User Equipment Buffer Check for LTE Resource Request Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE communication systems, user equipment (UE) experiences significant time delays and resource wastage due to repeated scheduling requests and random access attempts for air interface resources, leading to inefficiencies in resource allocation and increased signaling overhead.
Innovation Solution
Implementing a method in user equipment to detect whether buffered data is still stored before initiating resource requests, allowing the UE to determine whether to continue or terminate the resource requesting process with the base station, thereby avoiding requests for invalid data and optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continues to send scheduling requests and random access attempts multiple times to request air interface resources, then the UE can obtain resources for sending uplink data, but the time delay increases significantly and may exceed the service time requirement
Solution Approach 1:
The UE checks whether buffered data still exists before each scheduling request or random access attempt. This preliminary check prevents initiating resource request procedures when data has already been discarded, thereby avoiding unnecessary time delays while ensuring resource allocation only occurs when actually needed
2Reliability
If the UE sends multiple scheduling requests and random access attempts to request air interface resources, then the resource allocation can be achieved, but air interface resources are wasted and signaling overhead increases
Solution Approach 1:
The UE continuously monitors the buffer status and provides feedback to the resource request process by checking data availability before each scheduling request or random access attempt. This feedback mechanism ensures that resource requests are only sent when buffered data actually exists, preventing waste of air interface resources and reducing signaling overhead

AI summary
The present invention provides a method for processing a resource request, a user equipment and a communication system. The method for processing the resource request includes: detecting whether buffered data is stored in the buffer; and determining, according to the result of the detecting, whether to start or to continue a resource requesting process with a base station, where the resource requesting process is used for requesting the base station to allocate the resource for sending the buffered data stored in the buffer; where the resource requesting process is a scheduling request process or a random access process. By adopting the technical solutions in the embodiments of the present invention, it can be effectively avoided that a user equipment requests an air interface resource for the buffered data that has already been invalid in the buffer, thereby the air interface resource can be effectively saved and the overhead of air interface signaling can be saved as much as possible.
