[0062] Refer to Figure 1, which is a schematic diagram of a first communication architecture of an AIoT system provided by an embodiment of the present disclosure.

[0063] The device 11 may be an electronic device that provides data or voice connectivity. For example, the device 11 may be an electronic tag, such as a Radio Frequency Identification (RFID) tag, or may be a passive tag.

[0064] It should be noted that the device 11 is not limited to an electronic tag, but may also be a user equipment (UE), a subscriber unit (Subscriber Unit), a mobile station (Mobile Station), a station (Station), a terminal (Terminal), etc.

[0065] In the embodiments of the present disclosure, device 11 can communicate with a reader / writer of the AIoT system and can communicate with other communication devices through the AIoT system, such as household appliances in a smart home, power meters, voltage monitoring instruments, environmental monitoring instruments in a smart grid, and video monitoring instruments in a smart security network. In other words, device 11 can communicate with a reader / writer, or device 11 can communicate with core network devices through a reader / writer. Multiple devices 11 can also communicate with each other. Device 11 can be static or mobile, and this is not limited in the embodiments of the present disclosure.

[0066] In some embodiments, the device 11 may be an ambient-powered IoT device (AIoT device). The device 11 may be a mobile terminal, a fixed terminal, or the like in various fields that can utilize ambient energy. In the embodiments disclosed herein, the specific form of the terminal device is not limited. For the device 11 utilizing solar energy, normal communication can be performed using solar energy during sunny days, while on rainy days or at night, the communication capability may be limited and the device may be in a dormant state where no signaling / data is sent or received. Similar situations also exist for ambient-powered IoT devices utilizing other ambient energy sources.

[0067] The reader can be used to send and receive AIoT instructions to device 11, and can execute AIoT requirements (also known as AIoT services), such as inventory commands, read commands, write commands, disable commands, etc.

[0068] In the embodiment of the present disclosure, the reader / writer may be a UE reader / writer 12. For example, the UE reader / writer 12 may be integrated into or externally connected to the UE.

[0069] It should be noted that UE may include smart phones, smart wearable devices, smart speakers, smart tablets, wireless modems, wireless local loop (WLL) stations, personal digital assistants (PDAs), customer premises equipment (CPEs), etc.

[0070] The base station 13 may be a NG-RAN (Radio Access Network) device in LTE; the base station 13 may also be a base station in a future evolved Public Land Mobile Network (PLMN), a Broadband Network Gateway (BNG), an aggregation switch, or a non-3rd Generation Partnership Project (3GPP) access device. Optionally, the base station 13 in the embodiment of the present disclosure may include various forms of base stations, such as a macro base station, a micro base station (also known as a small base station), a relay station, an access point, a 5G base station or a future base station, a satellite, a Transmitting and Receiving Point (TRP), a Transmitting Point (TP), a mobile switching center, and a device-to-device (D2D), a machine-to-machine (M2M), the Internet of Things (IoT), a vehicle-to-everything (V2X), or other devices that perform base station functions in communications, etc., and the embodiment of the present disclosure does not specifically limit this.

[0071] The Access and Mobility Management Function (AMF) 14, the Unified Data Management (UDM) 16 and the Application Function (AF) 17 may be referred to as core network devices.

[0072] The AMF 14 is the termination point for non-access stratum (NAS) signaling and is primarily responsible for user access authentication and mobility management. Terminal devices and the AMF can communicate via N1 NAS messages, and communication messages between the terminal device and the AMF can also be relayed via RAN N2 messages. The RAN and the AMF communicate via N2 messages.

[0073] The UDM 16 can be used to manage user contract information and complete user authentication and authorization.

[0074] AF17 can be used to provide instructions for AIoT services and is also called an application server.

[0075] It should be noted that in the embodiments of the present disclosure, the core network device may further include one or more of a session management function (SMF), a network exposure function (NEF), a user plane function (UPF), and a policy control function (PCF). For more information about the above-mentioned AMF, UDM, AF, SMF, NEF, UPF, and PCF, such as specific functions, connection relationships, and implementation methods, please refer to the relevant descriptions in relevant technologies (e.g., 3GPP protocols).

