[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on October 30, 2023, with application number 202311426503.0 and invention name “A communication method and communication device for perception”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and more particularly, to a communication method and a communication device for sensing. Background Art

[0003] In the evolution from fifth-generation (5G) mobile communication systems to 5G-Advanced (5G-A) technology, integrated communication and perception technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. This technology aims to integrate wireless communication and perception functions into a single system, leveraging the various propagation characteristics of wireless signals to build the ability to detect and image targets. This allows communication and perception capabilities to coexist harmoniously within a single network, achieving even mutual benefit.

[0004] In a perception scenario, multiple perception entities may be involved. These entities can collect data within their respective perception service coverage areas, thereby collaborating to complete the perception service. Considering the mobility of the perception target, when the perception target moves, it may move out of the perception service range of the current perception entity and enter an area that cannot be perceived, resulting in the inability to continuously perform the perception service.

[0005] Therefore, there is an urgent need for a communication method for sensing that can ensure the continuity of wireless sensing services when the sensing target moves.

[0006] Summary of the Invention

[0007] The present application provides a communication method and a communication device for perception, which can ensure the continuity of wireless perception services when the perception target moves.

[0008] In a first aspect, a communication method for sensing is provided. The method can be performed by a first sensing entity or a first network device, or by a chip or circuit configured in the first sensing entity or the first network device, or by a logic module or software capable of implementing all or part of the functions of the first sensing entity or the first network device. This application is not limited to this.

[0009] The method includes: receiving first configuration information, the first configuration information includes a first threshold, the first threshold is used to indicate the perception range of the first perception entity for the first perception service, the first threshold is determined based on the service requirements of the first perception service, and the first perception service is implemented based on the first perception entity's perception of the first perception target; determining another perception entity to execute the first perception service based on the first configuration information and the location information of the first perception target.

[0010] In the present application, the method can be applied to the first perception entity or the first network device.

[0011] Among them, the first perception entity is an access network device or terminal device with perception function, which is not limited in this application.

[0012] The first network device is a network entity with a perception data processing function, such as SDPF.

[0013] In a perception scenario, when the perception target moves within the maximum perception service range of the perception entity, the perception entity can determine valid perception data based on the perception signal. However, for the perception needs of different perception services, even if the perception target moves within the maximum perception service range, the continuity of the perception target's perception service may not be guaranteed, and the current perception service may be interrupted or have other failures. This application proposes to determine another perception entity to perform the current perception service based on the perception range of the business needs of the perception service, wherein the stability of the service can be ensured when the perception target moves within the perception range based on the business needs of the perception service, and another perception entity can be determined based on the perception range to perform the current perception service, thereby ensuring the continuity of the perception service. In other words, the perception entity not only needs to be able to meet the maximum perception service range, but also needs to meet the perception range of the business needs of the current perception service. This ensures the continuous upload of effective perception data for the perception service, meets the needs of the perception service, and improves the perception capability.

[0014] In combination with the first aspect, in certain implementations of the first aspect, determining that another perception entity performs the first perception service is based on the first configuration information and the location information of the perception target, including: determining a first distance, where the first distance is the distance between the first perception target and the first perception entity; when the first distance is greater than or equal to a first threshold, determining that another perception entity performs the first perception service.

[0015] In this technical solution, when it is determined that the current position of the first perception target has exceeded the perception range of the perception needs for the first perception service, another perception entity can be determined to perform the first perception service. That is, when the first perception target moves out of the perception range of the first perception entity for the business needs of the first perception service, the first perception service may be interrupted. At this time, it is necessary to determine another perception entity to perform the first perception service to ensure the continuity of the first perception service.

[0016] In combination with the first aspect, in certain implementations of the first aspect, first request information is generated based on the first configuration information, and the first request information is used to request the second perception entity to perform the first perception service; the first request information is sent to the second perception entity.

[0017] In this technical solution, the first perception entity or the first network device can determine another perception entity (second perception entity) based on the first configuration information, and request the second perception entity to perform the first perception service through the first request information.

[0018] In combination with the first aspect, in some implementations of the first aspect, the first request information includes indication information of the first perception service, indication information of the first perception entity, indication information of the second perception entity, and perception information.

[0019] In this application, the indication information of the first perception service, for example, can be the identifier or name of the first perception service, or other information indicating the first perception service, which is not limited in this application; the indication information of the first perception entity, for example, can be the identifier or name of the first perception entity, or other information indicating the first perception entity, which is not limited in this application; the indication information of the second perception entity, for example, can be the identifier or name of the second perception entity, or other information indicating the second perception entity, which is not limited in this application. This will not be repeated in the following text.

[0020] In this application, the perception information may include location information, point cloud information, etc. of the first perception target.

[0021] In combination with the first aspect, in certain implementations of the first aspect, when the method is applied to a first perception entity, the first configuration information also includes indication information of the perception entity and a first discrimination mode, the indication information of the perception entity includes indication information of the first perception entity and indication information of perception entities adjacent to the first perception entity, and the first discrimination mode is used to instruct the first perception entity to determine the second perception entity.

[0022] It can be understood that the first discrimination mode instructs the first sensing entity to determine another sensing entity to perform the first sensing service. The first sensing entity can determine the other sensing entity based on the sensing capability information and location information of the adjacent sensing entities.

[0023] In combination with the first aspect, in some implementations of the first aspect, the first configuration information may further include the maximum effective perception distance of the second perception entity and other adjacent perception entities and location information of the second perception entity and other adjacent perception entities.

[0024] In combination with the first aspect, in some implementations of the first aspect, the first perception entity receives a second request message from the second perception entity or the first network device; and stops executing the first perception service according to the second request message.

[0025] In this application, the first sensing target is in a mobile state. When the first sensing target has entered the sensing range of the second sensing entity for the business needs of the first sensing service, the first sensing entity can stop sensing. In this case, the first sensing entity can determine that the first sensing target has entered the sensing range of the second sensing entity for the business needs of the first sensing service based on the second sensing entity or the first network device, and thus stop executing the first sensing service. This solution can not only ensure the continuity of the sensing service, but also further save the power consumption of the first sensing entity.

[0028] In combination with the first aspect, in certain implementations of the first aspect, the first configuration information may also include the maximum effective perception distances of the first perception entity, the second perception entity, and other adjacent perception entities, and location information of the second perception entity and other adjacent perception entities.

[0029] In combination with the first aspect, in some implementations of the first aspect, the first network device sends second request information to the first perception entity, where the second request information is used to request to stop executing the first perception service.

[0030] In combination with the first aspect, in some implementations of the first aspect, the first configuration information further includes a second threshold value, and the second threshold value is used to indicate the perception range of the second perception entity for the service demand of the first perception service.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the first network device or the second perception device determines a second distance, where the second distance is the distance between the first perception target and the second perception entity; when the second distance is less than or equal to a second threshold, a second request information is sent to the first perception entity.

[0032] In this scheme, the second perception entity can determine by itself that the first perception target has entered the perception range of the second perception entity for the business needs of the first perception service, or the first network device can determine based on the perception data that the first perception target has entered the perception range of the second perception entity for the business needs of the first perception service, thereby instructing the second perception entity to stop perception.

[0035] In the present application, when the first perception entity or the first network device determines another perception entity, it may also request the second network device to determine the second perception entity.

[0036] It can be understood that the second network device has a control function. The second network device obtains the perception capability information and location information of the first perception entity and the adjacent perception entity through the registration stage. Therefore, the second network device can determine the appropriate perception entity based on the perception range of each perception entity for the business needs of the first perception service.

[0037] Exemplarily, the second network device may obtain the maximum effective sensing distances of the second sensing entity and other adjacent sensing entities and location information of the second sensing entity and other adjacent sensing entities.

