Method for controlling call establishment

Abstract

The invention discloses a method for controlling call establishment. The method firstly sets group code information in the called terminal; sends the calling number and the corresponding group code information through short message, user-to-user signaling UUS, multimedia short message or Send it to the called terminal in the form of email; the called terminal judges whether the received group code information belongs to the group code set in step a, and if so, allows to establish a call between itself and the calling party corresponding to the calling number , otherwise, refuse to establish the call. The solution of the invention solves the problems caused by the various methods used by users to prevent telephone disturbances, such as the inability to connect important incoming calls, the need for additional processing costs, and the partial prevention of telephone disturbances. The called user in the solution of the present invention activates the group code call function when he does not want to be disturbed by frequent calls, which ensures that the called user avoids the disturbance of some unimportant incoming calls or harassing calls when he does not want to be disturbed, and at the same time ensures that the called user Never miss an important call.

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...

AI Technical Summary

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.
