Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular, to a communication method, device, and electronic device. Background Art

[0002] As an intermediate node of ambient internet of things (AIOT) devices, readers can aggregate and transmit asset inventory and read-write control commands of AIOT devices, so that core network devices can obtain data information of AIOT devices, or core network devices and servers can obtain data information of AIOT devices.

[0003] At present, in a related aggregation transmission method, the Reader will receive a request for data information for each AIOT device sent by the core network device. In this process, due to the large number of AIOT devices, the Reader will be frequently paging awakened by the core network device. In addition, since the Reader and AIOT devices are mobile, the Reader may be paging awakened again after just completing an AIOT data information report, which increases the power consumption of the Reader and affects the management of AIOT devices by the core network device. Summary of the invention

[0004] The present application provides a communication method, apparatus and electronic device, wherein a core network device can store a request for data information of an AIOT device and the remaining time for the first device to be in a connected state next time when the first device is in an idle state, thereby solving the problem in the related art that the first device is frequently paged and awakened by the core network device when in an idle state, and reducing the power consumption of the first device.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, a communication method is provided, which is applied to a core network device, and the method includes:

[0007] After receiving the first request, when the first device corresponding to the AIOT device is in the first state, the first information is stored, and when the first device is in the second state, a second request is sent to the first device, the first request is used to request data information of the AIOT device, the first information includes device information of the AIOT device and / or device information of the first device, the second request is used to request data information of the AIOT device, so that the first device obtains the data information of the AIOT device, the first state is used to indicate that no connection is established between the first device and the core network device, and the second state is used to indicate that a connection has been established between the first device and the core network device;

[0008] A first notification sent by a first device is received, where the first notification is used to indicate data information of the AIOT device.

[0009] Based on the method of the first aspect, after receiving the first request, the core network device determines the state of the first device. When the first device is in the first state, the core network device will store the first information, and after a certain period of time, determine the state of the first device again, and send a second request to the first device when the first device is in the second state. When the first device is in the second state, the core network device will immediately send the second request to the first device. After receiving the second request sent by the core network device, the first device performs an inventory of the AIOT device. The AIOT device reports its own data information to the first device according to the second request, thereby causing the first device to send the data information of the AIOT device to the core network device. As a result, the core network device only sends the second request to the first device when the first device is in the second state, thereby reducing the number of times the first device is awakened by paging from the core network device and reducing the power consumption of the first device.

[0010] In a possible implementation manner of the first aspect, the method further includes:

[0011] After receiving the first request, when the first device is in the second state, sending a second request to the first device.

[0012] Therefore, when the first device is in the second state, the core network device sends a second request to the first device, so that the first device queries the data information of the AIOT device according to the second request.

[0013] In a possible implementation manner of the first aspect, the method further includes:

[0014] Starting from storing the first information, after a first time period, it is determined that the first device is in the second state, the first time period is greater than or equal to the remaining time the first device will be in the second state next time, and the remaining time period is determined based on at least one of a predefined time period of the first state, a predefined time period of the second state, or a notification sent by the first device.

[0015] Therefore, the core network device can start from storing the first information, and after a first period of time, determine that the state of the first device is the second state, so that the core network device can determine that data can be forwarded to the first device, thereby avoiding the first device being awakened by paging when the first device is in the first state, thereby reducing the power consumption of the first device.

[0016] In a possible implementation manner of the first aspect, the first information further includes:

[0017] The remaining time that the first device will be in the second state next time and / or the first identifier, where the first identifier is used to indicate the state of the first device.

[0018] Therefore, the first information includes the remaining duration of the second state and / or the first identifier, so that the core network device can determine the state of the first device.

[0019] In a possible implementation manner of the first aspect, the method further includes:

[0020] According to the predefined time period of the first state and / or the predefined time period of the second state, the remaining time for the first device to be in the second state next time and the first identifier are updated.

[0021] Therefore, the core network device can determine the remaining time for the first device to be in the second state next time according to the predefined time period of the first state and / or the predefined time period of the second state, and then update the remaining time and the first identifier.

[0022] In a possible implementation manner of the first aspect, the method further includes:

[0023] receiving a second notification sent by the first device, where the second notification is used to indicate a startup timestamp when the first device enters the first state next time;

[0024] According to the second notification, the remaining time for the first device to be in the second state next time and the first identifier are updated.

