[0086] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0087] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0088] The technical solutions provided in this disclosure can be applied to various systems, such as 5G systems. This disclosure provides a paging method. The technical solutions in this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0089] The A-IoT device involved in this disclosure is a passive or limited energy storage A-IoT device, which can be referred to as a device. It can transmit uplink information through downlink signals emitted by a reflection network or a reading device or wireless signals in the environment. It can interact with the core network through a reading device (reader).

[0090] The reader involved in this disclosure can be a network device, specifically a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with wireless A-IoT devices via one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless A-IoT devices and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in this disclosure can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA) system, a NodeB in a wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in this disclosure. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0091] For example, in embodiments of this disclosure, network devices and A-IoT devices can each use one or more antennas to perform multi-input multi-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0092] The reading device involved in the embodiments of this disclosure can also be an intermediate node, which can be a relay node, an Integrated Access and Backhaul (IAB) node in the network, a User Equipment (UE), etc. The intermediate node transmits data and signaling between network devices and A-IoT devices. The UE can be a device that provides voice and / or data connectivity to users, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem, etc. The name of the terminal may also be different in different systems. For example, in a 5G system, the terminal can be called User Equipment (UE). Wireless A-IoT devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless A-IoT devices can be mobile A-IoT devices, such as mobile phones (or "cellular" phones) and computers with mobile A-IoT devices. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless A-IoT devices can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote A-IoT devices, access A-IoT devices, user A-IoT devices, user agents, and user devices; however, this disclosure does not limit the scope of the examples.

[0093] The technical solutions provided in this disclosure include two topologies for A-IoT device access networks: Topology 1 and Topology 2.

[0094] Topology 1 can be seen in Figure 1, which is a schematic diagram of the topology of an A-IoT device accessing a network provided by an embodiment of this disclosure. In this diagram, the base station acts as a reader, and the A-IoT device directly communicates / connects with the base station to perform signaling or data transmission.

[0095] Topology 2, as shown in Figure 2, is another topology diagram of A-IoT device accessing the network provided in this embodiment of the present disclosure. In this topology, the intermediate node acts as a reader. The A-IoT device does not communicate / connect directly with the network, but connects to the intermediate node and then connects to the network through the intermediate node.

[0096] In A-IoT device paging scenarios, services include inventory, command, sensor, and positioning. The inventory service is used to confirm whether an A-IoT device is within range. When a core network element or reader sends an inventory message to the device, the device can respond with its identifier. The command service instructs the device to perform corresponding operations when a core network element or reader sends a command to the device. Examples include read, write, and deactivate commands. The device can then execute these operations. During A-IoT device paging, in scenarios with security requirements, paging messages need to be transmitted securely.

[0097] Figure 3 is a flowchart illustrating a paging method provided in an embodiment of this disclosure, applied to an A-IoT device. Referring to Figure 3, the method may include:

[0098] S301, Receive the first message sent by the reading device. The first message is used to page the target A-IoT device.

[0099] The first message carries first instruction information, which adopts at least one of the following formats:

[0100] It is contained within the target layer container, and the indication information is a plaintext information element (cleartext IE);

[0101] Contained within the target layer container, and the indication information is a non-cleartext element (IE);

[0102] The information indicates that it is an Information Element (IE) of the Access Stratum (AS).

[0103] The target layer refers to the peer layer between core network elements and A-IoT devices. The target layer can be the upper layer of the AS layer, such as the Non-Access Stratum (NAS) layer or other newly defined layers, such as the A-IoT NAS layer or the application layer. The specific configuration can be determined according to actual needs. Taking the A-IoT NAS layer as an example, the corresponding target container can be denoted as the A-IoT NAS container.

[0104] Plaintext information elements refer to information elements that have not been encrypted by the target layer and whose integrity is protected; non-plaintext information elements refer to information elements that have been encrypted by the target layer and whose integrity is protected.

