Problems solved by technology

At present, the industry implements LTE voice services in the following ways: CSFB (Circuit Switching Fall-Back, circuit switching domain voice fall-back), SR-VCC (Single Radio Voice Call Continuity, monophonic voice call continuity), VOLGA (Voice Over LTE via Generic Access, voice operation through ordinary access to LTE), etc., but these methods still use the 3G core network to realize the transmission of voice data in essence. The voice communication can only be realized based on a certain data channel. How to pass the LTE module Realizing two-way call recording is still an unresolved problem

Abstract

The invention provides a method of realizing bidirectional call recording in a packet switched domain. The method comprises the following steps: 102, carrying sound mixing on an uplink audio signal and a downlink audio signal in a call process to generate a mixed audio signal; and 104, generating a call recording file by utilizing the mixed audio signal. Correspondingly, the invention also provides a mobile terminal. According to the technical scheme of the invention, when a voice call is carried out in the packet switched domain, bidirectional call recording can be carried out on voice signals of a communication module inside the mobile terminal, thereby meeting the requirement of a user.

Description

technical field [0001] The invention relates to call recording technology, in particular to a method and a mobile terminal for realizing two-way call recording in a packet switching domain. Background technique [0002] At present, under the 2G / 3G network, the voice service is mainly implemented in the CS (Circuit-Switched Domain, Circuit-Switched Domain) domain, while the LTE (Long Term Evolution, Long Term Evolution) is based on the packet-switched Domain, packet switching domain), so to implement voice services on LTE terminals, other channels must be used. At present, the industry implements LTE voice services in CSFB (Circuit Switching Fall-Back, circuit switching domain voice fall-back), SR-VCC (Single Radio Voice Call Continuity, monophonic voice call continuity), VOLGA (Voice Over LTE via Generic Access, voice operation through ordinary access to LTE), etc., but these methods still use the 3G core network to realize the transmission of voice data in essence. The voi...
