Dynamic Resource Allocation for VoIP Silence Periods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face inefficiencies in resource allocation during silence periods in VoIP communications, leading to unnecessary resource usage and potential misinterpretation of silence as a dropped connection.
Innovation Solution
Implementing a method to dynamically allocate resources based on silence indications, temporarily stopping resource allocation during silence periods and adjusting resource sizes and periods from voice data to silence indication frames, and extending sleep windows during mutual silence periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If periodic resources are continuously allocated to mobile station during silence period, then resource allocation simplicity is maintained, but network resource efficiency deteriorates due to unnecessary resource usage
Solution Approach 1:
The patent implements dynamic resource allocation where the base station adjusts resource allocation based on the mobile station's activity state. When silence is detected, periodic resource allocation is temporarily stopped; when voice activity resumes, allocation is restarted. This dynamic adjustment resolves the contradiction by adapting resource allocation to actual needs rather than maintaining a fixed allocation pattern.
Solution Approach 2:
The mobile station provides feedback to the base station about its silence period status. The base station uses this feedback information to make informed decisions about whether to continue or stop periodic resource allocation. This feedback mechanism enables the system to balance resource efficiency with allocation simplicity by only adjusting resources when necessary.
2Productivity
If resources are temporarily stopped during silence period, then resource efficiency is improved, but communication reliability may deteriorate if silence is misinterpreted as dropped connection
Solution Approach 1:
The mobile station actively sends feedback signals to the base station indicating when it enters and exits silence periods. This feedback ensures that the base station understands the silence is intentional (e.g., during VoIP calls) rather than indicating a dropped connection. The resource allocation is temporarily stopped based on this reliable feedback, resolving the contradiction between efficiency and reliability.
Solution Approach 2:
The mobile station notifies the base station in advance before entering a silence period and notifies when exiting. This preliminary action allows the base station to proactively adjust resource allocation without misinterpreting the silence as a connection loss, thereby maintaining reliability while improving efficiency.
3Quantity of substance
If resource allocation is adjusted from voice data to silence indication frames, then resource usage is optimized, but system complexity increases due to dynamic adjustment requirements
Solution Approach 1:
The system dynamically adjusts resource allocation parameters based on the mobile station's state. During voice activity, full resource allocation is provided; during silence periods, allocation is reduced or stopped. This dynamic adjustment optimizes resource usage while the complexity is managed through automated state-based decision logic at the base station.
Solution Approach 2:
The patent changes resource allocation parameters (such as allocation size, periodicity, or grant duration) based on the detected state of the mobile station. When silence is detected, parameters are adjusted to reduce resource consumption; when voice activity resumes, parameters are restored. This parameter-based approach optimizes resource usage while maintaining manageable system complexity through standardized parameter adjustment mechanisms.

AI summary
Various example embodiments are disclosed herein. According to an example embodiment, a technique may include allocating periodic resources to a mobile station in a wireless network for transmission of voice data, receiving from the mobile station an indication of a start of a silence period, and adjusting, based on the receiving of the indication of a start of silence period, the allocating of the periodic resources from a size and period of resource for the voice data to a size and period of resource for a silence indication (SID) frame. Alternatively, in response to receiving an indication of a start of silence period, the allocating of periodic resources for the VoIP voice data may be temporarily stopped during the silence period.
