Title: Method for preferential incoming call prohibition in mobile phone
Inventor: KIM YEON HUI
IPC: H04M1/663
Filed: 2002-09-25
Abstract: PURPOSE: A method for selectively preventing an incoming call in a mobile communication terminal is provided to allow a user to receive only a desired call by discriminating calls by time zones and automatically rejecting an incoming call of a phone number registered as an inhibited number made for a specific time. CONSTITUTION: When a user sets an incoming call inhibited phone number registration mode by pressing a menu key(S201), a mobile communication terminal displays an image so that the user can input a desired incoming call inhibited phone number and incoming call inhibiting time for the phone number(S202). The mobile communication terminal registers the incoming call inhibited phone number and the incoming call inhibiting time as inputted by the user(S203). When a call is received from outside(S204), the mobile communication terminal checks whether an incoming call inhibiting mode has been set by the user(S205). If it is in the incoming call inhibiting mode, the mobile communication terminal checks a phone number of the caller and also checks whether the caller's phone number is an incoming call inhibited phone number(S207). If the caller's phone number is the incoming call inhibited phone number, the mobile communication terminal checks whether it is incoming call inhibiting time with respect to the incoming call inhibited phone number(S209). If it is the incoming call inhibiting time, the mobile communication terminal does not ring a phone bell and refuses to receive it(S210).
