Description

Communication method and device

[0001] This application claims priority to Chinese patent application number 202410070910.0, filed on January 17, 2024, entitled “Communication Method and Device,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the field of communications, and in particular to a communication method and device. Background Art

[0003] In a communication system, the transmitter modulates electromagnetic wave signals so that they carry information about the source. During propagation, these signals are affected by the wireless environment, meaning they are modulated by the environment and thus carry environmental information. By analyzing these signals, the receiver can not only obtain the source information but also extract perceptual information reflecting the characteristics of the propagation environment. This makes integrated sensing and communication (ISAC) possible.

[0004] The objects used to acquire sensory data in the system are called sensory entities. These entities can include access network devices, terminal devices, and other devices. The sensory data acquired by these sensory entities can provide data support for sensory services. The greater the number of sensory entities, or the richer the sensory entity resources, the richer the sensory data provided for sensory services.

[0236] Perception is the process of collecting and processing data to generate perception results. For example, collected data can be used to determine the distance, shape, and type of surrounding obstacles. Another example is the use of collected data to determine the breathing rate and heart rate of the monitored subject. The collected data can be collected by sensors or wireless signals. The process of performing perception through wireless signal data collection is also called wireless perception.

[0237] Wireless sensing and wireless communications are both based on electromagnetic wave theory. In a communication system, the transmitter can modulate the electromagnetic wave signal so that the electromagnetic wave carries the source information. During propagation, the electromagnetic wave signal is affected by the wireless environment, that is, the electromagnetic wave signal is modulated by the environment and therefore also carries environmental information. By analyzing the electromagnetic wave signal, the receiver can not only obtain the carried source information but also extract the perception information reflecting the characteristics of the propagation environment. This makes integrated sensing and communication (ISAC) possible. ISAC can also be called joint communications and sensing (JCAS) or synaesthesia integration. Compared with systems that separate sensing and communication, ISAC has a series of advantages, such as cost savings, reduced equipment size, lower power consumption, improved frequency efficiency, and reduced mutual interference between communication and sensing.

[0238] By utilizing the perception capabilities of the communication system, perception data can be provided to consumers of the perception data. For example, consumers of the perception data can use the perception data to implement various functions and services.

[0239] For example, a consumer of perception data refers to an object or entity that requests or consumes perception data, or is described as a consumer or user of a perception service. Data requesters may also be referred to as data consumers, data users, data consumers, perception subscribers, perception subscribers, etc., and this application does not impose any restrictions on these terms.

[0240] In some possible scenarios, the consumer of perception data may be a third-party entity, such as a server, terminal device, data processing system, etc.

[0241] For example, in embodiments of the present application, sensory data can be used to implement one or more services and functions, including high-precision positioning and tracking, simultaneous imaging, map construction and positioning, human sensory enhancement, and gesture and motion recognition. Third-party entities can be servers, systems, devices, and the like used to implement the aforementioned services and functions, such as positioning systems and autonomous driving systems.

[0242] In other possible scenarios, the consumer of the perception data may also be a network function (NF) element or entity within the network, such as an application function (AF) element or entity, or a data network (DN).

[0243] This application does not limit the specific type of consumers of perception data.

[0244] In the aforementioned scenario of acquiring perception data using a communication system, the objects in the communication system used to acquire perception data can be referred to as perception entities. These entities can include access network devices, terminal devices, and so on. The perception data acquired by these perception entities can provide data support for perception services. The greater the number of perception entities, or the richer the perception entity resources, the richer the perception data provided for perception services.

[0245] This application provides a communication method that enables different operator networks to share perception entities to obtain perception data. For example, operator A's network can use the perception entity in operator B's network to obtain perception data.

[0246] It should be understood that for one operator network, perception data can be obtained by using perception entities in one or more other operator networks. For example, there can be multiple operator networks B. This embodiment of the application will use the example of obtaining perception data by using a perception entity in another operator network as an example, but this is not a limitation.

[0247] For example, the communication method provided in the embodiment of the present application can be applied to interaction between the communication systems of two operator networks. Figure 1 is a schematic diagram of a communication system provided in the embodiment of the present application. The communication system of each operator network can refer to Figure 1.

[0248] As shown in Figure 1, the communication system may include: an access network (radio access network, RAN) network element 110, a sensing service control function (SSCF) network element 120, a sensing data processing function (SDPF) network element 130, a network storage function (NRF) network element 140, a security edge protection proxy (SEPP) 150, an access and mobility management function (AMF) network element 160, a session management function (SMF) network element 170, a user plane function (UPF) network element 180, etc.

[0249] The RAN network element 110 may be a network element in an access network (also called a radio access network), such as an access network device. The RAN network element 110 may also be called a RAN node (or device).

[0250] In one possible scenario, the RAN network element 110 may be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next generation NodeB (gNB), a next generation base station in a 6G system, a base station in a future mobile communication system, a satellite, an integrated access and backhaul (IAB) node, a mobile switching center, or an access network device in a non-terrestrial network (NTN) communication system, that is, it may be deployed on a high-altitude platform or a satellite. The RAN network element 110 may be a macro base station, a micro base station, an indoor station, a relay node or a donor node, or a wireless controller in a cloud radio access network (CRAN) scenario. The RAN network element 110 may also be a device that functions as a base station in device-to-device (D2D) communication, vehicle-to-vehicle communication, drone communication, or machine communication. Optionally, the RAN network element 110 may also be a server, a wearable device, a vehicle or an onboard device, etc. For example, the RAN network element 110 in the vehicle to everything (V2X) technology may be a road side unit (RSU).

