VoIP Terminal Power Management via Packet Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional VoIP terminal devices remain in a high power state to process packets, compromising their ability to enter a power-saving state and wake up from it, leading to increased power consumption and reduced battery life.
Innovation Solution
Implementing a system with a packet matching module and power management module that allows VoIP terminal devices to enter a power-saving state based on user actions or inactivity and wake up by comparing identification packets to reference packets, increasing operating power only when necessary to process incoming communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a VoIP terminal device remains in a high power state to process packets, then its ability to process signaling and user information transfer is maintained, but power consumption increases and battery life is reduced
Solution Approach 1:
The VoIP terminal device dynamically adjusts its power state based on operational requirements. The device transitions between a low power state (for battery conservation) and a high power state (for active packet processing), allowing it to adapt its power consumption to actual usage patterns while maintaining reliable communication when needed.
Solution Approach 2:
The device performs preliminary actions by entering a low power state in advance during periods of inactivity, and proactively wakes up to process incoming communications. This preliminary power management approach allows the device to conserve energy during idle periods while ensuring it is ready to handle communications when they arrive, resolving the contradiction between continuous operation and power saving.
2Use of energy by moving object
If a VoIP terminal device enters a power-saving state, then power consumption is reduced and battery life is extended, but its ability to process incoming communication packets is compromised
Solution Approach 1:
The packet processing function is segmented into two distinct operational modes: identification packet processing (performed in low power state) and content packet processing (performed in high power state). This segmentation allows the device to maintain basic communication awareness while saving power, and only fully activate when necessary to handle actual communication content.
Solution Approach 2:
The device performs partial packet processing in the low power state by examining only identification packets to determine whether full communication processing is needed. This partial action approach allows the device to maintain power-saving operation while still being able to selectively wake up for relevant communications, thus maintaining reliability without continuous high power consumption.
3Speed
If a VoIP terminal device continuously monitors for incoming packets, then communication responsiveness is improved, but energy consumption increases
Solution Approach 1:
The device employs periodic action by transitioning between sleep and wake states based on communication needs. Instead of continuous monitoring, the device periodically checks for incoming communications by processing identification packets in low power state, and only fully activates for content packet processing when necessary. This periodic operation maintains communication responsiveness while significantly reducing energy consumption compared to continuous monitoring.

AI summary
A VoIP terminal device is configured to enter a power-saving state upon the occurrence of a specified condition. The VoIP terminal device is further configured to wake up from the power-saving state when a communication associated with a specified communication operation is received by the VoIP terminal device. In particular, the operating power of the VoIP terminal device is increased to an extent sufficient to perform the specified communication operation.
