[0050] In order for those skilled in the art to better understand the embodiments of the present application, the following is first described.

[0051] 1. Ambient IoT (Ambient Internet of Things);

[0052] Ambient IoT is a new 3rd Generation Partnership Project (3GPP) IoT technology to be studied. Ambient IoT devices have ultra-low complexity and ultra-low power consumption.

[0053] Ambient IoT, also known as Ambient power-enabled IoT, is an IoT service in which IoT devices are powered by energy harvesting, and the IoT devices have no battery or have limited energy storage capability (for example, using a capacitor). Energy sources for energy harvesting include radio waves, light, motion, heat or other suitable energy sources.

[0054] Low-power IoT devices are IoT devices with low overall power consumption, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, the communication energy can come from the environment, such as wind energy, kinetic energy, thermal energy, radio frequency (RF) signals, etc. It can also be called Ambient IoT device or passive IoT device or responder device. The signal transmission method of such devices has the following characteristics:

[0055] (1) It can backscatter RF signals for signal transmission; such devices can also be called electronic tags, RF tags, i.e. tags (Tag) in Radio Frequency Identification (RFID);

[0056] (2) Some active tags have the ability to generate signals actively, but in order to achieve low power consumption of the device, it is generally lower than 0 dBm, for example, less than or equal to -10 dBm.

[0057] Ambient IoT terminals can be classified based on energy source, energy storage capability, passive or active transmission, etc., and specifically include three types of devices:

[0058] Device Type A (Device Type A): belongs to passive device (Passive Device), no energy storage, no independent signal generation / amplification, i.e. backscatter transmission.

[0059] Device Type B (Device Type B): a semi-passive device (semi-passive Device), also belongs to the large category of passive devices (Passive Device). It has energy storage and no independent signal generation, i.e. backscatter transmission. The use of stored energy can include amplification of reflected signals.

[0060] Device Type C (Device Type C): an active device (Active Device) with energy storage and independent signal generation, i.e. active radio frequency components for transmission.

[0061] 2. Information transmission between RFID reader and Tag;

[0062] RFID is a traditional backscatter communication system, and its main design goal is to identify and read data from backscatter communication (BSC) devices (i.e. Tags) within the coverage of the reader. Since RFID was initially applied to the automatic inventory of a large number of goods, the process of identifying and reading data from Tags is also called inventory.

[0063] Taking the EPC C1G2 RFID system defined in ISO 18000-6c as an example, after the reader sends a query instruction (Query), the Tag responds with a reply (Reply). Taking RN16 as an example, the Tag generates a 16-bit random number and sends it to the reader. Then the reader sends the sequence to the Tag through an ACK instruction, and after the Tag successfully verifies the RN16 in the ACK, it sends subsequent data (such as PC / XPC, EPC, etc.) to the reader.

[0064] The instructions for the operation of the reader are shown in Table 1.

[0065] Table 1

[0066] 3, AIoT Topology (network topology);

[0067] As shown in FIG. 2 and FIG. 3, they are the two most typical network topologies in AIoT communication. Among them, the topology Topo1 shown in FIG. 2 is a scenario in which the base station acts as a reader and directly communicates with the AIoT device. The topology Topo2 shown in FIG. 3 is a scenario in which the base station communicates with the AIoT device through an intermediate node. The intermediate node can be a terminal reader (UE reader), and the UE reader and the base station multiplex the existing Uu interface.

[0068] In the related art, there is no paging method for AIoT terminal readers. Moreover, since the paging process of the existing AIoT interface is only for AIoT devices, the purpose is to find a specific AIoT device, and it is only applicable to the scenario in which the reader sends a paging to the AIoT device. In some scenarios, the coverage of the gNB is limited and cannot directly find the AIoT device, and an intermediate node such as a UE is needed to assist communication. At this time, the purpose of paging is to find a UE node that can act as a UE reader. It can be seen that the paging process of the AIoT interface is not suitable for the paging of the UE reader. In addition, the paging process of the multiplexed side link (SL) relay is also not suitable, because in the SL relay architecture, the remote UE is essentially also a UE node, and the paging process of the Uu interface is different from the AIoT scenario and requirements. Therefore, the paging of the UE reader cannot directly multiplex the paging process of the SL relay.

[0069] The paging method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and their application scenarios.

[0070] As shown in FIG. 4, the present application provides a paging method, which is executed by a terminal, and the method comprises:

[0071] Step 401: obtaining a first paging message, the first paging message is used for paging a terminal, wherein the terminal acts as an environmental Internet of Things (AIoT) reader to assist an AIoT device in AIoT communication.

[0072] In this step, the terminal obtains a first paging message sent by a first network side device. The first network side device can be a base station.

[0073] In the embodiments of the present application, when the terminal assists the AIoT device to perform AIoT communication as an AIoT reader-writer, the terminal can also be described as a terminal reader-writer, that is, the terminal described as an AIoT reader-writer is a terminal reader-writer.

[0074] Step 402: in the case of determining to respond to the first paging message, initiating an access network procedure or initiating a network connection recovery procedure.

[0075] For example, for the terminal in the idle state, in the case of determining to respond to the first paging message, initiating an access network procedure.

[0076] For example, for the terminal in the inactive state, in the case of determining to respond to the first paging message, initiating a network connection recovery procedure.

