Description

Information processing method and device, communication equipment, communication system and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to information processing methods and devices, communication equipment, communication systems, and storage media. Background Art

[0002] Ambient-IoT (Ambient Power Enabled Internet of Things) devices are IoT devices that support ambient power. In specific scenarios, they can be powered by energy from the environment. Compared to narrowband IoT (NB-IoT) devices, Ambient-IoT devices are less complex and less expensive.

[0003] Ambient-IoT devices are generally low-power devices, so they can maintain operation for a long time based on energy from the environment or their own batteries. However, energy is limited. Once the energy is exhausted, the Ambient-IoT device will stop working without further energy from the environment, affecting the user experience.

[0049] Embodiments of the present disclosure provide an information processing method and apparatus, a communication device, a communication system, and a storage medium.

[0050] In a first aspect, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a first device, and the method includes:

[0051] receiving a first instruction sent by a second device;

[0052] Generate a random number according to the first instruction; the random number is used to determine a timing for the first device to send information to the second device;

[0053] If the random number is greater than or equal to a reference threshold, the first device ignores the second instruction sent by the second device.

[0054] In the above embodiment, the first device generates a random number based on the first instruction received from the second device, so that the timing of sending information from the first device to the second device is determined based on the value of the random number. For first devices whose random numbers are greater than or equal to a reference threshold, since these first devices typically need to listen for the second instruction for a long time before sending information to the second device, in order to reduce the situation where these first devices listen for the second instruction for a long time, a reference threshold can be introduced so that first devices whose random numbers are greater than or equal to the reference threshold directly ignore the second instruction sent by the second device, without having to continuously listen for the second instruction, thereby significantly reducing the power consumption of these first devices and improving the battery life of these first devices.

[0055] In combination with some embodiments of the first aspect, in some embodiments, the first instruction carries a first parameter; the first parameter is used by the first device to generate the random number.

[0056] In the above embodiment, the first device receives a first instruction carrying a first parameter sent by the second device, so that the first device generates a random number according to the first parameter configured by the second device; in this way, the numerical range of the random number generated by the first device is limited by the first parameter, so that the second device can configure a suitable reference threshold for the first device according to the numerical range of the random number generated by the first device.

[0057] In conjunction with some embodiments of the first aspect, in some embodiments, the second instruction includes: a third instruction;

[0058] The method further comprises:

[0059] The first device receives the third instruction, and the random number is reduced by 1;

[0060] The random number is equal to a first value, and the first device sends information to the second device.

[0061] In the above embodiment, when the random number is greater than or equal to the reference threshold, the first device may ignore the third instruction sent by the second device, so that the first device whose random number is greater than or equal to the reference threshold does not need to update the value of the random number, so that the first device whose random number is greater than or equal to the reference threshold will neither receive the instruction sent by the second device nor send information to the second device, thereby greatly reducing the power consumption of the terminal.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, the second instruction includes: a fourth instruction;

[0063] The method further comprises:

[0064] According to the fourth instruction, a timing for the first device to send information to the second device is re-determined.

[0065] In the above embodiment, if the random number is greater than or equal to the reference threshold, the first device may ignore the fourth instruction sent by the second device. This eliminates the need for the first device, whose random number is greater than or equal to the reference threshold, to re-determine the timing for sending information to the second device. In this way, the first device, whose random number is greater than or equal to the reference threshold, will neither receive instructions from the second device nor send information to the second device, significantly reducing power consumption of the terminal.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, the first instruction includes: first information;

[0067] The method further comprises:

[0068] The reference threshold is determined according to the first information.

[0069] In the above embodiment, by including the first information in the first instruction, the first device that receives the first instruction can determine the reference threshold configured by the second device for the first device based on the first information. This allows the first device's behavior of receiving or ignoring the second instruction to be controlled to a certain extent by the second device, thereby facilitating the second device's determination of the first device whose random number is greater than or equal to the reference threshold. This also allows the second device to reduce the number of times it sends the second instruction to the first device whose random number is greater than or equal to the reference threshold, thereby facilitating energy conservation for the second device.

[0070] In conjunction with some embodiments of the first aspect, in some embodiments, the first information includes at least one of the following:

[0071] A first information field indicating the reference threshold;

[0072] The second information field carries index information; the index information is used to determine the reference threshold.

[0073] In the above embodiment, by carrying the reference threshold and / or index information in the first information, the first device can determine the reference threshold based on the different information contents carried by the first information; thereby facilitating the second device to determine the first device whose random number is greater than or equal to the reference threshold, so that the second device can also reduce the number of times the second instruction is sent to the first device whose random number is greater than or equal to the reference threshold, which is beneficial for the second device to save energy.

[0074] In conjunction with some embodiments of the first aspect, in some embodiments, the first instruction further includes: timer information;

[0075] The random number is greater than or equal to a reference threshold, and the first device ignores the second instruction sent by the second device, including:

[0076] The random number is greater than or equal to the reference threshold, and the timer is started;

[0077] During the running of the timer, the first device ignores the second instruction sent by the second device.

[0078] In the above embodiment, by carrying the first information and timer information in the first instruction, the first device whose random number is greater than or equal to the reference threshold starts the timer and ignores the second instruction sent by the second device within the time length specified by the second device (i.e., during the operation of the timer), so that the behavior of the first device ignoring the second instruction can be controlled by the second device to a certain extent, so that the first device stops listening to the second instruction during the operation of the timer, and also stops sending the second instruction to the first device whose random number is greater than or equal to the reference threshold during the operation of the timer, which is beneficial to energy saving of the first device and the second device.

[0079] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0080] Determine second information based on the first information; the second information includes one of the following:

[0081] The second parameter is used to determine the timing duration of the timer;

[0082] The third parameter is used by the first device to adjust the value of the random number.

[0083] In the above embodiment, the first device can determine the timing duration of the timer and / or the adjustment value of the random number based on the first information, so that the first device can decode more configuration parameters from the first information without increasing the amount of information carried by the first information.

[0084] In conjunction with some embodiments of the first aspect, in some embodiments, determining the second information based on the first information includes:

[0085] Determine the second information from mapping information according to the index information and / or the reference threshold; wherein the mapping information includes one of the following:

[0086] first mapping information, indicating a mapping relationship between the index information and the second parameter and / or the third parameter;

[0087] second mapping information, indicating a mapping relationship between the reference threshold and the second parameter and / or the third parameter;

[0088] The third mapping information indicates a mapping relationship between the index information, the reference threshold and the second parameter and / or the third parameter.

[0089] In the above embodiment, the first device can select appropriate mapping information based on the different information contents carried by the first information, so as to accurately determine the second information based on the mapping relationship indicated by the mapping information. This is beneficial for reducing the amount of information required to be carried by the first information while ensuring that the first device can decode it correctly.

