[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, each embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be understood by those skilled in the art that in each embodiment of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with each other and referenced to each other under the premise that there is no contradiction.

[0027] The first embodiment of the present invention relates to a self-organizing network method, which can be applied to a central device. In a wireless communication network, the central device generally refers to a core device or a central control device in the network, which is responsible for managing and controlling the operation and data traffic of the entire network. For example, the central device can be a device such as a router, a switch or a controller. The central device and multiple peripheral devices form a one-to-many network topology structure. In the network topology structure, the scheduling time for the central device to interact with multiple peripheral devices is divided into multiple time groups, and a time group includes multiple time slots. The peripheral device refers to an auxiliary device or terminal device connected to the central device, which is used to implement a specific function or provide a specific service. For example, terminal devices such as computers and mobile phones, sensors, execution devices or storage devices. In this embodiment, the central device sends network status information before the first time slot in each time group. The new peripheral device selects an idle time slot based on the network status information and sends a network access request response packet to the central device within the idle time slot. After the central device receives the network access request response packet returned by the new peripheral device within the idle time slot, it sends a network access response confirmation packet to the new peripheral device within the idle time slot. This allows for the rapid allocation of idle time slots for the newly joined peripheral device, adding the new peripheral device to the network, and allocating a dedicated time slot for the new peripheral device to communicate with the central device, thereby improving the efficiency of wireless communication network formation. The following describes the implementation details of the networking method of this embodiment in detail. The following content is merely provided for ease of understanding and is not required for the implementation of this solution.

[0028] As shown in FIG1 , in step 101 , network status information is sent before the first time slot in each time group.

[0029] In a wireless communication network, a time group refers to the division of the scheduled time for interaction between a central device and multiple peripheral devices into different intervals, with each interval being allocated to multiple different peripheral devices for interaction with the central device. Typically, each time group includes multiple time slots, each of which is a smaller time period within the corresponding time group. Typically, a time slot is allocated to a specific peripheral device for interaction with the central device. Utilizing these time groups and time slots, different peripheral devices can interact and communicate with the central device in specific time slots within different time groups, effectively allocating communication resources in the wireless communication network and avoiding interference and collisions between other peripheral devices and the central device.

[0030] When the central device is in a state where networking is allowed, that is, when there is no data to be transmitted in the wireless communication network where the central device is located, the central device sends network status information before the first time slot in each time group. The network status information includes idle or occupied status information of each time slot in each time group of the wireless communication network where the central device is located. By sending the network status information externally, new peripheral devices that need to join the network are notified to prepare for network access, because time groups and time slots can determine the network position of a peripheral device. When a time slot is idle, it means that the network position corresponding to the idle time slot is idle, and the new peripheral device can occupy the idle network position, thereby joining the network where the central device is located.

[0031] In one example, the central device transmits the network status information using a synchronization packet. The synchronization packet specifies the current network operation function. Specifically, the central device transmits at least one synchronization packet with an operation code of the networking type within each time group (as shown in FIG. 2 ). The synchronization packet carries the network status information, including the number of time slots in the current time group, the time slot duration, and the idle state of each time slot.

[0032] In step 102, after receiving the network access request response packet returned by the new peripheral device in the idle time slot, a network access response confirmation packet is sent to the new peripheral device in the idle time slot, wherein the idle time slot is a time slot selected by the new peripheral device according to the network status information for interacting with the central device.

[0033] The network access request response packet returned by the new peripheral device and received by the central device includes a network access request message (as shown in FIG2 ). The network access request message includes the peripheral device address, a time slot number, and a specific operation code. The time slot number indicates the identifier of an idle time slot selected by the new peripheral device based on the network status information. The specific operation code indicates the operation type corresponding to the new peripheral device, such as a network access application.

[0034] In one example, the central device checks whether the time slot corresponding to the network access request response packet returned by the new peripheral device is idle. If the time slot is idle, it sends a network access response confirmation packet to the new peripheral device, thereby adding the new peripheral device to the corresponding network. Typically, the network access response confirmation packet includes the central device address and the corresponding new peripheral device address.

[0035] In this embodiment, the central device transmits network status information before the first time slot in each time group. The central device receives a network access request response packet from the new peripheral device in an idle time slot selected based on the network status information, and then sends a network access response confirmation packet to the new peripheral device in the idle time slot. This allows for the rapid allocation of idle time slots for newly added peripheral devices, allowing them to join the network and allocate dedicated time slots for communication with the central device, thereby improving the efficiency of wireless communication network construction.

