Further, southbound interface module, which carries out protocol conversion to terminal data message, can be former base in LoRaWan
The terminal data message of agreement is converted to the terminal data message based on ieee802.3 agreement.
Wherein the transport layer of the terminal data message of ieee802.3 agreement follows UDP (User Datagram
Protocol, User Datagram Protocol) agreement, application layer using JSON (JavaScript Object Notation,
JavaScript object numbered musical notation) agreement.
Further, southbound interface module responds the 2nd ACK report to terminal forwarding module when obtaining networking request plaintext
Text.
Specifically, the group packet protocol of networking request message MAC layer follows LoRaWan agreement, transport layer uses udp protocol,
Application layer uses JSON agreement；
It include tri- parameters of AppEUI, DevEUI and DevNonce in networking request message, wherein AppEUI is for identifying
It uniquely applies supplier, such as the dustbin of each family to monitor application, smoke alarm application etc., all has unique
AppEUI, for the parameter being arranged in the terminal in advance；DevEUI can be the MAC Address of terminal for identifying unique terminal；
DevNonce is the RSSI random value of LoRa chip in terminal；
LoRaWan protocol stack module is according to the terminal address that the DevEUI in networking request message is distributed
The NetID generated when DevAddr, DevAddr are together with AppNonce and distribution forms networking response message, and wherein AppNonce is
It is randomly generated, the effect of NetID is similar to subnet mask；
After terminal 102 receives networking response cyphertext, extract DevAddr therein, and combine AppKey, AppNonce,
NetID and DevNonce, is encrypted using aes128, generates 2 keys: NekSKey and AppSKey, and terminal 102, which networks, to be completed.
Wherein NekSKey is used for the encryption and decryption of terminal management message, and AppSKey is used for the encryption and decryption of terminal data message；AppKey by

Configuration Protocol (server) daemon), dynamic host configuration protocol finger daemon) algorithm, in addition to being used for
Realize that the terminal address above-mentioned distributed according to DevEUI is DevAddr, additionally it is possible to which the MAC Address that gateway is arranged is old
Change the time, the terminal address that distribution can be made to obtain is not overlapped, and is realized by the MAC address aging time and handed over for a long time without message
Mechanism is withdrawn in the address changed, and avoids occupying DevAddr when terminal 102 is not online for a long time after networking.
It should be further noted that since the transport layer for managing message that application server 106 issues is assisted using UDP
View, application layer uses JSON agreement, and LoRaWan agreement provides that LoRa network server is sent to the management message of gateway and abides by
GWMP (LoRa Gateway Message Protocol, LoRa gateway message protocol) agreement is followed, so LoRaWan protocol stack
Module needs to parse management message, and concrete processing procedure includes: that the first JSON load is parsed from terminal management message
Lotus obtains terminal management analytic message as terminal management data, based on terminal management data；When southbound interface module receives
When pull message, using terminal management analytic message as PULL_RESP message, LoRaWan protocol stack mould is by PULL_RESP message
It is transferred to southbound interface module；Wherein, PULL_RESP message length must not exceed 1000 eight bit bytes.Concrete processing procedure
Further include: the 2nd JSON load is parsed from gateway management message, obtains gateway configuration-direct.
The southbound interface module referred in above-mentioned gateway receives the periodical pull message of terminal forwarding module transmission, practical
On be equal in traditional LoRa network system as shown in Figure 1 gateway to LoRa network server sending cycle pull message
(periodical pull message for keep it turned on the firewall of LoRa network server), and combine default port and
Loopback interface can independently be arranged and southbound interface module to terminal forwarding module respond the 2nd ACK message.Actually protect
The function of sending and receiving data between gateway unit and LoRa network server is stayed, even if so that above-mentioned gateway has been internally integrated equally
In the LoRaServer unit of LoRa network server, the application environment that can be also compatible in Fig. 1 can be with the LoRa network of Fig. 1
LoRa network server in system connects and sends data, and flexibility is good, applied widely.
Compare traditional LoRa network system as shown in Figure 1, since the gateway in each embodiment of the application is integrated with
It is same as the LoRaServer unit of LoRa network server, and then reduces the deployment of a network element (LoRa network server),
But the functional structure without changing LoRa network system can follow to still follow LoRaWan agreement with other
The device interoperability of LoRaWan agreement.
Since LoRa network server is integrated into the reason of gateway, cause the terminal communicated with LoRa network server can be only
The quantity of terminal comprising gateway down-hanging, the terminal that can be communicated to LoRa network server corresponding can be reduced.But due to LoRa
The small feature of wireless network coverage wide (covering radius is up to 15 kilometers or more), data volume, gateway base from performance
Originally the covering to terminal in a median size garden, and the angle of the deployment from reduction LoRa network server be can satisfy
Degree, is more suitable for the middle-size and small-size user sensitive to engineering price, and to sum up, LoRa network system as shown in Figure 5 is simpler, more
It is easy deployment, more flattening.
