Abstract

The invention discloses a voice call method, a voice call system and a communication terminal. The voice call method includes the steps of building a negotiation text message communication protocol between a calling terminal and a called terminal to keep consistent in understanding a negotiation text message; after the calling terminal receives a voice call instruction of the called terminal, sending a first negotiation text message to the called terminal; and according to response of the called terminal to the first negotiation text message, executing corresponding operations on the calling terminal. Service negotiation is achieved by means of the negotiation text message before voice call is initiated, so that the calling party can learn statues of the called party in time and then does corresponding operations according to the information. Further, the users can do the corresponding operations such as initiating the voice call and canceling the voice call so as to avoid being disturbed by the voice call in the circumstance with inconvenience to answer the call; furthermore, the called party can initiate the voice call actively in a circumstance meeting preset conditions and realize calling free of charge; thus, resources are saved, calling cost is saved, and users' experiences are improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a voice calling method, system and communication terminal. Background technique [0002] When two communication terminals establish a voice service connection, the general method is to initiate a voice call through the calling party, and the called party answers or rejects the voice call.

[0002] When two communication terminals establish a voice service connection, the general method is to initiate a voice call through the calling party, and the called party answers or rejects the voice call. The defect of this method is that the calling party often does not know the status information of the called party , if the called party is inconvenient to make a voice call in a conference or for other reasons, the voice call initiated by the calling party will disturb the called party

In another case, the called party is more suitable to initiate a voice call, such as the calling party is free of charge, etc., the traditional call method cannot adjust the call according to this situation, resulting in waste of resources

Therefore, the existing voice call method has poor user experience
