[0003] Passive Ambient Internet of Things (AIoT) terminal devices generally refer to those with no energy reserves or very low energy reserves. Passive IoT terminal devices generally cannot actively initiate services and require network signals as stimulation (energy supply). They then perform simple processing on downlink messages and send uplink messages, such as sending reflected signals. In some scenarios, after a network device sends a downlink message, it may receive reflected signals from a large number of IoT terminals. Due to the possibility of severe signal interference between reflected signals from different IoT terminal devices, the network device cannot correctly demodulate the reflected signals.

[0100] The following embodiments of the technical solution of the present disclosure are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present disclosure and are therefore only examples and are not intended to limit the scope of protection of the present disclosure.

[0101] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure; the terms "including" and "having" and any variations thereof in the specification and claims of the present disclosure and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0102] In related technologies, passive IoT terminal devices generally have no energy reserves, or only very low energy reserves. When operating, passive IoT terminal devices typically receive commands from the network to read and write data in terminal registers, set their status, and perform other operations. Typical operations include obtaining the terminal's device index and querying register data. After the network sends a downlink signal, any terminal receiving the downlink signal may reflect the signal. If a large number of IoT terminals are deployed on the network, the network will receive a large number of reflected signals, which may interfere with each other and prevent the network from demodulating the signal.

[0103] In some embodiments, a method for accessing a passive IoT device applied to a terminal device is provided, which can solve the technical defects existing in the related art. As shown in Figure 1, the above-mentioned access method may include the following steps:

[0104] Step S11, receiving an access control signal indicating resource allocation information, and determining group information corresponding to the terminal device based on the resource allocation information;

[0105] Step S12: executing a predefined operation corresponding to the group information according to the group information of the terminal device.

[0106] Exemplarily, the terminal device may be a passive IoT device that can receive access control signals broadcast by network devices. This access control signal can be used to indicate resource allocation information, which can be used to indicate grouping information for each terminal device. Furthermore, it can also be used to indicate the subgrouping information of terminal devices, or specific terminal devices, that currently need to execute network-side instructions. After receiving the resource allocation information broadcast by the network, the terminal device can parse it, extract parameters, and perform calculations to determine the grouping information of the terminal devices to which the terminal device belongs. Once the grouping information is determined, the terminal device corresponding to the selected group can execute the predefined operations corresponding to the grouping information, thereby responding to and providing feedback on network-side instructions, thereby implementing group processing for the passive IoT devices.

[0107] In some exemplary embodiments, the resource allocation information may include any one or a combination of any multiple of the following: number of groups, target group index, target terminal identification information, and target parameter threshold information.

[0108] In some exemplary embodiments, the resource allocation information includes: the number of packets.

[0109] In the above-mentioned step S11, the determining of the group information corresponding to the terminal device based on the resource allocation information includes: determining the group index of the terminal device based on the number of groups and the index parameter of the terminal device.

[0110] Specifically, the terminal device can calculate the group information of the terminal device to which the terminal device belongs by the number of groups. Specifically, the terminal device parses the resource allocation information currently received and extracts the number of groups carried therein. The terminal device performs calculations based on the index parameter of the terminal device and the number of groups, and uses the calculation result to determine the group index to which the terminal device belongs. For example, a modulo operation (mod) can be performed between the index parameter and the number of groups, and the remainder obtained is the group index of the terminal device. For example, the index parameter of the terminal device is 7, the number of groups is 3, and the result of 7mod3 is 1, that is, the group index of the terminal device is 1. Exemplarily, the index parameter of the terminal device can be configured according to the identity identification information of the terminal device; or, it can be configured according to a random number generated by the terminal device.

[0111] Of course, in some exemplary embodiments, the grouping result calculated by the terminal device based on the number of groups carried in the resource allocation information can be used as a temporary grouping result of the terminal device by the network side. Alternatively, in some application scenarios, it can also be used as a permanent grouping result of the terminal device by the network side.

