Detailed Description
Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a schematic diagram of a LoRa network topology.
As shown in fig. 1, the LoRa node is a node device in the LoRaWAN, and may communicate with the LoRa gateway through an LoRa air interface, and the LoRa gateway may be connected to the LoRa core network through, but not limited to, Wi-Fi, 4G, 5G, or wired network connection (e.g., ethernet), so as to uplink data sent by the LoRa node to the LoRa core network.
The LoRa core network is a core control unit of the LoRa network, and provides network management services, application management services, and the like. In this disclosure, the LoRa core Network mainly refers to a Network Server (NS for short), and the LoRa gateway is connected to the LoRa core Network, that is, connected to the Network Server.
The LoRa gateway is a communication base station in LoRaWAN which is responsible for data transmission between the LoRa node and the network server. The LoRa gateway is divided into a single-channel gateway and a multi-channel gateway. The single-channel LoRa gateway is an LoRa gateway having only one physical channel, and the multi-channel LoRa gateway is an LoRa gateway supporting multi-channel (usually, at least 48 channels) communication. The price of the multi-channel LoRa gateway is far higher than that of a single-channel LoRa gateway, so that the single-channel LoRa gateway can be adopted for networking due to cost.
However, the single-channel LoRa gateway is often fixed on a specific channel when receiving/transmitting. The transmission characteristic of the LoRa network is that the transmission distance is long, and is usually 1Km to 10 Km. If too many single-channel LoRa gateways are concentrated in a certain area, and all the single-channel LoRa gateways are concentrated on several channels for communication, signal interference may occur between the gateways, and the communication quality of the whole network may be affected.
Fig. 2 shows a schematic diagram of a network structure composed of multiple single-channel LoRa gateways.
The dotted line area at the periphery of the single-channel LoRa gateway in fig. 2 is used to indicate the signal coverage area of the gateway, and the area where the coverage areas intersect is the signal overlapping area. For two single-channel LoRa gateways with signal overlapping regions, if they work on the same LoRa channel, the communication of LoRa nodes in the signal overlapping regions may cause interference between gateways, which affects gateway stability. As shown in fig. 2, if the single-channel LoRa gateway 01 and the single-channel LoRa gateway 02 operate on the same LoRa channel, interference may occur between the single-channel LoRa gateway 01 and the single-channel LoRa gateway 02.
The LoRa channel refers to an air interface channel with a fixed LoRa frequency point and a fixed LoRa spreading factor. The LoRa frequency point refers to the center frequency and bandwidth of LoRa air interface transmission. The LoRa spreading factor refers to the spreading parameter modulated by the LoRa signal. The LoRa signals modulated by different LoRa spreading factors under the same LoRa frequency point can not interfere with each other, and the same LoRa channel refers to the LoRa channel with the same LoRa frequency point and LoRa spreading factor.
Therefore, the present disclosure provides a networking (also referred to as network access) scheme capable of reducing interference between single-channel LoRa gateways, and a networking flow of the single-channel LoRa gateways is as follows.
1. Initiation of networking procedures
The networking process may be initiated by a single channel LoRa gateway. For example, when a new single-channel LoRa network is added to the network, a single-channel LoRa gateway sends a networking request to a network server; after receiving a networking request sent by the single-channel LoRa gateway, the network server can send a networking response aiming at the networking request to the single-channel LoRa gateway; and after receiving the networking response, the single-channel LoRa gateway enters a subsequent networking process.
The network server may also send a networking procedure, for example, when the network changes or needs to be optimized, the network server may actively initiate the networking procedure to adjust channels of one or more single-channel LoRa gateways existing in the network, so as to optimize channel allocation of the network. For example, a network server may send a networking request to a single-channel LoRa gateway that needs to adjust a channel; after receiving a networking request sent by a network server, the single-channel LoRa gateway sends a networking response to the network server and enters a subsequent networking process.
2. Networking process
Fig. 3 shows a schematic flow diagram of a networking method of a single-channel LoRa gateway according to one embodiment of the present disclosure. The method shown in fig. 3 may be performed by a single-channel LoRa gateway.
Fig. 4 shows a schematic flow chart of a networking method of a single-channel LoRa gateway according to one embodiment of the present disclosure. Wherein the method shown in fig. 4 may be performed by a network server.
The networking process is further described with reference to fig. 3 and 4.
Referring to fig. 3, in step S110, the single-channel LoRa gateway is controlled to transmit first LoRa data on the plurality of LoRa channels, and the first LoRa data may be received by other LoRa gateways operating on the plurality of LoRa channels and uploaded to the network server.
