LTE Short Data Burst Indicator for RRC Connection Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LTE networks are inefficient in managing resources for short data burst communications due to the need for establishing, configuring, and releasing complete radio resource connections, which consumes bandwidth and processing resources even when only small amounts of data are exchanged.
Innovation Solution
A method and system that optimize LTE network capacity by using a mobile originated SDB indicator to manage RRC connections efficiently, allowing for the release of resources without completing call admission control messages and optimizing capacity by determining if the amount of data to be transmitted exceeds a threshold, thereby reducing unnecessary resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complete RRC connection is established, configured, and released for SDB communications, then service quality is maintained, but network resource efficiency deteriorates due to excessive bandwidth and processing consumption
Solution Approach 1:
The patent segments the RRC connection management into two distinct paths: a complete connection path for large data transmissions and a simplified path for short data bursts. By introducing the SDB indicator, the system divides the handling of different data types, allowing SDB communications to use a streamlined process that skips full connection configuration while maintaining reliability for actual data delivery.
Solution Approach 2:
The patent applies partial action by performing only the necessary minimum steps for SDB communications. Instead of completing the full RRC connection setup, configuration, and release sequence, the system executes a reduced set of actions triggered by the SDB indicator, thereby consuming fewer network resources while still achieving the communication objective.
2Loss of time
If RRC connections are maintained (not released) to avoid setup overhead, then connection establishment efficiency is improved, but network resource utilization deteriorates due to dedicated bandwidth and processing for idle connections
Solution Approach 1:
The patent introduces dynamic RRC connection management where the connection state is flexibly adjusted based on the SDB indicator. When SDB is detected, the system transitions to a simplified handling mode that releases connections promptly after data transfer. This dynamic approach allows the network to adapt connection lifecycle to actual needs, preventing both excessive setup overhead and resource waste from prolonged connection maintenance.
Solution Approach 2:
The patent changes the operational parameters of RRC connections based on data type. By introducing the SDB indicator as a new parameter, the system modifies connection behavior: for SDB, connections are established minimally and released quickly; for other data types, full connection management is applied. This parameter-driven approach optimizes the balance between connection establishment speed and resource utilization.
3Productivity
If the SDB indicator and optimized message flow are implemented, then network capacity efficiency is improved, but system complexity increases due to additional indicators and message modifications
Solution Approach 1:
The patent makes the SDB indicator a universal element that can be embedded in multiple existing message types (RRC connection request, RRC connection setup complete, initial UE message). This multi-functional approach allows a single indicator mechanism to trigger optimized handling across different stages of the communication process, improving network capacity efficiency without requiring entirely new message structures for each stage.