[0112] Of course, in other exemplary embodiments of the present disclosure, other calculation methods may be used to calculate the group index. For example, other algorithms that can achieve terminal discretization can be used to distribute terminal devices to each group as evenly as possible according to the number of groups configured by the network.

[0113] In some exemplary embodiments, the resource allocation information includes: the number of packets and a target packet index.

[0114] Referring to FIG. 2 , in the above step S11, determining the grouping information corresponding to the terminal device based on the resource allocation information includes:

[0115] Step S21, determining a group index of the terminal device based on the number of groups and an index parameter of the terminal device;

[0116] Step S22: compare the group index of the terminal device with the target group index to obtain an index comparison result.

[0117] In some exemplary embodiments, in the above-mentioned step S12, executing the predefined operation corresponding to the grouping information includes: triggering execution of the predefined operation corresponding to the grouping index when the index comparison result is the same.

[0118] Exemplarily, the access control signal sent by the network device includes resource allocation information; wherein, the resource allocation information may include the number of groups, which is used by the terminal device to calculate the corresponding group index; in addition, it may also carry parameters of the target group index, which is used to indicate the terminal device group required for the current service of the network device, and the terminal devices in this group are required to respond to the network device.

[0119] Specifically, the terminal device may first parse the resource allocation information to obtain the parameter values ​​of the number of groups and the target group index contained therein. Then, the corresponding group index may be calculated based on the number of groups, for example, the group index of the terminal device calculated above is 1. Then, the current group index may be compared with the target group index to determine whether the parameters are consistent. If the parameters are judged to be consistent, it may be determined that the group to which the current terminal device belongs is the terminal device group required for the current service on the network side, and the predefined operation corresponding to the group needs to be executed. Alternatively, if the parameters are judged to be inconsistent, for example, the group index of the terminal device currently calculated is 1, and the target group index is 2, then the terminal device is not the group information of the terminal device selected by the network side for this service; at this time, the terminal device may not perform any operation, or may only feedback an uplink information to the network side to indicate the terminal device's response to the resource allocation information. The device identification and / or group index of the terminal device may be carried in the response information.

[0120] For example, 2 bits may be predefined to indicate the number of groups and the target group index, respectively. For example, if the value of the 2 bits is 01, it implicitly indicates that the terminal devices are grouped into 4 groups and the group index of the current device group is 1.

[0121] Of course, in some exemplary embodiments, the resource allocation information may carry one or more sub-target group indexes, thereby enabling the network side to select group information of one or more terminal devices.

[0122] In some exemplary embodiments, the resource allocation information includes: number of packets, target packet index, and target terminal identification information.

[0123] Referring to FIG3 , in the above step S11, determining the grouping information corresponding to the terminal device based on the resource allocation information includes:

[0124] Step S31, determining a group index of the terminal device based on the number of groups and an index parameter of the terminal device;

[0125] Step S32: compare the group index of the terminal device with the target group index. When the index comparison results are the same, compare the identification information of the terminal device with the target terminal identification information to obtain a terminal identification comparison result.

[0126] In some exemplary embodiments, in the above-mentioned step S12, executing the predefined operation corresponding to the grouping information includes: triggering execution of the predefined operation corresponding to the grouping index when the terminal identification comparison results are the same.

[0127] Specifically, the resource allocation information may also include target terminal identification information; and the target terminal device identification information may be one or more. The network side can use this target terminal identification information to select one or more specific terminal devices within a specified device group. For example, the resource allocation information may include one or more target terminal identification information, thereby enabling the network side to select one or more terminal devices.

[0128] Exemplarily, when the access control signal indicates multiple terminal devices, it can directly send multiple terminal device ID identification information, or it can send the range information of the terminal device ID or the terminal device ID feature identification, or a bit string data of several bits, and the bit string data is used to correspond to a part of the terminal device ID. For example: the several bits of bit string data correspond to the several bits of data on the leftmost (highest) side of the terminal device ID. If they match, it indicates the selected terminal device. Similarly, it can also correspond to the several bits of data on the rightmost (lowest) side of the terminal device ID, or the several bits of data in the middle of the terminal device ID.

