[0122] "question"

[0123] In this application embodiment, the following problems need to be solved:

[0124] The identifier of a terminal device (such as an AIoT device) can be an identifier assigned by the operator or by a third party. In addition to being used to find and authenticate devices, it is also used to uniquely identify the terminal device or to identify the data management device (the device that stores the terminal device's data (such as a UDM, UDR) or the device that stores third-party context).

[0125] Question 1: What information can be used to identify a data management device? What information is stored in the data management device?

[0126] For the identifier assigned by a third party, if the information of the third party can identify the data management device, then the data of the terminal device in the data management device may include: information used to identify the authentication device.

[0127] 1) For example, a terminal identifier assigned by a third party carries information about that third party, but this information may not necessarily be used to identify the authentication device. In this case, the third party's information can be used to index the data management device.

[0128] The data management device can be identified using information from a third party. The information stored by the data management device per terminal device may include information about the terminal device's authentication device. Alternatively, the context stored by the data management device per third party may include information about the authentication device.

[0129] 2) For example, the terminal identifier assigned by the operator carries network identifier information. The network identifier may or may not be used to identify the authentication device. However, the network identifier can be used to identify the data management device.

[0130] 3) For example, in type example 7, it is unclear which information is used to locate the data management device, such as the terminal identifier EPC, TID, or other type. The AF can specify the information used to determine the authentication device or the data management device.

[0131] The terminal identifiers with network identifiers can be shown in Table 1 below:

[0132] Table 1:

[0133] For terminals without a network identifier, the identifiers are shown in Table 2 below:

[0134] Table 2:

[0135] One solution is to identify the data management device using at least one of the following: network identifier and third-party information. Alternatively, the information used to identify the data management device may include at least one of the following: network identifier and third-party information.

[0136] Terminal device identifiers are diverse and may exist in multiple types; the information contained in the ID types is still insufficient:

[0147] In one embodiment, the Credential Holder information is an example of information used to index, identify, or indicate authentication devices. This is merely an illustrative example of the Credential Holder. In one embodiment, the Credential Holder in this application may be replaced with information used to index, identify, or indicate authentication devices.

[0148] Type 3B: Network identifier + third-party information (e.g., when the network identifier is not used to indicate a Credential Holder) + TID;

[0149] Type 3C: Network identifier + third-party information (e.g., when the network identifier is not used to indicate the Credential Holder) + third identifier.

[0150] In some implementations, the terminal identifier includes the following types:

[0152] Type 4B: Third-party information + credential holder (e.g., when the third-party information is not used to indicate the credential holder) + TID;

[0153] Type 4C: Third-party information + credential holder (e.g., when the third-party information is not used to indicate the Credential Holder) + third identifier.

[0154] In some implementations, the terminal identifier includes the following types:

[0155] Type 5A: Network identifier + credential holder (e.g., when the network identifier is not used to indicate the credential holder) + EPC;

[0156] Type 5B: Network identifier + credential holder (e.g., when the network identifier is not used to indicate the credential holder) + TID;

[0169] Type 8B: Credential holder (e.g., when the network identifier is not used to indicate a Credential Holder) + third identifier.

[0193] In one optional embodiment of this application, the idle or available device identifier includes: a device identifier not bound to subscriber data, and a device identifier not in a registered state. For example, a terminal can use its device identifier to initiate emergency registration. In this case, in one implementation, even if the device identifier is not bound to any subscriber data, the device identifier is considered to be occupied and cannot be bound to subscriber data again. When the device identifier goes to register, the terminal can consider the device identifier to have returned to an idle state.

[0194] In one optional embodiment of this application, the subscriber data may be used for at least one of the following: terminal access to the network, network authentication and / or authorization of terminal access, and network identification of the terminal.

[0209] 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.

[0248] In one implementation, the NEF can support a first AIoT function, and the AMF can support a second AIoT function or an AIoT function.

[0249] In one embodiment of this application, the first operation may also be referred to as an AIoT operation (operation on the terminal device).

