[0098] like Figure 2 As shown, a terminal identifier (such as the identifier of an Ambient Internet of Things (AIoT) device) includes the following information:

[0099] 1) First part of the information:

[0100] -ID type, including at least one of the following:

[0101] The indication may or may not include information related to network identification;

[0102] Information that includes or excludes information from third parties;

[0103] Information indicating Part 2 type, including Electronic Product Code (EPC) or other types of Part 2 (such as Part 2 assigned by the operator).

[0104] - A network identifier, including at least one of the following: Mobile Country Code (MCC), Mobile Network Code (MNC), Network Identifier (NID), indicating whether or not the network identifier is included. When the network identifier is included, the terminal identifier contains the network identifier.

[0105] - Third-party information, indicating whether or not information from a third party is included. If the terminal identifier includes information from a third party, the terminal identifier contains that third-party information.

[0106] - Information used to indicate the length or length type of Part2.

[0107] 2) Second part of the information:

[0108] - Used to distinguish different terminal devices within the scope indicated by the information in Part One.

[0109] The second part can be manifested as: EPC or other types of second parts (such as the second part allocated by the operator).

[0110] The terminal identifier includes a first part and a second part. All or part of the first part or the second part (Part 2) can be used to construct filter information for filtering one or more terminal devices (such as AIoT devices, or other terminal devices besides AIoT devices).

[0111] The filter information may include one or more components.

[0112] For example, if the paging message includes filter information, the AIoT device receiving the paging message determines that its identifier matches or includes the filter information, then it considers itself to be the paging target device and responds to the paging.

[0113] Therefore, in order to determine which of the above information can be used to filter or screen terminal devices, the following issues also need to be addressed:

[0114] The AIoT device identifier comprises a first part (Part 1) and a second part (Part 2). All or part of the second part can be used to construct filter information for filtering one or more terminal devices (such as AIoT devices). The filter information may include one or more components. For example, if a paging message includes filter information, and the first AIoT device receiving the paging message determines that its identifier includes the filter information, it considers itself to be the paging target device and thus responds to the paging.

[0115] The structure of the first part may be:

[0116] <Operator B>,

[0117] <Brand A>,

[0118] <Operator B><Brand A>,

[0119] or be empty.

[0120] The structure of the second part may be <Mobile phone><Blue><Folding screen>;

[0121] The Filter information may be <Mobile phone><Folding screen>.

[0122] If both the second part of the terminal identifier and the Filter information are strings in an undefined format, then the AIoT device has no way to match which part of the string conforms to the Filter information.

[0123] As Figure 3 shown, the Filter information consists of two parts of information (A and B). If the Filter information is a string, then the AIoT device cannot recognize that A and B are two pieces of information, and thus cannot match the two pieces of information separately on Part2. Instead, it treats A and B as one piece of information and considers itself unmatched.

[0124] Therefore, regarding how to implement the matching of filtering information (including how to improve the efficiency of matching filtering information), the following detailed issue 1: How to define the format of the filtering information or the format of the terminal identifier to improve the efficiency of matching the filtering information.

[0125] In one embodiment, the terminal identifier can be defined as components in different paragraphs, such as in the form of a URI. For example, different Components (subsequent called component information) in Part2 are separated by punctuation marks, so that the AIoT device can easily solve the problem of matching the Filter information.

[0126] Format example: Component1.Component2.Component3;

[0127] Value example: Mobile phone.Blue.Folding screen.

[0128] Therefore, the Filter information can also be presented in the form of a URI, such as Brand A.Folding screen or just a sequence of components.

[0129] [[ID=,45]]The terminal identifier can also be presented in the form of base-X, but different parts can still be separated by punctuation marks. The base-X is to convert the above string into a base-X number.

[0130] For example: 56342.13445.7889000.

[0131] like Figure 5 The diagram illustrates that the filter information contains multiple strings used for filtering. After identifying the filter information from the second part, it is assumed that the second part matches the filter information; for example... Figure 4 and Figure 6 The diagram shows a filter information containing a string used for filtering. After the filter information is identified from the second part, it is considered that the second part matches the filter information.