[0129] Specifically, after receiving the broadcast resource allocation information, the terminal device can first parse it to extract the number of packets, target packet index, and target terminal identification information contained therein; wherein, the target packet index and target terminal identification information can be one or more respectively. After calculating the packet information corresponding to the terminal device based on the number of packets, it can be compared with the target packet index first. If the packet index comparison result is different, no operation can be performed. Alternatively, when the packet information corresponding to the terminal device is the same as the target packet index, the device index identifier of the terminal device is compared with the target terminal identification information; if they are the same, it indicates that the terminal device is the device currently required by the network side, and the terminal device can perform predefined operations. Alternatively, if the comparison is different, it indicates that the terminal device is not the terminal device required by the current service on the network side, and no operation can be performed; alternatively, only an uplink response information can be fed back.

[0130] In some exemplary embodiments, the resource allocation information includes target signal parameter threshold information.

[0131] In the above-mentioned step S11, the determining of the group information corresponding to the terminal device based on the resource allocation information includes: determining the parameter interval corresponding to each group according to the target signal parameter threshold information; determining the corresponding parameter interval based on the target signal parameter of the terminal device, and the group index corresponding to the parameter interval.

[0132] Specifically, the network side can send resource allocation information to the terminal device through the air interface, and carry the target signal parameter threshold information in the resource allocation information. The target signal parameter threshold information can be a signal-related threshold value. For example, the above-mentioned target signal parameter threshold can be a signal threshold such as RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Received Quality), SINR (Signal to Interference plus Noise Ratio), a receiving power threshold, etc.; or, it can also be a TA (Timing Advance) threshold, etc. Of course, the parameter thresholds of one or more target signals can be indicated in the resource allocation information.

[0133] For example, if the resource allocation information includes an RSRP signal threshold, the terminal devices will be divided into two groups: those with received signal strength below the configured threshold and those above the configured threshold. Alternatively, if the resource allocation information includes two RSRP signal thresholds, A and B, the terminal devices will be divided into three groups: those with received signal strength below A, above A and below B, and above B.

[0134] Exemplarily, the resource allocation information may also include the maximum and minimum values ​​of the signal threshold, as well as the step size, to implement grouping. For example, the grouping information may include: {minimum value, minimum value + step size}, {minimum value, minimum value + step size * 2}, ... {maximum value - step size, maximum value}. Alternatively, the resource allocation information may also include the maximum and minimum values ​​of the signal threshold, as well as the number of groups, to implement grouping. Correspondingly, the grouping step size is (maximum value - minimum value) / number of groups.

[0135] For the terminal device, after calculating the group information, the signal corresponding to the terminal device can be obtained, and the group index to which it belongs can be determined based on the parameter interval to which the target signal parameter of the terminal device belongs.

[0136] Exemplarily, resource allocation information may also include a combination of other contents, for example, it may include: number of groups, target terminal identification information; or it may include: target parameter threshold information, target group number index; or it may include: target parameter threshold information, target group number index, target terminal identification information; and so on.

[0137] In some exemplary embodiments, the predefined operation includes any one of: determining corresponding uplink resource data based on the grouping information, triggering the terminal device to perform an access operation, triggering the terminal device to feedback an uplink message, and triggering the terminal device to send data to be executed to the bottom layer.

[0138] Specifically, in the above step S12, after determining the corresponding group index, the terminal device can execute the predefined operation corresponding to the group.

[0139] For example, specific operations to be performed by different device groups can be predefined, and the correspondence between these groups and terminal device actions can be pre-stored in the terminal device. After calculating the current group index, the terminal device can determine the specific operation to be performed based on this relationship. In this case, the terminal device group index and / or terminal device identifier can be temporary.

[0140] Exemplarily, or alternatively, the resource allocation information may carry instruction information of specific operations that the specified device group needs to perform.

