Description

Paging method and device supporting passive Internet of Things devices

[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on February 6, 2024, with application number 202410170994.5 and application name “Paging Method and Apparatus Supporting Passive Internet of Things Devices,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and more specifically, to a paging method and apparatus supporting passive Internet of Things devices. Background Art

[0003] The number of IoT devices using cellular network positioning is increasing. However, due to the high power consumption and cost of traditional IoT devices, as well as the high maintenance costs associated with batteries, the introduction of non-battery-based IoT devices can significantly reduce both device costs and maintenance costs, further reducing power consumption and further contributing to a greener IoT network.

[0004] The current paging process for A-IoT devices uses the traditional cellular network paging mechanism for active IoT devices. Active IoT devices autonomously search for paging information based on paging opportunities (POs). However, passive IoT devices cannot autonomously search for paging information based on POs. Therefore, the traditional cellular network response paging mechanism is not applicable to passive IoT devices.

[0005] Therefore, the related technology cannot realize paging for passive IoT devices. Summary of the Invention

[0006] The present disclosure provides a paging method and apparatus supporting passive IoT devices, which solves the problem that related technologies cannot implement paging for passive IoT devices.

[0007] In a first aspect, the present disclosure provides a paging method supporting a passive IoT device, which is applied to a first passive IoT device. The method includes:

[0009] When it is determined that the page is being received, information in the paging message is read and / or the paging message is responded to.

[0010] In the embodiment of the present disclosure, if the first passive IoT device receives a paging message, it determines whether it is being paged based on the paging message. When the first passive IoT device determines that it is being paged (i.e., the first passive IoT device is the passive IoT device being paged, or any passive IoT device in the group of passive IoT devices being paged), it can read all the information in the paging message; and / or respond to the paging message. That is, if the paging message is used to page a passive IoT device or a group of passive IoT devices, the first passive IoT device can reflect back information to indicate that it is the passive IoT device being paged; if the paging message is used to instruct the paged passive IoT device or each passive IoT device in the group of passive IoT devices being paged to perform the operation indicated or requested in the paging message, the first passive IoT device can respond to the operation requested or instructed to be performed in the paging message based on the request command information carried in the paging message or the index corresponding to the request command information, thereby implementing paging for the passive IoT device.

[0011] Therefore, based on the above-mentioned targeted paging design of at least one or at least one group of passive IoT devices, at least one or at least one group of passive IoT devices is triggered to respond in a targeted manner according to the paging message, thereby achieving the purpose of efficiently finding suitable and / or inventorying passive IoT devices.

[0012] In some embodiments, the paging message includes at least one of the following: the ID of the paged passive Internet of Things device, the group ID of the paged group passive Internet of Things device, the group type of the paged group passive Internet of Things device, the group mask of the paged group passive Internet of Things device, the ID list of passive Internet of Things devices in the paged group passive Internet of Things device, and first indication information, where the first indication information is used to indicate that the paging message is point-to-point information or broadcast information; or,

If the comparison is consistent, it is determined that the device is paged;

[0018] If the paging message is a broadcast signal, the group ID or group type corresponding to the broadcast signal is determined based on the correspondence between the broadcast signal and the group ID or group type of the group passive Internet of Things device. If the group ID corresponding to the broadcast signal is consistent with the group ID of the group to which the first passive Internet of Things device belongs, or if the group type corresponding to the broadcast signal is consistent with the group type of the group to which the first passive Internet of Things device belongs, it is determined that the device is being paged.

If the paging message is a point-to-point message and carries the ID of a specified passive IoT device, the first passive IoT device may compare its own ID with the ID of the specified passive IoT device. If the comparison is consistent, it indicates that the first passive IoT device is the passive IoT device being paged; if the paging message is a broadcast message and carries an identifier of the passive IoT device being paged or the group of passive IoT devices being paged (for example, ID, group ID, group type, group ID list, group mask, etc.), the first passive IoT device may compare its own ID or the group ID or group type or group mask of the group to which it belongs with the identifier carried in the paging message. If the comparison is consistent, it indicates that the first passive IoT device is the passive IoT device being paged; if the paging message is a broadcast message and does not It carries an identification of the passive IoT device being paged or the group of passive IoT devices being paged, indicating that all passive IoT devices receiving the paging message are paged, that is, the first passive IoT device is the paged passive IoT device; if the paging message is sent in the form of a broadcast signal, since one broadcast signal corresponds to the group ID or group type of a group of passive IoT devices, the group ID or group type of the paged group of passive IoT devices can be determined based on the broadcast signal, and the first passive IoT device can be compared based on its own group ID with the group ID corresponding to the broadcast signal, or the first passive IoT device can be compared based on its own group type with the group type corresponding to the broadcast signal. If the comparison is consistent, it indicates that the first passive IoT device is the paged passive IoT device.

[0197] The paging message does not carry the second indication information, and the second indication information includes at least: the ID of the paged passive Internet of Things device, the group ID of the paged group passive Internet of Things device, the group type of the paged group passive Internet of Things device, the group mask of the paged group passive Internet of Things device, and the ID list of the passive Internet of Things devices in the paged group passive Internet of Things device.

[0198] In the embodiment of the present disclosure, the paging message may be sent in a point-to-point manner (if the paging message is used to instruct the specified passive IoT device to perform the operation corresponding to the request command information, the paging message may be sent in a point-to-point manner), or it may be sent in a broadcast manner, wherein the broadcast manner includes a broadcast information manner or a broadcast signal manner. If the paging message is a point-to-point message and carries the ID of the specified passive IoT device, the passive IoT device that receives the paging message can compare its own ID with the ID of the specified passive IoT device. If the comparison is consistent, it indicates that the passive IoT device is the paged passive IoT device; if the paging message is a broadcast message and carries an identifier of the paged passive IoT device or the paged group passive IoT device (for example, ID, group ID, group type, group ID list, group mask, etc.), each passive IoT device that receives the paging message can compare its own ID or the group ID or group type or group mask of the group to which it belongs with the identifier carried in the paging message. If the comparison is consistent, it indicates that the passive IoT device is the paged passive IoT device. device; if the paging message is a broadcast message and does not carry the identification of the passive IoT device being paged or the group passive IoT device being paged, it means that all passive IoT devices receiving the paging message are paged; if the paging message is sent in the form of a broadcast signal, since one broadcast signal corresponds to the group ID or group type of a group of passive IoT devices, the group ID or group type of the group passive IoT device being paged can be determined based on the broadcast signal. The passive IoT device that receives the paging message can compare the group ID to which it belongs with the group ID corresponding to the broadcast signal or compare the group type to which it belongs with the group type corresponding to the broadcast signal. If the comparison is consistent, it means that the passive IoT devices that receive the paging message are the passive IoT devices being paged.

