PURPOSE: A call forwarding method of a wireless terminal is provided to add a software protocol for performing a new function to a switching system and a wireless terminal to update call information in real time, so that the wireless terminal can switch a call to the second wired terminal without a call disconnection if a user calls the wireless terminal with the first wired terminal, thereby reducing telephone charges. CONSTITUTION: A user dials a desired telephone number on a keypad of the first wired terminal, and a bell rings in a wireless terminal(S1). A switching system decides whether the telephone number is registered in a wired terminal call forwarding service(S2). If so, the switching system decides whether an automatic forwarding mode is set(S3). If so, the switching system modifies call information stored in a DB(S4). The second wired terminal is called(S5). The user makes a mutual call with the first and second wired terminals(S6).