[0132] Additionally, regarding question 2: Part 2 (the second part) may contain components of different types, quantities, and lengths. This results in different Part 2 types and corresponding lengths (e.g., number of bits). Therefore, how to implement the matching problem of filtering information (including how to improve the efficiency of filtering information matching) includes the following detailed question 2: How to define the terminal identifier and the information of the second part, or components, to improve the efficiency of filtering information matching.

[0133] One solution is to indicate at least one of the following through a piece of information (such as the first piece of information): the type of Part2, the length of Part2 or the type of the length, and the information of the Component in Part2.

[0134] The information of the Component is used to describe the Component, or to indicate at least one of the following: the meaning of the Component, the length of the Component, and the type of the Component. The first information is placed in Part 1. In one embodiment, the first information may include the type of Part 2; in another embodiment, the first information may embody the type of Part 2 (also referred to as the encoding pattern of Part 2), that is, based on the first information (such as the type of Part 2), at least one of the following of Part 2 is determined: the information of the Component in Part 2, and the length of Part 2;

[0135] Example of Part 1: ID type.B carrier.A brand.Part 2 type.Part 2 length type (the order of these pieces of information is not restricted);

[0136] The length or length type of Part 2 can take values ​​such as 32 bits, 96 bits, 128 bits…496 bits, 8 bytes, 16 bytes. This application does not impose any specific value limitations. The stated values ​​also do not limit the scope of this invention.

[0137] Another solution is to not distinguish between Part 1 and Part 2. Information in Part 1, such as third-party information, is also identified by network identifiers as components (e.g., components).

[0138] Information (such as second information) can be used to indicate at least one of the following: the type of the identifier, the length of the identifier, and information about the components in the identifier. The information about the components indicates at least one of the following: the meaning of the component, the length of the component, and the type of the component. In one embodiment, the first information may include the type of the identifier; in another embodiment, the first information may embody the type of the identifier (also known as the identifier's encoding pattern). That is, based on the type of the identifier, at least one of the following is determined: the components in the identifier; the information about the components describes the component, or indicates at least one of the following: the meaning of the component, the length of the component, and the type of the component.

[0139] Therefore, how to achieve the matching of filtered information (including how to improve the efficiency of filtering information matching), including information in the terminal device or terminal identifier in Question 3, can be used to match filtered information. However, with a large amount of information, exhaustive enumeration is not realistic, and how to improve the matching efficiency of filtered information is still unclear.

[0140] One approach is to provide, along with the filtering information, at least one of the following: information indicating a storage area in the terminal device, information indicating a start position, information indicating the length of the filter information, information indicating the use of a terminal identifier to match the filter information; and third information; the third information being used to indicate matching information in the terminal device or terminal identifier.

[0141] In one optional embodiment of this application, the first part is the portion of the terminal identifier other than the second part.

[0142] The first part includes at least one of the following: the type of terminal identifier, the type of the second part, information indicating the presence or absence of a network identifier, information indicating the presence or absence of third-party information, information indicating the presence or absence of a network identifier, information indicating the presence or absence of third-party information, information A, and information B;

[0143] in,

[0144] The third-party information (short for third-party information) is used for at least one of the following:

[0145] To identify, locate, identify, indicate, or index third parties;

[0146] To identify, locate, index, identify, or indicate certified equipment;

[0147] Identify, locate, index, identify, or indicate data management devices

[0148] in,

[0149] The A information is used to indicate or describe at least one of the following: the encoding structure of the terminal identifier, the definition of the terminal identifier, the type of the terminal identifier, the length of the terminal identifier, and information about the components in the terminal identifier;

[0150] The B information is used to indicate or describe at least one of the following: the encoding structure of the second part, the definition of the second part, the type of the second part, the length of the second part, and information about the components in the second part; the second part is the second part of the terminal identifier.

[0151] In one optional embodiment of this application, the second part is the part of the terminal identifier other than the first part, or information used to distinguish, identify, screen or filter terminal devices within the range indicated by the first part;

[0152] In one alternative embodiment of this application, the second part includes one of the following: Electronic Product Code (EPC), or other types of second parts (such as operator-assigned or 3GPP-defined second parts). Other types of second parts include those other than EPC.