[0141] For example, corresponding uplink resource data can be pre-configured for different groups of terminal devices, and the corresponding mapping data and resource information can be stored in the terminal device. After the terminal device determines the current grouping result, it can further determine the corresponding uplink resource based on the grouping result. The above-mentioned uplink resource data can include uplink time domain resources and / or frequency domain resources, signal transmission power, coding modulation method, etc. configured for different terminal device groups.

[0142] For example, for different time-frequency domain resources, the terminal device can use the group index as the calculation input parameter for the sending time and / or sending frequency resources to realize the discretization of the terminal device's sending time / frequency domain resources. Alternatively, for different coding modulation modes, the terminal device can use the group index as the calculation input parameter for coding modulation, and different groups obtain different coding modes to realize the use of different coding modulation modes when the terminal device sends uplink signals. For different transmission powers, different device groups can use different signal transmission powers; for example, the terminal device uses the group index as the calculation input parameter for the transmission power, and different device groups obtain different signal transmission power parameters to realize the use of different powers when the terminal sends.

[0143] Alternatively, configuring different uplink resource data for each device group may also be to configure the uplink resources of some device groups to be empty and temporarily stop sending uplink signals, thereby enabling some device groups to send uplink signals and some device groups to not send uplink signals.

[0144] Exemplarily, the uplink message triggered by the terminal device feedback can be an uplink signal sent by the terminal device to the network side, and the uplink signal can be used to notify the network side that the terminal device has received the access control signal and made feedback. Alternatively, the uplink message triggered by the terminal device can also include the grouping index of the terminal device, the terminal device identification, etc. For example, in the application scenario of a smart warehouse, when counting the number of devices, the network side can broadcast resource allocation information, and each terminal device can feedback an uplink message to the network side after calculating the grouping result of the device, and the uplink message carries the grouping result of the terminal device, terminal identification information, and parameters such as the working status. Alternatively, the terminal device can be triggered to send uplink data to the network side, and the uplink data can include more data content of the terminal device; for example, device status information, device log data, etc.

[0145] Exemplarily, triggering the terminal device to perform an access operation may be triggering the terminal device to perform random access.

[0146] Exemplarily, the terminal device is triggered to send data to be executed to the bottom layer, wherein the data to be executed may be business data sent to the bottom layer; or, it may be specific action data that the bottom layer needs to execute, and the action data is executed by the bottom layer.

[0147] In some exemplary embodiments, receiving an access control signal indicating resource allocation information includes: receiving an access control signal indicating resource allocation information in response to at least one stimulation signal.

[0148] Specifically, the network side can first send one or more excitation signals to the terminal device to power it, and then send grouping resource allocation information to the terminal device to group the terminal devices. The terminal device can first receive one or more excitation signals from the network side to power it, then receive the resource allocation information, calculate the corresponding grouping results, and execute the predefined operations for the corresponding services.

[0149] In some exemplary embodiments, the access control signal includes an excitation signal carrying the resource allocation information.

[0150] The response to receiving an access control signal for indicating resource allocation information and determining the grouping information corresponding to the terminal device based on the resource allocation information includes: receiving the excitation signal and parsing the excitation signal to obtain the resource allocation information carried by the excitation signal; and determining the grouping information corresponding to the terminal device based on the resource allocation information.

[0151] Specifically, the network side can carry resource allocation information in the excitation signal. When the terminal device receives the excitation signal and realizes power supply, it parses the excitation signal, extracts the resource allocation information carried therein, calculates the corresponding grouping result based on the resource allocation information, and feeds back an uplink message to the network side.

[0152] In some exemplary embodiments, the resource allocation information includes: an excitation signal.

[0153] The receiving an access control signal indicating resource allocation information, and determining grouping information corresponding to the terminal device based on the resource allocation information, includes:

[0154] receiving at least one of the excitation signals;

[0155] Based on a mapping relationship between the excitation signal and the grouping information, the grouping information is determined according to the received excitation signal.