[0041] In combination with the first aspect, in some implementations of the first aspect, the first perception entity receives sixth request information from the second network device; and stops executing the first perception service according to the sixth request information.

[0042] In this application, the first sensing target is in a mobile state. When the first sensing target has entered the sensing range of the second sensing entity for the service demand of the first sensing service, the first sensing entity can stop sensing. In this case, the first sensing entity can determine that the first sensing target has entered the sensing range of the second sensing entity for the service demand of the first sensing service based on the second network device, and thus stop executing the first sensing service. This solution can not only ensure the continuity of the sensing service, but also further save the power consumption of the first sensing entity.

The third request information is determined based on the sensing scope of the service requirements of the first sensing service. That is, the first sensing entity may not meet the sensing scope of the service requirements of the current sensing service. The second network device determines that the second sensing entity performs the first sensing service, thereby ensuring the continuous upload of effective sensing data for the sensing service, meeting the requirements of the sensing service, and improving sensing capabilities.

[0117] First, a brief introduction to the network architecture applicable to the embodiments of the present application is given as follows.

[0118] FIG1 is a schematic diagram of a wireless communication system 100 applicable to an embodiment of the present application. As shown in FIG1 , the wireless communication system 100 may include at least one network device, such as the network device 110 shown in FIG1 . The wireless communication system 100 may also include at least one terminal device, such as the terminal device 120 and the terminal device 130 shown in FIG1 . Both the network device and the terminal device may be configured with multiple antennas, and the network device and the terminal device may communicate using multi-antenna technology. Terminal devices may also communicate with each other. For example, terminal devices may communicate directly with each other. For another example, terminal devices may communicate with each other through other communication devices, such as network devices or other terminal devices.

[0119] When a network device communicates with a terminal device, the network device can manage one or more cells, and a cell can have an integer number of terminal devices. Optionally, network device 110 and terminal device 120 form a single-cell communication system. Without loss of generality, this cell is referred to as cell #1. Network device 110 can be a network device in cell #1, or network device 110 can serve a terminal device (e.g., terminal device 120) in cell #1.

[0120] It should be noted that a cell can be understood as an area within the coverage range of wireless signals of network equipment.

[0121] It should be understood that Figure 1 is a simplified schematic diagram for ease of understanding, and the wireless communication system 100 may also include other network devices or other terminal devices, which are not shown in Figure 1. The embodiments of the present application can be applied to any communication scenario in which a transmitting device and a receiving device communicate.

[0122] To facilitate understanding of the embodiments of the present application, the following is a brief explanation of the terms involved in the embodiments of the present application.

[0123] 1. Integrated sensing and communication (ISAC):

[0124] In the field of communications, communication and perception can be integrated, allowing a communication system to simultaneously perform both functions. This allows for both information transmission over wireless channels and the ability to perceive the physical characteristics of the surrounding environment by actively learning and analyzing channel characteristics, thereby enhancing the communication and perception functions. In communication-integrated perception technology, a sensing device can transmit a perception signal and receive a signal (also known as an echo signal) reflected from a perceived target to determine the target's attributes. For example, this information can include the target's speed, distance, shape, size, and other information. The perceived target can be a fixed object such as a mountain, forest, or building, or a movable object such as a vehicle, drone, pedestrian, or terminal device. A sensing device can also be referred to as a sensing device, a detector, or a communication device with perception capabilities (such as a terminal device or access network device). Perception capabilities can include at least the ability to transmit a perception signal and receive an echo signal.

[0125] 2. Self-perception:

[0126] In this application, self-perception refers to the perception measurement of the perception target by receiving the perception signal emitted by itself. For example, in wireless communication, self-perception can include the perception of transmission power, the perception of signal quality, etc. For example, the transmitter transmits a perception signal, and the perception signal is received by the transmitter after being reflected by the perception target. The transmitter can obtain the distance of the perception target based on the transmission time and reception time of the perception signal. Self-perception technology has applications in many fields, such as smart transportation, smart cities, smart homes, etc. Self-perception can also be called a single-station perception mode. From the perspective of the perception signal process, the perception site must not only send a perception signal, but also receive the signal reflected by the perception signal on the target surface. Therefore, the single-station perception mode is also called a self-transmitting and self-receiving mode.

[0127] 3. Perception of separation of sending and receiving:

[0128] In this application, separate transmit and receive sensing refers to performing the receiving and transmitting functions independently. Separate transmit and receive sensing can achieve better signal reception and transmission effects, while also reducing system complexity and improving system stability. For example, a separate transmit and receive sensing system consists of two parts: a transmitter and a receiver. The transmitter is responsible for transmitting the sensing signal, which is then reflected by the sensing target and received by the receiver. The receiver processes the sensing signal and obtains information about the sensing target. Separate transmit and receive sensing technology has applications in many fields, such as wireless communications, satellite communications, and radar. This technology can improve the transmission efficiency and reliability of communication systems while also reducing system complexity and cost. Separate transmit and receive sensing can also be called a dual-station sensing mode. In terms of the sensing signal process, the transmitter and receiver of the sensing signal are two different devices. In terms of the sensing signal process, after sensing station A transmits the sensing signal, the signal reflected by the target surface is received by sensing station B. Therefore, the dual-station sensing mode is also called the A-transmit, B-receive mode.

[0129] It can be understood that in a single-station perception scenario, the access network device can send and receive signals by itself, or the terminal device can send and receive signals by itself. In a dual-station perception scenario, the access network device A can send and the access network device B can receive signals, or the access network device can send and the UE can receive signals, or the UE can send and the access network device can receive signals, or UE#1 can send and UE#2 can receive signals.

[0130] Figure 2 is a schematic diagram of perception scenarios applicable to embodiments of the present application. Figure 2 shows six perception scenarios.

[0131] Among them, Figure 2 (a) shows a perception scenario in which access network device A sends and receives the perception signal itself. Access network device A transmits a perception signal, and access network device A receives the reflection signal generated when the perception signal encounters a target in the environment, thereby perceiving the position, speed and other information of the target. Figure 2 (b) shows a perception scenario in which access network device A sends and receives the perception signal, and access network device B receives the reflection signal generated when the perception signal encounters a target in the environment, thereby perceiving the position, speed and other information of the target. Figure 2 (c) shows a perception scenario in which access network device A sends and receives the perception signal, and the terminal device receives the reflection signal generated when the perception signal encounters a target in the environment, thereby perceiving the position, speed and other information of the target.

[0132] Among them, Figure 2 (d) shows a perception scenario in which UEs transmit and receive independently. UE#1 transmits a perception signal, and UE#1 receives the reflection signal generated when the perception signal encounters a target in the environment, thereby perceiving the target's position, speed, and other information. Figure 2 (e) shows a perception scenario in which UE#1 transmits and receives an access network device. UE#1 transmits a perception signal, and access network device B receives the reflection signal generated when the perception signal encounters a target in the environment, thereby perceiving the target's position, speed, and other information. Figure 2 (f) shows a perception scenario in which UE#1 transmits and UE#2 receives. UE#1 transmits a perception signal, and UE#2 receives the reflection signal generated when the perception signal encounters a target in the environment, thereby perceiving the target's position, speed, and other information.

[0133] The above perception scenarios are merely exemplary and do not limit the embodiments of the present application.

[0134] In this application, sensed targets include various tangible objects in the environment that can reflect electromagnetic waves, such as mountains, forests, or buildings. They can also include movable objects such as vehicles, drones, pedestrians, and terminal devices. Sensed targets may also be referred to as targets, detected targets, sensed objects, detected objects, or sensed devices, and are not limited in this application.

[0135] FIG3 is a schematic diagram of a network architecture applicable to an embodiment of the present application.

[0136] As shown in Figure 3, the network architecture includes but is not limited to the following network elements:

[0137] 1. Network exposure function (NEF) network element:

[0138] It is used to securely open the services and capabilities provided by 3GPP network functions to the outside world, mainly supporting the secure interaction between 3GPP networks and third-party applications.

