Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as GSM/GPRS, fail to adapt to the requirements of delay-sensitive applications like real-time and streaming applications, leading to performance degradation due to operational delays caused by multiple resource allocation and release cycles.
Innovation Solution
A mobile station with an uplink resource release controller that selectively inhibits resource release based on parameters like data transfer rates, historical delay data, and buffer states to prevent initiation of the countdown process, using techniques such as writing dummy blocks to the data buffer to maintain continuous data flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the countdown process is initiated to release uplink resources efficiently, then resource sharing efficiency is improved, but transmission delays increase for delay-sensitive applications
Solution Approach 1:
The patent applies dynamics by making the resource release decision adaptive rather than fixed. The controller dynamically adjusts the countdown process based on real-time parameters including data buffer state, transmission rate, and application requirements. This allows the system to maintain efficient resource sharing while preventing premature release that would cause transmission delays for delay-sensitive applications.
Solution Approach 2:
The patent implements feedback mechanisms where the controller continuously monitors parameters such as data buffer occupancy, transmission rate, and application performance. This feedback information is used to adjust the countdown process and resource release timing, ensuring that resources are released at the optimal moment that balances efficiency with maintaining acceptable transmission delays.
2Adaptability or versatility
If multiple resource allocation/release cycles are performed, then resource allocation flexibility is improved, but operational delays increase substantially
Solution Approach 1:
The patent applies preliminary action by preparing and buffering data in advance during periods of low demand. The controller proactively manages the data buffer to ensure sufficient data is ready for transmission when resources are allocated, reducing the need for multiple allocation/release cycles and minimizing operational delays.
Solution Approach 2:
The patent utilizes parameter changes by adjusting key parameters such as data buffer size, countdown threshold values, and resource allocation timing based on current system conditions. This allows the system to maintain allocation flexibility while reducing the frequency and duration of resource allocation/release cycles, thereby minimizing operational delays.
3Productivity
If uplink resources are released promptly, then resource availability for other users is improved, but data transmission continuity deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-buffering data and preparing transmission packets before resource release is triggered. This ensures that when resources are released and reallocated, the data is already prepared for immediate transmission, maintaining continuity and reducing interruptions in audio or video streams.
Solution Approach 2:
The patent implements beforehand cushioning by maintaining a cushion of data in the buffer and keeping the countdown process flexible. This cushioning approach ensures that even if resources are released and reallocated, there is sufficient data ready to maintain transmission continuity, thereby cushioning against interruptions while still allowing resource availability for other users.

AI summary
A mobile station for transferring delay-sensitive data to a wireless communications network is provided with an uplink resource release controller that selectively inhibits release of an uplink resource in order to meet requirements of a delay-sensitive data application, such as a VoIP or streaming application. In one embodiment, the uplink resource release controller causes dummy blocks to be written to a data buffer to prevent initiation of a countdown process. By intelligently controlling resource release, delay-sensitive data may be transmitted in a more reliable fashion, thereby increasing application performance.
