Buffering Data Transmissions for Constrained User Equipment Voice Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Constrained user equipment (UE) such as wearables face performance degradation due to limited power supply and antenna constraints, leading to issues with voice and data transmission during voice calls, which can result in a poor user experience.
Innovation Solution
Implementing a method where UE and network components buffer data transmissions during voice calls to prevent interruptions, utilize a forgiving call establishment procedure, adaptive paging, and proactive handover procedures to optimize performance under constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is performed during voice calls in constrained UE, then data communication capability is maintained, but voice call quality deteriorates due to interruptions and resource conflicts
Solution Approach 1:
The network buffers downlink data transmissions before the voice call starts, and the UE buffers uplink data transmissions before the voice call starts. This preliminary buffering action ensures that data is ready to be transmitted without interrupting the voice call, resolving the conflict between maintaining data capability and ensuring voice quality.
Solution Approach 2:
The transmission resources are segmented into dedicated voice resources and dedicated data resources. Voice packets are transmitted on voice resources while data packets are transmitted on data resources, allowing both functions to operate simultaneously without interference, thus maintaining both voice call quality and data transmission capability.
2Volume of moving object
If smaller batteries are used to achieve streamlined device design, then device form factor is improved, but power supply capacity deteriorates leading to performance loss
Solution Approach 1:
The system changes the operational parameters by implementing buffering mechanisms that allow data transmissions to be postponed during voice calls. This parameter change in transmission timing allows the constrained UE with limited battery capacity to maintain performance by avoiding simultaneous high-power voice and data transmissions.
3Shape
If internal antennas are used to maintain device form factor, then device design is simplified, but antenna length is reduced causing performance degradation
Solution Approach 1:
The patent creates a virtual representation of antenna performance through buffering and resource allocation strategies. Instead of physically extending the antenna, the system compensates for the reduced antenna length by managing transmission resources to ensure adequate signal quality, effectively copying the performance characteristic without the physical constraint.

AI summary
A user equipment (UE) and associated method performs a voice call with a network, including exchanging voice packets, determines an uplink data transmission to be performed concurrently with the voice call and stores the uplink data transmission in a buffer. A base station and associated method performs a voice call with a UE, determines a downlink data transmission for the UE is to be performed concurrently with the voice call and stores the downlink data transmission in a buffer when the UE is a predetermined type. A UE and associated method associates with a first access point (AP), determines first performance characteristics of a connection with the first AP, determines second performance characteristics of a potential connection with a second AP, declares a radio link failure when the second performance characteristics exceed the first performance characteristics to trigger a handover procedure from the first AP to the second AP.
