[0089] Optionally, the method of the embodiment of the present application can be applied to the power-generating Internet of Things.

[0090] Figure 2 This is one of the flow charts of the Internet of Things communication method provided in the embodiment of the present application, such as Figure 2 As shown, the embodiment of the application provides an Internet of Things communication method, the execution subject of which can be an Internet of Things intermediate node. The method includes:

[0091] Step 201: Select a cell that supports access to an IoT intermediate node based on the first information;

[0092] The first information includes at least one of the following: system information of the cell, first pre-configuration information of the IoT intermediate node, and first configuration information downloaded from the server.

[0093] Specifically, according to at least one item of the first information, a cell supporting access of an IoT intermediate node is selected for access, so that access to the network as an IoT intermediate node can be achieved.

[0094] For example, reading the indication information of whether the cell supports the IoT intermediate node in the system information (SI) of the cell, and selecting the cell that supports the IoT intermediate node to reside in and access; or

[0095] Selecting a cell to access based on a list of cells allowed to be accessed that is pre-configured to the intermediate node; or

[0096] The intermediate node first selects a cell and accesses the network as an ordinary terminal, and downloads the relevant configuration information required for its work as an intermediate node, for example, at least including the cell list information supporting the IoT intermediate node, and then selects the cell supporting the IoT intermediate node to access.

[0097] Optionally, the first configuration information is downloaded from a server through a user plane, for example.

[0098] The IoT communication method of this embodiment selects a cell access that supports IoT intermediate node access based on first information; the first information includes at least one of the following: system information of the cell, first pre-configuration information of the IoT intermediate node, and first configuration information downloaded from a server. The IoT intermediate node can select a cell access that supports IoT intermediate node access based on a variety of methods, which is more flexible and realizes the process of accessing the network as an IoT intermediate node.

[0099] Optionally, the system information of the cell includes: second indication information of whether access by the IoT intermediate node is allowed;

[0100] The first pre-configuration information includes at least one of the following: information about at least one cell that the IoT intermediate node is allowed to access, and information about cells that support the IoT intermediate node;

[0101] The first configuration information includes: information about cells that the IoT intermediate node is allowed to access. Optionally, the cell information can be represented by at least one of the following: frequency, physical cell identifier (PCI), and cell global identifier (CGI).

[0102] For example, a common terminal accesses a cell that supports enabling an IoT intermediate node:

[0103] For ordinary terminals, during the cell selection and reselection process, there is no need to consider whether the System Information Block (SIB) includes indication information supporting IoT intermediate node access. They reside in the appropriate cell according to the conventional (legacy) cell selection and reselection mechanism and initiate services on demand.

[0104] For example, the cell selection of the IoT intermediate node (based on signaling (such as information in the system information SI)):

[0105] After the IoT intermediate node is powered on, it selects a cell as a terminal.

[0106] The access network device broadcasts indication information of whether it supports access of IoT intermediate nodes in the system information of the cell. The IoT intermediate nodes only select cells that allow IoT intermediate nodes to access to reside.

[0107] Exemplarily, cell selection of an IoT intermediate node (based on pre-configured / stored configuration):

[0108] The IoT intermediate node pre-configures / stores a list of cells that support IoT intermediate node access;

[0109] After the IoT intermediate node is powered on, it selects a cell as a terminal, selects a cell from the pre-configured cell list, and resides in it.

[0110] For example, the cell selection of the IoT intermediate node (based on the configuration information downloaded from the user plane):

[0111] After the IoT intermediate node is powered on, it first selects and accesses a cell as a normal terminal, establishes a packet data unit (PDU) session, and downloads relevant configuration information for its operation as an IoT intermediate node from the relevant server, which at least includes the cell information (information of one or more cells) that can be accessed as an IoT intermediate node.

[0112] The IoT intermediate node then selects a cell to reside in and initiates access based on the downloaded cell information supporting IoT intermediate node access.

[0113] Optionally, after step 201, the method further includes:

[0114] First indication information is sent to the access network device, where the first indication information is used to indicate that the node is an IoT intermediate node.

[0115] Specifically, in order to implement configuration and management of the IoT intermediate node, the IoT intermediate node, after selecting a cell to access, sends first indication information to the access network device to indicate to the access network device that the node is an IoT intermediate node.

[0116] Optionally, the method further includes:

[0117] Receive second configuration information sent by the access network device, where the second configuration information includes at least one of the following: a transmitting and receiving frequency, a bandwidth, a power, and a coverage area.

[0118] Optionally, the transceiver frequency is the transceiver frequency used for communication between the IoT intermediate node and the IoT terminal, the bandwidth is the bandwidth used for communication between the IoT intermediate node and the IoT terminal, the power is the power used for communication between the IoT intermediate node and the IoT terminal, and the coverage area is the coverage area of the IoT intermediate node.

