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

[0092] In some embodiments, ambient IoT devices can communicate based on backscatter technology. For example, an ambient IoT (A-IoT) device can adjust the matching between the receiving antenna and the impedance according to the information to be transmitted, thereby enhancing the reflection of the incident RF signal. The device can then modulate the data to be transmitted onto the reflected signal, thereby completing the transmission of the data via the reflected signal.

[0093] In some embodiments, when the ambient IoT device communicates in a cellular network (also referred to as a mobile network or a wireless network), the communication between the ambient IoT device and the network device can be implemented based on one of the following two architectures.

[0094] Architecture 1: Environmental IoT devices and network devices directly receive and transmit uplink and downlink data.

[0095] Architecture 2: The environmental IoT devices and network devices indirectly receive and transmit uplink and downlink data, and the intermediate nodes can be responsible for forwarding the uplink and downlink data.

[0096] The intermediate node includes at least one of the following: a relay, a terminal, a repeater, and an Integrated Access Backhaul (IAB) node.

[0097] In some embodiments, environmental IoT devices may include three types: Type A, Type B, and Type C.

[0098] Among them, type A environmental IoT devices have no energy storage and no independent signal generation / amplification function, that is, backscatter transmission.

[0099] Type B IoT devices have energy storage but no independent signal generation capability, i.e., backscatter transmission. Utilization of stored energy may include amplification of reflected signals.

[0100] Type C IoT devices have energy storage and independent signal generation, i.e., active radio frequency (RF) components for transmission.

[0101] In some embodiments, to support data transmission between ambient IoT devices, a device in the network needs to have at least one of the following functions:

[0102] The Energy Source (ES) function can be applied to IoT devices in the above-mentioned Type B and Type C environments.

[0103] The downlink transmission function can send indication information to the environmental IoT device, thereby triggering the uplink transmission of the environmental IoT device.

[0104] The Continuous Wave (CW) excitation function can be used for Type A and Type B ambient IoT devices mentioned above. Ambient IoT devices can achieve uplink transmission through backscatter excitation, which can actually be a source of energy. The ambient IoT device can receive and store the excitation.

[0105] The uplink receiving function can receive uplink information sent by environmental IoT devices through backscattering, or receive uplink information actively transmitted by environmental IoT devices.

[0106] In some embodiments, a device having at least one of the above-mentioned energy source function, downlink transmission function, excitation function, and uplink reception function may be a network device, a terminal, an intermediate node, an environmental Internet of Things server, etc., wherein a device may have only one of the above-mentioned functions, or may have multiple of the above-mentioned functions.

[0107] An Ambient IoT server is a service device or computing platform used to manage, process, and store the business data collected from Ambient IoT devices in the surrounding environment. For example, it can be a physical server or a virtual server, located locally (for example, in a smart home system) or in the cloud. It can provide services such as data processing and storage, and can also implement other functions such as user interfaces, data visualization, remote access, and integration with third-party services or applications.

[0108] In some embodiments, when a network device communicates with an ambient IoT device, three types of commands may exist: Select, Inventory, and Access. Inventory commands primarily consist of five types: Query, QueryAdjust, QueryRep, Acknowledge, and NAK.

[0109] After receiving a valid Query command, each environmental IoT device selected by the set criteria generates a random number (similar to rolling a dice), and each environmental IoT device whose random number is zero will generate a response (send back a temporary password RN16, which is a 16-bit random number) and move to the Reply state; environmental IoT devices that meet other conditions will change certain attributes and flags, thereby exiting the environmental IoT device group, which helps reduce duplicate identification.

[0110] After receiving a valid QueryAdjust command, each environmental IoT device generates a random number, and other operations are the same as receiving a Query command.

[0111] After receiving a valid QueryRep command, the environmental IoT device only decrements the original random number of each environmental IoT device in the environmental IoT device group by one, and other operations are the same as receiving a Query command.

