The LoRa is an ultra-long distance transmission scheme based on a spread spectrum technology in the Internet of things, and has the characteristics of long transmission distance, low power consumption, multiple nodes, low cost and the like.
The LoRa network comprises a terminal, a base station and a server. The working modes of the terminal comprise a ClassA mode, a ClassB mode and a ClassC mode. In the ClassB mode, the terminal will start a receive window, called a burst slot pintslot, for a predictable time.
The communication modes of the terminal include unicast and multicast. Unicast: the server configures a unique address identifier DebAddr for each terminal, and calculates the downlink frequency point and the time window of the Class B of the terminal according to the address. The server sends messages to the device separately at this frequency point and time window.
Multicast: the server configures a unique address identifier McAddr for each LoRa multicast group, and calculates the common Class B downlink frequency point and time window of a plurality of terminals in the multicast group according to the address. The server sends the message to all the terminals in the multicast group in the frequency point and the time window in a group mode.
When the terminal has two communication modes of unicast and multicast, the unicast address Pingslot and the multicast address Pingslot may overlap, but the unicast frequency point and the multicast frequency point are different, at this time, the terminal can only monitor the multicast/unicast frequency point fixedly, and the unicast/multicast downlink data is missed periodically, even the unicast/multicast downlink data can never be received.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a flowchart of a first step of an embodiment of a method for configuring an address of a terminal according to the present application is shown, which specifically includes the following steps:
in the embodiment of the present application, the terminal is a ClassB mode terminal. When the terminal accesses the network, the terminal sends an address configuration request to the gateway, and then the gateway forwards the address configuration request to the server.
Specifically, the server is deployed with an address allocator, and the address configuration request includes a terminal identifier DevEUI and a gateway identifier GWEUI.
The address allocator may determine which terminal sent the address configuration request according to the terminal identifier, and determine which gateway forwarded the address configuration request according to the gateway identifier.
102, selecting a target address from an address pool corresponding to the gateway, and configuring the target address to a terminal corresponding to the address configuration request, so that a multicast address and a unicast address of the terminal are located in the same address pool; and the pulse time slots PingSlot frequency points of the addresses of each address pool are the same.
In this embodiment of the present application, the address allocator may select at least one corresponding address pool for the gateway, where each address pool includes multiple addresses, where the PingSlot frequency points of addresses belonging to the same address pool are the same, and the PingSlot frequency points of addresses belonging to different address pools are different.
In the embodiment of the application, a target address can be selected from an address pool corresponding to a gateway, and the target address is configured for a terminal, so that a multicast address and a unicast address configured for the terminal are located in the same address pool, and since the pintslot frequency points of the addresses in the same address pool are the same, the frequency points of the multicast address and the unicast address are the same, and the condition that unicast downlink data or multicast downlink data is lost due to the fact that the frequency points of the multicast address and the unicast address are different does not occur.
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of an address configuration method for a terminal according to the present application is shown, which may specifically include the following steps:
in the embodiment of the present application, the terminal is a ClassB mode terminal. When the terminal accesses the network, the terminal sends an address configuration request to the gateway, and then the gateway forwards the address configuration request to the server.
Specifically, the server is deployed with an address allocator, and the address configuration request includes a terminal identifier DevEUI and a gateway identifier GWEUI.
The address allocator may determine which terminal sent the address configuration request according to the terminal identifier, and determine which gateway forwarded the address configuration request according to the gateway identifier.
The address allocator may determine, from a plurality of address pools that are preset, a corresponding address pool for a gateway to which the address configuration request corresponds.
Each address pool comprises a plurality of addresses, the PingSlot frequency points of the addresses belonging to the same address pool are the same, and the PingSlot frequency points of the addresses belonging to different address pools are different.
Referring to fig. 3, a schematic diagram of address pool partitioning in an embodiment of the present application is shown. The CN470 frequency band is a frequency band allocated to the chinese area, and all addresses in the frequency band may be divided into 8 address pools.
The address of the 1 st address pool may be represented as Nx8, the address of the 2 nd address pool may be represented as Nx8+ 1, the address of the 3 rd address pool may be represented as Nx8+ 2, the address of the 4 th address pool may be represented as Nx8+ 3, the address of the 5 th address pool may be represented as Nx8+ 4, the address of the 6 th address pool may be represented as Nx8+ 5, the address of the 7 th address pool may be represented as Nx8+ 6, and the address of the 8 th address pool may be represented as Nx8+ 7, N1, 2, … ….
In addition to dividing the CN470 frequency band into 8 address pools, the CN470 frequency band may be divided into other number of address pools; for example, if a network deploys gateways with 16 channels, the CN470 frequency band may be divided into 16 address pools; if a network deploys gateways with 32 channels, the CN470 frequency band may be divided into 32 address pools.