[0090] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0091] When the timer times out, the first device receives a fifth instruction sent by the second device.

[0092] In the above embodiment, when the timer times out and the first device whose random number is greater than or equal to the reference threshold starts to monitor the instruction sent by the second device, the fifth instruction is used to control the instruction monitoring behavior of the first device after the timer times out.

[0093] In conjunction with some embodiments of the first aspect, in some embodiments, the fifth instruction includes: the second parameter;

[0094] The method further comprises:

[0095] When the timer times out and the first device receives the second parameter, the first device restarts the timer;

[0096] During the running of the restarted timer, the first device continues to ignore the second instruction sent by the second device.

[0097] In the above embodiment, if the timer expires and the first device receives a fifth instruction carrying the second parameter, the first device may restart the timer; during the restarted timer, the second instruction sent by the second device may continue to be ignored. This facilitates the second device using the fifth instruction carrying the second parameter to adjust the time at which the first device begins listening for the second instruction when the random number is greater than or equal to the reference threshold.

[0098] In conjunction with some embodiments of the first aspect, in some embodiments, the fifth instruction includes: the third parameter;

[0099] The method further comprises:

[0100] When the timer times out and the first device receives the third parameter, the third parameter is subtracted from the random number;

[0101] If the random number after subtracting the third parameter is greater than the first value, the first device starts monitoring the second instruction;

[0102] The random number after subtracting the third parameter is less than or equal to the first value, and the first device sends information to the second device.

[0103] In the above embodiment, when the timer expires and the first device receives a fifth instruction carrying a third parameter, the first device can adjust the value of the random number using the third parameter to change the timing at which the first device sends information to the second device. This facilitates the second device dynamically adjusting the timing at which the first device sends information to the second device when the random number is greater than or equal to the reference threshold by sending a fifth instruction carrying a different third parameter.

[0104] In a second aspect, an embodiment of the present disclosure provides an information processing method, which is performed by a second device and includes:

[0105] A first instruction is sent to a first device; the first instruction is used by the first device to generate a random number; the random number is used to determine the timing when the first device sends information to the second device; wherein, if the random number is greater than or equal to a reference threshold, the first device ignores a second instruction sent by the second device.

[0106] In the above embodiment, the second device can send a first instruction to the first device so that the first device generates a random number based on the first instruction, and then determine the timing of the first device sending information to the second device based on the value of the random number. For first devices whose random numbers are greater than or equal to the reference threshold, since these first devices usually need to listen to the second instruction for a long time before sending information to the second device; in order to reduce the situation where these first devices listen to the second instruction for a long time, a reference threshold can be introduced so that first devices whose random numbers are greater than or equal to the reference threshold directly ignore the second instruction sent by the second device, without having to continuously listen to the second instruction, thereby significantly reducing the power consumption of these first devices and improving the battery life of these first devices.

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.

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

[0178] In today's IoT networks, traditional IoT devices are often powered by conventional batteries with limited lifespans, negatively impacting the user experience. The astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of conventional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in some extreme environmental conditions. Battery-free IoT communications have been proposed, promising improved network performance and sustainability, and expanding application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. By eliminating traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

[0179] In the era of the fifth generation of mobile communications (5G), various low power wide area network (LPWA) technologies, such as machine type communication (MTC), narrowband Internet of Things (NB-IoT), reduced capability (RedCap), etc., have been developed to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption and large-scale connectivity, which can meet the requirements of many applications. However, there are still many use cases and applications that cannot be solved in the following situations. First, devices driven by traditional batteries are not applicable, such as in extreme environmental conditions (such as high voltage, extremely high / low temperature, humid environment). Second, maintenance-free devices are required (for example, traditional batteries that do not need to be replaced in the device). Finally, ultra-low complexity, very small device size / form factor (such as mm thickness), longer life cycle, etc. are required.

[0180] Ambient-powered IoT is a promising technology that can address the aforementioned unmet needs. An ambient-powered IoT device is an IoT device powered by energy harvesting, either without a battery or with limited energy storage capabilities (e.g., using capacitors), by harvesting radio waves, light, motion, heat, or any other suitable power source.

[0181] Energy obtained from the environment can drive data transmission and wireless communication of sensing nodes. The current mainstream low-power IoT communication chips (such as BLE, LoRa, NB-IoT) have a transmit and receive power consumption of tens or even hundreds of milliwatts, while the energy obtained by environmental energy harvesting is only at the microwatt level, which is unable to drive these types of nodes to work. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens of microwatts or even less than ten microwatts. The current mainstream method uses backscatter communication technology. Backscatter Communications is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve "Intelligent Connection of Everything". The methods that can be used include backscatter transmission (Backscatter Communications) technology.

[0182] The first device 101 shown in FIG1A may be any device that performs wireless communication using a backscatter transmission mechanism.

[0183] As shown in Figure 1B, the backscatter transmission mechanism is a wireless communication mechanism that utilizes the principle of radio frequency signal backscattering with extremely low-power modulation and transmission technology. A reader sends a physical layer signal to an ambient IoT device. This physical layer signal can be a pulse signal or other AC signal. In some embodiments, this physical layer signal is used to provide energy for the ambient IoT device to transmit the signal. Therefore, this physical layer signal can be referred to as an excitation signal or trigger signal. For example, since a portion of the excitation signal is reflected when it reaches the ambient IoT device, the ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the intended information to enhance the reflection of the incident excitation signal and modulate the acquired sensor data onto the reflected signal to complete the data transmission. This process is similar to a reflector. Compared to other communication technologies, backscatter transmission does not require complex radio frequency structures, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing. Therefore, it can simplify the design of ambient IoT devices and significantly reduce the cost of ambient IoT device nodes. Ambient IoT devices are IoT devices that use environmental energy to operate. This environmental energy can include the aforementioned wireless signal energy, as well as other environmental capabilities such as geothermal energy and / or light energy.

[0184] Backscatter communication has been widely used in radio frequency identification (RFID) systems, with numerous large-scale commercial applications. Its operating principle is that a receiver (typically an RFID reader) transmits a radio frequency excitation signal, activating a passive node (typically an RFID tag). The tag then uses backscatter communication to modulate its information onto the radio frequency signal. The reader then receives the reflected signal from the passive tag and demodulates it, achieving information transmission.

[0185] At present, RFID technology also has many disadvantages, such as short coverage distance (the wireless signal will experience double path fading during the communication process, so the path loss is large and the effective communication distance is short), single channel transmission, the need for strict tag alignment, no power control, etc. There is a lot of room for improvement in RFID technology in terms of communication. It needs to be integrated with the Third Generation Partnership Project (3GPP) rd The 3GPP (3rd Generation Partnership Project) communication technology improves the wireless communication performance of RFID technology in the passive Internet of Things.

