The preset port and the loopback interface can be set independently, and the setting mode comprises a plurality of modes such as network management remote configuration, local web configuration and local configuration files.
Further, the protocol conversion of the terminal data packet by the southbound interface module may be converting the terminal data packet originally based on the LoRaWan protocol into a terminal data packet based on the ieee802.3 protocol.
The transmission layer of the terminal data packet of the ieee802.3 Protocol follows UDP (User Datagram Protocol), and the application layer adopts JSON (JavaScript Object Notation) Protocol.
Further, the southbound interface module responds to the terminal forwarding module with a second ACK message when obtaining the network access request plaintext.
Specifically, a packet protocol of an MAC layer of the network access request message follows a LoRaWan protocol, a UDP protocol is adopted by a transmission layer, and a JSON protocol is adopted by an application layer;
the network access request message comprises three parameters of AppEII, DevEUI and DevNonce, wherein the AppEII is used for identifying a unique application provider, such as garbage can monitoring application, smoke alarm application and the like of each home, and has the unique AppEI which is a parameter preset in the terminal; DevEUI is used to identify a unique terminal, which may be the MAC address of the terminal; DevNonce is RSSI random value of LoRa chip in terminal;
the LoRaWan protocol stack module distributes the terminal address obtained according to DevEUI in the network access request message as DevAddr, the DevAddr, Appnnce and NetID generated during distribution form a network access response message, wherein the Appnnce is generated randomly, and the NetID functions like a subnet mask;
after receiving the network access response ciphertext, the terminal 102 extracts the DevAddr therein, and encrypts the DevAddr with aes128 by combining the AppKey, the AppNonce, the NetID and the DevNonce to generate 2 keys: NekSKey and AppSKey, the network access of the terminal 102 is completed. The NekSKey is used for encrypting and decrypting the terminal management message, and the AppSKey is used for encrypting and decrypting the terminal data message; the AppKey is shared by the terminal 102 and the gateway 104, is pre-stored in the terminal 102 and the gateway 104, and is used for encrypting and decrypting the network access response ciphertext and the network access request message.
The encryption and decryption adopt an AES128 mode, and the coding and decoding adopt a Base64 mode.
Specifically, the algorithm for allocating the terminal address is a simplified DHCPD (Dynamic Host Configuration Protocol (server) daemon) algorithm, and besides being used for realizing that the terminal address allocated according to the DevEUI is the DevAddr, the algorithm can also set the MAC address aging time of the gateway, so that the allocated terminal addresses do not overlap, and an address recovery mechanism without message exchange for a long time is realized through the MAC address aging time, so that the terminal 102 is prevented from occupying the DevAddr when the terminal is not online for a long time after being connected to the network.
It should be further noted that, since the transport layer of the management packet sent by the application server 106 adopts the UDP Protocol, the application layer adopts the JSON Protocol, and the LoRaWan Protocol specifies that the management packet sent to the Gateway by the LoRa network server follows the GWMP (LoRa Gateway Message Protocol), the LoRaWan Protocol stack module needs to parse the management packet, and the specific processing procedure includes: analyzing a first JSON load from the terminal management message to serve as terminal management data, and obtaining a terminal management analysis message based on the terminal management data; when the southbound interface module receives the PULL message, taking a terminal management analysis message as a PULL _ RESP message, and transmitting the PULL _ RESP message to the southbound interface module by the LoRaWan protocol stack module; wherein, the length of the PULL _ RESP message must not exceed 1000 octets. The specific treatment process further comprises the following steps: and analyzing the second JSON load from the gateway management message to obtain a gateway configuration instruction.
The southbound interface module mentioned in the above gateway receives the periodic pull message transmitted by the terminal forwarding module, which is actually equivalent to that the gateway sends the periodic pull message to the LoRa network server in the conventional LoRa network system shown in fig. 1 (the periodic pull message is used to keep the firewall of the LoRa network server in an open state), and can be autonomously set by combining with the preset port and the loopback interface and the southbound interface module responds to the terminal forwarding module with the second ACK message. In fact, the function of transmitting and receiving data between the gateway unit and the LoRa network server is maintained, so that the gateway can be compatible with the application environment in fig. 1 even if the loraerver unit equivalent to the LoRa network server is integrated in the gateway, can be connected with the LoRa network server in the LoRa network system in fig. 1, and can transmit data, and the gateway is good in flexibility and wide in application range.
Compared with the conventional LoRa network system shown in fig. 1, the gateway in the embodiments of the present application integrates the loraerver unit equivalent to the LoRa network server, so that the deployment of one network element (LoRa network server) is reduced, but the functional structure of the LoRa network system is not changed, and thus the LoRaWan protocol is still followed, and the LoRaWan network system can be interconnected and intercommunicated with other devices following the LoRaWan protocol.
Due to the fact that the LoRa network server is integrated into the gateway, the terminals communicating with the LoRa network server only include the terminals hung down from the gateway, and the number of terminals capable of communicating with the LoRa network server is correspondingly reduced. However, because of the characteristics of wide coverage range (coverage radius can reach more than 15 km) and small data volume of the LoRa wireless network, one gateway can basically meet the coverage of a terminal in a medium-sized park from the performance, and is more suitable for small and medium-sized users sensitive to the engineering price from the perspective of reducing the deployment of the LoRa network server, in conclusion, the LoRa network system shown in fig. 5 is simpler, easier to deploy and flatter.
The various modules in the gateway described above may be implemented in whole or in part by software, hardware, and combinations thereof. The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.