[0119] Specifically, after accessing the cell, if the access network device determines to authorize the node as an IoT intermediate node, the second configuration information is sent to the node.

[0120] In the above implementation, the second configuration information is sent through the access network device to implement configuration of the IoT intermediate node.

[0121] Optionally, the method further includes:

[0122] communicating with the IoT terminal according to the second information;

[0123] The second information includes at least one of the following:

[0124] The second pre-configuration information of the Internet of Things intermediate node, the second configuration information, and the third configuration information downloaded from the server.

[0125] Specifically, after obtaining authorization, the IoT intermediate node communicates with the IoT terminal based on the second information, such as communicating with the IoT terminal based on information pre-configured to the IoT device. The information pre-configured to the IoT device includes, for example, at least one of the following: the transceiver frequency used for communication with the IoT terminal, the bandwidth used for communication with the IoT terminal, the power used for communication with the IoT terminal, and the coverage area of the IoT intermediate node.

[0126] Alternatively, the IoT intermediate node can download configuration information of relevant parameters from a server based on the user plane. For example, the configuration information includes at least one of the following: the transmit and receive frequency used for communication with the IoT terminal, the bandwidth used for communication with the IoT terminal, the power used for communication with the IoT terminal, and the coverage area of the IoT intermediate node. The IoT intermediate node then communicates with the IoT terminal based on the downloaded configuration information of relevant parameters.

[0127] Alternatively, the IoT intermediate node may communicate with the IoT terminal based on the second configuration information sent by the access network device.

[0128] For example, the configuration and configuration update of the IoT intermediate node:

[0129] There are several ways to configure IoT intermediate nodes:

[0130] 1. The relevant operating parameters of the IoT intermediate node may be pre-configured, for example, pre-configured to the IoT intermediate node before the IoT intermediate node leaves the factory, or pre-configured to the IoT intermediate node before the IoT intermediate node joins the network;

[0131] 2. The relevant working parameters of the IoT intermediate node can be configured by Operation Administration and Maintenance (OAM). For example, the IoT intermediate node downloads the OAM configuration information through its own user plane;

[0132] 3. The relevant working parameters of the IoT intermediate node can be configured by the access network device, for example, through air interface signaling between the IoT intermediate node and the access network device, such as configuration information of parameters carried in system information.

[0133] 4. Combination of the above methods 1-3, for example, pre-configuring some information and configuring other information through signaling from the access network device;

[0134] 5. Access network devices can update the configuration information of IoT intermediate nodes through signaling.

[0135] In the above implementation, the configuration of the IoT intermediate nodes is achieved through multiple means, which has low complexity and high flexibility.

[0136] Optionally, the method further includes:

[0137] Receive fourth indication information sent by the access network device, where the fourth indication information is used to instruct the Internet of Things intermediate node to stop service; the fourth indication information is sent by the access network device after receiving authorization change indication information sent by the core network device, and the authorization change indication information is used to instruct the Internet of Things intermediate node to change from authorization to non-authorization.

[0138] Specifically, the authorization information may change. For example, when an IoT intermediate node switches across base stations, the core network device may re-provide authorization information, such as changing authorization to non-authorization.

[0139] Optionally, the authorization change indication information may also be that the IoT intermediate node is changed from unauthorized to authorized.

[0140] For example, when the IoT intermediate node changes from authorized to unauthorized, the access network device must stop the relevant services of the IoT intermediate node, such as sending an instruction message to stop the service to the IoT intermediate node. When the IoT intermediate node changes from unauthorized to authorized, the access network device sends an instruction message to start / restart the service.

[0141] Optionally, the method further includes:

[0142] Receive third indication information sent by the network device, where the third indication information is used to instruct the Internet of Things intermediate node to at least one of the following: stop the service of the Internet of Things intermediate node, start the service of the Internet of Things intermediate node, and restore the service of the Internet of Things intermediate node.

[0143] Optionally, the method further includes:

[0144] When the working state of the Internet of Things intermediate node is abnormal, a Radio Resource Control (RRC) connection of the Internet of Things intermediate node is released.

[0145] For example, the shutdown and startup of an IoT intermediate node:

[0146] In order to flexibly control the intermediate nodes of the Internet of Things, and also considering factors such as power control, it may be necessary to flexibly control the shutdown and start-up of the intermediate nodes of the Internet of Things.

[0147] 1. Network equipment (such as base stations / core network equipment) can stop the service of the IoT intermediate node through signaling (such as through terminal context release, RRC connection release), or notify the IoT intermediate node to start / resume service through signaling (such as paging).

[0148] 2. The IoT intermediate node can also request to stop the service through the identity of a normal terminal (for example, executing the shutdown / deregistration process as a terminal).

