Suspended Baseband State for Wireless Resource Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face excessive resource drain and negative user experiences due to repeated establishment and tearing down of push connections caused by weak signal strength, leading to inefficient resource management and delayed message delivery.
Innovation Solution
Implementing a suspended baseband state in user equipment devices, where the connection is gracefully terminated and resumed based on signal strength thresholds, allowing for reduced resource usage and minimized handshake procedures, thereby optimizing communication during weak signal conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the push connection is maintained during weak signal conditions, then message delivery can resume immediately when signal improves, but excessive resource drain occurs due to repeated connection establishment and teardown
Solution Approach 1:
The system dynamically adjusts the connection state based on signal conditions. When signal strength falls below a threshold, the connection is suspended rather than torn down completely. This dynamic state change allows the system to maintain connection context during weak signal periods while avoiding the resource drain of repeated full connection cycles, resolving the contradiction between reliability and energy consumption.
Solution Approach 2:
The invention changes the connection state parameter from binary (established/terminated) to ternary (established/suspended/terminated). By introducing a suspended state where connection context is preserved but data transmission is paused, the system maintains message delivery readiness while reducing resource consumption during weak signal conditions.
2Loss of energy
If the push connection is repeatedly established and torn down due to weak signal, then resource consumption increases, but connection reestablishment complexity must be minimized
Solution Approach 1:
The system performs preliminary suspension of the connection when signal weakness is detected, preserving connection context and state information before complete teardown would occur. This preliminary action prevents the need for complex reestablishment procedures by maintaining the connection framework, thereby reducing both resource consumption and management complexity.
Solution Approach 2:
The invention extracts the essential connection context and state information from the full connection, allowing the system to maintain minimal connection metadata during suspension. This extraction enables simple resumption by restoring data transmission using preserved context, avoiding complex rehandshaking while minimizing resource usage.
3Use of energy by moving object
If connection suspension is implemented to reduce resource usage, then resource consumption decreases, but connection resumption procedures become more complex
Solution Approach 1:
The system creates a copy or snapshot of the connection state and context information when suspension occurs. This copied state is preserved during the suspended period, enabling simple resumption by restoring from the saved context rather than performing complex rehandshaking. The copying mechanism reduces resumption complexity while maintaining resource conservation benefits.

AI summary
A user equipment (UE) device and associated methods for entering a suspended baseband state in response to a signal strength indicator falling below a threshold. A UE engages in an active connection with a remote server, which may be a transmission control protocol (TCP) push connection. A baseband layer of the UE determines that the signal strength indicator has fallen below a threshold, and transmits a notification to an application layer of the UE to suspend the connection. The baseband layer may later determine that the signal strength has risen above a second threshold, whereby the UE may resume the suspended connection. The UE may maintain state information associated with the connection during the suspended state, such that the UE may resume the suspended connection without reestablishing a new connection with the remote server.
