Description

Communication method, device, equipment, storage medium, chip, product and program

[0001] The embodiments of the present application relate to the field of mobile communication technology, and specifically to a communication method, apparatus, device, storage medium, chip, product and program.

[0002] Wireless sensing refers to the perception of environmental information through sensing signals. Environmental information may include the distribution, size, quantity, temperature of objects in the environment, human movements and behaviors, human breathing rate or heart rate, etc.

[0003] In wireless sensing, the sending unit can send a sensing signal to the sensed object, and the receiving unit receives the sensing signal reflected and / or scattered and / or multipath transmitted by the environment. The receiving unit can discover the characteristics of the environment through signal processing, and then identify people or objects in the environment, detect temperature, detect movement, breathing rate or heart rate, etc.

[0004] However, the related art needs to arrange a sending unit and a receiving unit, and can only determine the sensing information of the sensed object between the sending unit and the receiving unit, resulting in a narrow application scope of the wireless sensing in the related art.

[0089] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0090] FIG2 is a schematic diagram of a system architecture based on a reference point presentation method provided by an embodiment of the present application. As shown in FIG2, the reference point presentation method can show that there can be interaction between corresponding network function (NF) services. Network functions include, for example: Access and Mobility Management Function (AMF) 201, Session Management Function (SMF) 202, Policy Control Function (PCF) 203, Application Function (AF) 204, User Plane Function (UPF) 205, Network Slice Selection Function (NSSF) 206, Authentication Server Function (AUSF) 207 and Unified Data Management (UDM) 208, etc. The system may also include: UE 209, Radio Access Network (RAN) or Access Node (AN) 210, Data Network (DN) 211.

[0091] Figure 2 shows the following reference points: N1 (between UE 209 and AMF 201), N2 (between RAN 210 and AMF 201), N3 (between RAN 210 and UPF 205), N4 (between SMF 202 and UPF 205), N5 (between PCF 203 and AF 204), N6 (between UPF 205 and DN 211), N7 (between SMF202 and PCF 203), N8 (between UDM 208 and AMF 201), N9 (between two UPFs 205), N10 (between UDM 208 and SMF202), N11 (between AMF 201 and SMF 202), N12 (between AUSF 207 and AMF 201), N13 (between AUSF 207 and UDM 208), N14 (between two AMF 201), N15 (between PCF 203 and AMF 201 in a non-roaming scenario, or between PCF 203 and the visited network and AMF 201 in a roaming scenario), N16 (between two SMFs; not shown) and N22 (between AMF 201 and NSSF 206).

[0092] The following is an explanation of SMF, PCF and AF:

[0093] SMF: includes session establishment, modification and release, tunnel maintenance between UPF and AN nodes, terminal Internet Protocol (IP) address allocation and management, selection and control of UPF functions, billing data collection and billing interface support, etc.

[0094] PCF: Supports a unified policy framework to manage network behavior and provides operator network control policies to other network elements and terminals.

[0095] AF: It can be an application within the operator, such as IP Multimedia Subsystem (IMS), or a third-party service, such as web services, videos or games. If it is an AF within the operator, and it is in a trusted domain with other NFs, it can directly interact with other NFs; if the AF is not in a trusted domain, it needs the network exposure function (NEF) to access other NFs.

[0096] The UE establishes an access layer connection with the AN through the Uu port, exchanges access layer messages and wireless data transmission. The UE establishes a non-access layer (NAS) connection with the AMF through the N1 port, and exchanges NAS messages. AMF is the mobility management function in the core network, and SMF is the session management function in the core network. In addition to mobility management of the UE, AMF is also responsible for forwarding session management related messages between the UE and SMF. PCF is a policy management function in the core network, responsible for formulating policies related to UE mobility management, session management, billing, etc. UPF is a user plane function in the core network, which transmits data with the external data network through the N6 interface and transmits data with the AN through the N3 interface.

[0097] The networks in related technologies, such as 5G and other cellular networks, are only used for communication. However, the radio electromagnetic wave signals used by cellular networks can not only be used for wireless data transmission and communication purposes, but also have environmental perception capabilities, such as user motion or gesture recognition, breathing monitoring, terminal movement speed measurement, environmental imaging, weather monitoring, etc. Therefore, cellular networks can be considered not only for communication and data transmission, but also for the acquisition of perception information.

[0098] Beyond 5th Generation (B5G) or later networks may support sensing capabilities by adding sensing network elements (Sensing Function) and corresponding processes to support sensing functions in the 3rd Generation Partnership Project (3GPP) network. Optionally, the sensing network element may include a sensing control network element.

[0114] In the embodiment corresponding to Figure 3, when the application (corresponding to the above-mentioned AF) sends a perception request for the target UE / object (corresponding to the above-mentioned perceived object) to the core network of the 3GPP network, the core network selects an access network device or a terminal device through a perception control network element or an access and mobility management function (AMF), and triggers the access network device or the terminal device to enable the capability of perception-related wireless measurements, so that the access network device or the terminal device starts the measurement of perception information and generates perception results.

[0115] The main wireless sensing scenarios of synaesthesia integration include at least one of the following:

[0116] 1) Access network device echo sensing link: The access network device sends a sensing signal and receives an echo signal;

[0117] 2) Perception link between access network devices: Access network device B receives the perception signal sent by access network device A;

[0118] 3) Air interface uplink perception link: The access network device receives the perception signal sent by the terminal device;

[0119] 4) Air interface downlink perception link: The terminal device receives the perception signal sent by the access network device;

[0120] 5) Terminal device echo sensing link: The terminal device sends a sensing signal and receives an echo signal;

[0121] 6) Perception link between terminal devices: Terminal device B receives the perception signal sent by terminal device A.

[0122] The communication method in the embodiment of the present application can be applied to any one or more scenarios listed in the above-mentioned synaesthesia integration. In the B5G communication perception integration, it is possible to consider the air interface signal specified in the multiplexing protocol to perform perception behavior.

[0123] The goal of wireless sensing is to obtain a series of sensing results such as the speed, distance, moving direction, shape, etc. of the sensed object.

[0124] In the embodiment of the present application, the operation process of the perception service sent by A and received by B is mainly considered, A can be a terminal device or an access network device, and B can be a terminal device or an access network device. Optionally, A can be a sending unit and B can be a receiving unit.

[0125] However, if the sensed object is in a moving state, a single receiving unit for receiving the sensing signal cannot continuously determine the information of the sensed object, thereby failing to achieve continuous detection of the sensed object.

[0126] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0127] Since the sensed object may be moving when the wireless sensing service is actually applied, when the distance between the sensed object and the sensing signal sending unit increases, or when the distance between the sensed object and the receiving unit that receives the sensing signal increases, or when the total distance of the distance between the sensed object and the sensing signal sending unit plus the distance between the sensed object and the receiving unit that receives the sensing signal increases, the quality of the received signal of the receiving unit will decrease, so the receiving unit and / or the sending unit can be replaced, or one or more receiving units can be switched to another one or more receiving units, and / or one or more sending units can be switched to another one or more sending units, so that the wireless sensing service can be continuous, thereby realizing continuous detection of the sensed object.

As shown in FIG4 , the sensed object 401 leaves the coverage of the sending unit 1, the signal quality of the sensed received sensed signals of UE1-3 all decreases, and the sensed received signal quality of UE4-6 increases, so it can be considered that the sending unit and the receiving unit should be switched. Optionally, a target sending unit (e.g., sending unit 2) that is closer is selected based on the initial position + tracking result of the sensed object 401. For example, the network or the sending unit 1 can determine the sending unit 2 based on the current position of the sensed object 401.
