Announcement broadcasting apparatus in universal mobile telecommunication system

An announcement broadcasting apparatus in a Universal Mobile Telecommunication System (UMTS), wherein the UMTS is comprised of a mobile switching center, a base station and a mobile station, and the mobile switching center includes a higher-order processor connected to the announcement broadcasting apparatus, the announcement broadcasting apparatus comprising:

• a message sending/receiving interface, a message storage unit, a unique message information storage unit and a controller connected to the higher-order processor;
• said message storage unit having announcement messages stored therein as phoneme-unit pattern data under control of said controller in response to a message storage request from said higher-order processor;
• said unique message information storage unit having information stored therein regarding the location and size of each of the stored announcement messages and outputting the stored information about the location and size of a corresponding one of said announcement messages to said controller in response to an announcement message sending request sent to said controller from said higher-order processor;
• said controller receiving, from the higher-order processor, phoneme-unit pattern data of an announcement message to be sent, said phoneme-unit pattern data corresponding to separate phoneme-unit data stored in said message storage unit to form an edited message;
• said controller receiving, from the higher-order processor, an announcement message number of an announcement message to be sent, said announcement number corresponding to a fixed message stored in said message storage unit;
• said message sending/receiving interface being operated under the control of the controller, in response to a message sending request from the higher-order processor, to read 8-bit parallel data, corresponding to the fixed message or the edited message, from the message storage unit, convert the read 8-bit parallel data into serial data and send the converted serial data to the higher-order processor via said controller.
