[0199] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0200] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0201] Optionally, in some embodiments of the present disclosure, the Internet of Things (IoT) has connected billions of devices to the internet, and cellular IoT technologies such as LTE-M and NB-IoT have made significant progress in enabling use cases across a wide range of vertical industries. However, many IoT devices rely on batteries. Recently, IoT technology has evolved to include ambient energy harvesting, a method for generating electricity from the environment without relying on batteries.

[0202] Optionally, in some embodiments of the present disclosure, leveraging the ubiquitous deployment and abundant system capacity of 5G systems, ambient power-enabled IoT technologies offer 5G MNOs a potential opportunity to expand their 3GPP IoT service portfolios, support new types of devices, and address use cases where battery replacement is considered inefficient and / or environmentally problematic. These use cases include personalized healthcare, smart transportation, industrial applications in hazardous locations, smart logistics, smart warehousing, smart homes, and smart cities. New battery-free devices with limited energy storage capabilities complement existing cellular IoT services and are characterized by low cost, high density, large deployment volumes, and ultra-low complexity, i.e., devices with limited functionality and limited capabilities that require only small and infrequent data transmissions.

[0203] Optionally, FIG2 is a schematic diagram illustrating an example of a network-triggered service request process provided by an embodiment of the present disclosure. As shown in FIG2 , the service request process includes:

[0204] Step 1: UPF receives downlink data;

[0205] Step 2a: Data notification: UPF sends a data notification message to SMF;

[0206] Step 2b: Data notification confirmation: SMF feeds back data notification confirmation to UPF;

[0207] Step 2c: UPF sends downlink data to SMF: If SMF instructs UPF to perform this step, UPF forwards the downlink data packet to SMF (i.e., SMF buffers the data packet);

[0208] Step 3a: Namf-Communication-N1N2 message transmission: SMF sends a Network Access and Mobility Management Function (Namf)_Communication_N1N2 message transmission request to AMF, which includes (SUPI, PDU session ID, N1 session management (SM) container (SM message), N2SM information (Quality of Service (QoS) flow identifier, QoS profile, CN N3 tunnel information, s-Network Slice Selection Assistance Information (NSSAI)); where CN N3 can be, for example, the N3 interface of the core network;

[0209] Step 3b: namf-communication-N1N2 message transmission response;

[0210] Step 4a: Reactivation: If the terminal is in the Connection Manager (CM)-CONNECTED state in the access associated with the PDU Session ID received from the SMF in step 3a, the terminal triggers steps 4 to 22 of the service request procedure (see clause 4.2.3.2) to be performed for this PDU Session (i.e., radio resources are established and, in case the user plane is to be activated, an N3 tunnel is established) without sending a paging message to the Radio Access Network (R)AN) node and the terminal;

[0211] Step 4b: Paging: When the terminal is in the CM_IDLE state, the AMF sends a CN paging message to the RAN. The RAN sends a paging message to the terminal;

[0212] Step 4c: NAS notification;

[0213] Step 5: Namf-Communication-N1N2 transmission failure notification: AMF sends Namf_Communication_N1N2 transmission failure notification to SMF;

[0214] Step 6: Service Request Procedure: If the terminal is in the CM-IDLE state in a 3rd Generation Partnership Project (3GPP) access, upon receiving a paging request for a Packet Data Unit (PDU) session associated with the 3GPP access, the terminal shall initiate a terminal-triggered service request procedure to enter the CM_CONNECTED state to activate / create a user plane connection for delivering downlink data.

[0215] Step 6a: Namf-Communication-N1N2 transmission failure notification: AMF sends Namf_Communication_N1N2 transmission failure notification to SMF;

[0216] Step 7: Terminal Configuration Update Procedure: If the AMF has paged the terminal to trigger the Service Request procedure, the AMF shall initiate the Terminal Configuration Update procedure defined in clause 4.2.4.2 to allocate a new 5th Generation Mobile Communication Technology (5G) Globally Unique Temporary Identifier (GUTI);

[0217] Step 8: The UPF sends the buffered downlink data to the terminal through the (R)AN node that performs the service request procedure.

