Method for acquiring Ethernet data frame, device and base station

Abstract

The invention discloses a method for acquiring an Ethernet data frame. The method comprises the following step that: when a baseband unit and a radio frequency unit exchange common public radio interference (CPRI) protocol data frames, the baseband unit or the radio frequency unit extracts the Ethernet data frame in the CPRI protocol data frame and sends the Ethernet data frame to an acquisition device which is externally connected with the baseband unit or the radio frequency unit. The invention also provides the corresponding device and a base station. By the method for acquiring the Ethernet data frame, the device and the base station, the Ethernet data frame is easy and convenient to acquire.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and base station for acquiring Ethernet data frames. Background technique [0002] In the base station system of mobile communication, a single base station is generally divided into a baseband unit and a radio frequency unit. When building a single base station, radio frequency units can be combined with baseband units to form a centralized base station, or they can be placed independently to form a distributed base station system. [0003] With the development of mobile communication technology, especially in the third-generation mobile communication system, the traditional base station that integrates baseband unit and radio frequency unit is difficult to meet the needs of rapid network construction. Therefore, most of the new generation of base stations use distributed base station systems, that is, the formation of figure 1 The new networking architecture of a ba...
