For another example, the number of description objects is not limited by the ordinal number and can be one or more. Taking "first device" as an example, the number of "devices" can be one or more. In addition, the objects modified by different prefixes can be the same or different. For example, if the description object is "device", then the "first device" and the "second device" can be the same device or different devices, and their types can be the same or different; for another example, if the description object is "information", then the "first information" and the "second information" can be the same information or different information, and their contents can be the same or different.

[0206] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0208] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0209] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0211] Alternatively, to enable battery-free IoT communication, a new low-power Ambient Internet of Things (A-IoT) device has been introduced. This new A-IoT device does not require batteries, nor does it need to generate its own energy. Instead, it can harvest energy from the outside world, such as from the surrounding environment or signals sent by surrounding devices, and can communicate based on the harvested energy.

[0212] Optionally, the above-mentioned A-IoT device can specifically communicate with the terminal and / or network device based on the energy collected from the outside world. For example, in some embodiments, the terminal and / or network device can send a signal to the A-IoT device. After the A-IoT device receives the signal, it can send corresponding response information to the terminal and / or network device or perform corresponding operations. Among them, when the A-IoT device sends the response information to the terminal and / or network device, it can use a backscatter working mode to send the response information or it can use an active sending working mode to send the response information. Optionally, the above-mentioned "backscatter working mode" can be, for example: the terminal and / or network device first sends an electromagnetic wave / continuous wave (CW) signal to the A-IoT device, and the A-IoT device adjusts the matching between the receiving antenna and the impedance according to the information to be sent, enhances the reflection of the incident CW signal, and modulates the perception data obtained by itself onto the reflected signal to complete the transmission of the data. Optionally, the above-mentioned "active transmission working mode" can be understood as, for example: actively generating signals and actively sending signals without CW signal excitation, wherein the A-IoT device can actively generate signals and actively send signals based on its stored energy, and the energy stored in the A-IoT device can be the energy that the terminal and / or network device pre-charges the A-IoT device.

[0213] Optionally, the aforementioned A-IoT devices may include multiple different types of devices, such as a first type A-IoT device, a second type A-IoT device, and a third type A-IoT device, wherein different types of A-IoT devices correspond to different capabilities.

[0214] Optionally, the above-mentioned first type A-IoT device has energy storage capability, but does not have independent signal generation and amplification capabilities, and its uplink transmission relies on backscatter transmission; that is, the first type A-IoT device needs to use the backscatter working mode to send signals to the terminal and / or network device (such as the aforementioned response information), which has the lowest complexity and cost and very low power consumption.

[0215] Optionally, the above-mentioned second type A-IoT device has energy storage capability and independent signal amplification capability, and its uplink transmission relies on backscatter transmission; that is, the second type A-IoT device can use the backscatter working mode to send signals to the terminal and / or network device, and at the same time can also amplify the power of the sent signal.

[0216] Optionally, the above-mentioned third type A-IoT device has energy storage capability and independent signal amplification capability, and its uplink transmission can be transmitted based on internally generated signals; that is, the third type A-IoT device can actively send signals to the terminal and / or network device based on the internally generated signals.

[0217] Alternatively, the device types of the aforementioned A-IoT devices can be "backscatter" and "non-backscatter," where "backscatter" can, for example, refer to sending signals based on backscattering, and "non-backscatter" can, for example, refer to actively sending signals. It should be noted that the aforementioned device types are merely examples, and other naming formats for device types may exist, which are not specifically limited in this disclosure.

[0218] Optionally, the above-mentioned A-IoT device can be applied to a variety of different communication architectures in the communication system, wherein Figures 1B to 1F are schematic diagrams of the architecture of the A-IoT device during communication according to an embodiment of the present disclosure.

[0219] Optionally, as shown in FIG1B , data can be directly received and sent between an A-IoT device (ie, the Ambient IoT device in FIG1B ) and a network device (eg, a base station (BS)).

[0220] Optionally, as shown in FIG1C , data can be received and sent indirectly between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, where the intermediate node can be, for example, a relay, an integrated access backhaul (IAB) device, a terminal, or a repeater.

[0221] Optionally, as shown in FIG1D , uplink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and downlink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, which can be, for example, a relay, an IAB device, a terminal, or a repeater.

[0222] Optionally, as shown in FIG1E , downlink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and uplink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node.