[0025] Therefore, the first device sends a second notification to the core network device, so that the core network device determines the first identifier and the remaining time of the first device being in the second state next time according to the second notification, and then updates the remaining time of the first device being in the second state next time into the first information, so that the core network device determines the duration of the next time the second request can be sent to the first device, and then the core network device determines the state of the first device according to the second notification.

[0026] In a possible implementation manner of the first aspect, the core network device includes: a first network element; and the method specifically includes:

[0027] After receiving the first request, the first network element stores the first information when the first device is in the first state, and sends the second request to the first device when the first device is in the second state;

[0028] Alternatively, after receiving the first request, the first network element sends a second request to the first device when the first device is in the second state;

[0029] The first network element receives a first notification sent by the first device.

[0030] Thus, the core network device can send a second request to the first device through the first network element to request the data information of the AIOT device. In addition, the core network device can also receive the first notification sent by the first device through the first network element, so that the core network device obtains the data information of the AIOT device, or the core network device and the server obtain the data information of the AIOT device.

[0031] In a possible implementation manner of the first aspect, the method further specifically includes:

[0032] After receiving the first request, the first network element sends a second request to the first device when the first device is in the second state.

[0033] Therefore, the core network device sends the second request to the first device only when the first device is in the second state, thereby avoiding the first device being awakened by frequent paging when it is in the first state, and reducing the power consumption of the first device.

[0034] In a possible implementation manner of the first aspect, the core network device further includes: a second network element; and the method further includes:

[0035] The first network element sends a second request to the first device, including:

[0036] The first network element sends a second request to the second network element, so that the second network element sends a third request to the first device, where the third request is used to request data information of the AIOT device;

[0037] The first network element receives a first notification sent by a first device, including: the first network element receives a third notification sent by a second network element, the third notification is used to indicate data information of the AIOT device, and the third notification is sent by the second network element after receiving the first notification sent by the first device.

[0038] Thus, the first network element can send a second request to the first device through the second network element to request data information of the AIOT device. In addition, the first network element can receive the first notification sent by the first device through the second network element, so that the first network element receives the data information of the AIOT device.

[0039] In a possible implementation manner of the first aspect, the method further includes:

[0040] The first network element receives a fourth notification sent by the second network element, where the fourth notification is used to indicate a startup timestamp when the first device is in the first state, and the fourth notification is sent by the second network element after receiving the second notification sent by the first device, where the fourth notification is used to indicate a startup timestamp when the first device enters the first state next time;

[0041] The first network element determines the remaining time for the first device to be in the second state next time according to the startup timestamp of the first device entering the first state next time, and stores the remaining time for the first device to be in the second state next time in the first information.

[0042] Therefore, the second network element sends a fourth notification to the first network element, so that the first network element determines the remaining time of the first device being in the second state next time according to the fourth notification, and then updates the remaining time of the first device being in the second state next time into the first information, so that the core network device determines the remaining time of sending a request to the first device next time.

[0043] In a possible implementation manner of the first aspect, the core network device further includes a second network element, a third network element, and a fourth network element; and the method further includes:

[0044] The first network element receives a first request sent by the third network element;

[0045] The first network element sends a fourth request to the fourth network element, where the fourth request is used to query the first device corresponding to the AIOT device;

[0046] The first network element receives a fifth notification sent by the fourth network element, where the fifth notification is used to indicate an identifier of the first device;

[0047] The first network element sends a fifth request to the second network element, where the fifth request is used to query the state of the first device;

[0048] The first network element receives a sixth notification sent by the second network element, where the sixth notification is used to indicate whether the first device is in the first state or the second state, and a remaining time for the first device to be in the second state next time.

[0049] Thus, the first network element receives the first request sent by the third network element, and the first network element sends a fourth request to the fourth network element according to the device information of the AIOT device in the first request, and then receives the identifier of the first device corresponding to the AIOT device sent by the fourth network element. The first network element sends a fifth request to the second network element according to the identifier of the first device, and then receives the state of the first device and the remaining time for the first device to be in the second state next time sent by the second network element, so that the first network element determines whether to send the second request immediately or cache the device information of the AIOT device according to the state of the first device, thereby avoiding the first device being awakened by frequent paging.