[0076] The Ambient IoT Function (AIOT-F) 15 can be used to provide management and control for AIoT services.

[0077] For example, AIOT-F 15 can receive AIoT service requests from AF and provide AIoT service-related information to AF, such as AIoT service execution results; perform AIoT service control, such as inventory processing; perform device context management and reader context management, such as reader selection and information configuration.

[0078] Referring to Figure 2, which is a schematic diagram of a second communication architecture of an AIoT system provided by an embodiment of the present disclosure, the differences between the second communication architecture and the first communication architecture are described below.

[0079] Specifically, the reader / writer may be a base station reader / writer 23. For example, the base station reader / writer 13 may be integrated into or externally connected to the base station.

[0080] AIoT-F can be integrated or externally connected to a variety of core network devices, such as the AMF supporting AIoT-F 24 shown in Figure 2.

[0081] It should be noted that AIoT-F can also be integrated or connected to other appropriate core network devices, such as UDM, AF, etc.

[0082] Between the AMF supporting AIoT-F 24 and AF17, or between the AIoT-F 15 and AF17 shown in FIG1 , communication can be achieved through a service based interface (SBI).

[0083] It should be noted that the communication architecture in the present disclosure is not limited to that shown in Figures 1 and 2. For example, the AIoT-F15 shown in Figure 1 can also be integrated with or externally connected to the AMF14, similar to replacing the AMF14 and AIoT-F15 shown in Figure 1 with the AMF supporting AIoT-F 24 shown in Figure 2.

[0084] For example, the AMF supporting AIoT-F24 shown in Figure 2 can be replaced with a structure in which AMF and AIoT-F are separated. For example, the AMF supporting AIoT-F 24 shown in Figure 2 can be replaced with AMF14 and AIoT-F15 shown in Figure 1.

[0085] 3, which is a schematic diagram of a first communication method provided by an embodiment of the present disclosure. The communication method shown in FIG1 may include S31 to S32. In this disclosure, the S in each step number represents a step.

[0086] It should be noted that the communication method shown in Figure 3 can be used for AIoT-F. As mentioned above, AIoT-F can be an independent communication device, and can also be integrated with or externally connected to appropriate core network equipment.

[0087] S31, AIoT-F sends AIoT instructions to the reader.

[0088] Among them, the reader / writer shown in Figure 3 is selected from N readers / writers in at least one reader / writer, and the N readers / writers are determined based on information of at least one reader / writer and / or information of the target device, and the target device is a device adapted to the N readers / writers.

[0089] Correspondingly, the reader receives AIoT instructions.

[0090] Among them, the AIoT instruction can be an instruction obtained by AIoT-F after compiling the received AIoT requirements, which can be recognized by the reader.

[0091] In some embodiments, for example, the target device may be determined based on information sent by the AF.

[0092] Among them, AF can specify a specific AIoT device and can also provide information of the target device to enable AIoT to determine the AIoT device.

[0093] In a specific embodiment, the AF sends the device ID of the target device to the AIoT-F.

[0094] Specifically, AF specifies the AIoT device by providing the device ID of the AIoT device to AIoT-F.

[0095] In another specific embodiment, the AF sends information for determining the target device to the AIoT-F.

[0096] Specifically, AF provides AIoT-F with information of the AIoT device, such as model, brand, product name, etc., so that AIoT-F determines the AIoT device based on the information used to determine the target device.

[0097] In the solution of the embodiment of the present disclosure, before sending the AIoT instruction to N readers among the at least one reader / writer, the method may further include: determining the N readers / writers.

[0098] The N readers / writers may be readers / writers compatible with the target device, and the N readers / writers may be determined based on information of at least one reader / writer and / or information of the target device.

[0099] The information of at least one reader / writer may include one or more of the following: the coverage of each reader / writer in at least one reader / writer; the location information of each reader / writer in at least one reader / writer; the operating frequency of each reader / writer in at least one reader / writer; and the operating time range of each reader / writer in at least one reader / writer.

[0100] The following is a description of the various parameters:

[0101] (i) The coverage of a reader / writer may include the communication distance and / or communication angle of the reader / writer.