[0199] Therefore, based on the above-mentioned paging method for passive IoT devices or groups of passive IoT devices, the methods of sending paging messages to the target node or at least one passive IoT device can be diverse, and the paging messages sent under different paging methods may correspond to the same or different paging purposes, that is, the paging message can be for paging the device, or it can be for counting or inventorying the paged device.

[0200] In some embodiments, the request command information in the paging message includes at least one of the following:

[0201] Providing information including the ID of the passive IoT device being paged;

[0202] Reply request ACK;

[0203] Obtaining information indicated in a memory of the paged passive IoT device;

[0204] Write operation;

[0205] Obtain sensor information of the paged passive IoT device.

[0206] In the disclosed embodiments, if a paging message carries request command information or an index corresponding to the request command information, a passive IoT device that receives the paging message, upon determining that it has been paged, retrieves the request command information in the paging message and responds according to the requirements of the request command information. Thus, by responding to the paging message, an inventory or count of at least one passive IoT device or group of passive IoT devices is achieved.

[0207] In some embodiments, the paging message includes third indication information, and the third indication information is used to instruct each passive Internet of Things device in the paged group of passive Internet of Things devices or all paged passive Internet of Things devices under the first base station to respond in a staggered manner, and the first base station is the target node.

[0208] In some embodiments, the third indication information includes any one of the following: indication information instructing each paged passive Internet of Things device to determine a response time, indication information instructing each paged passive Internet of Things device to use a predefined algorithm to calculate a response time, and indication information instructing each paged passive Internet of Things device to respond with a delay.

[0209] In the embodiment of the present disclosure, in order to ensure that the network can accurately receive the paging response of each paged passive Internet of Things device, each paged passive Internet of Things device can determine its own response time based on the third indication information carried in the paging message, and then respond to the broadcast paging message in a time-sharing manner based on its own response time.

[0210] In some embodiments, the first paging message includes at least one of the following: a group type of the passive IoT device, and the group type includes at least one of the following: a function type, a location type, a process type, and a usage type.

[0211] In the disclosed embodiment, the passive IoT device grouping includes attributes such as group ID, group type or group mask, group type, etc., wherein the group type includes types divided into function class, location class, process class, and purpose class. Therefore, the network can carry the type of passive IoT device grouping through paging messages to search for multiple devices at a time, thereby improving paging or inventory efficiency.

[0212] In some embodiments, the paging message is a radio resource control RRC message, or the paging message is carried by any one of a media access control protocol data unit MAC PDU, a media access control unit MAC CE, and a PDU of a newly defined protocol stack; wherein the PDU includes a data PDU or a control PDU.

[0213] In a tenth aspect, the present disclosure provides a non-transitory readable storage medium, wherein the non-transitory readable storage medium stores a computer program, and the computer program is used to enable a processor to execute any of the methods described above.

[0214] The present disclosure provides a paging method and apparatus supporting passive Internet of Things devices, which first receives a paging message; the paging message is used for at least one of the following: paging a passive Internet of Things device; paging a group of passive Internet of Things devices; instructing the paged passive Internet of Things device to perform a corresponding operation according to the request command information carried by the paging message or the index corresponding to the request command information; instructing each passive Internet of Things device in the paged group of passive Internet of Things devices to perform a corresponding operation according to the request command information carried by the paging message or the index corresponding to the request command information; when determining to be paged, reading the information in the paging message and / or responding to the paging message. Therefore, based on the above-mentioned targeted paging design of at least one or at least one group of passive Internet of Things devices, at least one or at least one group of passive Internet of Things devices is triggered to respond in a targeted manner according to the paging message, thereby achieving the purpose of efficiently finding suitable and / or inventorying passive Internet of Things devices.

[0230] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0231] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0232] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0233] In order to clearly understand the technical solutions of the present disclosure, the solutions of related technologies are first introduced in detail.

[0234] The current paging process for IoT devices follows the traditional cellular network paging mechanism for active IoT devices. Active IoT devices autonomously search for paging information based on paging opportunities (POs). However, passive IoT devices cannot autonomously search for paging information based on POs. Therefore, the traditional cellular network's response paging mechanism is not suitable for passive IoT devices. The terminal device no longer needs to autonomously search for paging information based on POs, requiring the design of new mechanisms and processes to support passive IoT devices. Consequently, related technologies cannot implement paging for passive IoT devices.

[0235] Therefore, based on the above research, the paging method and apparatus for supporting passive IoT devices proposed in the present disclosure are proposed. In the present disclosure, when a passive IoT device is determined to be a paged passive IoT device, or any passive IoT device in a group of paged passive IoT devices, based on the indication in the received paging message, it reads the information in the paging message and / or responds to the paging message. Therefore, based on the above-mentioned targeted paging design of at least one passive IoT device or at least one group of passive IoT devices, at least one passive IoT device or at least one group of passive IoT devices is triggered to respond in a targeted manner according to the paging message, thereby achieving the purpose of efficiently finding suitable passive IoT devices and improving the efficiency of inventorying passive IoT devices.

[0236] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0237] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0238] Referring to Figure 1, Figure 1 is a flow chart of a paging method for supporting passive IoT devices provided in an embodiment of the present disclosure. The paging method for supporting passive IoT devices provided in this embodiment is performed by a first passive IoT device (e.g., a device or product including a barcode tag, a wristband tag, a hangtag, etc., which are not specifically limited herein), and the paging method for supporting passive IoT devices is described in detail.

[0239] The paging method supporting passive IoT devices provided by the embodiment of the present disclosure includes the following steps:

[0240] Step 101: Receive a paging message.

[0241] Among them, the paging message is used for at least one of the following: paging a passive Internet of Things device; paging a group of passive Internet of Things devices; instructing the paged passive Internet of Things device to perform a corresponding operation according to the request command information carried by the paging message or the index corresponding to the request command information; instructing each passive Internet of Things device in the paged group of passive Internet of Things devices to perform a corresponding operation according to the request command information carried by the paging message or the index corresponding to the request command information.

[0242] Specifically, the paging message here can be sent by a target node (a base station, a terminal, or other auxiliary nodes other than the base station or the terminal (for example, a relay device, an integrated access backhaul (IAB) device, etc.), etc., and the following takes a base station (for example, the next generation base station (gNodeB or gNB)) as an example), or it can be sent by a core network device. Specifically, if the paging message is used to page a passive IoT device or a group of passive IoT devices, the base station can broadcast the paging message, or the base station can send the paging message to a specified passive IoT device in a point-to-point manner; if the paging message is used to instruct the paged passive IoT device to perform a corresponding operation according to the request command information carried by the paging message or the index corresponding to the request command information, or to instruct each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation according to the request command information carried by the paging message or the index corresponding to the request command information, the paging message can be sent by the base station or the core network device.