[0153] In one optional embodiment of this application, the component (e.g., component) is also referred to as an element. The terminal identifier, first information, first part, or second part can be divided into one or more components. The component can be understood as one of the following: information component, information paragraph, information segment.

[0154] Optionally, the information about the component is used to describe the component, or to indicate at least one of the following: the definition of the component, the type of the component, the length of the component, or the length type.

[0155] The component information can be used to screen or filter one or more terminal devices or to constitute information. This information can be used to indicate, identify, filter, or select information from one or more terminal devices. Given the large number of terminal devices, it is easy to understand that using components to indicate, identify, filter, or select multiple terminal devices is more efficient. Therefore, the components can also be called filtering information or screening information. The components can be given other names; this invention does not impose any limitations.

[0156] To meet the intelligent needs of the Internet of Things (IoT), Ambient Internet of Things (AIoT), also known as Ambient Power-enabled Internet of Things (AIoT), has been introduced. This is a type of IoT service. A terminal device, such as an AIoT device, is a low-power IoT device. These devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to their low overall power consumption, the energy for communication can come from the environment, such as wind power, kinetic energy, heat energy, and radio frequency (RF) signals. AIoT devices can also be described as passive IoT devices or responder devices. AIoT devices are typically in a state without Radio Resource Control (RRC) and do not perform mobility management.

[0157] In one optional embodiment of this application, "determine" can be understood as "decide".

[0158] In one optional embodiment of this application, the traffic initiated by the terminal device is triggered by traffic, signaling, or data terminated at the terminal device, which can be referred to as DoDTT: Device-originated-device-terminated-triggered (DO-DTT). For example, the device-originating traffic is triggered by the device terminated traffic or signaling.

[0159] In one optional embodiment of this application, traffic terminated at the terminal device can be referred to as DT (Device-terminated (DT), e.g., The traffic is terminated at the AIoT device.)

The AIoT function includes, but is not limited to, at least one of the following:

[0172] 1) Responsible for the management and control of AIoT operations (i.e., operations on terminal devices; AIoT operations can also be referred to as one of the following AIoT tasks or AIoT processes);

[0173] 2) Determine whether to authorize the customer's AIoT operation request;

[0174] 3) Distribute AIoT operations to readers or devices that communicate directly with terminal devices (either by sending directly or by forwarding through other network elements);

[0175] 4) Receive the results of AIoT operation execution;

[0176] 5) Summarize the AIoT operation execution results;

[0177] 6) Send the AIoT operation results to the customer.

[0178] Optionally, the AIoT functionality may further include at least one of the following: a first AIoT functionality, and a second AIoT functionality:

[0191] 5) Send the execution result of the AIoT task to the first AIoT function.

[0192] In one implementation, the AIoT operation request is used to request an AIoT operation.

[0193] In one implementation, the AIoT function can be a separate network function, or an existing network function (such as an AMF (e.g., an AMF that supports AIoT functions) or a NEF (e.g., a NEF that supports AIoT functions)).

[0194] In one implementation, NEF can support a first AIoT function, and AMF can support a second AIoT function or an AIoT function.

[0195] In one embodiment of this application, the operation is a first operation, or the first operation may be simply referred to as an operation.

[0196] In one embodiment of this application, the first operation may also be referred to as an AIoT operation (operation on the terminal device).

[0197] In one implementation, the AIoT operation may also be referred to as one of the following: AIoT task, AIoT process, AIoT command, or AIoT service.

[0198] In one implementation, the first operation may also be referred to as one of the following: first task, first process, first command, first service.

[0199] Optionally, the sources of the operation, the first operation, the AIoT operation, or the operation on the terminal device can be different, and may include at least one of the following:

[0200] 1) Operations on the terminal device requested by AF or a third party (such as an application server), such as inventorying the target terminal device, reading the target terminal device, writing to the target terminal device, enabling the target terminal device, or disabling the target terminal device;

[0201] 2) Operational requests to terminal devices generated by core network devices (such as AIoT functions), or operations to terminal devices generated by core network devices (such as AIoT functions); such as interacting with the target terminal device to obtain information from the terminal device, or configuring information to the target terminal device;

[0202] 3) Operation requests (such as operation commands) to the terminal device from the reader, access network equipment (such as RAN) or UE, or operations to the terminal device generated by the reader, RAN or UE.