[0112] Only a single environmental IoT device can receive a valid ACK command (using the above-mentioned RN16 or handle, which is a 16-bit random number that temporarily represents the tag identity).

[0113] After receiving the NAK command, the environmental IoT device will switch to the Arbitrate state except for the Ready or Killed states where it remains in its original state.

[0114] In some embodiments, environmental IoT devices can communicate in a cellular network based on some services. For example, a receiver can initiate an inventory service, thereby triggering each environmental IoT device to report data, such as reporting the data to a network device, which is then sent to the receiver by the network device. Alternatively, the environmental IoT device can also spontaneously trigger data reporting.

[0115] The data reported by the environmental Internet of Things device may include, for example, the identification of the environmental Internet of Things device, the data perceived by the environmental Internet of Things device, the data stored in the environmental Internet of Things device, etc.

[0116] Communication services for ambient IoT devices differ from traditional communication services in that, because they primarily use backscatter technology for uplink transmission, they can function as tags within the IoT. Consequently, the amount of data transmitted per uplink is very small. Furthermore, communication services typically target multiple ambient IoT devices. For example, the first service typically involves inventorying multiple ambient IoT devices. To comprehensively capture data perceived by these devices, multiple rounds of data reporting can be triggered from multiple devices.

[0117] For traditional communication services, network equipment performs resource management mainly based on the amount of data used by users in the communication services.

[0118] However, based on the above analysis, it can be seen that in the communication business of environmental Internet of Things devices, it generally involves multiple environmental Internet of Things devices sending data, and the amount of data sent by each environmental Internet of Things device is very small. The network device needs to communicate with each environmental Internet of Things device.

[0119] If network devices still perform resource management based on the amount of data sent by environmental IoT devices, on the one hand, it is necessary to count the amount of data sent by a large number of environmental IoT devices, and the complexity of the statistical operation is relatively high; on the other hand, since the amount of data sent by each environmental IoT device is small, the statistics will determine that the amount of data involved in the business is relatively small, but in fact the network devices need to communicate with each environmental IoT device, so the overhead caused to the network devices is relatively large. Therefore, the data volume cannot accurately represent the overhead caused by the environmental IoT devices in the network, and then the accuracy of resource management based on data volume is relatively poor.

[0120] FIG2 is an interactive schematic diagram showing a method for sending information according to an embodiment of the present disclosure.

[0121] As shown in FIG2 , the information sending method may include the following steps:

[0122] In step S201, the first node sends service information related to the environmental Internet of Things device to the second node.

[0123] In some embodiments, the first node may record service information related to the ambient IoT device and then send the recorded service information related to the ambient IoT device to the second node. In other embodiments, the first node may obtain service information related to the ambient IoT device from other network elements or nodes and send the obtained service information related to the ambient IoT device to the second node.

[0124] In some embodiments, the service information is used by the second node for resource management.

[0125] In step S202, the second node can perform resource management based on the service information, such as allocating resources, adjusting resources, counting resources, deducting resources, adding resources, etc. The resources may include time domain resources, frequency domain resources, remaining traffic, fees, etc.

[0126] In some embodiments, the second node performs resource management based on the service information, where the resource management may include at least one of the following: allocating time domain resources and / or frequency domain resources to the services of the ambient IoT devices, adjusting the time domain resources and / or frequency domain resources already allocated to the services of the ambient IoT devices, and billing the services of the ambient IoT devices. In some embodiments, for example, the second node may perform A-IoT system billing based on the service information sent by the first node.

[0127] It should be noted that the object for resource management by the second node based on service information can be the initiator of the ambient IoT device's services. For example, if the ambient IoT device's services include a first service, the second node can bill the initiator for the first service based on the service information received from the first node. Of course, the initiator of the ambient IoT device's services can also be the first node itself.

[0128] Among them, the first business can be an inventory business or other business command operations. For example, other business command operations can be reading data from an environmental Internet of Things device, or writing data to an environmental Internet of Things device, etc. This disclosure does not limit this.

