[0033] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] It should be noted that the terms "first", "second", and the like in the description and claims of the present disclosure and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence.

[0035] The method embodiments provided in the embodiments of the present disclosure can be executed in a computer device or similar computing device. Taking a computer device as an example, Fig. 1 is a hardware structure block diagram of a computer device running a communication-aware service processing method according to an embodiment of the present disclosure. As shown in Fig. 1, the computer device can include one or more (only one is shown in Fig. 1) processors 102 (the processor 102 can include but is not limited to a processing device such as a microprocessor MCU or programmable logic device) and a memory 104 for storing data, wherein the above computer device can further include a transmission device 106 for communication function and an input and output device 108. Those skilled in the art can understand that the structure shown in Fig. 1 is only schematic, which does not limit the structure of the above computer device. For example, the computer device can include more or less components than those shown in Fig. 1, or have a different configuration from that shown in Fig. 1.

[0036] The memory 104 can be used to store computer programs, for example, software programs of application software and modules, such as the computer program corresponding to the communication-aware service processing method in the embodiments of the present disclosure. The processor 102 executes various functions and applications and single board matching by running the computer program stored in the memory 104, that is, implements the above method. The memory 104 can include a high-speed random access memory, and can also include a non-volatile memory, such as one or more magnetic storage devices, flash memories, or other non-volatile solid-state memories. In some examples, the memory 104 can further include a memory remotely arranged with respect to the processor 102, which can be connected to the computer device through a network. Examples of the above network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.

[0037] The transmission device 106 is used to receive or send data via a network. Specific examples of the above network can include a wireless network provided by a communication provider of the computer device. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC for short), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (Radio Frequency, RF for short) module, which is used to communicate with the Internet in a wireless manner.

[0038] With the rapidly growing demand of diversified applications, more and more requirements are put forward for wireless communication networks, which promotes the continuous enhancement of wireless network capabilities. While communication network devices meet more stringent communication service performance, they will also expand to support more application service capabilities, among which, sensing is one of the most potential development capabilities. Communication sensing fusion not only provides the required basic environment sensing and target object sensing capabilities for building intelligent services and intelligent networks, but also promotes the innovation of new application services. Therefore, communication sensing fusion is one of the important research technical directions in the current industry.

[0039] The sensing capability of the wireless access network or terminal is only a prerequisite for the communication network to provide sensing requirements. How to provide sensing services according to the sensing business requirements by using the communication network is a problem that needs to be solved at present.

[0040] The embodiment of the disclosure provides a communication system based on a communication sensing business processing method, which can provide end-to-end communication sensing business. FIG. 2 is a communication system architecture diagram based on a communication sensing business processing method according to an embodiment of the disclosure, as shown in FIG. 2, the communication system includes a sensing network element (sensing function, SF) and a sensing device.

[0041] Among them, the sensing network element is used to send a sensing control request message to the sensing device, receive sensing data from the sensing device, and send a sensing result of the sensing business to the first network element based on the sensing data; the sensing network element receives a sensing business request message sent by the first network element, and the sensing business request message is used to request a sensing business; the sensing network element sets the sensing control request message according to the sensing business request message and sends it to the sensing device.

[0042] The sensing device is used to receive sensing configuration parameters and a sensing control request message from the sensing network element, execute a sensing operation according to the sensing control request message, obtain sensing data, and send the sensing data to the sensing network element.

[0043] Further, the communication system further includes a first network element. Among them, the first network element can be one of the following network elements: a network capability exposure function network element, an access and mobility management function network element, an application function network element, an application server AS or a terminal device.

[0044] The first network element sends a sensing business request message to the sensing network element, and the sensing business request message is used to request a sensing business, wherein the first network element is a core network element, an external application server AS / AF (application server / application function) or a terminal user equipment UE; the first network element is a sensing requester;

[0045] In this embodiment, the request message carries awareness indication information, where the awareness indication information is used to indicate a request for awareness service.

[0046] In this embodiment, the request message carries a service type of the first awareness service. This implementation mode can assist the first awareness network element in obtaining the requirements of the awareness service based on the service type.

[0047] Specifically, the service type includes one or more of the following: object distribution, map, driving, violation detection, object trajectory tracking, emergency detection, object positioning, object contour size, object speed, weather prediction, human posture, and human health.

[0048] In different awareness fusion scenarios, the feedback requirements of the awareness result by the awareness service requester are also different. For example, in the weather monitoring and railway inspection scenarios, the awareness result needs to be fed back periodically; for example, in the flight intrusion detection and home security detection scenarios, the awareness result needs to be fed back when an event occurs; for example, in the high-precision map and path planning scenarios, the awareness result needs to be fed back continuously and uninterruptedly. If the awareness service requester only wants to know the current information (position, surrounding environment, speed, etc.) of a UE, the awareness result needs to be fed back immediately. That is, it includes single feedback, periodic feedback, and event-triggered feedback.

[0049] In this embodiment, the request message carries an awareness requester identifier and / or an awareness application identifier of the awareness service. The awareness requester is also sometimes referred to as the demander of the awareness service (or awareness service) herein.

[0050] In an implementation form of any of the above aspects, the awareness control request message includes awareness control information, where the awareness control information is used to control the terminal to perform an awareness operation indicated by the awareness control information. The awareness control information includes a service type of the awareness service.

[0051] In this embodiment, the awareness control request message carries awareness indication information, where the awareness indication information is used to instruct the UE to perform an awareness operation.

[0052] The awareness service requirements can be divided into multiple levels, mainly including the following parameters: awareness service type, resolution and accuracy of distance / speed / angle of the awareness target, refresh rate, target detection rate, target false alarm rate, awareness area, detection speed interval, duration, feedback period, and time delay.

[0053] The awareness control function will generate awareness control parameters based on awareness service requirements, network awareness capability, network topology, awareness service policy, etc., mainly including the following parameters: distance / speed / angle resolution and accuracy, frame rate, duration, awareness measurement data reporting period, update or end process instruction, etc.

[0054] In the embodiment, the sensing network element can meet the demand of the sensing service of the first network element, bring another dimension of service capability for the mobile network element, and improve the network performance.

[0055] The network needs to support sensing function, and the network element containing main sensing function (i.e. sensing control function and sensing calculation function) is called SF (Sensing Function) in the research report. The sensing network element SF can be an independent network element, or can be combined with other network elements, and the deployment mode can be centralized or distributed. The NRF (Network Repository Function) stores the context information of the sensing network element, so that other network elements can discover and select the appropriate sensing network element by querying.

[0056] Among them, the specific functions contained in the sensing network element include:

[0057] How to perform sensing QoS (Quality of Service) parameter conversion: in order to meet the QoS demand of sensing service, QoS parameter conversion needs to be performed. The sensing service type or identifier, QoS requirement and sensing measurement data reporting period and other information are transmitted to the terminal or base station performing sensing. If the sensing demand changes, such as the sensing area, data reporting time or QoS requirement changes, the terminal or application needs to trigger the corresponding modification process;

[0058] The terminal can perform sensing operation to obtain sensing measurement data as a sensing device, but each terminal has corresponding sensing permission, including the PLMN network that can perform sensing, the sensing mode that can be selected, whether it can be a discovery UE or a cooperative UE, whether it can calculate the sensing result or report the sensing measurement data to the network to calculate the sensing result, which wireless sensing resources can be used, and which security and privacy policies need to be followed. The terminal needs to obtain these sensing configuration parameters before performing sensing, so that the UE can legally, regularly, efficiently and accurately perform sensing detection. The configuration parameters include parameters in the network coverage and parameters in the case of no network coverage.

