TDM Content Download Pausing for Call Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Time Division Multiplexing (TDM) based phones lack advanced functionalities and customizations, leading to a decline in their usage as consumers prefer feature-rich cellular and VoIP devices, resulting in a loss of subscribers and revenue for service providers.
Innovation Solution
Enabling the download of content such as ringtones and wallpapers over a TDM network through a web portal interfacing with a central office switch, allowing downloads to be paused and resumed during calls, ensuring uninterrupted telephone usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content download is enabled over TDM network, then device functionality and customization options are improved, but network bandwidth consumption increases and download speed decreases
Solution Approach 1:
The system dynamically adjusts download operations based on call state. When a call is active, the download is paused to prioritize voice communication bandwidth. When no call is active, the download proceeds at full speed. This dynamic state-dependent operation resolves the contradiction by making download speed adaptive to network conditions.
Solution Approach 2:
The download operation is performed periodically in intervals between calls rather than continuously. The system checks call state periodically and resumes/downloads content in available time windows, allowing voice traffic to take precedence while still enabling content delivery over the TDM network.
2Loss of time
If content download is performed continuously, then download completion time is reduced, but telephone call connectivity is interrupted
Solution Approach 1:
The system proactively pauses the download operation before a call can be interrupted by network resource contention. By detecting the call state and preemptively suspending data transmission, the system prevents potential call connectivity issues while still enabling download functionality during idle periods.
Solution Approach 2:
The download operation transitions between active and paused states based on real-time call detection. This dynamic state management ensures that downloads occur during idle periods without interfering with voice calls, resolving the contradiction between download speed and call reliability.
3Reliability
If download pausing functionality is added, then telephone usage reliability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a intermediary download management entity that acts as a mediator between the content delivery system and the telephone network. This intermediary component monitors call states and controls download operations, isolating the complexity of pause/resume logic from the core telephony functions while ensuring reliable call connectivity.
Data Source
AI summary
A telecommunications device and method for downloading content using Time Division Multiplexing (TDM) includes receiving a request for content to be downloaded using TDM. The content may be communicated in response to receiving the content request. In response to receiving a call request for use of a telephone line, a download status of the telephone line may be determined. If the download status of the telephone line is indicative of content being downloaded, the content may be suspended from being communicated to enable a call associated with the call request to be connected with the telephone line. Otherwise, if the download status of the telephone line is not indicative of content being downloaded, a call associated with the call request may be connected with the telephone line.
