Abstract

The present invention discloses a device and method for multi-standard data transmission based on Open Base Station Architecture Initiative (OBSAI) protocol. Said device includes: baseband units, used for adapting baseband data and signaling data into OBSAI bit streams according to the correspondence between said wireless standards, then outputting the bit streams to a cross unit, and deframing the OBSAI bit streams sent from the cross unit according to the correspondence between said wireless standards, to obtain baseband data and signaling data; the cross unit, used for splitting the OBSAI bit streams sent from the baseband units or Radio Frequency (RF) units into data and signaling bit streams, and according to the destination addresses of the split bit streams, cross-sending said bit streams to the optical interfaces or baseband units corresponding to the destination addresses; the RF units, used for locally deframing or transferring the received OBSAI bit streams according to the destination addresses of the bit streams, and transferring the locally generated OBSAI bit streams according to the destination addresses of the bit streams. The device and method provided by the present invention enables transmission of 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 (TimeDivision-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) In 2007, WIMAX (Worldwide Interoperability for Microwave Access, Global Microwave Interconnection Access) was among them, making there are four 3G standards, plus 2G GSM / CDMA and quasi-4G LTE (Long Term Evolution (Long Term Evolution), IEEE802.16M, etc., there are as many as eight wireless standards currently in use or to be used, and it is a burden for many equipment manufactur...