[0105] For example, the access layer can be the Medium Access Control (MAC) layer, the Radio Resource Control (RRC) layer, or other AS layers, which can be configured according to actual needs.

[0106] As can be seen, in this embodiment of the disclosure, the A-IoT device receives a first message sent by the reading device. The first message is used to page the target A-IoT device. The first message carries first indication information, which adopts at least one of the following formats: contained in a target layer container and the indication information is a plaintext information element; contained in a target layer container and the indication information is a non-plaintext information element; or the indication information is an information element of the access layer. By transmitting the first indication information using this at least one format, the security of the first message transmission can be effectively guaranteed, thereby effectively solving the problem of how to achieve secure transmission of paging messages during the paging process of the A-IoT device.

[0107] Based on the embodiment shown in Figure 3 above, for example, in this embodiment of the disclosure, the first indication information includes at least one of the following:

[0108] First safety type indication;

[0109] Key identifier;

[0110] First integrity protection parameter;

[0111] First key parameters;

[0112] Identification of the target A-IoT device;

[0113] Order.

[0114] For example, in embodiments of this disclosure, the first instruction information may include, in addition to at least one of the above, at least one of the following:

[0115] Message type;

[0116] Message identifier;

[0117] Random access parameters.

[0118] Among them, the message type can be used to indicate what business the first message is used for or to indicate the information contained in the message, such as indicating inventory business, command business, location business, sensing business, etc.; the message identifier is used to identify a business process, such as indicating an inventory business process or a command business process; the first security type indicator is used to indicate the security protection type of the first message, specifically, it can indicate whether the first message has been protected for integrity, encrypted, etc.; the key identifier is used to indicate the identifier of the target A-IoT device being paged by the reading device, and the A-IoT device can determine whether the target A-IoT device of the first message is itself based on the key identifier; the first integrity protection parameter is used by the A-IoT device to perform integrity verification; the first key parameter is used by the A-IoT device to perform decryption; and the random access parameter is used by the A-IoT device to initiate random access.

[0119] For example, in this embodiment of the disclosure, the first security type indicator is used to indicate whether encryption and integrity protection are performed, including the following indication methods: one method is that the first security type indicator can indicate that the first message is encrypted, and the first indication information also includes a first key parameter; another method is that the first security type indicator can indicate that the first message is protected for integrity, and the first indication information also includes a first integrity protection parameter; yet another method is that the first security type indicator can indicate that the first message is encrypted and protected for integrity, and the first indication information also includes a first key parameter and a first integrity protection parameter; and yet another method is that the first security type indicator can indicate that the first message is not encrypted and protected for integrity.

[0120] For example, in this embodiment of the disclosure, the key identifier can be the identifier (ID) of the target device, the Electronic Product Code (EPC) ID, a temporary identifier, a group ID, or an indication that instructs all A-IoT devices to respond, etc. It can be the complete identifier or a part of the above identifiers, and can be set according to actual needs.

[0121] For example, in this embodiment of the disclosure, the first integrity protection parameter can be a security protection parameter, which can be a security protection verification code. The A-IoT device calculates an integrity verification code based on an integrity algorithm. If the calculated integrity verification code matches the security protection verification code in the first message, then the received first message and the sent first message are considered to be consistent, that is, the received first message has not been tampered with.

[0122] For example, in this embodiment of the disclosure, the first key parameter can be a random number, key, password, etc., and can be set according to actual needs.

[0123] For example, in an embodiment of this disclosure, receiving a first message sent by the reading device may include:

[0124] The first message is received through the access layer of the A-IoT device; or...

[0125] The first instruction information in the first message received by the A-IoT device is forwarded to the target layer of the A-IoT device through the access layer, thereby achieving secure reception of the first message.

[0126] For example, in this embodiment of the disclosure, the access layer of the A-IoT device can forward all of the first indication information to the target layer of the A-IoT device, or it can forward part of the information in the first indication information to the target layer of the A-IoT device. For example, the access layer forwards the target layer container to the target layer. The specific settings can be configured according to actual needs.