[0243] Step 102: When it is determined that the device is being paged, read the information in the paging message and / or respond to the paging message.

[0244] If any passive IoT device (herein, the first passive IoT device) receives a paging message, it determines whether it is being paged based on the paging message. When the first passive IoT device determines that it is being paged (i.e., the first passive IoT device is the paged passive IoT device, or any passive IoT device in the paged group of passive IoT devices), it can read all the information in the paging message; and / or respond to the paging message. That is, if the paging message is used to page a passive IoT device or a group of passive IoT devices, the first passive IoT device can reflect back information to indicate that it is the paged passive IoT device; if the paging message is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform the operation indicated or requested in the paging message, the first passive IoT device can respond to the operation requested or instructed to be performed in the paging message based on the request command information carried in the paging message or the index corresponding to the request command information, thereby supporting paging of passive IoT devices, i.e., implementing paging for passive IoT devices.

[0245] In the embodiments of the present disclosure, based on the above-mentioned targeted paging design of at least one or at least one group of passive IoT devices, at least one or at least one group of passive IoT devices is triggered to respond in a targeted manner according to the paging message, thereby achieving the purpose of efficiently finding suitable and / or inventorying passive IoT devices.

[0246] Optionally, the receiving a paging message includes:

[0247] receiving the paging message sent by a target node, where the target node includes any one of the following: a base station, a terminal, or an auxiliary node; or

[0248] Receive a first paging message sent by a core network device, where the first paging message is used to instruct the paged passive Internet of Things device or the paged passive Internet of Things device or each passive Internet of Things device to perform a corresponding operation according to the request command information carried by the paging message or the index corresponding to the request command information.

[0249] In the embodiment of the present disclosure, the paging message can be sent by the target node, and the paging message can be used to paging devices (here referring to passive IoT devices or group passive IoT devices), and can also be used to instruct the paged device to perform corresponding operations based on the request or instruction in the paging message. It can also be used to paging devices and also instruct the paged device to perform corresponding operations based on the request or instruction in the paging message; the paging message can also be sent by the core network device based on the information of the paged device after the paging is fed back to the device through the target node, and the paging message is used to instruct the paged device to perform corresponding operations based on the request or instruction in the paging message. Therefore, the mode of receiving the paging message can be diverse, and the paging messages received under different paging modes may correspond to the same or different paging purposes, that is, the paging message can be for paging devices, or for counting or inventorying the paged devices.

[0250] Specifically, the paging process can be implemented in the following ways:

[0251] Mode 1: As shown in FIG2 , FIG2 is an interactive diagram 1 of a paging method supporting passive IoT devices provided by an embodiment of the present disclosure; the specific process is as follows:

[0252] Step 0. The core network device sends a paging message 1 to the target node. The paging message 1 is used to page the passive IoT device (e.g., to find the target tag).

[0253] Step 1. The target node sends a paging message 2 to the passive IoT device, where the paging message 2 is used to find the target tag.

[0254] Step 2. The paged passive IoT device reflects information 1 back to the target node;

[0255] Step 3. The target node reflects information 2 back to the core network device.

[0256] The information carried by paging message 1 and paging message 2 may be the same or different, and the information contained in reflected back information 1 and reflected back information 2 may be the same or different, which is not specifically limited here. Similar situations in the following embodiments will not be repeated.

[0258] Step 0. The core network device sends a paging message 1 to the target node. The paging message 1 is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation according to the request command information or the index corresponding to the request command information carried in the paging message. The paging message 1 carries a command request (or request command information or the index corresponding to the request command information).

[0259] Step 1. The target node sends a paging message 2 to the passive IoT device. The paging message 2 is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation according to the request command information or the index corresponding to the request command information carried in the paging message. The paging message 2 carries a command request (or the request command information or the index corresponding to the request command information).

[0260] Step 2. The paged passive IoT device feeds back a response 1 to the target node;

[0261] Step 3. The target node feeds back a response 2 to the core network device.

[0262] The information contained in the feedback response 1 and the feedback response 2 may be the same or different, which is not specifically limited here. Similar situations in the following embodiments will not be repeated.

[0263] Mode 3: As shown in FIG4 , FIG4 is a third interactive diagram of a paging method supporting passive IoT devices provided by an embodiment of the present disclosure; the specific process is as follows:

[0264] Step 0. The core network device sends a paging message 1 to the target node. The paging message 1 is used to page the passive IoT device or the paged group of passive IoT devices, and instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation according to the request command information or the index corresponding to the request command information carried by the paging message. The paging message 1 carries a command request (or request command information or the index corresponding to the request command information); that is, the core network device sends a search target tag + command request to the target node;

[0265] Step 1. The target node sends a paging message 2 to the passive IoT device. The paging message 2 is used to page the passive IoT device or a group of passive IoT devices being paged, and instruct the paged passive IoT device or each passive IoT device in the group of passive IoT devices to perform a corresponding operation according to the request command information or the index corresponding to the request command information carried in the paging message. The paging message 2 carries a command request (or request command information or the index corresponding to the request command information). That is, the core network device sends a search target tag + command request to the target node.

[0266] Step 2. The paged passive IoT device feeds back a response 1 to the target node;

[0267] Step 3. The target node feeds back a response 2 to the core network device.

[0268] Mode 4: As shown in FIG5 , FIG5 is a fourth interactive diagram of a paging method supporting passive IoT devices provided by an embodiment of the present disclosure; the specific process is as follows:

[0269] Step 0. The core network device sends a paging message 1 to the paged passive IoT device. The paging message 1 is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation according to the request command information or the index corresponding to the request command information carried by the paging message. The paging message 1 carries a command request (or the request command information or the index corresponding to the request command information). That is, the core network device sends a command request to the paged passive IoT device.

[0270] Step 1. The paged passive IoT device feeds back a response to the core network device.

[0271] Mode 5 (Mode 1 + Mode 2): In conjunction with FIG6 , FIG6 is a fifth interactive diagram of a paging method supporting passive IoT devices provided by an embodiment of the present disclosure; the specific process is as follows:

[0272] Step 0. The core network device sends a paging message 1 to the target node. The paging message 1 is used to page the passive IoT device (e.g., to find the target tag).