[0059] The embodiments of the present disclosure can be applied to a long term evolution (LTE) system, a long term evolution-advanced (LTE-A) system, an enhanced long term evolution-advanced (eLTE), a 5th generation (5G) mobile communication system New Radio (NR) system, 5G-A (5G-Advanced) mobile communication system, a 6th generation (6G) mobile communication system, and can also be extended to similar wireless communication systems, such as wireless-fidelity (WiFi), worldwide interoperability for microwave access (WIMAX), and a 3rd generation partnership project (3gpp) related cellular system.

[0060] FIG. 3 is a 5G sensing system architecture diagram according to an embodiment of the present disclosure, as shown in FIG. 3, the functions of the terminal device and each network entity are as follows.

[0061] Sensing network element: a core network sensing control and sensing measurement data processing network element, including processing of sensing measurement data of 3GPP sensing devices, and processing of sensing measurement data of non-3GPP sensing devices; specifically, the specific functions of the SF include at least one of the following:

[0062] (1) Sensing Quality of Service (QoS) parameter conversion: to meet the QoS requirements of sensing services, QoS parameter conversion is required. The sensing service type or identifier, QoS requirements, and sensing measurement data reporting period information are transmitted to the terminal or base station performing sensing. If the sensing requirements change, such as changes in sensing area, data reporting time, or QoS requirements, the terminal or application needs to trigger the corresponding modification process;

[0063] (2) Triggering of sensing services;

[0064] (3) Termination of sensing services;

[0065] (4) Control of base stations or terminals to perform sensing according to sensing service requirements;

[0066] (5) Efficient processing of sensing measurement data;

[0067] (6) Providing / opening of sensing results.

[0068] The perception network element obtains the perception demand based on the demand of the network internal demand or the demand of the demand side of the perception service. After the perception network element obtains the perception demand, the terminal device is controlled to perform the detection and / or collection of the perception data. After the user equipment obtains the perception data through detection, the perception data is provided to the perception network element, and the perception service is provided based on the perception data by the perception network element. Exemplarily, the perception network element provides the perception service to the demand side, for example, to the AF, the external application server or the terminal device, and the like. Alternatively, the core network optimizes the network internal based on the perception data, and the like.

[0069] Terminal device: also can be called user equipment (UE), access terminal, subscriber unit (SU), terminal device station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, terminal device agent or terminal device apparatus.

[0070] Wireless access network: a network composed of multiple RAN nodes, which implements the functions of wireless physical layer, resource scheduling and wireless resource management, wireless access control and mobility management. The RAN is connected through the user plane interface N3 and the UPF, which is used to transmit the data of the terminal device; the RAN establishes a control plane signaling connection through the control plane interface N2 and the AMF, which is used to realize the functions of wireless access bearer control and the like.

[0071] The 5G sensing system architecture of the embodiments of the present disclosure adds a perception sub-function, i.e., a perception control plane function (SF-C) and a perception user plane function (SF-U), which sets interfaces and interacts with the 5GC network elements such as the Advanced Message Queuing Protocol (AMF), Network Element Function (NEF), Unified Data Management (UDM), Network Data Analytics Function (NWDAF), Policy Control Function (PCF) and User Plane Function (UPF), as shown in FIG. 3. The perception control signaling between the perception control plane function and the RAN / UE is transmitted through the AMF, and the perception measurement data obtained by the UE can be transmitted to the perception user plane network element through the user plane, which can be forwarded through the UPF or directly transmitted to the SF.

[0072] In addition, the 5G sensing system architecture also adds UE B connected with UE A through the PC5 interface. UE A can discover UE B through the Sidelink to jointly perform the sensing task. The inter-UE sensing task and data interaction can be carried on the PC5 interface. Similarly, UE A and UE B interact through the PC5 interface.

[0073] In addition, the two SF network elements newly added in the 5G sensing system architecture can independently deploy 5GC network elements (such as AMF or Location Management Function (LMF)) and / or collocate deployment according to the sensing requirements,

[0074] Among them, the basic functions include:

[0075] Sensing control plane function (SF-C, SF Control Plane Function): interacts with the existing 5GC control plane network element, is responsible for control plane message transmission, and provides the address of the sensing user plane function to the base station / UE;

[0076] Sensing user plane function (SF-U, SF User Plane Function): responsible for collecting and analyzing the sensing measurement data generated by the terminal or base station, obtaining the final sensing result, and opening it to the UE or application. The application can be AF or Data Network (DN); wherein the sensing measurement data can be forwarded through the UPF or directly transmitted to the sensing user plane function. In addition, the sensing user plane function also needs to support the sensing billing when the UE or (R)AN performs sensing.

[0077] The sensing control plane function interacts with the 5GC control plane network element, and the sensing user plane function interacts with the base station or UPF. The specific interface definition is as follows:

[0078] NS1: a new NS1 interface between the sensing control plane function and the AMF. This interface can transmit sensing control signaling; for the scenario of transmitting sensing measurement data on the control plane, this interface can also transmit sensing measurement data;

[0079] NS2: a new NS2 interface between the sensing control plane function and the NEF. This interface can transmit signaling messages exchanged between the sensing network element and the business side AF through the NEF, and also open the sensing result to the AF;

[0080] NS3: a new NS3 interface between the sensing control plane function and the UDM. Through this interface, authentication or authorization can be realized, and UE sensing subscription information, service AMF information, or other information can be obtained;

[0081] NS4: a new NS4 interface between the perception control plane function and the NWDAF, through which the perception control plane function can jointly complete AI processing related to the perception service with the NWDAF;

[0082] NS5: a new NS5 interface between the perception control plane function and the PCF, through which the perception control plane function can deliver information such as perception requirements or QoS requirements or perception results of the perception service to the PCF, and the PCF generates PCC policies related to the perception service based on the decision;

[0083] NS6: a new NS6 interface between the perception network element and the LMF, through which the perception network element can obtain location-related information such as a perception area, RAN information of a perception target, and location information of a perceived UE;

[0084] NS7: a new NS7 interface between the perception user plane function and the UPF, through which the perception measurement data can be directly transmitted from the (R)AN to the perception network element through the user plane function, or indirectly forwarded to the perception network element through the UPF. In the scenario where the (R)AN performs perception through the UPF, the UPF needs to be modified to support (R)AN-granularity data transmission;

[0085] NS8: a new NS8 interface between the perception control plane function and the perception user plane function, through which the perception processing strategy and the perception result can be delivered.

[0086] In addition to the above new interfaces, existing interfaces (such as N1, N2, N5, N8, N33, etc.) need to support the delivery of information related to the perception service, such as authentication information, perception service type, perception service quality requirement, perception measurement data, and perception result.

[0087] The above network elements or functions can be network elements in a hardware device, or virtualized functions instantiated on a dedicated hardware.

[0088] The software function, or a virtualized function instantiated on a platform (for example, a cloud platform). For example, the above network elements or functions can be implemented by one device, or by multiple devices together, or can be a functional module in a device, and the present disclosure does not specifically limit this.

[0089] The access network device in the present embodiment can be a wireless access network device.

[0090] In addition, the above "network element" can also be referred to as an entity, a device, an apparatus, or a module, etc., and the present disclosure does not specifically limit it.

[0091] Also, for the convenience of understanding and description, the description of "network element" is omitted in the following part of the description, for example, the NEF network element is referred to as NEF, in this case, "NEF" should be understood as the NEF network element or the NEF entity, and the description of the same or similar cases is omitted below.

[0092] It should be understood that FIG. 3 is only an exemplary system architecture, and the network architecture applicable to the embodiments of the present disclosure is not limited thereto, and any network architecture capable of realizing the functions of the above-mentioned network elements is applicable to the embodiments of the present disclosure.

[0093] For example, in some network architectures, network function entities such as AMF, Service Management Function (SMF), PCF, and UDM are all referred to as network function (NF) network elements; or in other network architectures, the set of network elements such as AMF, SMF, PCF, and UDM can be referred to as control plane function (CPF) network elements.

