The second device can be a device accessing the network, which can be a terminal device in general, and specifically an environmental Internet of Things terminal device. An example of the communication system is shown in FIG. 1A, which includes a base station 11 and a terminal 12.

[0067] In the embodiments provided in the present application, the base station can be any kind of device with wireless transceiving function, including but not limited to: an evolved Node B (eNB or e-NodeB) in long term evolution (LTE), a base station (gNodeB or gNB) or a transmission receiving point (TRP) in new radio (NR), a base station in subsequent evolution of 3GPP, an access node in a Wi-Fi system, a wireless relay node, a wireless backhaul node, etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The base station can include one or more co-sited or non-co-sited transmission points (TRPs).

The terminal device can also be a fixed terminal device or a mobile terminal device.

[0069] In a communication system, an Ambient Internet of Things (AIoT) terminal device refers to an intelligent device that connects environment-related devices in the physical world to the Internet through embedded systems, sensors, communication technologies, and other means, and realizes the collection, transmission, processing and analysis of environment data, as well as the interaction and collaborative work with other devices or systems. Because the Ambient Internet of Things terminal device has the advantages of self-power supply and low power consumption, low cost and easy deployment, and wide applicability, the Ambient Internet of Things terminal device has been widely used in daily production and life.

[0070] Paging message is a mechanism used to find or notify a specific terminal device in a communication network. When the network has incoming calls, short messages or other data to be delivered to a terminal device in idle mode, the network device will send a paging message in a broadcast manner to wake up the terminal device and make it switch from idle mode to active mode to receive data. If the terminal device identifies its own identification information in the paging message, it will send a response message to the network device, indicating that it is ready to receive communication. For example, after receiving the paging message of the network device, the terminal device triggers a 2-step or 3-step random access process or triggers a non-contention-based random access process, i.e. the paging message is actually used to trigger the sending of inventory or commands. Once the terminal device responds, the network device stops the paging process and establishes the necessary signaling connection to deliver data.

[0071] In the use process of the environmental Internet of Things terminal device, it is usually necessary to involve paging the environmental Internet of Things terminal device. Specifically, as shown in FIG. 1B, the base station can directly page the environmental Internet of Things terminal device; as shown in FIG. 1C, the base station can also page the environmental Internet of Things terminal device through an intermediate node, where the intermediate node can be a mobile terminal device.

[0072] However, the information required for paging the environmental Internet of Things terminal device currently does not have a unified format standard, i.e. it is not clear whether the format of the information is designed based on a medium access control layer protocol data unit or a medium access control layer control element, which can easily cause the environmental Internet of Things terminal device to be unable to accurately parse the information required for paging.

[0073] In order to make the technical solutions of the present application more clear and easy to understand, the communication method of the embodiments of the present application will be introduced below in conjunction with the drawings. The communication method of the embodiments of the present application is applicable to the data transmission process in a wireless communication scenario. In the embodiments of the present application, data transmission between a terminal device and a network device is taken as an example, for example, data transmission between a single terminal device and a network device. The data transmission between the terminal device and the network device described above is only a feasible example, and the embodiments of the present application can be applied to data transmission between a terminal device and a terminal device, or data transmission between a network device and a network device, or data transmission between two network elements in a wireless communication network.

[0074] Please refer to FIG. 2, which shows an interaction flow between a network device and a terminal device provided by the embodiments of the present application. The embodiments of the present application provide a communication method, which mainly includes the following steps:

[0075] 201. The network device sends first information to the terminal device.

[0076] The first information includes control information and data information, wherein the control information is used to indicate reading of the data information, and the first information includes device identification information.

[0077] In the embodiment, the terminal device can receive the first information sent by the network device. The terminal device can be an environmental IoT terminal device, and the network device can be a base station or a mobile terminal device acting as an intermediate node, which can be represented by reader. It can be understood that the network device can send the first information to the terminal device, so that the terminal device can determine how to parse the data information in the first information through the control information included in the first information after receiving the first information from the network device, thereby enabling the terminal device to accurately parse the information required during paging. The device identification information can be information related to the device identification, and can include device identification control information and device identification data information.

[0078] 202. The terminal device receives the first information from the network device.

[0079] The first information includes control information and data information, wherein the control information is used to indicate reading of the data information, and the first information includes device identification information.