[0223] Optionally, as shown in FIG1F , data can be directly received and sent between the A-IoT device and the terminal (or user equipment (UE)). The terminal can be responsible for collecting data from the A-IoT device and forwarding the collected data to the network device.

[0224] Optionally, in some embodiments, the network devices, terminals, and intermediate nodes in Figures 1B-1F can be collectively referred to as Readers, and in some embodiments, the Reader will send an Inventory instruction to the A-IoT device to inventory the A-IoT device. Optionally, the inventory instruction can also be called an inventory instruction or a query instruction (query) or a polling instruction, etc., and the present disclosure does not make specific limitations on this. In addition, Figure 1G is a schematic diagram of the inventory process between the Reader and the A-IoT device according to an embodiment of the present disclosure. As shown in Figure 1G, the Reader will first send a query instruction to the A-IoT device, and the instruction carries a numerical value Q. After the A-IoT device receives the query instruction, it will generate an initial random number RN16 based on the numerical value Q in the instruction, where RN16 can be between 0 and 2 QAnd, in some embodiments, the Reader will send queryrep instructions to the A-IoT device multiple times, and after the A-IoT device generates RN16, it will reduce RN16 by one each time it receives a queryrep instruction until RN16 is reduced to 0. The A-IoT device will send the initial random number RN16 generated based on the value Q to the Reader. After receiving the initial random number RN16, the Reader will reply with an acknowledgment (ACK) to the A-IoT device. The ACK carries the initial random number RN16. After receiving the ACK, the A-IoT device will continue to reply to the Reader with the electronic product code (Electronic Product Code) of the A-IoT device. Code, EPC) or XPC code or PC code, and, after the Reader receives the EPC code or XPC code or PC code sent by the A-IoT device, the Reader will send a Req_RN message to the A-IoT device. The Req_RN message may carry the initial random number RN16 or the EPC code or XPC code or PC code. The Req_RN message is used to request the handle of the A-IoT device. The handle can be a random number similar to RN16. For example, after the A-IOT device receives the query instruction, the handle generated based on the Q in the instruction can be 0 to 2 Q The random number selected between the two is used for communication authentication between the Reader and the A-IoT device during subsequent communications. After receiving the Req_RN message from the Reader, the A-IoT device sends the Reader a handle. This handle can also be named differently and is not specifically limited in this disclosure. Subsequently, the Reader can use this handle for communication authentication when communicating with the A-IoT device.

[0225] Optionally, in some embodiments, the Reader may also send a queryadjust command (or queryadjust instruction) to the A-IoT device to adjust the Q value. For example, the queryadjust command may indicate Q+1 or Q-1 or Q remains unchanged, or the queryadjust command may directly indicate a new Q value.

[0226] However, for the above process, frequent interactions are required between A-IoT devices and Readers, which greatly increases the complexity of communication and the complexity of A-IoT device implementation. Therefore, how to simplify the above inventory process is a technical problem that needs to be urgently solved in the A-IOT scenario.

[0227] Based on this, the present disclosure provides a communication method to solve the above technical problems.

[0228] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0229] Step 2101: A first device sends a first instruction to at least one second device.

[0230] Optionally, the first device may be a device that communicates with the second device. For example, the first device may be a network device, such as a base station or a reader, and the second device may be an ambient IoT device. In some embodiments, the second device may be the A-IoT device described in the preceding embodiment of FIG. 2A. In some embodiments, the second device may also be referred to as a low-power device, a low-power ambient IoT device, an A-IoT device, an A-IoT UE, an A-IoT terminal, an A-IoT Tag, etc., which is not specifically limited in this disclosure. Furthermore, the relevant introduction to the A-IoT device has been described in detail in the preceding embodiment of FIG. 2A and will not be repeated here.

[0231] Optionally, in some embodiments, the first device may be at least one of the network devices, terminals, and intermediate nodes shown in Figures 1B-1F. Optionally, in some embodiments, the first device may be called a Reader or other name, which is not specifically limited in this disclosure.

[0232] It should be understood that the first device sending the first instruction to the second device is not limited to the first device qualitatively sending the first instruction to one or more second devices. In some embodiments, the first device may send the first instruction, for example, by broadcasting, and one or more second devices may be the target of the first instruction. Accordingly, the second devices that are the recipients of the first instruction may perform corresponding operations according to the instructions of the first instruction.

