Preconfigured Resource Release in LTE MTC Idle State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE MTC, preconfigured resources allocated to user equipment (UE) are often wasted when they are not properly released, especially in scenarios where data transmission is periodic and resources are not used for extended periods or in cases of network overload.
Innovation Solution
A method and apparatus that enable user equipment (UE) to receive configuration information for preconfigured resources and determine based on indication information whether these resources are valid or need to be released, ensuring timely recycling and reallocation of resources, particularly by using validity periods or usage counts to assess resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If preconfigured resources are allocated to UE for data transmission in idle state, then data transmission efficiency is improved, but resource wastage occurs when resources are not properly released
Solution Approach 1:
The base station monitors the usage status of preconfigured resources and sends indication information to the UE when resources should be released. This feedback mechanism ensures that resources are properly released when no longer needed, preventing resource wastage while maintaining transmission efficiency during active use
Solution Approach 2:
The patent introduces a validity period parameter for preconfigured resources. The resource configuration includes a validity period indicator that defines how long the preconfigured resource remains valid. When the validity period expires or usage conditions are met, the resource is automatically released, dynamically managing resource allocation to balance efficiency and wastage
2Productivity
If preconfigured resources are allocated to UE, then resource utilization is improved, but network overload may occur when resources are not released timely
Solution Approach 1:
The base station actively monitors resource usage and sends release indication information to UE when resources should be freed. This feedback loop prevents resource accumulation that could lead to network overload while maintaining high resource utilization during periods of active data transmission
Solution Approach 2:
The patent implements periodic resource validation through validity period indicators. Preconfigured resources are allocated for specific durations and automatically released when the period expires, creating a rhythmic pattern of allocation and release that prevents continuous resource holding and potential network overload
3Productivity
If preconfigured resources are allocated for periodic data transmission, then transmission efficiency is improved, but resources remain idle for extended periods
Solution Approach 1:
The patent introduces validity period parameters that define the active window for preconfigured resources. Resources are allocated with specific validity periods matching the periodic transmission requirements, and automatically released when periods expire or usage conditions are met, minimizing idle time while maintaining transmission efficiency during active periods

AI summary
A resource configuration method and an apparatus are applied to the field of communications technologies. The method includes: a user equipment (UE) receives a first message sent by a base station. The first message carries configuration information of a preconfigured resource, and the preconfigured resource is used for data transmission by the UE in an idle state. The UE obtains first indication information, and releases the preconfigured resource based on the first indication information.