[0251] All or part of the functions of the RAN network element 110 in this application may also be implemented through software functions running on hardware, or through virtualized functions instantiated on a platform (e.g., a cloud platform). The RAN network element 110 in this application may also be a logical node, logical module, or software that can implement all or part of the functions of the RAN network element 110.

[0252] In another possible scenario, the RAN network element 110 may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be separately configured or included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It is understood that the RAN network element 110 may be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU may be classified as a network device in the access network RAN, or the CU may be classified as a network device in the core network CN, without limitation herein.

[0253] In different systems, CU (or CU-CP and CU-UP), DU or RU may have different names, but those skilled in the art can understand their meanings. For example, in an open access network (open RAN, O-RAN or ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. Any unit among CU (or CU-CP, CU-UP), DU and RU can be implemented by a software module, a hardware module, or a combination of software and hardware modules.

[0254] The SSCF network element 120 and SDPF network element 130 shown in Figure 1 may be core network functional modules. The SSCF network element 120 implements control plane functions for sensory services, such as receiving sensory capability information from sensory entities and orchestrating sensory services based on this information. Sensory services are also called sensory services. The SDPF network element 130 implements data plane functions for sensory services, such as processing sensory data to obtain sensory results.

[0255] In an embodiment of the present application, a sensing entity (SE) is a logical entity, which may also be referred to as a logical sensing entity. In a sensing scenario, sensing entities are divided into sensing entities that send sensing signals (such as Tx) and sensing entities that receive sensing signals (such as Rx). The sensing signals may be the aforementioned electromagnetic wave signals. The sensing entity that sends the sensing signal may be referred to as a sending sensing entity, and the sensing entity that receives the sensing signal may be referred to as a receiving sensing entity. The sensing signal received by the receiving sensing entity carries the sensing data. In some scenarios, a sensing entity may serve as both a sending sensing entity and a receiving sensing entity, that is, a sensing entity may have the functions of sending and receiving sensing signals at the same time. For example, the sensing entity may send and receive the sensing signals by itself.

[0256] The aforementioned sensing entities can be deployed on network devices or terminal devices. That is, network devices and / or terminal devices with sensing capabilities can serve as sensing entities, or the sensing entities can include network devices and / or terminal devices with sensing capabilities. Different sensing entities can form different sensing scenarios.

[0257] For example, Figure 2 shows a schematic diagram of a perception scenario provided by an embodiment of the present application. As shown in Figure 2, based on the type of the perception entity, the perception scenario can include six types shown in (a) to (f) in Figure 2.

[0258] In scenario 1, shown in (a) of Figure 2, a network device (e.g., a base station) can act as both a sensing entity that sends and receives sensing signals. That is, the network device can simultaneously act as both a transmitter (Tx) and receiver (Rx) of sensing signals. The sensing signal sent by the network device reaches a target object (e.g., a vehicle, a person, or other object, with a vehicle being used as an example in Figure 2). After being reflected by the target object, the network device receives the sensing signal and processes it to obtain a sensing result, such as sensing data.

[0259] In scenario 2, shown in Figure 2(b), one network device (e.g., base station 1) can serve as the sensing entity that sends the sensing signal, while another network device (e.g., base station 2) can serve as the sensing entity that receives the sensing signal. The transmitting end (Tx) and receiving end (Rx) of the sensing signal can be different network devices. The sensing signal sent by network device 1 reaches the target object. After being reflected by the target object, network device 2 can receive the sensing signal and process it to obtain a sensing result, such as sensing data.

[0260] The perception scenarios shown in (a) and (b) of FIG1 may be referred to as network device-based perception scenarios, or BS-to-BS perception scenarios.

[0261] In scenario 3, shown in Figure 2 (c), a network device (e.g., a base station) can serve as the sensing entity that transmits the sensing signal, and a terminal device (e.g., a mobile phone) can serve as the sensing entity that receives the sensing signal. The transmitting end (Tx) of the sensing signal can be the network device, and the receiving end (Rx) can be the terminal device. The sensing signal sent by the network device reaches the target object, is reflected by the target object, and is received by the terminal device. The terminal device then processes the sensing signal to obtain a sensing result, such as sensing data.

[0262] In scenario 4, shown in (d) of Figure 2, a terminal device (e.g., a mobile phone) can serve as the sensing entity that sends the sensing signal, and a network device (e.g., a base station) can serve as the sensing entity that receives the sensing signal. The sensing signal's transmitter (Tx) can be the terminal device, and the receiver (Rx) can be the network device. The sensing signal sent by the terminal device reaches the target object, reflects off the target object, and is then received by the network device. The network device then processes the sensing signal to obtain sensing results, such as sensing data.

[0263] The perception scenarios shown in (c) and (d) of Figure 2 can be called perception scenarios based on network devices and terminal devices, or, scenario 3 can be called BS-to-UE perception scenario, and scenario 4 can be called UE-to-BS perception scenario.

[0264] In scenario 5, shown in (e) of Figure 2 , a terminal device (e.g., a mobile phone) can act as both a sensing entity that sends and receives sensing signals. That is, the terminal device can simultaneously act as both a transmitter (Tx) and receiver (Rx) of sensing signals. The sensing signal sent by the terminal device reaches the target object, reflects off the target object, and is then received by the terminal device. The terminal device can then process the sensing signal to obtain a sensing result, such as sensing data.