[0050] In a possible implementation manner of the first aspect, the method further includes:

[0051] The first network element starts by storing the first information and, after a first time period, determines that the first device is in the second state, the first time period being greater than or equal to a remaining time that the first device will be in the second state next time, and the remaining time is determined based on at least one of a predefined time period of the first state, a predefined time period of the second state, or a notification sent by the first device.

[0052] Therefore, the first network element starts from storing the first information and, after the first period of time, determines that the state of the first device is the second state, thereby enabling the first network element to determine that data can be forwarded to the first device, thereby avoiding the first device being awakened by paging when the first device is in the first state, thereby reducing the power consumption of the first device.

[0053] In a possible implementation manner of the first aspect, the method further includes:

[0054] The first network element sends a sixth request to the second network element after a first time period starting from storing the first information, where the sixth request is used to query the state of the first device, the first time period is greater than or equal to a predefined remaining time for the first device to be in the second state next time, and the remaining time period is determined according to at least one of a predefined time period of the first state, a predefined time period of the second state, or a notification sent by the first device;

[0055] The first network element receives a seventh notification sent by the second network element, where the seventh notification is used to indicate that the state of the first device is the first state or the second state;

[0056] The first network element determines, according to the seventh notification, whether the state of the first device is the second state.

[0057] Therefore, when the first device is in the first state, the first network element can send the sixth request to the second network element after the first period of time, and then receive the seventh notification sent by the second network element, so that the first network element determines the state of the first device again according to the seventh notification, thereby ensuring the accuracy of the state of the first device.

[0058] In a possible implementation manner of the first aspect, after the first network element receives the first notification sent by the first device, the method further includes:

[0059] The first network element sends an eighth notification to the third network element, where the eighth notification is used to indicate data information of the AIOT device.

[0060] Therefore, the first network element sends the eighth notification to the third network element, so that the third network element obtains the data information of the AIOT device, thereby facilitating the core network device or server to manage the AIOT device.

In other embodiments, the first device includes a UE and a RAN, the second network element communicates with the RAN through the N2 interface, and the RAN communicates with the UE.

[0110] It should be understood that Figure 2 The types and quantities of network elements of the core network device shown are only an exemplary description, and the core network device may also include other network elements ( Figure 2 (not shown in the figure), the number of the first network element, the second network element, the third network element, the fourth network element, the fifth network element or the sixth network element may be multiple, which is not limited in the embodiments of the present application.

[0111] The first network element may be responsible for managing the network data open to the outside by the core network device. The first network element may be located between the network elements of the server and the core network device, thereby ensuring that the server can securely access the core network device. The first network element may also be located between different network elements of the core network device, which is not limited in the embodiments of the present application. In some embodiments, the first network element may be a network exposure function (NEF). In other embodiments, the first network element may be an ambient internet of things-controller (AIOT-C). Among them, AIOT-C may be set in the core network device separately from NEF, or may be integrated in NEF, which is not limited in the embodiments of the present application.

[0112] The second network element may be responsible for the access and mobility management of the first device in the mobile network, for example, the registration management of the first device. In some embodiments, the second network element may be an access and mobility management function (AMF). In other embodiments, the second network element may be an ambient internet of things-function (AIOT-F). Among them, AIOT-F may be set separately from AMF in the core network device, or may be integrated in AMF, which is not limited in the embodiments of the present application.

[0113] The third network element may receive a request sent by the server to the core network device, and the third network element may also send data of the core network device to the server. In some embodiments, the third network element may be an application function (AF).

[0114] The fourth network element can be used as a database of user data to provide users with services such as user authentication, user identification, access authorization, registration, mobility, subscription, and SMS management. For example, the fourth network element can store the user's account opening data and contract data. In some embodiments, the fourth network element can be a unified data management function (UDM).

[0115] The fifth network element is used to register and obtain relevant information of the network function. In some embodiments, the fifth network element may be a network repository function (NRF).

[0116] The sixth network element may process the user's authentication data, and the sixth network element may also provide user authentication and authorization services to other network elements. In some embodiments, the sixth network element may be an authentication server function (AUSF).

