1. A method for providing simultaneous multiple multimedia service, the method comprising the steps of:
- receiving a request for establishment of at least two multimedia sessions of a terminal performing multimedia service;
determining whether the terminal supports simultaneous multiple multimedia sessions;
determining whether a pre-defined setup of the terminal is set when the terminal supports multiple multimedia sessions, the pre-defined setup being for adjusting sizes of at least two multimedia data to be transmitted through the simultaneous multiple multimedia sessions;
adjusting sizes of the at least two multimedia data to be transmitted to the terminal based on the pre-defined setup when the pre-defined setup of the terminal is set, the adjusted sizes of the multimedia data being adapted to provide simultaneous multiple multimedia service; and
transmitting the adjusted data to the terminal.
