Abstract

The embodiment of the invention discloses a method for establishing a call connection. The method includes the following steps: when the call connection with a calling terminal is interrupted, savinga phone number of the calling terminal, and switching to a frozen state, wherein the frozen state is that: when receiving that a number carried in a request for initiating the call connection is the phone number of the calling terminal, the call connection is prohibited from being initiated to the calling terminal according to the request for initiating the call connection; and when receiving thecall connection of the calling terminal in the frozen state, establishing the call connection with the calling terminal. The embodiment of the invention also discloses a called terminal and the calling terminal at the same time.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for establishing a call connection, a called terminal and a calling terminal. Background technique [0002] Nowadays, mobile phones have become the main way for people to communicate in daily life. However, the unstable state of the network often occurs, and the network is the basis for establishing calls. [0003] In the prior art, when people encounter a transient network failure during a call, the call will be interrupted abnormally. In this case, it often happens that both the calling user and the called user make calls to each other , thus causing the phone to fail to get through. Most likely, both parties will wait for the other party to call themselves at the same time, which leads to a long wait. Finally, the users of both parties cannot re-establish the connection in time after the call is interrupted abnormally. Contents of the invention [0004] In view of...