[0080] In the embodiment, the terminal device can receive the first information sent by the network device. Specifically, as shown in FIG. 3, the first information can be composed of control information and data information, wherein the control information is used to indicate how the terminal device specifically reads the data information, that is, the control information is used to indicate the way of reading the data information, so that the terminal device can determine how to parse the data information in the first information through the control information included in the first information, thereby enabling the terminal device to accurately parse the information required during paging. Specifically, the terminal device can receive the first information from the network device based on the paging message, and can also receive the first information based on the random access confirmation message and the physical random access channel, such as message 2 or message 4, and can also receive the first information based on the physical layer channel from the network device to the terminal device, such as R2D message of PRDCH (Physical reader to device channel).

[0081] In a possible implementation of the embodiment of the present application, the control information includes at least one of device identification control information and resource control information, the device identification control information is used to indicate device identification data information in the data information, and the resource control information is used to read resource data information in the data information. In the embodiment of the present application, as shown in FIG. 4, the control information can be composed of two kinds of information, i.e., device identification control information and resource control information, and the data information can include device identification data information and resource data information. The device identification control information is information related to device identification in the control information, and specifically can include at least one of a device identifier length indication field, a device identifier number indication field, a paging type indication field, a device identifier indication field, a data packet indication field, a data packet size indication field, a data packet device identifier indication field, and a network device identifier indication field. The device identification data information can be information related to device identification in the data information, and specifically can include at least one of a device identifier, a device group identifier, a first protocol layer data packet, a network device identifier, and a flow identifier. The resource control information can be information related to resources in the control information, and specifically can include at least one of a resource indication field, a random access type indication field, and a paging cause indication field. The resource data information can be information related to resources in the data information, and can include at least one of preconfigured resource information, frequency domain resource information, and time domain resource information.

[0082] The device identifier is an identifier of a device that needs to accept paging, that is, a terminal device corresponding to the device identifier needs to send a response message to the network device after receiving the first information. Specifically, the device identifier can be a random number ID determined by the device, or an identifier of the device itself, for example, an electronic product code (EPC), or an access layer system identifier (AS ID) between the network device and the terminal device, or an identifier between the core network and the device.

[0083] In a possible implementation of the embodiment of the present application, the device identification control information includes at least one of a device identifier length indication field, a device identifier number indication field, a paging type indication field, a device identifier indication field, and a network device identifier indication field.

[0084] In the embodiments of the present application, as shown in FIG. 5, the device identifier length field can be used to indicate the length of the device identifier in the device identification resource information, and can be specifically represented by "device ID length", and can indicate the length of one device identifier or the total length of all device identifiers included in the device identification data information. When the device identifier length indication field is included in the device identification control information and the device identification data information carries the device identifier, the terminal device can determine the length of the device identifier carried in the device identification data information through the device identifier length indication field, so as to accurately parse each device identifier from the device identification data information. It should be noted that if the terminal device knows that the length of the device identifier in the device identification data information is a fixed length, the terminal device can not determine the length of the device identifier through the device identifier length indication field in the device identification control information.

[0085] In addition, when the device identifier length field indicates the total length of all device identifiers included in the device identification data information, and the length of the device identifier of each device is fixed, the terminal device can determine the number of device identifiers in the device identification data information. For example, when the device identifier length field indicates that the total length of all device identifiers included in the device identification data information is 40 bits, and the length of the device identifier of each device is fixed as 5 bits, the terminal device can determine that the number of device identifiers in the device identification data information is 8.

[0086] In the embodiments of the present application, the device identifier number indication field can be used to indicate the number of device identifiers in the device identification data information, and can be specifically represented by "device ID number". The terminal device can determine the number of device identifiers carried in the device identification data information through the device identifier number indication field, so as to accurately parse all device identifiers from the device identification data information. It can be understood that when the device identification data information in the first information does not include the first protocol layer data packet, the device identifier number indication field can be used to indicate the number of device identifiers in the device identification data information; when the device identification data information in the first information includes the first protocol layer data packet, the device identifier number can indicate the number of other device identifiers in the device identification data information except for the device identifier included in the first protocol layer data packet, or can indicate the number of device identifiers included in the first protocol layer data packet, or can indicate the number of all device identifiers in the device identification data information.