[0102] (ii) Communication distance can be used to indicate the communication capability of a reader / writer, for example, the maximum communication distance over which a reader / writer can communicate with other communication devices.

[0103] (iii) The communication angle may be used to indicate the angle at which the reader can send and receive signals, and may include, for example, a horizontal angle and a vertical angle.

[0104] (iv) Location information can be used to indicate the location of the reader, such as latitude and longitude, altitude, floor number, room number, cell, etc.

[0105] It should be noted that the reader is a UE reader, the position of the UE can be considered as the position of the UE reader, the reader is a base station reader, and the position of the base station can be considered as the position of the base station reader.

[0106] (v) Operating frequency can be used to indicate the operating frequency at which the reader can transmit and receive signals, for example, using a frequency band or a frequency point.

[0107] (vi) The operating time range may be used to indicate the operating time during which the reader can send and receive signals, for example, in the Universal Time or in the local time at which the reader is located.

[0108] The target device information may include one or more of the following: the communication range of the target device; the communication distance of the target device; the location information of the target device; the operating frequency of the target device; the operating time range of the target device; and the energy collection method of the target device.

[0109] The following is a description of the various parameters:

[0110] (i) The communication range of the target device may include the communication distance of the target device and / or may include the location information of the target device.

[0111] (ii) The communication distance may be used to indicate the communication capability of the target device, for example, the maximum communication distance over which the target device can communicate with other communication devices.

[0112] (iii) The location information may be used to indicate the location of the target device, and may be an absolute address, such as described using longitude and latitude, or may be location information defined by a third party.

[0113] (iv) Operating frequency can be used to indicate the operating frequency at which the target device can transmit and receive signals, for example, using a frequency band or a frequency point.

[0114] (v) The operating time range may be used to indicate the operating time during which the target device can send and receive signals, for example, in the Universal Time or in the local time at which the target device is located.

[0115] (vi) Energy harvesting method can be used to indicate the way in which the target device collects energy from the environment, which can also be referred to as the energy source type, such as solar energy, kinetic energy, radio energy, or wind energy.

[0116] Understandably, by determining how the target device collects energy from the environment, the operating time range of the target device can be determined. For example, the operating time range of a target device powered by solar energy may be daytime.

[0117] The following non-restrictive description of the AIoT-F method for determining N readers and writers is provided in conjunction with the accompanying drawings.

[0118] Example 1

[0119] Referring to Figure 4, Figure 4 is an interactive diagram of the first method for AIoT-F to determine N readers and writers provided by an embodiment of the present disclosure. The method shown in Figure 4 may include S41, S43, and S45. Optionally, the method shown in Figure 4 may also include S42 or S44.

[0120] S41, AMF sends the location information of the reader to AIoT-F, and correspondingly, AIoT-F receives the location information from AMF.

[0121] In one embodiment of the present disclosure, AMF sends the location information of the reader to AIoT-F, and can also use the same signaling to carry and send the IDs of N readers to enable AIoT-F to identify multiple readers.

[0122] In another embodiment of the present disclosure, another signaling may be used to carry and send the IDs of N readers, so that the AIoT-F receives the location information and ID of the reader respectively.

[0123] Specifically, AMF can send the reader information (such as the location information shown in Figure 4) to AIoT-F in the following ways:

[0124] (1) The reader is a UE reader. The UE reader sends the reader information to the base station, which is then sent to the AMF through the base station, and then to the AIoT-F through the AMF.

[0125] (2) The reader is a base station reader. The base station reader sends the reader information to AMF, and then sends it to AIoT-F through AMF.

[0126] (3) The reader is a base station reader, and the reader information is stored in the UDM in advance. Among them, the AMF can obtain the reader information by sending a request to the UDM.

[0127] For example, the Operations, Administration and Maintenance (OAM) network element may store the reader information into the UDM in advance.

[0128] In one embodiment, the location information of the target device is used to indicate the target area. Specifically, when AIoT-F queries the UDM for location information, the UDM can convert (map) the location information into 3GPP location information, such as cell ID, tracking area, and an area corresponding to the AIoT operation. The target device is considered to be located in the target area with a high probability, and the AIoT command can be executed starting from the target area.

