For example, the first node may include a terminal, and the second node may include a network device 102 and a server.

The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0086] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0087] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0088] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0089] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto.

[0090] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0091] 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.

[0092] 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.

[0093] Architecture 1: Environmental IoT devices and network devices directly receive and transmit uplink and downlink data.

[0094] 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.

[0095] The intermediate node includes at least one of the following: a relay, a terminal, a repeater, and an Integrated Access Backhaul (IAB) node.

[0096] In some embodiments, environmental IoT devices may include three types: Type A, Type B, and Type C.

[0097] Among them, type A environmental IoT devices have no energy storage and no independent signal generation / amplification function, that is, backscatter transmission.

[0098] 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.

[0099] Type C IoT devices have energy storage and independent signal generation, i.e., active radio frequency (RF) components for transmission.

[0100] 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:

[0101] The Energy Source (ES) function can be applied to IoT devices in the above-mentioned Type B and Type C environments.

[0102] The downlink transmission function can send indication information to the environmental IoT device, thereby triggering the uplink transmission of the environmental IoT device.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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).

[0112] 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.

[0113] In some embodiments, in the above construction 2, the intermediate node can forward relevant information of the environmental Internet of Things devices, such as the inventory data of the environmental Internet of Things devices, to the network device.

[0114] However, since the intermediate nodes are mobile, in some cases, the relevant information of the environmental Internet of Things devices cannot be smoothly forwarded to the network devices, resulting in the loss of relevant information of the environmental Internet of Things devices, affecting the communication effect of the environmental Internet of Things devices.

[0115] FIG2 is an interactive schematic diagram showing a method for sending information according to an embodiment of the present disclosure.

[0116] As shown in FIG2 , the information sending method may include the following steps:

[0117] Step S201: The first node obtains relevant information of the environmental Internet of Things devices.

[0118] In some embodiments, the first node obtains relevant information about the ambient IoT device to save the relevant information and avoid loss of the information. For example, the first node may obtain relevant information about the ambient IoT device from the second node. Alternatively, the first node may pre-store relevant information about the ambient IoT device. The second node may be, for example, an Ambient IOT server node. The second node may initiate a first service to at least one ambient IoT device. During this process, the first node acts as an intermediate node and transmits data with the second node. For example, the first node may perform a first service operation on at least one ambient IoT device based on the first service initiated by the second node, thereby obtaining relevant information about the ambient IoT device from each ambient IoT device.

[0119] For example, the first business may be an inventory business or other business command operations. For example, other business command operations may be reading data from an environmental IoT device or writing data to an environmental IoT device, etc., which is not limited here.

[0120] It should be noted that the relevant information of the environmental Internet of Things device can be obtained from the environmental Internet of Things device as in the previous embodiment, or can also be pre-stored in the first node.

[0121] In step S202, the first node sends relevant information of the environmental Internet of Things device to the second node.

[0122] In some embodiments, the first node can be the intermediate node in Architecture 2 above, or the first node can be any device capable of forwarding information about an ambient IoT device to the second node. In short, the first node can send information about the ambient IoT device to the second node to avoid information loss due to node or terminal movement, communication interruption, and other reasons.

[0123] In some embodiments, the second node may be a network device, or may be an environmental IoT server.

[0124] In some embodiments, the relevant information of the environmental Internet of Things device may be information that needs to be sent to the second node when the second node performs certain business with the environmental Internet of Things device.

[0125] For example, the relevant information of the environmental Internet of Things device may include information obtained from the environmental Internet of Things device when the second node performs a first business operation on multiple environmental Internet of Things devices (or on a single environmental Internet of Things device), such as first business data. For example, the specific content of the relevant information of the environmental Internet of Things device may include the identifier 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., and this disclosure does not limit this. For example, the specific content of the relevant information of the environmental Internet of Things device may include response information of the environmental Internet of Things device, such as ACK, NAK, and this disclosure does not limit this.

[0126] In some embodiments, a first node transmits information related to an ambient IoT device to a second node. Specifically, the information related to the ambient IoT device may be transmitted to the second node based on the first information. That is, the first node transmits the information related to the ambient IoT device to the second node only when specific conditions are met. Alternatively, the first node may transmit the information related to the ambient IoT device to the second node periodically or aperiodically. The specific content of the first information will be described in detail below.

