Abstract:
1. A method for processing incoming data in a mobile communication system supporting high-speed data communication, the method comprising the steps of: analyzing, by a Central Processing Unit (CPU) included in a User Equipment (UE) apparatus, data that has been received from a Node B and decoded and transferring information on the analyzed data to an embedded Direct Memory Access (DMA) of a modem included in the UE apparatus; transferring, by the embedded DMA of the modem, payload data of the decoded data to an internal memory included in the UE apparatus using the information; performing, by the CPU, a Medium Access Control (MAC) process and a Radio Link Control (RLC) process; performing a Packet Data Convergence Protocol (PDCP) process using a position and size of payload data of a PDCP packet when the PDCP packet is included in the RLC process; transferring, by an embedded DMA of an external interface device included in the UE apparatus, payload data of an Internet Protocol (IP) packet to the internal memory when the IP packet is included in the PDCP process; and performing, by the embedded DMA of the external interface device, an interrupt process while receiving an external interface device interrupt, wherein the steps performed by the embedded DMA of the modem, the embedded DMA of the external interface device and the CPU are performed in parallel, respectively, and wherein the interrupt process comprises at least one of a flag setting process, an encryption process, a decryption process and a data alignment process.
