Description
Technical field
The present invention relates to wireless communication technology field, the LORA service in wireless communication network packet of a kind of low latency
Transmission method.
Background technology
Internet of Things is the coalition of a kind of sensor network and the Internet, and wherein, sensor network is used for carrying out data acquisition
Collection, man-machine interaction and data short-distance transmission, the Internet is used for carrying out data long-distance transmissions and data, services.Internet of Things
Can be applied to ceaselessly industry, each industry has the data content of self uniqueness, and the various of different industries become Internet of Things certainly
Application system is not sought unity of standard, and forms each information island, it is impossible to carries out efficient data and shares and data exchange, repeats data
Process wastes a large amount of server and energy resources.
Compared with other wireless systems, LORA technology has following several big advantage.It uses spread-spectrum modulation technique, can demodulate
Noise less than 20dB.Which ensure that high sensitivity, reliable network connect, improve network efficiency simultaneously and eliminate dry
Disturb.Compared to mesh network, the star topology of LORAWAN agreement eliminates synchronization overhead and jumping figure, thus reduces merit
Consumption also can allow multiple concurrent application program to run on network.Meanwhile, the communication distance that LORA technology realizes is more wireless than other
Agreement will be much longer so that whole system gets final product work without repeater, thus reduces whole possessing cost.Additionally, phase
Compared with 3G and 4G cellular network, LORA technology extensibility for Embedded Application is higher, and cost performance is higher.
Chinese invention patent application CN 101112057 A discloses one in mobile communication system according to traffic packets
The transmission of control information, including receiving the first message by controlling channel, this first message include with for the of presumptive area
The first point multipoint message traffic group identifier that one group of multiple point multipoint message traffic is relevant.The method also includes being connect by control channel
Receiving the second message, this second message includes that the first point multipoint message traffic group identifier list includes at least that subscriber equipment is predetermined
Individual business, the method also includes that the control information according to receiving by controlling channel processes.
Summary of the invention
The technical issues that need to address of the present invention are the LORA service in wireless communication network packet transmission sides of a kind of low latency
Method.
For solving above-mentioned technical problem, the LORA service in wireless communication network packet transmission of a kind of low latency of the present invention
Method, comprises the following steps,
Step S101: node region divides, and according to its affiliated area, nodes is carried out region division, a region
Including a LORA gateway and some LORA nodes；
Step S102: traffic packets, by the distribution of services that belongs in same node region to affiliated node region
On LORA gateway；
Step S103: business subdividing transmission, Packet Service is distributed to phase by LORA gateway in affiliated node region respectively
On the LORA node closed.
Further, in described step S103 business subdividing transmission, Packet Service is in parallel distributed to relevant by LORA gateway
On LORA node.
Further, area flag position, described district are added described in described step S102 traffic packets after business datum
Territory flag bit is corresponding with the node region of the division in step S101.
Further, in described step S103 business subdividing transmission, LORA gateway LORA joint in affiliated node region
Point sends Packet Service, and LORA node is receiveed the response uploading after receiving Packet Service；LORA gateway receives LORA node and returns
Confirm after answering information that Packet Service has been distributed.
Further, in described step S103 business subdividing transmission, described LORA gateway is in affiliated node region
LORA node adds check bit after sending grouping busihess data, and LORA node is just verifying check bit after receiving Packet Service
Really property, then uploads and receives the response.
After using said method, the LORA service in wireless communication network block transmission method of a kind of low latency of the present invention passes through
Arrange node region to divide in corresponding distribution of services to corresponding node region directly, reduce the delay of traffic packets,
Save the time of distribution of services；It addition, by arranging increase check bit in distribution service information, verify whether to distribute successfully,
Improve the accuracy of distribution of services.
Accompanying drawing explanation