[0273] Step 1. The target node sends a paging message 2 to the passive IoT device, where the paging message 2 is used to find the target tag.

[0274] Step 2. The paged passive IoT device reflects information 1 back to the target node;

[0275] Step 3. The target node reflects information 2 back to the core network device.

[0276] Step 4. The core network device sends a paging message 3 to the target node. The paging message 3 is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation according to the request command information or the index corresponding to the request command information carried in the paging message. The paging message 3 carries the command request (or the request command information or the index corresponding to the request command information).

[0277] Step 5. The target node sends a paging message 4 to the passive IoT device. The paging message 4 is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation according to the request command information or the index corresponding to the request command information carried in the paging message. The paging message 4 carries the command request (or the request command information or the index corresponding to the request command information).

[0278] Step 6. The paged passive IoT device feeds back a response 1 to the target node;

[0279] Step 7: The target node feeds back a response 2 to the core network device.

[0280] Mode 6 (Mode 1 + Mode 4): In conjunction with FIG. 7 , FIG. 7 is a sixth interactive diagram of a paging method supporting passive IoT devices provided by an embodiment of the present disclosure; the specific process is as follows:

[0281] Step 0. The core network device sends a paging message 1 to the target node. The paging message 1 is used to page the passive IoT device (e.g., to find the target tag).

[0282] Step 1. The target node sends a paging message 2 to the passive IoT device, where the paging message 2 is used to find the target tag.

[0283] Step 2. The paged passive IoT device reflects information 1 back to the target node;

[0284] Step 3. The target node reflects information 2 back to the core network device.

[0285] Step 4. The core network device sends a paging message 3 to the paged passive IoT device. The paging message 3 is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation according to the request command information or the index corresponding to the request command information carried in the paging message. The paging message 3 carries a command request (or the request command information or the index corresponding to the request command information). That is, the core network device sends a command request to the paged passive IoT device.

[0286] Step 5. The paged passive IoT device feeds back a response to the core network device.

[0287] Optionally, the paging message includes at least one of the following: the ID of the paged passive IoT device, the group ID of the paged group passive IoT device, the group type of the paged group passive IoT device, the group mask of the paged group passive IoT device, the ID list of passive IoT devices in the paged group passive IoT device, and first indication information, where the first indication information is used to indicate that the paging message is point-to-point information or broadcast information; or,

[0288] The paging message is a broadcast signal, and the broadcast signal corresponds to the group ID or group type of the passive IoT device; or

[0289] The paging message does not carry the second indication information, and the second indication information includes at least: the ID of the paged passive Internet of Things device, the group ID of the paged group passive Internet of Things device, the group type of the paged group passive Internet of Things device, the group mask of the paged group passive Internet of Things device, and the ID list of the passive Internet of Things devices in the paged group passive Internet of Things device.

[0290] In the embodiment of the present disclosure, the paging for the passive IoT device may be: group paging of a specified group of passive IoT devices; or paging of no specified passive IoT device; or paging of a specified passive IoT device.

[0291] Optionally, the method further includes:

[0292] If the paging message is a broadcast message and the paging message does not carry the second indication information, determining that the user is being paged;

[0293] If the paging message includes at least one of the following: the ID of the paged passive IoT device, the group ID of the paged group passive IoT device, the group type of the paged group passive IoT device, the group mask of the paged group passive IoT device, and the ID list of passive IoT devices in the paged group passive IoT device, the paging message is compared with the ID of the first passive IoT device or the group ID or group type of the group to which the first passive IoT device belongs or the group mask corresponding to the group to which the first passive IoT device belongs. If the comparison is consistent, it is determined that the device is paged;

[0294] If the paging message is a broadcast signal, the group ID or group type corresponding to the broadcast signal is determined based on the correspondence between the broadcast signal and the group ID or group type of the group passive Internet of Things device. If the group ID corresponding to the broadcast signal is consistent with the group ID and group type of the group to which the first passive Internet of Things device belongs, or if the group type corresponding to the broadcast signal is consistent with the group type of the group to which the first passive Internet of Things device belongs, it is determined that the device is being paged.

[0295] In the embodiment of the present disclosure, the paging message may be sent in a point-to-point manner (if the paging message is used to instruct a specified passive IoT device to perform an operation corresponding to the request command information, the paging message may be sent in a point-to-point manner), or it may be sent in a broadcast manner, wherein the broadcast manner includes a broadcast information manner or a broadcast signal manner. If the paging message is a point-to-point message and carries the ID of a specified passive IoT device, the first passive IoT device may compare its own ID with the ID of the specified passive IoT device. If the comparison is consistent, it indicates that the first passive IoT device is the passive IoT device being paged; if the paging message is a broadcast message and carries an identifier of the passive IoT device being paged or the group of passive IoT devices being paged (for example, ID, group ID, group type, group ID list, group mask, etc.), the first passive IoT device may compare its own ID or the group ID or group type or group mask of the group to which it belongs with the identifier carried in the paging message. If the comparison is consistent, it indicates that the first passive IoT device is the passive IoT device being paged; if the paging message is a broadcast message and does not It carries an identification of the passive IoT device being paged or the group of passive IoT devices being paged, indicating that all passive IoT devices receiving the paging message are paged, that is, the first passive IoT device is the paged passive IoT device; if the paging message is sent in the form of a broadcast signal, since one broadcast signal corresponds to the group ID or group type of a group of passive IoT devices, the group ID or group type of the paged group of passive IoT devices can be determined based on the broadcast signal, and the first passive IoT device can be compared based on its own group ID with the group ID corresponding to the broadcast signal, or the first passive IoT device can be compared based on its own group type with the group type corresponding to the broadcast signal. If the comparison is consistent, it indicates that the first passive IoT device is the paged passive IoT device.

[0296] When inventorying (or counting) certain devices or categories of devices is needed through this paging method, the network can send a broadcast message or signal to search for multiple devices at once, improving inventory efficiency. Therefore, paging can be efficiently implemented for passive IoT devices or groups of passive IoT devices.

[0297] Optionally, the request command information includes at least one of the following:

[0298] Providing information including the ID of the first passive IoT device;

[0299] Reply request (Acknowledgement, ACK);

[0300] Obtaining information indicated in a memory of the first passive IoT device;

[0301] Write operation;

[0302] Obtain sensor information of the first passive IoT device.

[0303] Optionally, the responding to the paging message includes:

[0304] According to the request command information, perform the following corresponding operations:

[0305] Sending information about the ID of the first passive IoT device;

[0306] Send reply ACK information;

[0307] Sending the information indicated in the memory of the first passive Internet of Things device obtained;

[0308] Write the indicated information;

[0309] Send the acquired sensor information of the first passive Internet of Things device.

