[0210] 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 (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication processing methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0211] To meet the growing demands of vertical sectors, existing Low Power Wide Area (LPMA) technologies, such as Machine Type Communication (MTC), Narrow Band Internet of Things (NB-IoT), and Reduced Capability (RedCap), can achieve low cost, low power consumption, and large-scale connectivity. However, they still cannot address the following requirements: First, traditional battery-powered devices are not suitable, for example, in extreme environmental conditions (such as high voltage, extremely high / low temperatures, and humid environments); second, maintenance-free devices are required (for example, traditional batteries that do not require replacement); and finally, ultra-low complexity, very small device size or form factor (such as mm thickness), and extended life cycle are required. The Internet of Things that supports ambient power or ambient energy can meet these requirements.

[0212] Low-power IoT communication chips, such as Bluetooth Low Energy (BLE), Long Range Radio (LoRa), or NB-IoT, consume tens or even hundreds of milliwatts of power for both transmission and reception. However, as described in the preceding embodiments, ambient energy harvesting captures only microwatts of energy. Harvesting energy from the environment can power sensor nodes, such as the first device 101, for data transmission and wireless communication. Wireless communication technologies are needed that can reduce communication energy consumption to tens or even below ten microwatts.

[0213] Backscatter Communications is an extremely low-power modulation and transmission technology that uses the principle of backscattering of radio frequency signals. It is a means to realize the intelligent connection of all things. In backscatter communications, since a part of the radio frequency signal, such as electromagnetic waves, will be reflected when it reaches the surface of an object, the passive node as the sending node, such as the first device 101, adjusts the matching between the receiving antenna and the impedance according to the information to be sent, enhances the reflection of the incident radio frequency signal, and modulates the perception data obtained by itself onto the reflected signal to complete the transmission of the data. Compared with other communication technologies, backscatter communications do not require a complex radio frequency structure, reduce the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters, and do not require complex baseband processing. Therefore, it can simplify the terminal design and significantly reduce the cost of terminal nodes.

[0214] In a Radio Frequency Identification (RFID) system using backscatter communication, as shown in FIG. 1g, a receiver sends a radio frequency excitation signal to activate a passive node. The receiver is a RFID reader, corresponding to the network device 102; the passive node is a RFID tag, corresponding to the first device 101. The tag modulates its information onto the radio frequency signal using backscatter communication, and the reader receives the reflected signal of the passive tag and demodulates it to achieve information transmission. The RFID communication process has the following disadvantages: the wireless signal experiences double-path fading, the path loss is large, the effective communication distance is short, and thus the coverage distance is small; single-channel transmission is required; the tag needs to be strictly aligned; there is no power control, etc. It is necessary to integrate 3GPP communication technology to improve the wireless communication performance of RFID technology in the passive Internet of Things.

[0215] In the RFID communication system, as shown in FIG. 1h, from the perspective of use, it is divided into three types of commands: tag selection (Select), inventory (Inventory) and access (Access). Among them:

[0216] The selection command includes: Select command and Challenge command.

[0217] The inventory command includes: Query command, QueryAdjust command, QueryRep command, ACK command, NAK command.

[0218] The access command includes: Req_RN command, Read command, Write command, Kill command, Lock command; optionally, it can also include: Access command, BlockWrite command, BlockErase command.

[0219] In combination with the inventory and access examples shown in FIG. 1i, the command application examples in the inventory process can include:

[0220] (1) After the tag receives a valid Query command, each tag that meets the set standard generates a random number. Each tag with a random number of zero will produce a response, such as sending back a temporary password RN16, RN16 is a 16-bit random number, and is transferred to the Reply state; other tags can change some attributes and flags, and exit the group of tags with zero, which is helpful to reduce repeated identification.

[0221] (2) After the tag receives a valid QueryAdjust command, each tag respectively generates a new random number, and the other behaviors are the same as the Query command.

[0222] (3) After the tag receives a valid QueryRep command, the original random number of each tag in the tag group is reduced by one, and other behaviors are the same as the Query command.