[0265] In scenario 6 shown in (f) of Figure 2 , one terminal device (e.g., mobile phone 1) can serve as the sensing entity that sends the perception signal, while another terminal device (e.g., mobile phone 2) can serve as the sensing entity that receives the perception signal. The transmitter (Tx) and receiver (Rx) of the perception signal can be different terminal devices. The perception signal sent by terminal device 1 reaches the target object. After being reflected by the target object, the perception signal is received by terminal device 2, which then processes the perception signal to obtain a perception result, such as perception data.

[0266] The perception scenarios shown in (e) and (f) of Figure 2 can be called terminal device-based perception scenarios, or UE-to-UE perception scenarios.

[0267] The perception signal sent by the above-mentioned transmitting end can be called a first perception signal, and the perception signal received by the receiving end can be called a second perception signal. The second perception signal carries more information than the first perception signal. For example, the second perception signal can carry source information and environmental information.

[0268] Optionally, in embodiments of the present application, the network device may refer to the implementation of the RAN network element 110 described above. A terminal device may also be referred to as user equipment (UE). In some examples, the terminal device may be a wireless terminal. A wireless terminal may be a device that provides voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. For example, the terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a cellular phone, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a 5G or 6G mobile communication system or a terminal in a future evolution network, etc.

[0284] For example, the SSCF network element 120 may register the services it can provide with the NRF network element 140. The SDPF network element 130 may provide the NRF network element 140 with an interface for exposing data.

[0285] SEPP 150, shown in Figure 1, can ensure transmission security between different operator networks. Operator networks are also called public land mobile networks (PLMNs). SEPP 150 can be deployed in each operator's PLMN. For example, when cross-network signaling is transmitted between different PLMNs, it must be forwarded through SEPP 150. SEPP 150 can be responsible for the security protection of cross-network signaling and achieve network topology hiding. For example, SEPP 150 can replace the full qualified domain name (FQDN) of each network element in the signaling with an extended (telescopic) FQDN before forwarding it to other PLMNs. The interface between SEPPs can be called an N32 interface.

[0286] The AMF network element 160 may be responsible for managing user access and mobility management, including user access control, mobility management, security, and other functions.

[0287] The SMF network element 170 may be responsible for session management, including policy control, session management, user plane quality of service (QoS) control and other functions.

[0288] UPF network element 180 is responsible for processing user data packets, including functions such as flow control, data packet processing, and QoS policy enforcement. The interface that allows communication between different UPF network elements is called the N9 interface. For example, two different UPF network elements in the same operator's network can communicate via the N9 interface. For another example, a UPF network element in operator A's network can communicate directly with a UPF network element in operator B's network via the N9 interface.

[0289] In the embodiment of the present application, the communication system of each operator network can refer to that shown in Figure 1. The communication systems of different operator networks can be the same or different. For any operator network, the communication system shown in Figure 1 may include but is not limited to: narrowband Internet of Things (NB-IoT) system, global system for mobile communications (GSM) system, enhanced data rate for GSM evolution (EDGE) system, wide band code division multiple access (WCDMA) system, code division multiple access (CDMA) 2000 system, time division-synchronization code division multiple access (TD-SCDMA) system, long term evolution (LTE) system, 5G mobile communication system and next generation 5G mobile communication system, enhanced Mobile Broadband (eMBB), ultra-reliable low-latency communication (URLLC) and massive machine-type communications (mMTC), long-range Internet of Things (LTE), etc. range, LoRa) system or Internet of Vehicles system, or future 6G communication system or other evolved communication system, etc. This application does not limit the type of communication system.

[0290] Optionally, the communication system of each operator network may include more or fewer network elements than those shown in Figure 1. For example, it may also include a unified user / data management function (UDM) network element, a policy control function (PCF) network element, a sensing service subscriber management (SSSM) network element, a network exposure function (NEF) network element, etc.

[0291] Optionally, different network elements in the communication system of each operator's network can be combined or deployed separately. For example, the SSCF network element 120 and the SDPF network element 130 can be integrated together, deployed separately, or deployed together with other core network functional modules. After the control plane functions of the perception service and the data plane functions of the perception service are deployed independently, the number of control plane functional entities and data plane functional entities can be flexibly configured and adjusted based on resources and service conditions. Secondly, attacks on the data plane will not affect the control plane, which can improve the reliability and security of the perception service.

[0306] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of this application. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0307] For example, in the various embodiments described below in this application, the steps performed by each network element (such as an SSCF network element, an SDPF network element, a RAN network element, a UPF network element, etc.) can be specifically performed by a communication device that carries / deploys the network element, or a device (for example, a software module or chip) built into the communication device that carries / deploys the network element. The communication device can be a network device or a terminal device.

[0308] In the communication method provided in the embodiment of the present application, the first operator network can use the perception entity in the second operator network to obtain perception data. The first operator network and the second operator network are different. For example, the SSCF network element in the first operator network (hereinafter referred to as the first SSCF network element) can communicate with the SSCF network element in the second operator network (hereinafter referred to as the second SSCF network element) to request the perception entity in the second operator network to assist in obtaining perception data. The perception entity in the second operator network can be an access network network element (such as a base station) or a terminal device in the second operator network, hereinafter collectively referred to as the second RAN network element for description. The perception entity in the first operator network can be an access network network element (such as a base station) or a terminal device in the first operator network, hereinafter collectively referred to as the first RAN network element for description.

[0309] In this communication method, the first SSCF network element may send a request message to the second SSCF network element, requesting the second SSCF network element to provide a perception entity in the second operator's network to perform a perception task. The second SSCF network element may send a request message to the second RAN network element, requesting the second RAN network element to serve as the perception entity of the first operator's network, and send a response message to the first SSCF network element to notify the first SSCF network element that the second RAN network element can be provided as the perception entity.