[0310] In the disclosed embodiment, if a paging message carries request command information or an index corresponding to the request command information, upon determining that the first passive IoT device has been paged, it retrieves the request command information in the paging message and responds according to the requirements in the request command information. Thus, by responding to the paging message, an inventory or count of at least one passive IoT device or group of passive IoT devices is achieved.

[0311] Optionally, the paging message includes third indication information, where the third indication information is used to instruct each passive Internet of Things device in the paged group of passive Internet of Things devices or all paged passive Internet of Things devices under the first base station to stagger their responses, where the first base station is a base station within the first area or that meets the first condition; the responding to the paging message includes:

[0312] determining a response time according to the third indication information;

[0313] Respond to the paging message according to the response time.

[0314] Optionally, the third indication information includes any one of the following: indication information instructing each paged passive Internet of Things device to determine the response time, indication information instructing each paged passive Internet of Things device to calculate a predefined algorithm for the response time, and indication information instructing each paged passive Internet of Things device to respond with a delay.

[0315] In the embodiment of the present disclosure, in order to ensure that the network can accurately receive the paging response of each paged passive Internet of Things device, each paged passive Internet of Things device can determine its own response time based on the third indication information carried in the paging message, and then respond to the broadcast paging message in a time-sharing manner based on its own response time.

[0316] Optionally, the paging message includes at least one of the following: a group type of the passive IoT device, and the group type includes at least one of the following: function class, location class, process class, and purpose class.

[0317] In the embodiment of the present disclosure, the passive IoT device grouping includes attributes such as group ID or group mask, group type, etc., wherein the group type includes types divided into function class, location class, process class, purpose class, etc.

[0318] The network can group numerous passive IoT devices into multiple groups based on one or a combination of the following: function, location, process, and purpose. When an inventory of a particular device type is needed, the network can send broadcast messages to locate multiple devices at once, rather than interacting with each device individually on a point-to-point basis, improving inventory efficiency. Specifically, the network can broadcast a group ID or mask, or establish a communication connection with a group of devices by sending different signals (referred to in this case, broadcast signals) representing different groups (i.e., corresponding to different group IDs and group types), improving inventory efficiency.

[0319] Therefore, the network (here refers to the base station or core network equipment) can carry the type of grouping of passive IoT devices through paging messages to search for multiple devices at a time, thereby improving paging or inventory efficiency.

[0320] Optionally, the paging message is a Radio Resource Control (RRC) message; or,

[0321] The paging message is carried by any one of a Medium Access Control Protocol Data Unit (MAC PDU), a Medium Access Control-Control Element (MAC CE), and a newly defined protocol stack (Protocol Data Unit, PDU); wherein the PDU includes a data PDU or a control PDU.

[0322] Taking the target node as a base station as an example, the following describes in detail a paging method supporting passive IoT devices through specific embodiments.

[0323] For the base station side process:

[0324] 1. Send a paging message, optionally with a command request;

[0325] 2. After receiving ACK, optional command request is sent;

[0326] For the device side process:

[0327] 1. The device receives the paging information and obtains the command requirements;

[0328] 2. Provide feedback as required;

[0329] Example 1 (Specify a group of passive IoT devices (e.g., a group of devices) for group paging, and the base station sends broadcast information)

[0330] Prerequisite: The network must know the IDs of a group of devices, or the group ID and group type in advance. For example, if a command needs to be written for a specific group of devices, the network must search for a specific device (here, passive IoT devices) or inventory a specific group or type of devices.

[0331] The attributes of grouping include: group ID, group type; group type: function class, location class, process class, purpose class and other classification types.

[0332] 1) The core network is triggered and requested to write certain information to the group of devices or to inventory the group of devices;

[0333] a. The group can be expressed in the form of group ID and group type, which are previously assigned by the system;

[0334] b. If there is no group ID, but an ID list of the group of devices (i.e., an ID list): the notified base station uses this ID list to page each device. The specific paging process is the same as the above-mentioned base station side and device side processes and will not be repeated here.

[0335] 2) The core network sends group information (eg, attributes contained in the group) and sends the group information and corresponding command information (here, request command information) to the designated base station.

[0336] 3) Optionally, the command message (here, the request command message) contains one or a combination of the following command messages: requesting a reply ack; requesting to obtain specified information in the device memory (specifying the information specified in the corresponding command message); requesting a device write operation; obtaining sensor information (i.e., sensor information, such as the temperature of an ID card, etc.).

[0337] 4) The base station sends a broadcast message containing the group ID or group mask and a request command, requiring the device to respond.

[0338] 5) The device receives the paging message and compares the group ID carried in the message sent by the base station with its own group ID. If they match, it reads the information in the paging message or responds to the paging message. This group ID can be configured by the core network (optionally, it can be configured through other means and notified to the network). The device responds to the request by replying to the base station message; obtaining specified information from the device memory; performing a device write operation; or obtaining sensor information.

[0339] Example 2 (Specify a group of passive IoT devices (e.g., a group of devices) for group paging, and the base station sends a broadcast signal)

[0340] Prerequisite: The network must know a group of device IDs or group IDs in advance. For example, if you need to write a command for a specific group of devices, you need to find a specific device or inventory a specific group or type of devices.

[0341] The attributes of the group include: group ID, group type: function class, location class, process class, purpose class and other classification types.

[0342] Steps 1)-3) are the same as steps 1)-3) in Example 1 and will not be repeated here.

[0343] 4) The base station sends different broadcast signals to represent different groups. The group IDs represented by different broadcast signals can be pre-set in the protocol. The base station also carries the request command information.

[0344] 5) The device receives a paging message. If the group ID represented by the broadcast signal matches its own group ID, it reads the information in the paging message or responds to the paging message. The device responds to the request by replying to the base station message; obtaining specified information from the device memory; performing a write operation on the device; or obtaining sensor information.

[0345] Example 3 (paging of unspecified passive IoT devices, with mod indication information carried in the paging message)

[0346] Precondition: The network broadcasts notifications to all subordinate devices to perform certain services or actions [Device-Terminated (DT), Downlink-Triggered Uplink Session (DO-DTT) service types]

[0348] 2) The core network sends information to the base station in the corresponding area or the base station that meets the conditions according to the specified area, and specifies the corresponding command information.

[0349] 3) Optionally, the paging message contains one of the following command information or a combination thereof: requesting an ACK reply; or requesting to obtain specified information in the device memory; or a write operation; or obtaining sensor information.

[0350] 4) The paging message does not specify a device ID, indicating that all terminals (devices) are required to respond.