[0223] (4) Only a single tag can receive a valid ACK command, and after receiving it, it sends back the content in the EPC area according to the EPC protocol. The ACK command can use the RN16 or Handle described above. The Handle is a 16-bit random number temporarily representing the identity of the tag.

[0224] (5) After the tag receives a valid NAK command, the tag in the Ready state or the Killed state remains in the original state, and the tag in other states all goes to the Arbitrate state. The states of the tag are shown in FIG. 1h.

[0225] Based on the above description, the tag mobility is not supported in the RFID, such as the mobility behavior in the idle state of the cell selection and the cell reselection type. For the structure of FIGS. 1b and 1c (the UE as an intermediate node under the control of the NW), there is no Radio Resource Control (RRC) state, no mobility (i.e., at least no function similar to cell selection / reselection), no Hybrid Automatic Repeat Request (HARQ), and no ARQ.

[0226] Therefore, for the environmental Internet of Things device, it is necessary to collect the radio waves sent by the network node to obtain energy to drive itself to work. Before obtaining energy, it is usually in the state of power-off or off-network. The periodic location update of the conventional terminal is no longer applicable to the cross-border location update mode. In addition, in the logistics scenario such as the inventory process, it is necessary for the network device 102 to obtain the information of the first device 101 in a timely manner. How to realize the timely update of the information of the environmental Internet of Things device is a problem to be solved.

[0227] The embodiment of the present disclosure provides a communication method, which can realize the information update of the environmental Internet of Things device, such as the timely update of the location information, by the active reporting of the first device 101 or the active inventory registration of the network device 102, so as to update the location information and the transportation state of the device in a timely manner.

[0228] FIG. 2a is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2a, the embodiment of the present disclosure relates to a communication method, and the above method comprises:

[0229] In step S2101, the network device 102 provides energy for the first device 101.

[0230] In some embodiments, in combination with FIG. 1a to FIG. 1f, the first device 101 can be an environmental Internet of Things device. The network device 102 at least has an ES function or a CW function, and provides energy for the first device 101 by providing electromagnetic waves and the like.

[0231] In an example, in a logistics scenario or an inventory process, the first device 101 can be an electronic tag or tag.

[0232] In some embodiments, the first device 101 can be powered by an ES node in the network device 102, or powered by another ES node other than the network device 102, and the network device 102 can control or communicate with the other ES node. The present embodiment does not limit the way the first device 101 obtains energy.

[0233] In some embodiments, the first device 101 obtains energy provided by the network device 102, and is charged or powered on.

[0234] In an example, the first device 101 is in an off state or a network disconnection state before obtaining energy. Before the off state, the first device 101 can access a network, for example, be registered by another network device in an inventory, and the network information of the last network access or the last time the first device 101 accesses the network can be recorded as first network access information.

[0235] In step S2102, the network device 102 sends second network access information to the first device 101.

[0236] In some embodiments, the second network access information includes network information corresponding to the network device 102.

[0237] In some embodiments, the second network access information includes at least one of the following:

[0238] The network name (name) corresponding to the network device 102;

[0239] The network index (index) corresponding to the network device 102;

[0240] The network ID corresponding to the network device 102.

[0241] Among them, the network name, the network index or the network ID can represent the relevant information of accessing the network, such as the location, so that the device position covered by the network can be described according to the network information.

[0242] In some embodiments, the network device 102 can send the second network access information by sending second signaling. Among them, the second signaling is one of the following:

[0243] System information broadcasted by the network device 102;

[0244] Paging message;

[0245] Inventory command.

[0246] In some embodiments, the system information or the paging message broadcasted by the network device 102 can be received by more devices. In combination with the description of the foregoing embodiments, the inventory command can be a Query command in the inventory process.

[0247] In some embodiments, the first device 101 actively acquires or receives the second network access information after being powered on or charged.