As an example, the polarity of the signal is negative when the LoRa gateway receives, positive when the LoRa gateway transmits, negative when the LoRa node transmits, and positive when the LoRa node receives. In this disclosure, the single-channel LoRa gateway may serve as a "LoRa node" when networking, and respectively transmit the first LoRa data with negative polarity on a plurality of LoRa channels.
And respectively transmitting the first LoRa data on the plurality of LoRa channels, namely transmitting the first LoRa data through different LoRa frequency points and/or LoRa spreading factors. The first LoRa data may include channel information of an LoRa channel used in transmission, for example, the first LoRa data may include LoRa frequency bins and LoRa spreading factors used in transmission.
As an example, a single-channel LoRa gateway may traverse all LoRa channels, transmitting at least one first LoRa data on each LoRa channel. That is, the single-channel LoRa gateway can transmit the first LoRa data in a frequency sweep mode, and transmit the first LoRa data in a frequency sweep mode, that is, traverse all the LoRa spreading factors under all the LoRa frequency points, use different LoRa spreading factors under each LoRa frequency point to transmit the first LoRa data, and the channel information in the transmitted first LoRa data can also be regarded as frequency sweep information, that is, the LoRa frequency points and the LoRa spreading factors used during frequency sweep.
When a single-channel LoRa gateway transmits first LoRa data on a certain LoRa channel, if other LoRa gateways working on the corresponding LoRa channel exist nearby, the first LoRa data can be received by other LoRa gateways. Here, the other LoRa gateways are also LoRa gateways existing in the network, and the LoRa gateway may refer to a single-channel LoRa gateway operating on a specific LoRa channel. For other LoRa gateways, the received first LoRa data is just the uplink data sent by the LoRa node in the network, and therefore the other LoRa gateways upload the first LoRa data to the network server after receiving the first LoRa data.
When a single-channel LoRa gateway transmits first LoRa data on a certain LoRa channel, if other LoRa gateways working on the corresponding LoRa channel do not exist nearby, the first LoRa data cannot be received by other LoRa gateways, and the first LoRa data cannot reach a network server.
Referring to fig. 4, in step S210, the network server may receive first LoRa data uploaded by one or more LoRa gateways.
The single-channel LoRa gateway transmits first LoRa data on a certain LoRa channel, and the first LoRa data are received by the network server, so that other LoRa gateways working on the LoRa channel exist near the single-channel LoRa gateway, and the LoRa channel is an interference channel which needs to be avoided when the network server configures the LoRa channel for the single-channel LoRa gateway.
The single-channel LoRa gateway transmits first LoRa data on a certain LoRa channel, and the first LoRa data are not received by the network server, which indicates that no other LoRa gateway working on the LoRa channel exists near the single-channel LoRa gateway, that is, the LoRa channel is a non-interference LoRa channel which does not need to be avoided (can be selected for use) when the network server configures the LoRa channel for the single-channel LoRa gateway.
Therefore, the network server can set an appropriate LoRa channel for the single-channel LoRa gateway according to the receiving condition of the first LoRa data. That is, in step S220, according to the LoRa channel corresponding to the received first LoRa data, the LoRa channel is configured for the single-channel LoRa gateway.
As an example, if there is a clear LoRa channel, the network server may preferentially configure the clear channel for the single-channel LoRa gateway.
If the first LoRa data transmitted by the single-channel LoRa gateway on all LoRa channels are received by the network server, it indicates that all LoRa channels are interference channels, and at this time, the network server may determine the interference degree of the interference channel according to the number of LoRa gateways working on the interference channel near the single-channel LoRa gateway, and then designate the interference channel with a lower interference degree (e.g., a first threshold value) for the single-channel LoRa gateway. That is, if there is no interference-free LoRa channel, an LoRa channel with an interference degree lower than a threshold (that is, a weak interference LoRa channel) may be configured for the single-channel gateway.
For example, after receiving the first LoRa data uploaded by the LoRa gateway, the network server may determine that the LoRa gateway is a suspected gateway having a signal overlapping area with the single-channel LoRa gateway, so that all suspected gateways near the single-channel LoRa gateway may be determined. And the network server may use the LoRa channel of the suspected gateway as the suspected LoRa channel (corresponding to the interference channel mentioned above) to be avoided. Therefore, when the network server sets a proper LoRa channel for the single-channel LoRa gateway, the LoRa channel which is not the suspected LoRa channel can be preferentially selected, and the LoRa channel can be regarded as a non-interference channel. In addition, the network server can also determine the interference degree of the suspected LoRa channel according to the number of suspected gateways working on the same suspected LoRa channel, wherein the interference degree is positively correlated with the number, that is, the interference degree is more serious when the number is larger, so that if all the LoRa channels are suspected LoRa channels, that is, no available interference-free channel exists, the suspected LoRa channel with relatively low interference degree can be specified for the single-channel LoRa gateway.
