| 摘要 |
The invention disclosed herein relates to a base station transceiver sub-system, where when data is transmitted/received via radio in predetermined time long frame units, one frame offset of a plurality of frame offsets after dividing the time length is allocated to each traffic channel, and the radio interface 50 and the ATM interface are synchronized using this frame offset. In this base station transceiver sub-system, the fluctuation of cells on an ATM line is tolerated for a predetermined frame offset width, and considering the cell transmission enabled band according to said tolerated fluctuation width, a same frame offset is allocated to a plurality of traffic channels so as to control the generation of fragmentation.