[0117] It should be understood that the above network elements are all network elements in the existing communication network. The above network elements may also be other network elements with corresponding functions. The embodiment of the present application only makes a brief introduction to this, and the functions and applications of the above network elements are not limited to this.

[0118] Based on the three possible situations of the first device, the topological structure between the AIOT device, the first device and the core network device is described in detail. In addition, the core network device may have multiple second network elements, and the embodiment of the present application takes a second network element in the core network device as an example for detailed description.

[0119] See also Figure 3 , Figure 4 and Figure 5 , Figure 3 , Figure 4 and Figure 5 A topological structure diagram between an AIOT device, a first device and a core network device provided in an embodiment of the present application.

[0120] In one possible topology, such as Figure 3 As shown, taking the first device as a UE as an example, the second network element can be associated with multiple UEs, and each UE can be associated with multiple AIOT devices.

[0121] In another possible topology, such as Figure 4 As shown, taking the first device being A-RAN as an example, the second network element can be associated with multiple A-RANs, and each A-RAN can be associated with multiple AIOT devices.

[0122] In another possible topology, such as Figure 5 As shown, the first device may include an A-RAN and a UE, the second network element may be associated with multiple A-RANs, each A-RAN may be associated with multiple UEs, and each UE may be associated with multiple AIOT devices.

[0123] It should be understood that Figure 3 , Figure 4 and Figure 5 The topological structure shown is only an example description, and the embodiments of the present application are not limited thereto. Figure 3 , Figure 4 and Figure 5 The number of AIOT devices, the number of first devices, or the number of second network elements in the core network device shown are merely exemplary descriptions, and the embodiments of the present application are not limited thereto.

[0124] In summary, the first device and the AIOT device can be in a many-to-many association relationship. The core network device can be associated with multiple first devices, and the first device can be associated with multiple AIOT devices. When the core network device receives a request for an AIOT device, the core network device will send the request to the first device associated with the AIOT device. At this time, the first device will receive a request sent by the core network device. When the core network device receives multiple requests for AIOT devices, since the first device is associated with multiple AIOT devices, at this time, the first device will receive multiple requests sent by the core network device.

[0125] In the case where the core network device requests the data information of the AIOT device, the first device may be paged and awakened once for each request, causing the first device to switch from an idle state (Idle state) to a connected state (Connected state). Since the number of AIOT devices associated with the first device is large, the first device will receive requests for each AIOT device sent by the core network device, that is, multiple requests, so that the first device may be frequently paged and awakened by the core network device. In addition, when the first device or the AIOT device moves, the first device may be paged and awakened again by the core network device just after reporting the data information of the AIOT device once. Both of the above situations may increase the power consumption of the first device and affect the management of the AIOT device by the core network device or the server.

[0126] Based on the above description, an embodiment of the present application proposes a communication method. The core network device can reduce the frequent paging wake-up of the first device by judging the state of the first device, thereby reducing the power consumption of the first device. Among them, the type of state of the first device may include a connected state, an idle state, a non-network access state, or a subclass of the idle state, such as a deactivated state, which is not limited in the embodiment of the present application.

[0127] Below, the embodiment of the present application will be described with Figures 1 to 5 Taking the AIOT device, the first device and the core network device of the shown structure as an example, the communication method provided in the embodiment of the present application is explained in detail in combination with the accompanying drawings and application scenarios.

[0128] See also Figure 6 , Figure 6 A signaling interaction diagram of a communication method provided in an embodiment of the present application. Figure 6 As shown, a communication method provided in an embodiment of the present application may include:

[0129] S101. A core network device receives a first request.

[0130] The first request is used to request data information of the AIOT device.

[0131] The first request may be a request initiated by a network element within the core network device, or may be a request initiated by a server, which is not limited in the embodiments of the present application.

[0132] It should be understood that the first request can be sent in a data packet, or in a message or instruction. The embodiment of the present application does not limit the sending form of the first request.

[0133] After receiving the first request, the core network device determines the state of the first device. When the first device is in the first state, S102 is executed, and when the first device is in the second state, S103 is executed.

[0134] S102. The core network device stores first information when the first device corresponding to the AIOT device is in a first state, and sends a second request to the first device when the first device is in a second state.

[0135] Correspondingly, the first device receives the second request sent by the core network device.