As another example, the first LoRa data may include channel information of an LoRa channel used when the single-channel LoRa gateway transmits. The network server may determine the LoRa channel represented by the channel information in the received first LoRa data as an interference channel, and thus, when setting a suitable LoRa channel for the single-channel LoRa gateway, the network server may preferentially select a non-interference channel that does not belong to the interference channel. In addition, the network server may further determine, according to the number of the LoRa gateways uploading the same first LoRa data, an interference degree of the LoRa channel corresponding to the first LoRa data, where the interference degree is positively correlated with the number, that is, the interference degree is more serious when the number is larger, and thus, if all available LoRa channels are interfering LoRa channels, that is, there is no available interference-free channel, an LoRa channel with a relatively low interference degree (for example, lower than a threshold) may be specified for the single-channel LoRa gateway.
Optionally, when configuring the LoRa channel for the LoRa gateway, the LoRa channel capable of meeting specific requirements may be configured for the LoRa gateway according to actual requirements. For example, when the LoRa gateway needs an exclusive channel, the LoRa channel configured for the LoRa gateway is not opened to other LoRa gateways. For another example, when the LoRa gateway needs to protect adjacent frequency points, the frequency point corresponding to the LoRa channel configured for the LoRa gateway and the adjacent frequency point may not be open to other LoRa gateways.
In step S230, after configuring the LoRa channel for the single-channel LoRa gateway, the network server may send second LoRa data to the single-channel LoRa gateway, where the second LoRa data includes channel information of the LoRa channel set for the single-channel LoRa gateway.
In step S120, the single-channel LoRa gateway may receive second LoRa data sent by the web server, where the second LoRa data includes channel information of an LoRa channel configured for the single-channel LoRa gateway. The LoRa channel in the second LoRa data is configured according to the LoRa channel corresponding to the first LoRa data received by the network server, and the specific configuration process may refer to the above description.
In step S130, after receiving the second LoRa data sent by the network server, the one-channel LoRa gateway may be configured to operate on the LoRa channel represented by the channel information in the second LoRa data, so that the one-channel LoRa gateway may be fixed on the non-interference or weak-interference channel.
Fig. 5 shows a networking flow diagram of a single-channel LoRa gateway according to an embodiment of the present disclosure.
In this embodiment, it is assumed that the gateway 01, the gateway 02, and the gateway 03 are existing gateways of a current network, the gateway 01 operates in the channel 1, the gateway 02 operates in the channel 2, the gateway 03 operates in the channel 3, and the single-channel LoRa gateway is a newly added device.
As shown in fig. 5, the single-channel LoRa gateway first sends a networking request to the network server, and the network server sends a networking response to the single-channel LoRa gateway after receiving the message.
And then the single-channel LoRa gateway transmits first LoRa data with negative polarity on all channels, wherein the gateway 01, the gateway 02 and the gateway 03 can receive the first LoRa data and report the first LoRa data to the network server.
After the single-channel LoRa gateway performs one-round scanning emission on all channels, the network server can judge the non-interference channels around the single-channel LoRa gateway according to the received channel information attached to the first LoRa data, so that the network server can designate the non-interference channels as the LoRa channels during the operation of the single-channel LoRa gateway, and send second LoRa data containing the designated channels to the single-channel LoRa gateway, so that the single-channel LoRa gateway is fixed on the designated channels, such as the channel 4.
Fig. 6 shows a schematic flow chart of a LoRa network access method according to an embodiment of the present disclosure. Wherein the method shown in FIG. 6 may be performed by a network server
Referring to fig. 6, in step S310, a networking request sent by the LoRa gateway is received. Wherein, the LoRa gateway may refer to the single-channel LoRa gateway mentioned above.
In step S320, a channel is allocated for the LoRa gateway.
The channels may be allocated to the LoRa gateways according to the networking method described above. The difference is that the LoRa channel that can meet specific requirements can be configured for the LoRa gateway. For example, when the LoRa gateway needs an exclusive channel, the LoRa channel configured for the LoRa gateway is not opened to other LoRa gateways. For another example, when the LoRa gateway needs to protect adjacent frequency points, the frequency point corresponding to the LoRa channel configured for the LoRa gateway and the adjacent frequency point may not be open to other LoRa gateways.
In step S330, LoRa data including channel information of the LoRa channel allocated to the LoRa gateway is transmitted to the LoRa gateway.