[0094] Next, the specific scheme details are introduced by taking the network elements in the 5G system as an example. It can be understood that when the scheme is used in the LTE system or future communication systems, each network element in the scheme can be replaced by other network elements with corresponding functions, and the present disclosure does not limit this.

[0095] In the present embodiment, a communication-aware service processing method running on the above computer device is provided, and FIG. 4 is a flowchart I of the communication-aware service processing method according to an embodiment of the present disclosure, as shown in FIG. 4, applied to a sensing device, the flow includes the following steps:

[0096] Step S402, receiving a sensing control request message sent by a sensing network element, the sensing control request message being used to request the sensing device to perform a sensing operation;

[0097] Step S404, performing the sensing operation according to the sensing configuration parameter and the sensing control request message, to obtain sensing data of the sensing service;

[0098] Step S406, sending the sensing data to the sensing network element, the sensing data being used to instruct the sensing network element to provide a sensing result of the sensing service to a sensing requestor.

[0099] Through the above steps S402 to S406, the problem of how to provide sensing services according to the sensing service requirements by using the communication network in the related art can be solved, and the communication-aware service can be provided.

[0100] In one embodiment, before step S402, before receiving the sensing control request message sent by the sensing network element, the method further comprises: sending sensing capability indication information. Further, the sending of the sensing capability indication information can be to one of: the access network device, the sensing requestor.

[0101] In one embodiment, performing sensing operation according to the sensing configuration parameter and the sensing control request message to obtain sensing data of the sensing service comprises: sending a wireless signal to a preset area, a preset location or a preset object, and receiving a return signal; and obtaining the sensing data based on the return signal.

[0102] In this embodiment, the sensing device comprises: a base station or a terminal, and the sensing configuration parameter should be configured to the sensing device before the terminal performs sensing, so that the sensing device can perform sensing detection legally, in compliance with regulations, efficiently and accurately. Moreover, the sensing configuration parameter needs to be considered not only for use in the case of network coverage, but also for use in the case of no network coverage. Specifically, the sensing configuration parameter is configured through PC5 and / or Uu interface based on one of the following manners:

[0103] Preconfigured in the ME;

[0104] Configured in the UICC;

[0105] Preconfigured in the ME and configured in the UICC;

[0106] Provided or updated by the sensing application server;

[0107] Provided or updated by the core network (for example, PCF).

[0108] Further, if the same configuration parameter described above is provided by different sources, the UE should consider the following priority:

[0109] (1) Provided / updated by the core network;

[0110] (2) Provided / updated by the sensing application server through V1 reference point;

[0111] (3) Configured in the UICC;

[0112] (4) Preconfigured in the ME.

[0113] In an embodiment, the sensing device is exemplified by a UE. The sensing device UE performs a sensing operation, and generally configures dedicated wireless resources for sensing. If the sensing operation and air interface communication use shared resources, the air interface resources at a certain time point can need to be limited to prevent resource conflicts. For a periodic sensing operation, the UE performs the sensing operation according to a preconfigured sensing interval parameter, or the UE requests a sensing interval from a network base station, the base station configures the sensing interval for the UE, and the UE performs the sensing operation using the interval. For a periodic, single-time or event-triggered sensing operation, if the UE performs sensing and communication operations at the same time and frequency, the UE compares the priority of the sensing service and a preconfigured priority threshold. If the priority of the sensing service is lower than the preconfigured threshold (the lower the priority value, the higher the priority), the UE prioritizes the sensing operation, otherwise, the UE performs the communication operation. If the UE performs sensing and communication operations at the same time and different frequencies, the UE compares the priority of the sensing service and a preconfigured priority threshold. If the priority of the sensing service is lower than the preconfigured threshold (the lower the priority value, the higher the priority), the UE prioritizes the sensing operation or reduces the communication power, otherwise, the UE prioritizes the communication operation or reduces the sensing power. If the network does not configure the sensing interval and the priority threshold, the communication has a higher priority, i.e., the communication operation is performed first, and then the sensing operation is performed.

[0114] The sensing device sends a wireless signal to a specific area, a specific location or a specific object, and receives a return signal; and / or, based on the return signal, obtains sensing data.

[0115] In this embodiment, the terminal performs a sensing operation according to the sensing configuration parameter and the sensing configuration message, and obtains sensing data; the sensing network element receives the sensing data from the terminal, and provides a sensing service to a sensing requester based on the sensing data, which can form an end-to-end service with the sensing capability.

[0116] In this embodiment, the sensing scenario can be divided into a Per-Area sensing scenario and a Per-Object sensing scenario according to whether the sensing requirement is mainly for a specified sensing area or a specified sensing target. The sensing technology uses a wireless signal to sense a target or a state of the surrounding environment. The terminal or the base station on the wireless side collects information such as signal strength, time delay, phase change, Doppler frequency shift, and outputs the result after calculation and processing, such as target size, position, speed, etc. In this process, the network needs to trigger, modify or end the sensing process according to the service requirement, schedule wireless resources, process data, and open the result. In addition, since the sensing can involve user privacy and security, the core network needs to perform authentication or authorization, and process sensitive sensing measurement data. Therefore, the network needs to support control of the sensing process, process the sensing measurement data, and open the sensing result to a third-party platform or terminal.

[0117] The perception operation can represent the following meanings:

Further, when the perception feedback method is periodic feedback, the perception control information also includes a feedback cycle.

[0122] Figure 5 is a flowchart of the communication sensing service processing method according to an embodiment of the present disclosure. As shown in Figure 5, it includes the following steps:

[0123] S501, the sensing device (UE) obtains sensing configuration parameters.

[0124] The perception configuration parameters are used by the UE to perform perception operations, including: the PLMN network that can perform perception, the selectable perception methods, whether it can act as a discovering UE or a cooperating UE, whether the UE can calculate the perception results or the UE can report perception measurement data and have the network calculate the perception results, which radio perception resources are available, and which security and privacy policies must be followed, etc.

[0125] S502, the first network element sends a sensing service request message to the sensing network element.

[0126] S503, the sensing network element sends a sensing control request message to the UE.

[0127] Among them, the perception control request message is used to request the UE to perform perception operations.

[0128] S504, the UE performs a perception operation and obtains perception data based on the perception control request message and perception configuration parameters.

[0129] For example, the request message carries the perception requester identifier and / or perception application identifier of the perception service.

[0130] The sensing requester identifier indicates the requester of the sensing service. The sensing application identifier indicates the application (APP) requesting the sensing service, and is used by the NEF, AMF, or sensing network element to determine whether the sensing requester and / or the sensing application is allowed to request the first sensing service.

[0131] Sensing data includes one of the following: raw signals, basic measurement data, or sensing results;

[0132] S505, the UE sends sensing data to the sensing network element. The sensing network element receives the sensing data from the UE.

[0133] S506, the sensing network element provides sensing services based on sensing data.

[0134] In step S506, the sensing network element can provide sensing services to the sensing requester, i.e., the demander of the sensing service (hereinafter referred to as the demander), based on the request. The demander can be, for example, a core network element or a non-core network element, such as an external application server (AS), or the demander can also be a terminal device. The demander can be understood as the first network element in the following text.

[0135] In one embodiment, a sensing network element receives a request message from a first network element, which requests sensing services. After receiving the request message, the sensing network element sends sensing results to the first network element based on the sensing data.

[0136] In one embodiment, the core network element can be a Network Capability Opening Function (NEF), an Access and Mobility Management Function (AMF), or an Application Function (AF). For example, in New Radio (NR), the NEF can be the Network Capability Opening Function, the AMF can be the Access and Mobility Management Function, and the AF can be the Application Function.