[0087] Specifically, when the device identifier quantity indication field indicates that the quantity of device identifiers is greater than 0, the terminal device can determine that the device identifier is included in the device identification data information, and the quantity of device identifiers carried in the device identification data information is equal to the quantity indicated by the device identifier quantity indication field. The terminal device only needs to read the device identifier corresponding to the quantity indicated by the device identifier quantity indication field from the device identification data information, and can read the information in the device identification data information except the device identifier. For example, if the device identifier quantity indication field indicates that the quantity of device identifiers is 2, the device identification data information carries two device identifiers, and the terminal device only needs to read the two device identifiers from the device identification data information to read other information.

[0088] When the device identifier quantity indication field indicates that the quantity of device identifiers is equal to 0, the terminal device can determine that the device identifier is not included in the device identification data information, and does not need to read and analyze the device identifier from the device identification data information. It should be noted that when the device identifier quantity indication field indicates that the quantity of device identifiers is equal to 0, the terminal device can determine that the paging type corresponding to the first information is full paging, that is, the terminal device receiving the first information needs to respond and send a response message to the network device.

[0089] When the device identification data information in the first information includes the first protocol layer data packet, and the terminal device can only read the device identifier from the first protocol layer data packet, and the device identifier quantity indication field indicates that the quantity of device identifiers included in the first protocol layer data packet is 0, the terminal device can determine that the paging type corresponding to the first information is full paging, that is, the terminal device receiving the first information needs to respond and send a response message to the network device. Specifically, the device identifier quantity is used to indicate the quantity of device identifiers in the device identification data information except the first protocol layer data packet.

[0090] In the embodiment of the application, the paging type indication field can be used to indicate that the paging type corresponding to the first information is single paging, multiple paging, group paging or full paging, which can be represented by “paging type”. The terminal device can determine the specific paging type corresponding to the first information according to the paging type indication field in the device identification control information, and further determine whether the device identifier or the device group identifier is carried in the device identification data information, and specifically whether the device identifier or the device group identifier is carried.

[0091] Specifically, if the paging type indication field is used to indicate that the paging type corresponding to the first information is single paging, the terminal device can determine that the device identification data information carries one device identifier, i.e., the terminal device can parse one device identifier from the device identification data information. If the paging type indication field is used to indicate that the paging type corresponding to the first information is multiple paging, the terminal device can determine that the device identification data information carries multiple device identifiers, i.e., the terminal device can parse multiple device identifiers from the device identification data information. If the paging type indication field is used to indicate that the paging type corresponding to the first information is group paging, the terminal device can determine that the device identification data information carries a device group identifier, where the device group identifier can be represented as "device group ID", i.e., the terminal device can parse the device group identifier from the device identification data information. If the paging type indication field is used to indicate that the paging type corresponding to the first information is all paging, the terminal device can determine that the device identification data information does not carry a device identifier or a device group identifier. The device group identifier is an identifier of a group to which a device that needs to accept paging belongs, i.e., all terminal devices in the group corresponding to the device group identifier need to send a response message to the network device after receiving the first information.

[0092] In addition, if the device identification control information does not include the paging type indication field, and the device identification data information includes a device group identifier or a device identifier, the format of the device group identifier is different from the format of the device identifier. It can be understood that if the paging type indication field is not included in the device identification control information, the paging type corresponding to the first information can be single paging, multiple paging, or group paging. When the paging type corresponding to the first information is single paging or multiple paging, the device identification data information carries a device identifier; when the paging type corresponding to the first information is group paging, the device identifier included in the data information can be specifically a device group identifier, and the format of the device identifier and the format of the device group identifier can be different, so that the terminal device can determine the paging type corresponding to the first information by identifying the format of the device identifier or the device group identifier.

[0093] It should be noted that group paging is a one-to-many or many-to-many communication mode, which means that the network device needs to find a group of terminal devices, and is mainly used for sending the same message to multiple individuals in the same group, and each group of devices has a group identifier. Global paging can be referred to as global inventory, which means that the network device needs to send a downlink command to all terminal devices, corresponding to local paging. Local paging is paging of terminal devices in a specific location area, that is, when the network device knows the current location area of the terminal device, it only sends a paging message in the location area. However, if the network device does not know the exact location of the terminal device, or the terminal device has moved to another location area, the network device needs to perform global paging, that is, send a paging message in a larger range to try to find and contact the terminal device.

