Technical Field

The present application relates to the field of communications, and in particular to a communication method and device.

Background technique

The existing 3rd Generation Partnership Project (3GPP) is studying standards related to personal IoT networks (PINs). The standards discuss the communication of IoT devices (such as personal IoT entities (PIN elements, PINEs)) in a variety of ways, including: IoT devices directly communicate with IoT management entities to achieve PIN management; and also include IoT devices and IoT management entities communicating via IoT gateway entities to achieve PIN management. In the scenario where the IoT device, IoT management entity and IoT gateway entity are all within the direct communication range, the IoT device can send IoT messages directly to the IoT management entity, or send IoT messages to the IoT management entity through the IoT gateway entity. At this time, the IoT device may send IoT messages to the IoT management entity and the IoT gateway entity at the same time, resulting in a waste of communication resources.

In an embodiment of the present application, the IoT device first determines the object to which the IoT device sends the IoT message, and then sends the IoT message to the determined object. In a scenario where the IoT device, the IoT management entity, and the IoT gateway entity are all within a direct communication range, the object to which the IoT message is sent can be determined, and the IoT message can be sent to the determined object, thereby avoiding unnecessary signaling consumption and saving communication resources.

In an embodiment of the present application, the target wireless access type corresponding to the object is directly determined by the Internet of Things device, and then an Internet of Things message is sent to the determined object based on the target wireless access type. In a scenario where the Internet of Things device, the Internet of Things management entity and the Internet of Things gateway entity are all within a direct communication range, the Internet of Things message is sent to the determined object based on the target wireless access type, which can avoid the Internet of Things switching the object of the current wireless access network communication connection, avoid unnecessary signaling consumption, and save communication resources.

In one possible design, the first indication information may also indicate a target wireless access type corresponding to the object; then the Internet of Things device sends an Internet of Things message to the object, which may include: sending an Internet of Things message to the object using the target wireless access type corresponding to the object.

In an embodiment of the present application, when the object is an Internet of Things gateway entity and the Internet of Things device is currently connected to the Internet of Things management entity through a first target wireless access type, the Internet of Things device first disconnects the connection of the first target wireless access type with the Internet of Things management entity, and then establishes a connection of the first target wireless access type between the Internet of Things device and the Internet of Things gateway entity, which can ensure successful sending of the Internet of Things message.

In addition, the network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

Before introducing the embodiments of the present application, some terms involved in the embodiments of the present application are explained.

5th generation mobile communication technology (5G) network architecture: As shown in Figure 1, the 5G system architecture is divided into two parts: access network and core network. The access network is used to implement functions related to wireless access. The core network may include the following network elements: user plane function (UPF), authentication server function (AUSF), access and mobility management function (AMF), session management function (SMF), network exposure function (NEF), network function repository function (NRF), policy control function (PCF) and unified data management (UDM), and optionally, application function (AF) and unified data repository (UDR).

AMF is mainly responsible for mobility management in mobile networks, such as user location update, user registration network, user switching, etc. SMF is mainly responsible for session management in mobile networks, such as session establishment, modification, and release. UPF is responsible for forwarding and receiving user data in terminal devices. It can receive user data from the data network and transmit it to the terminal device through the access network device; it can also receive user data from the terminal device through the access network device and forward it to the data network. PCF mainly supports the provision of a unified policy framework to control network behavior, provides policy rules to the control layer network function, and is responsible for obtaining user subscription information related to policy decisions. AUSF is used to perform UE security authentication. NEF is mainly used to support the opening of capabilities and events. NRF is used to provide storage and selection functions of network function entity information for other network elements. UDM is used to store user data, such as subscription data, authentication/authorization data, etc. AF interacts with the 3GPP core network to provide application layer services, such as providing information about application layer data routing, providing access network capability opening functions, interacting with the policy framework to provide policy control, and interacting with the IP multimedia subsystem (IMS) of the 5G network.

The data network (DN) is used to provide business services to users. It can be a private network, such as a local area network; it can also be an external network that is not controlled by the operator, such as the Internet; it can also be a proprietary network jointly deployed by operators, such as the IMS network. Terminal devices can access the DN through established protocol data unit (PDU) sessions.