[0233] Optionally, the first instruction can be used to perform an inventory of the second device; the first instruction can be an inventory instruction, or can also be called an inventory instruction, a query instruction, or a polling instruction, etc., which is not specifically limited in this disclosure. For example, the first instruction can be, for example, a query instruction, a queryadjust instruction, or a queryrep instruction. The first instruction can carry a first numerical value Q, and the first numerical value Q can be used to generate a random number. For a detailed introduction to "query, queryadjust, queryrep, Q", please refer to the prior art, and this disclosure will not elaborate on this.

[0234] Furthermore, in some embodiments, the first device typically sends the first instruction to at least one second device multiple times.

[0235] Step 2102: The second device sends first information and a first identifier to the first device.

[0236] Upon receiving the first instruction from the first device, the second device may respond to the first instruction. For example, the second device may send a response message to the first device, where the response message may include, for example, the first information and the first identifier. In some embodiments, the second device sends the first information and the first identifier to the first device.

[0237] Of course, it should be understood that the second device may also send the first information and the first identifier to the first device independently of the first instruction. That is, in some embodiments, step 2101 is optional, and the execution of step 2102 is not based on step 2101. The second device may send the first information and the first identifier to the first device without receiving the first instruction.

[0238] Optionally, the first information may be a random number generated by the second device. Optionally, the first information may be a random number generated by the second device based on the first value Q. For example, the first information may be a random number between 0 and 2. Q The random number selected between the first and second instructions may be a random number selected between the first and second instructions, or other generation methods may be used, which are not specifically limited. It should be understood that the second device may determine the first numerical value Q based on the first instruction, or may determine the first numerical value Q in other ways, such as through a protocol agreement, obtaining from other devices, or self-determination. In addition, the first information may be, for example, RN16 or other names described in the previous content of the embodiment of Figure 2A, which is not specifically limited in this disclosure.

[0239] Optionally, the first identifier described above can be used to identify the second device. The first identifier can be, for example, a device identifier, a unique identifier, or a tag identifier of the second device, and this disclosure does not specifically limit this. Furthermore, in some embodiments, the first identifier can be, for example, the EPC code, XPC code, or PC code described above in the embodiment of FIG. 2A , or can be another identifier of the second device, and this disclosure does not specifically limit this.

[0240] In some embodiments, the first information and the first identifier may be carried in the same message. That is, the first information and the first identifier are not sent separately, thereby significantly saving communication steps, improving communication efficiency, and avoiding frequent interactions between the first device and the second device, thereby saving communication resources. Of course, it is also possible to send the first information and the first identifier separately.

[0241] Furthermore, in some embodiments, the method for the second device to send the first information and the first identifier to the first device may include, for example, when the second device receives the first instruction sent by the first device, initially generating the first information based on the first numerical value Q carried in the first instruction, and then, each time the second device receives the first instruction, decrementing the first information by one until the first information is decremented to 0, at which point the second device sends the first identifier and the first information initially generated based on the first numerical value Q to the second device. In other words, the first instruction may include the first numerical value Q.

[0242] For example, it is assumed that after the second device receives the first instruction, it initially generates the first information based on the first value Q carried in the first instruction: a first random number, such as X, where X can be the aforementioned number between 0 and 2. Q Then, each time the second device receives the first instruction, it will reduce the first random number by one until the first random number is reduced to 0. The second device will send the first identifier and the first random number it initially generated, such as X, to the first device.

[0243] Furthermore, in some embodiments, the purpose of the second device sending the first information and the first identifier to the first device in this step 2102 can, for example, be to implement a preliminary handshake between the first device and the second device, so that the first device and the second device can further perform a subsequent handshake process based on the first information and the first identifier.

[0244] Step 2103: The first device sends a first request to the second device.

[0245] Optionally, the first request may include the above-mentioned first information and / or first identifier. In some embodiments, the first request may include the above-mentioned first information. In some embodiments, the first request may include the above-mentioned first identifier. In some embodiments, the first request may include the above-mentioned first information and first identifier. And, the first request may be used to request the second information. In some embodiments, by including the first information and / or first identifier in the first request, when the second device receives the first request, if it is determined that the first information and / or first identifier included in the first request is its own first information and / or first identifier, the first device may determine that the first request is a request for the second information from itself. Otherwise, if the first device determines that the first request is not a request for the second information from itself, the first request may be ignored. Optionally, the first request may be called RN_Req or other names, for example, and this disclosure does not specifically limit this.