[0137] In one embodiment, a sensing network element receives a request message from a first network element, and the sensing network element sends a response message to the first network element, the response message carrying the sensing result.

[0138] In one embodiment, a sensing network element receives a request message from a first network element. The sensing network element then sends a response message to the first network element, which does not carry sensing result data; the response message serves only as an acknowledgment, indicating that the sensing network element has accepted the request from the first network element. The sensing network element subsequently sends sensing result data to the first network element through other messages.

[0139] In one embodiment, a sensing network element receives a request message from a first network element, the request message being used to request a sensing service. When the feedback method of the sensing data for this sensing service is event-triggered feedback, based on the event trigger, the sensing network element obtains the sensing data for the sensing service from the UE and sends the sensing result data to the first network element. Alternatively, after obtaining the sensing data for the sensing service from the UE, the sensing network element determines that an event has been triggered based on the sensing data, and then sends the sensing result data to the first network element.

[0140] In one embodiment, the request message received by the sensing network element from the first network element carries sensing indication information, which is used to indicate the request for sensing services.

[0141] In one embodiment, performing a sensing operation based on sensing configuration parameters and the sensing control request message includes:

[0142] For periodic sensing operations, the sensing operation is performed according to a pre-configured sensing interval parameter, or the sensing operation is performed using a requested sensing interval;

[0143] For periodic sensing operations, single-event or event-triggered sensing operations, if sensing and communication operations are performed at the same time and frequency, if the sensing service priority value is less than the pre-configured priority threshold, the sensing operation is executed first; if the sensing service priority value is greater than the pre-configured priority threshold, the communication operation is executed first. If sensing and communication operations are performed at the same time but different frequencies, if the sensing service priority value is less than the pre-configured priority threshold, the sensing operation is executed first or the communication power is reduced; if the sensing service priority value is greater than the pre-configured priority threshold, the communication operation is executed first or the sensing power is reduced. If the network has not configured sensing intervals and priority thresholds, the communication operation is executed first, followed by the sensing operation.

[0144] In one embodiment, in step S402 above, receiving the sensing control request message sent by the sensing network element includes: receiving the sensing control request message sent by the sensing network element according to the sensing service request message of the sensing requester; and / or presetting the sensing configuration parameters, or receiving the sensing configuration parameters through the core network element or application server.

[0145] In one embodiment, in step S404 above, performing a sensing operation to obtain sensing data for a sensing service based on the sensing configuration parameters and the sensing control request message includes: determining at least one of the following based on the sensing configuration parameters: the PLMN network performing the sensing, the sensing method, whether it is a cooperative sensing device, the sensing data processing method, wireless sensing resources, and a security and privacy policy; performing the sensing operation to obtain sensing data; wherein the sensing configuration parameters include at least one of the following: the PLMN network performing the sensing, the sensing method, whether it is a cooperative sensing device, whether the sensing result is calculated by the sensing device or the sensing data is reported by the sensing device and the sensing result is calculated by the network, wireless sensing resources, and a security and privacy policy. Further, the sensing method includes one of the following: base station transmits and UE receives, UE transmits and base station receives, UE transmits and receives independently, UE A transmits and UE B receives.

[0146] The sensing nodes in the mobile communication network of this disclosure include sensing network elements, sensing devices (including base stations and terminals), and other network elements enhanced to support network sensing capabilities (such as AMF). Sensing requirements include sensing of target geographical locations or target objects. Therefore, the network needs to select appropriate sensing nodes for the sensing task. Selecting a sensing node requires considering its location, capabilities, load, and authentication or authorization information. Since sensing services may involve privacy, the network first needs to perform authentication or authorization upon receiving a sensing request. Terminals, internal network elements, or applications trigger the sensing process, transmitting the sensing requirement to the sensing network element. The sensing network element can operate independently or interact with other network elements to complete authentication or authorization, sensing network element selection, and sensing device selection.

[0147] When a sensing service is initiated, the sensing network element (SF) first needs to determine the sensing method to use based on the type of sensing service, the information of the sensing service requester, and the sensing requirement information, including:

[0148] Base station A transmits and base station B receives, or base station A transmits and UE receives, or base station A transmits and receives itself, or UE transmits and UE receives, or UE A transmits and UE B receives, etc. In this disclosure, the sensing device is UE, which includes: base station transmitting and UE receiving, or UE transmitting and receiving itself, or UE A transmitting and UE B receiving;

[0149] Secondly, the sensing network element selects suitable sensing equipment to serve the sensing service based on the decided sensing method and sensing equipment capabilities, thereby transmitting sensing signals, measuring sensing signals, and reporting sensing measurement data. In particular, for indoor sensing scenarios, the base station may be deployed outdoors of the sensing target, or there may be obstacles such as walls blocking the view, with no LOS path between the base station, the UE, and the sensing target. In this scenario, using signals between the RAN and the UE, or signals between RANs, to sense the target may be ineffective.

[0150] If multiple UEs are present indoors where the target is located, a UE-to-UE sensing method (A transmits, B receives) can be used for measurement to achieve better sensing results. Besides the Uu interface, sensing terminals can also be discovered via the PC5 interface. One possible scenario is that the network assigns a sensing task to a UE A, which discovers other nearby UEs B as sensing nodes through a sidelink, jointly completing the sensing task. This method can provide richer sensing measurement data sources for indoor scenarios with limited network signal LOS paths, optimizing the efficiency and results of sensing task execution.

[0151] The transmission path and protocol for sensing measurement data, and whether it can be transmitted via the control plane or user plane, need to be determined based on an analysis of the impact on the existing network, considering factors such as the data volume and upload cycle, to select an appropriate transmission method. Specifically, the sensing measurement data transmitted from the UE to the SF is divided into several layers, including raw signals, basic measurement data, and sensing results.

[0152] (1) If the original signal is transmitted, the data transmission volume is too large and needs to be transmitted through the user plane;

[0153] (2) If the data being transmitted is basic measurement data, the data transmission volume is large and needs to be transmitted via the user plane.

[0154] (3) If the data transmitted is a sensing result, the data transmission volume is small and can be transmitted via the control plane or the user plane.

[0155] Perception results: These are data related to business functions and performance obtained through further calculation and analysis of perceived measurement data. Examples include the presence of a target, the target's distance, speed, orientation, acceleration, position, trajectory, movement, facial expression, respiratory / heart rate, imaging results, weather, air quality, material and composition, etc.

[0156] The sensing network element SF determines or obtains appropriate sensing service quality policy information from PCF (Policy Control Function) for sensing services, which is used to indicate the sensing resource policy and sensing execution policy allocated by the communication network for the sensing service.

[0157] Sensing services involve the interaction of sensing control information and the transmission of sensing measurement data. If different sensing services have different requirements for sensing-related data transmission, the network (such as SF or PCF) also needs to formulate differentiated communication transmission service quality policy information for sensing services to indicate the communication transmission resources and transmission strategies allocated by the communication network for the sensing service.

[0158] Depending on the sensing scenario and business requirements, the sensing signals received by the sensing device may need to be processed by one or more processing nodes, such as the UE, the base station, or NWDAF (Network Data Analytics Function), or SF, or the sensing server, in order to obtain the final sensing measurement data or sensing results.

[0159] When a business is initiated, the following is required:

[0160] It supports providing sensing measurement data directly to the sensing requester, or processing the sensing measurement data before providing it to the sensing requester.

[0161] Supports the selection of appropriate sensing measurement data processing nodes;

[0162] It supports processing sensing measurement data according to sensing requests and outputting corresponding content or data formats.

[0163] In different sensor fusion scenarios, the feedback requirements of the sensing service requester for sensing results vary. For example, weather monitoring and railway inspection scenarios require periodic feedback of sensing results; flight intrusion detection and home security detection scenarios require feedback when a certain event is detected; and high-precision map and route planning scenarios require continuous and uninterrupted feedback of sensing results. If the sensing service requester only wants to know the current information of a UE (location, surrounding environment, speed, etc.), then immediate feedback of sensing results is required.

