Embodiment Construction

[0058] The embodiment of the present invention can convert the first data sent by the first device in the wireless base station system to the second device in the wireless base station system into a first Ethernet message; and / or will be sent by the second device The second Ethernet packet obtained by converting the second data for the first device is converted into the second data. Since the embodiment of the present invention can convert between Ethernet messages and data, the integration of the wireless base station system and the Ethernet transmission protocol can be realized, and the data transmission between the RE and the REC using the Ethernet can be realized, thereby reducing costs.

[0059] Taking CPRI as an example, such as figure 1 As shown, in the schematic diagram of the mapping relationship between the embodiment of the present invention and the CPRI protocol, the physical layer of CPRI corresponds to the Ethernet physical layer of the embodiment of the present ...

Abstract

The application relates to the wireless communication technology field, in particular to a method, a system and a device for data transmission, which are used to solve the problems in the prior art that due to the interface protocol limit between an REC and an RE, the communication between the REC and the RE in a wireless base station system can not utilize the existing transmission networking resource, so that the resources can not be saved very well, and the cost is not reduced. The method of the application comprises the steps of transforming the first data sent by a first device in the wireless base station system to a second device in the wireless base station system into a first Ethernet report, sending the first Ethernet report to the second device; and/or receiving the second Ethernet report obtained by transforming the second data sent by the second device to the first device, and transforming the second Ethernet report into the second data. The application can realize the fusion of the wireless base station system and an Ethernet transmission protocol.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for transmitting data. Background technique [0002] The wireless base station system includes a BBU (Base Band Unit, base band unit) and an RRU (Remote Radio Unit, remote radio unit). Among them, the BBU is also called REC (Radio Equipment Controller, Radio Euipment Controller), and the RRU is also called RE (Radio Equipment, Radio Euipment). The RE is connected to the REC through an optical interface or an SFP high-speed cable, and uses the CPRI (Common Public Radio Interface) protocol or the OBSAI (Open Base Station Architecture Initiative) protocol for data transmission. For the connection schematic diagram using optical fiber in the prior art, please refer to figure 1 . [0003] At present, the transmission network is constantly developing, mainly from 1GE (1Gigabit Ethernet, Gigabit Ethernet) to higher 10GE (10Gigabit Ethernet, 10 Gigab...