[0139] 2. Application function (AF) network element:

[0140] Used for data routing affected by applications, accessing network open functional network elements, or interacting with the policy framework for policy control, such as influencing data routing decisions, policy control functions, or providing some third-party services to the network side.

[0141] 3. Access and Mobility Management Function (AMF) network element:

[0142] It is mainly used for mobility management and access management, and can be used to implement other functions of the mobility management entity (MME) in the LTE system except session management, such as lawful interception and access authorization / authentication. When the AMF network element provides services for a session in the user equipment, it will provide control plane storage resources for the session to store the session identifier, the SMF network element identifier associated with the session identifier, etc. In the embodiment of the present application, it can be used to implement the functions of the access and mobility management network element.

[0143] 4. User plane function (UPF) network element:

[0144] This network element can be used for packet routing and forwarding, or for quality of service (QoS) processing of user plane data. User data can be accessed through this network element to the data network (DN). User data can also be received from the data network and transmitted to the user device through the access network equipment. The transmission resources and scheduling functions that provide services to the user device in the UPF network element are managed and controlled by the SMF network element. In the embodiments of the present application, this network element can be used to implement the functions of the user plane network element.

[0145] 5. Radio access network (AN):

[0146] The access device in the embodiment of the present application can be a device for communicating with a user equipment. The access device can also be called an access network device or a wireless access network device. For example, the access device can be an evolved NodeB (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the access device can be a relay station, access point, vehicle-mounted device, wearable device, access device in a 5G network, or access device in a future evolved PLMN network, etc. It can be an access point (AP) in a WLAN, or a gNB in ​​an NR system. The embodiment of the present application is not limited. Figure 3 shows two RAN devices, namely RAN1 and RAN2.

[0147] In addition, in the embodiment of the present application, the access device is a device in the RAN, or in other words, a RAN node that connects the user equipment to the wireless network. For example, as an example and not a limitation, the access device can be listed as: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP). In a network structure, the network device may include a centralized unit (CU) node, a distributed unit (DU) node, or a RAN device including a CU node and a DU node, or a RAN device including a control plane CU node (CU-CP node) and a user plane CU node (CU-UP node) and a DU node.

[0148] An access device provides services for a cell, and a user device communicates with the access device through the transmission resources used by the cell (e.g., frequency domain resources, or spectrum resources). The cell may be a cell corresponding to the access device (e.g., a base station). The cell may belong to a macro base station or a base station corresponding to a small cell. Small cells may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0149] In addition, multiple cells can operate simultaneously on the same frequency on a carrier in an LTE or 5G system. In some special scenarios, the concepts of carrier and cell can be considered equivalent. For example, in a carrier aggregation (CA) scenario, when a secondary carrier is configured for a UE, both the carrier index of the secondary carrier and the cell identification (Cell ID) of the secondary cell operating on the secondary carrier are carried. In this case, the concepts of carrier and cell can be considered equivalent, for example, a user equipment accessing a carrier is equivalent to accessing a cell.

[0150] The communication system of the present application can also be applied to vehicle to everything (V2X) technology, that is, the user equipment of the present application can also be a car, for example, a smart car or a self-driving car.

[0151] The "X" in V2X represents different communication goals. V2X can include but is not limited to: vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to network (V2N), and vehicle to pedestrian (V2P).

[0152] In V2X, access devices can configure "zones" for UEs. These zones can also be called geographic regions. Once configured, the world is divided into multiple zones, defined by reference points, length, and width. When determining a zone identifier (ID), the UE uses the zone's length, width, the number of zones in the length, the number of zones in the width, and the reference points. This information can be configured by the access device.

[0153] V2X services can be provided in two ways: using the proximity-based services communication (PC5) interface and the Uu interface. The PC5 interface is defined based on a sidelink, enabling direct communication between communication devices (e.g., vehicles). The PC5 interface can be used both out of coverage (OOC) and in coverage (IC), but only authorized communication devices can use it for transmission.

[0154] The access network device in the present application has perception capabilities and can act as a perception entity to send perception signals to the perception target and receive perception echo signals. It can also receive echo signals from other perception entities, or it can also receive echo signals of perception signals sent by other perception entities. For details, please refer to the scenario in Figure 2, and the embodiments of the present application are not limited to this.

[0155] 6. Sensing service control function (SSCF):

[0156] The main function of SSCF is to receive capability registrations from sensing entities and implement the orchestration of sensing services.

[0157] During the capability registration phase of a sensing entity, the sensing entity may send a capability registration request message to the SSCF. The capability registration request message includes the sensing entity's indication information, indication information of its neighboring sensing entities, the sensing entity's location information, the sensing range of the sensing entity, and other parameters. After registration is completed, the SSCF may send a sensing capability registration response message to the sensing entity to notify the sensing entity of the completion of the sensing capability registration.

[0158] The indication information of the sensing entity may be an identifier or a name of the sensing entity, which is not limited in the embodiment of the present application.

[0159] During the orchestration phase of the perception service, the SSCF can determine the sending entity and receiving entity of the perception signal based on service requirements. For example, the SSCF can select a suitable perception entity as the sending entity based on the perception service request, and send a perception control message to the RAN, which may include the perception signal Tx, the perception type, the KPI of the perception service, etc.; similarly, the SSCF can select a suitable perception entity as the receiving entity based on the perception service request, and send a perception control message to the UE, which may include the perception signal Rx, the perception type, etc.

[0160] SSCF can communicate with other NFs through a service based interface (SBI).

[0161] 7. Sensing data process function (SDPF):

[0162] SDPF is used to process perception service data.

[0163] The perception entity can send the perception raw data to the SDPF, the SDPF can calculate the perception measurement data based on the perception raw data, calculate the perception result based on the perception measurement data, and send the processed result to the DN. For example, it can be sent to the DN through the NEF or gateway (gateway, GW). This embodiment of the present application is not limited to this.

[0164] SDPF can be connected to the SBI bus or a separate interface can be defined.

[0165] In this application, the RAN can be directly connected to the SSCF or forwarded through the AMF, which is not limited in this embodiment of the present application.

[0166] In this application, the perception data of the RAN or UE can be forwarded to the SDPF through the UPF, or can be sent directly to the SDPF, which is not limited in this embodiment of the present application.

[0167] It should be understood that all the network architectures shown above are only exemplary illustrations, and the network architecture applicable to the embodiments of the present application is not limited thereto. Any network architecture that can realize the functions of the above-mentioned network elements is applicable to the embodiments of the present application.

[0168] It should also be understood that the functions or network elements shown in the figure can be understood as network elements used to implement different functions, for example, they can be combined into network slices as needed. These network elements can be independent devices, or they can be integrated into the same device to implement different functions, or they can be network elements in hardware devices, or they can be software functions running on dedicated hardware, or they can be virtualized functions instantiated on a platform (for example, a cloud platform). This application does not limit the specific form of the above network elements.

[0169] It should also be understood that the above naming is defined only to facilitate the distinction between different functions and should not constitute any limitation to this application. This application does not exclude the possibility of adopting other naming in 6G networks and other future networks. For example, in a 6G network, some or all of the above network elements may continue to use the terminology used in 5G, or may adopt other names.

[0170] In this application, in a wireless sensing service scenario involving multiple sensing entities, multiple sensing entities collect data and collaborate to complete the sensing service. Due to the mobility of the sensing target, when it moves out of the effective sensing range of the current sensing entity within the sensing service coverage area, the continuity of the sensing service needs to be guaranteed.

[0171] In view of this, an embodiment of the present application provides a communication method for perception, which can ensure the continuity of wireless perception services when the perception target moves.

[0172] The communication method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings. The embodiment provided by the present application can be applied to the communication system shown in FIG1 above without limitation.

