And for bidirectional call recording, because circuit 1 and circuit 2 are bidirectional line, upstream digital audio signal and descending digital audio and video signals can appear in AP module 804 simultaneously, now AP module 804 exports these two kinds of digital audio and video signals in digital audio mixing module 807 to, by 807 pairs of above-mentioned two kinds of digital audio and video signals of digital audio mixing module, decoded respectively, row decode signal and lower row decode signal in generation, and should go up row decode signal and lower row decode signal carries out recompile by digital audio mixing module 807, obtain digital audio signal, and this numeral audio signal is transmitted back to AP module 804, after processing via 804 processing of AP module, can obtain the bidirectional call recording file.Because normal talking has adopted circuit 1 and circuit 2, and Recording Process is carried out in AP module 804 and digital audio mixing module 807, makes both not there will be interactional phenomenon, improves the quality of conversation and recording.In addition, circuit 2, circuit 3 have adopted pcm bus or I2S bus, can certainly be other any bus or the circuits that can realize this transfer function.
As shown in Figure 9, for descending process, at first in the mobile terminal of user A, LTE module 902 receives the downlink voice data-signal sent from another user B, this downlink voice data-signal transfers to AP (processor) module 904 through circuit 1, and AP module 904 is converted to descending digital audio and video signals by this downlink voice data-signal; Then AP module 904 transfers to CODEC module 906 by circuit 2 by this descending digital audio and video signals, after CODEC module 906 is converted to descending simulated audio signal by this descending digital audio and video signals, export receiver 910 to as receiver, the call voice that user A can uppick user B.
And for up process, user A sounds as microphone to transmitter 908, transmitter 908 receives these voice and generates corresponding upstream digital audio signal, here directly during the generating digital audio signal, can be by realizing as transmitters such as digital microphones, this upstream digital audio signal is transferred to AP module 904 by circuit 4; AP module 904 is converted to the upstream voice data signal by this upstream digital audio signal, and transfers to LTE module 802 via circuit 1, then by LTE module 802, sends out this upstream voice data signal.
And for bidirectional call recording, AP module 904 transfers to digital audio mixing module 907 by descending digital audio and video signals by circuit 3, and transmitter 908 by circuit 5 by the upstream digital audio signal transmission to digital audio mixing module 907, in digital audio mixing module 907, upstream digital audio signal and descending digital audio and video signals can appear simultaneously, and carry out audio mixing by digital audio mixing module 907, concrete audio mixing process is: by 907 pairs of above-mentioned two kinds of digital audio and video signals of digital audio mixing module, decoded respectively, row decode signal and lower row decode signal in generation, and should go up row decode signal and lower row decode signal carries out recompile by digital audio mixing module 907, obtain digital audio signal, and this numeral audio signal is transmitted back to AP module 904, after processing via 904 processing of AP module, can obtain the bidirectional call recording file.Because normal talking has adopted circuit 1, circuit 2 and circuit 4, and Recording Process is carried out in AP module 904 and digital audio mixing module 907, makes both not there will be interactional phenomenon, improves the quality of conversation and recording.In addition, circuit 2, circuit 3 have adopted pcm bus or I2S bus, can certainly be other any bus or the circuits that can realize this transfer function.
More than be described with reference to the accompanying drawings technical scheme of the present invention, consider under existing technical scheme, while adopting the PS territory to carry out voice call, as while using the LTE module, can not realize bidirectional call recording in the LTE inside modules, therefore technical scheme of the present invention provides a kind of method and a kind of mobile terminal for realize bidirectional call recording at packet-switched domain, during voice call that can be under carrying out packet-switched domain, realize the bidirectional call recording of mobile terminal inside to the communication module voice signal, meet consumers' demand.
