Wireless Session Extension via Heartbeat Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication, the frequent cessation and initiation of communication sessions between devices result in increased power consumption due to the need for repeated radio resource control (RRC) connections and disconnections, especially in cases involving data packets with longer latency.
Innovation Solution
The proposed solution involves extending wireless communication sessions, such as small data transmit (SDT) sessions, instead of ending them and starting new sessions. This is achieved by transmitting 'heartbeat' packets or scheduling requests after a period of inactivity, which keeps the communication session active and prevents the network from releasing the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If communication sessions are frequently ceased and re-initiated to handle data packets with longer latency, then the connection management becomes simpler, but power consumption increases
Solution Approach 1:
The patent maintains communication sessions in an active state even during periods without data transmission by implementing mechanisms to prevent session expiration. This continuity approach keeps the RRC connection alive, avoiding frequent re-establishment overhead while reducing power consumption associated with session management.
Solution Approach 2:
The system performs preliminary actions by sending data packets in advance before the communication session would naturally expire. This proactive transmission prevents session termination and subsequent re-establishment, thereby reducing the frequency of connection management operations and associated power consumption.
2Use of energy by moving object
If communication sessions are extended to reduce power consumption, then energy efficiency improves, but session management complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the system monitors data transmission patterns and session status, then adjusts session management decisions accordingly. This feedback loop enables intelligent extension or termination of sessions based on actual communication needs, managing complexity through adaptive control rather than rigid rules.
Solution Approach 2:
The communication session management is made dynamic by allowing sessions to be extended or terminated based on real-time conditions such as data arrival patterns and latency requirements. This dynamic approach adapts session duration to actual needs, balancing power consumption benefits with manageable complexity through condition-based decision-making.

AI summary
An electronic device includes a transceiver and processing circuitry that is operatively coupled to the transceiver. The processing circuitry is configured to transmit, via the transceiver and to a second electronic device, a request for a wireless communication session with the second electronic device. The processing circuitry is also configured to communicate, via the transceiver, one or more first wireless signals during the wireless communication session with the second electronic device. Additionally, the processing circuitry is configured, after communicating the one or more first wireless signals, to extend the wireless communication session by transmitting, via the transceiver and to the second electronic device, one or more second wireless signals based on no wireless signals being communicated via the wireless communication session for a duration of time.
