At present, The network access modes of LoRaWAN comprise two modes, namely OTAA (OveW-The-AirA Activation in The air) and ABP (Activation By Personalization independent Activation). The OTAA configures the same triple information (DevEUI (device unique identification code), AppEUI (application identification code), and AppKEY) in advance for the device side and the server side, the device sends a networking request, the server receives the triple information and verifies the triple information, and after verification is successful, the device and the server obtain the same DevAddr (short address), NwkSKey, and AppSKey (application session key). The ABP configures the same session address and key information DevAddr (short address), NwkSKey (network session key), and AppSKey (application session key) for the device side and the server, and does not need to perform a networking process.
The ABP mode is configured with session key information and the like, the key is transmitted to the equipment end and the network server in a plaintext mode for adding, and once the information reveals communication data, the information can be monitored and decrypted. The network access mode of the OTAA is that only DevEUI (device unique identification code), AppEUI (application identification) and AppKEY (application key) are configured at the device end and the server end, information such as the key dynamically generated during network access is adopted during data communication, and different parameters such as session information are dynamically allocated during network access every time, so that preconfigured information is leaked, communication data cannot be decrypted, and the security of the data is higher, so that the OTAA is also the mainstream network access mode at present.
The network access mode of OTAA needs to count the information of each device before deployment, and the information is manually entered into a network server after counting, so that huge manpower and material resources are needed under the condition of a large number of deployed devices, and phenomena such as mismatching and omission easily occur. In the maintenance process, equipment damage, replacement and newly added equipment are inevitable, and independent statistics and entry to a network server are required each time, so that the workload and difficulty of deployment and maintenance are greatly increased.

The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
the first embodiment is as follows:
referring to fig. 1 and fig. 2, a terminal network access method of a LoRaWAN server according to a first embodiment of the present invention is provided. The terminal network access method is described from the server side, and may be executed by a LoRaWAN server (hereinafter referred to as a server). In particular, for execution by one or more processors within a server, to implement the steps of:
and S102, receiving a networking request packet sent by the terminal. The networking request packet comprises a device unique code, an application identifier and an application key of the terminal.
In this embodiment, the terminal may be a networking device in the internet of things, for example: temperature and humidity sensor terminals, water meters, gas meters, smoke alarms, pet trackers, and the like, which are not particularly limited in this respect.
It is understood that the networking request packet may include other information, such as a data packet header, a check code, a random number, etc., in addition to a device unique code (DevEUI), an application identifier (AppEUI), and an application key (AppKEY) of the terminal. The specific content of the request packet for networking belongs to the prior art, and the detailed description of the present invention is omitted.
It should be noted that the network access mode of the LoRaWAN protocol includes an open intermediate activation (OTAA) and an independent Activation (ABP). In the independent activation mode, the server directly establishes connection with the terminal after receiving the networking request without verification, and in the air activation mode, after receiving the networking request packet, the server needs to check whether the terminal is recorded into a database of the server according to the content of the networking request packet, and only the terminal recorded into the database can establish connection with the server. The invention aims at optimizing an air activation network access mode.
In the prior art, network access is performed by using an over-the-air activation method, and triple information of a terminal, namely, three information, namely, a device unique code (DevEUI), an application identifier (AppEUI), and an application key (AppKEY), needs to be recorded in advance on a server. Whether to establish connection with the terminal is determined by checking whether the triplet information of the terminal exists on the server.
As shown in fig. 2, a networking request packet sent by a terminal may be transmitted to a server only through an intermediate device such as a gateway, which belongs to the prior art and is not described in detail herein.
S103, judging whether the terminal belongs to the existing group or not according to the application identifier and the application key. Where each packet has a different application identity and application key.
It should be noted that the triplet information of the terminal is preset by the manufacturer when the terminal is produced or shipped from the factory. Different terminals may have the same application identification and application key, but the device unique code is unique.
