Problems solved by technology

[0002] In the standard LoraWAN protocol, after a terminal device sends a network access request, the server directly replies with an ACK for network access. Since Lora works in half-duplex mode, it cannot accept the uplink of the terminal when the gateway is downlink. Therefore, if a large number of terminals simultaneously When requesting network access, the gateway will respond to a terminal’s network access, and other terminals also request network access on this channel, resulting in a low success rate of network access and a long time to access the network

Embodiment 1

[0044] refer to figure 1 , the network access method of this embodiment is applicable to the LoRa communication network and is suitable for execution by a network access device. The network access device refers to a device that requests network access, which may be a terminal, a repeater or a router.

[0045] The method of this embodiment includes:

[0046] S101. The network access device monitors the downlink channel of the network access response device, and infers the downlink cycle / downlink time point of the network access response device according to the monitored data packets;

[0047] The network access response device refers to the device responsible for responding to the network access device requesting network access, and the network access response device may be a gateway, a repeater or a router.

[0048] The number of data packets sent by the network access response device in the present invention is fixed in the downlink cycle, and when there is not a sufficient ...

Embodiment 2

[0062] refer to figure 2 , the network access method of this embodiment is applicable to the LoRa communication network and is suitable for execution by a network access response device. The network access response device refers to a device responsible for responding to a network access device requesting network access. The network access response device may be a gateway, a repeater or router.

[0063] The method of this embodiment includes:

[0064] S201. The network access responding device monitors the network access channel in an uplink period to receive network access packets and caches network access requests of all network access devices.

[0065] Sending a network access packet by a network access device is equivalent to sending a network access request. A network access device refers to a device requesting network access, which may be a terminal, a repeater, or a router.

[0066] S202. The network access responding device processes the network access requests in t...

Embodiment 3

[0073] refer to image 3 , the network access device of this embodiment is applicable to the network access device of the LoRa communication network, and the network access device refers to a device that requests network access, which may be a terminal, a repeater or a router.

[0074] The network access equipment of this embodiment includes:

[0075] Downlink period / downlink time point estimation module 301, configured to monitor the downlink channel of the network access response device, and estimate the downlink period / downlink time point of the network access response device according to the monitored data packets, wherein: the network access response device has no When a sufficient number of data packets need to be sent, use idle packets instead of data packets to ensure that the number of data packets sent in each downlink cycle is fixed;

[0076] The network access request module 302 is used to send the network access packet to the network access channel during the non...

Abstract

The invention discloses a network access method, network access equipment, network access response equipment and a readable storage medium, and the method comprises the steps that the network access equipment monitors a downlink channel of the network access response equipment, and presumes the downlink period / downlink time point of the network access response equipment according to a monitored data packet; the network access equipment sends a network access packet to the network access channel at a non-downlink period / non-downlink time point, so that the network access response equipment receives the network access packet, caches network access requests of all the network access devices, performs packet processing on the network access requests in the cache in a downlink period, and sendsa network access confirmation packet to the network access devices in the same group at the same time in a multicast mode; and the network access equipment is switched to the receiving mode to wait for receiving the network access confirmation packet which is multicast by the network access response equipment and contains the information of the network access equipment. According to the invention, the network access efficiency can be greatly improved.