[0129] In another embodiment, the location information of the target device may further include coordinate information. Specifically, by providing the coordinate information of the target device, the location of the target device may be determined.

[0130] In yet another embodiment, the location information of the target device may also be location information defined by a third party.

[0131] It should be noted that the AMF shown in Figure 4 is an example of a core network element, and the reader information can also be received from other appropriate core network elements, such as OAM, AF, other appropriate servers, etc.

[0132] S42, the target device sends the communication range of the target device to AIoT-F, and correspondingly, AIoT-F receives the communication range of the target device from the target device.

[0133] The communication range of the target device may include the communication distance of the target device and / or may include the location information of the target device.

[0181] Specifically, the target device can send the target device information to AIoT-F in the following ways (as shown in the communication range of Figure 6):

[0182] (1) The reader is a UE reader. The target device sends the target device's information to the UE reader, which is then sent to the base station through the UE reader, sent to the AMF through the base station, and then sent to the AIoT-F through the AMF.

[0183] (2) The reader is a base station reader. The target device sends the target device information to the base station reader, which then sends the target device information to AMF through the base station reader, and then sends it to AIoT-F through AMF.

[0187] S64, AIoT-F receives the communication range of the target device from AF, and correspondingly, AF sends the communication range of the target device to AIoT-F.

[0188] It should be noted that in one embodiment of the present disclosure, the communication range of the target device can be sent together with the service trigger instruction in S63, and does not need to be sent separately.

[0189] S65, AIoT-F determines N readers / writers.

[0190] The location of each of the N readers is within the communication range of the target device, and the location of the target device is within the coverage range of each reader.

[0191] In a specific embodiment, the communication range of the target device may be a coordinate range in which the target device can support communication, and the coverage range of the reader / writer may be a coordinate range in which the reader / writer can support communication.

[0192] Specifically, AIoT-F can confirm whether the position of each reader / writer in at least one reader / writer falls within the coordinate range of the target device by determining the coordinate range of the target device; AIoT-F can also confirm whether the position of the target device falls within the coverage range of each reader / writer in at least one reader / writer by determining the coverage range of the reader / writer, and determine that the reader / writer is selected in response to the reader / writer falling within the coordinate range of the target device and the target device falling within the coverage range of the reader / writer.

[0194] In one or more of the methods shown in Examples 1 to 3, AIoT-F can select multiple readers and writers, and the multiple readers and writers can have communication paths in different directions with the target device.

Therefore, when there are obstructions around the target device, resulting in poor communication effect, by selecting readers / writers in different directions, signal obstruction can be reduced and the communication success rate can be improved.

[0196] In one or more of the methods shown in Examples 1 to 3, AIoT-F can also select multiple readers and writers and provide time-sharing information to the readers and writers.

[0198] In the embodiment of the present disclosure, considering that the target device may not be able to communicate with multiple readers at the same time, resulting in reduced communication effect, the communication success rate of the target device can be improved by providing time-sharing information to the readers.

[0227] S84, AIoT-F receives the operating time range and / or energy collection method of the target device from AF, and correspondingly, AF sends the operating time range and / or energy collection method of the target device to AIoT-F.

[0228] It should be noted that in one embodiment of the present disclosure, the operating time range and / or energy collection method of the target device can be sent together in the service trigger instruction in S53, and do not need to be sent separately.

[0229] It should be noted that some operating time ranges and / or energy collection methods are relatively fixed and can be confirmed in advance and sent through AF, such as using solar energy to collect energy.

[0230] Some operating time ranges and / or energy harvesting methods are more flexible and can be emitted by the target device through S82, such as harvesting energy from the movement of animals.

[0232] Part or all of the operating duration range of the target device is within the operating duration range of each of the N readers / writers.

[0233] The operating time range of the target device may be determined according to the energy harvesting method of the target device.

[0234] In a specific embodiment, AIoT-F can compare the operating duration range of the target device with the operating duration range of each reader / writer in at least one reader / writer, and determine that the reader / writer is selected in response to part or all of the operating duration range of the target device being within the operating duration range of a single reader / writer.