[0127] For example, in this embodiment of the disclosure, when the first indication information includes a key identifier, the A-IoT device can also determine whether the key identifier matches the identifier of the A-IoT device; and if the key identifier matches the identifier of the A-IoT device, it can parse other information in the first indication information, such as parsing the target layer container.

[0128] For example, in this embodiment of the disclosure, when the first indication information includes message type, message identifier, first security type indication, key identifier, first integrity protection parameter, first key parameter, identifier of the target A-IoT device, command, and random access parameter, other information may include message type, message identifier, first security type indication, first integrity protection parameter, first key parameter, and command and random access parameter; when the first indication information includes message type, key identifier, first integrity protection parameter, first key parameter, and identifier of the target A-IoT device, other information may be message type, first integrity protection parameter, and first key parameter, which can be set according to actual needs.

[0129] For example, in this embodiment of the disclosure, after receiving the first message sent by the reading device, the A-IoT device may also send a first response message to the reading device, the first response message including second indication information;

[0130] The second instruction information includes at least one of the following:

[0131] Second safety type indication;

[0132] Second integrity protection parameter;

[0133] Second key parameter;

[0134] Identification of A-IoT devices;

[0135] Command response;

[0136] Message identifier.

[0137] For example, in this embodiment of the disclosure, the second instruction information may also take at least one of the following formats:

[0138] It is contained within the target layer container, and the indication information is a plaintext information element;

[0139] It is contained within the target layer container, and the indication information is a non-plaintext information element;

[0140] The indication information is an information element of the access layer.

[0141] It is understood that the format of the second instruction information is similar to that of the first instruction information described above, and will not be repeated here in this embodiment of the present disclosure.

[0142] For example, in this embodiment of the disclosure, sending a first response message to the reading device may include:

[0143] The target layer of the A-IoT device instructs the access layer of the A-IoT device to send a first response message to the reading device; or...

[0144] The access layer of A-IoT devices initiates random access based on random access parameters. Random access is used to send the first response message, thereby enabling the sending of the first response message.

[0145] To facilitate understanding of the paging method provided in the embodiments of this disclosure, the paging method provided in the embodiments of this disclosure will be described in detail below through specific embodiments. In the following embodiments, device refers to A-IoT device and reader refers to reading device.

[0146] Example 1

[0147] In Example 1, if the first indication information includes a target device identifier, the paging method may include:

[0148] Step 1: The device receives the first message sent by the reader. The first message contains first indication information, which includes the target device identifier.

[0149] For example, in this embodiment of the disclosure, the target device identifier may indicate an identifier of a device or a group identifier, etc., and can be set according to actual needs.

[0150] Step 2: Based on the received target device identifier, the device performs a first response judgment. If it determines that a response is needed, it sends a first response message to the reader.

[0151] For example, in this embodiment of the disclosure, when the device performs the first response judgment, it can determine whether the target device identifier in the first message matches its own device identifier. If they match, the device determines to respond.

[0152] For example, in this embodiment of the disclosure, when the device sends a first response message to the reader, it can send a device identifier to the core network through the target layer.

[0153] For example, in Embodiment 1, if the first instruction information also includes a command, the first response message sent by the device to the reader may also include a response to the command. Specifically:

[0154] If the command is a read command, the response to the command is the information related to the command stored by the device. The device sends the information related to the command to the core network in the first response message in the format of the target layer container.

[0155] If the command is a write command, the response to the command is ACK, indicating whether the write was successful. The device sends this information to the core network in the first response message, carrying it in the format of the target layer container.

[0156] For example, in Embodiment 1, if the first information also includes random access parameters, the device can perform random access based on these parameters and send a first response message to the reader. For example, the random access parameters may include configurations such as time slots, frequency points, and frequency offsets that indicate device access; these can be set according to actual needs.

[0157] For example, in the above embodiment 1, the first message may take one of the following forms:

[0158] Form 1: The first message includes random access parameters, target device identifier, and command. The random access parameters are information elements of the A-IoT AS layer. The target device identifier and command are both contained in the target layer container and are plaintext information elements.