[0256] 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.

[0257] The first operation (also referred to as an AIoT operation) may include one or more operations on the terminal device; the terminal device may be one or more terminal devices.

[0258] In one implementation, the first operation (such as an operation performed on a terminal device) includes at least one of the following:

[0260] 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);

[0268] 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)).

[0269] In another implementation, the operation on the terminal device includes at least one of the following:

[0270] 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;

[0271] 2) Positioning operations, including positioning terminal devices;

[0275] 2) Configure information for the terminal device;

[0276] 3) Enable the RF capability of the terminal device;

[0279] 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:

[0280] 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 and CN device (such as AIoT function);

[0281] 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).

[0282] 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.

[0283] 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.

[0284] It should be noted that the information used to request the execution of the first operation (which can be simply referred to as the information used to request the execution of the first operation) may include information about the related operations used to request the execution of the first operation.

[0285] 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 implementation, 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.

[0294] 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:

[0295] - An access device (also known as an AIoT wireless access device or an AIoT wireless access system) supports at least one of the following: communicating with a terminal device, communicating with a 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);

[0296] -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;

[0297] - As an access device for terminal devices to access wireless communication systems;

[0301] 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.

[0302] 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.

[0303] In one embodiment of this application, the reader / writer device may also be referred to as an interrogator device.

[0304] 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.

[0305] 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.

[0306] 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.

[0307] 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.

[0308] 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.

[0309] In one implementation, the second interface includes at least one of the following:

[0310] Unlike the existing NG interface, this is the interface between the RAN and CN.

[0311] The interface between the first communication device (such as "device that supports communication with terminal devices", reader) and the AIoT function;

[0312] The interface between the first communication device (such as "device supporting communication with terminal devices", reader) and the AMF function;

[0313] The interface between the first communication device (such as "device that supports communication with terminal devices", reader) and the core network equipment.

[0314] In one implementation, the device that supports communication with the terminal device is one of the following:

[0315] 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;

[0316] 2) Devices that support communication with terminal devices via wireless interfaces;

[0317] 3) Fourth communication device, such as UDM, UDR, NRF, AIoT function, second AIoT function;

[0318] 4) AIoT functionality, second AIoT functionality;

[0319] 5) First AIoT function: The AIoT function part directly connected to the RAN;

[0320] 6) AMF access management and / or mobility management functions.

[0321] 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.

[0322] In one embodiment, the active signal generation refers to the terminal device generating a signal itself.

[0323] Alternatively, the second interface can be implemented in the following manner:

[0324] 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.

[0325] Method 2: Reuse the NG interface, but for example, if the base station only supports terminal devices (new wireless interface), an instruction can be added to ignore the mandatory IE that already exists but is not applicable to terminal devices, such as the default paging discontinuous reception (Default Paging DRX).

[0326] Method 3: Introduce a new interface, such as the second NG interface.

[0327] In one optional embodiment of this application, 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 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.

[0328] 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).

[0329] 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.

[0330] 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.

[0331] 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.

[0332] 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).

[0333] 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".

[0334] 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".

[0335] 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.

[0336] 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.

[0337] Optionally, the object requesting the first operation refers to the requester (also known as the client). The requester may be a certificate holder (such as the certificate holder of an AIoT device). There may be one or more objects requesting the first operation.

[0338] 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).

[0339] 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.

[0340] 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.

[0341] 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.

[0342] The first communication device (such as a reader / writer) can communicate directly with the terminal device or through an intermediate device. Sometimes, when the first communication device is far from the terminal device, it can extend the reader / writer's coverage area through an intermediate device. In this case, the intermediate device is also called a reader / writer or a component of the reader / writer.

[0343] In one embodiment, the intermediate device may be an intermediate node located between the terminal device 11 and other devices (such as access network devices or readers), but is not limited thereto. The intermediate device may extend the coverage of the other devices or assist communication between the terminal device 11 and other network devices (such as access network devices or readers), but is not limited thereto.