[0351] 5) Optionally, in order to stagger the responses of the devices, the paging message carries mod indication information (i.e., indication information that instructs each paged passive IoT device to determine the response time. Specifically, the device identification ID is indicated by a modulo operation with a number specified by the network, and the remainder obtained is used as the device response time. The modulo operation is to find the remainder when two numbers are divided. Here, the indication is the specification of the modulo operation). After processing according to its own ID number and mod information (such as a specific value), the device responds to the broadcast paging message in a time-sharing manner (based on the scheduling of the base station).

[0352] Example 4 (paging of passive IoT devices is not specified, and the paging message carries staggered response indication information, such as instructing the device which algorithm to use for processing)

[0353] Precondition: Network broadcast notification to all subordinate devices to perform a certain type of service or behavior [DT, DO-DTT service type]

[0354] 1) The core network is triggered, and all device IDs and their corresponding information within the specified area or specified conditions are counted;

[0355] 2) The core network sends information to the base station in the corresponding area or the base station that meets the conditions according to the specified area, and specifies the corresponding command information.

[0356] 3) Optionally, the paging message contains one or a combination of the following command information: requesting an ACK reply; or requesting to obtain specified information in the device memory; or a write operation; or obtaining sensor information.

[0357] 4) The paging message does not specify a Device ID, indicating that all terminals are required to respond.

[0358] 5) Optionally, in order to stagger the responses of the devices, the paging information carries staggered response indication information, instructing the device which algorithm to use for processing.

[0359] 6) After processing according to its own ID number and the indicated algorithm, the device responds to the broadcast paging message in a time-sharing manner (based on the scheduling of the base station).

[0360] Example 5 (paging of unspecified passive IoT devices, with the paging message carrying staggered response instructions, for example, instructing the device to select an algorithm predefined in the protocol based on its own ID and stagger responses in different time periods)

[0361] Precondition: Network broadcast notification to all subordinate devices to perform a certain type of service or behavior [DT, DO-DTT service type]

[0362] 1) The core network is triggered, and all device IDs and their corresponding information within the specified area or specified conditions are counted;

[0363] 2) The core network sends information to the base station in the corresponding area or the base station that meets the conditions according to the specified area, and specifies the corresponding command information.

[0364] 3) Optionally, the paging message contains one or a combination of the following command information: requesting to provide own ID information; or requesting to obtain specified information in the device memory; or a write operation; or obtaining sensor information.

[0365] 4) The paging message does not specify a Device ID, indicating that all terminals are required to respond.

[0368] 7) If further information (eg, other information) is requested in step 3), the device responds with the requested content in step 3).

[0369] Example 6 (Specifying the Paging of a Device)

[0370] The network knows the ID of a device in advance. When it needs to write a command for this device or count the number of devices, it searches for the device. [DT service type]

[0371] 1) The core network is triggered and requested to write certain information or obtain information about the device;

[0372] 2) The core network sends the Device ID to the specified base station and sends the specified corresponding command information.

[0373] 3) The notified base station uses this ID to send information to find the device: optionally, including the cell ID and the device ID;

[0374] 4) Optionally, the paging message contains one of the following command information or a combination thereof: requesting an ACK reply; or requesting to obtain specified information in the device memory; or requesting a write operation; or requesting to obtain sensor information.

[0375] 5) The device responds to the base station's message with an ACK; retrieves specified information from the device's memory; performs a write operation; or retrieves sensor information.

[0376] 6) The device receives the paging message and compares the ID carried in the message sent by the base station with its own ID. If they match, it reads the information in the paging message or responds to the paging message. The ID is the communication identification ID configured by the core network.

[0377] The definition of paging message is:

[0378] The specific paging message data format may be an RRC message, or a MAC PDU or MAC CE, or a PDU of a newly defined protocol stack; optionally, it may include a data PDU or a control PDU, and specifically include one or a combination of the following information:

[0379] 1. Indicates whether the message is point-to-point or broadcast;

[0380] 2. Specify the Device ID information;

[0385] 7. Instruct the devices in the group to stagger their response indication information, such as mod value; or a specific algorithm; or response delay indication.

[0386] Therefore, the paging method for supporting passive IoT devices proposed in the present disclosure is a method for paging passive IoT devices in a cellular network, which can achieve the positioning of such passive IoT devices. This method is different from the paging method of traditional cellular networks and abandons the traditional mechanism of terminals periodically searching for paging messages. It is also different from the inefficient method of radio frequency identification (RFID) devices searching for devices one by one. Through the design of targeted group paging messages, at least one group of terminals is triggered to respond in a targeted manner according to the paging information, thereby achieving the purpose of efficiently finding the right terminal.

[0387] It should be noted here that the paging method for supporting passive IoT devices provided by the present disclosure with the first passive IoT device as the execution subject can be specifically implemented with reference to the embodiments shown in Figures 1 to 7, and the specific implementation process will not be repeated here.

[0388] Referring to FIG8 , FIG8 is a flow chart of a paging method for supporting passive IoT devices according to another embodiment of the present disclosure, which is applied to a target node, wherein the target node includes any one of the following: a base station, a terminal, or an auxiliary node; the method includes:

[0389] Step 801: Determine a paging message; the paging message is used for at least one of the following: paging a passive IoT device; paging a group of passive IoT devices; instructing the paged passive IoT device to perform a corresponding operation based on the request command information or the index corresponding to the request command information carried in the paging message; instructing each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation based on the request command information or the index corresponding to the request command information carried in the paging message;

[0390] Step 802: Send the paging message.

[0391] In the embodiment of the present disclosure, the target node determines a paging message and sends the paging message in a point-to-point manner or a broadcast manner. If the paging message is used to page a passive IoT device or a group of passive IoT devices, the paged device (one passive IoT device or a group of passive IoT devices or all passive IoT devices) can reflect back information to indicate that it is the passive IoT device being paged; if the paging message is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform the operation indicated or requested in the paging message, the paged device can respond to the request or instruction in the paging message according to the request command information carried in the paging message or the index corresponding to the request command information, thereby implementing paging for the passive IoT device.

[0392] Therefore, based on the above-mentioned targeted paging design of at least one or at least one group of passive IoT devices, at least one or at least one group of passive IoT devices is triggered to respond in a targeted manner according to the paging message, thereby achieving the purpose of efficiently finding suitable and / or inventorying passive IoT devices.