[0310] For example, Figure 4 shows a flow chart of a communication method provided in an embodiment of the present application. As shown in Figure 4, the communication method may include S401-S404.

[0311] S401. The first SSCF network element sends a request message 1 to the second SSCF network element. The request message 1 is used to indicate a request for the second operator network to provide a RAN network element as a second perception entity for the first operator network.

[0312] Correspondingly, the second SSCF network element receives the request message 1.

[0313] Exemplarily, the first SSCF network element belongs to the first operator network. The data requester of the perception data, such as a third-party entity in the first operator network or a network function (NF) network element within the network, can request the first SSCF network element to perform perception task orchestration to obtain the perception data. The meanings of the third-party entity and the NF network element can be found in the aforementioned embodiments and will not be repeated here. For example, the data requester can request the first SSCF network element to obtain the perception data of the perception service 1. The first SSCF network element can select a sending perception entity and a receiving perception entity to perform the perception task to obtain the perception data. For example, the first SSCF network element can send a control message (or perception control message) to the sending perception entity and the receiving perception entity, respectively, instructing the sending entity to send a perception signal, and instructing the receiving perception entity to receive a perception signal. The perception signal received by the receiving perception entity carries the perception data.

[0314] In an embodiment of the present application, a first SSCF network element may send a request message 1 to a second SSCF network element, requesting the second operator network to provide a RAN network element to the first operator network as a perception entity to perform perception tasks. The perception entity provided by the second operator network may be referred to as a second perception entity. The perception entity in the first operator network may be referred to as a first perception entity.

[0315] In one possible scenario, the first SSCF network element may request the second operator network to provide a receiving perception entity. The second perception entity may serve as the receiving perception entity to receive perception signals and obtain perception data based on the received perception signals. When the second perception entity serves as the receiving perception entity, the sending perception entity may be the first perception entity in the first operator network. That is, the first perception entity is used to send perception signals, and the second perception entity is used to receive perception signals. The second perception entity may include one or more.

[0316] In another possible scenario, the first SSCF network element may request the second operator network to provide a sending perception entity, and the second perception entity may serve as the sending perception entity to send perception signals. When the second perception entity serves as the sending perception entity, the receiving perception entity may be the first perception entity in the first operator network. That is, the second perception entity is used to send perception signals, and the first perception entity is used to receive perception signals. The first perception entity may obtain perception data based on the received perception signals. The second perception entity may also include one or more second perception entities.

[0317] In another possible scenario, the first SSCF network element may request the second operator network to provide a sending perception entity and a perception entity. The second perception entity may function as a sending perception entity to send perception signals and simultaneously function as a receiving perception entity to receive perception signals, i.e., the second perception entity may transmit and receive perception signals autonomously. Alternatively, some second perception entities may function as sending perception entities to send perception signals, while others may function as receiving perception entities to receive perception signals. The second perception entity may also include one or more second perception entities.

[0318] Exemplarily, the request message 1 may include at least one of the following information: a sensing service identifier, a sensing area, sensing data requirement information, and sensing entity requirement information.

[0319] The sensing service is used to indicate a sensing service, for example, it may be an identifier of sensing service 1. The sensing service identifier may also be called a sensing identifier.

[0320] The sensing service area is used to indicate the sensing range of the second sensing entity. The second SSCF network element can determine the second sensing entity based on the sensing area, for example, selecting a sensing entity whose signal can cover the sensing area as the second sensing entity. The sensing service area can also be called a service zone.

[0321] The sensing data requirement information is used to indicate the sensing data requirements of the sensing service, for example, the sensing data requirements may be accuracy requirements, data quality requirements, etc. The second SSCF network element may also select a suitable sensing entity as the second sensing entity according to the sensing data requirement information.

[0322] The SE requirement information is used to indicate the SE type of the second sensing entity, where the SE type includes a sending sensing entity and / or a receiving sensing entity. The second SSCF network element may select to provide the sending sensing entity and / or the receiving sensing entity as the second sensing entity based on the SE requirement information. For details, please refer to the different implementation scenarios of the second sensing entity described above.

[0323] Optionally, the sensing entity requirement information may also be used to indicate the number of sensing entities that need to be provided. Alternatively, the second SSCF network element may determine the number of second sensing entities based on the sensing data requirement information, which is not limited here.

[0324] After receiving the request message 1, the second SSCF network element can select and provide a second RAN network element as the second perception entity of the first operator network based on the information contained in the request message 1, and execute the following S402. As mentioned above, the second RAN network element includes one or more, and this article only uses one as an example for description.

[0325] Exemplarily, the second SSCF network element may select a second perception entity based on the perception capability information of each perception entity in the second operator network. For example, request message 1 indicates that a receiving perception entity needs to be provided as the second perception entity, and the perception service is the first perception service of area 1. If the current latitude and longitude information of perception entity a in the second operator network is within the range of area 1, and the role identifier of perception entity a is a receiving perception entity, the second SSCF network element may select perception entity a as the second perception entity. Perception entity a may be referred to as a second RAN network element.

[0327] Among them, the device identifier is used to uniquely identify the perception entity. For example, if the first perception entity is a terminal device, the device identifier can be an international mobile equipment identity (IMEI), a user permanent identifier (SUPI), a user hidden identifier (SUCI), a media access control (MAC) address, etc. For another example, if the first perception entity is a network device, the device identifier can be a cell identifier and / or a tracking area identity (TAI), etc., and the cell identifier can be, for example, a physical cell identifier (PCI).

