[0061] It should be understood that if the A-IoT device provided in the embodiment of the present application adopts backscatter technology, then the A-IoT device can also be called a backscatter communication device or a backscatter device.

[0062] A-IoT devices can be classified based on energy source, energy storage capability, passive or active emission, etc., and include multiple types of devices:

[0063] (1) A passive device has energy storage capability but no independent signal generation / amplification capability and uses backscattering technology for data transmission.

[0064] (2) A semi-passive device also belongs to the category of passive devices. It has energy storage capabilities but no independent signal generation capabilities. It uses backscattering technology for data transmission. The stored energy can be used to amplify the reflected signal.

[0065] (3) An active device has energy storage capability and independent signal generation capability, i.e., it has active radio frequency components for data transmission.

[0068] The communication device 12 may be an access network device, an intermediate node, an auxiliary node, a terminal device, a reader / writer, or a distributed unit (DU) of an access network device, as shown in FIG1 .

[0069] Alternatively, the communication device 12 may include a first communication device and a second communication device, as shown in Figure 2, wherein the first communication device may be an access network device, an intermediate node, an auxiliary node, a terminal device, a reader / writer or a DU, etc., and the second communication device may be a core network device or a central unit (CU) of an access network device.

[0070] Access network equipment may also be referred to as radio access network (RAN) equipment, radio access network functions, or radio access network units.

The auxiliary node may be used to assist the communication between the terminal 11 and other network devices, such as access network devices, but is not limited thereto.

[0072] In radio frequency identification (RFID) systems, the reader / writer is a crucial component. It wirelessly communicates with electronic tags via antennas, enabling the reading and writing of tag identification codes and stored data. The reader / writer communicates with the tag by emitting electromagnetic waves. When these waves encounter the tag, some of the energy is absorbed by the tag, while other energy is scattered in all directions. A small portion of this energy is reflected back to the reader / writer, where it is received and processed, enabling tag identification and data reading. In an RFID system, the reader / writer must be able to transmit and receive electromagnetic waves, as well as process backscattered signals. Furthermore, the reader / writer must be compatible with the tag to ensure stable and reliable communication.

[0073] Among them, the reader / writer can also be called a reader, a query device, a communicator, a scanner, a programmer, a solitary device, a portable reader, an automatic device identification device, etc.

[0078] Before introducing the technical solution of this application, the following will explain the relevant knowledge of this application:

[0079] 1. Backscatter Communication (BSC)

[0080] As mentioned above, the terminal can collect the RF signals sent by the network equipment and use backscatter technology to transmit data.

[0081] Backscatter communication involves a terminal (i.e., a backscatter communication device) utilizing RF signals from other devices or the environment to modulate the signal and transmit its own information. Backscatter, a passive or low-energy technology, is characterized by its ability to transmit its own signal by modifying the characteristics of the received RF signal, such as its phase or amplitude, achieving extremely low or zero power consumption.

[0082] The following uses the reflection scattering communication between the reader and the tag as an example to explain the backscattering communication and its principle:

[0083] Figure 3 is a schematic diagram of backscatter communication. As shown in Figure 3, there are two links between the reader and the tag: Link 1 is the link from the reader to the tag, and Link 2 is the link from the tag to the reader. The reader sends commands to the tag using continuous waves, and the tag transmits data to the reader using backscatter technology.

[0084] Figure 4 is a schematic diagram of the backscatter communication principle provided by this application. As shown in Figure 4, the tag can receive the carrier signal provided by the transmitting baseband of the reader, collect energy through the RF energy collection module, and then supply energy to the modulation module so that the modulation module modulates the carrier signal and performs backscattering.

[0085] The tag controls the circuit's reflection coefficient Γ by adjusting its internal impedance, thereby changing the amplitude, frequency, and phase of the carrier signal to achieve signal modulation. The reflection coefficient Γ can be expressed as: Γ = (Z_1-Z_0) / (Z_1+Z_0) = |Γ|e∧(jθ_T)

[0086] Where Z_0 is the antenna characteristic impedance, Z_1 is the load impedance, and assuming the carrier signal is S_in(t), the tag's output signal is S_out(t) = S_in(t)|Γ|e∧(jθ_T). Therefore, by properly controlling the reflection coefficient Γ, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved.

