IR frame format conversion method and device for a baseband processing unit bbu interface board

Abstract

The embodiment of the invention provides a method of IR (Interface between the RRU (Remote Radio Unit) and the BBU) frame format conversion of BBU (Base Band Unit) interface board. The method comprises: converting the IR frame format of a BBU interface board to a first IR frame format; sending version updating indication message version to the RRU to update indication information, wherein the RRU is configured to employ the version updating indication message to convert the IR frame format to a second IR frame format; and converting the IR frame format of the BBU interface board to the second IR frame format. In the embodiment, the BBU interface board is adaptively converted to the IR frame format being the same as the RRU to allow the RRU to receive the version updating indication message sent by the BBU in an original IR frame format. After the RRU employs the version updating indication message to update the IR frame format, and the IR frame format of the BBU interface board is updated to allow the RRU to access the RRU in a new IR frame format. Artificial near-end direct-connection with the RRU is not needed to perform updating of the RRU to allow the RRU to be accessed so as to greatly reduce the manual operation cost and greatly reduce the increasing of engineering complexity and increasing of construction time caused by artificial maloperation.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to an IR frame format conversion method of a baseband processing unit BBU interface board and an IR frame format conversion device of the baseband processing unit BBU interface board. Background technique [0002] With the continuous development of wireless mobile communication technology, the remote radio unit RRU (RemoteRadio Unit) in the base station system is also constantly updated, and a variety of IR frame formats have emerged to meet the needs of various technologies. [0003] The IR (Interface between the RRU and the BBU) interface is the interface between the RRU and the BBU. The RRU is connected to the baseband processing unit BBU (Base Band Unit) through an optical fiber. It is necessary to ensure that the IR frame format of the RRU and the BBU interface board is consistent. To access the BBU. [0004] When building a new base station, if an old R...