[0077] In some embodiments of the present application, the terminal determines whether to respond to the first paging message according to its own situation, for example, if the power of the terminal is less than a preset power, or the terminal does not meet the conditions of the terminal reader-writer or the AIoT device being paged is not within the proximity range of the terminal, the terminal does not respond to the first paging message, otherwise, the terminal responds to the first paging message.

[0078] In the above scheme, the terminal acquires a first paging message, the first paging message is used to page the terminal, wherein the terminal assists an AIoT device to perform AIoT communication as an environmental Internet of Things (AIoT) reader-writer; in the case of determining to respond to the first paging message, initiating an access network procedure or initiating a network connection recovery procedure. In this scheme, the terminal can enter a connected state based on the first paging message, and assist the AIoT device to perform AIoT communication as an AIoT reader-writer, that is, the terminal is a communication node of the network side device and the AIoT device for AIoT communication, and the paging of the AIoT device is realized through the terminal reader-writer, thereby expanding the coverage range of the network side device and avoiding the problem that the network side device cannot page the AIoT device due to limited coverage range.

[0079] As an optional implementation manner, the first paging message comprises:

[0080] A terminal identifier of the terminal being paged;

[0081] First indication information, the first indication information is used to indicate that the terminal being paged is an AIoT reader-writer.

[0082] The first paging message comprises a terminal identifier of at least one terminal being paged, for example, the first paging message comprises a terminal identifier list (UE ID list).

[0083] In some embodiments of the present application, in the case that there is a certain association relationship between the terminal and the AIoT device, the terminal identifier of the paged terminal is carried in the first paging message. The association relationship can be pre-configured or exist in some specific scenarios. Through the first paging message, the first network side device can reuse the existing paging process of the base station to the terminal.

[0084] As another optional implementation, the first paging message includes at least one of the following:

[0085] The first item: a paging identifier, which is used to indicate the terminal that the paging object is the terminal as an AIoT reader.

[0086] Based on the paging identifier, the terminal determines that the base station needs to find the terminal with terminal reader capability to assist the AIoT device in AIoT communication.

[0087] The second item: group information of the terminal, which is the group information when the terminal is an AIoT reader.

[0088] For example, the terminal reader can be grouped or managed in the core network process or service layer process such as the registration process or group management process, and the terminal reader can belong to a specific group or serve a specific AIoT service or a specific AIoT device; that is, the above-mentioned group information is associated with a specific AIoT service or a specific AIoT device.

[0089] The third item: AIoT service information.

[0090] For example, the AIoT service information includes service type, AIoT device information corresponding to the AIoT service, etc.

[0091] Based on the AIoT service information, the terminal determines whether it can meet the requirement of providing the AIoT service, and further determines whether to respond to the first paging message.

[0092] The fourth item: information of the paged AIoT device.

[0093] For example, the number, location, AIoT filtering information or MASK information of the AIoT device, etc. The MASK information can be understood as the condition information of the AIoT device. For example, the MASK information is the AIoT device whose first 20 bits of the Electronic Product Code (EPC) ID are a specified value.

[0094] Based on the information of the paged AIoT device, the terminal can determine whether the paged AIoT device is located in the proximity of the terminal, and further determine whether to respond to the first paging message.

[0095] In the embodiments of the present application, based on the content of the first paging message, the terminal can determine that the base station needs to find a terminal-assisted AIoT device with a terminal reader / writer capability for AIoT communication, and further determine whether the terminal responds to the first paging message.

[0096] Optionally, the method of the embodiments of the present application further comprises:

[0097] obtaining dedicated paging information;

[0098] obtaining the first paging message according to the dedicated paging information;

[0099] The dedicated paging information includes at least one of the following:

[0100] a dedicated paging period, the dedicated paging period being a period for the first network side device to page an AIoT reader / writer, the AIoT reader / writer including a terminal;

[0101] a dedicated paging time domain pattern, the dedicated paging time domain pattern being used to indicate a time domain position parameter for the first network side device to page the AIoT reader / writer;

[0102] a dedicated paging identifier, the dedicated paging identifier being a scheduling identifier for the first network side device to page the AIoT reader / writer, for example, the scheduling identifier being a first paging radio network temporary identifier (P-RNTI) value, the first P-RNTI being used to scramble a PDCCH to schedule a dedicated paging;

[0103] a dedicated paging modulation and coding parameter, the dedicated paging modulation and coding parameter being a modulation and coding parameter for the first network side device to page the AIoT reader / writer;

[0104] dedicated paging resource information, the dedicated paging resource information being resource information for the first network side device to page the AIoT reader / writer.

[0105] In the embodiments of the present application, the above-mentioned dedicated paging information can be transmitted through a system information block (SIB) or dedicated signaling.

[0106] The above-mentioned dedicated paging information is paging information for a terminal reader / writer, and by configuring the above-mentioned dedicated paging information, the terminal reader / writer can listen to the first paging information based on the dedicated paging information, while a non-terminal reader / writer can ignore the dedicated paging information, thereby avoiding unnecessary listening and reducing the impact on the non-terminal reader / writer, which is conducive to saving the energy consumption of the non-terminal reader / writer.

[0107] Optionally, the method of the embodiments of the present application further comprises:

[0108] obtaining first condition information, wherein the first condition information is used by the terminal to determine whether the terminal can serve as an AIoT reader;

[0109] in a case where it is determined according to the first condition information configured by the first network side device that the terminal can serve as an AIoT reader, determining whether to respond to the first paging message.

