Wireless VOIP voice frame combining method as well as radio device

Abstract

The invention relates to a method for combining wireless VoIP voice frames, comprising: determining the combination number of the voice frames based on wireless channel quality parameter and generating the voice frames according to the combination number of the voice frames. Further disclosed is a wireless device including a wireless network communication module, a voice coding module, a voice decoding module, a protocol processing module, a physical link monitoring module and a voice frame combining and controlling module. The physical link monitoring module is connected with the wireless network communication module for detecting the intensity of the received signal; the voice frame combining and controlling module is connected with the wireless network communication module, the voice coding module and the protocol processing module for determining the combination number of the voice frames according to the received signal intensity and combining the voice frames generated by the voice coding module. The invention can automatically regulate the combination number of the voice frames based on the present channel transmission quality to effectively increase the utilization rate ofthe wireless channel as well as be suitable to the change of the physical channel.

Description

technical field [0001] The invention relates to wireless VoIP technology, in particular to a wireless VoIP voice frame combination method and a wireless device capable of realizing voice communication based on a wireless access mode. Background technique [0002] With the development of wireless communication technology and voice communication technology, the application of wireless voice technology using wireless network to provide voice service has emerged. Voice over Wireless Local Area Network (VoWLAN) technology is one of them. VoWLAN utilizes Wireless Local Area Network (WLAN for short) to realize wireless IP (Voiceover Internet Protocol, VoIP for short) calls, and users can make voice calls at any time within the coverage of WLAN network through VoWLAN terminal equipment. The wireless voice technology not only takes advantage of the low-cost characteristics of IP networks, but also enables users to obtain the convenience brought by wireless access methods.

Problems solved by technology

However, the wireless channel in WLAN is a time-varying unreliable channel, which is easily affected by various factors such as multipath, co-channel interference, and terminal mobility. The existing voice frame combination technology does not consider the unreliability of WLAN wireless channels Due to the changeable characteristics and the particularity of the WLAN MAC access mechanism, the combination of voice frames is only based on the factors of the application layer. When the channel quality is degraded, a large number of voice frames are still combined, which may be due to the lengthening of the data frame. This increases the probability of frame transmission errors, and at the same time, when data conflicts occur, it will cause the loss of multiple consecutive voice frames, seriously deteriorating the voice quality
