Problems solved by technology

However, modern society has more and more requirements for communication, and there are more and more demands for three-party and more than three-party communication. Although the existing mobile phones support the call hold function, because the existing mobile phones only have one communication link module , or although there are mobile phones with multiple communication link modules on the existing market, their operators only support one voice link, which restricts them to only talk to one of them at any time, and cannot meet the requirements of communicating with the other two. and two or more users talking at the same time

[0003] Although there are mobile phones on the market that support multi-party calls, they must provide dedicated phone agents through mobile operators to achieve this function

In addition, the multi-party call reached through the phone agent of the mobile operator, such as a conference call, is expensive, takes a long time to connect to the phone, and must make a reservation for a conference call, and cannot conduct instant multi-party calls anytime and anywhere, which brings inconvenience to users