[0110] In the embodiments of the present application, the terminal first determines whether the condition for serving as an AIoT reader is met based on the first condition information, and then determines whether to respond to the first paging message according to its own condition such as power in a case where the condition for serving as an AIoT reader is met, initiates an initial access procedure or initiates a network connection recovery procedure to the network if it is determined to respond to the first paging message, and enters a connected state; and notifies the network if the first condition information is not met, so as to avoid wasting of paging resources by the network.

[0111] Optionally, the first condition information comprises at least one of the following:

[0112] the first item: Uu channel condition information, wherein the Uu channel condition information is Uu channel condition information required by the terminal to serve as an AIoT reader.

[0113] For example, the Uu channel condition information comprises a reference signal received power (RSRP) threshold, the RSRP can be a minimum RSRP threshold, when the Uu link RSRP of the UE is lower than the threshold, it indicates that the coverage of the UE is poor, and thus the UE is not suitable to serve as a UE reader; or the Uu channel condition information can comprise a maximum RSRP threshold, when the Uu link RSRP of the UE is higher than the threshold, it indicates that the UE is located in the center of the cell, and the coverage of the UE is limited, and the AIoT device within the coverage radius of the UE can be directly served as a reader by the gNB, so that the transmission efficiency and latency performance can be effectively improved based on the RSRP.

[0114] the second item: AIoT interface condition information, wherein the AIoT interface condition information is AIoT interface condition information required by the terminal to serve as an AIoT reader.

[0115] For example, the AIoT interface condition information comprises at least one of a transmission power level of an AIoT interface, a receiving capability, a transmission capability, and a link quality threshold of the AIoT interface. For example, when there is a certain binding relationship between the UE reader and the AIoT device, the link quality threshold is too low in previous or last communication, and it is determined that the UE reader cannot perform communication assistance for the device.

[0116] In the embodiments of the present application, the first network side device can send the first condition information above through SIB or dedicated signaling.

[0117] Optionally, the method further comprises:

[0118] initiating an access network procedure according to the access information sent by the first network side device;

[0119] The access information comprises network access information when the terminal is an AIoT reader / writer.

[0120] In the embodiments of the present application, the access information for the terminal reader / writer is configured, for example, the access information comprises access level and access parameter, if the special access information is not configured, the UE uses the default access information, for example, similar to the access parameter when downlink data arrives. Through the access information, the terminal reader / writer can enter the connected state, and further can assist the AIoT device to perform AIoT communication.

[0121] In the embodiments of the present application, the first network side device can send the access information above through SIB or dedicated signaling.

[0122] Optionally, the method of the embodiments of the present application further comprises:

[0123] In the case of determining not to respond to the first paging message, a paging rejection message or a paging restriction message is sent, the paging rejection message is used to indicate to the first network side device that the terminal does not accept the paging corresponding to the first paging message, and the paging restriction message is used to restrict the first network side device from sending the first paging message to the terminal.

[0124] In some embodiments of the present application, the paging rejection message or the paging restriction message can be carried in a service request through a non-access layer (Non-Access Stratum, NAS) procedure, or the paging rejection message or the paging restriction message is sent in a random access (Random Access Channel, RACH) procedure, for example, message 3 (Msg3) or message A (MsgA), and the ID of the terminal is displayed so that the network knows.

[0125] Through the paging rejection message or the paging restriction message above, the network side determines that the terminal does not accept the first paging message corresponding to the AIoT service or restricts the network from sending the first paging message corresponding to the AIoT service to the terminal.

[0126] In the embodiment of the present application, if the UE is insufficient in current power or does not meet the UE reader condition or the paged AIoT device is not within the proximity of the UE, it is determined not to respond to the first paging message, and a paging rejection message or a paging restriction message is sent to inform the network side that the terminal does not respond to the first paging message, avoiding the network to continue invalid paging, thereby effectively saving the paging resource.

[0127] In the embodiment of the present application, the terminal acquires a first paging message, the first paging message is used for paging the terminal, wherein the terminal assists AIoT devices as an environmental Internet of Things (AIoT) reader-writer to perform AIoT communication; in a case where it is determined that the terminal can respond to the first paging message, an access network process is initiated or a network connection recovery process is initiated, thereby realizing paging of the terminal reader-writer, expanding the coverage range of the network, ensuring the communication success rate and time delay overhead performance, and thereby reducing the network complexity and network overhead on the basis of enhancing the transmission effect.

[0128] As shown in FIG. 5, the embodiment of the present application provides a paging method, which is executed by a first network side device, and the method comprises:

[0129] Step 501: sending a first paging message, the first paging message is used for paging a terminal, wherein the terminal assists AIoT devices as an AIoT reader-writer to perform AIoT communication.

[0130] In the embodiment of the present application, the first network side device sends a first paging message, the first paging message is used for paging a terminal, wherein the terminal assists AIoT devices as an AIoT reader-writer to perform AIoT communication. In this scheme, the terminal can enter a connected state based on the first paging message, and assists AIoT devices as an AIoT reader-writer to perform AIoT communication, that is, the terminal is a communication node of the network side device and the AIoT device for AIoT communication, and the paging of the AIoT device is realized through the terminal reader-writer, thereby expanding the coverage range of the network side device and avoiding the problem that the network side device cannot page the AIoT device due to limited coverage range.