[0246] Optionally, in some embodiments, the second information can be used to perform communication authentication between the first device and the second device. For example, the second information can be used to implement communication authentication between the first device and the second device during the process of the first device sending a first command to the second device. Specifically, when the first device is to send a first command to the second device, the second information can be carried in the first command, and the first command can be used to instruct the execution of a first operation. After the second device receives the first command, it can determine that the first command is sent to itself by the first device by querying the second information in the first command, so that the second device can perform the corresponding first operation based on the first command. And, when the second device returns the operation result to the first device after executing the first operation, the second information can also be carried in the operation result. After the first device receives the operation result, it can determine that the operation result is the operation result of the second device based on the second information carried in the operation result, thereby implementing communication authentication between the first device and the second device.

[0247] Optionally, in some embodiments, the second information may be a random number of shorter length. Thus, when the above-mentioned communication authentication is performed based on the second information, fewer communication resources are required due to the shorter length of the second information, thereby greatly reducing communication overhead and saving communication resources.

[0248] Optionally, the second information may be the handle or other names described above in the embodiment of FIG. 2A , and this disclosure does not specifically limit this.

[0249] Optionally, the first command may include at least one of the following:

[0250] Read command;

[0251] Write command;

[0252] Terminate the kill command;

[0253] Lock the lock command.

[0254] Optionally, the first command may also include other commands, such as a command for a specific second device, which is not detailed in this disclosure.

[0255] It can be seen from the above content that in the embodiment of the present disclosure, the process of the first device (i.e., Reader) requesting the second information (i.e., handle) from the second device (i.e., A-IoT device) is mainly as follows: the first device first sends a first instruction (i.e., query instruction), and after the second device receives the first instruction, it sends the first information (i.e., RN16) and the first identifier (i.e., EPC code or XPC code or PC code) to the first device. Afterwards, the first device sends a first request (i.e., RN_Req) ​​to the second device based on the first information and / or the first identifier to request the second information. In the prior art, the process of the Reader requesting a handle from the A-IoT device is as follows: the Reader sends a query command to the A-IoT device, and after receiving the query command, the A-IoT device sends RN16 to the Reader. The Reader then sends an ACK command to the A-IoT device, and the ACK command carries RN16. After receiving the ACK command, the A-IoT device sends an EPC code, XPC code, or PC code to the Reader. Only after receiving the EPC code, XPC code, or PC code will the Reader send RN_Req to the second device to request a handle. By comparison, it can be seen that the method disclosed in the present invention combines the two steps of "A-IoT device sends RN16 to Reader" and "A-IoT device sends EPC code or XPC code or PC code to Reader" in the process of the prior art into one step, and omits the step of "Reader sends ACK command to A-IoT device", that is: after Reader receives RN16 and EPC code or XPC code or PC code sent by A-IoT device, Reader no longer needs to send ACK command, but directly sends RN_Req to A-IoT device to request handle, thereby omitting the ACK transmission process, simplifying the communication steps, improving communication efficiency, and saving communication resources.

[0256] Step 2104: The second device generates second information.

[0257] Optionally, the second device may generate second information based on the first value Q. The method for generating the second information is similar to the method for generating the first information, and is not further described here. In some embodiments, the second information may be the same as or different from the first information.

[0258] It should be noted that, in some embodiments, the second device may generate the second information after receiving the first instruction in the above step 2101. Alternatively, in other embodiments, the second device may generate the second information between receiving the first instruction and receiving the first request. Alternatively, in still other embodiments, the second device may generate the second information after receiving the first request.

[0259] Step 2105: The second device sends second information to the first device.

[0260] For a detailed introduction to the second information, please refer to the above step description.

[0261] Step 2106: The first device and the second device perform communication authentication based on the second information.

[0262] For a detailed introduction on how to perform communication authentication based on the second information, please refer to the aforementioned step description.

[0263] In the above embodiment, after the first device sends the first instruction to the second device, it will receive the first information and / or first identifier sent by the second device. Afterwards, the first device can send a first request to the second device based on the first information and / or first identifier of the second device to request the second information, and receive the second information sent by the second device. The second information can be used for communication authentication between the first device and the second device. In the above process, the first device and the second device can determine the second information for communication authentication through a few simple interactions without frequent interactions. Compared with the process of the prior art, the communication steps are greatly simplified, and the complexity of the implementation of the second device (i.e., the environmental Internet of Things device) is also reduced, saving communication time and communication resources, and improving communication efficiency.

[0264] The communication method according to the embodiment of the present disclosure may include at least one of steps 2101 to 2106. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, and steps 2101+2102 may be implemented as independent embodiments, but are not limited thereto.