[0127] According to an embodiment of the present disclosure, the first node can send relevant information of the environmental Internet of Things device to the second node based on the first information, without having to wait until the business performed by the environmental Internet of Things device is completed before sending the relevant information of the environmental Internet of Things device to the second node. This is conducive to ensuring that the relevant information of the environmental Internet of Things device is sent to the second node in a timely manner, so as to avoid the problem of the relevant information of the environmental Internet of Things device being lost due to being stored in the first node for too long.

[0128] In some embodiments, the first information includes at least one of the following: time information; signal strength information; cell information. Of course, the first information is not limited to these types, and may also include, for example, location information of the first node, which is not limited in this disclosure.

[0129] In some embodiments, the time information includes at least one of the following:

[0130] Time information;

[0131] Time range information;

[0132] Duration information.

[0133] In some embodiments, taking the time information including moment information as an example, for example, the moment information includes moment t0, the first node sends the relevant information of the environmental IoT device to the second node according to the moment information, which may include at least one of the following:

[0134] The first node sends relevant information of the environmental IoT device to the second node before time t0;

[0135] The first node sends the relevant information of the environmental IoT device to the second node at time t0;

[0136] After time t0, the first node sends the relevant information of the environmental Internet of Things device to the second node.

[0137] The time t0 may be an absolute time (e.g., Beijing time), or a relative time, such as a time n (n is an integer greater than or equal to 1) time slots after the time when the first node obtains the relevant information of the environmental IoT device. A time slot unit may be, for example, a frame, a subframe, a time slot, a symbol, a blind detection period, etc., which is not limited in the present disclosure.

[0138] t0 may be determined based on a protocol agreement, or t0 may be indicated by the second node (for example, when sending the first service configuration to the environmental IoT device, it is sent to the first node), or t0 may be determined autonomously by the first node, or t0 may be determined by negotiation between the first node and the second node. The present disclosure does not limit the method for determining t0.

[0139] In some embodiments, taking the time information including a time range as an example, for example, the time range is t1 to t2, or the start time t1 and the duration T1, the first node sends the relevant information of the environmental IoT device to the second node according to the time range, which may include at least one of the following:

[0140] The first node sends the relevant information of the environmental Internet of Things device to the second node within the time range t1 to t2 or t1 to t1+T1;

[0141] The first node sends the relevant information of the environmental Internet of Things device to the second node outside the time range t1 to t2 or t1 to t1+T1. That is, the terminal does not send the relevant information of the environmental Internet of Things device to the second node within the time range t1 to t2 or t1 to t1+T1. Wherein, the above-mentioned moments t1 and t2 can be absolute times (for example, Beijing time), or, moments t1 and t2 can be relative times, for example, t1 is the time when the first node obtains the relevant information of the environmental Internet of Things device as the starting point, and the moment of n (n is an integer greater than or equal to 1) time slot units after the starting point. The time slot unit can be, for example, a frame, a subframe, a time slot, a symbol, a blind detection period, etc., and T1 can be a specific duration, such as 10 seconds, or it can be a multiple of the time slot unit, wherein, for example, the first node can send the relevant information of the environmental Internet of Things device to the second device between the moment t1 and the moment 10 subframes after the moment t1, and the present disclosure is not limited to this.

[0142] At least one of t1, t2, and T1 may be determined based on a protocol agreement, or at least one of t1, t2, and T1 may be indicated by the second node (for example, when sending the first service configuration to the environmental IoT device, it is sent to the first node), or at least one of t1, t2, and T1 may be determined autonomously by the first node, or at least one of t1, t2, and T1 may be determined by negotiation between the first node and the second node. The present disclosure does not limit the method of determining t1, t2, and T1.

[0143] In some embodiments, taking the time information including duration information as an example, for example, the duration is T2, the first node sends the relevant information of the environmental IoT device to the second node according to the duration information, which may include at least one of the following:

[0144] Starting from the time starting point and lasting for T2, the relevant information of the environmental IoT device is sent to the second node;

[0145] Starting from the time starting point and before the duration T2, the relevant information of the environmental IoT device is sent to the second node;

[0146] Starting from the time starting point and lasting for a duration of T2, the relevant information of the environmental Internet of Things device is sent to the second node.

[0147] The duration can be determined based on a timer. For example, if a timer is started at a starting time, and the timer duration is T2, then the duration T2 can refer to when the timer times out, the duration before T2 can refer to before the timer times out, and the duration after T2 can refer to after the timer times out.

