Embodiment 1

[0054] Such as figure 2 As shown, the embodiment of the present invention provides a terminal for automatically switching voice telephone services, the terminal comprising: a calling module 210, a switching selection module 220 and an IP network calling module 230;

[0055] The call module 210 is configured to send an IP service query message containing identification information of the calling terminal and the called terminal to the IP network service server when initiating a call to the called terminal through the PLMN network; and trigger disconnection based on the IP network call module 230 a call connection with said PLMN network;

[0056] The switch selection module 220 is used to receive and display the switch selection prompt message sent by the IP network service server, and send the user selection result to the IP network service server;

[0057] The IP network call module 230 is configured to trigger the call module 210 after receiving the notification message tha...

Embodiment 2

[0061] Such as image 3 As shown, the embodiment of the present invention provides an IP network service server, including:

[0062] The IP network service module 310 is used to inquire about the status of the calling and called terminals after receiving the IP service query message, and when the status of the calling and called terminals satisfies the preset call switching condition, send a message to the calling and called terminals The terminal sends a switching selection prompt message;

[0063] The path establishment module 320 is used to establish an IP network connection path between the calling terminal and the called terminal when both the calling terminal and the called terminal choose to switch calls, and notify the calling and called terminals.

[0064] Preferably, in this embodiment, the meeting of the preset call switching conditions in the IP network service module 310 includes: the service authority states of the calling terminal and the called terminal are bo...

Abstract

This invention discloses a method, a device and a system for automatically switching voice telephone business. The method comprises: a main calling terminal initiates calling to a called terminal through a PLMN network, and transmits IP business inquiry information containing identification information of the main calling terminal and the called terminal; the IP network business server inquires about the states of the main calling terminal and the called terminal, transmits switching selection prompting information to the main calling terminal and the called terminal when the states of the main calling terminal and the called terminal meet a preset communication condition, establishes an IP network communication path between the main calling terminal and the called terminal when the main calling terminal and the called terminal choose to switch communication, and notifies the main calling terminal and the called terminal; and the main calling terminal cuts off the call connection with a PLMN network when the main calling terminal receives the notification and utilizes the IP network connection path to perform IP network communication with the called terminal. The scheme of the invention improves the conversation tone quality and saves the calling money.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method, device and system for automatically switching voice telephone services. Background technique [0002] Traditional mobile voice calls are carried by PLMN (Public Land Mobile Network, public land mobile network). Due to unstable network quality, there will be situations where the signal is weak. At this time, the call effect is poor, and there will be dropped calls. [0003] With the development of mobile wireless networks and the diversification of access methods, the use of wireless data services is becoming more and more popular. Users can use mobile wireless networks to perform various data services including web browsing, social applications, instant messaging, etc. . With the development of instant messaging software, voice calls through the Internet are also gradually developed. [0004] At present, a known solution to the selection and switching of voice ...