[0328] The role identifier is used to indicate that the sensing entity is a sending sensing entity and / or a receiving sensing entity.

[0329] The device type is used to indicate whether the sensing entity is a network device or a terminal device. Optionally, if it is a network device, the device type can also indicate whether the network device is a base station, CU, or DU. If it is a terminal device, the device type can also indicate whether the terminal device is a UE, IoT device, flight device, or VR device.

[0330] The geographic location information may be used to indicate one or more of the following: the current geographic location of the sensing entity, the geographic location range that the sensing entity can sense, and the geographic location, such as latitude and longitude information, global positioning system (GPS) location information, etc.

[0332] Among them, the L1 perception processing capability is used to perceive raw data. Raw data refers to basic information of the perception signal, such as amplitude, phase, and whether the perception signal is an I-channel signal or a Q-channel signal, among other information.

[0333] L2 perception processing capability is used to perceive measurement data. Measurement data refers to data obtained by processing raw data and is used to characterize the measurement dimension. It may include but is not limited to one or more of the following information: sampling point latency, perception signal reception angle, perception signal strength, Doppler (i.e., perception signal frequency offset), target object location, target object speed, etc.; sampling points refer to signal values ​​at specific moments or locations selected during the discretization of continuous signals during signal processing.

The perception results can include but are not limited to one or more of the following information: the distance between the perception entity and the target object, the speed of the target object, the position of the target object, the angle between the perception entity and the target object, the moving path of the target object, the breathing rate of the target object, the heartbeat of the target object, etc.

[0335] The supported perception service types are used to indicate the types of perception services that the perception entity can provide, and may include but are not limited to one or more of the following types: environment type, monitoring type, imaging type, positioning type, etc. The environment type may include but are not limited to one or more of the following: ambient temperature, ambient humidity, air quality, weather conditions, crowd density, traffic density, air pressure, etc. The monitoring type may include but are not limited to one or more of the following: mobile monitoring, intrusion monitoring, fall monitoring, health monitoring, etc. Mobile monitoring may include but are not limited to one or more of the following: distance monitoring, location monitoring, mobile speed monitoring, mobile path monitoring, etc. Health monitoring may include but are not limited to one or more of the following: respiratory rate, heartbeat, etc. The imaging type may include but are not limited to one or more of the following: medical imaging, 3D map imaging, 3D map construction, building imaging, body temperature imaging, etc.

[0336] This application does not limit the specific method in which the second SSCF network element selects the second perception entity.

[0337] Optionally, the information contained in the request message 1 described above may also be sent to the SSCF via other messages or other methods, which is not limited in this application.

[0338] Exemplarily, the request message 1 may be an “Nsscf_SensingService_Request” interface message.

[0339] S402. The second SSCF network element sends a request message 2 to the second RAN network element. The request message 2 is used to instruct the second RAN network element to serve as a second perception entity of the first operator network.

[0340] Correspondingly, the second RAN network element receives the request message 2 .

[0341] As described above, the second RAN network element is the second perception entity selected by the second SSCF network element.

[0342] Exemplarily, the request message 2 may also include at least one of the following information: a sensing service identifier, a sensing area, and sensing data requirement information. The second RAN network element may perform the sensing task according to the aforementioned information included in the request message 2, and details are omitted for brevity.

[0343] Optionally, in this embodiment of the present application, the request message 2 may further include role type information, also known as perception role information or perception entity type information. The role type information is used to indicate that the second RAN network element needs to serve as a sending perception entity and / or a receiving perception entity. For details, please refer to the above description.

[0344] Exemplarily, the request message 2 may be an “Ns_Sensing_Request” interface message.

[0345] S403. The second RAN network element sends a response message 2 to the second SSCF function network element.

[0346] Optionally, the response message 2 is used to indicate confirmation as the second perception entity of the first operator network.

[0347] Correspondingly, the second SSCF network element receives response message 2.

[0348] Exemplarily, the above-mentioned response message 2 may be an “Ns_Sensing_Response” interface message.

[0349] S404. The second SSCF network element sends a response message 1 to the first SSCF network element.

[0350] Optionally, the response message 1 may be used to indicate providing a second RAN network element as a second perception entity of the first operator network.

[0351] Correspondingly, the first SSCF network element receives the response message 1.

[0352] Exemplarily, the above-mentioned response message 1 may be an “Nsscf_SensingService_Response” interface message.

[0353] Through the process shown in Figure 4 above, a connection can be established between the second RAN network element in the second operator network and the first operator network (or the first SSCF network element), so that the first operator network can use the second RAN network element in the second operator network as the second perception entity to obtain perception data.

[0354] It should be understood that in the scenario where the second perception entity (second RAN network element) serves as the receiving perception entity, the first perception entity is used to send the perception signal, and the second perception entity is used to receive the perception signal, the first SSCF network element may further send a request message (or control message) to the first RAN network element in the first operator's network, requesting the first RAN network element to serve as the sending perception entity. The first RAN network element may include one or more.

[0355] In the scenario where the second perception entity (second RAN network element) serves as a sending perception entity, the second perception entity is used to send perception signals, and the first perception entity is used to receive perception signals, the first SSCF network element may further send a request message to a first RAN network element in the first operator's network, requesting the first RAN network element to serve as a receiving perception entity. The first RAN network element may include one or more.

