Abstract

A system for refusing to receive an individual call by using a mobile communication network and a method thereof are provided to intercept an individual incoming call having an unwanted phone number with an abnormal telephone exchange number or regardless of kinds of switching systems of other communication service providers. A method for refusing to receive an individual call by using a mobile communication network comprises the following several steps. A user subscribes for an individual incoming call refusing server, and registers phone numbers, from which the subscriber wants to refuse to receive a call, at an incoming call refusing list(S510). A calling side wired phone set transmits a call connection request signal, including a call sending number with an abnormal phone number system, to an HLR(Home Location Register) through a gateway HLR, and the HLR checks whether an originating number and a destination number are registered at the incoming call refusing list by referring to the originating number and the destination number included in the call connection request signal(S520). In case that the destination number is registered and the origination number with an abnormal number system is not registered, the HLR notifies an automatic response service server that the originating number is abnormal(S530). The automatic response service server transmits a preset recorded guide message to the calling side wired phone set(S540). In case that an answer agreeing with the recorded guide message is transmitted to the automatic response service server via the HLR, the automatic response server allows the calling side wired phone set to make a call connection to a receipt side terminal via an MSC(Mobile Switching Center)(S550).