[0156] Specifically, a correspondence between excitation signals and resource allocation information can be predefined, and the excitation signals can be used to represent the resource allocation information. Different combinations of excitation signals can be used to represent different resource allocation information contents. The different excitation signal combinations can include combinations of different excitation signal types, combinations of excitation signals with different transmission frequencies, and the like.

[0157] For example, different types of excitation signals or combinations of excitation signals can be used to represent different values ​​of the number of packets. Specifically, the network side uses a method of cyclically sending multiple excitation signals, and the terminal device obtains the number of packets by identifying the type of excitation signal.

[0158] Alternatively, the number of excitation signals within a preset period can be used to represent the number of packets. The network can continuously send multiple excitation signals at predetermined time intervals within a predetermined time period; the terminal device calculates the number of excitation signals sent at predetermined time intervals within the predetermined time period to obtain the number of packets. The multiple excitation signals can be of the same type or different types.

[0159] Alternatively, multiple different types of excitation signals can be sent sequentially within a predetermined timeframe, with no time limit imposed on the excitation signal transmission interval. The terminal device determines the number of packets based on the number of excitation signals received. Alternatively, the network can send excitation signals in a cyclical manner, with the terminal device calculating the number of packets based on the types of excitation signals received within the predetermined timeframe.

[0160] In some exemplary embodiments, the access control signal includes: system information carrying the resource allocation information.

[0161] Referring to FIG4 , the method further includes:

[0162] Step S41, the terminal device determines corresponding group information according to the received system message;

[0163] Step S42: In response to the uplink service to be processed, corresponding uplink resource information is determined according to the grouping information, and an uplink message corresponding to the uplink service to be processed is sent to the network device based on the uplink resource information.

[0164] Specifically, the IoT includes some highly capable terminal devices that can receive system information broadcast by the network, select appropriate resources based on the system information configuration, and proactively send uplink signals based on the terminal devices' actual business needs. The network periodically broadcasts system information, and the terminal devices receive it and obtain network packet information. They can then proactively trigger the transmission of uplink data based on business needs, without the need to respond to downlink network signals in real time to trigger subsequent actions.

[0165] In some exemplary embodiments, referring to FIG5 , the method further includes:

[0166] Step S51, in response to a next round of access control signal, comparing the grouping information of the terminal device with the resource allocation information corresponding to the next round of access control signal; wherein the next round of resource allocation information is used to indicate the terminal device that performs the predefined operation;

[0167] Step S52: determining whether to execute a predefined operation corresponding to the grouping information according to the comparison result of the grouping information.

[0168] Specifically, the network can send one or more rounds of downlink messages based on actual service needs. Each round of messages can indicate different device groups, different devices within the same device group, or different IoT devices in different device groups to feedback uplink messages. Terminal devices can receive multiple rounds of downlink messages, parse each message, and respond.

[0169] For example, the terminal device determines that the corresponding group index is 1 according to the first round of resource allocation information, triggering feedback of uplink information; and triggering random access according to the target terminal identification information included in the second round of resource allocation information.

[0170] In some exemplary embodiments, the resource allocation information includes: secondary grouping information; the method further includes: determining uplink resource information corresponding to the terminal device in the group according to the secondary grouping information, and accessing the network based on the uplink resource information.

[0171] Specifically, the access control signal may also include secondary grouping information, which may be used to instruct the terminal device to perform secondary grouping after determining the corresponding group and to configure corresponding uplink resources for each secondary group. A secondary group may include one or more terminal devices.

[0172] For example, if multiple devices are divided into the same group, the devices may interfere with each other when sending uplink signals, resulting in the base station being unable to receive them correctly. It is also possible that the strong signal among multiple uplink signals can be received by the base station, but the weak uplink signal cannot be received by the base station, resulting in some devices not being counted by the network. To solve this problem, for the network side, secondary groups can be pre-configured for different device groups, and each secondary group can be allocated multiple sets of uplink resources; and the number of uplink resources can be greater than or equal to the number of terminal devices in the device group, so that each terminal device can use one uplink resource to access the network and perform specific services, thereby avoiding the problem of interference between uplink signals.