[0186] The new type of IoT devices we are targeting have the characteristics of low memory, low processing power, low battery, small data transmission, and massive deployment. Environmental IoT devices can be maintenance-free and have a long service life (for example, more than 10 years).

[0187] These new IoT devices require energy from radio waves transmitted by network nodes to power themselves. Therefore, until they receive energy, they are typically powered off, meaning they are disconnected from the network. To address this, the communication system must support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to expedite data communication.

[0188] Backscatter transmission network topologies can include one of the following:

[0189] Topology 1: As shown in Figure 1C, uplink (UL) and downlink (DL) data transmission is carried out directly between ambient IoT devices and access network devices.

[0190] Topology 2: As shown in Figure 1D, DL and UL data transmission occurs indirectly between ambient IoT devices and access network equipment. Intermediate nodes (also called auxiliary nodes) provide forwarding services. These intermediate nodes can include relays, integrated access backhaul (IAB), user equipment (UE), and repeaters (RP).

[0191] Topology 3: As shown in Figure 1E, ambient IoT devices and access network devices directly transmit or receive data in the DL or UL. Auxiliary nodes are located on the UL or DL, responsible for receiving or sending UL or DL ​​data. Examples of auxiliary nodes include relays, integrated access backhaul (IAB) nodes, terminals, and network controlled repeaters (NCRs).

[0192] Topology 4: As shown in Figure 1F, the ambient IoT device and the UE directly receive and transmit data on the downlink and uplink. The UE is responsible for collecting data and forwarding it to the network.

[0193] Ambient IoT communications (i.e., communications between ambient IoT devices and base stations (topology 1, as shown in Figure 1C) and UEs (topology 2, as shown in Figure 1D)) can use spectrum resources in three forms: in-band, guard-band, or stand-alone.

[0194] Among them, in-band refers to the uplink and / or downlink spectrum resources used for normal New Radio (NR) communications.

[0195] Guard-band is a spectrum resource that uses the guard band of the normal NR communication DL and / or UL spectrum.

[0196] Standalone networking uses spectrum resources unrelated to normal NR communications.

[0197] As shown in Figure 1G, devices that use the backscatter transmission mechanism for wireless communication can be divided into three types:

[0198] Device A: has no energy storage, cannot independently generate and / or amplify signals, and can only perform backscatter transmission.

[0199] Device B: Has energy storage, cannot generate signals independently, and can only perform backscatter transmission. The use of stored energy can include amplification of the backscattered signal.

[0200] Device C: has energy storage and can independently generate signals, that is, it has active radio frequency (RF) components for transmission.

[0201] It should be noted that each device in Figure 1G has two grids: the first grid indicates whether the device has the ability to independently generate signals; the second grid indicates whether the device has the ability to store energy. When a device's grid is unfilled, it indicates that the device does not have the corresponding capability; when a device's grid is filled, it indicates that the device has the corresponding capability.

[0202] In some embodiments, the following constraints are imposed on ambient IoT devices:

[0203] Category 1 devices have a peak power consumption of approximately 1μW, energy storage, and an initial sampling frequency offset (SFO) of up to 10X ppm. They have neither downlink nor uplink amplification. Their uplink transmission is backscattered on an externally provided carrier.

[0204] Category 2 devices have peak power consumption less than or equal to a few hundred μW, have energy storage, and have an initial SFO of up to 10X ppm. They also have downlink amplification and / or uplink amplification. Uplink transmissions can be generated internally or backscattered on an externally provided carrier. X is determined by the working group.

[0205] To support data transmission between ambient IoT devices, the network needs to support the following functions. A device in the network can support one or more functions.

[0206] The Energy Source (ES) function is only used by Device B and Device C.

[0207] The downlink transmission (DT) function sends instruction information to the environmental IoT device, thereby triggering the uplink transmission of the environmental IoT device.

[0208] This continuous wave (CW) function is used only by devices A and B. Ambient IoT devices use backscatter CW for uplink transmission. CW is actually a type of ES, and Ambient IoT devices can receive CW and store energy.

[0209] The uplink receiver (UR) function receives uplink information backscattered by environmental IoT devices, or receives uplink information actively transmitted by environmental IoT devices.

[0210] The device that performs the above-mentioned ES, DT, CW or UR functions may be a UE, a repeater or a base station, etc. A device may support only one of the above-mentioned functions. Alternatively, a device may also support multiple of the above-mentioned functions at the same time. Alternatively, a device may also support all of the above-mentioned functions at the same time.

[0211] FIG2A is an interactive diagram illustrating an information processing method according to an exemplary embodiment. As shown in FIG2A , the embodiment of the present disclosure relates to an information processing method for a communication system 100, the method comprising:

[0212] Step S2101: The second device sends a first instruction to the first device.

[0213] In some embodiments, the first device receives a first instruction sent by the second device.

[0214] In some embodiments, the first device may be a wireless device that does not have a power supply module, a wireless device whose power supply capability of its power supply module is extremely weak, a wireless device that has a power supply module but the power supply module has lost its power supply capability, or any wireless device that supports backscatter communication.

[0215] In some embodiments, the first device may be any passive device, an ambient energy device, or an ambient IoT device.

[0216] Exemplarily, the first device may be device A, device B and / or device C shown in FIG. 1G .

[0217] The second device can be any communication device that includes a power supply module. For example, the second device can be any type of communication device that includes a battery. For example, the communication device can include, but is not limited to, a mobile phone, a tablet computer, an in-vehicle device, a wearable device, a smart home device, and / or a smart office device.

[0218] The second device may include but is not limited to a server or an application function (AF).

[0219] Exemplarily, the first device is an IoT device, and the second device may be an IoT server.

[0220] In some embodiments, the second device may be any network device located within the trust domain of the mobile communication network.

[0221] In some embodiments, the second device may be any network device located in the trust domain of the mobile communication network. Such a second device may be connected to the mobile communication network through a network open function or the like.

[0222] In some embodiments, the second device sends a first signal to the first device, where the first signal carries a first instruction.

[0223] In some embodiments, the first signal may include, but is not limited to, a radio frequency signal.

[0224] In some embodiments, the first signal may be a signal carrying information content. After receiving the first signal, the first device may decode the first signal to extract the information carried in the first signal.

[0225] In some embodiments, the first instruction is used by the first device to generate a random number; the random number is used to determine the timing for the first device to send information to the second device. Exemplarily, the first instruction may be a Query instruction.

[0226] It can be understood that the second device sends the first instruction to the first device, so that the first device can generate a random number according to the first instruction; and determine whether to send information to the second device according to the random number.