[0173] The solution of this application is described in detail below.

[0174] FIG4 is a schematic diagram of a scenario applicable to an embodiment of the present application.

[0175] The scenario may include SDPF and SSCF.

[0176] The scene may also include multiple sensing entities, such as the SE shown in Figure 4 a , SE b , SE c , the three sensing entities each have a sensing service range.

[0177] The sensing service range of each sensing entity can be understood as an effective sensing coverage area, that is, within this coverage area, the sensing entity can generate valid sensing data for the sensing target. Once the sensing target exceeds the sensing range, the sensing data can be considered invalid.

[0178] In this application, the perception service range of the perception entity is determined according to its respective performance, and the perception service range may be an irregular area. For ease of understanding, the perception service range of the perception entity in this application is illustrated using a circular area as an example.

[0179] In this application, the maximum effective perception distance R relative to the perception entity is determined based on the performance of the perception entity. max As shown in Figure 4, SE a The perceived service scope is SE a The position of the circle is the center, and R max1 Circular area with radius #1; SE b The perceived service scope is SE b The position of the circle is the center, and R max2 Circular area with radius #2; SE c The perceived service scope is SE c The position of the circle is the center, and R max3 When the target moves in area #1, SE a The sensing target can be sensed and the sensing data can be sent to the SDPF; when the sensing target moves in area #2, the SE b The sensing target can be sensed and the sensing data can be sent to the SDPF; when the sensing target moves in area #3, the SE c The sensing target may be sensed and the sensing data may be sent to the SDPF.

[0180] In this application, the SSCF can determine the effective distance R to ensure the continuity of the sensing service based on the service requirements of the sensing service. t As shown in Figure 4, SE a The scope of the perceived business continuity service is SE a The position of the circle is the center, and R t1 Circular area with radius #1';SE b The scope of the perceived business continuity service is SE b The position of the circle is the center, and R t2 Circular area with radius #2';SE c The scope of the perceived business continuity service is SE c The position of the circle is the center, and R t3 When the target moves in the circular area #3' with a radius of a The sensing target can be sensed and the sensing service can be continued. When the sensing target moves in area #2', SE b The sensing target can be sensed and the sensing service can be continued. When the sensing target moves in area #3', SE c Awareness of the awareness target can be performed and awareness service continuity can be ensured.

[0181] Among them, SSCF can determine the effective distance R to ensure the continuity of the perception service based on the service KPI of the perception service. t The distance between the sensing target and the sensing entity does not exceed R t When the distance between the sensing target and the sensing entity exceeds R t When the service is not connected, the continuity of the service may be affected.

[0182] It should be noted that in this application, the effective distance R to ensure the continuity of the perception service is t The maximum effective perception distance R from the perception entity max Differently, once the perception target moves out of the perception service continuity service range, the continuity of the perception service may have been affected, but it may still be within the perception service range. Although the perception data of the perception entity is valid, the continuity of the perception service cannot be guaranteed due to reasons such as weak signal quality or large changes in signal quality.

[0183] In this application, the effective distance R to ensure the continuity of the perception service t It can also be called the maximum scope of the business requirements of the sensing entity for the sensing business.

[0184] The following details the effective distance R based on the assurance of service continuity. t Methods to ensure perceived business continuity.

[0185] Figure 5 is a schematic diagram of a communication method for perception applicable to an embodiment of the present application. For ease of description, method 500 is exemplified below by taking the interaction between a first perception entity / first network device and a second network device and a second perception entity as an example.

[0186] In this application, the perception entity may include access network equipment, terminal equipment and other devices with perception capabilities. When the perception target moves in a scenario where multiple perception entities collaborate to perceive, the multiple perception entities can perceive the perception target within their respective perception ranges. In this application, the multiple perception entities take the first perception entity and the second perception entity as examples, and of course can also include a third perception entity, etc. The embodiments of this application do not limit this.

[0187] Exemplarily, the first network device is a network entity having a perception data processing function, such as an SDPF.

[0188] Exemplarily, the second network device is a network entity having a service-aware control function, such as SSCF.

[0189] S510, a first perception entity or a first network device receives first configuration information.

[0190] In the present application, the second network device may send first configuration information to the first network device or the first perception entity.

[0191] The first configuration information includes a first threshold value, which is used to indicate the perception range of the first perception entity for the first perception service. It should be noted that the perception range for the first perception service is related to the service demand of the first perception service. For example, the higher the service demand (such as service quality requirement) of the first perception service, the smaller the perception range for the first perception service.

[0192] In one possible implementation, the second network device may also send the first configuration information to a perception entity adjacent to the first perception entity, for example, send the first configuration information to the second perception entity, and the first configuration information may also include a second threshold, which is used to indicate the perception range of the second perception entity for the first perception service.

[0193] The first threshold and the second threshold can also be understood as the effective distance to ensure the service continuity of the first perception service, that is, the R t .

[0194] In the present application, the first threshold and the second threshold are determined by the second network device for the first perception entity and the second perception entity respectively based on the service requirements of the first perception service.

[0195] Exemplarily, the second network device determines the first threshold and the second threshold based on a key performance indicator (KPI) of the first perceived service.

[0196] It can be understood that the business requirements of the same perception service (for example, the first perception service) may be different for different perception entities, and therefore the effective distance for ensuring business continuity may also be different. Of course, the effective distance for different perception entities may also be the same, that is, the first threshold and the second threshold may be the same or different, and the embodiments of the present application do not limit this.

[0197] In the present application, the first configuration information may further include information of a third sensing entity adjacent to the first sensing entity. For example, the first configuration information may further include a third threshold, and the first configuration information may be sent to the third sensing entity. This embodiment of the present application does not limit this.

[0198] S520: The first perception entity / first network device determines another perception entity to perform the first perception service based on the first configuration information and the location information of the first perception target.

[0199] In the present application, when the first perception target moves within the perception range of the first perception entity ensuring the continuity of the perception service, the first perception service can be realized based on the perception of the first perception target, that is, the service requirements of the first perception service are met. The first perception entity or the first network device can determine whether the first perception target is currently within the perception range of the first perception entity ensuring the continuity of the perception service based on the location information of the first perception target. The location information of the first perception target is used to indicate the location of the first perception target, for example, it can be the distance information between the first perception target and the first perception entity (or other perception entity), or the physical location coordinate information of the first perception target, or it can be the location information of the first perception target in the signal strength distribution map determined according to the signal strength between it and the first perception entity (or other perception entity), or it can be other information that can represent the physical location of the first perception target or the location of the signal distribution map.

[0200] Exemplarily, the position information of the first sensing target includes a first distance. The first distance is the distance between the position of the first sensing target and the position of the first sensing entity.

[0201] In one possible implementation, the first perception entity or the first network device determines that the first distance exceeds the effective distance for the first perception entity (i.e., the first perception entity) to ensure the continuity of the perception service, and the service continuity of the first perception service may not be able to be maintained. It can be determined that other perception entities perform the first perception service.

[0202] It can be understood that the first perception target is in a mobile state. When the first perception target has moved out of or is about to move out of the perception range that ensures the business continuity of the perception service, in this case, another perception entity can be determined to execute the first perception service to ensure the continuity of the first perception service.

[0203] In one possible implementation, the first perception entity / first network device determines a first distance, and when the first distance is greater than or equal to a first threshold, determines that another perception entity performs a first perception service.

[0204] The first distance is the distance between the first perception target and the first perception entity;

[0205] The first sensing entity may determine the first distance based on the sensing capability.

[0206] Among them, the first network device can obtain the first distance through the first perception entity.

[0207] The following is an exemplary description of how to determine another sensing entity.

[0208] In one possible implementation, the first perception entity / first network device may determine the first request information based on the first configuration information.

[0209] The first request information is used to request the second perception entity to perform the first perception service.