[0036] In the second embodiment of the present invention, after the new peripheral device joins the wireless communication network where the central device is located, when the wireless communication network is in an idle state, that is, the central device and the peripheral device have no data transmission requirements, each of the peripheral devices may not send a response packet to the central device in the time slot corresponding to the peripheral device in order to maintain low power consumption. At this time, the peripheral device is in a stealth state. The central device can use the quick roll call function to enable all the peripheral devices in a stealth state in a certain time group to respond to the central device, so as to update the status of the wireless communication network in real time. Specifically, as shown in Figure 3, before the first time slot in each time group, the central device sends a synchronization data packet with an operation code of the quick roll call type, and in the specific time slot corresponding to each peripheral device, after receiving the roll call response packet of the synchronization data packet of the quick roll call type returned by the corresponding peripheral device, it sends a roll call response confirmation packet to the corresponding peripheral device in the specific time slot.

[0037] In a third embodiment of the present invention, after a new peripheral device joins the wireless communication network where the central device resides, the central device utilizes the unicast data transmission function to perform a data transmission to a single peripheral device via a specific time slot corresponding to the peripheral device. Specifically, as shown in FIG4 , before the first time slot in each time group, the central device transmits a synchronization data packet with an operation code of unicast data transmission type. Within a specific time slot within each time group, upon receiving a unicast response packet indicating receipt of a synchronization data packet of unicast data transmission type from the corresponding peripheral device, the central device then transmits a unicast response confirmation packet to the corresponding peripheral device within the specific time slot.

[0038] In a fourth embodiment of the present invention, after a new peripheral device joins the wireless communication network of a central device, the central device utilizes the multipoint data transmission function to perform a data transmission to multiple peripheral devices via specific time slots corresponding to each peripheral device. Specifically, as shown in FIG5 , before the first time slot in each time group, the central device transmits a synchronization data packet with an operation code of multipoint data transmission type. After receiving multipoint transmission response packets indicating receipt of synchronization data packets of multipoint data transmission type from corresponding peripheral devices within multiple specific time slots within each time group, the central device then transmits a multipoint transmission response confirmation packet to the corresponding peripheral device within each specific time slot.

[0039] In a fifth embodiment of the present invention, after a new peripheral device joins the wireless communication network where the central device resides, the central device utilizes the global data transmission function to perform a data transmission to all peripheral devices within the time group, using the specific time slot and time group corresponding to each peripheral device. Specifically, as shown in FIG6 , before the first time slot in each time group, the central device transmits a synchronization data packet with an operation code of the global data transmission type. Within each time slot within each time group, upon receiving a global transmission response packet indicating receipt of a synchronization data packet of the global data transmission type from the corresponding peripheral device, the central device then transmits a global transmission response confirmation packet to the corresponding peripheral device within each corresponding time slot.

[0040] Through the single-point data transmission function, multi-point data transmission function and overall data transmission function in the third, fourth and fifth embodiments of the present invention, diversified and rapid data interaction between the central device and the peripheral devices can be achieved.

[0041] The sixth embodiment of the present invention relates to a self-organizing network method that can be applied to new peripheral devices, wherein a central device and a plurality of networked peripheral devices form a one-to-many network topology structure, and in the network topology structure, the scheduling time for the networked peripheral devices to interact with the central device is divided into a plurality of time groups, and each time group includes a plurality of time slots. In the sixth embodiment, when the new peripheral device receives the network status information sent by the central device, it identifies an idle time slot from the network status information; within the idle time slot, it sends a network access request response packet to the central device, and receives a network access response confirmation packet returned by the central device, so that the new peripheral device can use the idle time slot to quickly join the network, thereby improving the efficiency of wireless communication network networking. The implementation details of the networking method of the sixth embodiment are described in detail below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0042] As shown in FIG7 , in step 201 , when network status information sent by the central device is received, an idle time slot is identified from the network status information.

[0043] Based on the embodiment of the networking method applied to the central device, after receiving the synchronization data packet, the new peripheral device identifies the idle time slot in the current time group from the network status information carried in the synchronization data packet.

[0044] In step 202, a network access request response packet is sent to the central device in the idle time slot, and a network access response confirmation packet returned by the central device is received.

[0045] The network access request response packet returned by the new peripheral device to the central device during the idle time slot includes network access request information (as shown in FIG2 ). The network access request information includes the peripheral device address, the time slot number, and a specific operation code. The time slot number indicates the identifier of the idle time slot selected by the new peripheral device based on the network status information. The specific operation code indicates the operation type corresponding to the new peripheral device, such as a network access application.

[0046] In this embodiment of the present invention, the central device transmits network status information before the first time slot in each time group. A new peripheral device selects an idle time slot based on the network status information and sends a network access request response packet to the central device within the idle time slot. After receiving the network access request response packet returned by the new peripheral device within the idle time slot, the central device sends a network access response confirmation packet to the new peripheral device within the idle time slot. This allows for the rapid allocation of idle time slots for the newly added peripheral device, adding the new peripheral device to the network, and allocating a dedicated time slot for the new peripheral device to communicate with the central device, thereby improving the efficiency of wireless communication network formation.

As long as they include the same logical relationship, they are all within the scope of protection of this patent.