[0203] Optionally, the target terminal device includes one or more terminal devices. The target terminal device can be determined using information used to indicate and / or filter terminal devices. The target terminal device can be the object or target of the first operation (including related operations of the first operation). Alternatively, the target terminal device can refer to one or more terminal devices.

[0204] The first operation (also referred to as an AIoT operation) may include one or more operations on a terminal device; the terminal device may be one or more terminal devices.

[0205] In one implementation, the operation or the first operation (such as an operation performed on the terminal device) includes at least one of the following:

[0206] 1) Operations for inventorying terminal devices (such as filtering terminal devices, paging terminal devices, querying terminal devices, discovering terminal devices, identifying terminal devices, and obtaining the identifier of terminal devices, at least one of the following):

[0207] 2) At least one of the following: screening terminal devices, discovering terminal devices, identifying terminal devices, obtaining the identifier of terminal devices, authenticating terminal devices, and authorizing terminal devices (which can be referred to as the operation of inventorying terminal devices);

[0208] 3) Obtaining information from terminal devices (such as information stored in the terminal device or information sensed by sensors associated with AIoT, which can be simply referred to as a read operation or an information reading operation; in one implementation, simply obtaining the identifier of the terminal device may not be considered a read operation).

[0209] 4) Configure information to the terminal device (which can be simply referred to as a write operation, or the operation of writing information);

[0210] 5) Enable the RF capability of the terminal device (which can be referred to as activation or enable operation);

[0211] 6) Disable the RF capability of the terminal device (which can be simply referred to as deactivation or disabling operation);

[0212] 7) Controlling the terminal device to execute commands (e.g., sending commands to the terminal device to control the actuators associated with the terminal device or the terminal device to execute the commands. This can be referred to as a control operation).

[0213] 8) Positioning terminal equipment, etc.;

[0214] 9) The operation of transmitting information to the terminal device; (in one embodiment, the information may be transparent to at least one of the reader and CN device (such as AIoT function))

[0215] 10) Operation of obtaining information from terminal devices (in one embodiment, the information may be transparent to at least one of the reader and CN device (such as AIoT function)).

[0216] In another implementation, the operation on the terminal device includes at least one of the following:

[0217] 1) Inventory operations (or other names may be used) include at least one of the following: filtering terminal devices, paging terminal devices, querying terminal devices, discovering terminal devices, identifying terminal devices, obtaining the identifier of terminal devices, authenticating terminal devices, and authorizing terminal devices;

[0218] 2) Positioning operations, including positioning terminal devices;

[0219] 3) Command operations.

[0220] Optionally, the command operation includes at least one of the following:

[0221] 1) Obtain information from the terminal device;

[0222] 2) Configure information for the terminal device;

[0223] 3) Enable the RF capability of the terminal device;

[0224] 4) Disable the RF capability of the terminal device;

[0225] 5) Control terminal equipment, etc.;

[0226] Optionally, the command operation (also referred to as the operation of interacting with information with the terminal device) includes at least one of the following:

[0227] 1) The operation of transmitting information to the terminal device; (in one embodiment, the information may be transparent to at least one of the reader / writer and the CN device (such as an AIoT function))

[0228] 2) Operation of obtaining information from terminal devices (in one embodiment, the information may be transparent to at least one of the reader and CN device (such as AIoT function).

[0229] It is easy to understand that when the information is transparent to at least one of the reader / writer and the CN device (such as AIoT functionality), the information transmitted to the terminal device does not need to be distinguished: configuration information sent to the terminal device and control commands sent to the terminal device. Similarly, the information obtained from the terminal device does not need to be distinguished: configuration information sent by the terminal device, responses to control commands sent to the terminal device, and information read from the terminal device.

[0230] However, it is not difficult to understand that the command operation, read operation, write operation, control operation, activation operation, and deactivation operation also need to perform at least one of the following: filtering terminal devices, paging terminal devices, querying terminal devices, discovering terminal devices, identifying terminal devices, authenticating terminal devices, and authorizing terminal devices.