[0087] 2. Paging Process

[0088] The network can send paging messages to terminals in the idle state (RRC_IDLE), inactive state (RRC_INACTIVE) and connected state (RRC_CONNECTED).

[0089] The paging process can be triggered by the core network to notify a terminal to receive a paging request; or it can be triggered by the access network equipment to notify system information updates and notify the terminal to receive information such as the Earthquake and Tsunami Warning System (ETWS) and the Commercial Mobile Alert System (CMAS).

[0090] In the case where the core network triggers paging, the paging message sent by the core network device to the access network device may carry paging assistance information (Assistance Data for Paging) for paging optimization.

[0091] It should be understood that the paging assistance information may also be referred to as paging assistance data, which is not limited in this embodiment of the present application.

[0092] In some implementations, the paging assistance information includes at least one of the following, but is not limited to: a recommended cell list (Recommended Cell List) and a paging attempt count (Paging Attempt Count).

[0093] As mentioned above, there may be a situation where the network device repeatedly pages some terminals, causing the terminals that have been successfully paged before to need to send a paging response to the network device again. Obviously, the repeated paging response is an invalid paging response, and an invalid paging response will cause invalid task execution for the terminal, such as repeated inventory of some A-IoT devices, repeated transmission of sensor data, repeated positioning and repeated commands, etc.

[0094] For example, in the Internet of Things (IoT), network devices often need to page multiple A-IoT devices simultaneously to perform tasks such as inventory, sensor data transmission, positioning, and command control on these A-IoT devices. Currently, after a network device completes a paging process for multiple A-IoT devices, if paging fails for some A-IoT devices, the network device needs to perform a paging expansion operation or repeatedly page the above-mentioned multiple A-IoT devices, causing the A-IoT devices that have been successfully paged before to need to send a paging response to the network device again. However, this paging response is an invalid paging response. An invalid paging response will cause invalid tasks to be executed on the A-IoT devices, such as repeated inventory, repeated sensor data transmission, repeated positioning, and repeated commands for some A-IoT devices.

[0095] In order to solve the above technical problems, the embodiment of the present application proposes that the terminal only performs a paging response when the paging response conditions are met, thereby avoiding invalid paging responses and further avoiding the execution of invalid tasks.

[0096] The paging method provided in the embodiments of the present application is described in detail below through some embodiments and application scenarios in conjunction with the accompanying drawings.

[0097] FIG5 is an interactive flow chart of a paging method provided in an embodiment of the present application. As shown in FIG5 , the method can be executed by a target terminal and a first communication device. The target terminal can be, but is not limited to, the terminal 11 in FIG1 . The first communication device can be, but is not limited to, the communication device 12 in FIG1 or the first communication device in FIG2 . As shown in FIG5 , the method can include:

[0098] S510: The first communication device sends a first paging message to the target terminal;

[0099] S520: The target terminal sends a first paging response to the first communication device when the paging response condition is met.

[0100] In some implementations, the first paging message includes at least one of the following:

[0101] (1) a value tag for identifying the first paging message;

[0102] (2) a session identifier of the session to which the first paging message belongs;

[0103] (3) a cell identifier of the cell used to send the first paging message;

[0104] (4) a paging range identifier of the first paging message;

[0105] (5) A first indication; wherein the first indication is used to instruct the target terminal to respond to the first paging message, or to instruct the target terminal to detect whether to respond to the first paging message based on other information other than the first indication.

[0106] It should be understood that, since the value tag of the first paging message is used to identify the first paging message, the value tag of the first paging message is also referred to as the identifier of the first paging message.

[0107] In some implementations, the value tag of the first paging message is used to distinguish the first paging message from other paging messages by at least one of the following: the paging purpose and the content carried. It is understood that if multiple paging messages have at least one of the same paging purpose or the same content, then the value tags of the multiple paging messages are the same. The paging purpose can be, but is not limited to, performing a specific task or service. For example, the paging purpose of a paging message may be to inventory A-IoT devices 1, 2, ..., and 10.

[0108] For example, the two paging messages carry the same content, for example, both carry the above value tag, wherein the value tags of the two paging messages are both 1.

[0109] For example, the paging purpose of two paging messages is the same, for example, both are used to inventory A-IoT device 1, A-IoT device 2...A-IoT device 10, wherein the value tags of the two paging messages are both 1.

