Abstract
A communication method between the units of a distributed base station system, characterized by comprising: at the transmitting end, mapping a CPRI link to a GFP-T frame; encapsulating the GFP-T frame into SDH virtual containers to form a STM-N frame; and transmitting the STM-N frame via a SDH line, and at the receiving end, receiving the STM-N frame transmitted via the SDH line; separating the SDH virtual containers from the STM-N frame; extracting the GFP-T frame from the SDH virtual containers; reproducing the CPRI link from the GFP-T frame.
