技术领域technical field

本发明涉及一种移动通信终端的通话录音方法，尤其涉及一种适用于多模移动通信手机的通话录音方法。The invention relates to a call recording method of a mobile communication terminal, in particular to a call recording method suitable for a multi-mode mobile communication mobile phone.

背景技术Background technique

随着科学技术的发展，通信科技日新月异，移动通信手机已被人们广泛应用于日常生活和学习中，人们通过移动通信手机和网络通话或互发短信息，其不但大大拉近了人们彼此之间的距离，还给人们的联系和信息交流带来了极大的便利。With the development of science and technology, communication technology is changing with each passing day. Mobile communication phones have been widely used in people's daily life and study. The distance also brings great convenience to people's contact and information exchange.

目前主要有两个移动通信网络，即GSM和CDMA。然而，因两个网络的业务，资费，覆盖等不同，各有优势，用户可能需要同时拥有两个网络的服务，一般情况下，要实现使用两个网络，即需要使用两个移动终端，这在携带和使用方面都极其不便，因此希望使用一个移动终端，就可以实现使用两个网络。There are currently two main mobile communication networks, namely GSM and CDMA. However, due to the different services, charges, and coverage of the two networks, each has its own advantages, and users may need to have the services of the two networks at the same time. In general, to realize the use of two networks, that is, two mobile terminals are required. It is extremely inconvenient to carry and use, so if you want to use one mobile terminal, you can use two networks.

现有的双模移动终端(如中国第200510024476.X号专利申请所揭示的一种双模/多模便携装置及其智能切换方法)可实现使用两个网络的服务。目前移动终端已从单一的通信工具向多功能的个人终端发展，通话录音就是手机上不断丰富和完善的功能之一，然而，现有的通话录音方案往往是针对通信终端的一种特定通话网络，提供简单的固定的通话录音功能，常见的录音格式主要有amr，wav等，也有的通过外接mp3录音装置实现通话录音功能。通话录音的业务需求有主动通话录音和自动应答留言录音两种，实现这两种需求的方案中录音装置的处理都是固定的，都没有考虑针对CDMA网或GSM网的业务需求和通信特点对录音进行分别处理，不能根据CDMA网或GSM网通信的特点对录音进行分别处理，导致移动终端系统资源利用率低、录音质量不高。Existing dual-mode mobile terminals (such as a dual-mode/multi-mode portable device and its intelligent switching method disclosed in Chinese Patent Application No. 200510024476.X) can implement services using two networks. At present, mobile terminals have developed from a single communication tool to a multi-functional personal terminal. Call recording is one of the functions that are constantly enriched and improved on mobile phones. However, the existing call recording solutions are often aimed at a specific call network for communication terminals. , provide simple and fixed call recording function, the common recording formats mainly include amr, wav, etc., and some call recording functions are realized through an external mp3 recording device. The business requirements for call recording include active call recording and automatic answering message recording. The processing of the recording device is fixed in the solution to realize these two requirements, and the business requirements and communication characteristics of the CDMA network or GSM network are not considered. The recordings are processed separately, and the recordings cannot be processed separately according to the characteristics of the CDMA network or GSM network communication, resulting in low resource utilization of the mobile terminal system and low recording quality.

请一并参阅图2，因本实施例的双模移动手机的CDMA网络和GSM网络的语音信道存在一定差异，为达到录音质量与资源使用效率的最佳平衡，本发明移动通信终端的通话录音方法对两种网络的通话录音分别采用不同的录音处理。对于语音信道较好的通话网络，仍然可以采用常见的8K采样录音，编码和存储格式采用AMR格式，优点在于占用的存储空间很少；对于语音信道稍差的通话网络则可以提高采样率，以减小较高频率的干扰信号对语音信号产生影响，编码采用ADPCM或MP3格式等，虽然占用存储空间多一点，但能保证通话录音的质量；同时，根据两种网络语音信道的差异，分别调节对应的通话录音增益，使两种通话录音都能保持较好质量。具体步骤如下所述：Please also refer to Fig. 2, because there is certain difference in the voice channel of the CDMA network of the dual-mode mobile handset of the present embodiment and the GSM network, in order to reach the optimum balance of recording quality and resource utilization efficiency, the call recording of the mobile communication terminal of the present invention Methods Different recording processes were adopted for the call recordings of the two networks. For a communication network with a better voice channel, the common 8K sampling recording can still be used, and the encoding and storage format adopts the AMR format, which has the advantage of occupying less storage space; Reduce the impact of higher frequency interference signals on the voice signal. The encoding adopts ADPCM or MP3 format, etc. Although it takes up a little more storage space, it can ensure the quality of call recording; at the same time, according to the difference between the two network voice channels, adjust respectively The corresponding call recording gain keeps the quality of both call recordings good. The specific steps are as follows:

201.通话进行中；201. The call is in progress;

202.系统判断当前通话发生所属的通信网络；202. The system judges the communication network to which the current call belongs;

203.系统判断当前通话所属通信网络的语音信道是否理想，若是则执行步骤205，若否则执行步骤204；203. The system judges whether the voice channel of the communication network to which the current call belongs is ideal, if so, executestep 205, otherwise executestep 204;

204.调节通话录音增益，采用较高的录音采样率；204. Adjust the call recording gain and adopt a higher recording sampling rate;

205.录音。205. Recording.

