Invention patent application numbers disclosed by China Intellectual Property Office CN1753535A ("PHS and GSM or PHS and CDMA dual-mode dual-standby mobile phone and its combination method"), CN1585541A ("multi-mode mobile phone and its mode switching method"), CN1604674A ( "Separable dual-mode mobile phone"), CN1585507A ("automatically switching communication mode method") also only propose how to realize the combination of dual modes, how to realize simultaneous standby and how to realize the mode selection method under the standby state, System switching in the communication state cannot be realized
Therefore, when the user uses dual-mode dual-standby to communicate (incoming or outgoing calls) and meets the predetermined system switching conditions (such as reaching the coverage edge of the communication mode, or the signal quality is poor, or the network needs to adjust the business load, etc.) When the communication mode cannot be switched from the communicating system to the system belonging to another mode, the communication will be interrupted

Embodiment Construction

[0029] Below in conjunction with Fig. 1-Fig. 7 provide preferred embodiment of the present invention, take TD-SCDMA / GSM dual-mode dual-standby mobile phone in communication process from TD-SCDMA to GSM switching as example to describe technical scheme of the present invention in detail, It is intended to make it easier for those skilled in the art to understand the process, structural features and functional features of the present invention, rather than to limit the scope of the present invention.

[0030] As shown in Figure 1, the dual-mode dual-standby mobile phone has a mode A subsystem 106 and a mode B subsystem 111, the mode A subsystem has a baseband system 102, a radio frequency system 101 and an antenna 103; the mode B subsystem has a baseband system 109, a radio frequency System 108 and antenna 110 . Since the Mode A subsystem and the Mode B subsystem have their own independent baseband, radio frequency and antenna subsystems, the two modes can work simultaneously an...

Abstract

A system switching method and a structure of a double mode double wait™½€ú™½ˆ² mobile phone in communication are provided, which are characterized in that: when one mode is in communication (being called or calling), satisfies predetermined system switching conditions, the double mode double wait mobile phone switches automatically or user arrangment to the second mode to communicate continuously, the continue communication is realized.

Description

technical field [0001] The invention relates to a mobile communication mobile phone technology, in particular to the call processing and switching between handover systems in a dual-mode dual-standby mobile phone. Background technique [0002] At present, mobile communication technology has been widely used all over the world. The actually deployed mobile communication networks include GSM network, CDMA network and PHS network belonging to the 2nd or 2.5th generation, and CDMA2000, WCDMA and TD belonging to the 3rd generation. -SCDMA network. For the application of these networks, various dual-mode dual-standby mobile phones have emerged. Invention patent application numbers disclosed by China Intellectual Property Office CN1753535A ("PHS and GSM or PHS and CDMA dual-mode dual-standby mobile phone and its combination method"), CN1585541A ("multi-mode mobile phone and its mode switching method"), CN1604674A ( "Separable dual-mode mobile phone"), CN1585507A ("automatically s...