[0094] The device identifier indication field can be used to indicate whether the device identifier or the device group identifier exists in the device identification data information, and can specifically be represented by "E1". The terminal device can determine whether the device identifier or the device group identifier is carried in the device identification data information according to the device identifier indication field in the device identification control information.

[0095] Specifically, if the device identifier indication field indicates that the device identifier or the device group identifier exists in the device identification data information, the device identification data information carries the device identifier or the device group identifier, that is, the terminal device can parse the device identifier or the device group identifier from the device identification data information. If the device identifier indication field indicates that the device identifier or the device group identifier does not exist in the device identification data information, the device identification data information does not carry the device identifier or the device group identifier, that is, the terminal device does not need to parse the device identifier or the device group identifier from the device identification data information; when the device identification data information includes a first protocol layer data packet, the device identifier indication field can indicate that the device identification data information does not include the device identifier; or the device identifier indication field can indicate that the device identification data information does not include the device identifier except for the part of the first protocol layer.

[0096] In the embodiment of the application, the network device identifier indication field can be used to indicate whether the network device identifier exists in the device identification data information, and can specifically be represented by "R2", that is, the terminal device can determine whether the network device identifier exists in the device identification data information according to the network device identifier in the device identification information. The network device identifier is the identification information of the network device sending the first information, and can specifically be represented by "reader ID".

[0097] In a possible implementation of the embodiment of the present application, the device identifier control information can further include a device identifier type indication field, which is used to indicate the specific type of the device identifier or to indicate whether there is a specific type of device identifier. If there is a specific type of device identifier, the specific type of device identifier is used; if there is no specific type of device identifier, a random number ID is used. In the embodiment of the present application, the type of the device identifier can include at least one of a device-determined random number ID, an identifier of the device itself, for example, an Electronic Product Code (EPC), or an Access Layer System Identifier (AS ID) between the network device and the terminal device, or an identifier between the core network and the device. The terminal device can determine, according to the device identifier type indication field, which type of device identifier is used for data transmission, for example, if the device identifier type indication field indicates that the specific type of the device identifier is the AS ID, the terminal device can use the AS ID for data transmission; if the device identifier type indication field indicates that the specific type of the device identifier is the random number ID, the terminal device can use the random number ID for data transmission.

[0098] In a possible implementation of the embodiment of the present application, the device identifier control information includes at least one of a data packet indication field, a data packet size indication field, and a data packet device identifier indication field.

[0099] In the embodiment of the present application, as shown in FIG. 6, the data packet indication field can be used to indicate whether the device identifier data information includes a first protocol layer data packet, and can be represented by "N1". When the data packet indication field in the device identifier control information indicates that the device identifier data information includes the first protocol layer data packet, the device identifier data information carries the first protocol layer data packet, and the terminal device can parse the first protocol layer data packet from the device identifier data information.

[0100] The first protocol layer data packet can be a data packet configured by the first protocol layer of the network device, can be represented by "NAS PDU", or can be a data packet used to indicate the core network, or a data packet of the first protocol layer higher than the current protocol layer, and the first protocol layer data packet can encapsulate at least one of a device identifier, a device group identifier, and downlink command information.

[0101] Further, the first protocol layer data packet can also include a device identifier quantity field, which is used to indicate the quantity of device identifiers carried in the first protocol layer data packet, and can be represented by a field Q in a conversion relationship with the quantity of device identifiers, so that the terminal device can determine how many device identifiers are carried in the first protocol layer data packet, thereby enabling the terminal device to accurately parse the information required during paging. The first protocol layer data packet can also carry a device identifier length indication field, a device identifier quantity indication field, and a device identifier indication field, etc.

[0102] It should be noted that if the data packet indication field indicates that the first protocol layer data packet is not carried in the device identifier data information, the terminal device can determine that the paging type corresponding to the first information is full paging.

[0103] In the embodiments of the present application, the data packet size indication field is used to indicate the number of bytes or bits occupied by the first protocol layer data packet, which can be specifically represented by "N2". The terminal device can determine the number of bytes or bits occupied by the first protocol layer data packet according to the data packet size indication field in the device identifier control information, so as to be able to parse and read out the complete first protocol layer data packet from the device identifier data information.