[1014] Example 1: Determining the Authentication Equipment

[1015] As shown in Figure 15, the following steps may be included:

[1016] 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 second communication device.

[1020] The second information corresponding to the third party is stored in the information corresponding to the third party.

[1021] Step 1: The third communication device (such as AF or NEF) requests the first operation from the first communication device.

[1022] Optionally, the request for the first operation may include second information; or, as in step 0, if second information has already been provided, the request for the first operation in step 1 may not include second information.

[1023] The second information may be as described in the above embodiments. For example, the second information includes at least one of the following: information for indexing, identifying or indicating authentication devices, information for indexing, identifying or indicating data management devices, and relevant information of terminal identification, which will not be elaborated here.

[1024] Step 2: The first communication device (such as an AIoT function) sends the relevant information of the first operation to the access device (such as a reader / writer, which will be described as an example below).

[1025] Step 3: The reader / writer pages the terminal device.

[1026] Step 4: The terminal device sends the terminal identifier to the reader.

[1027] The terminal identifier may include first information. Alternatively, the terminal identifier may not include the first information, which is obtained as in step 1. The terminal identifier and the first information may be as described in the above embodiments, for example, the first information may include at least one of the following: network identifier, third-party information, certificate holder or authentication device information, which will not be elaborated further here.

[1028] In one implementation, the second information in the first data of the terminal device within the first communication device or the information corresponding to a third party is directly determined by the terminal identifier.

[1029] In another implementation, the second information is determined directly through the terminal identifier.

[1030] In another implementation, the second communication device is determined by the first information, and then the second information is obtained from the second communication 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 first information in or outside the terminal identifier: an authentication device, used to index, identify or indicate the information of the authentication device.

[1033] Optionally, the first communication device determines the first information in the terminal identifier based on terminal identifier-related information within or outside the terminal identifier;

The second communication device sends the second information.

[1040] It is easy to understand that when the second information is second information at the third-party granularity, or second information within the corresponding third-party information, the second information can be determined through the third-party information. The second communication device then sends the second information.

[1041] It is easy to understand that when the second information is second information at the third-party granularity, or second information in the information corresponding to the third party, and is stored in the second communication device of network A, then the second communication device can be determined first through the network identifier, and then the second information in the second communication device can be determined and / or sent through the third-party information.

[1042] It is easy to understand that when the second information is network-level information, the network identifier can be used to determine and / or send the second information.

[1043] It is easy to understand that when the second information is a combination of network and third-party information, the second information can be determined and / or sent through the network identifier and the third-party information.

[1044] Step 8a: The first communication device (such as the AIoT function) sends the terminal identifier to the second communication device (AUSF or AAA) to request authentication of the first object.

[1045] Step 8b: The second communication device (AUSF or AAA) authenticates the first object.

[1046] The first object can be as described in the above embodiments, and will not be repeated here.

[1047] Step 8c: The second communication device (AUSF or AAA) sends the authentication result of the first object to the first communication device (such as the AIoT function).

[1056] Step 1: The first communication device (such as an AIoT function) receives or locally configures information for indexing, identifying, or instructing the data management device.

[1057] Step 2: The third communication device (such as AF or NEF) requests the first operation from the first communication device.

[1058] Optionally, the request for the first operation may include second information; or, as in step 0, if second information has already been provided, the request for the first operation in step 1 may not include second information.

[1059] Step 3: The first communication device (such as an AIoT function) sends the relevant information of the first operation to the access device (such as a reader / writer, which will be described as an example below).

[1060] Step 4: The reader / writer pages the terminal device.

[1061] Step 5: The terminal device sends the terminal identifier to the reader.

[1063] In one implementation, the second information in the first data of the terminal device within the first communication device or the information corresponding to a third party is directly determined by the terminal identifier.

[1064] In another implementation, the second information is determined directly through the terminal identifier.

[1065] In another implementation, the second communication device is determined by the first information, and then the second information is obtained from the second communication device.

[1066] Step 6: 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.