[0227] In some embodiments, the first instruction carries a first parameter; the first parameter is used by the first device to generate a random number.

[0228] In some embodiments, the first parameter is used by the first device to determine a numerical range of the random number.

[0229] In some embodiments, the first instruction includes: first information; the first information is used by the first device to determine a reference threshold.

[0230] It should be noted that the second device may send the first information to the first device so that the first device determines the reference threshold configured by the second device for the first device according to the first information.

[0231] In some embodiments, the first information includes at least one of the following:

[0232] The first information field indicates a reference threshold;

[0233] The second information field carries index information; the index information is used to determine the reference threshold.

[0234] In some embodiments, the second information field may include one or more bits; different bit values ​​of the one or more bits are used to carry index information of different contents.

[0235] It should be noted that the first information may include only the first information field, which carries the reference threshold. Alternatively, the first information may include only the second information field, which carries index information; this index information can be used to determine the reference threshold. Alternatively, the first information may include both the first information field and the second information field, thereby carrying the reference threshold and the index information corresponding to the reference threshold.

[0236] It is worth noting that the mapping relationship between the index information and the reference threshold may be agreed upon by a protocol or pre-configured by the second device.

[0237] In some embodiments, the second device sends third information to the first device; the third information is used to indicate a mapping relationship between the index information and the reference threshold.

[0238] It can be understood that the second device can send third information to the first device in order to inform the first device of the mapping relationship between the index information configured by the second device and the reference threshold, so that the first device can determine the reference threshold based on the mapping relationship between the index information and the reference threshold, thereby reducing the amount of information carried by the first information.

[0239] Step S2102: The first device generates a random number according to the first instruction.

[0240] In some embodiments, the first device may generate a random number according to a first parameter carried in the first instruction.

[0241] Here, the random number may be an integer.

[0242] It should be noted that the first parameter can be used to determine the numerical range of the random number; the first device can determine the numerical range according to the first parameter, and generate the random number based on the numerical range.

[0243] In some embodiments, the first device determines a timing to send information to the second device based on a random number.

[0244] In some embodiments, the first device determines, based on the random number, a timing for sending information to the second device, including at least one of the following:

[0245] The random number is equal to the first value, and the first device sends information to the second device;

[0246] If the random number is not equal to the first value, the first device does not send information to the second device.

[0247] It should be noted that the first value may be a fixed value agreed upon in the protocol, for example, the first value is zero. Alternatively, the first value may be a value configured by the second device.

[0248] When the random number generated by the first device is equal to the first value, the first device may send information to the second device based on the signal energy of the first signal. It is understandable that when the random number is equal to the first value, the first device sends information to the second device via backscattering.

[0249] When the random number generated by the first device is not equal to the first value, the first device may start monitoring the instructions sent by the second device.

[0250] In some embodiments, the first device may receive a fourth instruction sent by the second device, and re-determine the timing for the first device to send information to the second device according to the fourth instruction.

[0251] In some embodiments, the fourth instruction may carry the first value.

[0252] In this way, the second device can dynamically adjust the timing at which the first device sends information to the second device through the fourth instruction.

[0253] Step S2103: The first device determines a reference threshold.

[0254] In some embodiments, the first device may determine a reference threshold based on the first information.

[0255] It should be noted that since the first information may carry a reference threshold and / or index information, if the first information carries a reference threshold, the first device may directly determine the reference threshold based on the first information. If the first information carries only index information, the first device may determine the reference threshold corresponding to the index information based on a mapping relationship between the index information and the reference threshold.

[0256] It is worth noting that the mapping relationship between the index information and the reference threshold may be agreed upon by a protocol or pre-configured by the second device.

[0257] Based on the first information, the first device learns the reference threshold configured for the first device by the second device, and then determines whether to ignore the second instruction sent by the second device based on the comparison result between the random number and the reference threshold. In this way, the second device can configure different reference thresholds for different first devices by sending the first information to different first devices, so that some of the multiple first devices can continue to participate in subsequent communications, while other first devices can ignore the subsequently received second instruction and not participate in subsequent communications.

[0258] In some embodiments, the first device may determine a first threshold corresponding to the random number from a plurality of reference thresholds based on the random number.

[0259] It should be noted that the multiple reference thresholds may be agreed upon in the protocol or pre-configured by the second device. After the first device generates a random number according to the first instruction, it may select a first threshold corresponding to the random number from the multiple reference thresholds based on the random number. In subsequent processing, the first device may determine whether to ignore the second instruction sent by the second device based on the comparison result between the random number and the first threshold.

[0260] In some embodiments, the difference between the first threshold and the random number among the multiple reference thresholds is the smallest.

[0261] For example, the multiple reference thresholds may be 20000, 15000, and 10000. When the random number generated by the first device is 28000, the first device may determine the first threshold to be 20000. When the random number generated by the first device is 16000, the first device may determine the first threshold to be 15000.

[0262] In some embodiments, the first threshold may be a threshold with the smallest value among a plurality of reference thresholds whose threshold values ​​are less than or equal to the random number.

[0263] For example, the multiple reference thresholds may be 20000, 15000, and 10000. When the random number generated by the first device is 28000, the first device may determine the first threshold to be 20000. When the random number generated by the first device is 18000, the first device may determine the first threshold to be 15000.

[0264] Step S2104: If the random number is greater than or equal to the reference threshold, the first device ignores the second instruction sent by the second device.

[0265] It should be noted that the first device can compare the generated random number with the reference threshold. If the random number is greater than or equal to the reference threshold, it means that the random number generated by the first device is larger. In order to achieve energy saving for the first and second devices, the first device can ignore the second instruction sent by the second device.

[0266] In some embodiments, the random number is smaller than a reference threshold, and the first device starts monitoring the second instruction.

[0267] It should be noted that, if the random number is smaller than the reference threshold, it means that the random number generated by the first device is small, and the first device starts monitoring the second instruction.

[0268] In some embodiments, the method further comprises:

[0269] When the random number is smaller than the reference threshold, the first device receives a third instruction, and the random number is reduced by 1.

[0270] In some embodiments, the third instruction is used to subtract 1 from the random number.

[0271] If the random number is less than the reference threshold and not equal to the first value, the first device may receive a third instruction sent by the second device. Each time the first device receives a third instruction, the random number is decremented by 1. For example, the third instruction may be a QueryAdjust instruction.

[0272] In some embodiments, the method further comprises one of the following:

[0273] The random number minus 1 is equal to the first value, and the first device sends information to the second device;

[0274] The random number after subtracting 1 is not equal to the first value, and the first device continues to monitor the instruction sent by the second device.