[0231] It should be noted that the information used to request the execution of the first operation (which may be referred to as the operation or AIoT operation) (which may be simply referred to as the information used to request the first operation) may include information about the related operations used to request the execution of the first operation.

[0232] The related operations of the first operation (also referred to as operations related to the first operation) include, but are not limited to, the first operation. For example, the related operations of the first operation can be determined based on the first operation (such as a command operation (such as a write operation)). The related operations of the first operation can be determined based on the requested first operation. In addition to the first operation, the related operations of the first operation may also include at least one of the following: filtering terminal devices, paging terminal devices, querying terminal devices, discovering terminal devices, identifying terminal devices, obtaining the identifier of terminal devices, authenticating terminal devices, and authorizing terminal devices. It is easy to understand that, in one embodiment, the first operation, such as a command operation (such as a write operation), can only be performed on the terminal device after filtering, paging, querying, discovering, identifying, and / or authenticating the terminal device.

[0233] Optionally, the first command includes one of the following: an AIoT command, a command that requires communication with the terminal device; the first command requires communication with the terminal device.

[0234] Optionally, the first operation command includes one of the following: an AIoT command, an operation command that requires communication with the terminal device; the first operation command requires communication with the terminal device.

[0235] Optionally, the first task includes one of the following: an AIoT task, a task that can only be accomplished by communicating with a terminal device; the first task requires communication with a terminal device.

[0236] Optionally, the first process includes one of the following: an AIoT process, a task that can only be performed by communicating with the terminal device; the first process requires communication with the terminal device.

[0241] In one optional embodiment of this application, the first communication device or reader (such as a reader) may be a device having one of the following characteristics:

[0242] - An access device (also known as an AIoT wireless access device or AIoT wireless access system) supports at least one of the following: communicating with a terminal device, communicating with the terminal device based on a first interface, and performing AIoT operations; (It is easy to understand that the terminal device needs to communicate through a reader, so the reader can be called an access device)

[0243] -A device that communicates with a terminal device (such as a device that communicates directly with a terminal device) or a device that communicates with a terminal device based on a first interface;

[0244] - As an access device for terminal devices to access wireless communication systems;

[0245] - Devices that support the first interface;

[0246] - Devices that support the first RAT.

[0247] - Devices that support at least one of the following operations: inventory, read, write, activate, deactivate, command, AIoT operation.

[0248] In one implementation, the command includes at least one of the following: read, write, activate, deactivate.

[0249] In one implementation, the deactivation includes at least one of temporary deactivation and permanent deactivation.

[0250] In one optional embodiment of this application, communicating with the terminal device includes performing an AIoT operation on the terminal device. The AIoT operation is also referred to as the first operation.

[0251] In one optional embodiment of this application, the first RAT may be a RAT for AIoT (such as providing AIoT services), and the first RAN may be different from existing RATs such as NB IoT, 2G, 3G, 4G, or 5G.

[0252] In one embodiment of this application, the reader / writer device may also be referred to as an interrogator device.

[0253] In one embodiment of this application, the reader device is a device for communication between intermediate devices and core network devices, such as a terminal (e.g., UE), IAB, relay device, etc.

[0254] Optionally, a reader / writer device can refer to a device that supports reader / writer functionality (such as a UE or a base station). That is, in one implementation, the reader / writer device may support not only reader / writer functionality but also other functions; in another implementation, the reader / writer device only supports reader / writer functionality.

[0255] In one optional embodiment of this application, the reader may also be referred to as one of the following: a read / write device, a terminal for an AIoT service, an interrogator, a reader, a queryer, a communicator, a scanner, a programmer, a standalone device, a portable reader, an automatic device identification device, etc. This application does not impose naming restrictions on the reader.

[0256] In one optional embodiment of this application, the reader / writer can be a terminal (such as a UE), an access network device, or a device with read / write functionality. Devices with reader / writer functionality include, but are not limited to, one of the following: a UE with reader / writer functionality, or an access network device with reader / writer functionality.

