[0002] Multi-hop network, also known as multi-hop communication or relay communication, refers to the forwarding of data from the source node to the destination node through multiple intermediate nodes in network communication. Each intermediate node not only receives data, but also is responsible for passing the data to the next node until the data finally reaches the destination node.

[0003] Most of the existing multi-hop networks focus on routing, require very professional configuration parameters, and need network coordinators to solve network initialization and access problems. They are not friendly to deployment and device access support.

[0028] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] Figure 1 FIG. 1 is a flow chart of a Turmass same-frequency multi-hop method provided by an embodiment of the present invention. Figure 1 As shown, it is characterized by comprising:

[0030] 101. A communication network is composed of a plurality of network nodes;

[0031] 102. Based on the TDD frame mode of Turmass, each node performs signaling interaction through multiple hops in a decentralized manner to transmit data to the destination address.

[0032] It should be noted that the node module is in Slave time slot mode by default when it leaves the factory. When the device needs to send data, it changes the time slot frame composition and processes the received data based on whether multi-hop is enabled.

[0033] Specifically, Figure 2 is a multi-hop schematic diagram provided by an embodiment of the present invention, such as Figure 2 As shown, in step 101, the communication network provided by the embodiment of the present invention is formed by various nodes, and the functions of various nodes are independent and can be dormant.

[0034] In step 102, when data needs to be transmitted, the time slot mode is changed by changing the composition of the time slot frame, and multi-hop transmission is further performed. This process is mainly implemented based on the TDD frame mode of Turmass.

[0035] Some specific explanations include:

[0036] TDD: A frame can be divided into N subframes, each of which can be set to Tx, Rx, IDLE or BCN (synchronous frame) mode.

[0037] The Master is responsible for periodic operation of TDD, with the Tx subframe sending data and the Rx subframe receiving data at all times. The IDLE subframe is where the radio is idle.

[0038] Relay: Receive data and forward data.

[0039] The present invention provides a Turmass-based same-frequency multi-hop method and system, which uses Turmass's TDD frame mode to implement single-module same-frequency multi-hop transmission. The method provided by the present invention has lower cost, can implement single-antenna data stream transmission within a certain period of time, and utilizes multi-hop to achieve farther transmission and a larger signal coverage range.

[0040] In the Turmass-based TDD frame mode based on the above embodiment, each node performs signaling interaction through multi-hop in a decentralized manner, specifically including:

[0041] The communication module is configured as a slave time slot mode, and the node operates in a slave mode;

[0042] When there is data to be transmitted, the node switches to the main mode;

[0043] When a device receives data and needs to forward said data, it switches to relay mode.

[0044] It can be understood that the specific process of the method provided in the embodiment of the present invention is:

[0045] The communication module is factory configured in slave time slot mode, where the time slot is configured as follows:

[0046]

[0047] The node always runs in slave mode, and switches to master mode when there is data to be sent as follows:

[0048]

[0049] Among them, Tbcn is the time slot synchronization subframe of the module in the sending mode, which is used to synchronize all slave devices. Rbcn is the time slot synchronization subframe scanned by the slave module. After receiving the Tbcn subframe, the slave module can start subsequent data communication and interact with the master.

[0050] When the slave device receives data and needs to forward it, it switches to relay mode. The time slots of relay mode are as follows:

[0051]

[0052] After the device is synchronized by the Master, it receives data and sends a synchronization frame before forwarding to synchronize the modules in Slave mode. The Relay device is both a slave that receives data from other Masters and a Master that provides synchronization and sends data to more distant devices. Thus, same-frequency forwarding is achieved through time sharing.

[0053] From the above, it can be seen that the solution provided by the embodiment of the present invention does not have the concept of routing and coordinator, does not require full network synchronization, and is more suitable for the low-cost, low-speed transmission requirements of narrowband Internet of Things.

[0054] Based on the above embodiment, the method further includes:

[0055] The number of Rx, Tx, and subframes in the communication module is only limited by the rate transmission requirement.

[0056] In an embodiment of the present invention, the number of Rx, Tx, and subframes in the module can be arbitrarily combined as long as the data rate transmission requirements are met, wherein Tbcn in Relay must be after Rbcn, and there must be at least one Rx subframe between the two.

[0057] Based on the above embodiment, the method further includes:

[0058] In the relay mode, the time slot synchronization subframe of the module in the sending mode must be after the module scanning time slot synchronization subframe, and at least one Rx time slot is set between the Tbcn and the Rbcn.

[0059] It can be seen from the table of the above-mentioned Relay time slot that in the embodiment of the present invention, Tbcn in the Relay must be after Rbcn, and there must be at least one Rx subframe between the two.

[0060] Based on the above embodiment, the method further includes:

[0061] The node time slot includes an IDLE frame for reducing data interference and time slot protection between nodes, and the IDLE frame can be replaced by an RX or TX subframe.