[0248] In some examples, the first device 101 acquires the second network access information from a broadcast type command of the system broadcast information type, or acquires the second network access information from paging, or acquires the second network access information from an inventory command such as a Query command.

[0249] In some embodiments, when the first network access information is inconsistent with the second network access information, i.e., the newly acquired network information of the first device 101 does not match the network information of the last serving network, the first device 101 can directly perform step S2104.

[0250] In some embodiments, when the first network access information is inconsistent with the second network access information, i.e., the newly acquired network information of the first device 101 does not match the network information of the last serving network, the first device 101 can perform steps S2103-S2104.

[0251] In some embodiments, the inconsistency or mismatch between the first network access information and the second network access information can be that the network name in the first network access information is different from the network name in the second network access information, or that the network index of the two is different, or that the network identifier of the two is different, as long as one of the above conditions is met.

[0252] In step S2103, the network device 102 sends a first signaling to the first device 101.

[0253] In some embodiments, the first signaling is used for paging devices or querying devices in an inventory process, for example, the first signaling is a paging or a Query command in the inventory process.

[0254] In some embodiments, the first device 101 receives the first signaling.

[0255] In some embodiments, steps S2102 and S2103 can be performed respectively, for example, the network device 102 sends the second network access information through paging, and the first signaling is a Query command.

[0256] In some embodiments, steps S2102 and S2103 can be performed synchronously, for example, the network device 102 sends the second network access information through the first signaling, which can be paging or Query command.

[0257] In some embodiments, step S2103 can be omitted, for example, the first device 101 directly performs step S2104 to report the device information when determining that the first network access information is inconsistent with the second network access information, without receiving the first signaling.

[0258] In some embodiments, the first device 101 performs step S2104 to send the device information of the first device to the network device in response to receiving the first signaling. Alternatively, the device information is sent by the first device 101 after receiving the first signaling, and the first device 101 can perform step S2104 to report the device information after receiving the first signaling, regardless of whether the first device belongs to or does not belong to the device selected in the first signaling. In this embodiment, the first network access information is consistent or inconsistent with the second network access information.

[0259] Optionally, the device selected by the first signaling, i.e., the device determined or selected by the network device 102 through the first signaling, for example, the device paged through paging or the tag selected through the Query command generates a random number.

[0260] In an example, taking the inventory process as an example, the first device 101 can be a tag. The network device 102 sends a Query command, and the tag meeting the set standard is selected to generate a random number. In this example, the first device 101 will actively participate in the inventory process and handshake with the network device 102, regardless of whether the first device 101 belongs to the tag selected by the Query command.

[0261] Step S2104, the first device 101 sends the device information of the first device to the network device 102.

[0262] In some embodiments, the first device 101 can send the device information of the first device to the network device in response to the inconsistency between the first network access information and the second network access information after being charged or powered on. Alternatively, the device information is sent when the first network access information is inconsistent with the second network access information, and the first device 101 can actively send the device information when the newly acquired second network access information is inconsistent with the first network access information of the last time of accessing the network.

[0263] In an example, when the first network access information is inconsistent with the second network access information, the first device 101 can actively access the network device 102, the reference DO traffic includes DO-A (DO autonomous) and device 1, device 2a or device 2c, or DO-A and sensor use case type of traffic, and the first device 101 actively reports the device information.

[0264] In this example, the step S2103 can be omitted.

[0265] In some embodiments, after the first device 101 is powered or powered on, if the newly acquired second network access information is inconsistent with the first network access information of the last time the network is accessed, the first device 101 can handshake with the network device 102 after receiving a first signaling, that is, after step S2103, and actively report the device information after the handshake.

[0266] In some embodiments, the device information includes at least one of the following:

[0267] The device identifier of the first device;

[0268] The purpose of sending the device information;

[0269] The first network access information, which is the network information of the network accessed by the first device 101 last time before sending the device information.

[0270] Optionally, the device identifier can uniquely determine the first device 101.

[0271] Optionally, the purpose of reporting the device information can be that the first device 101 reports to the network device 102, without the need to send uplink according to the inventory command.