[0275] In some embodiments, the method further comprises:

[0276] When the random number is less than the reference threshold, the first device receives a fourth instruction;

[0277] According to the fourth instruction, the timing for the first device to send information to the second device is re-determined.

[0278] In some embodiments, the fourth instruction is used to determine a new timing for sending information.

[0279] In some embodiments, the fourth instruction is used by the first device to redetermine the first value.

[0280] When the random number is smaller than the reference threshold and is not equal to the first value, the first device may receive a fourth instruction sent by the second device; and re-determine the first value according to the fourth instruction.

[0281] In some embodiments, the method further comprises one of the following:

[0282] The random number is equal to the re-determined first value, and the first device sends information to the second device;

[0283] The random number is not equal to the re-determined first value, and the first device continues to monitor the instruction sent by the second device.

[0284] In some embodiments, the method further comprises:

[0285] When the random number is less than the reference threshold, the first device receives a sixth instruction sent by the second device;

[0286] According to the sixth instruction, the first device regenerates the random number.

[0287] In some embodiments, the sixth instruction is used to regenerate a random number.

[0288] If the random number is less than the reference threshold and not equal to the first value, the first device may receive a sixth instruction sent by the second device to regenerate a random number according to the sixth instruction, and determine whether to send information to the second device based on the regenerated random number.

[0289] In some embodiments, the sixth instruction carries a first parameter for reconfiguration of the second device.

[0290] In some embodiments, the method further comprises at least one of the following:

[0291] The regenerated random number is greater than the first value, and the first device continues to monitor the second instruction;

[0292] The regenerated random number is equal to the first value, and the first device sends information to the second device.

[0293] In the case where the random number is greater than or equal to the reference threshold and the first device ignores the second instruction sent by the second device, the present disclosure provides the following two optional implementations.

[0294] Optional implementation method 1:

[0295] In some embodiments, the second instruction includes: all instructions sent by the second device when the random number of the first device is greater than or equal to a reference threshold.

[0296] In some embodiments, the second instruction may be any one of the third instruction, the fourth instruction, and the sixth instruction.

[0297] When the random number is greater than or equal to the reference threshold, the first device ignores all instructions sent by the second device.

[0298] It should be noted that after the first device generates a random number according to the first instruction, if the random number is greater than or equal to the reference threshold, the first device can directly ignore all subsequent instructions sent by the second device. In other words, the first device can directly switch to a sleep state and no longer receive instructions sent by the second device; thereby reducing the power consumption of the first device.

[0299] Optional implementation method 2:

[0300] In some embodiments, the second instruction includes: a portion of an instruction sent by the second device when the random number of the first device is greater than or equal to a reference threshold.

[0301] In some embodiments, the second instruction may be any one of the third instruction and the fourth instruction.

[0302] When the random number is greater than or equal to the reference threshold, the first device ignores the second instruction sent by the second device and starts monitoring the sixth instruction.

[0303] It should be noted that if the random number is greater than or equal to the reference threshold and the first device receives the second instruction, the first device may directly ignore the second instruction. If the random number is greater than or equal to the reference threshold and the first device receives the sixth instruction, the first device regenerates the random number according to the sixth instruction.

[0304] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0305] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0306] The information processing method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2104. For example, steps S2101 and S2102 may be implemented as independent embodiments, and step S2101 combined with steps S2102 and S2103 may be implemented as independent embodiments, but the present disclosure is not limited thereto.

[0307] In some embodiments, steps S2103 and S2104 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that when the random number generated by the first device is equal to the first value, the first device directly sends information to the second device without determining a reference threshold.

[0308] In some embodiments, step S2104 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that if the random number generated by the first device is less than the reference threshold, the first device does not need to ignore the second instruction sent by the second device, but instead will initiate monitoring of the second instruction.

[0309] FIG2B is an interactive diagram illustrating an information processing method according to an exemplary embodiment. As shown in FIG2B , the embodiment of the present disclosure relates to an information processing method for use in a communication system 100, the method comprising:

[0310] Step S2201: The second device sends a first instruction to the first device.

[0311] In some embodiments, the first device receives a first instruction sent by the second device.

[0312] In some embodiments, the first device may be a wireless device that does not have a power supply module, a wireless device whose power supply capability of its power supply module is extremely weak, a wireless device that has a power supply module but the power supply module has lost its power supply capability, or any wireless device that supports backscatter communication.

[0313] In some embodiments, the first device may be any passive device, an ambient energy device, or an ambient IoT device.

[0314] Exemplarily, the first device may be device A, device B and / or device C shown in FIG. 1G .

[0315] The second device can be any communication device that includes a power supply module. For example, the second device can be any type of communication device that includes a battery. For example, the communication device can include, but is not limited to, a mobile phone, a tablet computer, an in-vehicle device, a wearable device, a smart home device, and / or a smart office device.

[0316] The second device may include but is not limited to a server or an application function (AF).

[0317] Exemplarily, the first device is an IoT device, and the second device may be an IoT server.

[0318] In some embodiments, the second device may be any network device located within the trust domain of the mobile communication network.

[0319] In some embodiments, the second device may be any network device located in the trust domain of the mobile communication network. Such a second device may be connected to the mobile communication network through a network open function or the like.

[0320] In some embodiments, the second device sends a first signal to the first device, where the first signal carries a first instruction.

[0321] In some embodiments, the first signal may include, but is not limited to, a radio frequency signal.

[0322] In some embodiments, the first signal may be a signal carrying information content. After receiving the first signal, the first device may decode the first signal to extract the information carried in the first signal.

[0323] In some embodiments, the first instruction is used by the first device to generate a random number; the random number is used to determine the timing for the first device to send information to the second device. Exemplarily, the first instruction may be a Query instruction.

[0324] It can be understood that the second device sends the first instruction to the first device, so that the first device can generate a random number according to the first instruction; and determine whether to send information to the second device according to the random number.

[0325] In some embodiments, the first instruction carries a first parameter; the first parameter is used by the first device to generate a random number.

[0326] In some embodiments, the first parameter is used by the first device to determine a numerical range of the random number.

[0327] In some embodiments, the first instruction includes: first information; the first information is used by the first device to determine a reference threshold.

[0328] It should be noted that the second device may send the first information to the first device so that the first device determines the reference threshold configured by the second device for the first device according to the first information.

[0329] In some embodiments, the first information includes at least one of the following:

[0330] The first information field indicates a reference threshold;

[0331] The second information field carries index information; the index information is used to determine the reference threshold.

[0332] It should be noted that the first information may include only the first information field, which carries the reference threshold. Alternatively, the first information may include only the second information field, which carries index information; this index information can be used to determine the reference threshold. Alternatively, the first information may include both the first information field and the second information field, thereby carrying the reference threshold and the index information corresponding to the reference threshold.

