Terminal Coverage Class Reporting for Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in IoT environments, there is no dedicated procedure for reporting coverage class changes by terminals in disconnected states, leading to communication limitations and resource wastage due to inconsistencies in coverage class information between terminals and network devices.
Innovation Solution
The terminal actively measures and reports its current coverage class to the network, allowing the network to update its records, thereby avoiding communication limitations and resource wastage by ensuring accurate resource allocation and efficient use of network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the terminal does not report coverage class information in disconnected state, then the terminal can save signaling overhead and energy consumption, but the network cannot obtain accurate coverage class information leading to communication limitations and resource allocation inefficiency
Solution Approach 1:
The terminal performs coverage class measurement and sends measurement results to the network device before actual data transmission occurs. This preliminary action ensures the network has accurate coverage class information ready when needed, avoiding communication limitations while the terminal remains in disconnected state.
Solution Approach 2:
The terminal actively measures and feeds back coverage class information to the network device. This feedback mechanism ensures the network maintains accurate coverage class information for the terminal even when disconnected, enabling reliable resource allocation and communication.
2Productivity
If the terminal actively reports coverage class information, then the network can allocate resources accurately and improve communication efficiency, but the terminal increases signaling overhead and network processing load
Solution Approach 1:
The patent extracts only the essential coverage class measurement information from the terminal and sends it to the network device, rather than transmitting all possible terminal parameters. This selective extraction reduces signaling overhead while maintaining the necessary information for accurate resource allocation.
Solution Approach 2:
The coverage class measurement and reporting is performed in advance when the terminal is in disconnected state, rather than during active communication. This preliminary action prevents increase in signaling overhead during data transmission, as the information is exchanged beforehand.
3Device complexity
If the network uses outdated coverage class information, then the network can maintain simpler information management, but the terminal experiences communication limitations and resource allocation inefficiency
Solution Approach 1:
The terminal provides feedback to the network device about its current coverage class through measurement reports. This feedback mechanism ensures the network maintains up-to-date coverage class information without increasing information management complexity, as the terminal autonomously generates and sends the updates.
Solution Approach 2:
The terminal autonomously measures its own coverage class and generates measurement reports without requiring network intervention. This self-service approach allows the network to maintain accurate information with minimal processing effort, as the terminal independently manages its own coverage class reporting.

AI summary
The present invention provides an information transmission method, including: obtaining, by a terminal in a disconnected state, information about a current coverage class of the terminal; and sending, by the terminal, a first message to an access network device, where the first message carries information about a coverage class of the terminal. The terminal in the disconnected state actively reports the information about the coverage class, so that a network device learns of the information about the coverage class of the terminal in a timely manner. In this way, during communication, a communication limitation or communication resource waste caused by inconsistency between information about a coverage class of the terminal that is stored on a network side and information about an actual coverage class can be avoided, and network resources can be fully used.