[0164] For different business scenarios, the triggering party, the executor, and the granularity of perception vary, and the network architecture needs to support perception services in multiple scenarios. In a wireless network, base stations or terminals obtain corresponding perception measurement data by transmitting wireless signals to target areas or objects and measuring the received wireless signals. Perception network elements need to be able to independently or jointly process perception measurement data (i.e., the values ​​of perception measurement data reported by base stations or terminals) to generate perception results. Data processing needs to consider single-base station perception, multi-base station perception, single-UE perception, multi-UE perception, as well as scenarios involving UE identification and cross-base station movement. Perception network elements can process perception measurement data independently or jointly with NWDAF (Network Data Analytics Function) to achieve intelligent analysis and prediction. The processing of perception measurement data needs to consider multiple scenarios. In multi-base station perception, the perception areas of different base stations may overlap, requiring data segmentation and extraction; when UEs participate in perception, a UE identification scheme needs to be defined; when UEs move across base stations, data of the same target needs to be processed together.

[0165] This embodiment provides a communication sensing service processing method running on the aforementioned computer device. Figure 6 is a flowchart of the communication sensing service processing method according to an embodiment of this disclosure. As shown in Figure 6, the method is applied to a sensing network element and includes the following steps:

[0166] Step S602: Send a perception control request message to the perception device. The perception control request message is used to request the perception device to obtain the perception data of the perception service according to the perception configuration parameters and the perception control request message.

[0167] Step S604: Receive sensing data sent by the sensing device;

[0168] Step S606: Provide the perception results of the perception service to the perception requester based on the perception data.

[0169] Through the above steps S602 to S606, the problem of how to provide sensing services using a communication network according to the sensing service requirements in related technologies can be solved, and communication sensing services can be provided.

[0170] In one embodiment, in step S602 above, sending a sensing control request message to the sensing device includes: receiving a sensing service request message sent by the sensing requester, wherein the sensing service request message is used to request the sensing service; and sending the sensing control request message according to the sensing service request message.

[0171] In this embodiment, the sensing service request message carries the service type, service identifier, or service indication information of the sensing service. Further, the sensing service request message also carries the service requirements of the sensing service, wherein the service requirements include at least one of the following: a first sensing distance, a first sensing area, a first sensing speed range, a first sensing distance resolution, a first sensing angle measurement accuracy, a first sensing speed resolution, a first sensing QoS requirement, a first sensing location point, a first sensing UE identifier, first sensing time information, a first sensing object recognition accuracy, a first sensing object recognition false alarm rate, a first sensing data accuracy, a first sensing data update frequency, a first sensing dimension indication, and a first sensing feedback method.

[0172] In this embodiment, for clarity and conciseness, the set of information described above will be referred to as the first information set. Perception range resolution refers to the minimum distance at which two targets can be distinguished when they are located at the same azimuth angle but at different distances from the sensing network element. In other words, perception range resolution defines the ability of a sensing network element to distinguish two near-range targets.

[0173] Perceptual angular accuracy refers to the ability of a sensing element to distinguish neighboring targets by angle, and is usually measured by the smallest resolvable angle. Alternatively, angular accuracy can also be called angular resolution.

[0174] Sensing velocity resolution refers to the ability of a sensing element to distinguish targets in terms of radial velocity. Alternatively, sensing velocity resolution can be defined as the sensing velocity accuracy range or the sensing velocity error range.

[0175] The perceived location point can be either an absolute or relative geographical coordinate, without limitation.

[0176] The UE identifier can be an external identifier of the UE, such as the generic public subscription identifier (GPSI).

[0177] In one embodiment, the object recognition accuracy can refer to the probability of judging a target as existing when the target actually exists.

[0178] For example, if the probability of judging a target as having a target when it actually exists is P, then the probability of judging a target as not having a target when it actually exists is 1-P.

[0179] The first object recognition accuracy can be the recognition accuracy obtained by using at least one of the following to perceive and recognize the target object: perception distance resolution, perception angle measurement accuracy, and perception velocity resolution.

[0180] The false alarm rate of first-sensory object recognition can refer to the probability of judging a target as present when it does not actually exist, or it can refer to the probability of judging a target as absent when it actually exists.

[0181] For example, if the probability of judging a target as having a target when it does not actually exist is Q, then the probability of judging a target as not having a target when it does not actually exist is 1-Q.

[0182] It should be noted that object recognition accuracy and object recognition false alarm rate are two different parameters.

[0183] The false alarm rate of object recognition can be obtained by using at least one of the following to perceive and recognize the target object: perception distance resolution, perception angle measurement accuracy, and perception velocity resolution.

[0184] Alternatively, object recognition accuracy or false alarm rate can be replaced by the recognition of scattering points of the target object. That is, the recognition success rate and false alarm rate are obtained by recognizing the target object based on at least one of the sensing distance resolution, sensing angle accuracy, and sensing velocity resolution.

[0185] In one embodiment, the precision of the perceived data can be the image resolution.

[0186] In one embodiment, the perceived data update frequency can be the image frame rate.

[0187] Additionally, it is important to distinguish between the perceived data update frequency and the perceived data feedback cycle. For example, a perceived dimension indicator is used to indicate the dimensions of the perceived data.

[0188] For example, the first perceptual dimension indicates whether the perceptual data is two-dimensional planar data or three-dimensional solid data.

[0189] The first perceived time information includes the duration of time, or the start and end times, etc.

[0190] Furthermore, the first sensory feedback method can be one or more of the following:

[0191] One-time feedback, periodic feedback, and event-triggered feedback.

[0192] When the first sensing feedback method is periodic feedback, the business requirements of the first sensing service also include the first feedback cycle of the first sensing data. This cycle can be one or more.

[0193] In one embodiment, the business requirements for sensing services include one or more of the following information:

[0196] First sensing distance, first sensing area, first sensing speed range, first sensing distance resolution, first sensing angle measurement accuracy, first sensing speed resolution, first sensing object recognition accuracy, first sensing object recognition false alarm rate, first sensing data accuracy, and first sensing data update frequency.

[0197] The sensing network element sends a sensing control request message to the UE. In one implementation, the sensing control request message includes sensing control information, which is used to control the sensing device to perform the sensing operation indicated by the sensing control information.

[0198] In this embodiment, the perception control request message includes perception control information, wherein the perception control information is used to instruct the perception device to perform the perception operation to obtain the perception data. Further, the perception control information includes at least one of the following: a second perception distance, a second perception area, a second perception speed range, a second perception distance resolution, a second perception angle measurement accuracy, a second perception speed resolution, a second perception QoS requirement, a second perception location point, a second perception UE identifier, second perception time information, a second perception object recognition accuracy, a second perception object recognition false alarm rate, a second perception data accuracy, a second perception data update frequency, a second perception dimension indication, a perception detection cycle, and a second perception feedback method.

[0199] The second perception feedback method includes at least one of the following: single feedback, periodic feedback, and event-triggered feedback.

[0200] For clarity and conciseness, the set of information described above will be referred to as the second information set below. Here, the perception detection cycle is used to indicate the cycle in which the second sensing network element performs perception detection (or perception operation), or the cycle in which the UE performs perception.

[0201] In one embodiment, the sensing detection period can be obtained based on the update frequency of the second sensing data.

[0202] Furthermore, when the second sensing feedback method is periodic feedback, the sensing control information also includes the period in the second feedback.

[0203] Furthermore, the second sensed QoS requirement includes one or more of the following:

[0204] Second service priority, second data rate, and second latency.

[0205] Data rate refers to the rate at which a business is perceived.