[0159] Form 2: The first message includes random access parameters, target device identifier, and command. The random access parameters are information elements of the A-IoT AS layer, and the target device identifier and command are contained in the target layer container and are non-plaintext information elements.

[0160] Form 3: The first message includes random access parameters, target device identifier, and command. The random access parameters are information elements of the A-IoT AS layer. The target device identifier is contained in the target layer container and is a plaintext information element. The command is contained in the target layer container and is a non-plaintext information element.

[0161] Form 4: The first message includes random access parameters, target device identifier, and command. The random access parameters, target device identifier, and command are all information elements of the A-IoT AS layer.

[0162] Based on the different forms of the first message mentioned above, in step 1 above, when the device receives the first message sent by the reader, it can include the following two cases:

[0163] When the structure of the first message is of form 1, form 2 or form 3 as described above, after the device receives the first message sent by the reader, it can forward the target layer container contained in the first message to the target layer of the device.

[0164] When the structure of the first message is of form 4, after the device receives the first message sent by the reader, it can parse the various information elements of the first message through its AS.

[0165] Furthermore, based on the different forms of the first message mentioned above, step 2 above, in which the device performs the first response judgment, can include the following two cases:

[0166] When the structure of the first message is in form 1, form 2 or form 3 as described above, the first response determination can be performed by the target layer of the device; if it is determined to respond, the target layer generates the first response message and submits it to the A-IoT AS layer, triggering the A-IoT AS layer to initiate random access.

[0167] When the structure of the first message is of form 4, the first response determination can be performed by the device's A-IoT AS layer; if it is determined to respond, the A-IoT AS layer generates the first response message and initiates random access.

[0168] Example 2

[0169] In Embodiment 2, if the first indication information includes a key identifier, a first security type indication, a first integrity protection parameter, and a first key parameter, then the paging method may include:

[0170] Step 1: The device receives the first message sent by the reader. The first message contains first indication information, which includes a key identifier.

[0171] For example, in this embodiment of the disclosure, the key identifier can be a device identifier. The device can determine whether the target layer container in the first message is sent to itself based on the key identifier. If the key identifier is the same as the device identifier, or if the key identifier is the same as part of the device identifier, it means that the key identifier matches the device identifier, that is, the key identifier is the same as the device identifier. Then the device parses the target layer container in the first message.

[0172] Step 2: Based on the received key identifier, the device performs a first response judgment. If the key identifier matches the device identifier, the device performs integrity and security verification on the first message and determines whether to respond according to business requirements. If the device determines to respond, it can perform random access based on the random access parameters in the first message and send a first response message to the reader.

[0173] It is understood that in this embodiment of the disclosure, when the device determines whether to respond based on business requirements, the first message may also include a target device identifier or a command. The device then generates a corresponding first response message to respond, as described in the relevant description in Embodiment 1 above. Here, this embodiment of the disclosure will not repeat the description.

[0174] For example, in Embodiment 2, if the first indication information further includes one or more of the following: a first security type indication, a first integrity protection parameter, and a first key parameter, the device can perform one or more of the following:

[0175] If the first indication information also includes a first security type indication, the device can parse the first message according to the first security type indication. Specifically, parsing the first message can be parsing the target layer container or other format information blocks in the first message that are protected by security.

[0176] If the first instruction information also includes the first integrity protection parameter, the device can calculate the integrity check code based on the integrity algorithm. If the calculated integrity check code is the same as the integrity protection code in the first message, then the received first message and the sent first message are considered to be consistent, that is, the received first message has not been tampered with.

[0177] If the first instruction information also includes a first key parameter, the device can calculate and obtain the key based on the first key parameter and parse the first message. Specifically, it can parse the target layer container or other format information blocks for security protection contained in the first message.