[0110] For example, the two paging messages carry the same content and have the same paging purpose, for example, both carry the above-mentioned value tag and are used to inventory A-IoT device 1, A-IoT device 2...A-IoT device 10, wherein the value tags of the two paging messages are both 1.

[0111] In some implementations, the session to which the first paging message belongs is used to define a task, which is also called a round of A-IoT process or service, such as a round of inventory process for A-IoT device 1, A-IoT device 2, ..., and A-IoT device 10.

[0112] In some implementations, the session identifier of the session to which the first paging message belongs may also be referred to as the task identifier of the task to which the first paging message belongs, but is not limited thereto.

[0113] It should be understood that different session identifiers are used to identify different sessions. For example, session identifier 01 is used to identify a round of inventory processes for A-IoT devices 1, 2, ..., and 10, while session identifier 02 is used to identify a round of inventory processes for A-IoT devices 20, 21, ..., and 30.

[0114] In some implementations, the cell used to send the first paging message may be one or more cells, but is not limited thereto. For example, cell A is the cell used to send the first paging message.

[0115] In some implementations, the paging range identifier of the first paging message includes at least one of the following, but is not limited to:

[0116] (1) an identifier of the first communication device;

[0117] (2) Identification of the target cell;

[0118] (3) The tracking area (TA) identifier of the target cell;

[0119] (4) The RNA identifier of the radio access network notification area (RAN notification area, RNA) where the target cell is located.

[0120] The paging message sent by the target cell has the same paging purpose as the first paging message, and the target cell may include: a cell used to send the first paging message.

[0121] The target cell is described below as an example:

[0122] For example, cell A sends paging message 1, the purpose of which is to take inventory of A-IoT device 1, A-IoT device 2...A-IoT device 10, while the purpose of the paging message sent by cell B is also to take inventory of A-IoT device 1, A-IoT device 2...A-IoT device 10. Based on this, the target cells include: cell A and cell B.

[0123] It should be understood that, when the first instruction is used to instruct the target terminal to respond to the first paging message, it indicates that the first communication device forcibly instructs the target terminal to respond to the first paging message.

[0124] In some possible implementations, the first indication instructs the target terminal to detect whether to respond to the first paging message based on other information other than the first indication, including: the first indication instructs the target terminal to detect whether to respond to the first paging message based on at least one item of information in the first paging message other than the first indication, wherein the first indication may clearly indicate on which information the target terminal detects whether to respond to the first paging message, or may not clearly indicate, but the target terminal decides by itself on which information to use to detect whether to respond to the first paging message, or, the first paging message carries information other than the first indication, and the target terminal uses that information to detect whether to respond to the first paging message.

[0125] For example, if the first indication instructs the target terminal to detect whether to respond to the first paging message based on the value tag of the first paging message, the target terminal may detect whether to respond to the first paging message based on the value tag of the first paging message.

[0126] For example, if the first indication indicates whether to respond to the first paging message based on other information except the first indication, the target terminal may decide by itself whether to respond to the first paging message based on the value tag of the first paging message.

[0127] For example, if the first indication indicates whether to respond to the first paging message based on other information other than the first indication, and the first paging message carries the first indication, the value tag of the first paging message and the session identifier of the session to which the first paging message belongs, then the target terminal can detect whether to respond to the first paging message based on the value tag of the first paging message and the session identifier of the session to which the first paging message belongs.

[0128] In some implementations, the first indication is used to instruct the target terminal to respond to the first paging message, and may also be referred to as the first indication being used to instruct the target terminal to ignore other information except the first indication.

[0129] In some implementations, the paging response condition includes at least one of the following:

[0130] (1) The first paging message is the first paging message received by the target terminal;

[0131] (2) The value tag of the first paging message is different from the value tag of the second paging message previously received by the target terminal;

[0132] (3) The first paging timer times out;

[0133] (4) The first paging timer is configured and the first paging timer is not started;

[0134] (5) The session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs;

[0135] (6) The cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message;

[0136] (7) The paging range identifier of the first paging message is different from the paging range identifier of the second paging message;

[0137] (8) The paging range identified by the paging range identifier of the first paging message does not include the paging range identified by the paging range identifier of the second paging message;

[0138] (9) The paging range identified by the paging range identifier of the first paging message does not include the cell used to send the second paging message;

[0139] (10) The first indication is used to instruct the target terminal to respond to the first paging message.

[0140] It should be understood that one of the paging response conditions (3) and (4) can be selected. One of the paging response conditions (7), (8) and (9) can be selected.