[0131] Optionally, before sending the first paging message, it further comprises:

[0132] acquiring a second paging message sent by a second network side device, the second paging message is used for instructing the first network side device to page an AIoT reader-writer, and the AIoT reader-writer comprises the terminal.

[0133] The second network side device comprises a core network device, such as an Access and Mobility Management Function (AMF) or an AIoT special control entity, and the first network side device comprises a base station.

[0134] In the embodiments of the present application, after receiving the second paging message, the first network side device sends the first paging message to the terminal.

[0135] As an optional implementation, the second paging message includes:

[0136] terminal identifier of the at least one terminal;

[0137] AIoT related information.

[0138] In some embodiments of the present application, the at least one terminal identifier can be presented in the form of a list, i.e., the second paging message includes a terminal identifier list (UE ID list) and AIoT related information. Based on the terminal identifier list and the AIoT related information, the first network side device determines that the second network side device needs to page the terminal reader-assisted AIoT device for AIoT communication.

[0139] Optionally, the AIoT related information includes at least one of the following:

[0140] The first item: second indication information, the second indication information is used to indicate that the paging process corresponding to the second paging message is a paging process about AIoT reader, and the AIoT reader includes a terminal.

[0141] The second indication information can include 1 bit information, which indicates that this is a paging about AIoT UE reader. The second indication information can be indicated by paging cause (Paging Cause).

[0142] The second item: AIoT paging information.

[0143] Optionally, the AIoT paging information includes at least one of the following:

[0144] AIoT service type;

[0145] Indication information for initiating an inventory process or indication information for initiating a command process;

[0146] AIoT device scale information corresponding to the AIoT service; the AIoT device scale information includes device quantity, quantity level, etc.

[0147] Paging parameter; for example, the paging parameter includes paging range information, paging frequency information, paging number information, paging period information, paging accuracy information, paging time delay requirement information, etc.

[0148] AIoT interface parameter.

[0149] The third item: information of the AIoT device being paged.

[0150] In some embodiments of the present application, the information of the AIoT device being paged includes AIoT filtering information or a MASK.

[0151] Based on the information of the AIoT device being paged, the terminal reader / writer can determine whether the AIoT device being paged is in the communication range, so as to determine whether to respond to the paging.

[0152] Optionally, in the implementation, the first paging message includes:

[0153] The terminal identifier of the terminal being paged, which is the terminal identifier in the first paging message.

[0154] The first indication information, which is used to indicate that the terminal being paged is an AIoT reader / writer.

[0155] The first paging message includes the terminal identifier of at least one terminal being paged. For example, the first paging message includes a terminal identifier list.

[0156] In some embodiments of the present application, the terminal identifier of the terminal being paged is carried in the first paging message in the case that there is a certain association relationship between the terminal and the AIoT device. The association relationship can be pre-configured or exist in some specific scenarios. Through the first paging message, the first network side device can reuse the existing paging procedure of the base station to the terminal.

[0157] Optionally, in the implementation, the first paging message is sent, including:

[0158] The first paging message is sent at the first paging occasion, and the first paging occasion includes the paging occasion corresponding to the at least one terminal.

[0159] The at least one terminal is the terminal corresponding to the terminal identifier carried in the second paging message.

[0160] In the implementation, since it is paging for a specific terminal, the paging basic procedure can reuse the existing paging procedure.

[0161] As another optional implementation, the first paging message or the second paging message respectively includes at least one of the following:

[0162] The first item: a paging identifier, which is used to indicate to the terminal that the paging object is a terminal acting as an AIoT reader / writer.

[0163] Based on the paging identifier, the terminal determines that the base station needs to find a terminal-assisted AIoT device with terminal reader-writer capability for AIoT communication.

[0164] Secondly, group information of the terminal, which is group information when the terminal is an AIoT reader-writer.

[0165] For example, the terminal reader-writer can be grouped or managed in a core network process or a service layer process such as a registration process or a group management process, and the terminal reader-writer can belong to a specific group or serve a specific AIoT service or a specific AIoT device; that is, the above-mentioned group information is associated with a specific AIoT service or a specific AIoT device.

[0166] Thirdly, AIoT service information.

[0167] For example, the AIoT service information includes a service type, AIoT device information corresponding to the AIoT service, and the like.

[0168] Based on the AIoT service information, the terminal determines whether it can meet the requirement of providing the AIoT service, and further determines whether to respond to the first paging message.

[0169] Fourthly, information of the paged AIoT device.

[0170] For example, the information includes the number of AIoT devices, the location of the AIoT device, AIoT filtering information, or MASK information.

[0171] Based on the information of the paged AIoT device, the terminal determines whether the paged AIoT device is located in the proximity of the terminal, and further determines whether to respond to the first paging message.

[0172] In the embodiments of the present application, based on the content of the first paging message, the terminal determines that the base station needs to find a terminal-assisted AIoT device with terminal reader-writer capability for AIoT communication, and further determines whether the terminal responds to the first paging message.

[0173] Optionally, in the implementation manner, the first paging message is sent, including:

[0174] The first paging message is sent at a second paging occasion; the second paging occasion includes a paging occasion corresponding to all terminals served by the first network side device, or a paging occasion corresponding to a terminal with AIoT reader-writer capability among the terminals served by the first network side device, or a paging occasion corresponding to a terminal indicated by the second network side device.