[0129] In some embodiments, the service information related to the environmental Internet of Things device can be used to represent the information of services provided by the network to the environmental Internet of Things device when the environmental Internet of Things device communicates in the network.

[0130] In some embodiments, the service information includes at least one of the following:

[0131] Identification information of environmental IoT device-related services;

[0132] The lifecycle of services related to environmental IoT devices;

[0133] Frequency of services related to environmental IoT devices;

[0134] rounds of services related to environmental IoT devices;

[0135] Resource management unit for environmental IoT device-related services;

[0136] The number of IoT devices in the environment.

[0137] For example, environmental IoT device-related services may include services provided by the network for environmental IoT devices, such as services for environmental IoT devices in the network.

[0138] Take the environmental IoT device-related services including the first business for environmental IoT devices in the network, resource management including billing as an example.

[0139] For example, the identification information of the environmental Internet of Things device-related services may include the identification of the first business. Based on the identification information, the second node may determine that the business performed for the environmental Internet of Things device is the first business, so that the second node may charge the communication operation of the environmental Internet of Things device as the first business, rather than charging it as other businesses.

[0140] For example, the cycle of the environmental Internet of Things device-related service may include the cycle T of the first business operation (such as an inventory operation) in the first business. The second node may determine that the cycle of the first business operation performed on the environmental Internet of Things device is T, so that the second node may bill the first business according to the cycle T of the first business operation. For example, the longer the cycle T, the higher the billing.

[0141] For example, the frequency of an ambient IoT device-related service may include the frequency f of a first service operation within the first service. The second node may determine the frequency of the first service operation performed on the ambient IoT device as f, and thus the second node may charge the first service based on the frequency f of the first service operation. For example, the higher the frequency f, the higher the charge. In this embodiment, the frequency f can also be understood as the frequency. That is, the more frequent the first service operation, the higher the charge.

[0142] For example, the round number of an environmental IoT device-related service may include round k of a first service operation in a first service. The second node may determine that the round number of the first service operation performed on the environmental IoT device is k (for example, when performing the first service operation on n environmental IoT devices, performing the first service operation once on each environmental IoT device is counted as one round). The second node may then charge the first service according to round k of the first service operation. For example, the greater the number of rounds k, the higher the charge. This process may be independent of the service data volume of the first service operation. For example, in some embodiments, the round number of the first service operation is 3, the total data volume is A, and the round number of the second service operation is 2, the total data volume is B, and B>A. The charge for the first service operation may be higher than the charge for the second service operation. For example, the round number of an environmental IoT device-related service may include the billing unit of the environmental IoT device-related service, such as RMB (e.g., yuan, jiao, fen), US dollars, euros, etc., so that the second node may charge the first service according to this billing unit.

[0143] For example, the round of environmental IoT device-related services may include the number n of environmental IoT devices. The second node may determine that the number of environmental IoT devices targeted by the first business operation is n, so that the second node may charge the first business according to the number n of environmental IoT devices. For example, the greater the number n, the higher the charge.

[0144] It can be seen that according to the embodiment of the present disclosure, the first node sends the service information related to the environmental Internet of Things device to the second node, and the second node can perform resource management based on the service information related to the environmental Internet of Things device. Compared with resource management based on data volume, the resource management cost in this embodiment is more predictable because the resources that need to be managed (such as billing) for each environmental Internet of Things device each time it transmits data are fixed, and there will be no large cost fluctuations in resource management due to slight changes in the amount of data. In addition, for service providers, there is no need to track and count the amount of data sent by a large number of environmental Internet of Things devices, so the logic of resource management is simpler and easier to implement and manage.

[0145] In some embodiments, the first node may include at least one of the following:

[0146] A network device, an environmental Internet of Things server, an intermediate node (such as the intermediate node in the framework 2 of the above embodiment), or any device that can determine service information related to an environmental Internet of Things device and send the service information related to the environmental Internet of Things device to the second node.