[0136] S103. When the first device is in the second state, the core network device sends a second request to the first device.

[0137] Correspondingly, the first device receives the second request sent by the core network device.

[0138] It should be understood that when the core network device sends the second request to the first device, the core network device may also store the first information.

[0139] Among them, the first information includes device information of the AIOT device and / or device information of the first device, the second request is used to request data information of the AIOT device so that the first device obtains the data information of the AIOT device, the first state is used to indicate that no connection is established between the first device and the core network device, and the second state is used to indicate that a connection has been established between the first device and the core network device.

[0140] It should be understood that S102 and S103 are two parallel schemes in the communication method provided in the embodiment of the present application.

[0141] Among them, the AIOT device corresponding to the first device may be multiple AIOT devices associated with multiple first devices, multiple AIOT devices associated with one first device, or one AIOT device associated with one first device, which is not limited in the embodiments of the present application.

[0142] When the first device is in the first state, no connection is established between the first device and the core network device. In some embodiments, the first state may be an idle state, or a subclass of the idle state, such as a deactivated state. In other embodiments, the first state may be a network-unconnected state, which is not limited in the embodiments of the present application.

[0143] When the first device is in the second state, a connection has been established between the first device and the core network device. In some embodiments, the second state may be a connected state.

[0144] The first information includes device information of the AIOT device and / or device information of the first device.

[0145] Among them, the device information of the AIOT device may include an identity document (ID) of the AIOT device, which is used to uniquely indicate the AIOT device. The device information of the AIOT device may also include any one or more of the group ID of the AIOT device or the type of the AIOT device. The device information of the AIOT device may also include other information, which is not limited to the embodiments of the present application.

[0146] The device information of the first device may include an identifier of the first device, which is used to uniquely indicate the first device. The device information of the first device may also include other information, which is not limited in the embodiment of the present application.

[0147] It should be understood that the first information may not include the device information of the first device, and the device information of the first device can be queried and obtained based on the device information of the AIOT device.

[0148] The first information may also include a remaining time that the first device will be in the second state next time and / or a first identifier.

[0149] The first identifier is used to indicate the state of the first device. In some embodiments, the first identifier is the first state. In other embodiments, the first identifier is the second state. The first identifier can also be represented by a state synchronization bit. For example, if the state synchronization bit is 0, it can represent the first state, and if the state synchronization bit is 1, it can represent the second state. This embodiment of the application does not limit this.

[0150] The remaining duration and the first identifier are determined according to at least one of a predefined period of the first state, a predefined period of the second state, or a notification sent by the first device. The predefined period is characterized by a predefined period, a start time, and / or an end time. The predefined period may be the sum of the duration of the first device being in the first state and the duration of the first device being in the second state.

[0151] It should be understood that, in addition to being stored in the first network element, the first identifier may also be stored in the second network element, and this embodiment of the present application does not limit this.

[0152] The second request is used to request data information of the AIOT device, and the second request may include external area information of the AIOT device and device information of the AIOT device.

[0153] Among them, the external area information of the AIOT device refers to the geographical location information of the AIOT device. The geographical location information can be information of a specific location, or it can be location information of a certain range. In some embodiments, the regional information of the AIOT device can be represented by longitude coordinates and latitude coordinates, for example, the regional information of the AIOT device is 30 degrees north latitude and 10 degrees east latitude. In other embodiments, the regional information of the AIOT device can be represented by a longitude coordinate range and a latitude coordinate range, for example, the regional information of the AIOT device is the location range of 30 degrees north latitude to 50 degrees north latitude, 10 degrees east latitude to 30 degrees east latitude. In other embodiments, the regional information of the AIOT device can indicate a specific location or a specific range through information negotiated in advance, for example, the regional information of the AIOT device is the eighth region, and the eighth region is a predefined location range of 30 degrees north latitude to 50 degrees north latitude, 10 degrees east latitude to 30 degrees east latitude.

[0154] The second request may also include inventory policy information of the AIOT device.

[0155] The inventory policy information may be used to instruct the first device to periodically perform inventory. In some embodiments, the inventory policy information of the AIOT device may be the frequency at which the first device periodically performs inventory. In other embodiments, the inventory policy information of the AIOT device may be the cycle at which the first device periodically performs inventory.