[0148] T2 can be determined based on a protocol agreement, or T2 can be indicated by the second node (for example, when sending the first service configuration to the environmental IoT device, it is sent to the first node), or T2 can be determined autonomously by the first node, or T2 can be determined by negotiation between the first node and the second node. The present disclosure does not limit the method of determining T2.

[0149] For example, the time starting point may be when the first node obtains the relevant information of the environmental IoT device; for example, the time starting point may be when the first node receives T2 indicated by the second node. This disclosure does not limit the method for determining the time starting point.

[0150] Based on the above embodiment, the first node can send the relevant information of the environmental Internet of Things device to the second node as quickly as possible based on the time information, which is conducive to avoiding the loss of relevant information of the environmental Internet of Things device and affecting the communication effect of the environmental Internet of Things device.

[0151] In a further embodiment, in the process of the first node obtaining relevant information of the environmental Internet of Things device, for example, in the process of performing one or more rounds of first business operations on at least one environmental Internet of Things device, if the time information does not meet the limitations on the time information in the above embodiments, the first node can continue to obtain relevant information of the environmental Internet of Things device until the relevant information of the environmental Internet of Things device is obtained, for example, the first business operation process is completed, and then the relevant information of the environmental Internet of Things device is sent to the second node.

[0152] In some embodiments, the signal strength information includes at least one of the following:

[0153] signal strength information of the cell where the first node is located;

[0154] Signal strength threshold information.

[0155] Among them, the signal strength threshold information can be determined based on the protocol agreement, or the signal strength threshold information can be indicated by the second node (for example, when sending the first service configuration to the environmental Internet of Things device, it is sent to the first node), or the signal strength threshold information can be determined autonomously by the first node, or the signal strength threshold information can be determined by negotiation between the first node and the second node. The present disclosure does not limit the method for determining the signal strength threshold information.

[0156] For example, the signal strength information may include Reference Signal Received Power (RSRP), and the signal strength threshold information may include a reference signal received power threshold; for example, the signal strength information may include Reference Signal Received Quality (RSRQ), and the signal strength threshold information may include reference signal received power quality. 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.

[0157] 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. In this case, the first node may send relevant information of the ambient IoT device to the second node based on the signal strength information, which may include at least one of the following:

[0158] The signal strength of the cell where the first node is located is less than the signal strength threshold, and the relevant information of the environmental Internet of Things device is sent to the second node;

[0159] The signal strength of the cell where the first node is located is equal to the signal strength threshold, and the relevant information of the environmental Internet of Things device is sent to the second node;

[0160] If the signal strength of the cell where the first node is located is greater than the signal strength threshold, the relevant information of the environmental Internet of Things device is sent to the second node.

[0161] In summary, the first node can determine whether to send relevant information of the environmental IoT device to the second node based on the relative size between the signal strength of the cell where it is located and a specific signal strength threshold.

[0162] Taking the case where the signal strength of the cell where the first node is located is less than the signal strength threshold, the relevant information of the environmental Internet of Things device is sent to the second node as an example.

[0163] When the signal strength of the cell where the first node is located is less than the signal strength threshold, the first node is likely to move (for example, switch, reselect) to other cells, but other cells do not necessarily support the first node sending the relevant information of the environmental Internet of Things device to the second node. If other cells do not support the first node sending the relevant information of the environmental Internet of Things device to the second node, the first node cannot send the relevant information of the environmental Internet of Things device to the second node after moving to other cells, which may cause the relevant information of the environmental Internet of Things device to be lost, affecting the communication effect of the environmental Internet of Things device. Therefore, the first node sends the relevant information of the environmental Internet of Things device to the second node on the cell that supports sending the relevant information of the environmental Internet of Things device to the second node, so as to avoid the subsequent inability to send relevant messages to the second node due to switching, reselection, selection or network environment changes of the cell. Therefore, in the embodiment of the present disclosure, the first node can send the relevant information of 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 subsequent inability to send the relevant information of the environmental Internet of Things device to the second node due to switching to other cells, thereby causing the relevant information of the environmental Internet of Things device to be lost. 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 obtain the relevant information of the environmental Internet of Things device.