[0147] In some embodiments, the second node may be selected from at least one of the following:

[0148] Network devices, environmental IoT servers, and any device capable of resource management (e.g., devices capable of statistical billing).

[0149] For example, the second node is a network device and the first node is an intermediate node. The network device can perform a first business operation on the environmental IoT device through the first node, and the first node can determine the first business operation.

[0150] In some embodiments, the terminal may send service information to the second node according to the first information.

[0151] For example, the first information includes at least one of the following:

[0152] Storage space information;

[0153] Data volume information;

[0154] Round information;

[0155] Frequency information;

[0156] Regional information;

[0157] Time information;

[0158] Signal strength information.

[0159] It should be noted that the first information is not limited to the above-mentioned types, and may also include other information, such as number information, that is, the number of times the first node performs the first business operation on the environmental Internet of Things device. Unlike the rounds, executing the first business operation once for each of the n environmental Internet of Things devices is counted as one round, but executing the first business operation once for each of the n environmental Internet of Things devices is counted as n times.

[0160] In some embodiments, the storage space information includes at least one of the following:

[0161] The remaining storage space of the first node;

[0162] The storage space used by the first node;

[0163] Storage space threshold.

[0164] For example, take the example where the storage space information includes the remaining storage space and the storage space threshold of the first node.

[0165] The first node may send service information related to the environmental Internet of Things device to the second node when the remaining storage space is less than the storage space threshold; or, the first node may send service information related to the environmental Internet of Things device to the second node when the remaining storage space is equal to the storage space threshold; or, the first node may send service information related to the environmental Internet of Things device to the second node when the remaining storage space is greater than the storage space threshold.

[0166] For example, the first node sends service information related to the ambient IoT device to the second node when the remaining storage space is equal to the storage space threshold. If the storage space threshold is 0, the first node can send service information related to the ambient IoT device to the second node when the remaining storage space is 0, that is, when the first node's storage space is full. This helps avoid the situation where the first node continues to obtain service information related to the ambient IoT device after the storage space is full, resulting in the deletion of the stored service information related to the ambient IoT device.

[0167] It should be noted that the storage space threshold may be determined based on a protocol agreement, or may be indicated by the second node. The present disclosure does not limit the manner of determining the storage space threshold.

[0168] In some embodiments, the region information includes at least one of the following:

[0169] Information about the area where the first node is located;

[0170] Information about the area to which the first node will move.

[0171] It should be noted that at least one of the information about the area where the first node is located and the information about the area to which the first node is to move can be determined based on a protocol agreement, or can be indicated by the second node. The present disclosure does not limit the method of determining the information about the area where the first node is located and the information about the area to which the first node is to move.

[0172] For example, information about the area where the first node is located can be used to indicate whether the area where the first node is located supports the first node sending service information related to the environmental Internet of Things device to the second node.

[0173] For example, information about the area to which the first node is to move can be used to represent whether the area to which the first node is to move supports the first node sending service information related to the environmental Internet of Things device to the second node.

[0174] Regarding the area where the first node is located, the area to which the first node is to move, the granularity of the area can be a cell, a tracking area, or other granularities, which is not limited in the present disclosure.

[0175] For example, the area information includes information about a first cell to which the first node is to move. The first cell may include at least one of the following: a cell to be selected by the first node (e.g., a cell to be selected in a non-connected state); a cell to be reselected by the first node (e.g., a cell to be reselected in a non-connected state); and a cell to which the first node is to be handed over (e.g., a cell to be handed over in a non-connected state).

[0176] The information about the first cell to which the first node is to move may include a support capability of the first cell, where the support capability is used to represent at least one of the following:

[0177] whether the first cell supports the first node in acquiring service information related to the environmental IoT device;

[0178] Whether the first cell supports the first node sending service information related to the environmental Internet of Things device to the second node.