[0104] In the embodiments of the present application, the data packet device identifier indication field can be used to indicate whether to read the device identifier or device group identifier from the first protocol layer data packet, which can be specifically represented by "N3". The terminal device can determine whether it needs to read the device identifier or device group identifier from the first protocol layer data packet according to the data packet device identifier indication field in the device identifier control information. It can be understood that if the data packet device identifier indication field indicates that the terminal device reads the device identifier or device group identifier from the first protocol layer data packet, the first protocol layer data packet in the device identifier data information carries the device identifier or device group identifier.

[0105] Specifically, if the data packet device identifier indication field indicates that the device identifier or device group identifier is read from the first protocol layer data packet, the first protocol layer data packet carries the device identifier or device group identifier, i.e., the terminal device can parse the device identifier or device group identifier from the first protocol layer data packet. If the device identifier indication field indicates that the device identifier or device group identifier is not read from the first protocol layer data packet, the first protocol layer data packet carries downlink command information, i.e., the terminal device can only parse the downlink command information from the first protocol layer data packet of the device identifier data information, and cannot parse the device identifier or device group identifier from the first protocol layer data packet of the device identifier data information, but should parse the device identifier or device group identifier from other information of the device identifier data information.

[0106] In a possible implementation of the embodiment of the present application, the device identifier control information further includes first indication information, and the first indication information is used to indicate whether the device identifier exists. In the embodiment of the present application, since the device identifier carried in the device identifier data information can be the identifier of the device that needs to accept the current paging or the identifier of the device that needs to ignore the current paging, the device identifier control information can further carry the first indication information corresponding to each device identifier, that is, each device identifier has a corresponding first indication information, so that the terminal device can determine which device identifier needs to be identified and judged and which device identifier can be ignored.

[0107] In a possible implementation of the embodiment of the present application, if the first indication information indicates that the device identifier corresponding to the first indication information does not exist, the first indication information is further used to indicate the field information after the device identifier corresponding to the first indication information. In the embodiment of the present application, if the first indication information indicates that the device identifier does not exist, the terminal device can skip the device identifier and directly read the field information after the device identifier, so that the terminal device can accurately parse the information required at the time of paging. For example, the field information after the device identifier in the data information is resource information, and the first indication information of the device identifier indicates that the device identifier does not exist, so the terminal device can skip the device identifier and directly read the resource information after the device identifier.

[0108] It should be noted that, as shown in FIG. 7, the device identifier length indication field, the device identifier number indication field, the paging type indication field, the device identifier indication field, the data packet indication field, the data packet size indication field, the network device identifier indication field, the data packet device identifier indication field, the device identifier, the device group identifier, the first protocol layer data packet, the network device identifier and the like can exist in the first information at the same time.

[0109] In a possible implementation of the embodiment of the present application, as shown in FIG. 8, the resource control information can include a resource indication field.

[0110] In the embodiment of the present application, the resource indication field is used to indicate whether the resource data information exists in the data information, and can be specifically represented by “R1”. The terminal device can determine whether the resource data information can be parsed from the data information according to the resource control information, that is, whether the network device is allocated with the resource data information used for data transmission can be determined.

[0111] Specifically, if the resource indication field is used to indicate that there is no resource data information in the data information, the resource indication field can also be used to indicate that the response message is sent using a predefined resource. It can be understood that the predefined resource can include at least one of a default frequency domain resource and a default time limit, wherein the default frequency domain resource is a frequency domain resource information set when the device is manufactured or a predefined frequency domain resource information, and the default time limit can be a time limit set in advance according to actual conditions. The terminal device can send a response message to the network device immediately after receiving the first message.

[0112] In a possible implementation manner of the embodiment of the present application, the resource indication field can be used to indicate that the response message is sent using a preconfigured resource. In the embodiment of the present application, the terminal device can determine whether the network device indicates that the response message is sent through the preconfigured resource according to the resource control information, that is, the terminal device can determine whether the response message needs to be sent through the preconfigured resource, so that the terminal device can accurately parse the information required at the time of paging. The preconfigured resource is a previously configured transmission resource received by the terminal device.

[0113] Specifically, the preconfigured resource information can be included in the resource data information. The preconfigured resource information can be used to determine the preconfigured resource, and specifically can be index information of the preconfigured resource. When multiple preconfigured resources are included in the data information, the resource information in the data information can also include the index of the preconfigured resource, which is used to indicate which preconfigured resource is used by the terminal device for data transmission, that is, the terminal device can determine how to specifically parse the data information in the first information through the control information included in the first information, so that the terminal device can accurately parse the information required at the time of paging.

