Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing voice call methods using Bluetooth technology are limited in data transmission capacity, failing to meet call requirements in scenarios needing a larger amount of data transmission.
Innovation Solution
Establishing a Wi-Fi link between a mobile phone and a peripheral device to transmit audio signals, allowing for higher data capacity and improved call efficiency and quality, while maintaining control signaling through a Bluetooth link to ensure reliability and low power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a Bluetooth link is used to transmit audio signals between the mobile phone and peripheral device, then the connection is reliable and power consumption is low, but the data transmission capacity is limited and cannot meet high-quality call requirements
Solution Approach 1:
The patent divides the transmission link into two separate links: a Bluetooth link for control signaling and a Wi-Fi link for audio data transmission. This segmentation allows each link to be optimized for its specific function, with Bluetooth providing reliable low-power control and Wi-Fi providing high-bandwidth audio transmission, thereby resolving the contradiction between data capacity and connection reliability.
Solution Approach 2:
The mobile phone acts as an intermediary device that receives call signals from the network, establishes both Bluetooth and Wi-Fi links with the peripheral device, and routes control signaling through Bluetooth while transmitting audio data through Wi-Fi. This intermediary role enables the system to leverage the strengths of both communication technologies simultaneously.
2Quantity of substance
If a Wi-Fi link is established for audio transmission, then data transmission capacity increases, but power consumption and device complexity increase
Solution Approach 1:
The patent segments the communication functions by using Wi-Fi exclusively for audio data transmission while using Bluetooth for control signaling. This allows the high-power Wi-Fi link to be used only when necessary for audio transmission, while the low-power Bluetooth link handles control functions, thereby reducing overall power consumption compared to using Wi-Fi for all communications.
3Adaptability or versatility
If Bluetooth technology is used for voice calls, then the system is simple and widely compatible, but it cannot meet call requirements in scenarios needing a relatively large amount of data transmission
Solution Approach 1:
The patent makes the communication system multi-functional by enabling it to use both Bluetooth and Wi-Fi links simultaneously for different purposes. The system can maintain Bluetooth for universal compatibility and control functions while adding Wi-Fi capability for high-data-capacity audio transmission, thereby adapting to diverse call scenarios including high-quality audio requirements.

AI summary
This application relates to the field of mobile communications, and provides a voice call method, an electronic device, and a system, to resolve a problem that when an audio signal is transmitted through a voice link established between a mobile phone and a peripheral device by using a Bluetooth technology, a call requirement in a scenario in which a relatively large amount of data needs to be transmitted cannot be met. The voice call method may include: A mobile phone establishes a Bluetooth link to a notebook computer according to a Bluetooth protocol. The mobile phone receives call request information, and sends the call request information to the notebook computer through the Bluetooth link. The two electronic devices establish a Wi-Fi link according to a Wi-Fi protocol. The mobile phone receives an answer command sent by the notebook computer through the Bluetooth link, sends the answer command to a third electronic device, establishes a call with the third electronic device, receives a downlink audio signal, and sends the downlink audio signal to the notebook computer through the Wi-Fi link. In the foregoing technical solutions, the audio signal in the call is transmitted through the Wi-Fi link, so that quality and call efficiency of the call on the mobile phone are improved.
