Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/188184
Kind Code:
A1
Abstract:
Disclosed are a data transmission method and device. The method comprises: when N radio remote units (RRU) uplink transmit data to a building baseband unit (BBU), receiving and then encapsulating, by an OLT, common public radio interface (CPRI) data of the N RRUs; performing, by the OLT, convergence on the encapsulated CPRI data of the N RRUs, then forwarding, by the OLT, the same to the BBU; and parsing, by the BBU, the converged data by the OLT to acquire the encapsulated CPRI data of the N RRUs, and respectively decapsulating, by the BBU, the acquired data to acquire the CPRI data of the N RRUs. When the BBU downlink transmits data to the N RRUs, the OLT receives the CPRI data encapsulated by the BBU and sent to the N RRUs, then decapsulates the encapsulated data, and respectively forwards to the N RRUs the CPRI data acquired from decapsulation and sent to the N RRUs by the BBU.