[0179] In some embodiments, since the first node may be mobile, such as a terminal, it may move out of a current cell and move to another cell, such as the first cell, in some cases.

[0180] The first node sends the service information related to the environmental Internet of Things device to the second node, which requires at least two steps to implement. The first step is that the first node obtains the service information related to the environmental Internet of Things device, and the second step is that the first node sends the service information related to the environmental Internet of Things device to the second node.

[0181] However, due to different capabilities of different cells, some cells support the first node obtaining service information related to the ambient IoT device and / or support the first node sending service information related to the ambient IoT device to the second node. However, some cells do not support the first node obtaining service information related to the ambient IoT device and / or do not support the first node sending service information related to the ambient IoT device to the second node.

[0182] When the first cell does not support the first node obtaining service information related to the environmental Internet of Things device, the first node can no longer obtain service information related to the environmental Internet of Things device when it moves to the first cell, thereby interrupting the operation of the first node obtaining service information related to the environmental Internet of Things device. The first node may delete the service information related to the environmental Internet of Things device that has been obtained, thereby causing the loss of service information related to the environmental Internet of Things device.

[0183] When the first cell does not support the first node sending the service information related to the environmental Internet of Things device to the second node, the first node cannot send the service information related to the environmental Internet of Things device to the second node when it moves to the first cell. Then the first node may delete the service information related to the environmental Internet of Things device that has been obtained, thereby resulting in the loss of the service information related to the environmental Internet of Things device.

[0184] Therefore, in this embodiment, when the first node is about to move to the first cell, if it is determined based on the information of the first cell that the first cell does not support the first node obtaining service information related to the environmental Internet of Things device, and / or does not support sending the service information related to the environmental Internet of Things device to the second node, then before moving to the first cell, for example, in the current cell, the service information related to the environmental Internet of Things device that has been obtained can be sent to the second node, which is conducive to avoiding the loss of the service information related to the environmental Internet of Things device that has been obtained by the first node.

[0185] For example, the first node obtains service information related to the environmental Internet of Things device based on the first service, and sends the service information related to the environmental Internet of Things device to the second node. Then, when the first node determines that the first cell does not support the first service, it can send the obtained service information related to the environmental Internet of Things device to the second node before moving to the first cell, for example, in the current cell.

[0186] In some embodiments, the information of the cell where the first node is located may include a support capability of the cell where the first node is located, where the support capability is used to represent at least one of the following:

[0187] Whether the cell where the first node is located supports the first node in obtaining service information related to the environmental Internet of Things devices;

[0188] Whether the cell where the first node is located supports the first node sending service information related to the environmental Internet of Things device to the second node.

[0189] The information about the area where the first node is located and the area to which the first node will move, where the area is, for example, area A, can be determined based on at least one of the following:

[0190] Whether area A belongs to a predetermined area;

[0191] Broadcast information for area A;

[0192] Broadcast information for areas other than area A;

[0193] The indication information of the second node is used to indicate information of area A.

[0194] In some embodiments, the first node may predetermine an area, such as one area or a set of multiple areas. The manner of predetermining the area includes but is not limited to determination based on a protocol and determination based on an instruction from the second node.

[0195] The predetermined area may support the first node to obtain service information related to the environmental Internet of Things devices and / or support sending the service information related to the environmental Internet of Things devices to the second node. For example, the predetermined area may specifically support an inventory operation.

[0196] For example, the second node may be an environmental IoT server or a network device (eg, a base station), and the second node may indicate the predetermined area to the first node.

[0197] For example, when the first node determines that area A belongs to a predetermined area, the first node can determine that area A supports the first node to obtain service information related to the environmental Internet of Things device, and / or supports sending service information related to the environmental Internet of Things device to the second node.

[0198] When the first node determines that area A does not belong to a predetermined area, the first node may determine that area A does not support the first node to obtain service information related to the environmental Internet of Things device, and / or does not support sending service information related to the environmental Internet of Things device to the second node.

