Abstract: PURPOSE: An apparatus and a method for transmitting/receiving multimedia broadcast and multicast service(MBMS) in a wireless communication system are provided to minimize the unnecessary reception of an MBMS control channel(MCCH). CONSTITUTION: An MCCH configuration unit generates a sub-header by receiving control information related to MBMS traffic. The MCCH configuration unit generates medium access control(MAC) packet using the sub-header. The MCCH configuration unit maps the MAC packet with a logical MCCH. A scheduler(321) schedules the transmission timing and priority of the MBMS traffic channel(MTCH) and the MCCH. A transmission unit(341) maps either of the MTCH or MCCH with a physical downlink shared channel(PDSCH). The transmission unit provides identification information for transmitting the MBMS to the PDSCH a physical downlink control channel.

Abstract: A method for controlling uplink IP packet filtering in a mobile terminal in a 3GPP Evolved Packet System (EPS) is provided, including an information receiving operation of receiving IP address information allocated to user equipment, and filtering information required for delivering an uplink IP packet received from the user equipment; and a filtering operation for determining which packet data network and a bearer the IP packet is delivered to, based on the IP address information and the filtering information. In a 3GPP evolved packet system supporting a default bearer function, a packet data network to which an uplink IP packet is delivered and a bearer identifier can be efficiently determined when the user equipment simultaneously accesses one or more packet data networks and is allocated several IP addresses, resulting in effective uplink packet filtering.