[0393] Optionally, the paging message includes at least one of the following: the ID of the paged passive IoT device, the group type of the paged group passive IoT device, the group ID of the paged group passive IoT device, the group mask of the paged group passive IoT device, the ID list of passive IoT devices in the paged group passive IoT device, and first indication information, where the first indication information is used to indicate that the paging message is point-to-point information or broadcast information; or,

[0394] The paging message is a broadcast signal, and there is a corresponding relationship between the broadcast signal and the group ID or group type of the group passive IoT device;

[0395] Alternatively, the paging message does not carry the second indication information, and the second indication information includes at least: the ID of the passive Internet of Things device being paged, the group ID of the group passive Internet of Things device being paged, the group type of the group passive Internet of Things device being paged, the group mask of the group passive Internet of Things device being paged, and the ID list of the passive Internet of Things devices in the group passive Internet of Things device being paged.

[0396] In the embodiment of the present disclosure, the paging message may be sent in a point-to-point manner (if the paging message is used to instruct the specified passive IoT device to perform the operation corresponding to the request command information, the paging message may be sent in a point-to-point manner), or it may be sent in a broadcast manner, wherein the broadcast manner includes a broadcast information manner or a broadcast signal manner. If the paging message is a point-to-point message and carries the ID of the specified passive IoT device, the passive IoT device that receives the paging message can compare its own ID with the ID of the specified passive IoT device. If the comparison is consistent, it indicates that the passive IoT device is the passive IoT device being paged; if the paging message is a broadcast message and carries an identifier of the passive IoT device being paged or the group of passive IoT devices being paged (for example, ID, group ID, group type, group ID list, group mask, etc.), each passive IoT device that receives the paging message can compare its own ID or the group ID or group type or group mask of the group to which it belongs with the identifier carried in the paging message. If the comparison is consistent, it indicates that the passive IoT device is the passive IoT device being paged. Networked device; if the paging message is a broadcast message and does not carry the identification of the passive IoT device being paged or the group of passive IoT devices being paged, it means that all passive IoT devices receiving the paging message are paged; if the paging message is sent in the form of a broadcast signal, since one broadcast signal corresponds to the group ID or group type of a group of passive IoT devices, the group ID or group type of the group of passive IoT devices being paged can be determined based on the broadcast signal. The passive IoT device that receives the paging message can compare the group ID to which it belongs with the group ID corresponding to the broadcast signal or the group type to which it belongs with the group type corresponding to the broadcast signal. If the comparison is consistent, it means that the passive IoT devices that receive the paging message are the passive IoT devices being paged.

[0397] Therefore, based on the above-mentioned paging method for passive IoT devices or groups of passive IoT devices, the methods of sending paging messages can be diverse, and the paging messages sent under different paging methods may correspond to the same or different paging purposes, that is, the paging message can be for paging the device, or it can be for counting or inventorying the paged devices.

[0398] Optionally, the request command information includes at least one of the following:

[0399] Providing information including the ID of the passive IoT device being paged;

[0400] Reply request ACK;

[0401] Obtaining information indicated in a memory of the paged passive IoT device;

[0402] Write operation;

[0403] Obtain sensor information of the paged passive IoT device.

[0404] In the disclosed embodiments, if a paging message carries request command information or an index corresponding to the request command information, a passive IoT device that receives the paging message, upon determining that it has been paged, retrieves the request command information in the paging message and responds according to the requirements of the request command information. Thus, by responding to the paging message, an inventory or count of at least one passive IoT device or group of passive IoT devices is achieved.

[0405] When inventorying (or counting) certain devices or categories of devices is needed through this paging method, the network can send a broadcast message or signal to search for multiple devices at once, improving inventory efficiency. Therefore, paging can be efficiently implemented for passive IoT devices or groups of passive IoT devices.

[0406] Optionally, the paging message includes third indication information, and the third indication information is used to instruct each passive Internet of Things device in the paged group of passive Internet of Things devices or all paged passive Internet of Things devices under the first base station to respond in a staggered manner. The first base station is a base station within the first area or meets the first condition, and the base station is the target node.

[0407] Optionally, the third indication information includes any one of the following: indication information instructing each paged passive Internet of Things device to determine the response time, indication information instructing each paged passive Internet of Things device to calculate a predefined algorithm for the response time, and indication information instructing each paged passive Internet of Things device to respond with a delay.

[0408] In the embodiment of the present disclosure, in order to ensure that the network can accurately receive the paging response of each paged passive Internet of Things device, each paged passive Internet of Things device can determine its own response time based on the third indication information carried in the paging message, and then respond to the broadcast paging message in a time-sharing manner based on its own response time.

[0409] Optionally, the paging message includes at least one of the following: a group type of the passive IoT device, and the group type includes at least one of the following: function class, location class, process class, and purpose class.

[0410] In the disclosed embodiment, the passive IoT device grouping includes attributes such as group ID or group mask, group type, etc., wherein the group type includes types divided into function class, location class, process class, and purpose class. Therefore, the network can carry the type of passive IoT device grouping through paging messages to search for multiple devices at a time, thereby improving paging or inventory efficiency.

[0411] Optionally, the paging message is a radio resource control RRC message, or the paging message is carried by any one of a media access control protocol data unit MAC PDU, a media access control unit MAC CE, and a PDU of a newly defined protocol stack; wherein the PDU includes a data PDU or a control PDU.

[0412] Optionally, the determining the paging message includes:

[0413] Receive the paging message sent by the core network device.

[0414] In the embodiment of the present disclosure, the paging message can be sent by the core network device, and the paging message can be used to paging devices (here referring to passive IoT devices or group passive IoT devices), and can also be used to instruct the paged device to perform corresponding operations based on the request or instruction in the paging message. It can also be used for both paging devices and instructing the paged device to perform corresponding operations based on the request or instruction in the paging message. Among them, if the paging message is used to instruct the paged device to perform corresponding operations based on the request or instruction in the paging message, then the paging message can be sent by the core network device based on the information of the paged device after the paging is fed back to the device through the target node. Therefore, based on the above-mentioned paging method, the paged devices can be efficiently counted or inventoried.

[0415] Optionally, the sending the paging message includes:

[0416] Sending the paging message via broadcasting;

[0417] The broadcasting method includes a method of broadcasting information or a method of broadcasting signals.

[0418] In the disclosed embodiments, paging messages may be sent in a point-to-point manner (if the paging message is used to instruct a specified passive IoT device to perform an operation corresponding to the requested command information, the paging message may be sent in a point-to-point manner) or in a broadcast manner, where the broadcast manner includes broadcasting information or broadcasting a signal. This allows for diversified paging of passive IoT devices and improves paging or inventory efficiency.

[0419] It should be noted that the paging method for supporting passive IoT devices with the target node as the execution subject provided by the present disclosure can be specifically implemented with reference to the embodiments shown in Figures 2 to 8, and the specific implementation process will not be repeated here.