[0265] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0266] FIG2B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0267] Step 2201: A first device sends a first instruction to at least one second device.

[0268] For a detailed introduction to the first device, the second device, and the first instruction, please refer to the above embodiment description.

[0269] Step 2202: The second device sends a first identifier to the first device.

[0270] For details on receiving the first identifier, please refer to the description in the above embodiment.

[0271] Upon receiving the first instruction from the first device, the second device may respond to the first instruction. For example, the second device may send a response message to the first device, where the response message may be, for example, the first identifier. In some embodiments, the second device sends the first identifier to the first device.

[0272] Of course, it should be understood that the second device may also send the first identifier to the first device independently of the first instruction. That is, in some embodiments, step 2201 is optional, and the execution of step 2202 is not based on step 2201. The second device may send the first identifier to the first device without receiving the first instruction.

[0273] Optionally, in some embodiments, the method for the second device to send the first identifier to the first device may include, for example, generating a random number based on a first value Q carried in the first instruction when the second device receives the first instruction sent by the first device. Thereafter, each time the second device receives the first instruction, it decrements the random number by one until the random number reaches 0, at which point the second device sends the first identifier to the second device. For details on how to generate a random number based on Q, refer to the description of the above embodiment.

[0274] Step 2203: The first device sends a first request to the second device.

[0275] Optionally, the first request may include the above-mentioned first identifier, and the first request may be used to request the second information. In some embodiments, by including the first identifier in the first request, when the second device receives the first request, if it is determined that the first identifier included in the first request is its own first identifier, the first device may determine that the first request is a request for the second information from itself. Otherwise, if the first device determines that the first request is not a request for the second information from itself, it may ignore the first request. Optionally, the first request may be called, for example, RN_Req or other names, which is not specifically limited in this disclosure.

[0276] Also, for a detailed description of step 2203, please refer to the above embodiment description.

[0277] Step 2204: The second device generates second information.

[0278] Step 2205: The second device sends second information to the first device.

[0279] Step 2206: The first device and the second device perform communication authentication based on the second information.

[0280] For a detailed description of steps 2204-2206, please refer to the above embodiment description.

[0281] It can be seen from the above steps 2201-2206 that in the process of determining the second information, after the second device receives the first instruction sent by the first device, it is no longer necessary to send the first information to the first device, but directly sends the first identifier to the first device. After that, the first device can directly send a first request to the second device based on the first identifier to request the second information, and the second device can send the second information to the first device based on the first request. Compared with the existing process, in the method disclosed in the present invention, the second device does not need to send RN16 to the first device, and the first device does not need to send an ACK command to the second device, so the transmission process of RN16 and ACK is omitted, thereby simplifying the communication steps between the first device and the second device, improving communication efficiency, and saving communication resource overhead.

[0282] In the above embodiment, after the first device sends the first instruction to the second device, it will receive the first identifier sent by the second device. Thereafter, the first device can send a first request to the second device based on the first identifier of the second device to request the second information, and receive the second information sent by the second device. The second information can be used for communication authentication between the first device and the second device. In the above process, the first device and the second device can determine the second information for communication authentication through a few simple interactions without frequent interactions. Compared with the process of the prior art, the communication steps are greatly simplified, and the implementation complexity of the second device (i.e., the environmental Internet of Things device) is also reduced, saving communication time and communication resources, and improving communication efficiency.

[0283] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2201 to 2206. For example, step 2201 may be implemented as an independent embodiment, step 2202 may be implemented as an independent embodiment, and steps 2201+2202 may be implemented as independent embodiments, but are not limited thereto.

[0284] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0285] FIG2C is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2C , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0286] Step 2301: A first device sends a first instruction to at least one second device.

[0287] Step 2302: The second device sends a first identifier to the first device.

[0288] For a detailed description of steps 2301 - 2302 , please refer to the above embodiment.

[0289] Step 2303: The first device generates second information.

[0290] Optionally, after the first device receives the first identifier sent by the second device, the first device may generate second information. This second information may be, for example, information assigned by the first device to the second device for communication authentication, or may be a random number generated by the first device. In some embodiments, the method by which the first device generates the second information may be the same as or different from the method by which the second device generates the second information, and this disclosure does not specifically limit this.

[0291] Also, for a detailed introduction to the second information, please refer to the above embodiment description.

