Voice over internet protocol system and related wireless local area network device

Abstract

A voice over Internet protocol (VoIP) system. The system includes a first device and a second device. The first device is disposed in a wireless local area network (WLAN) and connected to an Internet, for performing voice communication with a remote device through the Internet. Additionally, the first device processes audio information received during the voice communication to generate at least a playback audio packet, sends out the playback audio packet through the WLAN, receives at least a captured audio packet through the WLAN, and processes the captured audio packet to generate audio information to be sent out during the voice communication. The second device is disposed in the WLAN, for receiving the playback audio packet through the WLAN, playing audio information contained in the playback audio packet, capturing outside audio information to generate the captured audio packet, and sending out the captured audio packet through the WLAN.

Description

technical field [0001] The present invention relates to a wireless local area network, in particular to a voice transmission system using the Internet protocol of the wireless local area network and related wireless local area network devices. Background technique [0002] With the advancement of Internet (Internet) related technologies, various Internet-based applications have become more and more common. For example, Internet Protocol (Voice over Internet Protocol, VoIP) and Internet Protocol (Video over Internet ) are two common examples. [0003] Through VoIP-related technologies, a device connected to the Internet will be able to communicate with another device via the Internet. The aforementioned devices are not limited to electronic devices such as personal computers or notebook computers that can be directly connected to the Internet. In fact, with the advancement of technology, mobile phones and traditional phones (that is, installed on the Public Switched Telephon...

AI Technical Summary

Problems solved by technology

[0009] Since the VoIP phone 100 (especially its intermediary software layer 140) has a complex architecture and is responsible for performing many complex operations, higher-level hardware must be used to construct the VoIP phone 100, which will increase the overall cost. In addition, , when each functional block performs complex calculations, it will cause huge power consumption (Power Consumption), and reduce the use / standby time of the VoIP phone 100

In summary, although the known VoIP phone 100 has good mobility, its expensive selling price and excessive power consumption are the main problems that make consumers discouraged.
