Encrypted call control method and terminal

Abstract

The invention provides an encrypted call control method and a terminal. The encrypted call control method comprises the steps that an encrypted call control command is received in the encrypted call process; and a corresponding encrypted call processing request is sent to a receiving party terminal of an encrypted call according to the encrypted call control command, so that the receiving party terminal can determine whether to decrypt follow-up speech streams or not according to the encrypted call processing request. According to the technical scheme, due to the fact that the condition that the receiving party terminal falsely decrypts the speech streams from the Internet can be avoided in the encrypted call keeping process, noise generated by false decryption is avoided, and the user experience obtained when call keeping is conducted in the encrypted call is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to an encrypted call control method and a terminal. Background technique [0002] Currently, CS domain (Circuit Switched Domain) voice calls based on GSM (Global System for Mobile Communications) and WCDMA (Wideband Code Multiple Access), and PS (Packet Switched) domain voice calls based on Volte (Wideband Voice Function) support single On hold, that is, during a voice call, the original call is temporarily suspended. During the suspension period, the original call is not hung up. When the user needs to resume the original call, the user can choose to activate the original call, and the original call will continue. [0003] However, due to the actual needs of users, encrypted calls are often required. Although operators have launched end-to-end encrypted communications in the CS domain, they can provide end-to-end voice encryption for users. For example, China Unicom has ...

[0004] However, the call hold function is prohibited in these encrypted communication schemes. Specifically, in an encrypted call system, the source voice needs to be encrypted on the source terminal before being transmitted to the network. After the encrypted voice reaches the destination terminal, it needs to be encrypted. The voice can only be restored by decryption. If the existing encrypted communication scheme is applied, the destination terminal often receives voice streams such as ringtones from the network during the hold process of the encrypted call, and the encrypted call also decrypts these voice streams by default. , however, these voice streams are not encrypted. In this way, the unencrypted voice stream becomes noise due to the decryption operation. In the end, what the user of the destination terminal hears when the source terminal is on hold is all Noise, bringing bad experience to users
