Base Station Implicit Radio Resource Release Timer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication networks, the inactivity timer for implicit release of common radio resources can lead to incorrect release of resources, resulting in radio link failures and data losses due to misinterpretation of empty buffer status reports.
Innovation Solution
A method where a base station receives an indication of a timer value for implicit release of common radio resources from a radio network controller, allowing it to determine whether to release resources based on this value, thereby avoiding misinterpretations of empty buffer status reports and preventing unnecessary radio link failures.

Engineering Contradiction Analysis
1Productivity
If the inactivity timer is used for implicit release of common radio resources, then resources can be released quickly to be assigned to other users, but the network may incorrectly release resources resulting in radio link failures and data losses
Solution Approach 1:
The patent introduces a feedback mechanism where the base station sends an indication to the UE about the inactivity timer value. This allows the UE to understand when the network intends to release resources, preventing the UE from misinterpreting empty buffer status reports as release signals. The feedback loop ensures both sides have consistent understanding of resource status, eliminating premature releases while maintaining quick resource turnover.
Solution Approach 2:
The patent uses an indication message as an intermediary between the network's resource release decision and the UE's buffer status reporting. This intermediary communication clarifies the network's intent regarding resource release timing, preventing the UE from making incorrect autonomous release decisions. The indication acts as a mediator that synchronizes the understanding between network and UE about resource availability.
2Productivity
If the UE autonomously releases common radio resources after emptying its transmit buffer, then resources are released efficiently, but the network may misinterpret empty buffer status reports leading to incorrect resource release
Solution Approach 1:
The patent establishes feedback from the network to the UE regarding the inactivity timer configuration. This feedback enables the UE to distinguish between buffer emptying events that should trigger resource release versus those that should maintain resource allocation. The UE uses the received timer indication to adjust its autonomous release behavior, preventing misinterpretation of buffer status reports while maintaining efficient resource release when appropriate.
Solution Approach 2:
The patent changes the UE's behavior parameter (resource release decision) based on the received inactivity timer indication parameter. When the UE receives an indication that the network has a short inactivity timer, it adjusts its buffer status reporting and resource maintenance behavior accordingly. This parameter adaptation allows the UE to align its autonomous decisions with network intentions, preventing information loss while maintaining productivity.

AI summary
The proposed technology relates to the issue of supporting release of common radio resources in a radio communication network. A radio network controller sends an indication of a value of a timer for implicit release of common radio resources to a base station. The base station receives the indication of a value of a timer for implicit release of common radio resources and determines whether to release common radio resources based on the indication of a value of the timer for implicit release of common radio resources. In this way, by using the indication of a value of the timer for implicit release the base station will be able to correctly determine whether to release the common resources upon reception of a report of empty buffer status from a UE. This will eliminate misinterpretations of the empty buffer status report, and avoid unnecessary radio link failures.