[0272] Optionally, the first network access information can include the network name, network identifier or network index of the last or last time accessed network. The network side device corresponding to the first network access information can be different from or the same as the network device 102 sending the signaling.

[0273] In an example, the first device 101 can only report the device identifier of the first device, or report the device identifier of the first device and the purpose.

[0274] In another example, the first device 101 can report the above three device information.

[0275] In some examples, if the first network access information is the same as the second network access information, i.e., the network accessed by the first device 101 last time corresponds to the network device 102, the device information may have been reported in the inventory process. When the first network access information is inconsistent with the second network access information, the network accessed by the first device 101 changes, and new device information needs to be reported.

[0276] In some embodiments, the names of information and the like are not limited to the names described in the embodiments, and the terms of "signal", "message", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", and the like can be replaced with each other.

[0281] In some embodiments, the terms "certain", "preset", "pre-set", "set", "indicated", "any", "first", and the like can be replaced with each other, and "certain A", "preset A", "pre-set A", "set A", "indicated A", "any A", "first A" can be interpreted as A predetermined in a protocol or the like, or A obtained by setting, configuration, or indication, or a specific A, any A, or first A, but are not limited thereto.

[0282] The method according to the embodiments of the present disclosure can include at least one of steps S2101-S2104. For example, the method includes step S2104.

[0283] In some embodiments, step S2101 can be omitted, and in different embodiments, one or more steps can be replaced. For example, the method includes steps S2102-S2104.

[0284] In some embodiments, step S2102 can be omitted, and in different embodiments, one or more steps can be replaced. For example, the method includes steps S2103-S2104, that is, the first device 101 can report device information to the network device 102 after power-on.

[0285] In some embodiments, step S2103 can be omitted, and in different embodiments, one or more steps can be replaced. For example, the method includes steps S2102 and S2104, at this time, the first device 101 can actively access the network and report device information.

[0286] In some embodiments, reference can be made to the other optional implementations described before or after the description corresponding to FIG. 2a.

[0287] In the embodiments of the present disclosure, based on ambient IOT reporting, the position update of the ambient IOT device is realized. The first device 101 can actively report device information, so that the network device 102 can timely learn the access position of the first device 101, to accurately update the position or state of the first device 101.

[0288] FIG. 2b is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2b, the present disclosure relates to a communication method, and the above method includes:

[0289] Step S2201, the network device 102 sends third signaling to the first device 101.

[0290] In some embodiments, the network device 102 and the related implementation of the first device 101 can refer to the description of the aforementioned embodiments, for example, refer to step S2101 in the embodiment of FIG. 2a, which will not be repeated here.

[0291] In some embodiments, the third signaling is used to instruct all devices under the coverage of the network device 102 to report device information.

[0292] In some embodiments, the network device 102 can communicate with multiple environmental Internet of Things devices, for example, the network device 102 can send the third signaling to one or more first devices 101 in a broadcast manner, and the first device receiving the third luggage can report its own device information to the network device.

[0293] In some embodiments, the first device 101 can perform step S2202, i.e., send the device information of the first device to the network device, in response to receiving the third signaling; or in other words, the device information is sent after the first device 102 receives the third signaling, and the first device 101 can perform step S2202 after receiving the third signaling.

[0294] For example, taking the inventory process as an example, the network device 102 can instruct all tags to report device information in response to the third signaling by sending the third signaling. The tag receiving the third signaling needs to perform step S2202.

[0295] In some embodiments, the third signaling is one of the following:

[0296] Polling message;

[0297] Paging message;

[0298] Inventory command.

[0299] In some examples, the third signaling can be a new signaling or sent through an existing signaling. For example, the third signaling is a polling message, or a paging message, or a Query command, and the value of the field corresponding to the “target tag” in the third signaling is configured as “All”; so that all first devices 101 can access the network and perform step S2202. Wherein, the first device 101 can access the network based on the slot-ALOHA manner.