[0235] In the embodiment of the present disclosure, by partially or completely locating the operating duration range of the target device within the operating duration range of each reader / writer in the N readers / writers, the communication success rate between the reader / writer and the target device can be improved, and the reliability of transmission and reception can be improved.

[0236] It should be noted that, in a specific implementation, the multiple methods shown in the first to fifth embodiments may be combined to determine the N readers / writers.

[0237] Specifically, the information of the reader / writer may include both coverage information of the reader / writer and position information of the reader / writer, so as to improve the accuracy of the information by combining the coverage information and the position information.

[0238] In addition, the information of the reader may also include the operating frequency of the reader and the operating time range of the reader, so that the working information and capability information of the reader can be determined by combining multiple dimensions.

[0239] Similarly, the information of the target device may include both the communication range of the target device and the communication distance and location information, so as to combine multiple information to improve the accuracy of the information.

[0240] In addition, the target device information may also include the operating frequency of the reader, the operating time range of the target device, and the energy collection method of the target device, thereby combining multiple dimensions to determine the operating information and capability information of the target device.

[0241] In one or more methods shown in Embodiments 1 to 5, the information of the target device may be received from the AF, or the information of the target device may be converted based on information received from the application function AF.

[0242] For example, the following four situations can convert 5G information (Map the information obtained from AF into 5GS information):

[0243] (1) The communication range of the target device;

[0244] (2) Communication distance of the target device;

[0245] (3) Location information of the target device;

[0246] (4) The operating frequency of the target device.

[0247] In one or more methods shown in Examples 1 to 5, the information of each reader / writer and the information of the target device can be specific information sent and received, or a mapping relationship between preset specific information and an index, and then the receiver confirms the specific information by sending and receiving the index.

[0248] In one or more of the methods described in Examples 1 to 5, when AMF sends the reader's location information to AIoT-F, it may also send the reader's ID, so that AIoT-F can identify multiple readers. In addition, when the target device sends the target device's information to AIoT-F, it may also send the target device's ID, so that AIoT-F can identify multiple devices. When AF sends the target device's information to AIoT-F, it may also send the target device's ID, so that AIoT-F can identify multiple devices.

[0249] 9, which is a schematic diagram of a second communication method provided by an embodiment of the present disclosure, the method shown in FIG9 may include S92 and S31.

[0250] S92: AIoT-F sends configuration information to the reader. Correspondingly, the reader receives the configuration information from AIoT-F.

[0251] S31, AIoT-F sends an AIoT command to the reader. Correspondingly, the reader receives the AIoT command from AIoT-F.

[0252] For more information about how AIoT-F sends AIoT commands to the reader, please refer to the previous description and will not be repeated here.

[0253] The N readers / writers are located in the UE, and the configuration information is used to establish a PDU session associated with the N readers / writers.

[0254] Furthermore, the configuration information may include read and write information of N readers and writers; wherein the read and write information of the N readers and writers may include one or more of the following: the read and write communication distance of each reader and writer; the read and write operating frequency of each reader and writer; and the read and write operating time range of each reader and writer.

[0255] In a specific implementation, the configuration information may include the read / write information of the reader / writer to which the reader / writer ID belongs. The read / write information may include one or more of the following: the read / write communication distance, read / write working frequency, and read / write working time range of the reader / writer to which the reader / writer ID belongs.

[0256] It should be noted that the read / write information of the reader to which the reader ID belongs can be used to represent the actual working parameters of the reader and the target device, which is different from the reader information mentioned above, which can be used to represent the capabilities of the reader.

[0257] Specifically, the read / write communication distance can be selected from the communication distance supported by the reader / writer, for example, a portion of the communication distance. Similarly, the read / write operating frequency can be a portion of the operating frequency supported by the reader / writer, and the read / write operating duration range can be a portion of the operating duration range supported by the reader / writer.

[0258] In an embodiment of the present disclosure, a PDU session may be established by AIoT-F sending configuration information to the reader / writer before AIoT-F sends an AIoT instruction to the reader / writer.

