Description

A kind of more voice converged communication method based on Android platform
Technical field
The present invention relates to voice communication technology field, more particularly to a kind of more voice converged communication system based on Android platform System is specially a kind of while supports satellite communication, private network communication (cluster intercommunication, ELTE etc.), the voice of public network mobile communication to lead to Letter method.
Background technology
With the development of current mechanics of communication, there is increasing communication apparatus, it is generally the case that existing multi-functional The voice communication method that communication equipment uses is, (i.e. mobile public usually using carrier network when being conversed with other equipment Net) conversed, or using area intercommunication network (i.e. private network) carries out intercommunication call.But existing voice communication method can not Region intercommunication function is realized using carrier network, region intercommunication real-time performance public network mobile communication function can not be utilized.This Larger limitation in actual use be present in the voice communication mode of sample.In order to overcome above-mentioned limitation, public network is designed The terminal that (2G/3G/4G mobile phone communications) and private network (intercom call) coexist, this kind of terminal are mostly " have intercom concurrently The mobile phone of function ", i.e., an intercom module is added in mobile communication chip, its major function is mobile phone, and intercom belongs to Auxiliary function.
Although this mobile phone for having intercom function concurrently, solves the problems, such as that public network is public with private network, also exist with Lower defect：
1) have concurrently in the mobile phone of intercom function this Terminal Type, private network (intercom function) is public network (cell-phone function) An accessory, be mainly used in a kind of standby call mode when public network (cell-phone function) dtr signal, it is not It is suitable for needing public network and all effective situation of private network call mode under any circumstance.
2) mobile phone for having intercom function concurrently is the communication mode for realizing the integrated talkback machine function on mobile phone, to sound Display system is not made and is correspondingly improved so that actual use sound effect is had a greatly reduced quality.
The content of the invention
In order to overcome defect present in prior art, it is logical that the present invention provides a kind of more voice fusion based on Android platform Letter system, on the same communication equipment of Android platform is run on, the first communication pattern can be both realized using first passage, also may be used Realize the second communication pattern.That is, using public network mobile communication module, it can both realize that the mobile voice of this equipment and other equipment led to Letter, also can realize that region radio voice communicates with the equipment based on cluster module.
The technical solution of the present invention：
A kind of more voice converged communication method based on Android platform, it, which is characterized in that, comprises the following steps：
