Embodiment 1

[0038] According to an embodiment of the present invention, a voice switching method based on dual-mode / multi-mode is provided. The method is used for voice switching of the calling terminal when the calling terminal is talking with the called terminal.

[0039] figure 2 A schematic diagram of voice switching by a calling terminal is shown. The calling terminal takes a WiMAX and 3G dual-mode terminal as an example, and the called terminal takes a CDMA and GSM dual-mode terminal as an example. When the calling terminal enters an area with weak signal strength, the terminal will decide whether to perform network switching according to the signal strength. figure 2 shows the process of a WiMAX user calling a GSM user. Wherein, 201 is a call initiation process, 202 the calling server notifies the called server of the user to be called, and 203 the called server notifies the called terminal to establish a call. When the WiMAX signal strength is less than a certain threshold, th...

Embodiment 2

[0053] According to an embodiment of the present invention, a voice switching method based on dual-mode / multi-mode is provided, and the method is used for voice switching of the called terminal when the calling terminal is talking with the called terminal.

[0054] Figure 5 It is a schematic diagram of voice switching by the called terminal. The calling terminal takes a WiMAX and 3G dual-mode terminal as an example, and the called terminal CDMA and GSM dual-mode terminal as an example. When the called terminal enters an area with weak signal strength, the called terminal will decide whether to perform network switching according to the signal strength. Figure 5 shows the process of a WiMAX user calling a GSM user. 501 is the call initiation process, 502 is the calling server notifying the called server of the user to be called, and 503 the called server notifying the called terminal to establish a call with the calling server. When the GSM signal strength of the called ter...

Abstract

The invention discloses a sound switching system based on a double mode / multimode system and a method. The sound switching system comprises a timer, a threshold value comparison module, a channel monitor module, a sound switching module, a network switching module, a network registration module, a re-dial module, callback module, an automatic answering module, and a sound controller, wherein, thetimer is used for monitoring the network signal and recording the pilot signal strength value of the network signal; the threshold value comparison module is used for comparing the pilot signal strength value recorded by the timer with the scheduled threshold value; the channel monitor module invoked by the threshold value comparison module is used for monitoring whether the sound channel is engrossed; the sound switching module invoked by the threshold comparison module is used for releasing the channel and invoking the network switching module to process the network switch; the network switching module is used for processing the network switch; the network registration module is used for processing the network registration; the re-dial module is used for a calling terminal beginning a call again; the callback module is used for a called terminal carrying through a callback to the calling terminal that begins the call; the automatic answering module is used for automatically communicating the called terminal; the sound controller positioned in the side of the server is used for carrying through a voice prompt in the process of the network switch.

Description

technical field [0001] The present invention relates to a dual-mode or multi-mode voice switching technology for mobile terminals, in particular to a dual-mode / multi-mode voice switching system and method for SIP (Session Initiation Protocol, Session Initiation Protocol) terminals. Background technique [0002] With the continuous development of information technology, mobile terminal products emerge in an endless stream, and people's requirements for voice call quality are also getting higher and higher. Dual-mode / multi-mode technology has been developed to a certain extent. For example, common mobile terminal standards include CDMA (Code Division Multiple Access, Code Division Multiple Access) / GSM (Global System for Mobile Communication, Global System for Mobile Communications) dual-mode, CDMA / 3G dual-mode, WiMAX (Worldwide Interoperability for Microwave Access, global interoperability for microwave access) / 3G dual-mode, WiMAX / EVDO (Evolution Data Only, data transmission o...