[0164] In a further embodiment, in the process of the first node obtaining relevant information of the environmental Internet of Things device, for example, in the process of performing one or more rounds of first business operations on at least one environmental Internet of Things device, if the signal strength information does not meet the limitations on the signal strength information in the above embodiment, the first node can continue to obtain relevant information of the environmental Internet of Things device until the relevant information of the environmental Internet of Things device is obtained, for example, the first business operation process is completed, and then the relevant information of the environmental Internet of Things device is sent to the second node.

[0165] In some embodiments, the cell information includes support capabilities of the first cell, where the support capabilities include at least one of the following:

[0166] whether the first cell supports the first node in acquiring relevant information about the environmental IoT device;

[0167] Whether the first cell supports the first node sending relevant information of the environmental Internet of Things device to the second node.

[0168] In some embodiments, the first cell may be the cell to which the first node is to move, for example, the first cell includes at least one of the following: the cell to which the first node is to select (for example, the cell to be selected in a non-connected state); the cell to which the first node is to reselect (for example, the cell to be reselected in a non-connected state); the cell to which the first node is to switch (for example, the cell to be switched in a non-connected state).

[0169] Since the first node may be mobile, such as a terminal, it may move out of the current cell and move to another cell in some cases. For example, the cell to which the first node is about to move may be referred to as the first cell. This cell may be the same as or different from the current cell.

[0170] The first node sends the relevant information of the environmental Internet of Things device to the second node, which requires the first node to obtain the relevant information of the environmental Internet of Things device and send the relevant information of the environmental Internet of Things device to the second node.

[0171] However, due to different capabilities of different cells, some cells support the first node obtaining relevant information about the environmental IoT device and / or support the first node sending relevant information about the environmental IoT device to the second node. However, some cells do not support the first node obtaining relevant information about the environmental IoT device and / or do not support the first node sending relevant information about the environmental IoT device to the second node.

[0172] When the first cell does not support the first node to obtain relevant information of the environmental Internet of Things device, the first node cannot continue to obtain relevant information of the environmental Internet of Things device when it moves to the first cell, thereby interrupting the operation of the first node to obtain relevant information of the environmental Internet of Things device. Then, the first node may delete the relevant information of the environmental Internet of Things device that has been obtained, thereby causing the loss of relevant information of the environmental Internet of Things device.

[0173] When the first cell does not support the first node sending relevant information of the environmental Internet of Things device to the second node, the first node cannot send relevant information of the environmental Internet of Things device to the second node when it moves to the first cell. Then the first node may delete the relevant information of the environmental Internet of Things device that has been obtained, thereby causing the relevant information of the environmental Internet of Things device to be lost.

[0174] Therefore, in this embodiment, when the first node is about to move to the first cell, if it is determined that the first cell does not support the first node obtaining relevant information of the environmental Internet of Things device, and / or does not support sending relevant information of the environmental Internet of Things device to the second node, then before moving to the first cell, for example, in the current cell, the obtained relevant information of the environmental Internet of Things device can be sent to the second node. This is helpful to avoid the first node being unable to transmit relevant information of the environmental Internet of Things device to the second node after moving to the first cell, thereby causing the loss of relevant information of the environmental Internet of Things device that has been obtained.

[0175] For example, the first node obtains relevant information of the environmental Internet of Things device based on the first service, and sends relevant information of 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 relevant information of the environmental Internet of Things device to the second node before moving to the first cell, for example, in the current cell.

[0176] In some embodiments, the support capability is determined based on at least one of the following:

[0177] whether the first cell belongs to a predetermined area;

[0178] Broadcast information of the first cell;

[0179] Broadcast information of a second cell other than the first cell;

[0180] Indication information of the second node, where the indication information is used to indicate the support capability of the first cell.

[0181] It should be understood that the second node may determine the support capability of the first cell and inform the first node through indication information.

[0182] 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.

[0183] The predetermined area may support the first node in acquiring relevant information about the environmental IoT device and / or support sending relevant information about the environmental IoT device to the second node. For example, the predetermined area may specifically support the first service operation.

[0184] For example, the second node may be an environmental IoT device or a network device (eg, a base station), and the second node may indicate the predetermined area to the first node through information.

[0185] For example, when the first node determines that the first cell belongs to a predetermined area, the first node can determine that the first cell supports the first node to obtain relevant information of the environmental Internet of Things device, and / or supports sending relevant information of the environmental Internet of Things device to the second node, then the relevant information of the environmental Internet of Things device can be sent to the second node after moving to the first cell.

