C may be different.

[0592] Method 2: SF-C locally configures SF-U information, and SF-C registers its own information with NRF, and optionally registers SF-U information.

[0593] Example 5b: Discovering SF-U through NRF.

[0594] When NF (such as AMF, SF-C) needs to select SF-U, it obtains the information of SF-U by interacting with NRF. Fig.14 The example 5b network element interaction diagram provided in the embodiment of the present application is as follows: Fig.14 As shown, the main process includes:

[0595] 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.

[0596] 2. NRF sends a first network element discovery response message (Nnrf_NFDiscoveryResponse) to NF, which includes one or more of the SF-U identifier, IP address, and port number.

[0597] Example 5c: Discovery of SF-C by NRF.

[0598] When NF (such as AMF) needs to select SF-C, it obtains SF-C information by interacting with NRF. Its process is similar to that of discovering SF-U, mainly including:

[0599] 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.

[0600] 2. NRF sends a second network element discovery response message (Nnrf_NFDiscoveryResponse) to NF, which includes one or more of the SF-C identifier, IP address, and port number.
