PURPOSE: A method for realizing communication between BSCs(Base Station Controllers) using an E1 interface in a WLL system is provided to exclude a GCIN(Global CDMA Interconnection Network) structure from a WLL system, and to perform communication between BSCs by using an E1 interface, thereby reducing the number of shelves, boards, and cables. CONSTITUTION: If a terminal requests a packet(ST101), a BTS confirms the requested packet(ST102). If the requested packet is a self BSC packet(ST103), the BTS processes the requested packet in a self BSC(ST104). If the requested packet is other BSC packet(ST103), the BTS transmits the requested packet to an E1 interface board(ST105). The E1 interface board transmits the received packet to an E1 link(ST106). Other BSC receiving the packet from the E1 link processes the packet(ST107). |