[0333] It is worth noting that the mapping relationship between the index information and the reference threshold may be agreed upon by a protocol or pre-configured by the second device.

[0334] In some embodiments, the second device sends third information to the first device; the third information is used to indicate a mapping relationship between the index information and the reference threshold.

[0335] It can be understood that the second device can send third information to the first device in order to inform the first device of the mapping relationship between the index information configured by the second device and the reference threshold, so that the first device can determine the reference threshold based on the mapping relationship between the index information and the reference threshold, thereby reducing the amount of information carried by the first information.

[0336] In some embodiments, the first instruction further includes: timer information.

[0337] It should be noted that the timer information is used to indicate the configuration parameters of the timer, such as the timing duration of the timer, the triggering condition of the timer, etc.

[0338] In some embodiments, the triggering condition of the timer may be that the random number of the first device is greater than or equal to a reference threshold.

[0339] It can be understood that, when the first instruction carries timer information and the random number of the first device is greater than or equal to the reference threshold, the first device may start the timer.

[0340] In some embodiments, the timer information is used to indicate a time length for which the first device ignores the second instruction when the random number is greater than or equal to a reference threshold.

[0341] Step S2202: The first device generates a random number according to the first instruction.

[0342] In some embodiments, the optional implementation of step S2202 can refer to the optional implementation of step S2102 in Figure 2A and other related parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0343] Step S2203: The first device determines a reference threshold.

[0344] In some embodiments, the optional implementation of step S2203 can refer to the optional implementation of step S2103 in Figure 2A and other related parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0345] Step S2204: If the random number is greater than or equal to the reference threshold, the first device ignores the second instruction sent by the second device during the timer operation.

[0346] It should be noted that, when the first device receives the timer information, the first device may compare the generated random number with the reference threshold to determine whether to ignore the second instruction sent by the second device based on the comparison result of the random number and the reference threshold.

[0347] In some embodiments, the random number is greater than or equal to a reference threshold, and the first device ignores the second instruction sent by the second device during the timer running, including:

[0348] If the random number is greater than or equal to a reference threshold, the first device starts a timer;

[0349] During the running of the timer, the first device ignores the second instruction sent by the second device.

[0350] It should be noted that when the first device receives timer information and the random number is greater than or equal to the reference threshold, the first device may start the timer and ignore the second instruction sent by the second device during the timer's operation. In this way, if the random number is greater than or equal to the reference threshold, the first device may ignore or not receive the second instruction sent by the second device for a certain period of time (i.e., during the timer's operation); alternatively, if the random number is greater than or equal to the reference threshold, the second device may stop sending the second instruction to the first device during the timer's operation, thereby achieving energy saving for the first and second devices.

[0351] In some embodiments, the timing duration of the timer may be determined according to the timer information. It should be noted that the timer information may indicate the timing duration of the timer.

[0352] In some embodiments, the timing duration of the timer may be determined according to a second parameter.

[0353] It should be noted that, when the timer information does not include the timing duration of the timer, the first device may determine the timing duration of the timer according to the second parameter.

[0354] In some embodiments, the random number is smaller than a reference threshold, and the first device starts monitoring the second instruction.

[0355] It should be noted that, if the random number is smaller than the reference threshold, it means that the random number generated by the first device is small, and the first device starts monitoring the second instruction.

[0356] In some embodiments, the method further comprises:

[0357] When the random number is smaller than the reference threshold, the first device receives a third instruction, and the random number is reduced by 1.

[0358] In some embodiments, the third instruction is used to subtract 1 from the random number.

[0359] If the random number is less than the reference threshold and not equal to the first value, the first device may receive a third instruction sent by the second device. Each time the first device receives a third instruction, the random number is decremented by 1. For example, the third instruction may be a QueryAdjust instruction.

[0360] In some embodiments, the method further comprises one of the following:

[0361] The random number minus 1 is equal to the first value, and the first device sends information to the second device;

[0362] The random number after subtracting 1 is not equal to the first value, and the first device continues to monitor the instruction sent by the second device.

[0363] In some embodiments, the method further comprises:

[0364] When the random number is less than the reference threshold, the first device receives a fourth instruction;

[0365] According to the fourth instruction, the timing for the first device to send information to the second device is re-determined.

[0366] In some embodiments, the fourth instruction is used to determine a new timing for sending information.

[0367] In some embodiments, the fourth instruction is used by the first device to redetermine the first value.

[0368] When the random number is smaller than the reference threshold and is not equal to the first value, the first device may receive a fourth instruction sent by the second device; and re-determine the first value according to the fourth instruction.

[0369] In some embodiments, the method further comprises one of the following:

[0370] The random number is equal to the re-determined first value, and the first device sends information to the second device;

[0371] The random number is not equal to the re-determined first value, and the first device continues to monitor the instruction sent by the second device.

[0372] In some embodiments, the method further comprises:

[0373] When the random number is less than the reference threshold, the first device receives a sixth instruction sent by the second device;

[0374] According to the sixth instruction, the first device regenerates the random number.

[0375] In some embodiments, the sixth instruction is used to regenerate a random number.

[0376] If the random number is less than the reference threshold and not equal to the first value, the first device may receive a sixth instruction sent by the second device to regenerate a random number according to the sixth instruction, and determine whether to send information to the second device based on the regenerated random number.

[0377] In some embodiments, the sixth instruction carries a first parameter for reconfiguration of the second device.

[0378] In some embodiments, the method further comprises at least one of the following:

[0379] The regenerated random number is greater than the first value, and the first device continues to monitor the second instruction;

[0380] The regenerated random number is equal to the first value, and the first device sends information to the second device.

[0381] In some embodiments, the method further comprises:

[0382] A fifth instruction sent by the second device is received, wherein the fifth instruction carries the second parameter or the third parameter.

[0383] In some embodiments, the fifth instruction carrying the second parameter is used to restart the timer of the first device when the random number is greater than or equal to the reference threshold.

[0384] In some embodiments, the fifth instruction carrying the third parameter is used for the first device, when the random number is greater than or equal to the reference threshold, to adjust the value of the random number according to the third parameter.

[0385] It should be noted that the control object of the fifth instruction is the first device whose random number is greater than or equal to the reference threshold; therefore, when the random number is less than the reference threshold and the fifth instruction is received, the first device may ignore the fifth instruction.

[0386] In the case where the random number is greater than or equal to the reference threshold and the first device ignores the second instruction sent by the second device during the operation of the timer, the present disclosure provides the following two optional implementations.

[0387] Optional implementation mode 1: The second instruction includes: all instructions sent by the second device during the operation of the timer.

