APPARATUS AND METHOD FOR REDUCING DELAY OF SUBSCRIBER AUTHENTICATION

摘要

PURPOSE: An apparatus and a method for reducing delay of subscriber authentication are provided to reduce the delay in a subscriber authentication procedure required during the switching operation between an HSDPA communication service and a Wibro communication service. CONSTITUTION: An HSDPA(High Speed Downlink Packet Access) communication modem(120) receives an HSDPA subscriber authentication information from a subscriber authentication information module, and performs an authentication process with an HSDPA authentication service to provide a communication service. If a Wibro subscriber authentication request is received, a control unit(130) requests Wibro subscriber authentication information from the HSDPA communication modem, and provides the Wibro subscriber authentication information to a Wibro broadband(140).