[0210] Furthermore, the first perception entity / first network device may send the first request information to the second perception entity.

[0211] Exemplarily, the first perception entity / first network device may determine the target perception entity, i.e., the second perception entity, based on an algorithm, which is not limited in the embodiments of the present application.

[0212] Among them, the first request information may include indication information of the first perception service, indication information of the first perception entity (for example, the identifier or name of the first perception entity), indication information of the second perception entity (for example, the identifier or name of the second perception service) and perception information.

[0213] In this application, the indication information of the first perception service, for example, can be the identifier or name of the first perception service, or other information indicating the first perception service, which is not limited in this application; the indication information of the first perception entity, for example, can be the identifier or name of the first perception entity, or other information indicating the first perception entity, which is not limited in this application; the indication information of the second perception entity, for example, can be the identifier or name of the second perception entity, or other information indicating the second perception entity, which is not limited in this application. This will not be repeated in the following text.

[0214] In the present application, the first perception entity or the first network device can determine another perception entity to perform the first perception service based on the first configuration information.

[0215] Among them, when the first perceiving entity determines another perceiving entity based on the first configuration information, in one possible manner, the first configuration information may also include indication information of the perceiving entity (for example, the identifier or name of the perceiving entity) and a first discrimination mode. The indication information of the perceiving entity includes indication information of the first perceiving entity and indication information of perceiving entities adjacent to the first perceiving entity, for example, the identifier of the first perceiving entity, the identifier of the second perceiving entity, and the identifier of the third perceiving entity. The first discrimination mode is used to instruct the first perceiving entity to determine another perceiving entity.

[0216] It can be understood that the first discrimination mode instructs the first sensing entity to determine another sensing entity to perform the first sensing service. The first sensing entity can determine the other sensing entity based on the sensing capability information and location information of the adjacent sensing entities.

[0217] Exemplarily, the first configuration information may further include the maximum effective perception distance of the second perception entity and the third perception entity and the location information of the second perception entity and the third perception entity.

[0218] Among them, when the first network device determines another perception entity based on the first configuration information, in another possible manner, the first configuration information may also include indication information of the perception entity identifier (for example, the identifier or name of the perception entity) and a second discrimination mode, and the indication information of the perception entity includes indication information of the first perception entity and indication information of perception entities adjacent to the first perception entity, for example, the identifier of the first perception entity, the identifier of the second perception entity, and the identifier of the third perception entity. The second discrimination mode is used to instruct the first network device to determine another perception entity.

[0219] It can be understood that the second discrimination mode instructs the first network entity to determine another perception entity to perform the first perception service, and the first network device can determine the other perception entity based on the perception capability information and location information of the perception entity adjacent to the first perception entity.

[0220] Exemplarily, the first configuration information may further include the maximum effective perception distance of the second perception entity and the third perception entity and the location information of the second perception entity and the third perception entity.

[0221] In this application, the second perception entity receives the first request information and performs perception of the first perception target according to the first request information.

[0222] It can be understood that the first perception target may be in a moving state. When the first perception target has entered the perception range of the second perception entity for the business needs of the first perception business, the first perception entity may stop perception.

[0223] In the present application, the second perception entity or the first network device can determine whether the first perception target is currently within the perception range of the second perception entity to ensure the continuity of the perception service based on the location information of the first perception target.

[0224] Exemplarily, the position information of the first sensing target includes a second distance. The second distance is the distance between the position of the first sensing target and the position of the second sensing entity.

[0225] In one possible implementation, when the second perception entity or the first network device determines that the second distance is less than the second threshold, a second request message may be sent to the first perception entity, where the second request message is used to request the first perception entity to stop executing the first perception service.

[0226] It can be understood that the second perception entity can determine by itself that the first perception target has entered the perception range of the second perception entity for the business needs of the first perception service, or the first network device can determine based on the perception data that the first perception target has entered the perception range of the second perception entity for the business needs of the first perception service, thereby instructing the second perception entity to stop perception.

[0227] Correspondingly, the first perception entity receives the second request information sent by the second perception entity or the first network device, and stops executing the first perception service.

[0228] It should be understood that before the first sensing entity receives the second request information, both the first sensing entity and the second sensing entity sense the first sensing target and send sensing data to the SDPF.

[0229] Exemplarily, as shown in Figure 4, when the perception target moves out of area 1' and is about to enter area 2', and moves between area 1' and area 2', the first perception entity and the second perception entity simultaneously perform the first perception service. When the perception target enters area 2', that is, the second distance is less than the second threshold, the first perception entity can stop performing the first perception service.

[0230] In the present application, when the first perception entity or the first network device determines another perception entity, it may also request the second network device to determine the second perception entity.

[0231] In one possible implementation, the first perception entity / first network device may send third request information to the second network device, where the third request information is used to request the second network device to determine the second perception entity.

[0232] The third request information includes indication information of the first perception service, indication information of the first perception entity and perception information.

[0233] Among them, the first configuration information also includes indication information of the first perception service and a third judgment mode, and the third judgment mode is used to instruct the second network device to determine the second perception entity.

[0234] It can be understood that the third determination mode instructs the second network device to determine another perception entity to perform the first perception service, and the second network device can determine the other perception entity based on the perception capability information and location information of the perception entity adjacent to the first perception entity.

[0235] It should be noted that the second network device can obtain indication information (for example, identification or name of each perception service), perception capability information and location information of the first perception entity and the perception entities adjacent to the first perception entity during the registration phase.

[0236] Exemplarily, the second network device may obtain the maximum effective perception distances of the first perception entity, the second perception entity, and the third perception entity, as well as location information of the second perception entity and the third perception entity.

[0237] In the present application, the second network device can determine the target perception entity, that is, the second perception entity, based on an algorithm, and the embodiments of the present application are not limited to this.

[0238] In one possible implementation, the second network device sends fourth request information to the second perception entity, where the fourth request information is used to request the second perception entity to perform the first perception service.

[0239] The fourth request information includes indication information of the first perception service, indication information of the first perception entity, indication information of the second perception entity and perception information.

[0240] In this application, the second perception entity receives the fourth request information and performs perception of the first perception target according to the fourth request information.

[0241] It can be understood that the first perception target may be in a moving state. When the first perception target has entered the perception range of the second perception entity for the business needs of the first perception business, the first perception entity may stop perception.

[0242] In one possible implementation, when the second perception entity determines that the second distance is less than the second threshold, the second perception entity can send a second request message to the first perception entity, and the second request message is used to request the first perception entity to stop executing the first perception service; it can also send a fifth request message to the second network device, and the fifth request message is used to request the first perception entity to stop executing the first perception service. The second network device can send a sixth request message to the first perception device, and the sixth request message is used to request the first perception entity to stop executing the first perception service.

[0243] The second distance is the distance between the first perception target and the second perception entity.

[0244] Correspondingly, the first perception entity receives the second request information or the sixth request information sent by the second perception entity or the second network device, and stops executing the first perception service.

[0245] It should be understood that before the first perception entity receives the second request information or the sixth request information, the first perception entity and the second perception entity simultaneously perceive the first perception target and send perception data to the SDPF.

[0246] In the present application, the first perception entity and the second perception entity may be access network devices or terminal devices, the first network device may be a perception data processing function, and the second network device may be a perception service control function.

[0247] In the above scheme, it is explained that the first perception entity or the first network device determines another perception entity to perform the first perception service based on the effective distance of the service requirements for the first perception service. Next, the specific schemes for different scenarios are described in detail.

[0248] First, an exemplary solution in which a first sensing entity determines another sensing entity to perform a first sensing service is introduced.

[0249] FIG6 is a schematic diagram of a communication method for perception applicable to an embodiment of the present application.

