Automatic Response Timer for Wireless Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, automatic call drops occur when users fail to respond to mode switch requests from speech to multimedia within the predetermined time frame, leading to frustration for both parties due to lack of awareness or inability to respond promptly.
Innovation Solution
Implementing an automatic response timer set to a shorter duration than the call drop timer, which generates a signal prompting the user to respond and automatically declines the request if no response is received, preventing call drops by deactivating the call drop timer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a call drop timer is used to automatically disconnect calls when no response is received, then call management efficiency is improved, but unintentional call disconnections occur when users fail to respond to mode switch requests
Solution Approach 1:
The system performs preliminary actions by sending a preliminary signal to prompt the user to respond before the call drop timer expires. This preliminary prompt gives the user advance notice and opportunity to respond, preventing unintentional call disconnections while maintaining the efficiency benefits of the timer-based call management system.
2Ease of operation
If the network prompts the remote user to confirm mode switch from speech to multimedia, then user privacy and control are improved, but call drops occur when users do not respond within the timer period
Solution Approach 1:
The system sends a preliminary signal to the remote user before the call drop timer expires, providing advance notification and opportunity to respond. This resolves the contradiction by maintaining user control over the mode switch decision while preventing unnecessary call drops due to timer expiration, thus avoiding loss of call duration.
3Ease of operation
If automatic mode switch from multimedia to speech is enabled, then call setup simplicity is improved, but user awareness and confirmation opportunities are reduced
Solution Approach 1:
The system implements feedback by sending a signal to prompt the user when a mode switch is requested or occurring. This feedback mechanism ensures user awareness of mode changes while maintaining the simplicity of automatic switching, resolving the contradiction between ease of operation and user awareness.

AI summary
A technique is provided for use by a user terminal or mobile services switching center (MSC) for responding to a request to switch an on-going call from speech mode to multimedia mode within a wireless communication network conFig.d to automatically disconnect a call if a requested mode switch is not confirmed within a predetermined period of time specified by a call drop timer. In one example, the terminal or MSC activities an automatic response timer upon receipt of a request from a user to switch an on-going call from speech to multimedia, with the timer set shorter than the call drop timer. The user receiving the request is then prompted to accept or decline the request. If no response is received before expiration of the automatic response timer, the terminal or MSC automatically declines the request on behalf of the user so that the call drop timer does not expire.
