IP voice communication falling back method, apparatus, system and terminal equipment thereof

Abstract

The invention discloses an IP voice communication falling back method, an apparatus, a system and terminal equipment thereof. During an IP voice communication process, communication quality under a changeable network environment is guaranteed. The IP voice communication falling back system comprises the terminal equipment and a clicking dialing service server, wherein the terminal equipment is used for monitoring whether network quality of a current bearing network of IP voice communication satisfies a preset IP voice communication condition during the IP voice communication process; when the network quality of the current bearing network of the IP voice communication is monitored not to satisfy the preset IP voice communication condition, a clicking dialing service request is sent to the clicking dialing service server and the clicking dialing service request carries a first calling number and a first called number of the current IP voice communication or a preset second calling number and a second called number; and the clicking dialing service server is used for establishing voice communication of a calling subscriber and a called subscriber according to the first calling number and the first called number or the second calling number and the second called number.

Description

technical field [0001] The present invention relates to the technical field of IP voice calls, in particular to an IP voice call fallback method, device, system and terminal equipment. Background technique [0002] VoWiFi (Voice over WiFi) call is a kind of IP voice call. It digitizes the analog signal and realizes real-time communication on the IP network or the Internet through exchange processing such as voice compression coding, packaging and grouping, distribution routing, storage exchange, unpacking and decompression, etc. voice communication. Since VoWiFi technology is a voice transmission solution developed on the basis of the Internet, it is a connectionless application, and its data transmission follows a "best effort" principle. After the remote end sends out, the path it passes through is uncertain, the delay cannot be guaranteed, and the packet loss is also unpredictable. The network delay and delay jitter change with the quality of the network, which is unpred...

AI Technical Summary

Problems solved by technology

[0003] However, in practical applications, the quality of VoWiFi voice calls is only one of the factors that affect the quality of VoWiFi calls. The quality of the call is degraded during the process. For example, if the user moves out of the coverage area of ​​the WiFi network during the VoWiFi call, the VoWiFi call will be interrupted at this time, so that the quality of the user's voice call cannot be guaranteed