[0199] The first node may determine whether area A belongs to a predetermined area based on an identifier of area A, or may determine whether area A belongs to a predetermined area in other ways, which is not limited in the present disclosure.

[0200] In some embodiments, area A may indicate its own support capabilities in the broadcast information. For example, area A may include the first cell to which the first node is to move.

[0201] The first node can receive the broadcast information of the first cell, and then determine the support capability of the first cell based on the broadcast information, that is, determine whether the first cell supports the first node to obtain service information related to the environmental Internet of Things device, and / or whether it supports sending the service information related to the environmental Internet of Things device to the second node.

[0202] For example, when the first node determines based on the broadcast information of the first cell that the first cell supports the first node to obtain service information related to the environmental Internet of Things device, and / or supports sending the service information related to the environmental Internet of Things device to the second node, then the service information related to the environmental Internet of Things device can be sent to the second node after moving to the first cell.

[0203] When the first node determines, based on the broadcast information of the first cell, that the first cell does not support the first node obtaining service information related to the environmental Internet of Things device, and / or does not support sending the service information related to the environmental Internet of Things device to the second node, then the service information related to the environmental Internet of Things device can be sent to the second node before moving to the first cell.

[0204] In some embodiments, other areas outside area A, such as area B, may indicate the support capability of area A in the broadcast information. For example, area B may include the current serving cell of the first node, and area A may include the neighboring cells of the current serving cell of the first node.

[0205] The first node can receive the broadcast information of area B, and then determine the support capability of area A based on the broadcast information, that is, determine whether area A supports the first node to obtain service information related to the environmental Internet of Things device, and / or whether it supports sending the service information related to the environmental Internet of Things device to the second node.

[0206] In some embodiments, the second node may send indication information to the first node, indicating the support capability of area A to the first node through the indication information. The indication information may be broadcast information (e.g., system information) or unicast information (e.g., proprietary signaling), which is not limited in the present disclosure.

[0207] In some embodiments, the data volume information includes:

[0208] The data volume of service information;

[0209] Data volume threshold.

[0210] For example, the first node can count the amount of data for the recorded service information related to the environmental Internet of Things device. When the data amount of the service information reaches a data amount threshold (for example, greater than or equal to the data amount threshold), the first node can send the service information related to the environmental Internet of Things device to the second node.

[0211] For example, the data volume threshold can be represented by data volume, or by rounds, frequency, number of times, etc.

[0212] It should be noted that the data volume threshold may be determined based on a protocol agreement, or may be indicated by the second node. The present disclosure does not limit the method for determining the data volume threshold.

[0213] In some embodiments, the round information includes:

[0214] rounds of service information;

[0215] Round threshold.

[0216] For example, the rounds of service information may include the rounds in which the network performs the first business operation on multiple environmental Internet of Things devices. The first node may record the rounds in which the network performs the first business operation on multiple environmental Internet of Things devices. When the rounds reach the round threshold (for example, greater than or equal to the round threshold), the first node may send the service information related to the environmental Internet of Things devices to the second node.

[0217] Of course, the first node may send the service information related to the environmental Internet of Things device to the second node when the round does not reach the round threshold, and the present disclosure does not limit this.

[0218] It should be noted that the round threshold may be determined based on a protocol agreement, or may be indicated by the second node. The present disclosure does not limit the manner in which the round threshold is determined.

[0219] In some embodiments, the frequency information includes:

[0220] Frequency of service messages;

[0221] Frequency threshold.

[0222] For example, the frequency of the service information may include the frequency at which the network performs the first business operation on multiple environmental Internet of Things devices. The first node may record the frequency at which the network performs the first business operation on multiple environmental Internet of Things devices. When the frequency and the frequency threshold satisfy a specific relationship (for example, the frequency is equal to the frequency threshold, or the frequency domain is greater than the frequency threshold, or the frequency is less than the frequency domain threshold), the first node may send the service information related to the environmental Internet of Things device to the second node.