请一并参阅图3，可以理解，当用户使用本实施例双模移动手机通话时，可主动控制通话录音，并可选择性的进行单向录音和双向录音，其中单向录音是指通话状态下只录入接听方或来电方的声音，双向录音是指通话状态下对接听方和来电方的声音同时进行录入。Please also refer to Fig. 3, it can be understood that when the user uses the dual-mode mobile phone of this embodiment to talk, he can actively control the call recording, and can selectively perform one-way recording and two-way recording, wherein the one-way recording refers to the call state In this mode, only the voice of the receiving party or the calling party is recorded. Two-way recording means that the voices of the receiving party and the calling party are recorded simultaneously in the call state.

单向录音的步骤如下所述：通话已经建立后，用户主动启动本装置进行通话录音。若只录入接听方声音则中央处理器60控制语音芯片及驱动电路20，只将音频输入装置50的音频信号作为音源；若只录入来电方的声音则只将通信部件10的话音输出作为音源，中央处理器60先与通信部件10进行交互，明确当前的通话网络，如网络语音信道不理想，则调节语音芯片20中的录音增益，同时采用较高采样率进行音频录入，否则在正常的录音增益下采用8K采样率进行音频录入。语音芯片及驱动电路20将采样到的语音数据拷入内存30，由中央处理器60在较高采样率下进行ADPCM或MP3编码，8K采样率下进行AMR编码，最后在中央处理器60的控制下将编码好的数据存储至存储介质40上。存储时根据音源来自通话网络的不同在存储位置、文件名等存储方式上加以区别，以满足用户在双网使用下的业务需要。可以理解，当单向录入接听方的声音时，为减小环境的高频信号对语音信号的影响，在语音芯片20中采用较高采样率进行音频录入，采样得到的语音数据拷入内存30进行ADPCM或MP3编码，编码后的数据根据通话网络的不同在存储位置、文件名等存储方式上加以区别存入存储介质40，如中央处理器60在存储介质40上分别创建对应CDMA网络和GSM网络的主动通话录音的存储目录，以满足用户在双网使用下的业务需要(请一并参阅图5)。The steps of the one-way recording are as follows: After the call has been established, the user actively activates the device to record the call. If only recording the voice of the receiving party, then thecentral processing unit 60 controls the voice chip and thedrive circuit 20, only the audio signal of theaudio input device 50 is used as the sound source; Thecentral processing unit 60 first interacts with thecommunication unit 10 to clarify the current call network. If the network voice channel is not ideal, the recording gain in thevoice chip 20 is adjusted, and a higher sampling rate is used for audio recording. Gain uses 8K sampling rate for audio recording. Voice chip anddriving circuit 20 copy the sampled voice data intointernal memory 30, perform ADPCM or MP3 encoding at a higher sampling rate by thecentral processing unit 60, perform AMR encoding at a sampling rate of 8K, and finally perform ADPCM encoding under the control of thecentral processing unit 60. Next, store the coded data on thestorage medium 40. When storing, the storage location, file name and other storage methods are distinguished according to the difference of the audio source from the call network, so as to meet the business needs of users under dual-network use. It can be understood that when the voice of the receiving party is recorded in one direction, in order to reduce the impact of the high-frequency signal of the environment on the voice signal, a higher sampling rate is used in thevoice chip 20 to record the audio, and the voice data obtained by sampling is copied into theinternal memory 30 Carry out ADPCM or MP3 encoding, the data after the encoding is stored in thestorage medium 40 according to the difference in storage location, file name and other storage methods according to the difference of the communication network, such as thecentral processing unit 60 respectively creates the corresponding CDMA network and GSM network on thestorage medium 40 The storage directory of the active call recording of the network is to meet the service needs of the user under the use of the dual network (please also refer to FIG. 5 ).

