[0002] This application claims priority to Chinese Patent Application No. 202411585338.8, filed in China on November 7, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of wireless communication technology, specifically relating to an operation execution method, apparatus, communication device, and readable storage medium. Background Technology

[0004] 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.

[0005] AIoT devices communicate with the network through a first communication device (such as a user equipment (UE) or a reader / writer). The first communication device (such as a reader / writer) and the network may support multiple interaction methods. How to achieve communication between the first communication device and the network in scenarios that support multiple interaction methods is a problem that needs to be solved.

The following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to systems other than NR systems, such as 6th generation (6G) radio systems. th Generation 6G communication system.

[0177] The protocol stack types corresponding to the interaction between the reader (such as UEreader) and the network include the following:

[0178] As shown in Figure 1a, this is the protocol stack corresponding to the user plane UP mode. Under this protocol stack, it can be assumed that the UEreader and the network use the UP mode to exchange second information.

[0179] The second information includes at least one of the following: AIoT protocol, AIoT protocol message, information related to AIoT service, information related to AIoT operation or third operation, and control information of the reader / writer.

[0180] The fifth piece of information includes at least one of the following: information for selecting a reader / writer, and information for allocating reader / writer resources.

[0181] The protocol stack for RRC mode is shown in Figure 1b or Figure 1c.

[0182] As shown in Figure 1b, this is the protocol stack corresponding to the first RRC mode. Under this protocol stack, it can be assumed that the UEreader and the network interact using an RRC mode. There is a peer protocol layer (such as the AS layer) corresponding to the second information between the UEreader and the access network device.

[0183] As shown in Figure 1c, this is the protocol stack corresponding to the second RRC method. Under this protocol stack, it can be assumed that the UEreader and the network interact using another RRC method. There is a peer protocol layer (such as the AS layer) corresponding to the second information between the UEreader and the access network device.

[0184] The protocol stack for NAS is shown in Figure 1d or Figure 1e.

[0185] As shown in Figure 1d, this is the protocol stack corresponding to the first NAS method. Under this protocol stack, it can be assumed that the UEreader and the network interact in a NAS method. There is a peer protocol layer (such as the NAS layer) corresponding to the second information between the UEreader and the AMF.

[0186] As shown in Figure 1e, this is the protocol stack corresponding to the second NAS method. Under this protocol stack, it can be assumed that the UEreader and the network interact using another NAS method. There is a peer protocol layer (such as a NAS layer) corresponding to the second information between the UEreader and the AIoT function.

[0187] Examples of CP methods are shown in at least one of the following: Figure 1b, Figure 1c, Figure 1d, Figure 1e, Figure 1f, Figure 1g.

[0188] As shown in Figure 1f, the protocol stack corresponding to the first CP mode is as follows: there is a peer protocol layer (such as the NAS layer) corresponding to the second information between the UEreader and the AMF. There is a peer protocol layer (such as the AS layer) corresponding to the fifth information between the UEreader and the access network device.

[0189] As shown in Figure 1g, the protocol stack corresponding to the second CP method is as follows: there is a peer protocol layer (such as the NAS layer) corresponding to the second information between the UEreader and the AIoT function. There is a peer protocol layer (such as the AS layer) corresponding to the fifth information between the UEreader and the access network device.

[0190] As shown in Figure 1f or Figure 1g, under this protocol stack, the UEreader and the network can be considered to interact using a combination of RRC and NAS methods.

[0191] Question 1:

[0192] Based on the above multiple interaction methods, the first communication device (such as UE) directly or indirectly interacts with the AIoT function to exchange information related to AIoT operations (inventory, read, write, deactivate, activate) (referred to as target information). The interaction of target information resides at different protocol layers, and the requirements for the capabilities of the first communication device (such as UE) and the network are different. Therefore, negotiating the capabilities of the first communication device (such as UE) and the network, and selecting the appropriate interaction method, are problems that need to be solved.

[0193] Question 2:

[0194] The questions of how to select the interaction method and whether to select or authorize the first communication device (such as UE) as the reader / writer also need to be addressed in scenarios with multiple interaction methods.

[0195] When the network supports multiple interaction methods A and the terminal supports interaction method B, if A includes B, then one interaction method supported by both the network and the terminal is selected for communication, and the first communication device (such as UE) is selected as the reader. If A does not include B, then the first communication device (such as UE) is not selected as the reader.

[0196] If both the terminal and the network support multiple interaction methods, the network needs to select one interaction method and send it to the first communication device (such as the UE), and can also send it to the access network device.

[0197] Question 3:

[0198] RRC primarily relies on the interaction between the primary communication device and the access network device. Signaling negotiation between the primary communication device (e.g., UE) and the core network device may not be possible, requiring assistance from the access network device. For example, the primary communication device sends RRC capabilities to the access network device, which then informs the core network device.

[0336] In one embodiment, the active signal generation refers to the terminal device generating a signal itself.

[0337] Alternatively, the second interface can be implemented in the following manner:

[0338] 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 information element (IE) to the mandatory information of the NG interface.

[0339] 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).

[0340] Method 3: Introduce a new interface, such as the second NG interface.

[0341] 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.

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.

[0345] 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.

[0346] 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 determined only after the terminal device provides its identifier. 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 in the third operation).

[0347] 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".

[0348] 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".

[0349] 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.

[0350] 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.

[0351] Optionally, the object requesting the third 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 third operation.

[0353] 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.

[0354] In one implementation, the AIoT service enables customers, networks, or readers to perform operations on terminal devices (such as third operations).

[0355] In one implementation, the supported service areas differ from the TA list supported by the RAN device in related technologies. 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 the NG interface request message in related technologies) can be understood as the first TA, and the supported service areas as the second TA. When the RAN device simultaneously supports communication with the UE and communication with the terminal device, 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 device supports communication with the terminal device, it can provide the second TA list. That is, the information used to indicate the supported service areas can be the second list.

[0356] 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.

[0357] 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.
