Abstract

The invention provides a data transmission method, and data forwarding equipment and system. The data transmission method comprises the steps: first equipment receives grouped data transmitted by first packet-processing switching PHS network equipment through a first Ethernet interface, and receives in-phase orthogonal I / Q data transmitted by a first unit through a first CPRI (common public radio interface) port, wherein the format of I / Q data accords with the CPRI protocol; the first equipment converts the grouped data into the conversion data, wherein the format of the conversion data accords with the CPRI protocol; the first equipment enables the conversion data and the I / Q data to be loaded in a transmission resource of the CPRI channel, and to be transmitted to second equipment; the first PHS network equipment is PHS server-side equipment, and the first unit is a baseband unit; or the first PHS network equipment is PHS client-side equipment, and the first unit is an RRU (remote radio unit).

Description

technical field [0001] Embodiments of the present invention relate to the field of communications, and in particular, to a data transmission method and a data forwarding device and system. Background technique [0002] In the wireless base station equipment, a baseband unit (Baseband Unit, BBU) and a remote radio unit (Remote Radio Unit, RRU) are connected through a Common Public Radio Interface (Common Public Radio Interface, CPRI) port. The main feature of the CPRI port is the separation of baseband and radio frequency. [0003] Devices using CPRI ports, such as BBUs and RRUs, can work in frequency division duplex (Frequency Division, FDD) mode and time division duplex (Time Division Duplex, TDD) mode. The CPRI port is a bidirectional full-duplex interface. [0004] The inventor of the present invention found in the process of implementing the present invention that the transmission bandwidth utilization rate of the existing CPRI port is low.
