Abstract

PURPOSE: A short message providing method of a mobile communication system in automatic connection or call forwarding is provided to allow a user to receive a short message through a different terminal when a mobile communication terminal is not available for use. CONSTITUTION: An MS(Mobile Station) sets automatic connection or call forwarding service(S10). An arbitrary originating MS sends a short message to the destination MS which has subscribed for the automatic connection or the call forwarding service(S20). An HLR(Home Location Register) receives the automatic connection or call forwarding information, changes, stores and manages the automatic connection or call forwarding information, and provides the automatic connection or call forwarding information of the destination MS to an SMC(Short Message Center)(S30). The SMC changes an incoming call of the short message to the automatic connection or to a call-forwarded terminal and transmits corresponding information to a BSC(Base Station Controller)(S40). The BSC automatically connects the incoming call or directly transfers a short message to the call-forwarded terminal(S50).