[0257] In one implementation, the read / write device is a handheld or fixed device that reads (and sometimes writes) tag information, as defined in the original definition. It can also be understood as a device that communicates with the tag, such as a terminal (e.g., UE), a base station, or a device with read / write capabilities, such as a reader / writer; the specifics are not limited here.

[0258] In one implementation, the second interface includes at least one of the following:

[0259] Unlike the existing NG interface between RAN and CN,

[0260] The interface between the first communication device (such as "device that supports communication with terminal devices", reader) and the AIoT function;

[0261] The interface between the first communication device (such as "device supporting communication with terminal devices", reader) and the AMF function;

[0262] The interface between the first communication device (such as "device that supports communication with terminal devices", reader) and the core network equipment.

[0263] In one implementation, the device that supports communication with the terminal device is one of the following:

[0264] 1) A device that supports communication with a terminal device through a first interface, wherein the first interface is an access layer of an air interface supported by the terminal device;

[0265] 2) Devices that support communication with terminal devices via wireless interfaces;

[0266] 3) Fourth communication device, such as UDM, UDR, NRF, AIoT function, second AIoT function;

[0267] 4) AIoT functionality, second AIoT functionality;

[0268] 5) First AIoT function: AIoT function part directly connected to RAN.

[0269] 6) AMF access management and / or mobility management functions.

[0270] In one implementation, a communication method that involves backscattering or lacks the ability to generate active signals is defined as backscattering on an externally provided carrier wave.

[0271] In one embodiment, the active signal generation refers to the terminal device generating a signal itself.

[0272] Optionally, the second interface can be implemented in the following manner:

[0273] Method 1: Reuse the NG interface. For example, if the base station supports both terminal device (new wireless interface) communication and UE (traditional UU interface) communication, add a new IE to the required information of the NG interface.

[0274] Method 2: Reuse the NG interface. However, if the base station only supports terminal devices (new wireless interface), an instruction can be added to ignore the required IE that already exists but is not applicable to terminal devices, such as Default Paging DRX.

[0275] Method 3: Introduce a new interface, such as the second NG interface.

[0276] In one optional embodiment of the present invention, the first interface is a wireless interface between the "first communication device or reader / writer" and the terminal device. In one embodiment, the first interface may be different from another air interface of the Uu interface or the PC5 interface. In another embodiment, the first interface may be an enhancement of the Uu interface or an enhancement of the PC5 interface.

[0277] In one embodiment of this application, information for indicating and / or filtering terminal devices (such as information for indicating and / or filtering AIoT devices) can be used to indicate and / or filter one or more terminal devices (such as AIoT devices).

[0278] Information used to indicate and / or filter terminal devices includes at least one of the following: a terminal device identifier, an identifier for identifying a group of terminal devices (referred to as a group identifier), and matching information, information used to indicate the characteristics of the terminal devices.

[0279] 1. In one embodiment of this application, the information used to indicate and / or filter terminal devices includes the identifier of the terminal device. Here, the identifier of one terminal device can specifically refer to one terminal device. Multiple terminal device identifiers can specifically refer to multiple terminal devices. It is easy to understand that the identifier of a terminal device can uniquely identify that terminal device and is not shared by other terminal devices.

[0280] 2. In one embodiment of this application, the information used to indicate and / or filter terminal devices includes an identifier (referred to as a group identifier) ​​for identifying a group of terminal devices. In this case, a group identifier can specifically identify a group of terminal devices. It is easy to understand that the group identifier of a terminal device can uniquely identify that group of terminal devices and is not shared by other groups of terminal devices.

[0281] 3. In one embodiment of this application, the information used to indicate and / or filter terminal devices may not include the identifier of the terminal device. The information used to indicate and / or filter terminal devices may include matching information (which may not include the identifier of the terminal device). The matching information may not be unique to each terminal device, but may apply to a group of terminal devices (i.e., one or more terminal devices). Moreover, the number of this group of terminal devices may be uncertain. For example, it may be necessary to determine the identifier of the terminal device after it has provided feedback from the terminal device. When a terminal device has the matching information or information corresponding to the matching information, the terminal device can be considered as the target terminal device (i.e., the terminal device that successfully matches the information used to indicate and / or filter terminal devices, the terminal device of the first operation).