In this embodiment, when setting triplet information, terminals are grouped according to the type of the terminal or an application scenario, and terminals grouped by each terminal set the same application identifier and application key. Also, groups are provided on the servers, each server group having different grouping parameters. The packet parameters are the application identification and the application key of the packet. The grouping on the server may be preset by a manufacturer when the server leaves a factory, or may be set by a user, which is not specifically limited by the present invention.
In other embodiments, the application identifier and application key of each terminal may also be set to be unique. I.e. only one terminal per packet on the server. Before a new terminal is added, a new group needs to be created on the server, and an application identifier and an application key of the terminal are input.
A terminal belongs to a group of servers when its application identity and application key are the same as those of the group. I.e. belonging to an existing packet on the server.
On the basis of the foregoing embodiment, in an optional embodiment of the present invention, step S103 specifically includes:
and searching the existing group according to the application identifier and the application key of the terminal.
And when the application identifier and the application key of the existing group are the same as the application identifier and the application key of the terminal, judging that the terminal belongs to the existing group. Otherwise, judging that the terminal does not belong to the existing group.
Specifically, after receiving a networking request packet sent by a terminal, the server analyzes the packet according to the LoRaWAN protocol, and sequentially checks whether an application identifier and an application key in the networking request packet are the same as packet parameters in the network server.
And S104, when the terminal is judged to belong to the existing group, establishing connection with the terminal according to the unique equipment code. Otherwise, the network request packet is discarded.
In this embodiment, when it is determined that a packet parameter consistent with a parameter in a request packet for network addition exists, that is, when it is determined that a terminal belongs to an existing packet, verification is passed and subsequent steps are executed, and the subsequent steps are not used as a basis for determining whether to establish a connection. Therefore, in the previous entry work, only the application identifier and the application secret key need to be entered into the server, and the unique code of the equipment does not need to be entered, so that the labor amount of workers is greatly reduced, and the method has good practical significance.
On the basis of the foregoing embodiment, in an optional embodiment of the present invention, step S104 specifically includes:
and when judging that the terminal belongs to the existing group, inquiring whether the unique equipment code exists in the database.
And when the unique equipment code exists in the database, establishing connection with the terminal.
And when the unique equipment code does not exist in the database, recording the unique equipment code into the database and then establishing connection with the terminal.
In this embodiment, after the application id and the application key are verified. And when the terminal is judged to belong to the existing group, further checking the unique code of the equipment. But directly looks up whether the device unique code of the terminal exists in the database. When the code exists, the information such as the session key is updated and connection is established with the terminal. And when the code does not exist, recording the unique code of the equipment in the networking request packet into a guide database, then updating information such as a session key and the like, and establishing connection with the terminal.
Therefore, the server can be connected without inputting the equipment one-bit code of the terminal on the server in the earlier stage, so that the work of inputting information into the server in the earlier stage work is greatly reduced, and the risk of information leakage in the earlier stage information handover work is also reduced. And because a plurality of terminals correspond to one group, the information amount which needs to be input into the server in the earlier stage is greatly reduced.
Specifically, after the unique equipment code is inquired to exist in the database or the unique equipment code is recorded into the database, a networking acceptance packet is added according to a LoRaWAN protocol group, the networking acceptance packet is forwarded to the equipment through a gateway, and finally, the equipment is kept consistent with the DevAddr (short address), the NwkSKey (network session key) and the AppSKey (application session key) of the network server according to the LoRaWAN protocol and an encryption and decryption algorithm. Subsequent data communications are communicated using these parameters. Which belongs to the prior art, the present invention is not described again.
The terminal network access method of the LoRaWAN server only improves the server, can reduce the workload of workers and the risk of information leakage on the premise of not changing the original network access mode of air activation, and has good practical significance.
As shown in fig. 3, on the basis of the foregoing embodiment, in an alternative embodiment of the present invention, step S102 further includes:
s101, creating a grouping. Wherein the packet is configured with an application identity and an application key.
In this embodiment, a new group may be created on the server (i.e., a new application identifier and a new application key are entered), so that the server may connect to the terminal of the new group. The expansion capability of the server is ensured.