[0178] For example, in the above embodiment 2, the first message includes one or more of the following: random access parameters, key identifier, first security type indicator, first integrity protection parameters, and first key parameters. If the parameters appear, the first message can take one of the following forms:

[0179] Form 1: The random access parameters are information elements of the A-IoT AS layer. The key identifier, the first security type indicator, the first integrity protection parameter, and the first key parameter are all contained in the target layer container and are plaintext information elements.

[0180] Form 2, the random access parameters, key identifier, first security type indicator, first integrity protection parameters, and first key parameters are all information elements of the A-IoT AS layer. In this case, the first message also contains a target layer container, such as a command.

[0181] Form 3, random access parameters and key identifier are all information elements of the A-IoT AS layer, the first security type indicator, the first integrity protection parameter and the first key parameter are all contained in the target layer container and are plaintext information elements.

[0182] Based on the different forms of the first message mentioned above, in step 1 above, when the device receives the first message sent by the reader, it can include the following two cases:

[0183] When the structure of the first message is as described in Form 1 above, after receiving the first message sent by the reader, the device can forward the target layer container contained in the first message to the target layer of the device. The target layer of the device determines whether the key identifier matches the device identifier of the device. If the key identifier matches the device identifier of the device, the target layer container is parsed. Conversely, if the key identifier does not match the device identifier of the device, the target layer container is not parsed.

[0184] When the structure of the first message is of form 2, after the device receives the first message sent by the reader, it can determine whether the key identifier matches the device identifier through its A-IoT AS layer. If the key identifier matches the device identifier, it forwards the first security type indication, the first integrity protection parameter and the first key parameter to the target layer, which performs integrity verification and security verification and parses the target layer container.

[0185] When the structure of the first message is of form 3, after the device receives the first message sent by the reader, it can determine whether the key identifier matches the device identifier of the device through its A-IoT AS layer. If the key identifier matches the device identifier of the device, the target layer container contained in the first message is forwarded to the target layer of the device, and the target layer performs integrity verification and security verification, and parses the target layer container.

[0186] Furthermore, based on the different forms of the first message mentioned above, step 2 above, in which the device performs the first response judgment, may include:

[0187] When the structure of the first message is in form 1, form 2 or form 3 as described above, the first response determination can be performed by the target layer of the device; if it is determined to respond, the A-IoT NAS layer generates the first response message and submits it to the A-IoT AS layer, triggering the A-IoT AS layer to initiate random access.

[0188] Example 3

[0189] In embodiment 3, if the first indication information includes a first security type indication, a first integrity protection parameter, and a first key parameter, then the paging method may include:

[0190] Step 1: The device receives the first message sent by the reader. This first message contains first indication information, which includes a first security type indication and the target layer container. The first security type indication can indicate one of the following security protection types:

[0191] Type 1: Integrity protection only. In this type, the first indication information also includes the first integrity protection parameter.

[0192] Type 2: Encryption only. In this type, the first indication information also includes the first key parameter.

[0193] Type 3: Integrity protection and encryption are performed. In this type, the first indication information also includes the first integrity protection parameter and the first key parameter.

[0194] Type 4: No integrity protection and no encryption

[0195] Step 2: Based on the received first security type indication, the device determines the security protection type of the first message. It then performs corresponding security protection processing for different types, for example:

[0196] If the security protection type is Type 1, the device performs integrity verification. For example, the device can calculate an integrity checksum based on an integrity algorithm. If the calculated integrity checksum is the same as the integrity protection code in the first message, then the received first message is considered to be consistent with the sent first message, meaning the received first message has not been tampered with.

[0197] If the security protection type is type 2, the device will decrypt. For example, the device can calculate the key based on the first key parameter and parse the first message. Specifically, it can parse the target layer container or other formatted information blocks protected by security contained in the first message.

[0198] If the security protection type is type 3, the device performs integrity verification and decryption. Refer to the operations for security protection types 1 and 2.

[0199] If the security protection type is type 4, then the device does not need to perform security protection related operations;

[0200] The object of the security protection processing performed by the Device is the first message, which may specifically be the target layer container contained in the first message.

