ASYNCHRONOUS IMT-2000 SYSTEM HAVING A NICKNAME TRANSMISSION FUNCTION AND A NICKNAME SERVICE METHOD, ESPECIALLY CONCERNED WITH TRANSMITTING A NICKNAME, APPOINTED BY A CALLER, TO A CALLED TERMINAL IN CASE THAT THE CALLER ATTEMPTS A CALL

摘要

PURPOSE: An asynchronous IMT-2000 system having a nickname transmission function and a nickname service method are provided to present a caller nickname service so that a called subscriber can identify a caller through the caller's nickname more easily. CONSTITUTION: An asynchronous IMT-2000 network comprises a nickname service server(100). The nickname service server(100) requests an asynchronous IMT-2000 network subscriber, who has registered for a nickname service in an HLR(50), to appoint nicknames. If the subscriber attempts a call after appointing nicknames, a called-side HLR requests the nickname service server(100) to transmit a nickname. The nickname service server(100), in response to the called-side's request, searches for a nickname appointed to the associated called subscriber and transmits the searched nickname the called-side HLR.