双向录音的步骤如下所述：通话已经建立后，用户主动启动本装置进行通话录音。中央处理器60控制语音芯片及驱动电路20，将音频输入装置50的音频信号和通信部件10的话音输出同时作为音源，其分别对应接听方和来电方的声音。中央处理器60先与通信部件10进行交互，明确当前的通话网络，如网络语音信道不理想，则调节语音芯片20中的录音增益，同时采用较高采样率进行音频录入，否则在正常的录音增益下采用8K采样率进行音频录入。语音芯片及驱动电路20将采样到的语音数据拷入内存30，由中央处理器60在较高采样率下进行ADPCM或MP3编码，8K采样率下进行AMR编码，最后在中央处理器60的控制下将编码好的数据存储至存储介质40上。存储时根据音源来自通话网络的不同在存储位置、文件名等存储方式上加以区别，以满足用户在双网使用下的业务需要(请一并参阅图5)。可以理解，因双向录音时音源包括接听方和来电方的声音两部分，为了在提高来电方的声音增益的同时不使接听方声音的增益出现明显改变，应同时适当降低音频输入装置的增益。The steps of the two-way recording are as follows: After the call has been established, the user actively activates the device to record the call. Thecentral processing unit 60 controls the voice chip and the drivingcircuit 20, and simultaneously uses the audio signal of theaudio input device 50 and the voice output of thecommunication unit 10 as sound sources, which respectively correspond to the sounds of the receiving party and the calling party. Thecentral processing unit 60 first interacts with thecommunication unit 10 to clarify the current call network. If the network voice channel is not ideal, the recording gain in thevoice chip 20 is adjusted, and a higher sampling rate is used for audio recording. Gain uses 8K sampling rate for audio recording. Voice chip and drivingcircuit 20 copy the sampled voice data intointernal memory 30, perform ADPCM or MP3 encoding at a higher sampling rate by thecentral processing unit 60, perform AMR encoding at a sampling rate of 8K, and finally perform ADPCM encoding under the control of thecentral processing unit 60. Next, store the coded data on thestorage medium 40. During storage, the storage location, file name and other storage methods are differentiated according to the source of the sound from the communication network, so as to meet the user's business needs under dual-network use (please also refer to Figure 5). It can be understood that since the audio source includes the voice of the receiving party and the voice of the calling party during two-way recording, in order to increase the gain of the voice of the calling party without significantly changing the gain of the voice of the receiving party, the gain of the audio input device should be appropriately reduced at the same time.

请一并参阅图4，可以理解，当用户因忘记携带或工作繁忙无法接听本实施例双模移动手机的来电时，可采用自动应答，并对自动应答留言进行录音。录音步骤如下：用户根据CDMA网络和GSM网络的业务需要分别设定是否需要启动自动应答留言功能和启动该功能需要等待的延时。通信部件10在有来电接入时通知中央处理器60，开始计时。如用户在设定的延时内没有接听来电，则中央处理器60自动对来电进行接听，并根据来电的通话网络在存储介质40上选择用户事先为该网络定制的应答语音数据，将之拷贝至内存30，然后根据其编码格式由中央处理器60对其进行解码成原始的PCM语音数据送至语音芯片20，语音芯片20将播放的语音信号直接送至通话部件10作为通话的接听方语音输入，同时屏蔽音频输入装置50的输入，在语音信号播放完毕时定义一个标识，如某个特定的声音，然后中央处理器60控制语音芯片进入对来电进行单向通话录音的状态，即屏蔽音频输入装置50的输入，只将通信部件10的话音输出作为音源进行录音。根据来电网络信道质量的差异中央处理器60控制语音芯片20的录音增益和在录音时采用的采样率。对语音芯片20录入的语音数据拷入内存30，采样率为8K的采用AMR编码，采样率高于8K的采用ADPCM或MP3编码，最后将编码后的数据存入存储介质40，根据在存储位置、文件名等存储方式上的区别对与该语音数据对应的通话网络、来电信息、来电时间等加以标识，以满足用户在双网使用下的业务需要(请一并参阅图5)。Please also refer to FIG. 4 . It can be understood that when the user forgets to carry it or is busy with work and cannot answer the incoming call of the dual-mode mobile phone in this embodiment, automatic answering can be used, and the automatic answering message is recorded. The recording steps are as follows: the user sets whether to start the automatic answering message function and the time delay required to start the function according to the business needs of the CDMA network and the GSM network. Thecommunication part 10 notifies thecentral processing unit 60 when there is an incoming call, and starts timing. If the user does not answer the incoming call within the set time delay, thecentral processing unit 60 automatically answers the incoming call, and selects the answering voice data customized for the network in advance by the user on thestorage medium 40 according to the call network of the incoming call, and copies it to theinternal memory 30, then it is decoded into original PCM voice data by thecentral processing unit 60 according to its encoding format and sent to thevoice chip 20, and thevoice chip 20 directly sends the voice signal played to the talkingpart 10 as the receiver voice of the conversation Input, shield the input ofaudio input device 50 simultaneously, define a sign when voice signal is played, as a certain specific sound, thencentral processing unit 60 controls voice chip to enter the state that incoming call is carried out one-way conversation recording, promptly shields audio The input of theinput device 50 is recorded only with the voice output of thecommunication unit 10 as a sound source. TheCPU 60 controls the recording gain of thevoice chip 20 and the sampling rate adopted during recording according to the difference of the network channel quality of the incoming call. The voice data ofvoice chip 20 input is copied intomemory 30, the sampling rate of 8K adopts AMR encoding, the sampling rate is higher than 8K and adopts ADPCM or MP3 encoding, and finally the data after encoding is stored instorage medium 40, according to the storage location , file name and other storage methods to identify the call network corresponding to the voice data, call information, call time, etc., to meet the user's business needs under dual-network use (please also refer to Figure 5).