[0388] In some embodiments, the second instruction may be any one of the third instruction, the fourth instruction, the fifth instruction, and the sixth instruction.

[0389] When the random number is greater than or equal to the reference threshold, the first device ignores all instructions sent by the second device during the running of the timer.

[0390] It should be noted that after the first device generates a random number according to the first instruction, if the random number is greater than or equal to the reference threshold, the first device starts the timer; during the operation of the timer, the first device can directly ignore all subsequent instructions sent by the second device. In other words, the first device can directly switch to a sleep state during the operation of the timer and does not receive instructions sent by the second device during the operation of the timer; thereby reducing the power consumption of the first device.

[0391] Optional implementation method 2:

[0392] In some embodiments, the second instruction includes: a portion of an instruction sent by the second device during the running of a timer.

[0393] In some embodiments, the second instruction may be any one of the third instruction and the fourth instruction.

[0394] In some embodiments, when the random number is greater than or equal to the reference threshold, the first device ignores the second instruction sent by the second device during the operation of the timer, and starts monitoring the fifth instruction or the sixth instruction sent by the second device during the operation of the timer.

[0395] It should be noted that, when the random number is greater than or equal to the reference threshold and the timer is running and the first device receives the second instruction, the first device may directly ignore the second instruction.

[0396] In a case where the random number is greater than or equal to the reference threshold and the timer is running and the first device receives the fifth instruction, the first device executes the fifth instruction.

[0397] When the random number is greater than or equal to the reference threshold and the timer is running and the first device receives the sixth instruction, the first device regenerates the random number according to the sixth instruction.

[0398] In some embodiments, when the random number is greater than or equal to the reference threshold and the timer is running and the first device receives a fifth instruction carrying the second parameter, the first device restarts the timer.

[0399] It should be noted that, during the operation of the timer, if the first device receives a fifth instruction carrying the second parameter, the first device may restart the timer.

[0400] In some embodiments, the timing duration of the restarted timer may be determined by a second parameter.

[0401] It is worth noting that during the operation of the timer, the second device can send a fifth instruction carrying a second parameter to the first device so that the first device can restart the timer according to the second parameter, thereby adjusting the length of time that the first device ignores the second instruction sent by the second device.

[0402] In some embodiments, when the random number is greater than or equal to the reference threshold and the timer is running and the first device receives a fifth instruction carrying the third parameter, the third parameter is subtracted from the random number.

[0403] It is worth noting that, during the operation of the timer, the second device may send a fifth instruction carrying a third parameter to the first device, so that the first device may adjust the value of the random number according to the third parameter.

[0404] In some embodiments, the method further comprises at least one of the following:

[0405] The random number after subtracting the third parameter is greater than the first value and during the running of the timer, the first device ignores the second instruction sent by the second device during the running of the timer;

[0406] The random number after subtracting the third parameter is less than or equal to the first value and during the running of the timer, the first device sends information to the second device.

[0407] Step S2205: When the timer times out, the second device sends a fifth instruction to the first device.

[0408] In some embodiments, the timer times out and the first device receives a fifth instruction sent by the second device.

[0409] In some embodiments, when the timer times out, the first device starts listening for the fifth instruction.

[0410] In some embodiments, when the timer times out, the first device also starts listening for the second instruction.

[0411] It should be noted that after the timer times out, the first device may start to monitor all instructions sent by the second device.

[0412] In some embodiments, the first device determines second information; the second information includes at least one of the following:

[0413] The second parameter is used to determine the timing duration of the timer;

[0414] The third parameter is used by the first device to adjust the value of the random number.

[0415] In some embodiments, the fifth instruction sent by the second device carries the second parameter or the third parameter.

[0416] It is understandable that the first device can determine the second information according to the information content carried by the fifth instruction.

[0417] In some embodiments, the first device determines the second information based on the first information.

[0418] It should be noted that, when the fifth instruction sent by the second device does not carry the second parameter or the third parameter, the first device can determine the second information according to the first information.

[0419] In some embodiments, the first device determines the second information based on the first information, including:

[0420] The second information is determined from the mapping information according to the index information and / or the reference threshold.

[0421] It should be noted that the first information may carry index information and / or a reference threshold, and the first device may determine the second information from the mapping information according to the index information and / or the reference threshold.

[0422] The mapping information may be agreed upon by a protocol, or may be pre-configured by the second device. The mapping information is used to indicate a mapping relationship between the second information and the index information and / or the reference threshold.

[0423] In some embodiments, the mapping information includes one of the following:

[0424] first mapping information, indicating a mapping relationship between the index information and the second parameter and / or the third parameter;

[0425] second mapping information, indicating a mapping relationship between the reference threshold and the second parameter and / or the third parameter;

[0426] The third mapping information indicates a mapping relationship between the index information, the reference threshold, and the second parameter and / or the third parameter.

[0427] In some embodiments, the first device determines, based on the random number, second information corresponding to the random number from the mapping information.

[0428] It should be noted that, when the fifth instruction sent by the second device does not carry the second parameter or the third parameter, the first device can determine the second information according to the value of the generated random number.

[0429] In some embodiments, the first device may determine, based on the random number, a first threshold corresponding to the random number and second information corresponding to the first threshold from the mapping information.

[0430] After the first device generates a random number according to the first instruction, it can select the first threshold corresponding to the random number from the mapping information based on the random number, and determine the second parameter and / or third parameter associated with the first threshold in the mapping information as the second parameter and third parameter corresponding to the random number.

[0431] In some embodiments, the first threshold may be a reference threshold having the smallest difference between the threshold value and the random number among multiple reference thresholds of the mapping information.

[0432] In some embodiments, the first threshold may be a threshold with the smallest value among a plurality of reference thresholds whose threshold values ​​are less than or equal to the random number.

[0433] In some embodiments, the method further comprises:

[0434] When the timer times out and the first device receives the second parameter, the first device restarts the timer;

[0435] During the running of the restarted timer, the first device continues to ignore the second instruction sent by the second device.

[0436] It should be noted that when the timer times out and the first device receives the second parameter, the first device can restart the timer; and during the operation of the restarted timer, the first device continues to ignore the second instruction sent by the second device; thereby extending the time length that the first device ignores the second instruction.

[0437] It is worth noting that the second parameter received by the first device here may be the second parameter carried in the fifth instruction; or, it may be the second parameter determined based on the first information carried in the first instruction; or, it may be the second parameter determined based on a random number generated based on the received first instruction.

[0438] In some embodiments, the method further comprises:

[0439] When the timer times out and the first device receives the third parameter, the third parameter is subtracted from the random number;

[0440] If the random number after subtracting the third parameter is greater than the first value, the first device starts monitoring the second instruction;

[0441] If the random number after subtracting the third parameter is less than or equal to the first value, the first device sends information to the second device.