[0259] Furthermore, the reader is located in the UE, and the method further includes: sending a first message to the UE, where the first message includes the reader ID; wherein the first message is used to establish a PDU session associated with the reader.

[0260] 10 , which is a schematic diagram of a method for establishing a PDU session according to an embodiment of the present disclosure, may include S101 to S1010 .

[0261] S101, AIoT-F sends a first message to UE, and correspondingly, UE receives the first message from AIoT-F.

[0262] The first message includes the ID of each reader / writer in the at least one reader / writer.

[0263] In one embodiment of the present disclosure, AIoT-F further performs one or more of the following:

[0264] 1) AIoT-F determines the PDU session corresponding to the UE associated with each UE reader and provides configuration information to each UE reader.

[0265] 2) AIoT business information, such as operation instructions and operation results, is transmitted through the user plane of the UE PDU session associated with the UE reader.

[0266] 3) AIoT-F determines the Quality of Service (QoS) parameters of the PDU session.

[0267] Furthermore, the QoS parameters may be preset; or, the QoS parameters may be determined according to the number of target devices received from the application function AF.

[0268] In a specific embodiment, the larger the number of target devices provided by the AF, the larger the QoS parameters assigned. Conversely, the smaller the number of target devices provided by the AF, the smaller the QoS parameters assigned.

[0269] Specifically, the QoS parameters may be adapted to the operation of AIoT, and the QoS parameters may be preset, for example, determined by an operator.

[0270] The QoS parameters may be determined based on the number of target devices received from the application function AF, for example, may be converted (mapping) from the relevant quality of service requirements provided by the AF, and the conversion is performed by the AIoT-F.

[0271] S102, UE requests SMF to establish a PUD session.

[0272] Exemplarily, the UE may establish a secure user plane connection with the AIoT-F, and use a network triggered PDU Session Establishment procedure to establish a PDU session of the UE to which the UE reader associated with the AIoT service belongs.

[0273] Specifically, the UE can use the UE Route Selection Policy (URSP) that includes AIoT services. The UE establishes relevant PDU session parameters (such as dedicated data network name (DNN) and single network slice selection assistance information (S-NSSAI)) and QoS parameters for AIoT services such as inventory, reading, and writing.

[0274] Specifically, the UE can send a request to the base station, send it to the AMF through the base station, and send it to the SMF through the AMF.

[0275] S103, SMF sends a query request to AIoT-F.

[0276] The query request includes the reader ID.

[0277] Specifically, SMF queries AIoT-F for information related to AIoT services, such as related information of associated PDU sessions.

[0278] S104: AIoT-F sends configuration information to SMF.

[0279] S105: AIoT-F sends QoS parameters to SMF.

[0280] It should be noted that there is no particular order in which S104 and S105 are executed.

[0281] In one embodiment, AIoT-F may use a first signaling to send configuration information to SMF, and use a second signaling to send QoS parameters to SMF.

[0282] In another embodiment, AIoT-F can use the same signaling to send configuration information and QoS parameters to SMF.

[0283] Specifically, AIoT-F sends AIoT service-related information to SMF, such as the PDU session information of the UE corresponding to the corresponding UE reader / writer.

[0284] In a specific embodiment, the information associated with the AIoT service may include configuration information and QoS parameters of the reader / writer, and may also include communication distance and working time range (such as start and end time).

[0285] S106: The SMF sends a first PDU session message to the UE.

[0286] The PDU session message can carry the configuration information of the reader / writer. The configuration information can include the read / write information of the reader / writer to which the reader / writer ID belongs.

[0287] In a specific embodiment of the present disclosure, the configuration information may further include one or more of the following: the communication distance of the reader / writer, and the working time range of the reader / writer (such as the start and end time).

[0288] S107: The UE sends configuration information to the UE reader.

[0289] S108: The UE reader sends the configuration result to the UE.

[0290] The configuration result may include: configuration success, configuration failure, and other appropriate configuration result information.

[0291] S109: The UE sends a second PDU session message to the SMF.

[0292] The second PDU session message may include the configuration result of the UE reader / writer.