[0250] In this embodiment, the perception entities include perception entity #1, perception entity #2, and perception entity #3; the first network device takes SDPF as an example, the second network device takes SSCF as an example, and the first perception service takes perception service #A as an example.

[0251] Method 600 may specifically include the following steps.

[0252] S610, SSCF sends configuration information #1 to perception entity #1, perception entity #2 and perception entity #3.

[0253] Configuration information #1 may include indication information of sensing service #A, indication information of sensing entity #1, indication information of sensing entity #2, indication information of sensing entity #3, and the sensing scope of all sensing entities for the service requirements of sensing service #A (R of sensing entity #1). t1 , R of perceived entity #2 t2 , R of perceived entity #3 t3 ).

[0254] Among them, the indication information of perception service #A, for example, can be the identifier or name of perception service #A; the indication information of perception entity #1, for example, can be the identifier or name of perception entity #1; the indication information of perception entity #2, for example, can be the identifier or name of perception entity #2.

[0255] In the following, to avoid redundancy, the indication information of perception service #A takes the identifier of perception service #A as an example, the indication information of perception entity #1 takes the identifier of perception entity #1 as an example, and the indication information of perception entity #2 takes the identifier of perception entity #2 as an example.

[0256] In an optional understanding, the SSCF sends the sensing scope of the service requirements of the sensing entity #1 and the adjacent sensing entities for the sensing service #A to each sensing entity.

[0257] The configuration information #1 is used to send the sensing scope of the sensing entity #1 and the adjacent sensing entities for the service requirements of the sensing service #A to each sensing entity. That is, the configuration information #1 may include the service identifier of the sensing service #A, the identifier of the sensing entity #1, the identifier of the sensing entity #2, the identifier of the sensing entity #3, and the identifier of the sensing entity #4. t1 , R t2 , R t3 ).

[0258] Among them, R t1 is an example of the first threshold, which is used to indicate the sensing range of the sensing entity #1 for the service demand of the sensing service #A; t2 is an example of the second threshold, which is used to indicate the sensing range of the sensing entity #2 for the service demand of the sensing service #A; t3 This is an example of the third threshold, which is used to indicate the perception range of the service demand of the perception entity #3 for the perception service #A.

[0259] It should be understood that the above R t1 , R t2 , R t3It is determined by SSCF based on the business needs of perception service #A, that is, when the perception target moves out of the perception range corresponding to the current perception entity that ensures the continuity of the perception service, the business continuity may be affected. At this time, the perception data of the current perception entity may be invalid. In this case, it can be determined that another perception entity will continue to execute the perception service #A.

[0260] It can be understood that the maximum perception range of the perception entity is greater than the perception range that ensures the continuity of the perception business. The perception target moves out of the perception range that ensures the continuity of the perception business, but is still within the maximum perception range of the perception entity. At this time, due to the distance problem of the perception target, the continuity of the perception business may not be guaranteed, and the perception data of the perception entity may also be invalid.

[0261] The configuration information #1 may further include a determination mode #1, where the determination mode #1 is used to instruct the sensing entity #1 to determine another sensing entity to perform the sensing service #A.

[0262] The configuration information #1 may also include the maximum effective sensing distance R of the sensing entity #1. max1 , the maximum effective perception distance R of the perception entity #2 max2 , the maximum effective perception distance R of the perception entity #3 max3 .

[0263] Among them, configuration information #1 can also include location information of perception entity #1, perception entity #2, and perception entity #3.

[0264] S620, perception entity #1, perception entity #2, and perception entity #3 send a response message #1 to the SSCF.

[0265] After receiving the configuration information #1, each perception entity may send a response message #1 to the SSCF.

[0266] S630, the sensing entity #1 determines that the sensing entity #2 performs the sensing service #A according to the configuration information #1 and the location information of the sensing target.

[0267] SSCF can activate perception entity #1 to perform perception service #A. For example, SSCF can determine that perception entity #1 can be activated to perform perception service #A based on the service requirements of perception service #A and the location information of the current perception target.

[0268] Sensing entity #1 executes sensing service #A and sends sensing data to SDPF.

[0269] Perception entity #1 determines the distance between the current perception target and the position of perception entity #1 based on the perception data as R1. When R1 is greater than or equal to R t1When the sensing entity #1 determines that the sensing service #A is performed by another sensing entity.

[0270] It can be understood that when R1 is greater than or equal to R t1 When the perception entity #1 determines that the perception target has moved out of or is about to move out of the perception range that ensures the business continuity of the perception service, in this case, another perception entity can be determined to execute the perception service #A to ensure the continuity of the perception service #A.

[0271] Exemplarily, sensing entity #1 may determine sensing entity #2 to perform sensing service #A according to an algorithm.

[0272] It can be understood that the sensing entity #1 can determine the sensing entity that performs the sensing service #A based on the maximum effective sensing distances of the sensing entities #2 and #3 and the location information of the sensing entities #2 and #3.

[0273] Perception entity #1 may also determine perception entity #2 in other ways, which is not limited in this embodiment of the present application.

[0274] S640, the perception entity #1 sends request information #1 to the perception entity #2.

[0275] Request information #1 is used to request the perception entity #2 to execute the perception service #A.

[0276] Among them, the request information #1 may include the service identifier of the perception service #A, the identifier of the perception entity #1, the identifier of the perception entity #2, perception information, etc.

[0277] S650, perception entity #2 executes perception service #A.

[0278] The sensing entity #2 performs the sensing service #A based on the request information #1.

[0279] Sensing entity #2 uploads the sensing data to SDPF.

[0280] When perception entity #2 executes perception service #A, it can judge by itself that the perception target has entered the perception range of perception entity #2 for the business needs of the first perception service, or the SDPF can judge based on the perception data that the perception target has entered the perception range of perception entity #2 for the business needs of the first perception service, thereby instructing perception entity #1 to stop perception.

[0281] The determining and instructing the sensing entity #1 to stop sensing by the sensing entity #2 may specifically include the following steps S660a and S670a. The determining and instructing the sensing entity #1 to stop sensing by the SDPF may include the following steps S660b and S670b.

[0282] S660a, the sensing entity #2 determines that R2 is less than or equal to R according to the configuration information #1. t2 .

[0283] Based on the perception data, the perception entity #2 determines that the distance between the current perception target position and the perception entity #2 position is R2. When R2 is less than or equal to R t2 , the sensing entity #2 determines that the sensing entity #1 can stop executing the sensing service #A.

[0284] It can be understood that when R2 is less than or equal to R t2 When the perception entity #2 detects that the perception target has entered the perception range of the perception entity #2 for the business needs of the first perception business, in this case, it can be determined that another perception entity can stop executing the perception business #A, and the perception entity #2 can ensure the continuity of the perception business #A.

[0285] S660b, SDPF determines that R2 is less than or equal to R according to configuration information #1. t2 .

[0286] SDPF determines the distance between the current position of the sensing target and the position of the sensing entity #2 as R2 based on the sensing data of the sensing entity #2. When R2 is less than or equal to R t2 , SDPF determines that perception entity #1 can stop executing perception service #A.

[0287] It should be understood that the SSCF can send configuration information #1 to the SDPF and determine the R t2 .

[0288] In one possible implementation, the perception entity #2 starts executing the perception service #A and sends a perception response message to the SDPF. The SDPF determines that the perception entity #1 can stop executing the perception service #A.

[0289] Either step S660a or step S660b can be performed.

[0290] When the perception entity #2 or the SDPF determines that the perception entity #1 can stop executing the perception service #A, it can instruct the perception entity #1 to stop executing the perception service #A.

[0291] S670a, perception entity #2 sends request information #2 to perception entity #1.

[0292] Request information #2 is used to instruct the perception entity #1 to stop executing the perception service #A.

[0293] In a possible implementation, the sensing entity #2 may send a sensing response message to the sensing entity #1, and the sensing entity #1 stops executing the sensing service #A according to the response message.

