This technique may provide a low power, scalable long-range wireless network for battery-powered wireless devices.
The LoRa gateway is a communication base station in the LoRa wan, which is responsible for data transmission between the LoRa node and the LoRa core network.

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 LoRa wan, and may communicate with the LoRa gateway through the LoRa air interface, where the LoRa gateway may be connected to the LoRa core network by, but not limited to, wi-Fi, 4G, 5G, or wired network connection (such as ethernet), so as to uplink data sent by the LoRa node to the LoRa core network.
The LoRa core network refers to a core control unit of the LoRa network, and provides network management services, application management services, and the like. In the present 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 the LoRa wan, 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. A single channel LoRa gateway refers to a LoRa gateway having only one physical channel, and a multi-channel LoRa gateway refers to a LoRa gateway that supports multi-channel (typically at least 48 channels) communications. The price of the multi-channel LoRa gateway is far higher than that of the single-channel LoRa gateway, so that the single-channel LoRa gateway is adopted for networking due to cost consideration.
However, single channel LoRa gateways tend to be fixed on a particular channel when receiving/transmitting. The transmission characteristics of the LoRa network are that the transmission distance is relatively long, typically 1Km to 10Km. Assuming that too many single-channel LoRa gateways are concentrated in a certain area, all the single-channel LoRa gateways are concentrated on a plurality of channels for communication, signal interference can be caused among the gateways, and the communication quality of the whole network is affected.
Fig. 2 shows a schematic diagram of a network architecture consisting of a plurality of single channel LoRa gateways.
The dashed area around the single channel LoRa gateway in fig. 2 is used to represent the signal coverage area of the gateway, and the area where the coverage areas intersect is the signal overlap area. For two single channel LoRa gateways with signal overlap regions, if they operate on the same LoRa channel, communication of the LoRa nodes in the signal overlap region can cause interference between the gateways, affecting 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 parameters of the modulation of 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 the same LoRa spreading factor.
Therefore, the present disclosure proposes a networking (i.e., 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 flow
The networking process can be initiated by a single channel LoRa gateway. For example, when a new single-channel LoRa network is added in the network, a single-channel LoRa gateway sends a networking request to a network server; after receiving the 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 can also send the networking flow, for example, when the network is changed or the network needs to be optimized, the network server can actively initiate the networking flow to adjust the channels of one or more single-channel LoRa gateways in the network so as to optimize the channel allocation of the network. For example, the network server can send a networking request to a single channel LoRa gateway needing channel adjustment; and after receiving the networking request sent by the 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 chart 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, among other things.
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 web server.
The networking process is further described below 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 a plurality of LoRa channels, respectively, and the first LoRa data may be received by other LoRa gateways operating on the plurality of LoRa channels and uploaded to a web server.
As an example, the signal polarity at the time of reception by the LoRa gateway is negative, the signal polarity at the time of transmission by the LoRa gateway is positive, the signal polarity at the time of transmission by the LoRa node is negative, and the signal polarity at the time of reception by the LoRa node is positive. In the present disclosure, the single channel LoRa gateway may act as a "LoRa node" when networked, transmitting first LoRa data of negative polarity on multiple LoRa channels, respectively.
The first LoRa data is transmitted over a plurality of LoRa channels, respectively, i.e., the first LoRa data is transmitted over different LoRa frequency points and/or LoRa spreading factors. Wherein the first LoRa data may include channel information of a LoRa channel used at the time of transmission, e.g., the first LoRa data may include a LoRa frequency point and a LoRa spreading factor used at the time of transmission.
As an example, the 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" manner, and transmit the first LoRa data in a "frequency sweep" manner, that is, traverse all LoRa spreading factors under all LoRa frequency points, transmit the first LoRa data using different LoRa spreading factors under each LoRa frequency point, 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 there are other LoRa gateways operating on the corresponding LoRa channel nearby, the first LoRa data can be received by the other LoRa gateways. Here, other LoRa gateways, i.e. LoRa gateways present in the network, may refer to single channel LoRa gateways operating on a specific LoRa channel. For other LoRa gateways, the first LoRa data received by the other LoRa gateways is just like uplink data sent by a LoRa node in a network, so that the other LoRa gateways can upload the first LoRa data to a network server after receiving the first LoRa data.
When a single channel LoRa gateway transmits first LoRa data on a certain LoRa channel, if there are no other LoRa gateways operating on the corresponding LoRa channel nearby, the first LoRa data cannot be received by the other LoRa gateways, and the first LoRa data cannot reach the network server.
Referring to fig. 4, in step S210, the web 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 is received by the network server, so that other LoRa gateways working on the LoRa channel exist nearby the single-channel LoRa gateway, namely, 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, which is not received by the network server, and indicates that other LoRa gateways working on the LoRa channel do not exist near the single-channel LoRa gateway, that is, the LoRa channel is an interference-free LoRa channel which is not needed to be avoided (i.e. can be selected) when the network server configures the LoRa channel for the single-channel LoRa gateway.
Therefore, the network server can set a proper LoRa channel for the single-channel LoRa gateway according to the receiving condition of the first LoRa data. That is, in step S220, a LoRa channel is configured for the single channel LoRa gateway according to the LoRa channel corresponding to the received first LoRa data.
As an example, if there is a non-interfering LoRa channel, the network server may preferentially configure the non-interfering channel for a single channel LoRa gateway.