[0218] In one embodiment of the present disclosure, when there is downlink data from the network to the terminal, the network triggers paging the terminal, and a connection must be created between the terminal and the RAN, for example, by triggering a service request procedure to enter a connected state, and / or activating / creating a user plane connection to download downlink data from the network. The terminal can, for example, receive a paging message sent by an access network device, but needs to trigger an NSA signal to establish a connection to receive downlink data. However, for ambient IoT devices, the downlink data may be very small, for example, a few bits dedicated to instructions, and ambient IoT devices are defined as passive devices or devices with very limited power, so the above process is not necessary and effective. Among them, a passive device can, for example, be a device without a power supply.

[0219] Optionally, in one embodiment of the present disclosure, the paging message can be extended to include additional information without establishing a connection between the terminal and the access network device. This can save message transmission resources and improve message transmission efficiency. However, directly transmitting the message as a single paging message results in poor security.

[0220] The following describes in detail a message receiving method, apparatus, device, and storage medium provided by embodiments of the present disclosure with reference to the accompanying drawings.

[0221] FIG3A is an interactive diagram of a message receiving method provided by an embodiment of the present disclosure. As shown in FIG3A , the method may include the following steps:

[0222] Step S3101: The SMF sends a downlink data notification to the access and mobility management function (AMF), where the downlink data notification instructs the AMF to send at least one paging message to the access network device, where the at least one paging message includes information for instructing the terminal to perform an operation.

[0223] Optionally, in one embodiment of the present disclosure, the downlink data notification may include, for example, an environmental Internet of Things (IoT) instruction.

[0224] Optionally, in one embodiment of the present disclosure, the terminal may be, for example, an ambient IoT device. Different paging messages may include different information. This information may be, for example, a multi-bit instruction. This multi-bit instruction may be, for example, an instruction for the ambient IoT device. For example, when the number of bits corresponding to the instruction changes, the information may also change accordingly.

[0225] Optionally, any paging message of the at least one paging message includes at least one of the following information:

[0226] Instruction information;

[0227] Verify information.

[0228] Optionally, in one embodiment of the present disclosure, any paging message includes instruction information.

[0229] Optionally, in one embodiment of the present disclosure, any paging message includes verification information.

[0230] In conjunction with some embodiments of the first aspect, in some embodiments, the instruction information includes at least one of the following:

[0231] Encrypted instruction information;

[0232] Unencrypted command information.

[0233] Optionally, in one embodiment of the present disclosure, the access network device may be, for example, a RAN.

[0234] Step S3102: The AMF receives the downlink data notification sent by the session management function SMF and sends at least one paging message to the access network device, where the at least one paging message includes information for instructing the terminal to perform an operation;

[0235] Optionally, in one embodiment of the present disclosure, different paging messages may include different information. For example, an operation instruction may be included in different paging messages. For example, an operation instruction may be included in one paging message, and verification information corresponding to the operation instruction may be included in at least one other paging message.

[0236] Optionally, in one embodiment of the present disclosure, the at least one paging message received by the terminal may be, for example, three paging messages. The three paging messages may be, for example:

[0237] Paging message 1 ("Command")

[0238] Paging message 2 ("Verification code 1")

[0239] Paging message 3 ("Verification Code 2").

[0240] In one embodiment of the present disclosure, paging message 1, paging message 2, and paging message 3 correspond to the same operation instruction.

[0241] In one embodiment of the present disclosure, for example, whether paging message 1, paging message 2, and paging message 3 correspond to the same operation instruction can be determined based on paging message indication information in the paging configuration parameters. The paging message indication information can be pre-configured or determined by the core network device based on the terminal's registration request.

[0242] The paging message indication information in the paging configuration parameters may be used to indicate which paging messages correspond to the same operation instruction, for example. The paging message indication information may be a parameter in at least one paging message.

[0243] Optionally, in one embodiment of the present disclosure, whether at least one paging message corresponds to the same operation instruction can be determined, for example, based on the bit value of a certain fixed bit position in the at least one paging message. For example, if the bit value of a certain fixed bit position in the at least one paging message is the same, it can be determined that the at least one paging message corresponds to the same operation instruction.

[0244] Optionally, in an embodiment of the present disclosure, for example, if the third bit value in paging message 1, paging message 2 and paging message 3 is the same, it can be determined that paging message 1, paging message 2 and paging message 3 correspond to the same operation instruction.