[0294] The request information #2 may include the identifier of the perception service #A.

[0295] S670b, SDPF sends request information #2 to perception entity #1.

[0296] Request information #2 is used to instruct the perception entity #1 to stop executing the perception service #A.

[0297] The request information #2 may include the identifier of the perception service #A.

[0298] Either step S670a or step S670b can be performed.

[0299] S680, the perception entity #1 stops executing the perception service #A according to the request information #2.

[0300] Before receiving request information #2, perception entity #1 can execute perception service #A simultaneously with perception entity #2. When the perception target has entered the perception range where perception entity #2 can ensure the business continuity of the perception service, perception entity #1 stops executing perception service #A.

[0301] Based on the above technical solution, perception entity #1 can determine another perception entity to continue to perform the perception service based on the configured perception range that ensures the continuity of the perception service. When the perception target enters the perception range where another perception entity can ensure the business continuity of the perception service, perception entity #1 stops perceiving, thereby ensuring the continuous upload of effective perception data of the perception service, meeting the needs of the perception service, and improving the perception capability.

[0302] Next, an exemplary solution in which the SDPF determines another perception entity to perform the first perception service is introduced.

[0303] FIG7 is a schematic diagram of a communication method for perception applicable to an embodiment of the present application.

[0304] In this embodiment, the perception entities include perception entity #1, perception entity #2, and perception entity #3; the first network device takes SDPF as an example, the second network device takes SSCF as an example, and the first perception service takes perception service #A as an example.

[0305] Method 700 may specifically include the following steps.

[0307] Configuration information #2 may include indication information of sensing service #A, indication information of sensing entity #1, indication information of sensing entity #2, indication information of sensing entity #3, and the sensing scope of all sensing entities for the service requirements of sensing service #A (R of sensing entity #1). t1 , R of perceived entity #2 t2 , R of perceived entity #3 t3 ).

[0308] Among them, the indication information of perception service #A, for example, can be the identifier or name of perception service #A; the indication information of perception entity #1, for example, can be the identifier or name of perception entity #1; the indication information of perception entity #2, for example, can be the identifier or name of perception entity #2.

[0309] In the following, to avoid redundancy, the indication information of perception service #A takes the identifier of perception service #A as an example, the indication information of perception entity #1 takes the identifier of perception entity #1 as an example, and the indication information of perception entity #2 takes the identifier of perception entity #2 as an example.

[0310] In an optional understanding, the SSCF sends the sensing scope of the sensing entity #1 and the adjacent sensing entities for the service requirements of the sensing service #A to the SDPF.

[0311] The sensing scope of the sensing entity #1 and the adjacent sensing entities for the sensing service #A is sent to the SDPF through the configuration information #2. That is, the configuration information #2 may include the service identifier of the sensing service #A, the identifier of the sensing entity #1, the identifier of the sensing entity #2, and the identifier of the sensing entity #3. t1 , R t2 , R t3 ).

[0312] Among them, R t1 is an example of the first threshold, which is used to indicate the sensing range of the sensing entity #1 for the service demand of the sensing service #A; t2 is an example of the second threshold, which is used to indicate the sensing range of the sensing entity #2 for the service demand of the sensing service #A; t3 This is an example of the third threshold, which is used to indicate the perception range of the service demand of the perception entity #3 for the perception service #A.

[0313] It should be understood that the above R t1 , R t2 , R t3It is determined by SSCF based on the business needs of perception service #A, that is, when the perception target moves out of the perception range of the business needs of the perception service corresponding to the current perception entity, business continuity may be affected. At this time, the perception data of the current perception entity may be invalid. In this case, it can be determined that another perception entity will continue to execute the perception service #A.

[0314] It can be understood that the maximum perception range of the perception entity is greater than the perception range that ensures the continuity of the perception business, or the perception range of the business needs of the perception business. The perception target moves out of the perception range that ensures the continuity of the perception business, but is still within the maximum perception range of the perception entity. At this time, due to the distance problem of the perception target, the continuity of the perception business may not be guaranteed, and the perception data of the perception entity may also be invalid.

[0315] The configuration information #2 may further include a determination mode #2, where the determination mode #2 is used to instruct the SDPF to determine another perception entity to execute the perception service #A.

[0316] The configuration information #2 may also include the maximum effective sensing distance R of the sensing entity #1. max1 , the maximum effective perception distance R of the perception entity #2 max2 , the maximum effective perception distance R of the perception entity #3 max3 .

[0317] Among them, configuration information #2 can also include location information of perception entity #1, perception entity #2, and perception entity #3.

[0320] S730, SDPF determines that the sensing entity #2 performs the sensing service #A according to the configuration information #2 and the location information of the sensing target.

[0321] SSCF can activate perception entity #1 to perform perception service #A. For example, SSCF can determine that perception entity #1 can be activated to perform perception service #A based on the service requirements of perception service #A and the location information of the current perception target.

[0322] Sensing entity #1 executes sensing service #A and sends sensing data to SDPF.

[0323] SDPF can determine the distance between the current position of the sensing target and the position of the sensing entity #1 as R1 based on the sensing data. When R1 is greater than or equal to R t1When , SDPF determines that another perception entity performs perception service #A.

[0324] It can be understood that when R1 is greater than or equal to R t1 When , SDPF can determine that the perception target has moved out of or is about to move out of the perception range that ensures the business continuity of the perception service. In this case, another perception entity can be determined to execute perception service #A to ensure the continuity of the perception service #A.

[0325] Exemplarily, the SDPF may determine the perception entity #2 according to an algorithm to perform the perception service #A.

[0326] The SDPF may also determine the perception entity #2 in other ways, which is not limited in this embodiment of the present application.

[0327] S740, SDPF sends request information #1 to perception entity #2.

[0328] Request information #1 is used to request the perception entity #2 to execute the perception service #A.

[0329] Among them, the request information #1 may include the service identifier of the perception service #A, the identifier of the perception entity #1, the identifier of the perception entity #2, perception information, etc.

[0337] Based on the perception data, the perception entity #2 determines that the distance between the current perception target position and the perception entity #2 position is R2. When R2 is less than or equal to R t2 , the sensing entity #2 determines that the sensing entity #1 can stop executing the sensing service #A.

[0338] It can be understood that when R2 is less than or equal to R t2 When the perception entity #2 determines that the perception target has entered the perception range that ensures the business continuity of the perception service, in this case, it can be determined that another perception entity can stop executing perception service #A, and perception entity #2 can ensure the continuity of the perception service #A.

[0354] Before receiving request information #2, perception entity #1 can execute perception service #A simultaneously with perception entity #2. When the perception target has entered the perception range where perception entity #2 can ensure the business continuity of the perception service, perception entity #1 stops executing perception service #A.

[0355] Based on the above technical solution, SDPF, as a data processing network element, can determine another perception entity to continue to perform the perception service based on the configured perception range that ensures the continuity of the perception service and the perception data uploaded by the perception entity. When the perception target enters the perception range where another perception entity can ensure the business continuity of the perception service, perception entity #1 stops perception, thereby ensuring the continuous upload of effective perception data of the perception service, meeting the needs of the perception service, and improving the perception capability.

[0356] Next, an exemplary solution in which the SSCF determines another perception entity to perform the first perception service is introduced.

[0357] FIG8 is a schematic diagram of a communication method for perception applicable to an embodiment of the present application.

[0358] In this embodiment, the perception entities include perception entity #1, perception entity #2, and perception entity #3; the first network device takes SDPF as an example, the second network device takes SSCF as an example, and the first perception service takes perception service #A as an example.

[0359] Method 800 may specifically include the following steps.

[0360] S810, SSCF sends configuration information #3 to perception entity #1, perception entity #2 and perception entity #3.

