Sporadic Data Transmission Control in Telecommunication Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed packet access technologies, such as UMTS, face inefficiencies in power consumption and interference due to sporadic data transmissions, particularly in applications with periodic data, like VoIP and client-server sessions, where unnecessary DPCCH transmissions occur, increasing interference and power usage.
Innovation Solution
A telecommunication apparatus and method that determines if omitting sporadic data transmissions, such as Silence Insertion Descriptor (SID) frames, will significantly degrade performance, and if not, disables these transmissions to reduce unnecessary DPCCH activity, allowing the system to operate in a further reduced mode with lower power consumption and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sporadic data transmissions (SID frames) are sent periodically to maintain background noise, then communication quality is maintained, but power consumption and interference increase
Solution Approach 1:
The patent applies partial action by selectively transmitting only certain SID frames (e.g., first and second SID frames of a silent period) while omitting others. This partial transmission approach maintains acceptable background noise for communication quality while reducing power consumption compared to continuous SID frame transmission.
2Reliability
If DPCCH transmissions are sent in each slot (normal activity mode), then communication reliability is maintained, but interference and power consumption increase
Solution Approach 1:
The patent implements periodic action by gating DPCCH transmissions to occur only in specific slots according to a determined pattern, rather than continuously in every slot. This periodic transmission reduces interference while maintaining communication reliability through selective transmission at critical moments.
3Use of energy by moving object
If DPCCH transmissions are reduced to further reduced mode, then power consumption and interference are reduced, but performance may be significantly degraded
Solution Approach 1:
The patent employs feedback by continuously monitoring communication conditions and performance metrics to dynamically adjust the transmission pattern. This feedback mechanism ensures that further reduced mode operation does not significantly degrade performance, as the system adapts to maintain acceptable communication quality while saving power.
Solution Approach 2:
The patent applies dynamics by making the transmission pattern adaptive and flexible rather than fixed. The gating pattern can be dynamically adjusted based on current communication needs, allowing the system to transition between different transmission intensities as conditions change, thus maintaining performance while optimizing power consumption.