[0175] The paging procedure of this implementation is different from the traditional paging procedure. The terminal identifier is not carried in the second paging message, and therefore, in order to find a UE with a specific attribute, such as an AIoT UE reader, extensive transmission is required to ensure that more UEs meeting the demand can receive it. By sending the first paging message at the second paging occasion, more UEs meeting the demand can receive the first paging message.

[0176] Optionally, in this implementation, the method further includes:

[0177] sending dedicated paging information;

[0178] The dedicated paging information includes at least one of the following:

[0179] a dedicated paging cycle, the dedicated paging cycle being a cycle of the first network side device paging an AIoT reader, the AIoT reader including a terminal;

[0180] a dedicated paging time domain pattern, the dedicated paging time domain pattern being used to indicate a time domain location parameter of the first network side device paging the AIoT reader;

[0181] a dedicated paging identifier, the dedicated paging identifier being a scheduling identifier of the first network side device paging the AIoT reader, for example, the scheduling identifier being a first paging radio network temporary identifier (P-RNTI) value, the first P-RNTI being used to scramble a PDCCH to schedule a dedicated paging;

[0182] a dedicated paging modulation and coding parameter, the dedicated paging modulation and coding parameter being a modulation and coding parameter of the first network side device paging the AIoT reader;

[0183] dedicated paging resource information, the dedicated paging resource information being resource information of the first network side device paging the AIoT reader.

[0184] In the embodiments of the present application, the dedicated paging information can be sent through a system information block (SIB) or dedicated signaling.

[0185] The paging information for the terminal reader is the dedicated paging information described above. By configuring the dedicated paging information, the terminal reader listens to the first paging information based on the dedicated paging information, and the non-terminal reader can ignore the dedicated paging information, avoiding unnecessary listening, thereby reducing the impact on the non-terminal reader and saving the energy consumption of the non-terminal reader.

[0186] Optionally, the method of the embodiments of the present application further comprises:

[0187] sending first condition information, the first condition information being used for the terminal to determine whether it can serve as an AIoT reader, the first condition information including at least one of the following:

[0188] The first item: Uu channel condition information, the Uu channel condition information being Uu channel condition information that needs to be met by the terminal to serve as an AIoT reader.

[0189] For example, the Uu channel condition information includes a reference signal received power (RSRP) threshold, which can be a minimum RSRP threshold. When the Uu link RSRP of the UE is lower than the threshold, it indicates that the UE has poor coverage and is thus not suitable to serve as a UE reader. The RSRP threshold can also be a maximum RSRP threshold. When the Uu link RSRP of the UE is higher than the threshold, it indicates that the UE is located in the center of the cell and has limited coverage. AIoT devices within the coverage radius of the UE can be directly served as readers by the gNB, so that transmission efficiency and latency performance can be effectively improved based on the RSRP.

[0190] The second item: AIoT interface condition information, the AIoT interface condition information being AIoT interface condition information that needs to be met by the terminal to serve as an AIoT reader.

[0191] For example, the AIoT interface condition information includes at least one of the following: a transmission power level of the AIoT interface, a receiving capability, a transmission capability, and a link quality threshold of the AIoT interface. For example, when there is a certain binding relationship between the UE reader and the AIoT device, the link quality threshold is too low in previous or last communication, and it is determined that the UE reader cannot perform communication assistance for the device.

[0192] In the embodiments of the present application, the terminal first determines whether the conditions for serving as an AIoT reader are met based on the first condition information. If the conditions for serving as an AIoT reader are met, the terminal then determines whether to respond to the first paging message according to its own conditions such as power. If it is determined to respond to the first paging message, the terminal initiates an initial access process or a network connection recovery process to the network and enters a connected state. If the first condition information is not met, the terminal notifies the network to avoid wasting paging resources.

[0193] Optionally, the method of the embodiments of the present application further comprises:

[0194] sending access information, the access information including network access information when the terminal serves as an AIoT reader.

[0195] In the embodiments of the present application, a terminal reader-writer is configured with special access information, for example, the access information includes access level, access parameter, etc., if no special access information is configured, the UE uses default access information, for example, similar to the access parameter of downlink data arrival. Through the access information, the terminal reader-writer can enter the connected state, and then assist the AIoT device to perform AIoT communication.

[0196] As shown in FIG. 6, the embodiments of the present application provide a paging method, executed by a second network side device, the method comprising:

[0197] Step 601: sending a second paging message, the second paging message being used to instruct a first network side device to page an AIoT reader-writer, the AIoT reader-writer comprising a terminal.

[0198] The second network side device comprises a core network device, such as an AMF or an AIoT special control entity.

[0199] In the embodiments of the present application, the second network side device sends a second paging message to the first network side device, the second paging message being used to instruct the first network side device to page an AIoT reader-writer, the AIoT reader-writer comprising a terminal, so that the second network side device sends a first paging message according to the second paging message, the first paging message being used to page the terminal, wherein the terminal assists an AIoT device to perform AIoT communication as an AIoT reader-writer, so that the terminal can enter a connected state based on the first paging message and assist the AIoT device to perform AIoT communication as an AIoT reader-writer, that is, the terminal is a communication node of the AIoT of the network side device and the AIoT device, and the terminal reader-writer is used to realize paging of the AIoT device, thereby expanding the coverage range of the network side device and avoiding the problem that the network side device cannot page the AIoT device due to limited coverage range.

