LoRaWAN Terminal Network Access via Dynamic Channel Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent channel use plans between terminals and base stations in LoRaWAN networks lead to incompatibility issues, preventing terminals from connecting to base stations.
Innovation Solution
A method where terminals send a request message via a first channel to access the network, receive channel plan information from a base station via a second channel, and determine a network connection plan to access the network through a second base station, using a channel mask to map a channel subset for successful connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different manufacturers adopt different channel use plans for connecting terminals and base stations, then each manufacturer can optimize for its own devices, but compatibility and connection success between terminals and base stations deteriorate
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting channel parameters based on the determined network connection plan. The terminal receives channel plan information from the base station, determines an appropriate network connection plan, and then changes its channel parameters accordingly to match the base station's configuration, ensuring compatibility while allowing manufacturer-specific optimizations
Solution Approach 2:
The patent implements dynamics by making the channel use plan adaptive rather than static. The terminal dynamically determines the network connection plan based on received channel plan information and selects appropriate channels from the channel set, allowing the system to adapt to different manufacturer configurations and ensure successful connections
2Reliability
If a terminal sequentially sends messages via multiple channels within a channel set, then the probability of successful connection improves, but the time required for network access increases
Solution Approach 1:
The patent applies preliminary action by having the terminal receive channel plan information from the base station before attempting network access. This allows the terminal to pre-determine the appropriate network connection plan and select the correct channels in advance, avoiding the need to sequentially try multiple channels and reducing access time while maintaining connection success rate
Solution Approach 2:
The patent implements feedback by having the base station provide channel plan information to the terminal in response to the terminal's access request. This feedback mechanism allows the terminal to adjust its channel selection based on the base station's configuration, enabling direct connection without sequential channel probing

AI summary
The present disclosure provides a terminal, a base station and methods for communications between the terminal and the base station, and for the terminal to access a network. According to one exemplary method, a terminal sends a first message to a base station via a first channel, the first message being used to request access to a network. The terminal receives a second message from a first base station via a second channel, the second message including channel plan information for determining a first network connection plan. The terminal determines the first network connection plan according to the channel plan information and accesses the network via a second base station according to the first network connection plan. Channel use plan of the base station can be obtained through signaling interactions in the process of network connection. The terminal can determine whether the network can be accessed and access the network accordingly.
