Mobile Device Voice Call Prioritization During Data Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices are limited in allowing simultaneous voice and data calls, with voice calls being restricted during active data communication sessions, leading to missed time-critical calls during less critical data communications.
Innovation Solution
The mobile device prioritizes voice calls by immediately forcing a connected data service into a dormant state when a voice call request is made, tearing down the traffic channel to establish a new voice call and resuming data communications when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the mobile device maintains a connected data communication service, then data communication continuity is improved, but voice call capability deteriorates (voice calls cannot be placed or received)
Solution Approach 1:
The system dynamically transitions the data communication service between connected and dormant states based on incoming voice call requests. When a voice call is requested, the system dynamically switches the data service from connected to dormant state, allowing voice call processing while maintaining the ability to resume data communication after the call completes.
2Use of energy by moving object
If the mobile device waits for data inactivity timeout to enter dormant state, then energy consumption is reduced, but voice call response time deteriorates (time-critical calls may be missed)
Solution Approach 1:
The system performs preliminary action by immediately transitioning the data service to dormant state upon receiving a voice call request, rather than waiting for the inactivity timeout period to expire. This preliminary state change ensures that voice calls are processed without delay while the system prepares to resume data communication efficiently after the call.
3Speed
If the mobile device forces connected data service into dormant state immediately, then voice call processing speed is improved, but data communication interruption increases
Solution Approach 1:
The system temporarily discards the connected data service state by transitioning it to dormant state to accommodate voice call processing. After the voice call completes, the system recovers the data communication by transitioning back to connected state, ensuring both voice call priority and data communication continuity are maintained.

AI summary
Methods and apparatus for prioritizing voice call requests during data communication sessions involving a mobile communication device are disclosed. In one illustrative example, an end user invokes a voice call request though a user interface of the mobile device. If this request is made while the mobile device is engaged in a connected data communication service, the mobile device immediately forces the connected data service into a dormant state. In particular, a release order is transmitted to tear down a traffic channel of the connected data service so that the voice call request can be processed. Subsequently, a voice call with the mobile device is established using a new traffic channel. When the voice call is completed, data communications will resume if needed. Advantageously, the mobile device prioritizes voice calls over data communication sessions which may be deemed less time-critical.