[0223] It should be noted that the frequency threshold may be determined based on a protocol agreement, or may be indicated by the second node. The present disclosure does not limit the manner of determining the frequency threshold.

[0224] In some embodiments, the signal strength information includes at least one of the following:

[0225] signal strength of the cell where the first node is located;

[0226] signal strength of neighboring cells of the cell where the first node is located;

[0227] Signal strength threshold.

[0228] For example, the signal strength may include a reference signal received power (RSRP), and the signal strength threshold may include a reference signal received power threshold; for example, the signal strength information may include a reference signal received quality (RSRQ), and the signal strength threshold may include a reference signal received power quality threshold. The representation of the signal strength information is not limited to the above-mentioned RSRP and RSRQ, and may also be represented by other means, which is not limited by the present disclosure.

[0229] Take the example where the signal strength information includes the signal strength and the signal strength threshold of the cell where the first node is located.

[0230] The first node may measure the signal strength of a cell in which it is located (e.g., a cell in which it resides) and compare the measured signal strength with a signal strength threshold. The first node may send service information related to the ambient IoT device to the second node based on the signal strength information, which may include at least one of the following:

[0231] The signal strength of the cell where the first node is located is less than the signal strength threshold, and the service information related to the environmental Internet of Things device is sent to the second node;

[0232] The signal strength of the cell where the first node is located is equal to the signal strength threshold, and the service information related to the environmental Internet of Things device is sent to the second node;

[0233] If the signal strength of the cell where the first node is located is greater than the signal strength threshold, the service information related to the environmental Internet of Things device is sent to the second node.

[0234] Taking the case where the signal strength of the cell where the first node is located is less than the signal strength threshold, the service information related to the environmental Internet of Things device is sent to the second node as an example.

[0235] When the signal strength of the cell where the first node is located is less than the signal strength threshold, the first node will most likely move (for example, switch, reselect) to other cells, but other cells may not necessarily support the first node sending service information related to the environmental Internet of Things device to the second node. If other cells do not support the first node sending service information related to the environmental Internet of Things device to the second node, the first node will not be able to send service information related to the environmental Internet of Things device to the second node after moving to other cells, which may cause the service information related to the environmental Internet of Things device to be lost, affecting the second node's resource management.

[0236] Therefore, in the embodiment of the present disclosure, the first node can send the service information related to the environmental Internet of Things device to the second node when the signal strength of the cell where the first node is located is less than the signal strength threshold, so as to avoid the first node subsequently switching to another cell and thus being unable to send the service information related to the environmental Internet of Things device to the second node, thereby causing the loss of the service information related to the environmental Internet of Things device. In this case, when the signal strength of the cell where the first node is located is greater than or equal to the signal strength threshold, the first node can continue to record the service information related to the environmental Internet of Things device.

[0237] In a further embodiment, during the process of recording service information related to the environmental Internet of Things device at the first node, for example, during one or more rounds of business operations on at least one environmental Internet of Things device, if the signal strength does not meet the signal strength limitation in the above embodiment, the first node may continue to record the service information related to the environmental Internet of Things device until the service information related to the environmental Internet of Things device is recorded, for example, multiple rounds of business operations are completed, and then the service information related to the environmental Internet of Things device is sent to the second node.

[0238] In some embodiments, the time information includes at least one of the following:

[0239] The time when the first node records the service information;

[0240] The length of time the first node has recorded the service information.

[0241] In some embodiments, the first node may record service information related to the environmental Internet of Things device, and may further determine the time when the service information was recorded, and / or may also determine the length of time the service information has been recorded.

[0242] For example, the first node can determine whether the time for recording service information related to the environmental Internet of Things device is the scheduled time. When the time for recording the service information is the scheduled time, the first node can send the service information related to the environmental Internet of Things device to the second node.