[0173] Specifically, the network can send secondary grouping information (i.e., information indicating secondary grouping) to the terminal via the air interface. After receiving the grouping information, the terminal calculates the corresponding uplink transmission resources and then performs subsequent actions. The secondary grouping information may include uplink transmission resources allocated to each terminal device. Furthermore, the uplink transmission resources may include multiple sets of uplink transmission resources, the specific number of which may be configured by the network for the device. Specifically, the number of uplink transmission resources may be greater than or equal to the number of terminal devices. If a terminal device successfully accesses the network using one set of uplink transmission resources, subsequent resources will no longer trigger subsequent actions. If the terminal device fails to access, subsequent resources will continue to trigger subsequent actions. For example, a group includes three uplink resources and there are two terminal devices in the group. The first terminal device successfully accesses the network using the first set of uplink resources, and the second terminal device successfully accesses the network using the second set of uplink resources. However, the network cannot detect received power on the third set of resources, indicating that no other devices in the group have accessed. The network can carry group resource configuration information in the access control signal. This group resource configuration information can be used to describe the multiple uplink resources available to the terminal devices in the group. Each terminal device may select uplink resources to access the network in a random manner.

[0174] In some exemplary embodiments, the access control signal includes: a first access signal and a second access signal; wherein the first access signal is used to indicate group information, and the second access signal is used to indicate a target group index;

[0175] 6 , the receiving an access control signal indicating resource allocation information and determining group information corresponding to the terminal device based on the resource allocation information includes:

[0176] Step S61: receiving the first access signal, and determining a group index corresponding to the terminal device according to the first access signal;

[0177] Step S62: Receive the second access signal, and determine whether the terminal device performs a corresponding predefined operation according to the second access signal.

[0178] Specifically, the access control signal sent by the network may include two sub-signals, sent sequentially. The first access signal indicates packet information, such as the number of packets; the second access signal indicates a specific target packet index. A terminal device may first receive the first access signal sent by the network and, based on this signal, calculate the packet information to obtain the corresponding packet index. The terminal device may then receive the second access signal sent by the network, which may explicitly or implicitly indicate the target packet index. Upon determining that the corresponding packet index is consistent with the currently indicated target packet index, the terminal device may access the network.

[0179] In some exemplary embodiments, when determining to perform a predefined operation according to the second access signal, the method further includes: determining a network access order of the terminal devices within the corresponding group based on a preset rule.

[0180] Specifically, for multiple terminal devices in a group, network access execution measurements can be pre-configured so that each terminal device can access the network in a certain order. For example, each terminal device can be configured with a counter and a random number generator, and the access order of each terminal device can be determined based on a binary tree random access method.

[0181] Specifically, the terminal device can be configured with a counter of at least 8 bits and a generator of random numbers 0 or 1. 1) After the terminal device receives the access control signal from the network side, it obtains the corresponding group number signal. If the group information corresponding to the terminal device is consistent with the currently indicated group number index, the terminal sets the counter to 0 and starts the random number generator. For devices that generate a random number of 1, the counter is incremented by 1; for devices that generate a random number of 0, the counter remains unchanged, and subsequent actions (i.e., network access actions) are triggered. 2) If the terminal device does not receive a successful response from the base station, if the counter is not equal to 0, the counter is incremented by 1; if the counter is equal to 0, the random number generator is started. For devices that generate a random number of 1, the counter is incremented by 1; for devices that generate a random number of 0, the counter remains unchanged, and subsequent actions are triggered at the next resource location in the group. 3) If the terminal receives a successful response from the base station, and the received terminal identifier is consistent with the current terminal, the terminal access is successful, and subsequent actions will no longer be triggered in this group. 4) If the terminal receives a successful response from the base station, but the received terminal identifier is inconsistent with the current terminal; or if the terminal receives a successful response from the base station, but the response does not include the terminal identifier; in these cases, the counter is decremented by 1, and the terminal whose counter is 0 then triggers subsequent actions at the next resource location within the group. The network controls the terminals to complete access sequentially by sending a successful response message without the terminal identifier, avoiding conflicts. The network can estimate the maximum counter value generated by the device and trigger all possible terminals to access by sending multiple successful response messages without the terminal identifier, thus avoiding missed counts.