[0200] Optionally, the second paging message comprises:

[0201] terminal identifier of at least one terminal;

[0202] AIoT related information.

[0203] Optionally, the AIoT related information comprises at least one of the following:

[0204] second indication information, the second indication information being used to indicate that a paging process corresponding to the second paging message is a paging process about an AIoT reader-writer, and the AIoT reader-writer comprises a terminal;

[0205] AIoT paging information;

[0206] Information of the AIoT device being paged.

[0207] Optionally, the AIoT paging information includes at least one of the following:

[0208] An AIoT service type;

[0209] Indication information for initiating an inventory process or indication information for initiating a command process;

[0210] AIoT device scale information corresponding to the AIoT service;

[0211] Paging parameters;

[0212] AIoT interface parameters.

[0213] Optionally, the second paging message includes at least one of the following:

[0214] A paging identifier, the paging identifier being used to indicate a terminal as an AIoT reader as a paging object;

[0215] Group information of the terminal, the group information being group information of the terminal as an AIoT reader;

[0216] AIoT service information;

[0217] Information of the AIoT device being paged.

[0218] The second paging message has been described in detail in the above description, and will not be described here again.

[0219] In the embodiment of the application, the second network side device sends a second paging message to the first network side device, the second paging message being used to instruct the first network side device to page an AIoT reader, the AIoT reader including a terminal, so that the second network side device sends a first paging message according to the second paging message, the first paging message being used to page the terminal, wherein the terminal as an AIoT reader assists an AIoT device to perform AIoT communication, thereby achieving paging of the terminal reader, expanding the coverage of the network, and ensuring the communication success rate and the time delay overhead performance, so as to reduce the network complexity and the network overhead on the basis of enhancing the transmission effect.

[0220] The paging method of the application will be described in detail below in combination with embodiments.

[0221] Embodiment one:

[0222] This embodiment describes the overall framework of the AIoT Uu paging scheme carrying a UE ID, the corresponding behaviors of the UE and the network side, and the like.

[0223] In a typical scenario, for example, factory deployment, or in a relatively stable / fixed range, there can be a certain semi-static association between UE and device, which can be accumulated by pre-configuration or a certain period of trial and observation in the core network. In summary, when the core network is preparing to initiate paging or service request to the device, according to the pre-configuration or the record of its own algorithm, it is found that the device or these devices need to use Topo2 for AIoT communication through a specific UE reader. The core network can choose to send a paging to the specific UE first, wake up the UE to the connected state, and then issue an AIoT service request, so as to carry out subsequent AIoT communication. Of course, if these UEs are already in the connected state, the AIoT service request can be directly issued. The embodiment focuses on the case of the UE reader in the IDLE state.

[0224] In the case that the core network knows the alternative UE reader ID, a more efficient way is that the core network initiates a paging process carrying the UE ID through the NG interface to the list of possible serving base stations of the UE. Among them, the list of possible serving base stations of the UE can be determined by reusing the existing scheme, for example, according to the latest tracking area (Tracking Area, TA) list of the UE, the last serving base station and the surrounding situation, the mobile trajectory prediction and other information. The embodiment focuses on the enhancement of the paging content carrying the UE ID. First, the AIoT related information is added in the paging content (carried by the second paging message) sent by the core network to the gNB in the NG interface. The AIoT related information includes at least one of the following:

[0225] A1: AIoT UE reader paging indication, i.e., the second indication information described above;

[0226] The AIoT UE reader paging indication can be 1 bit content, which is used to indicate that this is a paging process about AIoT UE reader. Alternatively, the AIoT UE reader paging indication can be indicated by the paging cause.

[0227] A2: AIoT paging information.

[0228] The AIoT paging information has been described in the above description, which will not be repeated here;

[0229] A3: AIoT device information being paged.

[0230] The more detailed the paging content information is, the greater the system overhead is, and it will be sent in multiple cells, thereby causing the overhead to grow exponentially, but it is beneficial for the UE reader to make accurate judgments. If less information is carried, although it is beneficial to system overhead, the information is lacking, and after the UE arrives in the connected state as downlink data, it is found that it cannot be released as a UE reader, which will also waste signaling overhead for state transition. Therefore, adding a small amount of necessary indication, such as 1 bit of AIoT UE reader paging indication, can be used as a compromise solution.

[0231] In this scheme, since it is a paging for a specific UE, the paging basic flow can reuse the existing paging flow, such as the calculation of the paging occasion (PO) of the UE, the range of the cell sending the UE paging, etc. The main difference between this paging flow and the existing paging is that in the NG signaling sent by the AMF to the gNB, in addition to the traditional paging information and UE ID information, AIoT related information is also added, and although the NG signaling may also be sent to multiple gNBs, since the NG signaling is generally wired transmission, it is not sensitive to overhead, so the enhanced AIoT related information in the NG signaling can carry more information, for example, carry the contents of the above A2 and A3. While the air interface sent paging message, such as the above first paging message, since it occupies the air interface resource, the AIoT related information can be simplified as much as possible, for example, only introduce 1 bit of AIoT reader / relay indication, which can also be described as the above paging identifier, indicating that this paging is to hope that the UE enters the connected state as a UE reader to assist AIoT communication.