[0245] Optionally, in one embodiment of the present disclosure, the at least one paging message received by the terminal may be, for example, three paging messages. The three paging messages may be, for example:

[0246] Paging message 1 ("parameter 1")

[0247] Paging message 2 ("parameter 2")

[0248] Paging message 3 ("parameter 3").

[0249] In one embodiment of the present disclosure, the parameters in paging message 1, paging message 2, and paging message 3 together constitute the same operation instruction. For example, parameter 1, parameter 2, and parameter 3 together constitute the same operation instruction.

[0250] Step S3103: The access network device receives at least one paging message sent by the access and mobility management function (AMF), where the at least one paging message includes information for instructing the terminal to perform an operation.

[0251] Step S3104: The access network device sends at least one paging message to the terminal;

[0252] Optionally, in an embodiment of the present disclosure, for example, the access network device may determine a paging resource corresponding to at least one paging message, and use the paging resource to send the at least one paging message to the terminal.

[0253] Optionally, in one embodiment of the present disclosure, the paging resource may be, for example, a resource used to physically carry a paging message. Different paging messages may correspond to different paging resources. For example, the paging resource may be an air interface wireless resource, such as a frequency domain resource or a time domain resource.

[0254] Optionally, in one embodiment of the present disclosure, the paging resource includes at least one of the following:

[0255] At least one paging occasion (PO);

[0256] At least one paging frequency information.

[0257] Optionally, in one embodiment of the present disclosure, paging resources may include, for example, paging period A, paging period B, and paging period C. At least one paging message may include, for example, paging message 1, paging message 2, and paging message 3. For example, paging message 1 may be sent in paging period A, paging message 2 may be sent in paging period B, and paging message 3 may be sent in paging period C. The sending of paging message 1 in paging period A may, for example, be a paging period A-carrying instruction.

[0258] Optionally, in one embodiment of the present disclosure, different paging messages may include different information, and different paging messages may correspond to the same operation instruction. For example, paging message 1 may include instruction information, paging message 2 may include verification information 1, and paging message 3 may include verification information 2.

[0259] In one embodiment of the present disclosure, the terminal may determine whether paging message 1, paging message 2, and paging message 3 correspond to the same operation instruction, for example, based on paging message indication information in the paging configuration parameters. The paging message indication information may be pre-configured in the terminal or may be a parameter determined by a core network device based on a registration request from the terminal.

[0260] Step S3105: The terminal receives at least one paging message sent by the access network device;

[0261] Optionally, in an embodiment of the present disclosure, the terminal receives at least one paging message sent by the access network device, for example according to pre-configured paging configuration parameters, to determine that the at least one received paging message corresponds to the same operation instruction.

[0262] Optionally, in one embodiment of the present disclosure, the terminal may receive at least one paging message sent by the access network device, for example, based on the received paging configuration parameters sent by the access network device, to determine that the at least one received paging message corresponds to the same operation instruction. The paging message indication information in the paging configuration parameters may, for example, be used to indicate which paging messages correspond to the same operation instruction. The paging message indication information may, for example, be a parameter in the at least one paging message.

[0263] Optionally, in one embodiment of the present disclosure, whether at least one paging message corresponds to the same operation instruction can be determined, for example, based on the bit value of a certain fixed bit position in the at least one paging message. For example, if the bit value of a certain fixed bit position in the at least one paging message is the same, it can be determined that the at least one paging message corresponds to the same operation instruction.

[0264] Step S3106: The terminal obtains an operation instruction in at least one paging message;

[0265] Optionally, in one embodiment of the present disclosure, the terminal may derive an operation instruction based on information included in all paging messages in the at least one paging message. The operation instruction may be, for example, an instruction derived from the at least one paging message after the terminal verifies the at least one paging message. For example, at least one paging message may correspond to one operation instruction.

[0266] Optionally, in one embodiment of the present disclosure, the at least one paging message received by the terminal may be, for example, three paging messages. The three paging messages may be, for example:

[0267] Paging message 1 ("Command")

[0268] Paging message 2 ("Verification code 1")

[0269] Paging message 3 ("Verification Code 2").

[0270] When the verification code 1 in the paging message 2 and the verification code 2 in the paging message 3 are verified successfully, the instruction in the paging message 1 can be obtained. The instruction can be, for example, an operation instruction obtained by the terminal, wherein the instruction can be, for example, an open instruction.