[0156] The inventory policy information of the AIOT device can also be used to indicate whether all AIOT devices need to report data information. In some embodiments, the inventory policy information of the AIOT device can indicate that all AIOT devices need to report data information. In other embodiments, the inventory policy information of the AIOT device can indicate that AIOT devices that have not yet performed inventory reporting need to report data information, for example, newly added AIOT devices associated with the first device need to report data information.

[0157] The second request may also include report aggregation information of the AIOT device.

[0158] Among them, the report aggregation information is used to indicate whether the first device needs to aggregate the report within a specific aggregation period, and whether the first device needs to report the ID of the AIOT device to the core network device after the aggregation period.

[0159] It should be understood that the inventory policy information and the report aggregation information may or may not be carried in the second request. When the second request does not include the inventory policy information and / or the report aggregation information, the AIOT device may report data information according to the predefined inventory policy information and / or the report aggregation information.

[0160] The second request may also include location indication information to indicate whether the core network device requests to provide the location information of the AIOT device. When the location indication information indicates that the core network device requests to provide the location information of the AIOT device, the AIOT device needs to report the specific location information of the AIOT device. When the location indication information indicates that the core network device does not need to request to provide the location information of the AIOT device, the AIOT device does not need to report the specific location information of the AIOT device. It should be understood that when the second request does not include the location indication information, the AIOT device does not need to report the specific location information of the AIOT device.

[0161] It should be understood that the second request can be sent in a data packet, or in a message or instruction. The embodiment of the present application does not limit the sending form of the second request.

[0162] In summary, the core network device sends a second request to the first device when the first device is in the second state, so that the first device obtains data information of the AIOT device. When the first device is in the first state, the core network device stores the first information, and when the first device is in the second state, the core network device sends a second request to the first device, thereby reducing the frequent awakening of the first device in the first state and reducing the power consumption of the first device.

[0163] S104. The first device sends a first notification to the core network device.

[0164] Correspondingly, the core network device receives the first notification sent by the first device.

[0165] The first notification is used to indicate data information of the AIOT device.

[0166] If the core network device allows and the second request includes the location information of the requested AIOT device, the first notification may also include the location information of the AIOT device, so that the core network device obtains the specific location of the AIOT device.

[0167] The first notification may further include end indication information, which is used to indicate whether the current inventory notification is the last inventory notification of this round of inventory.

[0168] It should be understood that the first notification can be sent in a data packet, or in a message or instruction, and the present embodiment of the application does not limit the sending form of the first notification. In addition, the notification mentioned in the embodiment of the present application can also be a response or content, and the present embodiment of the application does not limit this.

[0169] In summary, the first device sends a first notification to the core network device, so that the core network device obtains the data information of the AIOT device, or the core network device and the server obtain the data information of the AIOT device, thereby facilitating the core network device or the server to manage the AIOT device.

[0170] In the communication method provided by the embodiment of the present application, after receiving the first request, the core network device determines the state of the first device. When the first device is in the first state, the core network device will store the first information, and after a certain period of time, determine the state of the first device again, and send a second request to the first device when the first device is in the second state. When the first device is in the second state, the core network device will immediately send the second request to the first device without determining the state of the first device again. After receiving the second request sent by the core network device, the first device performs an inventory count of the AIOT device. The AIOT device reports its own data information to the first device according to the second request, thereby causing the first device to send the data information of the AIOT device to the core network device. As a result, the core network device sends the second request to the first device only when the first device is in the second state, thereby reducing the number of times the first device is awakened by paging from the core network device and reducing the power consumption of the first device.

[0171] Based on the above embodiment, the core network device may store the first information in the form of a flow table or in other forms, which is not limited in the embodiment of the present application.

[0172] See also Figure 7 , Figure 7 A flow table structure diagram provided in an embodiment of the present application. Figure 7 As shown, the flow table structure provided in the embodiment of the present application may include a header and data, and the core network device may manage the forwarding of request data and the caching of request data according to the state of the first device in the flow table. Among them, the destination (Destination) is the header of the flow table, and data 1, data 2, and data 3 are the data of the flow table. The user plane function (UPF) is identified as the device information of the first device, which is used for the first device to identify which core network device's UPF sends the data to it. Downlink data 1, downlink data 2, and downlink data 3 are the device information of the AIOT device.

