A method for call establishment control

Abstract

A method for controlling the call set-up is provided. The method comprises: firstly setting a group code data at a called terminal, sending a calling number and corresponding group code data to the called terminal; the called terminal judges whether the received group code data is the one set in the previous step a, if yes, allowing the set-up of the call between the called terminal and the calling number, otherwise refusing the set-up of the call. The inventive proposal solves the problems of failure to access to the important incoming call, extra handling expense and poor effect in preventing disturbing calls, caused by preventing disturbing calls. In the inventive proposal, the group code call function is started when the called party is unwilling to be disturbed, so as to prevent the disturbance of unimportant incoming calls or annoying calls when the called party is unwilling to be disturbed, and simultaneously ensure the called party not to miss the important incoming calls.

Description

technical field [0001] The present invention relates to the technical field of communication, more specifically to a method for controlling call establishment. Background technique [0002] With the popularization of terminal devices such as fixed telephones and mobile phones, the terminal devices bring great convenience to people's work and life, and people can use these terminal devices to communicate with the outside world at any time. However, these terminal devices also bring certain troubles to users. For example, users hope that they will not be disturbed by unimportant incoming calls at night or during other rest periods, but at the same time they will not lose important incoming calls. But in fact, there are often some irrelevant calls during this period, and some are even harassing calls. [0003] In order to avoid being disturbed by incoming calls, the user can turn off the terminal device, and turn on the terminal device again when needed. For this solution of...

Problems solved by technology

For this solution of closing the terminal equipment, since the terminal equipment includes fixed terminals and mobile terminals, mobile terminals are easier to shut down, and for fixed phones, if you want to shut down, you can only cut off the telephone line at present, which is very important for users. very inconvenient

Regardless of whether it is a mobile terminal or a fixed terminal, turning off the terminal device will bring other problems: once the terminal device is turned off, the user will not be able to answer any calls. In this way, even if others have very important things, they will not be able to communicate with the user through the terminal device. connect

In addition, the maintenance of black and white lists is relatively cumbersome.