[0271] Optionally, in an embodiment of the present disclosure, when the terminal receives at least one paging message, if any one of the at least one paging message includes verification information, the verification information may be verified.

[0272] Optionally, in one embodiment of the present disclosure, the verification information may be, for example, a verification code. The terminal may, for example, verify the verification code in at least one paging message. The verification of the verification code may, for example, verify whether the verification code is consistent with the expected verification code. The expected verification code may, for example, be pre-configured in the terminal. For example, when verification code 1 is the same as verification code 1 configured in the terminal, and verification code 2 is the same as verification code 2 configured in the terminal, an operation instruction in at least one paging message may be obtained. When verification code 1 is different from verification code 1 configured in the terminal, or verification code 2 is different from verification code 2 configured in the terminal, the terminal may discard the at least one paging message. When verification code 1 is different from verification code 1 configured in the terminal, and verification code 2 is different from verification code 2 configured in the terminal, the terminal may discard the at least one paging message.

[0273] Optionally, in one embodiment of the present disclosure, the at least one paging message received by the terminal may be, for example, three paging messages. The three paging messages may be, for example:

[0274] Paging message 1 ("parameter 1")

[0275] Paging message 2 ("parameter 2")

[0276] Paging message 3 ("parameter 3").

[0277] When the terminal receives all three paging messages, it can obtain parameter 1, parameter 2, and parameter 3. The terminal combines the three parameters to obtain the combined parameters and obtain the operation instructions corresponding to the combined parameters.

[0278] In one embodiment of the present disclosure, upon receiving at least one paging message, the terminal may determine whether the at least one paging message corresponds to the same operation instruction based on, for example, paging message indication information in a paging configuration parameter. The paging message indication information may, for example, be a parameter in the at least one paging message that indicates which paging messages correspond to the same operation instruction.

[0279] Optionally, in one embodiment of the present disclosure, paging configuration parameters may include, for example, paging extension information supported by a terminal, a time domain for monitoring at least one paging message, specific additional information included in any paging message, and paging message indication information. The paging message indication information may, for example, indicate multiple paging messages corresponding to a single operation instruction. The paging extension information may, for example, indicate specific additional information included in paging messages supported by the terminal.

[0280] Optionally, in one embodiment of the present disclosure, whether at least one paging message corresponds to the same operation instruction can be determined, for example, based on the bit value of a fixed bit position in at least one paging message. For example, if the bit value of the third bit in paging message 1, paging message 2, and paging message 3 is the same, it can be determined that paging message 1, paging message 2, and paging message 3 correspond to the same operation instruction.

[0281] Optionally, in an embodiment of the present disclosure, the paging message indication information may be directly configured in the terminal, or may be sent to the terminal by a core network device.

[0282] Step S3107: The terminal executes an operation corresponding to the operation instruction in the at least one paging message.

[0283] Optionally, in one embodiment of the present disclosure, the terminal may store an instruction table, for example. The instruction table may include instructions and operations corresponding to the instructions. When the terminal obtains an operation instruction corresponding to at least one paging message, the terminal may perform a corresponding action according to the instruction table and the operation instruction.

[0284] Optionally, in one embodiment of the present disclosure, when the terminal device receives at least one paging message, it can obtain the information included in all paging messages in the at least one paging message, and perform corresponding operations according to the operation instructions corresponding to the information included in all the paging messages.

[0285] In the above embodiment, since different paging messages may include different information, and these different multiple information together constitute an operation instruction, the situation where the security of paging message transmission is poor when the paging message is transmitted in the form of a paging message can be reduced, the probability of the paging message being successfully attacked and cracked during transmission can be reduced, and the security of message transmission can be improved.

[0286] The communication method according to the embodiment of the present disclosure may include at least one of steps S3101 to S3107. For example, step S3101 may be implemented as an independent embodiment, step S3107 may be implemented as an independent embodiment, and steps S3105 to S3107 may be implemented as independent embodiments, but are not limited thereto.

[0287] In some embodiments, steps S3108 and 3101 may be executed in an interchanged order or simultaneously.

[0288] In some embodiments, steps S3108 to S3121 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0289] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 3A .

[0290] In the above embodiment, a paging message transmission mechanism can be provided, and different paging messages can include different information, thereby reducing the situation where the security of paging message transmission is poor when the paging message is transmitted in the form of a paging message, reducing the probability of successful attack and cracking during instruction transmission, and improving the security of message transmission.

