    • A method for branching data in a mobile communication terminal to perform data communication between a mobile station and a network which have media access control sublayers. In a data sending mode, each of the media access control sublayers of the mobile station and network attaches logical channel types based on traffic characteristic information and a radio bearer status to a media access control header contained in data to be sent. Then, each of the media access control sublayers branches the data to be sent, to transport channels corresponding to the attached logical channel types. In a data receiving mode, each of the media access control sublayers determines logical channels corresponding to logical channel types of a media access control header contained in received data. Then, each of the media access control sublayers branches the received data to the determined logical channels. Each of the media access control sublayers performs mapping and multiplexing/demultiplexing between logical channels and transport channels according to traffic characteristics to branch data. Therefore, it is possible to efficiently provide various multimedia and packet services.
    • 一种用于在移动通信终端中分支数据以执行移动站和具有媒体访问控制子层的网络之间的数据通信的方法。 在数据发送模式中,移动站和网络的每个媒体接入控制子层将基于业务特性信息和无线承载状态的逻辑信道类型附加到包含在要发送的数据中的媒体访问控制头。 然后,每个媒体访问控制子层将要发送的数据分支到与所附加的逻辑信道类型相对应的传输信道。 在数据接收模式中,每个媒体接入控制子层确定与接收数据中包含的媒体接入控制报头的逻辑信道类型对应的逻辑信道。 然后,每个媒体访问控制子层将所接收的数据分支到所确定的逻辑信道。 每个媒体访问控制子层根据到分支数据的流量特性来执行逻辑信道和传输信道之间的映射和复用/解复用。 因此,可以有效地提供各种多媒体和分组业务。

    • A method for formatting a signal in a mobile communication system by appending a plurality of medium access control headers to a plurality of medium access control-service data units for data transfer between a mobile station and network in the mobile communication system. If the service data units have the same characteristics, a medium access control-protocol data unit is formed by successively coupling the service data units to any one of the medium access control headers. If the service data units have different characteristics, the protocol data unit is formed by sequentially coupling each of the service data units and each of the medium access control headers. The formed protocol data unit is then transformed into a transport block with a predetermined size. A medium access control sublayer formats medium access control-protocol data units according to transport channel characteristics in peer-to-peer communication in such a manner that the protocol data units can have different formats with respect to different transport channels. This makes it possible to provide more efficient functions.
    • 一种用于在移动通信系统中格式化信号的方法,其通过将多个介质访问控制报头附加到用于在移动通信系统中的移动站和网络之间的数据传输的多个介质访问控制服务数据单元。 如果服务数据单元具有相同的特性,则通过将服务数据单元连续地耦合到任何一个媒体访问控制报头来形成媒体访问控制协议数据单元。 如果服务数据单元具有不同的特性,则通过顺序耦合每个服务数据单元和每个介质访问控制报头来形成协议数据单元。 形成的协议数据单元然后被转换成具有预定大小的传输块。 媒体接入控制子层根据对等通信中的传输信道特性,按照协议数据单元相对于不同传输信道具有不同格式的方式来格式化媒体接入控制协议数据单元。 这使得可以提供更有效的功能。
