Mobile Device Voice Data Connection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile wireless communication devices face challenges in effectively managing voice and data connections, particularly in networks that do not support simultaneous connections, leading to dropped data connections and inefficient resource utilization due to improper termination of data connections during voice call origination.
Innovation Solution
A method where a mobile wireless device receives a voice connection redial request, closes the existing data connection, tunes to a second voice connection channel radio frequency different from the data connection frequency, and establishes a voice connection, ensuring that data connections are not dropped and resources are utilized efficiently by properly managing the switching between voice and data channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile wireless device rapidly switches between voice and data connections to provide both services with minimal interruption, then the user can access both voice and data services, but the data connection may terminate improperly resulting in dropped data connections and wasted network resources
Solution Approach 1:
The mobile wireless device closes the data connection before initiating voice call origination. This preliminary action ensures that the data connection is properly terminated before the voice connection is established, preventing improper termination and dropped connections while maintaining both service availabilities
Solution Approach 2:
The device monitors the connection state and uses feedback from the voice connection status to control the data connection. When a voice connection is established or attempted, the device receives feedback and accordingly closes the data connection to avoid resource conflicts and improper termination
2Adaptability or versatility
If the mobile wireless device maintains both voice and data connections simultaneously in networks that support it, then service versatility is improved, but network resource utilization becomes inefficient when connections cannot coexist
Solution Approach 1:
The device closes the data connection before initiating voice call origination. This preliminary action ensures that the data connection is properly terminated before the voice connection is established, preventing improper termination and dropped connections while maintaining both service availabilities
Solution Approach 2:
The device discards the data connection when a voice connection is needed, and can recover the data connection after the voice connection terminates. This approach optimizes network resource utilization by ensuring that only one connection type occupies the channel at a time, preventing resource wastage while maintaining service versatility

AI summary
Controlling non-simultaneous voice and data connections between a mobile wireless device and a wireless network is described. Following a voice connection origination failure between the mobile wireless device and the wireless network, the mobile wireless device sends a voice connection redial request only after closing an existing data connection between the mobile wireless device and the wireless network. The mobile wireless device tunes a wireless transceiver to a second voice connection channel radio frequency that differs from a first data connection channel radio frequency and establishes a voice connection with the wireless network on the second voice connection channel radio frequency.