[0292] Step 2304: The first device sends a first message to the second device.

[0293] Optionally, the first message may be ACK.

[0294] Optionally, the first message may include second information and a first identifier, and when the second device receives the first message, if the first identifier in the first message is its own identifier, it determines that the second information in the first message is information assigned to itself; otherwise, it determines that the first message is not sent to itself, and the first message can be ignored.

[0295] Step 2305: The first device and the second device perform communication authentication based on the second information.

[0296] For a detailed description of steps 2304-2305, please refer to the above embodiment description.

[0297] It can be seen from the above steps 2301-2305 that in the process of determining the second information, the second device no longer needs to send the first information to the first device, and the second information is directly generated by the first device and indicated to the second device. There is no need for the first device to request the second information from the second device, which greatly reduces the communication steps, improves communication efficiency, and saves communication resource overhead.

[0298] In the above embodiment, after the first device sends the first instruction to the second device, it will receive the first identifier sent by the second device. Thereafter, the first device can directly determine the second information and indicate the second information to the second device. The second information can be used for communication authentication between the first and second devices. In the above process, the first and second devices can determine the second information used for communication authentication through a few simple interactive steps, without the need for frequent interaction. Compared with the process of the prior art, this greatly simplifies the communication steps, reduces the complexity of the second device (i.e., the environmental IoT device), saves communication time and communication resources, and improves communication efficiency.

[0299] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2301 to 2305. For example, step 2301 may be implemented as an independent embodiment, step 2302 may be implemented as an independent embodiment, and steps 2301+2302 may be implemented as independent embodiments, but are not limited thereto.

[0300] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0417] FIG5 is an interactive diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG5 , the present disclosure embodiment relates to a communication method for use in a communication system including a first device and a second device, wherein the method includes at least one of the following:

[0418] Step 5101: The first device sends a first instruction to the second device;

[0419] Step 5102: The second device receives the first instruction sent by the first device.

[0420] Step 5103: The second device sends first information and / or a first identifier to the first device.

[0421] Step 5104: The first device receives the first information and / or first identifier sent by the second device.

[0422] Step 5105: The first device determines second information based on the first information and / or the first identifier.

[0423] Step 5106: The second device determines the second information.

[0424] Optional implementations of steps 5101 to 5106 can be found in the above embodiments.

[0425] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0426] The communication method involved in the embodiment of the present disclosure may include at least one of steps 5101 to 5106. For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0427] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0428] The following is an exemplary introduction to the above method.

[0429] Optional embodiment 1: The tag sends the RN16 and EPC code together to the reader. The reader replies with the RN_Req command to the tag, and the tag replies with the handle to the reader.

[0430] Example: The EPC code is the tag's identifier or unique identifier, which can also be called a tag identifier or have other names. RN16 is a random number generated by the tag based on Q. For example, it is a random number selected between 0 and 2 to the power of Q. There may also be other ways to generate random numbers based on Q, which are not limited. The tag sends RN16 and the EPC code to the Reader together. The Reader determines that it has received the tag's RN16 and EPC code, and the reader replies with a RN_Req command (omitting the ACK command). The RN_Req command carries the tag's RN16 and / or EPC code, and the tag replies with a handle to the reader. The handle is a random number generated based on Q similar to RN16. The handle serves as an identifier for subsequent read, write, kill, lock and other commands between the tag and the reader.

[0431] Optional embodiment 2: The tag sends the EPC code to the reader. The reader replies with an RN_Req command to the tag, and the tag replies with a handle to the reader.

[0432] Example: The tag sends the EPC code to the reader. The reader confirms receipt of the tag's EPC code and responds with an RN_Req command (omitting the ACK command). This RN_Req command carries the tag's EPC code and the tag returns a handle to the reader. The handle is a random number generated based on Q similar to the RN16. This handle serves as an identifier for subsequent read, write, kill, lock, and other commands between the tag and reader.

[0433] Optional embodiment 3: The tag sends the EPC code to the reader. The reader replies with an ACK command to the tag, and the ACK command carries a handle.

[0434] Example: The tag sends the EPC code to the reader. The reader confirms that it has received the tag's EPC code and replies with an ACK command. The ACK command carries the tag's EPC code and a handle (which can be named differently). This handle is assigned by the reader to the tag, illustratively similar to the random number generated by RN16 based on Q. This handle serves as an identifier for subsequent read, write, kill, lock, and other commands executed between the tag and reader.

[0435] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0436] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device.
