Coordinating Radio Events to Optimize Battery Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless user equipment, there is a high electrical current draw when connecting to the network to send brief data messages, and the UE lacks control over radio resource teardown in networks like UMTS, leading to inefficient battery life and network resource usage.
Innovation Solution
The method involves dovetailing 'keep alive' messages with other network events or normal usage, such as voice calls, by monitoring opportunistic events to send these messages concurrently, thereby reducing overall current draw and eliminating unnecessary transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE sends keep-alive messages separately from other network events, then the presence information is maintained, but the electrical current draw increases and battery life decreases
Solution Approach 1:
The patent combines the transmission of keep-alive messages with other network events such as voice calls or data transmissions. By merging these separate transmission events into a single radio connection establishment, the UE avoids multiple separate connection setups, thereby reducing electrical current draw while maintaining presence information updates.
2Reliability
If the UE connects to the network frequently to send brief data messages, then the messages are transmitted reliably, but the battery consumption increases due to repeated connection setup
Solution Approach 1:
The patent merges multiple brief data message transmissions into a single extended radio connection by coordinating with other network events. This approach ensures reliable message delivery while avoiding repeated connection setup overhead, thereby extending battery life.
Solution Approach 2:
The UE proactively monitors for upcoming network events and prepares to send keep-alive or data messages during these events. By anticipating transmission opportunities in advance, the UE can batch multiple messages into single connection events, reducing the frequency of connection setup and extending battery operation.
3Speed
If the radio connection is maintained for brief data messages, then the messages are sent with low latency, but the network resources are wasted due to premature teardown
Solution Approach 1:
The patent combines multiple transmission events into a single extended radio connection by coordinating with other network events such as voice calls or data sessions. This merging approach maintains the connection longer than individually required, reducing teardown/setup overhead and optimizing network resource utilization while preserving low latency for message transmission.