[0243] For example, the first node can determine whether the time of recording service information related to the environmental Internet of Things device is within a predetermined time range. When the time of recording the service information is within the predetermined time range, the first node can send the service information related to the environmental Internet of Things device to the second node.

[0244] For example, the first node can determine the duration of time the service information related to the environmental Internet of Things device has been recorded, and whether the relationship between the duration and the duration threshold satisfies a predefined relationship (for example, the duration is greater than the duration threshold, or the duration is equal to the duration threshold, or the duration is less than the duration threshold). When the relationship between the duration and the duration threshold satisfies the predefined relationship, the first node can send the service information related to the environmental Internet of Things device to the second node.

[0245] It should be noted that in the above embodiments, at least one of the scheduled time, scheduled time range, and duration threshold can be determined based on the protocol agreement, or can be indicated by the second node. The present disclosure does not limit the method of determining the scheduled time, scheduled time range, and duration threshold.

[0246] In some embodiments, the first node may receive request information from the second node, where the request information is used to request the first node to send service information to the second node.

[0247] The first node may record service information related to the environmental IoT device and, upon receiving the request information sent by the second node, may send the service information related to the environmental IoT device to the second node. Prior to receiving the request information sent by the second node, the first node may continue to record the service information related to the environmental IoT device, or, based on the various types of first information in the above-described embodiments, may send the service information related to the environmental IoT device to the second node.

[0248] In some embodiments, when the first node is in a non-connected state, the first node triggers connection establishment or connection recovery according to the first information; and then sends service information related to the environmental Internet of Things device to the second node through the established connection or the restored connection.

[0249] For example, the non-connected state includes at least one of the following: an idle state and an inactive state.

[0250] When the first node is in an idle state, the first node can trigger connection establishment according to the first information, thereby establishing a connection with the second node, and sending service information related to the environmental Internet of Things device to the second node through the established connection.

[0251] When the first node is in an inactive state, the first node can trigger connection recovery according to the first information, thereby restoring the connection with the second node, and sending service information related to the environmental Internet of Things device to the second node through the restored connection.

[0252] Among them, the first node can trigger connection establishment or connection recovery based on the first information, and the first information may meet the limitation of the first information in any of the above embodiments (for example, the storage space of the first node is full, for example, the signal strength of the cell where the first node is located is less than the signal strength threshold, for example, the area to which the first node is to move does not support the first node to obtain service information related to the environmental Internet of Things device, and / or, does not support the first node to send service information related to the environmental Internet of Things device to the second node), and the first node triggers connection establishment or connection recovery.

[0253] In some embodiments, when the first node is in a connected state, it can send service information related to the environmental Internet of Things device to the second node based on the first information as described in any of the previous embodiments, or, when the first node is in a connected state, it can immediately send service information related to the environmental Internet of Things device to the second node whenever it obtains service information related to the environmental Internet of Things device.

[0254] In some embodiments, the first node may send capability information to the second node, wherein the capability information is used to indicate that the first node supports sending service information related to the ambient IoT device to the second node.

[0255] The second node can determine, based on the capability information sent by the first node, whether the first node supports sending service information related to the environmental Internet of Things device to the second node based on the first information.

[0256] For example, when the second node determines that the first node supports sending service information related to the environmental Internet of Things device to the second node based on the first information, at least one of the data volume threshold, round threshold, storage space threshold, frequency threshold, signal strength threshold, and area A information in the above-mentioned embodiment can be indicated to the first node, so that the first node can send the service information related to the environmental Internet of Things device to the second node based on at least one of the information.

[0257] However, when the second node determines that the first node does not support sending the service information related to the environmental Internet of Things device to the second node based on the first information, it is not necessary to indicate to the first node any of the data volume threshold, round threshold, storage space threshold, frequency threshold, signal strength threshold, and area A information in the above-mentioned embodiment, which is conducive to avoiding waste of communication resources.