The division mode of the address pool can be determined according to actual conditions, which is not limited in the embodiment of the present application.
The formula for calculating the frequency point of the downlink channel of the Class B according to the unicast address under the CN470 frequency band is as follows:
the formula for calculating the frequency point of the downlink channel of the Class B according to the multicast address under the CN470 frequency band is as follows:
wherein, floor () is a function of rounding down, modulo is a modulo operation, beacon _ time is a beacon frame duration, and beacon _ period is a beacon frame period.
According to the two formulas, when the unicast address and the multicast address belong to the same address pool, the corresponding channel frequency points are the same.
In the embodiment of the present application, the step 202 may include the following sub-steps:
substep S11, determining the number of downlink channels of the gateway;
the address distributor can search the downlink channel number of the gateway from the database according to the gateway identifier in the address configuration request;
and a substep S12, determining an address pool corresponding to the gateway from a plurality of preset address pools according to the number of downlink channels of the gateway.
The address allocator may determine, according to the number of downlink channels of the gateway, an address pool corresponding to the gateway from among a plurality of address pools that are preset.
In an embodiment of the present application, the sub-step S12 may further include:
substep S121, if the number of the downlink channels of the gateway is one, determining an address pool corresponding to the gateway from a plurality of preset address pools;
substep S122, if the number of the downlink channels of the gateway is multiple, determining multiple address pools corresponding to the gateway from multiple preset address pools; and unused frequency points are arranged between every two address pools.
If the gateway has the capability of multiple downlink channels, a plurality of downlink physical frequency points are close to each other, and a large adjacent channel interference problem is generated. Adjacent channel interference is a common interference problem, and is generated not only in multi-channel multicast but also in multi-channel unicast downlink.
Therefore, in the embodiment of the present application, when the number of the downlink channels of the gateway is multiple, the address allocator may determine multiple corresponding address pools for the gateway, and the multiple address pools are separated by an unused frequency point, so that the downlink channels have a frequency interval, and the problem of adjacent channel interference is solved.
Referring to fig. 4, a schematic diagram of determining an address pool of a corresponding gateway in an embodiment of the present application is shown.
For a gateway with 1 downlink channel, the address pool No. 1 may be selected, and the unicast addresses and multicast addresses of all terminals within the service range of the gateway may be obtained from the address pool No. 1.
For a gateway with 2 downlink channels, address pools No. 1 and 5 can be selected, and the unicast address and the multicast address of all terminals in the service range of the gateway can be acquired from the two address pools.
For a gateway with 2 downlink channels, address pools of No. 1, No. 3, No. 5 and No. 7 can be selected, and unicast addresses and multicast addresses of all terminals in the service range of the gateway can be obtained from the four address pools.
In an embodiment of the present application, the address configuration request may include the type of address to be requested. Specifically, the address configuration request may include an address configuration request for a multicast address, an address configuration request for a unicast address, and an address configuration request for a unicast address and a multicast address.
The address configuration request aiming at the multicast address indicates that the terminal needs to request the multicast address, the address configuration request aiming at the unicast address indicates that the terminal needs to request the unicast address, and the address configuration request aiming at the unicast address and the multicast address indicates that the terminal needs to request the unicast address and the multicast address.
In an example of this embodiment of the application, the step 203 may include:
if the address configuration request is an address configuration request for a multicast address and the terminal has previously configured a unicast address, selecting an address from an address pool where the unicast address is located as a target address; and configuring the target address as the multicast address of the terminal.
And if the address configuration request is an address configuration request for a multicast address and the terminal is not configured with a unicast address in advance, selecting a target address from any address pool corresponding to the gateway and configuring the target address as the multicast address of the terminal.
In another example of the embodiment of the present application, the step 203 may include:
if the address configuration request is an address configuration request for a unicast address and the terminal has previously configured a multicast address, selecting an address from an address pool where the multicast address is located as a target address; and configuring the target address as a unicast address of the terminal.
If the address configuration request is an address configuration request for a unicast address and the terminal is not configured with a multicast address in advance, selecting a target address from any address pool corresponding to the gateway; and configuring the target address as a unicast address of the terminal.
In another example of the embodiment of the present application, the step 203 may include:
if the address configuration request is an address configuration request aiming at a unicast address and a multicast address, selecting two addresses from an address pool corresponding to the gateway as target addresses; and respectively configuring the target address as a unicast address and a multicast address of the terminal.
In the embodiment of the application, a target address can be selected from an address pool corresponding to a gateway, and the target address is configured for a terminal, so that a multicast address and a unicast address configured for the terminal are located in the same address pool, and since the pintslot frequency points of the addresses in the same address pool are the same, the frequency points of the multicast address and the unicast address are the same, and the condition that unicast downlink data or multicast downlink data is lost due to the fact that the frequency points of the multicast address and the unicast address are different does not occur.
