Abstract

Disclosed are a packet data transfer apparatus and a packet data transfer method in a mobile communication system. In the mobile communication system, the packet data transfer apparatus reduces a load of a protocol stack processor, which causes performance degradation due to a considerable time taken to transfer a large amount of packet data to a memory of a packet processor from Ethernet, so that the clock speed of the processor can be lowered. Accordingly, it is possible to implement a modem for mobile communication using low power. Further, the packet data transfer apparatus is positioned between a processor and a memory so that the processor does not perform packet data transfer from the outside to an internal memory of the process or packet data transfer from the internal memory of the process to the outside. Accordingly, it is possible to reduce packet data transfer of the processor.