If the first LoRa data transmitted by the single-channel LoRa gateway on all LoRa channels is received by the network server, it indicates that all LoRa channels are interference channels, at this time, the network server can determine the interference degree of the interference channels according to the number of the LoRa gateways working on the interference channels near the single-channel LoRa gateway, and then designates the interference channels with lower interference degrees (such as a first threshold) for the single-channel LoRa gateway. That is, if no interference-free LoRa channel is present, a LoRa channel with an interference level below a threshold (i.e., 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 web server may determine that the LoRa gateway is a suspected gateway having a signal overlapping region with the single-channel LoRa gateway, and thus may determine all suspected gateways in the vicinity of the single-channel LoRa gateway. And the network server may consider the LoRa channel of the suspected gateway as the suspected LoRa channel (corresponding to the interference channel mentioned above) that needs to be avoided. Thus, when the network server sets a proper LoRa channel for the single-channel LoRa gateway, the network server can preferentially select a LoRa channel which is not a suspected LoRa channel, and the LoRa channel can be regarded as an interference-free channel. In addition, the network server can also judge the interference degree of the suspected LoRa channel according to the number of the suspected gateways working on the same suspected LoRa channel, wherein the interference degree is positively correlated with the number, that is, the more the number is, the more serious the interference degree is, so that if all the LoRa channels are suspected LoRa channels, that is, no available interference-free channels are available, the suspected LoRa channels with relatively lower interference degree can be designated for the single-channel LoRa gateway.
For another example, the first LoRa data may include channel information for a LoRa channel used when the single channel LoRa gateway transmits. The network server can judge the LoRa channel represented by the channel information in the received first LoRa data as an interference channel, so that when the network server sets a proper LoRa channel for the single-channel LoRa gateway, the network server can preferentially select an interference-free channel which does not belong to the interference channel. In addition, the network server can also determine the interference degree of the LoRa channel corresponding to the first LoRa data according to the number of the LoRa gateways uploading the same first LoRa data, wherein the interference degree is positively correlated with the number, that is, the more the number is, the more serious the interference degree is, so that if all the available LoRa channels are interference LoRa channels, that is, no interference channels are available, then a LoRa channel with relatively low interference degree (such as lower than a threshold value) can be designated for the single-channel LoRa gateway.
Optionally, when the LoRa channel is configured for the LoRa gateway, the LoRa channel capable of meeting specific requirements can be configured for the LoRa gateway according to actual requirements. For example, in the case where an exclusive channel is required for a LoRa gateway, the LoRa channel configured for the LoRa gateway is not open to other LoRa gateways. For another example, when the LoRa gateway needs to protect the adjacent frequency points, it is possible to control that the frequency points corresponding to the LoRa channel configured for the LoRa gateway and the adjacent frequency points are not open to other LoRa gateways.
In step S230, after configuring the single-channel LoRa gateway with the LoRa channel, the web 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, the second LoRa data including channel information for a LoRa channel configured for the single channel LoRa gateway. The configuration process of the LoRa channel in the second LoRa data according to the LoRa channel configuration corresponding to the first LoRa data received by the network server may be described above.
In step S130, after receiving the second LoRa data sent by the network server, the single-channel LoRa gateway may be configured to operate on the LoRa channel characterized by the channel information in the second LoRa data, thereby fixing the single-channel LoRa gateway on the interference-free 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 gateway 01, gateway 02, and gateway 03 are existing gateways of the current network, gateway 01 operates on channel 1, gateway 02 operates on channel 2, gateway 03 operates on channel 3, and a 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.
The single channel LoRa gateway then transmits first LoRa data of negative polarity on all channels, wherein gateway 01, gateway 02, gateway 03 can all receive the first LoRa data and report the first LoRa data to the web server.
After the single-channel LoRa gateway performs one-round scanning transmission on all channels, the network server can judge the interference-free channels around the single-channel LoRa gateway according to the channel information attached to the received first LoRa data, so that the network server can assign the interference-free channels to the single-channel LoRa gateway as the LoRa channels when the single-channel LoRa gateway works, and send second LoRa data containing the assigned channels to the single-channel LoRa gateway so as to fix the single-channel LoRa gateway on the assigned channels, for example, the network server can fix the single-channel LoRa gateway on the channel 4.
Fig. 6 shows a schematic flow chart of a LoRa network access method according to an embodiment of the disclosure. Wherein the method shown in fig. 6 may be performed by a web server
Referring to fig. 6, in step S310, a networking request sent by the LoRa gateway is received. The LoRa gateway may refer to a single channel LoRa gateway as described above.
In step S320, a channel is allocated for the LoRa gateway.
The LoRa gateway can be assigned a channel according to the networking method described above. The difference is that a LoRa channel that can meet specific requirements can be configured for the LoRa gateway. For example, in the case where an exclusive channel is required for a LoRa gateway, the LoRa channel configured for the LoRa gateway is not open to other LoRa gateways. For another example, when the LoRa gateway needs to protect the adjacent frequency points, it is possible to control that the frequency points corresponding to the LoRa channel configured for the LoRa gateway and the adjacent frequency points are not open to other LoRa gateways.
At step S330, the LoRa data is sent to the LoRa gateway, the LoRa data including channel information of the LoRa channel allocated for the LoRa gateway.

The transmitting module 710 is configured to transmit first ra data on a plurality of ra channels, respectively, where the first ra data is received by other ra gateways operating on the plurality of ra channels and uploaded to the network server, that is, the other ra gateways operating on the corresponding ra channels receive the first ra data and upload the first ra data to the network server. For the first LoRa data, see the relevant description above, and will not be repeated here.