[0114] In a possible implementation of the embodiment of the present application, the resource indication field includes at least one of a frequency domain resource indication field and a time domain resource indication field, the frequency domain resource indication field is used to indicate whether there is frequency domain resource information in the resource data information, and the time domain resource indication field is used to indicate whether there is time domain resource information in the resource data information. In the embodiment of the present application, the terminal device can determine whether the network device is allocated with frequency domain resources and whether the network device is allocated with time domain resources according to the frequency domain resource indication field and the time domain resource indication field in the resource indication field respectively, wherein the frequency domain resource indication field can be represented by "RF", and the time domain resource indication field can be represented by "RT". When the frequency domain resource indication field in the resource control information indicates that there is frequency domain resource information, the frequency domain resource information can be carried in the resource data information; when the resource indication field in the resource control information indicates that there is time domain resource information, the time domain resource information can be carried in the resource data information, so that the terminal device can parse the frequency domain resource information or the time domain resource information in the data information based on the control information, thereby enabling the terminal device to accurately parse the information required in paging.

[0115] Specifically, the frequency domain resource information carried by the resource data information can include at least one of frequency division multiplexing value, frequency domain width and frequency point information. Wherein the frequency division multiplexing value can be indexed by a table, for example, the frequency division multiplexing value is 1, 2, 4 or 8, then 2 bits can be used for representation, 00 is 1, 01 is 2, 10 is 4, and 11 is 8. The time domain resource information carried by the resource data information can include at least one of time domain number and time slot length. Specifically, when the time slot number is 0, the time domain resource information indicates that the time when the terminal device receives the first information is the current time slot; when there is indication information indicating the current time slot or the start of the time slot, the time slot number is 0 to indicate that the first information indicates the start of the time slot; when the time slot number is 1, the indication information can indicate the start of the time slot, for example, based on the received first information, the indication information is received to determine the start of the time slot, and a response is performed. When the time slot information is not included in the data information, the first information indicates the current time slot or the start of the time slot, which means that there is only one time slot. There can also be a default mode, when the time slot number is 1, the first information indicates the current time slot or the start of the time slot, and no additional indication information is required to indicate the start of the time slot.

[0116] In a possible implementation of the first aspect of the present application, if the resource indication field indicates that only time domain resource information is included in the resource data information, the resource indication field is further used to indicate that the response message is sent using a default frequency domain resource; if the resource indication field indicates that only frequency domain resource information is included in the resource data information, the resource indication field is further used to indicate that the response message is sent within a default time limit. In the embodiment of the present application, when the terminal device determines that only time domain resources are allocated by the network device according to the resource indication field, the terminal device can send the response message using the default frequency domain resource; when the terminal device determines that only frequency domain resources are allocated by the network device according to the resource indication field, the terminal device can send the response message within the default time limit, so that the terminal device can accurately parse the information required for paging.

[0117] In a possible implementation of the first aspect of the present application, the resource control information can further include at least one of a random access type indication field and a paging cause indication field. In the embodiment of the present application, the random access type indication field is used to indicate the random access type of the terminal device, which can be specifically denoted as “RA type”. The terminal device can determine the random access type of the terminal device indicated in the data information according to the random access type indication field, and the random access type can specifically include contention free random access (CFRA), 2-step contention based random access (2-step CBRA) or 3-step contention based random access (3-step CBRA). The paging cause indication field can be used to indicate the paging reason corresponding to the first information, which can be specifically denoted as “D”. The terminal device can also determine the specific paging reason for sending the first information by the network device through the paging cause indication field in the control information, and the paging reason can include receiving a downlink command message, performing device inventory, or repeatedly paging a device that fails to accept the paging.

[0118] In a possible implementation of the first aspect of the present application, the first information can further include a tag identifier R and a flow identifier used to identify whether it is the same paging, which can be denoted as “flow ID”. The terminal device can determine whether the paging corresponding to the first information is a repeated paging through the flow identifier.

[0119] In a possible implementation of the first aspect of the present application, the first information is encapsulated in the first data packet and the second data packet, the first data packet is encapsulated based on a first protocol layer, and the second data packet is encapsulated based on a second protocol layer. In the embodiments of the present application, the first information can be composed of two different data packets respectively, and the two different data packets can be encapsulated by two different protocol layers respectively, that is, part of the information in the first information can be generated by the first protocol layer, and another part of the information in the first information can be generated by the second protocol layer, thereby improving the security of the information carried in the first information.

