METHOD FOR SUPPLYING STILL IMAGE TELEPHONE SERVICE BY USING MULTIPLE RADIO ACCESS BEARER, CONCERNED WITH TRANSMITTING VOICE IN EXISTING CIRCUIT SERVICE WAY AND TRANSMITTING STILL IMAGE IN PACKET DATA SERVICE WAY

摘要

PURPOSE: A method for supplying a still image telephone service by using a multi-RAB(Radio Access Bearer) is provided to transmit a voice in an existing circuit service way, and to transmit a still image in a packet data service way, thereby transmitting a figure of other party as a still image during a call while maintaining an existing sound quality level. CONSTITUTION: A system sets a circuit-based bearer voice call(S10). An originating terminal sets a bearer packet call to a core network(S20). The originating terminal transmits a still image to a packet channel by using the packet channel(S30). When setting the bearer packet call, the originating terminal automatically sets the packet call. A bearer voice call and the packet call are made by using a multi-RAB way. The originating terminal periodically transmits the still image by using the packet channel.