[0141] It should be understood that the embodiments of the present application mainly focus on whether to respond to repeated paging messages. Based on this, if the first paging message is the first paging message received by the target terminal, then the target terminal is considered to meet the paging response conditions. In this case, the target terminal can send a first paging response corresponding to the first paging message to the first communication device.

[0142] In some implementations, when a target terminal receives any paging message, it may store some or all of the information in the paging message. Therefore, the first paging message being the first paging message received by the target terminal is also referred to as information indicating that the target terminal has not stored any paging messages. Alternatively, the first paging message received by the target terminal is a paging message received when the target terminal has not stored any paging messages.

[0143] It should be understood that the second paging message may be any paging message received by the target terminal before receiving the first paging message, for example, it may be the last paging message received by the target terminal.

[0144] In some implementations, when the target terminal receives any paging message, it can store part or all of the information in the paging message. The value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time. This is also called the value tag of the first paging message is different from the value tag it saved most recently, or the value tag of the first paging message is different from the value tag it saved.

[0145] For example, assuming that the target terminal receives paging message 1, and the last paging message it received was paging message 2, the target terminal believes that the two paging messages are not duplicate paging messages. Based on this, the target terminal can make a paging response to paging message 1 for the paging message 2 received this time.

[0146] In some implementations, the paging method further includes: the target terminal receiving a second paging message, wherein the second paging message includes: information of the first paging timer.

[0147] In some implementations, the information of the first paging timer includes at least any one of the following, but is not limited to:

[0148] (1) A second indication; wherein the second indication is used to indicate prohibiting a response to a paging message received during the running of the first paging timer; or, the second indication is used to indicate prohibiting a paging response during the running of the first paging timer.

[0149] (2) The duration of the first paging timer.

[0150] The second instruction is exemplified below:

[0151] For example, assuming that the target terminal receives paging message 1 during the operation of the first paging timer, and the second indication is used to indicate prohibition of responding to the paging message received during the operation of the first paging timer, then the target terminal cannot respond to the paging message 1 during the operation of the first paging timer.

[0152] For example, assuming that the target terminal receives paging message 1, and the second indication is used to indicate prohibition of performing a paging response during the running of the first paging timer, the target terminal cannot respond to the paging message 1 during the running of the first paging timer.

[0153] In some implementations, if the information of the first paging timer does not include the above-mentioned second indication, the target terminal may also prohibit by default responding to the paging message received during the operation of the first paging timer, or prohibit by default performing a paging response during the operation of the first paging timer.

[0154] In some implementations, if the information of the first paging timer does not include the duration of the first paging timer, the duration of the first paging timer may be predefined, configured by the first communication device, or configured by the core network, but is not limited thereto.

[0155] In some implementations, the first paging timer is started in any of the following situations:

[0156] (1) The target terminal receives the second paging message;

[0157] (2) determining that the at least one terminal identified by the identifier of the at least one terminal includes a target terminal, wherein the identifier of the at least one terminal is included in the second paging message;

[0158] (3) After the target terminal sends a second paging response corresponding to the second paging message to the first communication device.

[0159] In the embodiment of the present application, the first paging timer is started in any of the above situations, which can also be referred to as the first paging timer being started in any of the above situations when it is configured and not running.

[0160] In some implementations, the identifier of the at least one terminal is any one of the following: a group identifier of a terminal group constituted by the at least one terminal; or an identifier of each of the at least one terminal.

[0161] For example, A-IoT device 1, A-IoT device 2, ..., A-IoT device 10 constitute a terminal group, and the group identifier of the terminal group is 001.

[0162] For example, the identifiers of A-IoT device 1, A-IoT device 2, ..., and A-IoT device 10 are 1, 2, ..., 10, respectively.

[0163] The following is an exemplary description of a prohibit paging response based on the start-up condition of the first paging timer:

[0164] For example, in the case where the second indication is used to indicate prohibition of responding to a paging message received during the operation of the first paging timer, assuming that the target terminal starts the first paging timer after receiving paging message 1, and the target terminal receives paging message 2 during the operation of the first paging timer, then the target terminal does not respond to the paging message 2.

