Abstract

The invention provides a self-adapting method and device for a base band unit equipment RRU interface protocol based on an FPGA. The FPGA comprises a type register. The method comprises the steps that an RRU loads the FPGA; the FPGA comprises one or more interface protocol types; the RRU has the access to a BBU by adopting any interface protocol type; the RRU detects the current interface protocol type of the BBU; the RRU records corresponding type marks in the cache type register according to the current interface protocol type; the RRU carries out configuration according to the interface protocol types corresponding to the type marks. The method and device are used for detecting and adjusting the interface protocol, guaranteeing uniformity of the protocol and an opposite-end equipment interface protocol, lowering complexity for achieving normal communication, shortening the transformation time that a TD-SCDMA base station is evolved to a TD-LTE base station, and guaranteeing the normal communication of equipment in common networking.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method for self-adapting RRU interface protocol based on FPGA baseband unit equipment, and a device for self-adapting RRU interface protocol based on FPGA baseband unit equipment. Background technique [0002] There is a widely used distributed structure in TD-LTE (Time Division Long Term Evolution), which is composed of BBU (Remote Radio Unit) and RRU (Building Base band Unit, indoor baseband processing). Unit) constitutes the current more popular base station system architecture. [0003] At present, during the process of RRU accessing BBU through optical fiber according to specific RRU interface protocol, RRU needs to support smooth evolution from TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) standard to TD-LTE Standard requirements have increased the types of RRU interface protocols supported by the RRU. The RRU side needs to be able...