[0300] Step S2202, the first device 101 sends the device information of the first device to the network device 102.

[0301] In some embodiments, the implementation of step S2202 can refer to the implementation of step S2104 in the embodiment of FIG. 2a, which will not be repeated here.

[0302] In some embodiments, the first device 101 can report the device information after receiving the third signaling.

[0303] In some embodiments, before step S2201 or S2202, the first device 101 can be charged or powered on, and the implementation of step S2101 in the embodiment of FIG. 2a is referred to, which is not repeated here.

[0304] The method related to the embodiments of the present disclosure can include at least one of steps S2201-S2202.

[0305] In some embodiments, other optional implementations described before or after the corresponding description of FIG. 2b can be referred to.

[0306] In the embodiments of the present disclosure, the location update of the environmental Internet of Things device is implemented based on network polling. After receiving the third signaling of the network device 102, the first device 101 can report the device information based on the indication of the third signaling, so that the network device 102 can timely learn the access location of the first device 101 to accurately update the location or state of the first device 101.

[0307] FIG. 2c is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2c, the embodiments of the present disclosure relate to a communication method, and the above method includes:

[0308] Step S2301, the first device 101 stores device information.

[0309] In some embodiments, in combination with the description of the foregoing embodiments, the device information can include at least one of the following: device identification, purpose, and first network access information. The first network access information refers to the network information of the last or previous access of the first device 101, such as the network information of the last interactive communication of the tag in the inventory process. The first network access information can include the network name, network identification, or network index of the last serving site.

[0310] In some embodiments, in the logistics scene such as the inventory process, the device information can also include state information. The state information can be used to indicate whether the current state of the first device 101 is an inbound state or an outbound state.

[0311] In some embodiments, the device information includes a state indication field, and the state indication field is used to indicate that the state of the first device 101 is an inbound state or an outbound state. For example, different values of the field indicate different states.

[0312] Optionally, the status indication field can also be referred to as an inbound / outbound flag field, for indicating whether the first device 101 is in an outbound state, an inbound state, or an unknown state.

[0313] Optionally, the status indication field can occupy 1 or more bits, and different code points or bit values of the field correspond to different states of the first device 101.

[0314] In an example, the status indication field occupies 1 bit, and the 1 bit is of a first value when indicating that the first device 101 is in an inbound state, and the 1 bit is of a second value when indicating that the first device 101 is in an outbound state. Referring to Table 1, the first value can be 0, and the second value can be 1.

[0315] Table 1

[0316] In another example, the field occupies 2 bits, and the 2 bits are of a first value when indicating that the first device 101 is in an inbound state, and the 2 bits are of a second value when indicating that the first device 101 is in an outbound state. In addition, the 2 bits are of other values when the state of the first device 101 can be reserved or unknown. Referring to Table 2, the first value can be 01, the second value can be 10, and the other values can be 00 or 11. In summary, the first device can use one field to indicate its state, such as whether it is in an inbound state or an outbound state.

[0317] Table 2

[0318] In some embodiments, the first device 101 can store a state variable, i.e., set or update or record the value of the state information field, each time the state changes.

[0319] In some embodiments, the first device 101 can store the network information of the last or previous access each time the network changes.

[0320] In some embodiments, the first device 101 can store at least two variables, i.e., the state and the network information of the last or previous access.

[0321] In some embodiments, step S2301 can be omitted, such as the storage operation depends on the device implementation, which can be default or default or adopted by default.

[0322] Step S2302, the network device 102 sends a fourth signaling to the first device 101.

[0323] It should be understood that the network device 102 can send the fourth signaling to one or more first devices. For example, the network device can send the fourth signaling to a specific first device in a targeted manner, or can also send the fourth signaling in a broadcast manner.

[0324] In some embodiments, the fourth signaling is used to indicate the inbound or outbound of the first device 101.

[0325] Optionally, the fourth signaling is used for the inbound or outbound registration scene in the inventory process, and the selected device can be registered or updated.