[0173] The flow table may also include a cache expiration timer (Cache Expire Timer), and the value of the cache expiration timer is the value of the periodic update timer (Periodic Update Timer) minus the value of the current timer (Cur Timer for short). The value of the cache expiration timer is updated in real time. When the cache expiration timer expires, the core network device may send downlink data 1, downlink data 2, and downlink data 3 cached in the flow table to the first device. It should be understood that the core network device may also send the value of the cache expiration timer in the flow table to the first device, and the embodiments of the present application do not limit this. In addition, the number or type of timers shown in the flow table is only an exemplary description. The flow table may also include only one timer to indicate the remaining duration of the first device being in the second state next time, and the embodiments of the present application do not limit this.

[0174] When the cache expiration timer expires, the core network device may also re-query the state of the first device, and update the state of the first device and the timer information in the flow table according to the query result.

[0175] It should be understood that Figure 7 The flow table structure shown is only an exemplary description, and the flow table may also include other headers or data, which is not limited in the embodiments of the present application. In some embodiments, the flow table may also include a first identifier. When the flow table is initialized, the flow table does not obtain the state of the first device. At this time, the state of the first device is unknown. After the flow table obtains the state of the first device, the first identifier is updated to the first state or the second state.

[0176] When the core network device determines that the first device is in the first state, after a certain period of time, it is necessary to determine the state of the first device again. At this time, the core network device can determine the state of the first device based on at least one of the remaining time of the first device being in the second state next time, the first identifier, the historical notification sent by the first device before the core network device sends the second request to the first device, the predefined time period of the first state, or the predefined time period of the second state.

[0177] When the core network device determines that the first device is in the second state, the core network device may send a second request to the first device.

[0178] It can be seen that after receiving the first request, the core network device will determine whether the state of the first device is the first state or the second state. When the first device is in the first state, the core network device will determine the state of the first device again before sending the second request, that is, the core network device will determine the state of the first device twice, thereby ensuring the accuracy of the state of the first device queried by the core network device. It should be understood that the operation of determining the state of the first device for the second time is optional, and the embodiments of the present application do not limit this.

[0179] The remaining time that the first device is in the second state next time and the first identifier are updated according to the predefined time period of the first state or the predefined time period of the second state or the notification sent by the first device.

[0180] Based on the above description, the core network device can determine that the first device is in the second state after the first time period has passed since the first information was stored. The first time period is greater than or equal to the remaining time for the first device to be in the second state next time, and the remaining time period is determined based on at least one of a predefined time period of the first state, a predefined time period of the second state, or a notification sent by the first device.

[0181] Among them, the first duration is the duration of N time slots after the first device switches from the first state to the second state, N is greater than or equal to zero, and the first duration is greater than or equal to the remaining duration of the first device being in the second state next time.

[0182] In summary, the core network device can start from storing the first information, and after a first period of time, determine that the state of the first device is the second state, so that the core network device determines that data can be forwarded to the first device, thereby avoiding the first device being frequently paging and awakened when the first device is in the first state, thereby reducing the power consumption of the first device.

[0183] Based on the above description, the core network device can update the remaining time and the first identifier of the first device in the second state next time through the second notification or the historical notification. The second notification is used to indicate the start timestamp of the first device entering the first state next time.

[0184] Among them, the second notification is sent after the core network device receives the first notification sent by the first device, and the historical notification is the historical notification sent by the first device before the core network device receives the first request described above, or the historical notification sent by the first device before the core network device sends the second request to the first device. The embodiment of the present application does not limit this.

[0185] Among them, the startup timestamp is the time when the first device enters the first state next time, and the core network device can update the remaining time and the first identifier of the first device being in the second state next time according to the startup timestamp.

[0186] In some embodiments, the core network device receives the second notification sent by the first device, and updates or creates the first identifier as the first state, and updates the first identifier as the second state after the remaining time for the first device to be in the second state next time. In other embodiments, the core network device may update or create the first identifier based on the remaining time for the first device to be in the second state next time, and when the first identifier is in the first state, the core network device updates the first identifier as the second state after the remaining time for the first device to be in the second state next time.

[0187] It should be understood that the second notification can be sent in a data packet, or in a message or instruction. The embodiment of the present application does not limit the sending form of the second notification.