[0442] It should be noted that when the timer times out and the first device receives the third parameter, the third parameter can be subtracted from the random number; thereby determining the timing for the first device to send information to the second device based on the random number after subtracting the third parameter.

[0443] It is worth noting that the third parameter received by the first device here may be the third parameter carried in the fifth instruction; or, it may be the third parameter determined based on the first information carried in the first instruction; or, it may be the third parameter determined based on a random number generated based on the received first instruction.

For example, steps S2201 and S2202 may be implemented as independent embodiments, step S2201 combined with steps S2202 and S2203 may be implemented as an independent embodiment, and step S2201 combined with steps S2202, S2203, and S2204 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0445] In some embodiments, steps S2203, S2204, and S2205 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that when the random number generated by the first device is equal to the first value, the first device directly sends information to the second device without determining a reference threshold.

[0446] In some embodiments, steps S2204 and S2205 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that if the random number generated by the first device is less than the reference threshold, the first device does not need to ignore the second instruction sent by the second device, but instead will initiate monitoring of the second instruction.

[0447] In some embodiments, step S2205 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that if the first information carried by the first instruction does not include timer information, the first device whose random number is greater than or equal to the reference threshold will not start the timer, so the first device does not need to ignore or monitor the instruction sent by the second device based on whether the timer has timed out.

[0549] FIG5 is an interactive diagram illustrating an information processing method according to an exemplary embodiment. As shown in FIG5 , the embodiment of the present disclosure relates to an information processing method for a communication system 100, and the method includes one of the following steps:

[0550] Step S5101: The second device sends a first instruction to the first device;

[0551] Step S5102: The first device generates a random number according to the first instruction; the random number is used to determine the timing for the first device to send information to the second device;

[0552] Step S5103: If the random number is greater than or equal to the reference threshold, the first device ignores the second instruction sent by the second device.

[0553] In some embodiments, the above method may include the methods of the above embodiments on the communication system side, the first device side, the second device side, etc., which will not be repeated here.

[0554] In some embodiments, in an RFID communication system, based on usage functions, commands are divided into three categories: tag selection (Select), inventory (Inventory) and access (Access).

[0555] There are five inventory commands: Query, QueryAdjust, QueryRep, ACK, and NAK. As shown in FIG6 , FIG6 is a schematic diagram showing a tag identification and response according to an exemplary embodiment.

[0556] After receiving a valid Query command, each tag selected by the set criteria generates a random number (similar to rolling a dice), and each tag with a random number of zero will generate a response (send back a temporary password RN16, a 16-bit random number) and move to the Reply state; tags that meet other conditions will change certain attributes and flags, thereby exiting the above tag group, which helps to reduce duplicate identification.

[0557] After receiving a valid QueryAdjust command, each tag generates a new random number (similar to re-rolling a dice). The rest of the process is the same as receiving a Query command.

[0558] After receiving a valid QueryRep command, the tag only decrements the original random number of each tag in the tag group by one. The other processes are the same as receiving a Query command.

[0559] Only the single tag can receive a valid ACK command (using the temporary password RN16 or handle); after receiving the ACK command, the tag replies with the content of the Electronic Product Code (EPC) area.

[0560] After receiving a valid NAK command, all tags in the ready and killed states switch to the arbitrate state, except for those in the ready and killed states which remain in their original states.

[0561] In some embodiments, after the tag receives the Query command sent by the interrogator, the Query command carries a parameter Q; the value of the parameter Q is 0 to 15, and the tag generates a random number using a random number generator based on the parameter Q (wherein the value range of the random number is 0 to 2 Q -1).

[0562] Every time the tag receives a QueryRep command, the random number is reduced by 1 until it reaches 0; at this point the tag can perform backscattering to send information to the interrogator.

[0563] If the random number generated by the tag is very large, the tag may receive countless QueryRep commands before the random number is reduced to 0 and the information is sent to the interrogator. Such excessive reception of QueryRep commands will cause the tag to consume power.

[0564] In some embodiments, the network controls tags that generate large random numbers and temporarily excludes them from participating in the inventory. The network then adjusts parameter Q to allow these tags to participate again. This allows tags to ignore decoding QueryRep commands, saving power.

[0565] Option 1:

[0566] The network side (i.e., the interrogator) sends a command to the tag (e.g., a Query command, where the Query command includes a parameter Q, and the parameter Q is used by the tag (i.e., the environmental IoT device) to generate a random number RN16). At the same time, the network side also configures a threshold Th-RN16.

[0567] If the random number RN16 generated by the tag is greater than or equal to Th-RN16, the tag ignores the subsequently received command for determining a new slot, or the command for subtracting RN16 by 1 (eg, QueryRep command).

[0568] If the tag can identify the received command, for example, it recognizes that the command is for RN16 minus 1, it will not decode the specific command content. In other words, the tag will not participate in the inventory task temporarily.

[0569] The tag waits for a command (such as a QueryAdjust command) sent by the network device that carries the newly configured parameter Q, generates a new random number, and determines whether to re-participate in the inventory task based on the newly generated random number.

[0570] Option 2:

[0571] The network side (i.e., the interrogator) sends a command to the tag (e.g., a Query command, where the Query command includes a parameter Q, which is used by the tag (i.e., the environmental IoT device) to generate a random number RN16). At the same time, the network side also configures a threshold Th-RN16 and a timer T1.

[0572] If the random number RN16 generated by the tag is greater than or equal to Th-RN16, the tag starts the timer T1. Before the timer T1 times out, the tag does not receive or ignores the next air interface command sent by the network side.

[0573] After timer T1 times out, the tag starts to monitor the air interface commands sent by the network side.

[0574] The air interface command sent by the network side after the timer expires may include:

[0575] Configure the timing and / or threshold Th-RN16 command of timer T1; after receiving the command, the tag whose random number RN16 is greater than or equal to Th-RN16 restarts timer T1.

[0576] Configure delta-RN16 and / or threshold Th-RN16 command; after receiving the command, the tag whose random number RN16 is greater than or equal to Th-RN16 will reduce RN-16 by delta-RN16 and start listening for commands from the network side again.

[0577] In some embodiments, the threshold Th-RN16, timer T1 and delta-RN16 may have multiple configurations, and the tag selects the appropriate timing time and delta-RN16 according to the generated random number RN16.

[0578] As shown in Table 1, Table 1 shows a configuration set for the threshold Th-RN16, timer T1, and delta-RN16. For a tag with RN16 = 28000, the timer and delta-RN16 corresponding to index 0 can be selected. For a tag with RN16 = 18000, the timer and delta-RN16 corresponding to index 1 can be selected.
