Radio Access Node CE Authorization for IoT Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Internet of Things (IoT) applications, the conventional coverage enhancement (CE) function implementation based solely on radio channel quality leads to inefficient use of radio channel resources, especially in scenarios with a large number of terminals and limited bandwidth, as all terminals are allowed to use CE without authorization, resulting in suboptimal resource allocation.
Innovation Solution
A method and device where a first radio access network node obtains CE authorization information for a terminal, determining if the terminal's CE level meets authorization requirements, and controls the use of the CE function accordingly, ensuring only authorized terminals use the CE function within an authorized range, thereby improving radio channel resource use efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal uses the CE function based on only radio channel quality, then coverage enhancement is achieved, but radio channel resource use efficiency deteriorates
Solution Approach 1:
The patent changes the control parameter from solely radio channel quality to a combination of radio channel quality and authorization status. The network configures authorization information (CE authorization indication, authorized CE level range) that restricts which terminals can use CE function and at what levels, thereby improving resource efficiency while maintaining coverage enhancement for authorized terminals
Solution Approach 2:
The patent introduces an authorization mechanism as an intermediary between the terminal and the CE function. The network acts as a mediator that evaluates both radio channel quality and authorization status before allowing CE function usage, preventing unauthorized terminals from consuming radio resources while still providing coverage enhancement where appropriate
2Reliability
If all terminals are allowed to use CE function, then coverage is improved, but radio channel resource allocation deteriorates
Solution Approach 1:
The patent applies local quality by differentiating treatment for different terminals based on their authorization status and radio channel conditions. Authorized terminals in poor coverage areas receive CE function with appropriate CE levels, while unauthorized or well-covered terminals do not use CE resources, creating localized optimized resource allocation rather than uniform allocation

AI summary
Embodiments of the present application provide a coverage enhancement (CE) function implementation method and a device. The method may include obtaining, by a first radio access network node, CE authorization information of a terminal. The CE authorization information may include at least one of the following: CE indication information and an authorized CE level range. Further, the method may include determining, by the first radio access network node based on the CE authorization information, whether a CE level of the terminal meets an authorization requirement, and controlling, based on an authorization result, use of a CE function by the terminal. It can be learned that, not all terminals can use the CE function, but only an authorized terminal can use the CE function, to ensure that the terminal can use the CE function properly within an authorized range and to improve radio channel resource use efficiency.