[0356] For the aforementioned scenarios where the second sensing entity acts as a sending entity and the sensing entity both sends and receives data, as well as scenarios where some second sensing entities act as sending sensing entities and some act as receiving sensing entities, the first SSCF network element may also send a request message to the first RAN network element in the first operator's network, requesting that the first RAN network element act as the first sensing entity. In this case, the sensing entity type for the first RAN network element is similar to that for the second RAN network element: the first RAN network element may act as both sending and receiving data, or some first RAN network elements may act as sending sensing entities and some as receiving sensing entities. This will not be further described. The first RAN network element may include one or more.

[0357] For example, Figure 5 shows another flow chart of a communication method provided in an embodiment of the present application. As shown in Figure 5, the communication method may include S501-S506.

[0371] Optionally, in this embodiment of the present application, the request message 3 may further include role type information, also known as perception role information or perception entity type information.

[0374] Optionally, the response message 3 is used to indicate confirmation that the first RAN network element serves as the first perception entity.

[0375] Correspondingly, the first SSCF network element receives response message 3.

[0376] Exemplarily, the above-mentioned response message 3 may be an “Ns_Sensing_Response” interface message.

[0377] Optionally, S505 - S506 may also be executed before S501 - S504 , and there is no restriction on the execution order.

[0378] In one possible design, in a scenario where the second sensing entity (second RAN network element) serves as a receiving sensing entity, the first sensing entity is configured to send sensing signals, and the second sensing entity is configured to receive sensing signals, the first SSCF network element may further obtain spectrum resources (e.g., frequency information) used by the first RAN network element to send the sensing signals, or referred to as spectrum resources carrying the sensing signals. The first SSCF network element may send the spectrum resources carrying the sensing signals to the second SSCF network element, and the second SSCF network element may send the spectrum resources carrying the sensing signals to the second RAN network element, so that the second RAN network element can receive the sensing signals based on the spectrum resources carrying the sensing signals.

[0384] Correspondingly, the first SSCF network element receives response message 3.

[0385] S601-S602 may refer to the above S505-S506, the difference being that the response message 3 carries or indicates the spectrum resources for carrying the perception signal, which will not be described in detail.

[0395] It should be noted that, in the process shown in FIG6 , S601 - S602 need to be executed before S603 - S606 so that the first SSCF network element can obtain the spectrum resources carrying the perception signal to send the spectrum resources carrying the perception signal to the second SSCF network element.

[0396] In the process shown in Figure 6, the first SSCF network element can obtain the spectrum resources carrying the perception signal through the response message 3 sent by the first RAN network element, and send it to the second SSCF network element.

[0415] Optionally, for the above-mentioned scenarios where the second sensing entity acts as a sending entity and the sensing entity transmits and receives signals independently, the second RAN network element itself can know the spectrum resources that carry the sensing signals. For scenarios where some second sensing entities act as sending sensing entities and some second sensing entities act as receiving sensing entities, different RAN network elements within the second operator network can synchronize the spectrum resources that carry the sensing signals. This application does not limit the method for synchronizing the spectrum resources.

After receiving the sensing request message 2, the second SSCF network element may send a sensing request message 3 to the second RAN network element, instructing the second RAN network element to perform sensing. This differs from the process shown in FIG9 in that, in this case, the second RAN network element receives the sensing signal (either sending and receiving it independently or sending and receiving it independently) and obtains sensing data based on the sensing signal. The sensing data obtained by the second RAN network element may be transmitted to the first SDPF network element, thereby allowing the first SDPF network element to obtain the sensing data obtained by the second RAN network element.

[0471] As described above, the communication method provided by the embodiments of the present application can enable different operator networks to share a perception entity to obtain perception data. For example, the communication method can enable a first operator network to use a second RAN network element in a second operator network as a perception entity to obtain perception data.

[0472] Optionally, in the embodiments of the present application, in Figures 4 to 9 above, the request message 3 sent by the first SSCF network element to the first RAN network element may be referred to as the fourth request message, and the response message 3 sent by the first RAN network element to the first SSCF network element may be referred to as the fourth response message.

The perception request message 1 sent by the first SSCF network element to the first RAN network element may be referred to as the first perception request message, and the perception response message 1 sent by the first RAN network element to the first SSCF network element may be referred to as the first perception response message.

[0473] The perception request message 2 sent by the first SSCF network element to the second SSCF network element may be referred to as a second perception request message, and the perception response message 2 sent by the second SSCF network element to the first SSCF network element may be referred to as a second perception response message. The perception request message 3 sent by the second SSCF network element to the second RAN network element may be referred to as a third perception request message, and the perception response message 3 sent by the second RAN network element to the second SSCF network element may be referred to as a third perception response message.

[0474] It is understood that in the embodiment of the present application, the first SDPF network element in the first operator network can obtain perception data, and the perception data obtained by the first SDPF network element can include two types: one type is perception data obtained by the first RAN network element (first perception entity) receiving a perception signal, and the other type is perception data obtained by the second RAN network element (second perception entity) receiving a perception signal. After obtaining the perception data, the first SDPF network element can process the perception data, for example, by fusing, performing L2 perception processing, and / or L3 perception processing.

[0475] In the embodiments of the present application, the perception data obtained by the second RAN network element from receiving the perception signal may be referred to as first perception data, and the perception data obtained by the first RAN network element from receiving the perception signal may be referred to as second perception data. The second perception data may be obtained by the first RAN network element based on the perception signal sent by the second RAN network element. Different implementation scenarios for the second RAN network element receiving the perception signal can be described in the aforementioned embodiments and will not be further elaborated.