PIN is being studied in the 3GPP standards organization. In the PIN service, users can create their own Internet of Things (IoT) network. The following device types are included in the PIN architecture:

Personal Internet of Everything Network Entity (PIN element, PINE): An IoT device in a PIN, which can be a 3GPP UE or a non-3GPP device, can discover a PIN or other PINEs in a PIN, and join or leave a PIN.

PIN gateway capability (PEGC): It is a role or capability of PINE, which can also be understood as a PINE with gateway function, used to realize information exchange between other PINEs in PIN and 5GC, and provide data routing and forwarding for PINE. The terminal that realizes PEGC function can be called IoT gateway terminal.

PIN management capability (PEMC): It is a role or capability of PINE, which can also be understood as PINE with management function, used to manage PIN, such as creating, updating, deleting PIN, adding and removing PINE, and PEGC configuration management. The terminal that implements PEMC function can be called IoT management terminal.

PINE, PGEC, and PEMC can be software modules running on UE devices or IoT devices. A device may have one or more of the above capabilities. For example, a UE may have the capabilities of PINE, PEGC, and PEMC. It can also be understood that a UE may serve as an IoT device, an IoT management entity, and an IoT gateway entity at the same time.

The PINE, PEGC and PEMC in the embodiments of the present application may also refer to PINE client, PEGC client and PEMC client. Among them, PEMC client can be understood as PINE with PEMC capability, and PEGC client can be understood as PINE with PEGC capability.

Here are some architectural options under discussion:

As shown in Figure 2, it is a PIN architecture enhanced by the control plane. This architecture introduces a personal Internet of Things control function (PIN control function, PINCTRL) network element in the 5G core network to authorize PEMC/PEGC and maintain PIN information (including a PIN member list, where PIN member attributes include <device identification, device capability, name, IP or MAC address, whether it is PEGC, whether it can access the 5G system, device type, etc.>).

As shown in Figure 3, it is another control plane enhanced PIN architecture, which introduces PIN-F: capable of managing PIN, such as PIN creation, PEMC role allocation, PIN ID allocation, etc. PEF refers to the PINE function; PEMCF refers to the function of managing PIN capability (i.e. PEMC); PEGCF refers to the PEGC function. P1 represents the wireless access type between two PINEs. P1 can use non-3GPP access technology (such as WiFi, Bluetooth BT, zigbee). P2 represents the wireless access type between PEGC and PEMC. P2 can use the proximity services (prose) technology in 5G. There is no direct interface/reference point between PINE and PEMC in this architecture.

As shown in Figure 4, it is a PINMF-based architecture. The PIN management function (PINMF) in this architecture is a specific AF in the 5G system, which provides the following functions: receiving a request message from PEMC to establish a PIN, providing PIN information and PIN member information, updating PIN (including updating PIN members), configuring PIN discovery information, and PEGC access control information. In this architecture, PINE has reference points/interfaces with both PEMC and PEGC. Specifically, Pin2 is based on a direct connection, while Pin1 can be based on a direct connection, or PEGC, or 5GC.

As shown in Figure 5, it is a PIN architecture based on the existing 5G network element (5G System, 5GS), which includes an application server (AS). Compared with the previous ones, this architecture does not introduce new network elements in the core network to control and manage PIN. In this architecture, PINE and PEGC communicate through P1 (based on non-3GPP access technology such as wireless network communication technology (Wireless Fidelity, WiFi), Bluetooth (BlueTooth, BT), ZigBee, etc.), and PEMC and PEGC communicate through P2 (based on non-3GPP access technology or 5G prose technology).

As shown in Figure 6, it is a PIN architecture based on the existing 5GS, without application function (AF). Compared with the previous ones, this architecture does not introduce new network elements in the core network to manage PIN. The absence of AF here means that AF is not responsible for the management of PIN, but PINE can access the application server AS, and AF can perform functions that affect user plane routing. In this architecture, PINE communicates with PEMC through P1 (P1 is based on non-3GPP access technology), and communicates with PEGC through P2 (P2 uses direct communication (non-3GPP access technology) or the Internet), and PEMC and PEGC communicate through P3 (based on non-3GPP access technology or 5G prose technology).

For existing non-3GPP Internet of Things (IoT) devices, PINE can only connect to one terminal using one RAT. For example, a Bluetooth headset can only connect to one UE, but not to two UEs at the same time.

