    Abstract: The invention relates to a technology for decreasing or eliminating communication overhead in a communication system for communicating packet data. A gateway compresses IP header (331 ), UDP/Real-time, and Transport Protocol (RTP) header and associates with the data to transmit the data to a base station. The base station compresses the GTP related header (320) using a RObust Header Compression (ROHC) scheme. UDP/RTP header (332) is integrated with the plurality of data packets, generates SCTP header. The base station generates header decompression information, and inserts it into a Packet Data Convergence Protocol (PDCP) of the LTE L2 header (310) as a header compression (HC) header (335). The relay receives the data from the base station using the Layer (Ll) and the Layer (L2) of a 3GPP LTE protocol. The base station transmits, via the relay, the header decompression information to a terminal accessing the relay, and the terminal can decompress the compressed GTP header (323) using the header decompression information.

    Abstract translation: 本发明涉及用于减少或消除用于传送分组数据的通信系统中的通信开销的技术。 网关压缩IP报头（331），UDP /实时和传输协议（RTP）报头，并与数据相关联，以将数据发送到基站。 基站使用RObust Header Compression（ROHC）方案来压缩GTP相关的报头（320）。 UDP / RTP报头（332）与多个数据分组集成，生成SCTP报头。 基站产生报头解压缩信息，并将其插入LTE L2报头（310）的分组数据汇聚协议（PDCP）中作为报头压缩（HC）报头（335）。 中继器使用3GPP LTE协议的层（L1）和层（L2）从基站接收数据。 基站通过中继将报头解压缩信息发送到接入中继的终端，终端可以使用报头解压缩信息解压缩压缩的GTP报头（323）。

    Abstract: PURPOSE: An MBMS(Multimedia Broadcast Multicast Service) broadcasting service receiving system and a method thereof are provided to receive an MBMS by a unicast bearer using synchronization information which is the same as a multicast bearer according to wireless quality or performance of a terminal. CONSTITUTION: When a selected broadcast service is not transmitted to a first bearer, a transmission channel setting unit(130) sets a second bearer by a transmission channel. When the selected broadcast service is transmitted to both the first bearer and the second bearer, the transmission channel setting unit sets the first bearer about a portion of the selected broadcast service as a transmission channel. The transmission channel setting unit sets the second bearer about the other portions of the selected broadcast service as a transmission channel. A broadcast service receiving unit(140) receives an MBMS broadcast service which is selected according to the setup transmission channel.

    Abstract: PURPOSE: A control system for MBMS(Multimedia Broadcast Multicast Service) service support is provided to select efficient service area or base station according to the configuration scenario of a service net for broadcasting of multimedia service and multi transmission in a cellular system, thereby providing a MBMA service to a terminal. CONSTITUTION: A transmitting unit(310) transmits a MBMS service request message to a first base station. Based on the MBMS service request message, a receiving unit(330) receives MBMS data from the first base station. In other words, the receiving unit receives MBMS data from a second base station(350) neighbor to the first base station. A handover execution unit(320) performs handover from the first base station to the second base station.
