A data transmission method, device and network system

Abstract

The present invention discloses a data transmission method, apparatus and network system, involving the field of communication, can support multi-service flow corresponding to the CPRI data in multiple RRU, multi-BBU through the existing switching equipment point-to-point, point-to-multipoint, multi-point to multipoint between the arbitrary networking exchange, not only reduce the cost of CPRI network networking, but also improve the flexibility of CPRI networking. Specific implementation methods include: the transmitting device receives CPRI data; The CPRI data includes CPRI data for at least one business flow; From the CPRI data, the CPRI data payload corresponding to each service flow is analyzed, and based on the special processing frame header of each service flow, the CPRI data payload of the corresponding service flow is encapsulated separately, and the packet message of each service flow is obtained; Wherein, the dedicated processing frame header contains the corresponding business flow identifier of the service flow; Packet messages of each traffic flow are transmitted to the receiving device. The present invention for transmitting CPRI data in Ethernet.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, device and network system. Background technique [0002] In the current wireless communication field, CPRI (Common Public Radio Interface, common public radio interface) is the current wireless communication industry's wireless base station equipment BBU (Building Base band Unit, indoor baseband processing unit) and RRU (Radio Remote Unit, radio remote A communication interface standard between units). Among them, the above-mentioned CPRI interfaces must be interconnected through a dedicated CPRI network. The existing CPRI network networking methods mainly include: point-to-point optical fiber transmission connection through Czochralski optical fiber, or use special CPRI switching equipment for BBU and Radio frequency or baseband interconnection between RRUs. However, for point-to-point transmission connections through optical fibers, it is necessar...

Problems solved by technology

However, the above-mentioned CPRI data transmission process is only the transmission of the entire CPRI data frame, and each transmission can only transmit the CPRI data frame corresponding to a single service flow, so that the entire process can only carry out point-to-point data transmission between the RRU and the BBU. Insufficient networking flexibility, not suitable for point-to-multipoint data transmission between multiple RRUs and multiple BBUs