[0476] The second perception data does not need to be transmitted across networks. For example, the first RAN network element can obtain the second perception data based on the received perception signal and send the second perception data to the first SDPF network element. Accordingly, the first SDPF network element can receive the second perception data.

[0477] In a possible design, the second perception data sent by the first RAN network element to the first SDPF network element may be original perception data obtained by the first RAN network element based on measurements of received perception signals.

[0478] In another possible design, the second perception data sent by the first RAN network element to the first SDPF network element may be perception data processed by the first RAN network element. For example, the first RAN network element may also have the capability to process raw perception data. After obtaining the raw perception data based on received perception signal measurements, the first RAN network element may process the raw perception data, such as performing L1 perception processing and / or L2 perception processing, to obtain processed perception data.

[0479] This application does not limit the second perception data to being original perception data or processed perception data.

[0480] Regarding the first perception data, after obtaining the first perception data, the second RAN network element needs to transmit the first perception data to the first SDPF network element via cross-network transmission. Similar to the second perception data, the first perception data can also be raw perception data obtained by the second RAN network element, or perception data processed by the second RAN network element.

[0481] In one possible design, the second RAN network element may transmit the first perception data to the first SDPF network element via the second SDPF network element, thereby achieving cross-network transmission of the first perception data. The second SDPF network element may be a second operator network. For example, the communication method may further include: the second RAN network element sending the first perception data to the second SDPF network element. In response, the second SDPF network element receives the first perception data. The second SDPF network element sends the first perception data to the first SDPF network element. In response, the first SDPF network element receives the first perception data.

[0482] Optionally, a first perception bearer may be established between the first SDPF network element and the second SDPF network element, and the first perception data may be transmitted via the first perception bearer. In other words, the first SDPF network element may send the first perception data to the second SDPF network element via the first perception bearer.

[0483] Among them, the first perception bearer can be understood as a perception shared data transmission channel, which is used for the second SDPF network element to send perception data to the first SDPF network element. The first perception bearer can be initiated and established by the first operator network side, and can also be initiated and established by the second operator network side. The first perception bearer can be pre-established, or it can be established when the first SSCF network element requests the second RAN network element as a receiving perception entity. For example, it can be established in the process shown in Figure 6 or Figure 8 above. The following takes the second SSCF network element in the second operator network initiating the establishment of the first perception bearer as an example to introduce the establishment process of the first perception bearer.

[0484] For example, Figure 10 shows a schematic diagram of a process for establishing a first awareness bearer according to an embodiment of the present application. As shown in Figure 10 , the process for establishing a first awareness bearer may include S1001-S1010.

[0486] Correspondingly, the second SDPF network element receives the request message 4 .

[0490] Correspondingly, the second SSCF network element receives the response message 4.

[0491] Exemplarily, the response message 4 may be a “SensingBearer_Establishment_Response” interface message.

[0493] S1003. The second SSCF network element sends a request message 5 to the first SSCF network element. The request message 5 is used to indicate a request to establish a first perception bearer.

[0494] Correspondingly, the first SSCF network element receives the request message 5 .

The communication information of the second SDPF network element may be understood as an interface of the second SDPF network element, which may be used by other network elements (such as the first SDPF network element) to establish a data transmission channel with the second SDPF network element, i.e., a first perception bearer.

[0496] Exemplarily, the request message 5 may be an “Nsscf_SensingBearer_Create_Request” interface message.

[0582] In some possible implementations, in the above-described embodiment of transmitting the first perception data across the network via the first UPF network element and the second UPF network element, the message carrying the first perception data indicates or carries first indication information, and the first indication information is used to indicate that the perception data needs to be transmitted to the first SDPF network element. For example, a data packet of the first perception data may indicate or carry the first indication information. After receiving the first perception data, the first UPF network element may know, based on the first indication information, that the first perception data needs to be transmitted to the first SDPF network element.

[0583] Optionally, the first indication information may be an agreed IP address, such as a fixed or special IP address. Before sending the first perception data, the second RAN network element may encapsulate the first perception data, using the agreed IP address as the destination address. The encapsulated packet of the first perception data is transmitted to the first UPF network element via the process shown in FIG11 . Alternatively, the first UPF network element may parse the encapsulated packet of the first perception data to obtain the agreed IP address. The agreed IP address may instruct the first UPF network element to send the first perception data to the first SDPF network element.

[0584] The agreed IP address can reduce the security exposure of the first SDPF network element and improve security.

[0585] Optionally, the first indication information (e.g., the agreed IP address) may be agreed upon by the first SSCF network element and the second SSCF network element. For example, the first indication information may be included in the request message 1 sent by the first SSCF network element to the second SSCF network element in the aforementioned embodiment, and then transmitted to the second SMF via the SBI. The second SMF may send the first indication information to the second UPF network element in the N4 session establishment request message 1 shown in FIG12 above. The first SMF may send the first indication information to the first UPF network element in the N4 session establishment request message 2 shown in FIG12 above. The first indication information may be included in the request message 2 sent by the second SSCF network element to the second RAN network element in the aforementioned embodiment, so as to be sent to the second RAN network element.

[0586] Alternatively, the first indication information (e.g., agreed IP) may also be agreed upon when establishing the session. For example, the second RAN network element may carry the first indication information when sending a session establishment request to the second AMF network element. After that, the second AMF network element sends the first indication information to the second SMF network element, and the second SMF network element sends the first indication information to the first SMF network element. The second SMF network element and the first SMF network element may send the first indication information to the second UPF network element and the first UPF network element respectively through the above-mentioned N4 session establishment request message 1 and N4 session establishment request message 2.