As shown in Figure 7, if both PEGC and PEMC are within direct communication range, PINE can use two different radio access technologies (RAT) to connect to PEGC and PEMC respectively. As shown in Figure 8, at the same time, only one device can be connected. If you want to communicate with another device later, you can disconnect the current connection and connect to the other device.

As shown in FIG9 , the Non-3GPP device is within the direct communication range with the PEGC, but may not be within the direct communication range with the PEMC.

In the existing 3GPP standard TR solution, the IoT management terminal has multiple communication methods for PIN management. PINE and PEMC directly communicate (Direction communication) to achieve PIN management, such as joining; or PINE achieves PIN management via PEGC and PEMC, such as joining.

In the scenario where PINE, PEMC and PEGC are all within the direct communication range, PINE can either send PIN management messages (for example, PIN join, PIN discovery, PIN invite ack, etc.) to PEMC through direct communication with PEMC, and the routing path of the message is from PINE to PEMC; or send the same PIN management message to PEGC through direct communication with PEGC, and PEGC further forwards the management message to PEMC, and the routing path of the message is from PINE to PEGC, and then from PEGC to PEMC or AS. In the prior art, PINE can send the same PIN management message in the above two ways, that is, PINE will send two identical PIN management messages, and PEMC will receive two identical management messages sent by PINE. This will cause a waste of communication resources, PINE resources, and PEMC resources.

In order to solve the above technical problems, an embodiment of the present application provides a communication method. The method provided by the embodiment of the present application is described below in conjunction with the drawings in the specification.

The communication method provided in the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, fifth generation (5G) mobile communication system, wireless fidelity (WiFi) system, future communication system, or a system integrating multiple communication systems, etc., which is not limited in the embodiments of the present application. Among them, 5G can also be called new radio (NR).

The communication method provided in the embodiments of the present application can be applied to various communication scenarios, for example, it can be applied to one or more of the following communication scenarios: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), machine type communication (MTC), massive machine type communication (mMTC), device to device (D2D), vehicle to everything (V2X), vehicle to vehicle (V2V), and internet of things (IoT), etc.

The communication method provided in the embodiment of the present application is described below using the communication system shown in FIG. 10 as an example.

FIG10 is a schematic diagram of a communication system provided by an embodiment of the present application. As shown in FIG10 , the present application is described by taking PIN as an example of the Internet of Things. The communication system may include:

IoT devices (e.g. PINE), IoT management entities (e.g. PEMC), and IoT gateway entities (e.g. PEGC).

Taking the IoT device as PINE as an example, PEMC creates a PIN and generates corresponding PIN information (PIN profile). The networking information at least includes the PIN identification, PEMC (which includes the following information of PEMC: identification, address, communication capability information, etc.) and PEGC information (which includes the following information of PEGC: identification, address, communication capability information, etc.). The PIN information is sent to PINE, for example, in a PIN announcement message or a PIN invite message. PINE can establish a PIN service connection with PEGC based on the PIN information, which can be an application layer connection or a transport layer connection.

The following describes the communication method provided in the embodiment of the present application by taking the Internet of Things management entity as the Internet of Things management terminal and the Internet of Things gateway entity as the Internet of Things gateway terminal as an example.

It should be noted that FIG10 is only an exemplary framework diagram, and the number of nodes included in FIG10 and the states of the nodes are not limited. In addition to the functional nodes shown in FIG10, other nodes may also be included, such as: core network equipment, gateway equipment, application servers, etc., without limitation. The above nodes may communicate with the core network equipment in a wired or wireless manner, such as through a next generation (NG) interface.

FIG11 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG11 , the method may include the following steps:

S110, the IoT device determines the object to which the IoT device sends the IoT message.

Among them, the object is selected according to the wireless access type supported by the IoT device, the IoT management terminal and the IoT gateway terminal. The object can be an IoT management terminal or an IoT gateway terminal. It can be understood that the object to which the IoT device sends an IoT message refers to the next hop node on the routing path for receiving the IoT message. Furthermore, the object can be directly selected by the IoT device, that is, the IoT device determines the object to which the IoT device sends the message, or the IoT management terminal selects and indicates it to the IoT device through the first indication information (which can directly indicate the object, or can indicate the object and the priority of the object).

Furthermore, the IoT device can determine the object to which the IoT device sends the IoT message by the following method: the IoT management terminal selects the object according to the wireless access type supported by the IoT device, the IoT management terminal and the IoT gateway terminal, and then sends it to the IoT device through the first indication information, the IoT device determines the sending object from the first indication information, and then the IoT device executes S111. The steps shown in FIG. 12 are described in detail below.

In another optional manner, the IoT device may select an object according to the wireless access type supported by the IoT device, the IoT management terminal, and the IoT gateway terminal, that is, the IoT device determines the object to which the IoT device sends a message and executes S111. The steps shown in FIG. 14 are described in detail below.

The objects to which multiple IoT messages are sent can be the same or different. For example, the objects to which multiple PIN join messages are sent are the same, while the objects to which PIN join messages and PIN discovery messages are sent are different.

S111, the IoT device sends an IoT message to the object.

Among them, the IoT message can be a type of message used to manage IoT devices. For example, the IoT message can be a PIN join Request message, PIN discovery request message, PIN invite ack message, etc.

When the determined object is an IoT gateway terminal, the IoT device sends an IoT message to the IoT gateway terminal through a direct communication connection with the IoT gateway. After receiving this specific type of message, the IoT gateway terminal will forward it to the IoT management terminal.

When the determined object is an IoT management terminal, the IoT device sends an IoT message to the IoT management terminal through a direct communication connection with the IoT management terminal.

As described above, in the case where the IoT device determines the object by itself, or the IoT device determines the sending object from the first indication information, and the first indication information directly indicates the object, the IoT device only sends the IoT message to the determined object. In the case where the IoT device determines the sending object from the first indication information, and the first indication information indicates multiple objects and the priority of each object, the IoT device first sends the IoT message to the object with the high priority. For the specific description of sending the IoT message, refer to the case of directly indicating the object above. If the sending fails, the IoT message is sent to the object with the next priority.

In an embodiment of the present application, the IoT device first determines the object to which the IoT device sends the IoT message, and then sends the IoT message to the determined object. In a scenario where the IoT device, the IoT management terminal, and the IoT gateway terminal are all within a direct communication range, the object to which the IoT message is sent can be determined, and the IoT message can be sent to the determined object, thereby avoiding sending the same IoT message to multiple communicative nodes, reducing signaling consumption, and saving communication resources.

The following first introduces an embodiment in which the Internet of Things management terminal selects an object (or an object and an object priority) to which the Internet of Things device sends an Internet of Things message and indicates it to the Internet of Things device through first indication information. Accordingly, as shown in FIG12, in one embodiment, the method may include:

S120, the Internet of Things management terminal receives a second wireless access type supported by the Internet of Things gateway terminal and a third wireless access type supported by the Internet of Things device.

Among them, the wireless access type supported by the IoT gateway terminal is called the second wireless access type, which can be sent by the IoT gateway terminal to the IoT management terminal, for example, when the IoT gateway terminal establishes direct communication (such as WiFi connection) with the IoT management terminal, the second wireless access type is sent to the IoT management terminal; the wireless access type supported by the IoT device is called the third wireless access type, which can be sent by the IoT device to the IoT management terminal, for example, when the IoT device establishes direct communication (such as WiFi connection) with the IoT management terminal, the second wireless access type is sent to the IoT management terminal. It can be understood that there can be one or more wireless access types (i.e., the second wireless access type) supported by the IoT gateway terminal, and there can also be one or more wireless access types (i.e., the third wireless access type) supported by the IoT device.

Further, the Internet of Things management terminal can obtain the second wireless access type in the process of establishing a 3GPP short-range communication connection (such as PC5 connection)/non-3GPP connection (such as WIFI, BT, etc.) with the Internet of Things gateway terminal, or receive the second wireless access type from the Internet of Things gateway terminal after the connection is established (the Internet of Things gateway terminal actively reports the second wireless access type to the Internet of Things management terminal after the connection is established, or the Internet of Things management terminal requests the second wireless access type from the Internet of Things gateway terminal, and the Internet of Things gateway terminal sends the second wireless access type to the Internet of Things management terminal in the response message of the request). Similarly, the Internet of Things management terminal can obtain the third wireless access type in the process of establishing a PC5 connection/non-3GPP connection (WIFI, BT, etc.) with the Internet of Things device, or receive the third wireless access type from the Internet of Things device after the connection is established (the Internet of Things device actively reports the third wireless access type to the Internet of Things management terminal after the connection is established, or the Internet of Things management terminal requests the third wireless access type from the Internet of Things device, and the Internet of Things device sends the third wireless access type to the Internet of Things management terminal in the response message of the request).

S121, the Internet of Things management terminal determines first indication information according to the first wireless access type, the second wireless access type and the third wireless access type.

Among them, the wireless access type supported by the Internet of Things management terminal is called the first wireless access type. It can be understood that the wireless access type supported by the Internet of Things management terminal can be one or more. The Internet of Things management terminal can determine the first wireless access type from the information configured by itself. The first indication information can indicate the object (or the object and the priority of the object) to which the Internet of Things device sends the Internet of Things message, and further indicates the target wireless access type applied by the object to send the Internet of Things message. The following will introduce how to determine the first indication information in conjunction with the example of Table 1.

Then, S110, the IoT device determines the object to which the IoT device sends the IoT message, which may include:

S122, the Internet of Things management terminal sends first indication information to the Internet of Things device, and correspondingly, the Internet of Things device receives the first indication information from the Internet of Things management terminal.

After receiving the first indication information, the IoT device sends an IoT message to the object indicated by the first indication information. If the object is an IoT management terminal, the IoT management terminal receives the IoT message from the IoT device; if the object is an IoT gateway terminal, the IoT gateway terminal receives the IoT message from the IoT device and sends the IoT message to the IoT management terminal. The corresponding IoT management terminal receives the IoT message forwarded by the IoT gateway terminal.

Furthermore, determining the first indication information according to the first wireless access type, the second wireless access type and the third wireless access type can be divided into multiple situations. Exemplarily, Table 1 shows situations in which the first indication information is determined in several communication scenarios, as shown in Table 1.

Table 1

Priority 1 in Table 1 has higher priority than priority 2.

Referring to situation 1 or situation 2 in Table 1, when the IoT device only supports one non-3GPP technology, and the IoT management terminal and the IoT gateway terminal support one or more non-3GPP technologies, the first indication information determined by the IoT management terminal may be sent to the IoT gateway terminal; or sent to the IoT management terminal; or the priority of sending to the IoT gateway terminal is higher than the priority of sending to the IoT management terminal. The target wireless access type used by the IoT gateway terminal and the IoT management terminal can only be one wireless access type supported by the IoT device. Specifically, the IoT management terminal may determine the first indication information in any of the following situations:

(1) The IoT management terminal determines that the first indication information indicates that an IoT message is to be sent to the IoT gateway terminal. For example, if the IoT management terminal (for example, the IoT management terminal is a mobile phone) moves out of the range of direct communication with the IoT device, resulting in disconnection of the direct communication connection, the IoT management terminal may determine that the object to which the IoT message is to be sent is the IoT gateway terminal, or the IoT management terminal considers that the communication between the IoT management terminal and the IoT gateway terminal is based on Uu communication, then the IoT management terminal may determine that the first indication information is to send an IoT message to the IoT gateway terminal, or the IoT management terminal prefers to receive the IoT message through the IoT gateway terminal.

(2) The IoT management terminal determines that the first indication information can be sent to the IoT management terminal. The IoT management terminal and the IoT device basically do not move (for example, the IoT management terminal is a smart screen in the home). The IoT management terminal determines that it can be located within a direct communication range with the IoT device and maintain a direct communication connection. Then, the IoT management terminal can determine that the object of the IoT message is the IoT management terminal.

(3) The IoT management terminal determines that the first indication information may indicate that the objects to be sent are the IoT gateway terminal and the IoT management terminal, and further indicates the priority of the IoT gateway terminal and the IoT management terminal, which can be understood as indicating that the IoT gateway terminal or the IoT management terminal is given priority. The detailed implementation of the IoT management terminal determining that the IoT gateway terminal is given priority can refer to (1), and the detailed implementation of the IoT management terminal determining that the IoT management terminal is given priority can refer to (2).

Referring to Cases 3 to 5 in Table 1, when the IoT device supports multiple non-3GPP technologies, and the IoT management terminal and the IoT gateway terminal support one or more non-3GPP technologies, the first indication information determined by the IoT management terminal may be sent to the IoT gateway terminal; or sent to the IoT management terminal; or sent to the IoT gateway terminal and the IoT management terminal; or the priority sent to the IoT gateway terminal precedes the priority sent to the IoT management terminal; or the priority sent to the IoT management terminal precedes the priority sent to the IoT gateway terminal. The target wireless access type applied by the IoT gateway terminal and the IoT management terminal may be a wireless access type supported by the IoT device and also supported by the IoT gateway terminal or the IoT management terminal.

Exemplarily, the IoT device currently has a direct communication connection with the IoT management terminal. If the determined object is the IoT management terminal, and the IoT device only supports one non-3GPP RAT, the IoT device continues to maintain the connection with the IoT management terminal, and sends a PIN join/discover request message to the IoT management terminal, and after the join/discover process is completed, disconnects from the IoT management terminal (for example, turns off the AP mode and switches to the STA mode), connects to the IoT gateway terminal, and performs subsequent communications with other IoT devices or IoT management terminals. Specifically, if the IoT message is a PIN join request message, if the IoT management terminal allows the IoT device to join the PIN specified by the PIN Join message, the information of the IoT device is added to the created PIN configuration file, and then a PIN join/update/synchronize message is sent to the PIN server. The PIN server synchronously updates the PIN configuration file and returns a response message to the IoT management terminal. The IoT management terminal returns a response message of the PIN join request to the IoT device, indicating that the IoT device has joined successfully. If the IoT message is a PIN discover request message, the IoT management terminal searches for PIN information that meets the requirements of the PIN discover request message from the IoT management terminal, or optionally, the IoT management terminal can also send a PIN discover request message to the PIN server, and obtain PIN information that meets the requirements of the PIN discovery request message from the PIN server. The IoT management terminal returns the discovered PIN information to the IoT device. The PIN information can be the local PIN information of the IoT management terminal, or the PIN information obtained from the PIN server, or both).

In another example, the IoT device currently has a direct communication connection with the IoT management terminal. If the determined object is an IoT gateway terminal, and the IoT device only supports one non-3GPP RAT, the IoT device first disconnects from the IoT management terminal (for example, turns off the AP mode and switches to the STA mode), connects to the IoT gateway terminal, and then sends a PIN join/discover request message to the IoT gateway terminal. The IoT gateway terminal sends the join/discover request message to the IoT management terminal or the PIN server for processing. The IoT gateway terminal later sends a response message to the IoT device for the PIN join/discover request message received from the IoT management terminal or the PIN server. When the IoT message is a PIN join request message, the response message indicates whether the join is successful or failed. When the IoT message is a discover request message, the response message contains the discovered PIN information (if successful).

In the embodiment of the present application, the Internet of Things management terminal instructs the object to send the Internet of Things message to the Internet of Things device through the first indication information. (or object priority), in the scenario where the IoT device, the IoT management terminal and the IoT gateway terminal are all within the direct communication range, the object to which the IoT message is to be sent can be determined, and the IoT message can be sent to the determined object, avoiding unnecessary signaling consumption and saving communication resources.

In one embodiment, considering that there are scenarios where the IoT device supports multiple wireless access types, and the IoT gateway terminal or IoT management terminal also supports multiple wireless access types (such as scenarios 3-5 in Table 1), some communication scenarios require the connection state of the IoT device to be stable, and try to avoid the IoT switching the object of the current wireless access network communication connection. For example, if the IoT device supports stateful services such as video, VR, etc., the IoT device needs to maintain a stable connection with the IoT management terminal, then the IoT device can choose to send IoT messages through the IoT gateway terminal to ensure that the communication connection between the IoT device and the IoT management terminal is stable, thereby ensuring the continuous execution of stateful services.

For this reason, the present application also provides an embodiment of determining the first indication information by referring to the wireless access type of the IoT device currently connected to the IoT gateway terminal (or IoT management terminal, depending on whether the IoT device is currently directly connected to the IoT gateway terminal or the IoT management terminal). Accordingly, as shown in FIG13 , for the scenario where the IoT device is currently directly connected to the IoT gateway terminal, the method may further include:

S130, the Internet of Things management terminal receives the wireless access type of the Internet of Things device currently connected to the Internet of Things gateway terminal.

The IoT management terminal can receive the wireless access type of the IoT device currently connected to the IoT gateway terminal from the IoT device side, or can receive the wireless access type of the IoT device currently connected to the IoT gateway terminal from the IoT gateway terminal side. FIG13 takes receiving from the IoT device side as an example.

S131, the Internet of Things management terminal determines the target wireless access type corresponding to the Internet of Things gateway terminal and/or the target wireless access type corresponding to the Internet of Things management terminal according to the wireless access type, the first wireless access type, the second wireless access type, and the third wireless access type currently connected between the Internet of Things device and the Internet of Things gateway terminal.

Among them, the corresponding scenario of step S131 is the current direct communication connection between the IoT device and the IoT gateway terminal.

If the third wireless access type is multiple (for example, WiFi and BT), and the first wireless access type and the second wireless access type are also WiFi and BT, then the target wireless access type corresponding to the Internet of Things gateway terminal is determined to be the wireless access type (assuming it is WiFi) to which the Internet of Things device and the Internet of Things gateway terminal are currently connected, and the target wireless access type corresponding to the Internet of Things management terminal is determined to be BT.

If the third wireless access type is unique (eg, WiFi), the target wireless access type corresponding to the Internet of Things gateway terminal and/or the target wireless access type corresponding to the Internet of Things management terminal are both WiFi.

If the third wireless access type is multiple (for example, WiFi and BT) and the first wireless access type is one (for example, WiFi), the target wireless access type corresponding to the Internet of Things management terminal is WiFi; if the second wireless access type is multiple (for example, WiFi and BT), the target wireless access type corresponding to the Internet of Things gateway terminal is determined to be the wireless access type (assuming it is WiFi) to which the Internet of Things device and the Internet of Things gateway terminal are currently connected.

If the third wireless access type is multiple (for example, WiFi and BT), the first wireless access type is multiple (for example, WiFi and BT), and the second wireless access type is one (for example, WiFi), then the target wireless access type corresponding to the Internet of Things gateway terminal is determined to be the wireless access type (must be WiFi) to which the Internet of Things device and the Internet of Things gateway terminal are currently connected, and the target wireless access type corresponding to the Internet of Things management terminal is preferably determined to be BT, and can also be determined to be WiFi, but determining it as WiFi requires the Internet of Things device to disconnect the WiFi connection with the Internet of Things gateway terminal.

Furthermore, the target wireless access type corresponding to the Internet of Things gateway terminal can be indicated to the Internet of Things device through the first indication information.

Similarly, for a scenario where the IoT device currently has a direct communication connection with the IoT management terminal, the method may further include:

The Internet of Things management terminal determines the target wireless access type corresponding to the Internet of Things management terminal and/or the target wireless access type corresponding to the Internet of Things gateway terminal based on the wireless access type, the first wireless access type, the second wireless access type, and the third wireless access type to which the Internet of Things device is currently connected to the Internet of Things management terminal.

Among them, the determination logic of the target wireless access type corresponding to the Internet of Things management terminal and/or the target wireless access type corresponding to the Internet of Things gateway terminal in this scenario is the same as the determination logic principle described in S131, and will not be repeated here.

S132, the Internet of Things management terminal sends first indication information to the Internet of Things device.

Among them, the first indication information indicates the target wireless access type corresponding to the Internet of Things management terminal.

Then S111, the IoT device sends an IoT message to the object, which may include:

S133, the IoT device sends an IoT message to the object using the target wireless access type corresponding to the object.

In the embodiment of the present application, the target wireless access type corresponding to the object to which the IoT device sends the IoT message is first determined, and then Sending an Internet of Things message to the determined object based on the target wireless access type can avoid the Internet of Things switching the object of the current wireless access network communication connection, avoid unnecessary signaling consumption, and save communication resources.

The above introduces an embodiment in which the Internet of Things management terminal selects the object to which the Internet of Things device sends the Internet of Things message (it can also be the priority of the object) and determines the target wireless access type corresponding to the object, and indicates it to the Internet of Things device through the first indication information, and the Internet of Things device can also directly select the object to which the Internet of Things device sends the Internet of Things message and determine the target wireless access type corresponding to the object. The following introduces the Internet of Things device directly selecting the object to which the Internet of Things device sends the Internet of Things message and the target wireless access type corresponding to the object. The specific implementation principle can refer to the introduction of the Internet of Things management terminal determining the first message mode to select the object to which the Internet of Things device sends the Internet of Things message (it can also be the priority of the object) and determine the target wireless access type corresponding to the object, and will not be repeated here. As shown in Figure 14, in one embodiment, S110: The Internet of Things device determines the object to which the Internet of Things device sends the Internet of Things message, which may include:

S140, the Internet of Things device receives a first wireless access type supported by the Internet of Things management terminal and a second wireless access type supported by the Internet of Things gateway terminal.

Among them, the first wireless access type and the third wireless access type have at least one identical wireless access type, the second wireless access type and the third wireless access type have at least one identical wireless access type, and the third wireless access type is a wireless access type supported by the Internet of Things device.

S141, the Internet of Things device selects an object to send an Internet of Things message according to the first wireless access type, the second wireless access type and the third wireless access type.

The principle of selecting an object can be referred to the description of S121-S122 and will not be elaborated here.

In an embodiment of the present application, the object to which the IoT device sends the IoT message is directly selected through the IoT device, and then the IoT message is sent to the determined object. In a scenario where the IoT device, the IoT management terminal and the IoT gateway terminal are all within the direct communication range, the object to which the IoT message is sent can be determined, and the IoT message can be sent to the determined object, thereby avoiding unnecessary signaling consumption and saving communication resources.

On the other hand, as shown in FIG. 15 , an embodiment is also provided for an implementation method in which an IoT device determines a target wireless access type corresponding to an object, and the method further includes:

S150, the IoT device determines a target wireless access type for sending an IoT message to an object according to the wireless access type, the first wireless access type, the second wireless access type, and the third wireless access type to which the IoT device is currently connected to the IoT management terminal.

The communication scenario is that the IoT device currently has a direct communication connection with the IoT management terminal. The specific implementation principle can be referred to the description of S131 and will not be repeated here.

In another possible implementation, S150 may further include:

The Internet of Things device determines the target wireless access type used for sending an Internet of Things message to an object according to the wireless access type, the first wireless access type, the second wireless access type, and the third wireless access type to which the Internet of Things device is currently connected to the Internet of Things gateway terminal; accordingly, the Internet of Things device sends an Internet of Things message to the object, including: the Internet of Things device sends the Internet of Things message to the object through the target wireless access type corresponding to the object.

The communication scenario is that the IoT device currently has a direct communication connection with the IoT gateway terminal. The specific implementation principle can be referred to the description of S131 and will not be repeated here.

Then S111 may include:

S151, the IoT device sends an IoT message to the object using the target wireless access type corresponding to the object.

Among them, in the scenario where the target wireless access type corresponding to the object is occupied by the connection between the IoT device and other nodes on the IoT device, the connection of the target wireless access type between other network elements and the IoT device can be disconnected first, and then a connection of the target wireless access type can be established between the object and the IoT device.

Exemplarily, the target wireless access type corresponding to the Internet of Things gateway terminal is the first target wireless access type; when the object is the Internet of Things gateway terminal, and the Internet of Things device is currently connected to the Internet of Things management terminal through the first target wireless access type, the method may also include:

The Internet of Things device disconnects the connection of the first target wireless access type with the Internet of Things management terminal; and the Internet of Things device establishes a connection of the first target wireless access type with the Internet of Things gateway terminal.

For IoT devices that support the use of the same wireless access type to simultaneously connect to the IoT management terminal and the IoT gateway terminal, if the current IoT device is connected to the IoT management terminal via WiFi, the determined object is the IoT gateway terminal and the determined object When the networked device uses WiFi connection with the Internet of Things gateway terminal, the Internet of Things device can disconnect the WiFi connection with the Internet of Things management terminal. It can disconnect the WiFi connection with the Internet of Things management terminal before, during, or after establishing a WiFi connection with the Internet of Things gateway. The present invention does not limit this.

In an embodiment of the present application, the target wireless access type corresponding to the object is directly determined by the IoT device, and then an IoT message is sent to the determined object based on the target wireless access type. In a scenario where the IoT device, the IoT management terminal, and the IoT gateway terminal are all within a direct communication range, the object to which the IoT message is to be sent can be determined, and the IoT message can be sent to the determined object, thereby avoiding unnecessary signaling consumption and saving communication resources.