[0165] For example, in the case where the second indication is used to indicate prohibition of responding to a paging message received during the operation of the first paging timer, assuming that after the target terminal receives paging message 1, the paging message 1 includes the identifier of at least one terminal, and the target terminal determines that at least one terminal identified by the identifier of at least one terminal includes the target terminal, indicating that the target terminal is paged, then the target terminal starts the first paging timer, assuming that the target terminal receives paging message 2 during the operation of the first paging timer, then the target terminal does not respond to the paging message 2.

[0166] For example, in the case where the second indication is used to indicate prohibition of responding to a paging message received during the operation of the first paging timer, after the target terminal sends the paging response corresponding to paging message 1, it can start the first paging timer. Assuming that the target terminal receives paging message 2 during the operation of the first paging timer, the target terminal does not respond to the paging message 2.

[0167] For example, in the case where the second indication is used to indicate prohibition of executing a paging response during the operation of the first paging timer, assuming that the target terminal starts the first paging timer after receiving the paging message 1, and then the target terminal receives the paging message 2, then the target terminal does not respond to the paging message 2 during the operation of the first paging timer.

[0168] For example, in the case where the second indication is used to indicate prohibition of executing a paging response during the operation of the first paging timer, assuming that after the target terminal receives paging message 1, the paging message 1 includes the identifier of at least one terminal, and the target terminal determines that at least one terminal identified by the identifier of at least one terminal includes the target terminal, indicating that the target terminal is paged, then the target terminal starts the first paging timer, assuming that the target terminal subsequently receives paging message 2, then the target terminal does not respond to the paging message 2 during the operation of the first paging timer.

[0169] For example, in the case where the second indication is used to indicate prohibition of executing a paging response during the operation of the first paging timer, after the target terminal sends the paging response corresponding to the paging message 1, it can start the first paging timer. Assuming that the target terminal subsequently receives a paging message 2, the target terminal does not respond to the paging message 2 during the operation of the first paging timer.

[0170] It should be understood that the expiration of the first paging timer indicates that the interval between the two paging messages is long enough. In other words, after the target terminal successfully completes a paging response, it does not need to respond to other paging messages for a period of time. The two paging messages can come from the same cell or different cells or involve the same service or process. The two paging messages can have the same session identifier or value tag, thereby avoiding multiple paging responses, or avoiding multiple paging responses for the same service or process, or avoiding multiple paging responses for the same paging purpose.

[0171] For example, in the case where the second indication is used to indicate prohibition of responding to a paging message received during the operation of the first paging timer, the target terminal starts the first paging timer after receiving paging message 1. Assuming that the target terminal receives paging message 2 after the first paging timer expires, the target terminal can respond to paging message 2.

[0172] For example, in the case where the second indication is used to indicate prohibition of responding to a paging message received during the operation of the first paging timer, assuming that the target terminal determines that at least one terminal identified by the identifier of at least one terminal includes the target terminal, then it means that the target terminal is paged. At this time, the target terminal starts the first paging timer. assuming that the target terminal receives paging message 2 after the first paging timer expires, then the target terminal can respond to paging message 2.

[0173] For example, in the case where the second indication is used to indicate prohibition of responding to a paging message received during the operation of the first paging timer, after the target terminal sends the paging response corresponding to paging message 1, it can start the first paging timer. Assuming that the target terminal receives paging message 2 after the first paging timer expires, the target terminal can respond to paging message 2.

[0174] For example, in the case where the second indication is used to indicate prohibition of executing a paging response during the operation of the first paging timer, assuming that the target terminal starts the first paging timer after receiving the paging message 1, and then the target terminal receives the paging message 2, then the target terminal responds to the paging message 2 after the first paging timer times out.

[0175] For example, in the case where the second indication is used to indicate prohibition of executing a paging response during the operation of the first paging timer, assuming that after the target terminal receives paging message 1, the paging message 1 includes the identifier of at least one terminal, and the target terminal determines that at least one terminal identified by the identifier of at least one terminal includes the target terminal, indicating that the target terminal is paged, then the target terminal starts the first paging timer, assuming that the target terminal subsequently receives paging message 2, then the target terminal responds to the paging message 2 after the first paging timer expires.

[0176] For example, in the case where the second indication is used to indicate prohibition of executing a paging response during the operation of the first paging timer, after the target terminal sends the paging response corresponding to the paging message 1, it can start the first paging timer. Assuming that the target terminal subsequently receives the paging message 2, the target terminal responds to the paging message 2 after the first paging timer expires.