[0291] FIG3B is an interactive schematic diagram of a message receiving method provided by an embodiment of the present disclosure, wherein the message receiving method shown in FIG3B may be a further operation process of the message receiving method shown in FIG3A. FIG3B may, for example, be a solution with more operation steps added to the message receiving method shown in FIG3A, or a more specific description of a step in FIG3A. For example, steps S3108 to S3118 are added to the technical solution of FIG3B. For example, step S3119 in FIG3B may be a specific operation process of step S3105 in FIG3A.

[0292] As shown in FIG3B , the method may include the following steps:

[0293] Step S3108: The terminal sends a registration request to the access network device, where the registration request includes indication information for instructing the AMF extended paging message;

[0294] Optionally, in one embodiment of the present disclosure, the indication information may include, for example, information for instructing the AMF to extend the paging message, and may also include information indicating whether the terminal supports paging message extension. Extending the paging message may, for example, include adding non-paging information to the paging message.

[0295] Step S3109: The access network device receives the registration request sent by the terminal, where the registration request includes indication information for indicating an AMF extended paging message;

[0296] Step S3110: The access network device sends a registration request to the access and mobility function AMF.

[0297] Step S3111: The AMF receives a registration request sent by the access network device, where the registration request includes indication information for instructing the AMF to extend the paging message.

[0298] Step S3112: The AMF determines whether to accept the registration request based on at least one of local policy and network capabilities.

[0299] Optionally, in one embodiment of the present disclosure, the local policy may be, for example, a policy included in the AMF.

[0300] Step S3113: The AMF determines that the registration request is accepted and sends a registration acceptance message, where the registration acceptance message includes at least one of information of the extended paging message and paging configuration parameters of the extended paging message.

[0301] Optionally, in one embodiment of the present disclosure, when the AMF receives a registration request from an access network device, it can obtain a paging extension indication in the registration request. For example, the AMF can determine whether to support paging message extension based on local policies and / or network capabilities to determine whether to accept the registration request sent by the terminal.

[0302] Optionally, in one embodiment of the present disclosure, the information of the extended paging message may be, for example, used to indicate the capability of the AMF to extend the paging message.

[0303] Optionally, in one embodiment of the present disclosure, the paging configuration parameters may include, for example, paging extension information supported by a terminal, a time domain for monitoring at least one paging message, specific additional information included in any paging message, and paging message indication information. The paging message indication information may, for example, indicate multiple paging messages corresponding to an operation instruction. The paging extension information may, for example, indicate specific additional information included in paging messages supported by the terminal.

[0304] In the above embodiment, the AMF can determine whether to accept the registration request, which can improve the accuracy of the registration request acceptance and the accuracy of the message extension.

[0305] Step S3114: The AMF sends a Registration Accept Message in response to the registration request to the access network device, where the Registration Accept Message includes at least one of information about the extended paging message and paging configuration parameters of the extended paging message.

[0306] In one embodiment of the present disclosure, a paging configuration parameter may be used to receive at least one paging message. The paging message indication information in the paging configuration may, for example, indicate which paging messages correspond to the same operation instruction. The paging message indication information may, for example, be the bit value of a fixed bit position in at least one paging message. For example, whether at least one paging message corresponds to the same operation instruction may be determined based on the bit value of a fixed bit position in at least one paging message. For example, if the bit values ​​of a fixed bit position in at least one paging message are the same, it may be determined that the at least one paging message corresponds to the same operation instruction.

[0307] Step S3115: The access network device receives a registration accept message sent by the AMF in response to the registration request, wherein the registration accept message includes at least one of information of the extended paging message and paging configuration parameters of the extended paging message.

[0308] Step S3116: The access network device sends a registration acceptance message to the terminal, wherein the registration acceptance message includes at least one of information of the extended paging message and paging configuration parameters of the extended paging message;

[0309] Step S3117: The terminal receives a registration acceptance message sent by the access network device in response to the registration request, wherein the registration acceptance message includes at least one of information of the extended paging message and paging configuration parameters of the extended paging message;

[0310] Optionally, the registration accept message includes at least one of information about the extended paging message and paging configuration parameters for the extended paging message.