[0206] In this embodiment of the disclosure, the first delay or the second delay refers to the delay from when the demander of the sensing service requests the sensing service to when it obtains the sensing service.

[0207] Alternatively, the first or second delay refers to the delay from when the sensing device performs sensing and detection until the demand side obtains the sensing result from the sensing network element.

[0208] Alternatively, the first or second delay refers to the delay between the sensing device obtaining the sensing data and the demand side obtaining the sensing result from the sensing network element.

[0209] In one embodiment, the sensing control information includes one or more of the following: second sensing QoS requirements, second sensing location point, second sensing UE identifier, second sensing time information, second sensing dimension indication, sensing detection period, and second sensing feedback method.

[0210] The second sense QoS requirement includes one or more of the following:

[0211] Second sensing distance, second sensing area, second sensing speed range, second sensing distance resolution, second sensing angle measurement accuracy, second sensing speed resolution, second sensing object recognition accuracy, second sensing object recognition false alarm rate, second sensing data accuracy, and second sensing data update frequency.

[0212] In one embodiment, the sensing network element obtains sensing control information based on the service type and / or service requirements.

[0213] The sensing network element can receive request messages from the first network element, which carry the service type and / or service requirements of the requested first sensing service. Service requirements may include one or more of the information sets mentioned above.

[0214] A sensing network element can determine one or more pieces of information in a second information set based on one or more pieces of information in a first information set. In other words, the first sensing network element determines one or more pieces of information in the second information set based on one or more pieces of information in the first information set, and thus determines the information carried in the control request message.

[0215] In one embodiment, the sensing network element obtains sensing control information by performing one or more of the following operations: obtaining a second sensing distance based on a first sensing distance;

[0216] The second sensing region is obtained based on the first sensing region;

[0217] Obtain the second sensing location point based on the first sensing location point;

[0222] It should be understood that one or more of the aforementioned first sensing distance, first sensing area, first sensing location point, first sensing UE identifier, first sensing time information, first sensing feedback method, and first feedback period may be included in the request message from the first network element.

[0223] In one embodiment, the first-aware UE identifier is an external identifier (e.g., GPSI), which the first-aware network element converts into an internal identifier, such as a subscription permanent identifier (SUPI) or a globally unique temporary identity (GUTI), a system architecture evolution-temporary mobile subscriber identity (S-TMSI), a next-generation application protocol identifier (NGAP ID), or a cell-radio temporary identity (C-RNTI), or other internal UE IDs that can be recognized by the first-aware network element.

[0224] The sensing network element also performs one or more of the following operations:

[0225] Based on the first perceived QoS requirement, obtain the second perceived QoS requirement; or,

[0226] Based on the service type of the first sensing service, the second sensing QoS requirements are obtained.

[0233] Second sensing distance resolution, second sensing angle measurement accuracy, second sensing velocity resolution, second sensing object recognition accuracy, and second sensing object recognition false alarm rate.

[0234] In one embodiment, the perception control information may include: a region perception indication; or, a region perception indication and a second region.

[0235] In one embodiment, the sensing control information may include a region sensing indication, which may implicitly instruct the RAN to sense its coverage area without explicitly indicating a sensing region.

[0236] In one embodiment, the sensing control information may include a region sensing indication and a second region, wherein the region sensing indication is used to instruct the RAN to perform a sensing operation on the second region.

[0237] In one embodiment, the perception control information may include: a UE perception indication and a second perception UE identifier; or, a UE perception indication and UE location information; or, a UE perception indication, a second perception UE identifier, and UE location information.

[0238] The UE perception indication indicates that the perception operation is for a UE, and the perception control information may carry the identifier of the UE to be perceived (i.e., the second perceived UE identifier). For example, the perception control information may include the UE perception indication and UE location information, indicating that the second perception network element perceives the current location of the UE.

[0239] In one embodiment, the perception control information may include a UE perception indication, the identifier of the UE to be perceived, and the UE's location information.

[0240] In one embodiment, if the perception control information includes a continuous tracking instruction and a second perception area, then the second perception network element is instructed to continuously track all targets within the second perception area.

[0241] In one embodiment, the perceived control information includes the service type.

[0242] In one embodiment, the sensing data may be one of the following data obtained by the UE based on the echo signal: time-domain digital signal, range-velocity spectrum information, location information and velocity value of the scattering point, and location information and velocity value of the target object.

[0243] In one embodiment, the first sensing data can be acquired in one of the following ways:

[0244] The UE acquires the first sensing data based on the echo signal;

[0245] The UE first acquires a time-domain digital signal based on the echo signal, and then acquires sensing data based on the time-domain digital signal; or, the UE first acquires range-velocity spectrum information based on the echo signal, and then acquires sensing data based on the range-velocity spectrum information; or...

[0246] The UE first obtains the location and velocity information of the scattering point based on the echo signal, and then obtains sensing data based on the location and velocity information of the scattering point; or,

[0247] The UE first obtains the position information and velocity value of the target object based on the echo signal, and then obtains the sensing data based on the position information and velocity value of the target object.

[0248] In one embodiment, in step S606 above, providing the perception result of the perception service to the perception requester based on the perception data includes: when the feedback method of the perception data is event-triggered feedback, sending the perception result to the perception requester after receiving the perception data from the perception device based on the event trigger; or sending the perception result to the perception requester after receiving the perception data from the perception device based on the event trigger.

[0249] In one embodiment, in step S606 above, providing the perception result of the perception service to the perception requester based on the perception data includes: sending a perception control response message to the perception requester, wherein the perception control response message carries the perception result; or sending the perception result to the perception requester through other messages.

[0250] In one embodiment, Figure 7 is a schematic diagram of the AF-triggered sensing process according to an embodiment of the present disclosure. As shown in Figure 7, the sensing request can be triggered by an AF application or an internal network element. The AF sends the sensing request directly to the SF node through the NEF or internal network element, or through the AMF to the SF node, thereby enabling the SF to control the base station or UE to perform sensing measurements according to the sensing request, and to calculate based on the sensing measurement data reported by the base station or UE and release the sensing results to the AF or return them to the internal network element. The main steps include:

[0251] S701, the perception application AF sends a fusion perception service request information to NEF, carrying the service type (such as dynamic map, vehicle speed detection, vehicle tracking, emergency event notification, vehicle audit), service requirements (perception resolution, perception accuracy, frame rate, duration, target area information, latency, perception target information (such as vehicle type, vehicle identification, location information)), and specified perception node information (such as UE information), etc.

[0252] In S702, the NEF performs authorization checks on the AF's service awareness requests. Authorization information can be stored locally in the NEF or UDM. The NEF can request authorization verification from the UDM. The NEF obtains privacy check information from the UDM and performs privacy checks. For example, if the UE does not allow a certain type of service to obtain perception measurement data or perception results related to itself, the NEF rejects the perception request. The NEF routes the perception request based on its parameters. From the UE user's perspective, perception measurement data or perception results include environmental information surrounding the UE, which is a relatively private type of data. Borrowing the privacy check approach from LCS (Location Service), if an application wants to obtain perception measurement data or perception results around the UE, the network needs to first confirm whether the UE user allows the application to obtain such data.

[0253] For the architecture where SF and LMF are co-located, GMLC needs to be introduced between NEF and AMF. NEF sends the perception request from AF to GMLC, and GMLC and UDM perform the above authorization check. GMLC then feeds back the result to AMF.

[0254] S703. After NEF authorization is approved, NEF selects a suitable AMF and sends a service awareness request message to the AMF, i.e., steps S703-S705 are executed. When an internal network element triggers, the internal network element selects a suitable AMF and sends a service awareness request message to the AMF.

[0255] If it is a region-oriented perception, NEF selects the AMF that serves the region based on the region information in the AF request.

