Abstract

The invention relates to a multi-party call method and system, a conference server and electronic equipment, and relates to the technical field of communication. The method comprises the steps that a conference server receives a multi-party call access request sent by each terminal, the multi-party call access request sent by each terminal comprises a guide identifier of the terminal, and the guide identifier is distributed by the terminal and a guide server in a general guide architecture GBA authentication process; the conference server obtains the key of each terminal from the guide server according to the guide identifier of each terminal; the conference server receives call speaking data which are respectively sent by each terminal and are encrypted by adopting own secret keys; for each terminal, the conference server decrypts the encrypted call speaking data of the terminal according to the key of the terminal; and for each terminal, the conference server encrypts the decrypted call speaking data of the terminal by using the secret keys of the other terminals, and then sends the encrypted call speaking data to the other terminals.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a method, system, conference server and electronic equipment for multi-party calls. Background technique [0002] VoLTE (Voice over Long-Term Evolution, voice based on long-term evolution) is an end-to-end voice solution based on all IP conditions on the 4G network. Based on the IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) network, voice services can be used as Data streams are transmitted in the LTE network. [0003] Multi-party calls can be implemented by multiple terminals through VoLTE technology. However, the VoLTE voice data of the terminal is easy to be eavesdropped or tampered with during transmission, thus threatening user privacy. Contents of the invention [0004] A technical problem to be solved by the present disclosure is: how to improve the security of the multi-party call process. [0005] According to some embodiments of the pre...