[0326] In some embodiments, the fourth signaling can be a polling message, or sent in a new signaling.

[0327] Optionally, when the fourth signaling is a polling message, the fourth signaling can be the same as the third signaling described above, and different indications are realized based on different information fields of the signaling. For example, the signaling includes a first field and a second field, the first field is set to a value to indicate that all devices under the network device 102 perform information reporting, and the second field is set to a value to indicate whether to perform inbound or outbound.

[0328] In some embodiments, the fourth signaling includes at least one of the following:

[0329] Inbound indication;

[0330] Outbound indication;

[0331] Second network access information, the second network access information including network information corresponding to the network device.

[0332] Optionally, the inbound indication or the outbound indication can be indicated by one information field, such as the information field occupying 1 bit, the value of the 1 bit being 0 indicating outbound, i.e. identifying outbound registration; the value of the 1 bit being 1 indicating inbound, i.e. identifying inbound registration.

[0333] Optionally, the second network access information corresponds to the network device 102, i.e. corresponds to the current site of the first device 101, or corresponds to the network device that issues the fourth signaling. Wherein, the second network access information can include a current access network site identifier, name or index.

[0334] In some embodiments, the first device 101 receives the fourth signaling and learns the information indicated by the network device 102.

[0335] Step S2303, the first device 101 performs corresponding behavior according to the stored device information and the fourth signaling.

[0336] In some embodiments, the first network access information stored by the first device 101 can be inconsistent or mismatched with the second network access information indicated in the fourth signaling, such as the information being partially different or totally different. Alternatively, the first network access information can be consistent or matched with the second network access information, such as the information being the same. In both scenarios, the first device 101 can have multiple behaviors, which can be determined in combination with the indication of the fourth signaling.

[0337] In some embodiments, the in-storage or out-of-storage indication in the fourth signaling can conflict with the in-storage state or out-of-storage state stored by the first device 101. In view of the capability of the first device 101, the first device 101 can update the state according to the indication of the fourth signaling in this embodiment.

[0338] The behavior of the first device 101 can be seen in the following two implementation manners, or in multiple examples in the two implementation manners:

[0339] In a possible implementation manner, when the fourth signaling includes the in-storage indication, the first device 101 stores the network information corresponding to the network device 102 into the first network access information, and sets the state information field to a first value. The first value can correspond to the fourth signaling, for example, the first value indicates that the state of the first device is the in-storage state.

[0340] In this implementation manner, the first device 101 can update or adjust the device information based on the stored information and the fourth signaling.

[0341] In this implementation manner, when the second network access information is inconsistent with the first network access information, it indicates that the network accessed by the first device 101 changes. The behavior of the first device 101 can be seen in the following first example to second example:

[0342] In the first example, the fourth signaling includes the in-storage indication, but the state stored by the first device 101 is the in-storage state, that is, the value of the state indication field before receiving the fourth signaling is the first value. In this example, the first device 101 can record the state as the in-storage state, or in other words, the first device 101 keeps the state unchanged and records the current network information into the first network access information to indicate that the access is successful. In this example, although the first device 101 has no out-of-storage record, it can still record the state according to the fourth signaling.

[0343] In this example, optionally, the first device 101 can continue to perform the step S2304, that is, report the device information before the current record, so that the network device 102 can determine the state abnormality condition according to the information reported by the first device 101, and thus perform reasonable processing.

[0344] In the second example, the fourth signaling includes an in-coverage indication, and the state stored by the first device 101 is an out-of-coverage state, i.e., the value of the state indication field before the fourth signaling is received is the second value. In this example, the first device 101 can record the state as an in-coverage state, and record the current network information into the first network access information to indicate that the state update is successful. In this example, the first device 101 can be out of coverage of the previous network node and in coverage of the network device 102.

[0345] In this embodiment, when the second network access information is consistent with the first network access information, it indicates that the network accessed by the first device 101 has not changed, and the behavior of the first device 101 can refer to the third example to the fourth example below:

[0346] In the third example, the fourth signaling includes an in-coverage indication, and the state stored by the first device 101 is an in-coverage state, i.e., the value of the state indication field before the fourth signaling is received is the first value.