[0420] 9 , which is a flow chart of a method for supporting paging of passive IoT devices according to another embodiment of the present disclosure, and applied to a core network device, the method includes:

[0421] Step 901: Determine a paging message; the paging message is used for at least one of the following: paging a passive IoT device; paging a group of passive IoT devices; instructing the paged passive IoT device to perform a corresponding operation based on the request command information or the index corresponding to the request command information carried in the paging message; instructing each passive IoT device in the paged group of passive IoT devices to perform a corresponding operation based on the request command information or the index corresponding to the request command information carried in the paging message;

[0422] Step 902: Send the paging message to the target node, or send a first paging message, wherein the first paging message is used to instruct the paged passive Internet of Things device or each passive Internet of Things device in the paged group of passive Internet of Things devices to perform a corresponding operation according to the request command information carried by the paging message or the index corresponding to the request command information; wherein the target node includes any one of the following: a base station, a terminal, and an auxiliary node, and the paged passive Internet of Things device or the paged group of passive Internet of Things devices in the first paging message is determined by the target node by sending a second paging message, and the second paging message is used to page the passive Internet of Things device or the group of passive Internet of Things devices.

[0423] In the embodiment of the present disclosure, the core network device determines a paging message. If the paging message is used to page a passive IoT device or a group of passive IoT devices, and / or is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform the operation indicated or requested in the paging message, the core network device can send the paging message to the target node, and the target node sends the paging message to the passive IoT device or the group of passive IoT devices. The paged device (here refers to a passive IoT device or a group of passive IoT devices or all passive IoT devices) can reflect the information back to the target node. The target node reflects the information back to the core network device to determine the passive IoT device being paged and / or the inventory of at least one passive IoT device; if the paging message is used to instruct the paged passive IoT device or each passive IoT device in the paged group of passive IoT devices to perform the operation indicated or requested in the paging message, the core network device can send the paging message to the paged device, and the paged device can respond to the request or instruction in the paging message according to the request command information carried in the paging message or the index corresponding to the request command information, and feedback the response to the core network device.

[0424] Therefore, based on the above-mentioned targeted paging design of at least one or at least one group of passive IoT devices, at least one or at least one group of passive IoT devices is triggered to respond in a targeted manner according to the paging message, thereby achieving the purpose of efficiently finding suitable and / or inventorying passive IoT devices.

[0425] Optionally, the paging message includes at least one of the following: the ID of the paged passive IoT device, the group ID of the paged group passive IoT device, the group mask of the paged group passive IoT device, and the ID list of passive IoT devices in the paged group passive IoT device; or,

[0426] The paging message does not carry the second indication information, and the second indication information includes at least: the ID of the paged passive Internet of Things device, the group ID of the paged group passive Internet of Things device, the group type of the paged group passive Internet of Things device, the group mask of the paged group passive Internet of Things device, and the ID list of the passive Internet of Things devices in the paged group passive Internet of Things device.

[0427] In the embodiment of the present disclosure, the paging message may be sent in a point-to-point manner (if the paging message is used to instruct the specified passive IoT device to perform the operation corresponding to the request command information, the paging message may be sent in a point-to-point manner), or it may be sent in a broadcast manner, wherein the broadcast manner includes a broadcast information manner or a broadcast signal manner. If the paging message is a point-to-point message and carries the ID of the specified passive IoT device, the passive IoT device that receives the paging message can compare its own ID with the ID of the specified passive IoT device. If the comparison is consistent, it indicates that the passive IoT device is the paged passive IoT device; if the paging message is a broadcast message and carries an identifier of the paged passive IoT device or the paged group passive IoT device (for example, ID, group ID, group type, group ID list, group mask, etc.), each passive IoT device that receives the paging message can compare its own ID or the group ID or group type or group mask of the group to which it belongs with the identifier carried in the paging message. If the comparison is consistent, it indicates that the passive IoT device is the paged passive IoT device. device; if the paging message is a broadcast message and does not carry the identification of the passive IoT device being paged or the group passive IoT device being paged, it means that all passive IoT devices receiving the paging message are paged; if the paging message is sent in the form of a broadcast signal, since one broadcast signal corresponds to the group ID or group type of a group of passive IoT devices, the group ID or group type of the group passive IoT device being paged can be determined based on the broadcast signal. The passive IoT device that receives the paging message can compare the group ID to which it belongs with the group ID corresponding to the broadcast signal or compare the group type to which it belongs with the group type corresponding to the broadcast signal. If the comparison is consistent, it means that the passive IoT devices that receive the paging message are the passive IoT devices being paged.

[0428] Therefore, based on the above-mentioned paging method for passive IoT devices or groups of passive IoT devices, the methods of sending paging messages to the target node or at least one passive IoT device can be diverse, and the paging messages sent under different paging methods may correspond to the same or different paging purposes, that is, the paging message can be for paging the device, or it can be for counting or inventorying the paged device.

[0431] Reply request ACK;

[0432] Obtaining information indicated in a memory of the paged passive IoT device;

[0433] Write operation;

[0434] Obtain sensor information of the paged passive IoT device.

[0435] In the disclosed embodiments, if a paging message carries request command information or an index corresponding to the request command information, a passive IoT device that receives the paging message, upon determining that it has been paged, retrieves the request command information in the paging message and responds according to the requirements of the request command information. Thus, by responding to the paging message, an inventory or count of at least one passive IoT device or group of passive IoT devices is achieved.

[0436] Optionally, the paging message includes third indication information, and the third indication information is used to instruct each passive Internet of Things device in the paged group of passive Internet of Things devices or all paged passive Internet of Things devices under the first base station to respond in a staggered manner, and the first base station is the target node.

[0451] In the embodiment of the present disclosure, if the first passive IoT device receives a paging message, it determines whether it is being paged based on the paging message. When the first passive IoT device determines that it is being paged (i.e., the first passive IoT device is the passive IoT device being paged, or any passive IoT device in the group of passive IoT devices being paged), it can read all the information in the paging message; and / or respond to the paging message.

If the comparison is consistent, it is determined that the device is paged;

[0459] If the paging message is a broadcast signal, the group ID or group type corresponding to the broadcast signal is determined based on the correspondence between the broadcast signal and the group ID or group type of the group passive Internet of Things device. If the group ID corresponding to the broadcast signal is consistent with the group ID of the group to which the first passive Internet of Things device belongs, or if the group type corresponding to the broadcast signal is consistent with the group type of the group to which the first passive Internet of Things device belongs, it is determined that the device is being paged.