[0256] If it is target-oriented perception, the NEF selects the AMF serving the area based on the target location information in the AF request; if the target itself has a UE communication module and has UE capabilities, such as a vehicle, then target-oriented perception can be considered as perceiving the area around the UE. In this case, the AMF serving the UE can be selected as the AMF, and the NEF obtains the AMF information serving the UE by querying the UDM.

[0257] In this embodiment, NEF can first select SF, and then SF selects AMF. When an internal network element triggers, the internal network element selects SF, and then SF selects AMF.

[0258] If it is a region-oriented perception, NEF selects the SF that serves the region based on the region information in the AF request.

[0259] If it is target-oriented perception, NEF selects the SF serving the area based on the target location information in the AF request; if the target itself has a UE communication module and has UE capabilities, such as a vehicle, then target-oriented perception can be considered as perceiving the surroundings of the UE. In this case, the SF serving the UE can be selected as the SF, and NEF obtains the AMF ID serving the UE by querying UDM, and then selects the appropriate SF based on the AMF ID.

[0260] In S704, for an architecture where SF and LMF are co-located, the GMLC performs the above operations. That is, after authorization, the GMLC selects a suitable AMF and sends a perception service request message to the AMF. For area-aware scenarios, the GMLC can also directly select an LMF without going through the AMF and send a perception request to the LMF; therefore, the GMLC needs to support LMF selection functionality. The AMF selects a suitable SF based on target area information or target location information. The SF can register its service area with the NRF, allowing the AMF to select an SF by querying the NRF.

[0261] S705, AMF sends the perception request to SF.

[0262] S706, if SF selects to use the RAN-based sensing method according to the sensing request, then execute S706a (see Figure 9);

[0263] If the SF selects to use the UE-assisted sensing method based on the sensing request, then S706b is executed (see Figure 10);

[0264] If the SF selects to use the UE-based perception method based on the perception request, then S706c is executed (see Figure 11).

[0265] If the base station and terminal are able to perform the sensing operation, they return a sensing response to the SF, carrying a success indication; otherwise, they carry a failure indication.

[0266] The sensing network element then returns a sensing response to the third-party application that requested the service.

[0267] S707, SF performs sensing calculations based on the sensing measurement data fed back by the base station and obtains the final sensing result.

[0268] S708, the SF returns the perception results to the AMF. For area perception scenarios, the SF can return the results to the AF via the AMF and NEF, or directly return the perception results to the AF via the NEF. For an architecture where the SF and LMF are co-located, the AMF returns the perception results to the AF via the GMLC and NEF.

[0269] In S709, the AMF returns the sensing results to the AF via the NEF. For an architecture where the SF and LMF are co-located, the AMF returns the sensing results to the AF via the GMLC and NEF. When an internal network element triggers a connection, the AMF sends the sensing results to that internal network element.

[0270] Figure 8 is a schematic diagram of the UE-triggered sensing process according to an embodiment of the present disclosure. As shown in Figure 8, the process begins with the UE triggering a sensing request. The AMF then directly sends the sensing request to the SF node, thereby enabling the SF to control the base station or UE to perform sensing measurements based on the sensing measurement data reported by the base station or UE and return the sensing results to the UE. The UE requesting the sensing service in Figure 8 may be the same as or different from the UE performing the sensing service. Specifically, the process includes the following steps:

[0271] S801, the UE initiates a perception request to the AMF, carrying the service type (such as dynamic map, vehicle speed detection, vehicle tracking, emergency event notification), service requirements (perception resolution, perception accuracy, frame rate, duration, target area information, latency, perception target information (such as vehicle type, vehicle identification, location information)), and specified perception node information (such as UE information).

[0272] In S802, the AMF selects a suitable SF based on the target area information or the target UE location information. The SF can register its service area with the NRF, allowing the AMF to select the SF by querying the NRF. When the LMF and SF are co-located, the AMF selects the LMF(SF) and sends a sensing request to the LMF(SF).

[0273] S803, AMF sends the perception request to SF.

[0274] S804, if SF selects to use the RAN-based sensing method according to the sensing request, then execute S804a (see Figure 9);

[0275] If SF selects to use UE-assisted sensing mode based on the sensing request, then S804b is executed (see Figure 10);

[0276] If the SF selects to use the UE-based perception method based on the perception request, then S804c is executed (see Figure 11).

[0277] If the base station and terminal are able to perform the sensing operation, they return a sensing response to the SF, carrying a success indication; otherwise, they carry a failure indication.

[0278] The sensing network element then returns a sensing response to the UE requesting the service.

[0279] In an architecture where SF and LMF are co-located, the LMF (SF) can reuse the NRPPa procedure to obtain measurement data from the RAN node, and can reuse the LPP procedure to obtain measurement data from the UE. Related messages can be transmitted via the control plane or the user plane.

[0280] S805, SF performs sensing calculations based on the sensing measurement data fed back by the base station and obtains the final sensing result.

[0281] S806, SF returns the perception results to AMF.

[0282] S807, AMF returns the perception results to UE.

[0283] Figure 9 is a schematic diagram of the RAN sensing process according to an embodiment of the present disclosure. As shown in Figure 9, when the sensing mode is base station self-transmission and self-reception, or base station A transmits and B receives, the SF sends a sensing control request to the RAN to control the RAN to initiate the detection and acquisition of sensing measurement data. Specifically, it includes the following steps:

[0284] S901: The SF selects a suitable RAN based on the target area information / target object location information and sends a sensing control request to the RAN to control the RAN to perform sensing detection; it also carries the IP address and port number of the SF-U for receiving sensing measurement data. For a loosely coupled architecture, the SF can send the data directly to the base station without going through the AMF.

[0285] S902, RAN detects and acquires sensing measurement data.

[0286] In S903, the RAN reports the sensing measurement data to the SF-U. For a tightly coupled architecture, the base station can send the data to the SF through the AMF or UPF; for a loosely coupled architecture, the base station can send the data directly to the SF without going through the AMF or UPF.

[0287] S904, SF-U reports to SF-C that it has received sensing measurement data. In an architecture where SF and LMF are co-located, LMF(SF) acquires the measurement data and calculates the sensing results. LMF(SF) can reuse the NRPPa process to acquire sensing measurement data from the RAN node, and related messages (e.g., sensing measurement data) can be transmitted via the control plane or the user plane.

[0288] Figure 10 is a flowchart illustrating the UE-assisted sensing process according to an embodiment of the present disclosure. As shown in Figure 10, when the sensing mode is UE transmitting and base station receiving, or base station transmitting and UE receiving, the SF sends a sensing control request to the RAN and UE to control the RAN and UE to initiate the detection and acquisition of sensing measurement data, specifically including the following steps:

[0289] S1001, the SF selects a suitable RAN based on the target area information / target object location information, or the SF first selects a suitable AMF, and the AMF then selects a suitable UE based on the target area information / target object location information, and sends a perception control request to the RAN and UE to control the RAN and UE to perform perception detection; at the same time, it carries the IP address and port number of the SF-U for receiving perception measurement data from the RAN or UE. For loosely coupled architectures, the SF can send the data directly to the base station without going through the AMF.

[0290] In an architecture where SF and LMF are co-located, the LMF obtains relevant sensing measurement data from the RAN node or the UE, and calculates the sensing results based on the sensing measurement data. The LMF can reuse the NRPPa procedure when obtaining measurement data from the RAN node, and can reuse the LPP procedure when obtaining measurement data from the UE. Related messages can be transmitted via the control plane or the user plane.

[0291] In S1002, the RAN and UE probe for sensing measurement data and acquire this data. The RAN can interact with the UE to collect basic information, including sensing capability information, sensing resource requirements, and allocated sensing resource information.