[0201] In this embodiment, the target layer container may contain a target device identifier and / or command. The device determines whether to respond based on the device identifier and / or command.

[0202] In this embodiment, the first message may also include random access parameters. If the device determines to respond, the device can perform random access based on the random access parameters in the first message and send a first response message to the reader.

[0203] For example, in the above embodiment 3, the first message includes one or more of the following: random access parameters, a first security type indication, a first integrity protection parameter, and a first key parameter. If the parameter appears, the first message can take one of the following forms:

[0204] Form 1: The random access parameter is an information element of the A-IoT AS layer. The first security type indicator, the first integrity protection parameter, and the first key parameter are all contained in the target layer container and are plaintext information elements.

[0205] Form 2, the random access parameters, the first security type indication, the first integrity protection parameters, and the first key parameters are all information elements of the A-IoT AS layer. In this case, the first message also contains a target layer container, such as containing a target device identifier and / or a command.

[0206] Based on the different forms of the first message mentioned above, in step 1 above, when the device receives the first message sent by the reader, it can include the following two cases:

[0207] When the structure of the first message is as described in Form 1 above, after receiving the first message sent by the reader, the device can forward the target layer container contained in the first message to the target layer of the device. The target layer then performs integrity verification and / or security verification on the target layer container and parses the target layer container.

[0208] When the structure of the first message is of form 2, after the device receives the first message sent by the reader, the A-IoT AS layer forwards the first security type indication, the first integrity protection parameter and the first key parameter to the target layer, and the target layer performs integrity verification and / or security verification on the target layer container and parses the target layer container.

[0209] Example 4

[0210] In Example 4, assuming the first indication information includes a message type, the paging method may include:

[0211] Step 1: The device receives the first message sent by the reader. The first message contains first indication information, which includes a message identifier and random access parameters.

[0212] For example, the message identifier can be a numerical value, such as 6, which can be set according to actual needs. For example, in this embodiment of the disclosure, the message identifier is an information element of the A-IoT AS layer.

[0213] Step 2: The device performs a first response judgment. If it determines that a response is needed, it can perform random access based on the random access parameters in the first message and send a first response message to the reader.

[0214] The first response message includes the aforementioned message identifier.

[0215] Example 5

[0216] In Example 5, assuming the first indication information contains a message type, the paging method may include:

[0217] Step 1: The device receives the first message sent by the reader. The first message contains first indication information, which includes the message type.

[0218] For example, in this embodiment of the disclosure, the message type can indicate whether the first message type is an inventory service or a command service. Specifically, it can be implemented using a single bit; for example, 0 represents an inventory service and 1 represents a command service; or, 1 represents an inventory service and no occurrence represents a command service; or, 1 bit represents an inventory service and 1 bit represents a command service. This message type is an information element of the A-IoT AS layer.

[0219] Step 2: The device performs a first response check. If it determines that a response is needed, it sends a first response message to the reader.

[0220] For example, in this embodiment of the disclosure, if the message type indicates that the first message type is an inventory service, the first response message sent by the device to the reader may further include the device identifier fed back by the device; if the message type indicates that the first message type is a command service, the first response message sent by the device to the reader may further include a response to the command, specifically:

[0221] If the command is a read command, the response to the command is the information related to the command stored by the device. The device sends the information related to the command to the core network in the target layer container of the first response message.

[0222] If the command is a write command, the response to the command is an ACK, indicating whether the write was successful. The device sends this information to the core network in the target layer container of the first response message.

[0223] It is understood that the embodiments disclosed herein are merely illustrative examples of the four embodiments described above, but do not imply that the embodiments disclosed herein are limited to these.

[0224] Figure 4 is a schematic flowchart of another paging method provided in an embodiment of this disclosure. This paging method can be applied to a reading device. For example, as shown in Figure 4, the paging method may include:

[0228] It is contained within the target layer container, and the indication information is a non-plaintext information element;