[0177] It should be understood that the first paging timer is configured and the first paging timer is not turned on, which indicates that the first paging message is the first paging message received by the target terminal. In this case, the target terminal is considered to meet the paging response conditions. In this case, the target terminal can send a first paging response corresponding to the first paging message to the first communication device.

[0178] In some implementations, the first paging message includes information of a second paging timer.

[0179] In some implementations, the information of the second paging timer includes at least any one of the following, but is not limited to:

[0180] (1) A third indication; wherein the third indication is used to indicate prohibiting a response to a paging message received during the second paging timer; or, the third indication is used to indicate prohibiting a paging response during the second paging timer.

[0181] (2) The duration of the second paging timer.

[0182] In some implementations, the second paging timer is started in any of the following situations:

[0183] (1) The target terminal receives a first paging message;

[0184] (2) determining that the at least one terminal identified by the identifier of the at least one terminal includes a target terminal, wherein the identifier of the at least one terminal is included in the first paging message;

[0185] (3) After the target terminal sends a first paging response to the first communication device.

[0186] It should be understood that the explanation of the second paging timer can refer to the explanation of the first paging timer, and this embodiment of the present application will not be repeated here.

[0187] It should be understood that the fact that the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs indicates that the session to which the first paging message belongs is different from the session to which the second paging message belongs, or that the service involved in the first paging message is different from the service involved in the second paging message.

[0188] For example, the session ID of the session to which the first paging message belongs is 01, which is used to identify a round of inventory processes for A-IoT devices 1, 2, ..., and 10. The session ID of the session to which the second paging message belongs is 02. This second paging message is the last paging message received by the target terminal, and is used to identify a round of inventory processes for A-IoT devices 21, 22, ..., and 30. If the two session IDs are different, the target terminal can respond to the first paging message.

[0189] The following is an exemplary description of item (6) of the paging response condition:

[0190] For example, the cell identifier of the cell used to send the first paging message is A, and the cell identifier of the cell used to send the second paging message is B, wherein the second paging message is the paging message received by the target terminal last time, then the target terminal can respond to the first paging message.

[0191] The following is an exemplary description of item (7) of the paging response condition:

[0192] For example, the paging range identifier of the first paging message is cell identifier: A and B, and the paging range identifier of the second paging message is cell identifier: A, which are different. Among them, the second paging message is the paging message received by the target terminal last time, then the target terminal can respond to the first paging message.

[0193] The following is an exemplary description of item (8) of the paging response condition:

[0194] For example, the paging range identifier of the first paging message is the cell identifier: A and B, and the paging range identifier of the second paging message is the cell identifier: C, wherein the second paging message is the paging message received by the target terminal last time. Since the paging range identified by the paging range identifier of the first paging message does not include the paging range identified by the paging range identifier of the second paging message, the target terminal can respond to the first paging message.

[0195] The following is an exemplary description of item (9) of the paging response condition:

[0196] For example, the paging range identifier of the first paging message is the cell identifier: A and B, and the paging range identifier of the second paging message is the cell identifier: C, wherein the second paging message is the paging message received by the target terminal last time. Since the paging range identified by the paging range identifier of the first paging message does not include the cell used to send the second paging message, the target terminal can respond to the first paging message.

[0197] The following is an example of combining multiple conditions in a paging response:

[0198] Assume that the paging response conditions include: the value tag of the first paging message is different from the value tag of the second paging message last received by the target terminal; and the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs. In this embodiment of the present application, the second paging message is the paging message last received by the target terminal, and this will not be further described below.

[0199] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 2, the session identifier of the session to which the first paging message belongs is 01, and the session identifier of the session to which the second paging message belongs is 02. Since the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; and the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs, the target terminal believes that the first paging message and the second paging message are not duplicate paging, and it can respond to the first paging message.

[0200] It is assumed that the paging response conditions include: the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message.

[0201] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 2, the cell identifier of the cell used to send the first paging message is A, and the cell identifier of the cell used to send the second paging message is B. Since the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message, then the target terminal believes that the first paging message and the second paging message are not duplicate paging, and it can respond to the first paging message.

[0202] It is assumed that the paging response conditions include: the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; and the paging range identifier of the first paging message is different from the paging range identifier of the second paging message.

