Abstract

The present invention discloses a method for controlling a process of establishing a call, comprising: setting group codes in a called terminal; sending a calling number and a corresponding group code to the called terminal; the called terminal determining whether the received group code is one of the group codes set in the called terminal, if the received group code is one of the group codes set in the called terminal, allowing a call to be established between the calling terminal corresponding to the calling number and the called terminal, otherwise, refusing the call. According to one aspect of the invention, the called user enables a function of group code call when he does not want to be disturbed by frequent calls. So the called user will not be disturbed by unimportant calls or harassing calls while simultaneously the called user will not miss any important call.
