With reference to Fig. 1 the audio data transmission method that proposes according to first aspect present invention embodiment is described below.
As shown in Figure 1, this audio data transmission method may further comprise the steps:
S101, first equipment obtains voice data waiting for transmission.
In one embodiment of the invention, first equipment can be portable terminal.Particularly, portable terminal can be mobile phone, panel computer, but is not limited only to this.Voice data refers to the data of transmitting through the audio frequency mode.Wherein, voice data waiting for transmission can be the identification data of set form, and for example: the identification data of this set form has identified the modulation system that voice data waiting for transmission adopts; Voice data perhaps waiting for transmission can be for containing the transmission data of variable content, for example: the transmission data of variable content are the various data of normal need transmission, for example: various data such as user profile, Transaction Information.