[0203] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 2, the paging range identifier of the first paging message is the cell identifier: A and B, and the paging range identifier of the second paging message is the cell identifier: A. Since the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the paging range identifier of the first paging message is different from the paging range identifier of the second paging message, then the target terminal believes that the first paging message and the second paging message are not duplicate paging, and it can respond to the first paging message.

[0204] It is assumed that the paging response conditions include: the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs; the cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message.

[0205] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 2, the session identifier of the session to which the first paging message belongs is 01, the session identifier of the session to which the second paging message belongs is 02, the cell identifier of the cell used to send the first paging message is A, and the cell identifier of the cell used to send the second paging message is B. Since the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs; the cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message, then the target terminal believes that the first paging message and the second paging message are not duplicate paging, and it can respond to the first paging message.

[0206] It is assumed that the paging response conditions include: the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs; the paging range identifier of the first paging message is different from the paging range identifier of the second paging message.

[0207] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 2, the session identifier of the session to which the first paging message belongs is 01, the session identifier of the session to which the second paging message belongs is 02, the paging range identifier of the first paging message is the cell identifier: A and B, and the paging range identifier of the second paging message is the cell identifier: A. Since the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs; the paging range identifier of the first paging message is different from the paging range identifier of the second paging message, then the target terminal believes that the first paging message and the second paging message are not duplicate paging, and it can respond to the first paging message.

[0208] It is assumed that the paging response conditions include: the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message; the paging range identifier of the first paging message is different from the paging range identifier of the second paging message.

[0209] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 2, the cell identifier of the cell used to send the first paging message is A, the cell identifier of the cell used to send the second paging message is B, the paging range identifier of the first paging message is cell identifiers: A and B, and the paging range identifier of the second paging message is cell identifier: A. Since the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message; the paging range identifier of the first paging message is different from the paging range identifier of the second paging message, then the target terminal believes that the first paging message and the second paging message are not duplicate paging, and it can respond to the first paging message.

[0210] It is assumed that the paging response conditions include: the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs; the cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message; the paging range identifier of the first paging message is different from the paging range identifier of the second paging message.

[0211] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 2, the session identifier of the session to which the first paging message belongs is 01, the session identifier of the session to which the second paging message belongs is 02, the cell identifier of the cell used to send the first paging message is A, the cell identifier of the cell used to send the second paging message is B, the paging range identifier of the first paging message is cell identifiers: A and B, and the paging range identifier of the second paging message is cell identifier: A. Since the value tag of the first paging message is different from the value tag of the second paging message received by the target terminal last time; the session identifier of the session to which the first paging message belongs is different from the session identifier of the session to which the second paging message belongs; the cell identifier of the cell used to send the first paging message is different from the cell identifier of the cell used to send the second paging message; the paging range identifier of the first paging message is different from the paging range identifier of the second paging message, then the target terminal believes that the first paging message and the second paging message are not duplicate paging, and it can respond to the first paging message.

[0212] In some implementations, after the target terminal sends a first paging response to the first communication device when a paging response condition is met, the target terminal may store some or all of the information in the first paging message. For example, the target terminal may store the value tag of the first paging message, the session identifier of the corresponding session, etc., so that when the target terminal receives the next paging message, it can refer to the information in the first paging message to determine whether to respond to the next paging message.

[0213] It should be understood that in an embodiment of the present application, after the first communication device performs a round of paging on multiple terminals, if paging fails for some terminals, the first communication device can repeat the paging for these terminals, or perform an expanded paging operation, for example, the A-IoT devices 1-10 are paged before, and the A-IoT devices 1-10 and A-IoT devices 21-30 are paged later.

[0214] In some implementations, when the paging response condition is not satisfied, the target terminal does not send the first paging response to the first communication device.

[0215] In some implementations, when a paging non-response condition is met, the target terminal does not send the first paging response to the first communication device.

[0216] In some implementations, the paging non-response condition includes at least one of the following, but is not limited to:

[0217] (1) The value tag of the first paging message is the same as the value tag of the second paging message previously received by the target terminal;

[0218] (2) The first paging timer does not time out;

[0219] (3) The session identifier of the session to which the first paging message belongs is the same as the session identifier of the session to which the second paging message belongs;

[0220] (4) The cell identifier of the cell used to send the first paging message is the same as the cell identifier of the cell used to send the second paging message;

[0221] (5) The paging range identifier of the first paging message is the same as the paging range identifier of the second paging message;

[0222] (6) The paging range identified by the paging range identifier of the first paging message includes the paging range identified by the paging range identifier of the second paging message;

[0223] (7) The paging range identified by the paging range identifier of the first paging message includes the cell used to send the second paging message;

[0224] (8) The fourth indication is used to instruct the target terminal not to respond to the first paging message.

