Embodiment one
Fig. 1 is a kind of flow chart of the method for switching secret telephony that the embodiment of the present invention one provides.The method of the present embodiment can be performed by the device of switching secret telephony, and described device can be realized by way of software and/or hardware, and can typically be integrated in call terminal.As shown in figure 1, the method for the switching secret telephony that the present embodiment provides specifically includes：
S110, receive the triggering command that secret telephony is switched to from common call.
With the development of the various mobile communication technologies in modern times, user can be linked up and exchanged by call terminals such as mobile phone, tablet personal computers.
Existing GSM has many kinds, for example, CDMA (Code Division Multiple Access, CDMA) and global system for mobile communications (Global System for Mobile Communication, GSM).GSM provides the user information access and forwarding services, and ensures the unimpeded communication of user.Such as, the principle of cdma system is to be based on spread spectrum, and will need transmission has certain signal bandwidth information data, is modulated with high speed pseudo noise code of the bandwidth much larger than signal bandwidth, the bandwidth of former data-signal is expanded, then it is carrier-modulated and send.Spread spectrum clear advantage is that its antijamming capability is especially strong, in addition, the CDMA great disguise of signal of communication, due to information signal, frequency spectrum is greatly expanded after band spectrum modulation, substantially reduce the power spectral density of signal, the signal spectrum density ratio receiver noise that receiving terminal receives is low, i.e. signal is submerged in noise completely, reception so to other same frequency range radio station will not form interference, signal is also just not easy to be found, further detect that signal is just more difficult to, so there is very high disguise.Although CDMA confidentiality is fine, network attack person, network operator etc. are also the Content of Communication that can obtain user, the problem of being likely to result in privacy leakage.So secret telephony can be established to protect the privacy of both call sides.This programme can be applicable on the secret telephony of cdma system, can also equally apply in other systems, the embodiment of the present invention is not construed as limiting to this.
For existing manual switching secret telephony technology, in addition to the drawbacks of oral negotiation easily loses the crypticity of secret telephony, Consumer's Experience is also poor.If user have forgotten oral negotiation before secret telephony is entered, and click directly on secret telephony button, then other side is simultaneously ignorant, will result in other side and does not go call caused by clicking on speech scrambling button to fail.Also a kind of special circumstances, user accidentally trigger secret telephony button in common call, again result in the generation of call drop.
The embodiment of the present invention provides a kind of method of switching secret telephony, firstly, it is necessary to receive the triggering command that secret telephony is switched to from common call.The triggering mode of the instruction can have many kinds, can be to click on secret telephony button, it can also be to slide a kind of gesture on the touchscreen on the call terminal with touch-screen, equally can also be to press finger to carry out fingerprint recognition on the call terminal with fingerprint identification function.Other, or physical marks identification etc..Fingerprint recognition and physical marks identification etc. also play the effect of protection privacy to a certain extent.
What deserves to be explained is the method for the switching secret telephony that this programme provides can apply to the situation that user triggers switching secret telephony, the situation of external condition triggering switching secret telephony can also be applied to.
S120, secret telephony request is sent to distant terminal, for establishing secret telephony, the subsidiary audio prompt information of secret telephony request.
The subsidiary audio prompt information of secret telephony request, the audio prompt information is to be built in an audio prompt information of local terminal in advance.After user is triggered by certain mode is switched to the instruction of secret telephony from common call, local terminal receives the triggering command that secret telephony is switched to from common call, it can be obtained to being pre-stored in local audio prompt information, the audio prompt information can be a voice for prompting to be switched to secret telephony.For example, the audio prompt information is " please be switched to secret telephony state " or " other side's request enters secret telephony state ".The audio prompt information is preferably clearly brief speech data.
After local terminal obtains audio prompt information, the audio-frequency information is sent to distant terminal by the voice channel commonly conversed.After local terminal has sent the audio prompt information, the secret telephony application stage is advanced into certainly.The process that local terminal sends audio prompt information is voluntarily completed by local terminal, it is not necessary to which user carries out oral negotiation or informed, ensure that the confidentiality that encrypted word is established.Exemplary, when local user triggers the function of switching secret telephony, local terminal sends " please be switched to secret telephony state " to distant terminal automatically, peer user receives to it, when peer user hears this voice by normal speech passage, then the function of the switching secret telephony of distant terminal is can trigger in special time.This special time is that peer user triggers the effective time of this function after the function that switching secret telephony is triggered in local terminal.For example, it can be 10 seconds.In this special time, the printed words of " during encrypted word is established " can be shown on terminal display screen, equally have suggesting effect to user.
What deserves to be explained is audio prompt information is transmitted by the voice channel commonly conversed, i.e., it is transmitted by circuit domain, rather than is transmitted by modes such as procotol (Internet Protocol, IP) packets.If the audio prompt information is transmitted by IP packets, then need to be compressed data coding, encryption and packing, sent afterwards in the form of IP packets to distant terminal, distant terminal receives this IP packet, it is decrypted and decoded, then writes data into loudspeaker.This process has one section of time delay.So audio prompt information is transmitted by this programme by circuit domain, delay problem is avoided, accelerates the foundation of secret telephony.
S130, receive the distant terminal return build the information of vertical secret telephony really when, be switched to secret telephony pattern.
After distant terminal receives secret telephony request, peer user triggering is switched to the instruction of secret telephony from common call.When distant terminal, which receives, is switched to the triggering command of secret telephony from common call, the information for confirming to establish secret telephony is returned to local terminal, and local terminal receives this and confirmed after establishing the information of secret telephony, is switched to secret telephony pattern.
Art scheme had both gone for end-to-end (D2D) communication, can also realize this secret telephony by the webserver (such as communication network), the embodiment of the present invention is not construed as limiting to this.
