Method for avoiding malicious calling

Abstract

The method includes following steps: (1) user activates service of 'stopping malicious call'; (2) user adds phone number list of malicious call; (3) validating phone number of incoming call: if phone number of incoming call is a malicious call, the incoming call is ended, otherwise normal call flow is initiated. The invention possesses features of simple workflow, realizable by using digital stored-program control exchange and software, without need of additional hardware resources, extending service area of stored-program control exchange.

Description

technical field [0001] The invention relates to a digital program-controlled exchange in a telecommunication network, in particular to a call control method in a program-controlled exchange. Background technique [0002] The current digital program-controlled exchange can provide supplementary services for malicious calls according to user applications.