[0182] In some exemplary embodiments, an Aloha algorithm may also be used to implement access to terminal devices and avoid collisions.

[0183] In some exemplary embodiments, executing a predefined operation corresponding to the grouping information according to the terminal device includes: receiving a network response configuration message, and configuring a response strategy of the terminal device to the access control signal after accessing the network based on the network response configuration message.

[0184] Specifically, the terminal device can receive a network response configuration message sent by the network side, which can include the silent period after the terminal device accesses the network. The network side can pre-configure the silent period length information after the terminal device accesses the network. For example, after the terminal successfully accesses the network, the network instructs the terminal to enter a silent period, that is, no longer respond to the network signal within the configured time length. In this way, in the next round of the network sending packet information to the terminal through the air interface, after the terminal receives the packet information, the silent period terminal no longer performs subsequent actions, and the non-silent period terminal continues to calculate the corresponding uplink transmission resources, and then performs subsequent actions. In this way, the network triggers multiple rounds until no device access is detected in each group, and it can be determined that the group will not be missed.

[0185] In some embodiments, the access control signal comprises the network response configuration message.

[0186] For example, the network side can configure the terminal silence duration in the access control signal, and can add the corresponding terminal identifier in the access control signal, so that after the terminal device accesses the network, the subsequent actions that can be performed for the terminal selected by the network can be: the terminal no longer responds to the network's paging within a certain period of time, thereby reducing interference with the uplink signals of other terminals in the group and facilitating the network to complete the paging operations of other terminals in the group.

[0187] Alternatively, in some embodiments, the terminal device identifier and the corresponding silence duration may also be added to the second access message.

[0188] In some embodiments, a method for accessing a passive IoT device is provided, which can be used for a network-side device of the IoT. As shown in FIG7 , the method can include the following steps:

[0189] Step S71, determining resource allocation information corresponding to the service to be processed;

[0190] Step S72: Send an access control signal to the terminal device.

[0191] The access control signal is used to indicate resource allocation information, and the resource allocation information is used to determine the grouping information corresponding to the terminal device and perform a predefined operation corresponding to the grouping information.

[0192] In some exemplary embodiments, the access control signal includes: an excitation signal.

[0193] The sending of the access control signal includes: sending at least one excitation signal corresponding to the resource allocation information based on a mapping relationship between the excitation signal and the grouping information.

[0194] In some exemplary embodiments, the sending of the access control signal includes: sending an excitation signal carrying the resource allocation information, so that the terminal device parses the excitation signal to obtain the resource allocation information.

[0197] Step S82: The terminal device receives the access control signal, determines corresponding group information based on the resource allocation information, and executes a predefined operation corresponding to the group information.

[0198] In the method provided in the embodiment of the present disclosure, the network device sends group information to the terminal through the air interface, and the terminal performs subsequent actions in the manner indicated by the group information. The group information may include the number of groups, and the terminal calculates the group to which it belongs according to the number of groups and performs subsequent actions; or the group information may include the number of groups and the group number index, and the terminal calculates the group to which it belongs according to the number of groups, determines that the received group number index is equal to the group to which it belongs, and performs subsequent actions; or the group information may also include the number of groups, the group number index and the terminal identification information. On the basis of the above operations, it is further determined whether the received terminal identification information is consistent with the terminal device and whether the terminal has responded before, and the corresponding uplink signal transmission method is executed. For the terminal device, the terminal calculates the group to which it belongs according to the group information, and can further determine the uplink resources according to the group to which it belongs. This method can realize group management of terminal devices, can realize the reflection of uplink signals of IoT terminal groups, reduce the number of uplink signals received by the network at one time, reduce interference between signals, and improve reception performance.
