PURPOSE: A method and apparatus for processing packet data are provided to perform encoding suitable for a data source, accurately control the amount of data transmission and effectively control a network.

CONSTITUTION: A wired/wireless section discriminating unit(80) is positioned in a UTRAN(Universal Mobile Telecommunications Network Terrestrial Radio Access Network)(200) and logically positioned at an upper position of a RAN(Radio Access Network) protocol layer. The UTRAN(200) is a network for matching a wired section and a wireless section. The wired/wireless section discriminating unit(80) discriminates a transmission section of an RTP(Real-time Transport Protocol) packet by a wired section and a wireless section and processes the RTP packet transferred through the wired section from a core network(300), and transmits an RTCP(RTP Control Protocol) packet from an end of the wired section to a data source(70) to perform operations of the RTP and the RTCP. The wired/wireless section discriminating unit(80) broadcasts and/or multicasts the RTP packets received from the data source(70) to multiple terminals(100) through a downlink radio channel. Upon receiving the RTP packets, the terminals(100) transmits receiving state information with respect to the received RTP packets to the wired/wireless section discriminating unit(80) through the wireless section.