[0232] For the UE, without changing the existing location and way of listening to the paging message, the UE reads the paging message at its own PO location, and if it finds its own UE ID and AIoT related information, it can know that this is the network side hoping that it enters the connected state as a UE reader to assist in completing the AIoT communication task. The UE can then determine whether to respond to the network side paging according to its own situation, and initiate access to enter the connected state process when it determines to respond to the network side paging. If the UE does not meet the UE reader condition due to insufficient current or the AIoT device being paged is not in the proximity of the UE, the UE can refuse to respond to the network side paging. But the UE can tell the network that the UE cannot respond to the paging to avoid the network continuing to waste resources for useless paging.

[0233] Optionally, the informing manner can be sending a paging rejection message or a paging restriction message, which is used to indicate to the network that the UE does not accept the paging message of the AIOT service or restricts the network from sending the paging message of the AIOT service to the UE. For example, the paging rejection message is carried in a service request message through a NAS process, or the paging rejection message is sent in a RACH process, such as Msg3 or MsgA, and the ID of the UE is displayed so that the network knows.

[0234] In particular, the network side can send some condition information (i.e., the first condition information described above) and / or special access information of the UE reader to the UE reader through a SIB message or dedicated signaling.

[0235] The first condition information and the access information are described in detail in the above description, which will not be repeated here.

[0236] In this way, since the gNB has a specific UE ID when paging, after the UE enters the connected state in response to the paging, it does not need to report any information, and the network side knows that it is for assisting AIoT communication as a UE reader. Therefore, the base station can further send the AIoT service request and other detailed information that cannot be carried by the paging to the UE through RRC dedicated signaling or NAS signaling, so as to facilitate the UE to page the device through the AIoT interface and perform subsequent communication.

[0237] In this embodiment, when the UE ID list is carried in the second paging message sent by the CN to the gNB, the gNB initiates a UE-related paging process on the Uu interface and sends a first paging message at the PO position of a specific UE. In particular, the first paging message carries the first indication information described above. When the UE receives the paging of its own UE ID, it can determine whether to respond to the paging according to the first indication information, for example, whether to meet the condition, whether to have power, whether to have processing margin, etc. If it can respond, it initiates an initial access process to the network and accesses according to the configured or default access parameters to enter the connected state. If it cannot become a UE reader, it needs to notify the network to avoid wasting paging resources.

[0238] Embodiment two:

[0239] This embodiment describes the overall framework of the AIoT Uu paging scheme without UE ID, the corresponding behaviors of the UE and the network side, etc.

[0240] In some scenarios, when the network side wants to find available UEs around the device as UE readers, i.e., there is no binding or prior association information between the UE readers and the device, and both types of devices are free to move in the network, this case will be more common and more universal.

[0241] When the network side cannot predict which UE around the AIoT device can be used as an intermediate node to assist AIoT communication, the network side can only perform paging in a more extensive manner to find a suitable UE reader.

[0242] First, the network side decides to page or request some AIoT devices according to the requirements of the AIoT scenario, such as initiating an inventory or command process. The core network control node, such as AMF or AIoT dedicated control entity, needs to have some basic prediction of the location of the AIoT device being paged or requested, such as through the record of the last business process, and / or device positioning information collection, and / or device movement trajectory judgment, etc. The control node sends the paging or business request of the AIoT device to a certain range of base stations, and at the same time carries a display indication allowing or tending UE readers to participate in assisted communication, such as the paging identifier in the second paging message above.

[0243] Next, for the base station, receiving the paging or business request of the AIoT device and the paging identifier carrying the indication allowing or tending UE readers to participate in assisted communication, if the base station itself has AIoT reader function, it can first perform the paging process for the device on the AIoT interface, if some required devices can be found, but not all, or the base station does not have AIoT reader function, or based on some prior information of coverage, it needs to find some UE readers to assist AIoT communication, then the base station can also initiate AIoT paging process for UE readers on the Uu interface.

[0244] This AIoT paging procedure is different from the traditional paging, which does not specify the UE ID, but finds the UE with specific attributes, such as the UE with AIoT UE reader capability. After the authorization and authentication of the UE reader, the UE that meets certain conditions can become the desired device for AIoT communication assisted by the UE reader. This communication process is equivalent to a group paging that meets certain conditions. Since the targeted UE is not specified, this AIoT UE reader paging needs to be widely sent to strive for more UE that meets the demand to receive the AIoT UE reader paging. The sending of the AIoT UE reader paging includes at least the following ways:

[0245] Way 1: AIoT UE reader paging needs to be sent in all possible PO positions of all UEs, i.e. the sending of the first paging message, so that more UEs can receive it;

[0246] Further, AIoT UE reader paging is only sent in the PO of the UE that can be a UE reader. This PO can be a PO defined for the UE reader.

[0247] Way 2: If the CN can provide information of some registered or authorized or authenticated UE readers, and has a rough estimate of the location of these UEs, such as in the vicinity of the paged device, the UE reader identifier list can be carried in the NG interface to assist the base station in deciding the PO position for sending the AIoT UE reader paging.