[0188] In summary, the first device sends a second notification to the core network device, so that the core network device determines the first identifier and the remaining time of the first device being in the second state next time according to the second notification, and then updates the remaining time of the first device being in the second state next time into the first information, so that the core network device determines the next time when the second request can be sent to the first device, and then the core network device determines the state of the first device according to the second notification.

[0189] In a specific embodiment, in combination Figure 6 , taking the first network element in the core network device as the main body, the specific process of the communication method of the embodiment of the present application is introduced in detail.

[0190] See also Figure 8 , Figure 8 A flow chart of a communication method provided in an embodiment of the present application. Figure 8 As shown, a communication method provided in an embodiment of the present application may include:

[0191] S201. After receiving a first request, the first network element stores first information when the first device is in a first state, and sends a second request to the first device when the first device is in a second state.

[0192] S202: After receiving the first request, the first network element sends a second request to the first device when the first device is in the second state.

[0193] S203. The first network element receives a first notification sent by the first device.

[0194] In summary, the core network device can send a second request to the first device through the first network element, and the second request is used to request data information of the AIOT device. In addition, the first network element can also receive the first notification sent by the first device, so that the core network device obtains the data information of the AIOT device, or the core network device and the server obtain the data information of the AIOT device.

[0195] Based on the above embodiment, the first network element may also determine that the first device is in the second state after a first period of time has passed since the first information was stored.

[0196] The first duration is greater than or equal to the remaining duration of the first device being in the second state next time, and the remaining duration is determined based on at least one of a predefined time period of the first state, a predefined time period of the second state, or a notification sent by the first device.

[0197] In summary, the first network element starts from storing the first information and after a first period of time, determines that the first device is in the second state, and further determines that a connection has been established between the first device and the core network device, and the core network device can send a request to the first device.

[0198] In a specific embodiment, in combination Figure 6 and Figure 8 , taking the first network element, the second network element, the third network element, the fourth network element, the fifth network element and the sixth network element in the core network device as an example, the specific implementation process of the communication method of the embodiment of the present application is described in detail.

[0199] A communication method provided in an embodiment of the present application can be described in three stages, namely, stage 1, stage 2, and stage 3. In stage 1, a process is described in which a first network element queries a second network element corresponding to an AIOT device; in stage 2, a process is described in which a first network element queries the state of a first device corresponding to an AIOT device, and then sends a second request to the first device; in stage 3, a process is described in which an AIOT device sends data information of the AIOT device to a third network element via the first device.

[0200] Next, combine Figures 9 to 11 , which introduces the specific implementation process of phase one, phase two and phase three respectively.

[0201] See also Fig. 9 , Fig. 9 This is a signaling interaction diagram of another communication method provided in an embodiment of the present application. Fig. 9 As shown, in stage one, the core network device may include a first network element, a third network element, and a fifth network element. A communication method provided in an embodiment of the present application may include:

[0202] S301. The third network element sends a first request to the first network element.

[0203] Correspondingly, the first network element receives the first request sent by the third network element.

[0204] S302: The first network element authorizes the first request and performs a zone conversion of the AIOT device.

[0205] Among them, the first network element authorizes the first request, that is, the first network element determines which requests in the first requests sent by the third network element can request data information of the AIOT device and which requests cannot request data information of the AIOT device.

[0206] Among them, the regional conversion of the AIOT device, that is, the first network element translates the external regional information of the AIOT device into internal regional information, and the internal regional information is the geographical location information predefined inside the core network device that is different from the external regional representation. In some embodiments, the internal regional information can be the tracking area code (TAC) of the core network device, and the core network device can determine the specific location information of the AIOT device through the tracking area code. The embodiment of the present application does not limit the form of the internal regional information.

[0207] S303. The first network element sends a query request to the fifth network element.

[0208] Correspondingly, the fifth network element receives the query request sent by the first network element.

[0209] The query request includes the internal area information of the AIOT device, and the query request is used to query the second network element corresponding to the AIOT device.

[0210] It should be understood that the query request can be sent in a data packet, or in a message or instruction. The embodiment of the present application does not limit the form in which the query request is sent.

[0211] S304. The fifth network element sends a query notification to the first network element.
