초록 ▼

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.

What is claimed is: 1. A method of processing data in a medium access control (MAC) layer of a receiving entity in a mobile communications system, comprising the steps of: receiving a plurality of medium access control protocol data units (MAC PDUs) from a physical layer through a transport channel to which a plurality of logical channels are mapped, each MAC PDU having data and a header including information indicative of a logical channel type, wherein the plurality of logical channels are located between a radio link control (RLC) layer and the MAC layer, and the transport channel is located between the MAC layer and the physical layer; and transferring the data of each medium access control protocol data unit (MAC PDU) to the RLC layer through one of the plurality of logical channels based on the information indicative of the logical channel type of each MAC header. 2. The method of claim 1, wherein the transport channel is a forward access channel which is a downlink channel. 3. The method of claim 1, wherein the transport channel is a random access channel (RACH) which is a uplink channel. 4. The method of claim 1, wherein the transport channel is a downlink shared channel (DSCH). 5. The method of claim 2, wherein the plurality of logical channels include a common control channel (CCCH) and a dedicated control channel (DCCH). 6. The method of claim 3, wherein the plurality of logical channels include a common control channel (CCCH) and a dedicated control channel (DCCH). 7. The method of claim 6, wherein the dedicated logical channel is one of a dedicated control channel (DCCH) and a dedicated traffic channel (DTCH). 8. The method of claim 4, wherein the plurality of logical channels include a dedicated control channel (DCCH) and a dedicated traffic channel (DTCH). 9. The method of claim 5 or 8, wherein the receiving entity is a mobile terminal communicating with a network in the mobile communications system. 10. The method of claim 6 or 7, wherein the receiving entity is a network communicating with at least one mobile terminal in the mobile communications system.