[0282] For example, in case 1, the terminal device stores matching information, such as "AAA". If the matching information is "AAA" and the terminal device also stores "AAA", then the match is successful. It is easy to understand that there may be multiple terminal devices storing "AAA".

[0283] For example, in case 2, the terminal device stores information corresponding to the matching information (this information may be different from the matching information, but it corresponds to it). For instance, if the matching information is "AAA" and the terminal device stores "BBB", since AAA and BBB have a corresponding relationship, it is considered a successful match. It is easy to understand that there may be multiple terminal devices storing "BBB".

[0284] In another implementation, the information used to indicate and / or filter terminal devices includes the identifier of the terminal device. In this case, the identifier of a single terminal device can specifically refer to one terminal device. Multiple identifiers of different terminal devices can specifically refer to multiple terminal devices. It is easy to understand that the identifier of a terminal device uniquely identifies that terminal device and is not shared by other terminal devices.

[0285] 4. In one embodiment of this application, the information for indicating and / or filtering terminal devices includes information for indicating the characteristics of the terminal devices. Since different terminal devices have different characteristics, the information for indicating the characteristics of the terminal devices can serve to indicate and / or filter terminal devices.

[0286] Optionally, the object requesting the first operation refers to the requester (also known as the client). The requester can be a certificate holder (such as the certificate holder of an AIoT device). There can be one or more objects requesting the first operation.

[0287] In one implementation, the object may be referred to as one of the following: customer, owner, owner, certificate holder (such as the certificate holder of the terminal device).

[0288] In one embodiment of this application, the service area or supported service area is at least one of the following: an area that provides AIoT services, an area that communicates with terminal devices (such as an area that communicates directly), or an area that supports AIoT operation.

[0289] In one implementation, the AIoT service enables the fulfillment of operational needs (such as a first operation) of a client, network, or reader on a terminal device.

[0290] In one implementation, the supported service areas differ from the existing TA (Target Area) list supported by the RAN equipment. Therefore, the supported service areas can be represented using different area information (i.e., area information different from the TAs). Alternatively, the currently supported TA list (e.g., the supported TA list in existing NG interface request messages) can be understood as the first TA, and the supported service areas as the second TA. When the RAN equipment simultaneously supports communication with the UE and communication with the terminal equipment, it can provide both the first TA list and the second TA list. The second TA list differs from the first TA list. When the RAN equipment supports communication with the terminal equipment, it can provide the second TA list. That is, the information used to indicate the supported service areas can be the second list.

[0291] The first communication device (such as a reader / writer) can communicate directly with the terminal device or through an intermediate device.

[0998] like Figure 14 As shown, this embodiment may include the following steps:

[0999] Step 0: Optionally, the fifth communication device sends the second information directly or indirectly to the first communication device (such as the AIoT function) or the fourth communication device (data management device).

[1000] The first communication device (such as an AIoT function) or the fourth communication device stores the second information.

[1001] Or the fourth communication device locally configures the second information.

[1008] Optionally, the request for requesting the first operation may include at least one of the following: filter information, information indicating a storage area in the terminal device, information indicating a start position, information indicating the length of the filter information, information indicating the use of a terminal identifier to match the filter information; and third information; the third information being used to indicate information in the terminal device or terminal identifier for matching.

[1009] Step 2: The first communication device (such as an AIoT function) sends a first operation request to the access network device (such as a reader / writer, which will be described as an example below). The first operation request may include at least one of the following: filter information, information indicating a storage area in the terminal device, information indicating a start position, information indicating the length of the filter information, and information indicating the use of a terminal identifier to match the filter information; third information; the third information is used to indicate the matching information in the terminal device or the terminal identifier.

[1010] Step 3: The second communication device receives the first operation request and, based on the first operation request, pages the terminal device. The paging includes first information. The first information is as described in the embodiment of the first communication device.

[1011] Step 4: The terminal device performs the first action, as described in the first communication device embodiment.

