UE Compression Buffer Control for Dynamic UDC Dictionary Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio technology systems face challenges in dynamically configuring an appropriate dictionary for User Equipment (UE) during data transmission, leading to inflexible data compression and decompression processes.
Innovation Solution
A buffer control method and UE design that allow the network side device to dynamically configure and notify the UE about dictionary activation, deactivation, or resetting for Uplink Data Compression (UDC), enabling the UE to perform UDC using dynamically configured dictionaries rather than pre-stored static dictionaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-stored static dictionaries are used in UE, then data compression can be performed, but the system lacks flexibility in adapting to different transmission conditions and data types
Solution Approach 1:
The patent implements dynamic dictionary configuration where the network side device can activate, deactivate, or reset dictionaries in the UE's compression buffer through control messages. This allows the system to adapt to different transmission conditions and data types by dynamically selecting appropriate dictionaries, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The patent introduces a feedback mechanism where the UE reports buffer status and compression performance to the network side device, which then makes informed decisions about dictionary configuration. This feedback loop enables adaptive optimization of compression performance while maintaining manageable system complexity through centralized control.
2Productivity
If dynamic dictionary configuration is implemented, then data transmission efficiency improves, but buffer management complexity increases
Solution Approach 1:
The network side device acts as an intermediary that manages dictionary configuration for multiple UEs. By centralizing the decision-making process for dictionary activation, deactivation, and resetting at the network side, the patent improves overall system productivity while preventing excessive complexity from propagating to individual UE devices.
Solution Approach 2:
The UE autonomously manages its compression buffer by automatically updating it with uncompressed data packets and selecting appropriate dictionaries based on network side device instructions. This self-service approach allows efficient buffer management at the UE level without requiring complex centralized control for every operation.
Data Source
AI summary
A buffer control method, a UE, and a non-volatile computer-readable storage medium are provided. The buffer control method for the UE includes: transmitting, by the UE, first check information to a network side device; receiving, by the UE, first buffer resetting information from the network side device; releasing or emptying a current compression buffer of the UE in accordance with content in the first buffer resetting information; and when the UE receives a dictionary activating or enabling indication: storing, by the UE, a dictionary into the compression buffer; compressing, by the UE through UDC, an uncompressed data packet to obtain a compressed data packet; and transmitting, by the UE, the compressed data packet, wherein the compression buffer is continuously updated by the UE in accordance with the uncompressed data packet.