[0248] In this embodiment, a new cycle and paging method can also be designed, such as broadcasting the above-mentioned special paging cycle, special paging time domain pattern, special RNTI, special modulation and coding parameters, and special paging resources in the SIB. The UE reader with corresponding capability and authorization and authentication can listen to the special paging cycle in the case of permission to find the possible UE reader paging. This way can reduce the impact on ordinary UEs.

[0249] In this embodiment, the content of the AIoT UE reader paging is different from the traditional paging, which does not contain the UE ID, and can contain at least one of the following:

[0250] B1: AIoT UE reader paging identifier, i.e. the above-mentioned paging identifier, which means that the base station needs to find the UE with UE reader capability for AIoT assisted communication;

[0251] B2: group information of the UE reader, for example, the UE reader can be grouped or managed in a core network procedure or a service layer procedure such as a registration procedure or a group management procedure, and the UE reader can belong to a specific group and serve a specific AIoT service or a specific device;

[0252] B3: AIoT service information, which is used to indicate some specific information of the AIoT service, such as a service type and device information;

[0253] The more detailed information carried in the paging message, the greater the system overhead, and the paging message will be sent in multiple cells, thereby causing the overhead to grow exponentially, but it is beneficial for the UE reader to make accurate judgments. If only a small amount of indication information is carried, although it is beneficial to the system overhead, the information is lacking, and after the UE enters the connected state as the downlink data arrives, it is found that it cannot be released as a UE reader, which will also waste the signaling overhead of state transition. Therefore, information and overhead need to be compromised, for example, the B1 item and the B2 item can be carried in the first paging message, which can be a compromise solution.

[0254] For the UE, it can listen to the normal PO position of itself or an additional AIoT UE reader dedicated paging position, and if it finds a paging related to the UE reader and the UE has relevant capabilities and has obtained authorization and authentication, it can be understood that this is the network side hoping that the UE enters the connected state to assist the completion of the AIoT communication task as a UE reader. The UE can judge whether to respond to the network side paging and initiate access to enter the connected state according to its own situation. If the UE does not meet the UE reader condition due to insufficient current power or other reasons, it can avoid responding.

[0255] In particular, the network side can send some condition information (i.e., the first condition information described above) and / or special access information about the UE reader to the UE reader through SIB messages or dedicated signaling.

[0256] The first condition information and access information are described in detail above and will not be repeated here.

[0257] In this way, since the gNB does not have a specific target UE ID when paging, after the UE enters the connected state in response to the paging, the UE needs to report information to let the network side know that it enters the connected state for the purpose of assisting AIoT communication as a UE reader, for example, in Msg3 (RRC establishment request message) or Msg5 (RRC establishment completion message), or in a special reporting signaling later, report the identity or purpose of the UE reader, and then the base station can further send the AIoT business request details that cannot be carried by the paging to the UE through RRC dedicated signaling or NAS signaling, so that the UE can page the device through the AIoT interface and perform subsequent communication.

[0258] In the embodiments of the present application, when there is no UE ID information in the AIoT related paging message sent by the CN to the gNB, the CN can indicate that this is an AIoT paging process supporting the UE reader, the gNB sends the AIoT related paging process on the Uu interface, and sends it at all UE PO positions, carrying the AIoT related paging content; in particular, the gNB can broadcast condition information about AIoT paging in the SIB message, such as meeting certain Uu RSRP threshold, meeting certain AIoT communication conditions, access parameters when the AIoT reader accesses, etc.; when the UE receives the AIoT related paging, it can judge whether to respond to the paging according to the AIoT paging content, for example, whether it has the relevant capability and authorization, whether it meets the conditions, if it can respond, it initiates an initial access process to the network, and accesses according to the configured or default access parameters, enters the connected state, and displays to the network that the reason for entering the connected state is to respond to the AIoT paging or because of the UE reader.

[0259] Based on the above two embodiments, some network side deployment implementations and coexistence considerations are given below.

[0260] For the network side, multiplexing or enhancing the traditional paging process carrying the UE ID is a relatively simple way, especially completely multiplexing the traditional paging, which can be directly based on network implementation. However, even if the air interface paging can multiplex the existing process, due to the difference between the subsequent AIoT UE reader process and the arrival of existing paging downlink data, the difference between the L2 and L3 architectures of the UE reader, the NG interface, the NAS interface process and / or the new RRC process, may all be needed. Therefore, the base station needs to enhance the AIoT UE reader, and the UE needs to be enhanced to be a UE reader. From this point of view, enhancing the air interface paging to carry the necessary indication information of the AIoT UE reader is not relatively smooth.

[0261] Since the traditional paging or enhanced method is only applicable to the case where the network side has good prior information about the binding relationship or location relationship of the UE reader and the device, in the case where the UE reader and the device belong to public devices and are free to move, in order to obtain and maintain the above prior information, the network side also needs to pay a large cost and overhead. Therefore, the more widely used method is to allow the UE reader and the device to be independent of each other, and to use a dedicated paging to find the UE reader that may be around the device for auxiliary communication, that is, the paging process without setting the UE ID.

[0262] The two types of paging processes can coexist, and the network side decides which paging process to take according to different scenarios and different devices.

[0263] In the above scheme of the embodiments of the present application, the network can find a suitable UE reader through the enhanced Uu interface paging process to perform AIoT auxiliary communication, expand the network coverage, ensure the communication success rate and time delay overhead performance, and ensure the network complexity and overhead on the basis of enhancing the transmission effect.