[0587] Optionally, the first indication information may also be other fields, or, in some other possible implementation methods, other methods may be used to indicate to the first UPF that the first perception data needs to be transmitted to the first SDPF network element. This application does not impose any restrictions on this.

[0588] Optionally, the second RAN network element may also send the first perception data to the second SDPF network element, and the second SDPF network element may send the first perception data to the second UPF network element, so as to transmit the first perception data to the first SDPF network element through the second UPF network element and the first UPF network element. The implementation process is similar to that shown in Figures 11 and 12 above and will not be repeated here.

[0589] It should be understood that in an embodiment of the present application, the first SSCF network element needs to first obtain relevant information of the second SSCF network element, such as FQDN, before it can send the above-mentioned request message 1 to the second SSCF network element, requesting the second operator network to provide a RAN network element for the first operator network as a second perception entity.

[0590] In one possible design, the first SSCF network element can send a cross-domain perception assistance request to the first NRF network element, requesting to obtain the full address domain name information (such as FQDN) of the SSCF network element in the second operator network. The first NRF network element can send a cross-domain perception assistance request to the second NRF network element. After receiving the cross-domain perception assistance request, the second NRF network element can return the full address domain name information of the second SSCF network element to the first NRF network element. The first NRF network element can send the full address domain name information of the second SSCF network element to the first SSCF network element. The first NRF network element belongs to the first operator network, and the second NRF network element belongs to the second operator network.

[0602] Correspondingly, the first SSCF network element receives the cross-domain perception assistance response message 1.

[0603] Exemplarily, the cross-domain awareness assistance response message 1 may be an “Nnrf_NFDiscovery_Response” interface message.

[0604] Through the process shown in FIG13 , the first SSCF network element can obtain the full address domain name information of the second SSCF network element.

[0607] Optionally, in embodiments of the present application, in inter-network communications between different carrier networks, inter-network transmission of signaling needs to pass through the SEPP.

For example, each signaling inter-network transmission between the first carrier network and the second carrier network shown in Figures 4 to 10, and Figures 12 and 13, can be forwarded through the SEPPs of the first carrier network and the second carrier network.

[0608] For example, taking the process of the first SSCF network element obtaining the full address domain name information of the second SSCF network element as shown in Figure 13 as an example, Figure 14 shows another flow chart of the communication method provided in an embodiment of the present application. As shown in Figure 14, the communication method may include S1401-S1408.

[0610] Correspondingly, the first NRF network element receives the cross-domain awareness assistance request message 1.

[0611] S1402. The first NRF network element sends a cross-domain awareness assistance request message 2 to the first SEPP. The cross-domain awareness assistance request message 2 is used to indicate a request to obtain the full address domain name information of the second SSCF network element.

[0612] Accordingly, the first SEPP receives the cross-domain awareness assistance request message 2. The first SEPP belongs to the first operator network.

[0614] Exemplarily, the information carried by the cross-domain awareness assistance request message 3 includes the information carried by the cross-domain awareness assistance request message 2. For example, the cross-domain awareness assistance request message 1, the cross-domain awareness assistance request message 2, and the cross-domain awareness assistance request message 3 can all carry a target operator network list (target-plmn-list) and awareness area information.

[0615] Correspondingly, the second SEPP receives the cross-domain awareness assistance request message 3.

[0616] The second SEPP may determine the second NRF network element according to the sensing area information.

[0617] S1404. The second SEPP sends a cross-domain awareness assistance request message 4 to the second NRF network element. The cross-domain awareness assistance request message 4 is used to indicate a request to obtain the full address domain name information of the second SSCF network element.

[0627] Optionally, in an embodiment of the present application, the first SSCF network element may send the above-mentioned fifth request message or the seventh request message to the second SSCF network element when the available perception entity resources of the first operator network are insufficient.

[0628] For example, the first SSCF network element selects a perception entity within area 1 for perception based on the perception service, such as environmental perception, but finds that the perception entity is missing or the number of perception entities is insufficient (for example, the perception entity within its own network may be faulty). The first SSCF network element can send a request message to the second SSCF network element, requesting the second operator network to provide a second RAN network element as a perception entity to help obtain perception data.

[0629] Optionally, in an embodiment of the present application, when the RAN network element within the operator network sends perception data to the SDPF network element, for example, the first RAN network element sends second perception data to the first SDPF network element, and the second RAN network element sends first perception data to the second SDPF network element, the RAN network element can publish the perception data to the data communication proxy (DCP) network element, and the SDPF network element can subscribe to the DCP network element to obtain the perception data.

[0631] The DCP can be deployed as a standalone network element in a 3GPP network, or it can be integrated with network elements or devices in a 3GPP network. Alternatively, the DCP can be deployed in an access network or in a core network. This application does not limit the implementation of the DCP network element.

SDPF network elements can act as data consumers to subscribe to and extract data from DCP network elements, such as obtaining perception data using a topic subscribe method.

For example, each message can utilize the existing interface between the interacting network elements or define a new interface when implemented.

In addition, it can also be stored in a memory in the form of a program, and called by a certain processing element of the device to execute the function of the unit. In addition, all or part of these units can be integrated together, or they can be implemented independently.

The SOC chip is used to implement the corresponding method. The chip can integrate at least one processing element and a storage element, and the processing element calls the program stored in the storage element to implement the corresponding method; or, the chip can integrate at least one integrated circuit to implement the corresponding method; or, the above implementation methods can be combined, with the functions of some units being implemented by the processing element calling the program, and the functions of some units being implemented by the integrated circuit.