[0120] In a possible implementation of the first aspect of the present application, the first data packet includes device identification control information and device identification data information, and the second data packet includes resource control information and resource data information. In the embodiments of the present application, as shown in FIG. 9, the device identification control information and the device identification data information in the first information can be encapsulated in the first data packet, and the resource control information and the resource data information in the first information can be encapsulated in the second data packet, that is, the device identification control information and the device identification data information in the first information can be generated by the first protocol layer, and the resource control information and the resource data information in the first information can be generated by the second protocol layer, thereby improving the security of the information carried in the first information.

[0121] Specifically, the first data packet can include at least one of a device identifier length indication field, a device identifier number indication field, a paging type indication field, a device identifier indication field, a data packet indication field, a data packet size indication field, a data packet device identifier indication field, a network device identifier indication field, a device identifier, a device group identifier, a first protocol layer data packet, a network device identifier, a flow identifier, and downlink command information.

[0122] The second data packet can include at least one of a resource indication field, a random access type indication field, a paging cause indication field, preconfigured resource information, frequency domain resource information, and time domain resource information.

[0123] In addition, if the first protocol layer data packet only includes downlink command information, the second data packet can also encapsulate part of the device identifier control information and part of the device identifier data information. For example, the first data packet can include downlink command information, and the second data packet can include at least one of a device identifier length indication field, a device identifier number indication field, a paging type indication field, a device identifier indication field, a data packet indication field, a data packet size indication field, a network device identifier indication field, a data packet device identifier indication field, a device identifier, a device group identifier, a first protocol layer data packet, a network device identifier, a flow identifier, a resource indication field, a random access type indication field, a paging cause indication field, preconfigured resource information, frequency domain resource information, and time domain resource information.

[0124] In a possible implementation of the first aspect of the present application, the first data packet is transmitted based on a protocol data unit, and the second data packet is transmitted based on a medium access control layer control element. In the embodiments of the present application, after encapsulating the device identifier control information and the device identifier data information in the first information in the first data packet and encapsulating the resource control information and the resource data information in the first information in the second data packet, the first data packet can be transmitted based on a protocol data unit (PDU), and the second data packet can be transmitted based on a medium access control layer control element (MAC CE).

[0125] 203. The terminal device determines whether to send a response message to the network device according to the first information.

[0126] In the embodiments of the present application, after receiving the first information from the network device, the terminal device can determine how to parse the data information in the first information through the control information included in the first information, and can determine whether the terminal device needs to respond based on the first information and send a response message to the network device according to the parsed information.

[0127] In a possible implementation of the embodiments of the present application, the step 203 of determining whether to send a response message to the network device according to the first information includes:

[0128] A1. If the paging type indication field is used to indicate that the paging type corresponding to the first information is single paging or multiple paging, and the identifier of the terminal device matches the device identifier, the terminal device determines to send a response message to the network device.

[0129] A2. If the paging type indication field is used to indicate that the paging type corresponding to the first information is group paging, and the identifier of the terminal device matches the device group identifier, the terminal device determines to send a response message to the network device.

[0130] A3, if the paging type indication field is used to indicate that the paging type corresponding to the first information is a full paging, the terminal device determines to send a response message to the network device.

[0131] In the embodiments of the present application, after the terminal device parses the first information, if the paging type indication field is used to indicate that the paging type corresponding to the first information is a single paging or a multiple paging, the terminal device can parse the device identifier from the device identification data information. At this time, if the identifier of the terminal device matches the device identifier parsed from the device identification data information, the terminal device can determine that it needs to send a response message to the network device. If the paging type field in the control information is used to indicate that the paging type corresponding to the first information is a group paging, the terminal device can parse the device group identifier from the device identification data information. At this time, if the identifier of the terminal device matches the device group identifier parsed from the device identification data information, the terminal device can determine that it needs to send a response message to the network device. If the paging type field in the control information is used to indicate that the paging type corresponding to the first information is a full paging, the terminal device can determine that it needs to send a response message to the network device, so that the terminal device can accurately parse the information needed at the time of paging and determine whether it needs to send a response message to the network device.