[1012] For example, the first behavior includes at least one of the following:

[1013] Receive a paging message from a second communication device, the paging message containing first information, the first information including at least one of the following: filter information, information indicating a storage area in the terminal device, information indicating a start position, information indicating the length of the filter information, information indicating that the filter information is matched using a terminal identifier; third information; the third information is used to indicate matching information in the terminal device or terminal identifier;

[1014] Based on the first information, determine at least one of the following: respond to or not respond to the paging, match or not match the filter information;

[1015] The filter information is information used to indicate, identify, filter, or screen one or more terminal devices.

[1016] In one implementation, if a first condition is met, at least one of the following is determined based on the filter information: responding to the paging and matching the filter information;

[1017] in,

[1018] The first condition includes at least one of the following:

[1021] In another embodiment, the filter information includes at least one of the following: filter information corresponding to the first part and filter information corresponding to the second part.

[1022] If the second condition is met, based on the filter information, at least one of the following is determined: responding to the paging and matching the filter information;

[1023] in,

[1024] The second condition includes at least one of the following:

[1025] The first part of the terminal identifier matches the filter information corresponding to the first part;

[1026] The second part of the terminal identifier matches the filter information corresponding to the second part.

[1027] like Figure 8 As shown, the terminal identifier includes the following component information: component 1, component 2, component 3, component 4, component 5, and component 6. The filter information is a string consisting of a single component (component 2). The component information in the terminal identifier can include all the information of the filter information (component 2), and the filter information does not contain any components that are not present in the terminal identifier. In this case, the filter information is matched by the terminal identifier.

[1028] like Figure 9 As shown, the terminal identifier includes the following component information: component 1, component 2, component 3, component 4, component 5, and component 6. The filter information is a string composed of two components (component 2 and component 3). At this time, the filter information is a string. The components in the terminal identifier can include all the information of the filter information (component 2 and component 3), and the filter information does not contain any components that do not exist in the terminal identifier. At this time, the filter information is matched by the terminal identifier.

[1029] The filter information may also include multiple strings, where each string consists of one or more consecutive components. For example... Figure 10As shown, the terminal identifier includes the following component information: component 1, component 2, component 3, component 4, component 5, and component 6. The filter information includes two strings: string1 and string2. Each string consists of one component; string1 consists of component 2, and string2 consists of component 5. The components in the terminal identifier can include all the information in the filter information (components 2 and 5), and the filter information does not contain any components that are not present in the terminal identifier. In this case, the filter information is matched by the terminal identifier.

[1030] When a response to the paging is determined or a match with the filter information is determined, a paging response is sent to the second communication device or the first communication device. The paging response includes an operation response (such as an inventory response). The paging response or operation response includes the terminal identifier of the terminal device.

[1031] Step 5: The reader sends the execution result of the first operation to the first communication device (such as AIoT function), and the execution result carries the terminal identifier.

[1032] Step 6: The first communication device (such as an AIoT function) determines one of the following based on the terminal identifier: authentication device, data management device.

[1033] Step 7a: Optionally, the first communication device (such as an AIoT function) sends a request to the fourth communication device (data management device) to obtain the profile information of the terminal device. Optionally, the request to obtain the profile information includes a terminal identifier. The profile information of the terminal device includes at least one of the following: information for indexing, identifying, or indicating authentication devices, fourth information, the terminal device's certificate, etc., which will not be elaborated further here.

[1034] Step 7b: The fourth communication device returns the profile information of the terminal device.

[1035] Step 8a: The first communication device (such as the AIoT function) sends a terminal identifier to the authentication device (such as the Authentication server function (AUSF) or Authentication Authorization Accounting (AAA)) to request authentication of the first object.

[1036] Step 8b: The authentication device (AUSF or AAA server) authenticates the first object.

[1037] Step 8c: The authentication device (AUSF or AAA server) sends the authentication result of the first object to the first communication device (such as the AIoT function).

[1038] For a terminal device that has passed authentication, the first communication device continues to operate the terminal device (e.g., by sending commands through the second communication device), or the first communication device returns the operation result to the fifth communication device. In one embodiment, only terminal devices that have passed authentication or successfully completed the operation are returned as the operation result.

[1039] This application provides a communication device. As an example, the communication device may be a communication equipment or a component within a communication equipment, such as a chip.