[0186] When the first node determines that the first cell does not belong to a predetermined area, the first node may determine that the first cell does not support the first node obtaining relevant information of the environmental Internet of Things device, and / or does not support sending relevant information of the environmental Internet of Things device to the second node, then the relevant information of the environmental Internet of Things device may be sent to the second node before moving to the first cell.

[0187] The first node may determine whether the first cell belongs to the predetermined area based on the identifier of the first cell, or may determine whether the first cell belongs to the predetermined area in other ways, which is not limited in the present disclosure.

[0188] In some embodiments, the first cell may indicate its own support capability in the broadcast information. For example, the first cell may include a neighboring cell of the cell where the first node is currently located.

[0189] 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 relevant information of the environmental Internet of Things device, and / or whether it supports sending relevant information of the environmental Internet of Things device to the second node.

[0190] 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 relevant information of the environmental Internet of Things device, and / or supports sending relevant information of the environmental Internet of Things device to the second node, then the relevant information of the environmental Internet of Things device can be sent to the second node after moving to the first cell.

[0191] 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 relevant information of the environmental Internet of Things device, and / or does not support sending relevant information of the environmental Internet of Things device to the second node, then the relevant information of the environmental Internet of Things device can be sent to the second node before moving to the first cell.

[0192] In some embodiments, a second cell other than the first cell may indicate the support capability of the first cell in broadcast information, for example, the second cell is the current serving cell of the first node, and the first cell is a neighboring cell of the current serving cell.

[0193] The first node can receive the broadcast information of the second cell, and then determine the support capability of the first cell based on the broadcast information, that is, determine whether the second cell supports the first node in obtaining 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.

[0194] In some embodiments, the second node may send indication information to the first node, indicating the support capability of the first cell to the first node via 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 this disclosure.

[0195] For example, when the first node determines, based on the indication information of the second node, that the first cell supports the first node in obtaining relevant information of the environmental Internet of Things device, and / or supports sending relevant information of the environmental Internet of Things device to the second node, then the relevant information of the environmental Internet of Things device can be sent to the second node after moving to the first cell.

[0196] When the first node determines, based on the indication information of the second node, that the first cell does not support the first node obtaining relevant information of the environmental Internet of Things device, and / or does not support sending relevant information of the environmental Internet of Things device to the second node, then the relevant information of the environmental Internet of Things device can be sent to the second node before moving to the first cell.

[0197] 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 relevant information of the environmental Internet of Things device to the second node through the established connection or the restored connection.

[0198] For example, the non-connected state includes at least one of the following: an idle state and an inactive state.

[0199] 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 relevant information of the environmental Internet of Things device to the second node through the established connection.

[0200] 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 relevant information of the environmental Internet of Things device to the second node through the restored connection.

[0201] Among them, the first node triggers connection establishment or connection recovery according to the first information, which may be that the first information meets the limitation of the first information in any of the above embodiments (for example, the signal strength of the cell where the first node is located is less than the signal strength threshold, for example, the first cell does not support the first node to obtain relevant information of the environmental Internet of Things device, and / or does not support the first node to send relevant information of the environmental Internet of Things device to the second node), and the first node triggers connection establishment.

[0202] In some embodiments, when the first node is in a connected state, it can send relevant information of 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 relevant information of the environmental Internet of Things device to the second node whenever it obtains relevant information of the environmental Internet of Things device.

[0203] In some embodiments, the first node may send capability information to the second node; wherein the capability information is used to indicate whether the first node supports sending relevant information of the environmental Internet of Things device to the second node according to the first information.

[0204] The second node may determine, based on the capability information sent by the first node, whether the first node supports sending relevant information of the environmental IoT device to the second node based on the first information.

[0205] For example, when the second node determines that the first node supports sending relevant information of the environmental Internet of Things device to the second node based on the first information, at least one of the information t0, t1, t2, T1, signal strength threshold, and predetermined area in the above embodiment can be indicated to the first node, so that the first node can send relevant information of the environmental Internet of Things device to the second node based on at least one of the information.

[0206] However, when the second node determines that the first node does not support sending relevant information of 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 information of t0, t1, t2, T1, signal strength threshold, and predetermined area in the above embodiment, which is conducive to avoiding waste of communication resources.

[0207] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0208] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0209] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0210] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
