- determining at least one of a voice codec mode, byte-alignment information about a byte-alignment scheme of a voice packet, a requested bandwidth and a codec type used for processing a voice call in a procedure of establishing a call between a terminal and a core network;
forming a packet data protocol context establishing message including at least one of the codec type, the byte-alignment information and the voice codec mode in order to establish a bearer for a packet call;
transmitting the formed packet data protocol context establishing message to the core network from the terminal; and
transmitting a radio bearer establishing message from an access network to the terminal, the radio bearer establishing message comprising at least one of a radio link packet size set determined based on the codec type, the byte-alignment information and the voice codec mode, the access network connecting the terminal with the core network,wherein the codec type indicates whether the codec type of the voice call is an adaptive multi-rate codec, andwherein the byte-alignment information represents a bandwidth efficient scheme for byte-aligning an overall size of a header and a payload included in the voice packet, and an octet aligned scheme for individually byte-aligning the header and the payload.
