Problems solved by technology

[0003] However, on the one hand, due to the existence of the vocoder lossy compression coding mechanism in the voice communication link, the traditional encryption technology is not suitable for the voice service channel of circuit switching; on the other hand, due to the VAD (Voice Activity Detection, voice activity detection) The existence of the mechanism, if the encrypted speech presents random characteristics, the speech will be filtered out as noise to save network bandwidth

Abstract

The invention relates to a mobile communication circuit domain voice processing apparatus, method and system. The apparatus includes a Bluetooth HCI module. The Bluetooth HCI module is connected to a processor, enables wireless connections to be configured in a mobile terminal, and receives unencrypted mobile communication circuit domain voice of the mobile terminal or receives mobile communication circuit domain voice decrypts by the processor and sends the mobile communication circuit domain voice to the mobile terminal. The processor, connected to a mobile network, receives unencrypted mobile communication circuit domain voice of the Bluetooth HCI module, encrypts the mobile communication circuit domain voice in an encryption mode through a penetrable sounder and sends the encrypted mobile communication circuit domain voice to the mobile network, or receives mobile communication circuit domain voice encrypted by the mobile network, decrypts the mobile communication circuit domain voice and then sends the mobile communication circuit domain voice to the Bluetooth HCI module. An end-to-end encryption method that can withstand a lossy compression coding mechanism and a VAD (Voice Activity Detection) mechanism is adopted for encryption. In this way, voice is prevented from leaking during transmission, and the demand of encryption of communication circuit domain voice on a conventional communication channel is met.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a mobile communication circuit domain voice processing device and method utilizing short-distance wireless technology communication and data encryption. Background technique [0002] The existing security mechanism of the mobile communication system is designed on the assumption that the mobile core network is safe and reliable. Therefore, the mobile system only provides encryption for the wireless channel without considering the security measures of the core network, and the voice is transmitted on the ground link in a clear way, which provides the possibility of wiretapping, making personal privacy, business information and even state secrets It has been seriously threatened, causing huge risks, hidden dangers and losses to users and various organizations. In addition, the encryption mechanism of the wireless channel is optional for the operator. Even if wirele...
