FEMTOCELL ACCESS NODE, FEMTOCELL SYSTEM, AND DATA TRANSMISSION METHOD FOR THE SYSTEM

摘要

Disclosed are a femtocell access node, a femtocell system, and a data transmission method for the system. When a transmitter terminal transmits data to a receiver terminal, the femtocell access node of the transmitter side detects the current access status of the receiver terminal, and determines the transmission format of data transmitted from the transmitter terminal to the receiver terminal in accordance with the detected access status. Particularly, the present invention modifies only the L1/L2 protocol portion and transmits data to the receiver terminal via an internet protocol (IP) network, in the event the receiver terminal is directly or indirectly accessible by the IP network. According to the present invention, the load on a core network is reduced so as to increase the overall capacity of the system and shorten the path for data traffic.