[0347] In this example, the first device 101 has stored the in-coverage state in the same network, and if the fourth signaling still indicates in-coverage, the fourth signaling can be a repeated instruction, and therefore the first device 101 can ignore the fourth signaling.

[0348] Alternatively, in this example, the first device 101 can record the state as an in-coverage state, or the first device 101 keeps the state unchanged, and record the current network information into the first network access information.

[0349] In the fourth example, the fourth signaling includes an in-coverage indication, and the state stored by the first device 101 is an out-of-coverage state, i.e., the value of the state indication field before the fourth signaling is received is the second value. In this example, the first device 101 that has been out of coverage can be in coverage again, and the first device 101 can record the state as an in-coverage state and record the current network information into the first network access information.

[0350] In this example, optionally, the first device 101 can continue to perform the step S2304, i.e., report the device information before the current record.

[0351] In another possible embodiment, when the fourth signaling includes an out-of-coverage indication, the network device information corresponding to the network device is stored into the first network information, and the state information field is set to the second value, which indicates that the state of the second device is an out-of-coverage state.

[0352] In this embodiment, based on the stored information and the fourth signaling, the first device 101 can update or adjust the device information.

[0353] In the embodiment, when the second network access information is inconsistent with the first network access information, it indicates that the network accessed by the first device 101 changes, and the behavior of the first device 101 can refer to the fifth example to the sixth example below:

[0354] In the fifth example, the fourth signaling includes an out-of-warehouse indication, and the state stored by the first device 101 is an in-warehouse state, that is, the value of the state indication field before the fourth signaling is received is the first value. In this example, the first device 101 can record the state as an out-of-warehouse state, and record the current network information into the first network access information.

[0355] In this example, optionally, the first device 101 can continue to perform step S2304, that is, report the device information before this record.

[0356] In the sixth example, the fourth signaling includes an out-of-warehouse indication, and the state stored by the first device 101 is an out-of-warehouse state, that is, the value of the state indication field before the fourth signaling is received is the second value. In this example, the first device 101 can have been out of the warehouse on the side of the other network, and missed the record of the in-warehouse state under the network device 102. The first device 101 can record the state as an out-of-warehouse state, and record the current network information into the first network access information.

[0357] In this example, optionally, the first device 101 can continue to perform step S2304, that is, report the device information before this record.

[0358] In the embodiment, when the second network access information is consistent with the first network access information, it indicates that the network accessed by the first device 101 does not change, and the behavior of the first device 101 can refer to the seventh example to the eighth example below:

[0359] In the seventh example, the fourth signaling includes an out-of-warehouse indication, and the state stored by the first device 101 is an in-warehouse state, that is, the value of the state indication field before the fourth signaling is received is the first value. In this example, the first device 101 that has been in the warehouse will be out of the warehouse, and the first device 101 can record the state as an out-of-warehouse state, and record the current network information into the first network access information.

[0360] In the eighth example, the fourth signaling includes an out-of-warehouse indication, and the state stored by the first device 101 is an out-of-warehouse state, that is, the value of the state indication field before the fourth signaling is received is the second value. In this example, the first device 101 has been out of the warehouse, and can have missed the in-warehouse indication of the network device 102, or has not changed to the in-warehouse state after being in the warehouse due to insufficient energy and the like. The first device 101 can record the state as an out-of-warehouse state, and record the current network information into the first network access information.

[0361] In the example, the first device 101 can optionally continue to perform step S2304, i.e., report the device information before the current record, so that the network device 102 can determine the state abnormality according to the information reported by the first device 101, and thus perform reasonable processing.

[0362] In some embodiments, after the device information is updated in the above example, the first device 101 can store the updated device information.

[0363] In step S2304, the first device 101 sends the device information of the first device to the network device 102.

