Protocol Stack Data Bypass for Communication Device Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, data that does not require processing through mid-stack layers introduces communication delays and increases processing complexity due to conventional routing through all logical layers.
Innovation Solution
A method and apparatus that selectively bypass one or more mid-stack layers of the protocol stack based on the configuration of the radio bearer, allowing data to be routed directly between upper and lower layers when not required to pass through mid-stack layers, thereby reducing delays and processing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is routed through all logical layers of the protocol stack, then complete processing and reliability are ensured, but communication delays increase and processing complexity increases
Solution Approach 1:
The patent implements dynamic routing that adapts the data path based on real-time conditions and data type. The system selectively routes data through different protocol layers depending on whether the data requires full processing (e.g., new data types requiring PDCP layer processing) or can use optimized paths (e.g., established data types bypassing mid-stack layers), thereby resolving the contradiction between complete processing and communication delays
Solution Approach 2:
The patent segments the protocol stack into distinct routing paths: a full processing path through all logical layers (PDCP, RLC, MAC) for data requiring complete handling, and an optimized path that bypasses mid-stack layers for data that doesn't require intermediate processing. This segmentation allows the system to choose the appropriate path based on data characteristics, reducing delays while maintaining reliability when needed
2Reliability
If data is routed through all logical layers of the protocol stack, then complete processing is ensured, but processing complexity increases
Solution Approach 1:
The system dynamically adjusts the processing path based on data type identification. When new data types are detected that require PDCP layer processing, the system activates the full processing path. For established data types, the system uses pre-configured optimized paths that bypass mid-stack layers, thereby reducing processing complexity while maintaining complete processing when necessary
Solution Approach 2:
The patent implements preliminary configuration of optimized routing paths for known data types. The system pre-establishes bypass routes that skip mid-stack layers for data types that have been previously identified as not requiring intermediate processing. This preliminary action reduces the computational burden during runtime by avoiding unnecessary processing steps while maintaining reliability for data types that do require full processing

AI summary
Apparatus, and an associated method, for routing data in a communication device defined in terms of a protocol stack. The protocol stack includes an upper logical layer, a lower logical layer, and a mid stack layer. A determiner determines the configuration of the radio bearer by which the data is to be communicated. If a determination is made that the radio bearer is configured such that it does not require its application to the mid stack layers, a data bypasser causes the data to bypass the mid stack layer. If, conversely, the data is to be applied to the mid stack layer, the data is caused to be routed therethrough.