[0225] It should be understood that any one of the items (5), (6) and (7) in the paging non-response condition can be selected.

[0226] The following is an exemplary description of item (1) of the paging non-response condition:

[0227] For example, assuming that the target terminal receives paging message 1, and the last paging message it received was also paging message 1, the target terminal considers that the two paging messages are duplicate paging messages. Based on this, the target terminal does not respond to the paging message 1 received again.

[0228] The following is an exemplary description of item (2) of the paging non-response condition:

[0229] For example, assuming that the target terminal receives the paging message 1 during the running of the first paging timer, that is, the first timer has not timed out, the target terminal does not respond to the paging message 1.

[0230] The following is an exemplary description of item (3) of the paging no response condition:

[0231] For example, assuming that the session identifier of the session to which the first paging message belongs is the same as the session identifier of the session to which the second paging message belongs, both are 01, then the target terminal may not respond to the first paging message.

[0232] The following is an exemplary description of item (4) of the paging non-response condition:

[0233] For example, the cell identifier of the cell used to send the first paging message is A, and the cell identifier of the cell used to send the second paging message is also A, then the target terminal may not respond to the first paging message.

[0234] The following is an exemplary description of item (5) of the paging no response condition:

[0235] For example, the paging range identifier of the first paging message is cell identifiers: A and B, and the paging range identifier of the second paging message is cell identifiers: A and B, which are the same, so the target terminal may not respond to the first paging message.

[0236] The following is an exemplary description of item (6) of the paging non-response condition:

[0237] For example, the paging range identifier of the first paging message is the cell identifier: A and B, and the paging range identifier of the second paging message is the cell identifier: A. Since the paging range identified by the paging range identifier of the first paging message includes the paging range identified by the paging range identifier of the second paging message, the target terminal may not respond to the first paging message.

[0238] The following is an exemplary description of item (7) of the paging non-response condition:

[0239] For example, the paging range identifier of the first paging message is the cell identifier: A and B, and the paging range identifier of the second paging message is the cell identifier: A. Since the paging range identified by the paging range identifier of the first paging message includes the cell used to send the second paging message, the target terminal may not respond to the first paging message.

[0240] It should be understood that, when the fourth indication is used to instruct the target terminal not to respond to the first paging message, it indicates that the first communication device forcibly instructs the target terminal not to respond to the first paging message.

[0241] The following is an example of a combination of multiple conditions in the paging no response condition:

[0242] It is assumed that the paging non-response conditions include: the value tag of the first paging message is the same as the value tag of the second paging message received by the target terminal last time; the session identifier of the session to which the first paging message belongs is the same as the session identifier of the session to which the second paging message belongs.

[0243] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 1, the session identifier of the session to which the first paging message belongs is 01, and the session identifier of the session to which the second paging message belongs is 01. Since the value tag of the first paging message is the same as the value tag of the second paging message received by the target terminal last time; and the session identifier of the session to which the first paging message belongs is the same as the session identifier of the session to which the second paging message belongs, the target terminal considers that the first paging message and the second paging message are duplicate pagings, and it may not respond to the first paging message.

[0244] It is assumed that the paging non-response conditions include: the value tag of the first paging message is the same as the value tag of the second paging message received by the target terminal last time; the cell identifier of the cell used to send the first paging message is the same as the cell identifier of the cell used to send the second paging message.

[0245] For example, the value tag of the first paging message is 1, the value tag of the second paging message is 1, the cell identifier of the cell used to send the first paging message is A, and the cell identifier of the cell used to send the second paging message is A. Since the value tag of the first paging message is the same as the value tag of the second paging message received by the target terminal last time; the cell identifier of the cell used to send the first paging message is the same as the cell identifier of the cell used to send the second paging message, then the target terminal considers that the first paging message and the second paging message are duplicate paging, and it may not respond to the first paging message.

[0246] It is assumed that the paging non-response condition includes: the value tag of the first paging message is the same as the value tag of the second paging message received by the target terminal last time; and the paging range identifier of the first paging message is the same as the paging range identifier of the second paging message.