[0292] S1003, the RAN or UE reports the sensing measurement data to the SF-U. For a tightly coupled architecture, the base station can send the data to the SF through the AMF or UPF; for a loosely coupled architecture, the base station can send the data directly to the SF without going through the AMF or UPF.

[0293] S1004, SF-U reports to SF-C that it has received sensing measurement data.

[0294] Figure 11 is a schematic diagram of the UE sensing process according to an embodiment of the present disclosure. As shown in Figure 11, the sensing mode can be UE self-transmission and self-reception, or when UE-A transmits and UE-B receives, the SF sends a sensing control request to the UE according to the request information to control the UE to initiate the detection and acquisition of sensing measurement data. Specifically, it includes the following steps:

[0295] S1101, the SF selects a suitable UE based on the target area information / target object location information, or the SF first selects a suitable AMF, and the AMF then selects a suitable UE based on the target area information / target object location information, and sends a perception control request to the UE to control the UE to perform perception detection; at the same time, it carries the IP and port number of the SF-U for receiving perception measurement data from the UE.

[0296] In the co-located SF and LMF architecture, the LMF obtains relevant perception measurement data from the UE and calculates the perception results based on the perception measurement data. The LMF can reuse the LPP procedure to obtain measurement data from the UE. Related messages can be transmitted via the control plane or the user plane.

[0297] S1102, the UE detects and acquires sensing measurement data.

[0298] S1103, the UE reports the sensing measurement data to the SF-U.

[0299] S1104, SF-U reports to SF-C that it has received sensing measurement data.

[0300] Figure 12 is a flowchart illustrating a sensing service without network participation according to an embodiment of this disclosure. As shown in Figure 12, the sensing service scenarios without network participation include scenarios where UE1 transmits and receives data independently, and scenarios where UE1 transmits and UE2 receives data. Before a UE performs a local sensing service (without network participation), the network needs to pre-deploy the sensing service-related policies and configuration parameters to the UE. When using operator resources, additional operator authorization is also required. For multiple UEs to collaboratively perform sensing services, the roles of sensing transmitter and sensing receiver need to be determined first. Specifically, the following steps are included:

[0301] S1201a, in the UE self-transmitting and self-receiving mode, UE1 initiates sensing services according to the corresponding local policies and configurations.

[0302] In S1201b, under the mode of UE1 transmitting and UE2 receiving, it is necessary to discover the sensed service. The discovery mechanism of near-field communication can be reused. This needs to include information on sensed capabilities, such as sensed transmission capability or sensed reception capability, in order to determine the sensed reception or transmission role of UE1 and UE2.

[0303] S1202 After determining the above roles, UE1 and UE2 will proceed with the establishment of awareness services, which requires interaction service-related parameters, QoS parameters, etc.

[0304] S1203, Sensing measurement data acquisition and processing: Depending on the business needs, the sensing measurement data can be processed by UE1 or UE2. For example, if UE1 acts as the sensing receiver, the sensing measurement data can be processed by UE1; conversely, if UE2 acts as the sensing receiver, it can process the sensing measurement data.

[0305] S1204, As needed for business operations, the processing results of perception measurement data (i.e., perception reports) can be exchanged between UE1 and UE2. For example, when UE2 processes perception measurement data, it can send the perception report to UE1.

[0306] Figure 13 is a schematic flowchart of UE perception parameter configuration according to an embodiment of this disclosure. As shown in Figure 13, the perception parameter configuration process is used by the 5G network to provide the terminal device with the configuration parameters necessary for performing perception operations. Core network elements (such as PCF) can act as the controller of perception configuration parameters, responsible for parameter storage, push, update, and cancellation operations. When the UE determines that it lacks perception parameters or the current perception parameters are invalid, the UE triggers a perception parameter configuration process to request the corresponding parameters from the PCF: the perception parameter validity timer has expired; there are no relevant parameters, for example: no parameters for the perception service that the UE wants to use, no parameters for the area where the UE is currently located, or the parameters are lost due to abnormal conditions. Specifically, it includes the following steps:

[0307] S1301, the UE sends UE perception capability information and UE policy message to the AMF via NAS message. The UE policy message includes a perception parameter configuration request message.

[0308] S1302, the AMF selects a PCF that supports the perception capability based on the UE's perception capability information.

[0309] S1303, the AMF sends a UE policy message (perception parameter configuration request message) to the selected PCF.

[0310] S1304, PCF determines the corresponding perception configuration parameters for UE.

[0311] S1306, the PCF sends the perception configuration parameters to the UE as part of the UE policy via the AMF.

[0312] S1307, the UE stores the aware configuration parameters and returns a response message to the PCF.

[0313] When the perception application (AF) needs to send its application-related perception configuration parameters to the UE, the AF triggers a perception parameter configuration process to the PCF.

[0314] Figure 14 is a flowchart illustrating the configuration of AF trigger sensing parameters according to an embodiment of the present disclosure. As shown in Figure 14, the specific steps include:

[0315] S1401, AF sends a UE perception parameter configuration request message to NEF.

[0316] S1402, after NEF authorizes the AF request, it stores the AF request in the UDR.

[0317] S1403, PCF obtains AF request from UDR:

[0318] For a registered UE, the UDR sends a notification message to the UE's PCF;

[0319] For unregistered UEs, the PCF of the UE will request AF from the UDR after the UE registers with the network.

[0320] S1404, PCF determines the corresponding perception configuration parameters for UE based on AF request.

[0321] S1405, the PCF sends the perception configuration parameters to the UE as part of the UE policy via the AMF.

[0322] S1406, the UE stores the aware configuration parameters and returns a response message to the PCF.

[0323] Figure 15 is a schematic diagram of the Sidelink discovery selection process for the auxiliary UE according to an embodiment of the present disclosure. As shown in Figure 15, when the sensing mode is UE-A transmits and UE-B receives, the SF can send a Sidelink UE auxiliary sensing request to the target UE. The target UE discovers the auxiliary UE via Sidelink through Model A or Model B according to the received request. After the auxiliary UE establishes a connection with the current SF, the current SF can perform sensing by controlling the target UE and the auxiliary UE, specifically including the following steps:

[0324] S1501, the SF selects a suitable UE based on the target area information / target object location information, and determines that the perception needs to be performed using the UE-1 transmit and UE-2 receive method according to the perception task. It sends a Sidelink UE assisted perception request to the UE to control the UE to discover the assisted UE through the Sidelink method; at the same time, it carries the ID information of SF-C or the IP and port number of SF-U for the assisted UE to establish a connection with the SF.

[0325] S1502a, the UE sends a notification message to the surrounding area, which includes information related to the sensing task, such as the required sensing capabilities, as well as the ID information of the SF-C or the IP and port number of the SF-U, for establishing a connection with the SF.

[0326] S1502b, the surrounding auxiliary UEs receive the announcement message, determine that they have the capability to support the sensing task and are willing to complete the sensing task as auxiliary UEs, and establish a connection with the SF using the SF information contained in the announcement message.

[0327] S1503a, the UE listens for solicitation messages sent by surrounding UEs. Surrounding auxiliary UEs send discovery solicitation messages to the UE, which carry their awareness capability information.

[0328] S1503b, the UE determines that the auxiliary UE can complete the perception task and sends a discovery response message to the auxiliary UE, which contains the ID information of SF-C or the IP and port number of SF-U.

[0329] S1503c, assists the UE in establishing a connection with the SF using the SF information contained in the discovery response message.

[0330] The UE may discover the auxiliary UE through Model A or Model B. If Model A is used, steps 2a and 2b are executed. If Model B is used, steps 3a-3c are executed.

[0331] S1504, SF determines the UE and auxiliary UEs to perform the task based on information from the UE and multiple optional auxiliary UEs, and determines the allocation of their sender and receiver.

[0332] S1505, SF controls the UE and assists the UE in performing perception measurements.
