VoWiFi Voice Packet Reception With Individual Wake-Up Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Voice over Wi-Fi (VoWiFi) technologies consume excessive power and incur delays due to frequent identification frame transmissions between workstations and access points during voice packet reception.
Innovation Solution
Implementing an Individual Target Wake-Up Time (iTWT) mechanism to synchronize the workstation and access point, allowing them to automatically enter an awake state at predetermined intervals to receive voice packets, reducing unnecessary interactions and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identification frames are transmitted frequently to maintain VoWiFi service, then service reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic wake-up cycles where the workstation alternates between sleep and awake states at predetermined intervals. During awake states, identification frames are transmitted to maintain service reliability; during sleep states, power consumption is minimized. This periodic action resolves the contradiction by making identification frame transmission time-bound rather than continuous.
Solution Approach 2:
The workstation preliminarily transmits identification frames during awake states before entering sleep state, ensuring service reliability is maintained for the next wake-up cycle. This preliminary action allows the system to prepare for potential communication needs in advance, reducing the need for frequent continuous transmissions.
2Reliability
If identification frames are transmitted frequently to maintain VoWiFi service, then service reliability is improved, but delay time increases
Solution Approach 1:
By implementing periodic wake-up cycles with predetermined intervals, the system reduces the frequency of identification frame transmissions while maintaining service reliability. This periodic approach eliminates unnecessary delays caused by frequent transmissions, resolving the contradiction between reliability and delay time.
3Reliability
If the workstation remains in awake state continuously to receive voice packets, then reception reliability is improved, but power consumption increases
Solution Approach 1:
The workstation implements periodic wake-up cycles, entering awake states at predetermined intervals to receive voice packets and returning to sleep states otherwise. This periodic action ensures reception reliability is maintained during awake states while minimizing power consumption during sleep states, resolving the contradiction between reliability and energy use.
Solution Approach 2:
The workstation autonomously manages its own wake-up and sleep cycles based on predetermined intervals, without requiring continuous external control. This self-service approach allows the system to automatically balance reception reliability with power consumption optimization.

AI summary
Provided are a method and apparatus for receiving a voice packet, a terminal, a medium, and a computer program, belonging to the technical field of communication. After the wireless voice VoWiFi service is successfully established, an individual target wake-up time (iTWT) between a wireless access point AP and a workstation can be established based on an interaction period of the voice packet of the service. After the iTWT between the workstation and the AP is established, the workstation can automatically enter the wake-up state to receive voice packet when reaching the iTWT time period. Since the TWT mechanism is introduced in the VoWiFi service, the workstation can receive the voice packet transmitted by the wireless access point AP after being awakened on time by the iTWT. The workstation can be awakened on time without transmitting an identification frame to the wireless access point after being awakened.