[0364] In some embodiments, the implementation of step S2304 can refer to the implementation of step S2104 in the embodiment of FIG. 2a, which will not be described here.

[0365] In some embodiments, the device information reported by the first device 101 to the network device 102 is the device information stored by the first device 101 in step S2301, i.e., the information of the last communication before the communication with the network device 102, such as the last network information and the state in the last inventory process.

[0366] In some embodiments, after step S2303, the first device 101 performs device information updating, such as state updating or last network information updating. The device information reported by the first device 101 can also include the device information after the updating.

[0367] The method related to the embodiments of the present disclosure can include at least one of steps S2301-S2304. For example, the method includes steps S2302-S2304.

[0368] In some embodiments, other optional implementations can be described before or after the description of FIG. 2c.

[0369] In the embodiments of the present disclosure, the position updating of the environment Internet of Things device is realized based on network polling or active exploration. After receiving the fourth signaling of the network device 102, the first device 101 can perform corresponding behaviors based on the stored information and the fourth signaling, and can report the device information. The network device 102 can update the state and position of the first device 101 in time based on the inventory warehouse entry and warehouse exit registration.

[0438] In the embodiments of the present disclosure, the position of the ambient IOT device is updated in time through two ways of ambient IOT device active reporting and network active inventory warehousing and registration. In order to facilitate understanding of the embodiments of the present disclosure, some examples are listed as follows:

[0439] Example one:

[0440] This example is based on ambient IOT reporting (for example, “I am here now!”).

[0441] After the ambient IOT device (hereinafter referred to as tag) is powered on, the ambient IOT network related information is obtained, such as the name, index, network id of the network. For example, it is obtained from the broadcast type command of the system broadcast information type, or from the paging, or from the inventory command Query command.

[0442] Optionally, if the tag finds that the newly acquired network information does not match the network information of the last serving network, the tag actively replies to the network side and reports the tag's own information to the network side.

[0443] Option 1 (Option 1):

[0444] The tag actively accesses the network side, for example, a DO-A type of service, and the tag actively reports its own identification information, and the reporting purpose is at least one of the following.

[0445] Option 2 (Option 2):

[0446] After the tag is powered on, if a paging is received or a stocktaking process such as a Query command is received, whether the tag belongs to the selected tag or not, the tag actively participates in the current stocktaking, and after the tag and the network side handshake, the tag actively reports its own identification information, and the reporting purpose is at least one of the following.

[0447] Optionally, the ambient IOT device corresponds to the first device 101 of the foregoing embodiment, and the network corresponds to the network device 102 of the foregoing embodiment.

[0448] Example two:

[0449] This example is based on network polling reporting (for example, "who is here?").

[0450] Option 1 (Option 1):

[0451] The network side issues a polling message for indicating that all tags need to respond to the network for identification reporting. The polling message can be a new message, for example, a polling message, or a paging message, a target tag indicating "all", or a Query message, a target tag indicating "all". All terminals compete to access the network based on the slot-ALOHA method.

[0452] Option 2 (Option 2) can include the following steps S1-S3:

[0453] Step S1, the ambient IOT device stores two variables, which are:

[0454] (1) Inbound or outbound flag: used to store whether the device is in an outbound state or an inbound state, or an unknown state. For example, refer to Table 2.

[0455] (2) Last serving site id / name / index: indicates the network information of the last time, the most recent time and the tag interacts with the network.

[0456] Step S2, the network issues an inbound / outbound registration instruction or a polling instruction, which contains the following information:

[0457] (1) Inbound / outbound indication: indicates whether the current instruction is an inbound registration or an outbound registration. For example, 0 indicates an outbound registration and 1 indicates an inbound registration.

[0458] (2) Current site id / name / index: the network information of the network that issues the instruction.

[0459] Step S3, the tag behaves as follows according to the information in the instruction and the stored information:

[0460] (1) If the current network information (current site id / name / index) in the instruction and the last serving network information (last serving site id / name / index) stored by the tag do not match:
