Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to an intelligent control method and system based on the Internet of Things. Background Art

[0002] With the rapid development of science and technology, the Internet of Things (IoT) has become an indispensable part of our lives. The concept of IoT was first proposed by Kevin Ashton in 1999, who defined IoT as "a network in which ordinary objects can collect and exchange data through embedded electronic devices, software, sensors, actuators and network connections". Today, IoT has been widely used in various fields, including smart homes, healthcare, transportation, agriculture, industry, etc.

[0003] The core of the IoT system is the interconnection of terminal devices. These devices are connected through various means (such as Wi-Fi, Bluetooth, ZigBee, LoRa, etc.) to form a huge network. Between these devices, data exchange and control signaling interaction can be carried out through side-channel connection. For example, PC5 connection is a side-channel connection method that allows devices to interact through PC5 connection.

[0004] However, as the scale of IoT networking grows, the amount of interactive data and signaling also increases. This places higher demands on the data processing and signaling processing capabilities of IoT systems. Traditional IoT systems often find it difficult to meet these requirements. Therefore, the optimization and improvement of IoT systems has become an important direction for the development of science and technology. Summary of the invention

[0047] The terminal may be a terminal with transceiver functions, or a chip or chip system that may be provided in the terminal.

[0048] The IoT system can be applied to the ambient IoT (A-IoT) scenario, which is also called the ambient power-enabled IoT or the passive IoT (P-IoT). A-IoT can be applied to a variety of value scenarios. In the A-IoT scenario, the terminal can also be called an A-IoT device.

[0049] Figure 2 The flowchart of the method provided by the embodiment of the present invention is as follows. The intelligent control method based on the Internet of Things is applicable to the above-mentioned Internet of Things system and involves the interaction between devices in the above-mentioned Internet of Things system. The specific process is as follows:

[0050] S201: When a second terminal joins an Internet of Things system by establishing a connection with a first terminal, the first terminal determines a network influence factor of the second terminal.

[0051] The first terminal may be a terminal with a relay function in the Internet of Things system. The first terminal is connected to N terminals among the M terminals, where N is an integer greater than or equal to 1 and less than M. The second terminal may establish a connection with the first terminal, such as a PC5 connection, and may be implemented by using an existing connection establishment method to join the Internet of Things system.

[0052] The network influence factor of the second terminal may be used to determine the influence of the communication between the second terminal and the first terminal on the communication between the first terminal and N terminals.

[0053] For example, when the second terminal establishes a connection with the first terminal, the first terminal may obtain service plane information and / or control plane information from the second terminal, the service plane information indicating the service that the first terminal interacts with the second terminal, and the control plane information indicating the control signaling that the first terminal interacts with the second terminal. For example, the service plane information may indicate K types of services that the first terminal and the second terminal may interact with, K is an integer greater than or equal to 1, and the K types of services may be different types of services, such as video services, audio services, image services, data synchronization services, etc., which are not specifically limited. The control plane information may indicate L types of control signaling that the first terminal and the second terminal may interact with, L is an integer greater than or equal to 1, and the L types of control signaling may be different types of control signaling, high-layer control signaling (such as application layer control signaling), middle-layer control signaling (such as PDCP layer control signaling) or physical layer control signaling (such as PHY layer control signaling, etc.), which are not specifically limited. The first terminal determines the network impact factor of the second terminal based on the service plane information and / or control plane information. The first terminal weights and averages the impact weights corresponding to the K types of services to obtain the first weight mean, and weights and averages the impact weights corresponding to the L types of control signaling to obtain the second weight mean. It can be understood that different types of services can correspond to different impact weights (the corresponding relationship can be pre-configured), such as the impact weight corresponding to the audio service is 0.1, the impact weight corresponding to the image service is 0.3, the impact weight corresponding to the video service is 0.8, the impact weight corresponding to the data synchronization service is 0.6, and so on. Different types of control signaling can also correspond to different impact weights. For example, as the signaling size gradually decreases from the high layer to the physical layer, there can be: the impact weight corresponding to the high-level control signaling is 0.4, the impact weight corresponding to the middle-level control signaling is 0.3, and the impact weight corresponding to the middle-level control signaling is 0.2. It can also be understood that compared with the summation method, weighting can accurately reflect the overall impact of the service or control signaling. In addition, the weights of the impact weights corresponding to each service or control signaling can be the same when weighted. On this basis, the first terminal performs weighted summation of the first weighted value mean and the second weighted value mean to obtain the network influence factor of the second terminal.

[0054] S202: The first terminal updates terminals connected to the first terminal to N+1 terminals, where the N+1 terminals include the first terminal and N terminals.

[0055] S203: The first terminal allocates respective transmission resources to N+1 terminals according to the network impact factor of the second terminal.

[0056] The first terminal pre-stores the network influence factors of N terminals, a total of N network influence factors, and the network influence factors of the N terminals can be determined in a manner similar to the network influence factor of the second terminal described above. The network influence factor of the second terminal and the N network influence factors total N+1 network influence factors. On this basis, the first terminal performs the following operations:

[0057] The first terminal may sum up the N+1 network impact factors to obtain a total value of the network impact factors.

[0058] The first terminal can allocate corresponding transmission resources to N+1 terminals in the side transmission resource pool according to the proportion of each of the N+1 terminals' network impact factors in the total value of the network impact factors, and the proportion of the transmission resources of each of the N+1 terminals in the side transmission resource pool is the same as the proportion of the network impact factor of the terminal in the total value of the network impact factors. For example, the side transmission resource pool of the first terminal is a frequency domain transmission resource pool with continuous frequency domain transmission resources (such as a continuous plurality of subcarriers, carriers, partial bandwidths, bandwidths, etc.), and the first terminal can allocate domain transmission resources at a certain granularity (such as subcarriers / carriers / partial bandwidths / bandwidths, etc.), such as allocating continuous one or more subcarriers / carriers / partial bandwidths / bandwidths, etc. On this basis, the first terminal can sort the N+1 terminals according to the distance relationship between the respective positions of the N+1 terminals to obtain the resource allocation order of the N+1 terminals.

[0059] Specifically, the first terminal may instruct N+1 terminals to provide their respective locations, wherein each of the N+1 terminals may be positioned (specifically, it may be implemented in an existing manner), or obtain their respective locations (specifically, they may be latitude and longitude coordinates) from other devices (such as a positioning management function network element in the network). In this way, the first terminal determines the two terminals with the farthest distance from each other among the N+1 terminals according to the respective locations of the N+1 terminals, and determines the first resource allocation order between the two terminals. In addition to the first two terminals, the N+1 terminals also include N-1 terminals, and the terminal with the later order in the first resource allocation order is determined as the first target terminal. For example, the two terminals include terminal #1 and terminal #2, and the first terminal may determine that the sum of the distances between one of the two terminals and the N-1 terminals is the first distance value, and the sum of the distances between the other of the two terminals and the N-1 terminals is the second distance value; the first terminal may sort the two terminals in the order from large to small between the first distance value and the second distance value to obtain the first resource allocation order. Afterwards, the first terminal can determine a second target terminal farthest from the first target terminal from the N-1 terminals according to the respective positions of the N-1 terminals and the position of the first target terminal, and add the second target terminal to the end of the first resource allocation order to obtain a second resource allocation order. The N+1 terminals include N-2 terminals in addition to the first two terminals and the second target terminal. Afterwards, the first terminal can also determine a third target terminal farthest from the second target terminal from the N-2 terminals according to the respective positions of the N-2 terminals and the position of the second target terminal, and add the third target terminal to the end of the second resource allocation order to obtain a third resource allocation order. And so on, until the resource allocation order of the N+1 terminals is determined.

[0060] For ease of understanding, the following is an example. Figure 4 As shown, N+1 terminals include terminal A, terminal B, terminal C, and terminal D, wherein the two terminals farthest from each other are terminal A and terminal D. At this time, the sum of the distance between terminal D and terminal B and the distance between terminal D and terminal C is L1, and the sum of the distance between terminal A and terminal B and the distance between terminal A and terminal C is L2. L1 is greater than L2, indicating that the position of terminal D is more discrete and needs to be allocated transmission resources with the highest priority. At this time, the first resource allocation order is terminal D→terminal A. Among terminal B and terminal C, terminal C is farther from terminal A, so the second resource allocation order is terminal D→terminal A→terminal C, and finally the third resource allocation order is terminal D→terminal A→terminal C→terminal B. This can smoothly determine the position of frequency domain resources, thereby effectively avoiding resource interference caused by close physical locations.

[0061] Finally, the first terminal can allocate frequency domain transmission resources of each N+1 terminal in the frequency domain transmission resource pool in accordance with the proportion of each network impact factor of the N+1 terminals in the total value of the network impact factor and the resource allocation order of the N+1 terminals, and the proportion of the frequency domain transmission resources of each terminal in the side transmission resource pool is the same as the proportion of the network impact factor of the terminal in the total value of the network impact factor. The order of allocating frequency domain resources in the frequency domain transmission resource pool is the order of increasing frequency or the order of decreasing frequency.

[0062] For ease of understanding, continue with the above example, such as Figure 4 As shown, assuming that the proportion of the network impact factor of terminal D in the total value of the network impact factor is 0.4, which is recorded as the proportion of terminal D is 0.4, the same below, and no further description is given. The proportion of terminal A is 0.1, the proportion of terminal C is 0.3, and the proportion of terminal B is 0.2. Then the frequency domain transmission resources allocated by the frequency domain transmission resource pool are in the order of terminal D→terminal A→terminal C→terminal B, from top to bottom, the frequency domain transmission resources of terminal D, the frequency domain transmission resources of terminal A, the frequency domain transmission resources of terminal C, and the frequency domain transmission resources of terminal B, and the proportions of these resources in the frequency domain transmission resource pool are the same as the proportions of these terminals. It can be understood that each dynamic resource allocation must allocate all the frequency domain transmission resources in the frequency domain transmission resource pool in proportion.

[0063] It can also be understood that if the number of terminals connected to the first terminal decreases, the first terminal also needs to reallocate transmission resources. The principle is similar to the above and is also allocated proportionally, which will not be repeated here.

[0064] This application is frequency division multiplexing, so the allocation of time domain resources is not considered.

[0065] In summary, when the second terminal joins the Internet of Things system by establishing a connection with the first terminal, the first terminal determines the network impact factor of the second terminal, that is, the impact of the second terminal joining the establishment of the first terminal on the communication between the first terminal and the other N terminals. On this basis, the first terminal updates the terminals connected to the first terminal to N+1 terminals, that is, the N+1 terminals include the first terminal and the N terminals, and according to the network impact factor of the second terminal, comprehensively allocates respective transmission resources to the N+1 terminals, so that the transmission resources can match their respective network impact factors, that is, the transmission stability of large-scale Internet of Things scenarios is guaranteed through dynamic resource allocation.
