Abstract

The invention discloses device and method for multi-standard data transmission based on the OBSAI (open base station architecture initiative) protocol. The device comprises a base-band unit, a cross-unit and a radio-frequency unit, wherein the base-band unit is used for fitting base-band data and signaling data corresponding to standards into an OBSAI code stream and then outputting to the cross-unit and for performing the frame solution of an OBSAI code stream from the cross-unit to obtain base-band data and signaling data; the cross-unit is used for splitting an OBSAI code stream from the base-band unit or the radio-frequency unit to form base-band data and signaling data and transmitting the code stream in a crossed manner onto an optical port or the base-band unit corresponding to a target address according to a target address of the code stream after splitting; and the radio-frequency unit is used for performing the local frame solution or the forwarding of the received OBSAI code stream according to a target address of the received code stream and forwarding a locally-generated OBSAI code stream according to a target address of the locally-generated code stream. The device provided by the invention can achieve the transmission of the multi-standard data.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a multi-standard data transmission device and method based on the OBSAI (Open Base Station Architecture Initiative, Open Base Station Architecture) protocol. Background technique [0002] 3G standards originally included WCDMA (Wideband CDMA, Wideband Code Division Multiple Access), CDMA2000 (Code Division Multiple Access 2000, Code Division Multiple Access 2000), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, time division synchronous code division In 2007, WIMAX (Worldwide Interoperability for Microwave Access, Global Microwave Interconnection Access) was among them, making 4 3G standards, plus 2G GSM / CDMA and quasi-4G LTE (Long Term Evolution, IEEE802.16M, etc., there are as many as eight wireless standards currently in use and to be used, and it is a burden for many equipment manufacturers to support so many standards at the same time....
