Inventor: LEE HYEON BOK
IPC: H04M1/54
Filed: 2000-12-29
Abstract: PURPOSE: A selection call method in a wireless telephone set is provided to call only all specific hand set or base set selectively, so that the effect like plural telephone numbers is obtained by using one telephone number, thereby enhancing the use efficiency. CONSTITUTION: A user inputs a telephone number and other information of an another person by using a memory function of a base set, inputs a handset for receiving corresponding to the telephone number and selects a selection call function of the telephone set. The user also sets the selection call function to the handset provided at the one's own room. When calling a caller from the exterior, the base set discriminates whether the selection call function is set at present. If the selection call function is set, the base set compares the inputted caller ID with the stored telephone number. If the inputted caller ID is the set telephone number, the caller ID and a ring signal are transmitted to all handsets. When the telephone number corresponding to the caller ID is designated as the selection call function, the handset generates a ring signal.