[0361] Among them, configuration information #3 may include indication information of perception service #A, and for different perception entities, may also include the perception scope of each perception entity for the business requirements of perception service #A.

[0362] The indication information of the perception service #A may be, for example, the identifier or name of the perception service #A.

[0363] In the following, to avoid redundancy, the indication information of the perception service #A takes the identifier of the perception service #A as an example.

[0364] In an optional understanding, the SSCF sends the sensing scopes of the service requirements of the sensing service #A to different sensing entities respectively.

[0365] The configuration information #3 is used to send the perception scope of each service requirement of the perception service #A to different perception entities. That is, the configuration information #3 sent by SSCF to perception entity #1 may include the service identifier and R t1 ; The configuration information #3 sent by SSCF to the perception entity #2 may include the service identifier of the perception service #A and R t2 ; The configuration information #3 sent by SSCF to the perception entity #3 may include the service identifier of the perception service #A and R t3 .

[0366] Among them, R t1 is an example of the first threshold, which is used to indicate the sensing range of the sensing entity #1 for the service demand of the sensing service #A; t2 is an example of the second threshold, which is used to indicate the sensing range of the sensing entity #2 for the service demand of the sensing service #A; t3 This is an example of the third threshold, which is used to indicate the perception range of the service demand of the perception entity #3 for the perception service #A.

[0367] It should be understood that the above R t1 , R t2 , R t3 It is determined by SSCF based on the business needs of perception service #A, that is, when the perception target moves out of the perception range of the business needs of perception service #A corresponding to the current perception entity, business continuity may be affected. At this time, the perception data of the current perception entity may be invalid. In this case, it can be determined that another perception entity will continue to execute the perception service #A.

[0368] It can be understood that the maximum perception range of the perception entity is greater than the perception range that ensures the continuity of the perception business. The perception target moves out of the perception range that ensures the continuity of the perception business, but is still within the maximum perception range of the perception entity. At this time, due to the distance problem of the perception target, the continuity of the perception business may not be guaranteed, and the perception data of the perception entity may also be invalid.

[0369] The configuration information #3 may further include a determination mode #3, and the determination mode #3 is used to instruct the SSCF to determine another perception entity to perform the perception service #A.

[0370] S820, perception entity #1, perception entity #2 and perception entity #3 send response message #3 to SSCF.

[0371] After receiving configuration information #3, perception entity #1, perception entity #2 and perception entity #3 may send response message #3 to SSCF.

[0372] S830: The sensing entity #1 determines that R1 is greater than or equal to R according to the configuration information #3 and the location information of the sensing target. t1 .

[0373] SSCF can activate perception entity #1 to perform perception service #A. For example, SSCF can determine that perception entity #1 can be activated to perform perception service #A based on the service requirements of perception service #A and the location information of the current perception target.

[0374] Sensing entity #1 executes sensing service #A and sends sensing data to SDPF.

[0375] The sensing entity #1 determines based on the sensing data that the distance R1 between the current sensing target position and the sensing entity #1 position is greater than or equal to R t1 .

[0376] An optional understanding is that perception entity #1 can determine that the current location of the perception target has moved out of or is about to move out of the perception range that ensures the business continuity of the perception service. In this case, it can request the control network element to determine another perception entity to execute perception service #A to ensure the continuity of the perception service #A.

[0377] S840, perception entity #1 sends request information #3 to SSCF.

[0378] Perceiving entity #1 based on R1 being greater than or equal to R t1 Send request information #3 to the SSCF, where the request information #3 is used to request the SSCF to determine another perception entity to perform perception service #A.

[0379] The request information #3 may include the identifier of the perception service #A, the identifier of the perception entity #1, the location information of the perception target, and the like.

[0380] S850, SSCF determines the second perception entity according to request information #3.

[0381] Exemplarily, the SSCF may determine the perception entity #2 to perform the perception service #A according to an algorithm.

[0382] The SSCF may also determine the perception entity #2 in other ways, which is not limited in this embodiment of the present application.

[0383] It should be noted that the SSCF may obtain indication information, sensing capability information, and location information of the sensing entity #1 and adjacent sensing entities during the registration phase.

[0384] The indication information of the perception entity may be an identifier or name of the perception entity, or other information indicating the perception entity, which is not limited in the embodiment of the present application.

[0385] Exemplarily, the SSCF may obtain the maximum effective sensing distance and location information of sensing entity #1, sensing entity #2, and sensing entity #3.

[0386] The SSCF may determine the sensing entity #2 to perform the sensing service #A based on the indication information, sensing capability information, and location information of the sensing entity #1 and the adjacent sensing entities.

[0387] S860, SSCF sends request information #4 to perception entity #2.

[0388] Request information #4 is used to request the perception entity #2 to execute the perception service #A.

[0389] Among them, the request information #4 may include the service identifier of the perception service #A, the identifier of the perception entity #1, the identifier of the perception entity #2, perception information, etc.

[0390] S870, perception entity #2 executes perception service #1.

[0391] The sensing entity #2 performs the sensing service #A based on the request information #4.

[0392] S880, the sensing entity #2 determines that R2 is less than or equal to R according to the configuration information #3. t2 .

[0393] Sensing entity #2 uploads the sensing data to SDPF.

[0394] Based on the perception data, the perception entity #2 determines that the distance between the current perception target position and the perception entity #2 position is R2. When R2 is less than or equal to R t2 , the sensing entity #2 determines that the sensing entity #1 can stop executing the sensing service #A.

[0395] When executing perception service #A, perception entity #2 can determine that the perception target has entered the perception range that ensures the service continuity of the perception service, and thus can instruct perception entity #1 to stop perception, or can instruct perception entity #1 to stop perception through SSCF.

[0396] Instructing the perception entity #1 to stop perception through the SSCF may specifically include the following steps S890a and S891a; and the perception entity #2 instructing the perception entity #1 to stop perception may specifically include the following step S891b.

[0397] S890a, perception entity #2 sends request information #5 to SSCF.

[0398] The request information #5 is used to instruct the perception entity #1 to stop executing the perception service #A.

[0399] In a possible implementation, the perception entity #2 may send a perception response message to the SSCF, and the SSCF instructs the perception entity #1 to stop executing the perception service #A according to the response message.

[0400] The request information #5 may include the identifier of the perception service #A.

[0401] S891a, SSCF sends request information #6 to perception entity #1.

[0402] The request information #6 is used to instruct the perception entity #1 to stop executing the perception service #A.

[0403] In a possible implementation, the SSCF may send a perception response message to the perception entity #1, and the perception entity #1 stops executing the perception service #A according to the response message.

[0404] The request information #6 may include the identifier of the perception service #A.

[0405] S891b, perception entity #2 sends request information #6 to perception entity #1.

[0406] Perceiving entity #2 can be based on R2 being less than or equal to R t2 The result determines that the sensing target has entered the sensing range of sensing entity #2 that ensures the continuity of sensing service, and instructs sensing entity #1 to stop sensing.

[0407] In a possible implementation, the sensing entity #2 may send a sensing response message to the sensing entity #1, and the sensing entity #1 stops executing the sensing service #A according to the response message.

[0408] S892, the perception entity #1 stops executing the perception service #1 according to the request information #6.

[0409] Before receiving request information #2, perception entity #1 can execute perception service #A simultaneously with perception entity #2. When the perception target has entered the perception range where perception entity #2 can ensure the business continuity of the perception service, perception entity #1 stops executing perception service #A.

[0410] Based on the above technical solution, perception entity #1 can request SSCF to determine another perception entity to continue to perform the perception service based on the configured perception range that ensures the continuity of the perception service. When the perception target enters the perception range where another perception entity can ensure the business continuity of the perception service, perception entity #1 stops perceiving, thereby ensuring the continuous upload of effective perception data of the perception service, meeting the needs of the perception service, and improving the perception capability.