[0149] 3. Support manual start or stop of IoT intermediate node services, for example, manually shut down or restart a IoT intermediate node.

[0150] 4. When the working status of the IoT intermediate node is abnormal, the RRC connection of the IoT intermediate node can be released locally. If necessary, the network can be accessed again, the above authorization and configuration work can be completed, and the service can be restarted.

[0151] Figure 3 This is one of the flow charts of the Internet of Things communication method provided in the embodiment of the present application, such as Figure 3 As shown, the embodiment of the application provides an Internet of Things communication method, the execution subject of which can be an access network device, such as a base station. The method includes:

[0152] Step 301: Receive first indication information sent by an IoT intermediate node, where the first indication information is used to indicate that the node is an IoT intermediate node;

[0153] Step 302: Send second indication information to the core network device, where the second indication information is used to indicate that the node is an IoT intermediate node;

[0154] Step 303: Receive authorization information sent by the core network device, where the authorization information is used to indicate whether the node is authorized as an IoT intermediate node.

[0155] For example, during or after access, the IoT intermediate node indicates to the access network device that the node's device type is an IoT intermediate node. The device type can be carried in RRC signaling, MAC-CE, or physical layer indication information.

[0156] The access network device sends second indication information to the core network device, which is used to indicate that the node is an IoT intermediate node.

[0157] The core network device determines whether to authorize the IoT intermediate node based on the second indication information of whether the node of the access network device is an IoT intermediate node, the contract information of the node, and at least one of the capability information of the node, and sends the authorization information to the access network device.

[0158] For example, if the second indication information of the access network device does not match the contract information, authorization will not be granted.

[0159] Optionally, the authorization information may change. For example, when an IoT intermediate node switches across base stations, the core network may re-provide authorization information, such as changing the authorization information from authorized to unauthorized, or, in other embodiments, from unauthorized to authorized.

[0160] Optionally, the method further includes:

[0161] Second configuration information is sent to the IoT intermediate node, where the second configuration information includes at least one of the following: a transmitting and receiving frequency, a bandwidth, a power, and a coverage area.

[0170] Send third indication information to the IoT intermediate node, where the third indication information is used to instruct the IoT intermediate node to at least one of the following: stop the service of the IoT intermediate node, start the service of the IoT intermediate node, or resume the service of the IoT intermediate node.

The method includes:

[0172] Step 401: Receive second indication information from an access network device; the second indication information is used to indicate that the target node is an IoT intermediate node;

[0173] Step 402: Determine whether to authorize the target node as an IoT intermediate node based on the second indication information;

[0174] Step 403: Send authorization information to the access network device, where the authorization information is used to indicate whether the target node is authorized as an IoT intermediate node.

[0178] Sending authorization change indication information to the access network device.

[0179] Optionally, according to an Internet of Things communication method according to an embodiment of the present application, the method further includes:

[0180] Send third indication information to the IoT intermediate node, where the third indication information is used to instruct the target node to at least one of the following: stop the service of the IoT intermediate node, start the service of the IoT intermediate node, or resume the service of the IoT intermediate node.

[0181] For example, Figure 5 As shown, the method includes the following steps:

[0182] Step 501: The cell selection process of the IoT intermediate node may be implemented based on at least one of the following: a) indication information in the cell SI, b) pre-configuration information (such as a list of cells allowed to be accessed), c) first accessing the network as a normal terminal, establishing a user plane, and downloading configuration information (such as a list of cells allowed to be accessed) from the corresponding server;

[0183] Step 502: Access of intermediate nodes;

[0184] The intermediate node sends device type indication information to the access network device, which is used to indicate that the intermediate node is an IoT intermediate node.

[0185] Step 503: The access network device sends a registration message, such as an Initial UE Message, to the core network device.

[0186] The registration message carries the Internet of Things intermediate node indication information, that is, indicates that the intermediate node is an Internet of Things intermediate node.

[0187] Step 504: The core network device sends a UE context establishment request message to the access network device, which carries the IoT intermediate node authorization information.

[0188] Step 505: Configuration process of the IoT intermediate node;

[0189] For example, the access network device sends the second configuration information to the IoT intermediate node.

[0190] Step 506: The access network device sends a UE context establishment completion message to the core network device.

[0191] Step 507: The core network device sends a UE context modification request message to the access network device, for example, carrying new authorization information.

[0192] The new authorization information is, for example, a change from authorization to non-authorization for an IoT intermediate node, or from non-authorization to authorization.

[0193] Step 508: The access network device sends a UE context modification completion message to the core network device.

[0194] For example, if the new authorization information is changed from authorization to non-authorization for the IoT intermediate node, the access network device sends a third indication information to the IoT intermediate node to stop the service, or if the new authorization information is changed from non-authorization to authorization, the access network device sends a third indication information to the IoT intermediate node to start the service.
