Description

Method and device for realizing multi-party call and multi-pass terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for implementing a multi-party call, and a multi-pass terminal.

Background

With the continuous improvement of the mobile network bandwidth and the optimization of the mobile device performance, the requirements of the user on the services provided by the mobile terminal are gradually increased. At present, mobile terminal services are becoming more and more diversified from traditional two-person conversation, and services such as video conversation, call forwarding, multi-party conversation and the like are added. In the existing method for a host to implement a multi-party Call, a host implements audio mixing of the multi-party Call at the host, and when a network signal is poor and cannot provide a normal Voice over LTE (Voice over LTE, LTE-based network audio and video Call) Call service, a host terminal initiates SRVCC (Single Radio Voice Call Continuity) to switch to another network. After SRVCC switching, the multi-party call terminal only leaves two calls, the nearest call in the activated state before switching is in the activated state after switching, the second nearest call in the activated state before switching is in the holding state after switching, and the rest calls are hung up.

In the process of implementing the invention, the inventor finds that at least the following technical problems exist in the prior art:

the existing multi-party call technology of terminal sound mixing can not keep multi-party call after SRVCC is carried out due to poor network signal.
